Intensive Care and its Discontents: Psychiatric Illness in the Critically Ill.

PubMed

Hashmi, Ali M; Han, Jin Y; Demla, Vishal

2017-09-01

Critically ill patients can develop a host of cognitive and psychiatric complaints during their intensive care unit (ICU) stay, many of which persist for weeks or months following discharge from the ICU and can seriously affect their quality of life, including their ability to return to work. This article describes some common psychiatric problems encountered by clinicians in the ICU, including their assessment and management. A comprehensive approach is needed to decrease patient suffering, improve morbidity and mortality, and ensure that critically ill patients can return to the highest quality of life after an ICU stay.

Integration of Palliative Care in Chronic Critical Illness Management

PubMed Central

Nelson, Judith E; Hope, Aluko A

2016-01-01

Palliative care is an essential component of comprehensive care for all patients with chronic critical illness, including those receiving restorative or life-sustaining therapies. Core elements include alleviation of symptom distress, communication about care goals, alignment of treatment with the patient’s values and preferences, transitional planning, and family support. Here we address strategies for assessment and management of symptoms, including pain, dyspnea, and depression, and for assisting patients to communicate while endotracheally intubated. We also discuss approaches to optimize communication among clinicians, patients, and families about care goals. Challenges for supporting families and planning for transitions between care settings are identified, while the value of interdisciplinary input is emphasized. We review “consultative” and “integrative” models for integrating palliative care and restorative critical care. Finally, we highlight key ethical issues that arise in the care of chronically critically ill patients and their families. PMID:22663973

Setting the vision: applied patient-reported outcomes and smart, connected digital healthcare systems to improve patient-centered outcomes prediction in critical illness.

Prediction models in critical illness are generally limited to short-term mortality and uncommonly include patient-centered outcomes. Current outcome prediction tools are also insensitive to individual context or evolution in healthcare practice, potentially limiting their value over time. Improved prognostication of patient-centered outcomes in critical illness could enhance decision-making quality in the ICU. Patient-reported outcomes have emerged as precise methodological measures of patient-centered variables and have been successfully employed using diverse platforms and technologies, enhancing the value of research in critical illness survivorship and in direct patient care. The learning health system is an emerging ideal characterized by integration of multiple data sources into a smart and interconnected health information technology infrastructure with the goal of rapidly optimizing patient care. We propose a vision of a smart, interconnected learning health system with integrated electronic patient-reported outcomes to optimize patient-centered care, including critical care outcome prediction. A learning health system infrastructure integrating electronic patient-reported outcomes may aid in the management of critical illness-associated conditions and yield tools to improve prognostication of patient-centered outcomes in critical illness.

Managing social awkwardness when caring for morbidly obese patients in intensive care: A focused ethnography.

Hales, Caz; de Vries, Kay; Coombs, Maureen

2016-06-01

Critically ill morbidly obese patients pose considerable healthcare delivery and resource utilisation challenges in the intensive care setting. These are resultant from specific physiological responses to critical illness in this population and the nature of the interventional therapies used in the intensive care environment. An additional challenge arises for this population when considering the social stigma that is attached to being obese. Intensive care staff therefore not only attend to the physical and care needs of the critically ill morbidly obese patient but also navigate, both personally and professionally, the social terrain of stigma when providing care. To explore the culture and influences on doctors and nurses within the intensive care setting when caring for critically ill morbidly obese patients. A focused ethnographic approach was adopted to elicit the 'situated' experiences of caring for critically ill morbidly obese patients from the perspectives of intensive care staff. Participant observation of care practices and interviews with intensive care staff were undertaken over a four month period. Analysis was conducted using constant comparison technique to compare incidents applicable to each theme. An 18 bedded tertiary intensive care unit in New Zealand. Sixty-seven intensive care nurses and 13 intensive care doctors involved with the care and management of seven critically ill patients with a body mass index ≥40kg/m(2). Interactions between intensive care staff and morbidly obese patients were challenging due to the social stigma surrounding obesity. Social awkwardness and managing socially awkward moments were evident when caring for morbidly obese patients. Intensive care staff used strategies of face-work and mutual pretence to alleviate feelings of discomfort when engaged in aspects of care and caring. This was a strategy used to prevent embarrassment and distress for both the patients and staff. This study has brought new understandings about intensive care situations where social awkwardness occurs in the context of obesity and care practices, and of the performances and behaviours of staff in managing the social awkwardness of fat-stigma during care situations.

The objective of this study is to determine if shared decisions for managing non-critical chronic illness, made through an online biomedical technology intervention, us feasible and usable. The technology intervention incorporates behavioural and decision theories to increase patient engagement, and ultimately long term adherence to health behaviour change. We devised the iheart web intervention as a "proof of concept" in five phases. The implementation incorporates the Vaadin web application framework, Drools, EclipseLink and a MySQL database. Two-thirds of the study participants favoured the technology intervention, based on Likert-scale questions from a post-study questionnaire. Qualitative analysis of think aloud feedback, video screen captures and open-ended questions from the post-study questionnaire uncovered six main areas or themes for improvement. We conclude that online shared decisions for managing a non-critical chronic illness are feasible and usable through the iheart web intervention.

The number of patients living with hematological malignancies (HMs) has increased steadily over time. This is the result of intensive and effective treatments that also increase the probability of infiltrative, infectious or toxic life threatening event. Over the last two decades, the number of patients with HMs admitted to the ICU increased and their mortality has dropped sharply. ICU patients with HMs require an extensive diagnostic workup and the optimal use of ICU treatments to identify the reason for ICU admission and the nature of the complication that explains organ dysfunctions. Mortality of ARDS or septic shock is up to 50%, respectively. In this review, the authors share their experience with managing critically ill patients with HMs. They discuss the main aspects of the diagnostic and therapeutic management of critically ill patients with HMs and argue that outcomes have improved over time and that many classic determinants of mortality have become irrelevant.

Use of EEG Monitoring and Management of Non-Convulsive Seizures in Critically Ill Patients: A Survey of Neurologists

PubMed Central

Abend, Nicholas S.; Dlugos, Dennis J.; Hahn, Cecil D.; Hirsch, Lawrence J.; Herman, Susan T.

2010-01-01

Background Continuous EEG monitoring (cEEG) of critically ill patients is frequently utilized to detect non-convulsive seizures (NCS) and status epilepticus (NCSE). The indications for cEEG, as well as when and how to treat NCS, remain unclear. We aimed to describe the current practice of cEEG in critically ill patients to define areas of uncertainty that could aid in designing future research. Methods We conducted an international survey of neurologists focused on cEEG utilization and NCS management. Results Three-hundred and thirty physicians completed the survey. 83% use cEEG at least once per month and 86% manage NCS at least five times per year. The use of cEEG in patients with altered mental status was common (69%), with higher use if the patient had a prior convulsion (89%) or abnormal eye movements (85%). Most respondents would continue cEEG for 24 h. If NCS or NCSE is identified, the most common anticonvulsants administered were phenytoin/fosphenytoin, lorazepam, or levetiracetam, with slightly more use of levetiracetam for NCS than NCSE. Conclusions Continuous EEG monitoring (cEEG) is commonly employed in critically ill patients to detect NCS and NCSE. However, there is substantial variability in current practice related to cEEG indications and duration and to management of NCS and NCSE. The fact that such variability exists in the management of this common clinical problem suggests that further prospective study is needed. Multiple points of uncertainty are identified that require investigation. PMID:20198513

Introduction and executive summary: care of the critically ill and injured during pandemics and disasters: CHEST consensus statement.

Natural disasters, industrial accidents, terrorism attacks, and pandemics all have the capacity to result in large numbers of critically ill or injured patients. This supplement provides suggestions for all of those involved in a disaster or pandemic with multiple critically ill patients, including front-line clinicians, hospital administrators, professional societies, and public health or government officials. The current Task Force included a total of 100 participants from nine countries, comprised of clinicians and experts from a wide variety of disciplines. Comprehensive literature searches were conducted to identify studies upon which evidence-based recommendations could be made. No studies of sufficient quality were identified. Therefore, the panel developed expert-opinion-based suggestions that are presented in this supplement using a modified Delphi process. The ultimate aim of the supplement is to expand the focus beyond the walls of ICUs to provide recommendations for the management of all critically ill or injured adults and children resulting from a pandemic or disaster wherever that care may be provided. Considerations for the management of critically ill patients include clinical priorities and logistics (supplies, evacuation, and triage) as well as the key enablers (systems planning, business continuity, legal framework, and ethical considerations) that facilitate the provision of this care. The supplement also aims to illustrate how the concepts of mass critical care are integrated across the spectrum of surge events from conventional through contingency to crisis standards of care.

Nutritional requirements of the critically ill patient.

PubMed

Chan, Daniel L

2004-02-01

The presence or development of malnutrition during critical illness has been unequivocally associated with increased morbidity and mortality in people. Recognition that malnutrition may similarly affect veterinary patients emphasizes the need to properly address the nutritional requirements of hospitalized dogs and cats. Because of a lack in veterinary studies evaluating the nutritional requirements of critically ill small animals, current recommendations for nutritional support of veterinary patients are based largely on sound clinical judgment and the best information available, including data from experimental animal models and human studies. This, however, should not discourage the veterinary practitioner from implementing nutritional support in critically ill patients. Similar to many supportive measures of critically ill patients, nutritional interventions can have a significant impact on patient morbidity and may even improve survival. The first step of nutritional support is to identify patients most likely to benefit from nutritional intervention. Careful assessment of the patient and appraisal of its nutritional needs provide the basis for a nutritional plan, which includes choosing the optimal route of nutritional support, determining the number of calories to provide, and determining the composition of the diet. Ultimately, the success of the nutritional management of critically ill dogs and cats will depend on close monitoring and frequent reassessment.

Sepsis Pathophysiology, Chronic Critical Illness, and Persistent Inflammation-Immunosuppression and Catabolism Syndrome.

To provide an appraisal of the evolving paradigms in the pathophysiology of sepsis and propose the evolution of a new phenotype of critically ill patients, its potential underlying mechanism, and its implications for the future of sepsis management and research. Literature search using PubMed, MEDLINE, EMBASE, and Google Scholar. Sepsis remains one of the most debilitating and expensive illnesses, and its prevalence is not declining. What is changing is our definition(s), its clinical course, and how we manage the septic patient. Once thought to be predominantly a syndrome of over exuberant inflammation, sepsis is now recognized as a syndrome of aberrant host protective immunity. Earlier recognition and compliance with treatment bundles has fortunately led to a decline in multiple organ failure and in-hospital mortality. Unfortunately, more and more sepsis patients, especially the aged, are suffering chronic critical illness, rarely fully recover, and often experience an indolent death. Patients with chronic critical illness often exhibit "a persistent inflammation-immunosuppression and catabolism syndrome," and it is proposed here that this state of persisting inflammation, immunosuppression and catabolism contributes to many of these adverse clinical outcomes. The underlying cause of inflammation-immunosuppression and catabolism syndrome is currently unknown, but there is increasing evidence that altered myelopoiesis, reduced effector T-cell function, and expansion of immature myeloid-derived suppressor cells are all contributory. Although newer therapeutic interventions are targeting the inflammatory, the immunosuppressive, and the protein catabolic responses individually, successful treatment of the septic patient with chronic critical illness and persistent inflammation-immunosuppression and catabolism syndrome may require a more complementary approach.

This article aims to introduce, compare and analyze the design and development of Critical Illness Insurance systems in different parts of China under different social and economic conditions, to explain their characteristics and similarities. It may provide references to other countries, especially developing countries, to solve the problem of high medical costs. According to the methods in Comparative Economics, 3 areas (Taicang in Jiangsu, Zhanjiang in Guangdong, Xunyi in Shanxi) which are in high, medium and low socio-economic condition respectively were chosen in China. Their critical illness insurance systems were analyzed in the study. Each system shares several common points, including coordinating urban and rural medical insurance fund, financing from the basic medical insurance surplus, and exploring payment reform and so on. But in the way of management, Taicang and Zhanjiang cooperate with commercial insurance agencies, but Xunyi chooses autonomous management by government. In Xunyi, multi-channel financing is relatively more dispersed, while funds of Taicang and Zhanjiang are mainly from the basic medical insurance surplus. The specific method of payment is different among these three areas. Because of the differences in economic development, population structure, and sources of funds, each area took their own mode on health policy orientation, financing, payment, coverage, and fund management to design their Critical Illness Insurance systems. This might provide references to other areas in China and other developing countries in the world.

Acute right ventricular dysfunction: real-time management with echocardiography.

PubMed

Krishnan, Sundar; Schmidt, Gregory A

2015-03-01

In critically ill patients, the right ventricle is susceptible to dysfunction due to increased afterload, decreased contractility, or alterations in preload. With the increased use of point-of-care ultrasonography and a decline in the use of pulmonary artery catheters, echocardiography can be the ideal tool for evaluation and to guide hemodynamic and respiratory therapy. We review the epidemiology of right ventricular failure in critically ill patients; echocardiographic parameters for evaluating the right ventricle; and the impact of mechanical ventilation, fluid therapy, and vasoactive infusions on the right ventricle. Finally, we summarize the principles of management in the context of right ventricular dysfunction and provide recommendations for echocardiography-guided management.

The evolution of pain management in the critically ill trauma patient: Emerging concepts from the global war on terrorism.

PubMed

Malchow, Randall J; Black, Ian H

2008-07-01

The evolution of military medical care to manage polytrauma, critically ill-wounded warriors from the greater war on terrorism has been accompanied by significant changes in the diagnosis, management, and modulation of acute and chronic trauma-related pain. A paradigm shift in pain management includes early treatment of pain at the point of injury and throughout the continuum of care with a combination of standard and novel therapeutic interventions. These concepts are important for all critical care providers because they translate to most critically ill patients, including those resulting from natural disasters. Previous authors have reported a high incidence of moderate to severe pain and poor analgesia in intensive care units associated with sleep disturbances, tachycardia, pulmonary complications, increased stress response with thromboembolic incidents, and immunosuppression, increased intensive care unit and hospital stays, and needless suffering. Although opioids have traditionally been the cornerstone of acute pain management, they have potential negative effects ranging from sedation, confusion, respiratory depression, nausea, ileus, constipation, tolerance, opioid-induced hyperalgesia as well as potential for immunosuppression. Alternatively, multimodal therapy is increasingly recognized as a critical pain management approach, especially when combined with early nutrition and ambulation, designed to improve functional recovery and decrease chronic pain conditions. Multimodal therapy encompasses a wide range of procedures and medications, including regional analgesia with continuous epidural or peripheral nerve block infusions, judicious opioids, acetaminophen, anti-inflammatory agents, anticonvulsants, ketamine, clonidine, mexiletine, antidepressants, and anxiolytics as options to treat or modulate pain at various sites of action. With a more aggressive acute pain management strategy, the military has decreased acute and chronic pain conditions, which may have application in the civilian sector as well.

Timing of the initiation of parenteral nutrition in critically ill children.

To review the current literature evaluating clinical outcomes of early and delayed parenteral nutrition initiation among critically ill children. Nutritional management remains an important aspect of care among the critically ill, with enteral nutrition generally preferred. However, inability to advance enteral feeds to caloric goals and contraindications to enteral nutrition often leads to reliance on parenteral nutrition. The timing of parenteral nutrition initiation is varied among critically ill children, and derives from an assessment of nutritional status, energy requirements, and physiologic differences between adults and children, including higher nutrient needs and lower body reserves. A recent randomized control study among critically ill children suggests improved clinical outcomes with avoiding initiation of parenteral nutrition on day 1 of admission to the pediatric ICU. Although there is no consensus on the optimal timing of parenteral nutrition initiation among critically ill children, recent literature does not support the immediate initiation of parenteral nutrition on pediatric ICU admission. A common theme in the reviewed literature highlights the importance of accurate assessment of nutritional status and energy expenditure in deciding when to initiate parenteral nutrition. As with all medical interventions, the initiation of parenteral nutrition should be considered in light of the known benefits of judiciously provided nutritional support with the known risks of artificial, parenteral feeding.

Purpose of Review To review the current literature evaluating clinical outcomes of early and delayed parenteral nutrition initiation among critically ill children. Recent Findings Nutritional management remains an important aspect of care among the critically ill, with enteral nutrition (EN) generally preferred. However, inability to advance enteral feeds to caloric goals and contraindications to EN often leads to reliance on parenteral nutrition (PN). The timing of PN initiation is varied among critically ill children, and derives from an assessment of nutritional status, energy requirements, and physiologic differences between adults and children, including higher nutrient needs and lower body reserves. A recent randomized control study among critically ill children suggests improved clinical outcomes with postponing initiation of PN to 1 week after admission to the pediatric intensive care unit (PICU). Summary Although there is no consensus on the optimal timing of PN initiation among critically ill children, recent literature does not support the immediate initiation of PN on PICU admission. A common theme in the reviewed literature highlights the importance of accurate assessment of nutritional status and energy expenditure in deciding when to initiate PN. As with all medical interventions, the initiation of PN should be considered in light of the known benefits of judiciously provided nutritional support with the known risks of artificial, parenteral feeding.

Decisions about optimal treatment for critically ill children are qualitatively different from those related to adults. Technological advances over the past several decades have resulted in myriad treatment options that leave many children chronically, critically ill. These children are often technology dependent. With new technologies and new patient populations comes the responsibility to understand how, when, and why these technologies are applied and when technology should not be used or should be withdrawn. Much has been written about ethical decision making in the care of chronically, critically ill adults and newborns. In this article, relevant factors about the care of children older than neonates are described: standards, decision makers, age of the child, and pain management. A case study is used as a mechanism to explore these issues. Dimensions of futility, discontinuing aggressive treatment, and a consideration of benefits and burdens are integrated throughout the discussion to inform nurse practitioner practice.

Propofol-Related Infusion Syndrome in Critically Ill Pediatric Patients: Coincidence, Association, or Causation?

PubMed Central

Timpe, Erin M.; Eichner, Samantha F.; Phelps, Stephanie J.

2006-01-01

Over the past two decades numerous reports have described the development of a propofol-related infusion syndrome (PRIS) in critically ill adult and pediatric patients who received continuous infusion propofol for anesthesia or sedation. The syndrome is generally characterized by progressive metabolic acidosis, hemodynamic instability and bradyarrhythmias that are refractory to aggressive pharmacological treatments. PRIS may occur with or without the presence of hepatomegaly, rhabdomyolysis or lipemia. To date, the medical literature contains accounts of 20 deaths in critically ill pediatric patients who developed features consistent with PRIS. These reports have generated considerable discussion and debate regarding the relationship, if any, between propofol and a constellation of clinical symptoms and features that have been attributed to its use in critically ill pediatric patients. This paper reviews the literature concerning PRIS, its clinical presentation, proposed mechanisms for the syndrome, and potential management should the syndrome occur. PMID:23118644

Animal models of critical illness are vital in biomedical research. They provide possibilities for the investigation of pathophysiological processes that may not otherwise be possible in humans. In order to be clinically applicable, the model should simulate the critical care situation realistically, including anaesthesia, monitoring, sampling, utilising appropriate personnel skill mix, and therapeutic interventions. There are limited data documenting the constitution of ideal technologically advanced large animal critical care practices and all the processes of the animal model. In this paper, we describe the procedure of animal preparation, anaesthesia induction and maintenance, physiologic monitoring, data capture, point-of-care technology, and animal aftercare that has been successfully used to study several novel ovine models of critical illness. The relevant investigations are on respiratory failure due to smoke inhalation, transfusion related acute lung injury, endotoxin-induced proteogenomic alterations, haemorrhagic shock, septic shock, brain death, cerebral microcirculation, and artificial heart studies. We have demonstrated the functionality of monitoring practices during anaesthesia required to provide a platform for undertaking systematic investigations in complex ovine models of critical illness.

Giving patients responsibility or fostering mutual response-ability: family physicians' constructions of effective chronic illness management.

PubMed

Thille, Patricia H; Russell, Grant M

2010-10-01

Current visions of family medicine and models of chronic illness management integrate evidence-based medicine with collaborative, patient-centered care, despite critiques that these constructs conflict with each other. With this potential conflict in mind, we applied a critical discursive psychology methodology to present discursive patterns articulated by 13 family physicians in Ontario, Canada, regarding care of patients living with multiple chronic illnesses. Physicians constructed competing versions of the terms "effective chronic illness management" and "patient involvement." One construction integrated individual responsibility for health with primacy of "evidence," resulting in a conceptualization consistent with paternalistic care. The second constructed effective care as involving active partnership of physician and patient, implying a need to foster the ability of both practitioners and patients to respond to complex challenges as they arose. The former pattern is inconsistent with visions of family medicine and chronic illness management, whereas the latter embodies it.

Capacity to provide critical care in resource-limited settings is poorly understood because of lack of data about resources available to manage critically ill patients. Our objective was to develop a survey to address this issue. We developed and piloted a cross-sectional self-administered survey in 9 resource-limited countries. The survey consisted of 8 domains; specific items within domains were modified from previously developed survey tools. We distributed the survey by e-mail to a convenience sample of health care providers responsible for providing care to critically ill patients. We assessed clinical sensibility and test-retest reliability. Nine of 15 health care providers responded to the survey on 2 separate occasions, separated by 2 to 4 weeks. Clinical sensibility was high (3.9-4.9/5 on assessment tool). Test-retest reliability for questions related to resource availability was acceptable (intraclass correlation coefficient, 0.94; 95% confidence interval, 0.75-0.99; mean (SD) of weighted κ values = 0.67 [0.19]). The mean (SD) time for survey completion survey was 21 (16) minutes. A reliable cross-sectional survey of available resources to manage critically ill patients can be feasibly administered to health care providers in resource-limited settings. The survey will inform future research focusing on access to critical care where it is poorly described but urgently needed. Copyright © 2016 Elsevier Inc. All rights reserved.

Physiological and management implications of obesity in critical illness.

PubMed

Shashaty, Michael G S; Stapleton, Renee D

2014-10-01

Obesity is highly prevalent in the United States and is becoming increasingly common worldwide. The anatomic and physiological changes that occur in obese individuals may have an impact across the spectrum of critical illness. Obese patients may be more susceptible to hypoxemia and hypercapnia. During mechanical ventilation, elevated end-expiratory pressures may be required to improve lung compliance and to prevent ventilation-perfusion mismatch due to distal airway collapse. Several studies have shown an increased risk of organ dysfunction such as the acute respiratory distress syndrome and acute kidney injury in obese patients. Predisposition to ventricular hypertrophy and increases in blood volume should be considered in fluid management decisions. Obese patients have accelerated muscle losses in critical illness, making nutrition essential, although the optimal predictive equation to estimate nutritional needs or formulation for obese patients is not well established. Many common intensive care unit medications are not well studied in obese patients, necessitating understanding of pharmacokinetic concepts and consultation with pharmacists. Obesity is associated with higher risk of deep venous thrombosis and catheter-associated bloodstream infections, likely related to greater average catheter dwell times. Logistical issues such as blood pressure cuff sizing, ultrasound assistance for procedures, diminished quality of some imaging modalities, and capabilities of hospital equipment such as beds and lifts are important considerations. Despite the physiological alterations and logistical challenges involved, it is not clear whether obesity has an effect on mortality or long-term outcomes from critical illness. Effects may vary by type of critical illness, obesity severity, and obesity-associated comorbidities.

Gastric residual volume in critically ill patients: a dead marker or still alive?

PubMed

Elke, Gunnar; Felbinger, Thomas W; Heyland, Daren K

2015-02-01

Early enteral nutrition (EN) is consistently recommended as first-line nutrition therapy in critically ill patients since it favorably alters outcome, providing both nutrition and nonnutrition benefits. However, critically ill patients receiving mechanical ventilation are at risk for regurgitation, pulmonary aspiration, and eventually ventilator-associated pneumonia (VAP). EN may increase these risks when gastrointestinal (GI) dysfunction is present. Gastric residual volume (GRV) is considered a surrogate parameter of GI dysfunction during the progression of enteral feeding in the early phase of critical illness and beyond. By monitoring GRV, clinicians may detect patients with delayed gastric emptying earlier and intervene with strategies that minimize or prevent VAP as one of the major risks of EN. The value of periodic GRV measurements with regard to risk reduction of VAP incidence has frequently been questioned in the past years. Increasing the GRV threshold before interrupting gastric feeding results in marginal increases in EN delivery. More recently, a large randomized clinical trial revealed that abandoning GRV monitoring did not negatively affect clinical outcomes (including VAP) in mechanically ventilated patients. The results have revived the discussion on the role of GRV monitoring in critically ill, mechanically ventilated patients receiving early EN. This review summarizes the most recent clinical evidence on the use of GRV monitoring in critically ill patients. Based on the clinical evidence, it discusses the pros and cons and further addresses whether GRV is a dead marker or still alive for the nutrition management of critically ill patients. © 2014 American Society for Parenteral and Enteral Nutrition.

Bench-to-bedside review: The gut as an endocrine organ in the critically ill

PubMed Central

2010-01-01

In health, hormones secreted from the gastrointestinal tract have an important role in regulating gastrointestinal motility, glucose metabolism and immune function. Recent studies in the critically ill have established that the secretion of a number of these hormones is abnormal, which probably contributes to disordered gastrointestinal and metabolic function. Furthermore, manipulation of endogenous secretion, physiological replacement and supra-physiological treatment (pharmacological dosing) of these hormones are likely to be novel therapeutic targets in this group. Fasting ghrelin concentrations are reduced in the early phase of critical illness, and exogenous ghrelin is a potential therapy that could be used to accelerate gastric emptying and/or stimulate appetite. Motilin agonists, such as erythromycin, are effective gastrokinetic drugs in the critically ill. Cholecystokinin and peptide YY concentrations are elevated in both the fasting and postprandial states, and are likely to contribute to slow gastric emptying. Accordingly, there is a rationale for the therapeutic use of their antagonists. So-called incretin therapies (glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide) warrant evaluation in the management of hyperglycaemia in the critically ill. Exogenous glucagon-like peptide-2 (or its analogues) may be a potential therapy because of its intestinotropic properties. PMID:20887636

Introduction Sepsis is a common, costly and morbid cause of critical illness in trauma and surgical patients. Ongoing advances in sepsis resuscitation and critical care support strategies have led to improved in-hospital mortality.

The short-term outcomes of patients with cystic fibrosis (CF) surviving critical illness were not examined systematically. To determine the factors associated with and variation in rates of routine home discharge among ICU-managed adult CF patients. Predictors of routine home discharge and its hospital-level variation were examined in ICU-managed adults with cystic fibrosis in Texas during 2004-2013. Older age, rural residence, and severity of illness decreased odds of routine home discharge, while hospitalization in facilities accredited as part of the Cystic Fibrosis Foundation Care Center Network nearly doubled the odds of routine home discharge. The median (interquartile) adjusted rate of routine home discharge was 62.0% (31.5-82.5). The identified determinants of routine home discharge can inform clinical decision-making, while the demonstrated wide variation in adjusted across-hospital rates of routine home discharge of ICU-managed adults with CF can provide benchmark data for future quality improvement efforts.

Little is known about how children and young people experience and manage the critical illness of a parent and a parent's admission to the intensive care unit (ICU). The aim of this study was to search and interpret the existing literature describing children's and young people's experiences of a parent's illness trajectory in the ICU. A qualitative meta-synthesis was conducted based on a systematic literature search of online databases. Four main themes were identified and synthesised to describe the integrated experiences of children and young people: (a) the parent-child bond, (b) the unfamiliar environment, (c) the impact of the illness and (d) the experience of being overseen as close family members. Experiencing a parent's critical illness and admittance to the ICU is overwhelming. The bond between the parent and child is exposed by the separation from the ill parent. To comprehend and manage the experience, children and young people seek information depending on their individual capacities. They express a need to be close to their ill parent and to be seen and approached as close members of the family. However, children experience being overseen in their needs for support during their parent's ICU illness with the risk of being left in loneliness, sadness and lack of understanding of the parent's illness. Children and young people as relatives need to be acknowledged as close members of the family, when facing the illness trajectory of a parent, who is admitted to the ICU. They need to be seen as close family members and to be approached in their needs for support in order to promote their well-being during a family illness crisis. Early supportive interventions tailored to include children of the intensive care patient are recommended. © 2018 John Wiley & Sons Ltd.

Collaborative Help in Chronic Disease Management: Supporting Individualized Problems

Huh, Jina; Ackerman, Mark S.

Coping with chronic illness disease is a long and lonely journey, because the burden of managing the illness on a daily basis is placed upon the patients themselves. In this paper, we present our findings for how diabetes patient support groups help one another find individualized strategies for managing diabetes. Through field observations of face-to-face diabetes support groups, content analysis of an online diabetes community, and interviews, we found several help interactions that are critical in helping patients in finding individualized solutions. Those are: (1) patients operationalize their experiences to easily contextualize and share executable strategies; (2) operationalization has to be done within the larger context of sharing illness trajectories; and (3) the support groups develop common understanding towards diabetes management. We further discuss how our findings translate into design implications for supporting chronic illness patients in online community settings. PMID:25360442

The present qualitative study aimed to explore the factors influencing nutritional recovery in patients after critical illness and to develop a model of care to improve current management of nutrition for this patient group. Patients were recruited into the study on discharge from a general intensive care unit (ICU) of a large teaching hospital in central Scotland. Semi-structured interviews were carried out after discharge from the ICU, weekly for the duration of their ward stay, and at 3 months post ICU discharge. Observations of ward practice were undertaken thrice weekly for the duration of the ward stay. Seventeen patients were recruited into the study and, using a grounded theory approach, 'inter-related system breakdowns during the nutritional recovery process' emerged as the overarching core category that influenced patients' experiences of eating after critical illness. This encompassed the categories, 'experiencing a dysfunctional body', 'experiencing socio-cultural changes in relation to eating' and 'encountering nutritional care delivery failures'. The findings from the present study provide a unique contribution to knowledge by offering important insights into patients' experiences of eating after critical illness. The study has identified numerous nutritional problems and raises questions about the efficacy of current nutritional management in this patient group. Adopting a more individualised approach to nutritional care could ameliorate the nutritional issues experienced by post ICU patients. This will be evaluated in future work. © 2014 The British Dietetic Association Ltd.

Approximately 5 to 10% of critically ill patients transition from acute critical illness to a state of persistent and in some cases chronic critical illness. These patients have unique and complex needs that require a change in the clinical management plan and overall goals of care to a focus on rehabilitation, symptom relief, discharge planning, and in some cases, end-of-life care. However, existing indicators and measures of care quality, and tools such as checklists, that foster implementation of best practices, may not be sufficiently inclusive in terms of actionable processes of care relevant to these patients. Therefore, the aim of this systematic review is to identify the processes of care, performance measures, quality indicators, and outcomes including reports of patient/family experience described in the current evidence base relevant to patients with persistent or chronic critical illness and their family members. Two authors will independently search from inception to November 2016: MEDLINE, Embase, CINAHL, Web of Science, the Cochrane Library, PROSPERO, the Joanna Briggs Institute and the International Clinical Trials Registry Platform. We will include all study designs except case series/reports of <10 patients describing their study population (aged 18 years and older) using terms such as persistent critical illness, chronic critical illness, and prolonged mechanical ventilation. Two authors will independently perform data extraction and complete risk of bias assessment. Our primary outcome is to determine actionable processes of care and interventions deemed relevant to patients experiencing persistent or chronic critical illness and their family members. Secondary outcomes include (1) performance measures and quality indicators considered relevant to our population of interest and (2) themes related to patient and family experience. We will use our systematic review findings, with data from patient, family member and clinician interviews, and a subsequent consensus building process to inform the development of quality metrics and tools to measure processes of care, outcomes and experience for patients experiencing persistent or chronic critical illness and their family members.

Sepsis is a common, costly and morbid cause of critical illness in trauma and surgical patients. Ongoing advances in sepsis resuscitation and critical care support strategies have led to improved in-hospital mortality.

Chronically critically ill patients often have high costs of care and poor outcomes and thus might benefit from a disease management program. To evaluate how adding a disease management program to the usual care system affects outcomes after discharge from the hospital (mortality, health-related quality of life, resource use) in chronically critically ill patients. In a prospective experimental design, 335 intensive care patients who received more than 3 days of mechanical ventilation at a university medical center were recruited. For 8 weeks after discharge, advanced practice nurses provided an intervention that focused on case management and interdisciplinary communication to patients in the experimental group. A total of 74.0% of the patients survived and completed the study. Significant predictors of death were age (P = .001), duration of mechanical ventilation (P = .001), and history of diabetes (P = .04). The disease management program did not have a significant impact on health-related quality of life; however, a greater percentage of patients in the experimental group than in the control group had "improved" physical health-related quality of life at the end of the intervention period (P = .02). The only significant effect of the intervention was a reduction in the number of days of hospital readmission and thus a reduction in charges associated with readmission. The intervention was not associated with significant changes in any outcomes other than duration of readmission, but the supportive care coordination program could be provided without increasing overall charges.

Impact of a multifaceted educational intervention including serious games to improve the management of invasive candidiasis in critically ill patients.

Infections caused by Candida species are common in critically ill patients and contribute to significant morbidity and mortality. The EPICO Project (Epico 1 and Epico 2.0 studies) recently used a Delphi approach to elaborate guidelines for the diagnosis and treatment of this condition in critically ill adult patients. We aimed to evaluate the impact of a multifaceted educational intervention based on the Epico 1 and Epico 2.0 recommendations. Specialists anonymously responded to two online surveys before and after a multifaceted educational intervention consisting of 60-min educational sessions, the distribution of slide kits and pocket guides with the recommendations, and an interactive virtual case presented at a teleconference and available for online consultation. A total of 74 Spanish hospitals. Specialists of the Intensive Care Units in the participating hospitals. Specialist knowledge and reported practices evaluated using a survey. The McNemar test was used to compare the responses in the pre- and post-intervention surveys. A total of 255 and 248 specialists completed both surveys, in both periods, respectively. The pre-intervention surveys showed many specialists to be unaware of the best approach for managing invasive candidiasis. After both educational interventions, specialist knowledge and reported practices were found to be more in line with nearly all the recommendations of the Epico 1 and Epico 2.0 guidelines, except as regards de-escalation from echinocandins to fluconazole in Candida glabrata infections (p=0.055), and the duration of antifungal treatment in both candidemia and peritoneal candidiasis. This multifaceted educational intervention based on the Epico Project recommendations improved specialist knowledge of the management of invasive candidiasis in critically ill patients.

Critically ill or injured children require prompt identification, rapid referral and quality emergency management. We undertook a study to evaluate the care pathway of critically ill or injured children to identify preventable failures in the care provided. A year-long cohort study of critically ill and injured children was performed in Cape Town, South Africa, from first presentation to healthcare services until paediatric intensive care unit (PICU) admission or emergency department death, using expert panel review of medical records and caregiver interview. Main outcomes were expert assessment of overall quality of care; avoidability of severity of illness and PICU admission or death and the identification of modifiable factors. The study enrolled 282 children, 252 emergency PICU admissions, and 30 deaths. Global quality of care was graded good in 10% of cases, with half having at least one major impact modifiable factor. Key modifiable factors related to access to care and identification of the critically ill, assessment of severity, inadequate resuscitation, and delays in decision making and referral. Children were transferred with median time from first presentation to PICU admission of 12.3 hours. There was potentially avoidable severity of illness in 185 (74%) of children, and death prior to PICU admission was avoidable in 17/30 (56.7%) of children. The study presents a novel methodology, examining quality of care across an entire system, and highlighting the complexity of the pathway and the modifiable events amenable to interventions, that could reduce mortality and morbidity, and optimize utilization of scarce critical care resources; as well as demonstrating the importance of continuity and quality of care.

Interpatient Variability in Dexmedetomidine Response: A Survey of the Literature

Fifty-five thousand patients are cared for in the intensive care unit (ICU) daily with sedation utilized to reduce anxiety and agitation while optimizing comfort. The Society of Critical Care Medicine (SCCM) released updated guidelines for management of pain, agitation, and delirium in the ICU and recommended nonbenzodiazepines, such as dexmedetomidine and propofol, as first line sedation agents. Dexmedetomidine, an alpha-2 agonist, offers many benefits yet its use is mired by the inability to consistently achieve sedation goals. Three hypotheses including patient traits/characteristics, pharmacokinetics in critically ill patients, and clinically relevant genetic polymorphisms that could affect dexmedetomidine response are presented. Studies in patient traits have yielded conflicting results regarding the role of race yet suggest that dexmedetomidine may produce more consistent results in less critically ill patients and with home antidepressant use. Pharmacokinetics of critically ill patients are reported as similar to healthy individuals yet wide, unexplained interpatient variability in dexmedetomidine serum levels exist. Genetic polymorphisms in both metabolism and receptor response have been evaluated in few studies, and the results remain inconclusive. To fully understand the role of dexmedetomidine, it is vital to further evaluate what prompts such marked interpatient variability in critically ill patients. PMID:24558330

How Much and What Type of Protein Should a Critically Ill Patient Receive?

Protein loss, manifested as loss of muscle mass, is observed universally in all critically ill patients. Depletion of muscle mass is associated with impaired function and poor outcomes. In extreme cases, protein malnutrition is manifested by respiratory failure, lack of wound healing, and immune dysfunction. Protecting muscle loss focused initially on meeting energy requirements. The assumption was that protein was being used (through oxidation) as an energy source. In healthy individuals, small amounts of glucose (approximately 400 calories) protect muscle loss and decrease amino acid oxidation (protein-sparing effect of glucose). Despite expectations of the benefits, the high provision of energy (above basal energy requirements) through the delivery of nonprotein calories has failed to demonstrate a clear benefit at curtailing protein loss. The protein-sparing effect of glucose is not clearly observed during illness. Increasing protein delivery beyond the normal nutrition requirements (0.8 g/k/d) has been investigated as an alternative solution. Over a dozen observational studies in critically ill patients suggest that higher protein delivery is beneficial at protecting muscle mass and associated with improved outcomes (decrease in mortality). Not surprisingly, new Society of Critical Care Medicine/American Society for Parenteral and Enteral Nutrition guidelines and expert recommendations suggest higher protein delivery (>1.2 g/kg/d) for critically ill patients. This article provides an introduction to the concepts that delineate the basic principles of modern medical nutrition therapy as it relates to the goal of achieving an optimal management of protein metabolism during critical care illness, highlighting successes achieved so far but also placing significant challenges limiting our success in perspective.

Clinical protocols may decrease unnecessary variation in care and improve compliance with desirable therapies. We evaluated whether highly protocolized ICUs have superior patient outcomes compared with less highly protocolized ICUs. Observational study in which participating ICUs completed a general assessment and enrolled new patients 1 day each week. A total of 6,179 critically ill patients. Fifty-nine ICUs in the United States Critical Illness and Injury Trials Group Critical Illness Outcomes Study. None. The primary exposure was the number of ICU protocols; the primary outcome was hospital mortality. A total of 5,809 participants were followed prospectively, and 5,454 patients in 57 ICUs had complete outcome data. The median number of protocols per ICU was 19 (interquartile range, 15-21.5). In single-variable analyses, there were no differences in ICU and hospital mortality, length of stay, use of mechanical ventilation, vasopressors, or continuous sedation among individuals in ICUs with a high versus low number of protocols. The lack of association was confirmed in adjusted multivariable analysis (p = 0.70). Protocol compliance with two ventilator management protocols was moderate and did not differ between ICUs with high versus low numbers of protocols for lung protective ventilation in acute respiratory distress syndrome (47% vs 52%; p = 0.28) and for spontaneous breathing trials (55% vs 51%; p = 0.27). Clinical protocols are highly prevalent in U.S. ICUs. The presence of a greater number of protocols was not associated with protocol compliance or patient mortality.

Physician staffing pattern in intensive care units: Have we cracked the code?

PubMed Central

Juneja, Deven; Nasa, Prashant; Singh, Omender

2012-01-01

Intensive care is slowly being recognized as a separate medical specialization. Physicians, called intensivists, are being specially trained to manage intensive care units (ICUs) and provide focused, high quality care to critically ill patients. However, these ICUs were traditionally managed by primary physicians who used to admit patients in ICUs under their own care. The presence of specially trained intensivists in these ICUs has started a “turf” war. In spite of the availability of overwhelming evidence that intensivists-based ICUs can provide better patient care leading to improved outcome, there is hesitancy among hospital administrators and other policy makers towards adopting such a model. Major critical care societies and workgroups have recommended intensivists-based ICU models to care for critically ill patients, but even in developed countries, on-site intensivist coverage is lacking in a great majority of hospitals. Lack of funds and unavailability of skilled intensivists are commonly cited as the main reasons for not implementing intensivist-led ICU care in most of the ICUs. To provide optimal, comprehensive and skilled care to this severely ill patient population, it is imperative that a multi-disciplinary team approach must be adopted with intensivists as in-charge. Even though ICU organization and staffing may be determined by hospital policies and other local factors, all efforts must be made to attain the goal of having round-the-clock onsite intensivist coverage to ensure continuity of specialized care for all critically ill patients.

We report an ethnographic analysis of a psycho-education and peer-support program for school-aged children of parents with mental illnesses. We conducted a critical discourse analysis of the program manual and observed group interactions to understand whether children shared program goals predetermined by adults, and how, or if, the intervention was responsive to their needs. Children were expected to learn mental illness information because "knowledge is power," and to express difficult feelings about being a child of a mentally ill parent that was risky. Participants used humor to manage group expectations, revealing how they made sense of their parents' problems, as well as their own. Suggestions are made for determining good mental health literacy based on children's preferences for explaining circumstances in ways they find relevant, and for supporting children's competencies to manage relationships that are important to them. © The Author(s) 2014.

Acute diarrheal illness during deployment causes significant morbidity and loss of duty days. Effective and timely treatment is needed to reduce individual, unit, and health system performance impacts. This critical appraisal of the literature, as part of the development of expert consensus guidelines, asked several key questions related to self-care and healthcare-seeking behavior, antibiotics for self-treatment of travelers' diarrhea, what antibiotics/regimens should be considered for treatment of acute watery diarrhea and febrile diarrhea and/or dysentery, and when and what laboratory diagnostics should be used to support management of deployment-related travelers' diarrhea. Studies of acute diarrhea management in military and other travelers were assessed for relevance and quality. On the basis of this critical appraisal, guideline recommendations were developed and graded by the Expert Panel using good standards in clinical guideline development methodology. New definitions for defining the severity of diarrhea during deployment were established. A total of 13 graded recommendations on the topics of prophylaxis, therapy and diagnosis, and follow-up were developed. In addition, four non-graded consensus-based statements were adopted. Successful management of acute diarrheal illness during deployment requires action at the provider, population, and commander levels. Strong evidence supports that single-dose antimicrobial therapy is effective in most cases of moderate to severe acute diarrheal illness during deployment. Further studies are needed to address gaps in available knowledge regarding optimal therapies for treatment, prevention, and laboratory testing of acute diarrheal illness.

Alcohol-Use Disorders in the Critically Ill Patient

PubMed Central

Jones, Drew G.; Sessler, Curtis N.; Zilberberg, Marya D.; Weaver, Michael F.

2010-01-01

Alcohol abuse and dependence, referred to as alcohol-use disorders (AUDs), affect 76.3 million people worldwide and account for 1.8 million deaths per year. AUDs affect 18.3 million Americans (7.3% of the population), and up to 40% of hospitalized patients have AUDs. This review discusses the development and progression of critical illness in patients with AUDs. In contrast to acute intoxication, AUDs have been linked to increased severity of illness in a number of studies. In particular, surgical patients with AUDs experience higher rates of postoperative hemorrhage, cardiac complications, sepsis, and need for repeat surgery. Outcomes from trauma are worse for patients with chronic alcohol abuse, whereas burn patients who are acutely intoxicated may not have worse outcomes. AUDs are linked to not only a higher likelihood of community-acquired pneumonia and sepsis but also a higher severity of illness and higher rates of nosocomial pneumonia and sepsis. The management of sedation in patients with AUDs may be particularly challenging because of the increased need for sedatives and opioids and the difficulty in diagnosing withdrawal syndrome. The health-care provider also must be watchful for the development of dangerous agitation and violence, as these problems are not uncommonly seen in hospital ICUs. Despite studies showing that up to 40% of hospitalized patients have AUDs, relatively few guidelines exist on the specific management of the critically ill patient with AUDs. AUDs are underdiagnosed, and a first step to improving patient outcomes may lie in systematically and accurately identifying AUDs. PMID:20923804

Music is an ideal intervention to reduce anxiety and promote relaxation in critically ill patients receiving mechanical ventilatory support. This article reviews the basis for a music listening intervention and describes two case examples with patients utilizing a music listening intervention to illustrate the implementation and use of the music listening protocol in this dynamic environment. The case examples illustrate the importance and necessity of engaging a music therapist in not only assessing the music preferences of patients, but also for implementing a music listening protocol to manage the varied and challenging needs of patients in the critical care setting. Additionally, the case examples presented in this paper demonstrate the wide array of music patients prefer and how the ease of a music listening protocol allows mechanically ventilated patients to engage in managing their own anxiety during this distressful experience.

2013-08-01

Plasmapheresis can benefit a variety of critically ill patients. A woman with diabetic ketoacidosis and severe hypertriglyceridemia was treated with plasmapheresis when conventional treatments did not markedly reduce her triglyceridemia. The patient was admitted to a medical intensive care unit because of diabetic ketoacidosis with severe lipemia. The lipemia-associated interference in laboratory studies made treatment of electrolyte abnormalities extremely difficult. The hypertriglyceridemia was initially treated with insulin, antilipidemic medications, and heparin, but the levels of triglycerides remained elevated, delaying results of needed laboratory studies for hours. After plasmapheresis, the serum level of triglycerides decreased by 77% in less than 24 hours. Severe lipemia interferes with photometric laboratory studies, yielding an underestimation of serum levels of electrolytes. Plasmapheresis is safe, rapid, and effective for emergent management of severe hypertriglyceridemia in critically ill patients. The impact of the procedure on critical care nursing is growing as nurses become involved in the treatment and follow-up care of patients who have plasmapheresis.

Acute cholecystitis is a common diagnosis. However, the heterogeneity of presentation makes it difficult to standardize management. Although surgery is the mainstay of treatment, critically ill patients have been managed via percutaneous cholecystostomy. However, the role of percutaneous cholecystostomy in the management of such patients has not been clearly established. This systematic review will compare the outcomes of critically ill patients with acute cholecystitis managed with percutaneous cholecystostomy to those of similar patients managed with cholecystectomy. Systematic searches will be conducted across relevant health databases including the Cochrane Library, Cumulative Index of Nursing and Allied Health Literature (CINAHL), MEDLINE, Embase, and Scopus using the following keywords: (acute cholecystitis OR severe cholecystitis OR cholecystitis) AND (cholecystectomy OR laparoscopic cholecystectomy OR open cholecystectomy) AND (Cholecystostomy OR percutaneous cholecystectomy OR gallbladder drain OR gallbladder tube OR transhepatic gallbladder drain OR transhepatic gallbladder tube OR cholecystostomy tube). The reference lists of eligible articles will be hand searched. Articles from 2000-2014 will be identified using the key terms "acute cholecystitis, cholecystectomy, and percutaneous cholecystostomy". Studies including both interventions will be included. Relevant data will be extracted from eligible studies using a specially designed data extraction sheet. The Newcastle-Ottawa scale will be used to assess the quality of non-randomized studies. Central tendencies will be reported in terms of means and standard deviations where necessary, and risk ratios will be calculated where possible. All calculations will be performed with a 95 % confidence interval. Furthermore, the Fisher's exact test will be used for the calculation of significance, which will be set at p < 0.05. Pooled estimates will be presented after consideration of both clinical and methodological heterogeneity of included studies. Both interventions would be compared with regard to in-hospital mortality, 30-day mortality, procedure-dependent complications, re-intervention, length of intensive care unit (ICU) stay, length of hospital stay, re-admission, and cost of treatment. The review will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. This systematic review aims at identifying and evaluating the clinical value of percutaneous cholecystostomy in the management of critically ill patients with acute cholecystitis.

Primary sclerosing cholangitis (PSC) is a rare idiopathic condition with immunopathogenic mechanisms where there is chronic progressive destruction of the biliary tree. Secondary sclerosing cholangitis (SSC) is clinically comparable to PSC, but is caused by specific processes which directly damage the biliary tree; examples include recurrent pancreatitis, bile duct malignancy, congenital bile duct abnormalities. A new cause of SSC has been described during or following significant critical illness associated with severe respiratory insufficiency, vasopressor requirement, shock and sepsis. This condition rapidly progresses to cirrhosis, frequently requiring liver transplantation for definitive management. Copyright: © 2018 Permanyer.

Significant predictors of death were age (P = .001), duration of mechanical ventilation (P = .001), and history of diabetes (P = .04). The disease management program did not have a significant impact on health-related quality of life; however, a greater percentage of patients in the experimental group than in the control group had “improved” physical health-related quality of life at the end of the intervention period (P = .02). The only significant effect of the intervention was a reduction in the number of days of hospital readmission and thus a reduction in charges associated with readmission. Conclusion The intervention was not associated with significant changes in any outcomes other than duration of readmission, but the supportive care coordination program could be provided without increasing overall charges.

To assess whether serum concentration of endothelial cell-specific molecule-1 (Endocan) at ICU admission is associated with the use of ICU resources and outcomes in critically ill hematology patients. Prospective multicenter cohort study. Seventeen ICUs in France and Belgium. Seven hundred forty-four consecutive critically ill hematology patients; 72 critically ill septic patients without hematologic malignancy; 276 healthy subjects. None. Median total endocan concentrations were 4.46 (2.7-7.8) ng/mL. Endocan concentrations were higher in patients who had received chemotherapy before ICU admission (4.7 [2.8-8.1] ng/mL vs. 3.7 [2.5-6.3] ng/mL [p = 0.002]). In patients with acute respiratory failure, endocan levels were increased in patients with drug-induced pulmonary toxicity compared with other etiologies (p = 0.038). Total endocan levels higher than 4.46 ng/mL were associated with a higher cumulative probability of renal replacement therapy requirement (p = 0.006), a higher requirement of mechanical ventilation (p = 0.01) and a higher requirement of vasopressors throughout ICU stay (p < 0.0001). By multivariate analysis, total endocan levels at admission were independently associated with ICU mortality (odds ratios, 1.39; 95% CI, 1.06-1.83; p = 0.018). The predictive value of endocan peptide fragments of 14 kDa in terms of mortality and life-sustaining therapies requirement was inferior to that of total endocan. Endocan levels were higher in critically ill hematology patients compared with healthy subjects (p < 0.0001) but lower than endocan values in critically ill septic patients without hematologic malignancy (p = 0.005) CONCLUSIONS:: Serum concentrations of endocan at admission are associated with the use of ICU resources and mortality in critically ill hematology patients. Studies to risk-stratify patients in the emergency department or in the hematology wards based on endocan concentrations to identify those likely to benefit from early ICU management are warranted.

Updated knowledge of the palliative care (PC) literature is needed to maintain competency and best address the PC needs of hospitalized patients. We critiqued the recent PC literature with the highest potential to impact hospital practice. We reviewed articles published between January 2016 and December 2016, which were identified through a handsearch of leading journals and a MEDLINE search. The final 9 articles selected were determined by consensus based on scientific rigor, relevance to hospital medicine, and impact on practice. Key findings include the following: scheduled antipsychotics were inferior to a placebo for nonterminal delirium; a low-dose morphine was superior to a weak opioid for moderate cancer pain; methadone as a coanalgesic improved high-intensity cancer pain; many hospitalized patients on comfort care still receive antimicrobials; video decision aids improved the rates of advance care planning (ACP) and hospice use and decreased costs; standardized, PC-led intervention did not improve psychological outcomes in families of patients with a chronic critical illness; caregivers of patients surviving a prolonged critical illness experienced high and persistent rates of depression; people with non-normative sexuality or gender faced additional stressors with partner loss; and physician trainees experienced significant moral distress with futile treatments. Recent research provides important guidance for clinicians caring for hospitalized patients with serious illnesses, including symptom management, ACP, moral distress, and outcomes of critical illness. © 2017 Society of Hospital Medicine

The assessment of sleep quality in critically ill patients is a relevant factor of high-quality care. Despite the fact that sleep disturbances and insufficient sleep management contain an increased risk of severe morbidity for these patients, a translated and applicable instrument to evaluate sleep is not available for German-speaking intensive care settings. This study aimed to translate the Richards Campbell Sleep Questionnaire (RCSQ), a simple and validated instrument eligible for measuring sleep quality in critically ill patients, and subsequently to evaluate the internal consistency of the German version of the RCSQ. Furthermore, it also aimed to inquire into the perception of sleep in a sample of critically ill patients. The RCSQ was translated following established methodological standards. Data were collected cross-sectionally in a sample of 51 patients at 3 intensive care units at a university hospital in Germany. The German version of the RCSQ showed an overall internal consistency (Cronbach's alpha) of 0·88. The mean of the RSCQ in the sample was 47·00 (SD ± 27·57). Depth of sleep was rated the lowest and falling asleep again the highest of the RCSQ sleep items. The study demonstrated very good internal consistency of the German version of the RCSQ, allowing for its application in practice and research in German-speaking countries. Quality of sleep perception was generally low in this sample, emphasizing the need for enhanced care concepts regarding the sleep management of critically ill patients. Relevance to clinical practice Assessment of self-perception of sleep is crucial in order to plan an individually tailored care process. © 2017 British Association of Critical Care Nurses.

The 2009 influenza A (H1N1) pandemic caused surges of patients in intensive care units (ICUs) in resource-limited settings. Several Ministries of Health requested clinical management guidance from the World Health Organization (WHO), which had not previously developed guidance regarding critically ill patients. To assess the acceptability and impact on knowledge of a short course about the management of critically ill patients with acute respiratory infections complicated by sepsis or acute respiratory distress syndrome delivered to clinicians in resource-limited ICUs. Over four years (2009-2013), WHO led the development, piloting, implementation, and preliminary evaluation of a three-day course that emphasized patient management based on evidence-based guidelines and used interactive adult-learner teaching methodology. International content experts (n=35) and instructional designers contributed to development. We assessed participants' satisfaction and content knowledge before and after the course. The course was piloted among clinicians in Trinidad and Tobago (n=29), Indonesia (n=38), and Vietnam (n=86); feedback from these courses contributed to the final version. In 2013, inaugural national courses were delivered in Tajikistan (n=28), Uzbekistan (n=39), and Azerbaijan (n=30). Participants rated the course highly and demonstrated increased immediate content knowledge after (vs. before) course completion (p<0.001). We found that it was feasible to create and deliver a focused critical care short course to clinicians in low- and middle-income countries. Collaboration between WHO, clinical experts, instructional designers, Ministries of Health, and local clinician-leaders facilitated course delivery. Future work should assess its impact on longer-term knowledge retention and on processes and outcomes of care. This article is protected by copyright. All rights reserved.

To describe a portable life support device for transportation of pre-hospital patients with critical illness. The characteristics and requirements for urgent management during transportation of critically ill patients to a hospital were analyzed. With adoption of the original equipment, with the aid of staple of the art soft ware, the overall structure, its installation, fixation, freedom from interference, operational function were studied, and the whole system of life support and resuscitation was designed. The system was composed by different modules, including mechanical ventilation, transfusion, aspiration, critical care, oxygen supply and power supply parts. The system could be fastened quickly to a stretcher to form portable intensive care unit (ICU), and it could be carried by different size vehicles to provide nonstop treatment by using power supply of the vehicle, thus raising the efficiency of urgent care. With characteristics of its small size, lightweight and portable, the device is particularly suitable for narrow space and extreme environment.

The purpose of this study was to compare the effects of a low-technology environment of care and a nurse case management case delivery system (special care unit, SCU) with the traditional high-technology environment (ICU) and primary nursing care delivery system on the patient outcomes of length of stay, mortality, readmission, complications, satisfaction, and cost. A sample of 220 chronically critically ill patients were randomly assigned to either the SCU (n = 145) or the ICU (n = 75). Few significant differences were found between the two groups in length of stay, mortality, or complications. However, the findings showed significant cost savings in the SCU group in the charges accrued during the study period and in the charges and costs to produce a survivor. The average total cost of delivering care was $5,000 less per patient in the SCU than in the traditional ICU. In addition, the cost to produce a survivor was $19,000 less in the SCU. Results from this 4-year clinical trial demonstrate that nurse case managers in a SCU setting can produce patient outcomes equal to or better than those in the traditional ICU care environment for long-term critically ill patients.

Critically ill patients are at high risk of morbidity and mortality caused by venous thromboembolism (VTE). In addition to premorbid predisposing conditions, critically ill patients may be exposed to prolonged immobility, invasive intravascular catheters and frequent operative procedures, and further may have contraindications to pharmaceutical prophylactic measures designed to attenuate VTE risk. There are limited data describing current VTE prophylaxis regimens in Australia and New Zealand. To document current Australian and New Zealand management of VTE prophylaxis in a large mixed cohort of critically ill patients. Prospective, multicentre point prevalence survey endorsed by the Australian and New Zealand Intensive Care Society Clinical Trials Group (ANZICS CTG). 30 public hospital ICUs in Australia and New Zealand surveyed on Wednesday 9 May 2007. For all patients in each ICU on the study day, demographic data, admission diagnosis and information on VTE prophylaxis were prospectively collected. 502 patients were included in the survey, and 431 of these (86%) received VTE prophylaxis. Of these, 64% (276/431) received pharmacological prophylaxis and 80% (345/431) received mechanical prophylaxis, with 44% (190/431) receiving both. Of those receiving pharmacological prophylaxis, unfractionated heparin was used in 74%, and enoxaparin (low molecular weight heparin) in 23%. Contraindications to pharmacological prophylaxis were reported in 122 patients. Overall, pharmacological prophylaxis was administered to 87% of potentially suitable patients. We observed a high prevalence of VTE prophylaxis, with many critically ill patients receiving two or more modalities of prophylaxis. These results show that the potential risk of VTE in critically ill patients is recognised in Australia and New Zealand, and strategies to mitigate this serious complication are widely implemented.

Objective Clinical protocols may decrease unnecessary variation in care and improve compliance with desirable therapies. We evaluated whether highly protocolized intensive care units have superior patient outcomes compared with less highly protocolized intensive care units. Design Observational study in which participating intensive care units completed a general assessment and enrolled new patients one day each week. Setting and Patients 6179 critically ill patients across 59 intensive care units in the United States Critical Illness and Injury Trials Group Critical Illness Outcomes Study Interventions: None Measurements and Main Results The primary exposure was the number of intensive care unit protocols; the primary outcome was hospital mortality. 5809 participants were followed prospectively and 5454 patients in 57 intensive care units had complete outcome data. The median number of protocols per intensive care unit was 19 (IQR 15 to 21.5). In single variable analyses, there were no differences in intensive care unit and hospital mortality, length of stay, use of mechanical ventilation, vasopressors, or continuous sedation among individuals in intensive care units with a high vs. low number of protocols. The lack of association was confirmed in adjusted multivariable analysis (p=0.70). Protocol compliance with two ventilator management protocols was moderate and did not differ between intensive care units with high vs. low numbers of protocols for lung protective ventilation in ARDS (47% vs. 52%; p=0.28) and for spontaneous breathing trials (55% vs. 51%; p=0.27). Conclusions Clinical protocols are highly prevalent in United States intensive care units. The presence of a greater number of protocols was not associated with protocol compliance or patient mortality. PMID:26110488

Beta-lactams are at the cornerstone of therapy in critical care settings, but their clinical efficacy is challenged by the rise in bacterial resistance. Infections with multi-drug resistant organisms are frequent in intensive care units, posing significant therapeutic challenges. The problem is compounded by a dearth in the development of new antibiotics. In addition, critically-ill patients have unique physiologic characteristics that alter the drugs pharmacokinetics and pharmacodynamics. Areas covered: The prolonged infusion of antibiotics (extended infusion [EI] and continuous infusion [CI]) has been the focus of research in the last decade. As beta-lactams have time-dependent killing characteristics that are altered in critically-ill patients, prolonged infusion is an attractive approach to maximize their drug delivery and efficacy. Several studies have compared traditional dosing to EI/CI of beta-lactams with regard to clinical efficacy. Clinical data are primarily composed of retrospective studies and some randomized controlled trials. Several reports show promising results. Expert commentary: Reviewing the currently available evidence, we conclude that EI/CI is probably beneficial in the treatment of critically-ill patients in whom an organism has been identified, particularly those with respiratory infections. Further studies are needed to evaluate the efficacy of EI/CI in the management of infections with resistant organisms.

Glycemic variability is an independent predictor of mortality in critically ill patients. The objective of this study was to compare two intravenous insulin protocols in critically ill patients regarding the glycemic variability. This was a retrospective observational study performed by reviewing clinical records of patients from a Critical Care Unit for 4 consecutive months. First, a simpler Scale-Based Intravenous Insulin Protocol (SBIIP) was reviewed and later it was compared for the same months of the following year with a Sliding Scale-Based Intravenous Insulin Protocol (SSBIIP). All adult patients admitted to the unit during the referred months were included. Patients in whom the protocol was not adequately followed were excluded. A total of 557 patients were reviewed, of whom they had needed intravenous insulin 73 in the first group and 52 in the second group. Four and two patients were excluded in each group respectively. Glycemic variability for both day 1 (DS1) and total stay (DST) was lower in SSBIIP patients compared to SBIIP patients: SD1 34.88 vs 18.16 and SDT 36.45 vs 23.65 (P<.001). A glycemic management protocol in critically ill patients based on sliding scales decreases glycemic variability. Copyright © 2017 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

Despite a paucity of data regarding both the incidence of ocular candidiasis and the utility of ophthalmic examination in critically ill patients, routine ophthalmic examination is recommended for critically ill patients with candidaemia. The objectives were to estimate the incidence of ocular candidiasis and evaluate whether ophthalmic examination influenced subsequent management of these patients. We conducted a ten-year retrospective observational study. Data were extracted for all ICU patients who were blood culture positive for fungal infection. Risk factors for candidaemia and eye involvement were quantified and details regarding ophthalmic examination were reviewed. Candida species were cultured in 93 patients. Risk factors for ocular candidiasis were present in 57% of patients. Forty-one percent of patients died prior to ophthalmology examination and 2% of patients were discharged before candidaemia was identified. During examination, signs of ocular candidiasis were only present in one (2.9%) patient, who had a risk factor for ocular candidiasis. Based on these findings, the duration of antifungal treatment for this patient was increased. Ocular candidiasis occurs rarely in critically ill patients with candidaemia, but because treatment regimens may be altered when diagnosed, routine ophthalmic examination is still indicated.

Health Activism Targeting Corporations: A Critical Health Communication Perspective.

Zoller, Heather M

2017-02-01

Health activists and health social movements have transformed medical treatment, promoted public health policies, and extended civil rights for people with illness and disability. This essay explores health activism that targets corporate-generated illness and risk in order to understand the unique communicative challenges involved in this area of contention. Arguing for greater critical engagement with policy, the article integrates policy research with social movements, subpolitics, and issue management literature. Drawing from activist discourse and multidisciplinary research, the article describes how a wide array of groups groups build visibility for corporate health effects, create the potential for networking and collaboration, and politicize health by attributing illness to corporate behaviors. The discussion articulates the implications of this activism for health communication theory, research, and practice.

Critical care nurses' decision making: sedation assessment and management in intensive care.

2009-01-01

This study was designed to examine the decision making processes that nurses use when assessing and managing sedation for a critically ill patient, specifically the attributes and concepts used to determine sedation needs and the influence of a sedation guideline on the decision making processes. Sedation management forms an integral component of the care of critical care patients. Despite this, there is little understanding of how nurses make decisions regarding assessment and management of intensive care patients' sedation requirements. Appropriate nursing assessment and management of sedation therapy is essential to quality patient care. Observational study. Nurses providing sedation management for a critically ill patient were observed and asked to think aloud during two separate occasions for two hours of care. Follow-up interviews were conducted to collect data from five expert critical care nurses pre- and postimplementation of a sedation guideline. Data from all sources were integrated, with data analysis identifying the type and number of attributes and concepts used to form decisions. Attributes and concepts most frequently used related to sedation and sedatives, anxiety and agitation, pain and comfort and neurological status. On average each participant raised 48 attributes related to sedation assessment and management in the preintervention phase and 57 attributes postintervention. These attributes related to assessment (pre, 58%; post, 65%), physiology (pre, 10%; post, 9%) and treatment (pre, 31%; post, 26%) aspects of care. Decision making in this setting is highly complex, incorporating a wide range of attributes that concentrate primarily on assessment aspects of care. Clinical guidelines should provide support for strategies known to positively influence practice. Further, the education of nurses to use such guidelines optimally must take into account the highly complex iterative process and wide range of data sources used to make decisions.

Diarrhoea risk factors in enterally tube fed critically ill patients: a retrospective audit.

2010-12-01

Diarrhoea in the enterally tube fed (ETF) intensive care unit (ICU) patient is a multi-factorial problem. Diarrhoeal aetiologies in this patient cohort remain debatable; however, the consequences of diarrhoea have been well established and include electrolyte imbalance, dehydration, bacterial translocation, peri anal wound contamination and sleep deprivation. This study examined the incidence of diarrhoea and explored factors contributing to the development of diarrhoea in the ETF, critically ill, adult patient. After institutional ethical review and approval, a single centre medical chart audit was undertaken to examine the incidence of diarrhoea in ETF, critically ill patients. Retrospective, non-probability sequential sampling was used of all emergency admission adult ICU patients who met the inclusion/exclusion criteria. Fifty patients were audited. Faecal frequency, consistency and quantity were considered important criteria in defining ETF diarrhoea. The incidence of diarrhoea was 78%. Total patient diarrhoea days (r=0.422; p=0.02) and total diarrhoea frequency (r=0.313; p=0.027) increased when the patient was ETF for longer periods of time. Increased severity of illness, peripheral oxygen saturation (Sp02), glucose control, albumin and white cell count were found to be statistically significant factors for the development of diarrhoea. Diarrhoea in ETF critically ill patients is multi-factorial. The early identification of diarrhoea risk factors and the development of a diarrhoea risk management algorithm is recommended.

To establish the experts consensus on the right heart function management in critically ill patients. The panel of consensus was composed of 30 experts in critical care medicine who are all members of Critical Hemodynamic Therapy Collaboration Group (CHTC Group). Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. Then the Delphi method was adopted by 52 experts to reassess all the statements. (1) Right heart function is prone to be affected in critically illness, which will result in a auto-exaggerated vicious cycle. (2) Right heart function management is a key step of the hemodynamic therapy in critically ill patients. (3) Fluid resuscitation means the process of fluid therapy through rapid adjustment of intravascular volume aiming to improve tissue perfusion. Reversed fluid resuscitation means reducing volume. (4) The right ventricle afterload should be taken into consideration when using stroke volume variation (SVV) or pulse pressure variation (PPV) to assess fluid responsiveness.(5)Volume overload alone could lead to septal displacement and damage the diastolic function of the left ventricle. (6) The Starling curve of the right ventricle is not the same as the one applied to the left ventricle,the judgement of the different states for the right ventricle is the key of volume management. (7) The alteration of right heart function has its own characteristics, volume assessment and adjustment is an important part of the treatment of right ventricular dysfunction (8) Right ventricular enlargement is the prerequisite for increased cardiac output during reversed fluid resuscitation; Nonetheless, right heart enlargement does not mandate reversed fluid resuscitation.(9)Increased pulmonary vascular resistance induced by a variety of factors could affect right heart function by obstructing the blood flow. (10) When pulmonary hypertension was detected in clinical scenario, the differentiation of critical care-related pulmonary hypertension should be a priority. (11) Attention should be paid to the change of right heart function before and after implementation of mechanical ventilation and adjustment of ventilator parameter. (12) The pulmonary arterial pressure should be monitored timingly when dealing with critical care-related pulmonary hypertension accompanied with circulatory failure.(13) The elevation of pulmonary aterial pressure should be taken into account in critical patients with acute right heart dysfunction. (14) Prone position ventilation is an important measure to reduce pulmonary vascular resistance when treating acute respiratory distress syndrome patients accompanied with acute cor pulmonale. (15) Attention should be paid to right ventricle-pulmonary artery coupling during the management of right heart function. (16) Right ventricular diastolic function is more prone to be affected in critically ill patients, the application of critical ultrasound is more conducive to quantitative assessment of right ventricular diastolic function. (17) As one of the parameters to assess the filling pressure of right heart, central venous pressure can be used to assess right heart diastolic function. (18). The early and prominent manifestation of non-focal cardiac tamponade is right ventricular diastolic involvement, the elevated right atrial pressure should be noticed. (19) The effect of increased intrathoracic pressure on right heart diastolic function should be valued. (20) Ttricuspid annular plane systolic excursion (TAPSE) is an important parameter that reflects right ventricular systolic function, and it is recommended as a general indicator of critically ill patient. (21) Circulation management with right heart protection as the core strategy is the key point of the treatment of acute respiratory distress syndrome. (22) Right heart function involvement after cardiac surgery is very common and should be highly valued. (23) Right ventricular dysfunction should not be considered as a routine excuse for maintaining higher central venous pressure. (24) When left ventricular dilation, attention should be paid to the effect of left ventricle on right ventricular diastolic function. (25) The impact of left ventricular function should be excluded when the contractility of the right ventricle is decreased. (26) When the right heart load increases acutely, the shunt between the left and right heart should be monitored. (27) Attention should be paid to the increase of central venous pressure caused by right ventricular dysfunction and its influence on microcirculation blood flow. (28) When the vasoactive drugs was used to reduce the pressure of pulmonary circulation, different effects on pulmonary and systemic circulation should be evaluated. (29) Right atrial pressure is an important factor affecting venous return. Attention should be paid to the influence of the pressure composition of the right atrium on the venous return. (30) Attention should be paid to the role of the right ventricle in the acute pulmonary edema. (31) Monitoring the difference between the mean systemic filling pressure and the right atrial pressure is helpful to determine whether the infusion increases the venous return. (32) Venous return resistance is often considered to be a insignificant factor that affects venous return, but attention should be paid to the effect of the specific pathophysiological status, such as intrathoracic hypertension, intra-abdominal hypertension and so on. Consensus can promote right heart function management in critically ill patients, optimize hemodynamic therapy, and even affect prognosis.

Clinical presentation and management of severe Ebola virus disease.

PubMed

West, T Eoin; von Saint André-von Arnim, Amélie

2014-11-01

Clinicians caring for patients infected with Ebola virus must be familiar not only with screening and infection control measures but also with management of severe disease. By integrating experience from several Ebola epidemics with best practices for managing critical illness, this report focuses on the clinical presentation and management of severely ill infants, children, and adults with Ebola virus disease. Fever, fatigue, vomiting, diarrhea, and anorexia are the most common symptoms of the 2014 West African outbreak. Profound fluid losses from the gastrointestinal tract result in volume depletion, metabolic abnormalities (including hyponatremia, hypokalemia, and hypocalcemia), shock, and organ failure. Overt hemorrhage occurs infrequently. The case fatality rate in West Africa is at least 70%, and individuals with respiratory, neurological, or hemorrhagic symptoms have a higher risk of death. There is no proven antiviral agent to treat Ebola virus disease, although several experimental treatments may be considered. Even in the absence of antiviral therapies, intensive supportive care has the potential to markedly blunt the high case fatality rate reported to date. Optimal treatment requires conscientious correction of fluid and electrolyte losses. Additional management considerations include searching for coinfection or superinfection; treatment of shock (with intravenous fluids and vasoactive agents), acute kidney injury (with renal replacement therapy), and respiratory failure (with invasive mechanical ventilation); provision of nutrition support, pain and anxiety control, and psychosocial support; and the use of strategies to reduce complications of critical illness. Cardiopulmonary resuscitation may be appropriate in certain circumstances, but extracorporeal life support is not advised. Among other ethical issues, patients' medical needs must be carefully weighed against healthcare worker safety and infection control concerns. However, meticulous attention to the use of personal protective equipment and strict adherence to infection control protocols should permit the safe provision of intensive treatment to severely ill patients with Ebola virus disease.

Impact of late fluid balance on clinical outcomes in the critically ill surgical and trauma population.

2015-12-01

Management of fluid status in critically ill patients poses a significant challenge due to limited literature. This study aimed to determine the impact of late fluid balance management after initial adequate fluid resuscitation on in-hospital mortality for critically ill surgical and trauma patients. This single-center retrospective cohort study included 197 patients who underwent surgical procedure within 24 hours of surgical intensive care unit admission. Patients with high fluid balance on postoperative day 7 (>5 L) were compared with those with a low fluid balance (≤5 L) with a primary end point of in-hospital mortality. Subgroup analyses were performed based on diuretic administration, diuretic response, and type of surgery. High fluid balance was associated with significantly higher in-hospital mortality (30.2 vs 3%, P<.001) compared with low fluid balance; this relationship remained after multivariable regression analysis. High fluid balance was associated with increased mortality, independent of diuretic administration, diuretic response, and type of surgery. Consistent with previous literature, high fluid balance on postoperative day 7 was associated with increased in-hospital mortality. Patients who received and responded to diuretic therapy did not demonstrate improved clinical outcomes, which questions their use in the postoperative period. Copyright © 2015 Elsevier Inc.

In general, social support from family members affects chronic illness outcomes, but evidence on which specific family behaviors are most important to adult patient outcomes has not been summarized. We systematically reviewed studies examining the effect of specific family member behaviors and communication patterns on adult chronic illness self-management and clinical outcomes. Thirty studies meeting inclusion criteria were identified, representing 22 participant cohorts, and including adults with arthritis, chronic cardiovascular disease, diabetes, and/or end stage renal disease. Family emphasis on self-reliance and personal achievement, family cohesion, and attentive responses to symptoms were associated with better patient outcomes. Critical, overprotective, controlling, and distracting family responses to illness management were associated with negative patient outcomes. Study limitations included cross-sectional designs (11 cohorts), however results from longitudinal studies were similar. Findings suggest that future interventions aiming to improve chronic illness outcomes should emphasize increased family use of attentive coping techniques and family support for the patient’s autonomous motivation.

We reviewed the literature on standard case management (SCM), intensive case management (ICM), assertive community treatment (ACT), and critical time intervention (CTI) for homeless adults. We searched databases for peer-reviewed English articles published from 1985 to 2011 and found 21 randomized controlled trials or quasi-experimental studies comparing case management to other services. We found little evidence for the effectiveness of ICM. SCM improved housing stability, reduced substance use, and removed employment barriers for substance users. ACT improved housing stability and was cost-effective for mentally ill and dually diagnosed persons. CTI showed promise for housing, psychopathology, and substance use and was cost-effective for mentally ill persons. More research is needed on how case management can most effectively support rapid-rehousing approaches to homelessness.

Aspiration in critically ill patients frequently causes severe co-morbidity. We evaluated a diagnostic protocol using routine FEES in critically ill patients at risk to develop aspiration following extubation. We instructed intensive care unit physicians on specific risk factors for and clinical signs of aspiration following extubation in critically ill patients and offered bedside FEES for such patients. Over a 45-month period, we were called to perform 913 endoscopic examinations in 553 patients. Silent aspiration or aspiration with acute symptoms (cough or gag reflex as the bolus passed into the trachea) was detected in 69.3% of all patients. Prolonged non-oral feeding via a naso-gastric tube was initiated in 49.7% of all patients. In 13.2% of patients, a percutaneous endoscopic gastrostomy was initiated as a result of FEES findings, and in 6.3% an additional tracheotomy to prevent aspiration had to be initiated. In 59 out of 258 patients (22.9%), tracheotomies were closed, and 30.7% of all 553 patients could be managed with the immediate onset of an oral diet and compensatory treatment procedures. Additional radiological examinations were not required. FEES in critically ill patients allows for a rapid evaluation of deglutition and for the immediate initiation of symptom-related rehabilitation or for an early resumption of oral feeding.

Five million Americans require admission to ICUs annually owing to life-threatening illnesses. Recent medical advances have resulted in higher survival rates for critically ill patients, who often have significant cognitive, physical, and psychological sequelae, known as postintensive care syndrome (PICS). This growing population threatens to overwhelm the current U.S. health care system, which lacks established clinical models for managing their care. Novel innovative models are urgently needed. To this end, the pulmonary/critical care and geriatrics divisions at the Indiana University School of Medicine joined forces to develop and implement a collaborative care model, the Critical Care Recovery Center (CCRC). Its mission is to maximize the cognitive, physical, and psychological recovery of ICU survivors. Developed around the principles of implementation and complexity science, the CCRC opened in 2011 as a clinical center with a secondary research focus. Care is provided through a pre-CCRC patient and caregiver needs assessment, an initial diagnostic workup visit, and a follow-up visit that includes a family conference. With its sole focus on the prevention and treatment of PICS, the CCRC represents an innovative prototype aimed at modifying post-critical illness morbidities and improving the ICU survivor's quality of life.

Nutritional support is an important means to treat the patients with chronic critical illness for commonly associated malnutrition. Refeeding syndrome is a serious complication during the process, mainly manifested as severe electrolyte with hypophosphataemia being the most common. Refeeding syndrome is not uncommon but it is often ignored. In our future clinical work, we need to recognize this chinical situation and use preventative and treatment measures. According to NICE clinical nutrition guideline, we discussed the risk factors, treatment methods and preventive measures of refeeding syndrome in patients with chronic critical illness. We argued that for patients with high risk refeeding syndrome, nutritional support treatment should be initially low calorie and slowly increased to complete requirement. Circulation capacity should be recovered, fluid balance must be closely monitored and supplement of vitamins, microelement, electrolytes should be noted. After the emergence of refeeding syndrome, we should reduce or even stop the calorie intake, give an active treatment for electrolyte disorder, provide vitamin B, and maintain the functions of multiple organs.

In low resource settings, an inadequate number of trained healthcare workers and high volumes of children presenting to Primary Healthcare Centers (PHC) result in prolonged waiting times and significant delays in identifying and evaluating critically ill children. The Sick Children Require Emergency Evaluation Now (SCREEN) program, a simple six-question screening algorithm administered by lay healthcare workers, was developed in 2014 to rapidly identify critically ill children and to expedite their care at the point of entry into a clinic. We sought to determine the impact of SCREEN on waiting times for critically ill children post real world implementation in Cape Town, South Africa. This is a prospective, observational implementation-effectiveness hybrid study that sought to determine: (1) the impact of SCREEN implementation on waiting times as a primary outcome measure, and (2) the effectiveness of the SCREEN tool in accurately identifying critically ill children when utilised by the QM and adherence by the QM to the SCREEN algorithm as secondary outcome measures. The study was conducted in two phases, Phase I control (pre-SCREEN implementation- three months in 2014) and Phase II (post-SCREEN implementation-two distinct three month periods in 2016). In Phase I, 1600 (92.38%) of 1732 children presenting to 4 clinics, had sufficient data for analysis and comprised the control sample. In Phase II, all 3383 of the children presenting to the 26 clinics during the sampling time frame had sufficient data for analysis. The proportion of critically ill children who saw a professional nurse within 10 minutes increased tenfold from 6.4% to 64% (Phase I to Phase II) with the median time to seeing a professional nurse reduced from 100.3 minutes to 4.9 minutes, (p < .001, respectively). Overall layperson screening compared to Integrated Management of Childhood Illnesses (IMCI) designation by a nurse had a sensitivity of 94.2% and a specificity of 88.1%, despite large variance in adherence to the SCREEN algorithm across clinics. The SCREEN program when implemented in a real-world setting can significantly reduce waiting times for critically ill children in PHCs, however further work is required to improve the implementation of this innovative program.

Physiotherapy in Critical Care in Australia

PubMed Central

Haines, Kimberley; Denehy, Linda

2012-01-01

A physiotherapist is part of the multidisciplinary team in most intensive care units in Australia. Physiotherapists are primary contact practitioners and use a comprehensive multisystem assessment that includes the respiratory, cardiovascular, neurological, and musculoskeletal systems to formulate individualized treatment plans. The traditional focus of treatment has been the respiratory management of both intubated and spontaneously breathing patients. However, the emerging evidence of the longstanding physical impairment suffered by survivors of intensive care has resulted in physiotherapists re-evaluating treatment priorities to include exercise rehabilitation as a part of standard clinical practice. The goals of respiratory physiotherapy management are to promote secretion clearance, maintain or recruit lung volume, optimize oxygenation, and prevent respiratory complications in both the intubated and spontaneously breathing patient. In the intubated patient, physiotherapists commonly employ manual and ventilator hyperinflation and positioning as treatment techniques whilst in the spontaneously breathing patients there is an emphasis on mobilization. Physiotherapists predominantly use functional activities for the rehabilitation of the critically ill patient in intensive care. While variability exists between states and centers, Australian physiotherapists actively treat critically ill patients targeting interventions based upon research evidence and individualized assessment. A trend toward more emphasis on exercise rehabilitation over respiratory management is evident. PMID:22807651

Metabolic Management during Critical Illness: Glycemic Control in the ICU.

PubMed

Honiden, Shyoko; Inzucchi, Silvio E

2015-12-01

Hyperglycemia is a commonly encountered metabolic derangement in the ICU. Important cellular pathways, such as those related to oxidant stress, immunity, and cellular homeostasis, can become deranged with prolonged and uncontrolled hyperglycemia. There is additionally a complex interplay between nutritional status, ambient glucose concentrations, and protein catabolism. While the nuances of glucose management in the ICU have been debated, results from landmark studies support the notion that for most critically ill patients moderate glycemic control is appropriate, as reflected by recent guidelines. Beyond the target population and optimal glucose range, additional factors such as hypoglycemia and glucose variability are important metrics to follow. In this regard, new technologies such as continuous glucose sensors may help alleviate the risks associated with such glucose fluctuations in the ICU. In this review, we will explore the impact of hyperglycemia upon critical cellular pathways and how nutrition provided in the ICU affects blood glucose. Additionally, important clinical trials to date will be summarized. A practical and comprehensive approach to glucose management in the ICU will be outlined, touching upon important issues such as glucose variability, target population, and hypoglycemia.

Spontaneous bacterial peritonitis is a complication of ascitic patients with end-stage liver disease (ESLD); spontaneous fungal peritonitis (SFP) is a complication of ESLD less known and described. ESLD is associated to immunodepression and the resulting increased susceptibility to infections. Recent perspectives of the management of the critically ill patient with ESLD do not specify the rate of isolation of fungi in critically ill patients, not even the antifungals used for the prophylaxis, neither optimal treatment. We reviewed, in order to focus the epidemiology, characteristics, and, considering the high mortality rate of SFP, the use of optimal empirical antifungal therapy the current literature.

Economic hardship associated with managing chronic illness: a qualitative inquiry

2009-01-01

Background Chronic illness and disability can have damaging, even catastrophic, socioeconomic effects on individuals and their households. We examined the experiences of people affected by chronic heart failure, complicated diabetes and chronic obstructive pulmonary disease to inform patient centred policy development. This paper provides a first level, qualitative understanding of the economic impact of chronic illness. Methods Interviews were conducted with patients aged between 45 and 85 years who had one or more of the index conditions and family carers from the Australian Capital Territory and Western Sydney, Australia (n = 66). Content analysis guided the interpretation of data. Results The affordability of medical treatments and care required to manage illness were identified as the key aspects of economic hardship, which compromised patients' capacity to proactively engage in self-management and risk reduction behaviours. Factors exacerbating hardship included ineligibility for government support, co-morbidity, health service flexibility, and health literacy. Participants who were on multiple medications, from culturally and linguistically diverse or Indigenous backgrounds, and/or not in paid employment, experienced economic hardship more harshly and their management of chronic illness was jeopardised as a consequence. Economic hardship was felt among not only those ineligible for government financial supports but also those receiving subsidies that were insufficient to meet the costs of managing long-term illness over and above necessary daily living expenses. Conclusion This research provides insights into the economic stressors associated with managing chronic illness, demonstrating that economic hardship requires households to make difficult decisions between care and basic living expenses. These decisions may cause less than optimal health outcomes and increased costs to the health system. The findings support the necessity of a critical analysis of health, social and welfare policies to identify cross-sectoral strategies to alleviate such hardship and improve the affordability of managing chronic conditions. In a climate of global economic instability, research into the economic impact of chronic illness on individuals' health and well-being and their disease management capacity, such as this study, provides timely evidence to inform policy development.

Ventilator-associated pneumonia management in critical illness.

Albertos, Raquel; Caralt, Berta; Rello, Jordi

2011-03-01

Ventilator-associated pneumonia (VAP) is a frequent adverse event in the intensive care unit.We review recent publications about the management and prevention of VAP. The latest care bundles introduced standard interventions to facilitate implementation of evidence-based clinical guidelines and to improve the outcome of patients. Recent studies find that prevention management of ventilated patients decreases the risk of VAP. Enteral feeding, considered a risk factor for VAP, currently has been recommended, with appropriate administration, for all critical ill patients if no contraindications exist. In view of the recently available data, it can be concluded that the implementation of care bundles on the general management of ventilated patients in daily practice has reduced the VAP rates. The main pharmacological measures to prevent VAP are proper hands hygiene, high nurse-to-patient ratio, avoid unnecessary transfer of ventilated patients, use of noninvasive mechanical ventilation, shortening weaning period, avoid the use of nasal intubation, prevent bio-film deposition in endotracheal tube, aspiration of subglottic secretions, maintenance of adequate pressure of endotracheal cuffs, avoid manipulation of ventilator circuits, semi-recumbent position and adequate enteral feeding.In addition, updated guidelines incorporate more comprehensive diagnostic protocols to the evidence-based management of VAP.

Severely burned patients typically experience a systemic response expressed as increased metabolism, inflammation, alteration of cardiac and immune function, and associated hyperglycemia. Hyperglycemia has been associated with an increased risk of morbidity and mortality in critically ill patients. Until recently and for many years, hyperglycemia has been expectantly managed and considered a normal and desired response of an organism to stress. However, findings reported from recent studies now suggest beneficial effects of intensive insulin treatment for critically-ill patients. The literature on the management of hyperglycemia in severely burned patients is sparse, with most of the available studies involving only small numbers of burned patients. The purpose of this article is to describe the pathophysiology of hyperglycemia following severe burns and review the available literature on the outcome of intensive insulin treatment and other anti-hyperglycemic modalities in burned patients in an evidence-based-medicine approach.

Blood loss due to phlebotomy leads to hospital-acquired anemia and more frequent blood transfusions that may be associated with increased risk of morbidity and mortality in critically ill patients. Multiple blood conservation strategies have been proposed in the context of patient blood management to minimize blood loss. Here, we evaluated a new small-volume sodium citrate collection tube for coagulation testing in critically ill patients. In 46 critically adult ill patients admitted to an interdisciplinary intensive care unit, we prospectively compared small-volume (1.8 mL) sodium citrate tubes with the conventional (3 mL) sodium citrate tubes. The main inclusion criterium was a proven coagulopathy (Quick < 60% and/or aPTT > 40 second) due to anticoagulation therapy or perioperative coagulopathy. In total, 92 coagulation analyses were obtained. Linear correlation analysis detected a positive relationship for 7 coagulation parameters (Prothrombin Time, r = 0.987; INR, r = 0.985; activated Partial Thromboplastin Time, r = 0.967; Thrombin Clotting Time, r = 0.969; Fibrinogen, r = 0.986; Antithrombin, r = 0.988; DDimer, r = 0.969). Bland-Altman analyses revealed an absolute mean of differences of almost zero. Ninety-five percent of data were within two standard deviations of the mean difference suggesting interchangeability. As systematic deviations between measured parameters of the two tubes were very unlikely, test results of small-volume (1.8 mL) sodium citrate tubes were equal to conventional (3 mL) sodium citrate tubes and can be considered interchangeable. Small-volume sodium citrate tubes reduced unnecessary diagnostic-related blood loss by about 40% and, therefore, should be the new standard of care for routine coagulation analysis in critically ill patients.

To investigate glycaemic levels in critically ill neonates with inherited metabolic disorders of intoxication. Thirty-nine neonates with a median age of 7 days (0-24) were retrospectively included (urea cycle disorders (n = 18), maple syrup disease (n = 13), organic acidemias (n = 8)). Twenty-seven neonates were intubated, 21 were haemodialysed and 6 died. During the first 3 days, median total and peak blood glucose (BG) levels were 7.1 mmol/L (0.9-50) and 10 mmol/L (5.1-50), respectively. The median glucose intake rate was 11 mg/kg/min (2.7-15.9). Fifteen and 23 neonates exhibited severe hyperglycaemia (≥2 BG levels >12 mmol/L) and mild hyperglycaemia (≥2 BG levels >7 and ≤12 mmol/L), respectively. Glycaemic levels and number of hyperglycaemic neonates decreased over the first 3 days (p < 0.001) while total glucose intake rate was stable (p = 0.11). Enteral route of glucose intake was associated with a lower number of hyperglycaemic neonates (p = 0.04) and glycaemic level (p = 0.02). Hyperglycaemia is common in critically ill neonates receiving high glucose intake with inherited metabolic disorders of intoxication. Physicians should decrease the rate of total glucose intake and begin enteral feeding as quickly as possible in cases of persistent hyperglycaemia. • The risk of hyperglycaemia in the acute phase of critical illness is high. What is New: • Hyperglycaemia is common in the initial management of critically ill neonates with inherited metabolic disorders of intoxication receiving high glucose intake.

Background and Aims: The association between hyperglycemia and mortality is believed to be influenced by the presence of diabetes mellitus (DM). In this study, we evaluated the effect of preexisting hyperglycemia on the association between acute blood glucose management and mortality in critically ill patients. The primary objective of the study was the relationship between HbA1c and mortality in critically ill patients. Secondary objectives of the study were relationship between Intensive Care Unit (ICU) admission blood glucose and glucose control during ICU stay with mortality in critically ill patients. Materials and Methods: Five hundred patients admitted to two ICUs were enrolled. Blood sugar and hemoglobin A1c (HbA1c) concentrations on ICU admission were measured. Age, sex, history of DM, comorbidities, Acute Physiology and Chronic Health Evaluation II score, sequential organ failure assessment score, hypoglycemic episodes, drug history, mortality, and development of acute kidney injury and liver failure were noted for all patients. Results: Without considering the history of diabetes, nonsurvivors had significantly higher HbA1c values compared to survivors (7.25 ± 1.87 vs. 6.05 ± 1.22, respectively, P < 0.001). Blood glucose levels in ICU admission showed a significant correlation with risk of death (P < 0.006, confidence interval [CI]: 1.004–1.02, relative risk [RR]: 1.01). Logistic regression analysis revealed that HbA1c increased the risk of death; with each increase in HbA1c level, the risk of death doubled. However, this relationship was not statistically significant (P: 0.161, CI: 0.933–1.58, RR: 1.2). Conclusions: Acute hyperglycemia significantly affects mortality in the critically ill patients; this relation is also influenced by chronic hyperglycemia. PMID:27076705

Being a nurse in an intensive care unit entails caring for seriously ill patients. Vasoactive drugs are one of the tools that are used to restore adequate circulation. Critical care nurses often manage and administer these potent drugs after medical advice from physicians. To describe the experiences of critical care nurses learning to manage vasoactive drugs, and to highlight the competence required to manage vasoactive drugs. Twelve critical care nurses from three hospitals in Sweden were interviewed. Qualitative content analysis was applied. The theme "becoming proficient requires accuracy, practice and precaution" illustrated how critical care nurses learn to manage vasoactive drugs. Learning included developing cognitive, psychomotor, and effective skills. Sources for knowledge refers to specialist education combined with practical exercises, collegial support, and accessible routine documents. The competence required to manage vasoactive drugs encompassed well-developed safety thinking that included being careful, in control, and communicating failures. Specific skills were required such as titrating doses, being able to analyse and evaluate the technological assessments, adapting to the situation, and staying calm. Learning to manage vasoactive drugs requires a supportive introduction for novices, collegial support, lifelong learning, and a culture of safety. Copyright © 2016 Elsevier Ltd. All rights reserved.

To report the successful management of thyrotoxicosis in a seriously ill 47-year-old man with a perforated gastric ulcer in whom oral intake was contraindicated. Our patient was treated with 400 mg of propylthiouracil (PTU) every 6 hours in the form of specially prepared suppositories for rectal administration, together with intravenously infused esmolol. We were able to demonstrate substantial absorption of PTU administered by means of rectal suppositories. Serum levels of PTU were maintained within the high therapeutic range for 5 days until the patient was able to tolerate orally administered therapy. The patient improved clinically during this treatment. This case strongly supports the rectal administration of PTU in suppository form as an appropriate alternative route in any patient with thyrotoxicosis, including the critically ill patient, when oral administration is not possible.

2014-01-01

Critical illness polyneuropathy and critical illness myopathy are frequent complications of severe illness that involve sensorimotor axons and skeletal muscles, respectively. Clinically, they manifest as limb and respiratory muscle weakness. Critical illness polyneuropathy/myopathy in isolation or combination increases intensive care unit morbidity via the inability or difficulty in weaning these patients off mechanical ventilation. Many patients continue to suffer from decreased exercise capacity and compromised quality of life for months to years after the acute event. Substantial progress has been made lately in the understanding of the pathophysiology of critical illness polyneuropathy and myopathy. Clinical and ancillary test results should be carefully interpreted to differentiate critical illness polyneuropathy/myopathy from similar weaknesses in this patient population. The present review is aimed at providing the latest knowledge concerning the pathophysiology of critical illness polyneuropathy/myopathy along with relevant clinical, diagnostic, differentiating, and treatment information for this debilitating neurological disease.

The most recent Confidential Enquiry into Maternal Deaths (CMACE, 2011) identified human errors, specifically those of midwives and obstetricians/doctors as a fundamental component in contributing to maternal death in the U.K. This paper discusses these findings and outlines a project to provide training in Maternal-Acute Illness Management (M-AIM) to final year student midwives. Contents of the program are designed to educate and simulate AIM skills and increase confidence and clinical ability in early recognition, management and referral of the acutely ill woman. An outline of the Maternal-AIM program delivered at the University of Salford (Greater Manchester, UK) is presented to illustrate how this particular institution has responded to a perceived need voiced by local midwifery leaders. It is proposed that developing this area of expertise in the education system will better prepare student midwives for contemporary midwifery practice. Crown Copyright © 2014.

Invasive infections caused by Candida spp. in critically ill patients may significantly worsen their prognosis, so it is of great importance to establish an early detection and a suitable therapeutic strategy. The objective of this study was to define the differential role of echinocandins in treating certain critical patient profiles. A scientific committee of 9 experts in infectious diseases, critical care, microbiology, and hospital pharmacy reviewed the existing evidence on the treatment of candidemia and invasive candidiasis in critically ill patients. After that, a questionnaire with 35 items was elaborated to be agreed by 26 specialists in the aforementioned disciplines using a modified Delphi method. After two rounds of evaluation, a consensus was reached in terms of agreement in 66% of the items. Some of the consensuses achieved included: it is not necessary to adjust the dose of echinocandins during renal replacement therapy; the echinocandins are the empirical and/or directed treatment of choice for candidemia and invasive candidiasis associated with biofilms; these drugs may be used in the antifungal prophylaxis of high-risk liver transplantation. In the absence of additional clinical data, it should be noted that micafungin is the echinocandin with the most available scientific evidence. The experts consulted showed a high degree of agreement on some of the most controversial aspects regarding the management of candidemia and invasive candidiasis in critical patients, which could inform of practical recommendations for their treatment.

Dysphagia is a severe complication in critically ill patients and affects more than half the patients in an intensive care unit. Dysphagia also has a strong impact on morbidity and mortality. Risk factors for the development of dysphagia are neurological diseases, age >55-70 years, intubation >7 days and sepsis. With increasing numbers of long-term survivors chronic dysphagia is becoming an increasing problem. There is not much knowledge on the influence of specific diseases, including the direct impact of sepsis on the development of dysphagia. Fiberoptic evaluation of swallowing is a standardized tool for bedside evaluation, helping to plan swallowing training during the acute phase and to decrease the rate of chronic dysphagia. For evaluation of chronic dysphagia even more extensive diagnostic tools as well as several options of stepwise rehabilitation using restitution, compensation and adaption strategies for swallowing exist. Currently it seems that these options are not being sufficiently utilized. In general, there is a need for controlled clinical trials analyzing specific swallowing rehabilitation concepts for former critically ill patients and long-term survivors.

In prolonged non-obese critically ill patients, preservation of adipose tissue is prioritized over that of the skeletal muscle and coincides with increased adipogenesis. However, we recently demonstrated that in obese critically ill mice, this priority was switched. In the obese, the use of abundantly available adipose tissue-derived energy substrates was preferred and counteracted muscle wasting. These observations suggest that different processes are ongoing in adipose tissue of lean vs. overweight/obese critically ill patients. We hypothesize that to preserve adipose tissue mass during critical illness, adipogenesis is increased in prolonged lean critically ill patients, but not in overweight/obese critically ill patients, who enter the ICU with excess adipose tissue. To test this, we studied markers of adipogenesis in subcutaneous and visceral biopsies of matched lean (n = 24) and overweight/obese (n = 24) prolonged critically ill patients. Secondly, to further unravel the underlying mechanism of critical illness-induced adipogenesis, local production of eicosanoid PPARγ agonists was explored, as well as the adipogenic potential of serum from matched lean (n = 20) and overweight/obese (n = 20) critically ill patients. The number of small adipocytes, PPARγ protein, and CEBPB expression were equally upregulated (p ≤ 0.05) in subcutaneous and visceral adipose tissue biopsies of lean and overweight/obese prolonged critically ill patients. Gene expression of key enzymes involved in eicosanoid production was reduced (COX1, HPGDS, LPGDS, ALOX15, all p ≤ 0.05) or unaltered (COX2, ALOX5) during critical illness, irrespective of obesity. Gene expression of PLA2G2A and ALOX15B was upregulated in lean and overweight/obese patients (p ≤ 0.05), whereas their end products, the PPARγ-activating metabolites 15s-HETE and 9-HODE, were not increased in the adipose tissue. In vitro, serum of lean and overweight/obese prolonged critically ill patients equally stimulated adipocyte proliferation (p ≤ 0.05) and differentiation (lipid accumulation, DLK1, and CEBPB expression, p ≤ 0.05). Contrary to what was hypothesized, adipogenesis increased independently of initial BMI in prolonged critically ill patients. Not the production of local eicosanoid PPARγ agonists but circulating adipogenic factors seem to be involved in critical illness-induced adipogenesis. Importantly, our findings suggest that abundantly available energy substrates from the adipose tissue, rather than excess adipocytes, can play a beneficial role during critical illness.

To critically review, analyze, and synthesize the literature on parenting stress among caregivers of children with asthma, cancer, cystic fibrosis, diabetes, epilepsy, juvenile rheumatoid arthritis, and/or sickle cell disease. Method PsychInfo, MEDLINE, and Cumulative Index to Nursing and Allied Health Literature were searched according to inclusion criteria. Meta-analysis of 13 studies and qualitative analysis of 96 studies was conducted. Results Caregivers of children with chronic illness reported significantly greater general parenting stress than caregivers of healthy children (d = .40; p = ≤.0001). Qualitative analysis revealed that greater general parenting stress was associated with greater parental responsibility for treatment management and was unrelated to illness duration and severity across illness populations. Greater parenting stress was associated with poorer psychological adjustment in caregivers and children with chronic illness. Conclusion Parenting stress is an important target for future intervention. General and illness-specific measures of parenting stress should be used in future studies.

Severe infections of the respiratory tracts of critically ill patients are common and associated with excess morbidity and mortality. Piperacillin is commonly used to treat pulmonary infections in critically ill patients. Adequate antibiotic concentration in the epithelial lining fluid (ELF) of the lung is essential for successful treatment of pulmonary infection. To compare piperacillin pharmacokinetics/pharmacodynamics in the serum and ELF of healthy volunteers and critically ill patients. Piperacillin concentrations in the serum and ELF of healthy volunteers and critically ill patients were compared using population methodologies. Median piperacillin exposure was significantly higher in the serum and the ELF of critically ill patients compared with healthy volunteers. The IQR for serum piperacillin exposure in critically ill patients was six times greater than for healthy volunteers. The IQR for piperacillin exposure in the ELF of critically ill patients was four times greater than for healthy volunteers. The median pulmonary piperacillin penetration ratio was 0.31 in healthy volunteers and 0.54 in critically ill patients. Greater variability in serum and ELF piperacillin concentrations is observed in critically ill patients compared with healthy adult subjects and must be considered in the development of dosage regimens. Pulmonary penetration of antimicrobial agents should be studied in critically ill patients, as well as healthy volunteers, during drug development to ensure appropriate dosing of patients with pneumonia. © The Author(s) 2018.

Rentmeester, Christy A.

2013-01-01

We typically think of acutely and chronically mentally ill patients as those who belong in psychiatric hospitals and the latter category of patients belonging in “regular” hospitals, but the intersection of physical and mental illness draws attention to important challenges for policy makers and organizational leaders. This article illuminates some broad trends in the health status of people with mental illnesses, canvasses important features of inequalities suffered by people with mental illnesses, and suggests strategies for systemic reform. Most reform recommendations I offer are in the area of healthcare organization leadership and management. Other key reforms will likely be legislative, regulatory, and insurance-related. Social and cultural reforms in organizational practices and structures will also be critical. PMID:24596844

An analysis of the stressors and coping strategies of Chinese adults with a partner admitted to an intensive care unit in Hong Kong: an exploratory study.

PubMed

Chan, Keung-Sum; Twinn, Sheila

2007-01-01

The aim of this study was to identify the major stressors affecting Chinese adults whose partner had been admitted to an intensive care unit and to understand the major coping strategies employed to manage such stressors. Recently a greater number of patients of higher acuity have been admitted to intensive care units and survive lengthy illnesses of an unpredictable course. Such critical illnesses have been identified as a major life event to family members of these patients. Little is known, however, about the stressors and coping mechanisms of Chinese adults whose critically ill partner is admitted to an intensive care unit. An exploratory qualitative design was selected to achieve the aims of the study. A purposive sample of 10 Chinese adults with a partner in an intensive care unit of a regional general hospital in Hong Kong participated in tape-recorded semi-structured interviews. Content analysis was employed to analyse the translated interviews. Categories of stressors included uncertainty, difficulties in communication, changes in roles and responsibilities, difficulties in decision making, financial strain as well as changes in relationships. Analysis identified a range of coping strategies which included seeking information, seeking support, reliance on cultural beliefs and practices, turning to religious beliefs, maintaining hope and acceptance of illness. The findings demonstrate the importance of cultural beliefs and practices in determining the coping mechanisms employed to manage the stressors identified by this sample of Chinese adults. Such findings indicate the use of both internal and external coping strategies in order to maintain equilibrium in the family. Implications for nursing practice highlight the significance of seeking information throughout the critical period and also culturally appropriate support from healthcare professionals.

When the family member is a nurse: the role and needs of nurse family members during critical illness of a loved one.

Salmond, Susan W

2011-02-01

The aim of this study was to explore the experience of being a nurse family member of a relative hospitalised for a critical illness. This paper will describe how nurse family members viewed the challenges of the illness experience and the strategies used to manage the challenges and cope with their loved one's critical illness. A qualitative approach using open-ended, focused exploratory interviews was used. Theoretical sampling was used to obtain a total of 22 participants. The knowledge base of the nurse filtered the experience for the nurse family member and their nurse role identity infused each component of the experience. Nurse family members identified their primary role as maintaining guard to protect the patient and family. To accomplish this, six challenges were identified: masking heightened emotional turmoil; assuming the in-charge role; assessing and monitoring; seeking information and meaning; advocating; and, "letting go to assume family and self roles". Strategies to facilitate meeting these challenges are described. In order to provide family-centered care, the critical care nurse must recognise the unique needs of the "nurse family member." By empathising with the emotional experience, allowing the "in-charge" nurse family member to be part of the team, facilitating ongoing observation and monitoring by the nurse family member, seeking out and clarifying information for the nurse family member and partnering to advocate for the patient, the critical care nurse builds a relationship of trust that allows the nurse family member to assume their family role.

Burn specialists have long recognized the need for and have role modeled a comprehensive approach incorporating relief of distress as part of care during critical illness. More recently, palliative care specialists have become part of the healthcare team in many U.S. hospitals, especially larger academic institutions that are more likely to have designated burn centers. No current literature describes the intersection of palliative care and burn care or integration of primary and specialist palliative care in this unique context. This Perspective gives an overview of burn care; focuses on pain and other symptoms in burn intensive care unit settings; addresses special needs of critically ill burned patients, their families, and clinicians for high-quality palliative care; and highlights potential benefits of integrating primary and specialist palliative care in burn critical care. MEDLINE and the Cumulative Index to Nursing and Allied Health Literature were searched, and an e-mail survey was used to obtain information from U.S. Burn Fellowship Program directors about palliative medicine training. The Improving Palliative Care in the Intensive Care Unit Project Advisory Board synthesized published evidence with their own research and clinical experience in preparing this article. Mortality and severe morbidity for critically ill burned patients remains high. American Burn Association guidelines lay the foundation for a robust system of palliative care delivery, embedding palliative care principles and processes in intensive care by burn providers. Understanding basic burn care, challenges for symptom management and communication, and the culture of the particular burn unit, can optimize quality and integration of primary and specialist palliative care in this distinctive setting.

Dependency in Critically Ill Patients

PubMed Central

Yang, Rumei

2016-01-01

By necessity, critically ill patients admitted to intensive care units (ICUs) have a high level of dependency, which is linked to a variety of negative feelings, such as powerlessness. However, the term dependency is not well defined in the critically ill patients. The concept of “dependency” in critically ill patients was analyzed using a meta-synthesis approach. An inductive process described by Deborah Finfgeld-Connett was used to analyze the data. Overarching themes emerged that reflected critically ill patients’ experience and meaning of being in dependency were (a) antecedents: dependency in critically ill patients was a powerless and vulnerable state, triggered by a life-threatening crisis; (b) attributes: the characteristic of losing “self” was featured by dehumanization and disembodiment, which can be alleviated by a “self”-restoring process; and (c) outcomes: living with dependency and coping with dependency. The conceptual model explicated here may provide a framework for understanding dependency in critically ill patients. PMID:28462328

Objective To review how disability can develop in older adults with critical illness and to explore ways to reduce long-term disability following critical illness. Data Sources Review of the literature describing post-critical illness disability in older adults and expert opinion. Results We identified 19 studies evaluating disability outcomes in critically ill patients age 65 years and older. Newly acquired disability in activities of daily living, instrumental activities of daily living and mobility activities was commonplace among older adults who survived a critical illness. Incident dementia and less-severe cognitive impairment was also highly prevalent. Factors related to the acute critical illness, intensive care unit practices such as heavy sedation, physical restraints and immobility as well as aging physiology and coexisting geriatric conditions can combine to result in these poor outcomes. Conclusion Older adults who survive critical illness suffer physical and cognitive declines resulting in disability at greater rates than hospitalized, non-critically ill and community dwelling older adults. Interventions derived from widely available geriatric care models in use outside of the ICU, which address modifiable risk factors including immobility and delirium, are associated with improved functional and cognitive outcomes and can be used to complement ICU-focused models such as the ABCDEs.

EPICO 4.0. 'Total quality' in the management of invasive candidiasis in critically ill patients by analysing the integrated process.

PubMed

Zaragoza, Rafael; Ferrer, Ricard; Llinares, Pedro; Maseda, Emilio; Rodríguez, Alejandro; Grau, Santiago; Quindós, Guillermo

A high quality integrated process in the clinical setting of non-neutropenic critically ill patients at risk for invasive candidiasis is a necessary tool to improve the management of these patients. To identify the key points on invasive candidiasis in order to develop a set of recommendations with a high level of consensus required for the creation of a total quality integrated process for the management of non-neutropenic critically ill patients at risk of invasive candidiasis. After a thorough review of the literature of the previous five years, a Spanish prospective questionnaire, which measured consensus by the Delphi technique, was anonymously conducted by e-mail, including 31 national multidisciplinary experts with extensive experience in invasive fungal infections, from six national scientific societies. The experts included a specialist in intensive care medicine, anesthetists, microbiologists, pharmacologists, and specialists in infectious diseases that responded 27 questions prepared by the coordination group. The educational objectives considered six processes that included knowledge of the local epidemiology, the creation and development of multidisciplinary teams, the definitions of the process, protocols, and indicators (KPI), an educational phase, hospital implementation, and the measurement of outcomes. The level of agreement among experts in each category to be selected should exceed 70%. In a second phase, after drawing up the recommendations of the selected processes, a face to face meeting with more than 60 specialists was held. The specialists were asked to validate the pre-selected recommendations. Firstly, 20 recommendations from all the sections were pre-selected: Knowledge of local epidemiology (3 recommendations), creation and development of multidisciplinary teams (3), definition of the process, protocols and indicators (1), educational phase (3), hospital implementation (3), and measurement of outcomes (7). After the second phase, 18 recommendations were validated, and it was concluded that the minimum team or core necessary for the development of an efficient program in the use of antifungal drugs in non-neutropenic critically ill patients must consist of a specialist in infectious diseases, a clinical pharmacist, a microbiologist, a specialist in intensive care medicine, a specialist in anesthesia and recovery, and an administrator or member of the medical management team, and, in order to be cost-effective, it should be implemented in hospitals with over 200 beds. In addition, it is recommended to apply a consensual check list for the evaluation of the diagnostic process and treatment of invasive candidiasis in patients that have started an antifungal treatment. The management of external knowledge and individual learning stand out as active educational strategies. The main strategies for measuring patient safety outcomes are the analysis of the results achieved, and learning activities; assess, review and refine the deployment of the processes; quality control; epidemiological surveillance and applied research; benchmarking; and basic research. The results of the integrated process should be annually disseminated outside the hospital. Optimizing the management of invasive candidiasis requires the application of the knowledge and skills detailed in our recommendations. These recommendations, based on the Delphi methodology, facilitate the creation of a total quality integrated process in critically-ill patients at risk for invasive candidiasis.

Evidence suggests that critically ill children develop muscle wasting, which could affect outcomes. Muscle ultrasound has been used to track muscle wasting and association with outcomes in critically ill adults but not children. This review aims to summarize methodological considerations of muscle ultrasound, structural findings, and possibilities for its application in the assessment of nutrition and functional outcomes in critically ill children. Medline, Embase, and CINAHL databases were searched up until April 2016. Articles describing skeletal muscle ultrasound in children and critically ill adults were analyzed qualitatively for details on techniques and findings. Thickness and cross-sectional area of various upper and lower body muscles have been studied to quantify muscle mass and detect muscle changes. The quadriceps femoris muscle is one of the most commonly measured muscles due to its relation to mobility and is sensitive to changes over time. However, the margin of error for quadriceps thickness is too wide to reliably detect muscle changes in critically ill children. Muscle size and its correlation with strength and function also have not yet been studied in critically ill children. Echogenicity, used to detect compromised muscle structure in neuromuscular disease, may be another property worth studying in critically ill children. Muscle ultrasound may be useful in detecting muscle wasting in critically ill children but has not been shown to be sufficiently reliable in this population. Further study of the reliability and correlation with functional outcomes and nutrition intake is required before muscle ultrasound is routinely employed in critically ill children.

Oral intake evaluation in patients following critical illness: an ICU cohort study.

Timely and adequate nutrition improves health outcomes for the critically ill patient. Despite clinical guidelines recommending early oral nutrition, survivors of critical illness experience significant nutritional deficits. This cohort study evaluates the oral nutrition intake in intensive care unit (ICU) patients who have experienced recent critical illness. The oral nutrition intake of a convenience sample of ICU patients post-critical illness was observed during a 1-month period. Data pertaining to both the amount of oral nutrition intake and factors impacting optimal oral nutrition intake were collected and analysed. Inadequate oral intake was identified in 62% of the 79 patients assessed (n = 49). This was noted early in the ICU stay, around day 1-2, for most of the patients. A significant proportion (25%) of patients remained in the hospital with poor oral intake that persisted beyond ICU day 5. Unsurprisingly, these were the patients who had longer ICU stays. Critical illness weakness was a factor in the assessment of poor oral intake. To conclude, patients who have experienced critical illness also experience suboptimal oral nutrition. The three key factors that were identified as impacting optimal oral nutrition were early removal of nasogastric tubes, critical illness weakness and poor appetite post-critical illness. Seven key recommendations are made based on this cohort study. These recommendations are related to patient assessment, monitoring, documentation and future guidelines. Future research opportunities are highlighted, including the investigation of strategies to improve the transition of patients' post-critical illness to oral nutrition. © 2018 British Association of Critical Care Nurses.

Overview of modern management of patients with critical injury and severe sepsis.

PubMed

Streat, S J; Plank, L D; Hill, G L

2000-06-01

Over the last 10 years there have been substantial changes in the issues confronting intensivists and surgeons caring for critically ill patients. A substantial increase in the number of elderly patients with surgical illness and complex co-morbidity has accompanied the increase in the proportion of elderly in populations in the developed world. This phenomenon has been seen particularly with sepsis. Incidence rates for blunt trauma have declined overall, but the problems of the elderly trauma patient have become more evident. Major elective surgery remains a common indication for short-term intensive care in many countries, but the need for cost-containment has led to increased use of high-dependency care for many such patients. Expectations of both society and clinicians have increased, and this has been reflected in the increased demand for complex procedures (e.g., liver transplantation, cerebral artery aneurysm clipping, aortic aneurysm repair) in patients previously considered at too high risk. Along with these expectations have come pressures on clinicians to reduce costs at the same time as improving clinical outcomes. Despite many advances in the care of critically ill patients with injury or sepsis, mortality, morbidity, and cost remain high; and nutritional support is frequently required. The duration and extent of the metabolic changes seen in response to critical surgical illness and intensive care treatments have become better characterized. Although some of the changes in body water and fat are modifiable, loss of large amounts of (functional) protein has been resistant to various strategies so far studied.

This editorial article examines what is meant by sex, gender and equity and argues that these are critical concepts to address in the effective management of communicable disease. Drawing on examples from the three major diseases of poverty (HIV, tuberculosis [TB] and malaria), the article explores how, for women and men, gender and poverty can lead to differences in vulnerability to illness; access to quality preventive and curative measures; and experience of the impact of ill health. This exploration sets the context for the three companion papers which outline how gender and poverty shape responses to the three key diseases of poverty in different geographical settings: HIV/AIDS in Kenya; TB in India; and malaria in Ghana.

Intensive care physicians should therefore know about basics in dysphagiology.

Approach to the critically ill camelid.

PubMed

Bedenice, Daniela

2009-07-01

The estimation of fluid deficits in camelids is challenging. However, early recognition and treatment of shock and hypovolemia is instrumental to improve morbidity and mortality of critically ill camelids. Early goal-directed fluid therapy requires specific knowledge of clinical indicators of hypovolemia and assessment of resuscitation endpoints, but may significantly enhance the understanding, monitoring, and safety of intravenous fluid therapy in South American camelids (SAC). It is important to recognize that over-aggressive fluid resuscitation is just as detrimental as under resuscitation. Nonetheless, a protocol of conservative fluid management is often indicated in the treatment of camelids with pulmonary inflammation, to counteract edema formation. The early recognition of lung dysfunction is often based on advanced diagnostic techniques, including arterial blood gas analysis, diagnostic imaging, and noninvasive pulmonary function testing.

Music is an ideal intervention to reduce anxiety and promote relaxation in critically ill patients. This article reviews the research studies on music-listening interventions to manage distressful symptoms in this population, and describes the development and implementation of the Music Assessment Tool (MAT) to assist professionals in ascertaining patients’ music preferences in the challenging, dynamic clinical environment of the intensive care unit (ICU). The MAT is easy to use with these patients who experience profound communication challenges due to fatigue and inability to speak because of endotracheal tube placement. The music therapist and ICU nursing staff are encouraged to work collaboratively to implement music in a personalized manner to ensure the greatest benefit for mechanically ventilated patients.

Hemodynamic monitoring offers valuable information on cardiovascular performance in the critically ill, and has become a fundamental tool in the diagnostic approach and in the therapy guidance of those patients presenting with tissue hypoperfusion. From introduction of the pulmonary artery catheter to the latest less invasive technologies, hemodynamic monitoring has been surrounded by many questions regarding its usefulness and its ultimate impact on patient prognosis. The Cardiological Intensive Care and CPR Working Group (GTCIC-RCP) of the Spanish Society of Intensive Care and Coronary Units (SEMICYUC) has recently impulsed the development of an updating series in hemodynamic monitoring. Now, a final series of recommendations are presented in order to analyze essential issues in hemodynamics, with the purpose of becoming a useful tool for residents and critical care practitioners involved in the daily management of critically ill patients.

2016-01-01

Purpose. Fluid therapy aimed at increasing urine output is a commonly employed strategy to prevent acute kidney injury (AKI) in critically ill patients with rhabdomyolysis. Automated fluid management has the potential to optimise urine output while avoiding fluid accumulation in rhabdomyolysis patients. Methods. In a single centre clinical service evaluation we compared a convenience sample of critically ill adults with rhabdomyolysis treated with automated fluid management using the RenalGuard® device to patients managed with manual fluid adjustment following our standard rhabdomyolysis protocol. Primary outcome was number of hours with urine output >2 mL/kg during first 48 h of therapy. Results. Eight patients treated with RenalGuard were compared to 28 patients treated with manual fluid management. Number of hours of target urine output was greater in the RenalGuard versus the Standard group (176/312 (56.4%) versus 534/1305 (40.9%); p < 0.01). Urine output was significantly higher in the first 24 h in the RenalGuard group (median (IQR) 4033 mL (3682–7363) versus 2913 mL (2263–4188 mL); p < 0.01). Fluid balance, electrolyte, diuretics, and bicarbonate use were comparable between groups. Conclusions. Automated fluid management resulted in a higher urine output more quickly in the treatment of rhabdomyolysis. Further research is needed to analyse the effect of diuresis-matched hydration for the prevention of AKI in rhabdomyolysis. PMID:28003911

Critical care medicine in the United States: addressing the intensivist shortage and image of the specialty.

PubMed

Halpern, Neil A; Pastores, Stephen M; Oropello, John M; Kvetan, Vladimir

2013-12-01

Intensivists are increasingly needed to care for the critically ill and manage ICUs as ICU beds, utilization, acuity of illness, complexity of care and costs continue to rise. However, there is a nationwide shortage of intensivists that has occurred despite years of well publicized warnings of an impending workforce crisis from specialty societies and the federal government. The magnitude of the intensivist shortfall, however, is difficult to determine because there are many perspectives of optimal ICU administration, patient coverage and intensivist availability and a lack of national data on intensivist practices. Nevertheless, the intensivist shortfall is quite real as evidenced by the alternative solutions that hospitals are deploying to provide care for their critically ill patients. In the midst of these manpower struggles, the critical care environment is dynamically changing and becoming more stressful. Severe hospital bed availability and fiscal constraints are forcing ICUs to alter their approaches to triage, throughput and unit staffing. National and local organizations are mandating that hospitals comply with resource intensive and arguably unproven initiatives to monitor and improve patient safety and quality, and informatics systems. Lastly, there is an ongoing sense of professional dissatisfaction among intensivists and a lack of public awareness that critical care medicine is even a distinct specialty. This article offers proposals to increase the adult intensivist workforce through expansion and enhancements of internal medicine based critical care training programs, incentives for recent graduates to enter the critical care medicine field, suggestions for improvements in the critical care profession and workplace to encourage senior intensivists to remain in the field, proactive marketing of critical care, and expanded engagement by the critical care societies in the challenges facing intensivists.

Tele-Pediatric Intensive Care for Critically Ill Children in Syria.

2017-12-12

Armed conflicts can result in humanitarian crises and have major impacts on civilians, of whom children represent a significant proportion. Usual pediatric medical care is often disrupted and trauma resulting from war-related injuries is often devastating. High pediatric mortality rates are thus experienced in these ravaged medical environments. Using simple communication technology to provide real-time management recommendations from highly trained pediatric personnel can provide substantive clinical support and have a significant impact on pediatric morbidity and mortality. We implemented a "Tele-Pediatric Intensive Care" program (Tele-PICU) to provide real-time management consultation for critically ill and injured pediatric patients in Syria with intensive care needs. Over the course of 7 months, 19 cases were evaluated, ranging in age from 1 day to 11 years. Consultation questions addressed a wide range of critical care needs. Five patients are known to have survived, three were transferred, five died, and six outcomes were unknown. Based on this limited undertaking with its positive impact on survival, further development of Tele-PICU-based efforts with attention to implementation and barriers identified through this program is desirable. Even limited Tele-PICU can provide timely and potentially lifesaving assistance to pediatric care providers. Future efforts are encouraged.

Hemophagocytic lymphohistiocytosis (HLH) comprises a heterogeneous group of diseases which are characterized by a hyperinflammatory state due to uncontrolled T cell, macrophage and histiocyte activation, accompanied by excessive cytokine production. This rare condition is almost uniformly fatal unless promptly recognized and treated. Much progress has been made in the last two decades in our understanding of the mechanisms underlying familial, and to a lesser extent, acquired cases of HLH. Recurrent mutations in more than 10 different genes have now been identified, involving biological pathways converging on intracellular vesicle trafficking, and cytolytic granule exocytosis. Mechanisms underlying the majority of acquired HLH cases, however, remain elusive, hampering both diagnostic evaluation as well as therapeutic management of these patients. Given that the majority of intensive care unit (ICU) patients with sepsis or multiorgan failure share many features of HLH, it is especially critical for pediatric and adult intensivists to be able to recognize patients with bona fide HLH and initiate treatment without delay. In this article, we review our current understanding of the pathophysiology, clinical testing, diagnosis, and treatment of patients with HLH, especially as it pertains to the care of critically ill patients in pediatric and medical ICUs.

For critically ill adult patients with acute traumatic brain injury (TBI), we assessed the clinical and cost-effectiveness of: (a) Management in dedicated neurocritical care units versus combined neuro/general critical care units within neuroscience centres. (b) 'Early' transfer to a neuroscience centre versus 'no or late' transfer for those who present at a non-neuroscience centre. The Risk Adjustment In Neurocritical care (RAIN) Study included prospective admissions following acute TBI to 67 UK adult critical care units during 2009-11. Data were collected on baseline case-mix, mortality, resource use, and at six months, Glasgow Outcome Scale Extended (GOSE), and quality of life (QOL) (EuroQol 5D-3L). We report incremental effectiveness, costs and cost per Quality-Adjusted Life Year (QALY) of the alternative care locations, adjusting for baseline differences with validated risk prediction models. We tested the robustness of results in sensitivity analyses. Dedicated neurocritical care unit patients (N = 1324) had similar six-month mortality, higher QOL (mean gain 0.048, 95% CI -0.002 to 0.099) and increased average costs compared with those managed in combined neuro/general units (N = 1341), with a lifetime cost per QALY gained of £14,000. 'Early' transfer to a neuroscience centre (N = 584) was associated with lower mortality (odds ratio 0.52, 0.34-0.80), higher QOL for survivors (mean gain 0.13, 0.032-0.225), but positive incremental costs (£15,001, £11,123 to £18,880) compared with 'late or no transfer' (N = 263). The lifetime cost per QALY gained for 'early' transfer was £11,000. For critically ill adult patients with acute TBI, within neuroscience centres management in dedicated neurocritical care units versus combined neuro/general units led to improved QoL and higher costs, on average, but these differences were not statistically significant. This study finds that 'early' transfer to a neuroscience centre is associated with reduced mortality, improvement in QOL and is cost-effective.

Nitrogen Balance and Protein Requirements for Critically Ill Older Patients.

PubMed

Dickerson, Roland N

2016-04-18

Critically ill older patients with sarcopenia experience greater morbidity and mortality than younger patients. It is anticipated that unabated protein catabolism would be detrimental for the critically ill older patient. Healthy older subjects experience a diminished response to protein supplementation when compared to their younger counterparts, but this anabolic resistance can be overcome by increasing protein intake. Preliminary evidence suggests that older patients may respond differently to protein intake than younger patients during critical illness as well. If sufficient protein intake is given, older patients can achieve a similar nitrogen accretion response as younger patients even during critical illness. However, there is concern among some clinicians that increasing protein intake in older patients during critical illness may lead to azotemia due to decreased renal functional reserve which may augment the propensity towards worsened renal function and worsened clinical outcomes. Current evidence regarding protein requirements, nitrogen balance, ureagenesis, and clinical outcomes during nutritional therapy for critically ill older patients is reviewed.

Cultural diversity: family path through terminal illness.

PubMed

Baider, L

2012-04-01

In trying to comprehend a culture and its ways of structuring the world, much can be learned from addressing the manner in which intimate family relationships are ordered and family crises channeled toward care. A family's experience with illness cannot be considered in isolation from the cultural milieu in which it occurs. Family adaptation to cancer diagnosis is a continuous motion between many critical strata--a fragile oscillation between hope and desperation. Processes for optimal functioning and the well-being of members are seen to vary over time, as challenges unfold and families evolve across the life cycle and illness trajectory. The manner in which the healthcare system and family manage illness and terminal care is a particularly helpful window into the cultural, religious and traditional values of every family in a particular society.

Children transferred from community hospitals lacking specialized pediatric care are more seriously ill than those presenting to pediatric centers. Pediatric consultation and adherence to management guidelines improve outcomes. The aims of the study were (1) to assess whether telemedicine consultation in critical situations is feasible and (2) to compare the impact of pediatric critical care medicine (PCCM) consultation via telemedicine versus telephone on community hospital adherence to resuscitation guidelines through a randomized controlled telemedicine trial. In situ, high-fidelity simulation scenarios of critically ill children presenting to a community hospital and progressing to cardiopulmonary arrest were performed. Scenarios were randomized to PCCM consultation via telephone (control) or telemedicine (intervention). Primary outcome measure was proportion of teams who successfully defibrillated in 180 seconds or less from presentation of pulseless ventricular tachycardia. The following 30 scenarios were completed: 15 control and 15 intervention. Only 11 (37%) of 30 teams, defibrillated in 180 seconds or less from presentation of pulseless ventricular tachycardia; control: 6 (40%) of 15 versus intervention: 5 (33%) of 15, P = 0.7. Request for or use of backboard during cardiopulmonary resuscitation occurred in 24 (80%) of 30 scenarios; control: 9 (60%) of 15 versus intervention: 15 (100%) of 15, P = 0.006. Request for or use of stepstool during cardiopulmonary resuscitation occurred in 6 (20%) of 30 scenarios; control: 1 (7%) of 15 versus intervention: 5 (33%) of 15, P = 0.07. This study demonstrates the feasibility of using telemedicine to support acute management of children who present to community hospitals. Neither study arm adhered to current resuscitation guidelines and telemedicine consultation with PCCM experts was not associated with improvement. However, further research on optimizing telemedicine impact on the quality of pediatric care at community hospitals is warranted.

To examine associations among blood pressure, personal and illness characteristics, illness perception and medication and self-management adherence among adults with hypertension in rural mainland China. Despite the high prevalence of hypertension in China, the control rate is only 20%. Identifying factors associated with blood pressure control is critical. Cross-sectional survey. Data were collected from 163 hypertensive adults in two rural villages in mainland China. Measures included a demographic questionnaire, the Chinese Illness-Perception Questionnaire-Revised, Medication Adherence Inventory and the Inventory of Adherence to Self-management. Height, weight and blood pressure were also measured using standard approaches. Hierarchical linear regression was used to assess the association between blood pressure and significant variables identified in bivariate analysis. The mean systolic pressure observed in this sample was147 mmHg and the diastolic mean was 81 mmHg. None of the variables analyzed were associated with systolic blood pressure. Gender, age and household annual income were associated with diastolic blood pressure, explaining 23% of the variance in the regression model. Illness coherence contributed an additional 2%. These findings suggest: (a) healthcare providers should focus on educating rural hypertensive adults about healthful diets and behaviors to manage hypertension, especially for those with high household income; (b) knowledge-based health education alone is not adequate; (c) illness perception may not be directly associated with blood pressure and; (d) the Chinese Illness-Perception Questionnaire-Revised and the Inventory of Adherence to Self-management require validation and potential revision for use with rural Chinese populations.

Elevated cardiac troponin (cTn) in the absence of acute coronary syndromes (ACS) is associated with increased mortality in critically ill patients. There are no evidence-based interventions that reduce mortality in this group. We performed a retrospective investigation of the Veterans Administration Inpatient Evaluation Center database to determine whether drugs used in ACS (β-blockers, aspirin, and statins) are associated with reduced mortality in critically ill patients. Thirty-day mortality was determined for non-ACS patients admitted to any Veterans Administration Intensive Care Unit between October 1, 2007, and September 30, 2008, adjusted for severity of illness. Troponin assay values were normalized across institutions. Multivariate analyses for 30-day mortality showed an odds ratio (OR) of 1.82 for patients with high cTn (P < 0.0001, cTn > 10% coefficient of variation) and 1.18 for intermediate cTn (P = 0.0021, cTn between lowest limit detectable and 10% coefficient of variation) compared with patients with no elevation, adjusting for severity of illness (n = 19,979). Logistic regression models showed that patients with no or intermediate elevations of cTn taking statins within 24 hours of cTn measurement had a lower mortality than patients not taking statins (OR, 0.66; 95% confidence interval [95% CI], 0.53-0.82; P = 0.0003), whereas patients with high cTn had a lower mortality if they were taking β-blockers or aspirin within 24 hours of cTn measurement compared to patients not taking β-blockers or aspirin (β-blockers: OR, 0.80; 95% CI, 0.68-0.94; P = 0.0077; aspirin: OR, 0.81;95% CI, 0.69-0.96; P = 0.0134). This retrospective study confirms an association between elevated troponin and outcomes in critically ill patients without ACS and identifies statins, β-blockers, and aspirin as potential outcome modifiers in a cTn-dependent manner.

Emergency management of the patient with cardiac disease is an important part of veterinary practice. Although the causes of cardiac disease may be diverse, the understanding of basic pathophysiology will enable the clinician to formulate a rational diagnostic and therapeutic plan. The veterinary clinician must be able to triage the emergency patient, assess the clinical condition, and provide appropriate therapy. Close monitoring of the critically ill patient is crucial to patient survival and will help tailor therapy.

Violent victimization of adult patients with severe mental illness: a systematic review

2014-01-01

The aims of this paper are to review data on the prevalence and correlates of violent victimization of persons with severe mental illness, to critically evaluate the literature, and to explore possible approaches for future research. PubMed/MEDLINE and PsycINFO databases were searched using several terms related to severe mental illness in successive combinations with terms describing victimization. The searches identified 34 studies. Nine epidemiological studies indicate that patients with severe mental illness are more likely to be violently victimized than other community members. Young age, comorbid substance use, and homelessness are risk factors for victimization. Victimized patients are more likely to engage in violent behavior than other members of the community. Violent victimization of persons with severe mental illness has long-term adverse consequences for the course of their illness, and further impairs the quality of lives of patients and their families. Victimization of persons with severe mental illness is a serious medical and social problem. Prevention and management of victimization should become a part of routine clinical care for patients with severe mental illness. PMID:25336958

This large population-based cohort study evaluated the association between certain critical illnesses and the incidence of newly diagnosed type 2 diabetes mellitus (T2DM) in Taiwan. Data were obtained from the Taiwan National Health Insurance Research Database. According to age, sex, and propensity score-matching, a cohort comprising 9528 patients with critical illness, including septicemia, septic shock, acute myocardial infarction (AMI), and stroke, and a control cohort of 9528 patients with no critical illness were identified. Cox proportional-hazard regression and competing-risk regression models were employed to evaluate the risk of developing T2DM. With the median follow-up periods (interquartile range) of 3.86 (1.64-6.93) and 5.12 (2.51-8.13) years for the patients in the critical illness and control cohorts, respectively, the risk of developing T2DM in the critical illness cohort was significantly higher than in the control cohort (adjusted hazard ratio, aHR = 1.32; 95% confidence interval, CI 1.16-1.50). In the multivariate competing-risk regression models, the aHR of T2DM was 1.58 (95% CI 1.45-1.72) in the critical illness cohort. Moreover, among the patients with these critical illnesses, those with septicemia or septic shock exhibited the highest risk of developing T2DM (aHR = 1.51, 95% CI 1.37-1.67), followed by AMI compared with the control cohort. Our results suggest that patients with certain critical illnesses are associated with a high risk of developing T2DM. Clinicians should be aware of this association and intensively screen for T2DM in patients following diagnosis of critical illness.

Critically ill patients are especially vulnerable to medication errors (ME) due to their severe clinical situation and the complexities of their management. To determine the frequency and characteristics of ME and identify shortcomings in the processes of medication management in an Intensive Care Unit. During a 3 months period, an observational prospective and randomized study was carried out in the ICU of a university hospital. Every step of patient's medication management (prescription, transcription, dispensation, preparation and administration) was evaluated by an external trained professional. Steps with higher frequency of ME and their therapeutic groups involved were identified. Medications errors were classified according to the National Coordinating Council for Medication Error Reporting and Prevention. In 52 of 124 patients evaluated, 66 ME were found in 194 drugs prescribed. In 34% of prescribed drugs, there was at least 1 ME during its use. Half of ME occurred during medication administration, mainly due to problems in infusion rates and schedule times. Antibacterial drugs had the highest rate of ME. We found a 34% rate of ME per drug prescribed, which is in concordance with international reports. The identification of those steps more prone to ME in the ICU, will allow the implementation of an intervention program to improve the quality and security of medication management.

Pathophysiology of the Gut and the Microbiome in the Host Response.

To describe and summarize the data supporting the gut as the motor driving critical illness and multiple organ dysfunction syndrome presented at the National Institute of Child Health and Human Development MODS Workshop (March 26-27, 2015). Summary of workshop keynote presentation. Not applicable. Presented by an expert in the field, the data assessing the role of gastrointestinal dysfunction driving critical illness were described with a focus on identifying knowledge gaps and research priorities. Summary of presentation and discussion supported and supplemented by relevant literature. The understanding of gut dysfunction in critical illness has evolved greatly over time, and the gut is now often considered as the "motor" of critical illness. The association of the gut with critical illness is supported by both animal models and clinical studies. Initially, the association between gut dysfunction and critical illness focused primarily on bacterial translocation into the bloodstream. However, that work has evolved to include other gut-derived products causing distant injury via other routes (e.g., lymphatics). Additionally, alterations in the gut epithelium may be associated with critical illness and influence outcomes. Gut epithelial apoptosis, intestinal hyperpermeability, and perturbations in the intestinal mucus layer have all been associated with critical illness. Finally, there is growing evidence that the intestinal microbiome plays a crucial role in mediating pathology in critical illness. Further research is needed to better understand the role of each of these mechanisms and their contribution to multiple organ dysfunction syndrome in children.

Nutritional support and the role of the stress response in critically ill children.

Joosten, Koen F M; Kerklaan, Dorian; Verbruggen, Sascha C A T

2016-05-01

Nutrition impacts outcome in critically ill children. Based on evolving neuro-endocrine, immunologic and metabolic alterations, three different phases can be proposed during the course of illness. The different phases each demand for tailored macronutrient intakes in critically ill children. Early enteral nutrition is associated with decreased morbidity and mortality, but several misconceptions concerning the provision of enteral nutrition prevent adequate intake. Parenteral nutrition in critically ill children is associated with potential disadvantages, as nosocomial infections, but evidence on the effect on clinical outcome is lacking. Nutrient restriction early during critical illness might be beneficial for short and long-term outcomes by decreasing the incidence of side-effects and possibly by amplifying the acute catabolic stress response and stimulating autophagy and muscle integrity. Higher caloric and protein intake via the enteral route are associated with higher 60-day survival, asking for a more aggressive feeding approach in subsequent phases. Understanding the stress response to critical illness and its phases is essential for nutritional recommendations in critically ill children. Although parenteral nutrient restriction during the acute phase might be beneficial, inclining requirements ask for a more aggressive approach during the stable and recovery phase to enable recovery, growth and catch-up growth.

Preventing severe hyperglycemia with insulin reduced the neuropathological alterations in frontal cortex during critical illness. We investigated the impact of increasing glucose load under normoglycemia on neurons and glial cells. Hyperinflammatory critically ill rabbits were randomized to fasting or combined parenteral nutrition containing progressively increasing amounts of glucose (low, intermediate, high) within the physiological range but with a similar amount of amino acids and lipids. In all groups, normoglycemia was maintained with insulin. On day 7, we studied the neuropathological alterations in frontal cortex neurons, astrocytes and microglia, and MnSOD as marker of oxidative stress. The percentage of damaged neurons was comparable among all critically ill and healthy rabbits. Critical illness induced an overall 1.8-fold increase in astrocyte density and activation status, largely irrespective of the nutritional intake. The percentage of microglia activation in critically ill rabbits was comparable with that in healthy rabbits, irrespective of glucose load. Likewise, MnSOD expression was comparable in critically ill and healthy rabbits without any clear impact of the nutritional interventions. During prolonged critical illness, increasing intravenous glucose infusion while strictly maintaining normoglycemia appeared safe for neuronal integrity and did not substantially affect glial cells in frontal cortex.

Sekeres, Mikkael A.; Stern, Theodore A.

2002-01-01

Background: In a general hospital, few clinical settings match the intensity of the intensive care unit (ICU) experience. Clinical rotations in ICUs elicit and emphasize the struggles house officers face on a daily basis throughout their training. Method: These struggles were recorded by hundreds of residents in a journal maintained in the Massachusetts General Hospital's Medical ICU for the past 20 years. We systematically reviewed these unsolicited entries to define and to illustrate how house officers respond to caring for terminally ill patients. The 3 overarching topics that surfaced repeatedly were assessment of terminally ill patients, reaction to their prognosis, and management of their disease or their eventual demise. Results: House officers record affective reactions and cognitive assessments to cope with the stress and dysfunction associated with the care of the critically ill and to facilitate their management of these patients. Journal entries by residents reveal a deep concern for the welfare of their patients, conflict about the technological advances and limitations of the system, and reflection on how involved physicians should become with their patients. Conclusion: House officer journal entries reflect a combination of newly gained medical knowledge and coping strategies in managing terminally ill patients. House officers also demonstrate a deep concern for the welfare of their patients. Insight from years of reflection from past house officers can help prepare trainees and residency programs for the breadth and intensity of the ICU experience and for work in clinical practice settings that follow completion of training.

Neutrophils in critical illness.

PubMed

McDonald, Braedon

2018-03-01

During critical illness, dramatic alterations in neutrophil biology are observed including abnormalities of granulopoeisis and lifespan, cell trafficking and antimicrobial effector functions. As a result, neutrophils transition from powerful antimicrobial protectors into dangerous mediators of tissue injury and organ dysfunction. In this article, the role of neutrophils in the pathogenesis of critical illness (sepsis, trauma, burns and others) will be explored, including pathological changes to neutrophil function during critical illness and the utility of monitoring aspects of the neutrophil phenotype as biomarkers for diagnosis and prognostication. Lastly, we review findings from clinical trials of therapies that target the harmful effects of neutrophils, providing a bench-to-bedside perspective on neutrophils in critical illness.

Chronic Wasting Disease

2007-01-01

Chronic wasting disease (CWD) is an always-fatal, neurological illness occurring in North American cervids (members of the deer family), including white-tailed deer, mule deer, elk and moose. Since its discovery in 1967, CWD has spread geographically and increased in prevalence locally. CWD is contagious; it can be transmitted freely within and among free-ranging populations. It is likely that diseased animals can transmit CWD to healthy animals long before they become clinically ill. Managing CWD in free-ranging populations is extremely difficult, therefore preventative measures designed to reduce the chance for disease spread are critically important.

Prader-Willi Syndrome (PWS) is a genetic condition that results in a constellation of symptoms and typically results in hyperphagia and obesity in adulthood. Critically ill adults with PWS present a unique challenge to the nutrition professional, particularly when they require support modalities such as extracorporeal membrane oxygenation (ECMO). The purpose of this case study is to review the nutrition care of a critically ill adult patient with PWS who required venovenous ECMO. The patient was successfully managed with a hypocaloric, high-protein approach, which did not result in the diagnosis of malnutrition during his hospitalization. The patient was ultimately transitioned off extracorporeal life support and discharged to a rehabilitation facility. © 2018 American Society for Parenteral and Enteral Nutrition.

'Intensive care unit survivorship' - a constructivist grounded theory of surviving critical illness.

To theorise intensive care unit survivorship after a critical illness based on longitudinal qualitative data. Increasingly, patients survive episodes of critical illness. However, the short- and long-term impact of critical illness includes physical, psychological, social and economic challenges long after hospital discharge. An appreciation is emerging that care needs to extend beyond critical illness to enable patients to reclaim their lives postdischarge with the term 'survivorship' being increasingly used in this context. What constitutes critical illness survivorship has, to date, not been theoretically explored. Longitudinal qualitative and constructivist grounded theory. Interviews (n = 46) with 17 participants were conducted at four time points: (1) before discharge from hospital, (2) four to six weeks postdischarge, (3) six months and (4) 12 months postdischarge across two adult intensive care unit setting. Individual face-to-face interviews. Data analysis followed the principles of Charmaz's constructivist grounded theory. 'Intensive care unit survivorship' emerged as the core category and was theorised using concepts such as status passages, liminality and temporality to understand the various transitions participants made postcritical illness. Intensive care unit survivorship describes the unscheduled status passage of falling critically ill and being taken to the threshold of life and the journey to a life postcritical illness. Surviving critical illness goes beyond recovery; surviving means 'moving on' to life postcritical illness. 'Moving on' incorporates a redefinition of self that incorporates any lingering intensive care unit legacies and being in control of one's life again. For healthcare professionals and policymakers, it is important to realise that recovery and transitioning through to survivorship happen within an individual's time frame, not a schedule imposed by the healthcare system. Currently, there are no care pathways or policies in place for critical illness survivors that would support intensive care unit survivors and their families in the transitions to survivorship. © 2016 John Wiley & Sons Ltd.

The relationship between critical illness and psychiatric illness is unclear. To assess psychiatric diagnoses and medication prescriptions before and after critical illness. Population-based cohort study in Denmark of critically ill patients in 2006-2008 with follow-up through 2009, and 2 matched comparison cohorts from hospitalized patients and from the general population. Critical illness defined as intensive care unit admission with mechanical ventilation. Adjusted prevalence ratios (PRs) of psychiatrist-diagnosed psychiatric illnesses and prescriptions for psychoactive medications in the 5 years before critical illness. For patients with no psychiatric history, quarterly cumulative incidence (risk) and adjusted hazard ratios (HRs) for diagnoses and medications in the following year, using Cox regression. Among 24,179 critically ill patients, 6.2% had 1 or more psychiatric diagnoses in the prior 5 years vs 5.4% for hospitalized patients (adjusted PR, 1.31; 95% CI, 1.22-1.42; P<.001) and 2.4% for the general population (adjusted PR, 2.57; 95% CI, 2.41-2.73; P<.001). Five-year preadmission psychoactive prescription rates were similar to hospitalized patients: 48.7% vs 48.8% (adjusted PR, 0.97; 95% CI, 0.95-0.99; P<.001) but were higher than the general population (33.2%; adjusted PR, 1.40; 95% CI, 1.38-1.42; P<.001). Among the 9912 critical illness survivors with no psychiatric history, the absolute risk of new psychiatric diagnoses was low but higher than hospitalized patients: 0.5% vs 0.2% over the first 3 months (adjusted HR, 3.42; 95% CI, 1.96-5.99; P <.001), and the general population cohort (0.02%; adjusted HR, 21.77; 95% CI, 9.23-51.36; P<.001). Risk of new psychoactive medication prescriptions was also increased in the first 3 months: 12.7% vs 5.0% for the hospital cohort (adjusted HR, 2.45; 95% CI, 2.19-2.74; P<.001) and 0.7% for the general population (adjusted HR, 21.09; 95% CI, 17.92-24.82; P<.001). These differences had largely resolved by 9 to 12 months after discharge. Prior psychiatric diagnoses are more common in critically ill patients than in hospital and general population cohorts. Among survivors of critical illness, new psychiatric diagnoses and psychoactive medication use is increased in the months after discharge. Our data suggest both a possible role of psychiatric disease in predisposing patients to critical illness and an increased but transient risk of new psychiatric diagnoses and treatment after critical illness.

Identification of critically ill patients during prehospital care could facilitate early treatment and aid in the regionalization of critical care. Tools to consistently identify those in the field with or at higher risk of developing critical illness do not exist. We sought to validate a prehospital critical illness risk score that uses objective clinical variables in a contemporary cohort of geographically and temporally distinct prehospital encounters. We linked prehospital encounters at 21 emergency medical services (EMS) agencies to inpatient electronic health records at nine hospitals in southwestern Pennsylvania from 2010 to 2012. The primary outcome was critical illness during hospitalization, defined as an intensive care unit stay with delivery of organ support (mechanical ventilation or vasopressor use). We calculated the prehospital risk score using demographics and first vital signs from eligible EMS encounters, and we tested the association between score variables and critical illness using multivariable logistic regression. Discrimination was assessed using the AUROC curve, and calibration was determined by plotting observed versus expected events across score values. Operating characteristics were calculated at score thresholds. Among 42,550 nontrauma, non-cardiac arrest adult EMS patients, 1926 (4.5 %) developed critical illness during hospitalization. We observed moderate discrimination of the prehospital critical illness risk score (AUROC 0.73, 95 % CI 0.72-0.74) and adequate calibration based on observed versus expected plots. At a score threshold of 2, sensitivity was 0.63 (95 % CI 0.61-0.75), specificity was 0.73 (95 % CI 0.72-0.73), negative predictive value was 0.98 (95 % CI 0.98-0.98), and positive predictive value was 0.10 (95 % CI 0.09-0.10). The risk score performance was greater with alternative definitions of critical illness, including in-hospital mortality (AUROC 0.77, 95 % CI 0.7 -0.78). In an external validation cohort, a prehospital risk score using objective clinical data had moderate discrimination for critical illness during hospitalization.

Objective To describe and summarize the data supporting the “gut” as the motor driving critical illness and multiple organ dysfunction syndrome (MODS) presented at the Eunice Kennedy Shriver National Institute of Child Health and Human Development MODS Workshop (March 26–27, 2015). Data Sources Summary of workshop keynote presentation. Study Selection Not applicable. Data Extraction Presented by an expert in the field, the data assessing the role of gastrointestinal dysfunction driving critical illness were described with a focus on identifying knowledge gaps and research priorities. Data Synthesis Summary of presentation and discussion supported and supplemented by relevant literature. Conclusions The understanding of gut dysfunction in critical illness has evolved greatly over time, and the gut is now often considered as the “motor” of critical illness. The association of the gut with critical illness is supported by both animal models and clinical studies. Initially, the association between gut dysfunction and critical illness focused primarily on bacterial translocation into the bloodstream. However, that work has evolved to include other gut-derived products causing distant injury via other routes (e.g. lymphatics). Additionally, alterations in the gut epithelium may be associated with critical illness and influence outcomes. Gut epithelial apoptosis, intestinal hyperpermeability and perturbations in the intestinal mucus layer have all been associated with critical illness. Finally, there is growing evidence that the intestinal microbiome plays a crucial role in mediating pathology in critical illness. Further research is needed to better understand the role of each of these mechanisms and their contribution to MODS in children. PMID:28248833

Clinical review: SARS - lessons in disaster management.

Disaster management plans have traditionally been required to manage major traumatic events that create a large number of victims. Infectious diseases, whether they be natural (e.g. SARS [severe acute respiratory syndrome] and influenza) or the result of bioterrorism, have the potential to create a large influx of critically ill into our already strained hospital systems. With proper planning, hospitals, health care workers and our health care systems can be better prepared to deal with such an eventuality. This review explores the Toronto critical care experience of coping in the SARS outbreak disaster. Our health care system and, in particular, our critical care system were unprepared for this event, and as a result the impact that SARS had was worse than it could have been. Nonetheless, we were able to organize a response rapidly during the outbreak. By describing our successes and failures, we hope to help others to learn and avoid the problems we encountered as they develop their own disaster management plans in anticipation of similar future situations.

Hensley, Melissa Anne

2011-01-01

The purpose of this study was to examine the experiences and opinions of community-based mental health case managers with the Medicare prescription drug benefit. A qualitative approach, consisting of analysis of data from 3 case manager focus groups, was used to achieve an understanding of the role that case managers played in beneficiaries' access to and use of prescription medicines. Two urban nonprofit community-based mental health agencies. Adults who are disabled by mental illness depend on case managers for information about their prescription drug insurance, help with formulary and plan switching information, and assistance with tasks related to medication adherence in the community. Common themes in the case managers' discussion were managing beneficiary problems, stress for beneficiaries, information and paperwork issues, and cynicism regarding health care reform. The critical role of case managers in the use of Medicare Part D is not well understood or appreciated. Case managers need to be informed about Medicare Part D and ready to advocate for their clients in the community. In addition, it is important for case managers to understand how Medicare Part D affects not only older adults, but also adults living with serious and persistent mental illness.

Design Considerations for Post-Acute Care mHealth: Patient Perspectives.

PubMed

Sanger, Patrick; Hartzler, Andrea; Lober, William B; Evans, Heather L; Pratt, Wanda

2014-01-01

Many current mobile health applications ("apps") and most previous research have been directed at management of chronic illnesses. However, little is known about patient preferences and design considerations for apps intended to help in a post-acute setting. Our team is developing an mHealth platform to engage patients in wound tracking to identify and manage surgical site infections (SSI) after hospital discharge. Post-discharge SSIs are a major source of morbidity and expense, and occur at a critical care transition when patients are physically and emotionally stressed. Through interviews with surgical patients who experienced SSI, we derived design considerations for such a post-acute care app. Key design qualities include: meeting basic accessibility, usability and security needs; encouraging patient-centeredness; facilitating better, more predictable communication; and supporting personalized management by providers. We illustrate our application of these guiding design considerations and propose a new framework for mHealth design based on illness duration and intensity.

Thyroid storm. A review of cases at University of California, San Francisco.

PubMed

Roizen, M; Becker, C E

1971-10-01

Retrospective study of the diagnosis and management of the 8 cases of thyroid storm in a series of 400 hyperthyroid patients led to conclusion that thyroid storm is a clinical diagnosis based on a life-endangering illness in a hyperthyroid patient whose hyperthyroidism has been severely exacerbated by a serious precipitating illness, and that storm is manifest by the symptoms of hyperpyrexia, tachycardia and striking alterations in consciousness. No laboratory tests were diagnostic of storm, and the underlying precipitating cause of thyroid storm was the major determinant of survival. Vigorous therapy must include blocking synthesis of thyroid hormones with antithyroid drugs, blocking release of preformed hormone with iodine, meticulous attention to hydration and supportive therapy, as well as correction of precipitating cause of storm. The blocking of the sympathetic nervous system with reserpine or guanethidine or with alpha and beta blocking drugs may be exceedingly hazardous and requires skillful management and constant monitoring in a critically ill patient.

Intensive Care Management of Patients with Cirrhosis.

Olson, Jody C

2018-06-01

Cirrhosis is a major worldwide health problem which results in a high level of morbidity and mortality. Patients with cirrhosis who require intensive care support have high mortality rates of near 50%. The goal of this review is to address the management of common complications of cirrhosis in the ICU. Recent epidemiological studies have shown an increase in hospitalizations due to advanced liver disease with an associated increase in intensive care utilization. Given an increasing burden on the healthcare system, it is imperative that we strive to improve our management cirrhotic patients in the intensive care unit. Large studies evaluating the management of patients in the intensive care setting are lacking. To date, most recommendations are based on extrapolation of data from studies in cirrhosis outside of the ICU or by applying general critical care principles which may or may not be appropriate for the critically ill cirrhotic patient. Future research is required to answer important management questions.

2015-12-14

Levofloxacin is commonly used in critically ill patients for which existing data suggest nonstandard dosing regimens should be used. The objective of this study was to compare the population pharmacokinetics of levofloxacin in critically ill and in non-critically ill patients. Adult patients with a clinical indication for levofloxacin were eligible for participation in this prospective pharmacokinetic study. Patients were given 500 mg or 750 mg daily by intravenous administration with up to 11 blood samples taken on day 1 or 2 of therapy. Plasma samples were analyzed and population pharmacokinetic analysis was undertaken using Pmetrics. Thirty-five patients (18 critically ill) were included. The mean (standard deviation [SD]) age, weight, and Cockcroft-Gault creatinine clearance for the critically ill and for the non-critically ill patients were 60.3 (16.4) and 72.0 (11.6) years, 78.5 (14.8) and 70.9 (15.8) kg, and 71.9 (65.8) and 68.2 (30.1) ml/min, respectively. A two-compartment linear model best described the data. Increasing creatinine clearance was the only covariate associated with increasing drug clearance. The presence of critical illness did not significantly affect any pharmacokinetic parameter. The mean (SD) parameter estimates were as follows: clearance, 8.66 (3.85) liters/h; volume of the central compartment (Vc), 41.5 (24.5) liters; intercompartmental clearance constants from central to peripheral, 2.58 (3.51) liters/h; and peripheral to central compartments, 0.90 (0.58) liters/h. Monte Carlo dosing simulations demonstrated that achievement of therapeutic exposures was dependent on renal function, pathogen, and MIC. Critical illness appears to have no independent effect on levofloxacin pharmacokinetics that cannot be explained by altered renal function. Copyright © 2016, American Society for Microbiology.

To consolidate pediatric intensivists' understanding of the pathophysiology, definition, incidence, monitoring, and management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS); and to highlight the characteristics related to the pediatric population. This is a narrative review article that utilized a systematic search of the medical literature published in the English language between January 1990 and august 2016. Studies were identified by conducting a comprehensive search of Pub Med databases. Search terms included "intra-abdominal hypertension and child", "intra-abdominal hypertension and pediatrics", "abdominal compartment syndrome and child", and "abdominal compartment syndrome and pediatrics". Intra-abdominal hypertension and ACS are associated with a number of pathophysiological disturbances and increased morbidity and mortality. These conditions have been well described in critically ill adults. In children, the IAH and the ACS have a reported incidence of 13% and 0.6 to 10% respectively; they carry similar prognostic impact but are still under-diagnosed and under-recognized by pediatric health care providers. Intra-abdominal hypertension and ACS are conditions that are regularly encountered in critically ill children. They are associated with an increased morbidity and mortality. Early recognition, prevention and timely management of this critical condition are necessary to improve its outcome. Copyright © 2017 Elsevier Inc. All rights reserved.

OBJECTIVE To describe the state of glycemic control in non-critically ill diabetic patients admitted to the PR University Hospital, and the adherence to current standard of care guidelines for the treatment of diabetes. METHODS This was a retrospective study of patients admitted to a General Medicine ward with Diabetes Mellitus as a secondary diagnosis. Clinical data was analyzed for the first 5 days and the last 24 hours of admission. RESULTS One hundred and forty-seven (147) non-critically ill diabetic patients were evaluated. The rate of hyperglycemia and hypoglycemia was 56.7% and 2.8%, respectively. Nearly 60% of patients were hyperglycemic during the first 24 hrs of admission and 54.2% during the last 24 hrs. Mean last glucose value before discharge was 189.6 ± 73 mg/dL. Most patients were treated with subcutaneous insulin with basal insulin alone used as the most common regimen. The proportion of patients classified as uncontrolled receiving basal-bolus therapy increased from 54.3% on day 1 to 60.0% on day 5, with still 40.0% receiving only basal insulin. Most of the uncontrolled patients had their insulin dose increased (70.1%), however, a substantial portion had no change (23.7%) or even had a decrease (6.2%) in their insulin dose. CONCLUSIONS Even though there are areas of improvement in the management of hospitalized diabetic patients, it is still suboptimal, probably due to clinical inertia. A comprehensive educational diabetes management program, along with standardized insulin orders should be implemented to improve the care of these patients. PMID:24325996

This study aimed to determine hypoglycemia incidence and associated factors in critically ill patients. It looked at a retrospective cohort with 106 critically ill adult patients with 48 hours of glycaemic control and 72 hours of follow up. The dependent variable, hypoglycaemia (≤70 mg/dl), was assessed with respect to independent variables: age, diet, insulin, catecholamines, haemodialysis, nursing workload and the Simplified Acute Physiology Score. Statistical analysis was performed using Student's t-test, Fisher's exact test and logistic regression at 5% significance level. Incidence of hypoglycaemia was 14.2%. Hypoglycaemia was higher in the group of patients on catecholamines (p=0.040), with higher glycaemic variability (p<0.001) and death in the intensive care unit (p=0.008). Risk factors were identified as absence of oral diet (OR 5.11; 95% CI 1.04-25.10) and haemodialysis (OR 4.28; 95% CI 1.16-15.76). Patients on haemodialysis and with no oral diet should have their glycaemic control intensified in order to prevent and/or manage hypoglycaemic episodes.

Do sedation and analgesia contribute to long-term cognitive dysfunction in critical care survivors?

Fernandez-Gonzalo, S; Turon, M; De Haro, C; López-Aguilar, J; Jodar, M; Blanch, L

2018-03-01

Deep sedation during stay in the Intensive Care Unit (ICU) may have deleterious effects upon the clinical and cognitive outcomes of critically ill patients undergoing mechanical ventilation. Over the last decade a vast body of literature has been generated regarding different sedation strategies, with the aim of reducing the levels of sedation in critically ill patients. There has also been a growing interest in acute brain dysfunction, or delirium, in the ICU. However, the effect of sedation during ICU stay upon long-term cognitive deficits in ICU survivors remains unclear. Strategies for reducing sedation levels in the ICU do not seem to be associated with worse cognitive and psychological status among ICU survivors. Sedation strategy and management efforts therefore should seek to secure the best possible state in the mechanically ventilated patient and lower the prevalence of delirium, in order to prevent long-term cognitive alterations.

Despite the advances in critical care medicine, the hospital mortality in patients with acute kidney injury (AKI) requiring dialysis remains high. Depending on the underlying disease the in-house mortality is reported to be up to 80%. Several observational studies demonstrated an association between mortality and fluid overload. A primary mechanism of interest is that fluid overload causes tissue edema and subsequent reduction of perfusion, oxygenation and nutrient delivery. This results in further renal damage. In addition, fluid overload-related dilution within the extracellular space causes artificially low serum creatinine, which masks AKI diagnosis. As a consequence, renal protective management strategies are deferred, which further aggravates kidney injury. This aggravation of renal damage subsequently increases the mortality. This review discusses the role of fluid overload for outcomes in critically ill patients as described in the current literature and assesses criteria for the initiation of renal replacement therapy in this critically ill population. © Georg Thieme Verlag KG Stuttgart · New York.

Sleep Deprivation in Critical Illness: Its Role in Physical and Psychological Recovery

2012-01-01

Critically ill patients frequently experience poor sleep, characterized by frequent disruptions, loss of circadian rhythms, and a paucity of time spent in restorative sleep stages. Factors that are associated with sleep disruption in the intensive care unit (ICU) include patient-ventilator dysynchrony, medications, patient care interactions, and environmental noise and light. As the field of critical care increasingly focuses on patients' physical and psychological outcomes following critical illness, understanding the potential contribution of ICU-related sleep disruption on patient recovery is an important area of investigation. This review article summarizes the literature regarding sleep architecture and measurement in the critically ill, causes of ICU sleep fragmentation, and potential implications of ICU-related sleep disruption on patients' recovery from critical illness. With this background information, strategies to optimize sleep in the ICU are also discussed. PMID:21220271

BACKGROUND Early ambulatory palliative care (PC) is an emerging practice, and its key elements have not been defined. We conducted a qualitative analysis of data from a randomized controlled trial that demonstrated improved quality of life, mood, and survival in patients with newly diagnosed metastatic non-small cell lung cancer who received early PC integrated with standard oncologic care vs standard oncologic care alone. Our objectives were to (1) identify key elements of early PC clinic visits, (2) explore the timing of key elements, and (3) compare the content of PC and oncologic visit notes at the critical time points of clinical deterioration and radiographic disease progression. METHODS We randomly selected 20 patients who received early PC and survived within 4 periods: less than 3 months (n = 5), 3 to 6 months (n = 5), 6 to 12 months (n = 5), and 12 to 24 months (n = 5). We performed content analysis on PC and oncologic visit notes from the electronic health records of these patients. RESULTS Addressing symptoms and coping were the most prevalent components of the PC clinic visits. Initial visits focused on building relationships and rapport with patients and their families and on illness understanding, including prognostic awareness. Discussions about resuscitation preferences and hospice predominantly occurred during later visits. Comparing PC and oncologic care visits around critical time points, both included discussions about symptoms and illness status; however, PC visits emphasized psychosocial elements, such as coping, whereas oncologic care visits focused on cancer treatment and management of medical complications. CONCLUSIONS Early PC clinic visits emphasize managing symptoms, strengthening coping, and cultivating illness understanding and prognostic awareness in a responsive and time-sensitive model. During critical clinical time points, PC and oncologic care visits have distinct features that suggest a key role for PC involvement and enable oncologists to focus on cancer treatment and managing medical complications.

Shared decision-making has become the standard of care for most medical treatments. However, little is known about physician communication practices in the decision making for unstable critically ill patients with known end-stage disease. To describe communication practices of physicians making treatment decisions for unstable critically ill patients with end-stage cancer, using the framework of shared decision-making. Analysis of audiotaped encounters between physicians and a standardized patient, in a high-fidelity simulation scenario, to identify best practice communication behaviors. The simulation depicted a 78-year-old man with metastatic gastric cancer, life-threatening hypoxia, and stable preferences to avoid intensive care unit (ICU) admission and intubation. Blinded coders assessed the encounters for verbal communication behaviors associated with handling emotions and discussion of end-of-life goals. We calculated a score for skill at handling emotions (0-6) and at discussing end of life goals (0-16). Twenty-seven hospital-based physicians. Independent variables included physician demographics and communication behaviors. We used treatment decisions (ICU admission and initiation of palliation) as a proxy for accurate identification of patient preferences. Eight physicians admitted the patient to the ICU, and 16 initiated palliation. Physicians varied, but on average demonstrated low skill at handling emotions (mean, 0.7) and moderate skill at discussing end-of-life goals (mean, 7.4). We found that skill at discussing end-of-life goals was associated with initiation of palliation (p = 0.04). It is possible to analyze the decision making of physicians managing unstable critically ill patients with end-stage cancer using the framework of shared decision-making.

The potential role of nano- and micro-technology in the management of critical illnesses.

PubMed

Sadikot, Ruxana T

2014-11-20

In recent years nanomedicine has become an attractive concept for the targeted delivery of therapeutic and diagnostic compounds to injured or inflamed organs. Nanoscale drug delivery systems have the ability to improve the pharmacokinetics and increase the biodistribution of therapeutic agents to target organs, thereby resulting in improved efficacy and reduced drug toxicity. These systems are exploited for therapeutic purposes to carry the drug in the body in a controlled manner from the site of administration to the therapeutic target. The mortality in many of the critical illnesses such as sepsis and acute respiratory distress syndrome continues to remain high despite of an increased understanding of the molecular pathogenesis of these diseases. Several promising targets that have been identified as potential therapies for these devastating diseases have been limited because of difficulty with delivery systems. In particular, delivery of peptides, proteins, and miRNAs to the lung is an ongoing challenge. Hence, it is an attractive strategy to test potential targets by employing nanotechnology. Here some of the novel nanomedicine approaches that have been proposed and studied in recent years to facilitate the delivery of therapeutic agents in the setting of critical illnesses such as acute respiratory distress syndrome, sepsis and ventilator associated pneumonia are reviewed.

Clinical review: Critical illness polyneuropathy and myopathy

2008-01-01

Critical illness polyneuropathy (CIP) and myopathy (CIM) are major complications of severe critical illness and its management. CIP/CIM prolongs weaning from mechanical ventilation and physical rehabilitation since both limb and respiratory muscles can be affected. Among many risk factors implicated, sepsis, systemic inflammatory response syndrome, and multiple organ failure appear to play a crucial role in CIP/CIM. This review focuses on epidemiology, diagnostic challenges, the current understanding of pathophysiology, risk factors, important clinical consequences, and potential interventions to reduce the incidence of CIP/CIM. CIP/CIM is associated with increased hospital and intensive care unit (ICU) stays and increased mortality rates. Recently, it was shown in a single centre that intensive insulin therapy significantly reduced the electrophysiological incidence of CIP/CIM and the need for prolonged mechanical ventilation in patients in a medical or surgical ICU for at least 1 week. The electrophysiological diagnosis was limited by the fact that muscle membrane inexcitability was not detected. These results have yet to be confirmed in a larger patient population. One of the main risks of this therapy is hypoglycemia. Also, conflicting evidence concerning the neuromuscular effects of corticosteroids exists. A systematic review of the available literature on the optimal approach for preventing CIP/CIM seems warranted. PMID:19040777

Foodborne illness: new developments concerning an old problem.

PubMed

Kasowski, Eric J; Gackstetter, Gary D; Sharp, Trueman W

2002-08-01

Foodborne illnesses continue to cause substantial morbidity and mortality in the United States, primarily as gastroenteritis but occasionally as other syndromes as well. Most of these illnesses are caused by a variety of widely known infectious agents, principally viruses, and are probably the result of common mistakes in food handling in the home or in restaurants. The epidemiology of foodborne illness is evolving. Major changes in food production, distribution, and consumption have created opportunities for new pathogens to emerge and for old ones to reemerge, and the potential for widespread outbreaks is increasing. Antibiotic resistance in bacterial pathogens resulting from the widespread use of antimicrobial agents in animal husbandry is also an important concern. Clinicians must be aware of the changing epidemiology of foodborne illness to recognize and manage these conditions in the clinical setting. In addition, clinicians are critical in the reporting of recognized or suspected foodborne illness, so that public health authorities are able to investigate, understand, and ultimately better control them. A number of new techniques have been employed, and others under development will improve our ability to recognize and cope with foodborne diseases.

Infections and infectious complications are the major cause of morbidity and mortality in febrile neutropenic patients after autologous stem cell transplantation. Laboratory biomarkers are helpful for early identification of critically ill patients and optimal therapy management. Several studies in adult non-neutropenic patients proposed sTREM-1 as a superior biomarker for identification of septic patients as well as a predictor for survival in these patients compared with procalcitonin (PCT), C-reactive protein (CRP), or interleukin-8 (IL-8). Here, to assess the utility of PCT, CRP, IL-8, and sTREM-1 in febrile neutropenia, 44 patients presenting with febrile neutropenia after autologous stem cell transplantation were recruited in a single-center prospective pilot study. We analyzed PCT and CRP as well as IL-8 and sTREM-1 levels pre- and post-transplantation at defined time points. In 20 of 44 patients, concentration of sTREM-1 was under the detection level at appearance of febrile neutropenia. Mean levels of PCT, IL-8, and CRP were significantly increased in infections of critically ill patients who by dysfunction or failure of one or more organs/system depend on survival from advanced instruments of monitoring and therapy. However, all tested biomarkers could not distinguish between presence and absence of bloodstream infection. The combination of the biomarkers PCT and IL-8 achieved a high sensitivity of 90% and specificity of 74% for the identification of serious complications in febrile neutropenia, whereas the combination of CRP and PCT or IL-8 achieved a high sensitivity of 100%, but with the addition of a low specificity of 47or 41%. In conclusion, we found that the measurement of sTREM-1 concentration at presentation of febrile neutropenia is not useful to identify bacterial bloodstream infections and critically ill patients. PCT and IL-8 are useful biomarkers for the early identification of critically ill patients, compared to CRP and sTREM-1 in febrile neutropenia. PCT or IL-8 in combination with clinical parameters should be considered in routine measurement to identify critically ill patients as early as possible.

The effective management of patients with chronic illnesses is critical to bending the curve of health care spending in the United States and is a crucial test for health care reform. In this article we used data from three national surveys of physician practices between 2006 and 2013 to determine the extent to which practices of all sizes have increased their use of evidence-based care management processes associated with patient-centered medical homes for patients with asthma, congestive heart failure, depression, and diabetes. We found relatively large increases over time in the overall use of these processes for small and medium-size practices as well as for large practices. However, the large practices used fewer than half of the recommended processes, on average. We also identified the individual processes whose use increased the most and show that greater use of care management processes is positively associated with public reporting of patient experience and clinical quality and with pay-for-performance.

Background/Methods Sedation management, delirium monitoring, and mobility programs are key features of recent evidence-based critical care guidelines and care bundles, yet implementation in the intensive care unit (ICU) remains highly variable. The Institute for Healthcare Improvement’s Rethinking Critical Care (IHI-RCC) program was established to reduce harm of critically ill patients by decreasing sedation, increasing monitoring and management of delirium, and increasing patient mobility. It involved one live case study and five iterations of an in-person seminar over 33 months (March 2011 to November 2013) that emphasized interdisciplinary teamwork and culture change. IHI-RCC has involved over 650 participants from 215 organizations. This report describes a convenience sample of five participating organizations chosen in advance of knowing their clinical outcomes. Results Qualitative descriptions of the changes tested at each of the five case study sites are provided, demonstrating the necessary teamwork, improved processes, and increased reliability of daily work. These sites all worked to implement the Richmond Agitation Sedation Scale (RASS) and Confusion Assessment Method for the ICU (CAM-ICU) within the context of a bundled interventional care plan; they then tracked length of stay in the ICU and duration of mechanical ventilation, which are reported. Discussion Changing critical care practices requires an interdisciplinary approach addressing cultural, psychological, and practical issues. The IHI-RCC program is based on testing changes on a small scale, building highly effective interdisciplinary rounds, frequent data feedback to the frontline, and use of in-person demonstrations. Key lessons are emerging about effectively caring for critically ill patients in light of data about the harm of over-sedation, unrecognized and unaddressed delirium, and immobility. PMID:25976892

Children who are critically ill are frequently viewed as "too sick" to tolerate physical activity. As a result, these children often fail to develop strength or cardiovascular endurance as compared to typically developing children. Previous reports have shown that early participation in physical activity in is safe and feasible for patients who are critically ill and may result in a shorter length of stay and improved functional outcomes. The use of the virtual reality gaming systems has become a popular form of therapy for children with disabilities and has been supported by a growing body of evidence substantiating its effectiveness with this population. The use of the virtual reality gaming systems in pediatric rehabilitation provides the children with opportunity to participate in an exercise program that is fun, enjoyable, playful, and at the same time beneficial. The integration of those systems in rehabilitation of children who are critically ill is appealing and has the potential to offer the possibility of enhancing physical activities. The lack of training studies involving children who are critically ill makes it difficult to set guidelines on the recommended physical activities and virtual reality gaming systems that is needed to confer health benefits. Several considerations should be taken into account before recommended virtual reality gaming systems as a training program for children who are critically ill. This article highlighted guidelines, limitations and challenges that need to be considered when designing exercise program using virtual reality gaming systems for critically ill children. This information is helpful given the popular use of virtual reality gaming systems in rehabilitation, particularly in children who are critically ill.

Muscle wasting during critical illness impairs recovery. Dietary strategies to minimise wasting include nutritional supplements, particularly essential amino acids. We reviewed the evidence on enteral supplementation with amino acids or their metabolites in the critically ill and in muscle wasting illness with similarities to critical illness, aiming to assess whether this intervention could limit muscle wasting in vulnerable patient groups. Citation databases, including MEDLINE, Web of Knowledge, EMBASE, the meta-register of controlled trials and the Cochrane Collaboration library, were searched for articles from 1950 to 2013. Search terms included 'critical illness', 'muscle wasting', 'amino acid supplementation', 'chronic obstructive pulmonary disease', 'chronic heart failure', 'sarcopenia' and 'disuse atrophy'. Reviews, observational studies, sport nutrition, intravenous supplementation and studies in children were excluded. One hundred and eighty studies were assessed for eligibility and 158 were excluded. Twenty-two studies were graded according to standardised criteria using the GRADE methodology: four in critical care populations, and 18 from other clinically relevant areas. Methodologies, interventions and outcome measures used were highly heterogeneous and meta-analysis was not appropriate. Methodology and quality of studies were too varied to draw any firm conclusion. Dietary manipulation with leucine enriched essential amino acids (EAA), β-hydroxy-β-methylbutyrate and creatine warrant further investigation in critical care; EAA has demonstrated improvements in body composition and nutritional status in other groups with muscle wasting illness. High-quality research is required in critical care before treatment recommendations can be made. © 2014 The British Dietetic Association Ltd.

Repeat sternotomy for left ventricular assist device insertion may result in injury to the right heart or patent coronary grafts, complicating intraoperative and postoperative management. In 4 critically ill patients, left thoracotomy was used as an alternative to repeat sternotomy. Anastomosis of the outflow conduit to the descending thoracic aorta provided satisfactory hemodynamic support.

Sepsis is a serious worldwide health care condition that is associated with high mortality rates, despite improvements in the ability to manage infection. New guidelines for the management of sepsis were recently released that advocate for implementation of care based on evidence-based practice for both adult and pediatric patients. Critical care nurses are directly involved in the assessment of patients at risk for developing sepsis and in the treatment of patients with sepsis and can, therefore, affect outcomes for critically ill patients. Nurses' knowledge of the recommendations in the new guidelines can help to ensure that patients with sepsis receive therapies that are based on the latest scientific evidence. This article presents an overview of new evidence-based recommendations for the treatment of adult patients with sepsis, highlighting the role of critical care nurses.

Fluid balance is a fundamental management of patients with sepsis, and this study aimed to investigate the impact of cumulative fluid balance on critically ill patients with influenza admitted to an intensive care unit (ICU). This multicenter retrospective cohort study was conducted by the Taiwan Severe Influenza Research Consortium (TSIRC) which includes eight medical centers. Patients with virology-proven influenza infection admitted to ICUs between October 2015 and March 2016 were included for analysis. A total of 296 patients were enrolled (mean age: 61.4±15.6 years; 62.8% men), and 92.2% (273/296) of them required mechanical ventilation. In the survivors, the daily fluid balance was positive from day 1 to day 3, and then gradually became negative from day 4 to day 7, whereas daily fluid balance was continuously positive in the non-survivors. Using the cumulative fluid balance from day 1-4 as a cut-off point, we found that a negative cumulative day 1-4 fluid balance was associated with a lower 30-day mortality rate (log-rank test, P = 0.003). To evaluate the impact of shock on this association, we divided the patients into shock and non-shock groups. The positive correlation between negative day 1-4 fluid balance and mortality was significant in the non-shock group (log-rank test, P = 0.008), but not in the shock group (log-rank test, P = 0.396). In a multivariate Cox proportional hazard regression model adjusted for age, sex, cerebrovascular disease, and PaO2/FiO2, day 1-4 fluid balance was independently associated with a higher 30-day mortality rate (aHR 1.088, 95% CI: 1.007-1.174). A negative day 1-4 cumulative fluid balance was associated with a lower mortality rate in critically ill patients with influenza. Our findings indicate the critical role of conservative fluid strategy in the management of patients with complicated influenza.

Nurses' prioritization of enteral nutrition in intensive care units: a national survey.

2018-05-01

Enteral nutrition is important in critically ill patients to improve patient outcomes, with nurses playing a pivotal role in the delivery and ongoing care of enteral nutrition. A significant deficit in nurses' knowledge and education relating to enteral nutrition has been identified, leading to iatrogenic malnutrition and potentially compromising patient care. Enteral nutrition appears to be prioritized lower than many other aspects of care. However, there is scant research to show how nurses prioritize enteral nutrition. This study aimed to explore how nurses prioritize enteral nutrition when caring for a critically ill patient. A descriptive online questionnaire, administered in May 2014, was utilized to explore the study aim. Descriptive statistics were performed to evaluate quantitative data. Content analysis was used to evaluate qualitative data. A total of 359 responses were included in data analysis (response rate 20.8%). All respondents were registered nurses working within an Australian intensive care unit or high dependency unit. Nurses agreed that enteral nutrition was very important and should be commenced as soon as possible. However, life-saving procedures always took priority and there were often multiple barriers that hindered optimal delivery of enteral nutrition. Respondents relied on their clinical judgement to inform decisions in relation to enteral nutrition in critically ill patients. Most respondents agreed that enteral nutrition was an important aspect of patient care, but acknowledged that other aspects of care were prioritized more highly. Despite this, some delays to enteral nutrition were perceived to be avoidable, and nurses recognized a need to advocate on the patient's behalf to increase the visibility of enteral nutrition. The findings of this study demonstrate that enteral nutrition is often prioritized lower than other competing care needs in the critically ill patient. Given the importance of enteral nutrition to patient recovery, changes to clinical practice to improve enteral nutrition management are necessary. © 2017 British Association of Critical Care Nurses.

Past disasters have highlighted the need to prepare for subsets of critically ill, medically fragile patients. These special patient populations require focused disaster planning that will address their medical needs throughout the event to prevent clinical deterioration. The suggestions in this article are important for all who are involved in large-scale disasters or pandemics with multiple critically ill or injured patients, including frontline clinicians, hospital administrators, and public health or government officials. Key questions regarding the care of critically ill or injured special populations during disasters or pandemics were identified, and a systematic literature review (1985-2013) was performed. No studies of sufficient quality were identified. Therefore, the panel developed expert opinion-based suggestions using a modified Delphi process. The panel did not include pediatrics as a separate special population because pediatrics issues are embedded in each consensus document. Fourteen suggestions were formulated regarding the care of critically ill and injured patients from special populations during pandemics and disasters. The suggestions cover the following areas: defining special populations for mass critical care, special population planning, planning for access to regionalized service for special populations, triage and resource allocation of special populations, therapeutic considerations, and crisis standards of care for special populations. Chronically ill, technologically dependent, and complex critically ill patients present a unique challenge to preparing and implementing mass critical care. There are, however, unique opportunities to engage patients, primary physicians, advocacy groups, and professional organizations to lessen the impact of disaster on these special populations.

To investigate the proximal gastric motor response to duodenal nutrients in critically ill patients with long-standing type 2 diabetes mellitus. Proximal gastric motility was assessed (using a barostat) in 10 critically ill patients with type 2 diabetes mellitus (59 +/- 3 years) during two 60-min duodenal infusions of Ensure (1 and 2 kcal/min), in random order, separated by 2 h fasting. Data were compared with 15 non-diabetic critically ill patients (48 +/- 5 years) and 10 healthy volunteers (28 +/- 3 years). Baseline proximal gastric volumes were similar between the three groups. In diabetic patients, proximal gastric relaxation during 1 kcal/min nutrient infusion was similar to non-diabetic patients and healthy controls. In contrast, relaxation during 2 kcal/min infusion was initially reduced in diabetic patients (P < 0.05) but increased to a level similar to healthy humans, unlike non-diabetic patients where relaxation was impaired throughout the infusion. Duodenal nutrient stimulation reduced the fundic wave frequency in a dose-dependent fashion in both the critically ill diabetic patients and healthy subjects, but not in critically ill patients without diabetes. Fundic wave frequency in diabetic patients and healthy subjects was greater than in non-diabetic patients. In patients with diabetes mellitus, proximal gastric motility is less disturbed than non-diabetic patients during critical illness, suggesting that these patients may not be at greater risk of delayed gastric emptying.

Purpose Optimal triage of patients at risk of critical illness requires accurate risk prediction, yet little data exists on the performance criteria required of a potential biomarker to be clinically useful. Materials and Methods We studied an adult cohort of non-arrest, non-trauma emergency medical services encounters transported to a hospital from 2002–2006. We simulated hypothetical biomarkers increasingly associated with critical illness during hospitalization, and determined the biomarker strength and sample size necessary to improve risk classification beyond a best clinical model. Results Of 57,647 encounters, 3,121 (5.4%) were hospitalized with critical illness and 54,526 (94.6%) without critical illness. The addition of a moderate strength biomarker (odds ratio=3.0 for critical illness) to a clinical model improved discrimination (c-statistic 0.85 vs. 0.8, p<0.01), reclassification (net reclassification improvement=0.15, 95%CI: 0.13,0.18), and increased the proportion of cases in the highest risk categoryby+8.6% (95%CI: 7.5,10.8%). Introducing correlation between the biomarker and physiological variables in the clinical risk score did not modify the results. Statistically significant changes in net reclassification required a sample size of at least 1000 subjects. Conclusions Clinical models for triage of critical illness could be significantly improved by incorporating biomarkers, yet, substantial sample sizes and biomarker strength may be required.

Abstract Bilateral diaphragmatic paralysis (BDP) manifests as respiratory muscle weakness, and its association with critical illness polyneuropathy (CIP) was rarely reported. Here, we present a patient with BDP related to CIP, who successfully avoided tracheostomy after diagnosis and management. A 71-year-old male presented with acute respiratory failure after sepsis adequately treated. Repeated intubation occurred because of carbon dioxide retention after each extubation. After eliminating possible factors, septic shock-induced respiratory muscle weakness was suspected. Physical examination, a nerve conduction study, and chest ultrasound confirmed our impression. Pulmonary rehabilitation and reconditioning exercises were arranged, and the patient was discharged with a diagnosis of BDP. The diagnosis of BDP is usually delayed, and there are only sporadic reports on its association with polyneuropathy, especially in patients with preserved limb muscle function. Therefore, when physicians encounter patients that are difficult to wean from mechanical ventilation, CIP associated with BDP should be considered in the differential diagnosis. PMID:26252301

Hemodynamic monitoring in the critically ill.

Monitoring of vital functions is one of the most important and essential tools in the management of critically ill patients in the ICU. Today it is possible to detect and analyze a great variety of physiological signals by various noninvasive and invasive techniques. An intensivist should be able to select and perform the most appropriate monitoring method for the individual patient considering risk-benefit ratio of the particular monitoring technique and the need for immediate therapy, specific diagnosis, continuous monitoring and evaluation of morphology should be included. Despite rapid development of noninvasive monitoring techniques, invasive hemodynamic monitoring in still one of the most basic ICU procedures. It enables monitoring of pressures, flow and saturation, pressures in the systemic and pulmonary circulation, estimation of cardiac performance and judgment of the adequacy of the cardiocirculatory system. Carefully and correctly obtained information are basis for proper hemodynamic assessment which usually effects the therapeutic decisions.

Sleep Disturbance after Hospitalization and Critical Illness: A Systematic Review.

Sleep disturbance during intensive care unit (ICU) admission is common and severe. Sleep disturbance has been observed in survivors of critical illness even after transfer out of the ICU. Not only is sleep important to overall health and well being, but patients after critical illness are also in a physiologically vulnerable state. Understanding how sleep disturbance impacts recovery from critical illness after hospital discharge is therefore clinically meaningful. This Systematic Review aimed to summarize studies that identify the prevalence of and risk factors for sleep disturbance after hospital discharge for critical illness survivors. PubMed (January 4, 2017), MEDLINE (January 4, 2017), and EMBASE (February 1, 2017). Databases were searched for studies of critically ill adult patients after hospital discharge, with sleep disturbance measured as a primary outcome by standardized questionnaire or objective measurement tools. From each relevant study, we extracted prevalence and severity of sleep disturbance at each time point, objective sleep parameters (such as total sleep time, sleep efficiency, and arousal index), and risk factors for sleep disturbance. A total of 22 studies were identified, with assessment tools including subjective questionnaires, polysomnography, and actigraphy. Subjective questionnaire studies reveal a 50-66.7% (within 1 mo), 34-64.3% (>1-3 mo), 22-57% (>3-6 mo), and 10-61% (>6 mo) prevalence of abnormal sleep after hospital discharge after critical illness. Of the studies assessing multiple time points, four of five questionnaire studies and five of five polysomnography studies show improved aspects of sleep over time. Risk factors for poor sleep varied, but prehospital factors (chronic comorbidity, pre-existing sleep abnormality) and in-hospital factors (severity of acute illness, in-hospital sleep disturbance, pain medication use, and ICU acute stress symptoms) may play a role. Sleep disturbance was frequently associated with postdischarge psychological comorbidities and impaired quality of life. Sleep disturbance is common in critically ill patients up to 12 months after hospital discharge. Both subjective and objective studies, however, suggest that sleep disturbance improves over time. More research is needed to understand and optimize sleep in recovery from critical illness.

Summary Background Genetic disorders and congenital anomalies are the leading causes of infant mortality. Diagnosis of most genetic diseases in neonatal and paediatric intensive care units (NICU and PICU) is not sufficiently timely to guide acute clinical management. We used rapid whole-genome sequencing (STATseq) in a level 4 NICU and PICU to assess the rate and types of molecular diagnoses, and the prevalence, types, and effect of diagnoses that are likely to change medical management in critically ill infants. Methods We did a retrospective comparison of STATseq and standard genetic testing in a case series from the NICU and PICU of a large children's hospital between Nov 11, 2011, and Oct 1, 2014. The participants were families with an infant younger than 4 months with an acute illness of suspected genetic cause. The intervention was STATseq of trios (both parents and their affected infant). The main measures were the diagnostic rate, time to diagnosis, and rate of change in management after standard genetic testing and STATseq. Findings 20 (57%) of 35 infants were diagnosed with a genetic disease by use of STATseq and three (9%) of 32 by use of standard genetic testing (p=0·0002). Median time to genome analysis was 5 days (range 3–153) and median time to STATseq report was 23 days (5–912). 13 (65%) of 20 STATseq diagnoses were associated with de-novo mutations. Acute clinical usefulness was noted in 13 (65%) of 20 infants with a STATseq diagnosis, four (20%) had diagnoses with strongly favourable effects on management, and six (30%) were started on palliative care. 120-day mortality was 57% (12 of 21) in infants with a genetic diagnosis. Interpretation In selected acutely ill infants, STATseq had a high rate of diagnosis of genetic disorders. Most diagnoses altered the management of infants in the NICU or PICU. The very high infant mortality rate indicates a substantial need for rapid genomic diagnoses to be allied with a novel framework for precision medicine for infants in NICU and PICU who are diagnosed with genetic diseases to improve outcomes.

Objective To validate serum neutrophil gelatinase-associated lipocalin (NGAL) as an early biomarker for acute kidney injury (AKI) in critically ill children with septic shock. Design Observational cohort study. Setting 15 North American pediatric intensive care units (PICU). Patients A total of 143 critically ill children with SIRS or septic shock and 25 healthy controls. Interventions None. Measurements and Main Results Serum NGAL was measured during the first 24 hours of admission to the PICU. AKI was defined as a blood urea nitrogen (BUN) concentration > 100 mg/dL, serum creatinine > 2 mg/dL in the absence of pre-existing renal disease, or the need for dialysis. There was a significant difference in serum NGAL between healthy children (median 80 ng/mL, IQR 55.5-85.5 ng/mL), critically ill children with SIRS (median 107.5 ng/mL, IQR 89-178.5 ng/mL), and critically ill children with septic shock (median 302 ng/mL, IQR 151-570 ng/mL; p<0.001). AKI developed in 22 out of 143 (15.4%) critically ill children. Serum NGAL was significantly increased in critically ill children with AKI (median 355 ng/mL, IQR 166-1322 ng/mL) compared to those without AKI (median 186 ng/mL, IQR 98-365 ng/mL; p=0.009). Conclusions Serum NGAL is a highly sensitive, but nonspecific predictor of AKI in critically ill children with septic shock. Further validation of serum NGAL as a biomarker of AKI in this population is warranted. PMID:18379258

Transfusion-related immunomodulation (TRIM) in the intensive care unit (ICU) is difficult to define and likely represents a complicated set of physiologic responses to transfusion, including both proinflammatory and immunosuppressive effects. Similarly, the immunologic response to critical illness in both adults and children is highly complex and is characterized by both acute inflammation and acquired immune suppression. How transfusion may contribute to or perpetuate these phenotypes in the ICU is poorly understood, despite the fact that transfusion is common in critically ill patients. Both hyperinflammation and severe immune suppression are associated with poor outcomes from critical illness, underscoring the need to understand potential immunologic consequences of blood product transfusion. In this review we outline the dynamic immunologic response to critical illness, provide clinical evidence in support of immunomodulatory effects of blood product transfusion, review preclinical and translational studies to date of TRIM, and provide insight into future research directions. © 2016 AABB.

2014-01-01

Levosimendan, the active enantiomer of simendan, is a calcium sensitizer developed for treatment of decompensated heart failure, exerts its effects independently of the beta adrenergic receptor and seems beneficial in cases of severe, intractable heart failure. Levosimendan is usually administered as 24-h infusion, with or without a loading dose, but dosing needs adjustment in patients with severe liver or renal dysfunction. Despite several promising reports, the role of levosimendan in critical illness has not been thoroughly evaluated. Available evidence suggests that levosimendan is a safe treatment option in critically ill patients and may reduce mortality from cardiac failure. However, data from well-designed randomized controlled trials in critically ill patients are needed to validate or refute these preliminary conclusions. This literature review is an attempt to synthesize available evidence on the role and possible benefits of levosimendan in critically ill patients with severe heart failure. PMID:24578748

Non-cardiac critically ill patients with type II myocardial infarction (MI) have a high risk of mortality. There are no evidence-based interventions to mitigate this risk. We systematically reviewed the literature regarding the use of medications known to reduce mortality in patients with cardiac troponin (cTn) elevation due to type I MI (β blockers, statin, and aspirin) in studies of critically ill patients without Type I MI. All PubMed publications between 1976-2/19/16 were reviewed. Search terms included: β blocker or aspirin or statin and intensive care unit (ICU) or critically ill or sepsis; 497 primary references were obtained. Inclusion criteria were as follows: (1) study population consisted of critically ill patients in the ICU with non-cardiovascular illnesses, (2) mortality end point, (3) severity of illness (or injury) was measured, and (4) the antiplatelet agent was primarily aspirin. Retrospective investigations, prospective observational studies, meta-analysis, systematic review, and randomized controlled trials were included; case reports were excluded. 25 primary references were obtained. The data were extracted and tabulated using data collection headings as follows: article title, first author/year/reference number, study type/design, population studied, outcome and intervention, and study question addressed. Evidence was not graded as the majority of studies were non-randomized (low-to-moderate quality). 11 studies were found through bibliography reviews for a total of 36 references. In conclusion, β blockers, statins, and aspirin may play a role in reducing mortality in non-cardiac critically ill patients. Benefit appears to be related to severity of illness, for which cTn may be a marker. Copyright © 2017 American Federation for Medical Research.

End-of-life decision making in the ICU.

PubMed

Siegel, Mark D

2009-03-01

A large proportion of deaths, particularly in the developed world, follows admission to an ICU. Therefore, end-of life decision making is an essential facet of critical care practice. For intensivists, managing death in the critically ill has become a key professional skill. They must be thoroughly familiar with the ethical framework that guides end-of-life decision making. Decisions should generally be made collaboratively by clinicians partnering with patients' families. Treatment choices should be crafted to meet specific, achievable goals. A rational, empathic approach to working with families should encourage appropriate, mutually satisfactory outcomes.

Construction industry is an important sector that contributes to the development of economy and socioeconomy in Malaysia. It is a vital component in achieving the developed country status. However, fatalities in the Malaysian construction industry are a critical problem. Number of fatalities in this industry is the highest compared to other industries registered in Malaysia under the investigation of Department of Occupational Safety and Health (DOSH). Worksite element (worksite conditions, poor site management, construction tasks, and equipment & materials) was identified as one category of causes of occupational accidents and illnesses in Malaysian construction industry. The main objective of this study is to understand the perception of local construction personnel in terms of worksite element as causes of occupational accidents and illnesses in Malaysian residential construction industry. 13 housing projects that were registered with Ministry of Urban Wellbeing, Housing and Local Government and being permitted to perform construction work in 2012 were selected in Pulau Pinang to be studied using questionnaire survey. Worksite condition and poor site management was perceived as the most significant with the mean values of 3.68 and 3.61 respectively.

Patients admitted to the ICU after severe trauma require frequent procedures in the operating room, particularly in cases where a damage control strategy is used. The ventilatory management of these patients in the operating room can be particularly challenging. These patients often have severely impaired respiratory mechanics because of acute lung injury and abdominal compartment syndrome. Consequently, the pressure and flow generation capabilities of standard anesthesia ventilators may be inadequate to support ventilation and gas exchange. This article presents the problems that may be encountered in patients who have severe abdominal and lung injuries, and the current management concepts used in caring for these patients in the critical care setting, to provide guidelines for the anesthetist faced with these patients in the operating room.

Redefining the gut as the motor of critical illness

PubMed Central

Mittal, Rohit; Coopersmith, Craig M.

2013-01-01

The gut is hypothesized to play a central role in the progression of sepsis and multiple organ dysfunction syndrome. Critical illness alters gut integrity by increasing epithelial apoptosis and permeability and by decreasing epithelial proliferation and mucus integrity. Additionally, toxic gut-derived lymph induces distant organ injury. Although the endogenous microflora ordinarily exist in a symbiotic relationship with the gut epithelium, severe physiologic insults alter this relationship, leading to induction of virulence factors in the microbiome, which, in turn, can perpetuate or worsen critical illness. This review highlights newly discovered ways in which the gut acts as the motor that perpetuates the systemic inflammatory response in critical illness. PMID:24055446

The diagnostic value of troponin in critically ill.

PubMed

Voga, Gorazd

2010-01-01

Troponin T and I are sensitive and specific markers of myocardial necrosis. They are used for the routine diagnosis of acute coronary syndrome. In critically ill patients they are basic diagnostic tool for diagnosis of myocardial necrosis due to myocardial ischemia. Moreover, the increase of troponin I and T is related with adverse outcome in many subgroups of critically ill patients. The new, high sensitivity tests which have been developed recently allow earlier and more accurate diagnosis of acute coronary syndrome. The use of the new tests has not been studied in critically ill patients, but they will probably replace the old tests and will be used on the routine basis.

New insights into the gut as the driver of critical illness and organ failure.

The gut has long been hypothesized to be the 'motor' of multiple organ dysfunction syndrome. This review serves as an update on new data elucidating the role of the gut as the propagator of organ failure in critical illness. Under basal conditions, the gut absorbs nutrients and serves as a barrier that prevents approximately 40 trillion intraluminal microbes and their products from causing host injury. However, in critical illness, gut integrity is disrupted with hyperpermeability and increased epithelial apoptosis, allowing contamination of extraluminal sites that are ordinarily sterile. These alterations in gut integrity are further exacerbated in the setting of preexisting comorbidities. The normally commensal microflora is also altered in critical illness, with increases in microbial virulence and decreases in diversity, which leads to further pathologic responses within the host. All components of the gut are adversely impacted by critical illness. Gut injury can not only propagate local damage, but can also cause distant injury and organ failure. Understanding how the multifaceted components of the gut interact and how these are perturbed in critical illness may play an important role in turning off the 'motor' of multiple organ dysfunction syndrome in the future.

Glutamine and antioxidants: status of their use in critical illness.

PubMed

van Zanten, Arthur R H

2015-03-01

Many studies in critically ill patients have addressed enteral or parenteral supplementation of glutamine and antioxidants to counteract assumed deficiencies and induce immune-modulating effects to reduce infections and improve outcome. Older studies showed marked reductions in mortality, infectious morbidity and length of stay. Recent studies no longer show beneficial effects and in contrast even demonstrated increased mortality. This opiniating review focuses on the latest information and the consequences for the use of glutamine and antioxidants in critically ill patients. Positive effects in systematic reviews and meta-analyses are based on results from older, smaller and mainly single-centre studies. New information has challenged the conditional deficiency hypothesis concerning glutamine in critically ill patients. The recent REDOXS and MetaPlus trials studying the effects of glutamine, selenium and other antioxidants have shown no benefits and increased mortality. Given that the first dictum in medicine is to do no harm, we cannot be confident that immune-modulating nutrient supplementation with glutamine and antioxidants is effective and well tolerated for critically ill patients. Until more data are available, it is probably better not to routinely administer glutamine and antioxidants in nonphysiological doses to mechanically ventilated critically ill patients.

How do we approach thrombocytopenia in critically ill patients?

PubMed

Thachil, Jecko; Warkentin, Theodore E

2017-04-01

A low platelet count is a frequently encountered haematological abnormality in patients treated in intensive treatment units (ITUs). Although severe thrombocytopenia (platelet count <20 × 10 9 /l) can be associated with bleeding, even moderate-degree thrombocytopenia is associated with organ failure and adverse prognosis. The aetiology for thrombocytopenia in ITU is often multifactorial and correcting one aetiology may not normalise the low platelet count. The classical view for thrombocytopenia in this setting is consumption associated with thrombin-mediated platelet activation, but other concepts, including platelet adhesion to endothelial cells and leucocytes, platelet aggregation by increased von Willebrand factor release, red cell damage and histone release, and platelet destruction by the complement system, have recently been described. The management of severe thrombocytopenia is platelet transfusion in the presence of active bleeding or invasive procedure, but the risk-benefit of prophylactic platelet transfusions in this setting is uncertain. In this review, the incidence and mechanisms of thrombocytopenia in patients with ITU, its prognostic significance and the impact on organ function is discussed. A practical approach based on the authors' experience is described to guide management of a critically ill patient who develops thrombocytopenia. © 2016 John Wiley & Sons Ltd.

Discuss the research needs of the critical illness and injury communities in the United States. Workshop session held during the 5 National Institutes of Health Symposium on the Functional Genomics of Critical Illness and Injury (November 15, 2007). The current clinical research infrastructure misses opportunities for synergy and does not address many important needs. In addition, it remains challenging to rapidly and properly implement system-wide changes based upon reproducible evidence from clinical research. Author presentations, panel discussion, attendee feedback. The critical illness and injury research communities seek better communication and interaction, both of which will improve the breadth and quality of acute care research. Success in meeting these needs should come from cooperative and strategic actions that favor collaboration, standardization of protocols, and strong leadership. An alliance framed on common goals will foster collaboration among experts to better promote clinical trials within the critically ill or injured patient population. The U.S. Critical Illness and Injury Trials Group was funded to create a clinical research framework that can reduce the barriers to investigation using an investigator-initiated, evidence-driven, inclusive approach that has proven successful elsewhere. This alliance will provide an annual venue for systematic review and strategic planning that will include framing the research agenda, raising awareness for the value of acute care research, gathering and promoting best practices, and bolstering the critical care workforce.

Point-of-Care Ultrasound: A Trend in Health Care.

Buerger, Anita M; Clark, Kevin R

2017-11-01

To discuss the current and growing use of point-of-care (POC) ultrasound in the management and care of patients. Several electronic research databases were searched to find articles that emphasized the use of POC ultrasound by health care providers who manage and treat critically ill or injured patients. Thirty-five relevant peer-reviewed journal articles were selected for this literature review. Common themes identified in the literature included the use of POC ultrasound in emergency medicine, military medicine, and remote care; comparison of POC ultrasound to other medical imaging modalities; investigation of the education and training required for nonimaging health care professionals who perform POC ultrasound in their practices; and discussion of the financial implications and limitations of POC ultrasound. POC ultrasound provides clinicians with real-time information to better manage and treat critically ill or injured patients in emergency medicine, military medicine, and remote care. In addition to providing immediate bedside diagnostic information, use of POC ultrasound has increased because of concerns regarding radiation protection. Finally, the expansion of POC ultrasound to other specialty areas requires nonimaging health care professionals to perform bedside ultrasound examinations and interpret the resulting images. Because POC ultrasound is user-dependent, adequate training is essential for all who perform and interpret the examinations. Research involving POC ultrasound will continue as innovations and confidence in ultrasound applications advance. Future research should continue to examine the broad use of POC ultrasound in patient care and management. ©2017 American Society of Radiologic Technologists.

Part 1: Pressure ulcer assessment - the development of Critical Care Pressure Ulcer Assessment Tool made Easy (CALCULATE).

Critically ill patients are at high risk of developing pressure ulcers resulting in serious untoward patient and health care system outcomes. Pressure ulcer prevention is therefore an important patient safety priority and establishing a structured approach to pressure ulcer risk assessment to identify patients at risk is a critical first step. The literature was searched using three electronic databases from 2000 to 2011 to identify papers reporting on pressure ulcer risk factors and assessment in adult critical care. The review and appraisal of papers were conducted by two critical care nurses. Papers underwent detailed review if they met inclusion criteria where they identified pressure ulcer assessment scores, scales or risk factors and related to adult critical care patients Seven papers were reviewed. No single assessment tool was sufficiently validated for critically ill patients and seven key critical care risk factors were identified. These risk factors were: mechanical ventilation, impaired circulation, dialysis, long surgery, low protein and too unstable to turn. The tool Critical Care Pressure Ulcer Assessment Tool made Easy (CALCULATE) was developed utilizing the risk factors from the literature and expert critical care nursing consensus decision-making. In the absence of current consensus, valid assessment scales and limited evidence for the most appropriate pressure ulcer assessment for critically ill patients, this assessment tool offers an easy, appropriate alternative for critically ill patients than existing tools primarily validated for acute care wards. 'CALCULATE' offers an important contribution towards the advancement and development of critical care pressure ulcer risk assessment. Future research is needed to further enhance and inform pressure ulcer risk assessment of the critically ill patients. The identification of critical care risk factors may be an indicative method of assessing pressure ulcer risk in the critically ill patients. © 2015 British Association of Critical Care Nurses.

OBJECTIVE After prolonged opioid exposure, children develop opioid-induced hyperalgesia, tolerance, and withdrawal. Strategies for prevention and management should be based on the mechanisms of opioid tolerance and withdrawal. PATIENTS AND METHODS Relevant manuscripts published in the English language were searched in Medline by using search terms “opioid,” “opiate,” “sedation,” “analgesia,” “child,” “infant-newborn,” “tolerance,” “dependency,” “withdrawal,” “analgesic,” “receptor,” and “individual opioid drugs.” Clinical and preclinical studies were reviewed for data synthesis. RESULTS Mechanisms of opioid-induced hyperalgesia and tolerance suggest important drug- and patient-related risk factors that lead to tolerance and withdrawal. Opioid tolerance occurs earlier in the younger age groups, develops commonly during critical illness, and results more frequently from prolonged intravenous infusions of short-acting opioids. Treatment options include slowly tapering opioid doses, switching to longer-acting opioids, or specifically treating the symptoms of opioid withdrawal. Novel therapies may also include blocking the mechanisms of opioid tolerance, which would enhance the safety and effectiveness of opioid analgesia. CONCLUSIONS Opioid tolerance and withdrawal occur frequently in critically ill children. Novel insights into opioid receptor physiology and cellular biochemical changes will inform scientific approaches for the use of opioid analgesia and the prevention of opioid tolerance and withdrawal.

The experiences of patients' families in intensive care units (ICUs) are of international concern. In Greece however, adequate attention has not been paid to this issue. To explore the experiences of critical care patients' families in Greece. The intensive care units of 3 general district hospitals in the area of Athens, Greece. The social constructionist version of grounded theory was used. In-depth interviews with 25 relatives of critically ill patients were carried out, and participant and non-participant observation was used to cross-validate the data obtained. Seven major categories were identified, with 32 components across all categories. The experiences of families revolved around the two core categories of "Intense Emotions" and "Vigilant Attendance". The study conceptualised two new categories in this field, "Religiosity" and "Loss of Intimacy" and enhanced the category "Vigilant Attendance". Three further categories were identified, namely "Caring", "Dignity" and "Information". The various interrelationships between the categories were also examined. The study has examined the experience of Greek patients' families from a qualitative perspective and suggests that major changes need to be made in terms of management and support.

2014-05-01

Up to 700 million people are infected and more than a million die each year from mosquito-borne illness. While the vast majority of cases occur in endemic tropical and subtropical regions, international travel and migration patterns have increased their prevalence in North America. This review discusses the diagnosis and treatment of the 3 most common mosquito-borne illnesses seen in the United States: Plasmodium falciparum malaria, dengue, and West Nile virus. With no pathognomonic findings, it is critical that emergency clinicians in nonendemic areas maintain a high index of suspicion, conduct a thorough history/travel history, and interpret indirect findings to initiate prompt and appropriate treatment. This review gathers the best evidence from international public health resources, surveillance studies, guidelines, and academic research to give emergency clinicians tools to combat these potentially lethal infections.

Protocol for a longitudinal qualitative study: survivors of childhood critical illness exploring long-term psychosocial well-being and needs—The SCETCH Project

2014-01-01

Introduction Life-threatening critical illness affects over a quarter of a million children and adolescents (0–18 years old) annually in the USA and the UK. Death from critical illness is rare; however, survivors and their families can be exposed to a complex array of negative physical, psychological and social problems. Currently, within the literature, there is a distinct paucity of child and adolescent survivor self-reports, thus limiting our understanding of how survivors perceive this adversity and subsequently cope and grow in the long-term following their critical illness. This study aims to explore and understand psychosocial well-being and needs of critical illness survivors, 6–20 months post paediatric intensive care admission. Methods and analysis A longitudinal, qualitative approach will provide a platform for a holistic and contextualised exploration of outcomes and mechanisms at an individual level. Up to 80 participants, including 20 childhood critical illness survivors and 60 associated family members or health professionals/teachers, will be recruited. Three interviews, 7–9 weeks apart, will be conducted with critical illness survivors, allowing for the exploration of psychosocial well-being over time. A single interview will be conducted with the other participants enabling the exploration of contextual information and how psychosocial well-being may inter-relate between critical illness survivors and themselves. A ‘tool box’ of qualitative methods (semi-structured interviews, draw and tell, photo-elicitation, graphic-elicitation) will be used to collect data. Narrative analysis and pattern matching will be used to identify emergent themes across participants. Ethics and dissemination This study will provide an insight and understanding of participants’ experiences and perspectives of surviving critical illness in the long term with specific relation to their psychosocial well-being. Multiple methods will be used to ensure that the findings are effectively disseminated to service users, clinicians, policy and academic audiences. The study has full ethical approval from the East Midlands Research Ethics Committee and has received National Health Service (NHS) governance clearance. PMID:24435896

Addressing hyperglycemia from hospital admission to discharge.

Moghissi, Etie S

2010-03-01

This review examines glycemia management practices in hospitalized patients. Optimal glycemic control remains a challenge among hospitalized patients. Recent studies have questioned the benefit of tight glycemic control and have raised concerns regarding the safety of this approach. As a result, medical societies have updated glycemic targets and have published new consensus guidelines for management of glycemia in hospitalized patients. This review highlights recent inpatient glycemic trials, the new glycemic targets and recommended strategies for management of glycemia in hospitalized patients. Medline and PubMed searches (diabetes, hyperglycemia, hypoglycemia, intensive therapy insulin, tight glycemic control, and hospital patients) were performed for English-language articles on treatment of diabetes, insulin therapy, hyperglycemia or hypoglycemia in hospitalized patients published from 2004 to present. Earlier works cited in these papers were surveyed. Clinical studies, reviews, consensus/guidelines statements, and meta-analyses relevant to the identification and management of diabetes and hyperglycemia in hospitalized patients were included and selected. This is not an exhaustive review of the published literature. Insulin remains the most appropriate agent for a majority of hospitalized patients. In critically ill patients insulin is given as a continuous intravenous (IV) infusion and in non-critically ill inpatients hyperglycemia is best managed using scheduled subcutaneous (SC) basal-bolus insulin regimens supplemented with correction doses as needed and adjusted daily with the guidance of frequent blood glucose monitoring. Prevention of hypoglycemia is equally as important to patient outcomes and is an equally necessary part of any effective glucose control program. Modern insulin analogs offer advantages over the older human insulins (e.g., regular and neutral protamine Hagedorn [NPH] insulin) because their time-action profiles more closely correspond to physiological basal and prandial insulin requirements, and have a lower propensity for inducing hypoglycemia than human insulin formulations. Long-acting basal insulin analogs (glargine, detemir) are suitable and preferred for the basal component of therapy; rapid-acting insulin analogs (aspart, lispro, glulisine) are recommended for bolus and correction doses. Sliding-scale insulin (SSI) regimens are not effective and should not be used, especially as this excludes a basal insulin component from the therapy. Optimal glycemic management in the hospital setting requires judicious treatment of hyperglycemia while avoiding hypoglycemia. Insulin is the most appropriate agent for management of hyperglycemia for the majority of hospitalized patients. Intravenous insulin infusion is still preferred during and immediately after surgery, but s.c. basal insulin analogs with prandial or correction doses should be used after the immediate post-operative period, and also should be used in non-critically ill patients. Frequent and effective glucose monitoring is critical for avoiding wide deviations from acceptable glucose levels, which under a recently promulgated consensus guideline currently range between 140 mg/dL and 180 mg/dL. Glucose targets near 140 mg/dL are recommended as being the most appropriate for all hospitalized patients.

Over the coming years, accelerating progress against cancer will be associated with an increased number of patients who require life-sustaining therapies for infectious or toxic chemotherapy-related events. Major changes include increased number of cancer patients admitted to the ICU with full-code status or for time-limited trials, increased survival and quality of life in ICU survivors, changing prognostic factors, early ICU admission for optimal monitoring, and use of noninvasive diagnostic and therapeutic strategies. In this review, experts in the management of critically ill cancer patients highlight recent changes in the use and the results of intensive care in patients with malignancies. They seek to put forward a standard of care for the management of these patients and highlight important updates that are required to care for them. The research agenda they suggest includes important studies to be conducted in the next few years to increase our understanding of organ dysfunction in this population and to improve our ability to appropriately use life-saving therapies or select new therapeutic approaches that are likely to improve outcomes. This review aims to provide more guidance for the daily management of patients with cancer, in whom outcomes are constantly improving, as is our global ability to fight against what is becoming the leading cause of mortality in industrialized and non-industrialized countries.

At 07:39 on 11 March 2004, 10 terrorist bomb explosions occurred almost simultaneously in four commuter trains in Madrid, Spain, killing 177 people instantly and injuring more than 2000. There were 14 subsequent in-hospital deaths, bringing the ultimate death toll to 191. This report describes the organization of clinical management and patterns of injuries in casualties who were taken to the closest hospital, with an emphasis on the critically ill. A total of 312 patients were taken to the hospital and 91 patients were hospitalized, of whom 89 (28.5%) remained in hospital for longer than 24 hours. Sixty-two patients had only superficial bruises or emotional shock, but the remaining 250 patients had more severe injuries. Data on 243 of these 250 patients form the basis of this report. Tympanic perforation occurred in 41% of 243 victims with moderate-to-severe trauma, chest injuries in 40%, shrapnel wounds in 36%, fractures in 18%, first-degree or second-degree burns in 18%, eye lesions in 18%, head trauma in 12% and abdominal injuries in 5%. Between 08:00 and 17:00, 34 surgical interventions were performed in 32 patients. Twenty-nine casualties (12% of the total, or 32.5% of those hospitalized) were deemed to be in a critical condition, and two of these died within minutes of arrival. The other 27 survived to admission to intensive care units, and three of them died, bringing the critical mortality rate to 17.2% (5/29). The mean Injury Severity Score and Acute Physiology and Chronic Health Evaluation II scores for critically ill patients were 34 and 23, respectively. Among these critically ill patients, soft tissue and musculoskeletal injuries predominated in 85% of cases, ear blast injury was identified in 67% and blast lung injury was present in 63%. Fifty-two per cent suffered head trauma. Over-triage to the closest hospital probably occurred, and the time of the blasts proved to be crucial to the the adequacy of the medical and surgical response. The number of blast lung injuries seen is probably the largest reported by a single institution, and the critical mortality rate was reasonably low. PMID:15693992

This article provides consensus suggestions for expanding critical care surge capacity and extension of critical care service capabilities in disasters or pandemics. It focuses on the principles and frameworks for expansion of intensive care services in hospitals in the developed world. A companion article addresses surge logistics, those elements that provide the capability to deliver mass critical care in disaster events. The suggestions in this article are important for all who are involved in large-scale disasters or pandemics with injured or critically ill multiple patients, including front-line clinicians, hospital administrators, and public health or government officials. The Surge Capacity topic panel developed 23 key questions focused on the following domains: systems issues; equipment, supplies, and pharmaceuticals; staffing; and informatics. Literature searches were conducted to identify evidence on which to base key suggestions. Most reports were small scale, were observational, or used flawed modeling; hence, the level of evidence on which to base recommendations was poor and did not permit the development of evidence-based recommendations. Therefore, the panel developed expert opinion-based suggestions using a modified Delphi process. Suggestions from the previous task force were also included for validation by the expert panel. This article presents 10 suggestions pertaining to the principles that should guide surge capacity and capability planning for mass critical care, including the role of critical care in disaster planning; the surge continuum; targets of surge response; situational awareness and information sharing; mitigating the impact on critical care; planning for the care of special populations; and service deescalation/cessation (also considered as engineered failure). Future reports on critical care surge should emphasize population-based outcomes as well as logistical details. Planning should be based on the projected number of critically ill or injured patients resulting from specific scenarios. This should include a consideration of ICU patient care requirements over time and must factor in resource constraints that may limit the ability to provide care. Standard ICU management forms and patient data forms to assess ICU surge capacity impacts should be created and used in disaster events.

Toward an Integrated Research Agenda for Critical Illness in Aging

Aging brings an increased predisposition to critical illness. Patients older than 65 years of age account for approximately half of all intensive care unit (ICU) admissions in the United States, a proportion that is expected to increase considerably with the aging of the population. Emerging research suggests that elderly survivors of intensive care suffer significant long-term sequelae, including accelerated age-related functional decline. Existing evidence-based interventions are frequently underused and their efficacy untested in older subjects. Improving ICU outcomes in the elderly will require not only better methods for translating sound science into improved ICU practice but also an enhanced understanding of the underlying molecular, physiological, and pathophysiological interactions of critical illness with the aging process itself. Yet, significant barriers to research for critical illness in aging exist. We review the state of knowledge and identify gaps in knowledge, research opportunities, and barriers to research, with the goal of promoting an integrated research agenda for critical illness in aging.

Sleep is an important physiologic process, and lack of sleep is associated with a host of adverse outcomes. Basic and clinical research has documented the important role circadian rhythm plays in biologic function. Critical illness is a time of extreme vulnerability for patients, and the important role sleep may play in recovery for intensive care unit (ICU) patients is just beginning to be explored. This concise clinical review focuses on the current state of research examining sleep in critical illness. We discuss sleep and circadian rhythm abnormalities that occur in ICU patients and the challenges to measuring alterations in circadian rhythm in critical illness and review methods to measure sleep in the ICU, including polysomnography, actigraphy, and questionnaires. We discuss data on the impact of potentially modifiable disruptors to patient sleep, such as noise, light, and patient care activities, and report on potential methods to improve sleep in the setting of critical illness. Finally, we review the latest literature on sleep disturbances that persist or develop after critical illness. PMID:25594808

Energy metabolism of critically ill children has its own characteristics, especially for those undergoing mechanical ventilation. We tried to assess the energy expenditure status and evaluate the use of predictive equations in such children. Moreover, the characteristics of the energy metabolism among various situation were explored. Fifty critically ill children undergoing mechanical ventilation were selected in this study. Data produced during the 24 hours of mechanical ventilation were collected for computation of severity of illness. Resting energy expenditure (REE) was determined at 24 hours after mechanical ventilation (MREE). Predictive resting energy expenditure (PREE) was calculated for each subject using age-appropriate equations (Schofield-HTWT, White). The study was approved by the hospital medical ethics committee and obtained parental written informed consent. The pediatric risk of mortality score 3 (PRISM3) and pediatric critical illness score (PCIS) were (7 ± 3) and (82 ± 4), respectively. MREE, Schofield-HTWT equation PREE and White equation PREE were (404.80 ± 178.28), (462.82 ± 160.38) and (427.97 ± 152.30) kcal/d, respectively; 70% were hypometabolic and 10% were hypermetabolic. MREE and PREE which were calculated using Schofield-HTWT equation and White equation, both were higher than MREE (P = 0.029). Correlation analysis was performed between PRISM3 and PCIS with MREE. There were no statistically significant correlation (P > 0.05). The hypometabolic response is apparent in critically ill children with mechanical ventilation; Schofield-HTWT equation and White equation could not predict energy requirements within acceptable clinical accuracy. In critically ill children undergoing mechanical ventilation, the energy expenditure is not correlated with the severity of illness.

The Theory of Dyadic Illness Management.

PubMed

Lyons, Karen S; Lee, Christopher S

2018-02-01

Despite the importance of both members of the adult patient-care partner dyad, a majority of research on illness management is focused on the patient or the care partner. The basic principle of the Theory of Dyadic Illness Management is that illness management is a dyadic phenomenon; the theory focuses extensively on the dyad as an interdependent team. The way dyads appraise illness as a unit influences the ways in which they engage in behaviors to manage illness together in a recursive fashion that influences dyadic health. Optimizing the health of both members of the dyad is a goal of the theory. In turn, the health of the dyad can feedback to influence how they appraise and manage illness together. Finally, dyadic illness management is an inherently variable process that is influenced by several contextual factors. Supportive evidence and implications for practice and future research are presented.

New insights into the gut as the driver of critical illness and organ failure

Meng, Mei; Klingensmith, Nathan J.; Coopersmith, Craig M.

2017-01-01

Purpose of review The gut has long been hypothesized to be the “motor” of multiple organ dysfunction syndrome (MODS). This review serves as an update on new data elucidating the role of the gut as the propagator of organ failure in critical illness. Recent findings Under basal conditions, the gut absorbs nutrients and serves as a barrier that prevents approximately 40 trillion intraluminal microbes and their products from causing host injury. However, in critical illness, gut integrity is disrupted with hyperpermeability and increased epithelial apoptosis, allowing contamination of extraluminal sites that are ordinarily sterile. These alterations in gut integrity are further exacerbated in the setting of pre-existing co-morbidities. The normally commensal microflora is also altered in critical illness, with increases in microbial virulence and decreases in diversity, which leads to further pathologic responses within the host. Summary All components of the gut are adversely impacted by critical illness. Gut injury can not only propagate local damage, but can also cause distant injury and organ failure. Understanding how the multifaceted components of the gut interact and how these are perturbed in critical illness may play an important role in turning off the “motor” of MODS in the future.

Background and Aims: Intensive care unit acquired weakness (ICUAW) is a common occurrence in patients who are critically ill. It is most often due to critical illness polyneuropathy (CIP) or to critical illness myopathy (CIM). ICUAW is increasingly being recognized partly as a consequence of improved survival in patients with severe sepsis and multi-organ failure, partly related to commonly used agents such as steroids and muscle relaxants. There have been occasional reports of CIP and CIM in children, but little is known about their prevalence or clinical impact in the pediatric population. This review summarizes the current understanding of pathophysiology, clinical presentation, diagnosis and treatment of CIP and CIM in general with special reference to published literature in the pediatric age group. Subjects and Methods: Studies were identified through MedLine and Embase using relevant MeSH and Key words. Both adult and pediatric studies were included. Results: ICUAW in children is a poorly described entity with unknown incidence, etiology and unclear long-term prognosis. Conclusions: Critical illness polyneuropathy and myopathy is relatively rare, but clinically significant sequelae of multifactorial origin affecting morbidity, length of intensive care unit (ICU) stay and possibly mortality in critically ill children admitted to pediatric ICU.

The Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN) is an international collaborative project with the overall objective of standardizing the approach to the evaluation and treatment of critically ill patients world-wide, in accordance with best-practice principles. One of CERTAIN's key features is clinical decision support providing point-of-care information about common acute illness syndromes, procedures, and medications in an index card format. This paper describes 1) the process of developing and validating the content for point-of-care decision support, and 2) the content management system that facilitates frequent peer-review and allows rapid updates of content across different platforms (CERTAIN software, mobile apps, pdf-booklet) and different languages. Content was created based on survey results of acute care providers and validated using an open peer-review process. Over a 3 year period, CERTAIN content expanded to include 67 syndrome cards, 30 procedure cards, and 117 medication cards. 127 (59 %) cards have been peer-reviewed so far. Initially MS Word® and Dropbox® were used to create, store, and share content for peer-review. Recently Google Docs® was used to make the peer-review process more efficient. However, neither of these approaches met our security requirements nor has the capacity to instantly update the different CERTAIN platforms. Although we were able to successfully develop and validate a large inventory of clinical decision support cards in a short period of time, commercially available software solutions for content management are suboptimal. Novel custom solutions are necessary for efficient global point of care content system management.

Antioxidant Vitamins and Trace Elements in Critical Illness.

PubMed

Koekkoek, W A C Kristine; van Zanten, Arthur R H

2016-08-01

This comprehensive narrative review summarizes relevant antioxidant mechanisms, the antioxidant status, and effects of supplementation in critically ill patients for the most studied antioxidant vitamins A, C, and E and the enzyme cofactor trace elements selenium and zinc. Over the past 15 years, oxidative stress-mediated cell damage has been recognized to be fundamental to the pathophysiology of various critical illnesses such as acute respiratory distress syndrome, ischemia-reperfusion injury, and multiorgan dysfunction in sepsis. Related to these conditions, low plasma levels of antioxidant enzymes, vitamins, and trace elements have been frequently reported, and thus supplementation seems logical. However, low antioxidant plasma levels per se may not indicate low total body stores as critical illness may induce redistribution of antioxidants. Furthermore, low antioxidant levels may even be beneficial as pro-oxidants are essential in bacterial killing. The reviewed studies in critically ill patients show conflicting results. This may be due to different patient populations, study designs, timing, dosing regimens, and duration of the intervention and outcome measures evaluated. Therefore, at present, it remains unclear whether supplementation of antioxidant micronutrients has any clinical benefit in critically ill patients as some studies show clear benefits, whereas others demonstrate neutral outcomes and even harm. Combination therapy of antioxidants seems logical as they work in synergy and function as elements of the human antioxidant network. Further research should focus on defining the normal antioxidant status for critically ill patients and to study optimal supplement combinations either by nutrition enrichment or by enteral or parenteral pharmacological interventions. © 2016 American Society for Parenteral and Enteral Nutrition.

Pressure ulcer incidence and progression in critically ill subjects: influence of low air loss mattress versus a powered air pressure redistribution mattress.

2012-01-01

The primary objective of this study was to compare facility-acquired pressure ulcer incidence and progression of pressure ulcers present on admission in critically ill patients, using 2 different support surfaces. We completed a comparison cohort study in a surgical intensive care unit (ICU). The study setting was a 12-bed cardiovascular ICU in a university-based hospital in the Midwestern United States. The sample comprised 52 critically ill patients; 31 were placed on low air loss weight-based pressure redistribution-microclimate management system beds and 21 were placed on integrated powered air pressure redistribution beds. Prior to the start of the study, 5 low airloss beds were placed in open rooms in the cardiovascular surgical ICU. Inclusion criteria were anticipated ICU stay of 3 days, and patients did not receive a speciality bed for pulmonary or wound issues. Initial assessment of the patients included risk assessment and prior events that would increase risk for pressure ulcer development such as extended time in operating room, along with skin assessment for existing pressure ulcers. Subjects in both groups had ongoing skin assessment every 3 to 4 days and a subjective evaluation of heel elevation and turning or repositioning by the researcher. Data were collected until the subjects were dismissed from the ICU. Patients admitted to the unit were assigned to open rooms following the usual protocols. The mean length of stay was 7.0 days, with an 8.1-day length of stay for subjects on "low air loss with microclimate management" beds (LAL-MCM) and 6.6 days on the integrated power pressure air redistribution (IP-AR) beds (P = NS). The incidence of pressure ulcers on the buttocks, sacrum, or coccyx was 0% (0/31) on the low air loss bed and 18% (4/21) on the IP-AR bed (P = .046). Five subjects had 6 pressure ulcers on admission. Two pressure ulcers on 2 patients worsened on the integrated power air redistribution beds, which required specialty bed rental costing the facility $4116. No subjects on the low air loss beds experienced worsening of existing pressure ulcer. One patient with a deep tissue injury present on admission improved on the LAL-MCM bed. The IP-AR beds were approximately 7 years old, and the LAL-MCM beds were new. Critically ill subjects placed on low air loss beds with microclimate management in surgical ICUs had a lower pressure ulcer incidence than those placed on integrated powered air pressure redistribution beds. The clinical performance of the IP-AR surfaces may have been influenced by their age.

Impact of shift work on critical care nurses.

Pryce, Cheryl

2016-01-01

Shift work is a common practice in the health care field to maintain 24-hour patient care. The purpose of this article is to recognize the negative impact of shift work on critical care nurses, and identify strategies to mitigate these effects. A review of the literature was completed, using the search terms: 'shift work, 'critical care', impact, and health. The literature revealed that shift work has an adverse effect on the health of a nurse. Some of the health implications include stress, sleep deprivation, cardiovascular disease, gastrointestinal symptoms, and mental health illnesses. Furthermore, shift work impacts a nurse's social life and may result in patient harm. Strategies to reduce the negative impact of shift work will be focused on educating critical care nurses and managers. These strategies include frontline staff maintaining a moderate amount of exercise, sustaining a well-balanced diet, using relaxation techniques, reducing the use of cigarettes, working an eight-hour work day, and napping during scheduled breaks. Recommendations for managers include implementing quiet time at the workplace, providing a safe space for staff to nap during breaks, facilitating an eight-hour work day, and encouraging a multidisciplinary team approach when managing workload.

The epidemiology of chronic critical illness is not well characterized. We sought to determine the prevalence, outcomes, and associated costs of chronic critical illness in the United States. Population-based cohort study using data from the United States Healthcare Costs and Utilization Project from 2004 to 2009. Acute care hospitals in Massachusetts, North Carolina, Nebraska, New York, and Washington. Adult and pediatric patients meeting a consensus-derived definition for chronic critical illness, which included one of six eligible clinical conditions (prolonged acute mechanical ventilation, tracheotomy, stroke, traumatic brain injury, sepsis, or severe wounds) plus at least 8 days in an ICU. None. Out of 3,235,741 admissions to an ICU during the study period, 246,151 (7.6%) met the consensus definition for chronic critical illness. The most common eligibility conditions were prolonged acute mechanical ventilation (72.0% of eligible admissions) and sepsis (63.7% of eligible admissions). Among patients meeting chronic critical illness criteria through sepsis, the infections were community acquired in 48.5% and hospital acquired in 51.5%. In-hospital mortality was 30.9% with little change over the study period. The overall population-based prevalence was 34.4 per 100,000. The prevalence varied substantially with age, peaking at 82.1 per 100,000 individuals 75-79 years old but then declining coincident with a rise in mortality before day 8 in otherwise eligible patients. Extrapolating to the entire United States, for 2009, we estimated a total of 380,001 cases; 107,880 in-hospital deaths and $26 billion in hospital-related costs. Using a consensus-based definition, the prevalence, hospital mortality, and costs of chronic critical illness are substantial. Chronic critical illness is particularly common in the elderly although in very old patients the prevalence declines, in part because of an increase in early mortality among potentially eligible patients.

Recent impactful additions to the professional literature on the role of pharmacotherapy in treating the critically ill are summarized. An unusually large number of updated practice guidelines and other publications with broad critical care pharmacotherapy ramifications appeared in the primary biomedical literature during the designated review period (February 2012-February 2013). Hundreds of relevant articles were evaluated by the Critical Care Pharmacotherapy Literature Update group (CCPLU), a national group of pharmacists who routinely monitor 25 peer-reviewed journals for emerging evidence that pertains to rational medication use in the intensive care unit (ICU) setting. From among those articles, 64 were summarized for dissemination to CCPLU members; the 8 publications deemed to have the greatest utility for critical care practitioners, as determined by CCPLU through a voting process, were selected for inclusion in this review, with preference given to evidence meeting high standards of methodological quality. The summaries presented here include (1) important new recommendations on management of pain, agitation, and delirium in critically ill patients, (2) a comprehensive update of a practice guideline issued in 2008 by the Surviving Sepsis Campaign, (3) novel strategies for the prevention and/or treatment of hyperglycemia in critical care, and (4) reports on clinical trials of promising alternative methods of sedation for use in weaning patients from mechanical ventilation. This review provides synopses of practice guidelines and other recent additions to the professional literature pertaining to rational medication use in the ICU practice setting.

Acute kidney injury (AKI) is a common and serious complication in patients in the Pediatric Intensive Care Unit (PICU). We conducted this study to estimate the incidence and the mortality rate of AKI in critically ill children as well as to describe some other related factors. A retrospective study was conducted at PICU of Queen Rania Abdulla Children Hospital, Amman, Jordan for the period extending from May 2011 to June 2013. The medical records of all patients admitted during this period, and their demographic data were reviewed. Patients with AKI were identified, and management and outcomes were reviewed and analyzed. AKI was evaluated according to modified RIFLE criteria. Of the 372 patients admitted to PICU, 64 (17.2%) patients developed AKI. Of these 64 patients who had AKI, 28 (43.7%) patients reached RIFLE max of risk, 21 (32.8%) patients reached injury, and 15 (23.4%) reached failure. Mean Pediatric Risk of Mortality II score at admission was significantly higher in patients with AKI than those without P <0.001. The age ranged between one month and 14 years with the median age as 5.4 year. Thirty-five (54.7%) were males. Sepsis was the most common cause of AKI. The mortality rate in critically ill children without AKI was 58.7%, whereas increased in children with AKI to 73.4%. The mortality rate in patients who received renal replacement therapy was 71.4% and was higher (81.5%) in patients who received mechanical ventilation (95%, [confidence interval (CI)] 79.3-83.4%) and was significantly higher in patients with multi-organ system dysfunction 90.3% (95%, [CI] 88.7-92.5%). The incidence of AKI in critically ill children is high and increased their mortality rate and higher mortality seen in the younger age group, especially those below one year. High mortality rate was associated with multi-organ system dysfunction and the need for mechanical ventilation.

Refeeding syndrome comprises metabolic disturbances that occur after the reintroduction of feeding after prolonged fasting. Standard care consists of correcting fluid and electrolytes imbalances. Energy intake during refeeding syndrome is heavily debated. This study addresses the effect of caloric intake on outcome during the management of refeeding syndrome. A retrospective study among critically ill invasive mechanically ventilated patients admitted for >7 days to a medical-surgical ICU. Refeeding syndrome was diagnosed by the occurrence of new onset hypophosphatemia (<0.65 mmol/l) within 72 h of the start of nutritional support. Primary outcome was 6-month mortality. Secondary outcomes were 3-month mortality, ICU and hospital length of stay and duration of mechanical ventilation. Outcomes of patients with and without refeeding syndrome were compared and subgroup analysis on energy intake within the refeeding population was performed for the duration of survival. Of 337 enrolled patients, 124 (36.8%) developed refeeding syndrome and 213 patients (63.2%) maintained normal serum phosphate levels. Between the two groups, no statistical significant differences in clinical outcomes were observed. Within the refeeding syndrome group, a reduced 6-month mortality risk for low caloric intake (<50% of target) was seen compared with normal intake, adjusted Hazard Ratio 0.39, (95% CI 0.16-0.95, p = 0.037). In this group, low caloric intake was associated with an increased overall survival time at day 180 (153.0 (SE 10.1) vs 119.1 (SE 8.0) days, log-rank p = 0.018). Refeeding syndrome is common among prolonged mechanically ventilated critically ill patients, however not predictable by baseline characteristics. Among patients that develop refeeding syndrome low caloric intake was associated with a reduction in 6-month mortality risk. This effect was not seen in patients without refeeding syndrome. Findings support caloric restriction in refeeding syndrome during critical illness. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

To examine the frequency of acute stress disorder and posttraumatic stress disorder in chronically critically ill patients with a specific focus on severe sepsis, to classify different courses of stress disorders from 4 weeks to 6 months after transfer from acute care hospital to postacute rehabilitation, and to identify patients at risk by examining the relationship between clinical, demographic, and psychological variables and stress disorder symptoms. Prospective longitudinal cohort study, three assessment times within 4 weeks, 3 months, and 6 months after transfer to postacute rehabilitation. Patients were consecutively enrolled in a large rehabilitation hospital (Clinic Bavaria, Kreischa, Germany) admitted for ventilator weaning from acute care hospitals. We included 90 patients with admission diagnosis critical illness polyneuropathy or critical illness myopathy with or without severe sepsis, age between 18 and 70 years with a length of ICU stay greater than 5 days. None. Acute stress disorder and posttraumatic stress disorder were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, criteria by a trained and experienced clinical psychologist using a semistructured clinical interview for Diagnostic and Statistical Manual of Mental Disorders. We further administered the Acute Stress Disorder Scale and the Posttraumatic Symptom Scale-10 to assess symptoms of acute stress disorder and posttraumatic stress disorder. Three percent of the patients had an acute stress disorder diagnosis 4 weeks after transfer to postacute rehabilitation. Posttraumatic stress disorder was found in 7% of the patients at 3-month follow-up and in 12% after 6 months, respectively. Eighteen percent of the patients showed a delayed onset of posttraumatic stress disorder. Sepsis turned out to be a significant predictor of posttraumatic stress disorder symptoms at 3-month follow-up. A regular screening of post-ICU patients after discharge from hospital should be an integral part of aftercare management. The underlying mechanisms of severe sepsis in the development of posttraumatic stress disorder need further examination.

Nutrition: A Primary Therapy in Pediatric Acute Respiratory Distress Syndrome

PubMed Central

Wilson, Bryan; Typpo, Katri

2016-01-01

Appropriate nutrition is an essential component of intensive care management of children with acute respiratory distress syndrome (ARDS) and is linked to patient outcomes. One out of every two children in the pediatric intensive care unit (PICU) will develop malnutrition or have worsening of baseline malnutrition and present with specific micronutrient deficiencies. Early and adequate enteral nutrition (EN) is associated with improved 60-day survival after pediatric critical illness, and, yet, despite early EN guidelines, critically ill children receive on average only 55% of goal calories by PICU day 10. Inadequate delivery of EN is due to perceived feeding intolerance, reluctance to enterally feed children with hemodynamic instability, and fluid restriction. Underlying each of these factors is large practice variation between providers and across institutions for initiation, advancement, and maintenance of EN. Strategies to improve early initiation and advancement and to maintain delivery of EN are needed to improve morbidity and mortality from pediatric ARDS. Both, over and underfeeding, prolong duration of mechanical ventilation in children and worsen other organ function such that precise calorie goals are needed. The gut is thought to act as a “motor” of organ dysfunction, and emerging data regarding the role of intestinal barrier functions and the intestinal microbiome on organ dysfunction and outcomes of critical illness present exciting opportunities to improve patient outcomes. Nutrition should be considered a primary rather than supportive therapy for pediatric ARDS. Precise nutritional therapies, which are titrated and targeted to preservation of intestinal barrier function, prevention of intestinal dysbiosis, preservation of lean body mass, and blunting of the systemic inflammatory response, offer great potential for improving outcomes of pediatric ARDS. In this review, we examine the current evidence regarding dose, route, and timing of nutrition, current recommendations for provision of nutrition to children with ARDS, and the current literature for immune-modulating diets for pediatric ARDS. We will examine emerging data regarding the role of the intestinal microbiome in modulating the response to critical illness. PMID:27790606

To identify risk factors for failure of anticoagulant thromboprophylaxis in critically ill patients in the ICU. Multivariable regression analysis of thrombosis predictors from a randomized thromboprophylaxis trial. Sixty-seven medical-surgical ICUs in six countries. Three thousand seven hundred forty-six medical-surgical critically ill patients. All patients received anticoagulant thromboprophylaxis with low-molecular-weight heparin or unfractionated heparin at standard doses. Independent predictors for venous thromboembolism, proximal leg deep vein thrombosis, and pulmonary embolism developing during critical illness were assessed. A total of 289 patients (7.7%) developed venous thromboembolism. Predictors of thromboprophylaxis failure as measured by development of venous thromboembolism included a personal or family history of venous thromboembolism (hazard ratio, 1.64; 95% CI, 1.03-2.59; p = 0.04) and body mass index (hazard ratio, 1.18 per 10-point increase; 95% CI, 1.04-1.35; p = 0.01). Increasing body mass index was also a predictor for developing proximal leg deep vein thrombosis (hazard ratio, 1.25; 95% CI, 1.06-1.46; p = 0.007), which occurred in 182 patients (4.9%). Pulmonary embolism occurred in 47 patients (1.3%) and was associated with body mass index (hazard ratio, 1.37; 95% CI, 1.02-1.83; p = 0.035) and vasopressor use (hazard ratio, 1.84; 95% CI, 1.01-3.35; p = 0.046). Low-molecular-weight heparin (in comparison to unfractionated heparin) thromboprophylaxis lowered pulmonary embolism risk (hazard ratio, 0.51; 95% CI, 0.27-0.95; p = 0.034) while statin use in the preceding week lowered the risk of proximal leg deep vein thrombosis (hazard ratio, 0.46; 95% CI, 0.27-0.77; p = 0.004). Failure of standard thromboprophylaxis using low-molecular-weight heparin or unfractionated heparin is more likely in ICU patients with elevated body mass index, those with a personal or family history of venous thromboembolism, and those receiving vasopressors. Alternate management or incremental risk reduction strategies may be needed in such patients.

Hospital-Based Physicians' Intubation Decisions and Associated Mental Models when Managing a Critically and Terminally Ill Older Patient.

Variation in the intensity of acute care treatment at the end of life is influenced more strongly by hospital and provider characteristics than patient preferences. We sought to describe physicians' mental models (i.e., thought processes) when encountering a simulated critically and terminally ill older patient, and to compare those models based on whether their treatment plan was patient preference-concordant or preference-discordant. Seventy-three hospital-based physicians from 3 academic medical centers engaged in a simulated patient encounter and completed a mental model interview while watching the video recording of their encounter. We used an "expert" model to code the interviews. We then used Kruskal-Wallis tests to compare the weighted mental model themes of physicians who provided preference-concordant treatment with those who provided preference-discordant treatment. Sixty-six (90%) physicians provided preference-concordant treatment and 7 (10%) provided preference-discordant treatment (i.e., they intubated the patient). Physicians who intubated the patient were more likely to emphasize the reversible and emergent nature of the patient situation (z = -2.111, P = 0.035), their own comfort (z = -2.764, P = 0.006), and rarely focused on explicit patient preferences (z = 2.380, P = 0.017). Post-decisional interviewing with audio/video prompting may induce hindsight bias. The expert model has not yet been validated and may not be exhaustive. The small sample size limits generalizability and power. Hospital-based physicians providing preference-discordant used a different mental model for decision making for a critically and terminally ill simulated case. These differences may offer targets for future interventions to promote preference-concordant care for seriously ill patients.

Does artificial nutrition improve outcome of critical illness? An alternative viewpoint!

PubMed

Heyland, Daren K; Wischmeyer, Paul E

2013-08-27

Recent studies challenge the beneficial role of artificial nutrition provided to critically ill patients and point out the limitations of existing studies in this area. We take a differing view of the existing data and refute many of the arguments put forward by previous authors. We review the mechanistic, observational, and experimental data supporting a role for early enteral nutrition in the critically ill patient. We conclude without question that more, high-quality research is needed to better define the role of artificial nutrition in the critical care setting, but until then early and adequate delivery of enteral nutrition is a legitimate, evidence-based treatment recommendation and we see no evidence-based role for restricting enteral nutrition in critically ill patients. The role of early supplemental parenteral nutrition continues to be defined as new data emerge.

Sickness absence management: encouraging attendance or 'risk-taking' presenteeism in employees with chronic illness?

PubMed

Munir, Fehmidah; Yarker, Joanna; Haslam, Cheryl

2008-01-01

To investigate the organizational perspectives on the effectiveness of their attendance management policies for chronically ill employees. A mixed-method approach was employed involving questionnaire survey with employees and in-depth interviews with key stakeholders of the organizational policies. Participants reported that attendance management polices and the point at which systems were triggered, posed problems for employees managing chronic illness. These systems presented risk to health: employees were more likely to turn up for work despite feeling unwell (presenteeism) to avoid a disciplinary situation but absence-related support was only provided once illness progressed to long-term sick leave. Attendance management polices also raised ethical concerns for 'forced' illness disclosure and immense pressures on line managers to manage attendance. Participants felt their current attendance management polices were unfavourable toward those managing a chronic illness. The policies heavily focused on attendance despite illness and on providing return to work support following long-term sick leave. Drawing on the results, the authors conclude that attendance management should promote job retention rather than merely prevent absence per se. They outline areas of improvement in the attendance management of employees with chronic illness.

Post-Polio Syndrome (PPS) is characterized by new muscle weakness and/or muscle fatigability that occurs many years following the initial poliomyelitis illness. An individualized approach to rehabilitation management is critical. Interventions may include rehabilitation management strategies, adaptive equipment, orthotic equipment, gait/mobility aids and a variety of therapeutic exercises. The progression of muscle weakness in PPS is typically slow and gradual; however, there is also variability in both the natural history of weakness and functional prognosis. Further research is required to determine the effectiveness of selected medical treatment. This article is protected by copyright. All rights reserved. © 2018 Wiley Periodicals, Inc.

Chronic conditions can affect school-age children in more ways than just physically. Normal childhood maturation is critical at this age, yet daily management of chronic symptoms can be challenging. This article describes 4 common childhood chronic illnesses (asthma, seizure disorders, diabetes, and cystic fibrosis), and the impact these conditions have on the developing child. Self-efficacy, the belief that one can effectively perform necessary skills, is essential to self-management of chronic conditions and contributes in a positive way to the child's normal development. Implications for clinical practice and future research are discussed. Copyright © 2013 Elsevier Inc. All rights reserved.

Early detection of disease outbreaks is critical for disease spread control and management. In this work we investigate the suitability of statistical machine learning approaches to automatically detect Twitter messages (tweets) that are likely to report cases of possible influenza like illnesses (ILI). Empirical results obtained on a large set of tweets originating from the state of Victoria, Australia, in a 3.5 month period show evidence that machine learning classifiers are effective in identifying tweets that mention possible cases of ILI (up to 0.736 F-measure, i.e. the harmonic mean of precision and recall), regardless of the specific technique implemented by the classifier investigated in the study.

For most critically ill patients requiring mechanical ventilation in the intensive care unit (ICU) weaning is uncomplicated. For the remainder, weaning is a challenge and may result in further complications and increased risk of mortality. Critical care nurses (CCNs) require substantial knowledge and experience to manage patients experiencing prolonged weaning. The aim of this study was to explore CCNs approach for management of patients experiencing prolonged weaning in the ICU. A descriptive qualitative design. Semi-structured interviews with 19 experienced CCNs were conducted. Data were analysed using content analysis. Participants used various strategies for weaning that were grouped into four categories: individualized planning for the weaning process, assessing patient's capacity, managing the process and team interaction. The overall theme that emerged was: CCNs drive the weaning process using both a patient centred and targeted approach. CCNs in these ICUs performed weaning using a patient centred approach to plan, initiate, assess and establish a holistic weaning process. Team collaboration among all health care practitioners was important. CCNs have a key role in prioritizing weaning and driving the process forward. Closeness to the patient and a key role in management of the mechanical ventilated patient in ICU gives the CCN unique potential to develop and create models and tools for prolonged weaning. These tools, specially designed for patients undergoing prolonged weaning, would give focus on continuous planning, collaborating, managing and evaluation in the process of liberating patients from mechanical ventilation. © 2014 British Association of Critical Care Nurses.

Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Symptom Severity: Stress Management Skills are Related to Lower Illness Burden.

The onset of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) typically involves reductions in activities of daily living and social interactions (jointly referred to as "illness burden"). Emotional distress has been linked to increased reported symptoms, and stress management skills have been related to lower fatigue severity in CFS patients. Symptom severity and illness burden are highly correlated. The ability to manage stress may attenuate this relationship, allowing individuals to feel less burdened by the illness independent of the severity of their symptoms. This study aimed to evaluate if perceived stress management skills affect illness burden via emotional distress, independent of ME/CFS symptom severity. A total of 117 adults with ME/CFS completed measures of perceived stress management skills, emotional distress, ME/CFS symptom severity and illness burden. Regression analyses revealed that greater perceived stress management skills related to less social and fatigue-related illness burden, via lower emotional distress. This relationship existed independent of the association of symptom severity on illness burden, and was stronger among those not currently employed. Ability to manage stress is associated with a lower illness burden for individuals with ME/CFS. Future studies should evaluate the efficacy of psychosocial interventions in lowering illness burden by targeting stress management skills.

Measuring and Predicting Long-Term Outcomes in Older Survivors of Critical Illness

Baldwin, Matthew R.

2015-01-01

Older adults (age ≥65 years) now initially survive what were previously fatal critical illnesses, but long-term mortality and disability after critical illness remain high. Most studies show that the majority of deaths among older ICU survivors occur during the first 6 to 12 months after hospital discharge. Recent studies of older ICU survivors have created a new standard for longitudinal critical care outcomes studies with a systematic evaluation of pre-critical illness comorbidities and disability and detailed assessments of physical and cognitive function after hospital discharge. These studies show that after controlling for pre-morbid health, older ICU survivors experience large and persistent declines in cognitive and physical function after critical illness. Long-term health-related quality-of-life studies suggest that some older ICU survivors may accommodate to a degree of physical disability and still report good emotional and social well-being, but these studies are subject to survivorship and proxy-response bias. In order to risk-stratify older ICU survivors for long-term (6–12 month) outcomes, we will need a paradigm shift in the timing and type of predictors measured. Emerging literature suggests that the initial acuity of critical illness will be less important, whereas pre-hospitalization estimates of disability and frailty, and, in particular, measures of comorbidity, frailty, and disability near the time of hospital discharge will be essential in creating reliable long-term risk-prediction models.

Short- and long-term impact of critical illness on relatives: literature review.

PubMed

Paul, Fiona; Rattray, Janice

2008-05-01

This paper is a report of a literature review undertaken to identify the short- and long-term impact of critical illness on relatives. Patients in intensive care can experience physical and psychological consequences, and their relatives may also experience such effects. Although it is recognized that relatives have specific needs, it is not clear whether these needs are always met and whether further support is required, particularly after intensive care. The following databases were searched for the period 1950-2007: Medline, British Nursing Index and Archive, EMBASE, CINAHL, PsycINFO and EMB Reviews--Cochrane Central Register of Clinical Trials. Search terms focused on adult relatives of critically ill adult patients during and after intensive care. Recurrent topics were categorized to structure the review, i.e. 'relatives needs', 'meeting relatives' needs', 'interventions', 'satisfaction', 'psychological outcomes' and 'coping'. Studies have mainly identified relatives' immediate needs using the Critical Care Family Needs Inventory. There are few studies of interventions to meet relatives' needs and the short- and long-term effects of critical illness on relatives. Despite widespread use of the Critical Care Family Needs Inventory, factors such as local or cultural differences may influence relatives' needs. Relatives may also have unidentified needs, and these needs should be explored. Limited research has been carried out into interventions to meet relatives' needs and the effects of critical illness on their well-being, yet some relatives may experience negative psychological consequences far beyond the acute phase of the illness.

Background In the coming years, the number of survivors of critical illness is expected to increase. These survivors frequently develop newly acquired physical and cognitive impairments. Long-term cognitive impairment is common following critical illness and has dramatic effects on patients' abilities to function autonomously. Neuromuscular weakness affects similar proportions of patients and leads to equally profound life alterations. As knowledge of these short-term and long-term consequences of critical illness has come to light, interventions to prevent and rehabilitate these devastating consequences have been sought. Physical rehabilitation has been shown to improve functional outcomes in people who are critically ill, but subsequent studies of physical rehabilitation after hospital discharge have not. Post-hospital discharge cognitive rehabilitation is feasible in survivors of critical illness and is commonly used in people with other forms of acquired brain injury. The feasibility of early cognitive therapy in people who are critically ill remains unknown. Objective The purpose of this novel protocol trial will be to determine the feasibility of early and sustained cognitive rehabilitation paired with physical rehabilitation in patients who are critically ill from medical and surgical intensive care units. Design This is a randomized controlled trial. Setting The setting for this trial will be medical and surgical intensive care units of a large tertiary care referral center. Patients The participants will be patients who are critically ill with respiratory failure or shock. Intervention Patients will be randomized to groups receiving usual care, physical rehabilitation, or cognitive rehabilitation plus physical rehabilitation. Twice-daily cognitive rehabilitation sessions will be performed with patients who are noncomatose and will consist of orientation, memory, and attention exercises (eg, forward and reverse digit spans, matrix puzzles, letter-number sequences, pattern recognition). Daily physical rehabilitation sessions will advance patients from passive range of motion exercises through ambulation. Patients with cognitive or physical impairment at discharge will undergo a 12-week, in-home cognitive rehabilitation program. Measurements A battery of neurocognitive and functional outcomes will be measured 3 and 12 months after hospital discharge. Conclusions If feasible, these interventions will lay the groundwork for a larger, multicenter trial to determine their efficacy. PMID:22577067

Implementation strategies in pediatric neurocritical care.

2017-06-01

Brain-directed critical care for children is a relatively new area of subspecialization in pediatric critical care. Pediatric neurocritical care teams combine the expertise of neurology, neurosurgery, and critical care medicine. The positive impact of delivering specialized care to pediatric patients with acute neurological illness is becoming more apparent, but the optimum way to implement and sustain the delivery of this is complicated and poorly understood. We aim to provide emerging evidence supporting that effective implementation of pediatric neurocritical care pathways can improve patient survival and outcomes. We also provide an overview of the most effective strategies across the field of implementation science that can facilitate deployment of neurocritical care pathways in the pediatric ICU. Implementation strategies can broadly be grouped according to six categories: planning, educating, restructuring, financing, managing quality, and attending to the policy context. Using a combination of these strategies in the last decade, several institutions have improved patient morbidity and mortality. Although much work remains to be done, emerging evidence supports that implementation of evidence-based care pathways for critically ill children with two common neurological diagnoses - status epilepticus and traumatic brain injury - improves outcomes. Pediatric and neonatal neurocritical care programs that support evidence-based care can be effectively structured using appropriately sequenced implementation strategies to improve outcomes across a variety of patient populations and in a variety of healthcare settings.

US military Critical Care Air Transport Teams (CCATT) transport critically ill burn patients out of theater. Blood transfusion may incur adverse effects, and studies report lower hemoglobin (Hgb) value may be safe for critically ill patients. There are no studies evaluating the optimal Hgb value for critically ill burn patients prior to CCATT evacuation. The aim of the study was to determine if critically ill burn casualties with an Hgb of 10 g/dL or less, transported via CCATT, have similar clinical outcomes at 30 days as compared with patients with an Hgb of greater than 10 g/dL. We conducted an institutional review board-approved retrospective cohort study involving patients transported via CCATT. We separated our study population into two cohorts based on Hgb levels at the time of theater evacuation: Hgb ≤10 g/dL or Hgb ≥10 g/dL. We compared demographics, injury description, physiologic parameters, and clinical outcomes. Of the 140 subjects enrolled, 29 were Hgb ≤10, and 111 were Hgb ≥10. Both groups were similar in age and percent total body surface area burned. Those Hgb ≤10 had a higher injury severity score (34 ± 19.8 vs. 25 ± 16.9, P = 0.02) and were more likely to have additional trauma (50% vs. 25%, P = 0.04). Modeling revealed no persistent differences in mortality, and other clinical outcomes measured. Critical Care Air Transport Teams transport of critically ill burn patients with an Hgb of 10 g/dL or less had no significant differences in complications or mortality as compared with patients with an Hgb of greater than 10 g/dL. In this study, lower hemoglobin levels did not confer greater risk for worse outcomes.

The normal body exists in mutualistic balance with a large range of microbiota. The primary goal of this study was to establish whether there is an imbalance in the oropharyngeal flora early after hospital or ICU admittance, and whether flora differs between control, ward and critically ill patients. The secondary goal was to explore whether there are patient characteristics that can be associated with a disturbed oropharyngeal flora. Oropharyngeal cultures were obtained from three different study groups: (1) controls from the community, (2) ward patients and (3) critically ill patients, the two latter within 24 h after admittance. Cultures were obtained from 487 individuals: 77 controls, 193 ward patients and 217 critically ill patients. Abnormal pharyngeal flora was more frequent in critically ill and ward patients compared with controls (62.2% and 10.4% vs. 1.3%, P < 0.001 and P = 0.010, respectively). Colonisation of gut flora in the oropharynx was more frequent in critically ill patients compared with ward patients or controls (26.3% vs. 4.7% and 1.3%, P < 0.001 and P < 0.001, respectively). Proton pump inhibitor medication was the strongest independent factor associated with the presence of gut flora in the oropharynx in both ward and critically ill patients (P = 0.030 and P = 0.044, respectively). This study indicates that abnormal oropharyngeal flora is an early and frequent event in hospitalised patients and more so in the critically ill, compared to controls.

Exercise rehabilitation following hospital discharge in survivors of critical illness: an integrative review

PubMed Central

2012-01-01

Although clinical trials have shown benefit from early rehabilitation within the ICU, rehabilitation of patients following critical illness is increasingly acknowledged as an area of clinical importance. However, despite recommendations from published guidelines for rehabilitation to continue following hospital discharge, there is limited evidence to underpin practice during this intermediate stage of recovery. Those patients with ICU-acquired weakness on discharge from the ICU are most likely to benefit from ongoing rehabilitation. Despite this, screening based on strength alone may fail to account for the associated level of physical functioning, which may not correlate with muscle strength, nor address non-physical complications of critical illness. The aim of this review was to consider which patients are likely to require rehabilitation following critical illness and to perform an integrative review of the available evidence of content and nature of exercise rehabilitation programmes for survivors of critical illness following hospital discharge. Literature databases and clinical trials registries were searched using appropriate terms and groups of terms. Inclusion criteria specified the reporting of rehabilitation programmes for patients following critical illness post-hospital discharge. Ten items, including data from published studies and protocols from trial registries, were included. Because of the variability in study methodology and inadequate level of detail of reported exercise prescription, at present there can be no clear recommendations for clinical practice from this review. As this area of clinical practice remains in its relative infancy, further evidence is required both to identify which patients are most likely to benefit and to determine the optimum content and format of exercise rehabilitation programmes for patients following critical illness post-hospital discharge.

Background: Arginine is considered an essential amino acid during critical illness in children, and supplementation of arginine has been proposed to improve arginine availability to facilitate nitric oxide (NO) synthesis. Protein-energy–enriched enteral formulas (PE-formulas) can improve nutrient intake and promote anabolism in critically ill infants. However, the effect of increased protein and energy intake on arginine metabolism is not known. Objective: We investigated the effect of a PE-formula compared with that of a standard infant formula (S-formula) on arginine kinetics in critically ill infants. Design: A 2-h stable-isotope tracer protocol was conducted in 2 groups of critically ill infants with respiratory failure because of viral bronchiolitis, who received either a PE-formula (n = 8) or S-formula (n = 10) in a randomized, blinded, controlled setting. Data were reported as means ± SDs. Results: The intake of a PE-formula in critically ill infants (aged 0.23 ± 0.14 y) resulted in an increased arginine appearance (PE-formula: 248 ± 114 μmol · kg−1 · h−1; S-formula: 130 ± 53 μmol · kg−1 · h−1; P = 0.012) and NO synthesis (PE-formula: 1.92 ± 0.99 μmol · kg−1 · h−1; S-formula: 0.84 ± 0.36 μmol · kg−1 · h−1; P = 0.003), whereas citrulline production and plasma arginine concentrations were unaffected. Conclusion: In critically ill infants with respiratory failure because of viral bronchiolitis, the intake of a PE-formula increases arginine availability by increasing arginine appearance, which leads to increased NO synthesis, independent of plasma arginine concentrations. This trial was registered at www.trialregister.nl as NTR515. PMID:23945723

Growing evidence suggests that critical illness often results in significant long-term neurocognitive impairments in one-third of survivors. Although these neurocognitive impairments are long-lasting and devastating for survivors, rehabilitation rarely occurs during or after critical illness. Our aim is to describe an early neurocognitive stimulation intervention based on virtual reality for patients who are critically ill and to present the results of a proof-of-concept study testing the feasibility, safety, and suitability of this intervention. Twenty critically ill adult patients undergoing or having undergone mechanical ventilation for ≥24 h received daily 20-min neurocognitive stimulation sessions when awake and alert during their ICU stay. The difficulty of the exercises included in the sessions progressively increased over successive sessions. Physiological data were recorded before, during, and after each session. Safety was assessed through heart rate, peripheral oxygen saturation, and respiratory rate. Heart rate variability analysis, an indirect measure of autonomic activity sensitive to cognitive demands, was used to assess the efficacy of the exercises in stimulating attention and working memory. Patients successfully completed the sessions on most days. No sessions were stopped early for safety concerns, and no adverse events occurred. Heart rate variability analysis showed that the exercises stimulated attention and working memory. Critically ill patients considered the sessions enjoyable and relaxing without being overly fatiguing. The results in this proof-of-concept study suggest that a virtual-reality-based neurocognitive intervention is feasible, safe, and tolerable, stimulating cognitive functions and satisfying critically ill patients. Future studies will evaluate the impact of interventions on neurocognitive outcomes. Trial registration Clinical trials.gov identifier: NCT02078206.

Clinical risk management in mental health: a qualitative study of main risks and related organizational management practices.

Briner, Matthias; Manser, Tanja

A scientific understanding of clinical risk management (CRM) in mental health care is essential for building safer health systems and for improving patient safety. While evidence on patient safety and CRM in physical health care has increased, there is limited research on these issues in mental health care. This qualitative study provides an overview of the most important clinical risks in mental health and related organizational management practices. We conducted in-depth expert interviews with professionals responsible for CRM in psychiatric hospitals. Interviews were transcribed and analyzed applying qualitative content analysis to thematically sort the identified risks. The main concerns for CRM in mental health are a) violence and self-destructive behavior (i.e. protecting patients and staff from other patients, and patients from themselves), b) treatment errors, especially in the process of therapy, and c) risks associated with mental illnesses (e.g. psychosis or depression). This study identified critical differences to CRM in hospitals for physical disorder and challenges specific to CRM in mental health. Firstly, many psychiatric patients do not believe that they are ill and are therefore in hospital against their will. Secondly, staff safety is a much more prominent theme for CRM in mental health care as it is directly related to the specifics of mental illnesses. The current study contributes to the understanding of patient safety and raises awareness for CRM in mental health. The mental health specific overview of central risks and related organizational management practices offers a valuable basis for CRM development in mental health and an addition to CRM in general.

Background Fluid balance is a fundamental management of patients with sepsis, and this study aimed to investigate the impact of cumulative fluid balance on critically ill patients with influenza admitted to an intensive care unit (ICU). Methods This multicenter retrospective cohort study was conducted by the Taiwan Severe Influenza Research Consortium (TSIRC) which includes eight medical centers. Patients with virology-proven influenza infection admitted to ICUs between October 2015 and March 2016 were included for analysis. Results A total of 296 patients were enrolled (mean age: 61.4±15.6 years; 62.8% men), and 92.2% (273/296) of them required mechanical ventilation. In the survivors, the daily fluid balance was positive from day 1 to day 3, and then gradually became negative from day 4 to day 7, whereas daily fluid balance was continuously positive in the non-survivors. Using the cumulative fluid balance from day 1–4 as a cut-off point, we found that a negative cumulative day 1–4 fluid balance was associated with a lower 30-day mortality rate (log-rank test, P = 0.003). To evaluate the impact of shock on this association, we divided the patients into shock and non-shock groups. The positive correlation between negative day 1–4 fluid balance and mortality was significant in the non-shock group (log-rank test, P = 0.008), but not in the shock group (log-rank test, P = 0.396). In a multivariate Cox proportional hazard regression model adjusted for age, sex, cerebrovascular disease, and PaO2/FiO2, day 1–4 fluid balance was independently associated with a higher 30-day mortality rate (aHR 1.088, 95% CI: 1.007–1.174). Conclusions A negative day 1–4 cumulative fluid balance was associated with a lower mortality rate in critically ill patients with influenza. Our findings indicate the critical role of conservative fluid strategy in the management of patients with complicated influenza. PMID:29315320

Preload assessment and optimization is the basic hemodynamic intervention in critically ill. Beside clinical assessment, non-invasive or invasive assessment by measurement of various pressure or volume hemodynamic variables, are helpful for estimation of preload and fluid responsiveness. The use of dynamic variables is useful in particular subgroup of critically ill patients. In patients with inadequate preload, fluid responsiveness and inadequate flow, treatment with crystalloids or colloids is mandatory. When rapid hemodynamic response is necessary colloids are preferred.

Observational studies have linked hypocalcemia with adverse clinical outcome in critically ill patients. However, calcium supplementation has never been formally investigated for its beneficial effect in critically ill patients. To investigate whether calcium supplementation can improve 28-day survival in adult critically ill patients. Secondary analysis of a large clinical database consisting over 30,000 critical ill patients was performed. Multivariable analysis was performed to examine the independent association of calcium supplementation and 28-day morality. Furthermore, propensity score matching technique was employed to investigate the role of calcium supplementation in improving survival. none. Primary outcome was the 28-day mortality. 90-day mortality was used as secondary outcome. A total of 32,551 adult patients, including 28,062 survivors and 4489 non-survivors (28-day mortality rate: 13.8 %) were included. Calcium supplementation was independently associated with improved 28-day mortality after adjusting for confounding variables (hazard ratio: 0.51; 95 % CI 0.47-0.56). Propensity score matching was performed and the after-matching cohort showed well balanced covariates. The results showed that calcium supplementation was associated with improved 28- and 90-day mortality (p < 0.05 for both Log-rank test). In adult critically ill patients, calcium supplementation during their ICU stay improved 28-day survival. This finding supports the use of calcium supplementation in critically ill patients.

Background. The use of inflammatory markers to follow up critically ill patients is controversial. The short time frame, the need for frequent and serial measurement of biomarkers, the presence of soluble receptor and their relatively high cost are the major drawbacks. Our study's objective is to compare the prognostic values of serum TNF-α and SOFA score monitoring in critically ill patients. Patients and Methods. A total of ninety patients were included in the study. Forty-five patients developed septic complication (sepsis group). Forty-five patients were critically ill without evidence of infectious organism (SIRS group). Patients' data include clinical status, central venous pressure, and laboratory analysis were measured. A serum level of TNF-α and SOFA score were monitored. Results. Monitoring of TNF-α revealed significant elevation of TNF-α at 3rd and 5th days of ICU admission in both groups. Monitoring of SOFA score revealed significant elevation of SOFA scores in both groups throughout their ICU stay, particularly in nonsurvivors. Positive predictive ability of SOFA score was demonstrated in critically ill patients. Conclusion. Transient significant increase in serum levels of TNF-α were detected in septic patients. Persistent elevation of SOFA score was detected in nonsurvivor septic patients. SOFA score is an independent prognostic value in critically ill patients. PMID:24175285

Sarcopenia and critical illness: a deadly combination in the elderly.

PubMed

Hanna, Joseph S

2015-03-01

Sarcopenia is the age-associated loss of lean skeletal muscle mass. It is the result of multiple physiologic derangements, ultimately resulting in an insidious functional decline. Frailty, the clinical manifestation of sarcopenia and physical infirmity, is associated with significant morbidity and mortality in the elderly population. The underlying pathology results in a disruption of the individual's ability to tolerate internal and external stressors such as injury or illness. This infirmity results in a markedly increased risk of falls and subsequent morbidity and mortality from the resulting traumatic injury, as well as an inability to recover from medical insults, resulting in critical illness. The increasing prevalence of sarcopenia and critical illness in the elderly has resulted in a deadly intersection of disease processes. The lethality of this combination appears to be the result of altered muscle metabolism, decreased mitochondrial energetics needed to survive critical illness, and a chronically activated catabolic state likely mediated by tumor necrosis factor-α. Furthermore, these underlying derangements are independently associated with an increased incidence of critical illness, resulting in a progressive downward spiral. Considerable evidence has been gathered supporting the role of aggressive nutrition support and physical therapy in improving outcomes. Critical care practitioners must consider sarcopenia and the resulting frailty phenotype a comorbid condition so that the targeted interventions can be instituted and research efforts focused. © 2015 American Society for Parenteral and Enteral Nutrition.

Perforated peptic ulcer disease continues to inflict high morbidity and mortality. Although patients can be stratified according to their surgical risk, optimal management has yet to be described. In this study we demonstrate a treatment option that improves the mortality among critically ill, poor risk patients with perforated peptic ulcer disease. In our study, two series were retrospectively reviewed: group A patients (n = 522) were treated in a single surgical unit at the Dhaka Medical College Hospital, Dhaka, Bangladesh during the 1980s. Among them, 124 patients were stratified as poor risk based on age, delayed presentation, peritoneal contamination, and coexisting medical problems. These criteria were the basis for selecting a group of poor risk patients (n = 84) for minimal surgical intervention (percutaneous peritoneal drainage) out of a larger group of patients, group B (n = 785) treated at Khulna Medical College Hospital during the 1990s. In group A, 479 patients underwent conventional operative management with an operative mortality of 8.97%. Among the 43 deaths, 24 patients were >60 years of age (55.8%), 12 patients had delayed presentation (27.9%), and 7 patients were in shock or had multiple coexisting medical problems (16.2%). In group B, 626 underwent conventional operative management, with 26 deaths at a mortality rate of 4.15%. Altogether, 84 patients were stratified as poor risk and were managed with minimal surgical intervention (percutaneous peritoneal drainage) followed by conservative treatment. Three of these patients died with an operative mortality of 3.5%. Minimal surgical intervention (percutaneous peritoneal drainage) can significantly lower the mortality rate among a selected group of critically ill, poor risk patients with perforated peptic ulcer disease.

The experience of sleep in chronic fatigue syndrome: A qualitative interview study with patients.

Sleep disturbances are common in chronic fatigue syndrome (CFS), and one of the key symptom complaints, yet it has been neglected by previous qualitative research. The aim was to explore the specific role of sleep in patients' experience of their illness. A qualitative semi-structured interview format facilitated a detailed and open exploration of sleep, and the extent to which its management and problems were linked to the lived experience of CFS. Eleven semi-structured interviews were conducted with individuals with CFS. Data were transcribed verbatim and analysed thematically, to explore and describe patients' experience of their sleep, and its impact on their condition. Sleep emerged as a key aspect of the illness experience, and its management and effect on daytime functioning was a central pre-occupation for all 11 participants; all of them saw sleep as playing a critical role in their illness through either maintaining or exacerbating existing symptoms. Exploration of individual experiences presented three overarching themes: (1) sleep pattern variability over illness course and from day to day; (2) effect of sleep on daytime functioning; and (3) attempts at coping and sleep management. Each patient with CFS has a unique experience of sleep. Despite the differing narratives regarding the role of sleep in CFS, all participants held the belief that sleep is a vital process for health and well-being which has had a direct bearing on the course and progression of their CFS. Also, every participant regarded their sleep as in some way 'broken' and in need of management/repair. Patients' insights demonstrate sleep-specific influences on their CFS, and the impact of disturbed sleep should be a consideration for clinical and research work. What is already known on this subject? Sleep disturbances are common in CFS, and one of the key symptom complaints, yet it has been neglected by previous qualitative research. Ontology of CFS is a matter of dispute, with models ranging from the biological to the psychological competing to explain symptomatology in this illness. A qualitative study has the potential to add some clarity to the debate by making the patients' lived experience of the condition, and their own understanding of it, the focus of research. What this study adds? Coping and attempts at managing sleep problems in CFS adds to the 'illness burden' experienced by patients. Disturbed sleep is universally seen by patients with CFS as impacting on other daytime symptoms. Broken sleep may contribute to a biopsychosocial cycle that serves to maintain this illness. © 2015 The British Psychological Society.

Barriers and Facilitators to Smoking Cessation Among People With Severe Mental Illness: A Critical Appraisal of Qualitative Studies.

Trainor, Katie; Leavey, Gerard

2017-01-01

People with severe mental illness (PWSMI) die 15-20 years earlier than people in the general population and this is often due to preventable smoking-related health conditions. Studies that identify barriers and facilitators to smoking cessation are crucial for policy makers and health care professionals. This appraisal aims to identify and critically appraise qualitative studies which explore smoking experiences and barriers to smoking cessation among PWSMI. Articles were retrieved from electronic health related databases including Web of Science, Scopus, PubMed, Sage, Biomed, Medline, Embase, and electronic hand searches of bibliographies from key articles. Eleven papers were identified. Although the overall quality of studies were sufficient, most had limited information relating to trustworthiness and sociodemographic details. Cost savings and health benefits were frequently cited as facilitators to quitting, however may be of limited impact as smoking for existential purposes, social inclusion, and mental health management appear to be considered highly important among PWSMI. Findings were restricted to predominantly individual barriers to smoking cessation which may be more resistant to change as service users rely on smoking to manage their mental health and smoking is embedded in the culture of mental health settings. This critical appraisal identifies qualitative evidence regarding which factors facilitate or prevent individuals with severe mental illness from engaging with smoking cessation. Healthcare professionals and policy makers should address external barriers to quitting smoking as this may increase participation in intervention studies, inform policy and assist in the development of a feasible and acceptable smoking cessation intervention among PWSMI. Methodological considerations highlight that future research should include sociodemographic and contextual factors to improve utility and applicability of findings. © The Author 2016.

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are consistently associated with morbidity and mortality among the critically ill or injured. Thus, avoiding or potentially treating these conditions may improve patient outcomes. With the aim of improving the outcomes for patients with IAH/ACS, the World Society of the Abdominal Compartment Syndrome recently updated its clinical practice guidelines. In this article, we review the association between a positive fluid balance and outcomes among patients with IAH/ACS and how optimisation of fluid administration and systemic/regional perfusion may potentially lead to improved outcomes among this patient population.Evidence consistently associates secondary IAH with a positive fluid balance. However, despite increased research in the area of non-surgical management of patients with IAH and ACS, evidence supporting this approach is limited. Some evidence exists to support implementing goal-directed resuscitation protocols and restrictive fluid therapy protocols in shocked and recovering critically ill patients with IAH. Data from animal experiments and clinical trials has shown that the early use of vasopressors and inotropic agents is likely to be safe and may help reduce excessive fluid administration, especially in patients with IAH. Studies using furosemide and/or renal replacement therapy to achieve a negative fluid balance in patients with IAH are encouraging. The type of fluid to be administered in patients with IAH remains far from resolved. There is currently insufficient evidence to recommend the use of abdominal perfusion pressure as a resuscitation endpoint in patients with IAH. However, it is important to recognise that IAH either abolishes or increases threshold values for pulse pressure variation and stroke volume variation to predict fluid responsiveness, while the presence of IAH may also result in a false negative passive leg raising test.Correct fluid therapy and perfusional support during resuscitation form the cornerstone of medical management in patients with abdominal hypertension. Controlled studies determining whether the above medical interventions may improve outcomes among those with IAH/ACS are urgently required.

Acute brain injury is a common cause of death and critical illness in children and young adults. Fundamental management focuses on early characterization of the extent of injury and optimizing recovery by preventing secondary damage during the days following the primary injury. Currently, bedside technology for measuring neurological function is mainly limited to using electroencephalography (EEG) for detection of seizures and encephalopathic features, and evoked potentials. We present a proof of concept study in patients with acute brain injury in the intensive care setting, featuring a bedside functional imaging set-up designed to map cortical brain activation patterns by combining high density EEG recordings, multi-modal sensory stimulation (auditory, visual, and somatosensory), and EEG source modeling. Use of source-modeling allows for examination of spatiotemporal activation patterns at the cortical region level as opposed to the traditional scalp potential maps. The application of this system in both healthy and brain-injured participants is demonstrated with modality-specific source-reconstructed cortical activation patterns. By combining stimulation obtained with different modalities, most of the cortical surface can be monitored for changes in functional activation without having to physically transport the subject to an imaging suite. The results in patients in an intensive care setting with anatomically well-defined brain lesions suggest a topographic association between their injuries and activation patterns. Moreover, we report the reproducible application of a protocol examining a higher-level cortical processing with an auditory oddball paradigm involving presentation of the patient's own name. This study reports the first successful application of a bedside functional brain mapping tool in the intensive care setting. This application has the potential to provide clinicians with an additional dimension of information to manage critically-ill children and adults, and potentially patients not suited for magnetic resonance imaging technologies.

Respiratory muscle dysfunction: a multicausal entity in the critically ill patient undergoing mechanical ventilation.

Díaz, Magda C; Ospina-Tascón, Gustavo A; Salazar C, Blanca C

2014-02-01

Respiratory muscle dysfunction, particularly of the diaphragm, may play a key role in the pathophysiological mechanisms that lead to difficulty in weaning patients from mechanical ventilation. The limited mobility of critically ill patients, and of the diaphragm in particular when prolonged mechanical ventilation support is required, promotes the early onset of respiratory muscle dysfunction, but this can also be caused or exacerbated by other factors that are common in these patients, such as sepsis, malnutrition, advanced age, duration and type of ventilation, and use of certain medications, such as steroids and neuromuscular blocking agents. In this review we will study in depth this multicausal origin, in which a common mechanism is altered protein metabolism, according to the findings reported in various models. The understanding of this multicausality produced by the same pathophysiological mechanism could facilitate the management and monitoring of patients undergoing mechanical ventilation.

Diagnosing phaeochromocytoma/paraganglioma in a patient presenting with critical illness: biochemistry versus imaging.

PubMed

Amar, Laurence; Eisenhofer, Graeme

2015-09-01

Phaeochromocytomas and paragangliomas (PPGLs) are revealed by acute cardiovascular complications involving end-organ damage in up to 20% of cases, a presentation associated with particularly high risk for mortality. Among such cases, PPGLs should be considered in patients with unexplained left ventricular failure, multi-organ failure, hypertensive crises or shock. The diagnosis of PPGL commonly relies on measurements of metanephrines in plasma or urine. However, acute critical illness is usually associated with sympathoadrenal activation. Thus, levels of metanephrines in patients in an acute emergency or intensive care setting, whether treated or not with vasoactive drugs, usually cannot be used to reliably diagnose PPGL. Delays in provision of diagnostic test results, particularly when these require 24-h urine collections, may also be incompatible for any need for rapid decisions on patient management or therapeutic interventions. The acute emergency situation therefore represents one exception to the rule where imaging studies to search for a PPGL may be undertaken without biochemical evidence of a catecholamine-producing tumour. © 2015 John Wiley & Sons Ltd.

Parenteral or Enteral Arginine Supplementation Safety and Efficacy.

2016-12-01

Arginine supplementation has the potential to improve the health of patients. Its use in hospitalized patients has been a controversial topic in the nutrition literature, especially concerning supplementation of septic patients. In this article, we review the relevant literature both for and against the use of arginine in critically ill, surgical, and hospitalized patients. The effect of critical illness on arginine metabolism is reviewed, as is its use in septic and critically ill patients. Although mounting evidence supports immunonutrition, there are only a few studies that suggest that this is safe in patients with severe sepsis. The use of arginine has been shown to benefit a variety of critically ill patients. It should be considered for inclusion in combinations of immunonutrients or commercial formulations for groups in whom its benefit has been reported consistently, such as those who have suffered trauma and those in acute surgical settings. The aims of this review are to discuss the role of arginine in health, the controversy surrounding arginine supplementation of septic patients, and the use of arginine in critically ill patients. © 2016 American Society for Nutrition.

Is refeeding syndrome relevant for critically ill patients?

PubMed

Koekkoek, Wilhelmina A C; Van Zanten, Arthur R H

2018-03-01

To summarize recent relevant studies regarding refeeding syndrome (RFS) in critically ill patients and provide recommendations for clinical practice. Recent knowledge regarding epidemiology of refeeding syndrome among critically ill patients, how to identify ICU patients at risk, and strategies to reduce the potential negative impact on outcome are discussed. RFS is a potentially fatal acute metabolic derangement that ultimately can result in marked morbidity and even mortality. These metabolic derangements in ICU patients differ from otherwise healthy patients with RFS, as there is lack of anabolism. This is because of external stressors inducing a hypercatabolic response among other reasons also reflected by persistent high glucagon despite initiation of feeding. Lack of a proper uniform definition complicates diagnosis and research of RFS. However, refeeding hypophosphatemia is commonly encountered during critical illness. The correlations between risk factors proposed by international guidelines and the occurrence of RFS in ICU patients remains unclear. Therefore, regular phosphate monitoring is recommended. Based on recent trials among critically ill patients, only treatment with supplementation of electrolytes and vitamins seems not sufficient. In addition, caloric restriction for several days and gradual increase of caloric intake over days is recommendable.

Role of inhibitory κB kinase and c-Jun NH2-terminal kinase in the development of hepatic insulin resistance in critical illness diabetes.

PubMed

Jiang, Shaoning; Messina, Joseph L

2011-09-01

Hyperglycemia and insulin resistance induced by acute injuries or critical illness are associated with increased mortality and morbidity, as well as later development of type 2 diabetes. The molecular mechanisms underlying the acute onset of insulin resistance following critical illness remain poorly understood. In the present studies, the roles of serine kinases, inhibitory κB kinase (IKK) and c-Jun NH(2)-terminal kinase (JNK), in the acute development of hepatic insulin resistance were investigated. In our animal model of critical illness diabetes, activation of hepatic IKK and JNK was observed as early as 15 min, concomitant with the rapid impairment of hepatic insulin signaling and increased serine phosphorylation of insulin receptor substrate 1. Inhibition of IKKα or IKKβ, or both, by adenovirus vector-mediated expression of dominant-negative IKKα or IKKβ in liver partially restored insulin signaling. Similarly, inhibition of JNK1 kinase by expression of dominant-negative JNK1 also resulted in improved hepatic insulin signaling, indicating that IKK and JNK1 kinases contribute to critical illness-induced insulin resistance in liver.

The care of the critically ill trauma patients is provided by intensivists with various base specialties of training. The purpose of this study was to investigate the impact of intensivists' base specialty of training on the disparity of care process and patient outcome. We performed a retrospective review of an institutional trauma registry at an academic level 1 trauma center. Two intensive care unit teams staffed by either board-certified surgery or anesthesiology intensivists were assigned to manage critically ill trauma patients. Both teams provided care, collaborating with a trauma surgeon in house. We compared patient characteristics, care processes, and outcomes between surgery and anesthesiology groups using Wilcoxon tests or chi-square tests, as appropriate. We identified a total of 620 patients. Patient baseline characteristics including age, sex, transfer status, injury type, injury severity score, and Glasgow coma scale were similar between groups. We found no significant difference in care processes and outcomes between groups. In a logistic regression model, intensivists' base specialty of training was not a significant factor for mortality (odds ratio, 1.46; 95% confidence interval; 0.79-2.80; P = 0.22) and major complication (odds ratio, 1.11; 95% confidence interval, 0.73-1.67; P = 0.63). Intensive care unit teams collaborating with trauma surgeons had minimal disparity of care processes and similar patient outcomes regardless of intensivists' base specialty of training.

Investigate the relationship between psychoactive drugs and delirium. Prospective observational study of 520 critically ill adult patients admitted ≥24h to 6 intensive care units (ICUs). Data were collected on psychoactive drug exposure, use of sedation administration strategies, and incident delirium (Intensive Care Delirium Screening Checklist score≥4). Delirium was detected in 260 (50%) patients, median (IQR) duration 2 (1-5) days, and time to onset 3 (2-5) days. Delirious patients received more low-potency anticholinergic (P<0.0001), antipsychotic (P<0.0001), benzodiazepine (P<0.0001) and non-benzodiazepine sedative (P<0.0001), and opioid (P=0.0008) drugs. Primary regression (24-hours preceding drug exposure) revealed no association between any psychoactive drug and delirium. Post-hoc analysis (extended 48-hour exposure) revealed an association between delirium and high-potency anticholinergic (HR 2.45, 95% CI 1.08-5.54) and benzodiazepine (HR 1.08 per 5mg midazolam-equivalent increment, 95% CI 1.04-1.12) drugs. Delirious patients had longer ICU (P<0.0001) and hospital (P<0.0001) length of stay, and higher ICU and hospital mortality (P=0.003 and P=0.007, respectively). The identification of psychoactive drugs as modifiable delirium risk factors plays an important role in the management of critically ill patients. This is particularly important given the burden of exposure and combinations of drugs used in this vulnerable patient population. Copyright © 2017 Elsevier Inc. All rights reserved.

ABSTRACT Invasive aspergillosis is an important cause of morbidity and mortality among immunocompromised patients. Prolonged neutropenia is the most common risk factor. It has rarely been reported to occur in non-neutropenic critically ill patients in the intensive care unit setting. Mortality rate in this group has been reported to be as high as 92%. We report a case of tracheobronchial aspergillosis in a non-neutropenic critically ill patient to highlight the fact that critically ill patients admitted in the intensive care unit can develop opportunistic infections such as invasive aspergillosis even in the absence of classic risk factors and prior history of immunosuppression. Early diagnosis and prompt initiation of antifungal therapy may improve the outcome and decrease mortality rate. PMID:28634525

Recently published practice guidelines and research reports on pharmacotherapy in critical care patient populations are summarized. The Critical Care Pharmacotherapy Literature Update (CCPLU) Group is composed of over 50 experienced critical care pharmacists who evaluate 31 peer-reviewed journals monthly to identify literature pertaining to pharmacotherapy in critical care populations. Articles are chosen for summarization in a monthly CCPLU Group publication on the basis of applicability and relevance to clinical practice and strength of study design. From January to December 2015, a total of 121 articles were summarized; of these, 3 articles presenting clinical practice guidelines and 12 articles presenting original research findings were objectively selected for inclusion in this review based on their potential to change or reinforce current evidence-based practice. The reviewed guidelines address the management of intracranial hemorrhage (ICH), adult advanced cardiac life support (ACLS) and post-cardiac arrest care, and the management of supraventricular tachycardia (SVT). The reviewed research reports address topics such as nutrition in critically ill adults, administration of β-lactams for severe sepsis, anticoagulant selection in the context of continuous renal replacement therapy, early goal-directed therapy in septic shock, magnesium use for neuroprotection in acute stroke, and progesterone use in patients with traumatic brain injury. Important recent additions to the critical care pharmacy literature include updated joint clinical practice guidelines on the management of spontaneous ICH, ACLS, and SVT.

Managing crisis: the role of primary care for people with serious mental illness.

PubMed

Lester, Helen; Tritter, Jonathan Q; Sorohan, Helen

2004-01-01

More than 30% of patients with serious mental illness in the United Kingdom now receive all their health care solely from primary care. This study explored the process of managing acute mental health crises from the dual perspective of patients and primary care health professionals. Eighteen focus groups involving 45 patients, 39 general practitioners, and eight practice nurses were held between May and November 2002 in six Primary Care Trusts across the British West Midlands. The topic guide explored perceptions of gold standard care, current issues and critical incidents in receiving/providing care, and ideas on improving services. Themes relevant to the management of acute crisis included issues of process, such as access, advocacy, communication, continuity, and coordination of care; the development of more structured care that might reduce the need for crisis responses; and issues raised by the development of a more structured approach to care. Access to services is a complicated yet crucial feature of managing care in a crisis, with patients identifying barriers at the level of primary care and health professionals at the interface with secondary care. The development of more structured systems as a solution may generate its own ethical and pragmatic challenges.

Cardiac disease is the leading cause of death in Lebanon, accounting for 22% to 26% of total deaths in the country. A thorough understanding of perceptions of cardiac illness and related self-care management is critical to the development of secondary prevention programs that are specific to the Lebanese culture. To explore the cultural perceptions of cardiac illness and the associated meaning of self-care among Lebanese patients. Using a qualitative descriptive method, semistructured interviews were conducted with a purposive sample of 15 Lebanese cardiac patients recruited from a medical center in Beirut, Lebanon. The qualitative descriptive analysis yielded one overarching and two other themes describing perceptions of cardiac illness and self-care within the Lebanese cultural context. The overarching cultural theme was, "Lebanese cardiac patients were unfamiliar with the term concept and meaning of self-care." Lebanese cardiac patients thanked God and accepted their fate (Theme I). The participants considered their cardiac incident a life or death warning (Theme II). Health care providers need to consider patients' cultural perception of illness while planning and evaluating cardiac self-care programs. © The Author(s) 2015.

Glutamine has been launched as a conditionally indispensible amino acid for the critically ill. Supplementation has been recommended in guidelines from international societies. Although data have been presented pointing out that glutamine supplementation may not be for everybody, recommendations for treatments and design of study protocols have included all critically ill patients. Results from more recent studies and meta-analyses indicate that indiscriminate use of glutamine supplementation in critically ill patients may actually cause harm rather than beneficial effects. This viewpoint sorts out arguments of controversy in the glutamine story.

Mortality in pediatric cardiovascular failure is markedly improved with the advent of neonatal and pediatric intensive care and with the implementation of treatment guidelines. In 2002 the American College of Critical Care Medicine Clinical Practice Parameters for Hemodynamic Support of Pediatric and Neonatal Shock reported mortality rates of 0%-5% in previously healthy and 10% in chronically ill children with septic shock associated with implementation of "best clinical practices". Early recognition of shock is the key to successful resuscitation in critically ill children. Often, shock results in or co-exists with myo-cardial dysfunction or acute lung injury. Recognition and appropriate management of these insults is crucial for successful outcomes. Resuscitation should be directed to restoration of tissue perfusion and normalization of cardiac and respiratory function. The underlying cause of shock should also be addressed urgently. The physiological response of individual children to shock resuscitation varies and is often unpredictable. Therefore, repeated assessments of vital parameters are needed for taking appropriate decisions. Global indices of tissue oxygen delivery help in targeting therapies more accurately. Isotonic fluids form the cornerstone of treatment and the amount required for resuscitation is based on etiologies and therapeutic response. After resuscitation has been initiated, targeted history and clinical evaluation must be performed to ascertain the cause of shock and management of co-morbidities should be implemented simultaneously. While the management of shock can be protocol based, the treatment needs to be individualized depending on the suspected etiology and therapeutic response particularly for children who suffer from congenital heart disease.

Long-term psychosocial impact reported by childhood critical illness survivors: a systematic review

2014-01-01

Aim To undertake a qualitative systematic review that explores psychological and social impact, reported directly from children and adolescents at least 6 months after their critical illness. Background Significant advances in critical care have reduced mortality from childhood critical illness, with the majority of patients being discharged alive. However, it is widely reported that surviving critical illness can be traumatic for both children and their family. Despite a growing body of literature in this field, the psychological and social impact of life threatening critical illness on child and adolescent survivors, more than 6 months post event, remains under-reported. Data sources Searches of six online databases were conducted up to February 2012. Review methods Predetermined criteria were used to select studies. Methodological quality was assessed using a standardized checklist. An adapted version of the thematic synthesis approach was applied to extract, code and synthesize data. Findings Three studies met the inclusion criteria, which were all of moderate methodological quality. Initial coding and synthesis of data resulted in five descriptive themes: confusion and uncertainty, other people's narratives, focus on former self and normality, social isolation and loss of identity, and transition and transformation. Further synthesis culminated in three analytical themes that conceptualize the childhood survivors' psychological and social journey following critical illness. Conclusions Critical illness in childhood can expose survivors to a complex trajectory of recovery, with enduring psychosocial adversity manifesting in the long term. Nurses and other health professionals must be aware and support the potential multifaceted psychosocial needs that may arise. Parents and families are identified as fundamental in shaping psychological and social well-being of survivors. Therefore intensive care nurses must take opportunities to raise parents' awareness of the journey of survival and provide appropriate support. Further empirical research is warranted to explore the deficits identified with the existing literature. PMID:24147805

Approach to critical illness polyneuropathy and myopathy.

PubMed

Pati, S; Goodfellow, J A; Iyadurai, S; Hilton-Jones, D

2008-07-01

A newly acquired neuromuscular cause of weakness has been found in 25-85% of critically ill patients. Three distinct entities have been identified: (1) critical illness polyneuropathy (CIP); (2) acute myopathy of intensive care (itself with three subtypes); and (3) a syndrome with features of both 1 and 2 (called critical illness myopathy and/or neuropathy or CRIMYNE). CIP is primarily a distal axonopathy involving both sensory and motor nerves. Electroneurography and electromyography (ENG-EMG) is the gold standard for diagnosis. CIM is a proximal as well as distal muscle weakness affecting both types of muscle fibres. It is associated with high use of non-depolarising muscle blockers and corticosteroids. Avoidance of systemic inflammatory response syndrome (SIRS) is the most effective way to reduce the likelihood of developing CIP or CIM. Outcome is variable and depends largely on the underlying illness. Detailed history, careful physical examination, review of medication chart and analysis of initial investigations provides invaluable clues towards the diagnosis.

Feeding the critically ill obese patient: a systematic review protocol.

PubMed

Secombe, Paul; Harley, Simon; Chapman, Marianne; Aromataris, Edoardo

2015-10-01

The objective of this review is to identify effective enteral nutritional regimens targeting protein and calorie delivery for the critically ill obese patient on morbidity and mortality.More specifically, the review question is:In the critically ill obese patient, what is the optimal enteral protein and calorie target that improves mortality and morbidity? The World Health Organization (WHO) defines obesity as abnormal or excessive fat accumulation that may impair health, or, empirically, as a body mass index (BMI) ≥ 30 kg/m. Twenty-eight percent of the Australian population is obese with the prevalence rising to 44% in rural areas, and there is evidence that rates of obesity are increasing. The prevalence of obese patients in intensive care largely mirrors that of the general population. There is concern, however, that this may also be rising. A recently published multi-center nutritional study of critically ill patients reported a mean BMI of 29 in their sample, suggesting that just under 50% of their intensive care population is obese. It is inevitable, therefore, that the intensivist will care for the critically ill obese patient.Managing the critically ill obese patient is challenging, not least due to the co-morbid diseases frequently associated with obesity, including diabetes mellitus, cardiovascular disease, dyslipidaemia, sleep disordered breathing and respiratory insufficiency, hepatic steatohepatitis, chronic kidney disease and hypertension. There is also evidence that metabolic processes differ in the obese patient, particularly those with underlying insulin resistance, itself a marker of the metabolic syndrome, which may predispose to futile cycling, altered fuel utilization and protein catabolism. These issues are compounded by altered drug pharmacokinetics, and the additional logistical issues associated with prophylactic, therapeutic and diagnostic interventions.It is entirely plausible that the altered metabolic processes observed in the obese intensify and compound the metabolic changes that occur during critical illness. The early phases of critical illness are characterized by an increase in energy expenditure, resulting in a catabolic state driven by the stress response. Activation of the stress response involves up-regulation of the sympathetic nervous system and the release of pituitary hormones resulting in altered cortisol metabolism and elevated levels of endogenous catecholamines. These produce a range of metabolic disturbances including stress hyperglycemia, arising from both peripheral resistance to the effects of anabolic factors (predominantly insulin) and increased hepatic gluconeogenesis. Proteolysis is accelerated, releasing amino acids that are thought to be important in supporting tissue repair, immune defense and the synthesis of acute phase reactants. There is also altered mobilization of fuel stores, futile cycling, and evidence of altered lipoprotein metabolism. In the short term this is likely to be an adaptive response, but with time and ongoing inflammation this becomes maladaptive with a concomitant risk of protein-calorie malnutrition, immunosuppression and wasting of functional muscle tissue resulting from protein catabolism, and this is further compounded by disuse atrophy. Muscle atrophy and intensive care unit (ICU) acquired weakness is complex and poorly understood, but it is postulated that the provision of calories and sufficient protein to avoid a negative nitrogen balance mitigates this process. Avoiding lean muscle mass loss in the obese intuitively has substantial implications, given the larger mass that is required to be mobilized during their rehabilitation phase.There is, in addition, evolving evidence that hormones derived from both the gut and adipose tissue are also involved in the response to stress and critical illness, and that adipose tissue in particular is not a benign tissue bed, but rather should be considered an endocrine organ. Some of these hormones are thought to be pro-inflammatory and some anti-inflammatory; however both the net result and clinical significance of these are yet to be fully elucidated.The provision of adequate nutrition has become an integral component of supportive ICU care, but is complex. There is ongoing debate within critical care literature regarding the optimal route of delivery, the target dose, and the macronutrient components (proportion of protein and non-protein calories) of nutritional support. A number of studies have associated caloric deficit with morbidity and mortality, with the resultant assumption that prescribing sufficient calories to match energy expenditure will reduce morbidity and mortality, although the evidence base underpinning this assumption is limited to observational studies and small, randomized trials.There is research available that suggests hyper-caloric feeding or hyper-alimentation, particularly of carbohydrates, may result in increased morbidity including hyperglycemia, liver steatosis, respiratory insufficiency with prolonged duration of mechanical ventilation, re-feeding syndrome and immune suppression. But the results from studies of hypo-caloric and eucaloric feeding regimens in critically ill patients are conflicting, independent of the added metabolic complexities observed in the critically ill obese patient.Notwithstanding the debate regarding the dose and components of nutritional therapy, there is consensus that nutrition should be provided, preferably via the enteral route, and preferably initiated early in the ICU admission. The enteral route is preferred for a variety of reasons, not the least of which is cost. In addition there is evidence to suggest the enteral route is associated with the maintenance of gut integrity, a reduction in bacterial translocation and infection rates, a reduction in the incidence of stress ulceration, attenuation of oxidative stress, release of incretins and other entero-hormones, and modulation of systemic immune responses. Yet there is evidence that the initiation of enteral nutritional support for the obese critically ill patient is delayed, and that when delivered is at sub-optimal levels. The reasons for this remain obscure, but may be associated with the false assumption that every obese patient has nutritional reserves due to their adipose tissues, and can therefore withstand longer periods with no, or reduced nutritional support. In fact obesity does not necessarily protect from malnutrition, particularly protein and micronutrient malnutrition. It has been suggested by some authors that the malnutrition status of critically ill patients is a stronger predictor of mortality than BMI, and that once malnutrition status is controlled for, the apparent protective effects of obesity observed in several epidemiological studies dissipate. This would be consistent with the large body of evidence that associates malnutrition (BMI < 20 kg/m) with increased mortality, and has led some authors to postulate that the weight-mortality relationship is U-shaped. This has proven difficult to demonstrate, however, due to recognized confounding influences such as chronic co-morbidities, baseline nutritional status and the nature of the presenting critical illness.This has led to interest in nutritional regimens targeting alternative calorie and protein goals to protect the obese critically ill patient from complications arising from critical illness, and particularly protein catabolism. However, of the three major nutritional organizations, the American Society of Parenteral and Enteral Nutrition (ASPEN) is the only professional organization to make specific recommendations about providing enteral nutritional support to the critically ill obese patient, recommending a regimen targeting a hypo-caloric, high-protein goal. It is thought that this regimen, in which 60-70% of caloric requirements are provided promotes steady weight loss, while providing sufficient protein to achieve a neutral, or slightly positive, nitrogen balance, mitigating lean muscle mass loss, and allowing for wound healing. Targeting weight loss is proposed to improve insulin sensitivity, improve nursing care and reduce the risk of co-morbidities, although how this occurs and whether it can occur over the relatively short time frame of an intensive care admission (days to weeks) remains unclear. Despite these recommendations observational data of international nutritional practice suggest that ICU patients are fed uniformly low levels of calories and protein across BMI groups.Supporting the critically ill obese patient will become an increasingly important skill in the intensivist's armamentarium, and enteral nutritional therapy forms a cornerstone of this support. Yet, neither the optimal total caloric goal nor the macronutrient components of a feeding regimen for the critically ill obese patient is evident. Although the suggestion that altering the macronutrient goals for this vulnerable group of patients appears to have a sound physiological basis, the level of evidence supporting this remains unclear, and there are no systematic reviews on this topic. The aim of this systematic review is to evaluate existing literature to determine the best available evidence describing a nutritional strategy that targets energy and protein delivery to reduce morbidity and mortality for the obese patient who is critically ill.

To determine the implementation of National Institute for Health and Care Excellence guidance (NICE CG83) for posthospital discharge critical illness follow-up and rehabilitation programmes. Closed-question postal survey. Adult intensive care units (ICUs) across the UK, identified from national databases of organisations. Specialist-only and private ICUs were not included. Senior respiratory critical care physiotherapy clinicians. A representative sample of 182 surveys was returned from the 240 distributed (75.8% (95% CI 70.4 to 81.2)). Only 48 organisations (27.3% (95% CI 20.7 to 33.9)) offered a follow-up service 2-3 months following hospital discharge, the majority (n=39, 84.8%) in clinic format. 12 organisations reported posthospital discharge rehabilitation programmes (6.8% (95% CI 3.1 to 10.5)), albeit only 10 of these operated on a regular basis. Lack of funding was reported as the most frequent (n=149/164, 90%) and main barrier (n=99/156, 63.5%) to providing services. Insufficient resources (n=71/164, 43.3%) and lack of priority by the clinical management team (n=66/164, 40.2%) were also highly cited barriers to service delivery. NICE CG83 has been successful in profiling the importance of rehabilitation for survivors of critical illness. However, 4 years following publication of CG83 there has been limited development of this clinical service across the UK. Strategies to support delivery of such quality improvement programmes are urgently required to enhance patient care. Published by the BMJ Publishing Group Limited.

Adequate and timely provision of nutritional support is a crucial component of care of the critically ill burn patient. The goal of this study was to assess a single center's consistency with Society of Critical Care Medicine/American Society for Parenteral and Enteral Nutrition (SCCM/ASPEN) guidelines for nutritional support in critically ill patients. Acutely burned patients >45kg in weight admitted to a regional burn center during a two-year period and who required 5 or more days of full enteral nutritional support were eligible for inclusion in this retrospective review. Specific outcomes evaluated include time from admission to feeding tube placement and enteral feeding initiation and percent of nutritional goal received within the first week of hospital stay. Descriptive statistics were used for all analyses. IRB approval was obtained. Thirty-seven patients were included in this retrospective review. Median age of patients was 44.9 years (IQR: 24.2-55.1), and median burn injury size was 30% (IQR: 19-47). Median time to feeding tube placement was 31.1h post admission (IQR: 23.6-50.2h), while median time to initiation of EN was 47.9h post admission (IQR: 32.4-59.9h). The median time required for patients to reach 60% of caloric goal was 3 days post-admission (IQR: 3-4.5). The median time for initiation of enteral nutrition was within the SCCM/ASPEN guidelines for initial nutrition in the critically ill patient. This project identified a 16h time lag between placement of enteral access and initiation of enteral nutrition. Development of a protocol for feeding tube placement and enteral nutrition management may optimize early nutritional support in the acutely injured burn patient.

To determine the feasibility and describe the process of implementing a pediatric critical care bedside ultrasound program in a large academic PICU and to evaluate the impact of bedside ultrasound on clinical management. Retrospective case series, description of program implementation. Single-center quaternary noncardiac PICU in a children's hospital. Consecutive patients from January 22, 2012, to July 22, 2012, with bedside ultrasounds performed and interpreted by pediatric critical care practitioners. A pediatric critical care bedside ultrasound program consisting of a 2-day immersive course followed by clinical performance with internal quality assurance review was implemented. Studies performed in the PICU following training were documented and reviewed against reference standards including subspecialist-performed ultrasound or clinical response. Seventeen critical care faculties and eight fellows recorded 201 bedside ultrasound studies over 6 months in defined core applications: 57 procedural (28%), 76 hemodynamic (38%), 35 thoracic (17%), and 33 abdominal (16%). A quality assurance review identified 23 studies (16% of all nonprocedural studies) as critical (affected clinical management or gave valuable information). Forty-eight percent of those studies (11/23) were within the hemodynamic core. The proportion of critical studies were not significantly different across the applications (hemodynamic, 11/76 [15%] vs thoracic and abdominal, 12/68 [18%]; p = 0.65). Examples of critical studies include evidence of tamponade secondary to pleural effusions, identification of pulmonary hypertension, hemodynamic assessment before tracheal intubation, recognition of hypovolemia and systemic vascular resistance abnormalities, determination of pneumothorax, location of chest tube and urinary catheter, and differentiation of pleural fluid from pulmonary consolidation. Implementation of a critical care bedside ultrasound program for critical care providers in a large academic PICU is feasible. Bedside ultrasound evaluation and interpretation by intensivists affected the management of critically ill children.

The development of right heart catheterization has provided the clinician the ability to diagnose patients with congenital and acquired right heart disease, and to monitor patients in the ICU with significant cardiovascular illnesses. The development of bedside pulmonary artery catheterization has become a standard of care for the critically ill patient since its introduction into the ICU almost 40 years ago. However, adoption of this procedure into the mainstream of clinical practice occurred without prior evaluation or demonstration of its clinical or cost-effectiveness. Moreover, current randomized, controlled trials provide little evidence in support of the clinical utility of pulmonary artery catheterization in the management of critically ill patients. Nevertheless, the right heart catheter is an important diagnostic tool to assist the clinician in the diagnosis of congenital heart disease and acquired right heart disease, and moreover, when catheter placement is proximal to the right auricle (atria), this catheter provides an important and safe route for administration of fluids, medications, and parenteral nutrition. The purpose of this manuscript is to review the development of right heart catheterization that led to the ability to conduct physiologic studies in cardiovascular dynamics in normal individuals and in patients with cardiovascular diseases, and to review current controversies of the extension of the right heart catheter, the pulmonary artery catheter.

2016-09-01

Obesity is a leading cause of preventable death worldwide. The prevalence of obesity has been increasing and is associated with an increased risk for other co-morbidities. In the critical care setting, nearly one third of patients are obese. Obese critically ill patients pose significant physical and on-physical challenges to providers, including optimization of nutrition therapy. Intuitively, obese patients would have worse critical care-related outcome. On the contrary, emerging data suggests that critically ill obese patients have improved outcomes, and this phenomenon has been coined "the obesity paradox." The purposes of this review will be to outline the historical views and pathophysiology of obesity and epidemiology of obesity, describe the challenges associated with obesity in the intensive care unit setting, review critical care outcomes in the obese, define the obesity-critical care paradox, and identify the challenges and role of nutrition support in the critically ill obese patient.

Critical care physicians recognise persistent critical illness as a specific syndrome, yet few data exist for the timing of the transition from acute to persistent critical illness. Defining the onset of persistent critical illness as the time at which diagnosis and illness severity at intensive care unit (ICU) arrival no longer predict outcome better than do simple pre-ICU patient characteristics, we measured the timing of this onset at a population level in Australia and New Zealand, and the variation therein, and assessed the characteristics, burden of care, and hospital outcomes of patients with persistent critical illness. In this retrospective, population-based, observational study, we used data for ICU admission in Australia and New Zealand from the Australian and New Zealand Intensive Care Society Adult Patient Database. We included all patients older than 16 years of age admitted to a participating ICU. We excluded patients transferred from another hospital and those admitted to an ICU for palliative care or awaiting organ donation. The primary outcome was in-hospital mortality. Using statistical methods in evenly split development and validation samples for risk score development, we examined the ability of characteristics to predict in-hospital mortality. Between Jan, 2000, and Dec, 2014, we studied 1 028 235 critically ill patients from 182 ICUs across Australia and New Zealand. Among patients still in an ICU, admission diagnosis and physiological derangements, which accurately predicted outcome on admission (area under the receiver operating characteristics curve 0·898 [95% CI 0·897-0·899] in the validation cohort), progressively lost their predictive ability and no longer predicted outcome more accurately than did simple antecedent patient characteristics (eg, age, sex, or chronic health status) after 10 days in the ICU, thus empirically defining the onset of persistent critical illness. This transition occurred between day 7 and day 22 across diagnosis-based subgroups and between day 6 and day 15 across risk-of-death-based subgroups. Cases of persistent critical illness accounted for only 51 509 (5·0%) of the 1 028 235 patients admitted to an ICU, but for 1 029 345 (32·8%) of 3 138 432 ICU bed-days and 2 197 108 (14·7%) of 14 961 693 hospital bed-days. Overall, 12 625 (24·5%) of 51 509 patients with persistent critical illness died and only 23 968 (46·5%) of 51 509 were discharged home. Onset of persistent critical illness can be empirically measured at a population level. Patients with this condition consume vast resources, have high mortality, have much less chance of returning home than do typical ICU patients, and require dedicated future research. ICU clinicians should be aware that the risk of in-hospital mortality can change quickly over the first 2 weeks of an ICU course and be sure to incorporate such changes in their decision making and prognostication.

Moore, Sarah; Weiss, Brian; Pascual, Jose L; Kaplan, Lewis J

Sepsis and septic shock are each commonly accompanied by acute respiratory failure and the need for invasive as well as non-invasive ventilation throughout a patient's intensive care unit course. We explore the underpinnings of acute respiratory failure of pulmonary as well as non-pulmonary origin in the context of invasive and non-invasive management approaches. Both pharmacologic and non-pharmacologic adjuncts to ventilatory and oxygenation support are highlighted as well. Finally, rescue modalities are positioned within the intensivist's armamentarium for global care of support of the critically ill or injured patient with sepsis or septic shock.

Understanding consumer initiation of shared decision making (SDM) is critical to improving SDM in mental health consultations, particularly because providers do not always invite consumer participation in treatment decisions. This study examined the association between consumer initiation of nine elements of SDM as measured by the SDM scale, and measures of consumer illness self-management and the consumer-provider relationship. In 63 mental health visits, three SDM elements were associated with self-management or relationship factors: discussion of consumer goals, treatment alternatives, and pros and cons of a decision. Limitations, implications, and future directions are discussed.

Although fever and hypothermia are common abnormal physical signs observed in patients admitted to intensive care units (ICU), little data exist on their optimal management. The objective of this study was to describe contemporary practices and determinants of management of temperature abnormalities among patients admitted to ICUs. Site leaders of the multi-national EUROBACT study were surveyed regarding diagnosis and management of temperature abnormalities among patients admitted to their ICUs. Of the 162 ICUs originally included in EUROBACT, responses were received from 139 (86%) centers in 23 countries in Europe (117), South America (8), Asia (5), North America (4), Australia (3) and Africa (2). A total of 117 (84%) respondents reported use of a specific temperature threshold in their ICU to define fever. A total of 14 different discrete levels were reported with a median of 38.2°C (inter-quartile range, IQR, 38.0°C to 38.5°C). The use of thermometers was protocolized in 91 (65%) ICUs and a wide range of methods were reportedly used, with axillary, tympanic and urinary bladder sites as the most common as primary modalities. Only 31 (22%) of respondents indicated that there was a formal written protocol for temperature control among febrile patients in their ICUs. In most or all cases practice was to control temperature, to use acetaminophen, and to perform a full septic workup in febrile patients and that this was usually directed by physician order. While reported practice was to treat nearly all patients with neurological impairment and most patients with acute coronary syndromes and infections, severe sepsis and septic shock, this was not the case for most patients with liver failure and fever. A wide range of definitions and management practices were reported regarding temperature abnormalities in the critically ill. Documenting temperature abnormality management practices, including variability in clinical care, is important to inform planning of future studies designed to optimize infection and temperature management strategies in the critically ill.

Haemato-oncology patients often require critical care support due to side-effects of treatment. Discharge can mark the start of an uncertain journey due to the impact of critical illness on health-related quality of life. Qualitatively establishing needs is a priority as current evidence is limited. To qualitatively explore perceptions of haemato-oncology patients' health-related quality of life after critical illness and explore how healthcare professionals can provide long-term support. Nine in-depth interviews were conducted three to eighteen months post-discharge from critical care. Phenomenology was used to gain deeper understanding of the patients' lived experience. A 19-bedded Intensive Care Unit in a specialist cancer centre. Five major themes emerged: Intensive care as a means to an end; Rollercoaster of illness; Reliance on hospital; Having a realistic/sanguine approach; Living in the moment. Haemato-oncology patients who experience critical illness may view it as a small part of a larger treatment pathway, thus health-related quality of life is impacted by this rather than the acute episode. Discharge from the intensive care unit can be seen as a positive end-point, allowing personal growth in areas such as relationships and living life to the full. The contribution of health-care professionals and support of significant others is regarded as critical to the recovery experience. Copyright © 2017 Elsevier Ltd. All rights reserved.

Pain, a persistent problem in critically ill patients, adversely affects outcomes. Despite recommendations, no evidence-based nonpharmacological approaches for pain treatment in critically ill patients have been developed. To investigate the effects of a multimodal integrative intervention on the incidence of pain and on secondary outcomes: intensity of pain, hemodynamic indices (systolic and mean arterial pressure, heart rate), anxiety, fear, relaxation, optimism, and sleep quality. A randomized, controlled, double-blinded repeated-measures trial with predetermined eligibility criteria was conducted. The intervention included relaxation, guided imagery, moderate pressure massage, and listening to music. The primary outcome was incidence of pain (score on Critical Care Pain Observation Tool > 2). Other outcomes included pain ratings, hemodynamic measurements, self-reported psychological outcomes, and quality of sleep. Repeated-measures models with adjustments (baseline levels, confounders) were used. Among the 60 randomized critically ill adults in the sample, the intervention group experienced significant decreases in the incidence ( P = .003) and ratings of pain ( P < .001). Adjusted models revealed a significant trend for lower incidence ( P = .002) and ratings ( P < .001) of pain, systolic arterial pressure ( P < .001), anxiety ( P = .01), and improved quality of sleep ( P = .02). A multimodal integrative intervention may be effective in decreasing pain and improving pain-related outcomes in critically ill patients. © 2018 American Association of Critical-Care Nurses.

Critical illness has profound effects on muscle strength and long-term physical morbidity. However, there remains a paucity of evidence for the aetiology of critical illness related weakness. Recent animal model research identified that hypercapnia may reduce the rate of muscle loss. The aim of this study was to determine the effect of hypercapnia on respiratory and peripheral skeletal muscle in patients with critical illness. A pilot observational study of mechanically ventilated critically ill patients at a tertiary critical care unit who were retrospectively categorised as: 1) Respiratory failure with normocapnia; 2) Respiratory failure with hypercapnia; and 3) brain injury. Diaphragm thickness and quadriceps rectus femoris cross-sectional area (RFCSA) were measured using ultrasound imaging at baseline and at days 3, 5, 7 and 10 of mechanical ventilation. Significant reductions in RFCSA muscle loss were observed for all time-points when compared to baseline [day 10: -14.9%±8.2 p< 0.001], and in diaphragm thickness between baseline and day 7 [day 7: -5.8%±9.5 p=0.029). No correlation was identified between the rate of muscle mass loss in the diaphragm and RFCSA. In this pilot study, peripheral skeletal muscle weakness occurred early and rapidly within the critical care population, irrespective of carbon dioxide levels. Copyright © 2018 Elsevier Inc.

The Gut as the Motor of Multiple Organ Dysfunction in Critical Illness

PubMed Central

Klingensmith, Nathan J.; Coopersmith, Craig M.

2015-01-01

Synopsis All elements of the gut – the epithelium, the immune system, and the microbiome – are impacted by critical illness and can, in turn, propagate a pathologic host response leading to multiple organ dysfunction syndrome. Preclinical studies have demonstrated that this can occur by release of toxic gut-derived substances into the mesenteric lymph where they can cause distant damage. Further, intestinal integrity is compromised in critical illness with increases in apoptosis and permeability. There is also increasing recognition that microbes alter their behavior and can become virulent based upon host environmental cues. Gut failure is common in critically ill patients; however, therapeutics targeting the gut have proven to be challenging to implement at the bedside. Numerous strategies to manipulate the microbiome have recently been used with varying success in the ICU. PMID:27016162

 We sought feedback from elderly patients living with asthma to understand their experience with assuming self-management roles for their asthma in order to inform the design and implementation of a primary care-based strategy that could best support their asthma control. We held six focus groups with a total of 31 English- and Spanish-speaking older adults with a current diagnosis of asthma. Focus groups addressed the effect of asthma on patients' lives and self-management strategies. Transcripts were analyzed using constant comparative techniques. Asthma exerted a consistent effect on patients' physical and psychological well-being. Common barriers to self-care included misuse of controller medications and uncertainty whether shortness of breath, fatigue, and cough were due to their asthma or some other chronic illness. Patients developed coping strategies to continue with daily activities even when experiencing symptoms, but did not recognize attainable asthma quality of life. Asthma had a distinct impact on elderly adults' quality of life; due to their longstanding history with this condition, many patients had accepted these symptoms as a "new normal." Developing strategies to reorient patients' perceptions of the possibilities for managing their illness will be critical to the success of asthma self-management support programs specific to older adults.

Pediatric solid organ transplant recipients are medically fragile and present with complex care issues requiring high-level management at home. Parents of hospitalized children have reported inadequate preparation for discharge, resulting in problems transitioning from hospital to home and independently self-managing their child’s complex care needs. The aim of this study was to investigate factors associated with the transition from hospital to home and chronic illness care for parents of heart, kidney, liver, lung, or multivisceral recipients. Fifty-one parents from five pediatric transplant centers completed questionnaires on the day of hospital discharge and telephone interviews at 3-week, 3-month, and 6-months following discharge from the hospital. Care coordination (p = .02) and quality of discharge teaching (p < .01) was significantly associated with parent readiness for discharge. Readiness for hospital discharge was subsequently significantly associated with post-discharge coping difficulty (p = .02) at 3-weeks, adherence with medication administration (p = .03) at 3-months, and post-discharge coping difficulty (p = .04) and family management (p = .02) at 6-months post-discharge. The results underscore the important aspect of education and care coordination in preparing patients and families to successfully self-manage after hospital discharge. Assessing parental readiness for hospital discharge is another critical component for identifying risk of difficulties in managing post-discharge care. PMID:25425201

The role of nutritional support in the physical and functional recovery of critically ill patients: a narrative review.

2017-08-26

The lack of benefit from randomised controlled trials has resulted in significant controversy regarding the role of nutrition during critical illness in terms of long-term recovery and outcome. Although methodological caveats with a failure to adequately appreciate biological mechanisms may explain these disappointing results, it must be acknowledged that nutritional support during early critical illness, when considered alone, may have limited long-term functional impact.This narrative review focuses specifically on recent clinical trials and evaluates the impact of nutrition during critical illness on long-term physical and functional recovery.Specific focus on the trial design and methodological limitations has been considered in detail. Limitations include delivery of caloric and protein targets, patient heterogeneity, short duration of intervention, inappropriate clinical outcomes and a disregard for baseline nutritional status and nutritional intake in the post-ICU period.With survivorship at the forefront of critical care research, it is imperative that nutrition studies carefully consider biological mechanisms and trial design because these factors can strongly influence outcomes, in particular long-term physical and functional outcome. Failure to do so may lead to inconclusive clinical trials and consequent rejection of the potentially beneficial effects of nutrition interventions during critical illness.

Adequate caloric intake plays a vital role in the course of illness and the recovery of critically ill patients. Nutritional status and nutrient delivery during critical illness have been linked to clinical outcomes such as mortality, incidence of infection, and length of stay. However, feeding practices with critically ill pediatric patients after cardiac surgery are variable. The Pediatric Cardiac Intensive Care Society sought to provide an expert review on provision of nutrition to pediatric cardiac intensive care patients, including caloric requirements, practical considerations for providing nutrition, safety of enteral nutrition in controversial populations, feeding considerations with chylothorax, and the benefits of feeding beyond nutrition. This article addresses these areas of concern and controversy.

[Enteral nutrition and the critically ill patient].

1999-09-01

Critically ill patients often suffer from malnutrition y loss of muscle weight throughout the whole time they are ill, even when they receive nutritional therapy, due to the tremendous amount of stress they undergo accompanied by a high degree of hypercatabolism. The most recent theories all coincide in the importance of the intestine as the preferred way for nutrients to enter the bodies of these patients because besides fulfilling its function to absorb and digest nutrients, the intestine plays an important role as a barrier to bacteria and their toxins. For these reasons, enteral nutrition should be the first option to consider whenever we must feed a critically ill patient by artificial means.

The Relationship Between Health Management and Information Behavior Over Time: A Study of the Illness Journeys of People Living With Fibromyalgia.

Chen, Annie T

2016-10-25

Over the course of a chronic illness, patients face many challenges, including understanding what is happening to them and developing an effective strategy for managing illness. While there is existing literature concerning how people seek health-related information and cope with chronic illnesses, there is a need for additional research on how information affects patients' understandings of their illness, and how changes in this understanding affect their health management strategies over time. This study examined how health management, information seeking, and information consumption and use processes are related throughout an illness. A diversified recruitment strategy involving multiple media channels was used to recruit participants for an interview study. During the interviews, participants were asked to draw an "illness journey" timeline. The data were analyzed using a qualitative approach drawn from Interpretative Phenomenological Analysis and Grounded Theory. The study identified four main health management features of illness journeys: onset, progression toward diagnosis, acceptance, and development of an effective management strategy. The study then focused on how information seeking changes over illness journeys, particularly in terms of a transition from active information seeking to monitoring with intermittent focused searching. Last, the paper describes the information consumption and use processes that patients engaged in throughout their journey. This study makes three important contributions to the field. First, it presents an integrated conceptualization of how health management and information behaviors are related on illness journeys. Second, it adds to our existing knowledge on health literacy and self-management of chronic illness. Third, the study has implications for health interface design.

Critically ill patients develop severe stress, inflammation and a clinical state that may raise the utilization and metabolic replacement of many nutrients and especially zinc, depleting their body reserves. This study was designed to assess the zinc status in critical care patients with systemic inflammatory response syndrome (SIRS), comparing them with a group of healthy people, and studying the association with expression of zinc transporters. This investigation was a prospective, multicentre, comparative, observational and analytic study. Twelve critically ill patients from different hospitals and 12 healthy subjects from Granada, Spain, all with informed consent were recruited. Data on daily nutritional assessment, ICU severity scores, inflammation, clinical and nutritional parameters, plasma and blood cell zinc concentrations, and levels of transcripts for zinc transporters in whole blood were taken at admission and at the seventh day of the ICU stay. Zinc levels on critical ill patient are diminish comparing with the healthy control (HS: 0.94 ± 0.19; CIPF: 0.67 ± 0.16 mg/dL). The 58% of critical ill patients showed zinc plasma deficiency at beginning of study while 50.0% of critical ill after 7 days of ICU stay. ZnT7, ZIP4 and ZIP9 were the zinc transporters with highest expression in whole blood. In general, all zinc transporters were significantly down-regulated (P < 0.05) in the critical ill population at admission in comparison with healthy subjects. Severity scores and inflammation were significantly associated (P < 0.05) with zinc plasma levels, and zinc transporters ZIP3, ZIP4, ZIP8, ZnT6, ZnT7. Expression of 11 out of 24 zinc transporters was analysed, and ZnT1, ZnT4, ZnT5 and ZIP4, which were downregulated by more than 3-fold in whole blood of patients. In summary, in our study an alteration of zinc status was related with the severity-of-illness scores and inflammation in critical ill patients since admission in ICU stay. SIRS caused a general shut-down of expression of zinc transporters in whole blood. That behavior was associated with severity and inflammation of patients at ICU admission regardless zinc status. We conclude that zinc transporters in blood might be useful indicators of severity of systemic inflammation and outcome for critically ill patients. Copyright © 2017 Elsevier GmbH.

Optimizing point-of-care testing in clinical systems management.

Kost, G J

1998-01-01

The goal of improving medical and economic outcomes calls for leadership based on fundamental principles. The manager of clinical systems works collaboratively within the acute care center to optimize point-of-care testing through systematic approaches such as integrative strategies, algorithms, and performance maps. These approaches are effective and efficacious for critically ill patients. Optimizing point-of-care testing throughout the entire health-care system is inherently more difficult. There is potential to achieve high-quality testing, integrated disease management, and equitable health-care delivery. Despite rapid change and economic uncertainty, a macro-strategic, information-integrated, feedback-systems, outcomes-oriented approach is timely, challenging, effective, and uplifting to the creative human spirit.

Acute kidney injury (AKI) and fluids are closely linked through oliguria, which is a marker of the former and a trigger for administration of the latter. Recent progress in this field has challenged the physiological and clinical rational of using oliguria as a trigger for the administration of fluid and brought attention to the delicate balance between benefits and harms of different aspects of fluid management in critically ill patients, in particular those with AKI. This narrative review addresses various aspects of fluid management in AKI outlining physiological aspects, the effects of crystalloids and colloids on kidney function and the effect of various resuscitation and de-resuscitation strategies on the course and outcome of AKI.

Use of hypothermia in the intensive care unit

Used for over 3600 years, hypothermia, or targeted temperature management (TTM), remains an ill defined medical therapy. Currently, the strongest evidence for TTM in adults are for out-of-hospital ventricular tachycardia/ventricular fibrillation cardiac arrest, intracerebral pressure control, and normothermia in the neurocritical care population. Even in these disease processes, a number of questions exist. Data on disease specific therapeutic markers, therapeutic depth and duration, and prognostication are limited. Despite ample experimental data, clinical evidence for stroke, refractory status epilepticus, hepatic encephalopathy, and intensive care unit is only at the safety and proof-of-concept stage. This review explores the deleterious nature of fever, the theoretical role of TTM in the critically ill, and summarizes the clinical evidence for TTM in adults. PMID:24701408

Healthcare providers are increasingly expected to help chronically ill patients understand their own central role in managing their illness. The aim of this study was to determine whether experiencing high-quality chronic illness care and having a nurse involved in their care relate to chronically ill people's self-management. Survey data from 699 people diagnosed with chronic diseases who participated in a nationwide Dutch panel-study were analysed using linear regression analysis, to estimate the association between chronic illness care and various aspects of patients' self-management, while controlling for their socio-demographic and illness characteristics. Chronically ill patients reported that the care they received was of high quality to some extent. Patients who had contact with a practise nurse or specialised nurse perceived the quality of the care they received as better than patients who only had contact with a GP or medical specialist. Patients' perceptions of the quality of care were positively related to all aspects of their self-management, whereas contact with a practise nurse or specialised nurse in itself was not. Chronically ill patients who have the experience to receive high-quality chronic illness care that focusses on patient activation, decision support, goal setting, problem solving, and coordination of care are better self-managers. Having a nurse involved in their care seems to be positively valued by chronically ill patients, but does not automatically imply better self-management. Copyright © 2016.

Although the interfacility transport (IFT) of critically ill pediatric patients from rural to tertiary health centres may improve outcomes, the impact of IFTs on the rural referring centre is not known. The purpose of this study was to investigate how the IFT of critically ill children affects staffing and functionality of rural emergency departments (EDs) in Manitoba. In 2015, surveys were emailed to the medical directors of all 15 regional EDs within 2 hours' travel time from a tertiary pediatric hospital. The survey consisted of 9 questions that addressed baseline characteristics of the regional EDs and duration of ED staffing changes or closures due to IFT of critically ill pediatric patients. Ten surveys were received (67% response rate); a regional ED catchment population of about 130 000 people was represented. Interfacility transport caused most EDs (60%, with an average catchment population of 15 000) to close or to alter their staffing to a registered nurse only. These temporary changes lasted a cumulative total of 115 hours. Interfacility transport of critically ill pediatric patients resulted in ED closures and staffing changes in rural Manitoba. These findings suggest that long-term sustainable solutions are required to improve access to emergency care.

Role of inhibitory κB kinase and c-Jun NH2-terminal kinase in the development of hepatic insulin resistance in critical illness diabetes

PubMed Central

Jiang, Shaoning

2011-01-01

Hyperglycemia and insulin resistance induced by acute injuries or critical illness are associated with increased mortality and morbidity, as well as later development of type 2 diabetes. The molecular mechanisms underlying the acute onset of insulin resistance following critical illness remain poorly understood. In the present studies, the roles of serine kinases, inhibitory κB kinase (IKK) and c-Jun NH2-terminal kinase (JNK), in the acute development of hepatic insulin resistance were investigated. In our animal model of critical illness diabetes, activation of hepatic IKK and JNK was observed as early as 15 min, concomitant with the rapid impairment of hepatic insulin signaling and increased serine phosphorylation of insulin receptor substrate 1. Inhibition of IKKα or IKKβ, or both, by adenovirus vector-mediated expression of dominant-negative IKKα or IKKβ in liver partially restored insulin signaling. Similarly, inhibition of JNK1 kinase by expression of dominant-negative JNK1 also resulted in improved hepatic insulin signaling, indicating that IKK and JNK1 kinases contribute to critical illness-induced insulin resistance in liver.

Bacterial translocation as a direct cause of sepsis is an attractive hypothesis that presupposes that in specific situations bacteria cross the intestinal barrier, enter the systemic circulation, and cause a systemic inflammatory response syndrome. Critically ill children are at increased risk for bacterial translocation, particularly in the early postnatal age. Predisposing factors include intestinal obstruction, obstructive jaundice, intra-abdominal hypertension, intestinal ischemia/reperfusion injury and secondary ileus, and immaturity of the intestinal barrier per se. Despite good evidence from experimental studies to support the theory of bacterial translocation as a cause of sepsis, there is little evidence in human studies to confirm that translocation is directly correlated to bloodstream infections in critically ill children. This paper provides an overview of the gut microflora and its significance, a focus on the mechanisms employed by bacteria to gain access to the systemic circulation, and how critical illness creates a hostile environment in the gut and alters the microflora favoring the growth of pathogens that promote bacterial translocation. It also covers treatment with pre- and pro biotics during critical illness to restore the balance of microbial communities in a beneficial way with positive effects on intestinal permeability and bacterial translocation.

Reitz, André

2013-01-01

Critical illness polyneuropathy is a frequent complication of critical illness in intensive care units. Reports on autonomic systems like lower urinary tract and bowel functions in patients with CIP are not available in medical literature. This study performed during primary rehabilitation of patients with critical illness polyneuropathy explores if sensory and motor pathways controlling the lower urinary tract function are affected from the disease. Neurourological examinations, urodynamics, electromyography and lower urinary tract imaging were performed in 28 patients with critical illness polyneuropathy. Sacral sensation was impaired in 1 patient (4%). Sacral reflexes were absent in 8 patients (30%). Anal sphincter resting tone was reduced in 3 (12%), anal sphincter voluntary contraction was absent or reduced in 8 patients (30%). Urodynamic findings were detrusor overactivity and detrusor overactivity incontinence in 9 (37.5%), incomplete voiding in 8 (30%), abnormal sphincter activity in 4 (16%), abnormal bladder sensation in 4 (16%) and detrusor acontractility in 2 patients (8.3%). Morphological abnormalities of the lower urinary tract had 10 patients (41.6%). Sensory and motor pathways controlling the lower urinary tract might be affected from CIP. During urodynamics dysfunctions of the storage as well as the voiding phase were found. Morphological lower urinary tract abnormalities were common.

The management of diabetes during terminal illness is complex, with lack of agreement and consensus among physicians and multidisciplinary teams. Despite the plethora of guidelines available for the management of diabetes, there exists no agreed, evidence-based strategy for managing diabetes during terminal illness and at the end of life. A number of physiological factors may influence glycaemic control during terminal illness. These include anorexia, cachexia, malabsorption, renal and hepatic failure. Furthermore, controversy exists on the frequency of blood glucose monitoring, the optimum blood glucose range and how to achieve this. We review the factors influencing blood glucose during terminal illness and provide a suggested approach to managing patients with type 1 and type 2 diabetes during the early and late stages of terminal illness.

Objective Illness management and recovery is a structured program that helps consumers with severe mental illness learn effective ways to manage illness and pursue recovery goals. This study examined the impact of the program on health service utilization. Methods This was a retrospective cohort study of five assertive community treatment (ACT) teams in Indiana that implemented illness management and recovery. With Medicaid claims data from July 1, 2003, to June 30, 2008, panel data were created with person-months as the level of analysis, resulting in 14,261 observations, for a total of 498 unique individuals. Zero-inflated negative binomial regression models were used to predict hospitalization days and emergency room visits, including covariates of demographic characteristics, employment status, psychiatric diagnosis, and concurrent substance use disorder. The main predictor variables of interest were receipt of illness management and recovery services, dropout from the program, and program graduation status. Results Consumers who received some illness management and recovery services had fewer hospitalization days than those receiving only ACT. Graduates had fewer emergency room visits than did ACT-only consumers. Conclusions This is the first study to examine the impact of illness management and recovery on service utilization. Controlling for a number of background variables, the study showed that illness management and recovery programs were associated with reduced inpatient hospitalization and emergency room use over and above ACT.

Alterations in thyroid hormones during critical illness, known as non-thyroidal illness syndrome (NTIS), were suggested to have a prognostic value. However, pediatric data is limited. The aim of this study was to assess prevalence and prognostic value of NTIS among critically ill children. A prospective observational study conducted on 70 critically ill children admitted into pediatric intensive care unit (PICU). Free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) were measured within 24hours of PICU admission. Primary outcome was 30-day mortality. NTIS occurred in 62.9% of patients but it took several forms. The most common pattern was low FT3 with normal FT4 and TSH (25.7% of patients). Combined decrease in FT3, FT4, and TSH levels occurred in 7.1% of patients. An unusual finding of elevated TSH was noted in three patients, which might be related to disease severity. Low FT4 was significantly more prevalent among non-survivors compared with survivors (50% versus 19.2%, P=.028). NTIS independently predicted mortality (OR=3.91; 95% CI=1.006-15.19; P=.0491). Concomitant decrease in FT3, FT4, and TSH was the best independent predictor of mortality (OR=16.9; 95% CI=1.40-203.04; P=.026). TSH was negatively correlated with length of PICU stay (r s =-0.35, P=.011). FT3 level was significantly lower among patients who received dopamine infusion compared with those who did not receive it (2.1±0.66 versus 2.76±0.91pg/mL, P=.011). NTIS is common among critically ill children and appears to be associated with mortality and illness severity. Copyright © 2018. Publicado por Elsevier España, S.L.U.

Diaphragm Dysfunction in Critical Illness.

PubMed

Supinski, Gerald S; Morris, Peter E; Dhar, Sanjay; Callahan, Leigh Ann

2018-04-01

The diaphragm is the major muscle of inspiration, and its function is critical for optimal respiration. Diaphragmatic failure has long been recognized as a major contributor to death in a variety of systemic neuromuscular disorders. More recently, it is increasingly apparent that diaphragm dysfunction is present in a high percentage of critically ill patients and is associated with increased morbidity and mortality. In these patients, diaphragm weakness is thought to develop from disuse secondary to ventilator-induced diaphragm inactivity and as a consequence of the effects of systemic inflammation, including sepsis. This form of critical illness-acquired diaphragm dysfunction impairs the ability of the respiratory pump to compensate for an increased respiratory workload due to lung injury and fluid overload, leading to sustained respiratory failure and death. This review examines the presentation, causes, consequences, diagnosis, and treatment of disorders that result in acquired diaphragm dysfunction during critical illness.

To estimate federal dollars spent on critical care research, the cost of providing critical care, and to determine whether the percentage of federal research dollars spent on critical care research is commensurate with the financial burden of critical care. The National Institutes of Health Computer Retrieval of Information on Scientific Projects database was queried to identify funded grants whose title or abstract contained a key word potentially related to critical care. Each grant identified was analyzed by two reviewers (three if the analysis was discordant) to subjectively determine whether it was definitely, possibly, or definitely not related to critical care. Hospital and total costs of critical care were estimated from the Premier Database, state discharge data, and Medicare data. To estimate healthcare expenditures associated with caring for critically ill patients, total costs were calculated as the combination of hospitalization costs that included critical illness as well as additional costs in the year after hospital discharge. Of 19,257 grants funded by the National Institutes of Health, 332 (1.7%) were definitely related to critical care and a maximum of 1212 (6.3%) grants were possibly related to critical care. Between 17.4% and 39.0% of total hospital costs were spent on critical care, and a total of between $121 and $263 billion was estimated to be spent on patients who required intensive care. This represents 5.2% to 11.2%, respectively, of total U.S. healthcare spending. The proportion of research dollars spent on critical care is lower than the percentage of healthcare expenditures related to critical illness.

Treatment of critical ill patients in the intensive care unit is tantamount to well-designed risk or quality management. Several tools of quality management and quality assurance have been developed in intensive care medicine. In addition to external quality assurance by benchmarking with regard to the intensive care medicine, peer review procedures have been established for external quality assurance in recent years. In the process of peer review of an intensive care unit (ICU), external physicians and nurses visit the ICU, evaluate on-site proceedings, and discuss with the managing team of the ICU possibilities for optimization. Furthermore, internal quality management in the ICU is possible based on the 10 quality indicators of the German Interdisciplinary Society for Intensive Care Medicine (DIVI, "Deutschen Interdisziplinären Vereinigung für Intensiv- und Notfallmedizin"). Thereby every ICU has numerous possibilities to improve their quality management system.

Current empirical evidence supports claims that pain in sedated, unconscious Intensive Care Unit (ICU) patients is underrated and under-treated. Given the severity of ICU patients' illness pain management, whilst important, may not be considered a priority and therefore can be easily overlooked. The aim of this study was to validate the Behavioural Pain Scale (BPS) for the assessment of pain in critically ill patients by evaluating facial expressions, upper limb movements and compliance with mechanical ventilation. A prospective, descriptive repeated measures study design was used to assess the validity and reliability of the BPS for assessing pain in critically ill patients undergoing routine painful (repositioning) and non-painful (eye care) procedures. An average of 73% of BPS scores increased (indicating pain) after patients were repositioned, as opposed to 14% after eye care. This increase was statistically significant for repositioning (p < 0.003) but not for eye care (p > 0.3). The odds of an increase in BPS between pre- and post-procedure assessments was more than 25 times higher for repositioning compared with eye care (p < 0.0001), after controlling for analgesics and sedatives. The BPS was found to be a valid and reliable tool in the assessment of pain in the unconscious sedated patient. Results also highlighted that traditional pain indicators, such as fluctuations in haemodynamic parameters, are not always an accurate measure for the assessment of pain in unconscious patients and as such more objective pain assessment measures are essential. Finally, further validation of the BPS and identification of other painful routine procedures is needed to enhance pain management delivery for unconscious patients.

Growing evidence underscores the important role of glycemic control in health and recovery from illness. Carbohydrate ingestion in the diet or administration in nutritional support is mandatory, but carbohydrate intake can adversely affect major body organs and tissues if resulting plasma glucose becomes too high, too low, or highly variable. Plasma glucose control is especially important for patients with conditions such as diabetes or metabolic stress resulting from critical illness or surgery. These patients are particularly in need of glycemic management to help lessen glycemic variability and its negative health consequences when nutritional support is administered. Here we report on recent findings and emerging trends in the field based on an ESPEN workshop held in Venice, Italy, 8-9 November 2015. Evidence was discussed on pathophysiology, clinical impact, and nutritional recommendations for carbohydrate utilization and management in nutritional support. The main conclusions were: a) excess glucose and fructose availability may exacerbate metabolic complications in skeletal muscle, adipose tissue, and liver and can result in negative clinical impact; b) low-glycemic index and high-fiber diets, including specialty products for nutritional support, may provide metabolic and clinical benefits in individuals with obesity, insulin resistance, and diabetes; c) in acute conditions such as surgery and critical illness, insulin resistance and elevated circulating glucose levels have a negative impact on patient outcomes and should be prevented through nutritional and/or pharmacological intervention. In such acute settings, efforts should be implemented towards defining optimal plasma glucose targets, avoiding excessive plasma glucose variability, and optimizing glucose control relative to nutritional support.

Providing optimal care for critically ill and injured surgical patients will become more challenging with staff shortages for surgeons and intensivists. This white paper addresses the historical issues behind the present situation, the need for all intensivists to engage in dedicated critical care per the intensivist model, and the recognition that intensivists from all specialties can provide optimal care for the critically ill surgical patient, particularly with continuing involvement by the surgeon of record. The new acute care surgery training paradigm (including trauma, surgical critical care, and emergency general surgery) has been developed to increase interest in trauma and surgical critical care, but the number of interested trainees remains too few. Recommendations are made for broadening the multidisciplinary training and practice opportunities in surgical critical care for intensivists from all base specialties and for maintaining the intensivist model within acute care surgery practice. Support from academic and administrative leadership, as well as national organizations, will be needed.

Critically ill patients rapidly loose much of their muscle mass and strength. This can be attributed to prolonged admission, prolonged mechanical ventilation and increased mortality, and it can have a negative impact on the degree of independence and quality of life. In the NONSEDA trial we randomize critically ill patients to non-sedation or sedation with a daily wake-up trial during mechanical ventilation in the intensive care unit. It has never been assessed whether non-sedation affects physical function. The aim of this study is to assess the effects of non-sedation versus sedation with a daily wake-up trial on physical function after discharge from intensive care unit. Investigator-initiated, randomized, clinical, parallel-group, superiority trial, including 700 patients in total, with a substudy concerning 200 of these patients. Inclusion criteria will be intubated, mechanically ventilated patients with expected duration of mechanical ventilation >24 h. Exclusion criteria will be patients with severe head trauma, coma at admission or status epilepticus, patients treated with therapeutic hypothermia, patients with PaO2/FiO2<9 where sedation might be necessary to ensure sufficient oxygenation or placing the patient in a prone position. The experimental intervention will be non-sedation supplemented with pain management during mechanical ventilation. The control intervention will be sedation with a daily wake-up trial. The co-primary outcome will be quality of life regarding physical function (SF-36, physical component) and degree of independence in activities of daily living (Barthel Index), and this will be assessed for all 700 patients participating in the NONSEDA trial. The secondary outcomes, which will be assessed for the subpopulation of 200 NONSEDA patients in the trial site, Kolding, will be 6-min walking distance, handgrip strength, muscle size (ultrasonographic measurement of the rectus femoris muscle cross-sectional area) and biomechanical data on lower extremity function (maximal voluntary contraction, rate of force development and endurance). This study is the first to investigate the effect of no sedation during critical illness on physical function. If an effect is found, it will add important information on how to prevent muscle weakness following critical illness. The study has been approved by the relevant scientific ethics committee and is registered at ClinicalTrials.gov (ID: NCT02034942, 9 January 2014).

The threatened self: Considerations of time, place, and uncertainty in advanced illness.

2016-05-01

Loss of self and the transition to patient-hood have been widely discussed in relation to the experience of advanced illness. Individuals however often maintain identities or selves beyond those demanded by the circumstances of being a patient. This study explores the presentation of this personal identity and interactions between intrinsic and extrinsic elements that support or threaten its maintenance. In particular, this study examined the impact of uncertainty on the representations of self and the part played by the patient's health care professionals and the systems in which they are embedded, in limiting or reinforcing its effects. Complementary methods of ethnographic observation and serial narrative interviews were adopted to explore both the lo"cal social and health care context and the changing presentation of self by patients with advanced multimorbidity, chronic illness, and cancer. In total, 36 interviews were undertaken with 16 patients. Analysis was guided by concepts of time and place, combining contextual data with the unfolding patient narrative. Good pain and symptom control was a necessary, but not sufficient, condition for the maintenance of a personal identity. Essential agentic elements included knowledge of appropriate and immediate sources of help. Also important were a sense of control achieved through a shared understanding with health care professionals of the condition and active management of uncertainty. In addition, the maintenance of self depended on keeping a connection with aspects of life associated with a pre-illness identity. Critically, this self was contingent on external recognition, acknowledgement, and validation. Professional relationships that focus solely on the 'person as patient' may be insufficient for patients' needs. Health care professionals should seek to recognize and acknowledge the personal identity that may be critical to their sense of self-worth. Through an ongoing relationship guiding the patient through the uncertainties they face, health care professionals may play an essential role in sustaining the 'patient as person'. What is already known on this subject? Loss of self or personal identity occurs in a range of serious conditions. The sick self is incorporated in a process of identity reconstruction. Uncertainty is an inherent aspect of serious and advanced illness. Unmanaged uncertainty results in a range of negative psychological consequences that contribute to the loss of personal identity. Information and communication with health care professionals help patients manage uncertainty. What does this study add? Sufferers may retain a personal identity continuous with a pre-illness self using internal and external resources. The pre-illness self may be subsumed by the patient self especially at times of transition and maximum uncertainty. Acknowledgement and facilitation by health care professionals can enable the preservation of the pre-illness self. © 2015 The British Psychological Society.

Pneumonia is the leading infectious cause of death in children worldwide. Each year, pneumonia kills an estimated 935,000 children under five years of age, with most of these deaths occurring in developing countries. The current approach for pneumonia diagnosis in low-resource settings—using the World Health Organization Integrated Management of Childhood Illness (IMCI) paper-based protocols and relying on a health care provider’s ability to manually count respiratory rate—has proven inadequate. Furthermore, hypoxemia—a diagnostic indicator of the presence and severity of pneumonia often associated with an increased risk of death—is not assessed because pulse oximetry is frequently not available in low-resource settings. In an effort to address childhood pneumonia mortality and improve frontline health care providers’ ability to diagnose, classify, and manage pneumonia and other childhood illnesses, PATH collaborated with the University of Washington to develop “mPneumonia,” an innovative mobile health application using an Android tablet. mPneumonia integrates a digital version of the IMCI algorithm with a software-based breath counter and a pediatric pulse oximeter. We conducted a design-stage usability field test of mPneumonia in Ghana, with the goal of creating a user-friendly diagnostic and management tool for childhood pneumonia and other childhood illnesses that would improve diagnostic accuracy and facilitate adherence by health care providers to established guidelines in low-resource settings. The results of the field test provided valuable information for understanding the usability and acceptability of mPneumonia among health care providers, and identifying approaches to iterate and improve. This critical feedback helped ascertain the common failure modes related to the user interface design, navigation, and accessibility of mPneumonia and the modifications required to improve user experience and create a tool aimed at decreasing mortality from pneumonia and other childhood illnesses in low-resource settings.

Background & aims The reference method to study protein and arginine metabolism in critically ill children is measuring plasma amino acid appearances with stable isotopes during a short (4–8h) time period and extrapolate results to 24-hour. However, 24-hour measurements may be variable due to critical illness related factors and a circadian rhythm could be present. Since only short duration stable isotope studies in critically ill children have been conducted before, the aim of this study was to investigate 24-hour appearance of specific amino acids representing protein and arginine metabolism, with stable isotope techniques in continuously fed critically ill children. Methods In eight critically ill children, admitted to the pediatric (n=4) or cardiovascular (n=4) intensive care unit, aged 0–10 years, receiving continuous (par)enteral nutrition with protein intake 1.0–3.7 g/kg/day, a 24-hour stable isotope tracer protocol was carried out. L-[ring-2H5]-phenylalanine, L-[3,3-2H2]-tyrosine, L-[5,5,5-2H3]-leucine, L-[guanido-15N2]-arginine and L-[5-13C-3,3,4,4-2H4]-citrulline were infused intravenously and L-[15N]-phenylalanine and L-[1-13C]leucine enterally. Arterial blood was sampled every hour. Results Coefficients of variation, representing intra-individual variability, of the amino acid appearances of phenylalanine, tyrosine, leucine, arginine and citrulline were high, on average 14–19% for intravenous tracers and 23–26% for enteral tracers. No evident circadian rhythm was present. The pattern and overall 24-hour level of whole body protein balance differed per individual. Conclusions In continuously fed stable critically ill children, the amino acid appearances of phenylalanine, tyrosine, leucine, arginine and citrulline show high variability. This should be kept in mind when performing stable isotope studies in this population. There was no apparent circadian rhythm. PMID:28089618

Study Objectives: Although empirical evidence is limited, critical illness in children is associated with disruption of the normal sleep-wake rhythm. The objective of the current study was to examine the temporal characteristics of the sleep electroencephalogram (EEG) in a sample of children with critical illness. Methods: Limited montage EEG recordings were collected for at least 24 hours from 8 critically ill children on mechanical ventilation for respiratory failure in a pediatric intensive care unit (PICU) of a tertiary-care hospital. Each PICU patient was age- and gender-matched to a healthy subject from the community. Power spectral analysis with the fast Fourier transform (FFT) was used to characterize EEG spectral power and categorized into 4 frequency bands: δ (0.8 to 4.0 Hz), θ (4.1 to 8.0 Hz), α (8.1 to 13.0 Hz), and β1/β2 (13.1 to 20.0 Hz). Results: PICU patients did not manifest the ultradian variability in EEG power spectra including the typical increase in δ-power during the first third of the night that was observed in healthy children. Differences noted included significantly lower mean nighttime δ and θ power in the PICU patients compared to healthy children (p < 0.001). Moreover, in the PICU patients, mean δ and θ power were higher during daytime hours than nighttime hours (p < 0.001). Conclusions: The results presented herein challenge the assumption that children experience restorative sleep during critical illness, highlighting the need for interventional studies to determine whether sleep promotion improves outcomes in critically ill children undergoing active neurocognitive development.

To identify the relationships between advance directive status, demographic characteristics and decisional burden (role stress and depressive symptoms) of surrogate decision-makers (SDMs) of patients with chronic critical illness. Although the prevalence of advance directives among Americans has increased, SDMs are ultimately responsible for complex medical decisions of the chronically critically ill patient. Decisional burden has lasting psychological effects on SDMs. There is insufficient evidence on the influence of advance directives on the decisional burden of surrogate decision-makers of patients with chronic critical illness. The study was a secondary data analysis of cross-sectional data. Data were obtained from 489 surrogate decision-makers of chronically critically ill patients at two academic medical centres in Northeast Ohio, United States, between September 2005-May 2008. Data were collected using demographic forms and questionnaires. A single-item measure of role stress and the Center for Epidemiological Studies Depression (CESD) scale were used to capture the SDM's decisional burden. Descriptive statistics, t-tests, chi-square and path analyses were performed. Surrogate decision-makers who were nonwhite, with low socioeconomic status and low education level were less likely to have advance directive documentation for their chronically critically ill patient. The presence of an advance directive mitigates the decisional burden by directly reducing the SDM's role stress and indirectly lessening the severity of depressive symptoms. Most SDMs of chronically critically ill patients will not have the benefit of knowing the patient's preferences for life-sustaining therapies and consequently be at risk of increased decisional burden. Study results are clinically useful for patient education on the influence of advance directives. Patients may be informed that SDMs without advance directives are at risk of increased decisional burden and will require decisional support to facilitate patient-centred decision-making. © 2013 John Wiley & Sons Ltd.

Being chronically ill is a continuous process of balancing the demands of the illness and the demands of everyday life. Understanding how everyday life affects self-management might help to provide better professional support. However, little attention has been paid to the influence of everyday life on self-management. The purpose of this study is to examine to what extent problems in everyday life interfere with the self-management behaviour of people with chronic illness, i.e. their ability to manage their illness. To estimate the effects of having everyday problems on self-management, cross-sectional linear regression analyses with propensity score matching were conducted. Data was used from 1731 patients with chronic disease(s) who participated in a nationwide Dutch panel-study. One third of people with chronic illness encounter basic (e.g. financial, housing, employment) or social (e.g. partner, children, sexual or leisure) problems in their daily life. Younger people, people with poor health and people with physical limitations are more likely to have everyday problems. Experiencing basic problems is related to less active coping behaviour, while experiencing social problems is related to lower levels of symptom management and less active coping behaviour. The extent of everyday problems interfering with self-management of people with chronic illness depends on the type of everyday problems encountered, as well as on the type of self-management activities at stake. Healthcare providers should pay attention to the life context of people with chronic illness during consultations, as patients' ability to manage their illness is related to it.

Clinical risk management in mental health: a qualitative study of main risks and related organizational management practices

PubMed Central

2013-01-01

Background A scientific understanding of clinical risk management (CRM) in mental health care is essential for building safer health systems and for improving patient safety. While evidence on patient safety and CRM in physical health care has increased, there is limited research on these issues in mental health care. This qualitative study provides an overview of the most important clinical risks in mental health and related organizational management practices. Methods We conducted in-depth expert interviews with professionals responsible for CRM in psychiatric hospitals. Interviews were transcribed and analyzed applying qualitative content analysis to thematically sort the identified risks. Results The main concerns for CRM in mental health are a) violence and self-destructive behavior (i.e. protecting patients and staff from other patients, and patients from themselves), b) treatment errors, especially in the process of therapy, and c) risks associated with mental illnesses (e.g. psychosis or depression). This study identified critical differences to CRM in hospitals for physical disorder and challenges specific to CRM in mental health. Firstly, many psychiatric patients do not believe that they are ill and are therefore in hospital against their will. Secondly, staff safety is a much more prominent theme for CRM in mental health care as it is directly related to the specifics of mental illnesses. Conclusions The current study contributes to the understanding of patient safety and raises awareness for CRM in mental health. The mental health specific overview of central risks and related organizational management practices offers a valuable basis for CRM development in mental health and an addition to CRM in general.

Routine post-operative care in high dependency unit (HDU), surgical intensive care unit (SICU) and intensive care unit (ICU) after high-risk gynaecological oncology surgical procedures may allow for greater recognition and correct management of post-operative complications, thereby reducing long-term morbidity and mortality. On the other hand, unnecessary admissions to these units lead to increased morbidity - nosocomial infections, increased length of hospital stay and higher hospital costs. Gynaecological oncology surgeons continue to look after their patient in the HDU/SICU and have the final role in decision-making on day-to-day basis, making it important to be well versed in critical care management and ensure the best care for their patients. Post-operative monitoring and the presence of comorbid illnesses are the most common reasons for admission to the HDU/SICU. Elderly and malnutritioned patients, as well as, bowel resection, blood loss or greater fluid resuscitation during the surgery have prolonged HDU/SICU stay. Patients with ovarian cancer have a worse survival outcome than the patients with other types of gynaecological cancer. Dependency care is a part of surgical management and it should be incorporated formally into gynaecologic oncology training programme. © 2016 John Wiley & Sons Ltd.

2012-01-01

Background The practice of glycemic control with intravenous insulin in critically ill patients has brought clinical focus on understanding the effects of hypoglycemia, especially in children. Very little is published on the impact of hypoglycemia in this population. We aimed to review the existing literature on hypoglycemia in critically ill neonates and children. Methods We performed a systematic review of the literature up to August 2011 using PubMed, Ovid MEDLINE and ISI Web of Science using the search terms “hypoglycemia or hypoglyc*” and “critical care or intensive care or critical illness”. Articles were limited to “all child (0–18 years old)” and “English”. Results A total of 513 articles were identified and 132 were included for review. Hypoglycemia is a significant concern among pediatric and neonatal intensivists. Its definition is complicated by the use of a biochemical measure (i.e., blood glucose) for a pathophysiologic problem (i.e., neuroglycopenia). Based on associated outcomes, we suggest defining hypoglycemia as <40–45 mg/dl in neonates and <60–65 mg/dl in children. Below the suggested threshold values, hypoglycemia is associated with worse neurological outcomes, increased intensive care unit stay, and increased mortality. Disruptions in carbohydrate metabolism increase the risk of hypoglycemia incritically ill children. Prevention of hypoglycemia, especially in the setting of intravenous insulin use, will be best accomplished by the combination of accurate measuring techniques, frequent or continuous glucose monitoring, and computerized insulin titration protocols. Conclusion Studies on hypoglycemia in critically ill children have focused on spontaneous hypoglycemia. With the current practice of maintaining blood glucose within a narrow range with intravenous insulin, the risk factors and outcomes associated with insulin-induced hypoglycemia should be rigorously studied to prevent hypoglycemia and potentially improve outcomes of critically ill children.

Introduction Critically ill patients suffer from oxidative stress caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS). Although ROS/RNS are constantly produced under normal circumstances, critical illness can drastically increase their production. These patients have reduced plasma and intracellular levels of antioxidants and free electron scavengers or cofactors, and decreased activity of the enzymatic system involved in ROS detoxification. The pro-oxidant/antioxidant balance is of functional relevance during critical illness because it is involved in the pathogenesis of multiple organ failure. In this study the objective was to evaluate the relation between oxidative stress in critically ill patients and antioxidant vitamin intake and severity of illness. Methods Spectrophotometry was used to measure in plasma the total antioxidant capacity and levels of lipid peroxide, carbonyl group, total protein, bilirubin and uric acid at two time points: at intensive care unit (ICU) admission and on day seven. Daily diet records were kept and compliance with recommended dietary allowance (RDA) of antioxidant vitamins (A, C and E) was assessed. Results Between admission and day seven in the ICU, significant increases in lipid peroxide and carbonyl group were associated with decreased antioxidant capacity and greater deterioration in Sequential Organ Failure Assessment score. There was significantly greater worsening in oxidative stress parameters in patients who received antioxidant vitamins at below 66% of RDA than in those who received antioxidant vitamins at above 66% of RDA. An antioxidant vitamin intake from 66% to 100% of RDA reduced the risk for worsening oxidative stress by 94% (ods ratio 0.06, 95% confidence interval 0.010 to 0.39), regardless of change in severity of illness (Sequential Organ Failure Assessment score). Conclusion The critical condition of patients admitted to the ICU is associated with worsening oxidative stress. Intake of antioxidant vitamins below 66% of RDA and alteration in endogenous levels of substances with antioxidant capacity are related to redox imbalance in critical ill patients. Therefore, intake of antioxidant vitamins should be carefully monitored so that it is as close as possible to RDA. PMID:17040563

Utility of CT-compatible EEG electrodes in critically ill children.

Abend, Nicholas S; Dlugos, Dennis J; Zhu, Xiaowei; Schwartz, Erin S

2015-04-01

Electroencephalographic monitoring is being used with increasing frequency in critically ill children who may require frequent and sometimes urgent brain CT scans. Standard metallic disk EEG electrodes commonly produce substantial imaging artifact, and they must be removed and later reapplied when CT scans are indicated. To determine whether conductive plastic electrodes caused artifact that limited CT interpretation. We describe a retrospective cohort of 13 consecutive critically ill children who underwent 17 CT scans with conductive plastic electrodes during 1 year. CT images were evaluated by a pediatric neuroradiologist for artifact presence, type and severity. All CT scans had excellent quality images without artifact that impaired CT interpretation except for one scan in which improper wire placement resulted in artifact. Conductive plastic electrodes do not cause artifact limiting CT scan interpretation and may be used in critically ill children to permit concurrent electroencephalographic monitoring and CT imaging.

Diastolic dysfunction in the critically ill patient.

Left ventricular diastolic dysfunction is a common finding in critically ill patients. It is characterized by a progressive deterioration of the relaxation and the compliance of the left ventricle. Two-dimensional and Doppler echocardiography is a cornerstone in its diagnosis. Acute pulmonary edema associated with hypertensive crisis is the most frequent presentation of diastolic dysfunction critically ill patients. Myocardial ischemia, sepsis and weaning failure from mechanical ventilation also may be associated with diastolic dysfunction. The treatment is based on the reduction of pulmonary congestion and left ventricular filling pressures. Some studies have found a prognostic role of diastolic dysfunction in some diseases such as sepsis. The present review aims to analyze thoroughly the echocardiographic diagnosis and the most frequent scenarios in critically ill patients in whom diastolic dysfunction plays a key role.

The UK National Health Service (NHS) is regularly restructured. Its smooth operation and organisational memory depends on the insights and capability of managers, especially those with experience of previous transitions. Narrative methods can illuminate complex change from the perspective of key actors. We used an adaptation of Wengraf's biographical narrative life interview method to explore how 20 senior NHS managers (chief executives, directors and assistant directors) had perceived and responded to major transitions since 1974. Data were analysed thematically using insights from phenomenology, neo-institutional theory and critical management studies. Findings were contextualised within a literature review of NHS policy and management 1974-2009. Managers described how experience in different NHS organisations helped build resilience and tacit knowledge, and how a strong commitment to the 'NHS brand' allowed them to weather a succession of policy changes and implement and embed such changes locally. By synthesising these personal and situated micro-narratives, we built a wider picture of macro-level institutional change in the NHS, in which the various visible restructurings in recent years appear to have masked a deeper continuity in terms of enduring values, norms and ways of working. We consider the implications of these findings for the future NHS. © 2011 The Authors. Sociology of Health & Illness © 2011 Foundation for the Sociology of Health & Illness/Blackwell Publishing Ltd.

This is a state-of-the-art article of the diagnostic process, etiologies and management of acute right ventricular (RV) failure in critically ill patients. It is based on a large review of previously published articles in the field, as well as the expertise of the authors. The authors propose the ten key points and directions for future research in the field. RV failure (RVF) is frequent in the ICU, magnified by the frequent need for positive pressure ventilation. While no universal definition of RVF is accepted, we propose that RVF may be defined as a state in which the right ventricle is unable to meet the demands for blood flow without excessive use of the Frank-Starling mechanism (i.e. increase in stroke volume associated with increased preload). Both echocardiography and hemodynamic monitoring play a central role in the evaluation of RVF in the ICU. Management of RVF includes treatment of the causes, respiratory optimization and hemodynamic support. The administration of fluids is potentially deleterious and unlikely to lead to improvement in cardiac output in the majority of cases. Vasopressors are needed in the setting of shock to restore the systemic pressure and avoid RV ischemia; inotropic drug or inodilator therapies may also be needed. In the most severe cases, recent mechanical circulatory support devices are proposed to unload the RV and improve organ perfusion CONCLUSION: RV function evaluation is key in the critically-ill patients for hemodynamic management, as fluid optimization, vasopressor strategy and respiratory support. RV failure may be diagnosed by the association of different devices and parameters, while echocardiography is crucial.

The management of intravenous (IV) fluid temperature is a daily challenge in critical care, anesthesiology, and emergency medicine. Infusion of IV fluids at the right temperature partly influences clinical outcomes of critically ill patients. Nowadays, intravenous fluid temperature is poorly managed, as no suitable device is routinely available. Infrared (IR) thermometers have been recently developed for industrial, personal, or medical purposes. The aim of this study was to evaluate the accuracy of an IR thermometer in measuring temperature of warmed and cooled infusion fluids in fluid bags. This study compared temperatures simultaneously recorded by an infrared thermometer and a temperature sensor. Temperatures of warmed (41 degrees C) and cooled (4 degrees C) infusion fluids in fluid bags were recorded by 2 independent operators every minute until IV bags' temperature reached ambient temperature. The relation curve was established with 576 measures. Temperature measures performed with an IR thermometer were perfectly linear and perfectly correlated with the reference method (R(2) = 0.995, P < 10(-5)). Infrared thermometers are efficient to measure IV fluid bag temperature in the range of temperatures used in clinical practice. As these devices are easy to use and inexpensive, they could be largely used in critical care, anesthesiology, or emergency medicine.

To identify and describe the outcomes of a nurse-led intervention, "Health-promoting conversations with families," regarding family functioning and well-being in families with a member who was critically ill. Families who have a critically ill family member in an intensive care unit face a demanding situation, threatening the normal functioning of the family. Yet, there is a knowledge gap regarding family members' well-being during and after critical illness. The study used a qualitative inductive-descriptive design. Eight families participated in health-promoting conversations aimed to create a context for change related to the families' identified problems and resources. Fifteen qualitative interviews were conducted with 18 adults who participated in health-promoting conversations about a critical illness in the family. Eight participants were patients (six men, two women) and 10 were family members (two male partners, five female partners, one mother, one daughter, one female grandchild). The interviews were analysed by conventional content analysis. Family members experienced strengthened togetherness, a caring attitude and confirmation through health-promoting conversations. The caring and calming conversations were appreciated despite the reappearance of exhausting feelings. Working through the experience and being confirmed promoted family well-being. Health-promoting conversations were considered to be healing, as the family members take part in sharing each other's feelings, thoughts and experiences with the critical illness. Health-promoting conversations could be a simple and effective nursing intervention for former intensive care patients and their families in any cultural context. © 2017 John Wiley & Sons Ltd.

Introduction Regional citrate anticoagulation (RCA) is gaining popularity in continous renal replacement therapy (CRRT) for critically ill patients. The risk of citrate toxicity is a primary concern during the prolonged process. The aim of this study was to assess the pharmacokinetics of citrate in critically ill patients with AKI, and used the kinetic parameters to predict the risk of citrate accumulation in this population group undergoing continuous veno-venous hemofiltration (CVVH) with RCA. Methods Critically ill patients with AKI (n = 12) and healthy volunteers (n = 12) were investigated during infusing comparative dosage of citrate. Serial blood samples were taken before, during 120 min and up to 120 min after infusion. Citrate pharmacokinetics were calculated and compared between groups. Then the estimated kinetic parameters were applied to the citrate kinetic equation for validation in other ten patients’ CVVH sessions with citrate anticoagulation. Results Total body clearance of citrate was similar in critically ill patients with AKI and healthy volunteers (648.04±347.00 L/min versus 686.64±353.60 L/min; P = 0.624). Basal and peak citrate concentrations were similar in both groups (p = 0.423 and 0.247, respectively). The predicted citrate curve showed excellent fit to the measurements. Conclusions Citrate clearance is not impaired in critically ill patients with AKI in the absence of severe liver dysfunction. Citrate pharmacokinetic data can provide a basis for the clinical use of predicting the risk of citrate accumulation. Trial Registration ClinicalTrials.gov Identifier NCT00948558 PMID:23824037

Critically ill patients are at increased risk of developing malnutrition-related complications because of physiological changes, suboptimal delivery, and reduced intake. Strategies to improve nutrition during critical illness recovery are required to prevent iatrogenic underfeeding and risk of malnutrition. The purpose of this study was to assess the feasibility and acceptability of a novel family-centered intervention to improve nutrition in critically ill patients. A 3-phase, prospective cohort feasibility study was conducted in 4 intensive care units (ICUs) across 2 countries. Intervention feasibility was determined by patient eligibility, recruitment, and retention rates. The acceptability of the intervention was assessed by participant perspectives collected through surveys. Participants included family members of the critically ill patients and ICU and ward healthcare professionals (HCPs). A total of 75 patients and family members, as well as 56 HCPs, were enrolled. The consent rate was 66.4%, and 63 of 75 (84%) of family participants completed the study. Most family members (53/55; 98.1%) would recommend the nutrition education program to others and reported improved ability to ask questions about nutrition (16/20; 80.0%). Family members viewed nutrition care more positively in the ICU. HCPs agreed that families should partner with HCPs to achieve optimal nutrition in the ICU and the wards. Health literacy was identified as a potential barrier to family participation. The intervention was feasible and acceptable to families of critically ill patients and HCPs. Further research to evaluate intervention impact on nutrition intake and patient-centered outcomes is required.

Inflammation, a common problem for patients in the intensive care unit (ICU), frequently is associated with serious and prolonged critical illnesses. To date, no study has examined whether physical activity influences inflammatory factors in critically ill adults. The objectives of this study were to (a) examine the relationships between type and duration of physical activity and serum levels of interleukin 6 (IL-6), a proinflammatory cytokine; IL-10, an anti-inflammatory cytokine; and their ratio and (b) determine if there are associations between cytokines or their ratio and activity or outcomes. This descriptive feasibility study investigated the approaches to measuring levels of physical activity and its relationship to serum levels of IL-6 and IL-10 and the ratio between them in patients with prolonged mechanical ventilation during periods of activity and rest. Measurements included serum IL-6 and IL-10 levels, direct observation and actigraphy, and prospective chart review. Ten critically ill patients who were mechanically ventilated for an average of 10 days in a large, urban, teaching hospital were enrolled. The average ratio of IL-6 to IL-10 improved after an average of 14.7 min of passive physical activity, typically multiple in-bed turns associated with hygiene. IL-6, IL-10, and their ratio were not associated with patient outcomes of weaning success or length of stay. High levels of IL-6 were associated with mortality. Cytokine balance may be improved by low levels of activity among patients with prolonged critical illness. The pattern of cytokines produced after activity may improve patients' recovery from prolonged critical illness and mechanical ventilation.

Although empirical evidence is limited, critical illness in children is associated with disruption of the normal sleep-wake rhythm. The objective of the current study was to examine the temporal characteristics of the sleep electroencephalogram (EEG) in a sample of children with critical illness. Limited montage EEG recordings were collected for at least 24 hours from 8 critically ill children on mechanical ventilation for respiratory failure in a pediatric intensive care unit (PICU) of a tertiary-care hospital. Each PICU patient was age- and gender-matched to a healthy subject from the community. Power spectral analysis with the fast Fourier transform (FFT) was used to characterize EEG spectral power and categorized into 4 frequency bands: δ (0.8 to 4.0 Hz), θ (4.1 to 8.0 Hz), α (8.1 to 13.0 Hz), and β1/β2 (13.1 to 20.0 Hz). PICU patients did not manifest the ultradian variability in EEG power spectra including the typical increase in δ-power during the first third of the night that was observed in healthy children. Differences noted included significantly lower mean nighttime δ and θ power in the PICU patients compared to healthy children (p < 0.001). Moreover, in the PICU patients, mean δ and θ power were higher during daytime hours than nighttime hours (p < 0.001). The results presented herein challenge the assumption that children experience restorative sleep during critical illness, highlighting the need for interventional studies to determine whether sleep promotion improves outcomes in critically ill children undergoing active neurocognitive development. © 2015 American Academy of Sleep Medicine.

To determine, based on indirect calorimetry measurements, the biases of predictive equations specifically developed recently for estimating resting energy expenditure (REE) in ventilated critically ill children, or developed for healthy populations but used in critically ill children. A secondary analysis study was performed using our data on REE measured in a previous prospective study on protein and energy needs in pediatric intensive care unit. We included 75 ventilated critically ill children (median age, 21 months) in whom 407 indirect calorimetry measurements were performed. Fifteen predictive equations were used to estimate REE: the equations of White, Meyer, Mehta, Schofield, Henry, the World Health Organization, Fleisch, and Harris-Benedict and the tables of Talbot. Their differential and proportional biases (with 95% CIs) were computed and the bias plotted in graphs. The Bland-Altman method was also used. Most equations underestimated and overestimated REE between 200 and 1000 kcal/day. The equations of Mehta, Schofield, and Henry and the tables of Talbot had a bias ≤10%, but the 95% CI was large and contained values by far beyond ±10% for low REE values. Other specific equations for critically ill children had even wider biases. In ventilated critically ill children, none of the predictive equations tested met the performance criteria for the entire range of REE between 200 and 1000 kcal/day. Even the equations with the smallest bias may entail a risk of underfeeding or overfeeding, especially in the youngest children. Indirect calorimetry measurement must be preferred.

Phenytoin is a common medication for seizure treatment and prophylaxis in the intensive care unit (ICU). The clinical utility of the Sheiner-Tozer equation for adjusting total phenytoin levels for hypoalbuminemia remains controversial. The purpose of this study was to evaluate the correlation of this formula in predicting phenytoin serum concentrations. A retrospective cohort study was conducted in the adult ICU between January 1, 2010, and June 21, 2013. Patients meeting the following study criteria were included: age ≥18 years, admission to the ICU, simultaneously drawn total and free serum phenytoin concentrations with albumin ≤48 hours of phenytoin draws. Study end points were the correlation as well as the level of agreement in the interpretation of the free and adjusted phenytoin concentrations using the Sheiner-Tozer formula in critically ill patients with hypoalbuminemia. A total of 238 patients were analyzed. Mean adjusted total phenytoin and free levels were 16.1 ± 8.1 and 1.5 ± 0.8 µg/mL, respectively (r = 0.817; P < 0.001). Absolute agreement with level interpretation between adjusted total phenytoin and free levels was 77% (κ = 0.633; P < 0.001). Adjusted phenytoin serum concentrations more frequently overestimated the free level. There is a significant correlation between free and adjusted total phenytoin levels using the Sheiner-Tozer equation in critically ill patients. However, disagreement was noted with interpretation, primarily because of the adjusted concentration overestimating the free level. This imprecision may lead to inaccurate decision making regarding the management of phenytoin in this patient population. Thus, free phenytoin levels should be utilized. © The Author(s) 2016.

Major Mental Illness in Those Who Sexually Abuse.

2017-11-09

There is evidence showing an increasing prevalence of mental illness in those in conflict with the law. However, there are many factors affecting the detection, treatment, and management of criminals who are mentally ill. Sex offenders with major mental illness present many challenges to those providing treatment and management services. For example, it is important to consider whether sexually offensive behavior is the cause of criminal behavior or whether it is reflective of an antisocial orientation. Recent evidence suggests it may help better understand and inform risk assessment and management. This paper will review the literature on mental illness among sexual offenders, present a typology to aid in the assessment, treatment, and management of sexual offender with mental illness, and highlight important considerations when providing treatment to sexual offenders with mental illness.

The interfacility transport of critically ill newborns

The practice of paediatric/neonatal interfacility transport continues to expand. Transport teams have evolved into mobile intensive care units capable of delivering state-of-the-art critical care during paediatric and neonatal transport. While outcomes are best for high-risk infants born in a tertiary care setting, high-risk mothers often cannot be safely transferred. Their newborns may then have to be transported to a higher level of care following birth. The present statement reviews issues relating to transport of the critically ill newborn population, including personnel, team competencies, skills, equipment, systems and processes. Six recommendations for improving interfacility transport of critically ill newborns are highlighted, emphasizing the importance of regionalized care for newborns. PMID:26175564

Critical illness in paediatric patients includes acute conditions in a healthy child as well as exacerbations of chronic disease, and therefore these situations must be clinically managed in Critical Care Units. The role of the paediatric nurse is to ensure the comfort of these critically ill patients. To that end, instruments are required that correctly assess critical comfort. To describe the process for validating the content of a paediatric critical comfort scale using mixed-method research. Initially, a cross-cultural adaptation of the Comfort Behavior Scale from English to Spanish using the translation and back-translation method was made. After that, its content was evaluated using mixed method research. This second step was divided into a quantitative stage in which an ad hoc questionnaire was used in order to assess each scale's item relevance and wording and a qualitative stage with two meetings with health professionals, patients and a family member following the Delphi Method recommendations. All scale items obtained a content validity index >0.80, except physical movement in its relevance, which obtained 0.76. Global content scale validity was 0.87 (high). During the qualitative stage, items from each of the scale domains were reformulated or eliminated in order to make the scale more comprehensible and applicable. The use of a mixed-method research methodology during the scale content validity phase allows the design of a richer and more assessment-sensitive instrument.

Septic acute kidney injury (AKI) accounts for more than half of all cases of AKI in critically ill children. The renal histology was found to alter the management in more than two-third of cases of adult acute renal failure. Better insight into the pathogenesis of pediatric septic AKI could be based on developing a clearer appreciation of the histopathological changes. No comprehensive study of the histopathological features of septic AKI in critically ill children has yet been performed. This retrospective observational study was conducted at a level-III pediatric intensive care unit (PICU) from June 2013 to July 2014. Children (<13 years of age) who had expired due to sepsis and AKI and had post-mortem renal biopsies were included. Sepsis and AKI were defined according to the International pediatric sepsis consensus conference and Acute Kidney Injury Network (AKIN) definition and classification system, respectively. A total of 708 patients were admitted to the PICU during the study period, with mortality of 24 % (n = 170) and 62 complete data of post-mortem renal biopsies were included. The median (IQR) age was 12 (4.8-36) months, pediatric risk of mortality score (PRISM) III was 14 (12-18) and the time to biopsy after death was 24 (18-26) minutes. Normal histology was the most common change 41.9 % (n = 26), followed by acute tubular necrosis (ATN) 30.6 % (n = 19). A combination of changes involving tubules, glomeruli, interstitium, and blood vessels was noted in 21 % (n = 13) of the specimens. Eight percent (n = 5) of the specimens had features consistent with thrombotic microangiopathy. Normal histology was noted in 15.4 % (n = 4/26), 50 % (n = 13/26), and 34.6 % (n = 9/26) of AKI stage-I, II, and III, respectively. The most common renal histopathological change in septic AKI in critically ill children was normal histology followed by ATN.

Aim To identify factors that may serve as facilitators and barriers to self-management described by adults living with chronic illness by conducting a qualitative metasynthesis. Background Self-management is an individuals’ active management of a chronic illness in collaboration with their family members and clinicians. Design Qualitative metasynthesis. Data Sources We analyzed studies (N=53) published between January 2000–May 2013 that described factors affecting self-management in chronic illness as reported by adults aged over 18 years with chronic illness. Review Methods Sandelowsi and Barroso approach to qualitative metasynthesis: literature search; quality appraisal; analysis; and synthesis of findings. Results Collectively, article authors reported on sixteen chronic illnesses, most commonly diabetes (N=28) and cardiovascular disease (N=20). Participants included men and women (mean age=57, range 18–94) from twenty countries representing diverse races and ethnicities. We identified five categories of factors affecting self-management: Personal/Lifestyle Characteristics; Health Status; Resources; Environmental Characteristics; and Health Care System. Factors may interact to affect self-management and may exist on a continuum of positive (facilitator) to negative (barrier). Conclusion Understanding factors that influence self-management may improve assessment of self-management among adults with chronic illness and may inform interventions tailored to meet individuals’ needs and improve health outcomes.

Inadequate self-management of chronic medical conditions like Type 2 diabetes may play a role in the poor health status of individuals with serious mental illnesses. We compared adherence to hypoglycemic medications and blood glucose control between 44 diabetes patients with a serious mental illness and 30 patients without a psychiatric illness. The two groups did not differ in their ability to manage a complex medication regimen as assessed by a performance-based measure of medication management capacity. However, significantly fewer patients with a mental illness self-reported nonadherence to their hypoglycemic regimens compared to those without a mental illness. Although individuals with mental illnesses also had better control of blood glucose, this metabolic parameter was not correlated with adherence to hypoglycemic medications in either patient group. The experience of managing a chronic mental illness may confer advantages to individuals with serious mental illnesses in the self-care of co-occurring medical conditions like Type 2 diabetes.

2018-01-01

Continuous assessment of respiratory status is one of the cornerstones of modern intensive care unit (ICU) monitoring systems. Electrical impedance tomography (EIT), although with some constraints, may play the lead as a new diagnostic and guiding tool for an adequate optimization of mechanical ventilation in critically ill patients. EIT may assist in defining mechanical ventilation settings, assess distribution of tidal volume and of end-expiratory lung volume (EELV) and contribute to titrate positive end-expiratory pressure (PEEP)/tidal volume combinations. It may also quantify gains (recruitment) and losses (overdistention or derecruitment), granting a more realistic evaluation of different ventilator modes or recruitment maneuvers, and helping in the identification of responders and non-responders to such maneuvers. Moreover, EIT also contributes to the management of life-threatening lung diseases such as pneumothorax, and aids in guiding fluid management in the critical care setting. Lastly, assessment of cardiac function and lung perfusion through electrical impedance is on the way. PMID:29430443

Acute Illness Protocol for Maple Syrup Urine Disease.

Rodan, Lance H; Aldubayan, Saud H; Berry, Gerard T; Levy, Harvey L

2018-01-01

Inborn errors of metabolism (IEMs) are genetic disorders that disrupt enzyme activity, cellular transport, or energy production. They are individually rare but collectively have an incidence of 1:1000. Most patients with IEMs are followed up by a physician with expertise in biochemical genetics (metabolism), but may present outside this setting. Because IEMs can present acutely with life-threatening crises that require specific interventions, it is critical for the emergency medicine physician, pediatrician, internist, and critical care physician as well as the biochemical geneticist to have information on the initial assessment and management of patients with these disorders. Appropriate early care can be lifesaving. This protocol is not designed to replace the expert consultation of a biochemical geneticist, but rather to improve early care and increase the level of comfort of the acute care physician with initial management of maple syrup urine disease until specialty consultation is obtained.

Data warehousing in disease management programs.

Ramick, D C

2001-01-01

Disease management programs offer the benefits of lower disease occurrence, improved patient care, and lower healthcare costs. In such programs, the key mechanism used to identify individuals at risk for targeted diseases is the data warehouse. This article surveys recent warehousing techniques from HMOs to map out critical issues relating to the preparation, design, and implementation of a successful data warehouse. Discussions of scope, data cleansing, and storage management are included in depicting warehouse preparation and design; data implementation options are contrasted. Examples are provided of data warehouse execution in disease management programs that identify members with preexisting illnesses, as well as those exhibiting high-risk conditions. The proper deployment of successful data warehouses in disease management programs benefits both the organization and the member. Organizations benefit from decreased medical costs; members benefit through an improved quality of life through disease-specific care.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is an unexplained incapacitating illness that may affect up to 4 million people in the United States alone. There are no validated laboratory tests for diagnosis or management despite global efforts to find biomarkers of disease. We considered the possibility that inability to identify such biomarkers reflected variations in diagnostic criteria and laboratory methods as well as the timing of sample collection during the course of the illness. Accordingly, we leveraged two large, multicenter cohort studies of ME/CFS to assess the relationship of immune signatures with diagnosis, illness duration, and other clinical variables. Controls were frequency-matched on key variables known to affect immune status, including season of sampling and geographic site, in addition to age and sex. We report here distinct alterations in plasma immune signatures early in the course of ME/CFS ( n = 52) relative to healthy controls ( n = 348) that are not present in subjects with longer duration of illness ( n = 246). Analyses based on disease duration revealed that early ME/CFS cases had a prominent activation of both pro- and anti-inflammatory cytokines as well as dissociation of intercytokine regulatory networks. We found a stronger correlation of cytokine alterations with illness duration than with measures of illness severity, suggesting that the immunopathology of ME/CFS is not static. These findings have critical implications for discovery of interventional strategies and early diagnosis of ME/CFS.

Stehle, Peter; Kuhn, Katharina S

2015-01-01

Critical illness is characterized by glutamine depletion owing to increased metabolic demand. Glutamine is essential to maintain intestinal integrity and function, sustain immunologic response, and maintain antioxidative balance. Insufficient endogenous availability of glutamine may impair outcome in critically ill patients. Consequently, glutamine has been considered to be a conditionally essential amino acid and a necessary component to complete any parenteral nutrition regimen. Recently, this scientifically sound recommendation has been questioned, primarily based on controversial findings from a large multicentre study published in 2013 that evoked considerable uncertainty among clinicians. The present review was conceived to clarify the most important questions surrounding glutamine supplementation in critical care. This was achieved by addressing the role of glutamine in the pathophysiology of critical illness, summarizing recent clinical studies in patients receiving parenteral nutrition with intravenous glutamine, and describing practical concepts for providing parenteral glutamine in critical care.

Fever is a nonspecific response to various types of infectious or non-infectious insult and its significance in disease remains an enigma. Our aim was to summarize the current evidence for the use of antipyretic therapy in critically ill patients. We performed systematic review and meta-analysis of publications from 1966 to 2013. The MEDLINE and CENTRAL databases were searched for studies on antipyresis in critically ill patients. The meta-analysis was limited to: randomized controlled trials; adult human critically ill patients; treatment with antipyretics in one arm versus placebo or non-treatment in another arm; and report of mortality data. The outcomes assessed were overall intensive care unit mortality, changes in temperature, intensive care unit length of stay, and hospital length of stay. Three randomized controlled trials, covering 320 participants, were included. Patients treated with antipyretic agents showed similar intensive care unit mortality (risk ratio 0.91, with 95% confidence interval 0.65-1.28) when compared with controls. The only difference observed was a greater decrease in temperature after 24 hours in patients treated with antipyretics (-1.70±0.40 versus - 0.56±0.25ºC; p=0.014). There is no difference in treating or not the fever in critically ill patients. PMID:25628209

Critical care service is expensive and the demand for such service is increasing in many developed countries. This study aimed to assess the changes in characteristics of critically ill patients and their effect on long-term outcome. This cohort study utilised linked data between the intensive care unit database and state-wide morbidity and mortality databases. Logistic and Cox regression was used to examine hospital survival and five-year survival of 22,298 intensive care unit patients, respectively. There was a significant increase in age, severity of illness and Charlson Comorbidity Index of the patients over a 16-year study period. Although hospital mortality and median length of intensive care unit and hospital stay remained unchanged, one- and five-year survival had significantly improved with time, after adjusting for age, gender; severity of illness, organ failure, comorbidity, 'new' cancer and diagnostic group. Stratified analyses showed that the improvement in five-year survival was particularly strong among patients admitted after cardiac surgery (P = 0.001). In conclusion, although critical care service is increasingly being provided to patients with a higher severity of acute and chronic illnesses, long-term survival outcome has improved with time suggesting that critical care service may still be cost-effectiveness despite the changes in case-mix.

Glutamine Randomized Studies in Early Life: The Unsolved Riddle of Experimental and Clinical Studies

2012-01-01

Glutamine may have benefits during immaturity or critical illness in early life but its effects on outcome end hardpoints are controversial. Our aim was to review randomized studies on glutamine supplementation in pups, infants, and children examining whether glutamine affects outcome. Experimental work has proposed various mechanisms of glutamine action but none of the randomized studies in early life showed any effect on mortality and only a few showed some effect on inflammatory response, organ function, and a trend for infection control. Although apparently safe in animal models (pups), premature infants, and critically ill children, glutamine supplementation does not reduce mortality or late onset sepsis, and its routine use cannot be recommended in these sensitive populations. Large prospectively stratified trials are needed to better define the crucial interrelations of “glutamine-heat shock proteins-stress response” in critical illness and to identify the specific subgroups of premature neonates and critically ill infants or children who may have a greater need for glutamine and who may eventually benefit from its supplementation. The methodological problems noted in the reviewed randomized experimental and clinical trials should be seriously considered in any future well-designed large blinded randomized controlled trial involving glutamine supplementation in critical illness.

Treatment of hypophosphatemia in the intensive care unit: a review

PubMed Central

2010-01-01

Introduction Currently no evidence-based guideline exists for the approach to hypophosphatemia in critically ill patients. Methods We performed a narrative review of the medical literature to identify the incidence, symptoms, and treatment of hypophosphatemia in critically ill patients. Specifically, we searched for answers to the questions whether correction of hypophosphatemia is associated with improved outcome, and whether a certain treatment strategy is superior. Results Incidence: hypophosphatemia is frequently encountered in the intensive care unit; and critically ill patients are at increased risk for developing hypophosphatemia due to the presence of multiple causal factors. Symptoms: hypophosphatemia may lead to a multitude of symptoms, including cardiac and respiratory failure. Treatment: hypophosphatemia is generally corrected when it is symptomatic or severe. However, although multiple studies confirm the efficacy and safety of intravenous phosphate administration, it remains uncertain when and how to correct hypophosphatemia. Outcome: in some studies, hypophosphatemia was associated with higher mortality; a paucity of randomized controlled evidence exists for whether correction of hypophosphatemia improves the outcome in critically ill patients. Conclusions Additional studies addressing the current approach to hypophosphatemia in critically ill patients are required. Studies should focus on the association between hypophosphatemia and morbidity and/or mortality, as well as the effect of correction of this electrolyte disorder. PMID:20682049

Concise Review: Mesenchymal Stem (Stromal) Cells: Biology and Preclinical Evidence for Therapeutic Potential for Organ Dysfunction Following Trauma or Sepsis.

Several experimental studies have provided evidence that bone-marrow derived mesenchymal stem (stromal) cells (MSC) may be effective in treating critically ill surgical patients who develop traumatic brain injury, acute renal failure, or the acute respiratory distress syndrome. There is also preclinical evidence that MSC may be effective in treating sepsis-induced organ failure, including evidence that MSC have antimicrobial properties. This review considers preclinical studies with direct relevance to organ failure following trauma, sepsis or major infections that apply to critically ill patients. Progress has been made in understanding the mechanisms of benefit, including MSC release of paracrine factors, transfer of mitochondria, and elaboration of exosomes and microvesicles. Regardless of how well they are designed, preclinical studies have limitations in modeling the complexity of clinical syndromes, especially in patients who are critically ill. In order to facilitate translation of the preclinical studies of MSC to critically ill patients, there will need to be more standardization regarding MSC production with a focus on culture methods and cell characterization. Finally, well designed clinical trials will be needed in critically ill patient to assess safety and efficacy. Stem Cells 2017;35:316-324. © 2016 AlphaMed Press.

Effect of calcitriol on in vitro whole blood cytokine production in critically ill dogs.

Hypovitaminosis D has been identified as a predictor of mortality in human beings, dogs, cats and foals. However, the immunomodulatory effects of vitamin D in critically ill dogs has not been evaluated. The aim of this study was to evaluate the effect of calcitriol on cytokine production from whole blood collected from critically ill dogs in vitro. Twelve critically ill dogs admitted to a veterinary intensive care unit (ICU) were enrolled in a prospective cohort study. Whole blood from these dogs was incubated with calcitriol (2×10 -7 M) or ethanol (control) for 24h. Subsequent to this incubation, lipopolysaccharide (LPS)-stimulated whole blood production of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 were measured using a canine-specific multiplex assay. Calcitriol significantly increased LPS-stimulated whole blood production of IL-10 and decreased TNF-α production without significantly altering IL-6 production. There was no significant difference in whole blood cytokine production capacity between survivors and non-survivors at the time of discharge from the ICU or 30days after discharge. These data suggests that calcitriol induces an anti-inflammatory phenotype in vitro in whole blood from critically ill dogs. Copyright © 2018 Elsevier Ltd. All rights reserved.

Sepsis is a leading healthcare problem, accounting for the vast majority of fatal events in critically ill patients. Beyond early diagnosis and appropriate treatment, this condition requires a multifaceted approach for monitoring the severity, the potential organ failure as well as the risk of death. Monitoring of the efficacy of treatment is also a major issue in the emergency department (ED). The assessment of critically ill conditions and the prognosis of patients with sepsis is currently based on some scoring systems, which are, however, inefficient to provide definite clues about organ failure and prognosis in general. The discretionary and appropriate use of some selected biomarkers such as procalcitonin, inducible protein 10 (IP10), Group IV phospholipase A2 type II (PLA2 II), neutrophil gelatinase-associated lipocalin (NGAL), natriuretic peptides, mature adrenomedullin (ADM), mid-regional pro-adrenomedullin (MR-proADM), copeptin, thrombopoietin, Mer receptor and even red blood cell distribution width (RDW) represent thereby an appealing perspective in the diagnosis and management of patients with sepsis. Nevertheless, at the moment, it is not still clear if it is better to use a multimarkers approach or if a single, most appropriate, biomarker exists. This collective opinion paper is aimed at providing an overview about the potential clinical usefulness of some innovative biomarkers of sepsis in its diagnosis and prognosis, but also in the treatment management of the disease.

Aggressive glycemic management in critically ill patients with acute burn injury or life-threatening soft-tissue infections has not been thoroughly evaluated. An intensive insulin protocol with target glucose values of less than 120 mg/dl was implemented in October 2005 in our regional Burn-Trauma intensive care unit. We reviewed our initial experience with this protocol to evaluate the safety and efficacy of aggressive glycemic control in these patient groups. Patients were placed on the intensive insulin protocol based upon the need for glycemic management during their hospitalization for burn or soft-tissue disease. Patient information prospectively collected while on protocol included all measured blood glucose values, total daily insulin use, and incidence of hypoglycemic episodes, defined as serum glucose <60 mg/dl. Thirty patients (17 burns, 13 soft-tissue infections) were placed on the intensive insulin protocol during the first 16 months of use. The mean daily blood glucose level for burn patients was 115.9 mg/dl and for soft-tissue disease patients was 119.5 mg/dl. There was a 5% incidence of hypoglycemic episodes per protocol day. All hypoglycemic episodes were treated by holding the insulin infusion, and no episode had known adverse effects. Hyperglycemia in critically ill patients with burns and extensive soft-tissue disease can be effectively managed with an insulin protocol that targets blood glucose values of less than 120 mg/dl with minimal incidence of hypoglycemia. A multicenter prospective randomized trial would provide the ideal forum for evaluating clinical outcome benefits of using an intensive insulin protocol.

Palliative care (PC), introduced early in the management of chronic illness, improves patient outcomes. Early integration of a palliative approach for persons with HIV has been documented to be effective in identifying and managing patient-level concerns over the past decade in African settings. The experience of implementing PC in multiple African and other resource-constrained settings (RCSs) emphasizes the need for essential palliative competencies that can be integrated with chronic disease management for patients and their families facing life-limiting illness. This article is an historical description of how basic palliative competencies were observed to be acceptable for health workers providing outpatient HIV care and treatment during eight years of U.S. implementation of "care and support," a term coined to represent PC for persons living with HIV in RCS. The need for team building and interprofessional education is highlighted. The model is currently being tested in one U.S. city and may represent a mechanism for expanding the palliative approach into management of chronic disease. Such competencies may play a role in the development of the patient-centered medical home, a critical component of U.S. health care reform.

Depressed left ventricular performance. Response to volume infusion in patients with sepsis and septic shock

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ognibene, F.P.; Parker, M.M.; Natanson, C.

Volume infusion, to increase preload and to enhance ventricular performance, is accepted as initial management of septic shock. Recent evidence has demonstrated depressed myocardial function in human septic shock. We analyzed left ventricular performance during volume infusion using serial data from simultaneously obtained pulmonary artery catheter hemodynamic measurements and radionuclide cineangiography. Critically ill control subjects (n = 14), patients with sepsis but without shock (n = 21), and patients with septic shock (n = 21) had prevolume infusion hemodynamic measurements determined and received statistically similar volumes of fluid resulting in similar increases in pulmonary capillary wedge pressure. There was amore » strong trend (p = 0.004) toward less of a change in left ventricular stroke work index (LVSWI) after volume infusion in patients with sepsis and septic shock compared with control subjects. The LVSWI response after volume infusion was significantly less in patients with septic shock when compared with critically ill control subjects (p less than 0.05). These data demonstrate significantly altered ventricular performance, as measured by LVSWI, in response to volume infusion in patients with septic shock.« less

Optimising drug dosing in patients receiving extracorporeal membrane oxygenation.

Optimal pharmacological management during extracorporeal membrane oxygenation (ECMO) involves more than administering drugs to reverse underlying disease. ECMO is a complex therapy that should be administered in a goal-directed manner to achieve therapeutic endpoints that allow reversal of disease and ECMO wean, minimisation of complications (treatment of complications when they do occur), early interruption of sedation and rehabilitation, maximising patient comfort and minimising risks of delirium. ECMO can alter both the pharmacokinetics (PK) and pharmacodynamics (PD) of administered drugs and our understanding of these alterations is still evolving. Based on available data it appears that modern ECMO circuitry probably has a less significant impact on PK when compared with critical illness itself. However, these findings need further confirmation in clinical population PK studies and such studies are underway. The altered PD associated with ECMO is less understood and more research is indicated. Until robust dosing guidelines become available, clinicians will have to rely on the principles of drug dosing in critically ill and known PK alterations induced by ECMO itself. This article summarises the PK alterations and makes preliminary recommendations on possible dosing approaches.

Kidneys play an important role to maintain human homeostasis. They contribute to maintain body fluid, electrolytes, and acid-base balance. Especially in fluid control, we, physicians can intervene body fluid balance using fluid resuscitation and diuretics. In recent years, one type of fluid resuscitation, hydroxyl ethyl starch has been extensively studied in the field of intensive care. Although their effects on fluid resuscitation are reasonable, serious complications such as kidney injury requiring renal replacement therapy occur frequently. Now we have to pay more attention to this important complication. Another topic of fluid management is tolvaptan, a selective vasopressin-2 receptor antagonist Recent randomized trial suggested that tolvaptan has a similar supportive effect for fluid control and more cost effective compared to carperitide. In recent years, Stewart approach is recognized as one important tool to assess acid-base balance in critically ill patients. This approach has great value, especially to understand metabolic components in acid-base balance. Even for assessing the effects of kidneys on acid-base balance, this approach gives us interesting insight. We should appropriately use this new approach to treat acid-base abnormality in critically ill patients.

A total of 278 patients were admitted in the 17 participating ICUs. Median age was 58 years and 70% had newly diagnosed leukemia. ICU mortality rate was 28.6 and 39.6% of the patients alive at 1 year. Admission for intensive monitoring was independently associated with better 1-year survival by multivariate analysis. Conversely, relapsed/refractory disease, secondary leukemia, mechanical ventilation and renal replacement therapy were independently associated with 1-year mortality. This study confirms the impact of organ dysfunction on long-term survival in ICU patients with AL. Follow-up studies to assess respiratory and renal recovery are warranted.

Critical care use during the course of serious illness.

Despite its expense and importance, it is unknown how common critical care use is. We describe longitudinal patterns of critical care use among a nationally representative cohort of elderly patients monitored from the onset of common serious illnesses. A retrospective population-based cohort study of elderly patients in fee-for-service Medicare is used, with 1,108,060 Medicare beneficiaries at least 68 years of age and newly diagnosed with serious illnesses: 1 of 9 malignancies, stroke, congestive heart failure, hip fracture, or myocardial infarction. Medicare inpatient hospital claims from diagnosis until death (65.1%) or fixed-right censoring (more than 4 years) were reviewed. Distinct hospitalizations involving critical care use (intensive care unit or critical care unit) were counted and associated reimbursements were assessed; repeated use was defined as five or more such hospitalizations. Of the cohort, 54.9% used critical care at some time after diagnosis. Older patients were much less likely to ever use critical care (odds ratio, 0.31; comparing patients more than 90 years old with those 68-70 years old), even after adjustment. A total of 31,348 patients (2.8%) were repeated users of critical care; they accounted for 3.6 billion dollars in hospital charges and 1.4 billion dollars in Medicare reimbursement. We conclude that critical care use is common in serious chronic illness and is not associated solely with preterminal hospitalizations. Use is uneven, and a minority of patients who repeatedly use critical care account for disproportionate costs.

Interprofessional collaboration in health has become essential to providing high-quality care, decreased costs, and improved outcomes. Patient-centered care requires synthesis of all the components of primary and specialty medicine to address patient needs. For individuals living with chronic diseases, this model is even more critical to obtain better health outcomes. Studies have shown shown that oral health and systemic disease are correlated as it relates to disease development and progression. Thus, inclusion of oral health in many of the existing and new collaborative models could result in better management of chronic illnesses and improve overall health outcomes.

Matthias, Marianne S.; Fukui, Sadaaki; Salyers, Michelle P.

2016-01-01

Understanding consumer initiation of shared decision making (SDM) is critical to improving SDM in mental health consultations, particularly because providers do not always invite consumer participation in treatment decisions. This study examined the association between consumer initiation of nine elements of SDM as measured by the SDM scale, and measures of consumer illness self-management and the consumer-provider relationship. In 63 mental health visits, three SDM elements were associated with self-management or relationship factors: discussion of consumer goals, treatment alternatives, and pros and cons of a decision. Limitations, implications, and future directions are discussed. PMID:26427999

Fluid management during continuous renal replacement therapy (CRRT) in critically ill patients is a dynamic process that encompasses 3 inter-related goals: maintenance of the patency of the CRRT circuit, maintenance of plasma electrolyte and acid-base homeostasis and regulation of patient fluid balance. In this article, we report the consensus recommendations of the 2016 Acute Disease Quality Initiative XVII conference on 'Precision Fluid Management in CRRT'. We discuss the principles of fluid management, describe various prescription methods to achieve circuit integrity and introduce the concept of integrated fluid balance for tailoring fluid balance to the needs of the individual patient. We suggest that these recommendations could serve to develop the best clinical practice and standards of care for fluid management in patients undergoing CRRT. Finally, we identify and highlight areas of uncertainty in fluid management and set an agenda for future research. © 2016 S. Karger AG, Basel.

Pulmonary infections in critical/intensive care - rapid diagnosis and optimizing antimicrobial usage.

PubMed

Douglas, Ivor S

2017-05-01

Diagnosis of pulmonary infection, including hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) in the critically ill patient remains a common and therapeutically challenging diagnosis with significant attributable morbidity, mortality, and cost. Current clinical approaches to surveillance, early detection and, conventional culture-based microbiology are inadequate for optimal targeted antibiotic treatment and stewardship. Efforts to enhance diagnosis of HAP and VAP and the impact of these novel approaches on rational antimicrobial selection and stewardship are the focus of recent studies reviewed here. Recent consensus guidelines for diagnosis and management of HAP and VAP are relatively silent on the potential role of novel rapid microbiological techniques and reply heavily on conventional culture strategies of noninvasively obtained (including endotracheal aspirate samples). Novel rapid microbiological diagnostics, including nucleic acid amplification, mass spectrometry, and fluorescence microscopy-based technologies are promising approaches for the future. Exhaled breath biomarkers, including measurement of VOC represent a future approach. Further validation of novel diagnostic technology platforms will be required to evaluate their utility for enhancing diagnosis and guiding treatment of pulmonary infections in the critically ill. However, the integration of novel diagnostics for rapid microbial identification, resistance phenotyping, and antibiotic sensitivity testing into usual care practice could significantly transform the care of patients and potentially inform improved targeted antimicrobial selection, de-escalation, and stewardship.

The use of negative pressure in critical necrotizing fasciitis treatment: a case presentation.

Surgery complemented by antibiotics forms the backbone of the successful management of necrotizing fasciitis. But it will be very difficult to clear away extensive necrotizing tissue thoroughly in critically ill patients when their vital signs are unstable. The authors report the case of a 33-year-old woman who had extensive necrotizing fasciitis of the right lower limb with septic shock. The patient was severely anemic and malnutrition and had been given conservative debridement at bedside, that is, only detached necrotizing tissues was taken away while some other necrotizing tissue still remained, so that the skin tissue within the same area could be saved as much as possible. After debridement, negative pressure was applied at 125 mm Hg. Broad-spectrum antibiotics and effective supplementation were also complemented, thus controlling the septic shock. All necrotizing tissues were detached, and the sparing vital skin on necrotizing fascia was preserved successfully after negative pressure treatment. The patient was finally saved. In conclusion, negative pressure treatment may help diminish toxin absorbance, detach gangrene tissue, and preserve sparing vital tissue. This case suggests the value of combined use of negative pressure therapy and conservative debridement in critically ill patients with extensive necrotizing fasciitis. © The Author(s) 2014.

To evaluate the prevalence of a difference in systolic blood pressure (SBPd) ≥ 10 mmHg between arms in patients admitted in a Critical Care Unit and to examine the clinical characteristics associated with such blood pressure difference. Observational cross-sectional study. Two blood pressure measurements in each arm were carried out at unit admission. The firstly measured arm was chosen at random. One-hundred and sixty-eight patients were studied, with a mean age of 61 (SD=16), 67.3% male and 45% with a previous hypertension diagnosis. On admission, 27.4% presented SBPd ≥ 10 mmHg. Among them, 54% had higher SBP in the right arm and 46% in the left one. A SBPd ≥ 10 mmHg was associated with a previous hypertension diagnosis (67.4 versus 36.9%; P<.001) and with reduced consciousness (76.1 versus 52.5%; P=.006). Over a quarter of critically ill patients have a SBPd ≥ 10 mmHg between arms. This feature is associated with a previous hypertension diagnosis and reduced consciousness. It should be assessed in the future if the choice of a control arm would help improve patient's care as it would become a more accurate guide for hemodynamic management.

Nurses have an important role in the delivery and management of enteral nutrition in critically ill patients, to prevent iatrogenic malnutrition. It is not clear how nurses source enteral nutrition information. This study aimed to explore Australian nurses' enteral nutrition knowledge and sources of information. Data were collected from members of the Australian College of Critical Care Nurses in May 2014 using an online questionnaire. A combination of descriptive statistics and non-parametric analyses were undertaken to evaluate quantitative data. Content analysis was used to evaluate qualitative data. 359 responses were included in data analysis. All respondents were Registered Nurses with experience working in an Australian intensive care unit or high dependency unit. Most respondents reported their enteral nutrition knowledge was good (n=205, 60.1%) or excellent (n=35, 10.3%), but many lacked knowledge regarding the effect of malnutrition on patient outcomes. Dietitians and hospital protocols were the most valuable sources of enteral nutrition information, but were not consistently utilised. Significant knowledge deficits in relation to enteral nutrition were identified. Dietitians were the preferred source of nurses' enteral nutrition information, however their limited availability impacted their efficacy as an information resource. Educational opportunities for nurses need to be improved to enable appropriate nutritional care in critically ill patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

Background Advice on fibromyalgia, a chronic illness primarily affecting women, often presents it as incompatible with work and rarely covers how to remain employed. Yet many women do. Objectives We aimed to understand how these women, their family members, and workmates portrayed employees with fibromyalgia, and how these portrayals helped women retain employment. Methods We interviewed 22 participants, comprising five triads and three dyads of people who knew each other. Using the methodology of critical discourse analysis, we analysed the interview data within and across the triads/dyads through coding, narrative summaries, and relational mapping. Results Participants reported stereotypes that employees with fibromyalgia are lazy, malingering, and less productive than healthy workers. Countering these assumptions, participants portrayed the women as normal, valuable employees who did not 'give in' to their illness. The portrayals drew on two discourses, normalcy and mind-controlling-the-body, and a related narrative, overcoming disability. We propose that participants' portrayals helped women manage their identities in competitive workplaces and thereby remain employed. Discussion Our findings augment the very sparse literature on employment with fibromyalgia. Using a new approach, critical discourse analysis, we expand on known job-retention strategies and add the perspectives of two key stakeholders: family members and workmates.

Suicide risk of your client: initial identification and management for the allied health professional.

Donley, Euan

2013-01-01

Allied health professionals treat clients in varying degrees of distress with complex needs in a wide range of services. A client could be experiencing a chronic or life-changing illness, have a trauma from a critical event, have preexisting mental illness, be dealing with significant health or personal loss, be using substances, or experiencing a depression. At some point an allied health professional will treat a client who may have a diagnosed depression, appear depressed, or have thoughts of suicide. Mental health of clients is everyone's responsibility, especially those working in health. This article aims to increase allied health professionals' understanding of some risk factors and clinical features a client at risk may have and will discuss some initial options of management. It is recommended the allied health professional and organisation be aware of risk factors for suicide but not rely too heavily on risk screening. The worker should have basic skills in recognising poor mood and have a list of useful questions to ask in a crisis. Know your local crisis and supportive mental health services, create links with them, have ongoing professional education and protocols for managing clients at-risk, and be acutely aware of your role and limitations.

Treatment Nonadherence in Inflammatory Bowel Disease: Identification, Scope, and Management Strategies.

Herman, Margot L; Kane, Sunanda V

2015-12-01

Treatment adherence is of critical importance in the management of patients with IBD. Poor adherence can lead to increased disease activity, loss of response to therapy, and increased costs of care. It has been well established that adherence to long-term therapy for chronic illnesses is extremely poor, averaging around 50% in developed countries. Measured rates of nonadherence in IBD are similar, but vary depending on the type of therapy and the population being observed. This article reviews the scientific data on treatment nonadherence in IBD. The methods commonly used to evaluate treatment adherence investigation are reviewed. The consequences and scope of treatment nonadherence are summarized. Finally, the scientific data on management strategies to address the problem of treatment nonadherence are explored.

Civilizing the 'Barbarian': a critical analysis of behaviour modification programmes in forensic psychiatry settings.

PubMed

Holmes, Dave; Murray, Stuart J

2011-04-01

Drawing on the works of Erving Goffman and Michel Foucault, this article presents part of the results of a qualitative study conducted in a forensic psychiatry setting. For many years, behaviour modification programmes (BMPs) have been subjected to scrutiny and harsh criticism on the part of researchers, clinicians and professional organizations. Nevertheless, BMPs continue to be in vogue in some 'total' institutions, such as psychiatric hospitals and prisons. Discourse analysis of mute evidence available in situ was used to critically look at behaviour modification programmes. Compelling examples of behaviour modification care plans are used to illustrate our critical analysis and to support our claim that BMPs violate both scientific and ethical norms in the name of doing 'what is best' for the patients. We argue that the continued use of BMPs is not only flawed from a scientific perspective, but constitutes an unethical approach to the management of nursing care for mentally ill offenders. Nurse managers need to be aware that BMPs violate ethical standards in nursing. As a consequence, they should overtly question the use of these approaches in psychiatric nursing. © 2011 The Authors.

Demand for critical care services is increasing. Unless the supply of intensivists increases, critically ill patients will not have access to intensivists. Recent critical care society recommendations include increased graduate medical education support and expansion of the J-1 visa waiver program for foreign medical graduates. This article proposes additional recommendations, based on strengthening the relationship between emergency medicine and critical care medicine. Demand for critical care services is increasing. Unless the supply of intensivists increases, critically ill patients will not have access to intensivists. Recent critical care society recommendations include increased graduate medical education support and expansion of the J-1 visa waiver program for foreign medical graduates. This article proposes additional recommendations, based on strengthening the relationship between emergency medicine (EM) and critical care medicine (CCM). Critical care is a continuum that includes prehospital, emergency department (ED), and intensive care unit (ICU) care teams. Both EM and CCM require expertise in treating life-threatening acute illness, with many critically ill patients often presenting first to the ED. Increased patient volumes and acuity have resulted in longer ED lengths of stay and more critical care delivery in the ED. However, the majority of CCM fellowships do not accept EM residents, and those who successfully complete a fellowship do not have access to a U.S. certification exam in CCM. Despite these barriers, interest in CCM training among EM physicians is increasing. Dual EM/CCM-trained physicians not only will help alleviate the intensivist shortage but also will strengthen critical care delivery in the ED and facilitate coordination at the ED-ICU interface. We therefore propose that all accreditation bodies work cooperatively to create a route to CCM certification for emergency physicians who complete a critical care fellowship.

Therapeutic hypothermia and pressure ulcer risk in critically ill intensive care patients: A retrospective study.

To examine the role of therapeutic hypothermia in pressure ulcer development in critically ill patients. Retrospective study in a mixed intensive care unit over 2010-2013. The incidences of pressure ulcers among patients treated with therapeutic hypothermia (n = 148) and the non-hypothermia patient population (n = 6197) were compared. Patients treated with hypothermia developed more pressure ulcers (25.0%) than the non-hypothermia group 6.3% (p < 0.001). More patients in the hypothermia group were rated as the high pressure ulcer risk group, as defined by the modified Jackson/Cubbin (mJ/C) risk score ≤29 than the rest of the patients. Among the therapeutic hypothermia patients more pressure ulcers tended to emerge in the lower risk group (mJ/C score ≥30) (p = 0.056). Intensive care mortality was higher in the hypothermia (24.3%) than the non-hypothermia group (9.3%, p < 0.0001). Patients treated with therapeutic hypothermia should be considered at high risk for pressure ulcer development and should be managed accordingly. The hypothermia may not as such increase the risk for pressure ulcers, but combined with the severity of the underlying illness, may be more likely. The pressure ulcer risk in this patient group cannot be reliably assessed by the Jackson/Cubbin risk scale. Copyright © 2018 Elsevier Ltd. All rights reserved.

Despite poor outcomes, life-sustaining treatments including mechanical ventilation are continued for a large and growing population of patients with chronic critical illness. This may be owing in part to a lack of understanding resulting from inadequate communication between clinicians and patients and families. Our objective was to investigate the informational needs of patients with chronic critical illness and their families and the extent to which these needs are met. In this prospective observational study conducted at 5 adult intensive care units in a large, university-affiliated hospital in New York, New York, 100 patients with chronic critical illness (within 3-7 days of elective tracheotomy for prolonged mechanical ventilation) or surrogates for incapacitated patients were surveyed using an 18-item questionnaire addressing communication about chronic critical illness. Main outcome measures included ratings of importance and reports of whether information was received about questionnaire items. Among 125 consecutive, eligible patients, 100 (80%) were enrolled; questionnaire respondents included 2 patients and 98 surrogates. For all items, more than 78% of respondents rated the information as important for decision making (>98% for 16 of 18 items). Respondents reported receiving no information for a mean (SD) of 9.0 (3.3) of 18 items, with 95% of respondents reporting not receiving information for approximately one-quarter of the items. Of the subjects rating the item as important, 77 of 96 (80%) and 69 of 74 (93%) reported receiving no information about expected functional status at hospital discharge and prognosis for 1-year survival, respectively. Many patients and their families may lack important information for decision making about continuation of treatment in the chronic phase of critical illness. Strategies for effective communication in this clinical context should be investigated and implemented.

To determine how patient, healthcare system and study-specific factors influence reported mortality associated with critical illness during the 2009-2010 Influenza A (H1N1) pandemic. Systematic review with meta-regression of studies reporting on mortality associated with critical illness during the 2009-2010 Influenza A (H1N1) pandemic. Medline, Embase, LiLACs and African Index Medicus to June 2009-March 2016. 226 studies from 50 countries met our inclusion criteria. Mortality associated with H1N1-related critical illness was 31% (95% CI 28-34). Reported mortality was highest in South Asia (61% [95% CI 50-71]) and Sub-Saharan Africa (53% [95% CI 29-75]), in comparison to Western Europe (25% [95% CI 22-30]), North America (25% [95% CI 22-27]) and Australia (15% [95% CI 13-18]) (P<0.0001). High income economies had significantly lower reported mortality compared to upper middle income economies and lower middle income economies respectively (P<0.0001). Mortality for the first wave was non-significantly higher than wave two (P = 0.66). There was substantial variability in reported mortality among the specific subgroups of patients: unselected critically ill adults (27% [95% CI 24-30]), acute respiratory distress syndrome (37% [95% CI 32-44]), acute kidney injury (44% [95% CI 26-64]), and critically ill pregnant patients (10% [95% CI 5-19]). Reported mortality for outbreaks and pandemics may vary substantially depending upon selected patient characteristics, the number of patients described, and the region and economic status of the outbreak location. Outcomes from a relatively small number of patients from specific regions may lead to biased estimates of outcomes on a global scale.

Introduction Polyunsaturated series-3 fatty acids (PUFAs n-3) contained in fish oils (FO) posess major anti-inflammatory, anti-oxidant, and immunological properties which could be beneficial during critical illness. We hypothesized that parenteral FO containing emulsions may improve clinical outcomes in the critically ill. Methods We searched computerized databases from 1980 to 2012. We included randomized controlled trials (RCTs) conducted in critically ill adults patients that evaluated FO containing emulsions, either in the context of parenteral nutrition (PN) or enteral nutrition (EN) fed patients. Results A total of 6 RCTs (n=390 patients) were included; the mean methodological score of all trials was 10 (range: 6–13). When the results of these studies were aggregated, FO containing emulsions were associated with with a trend towards a reduction in mortality (risk ratio RR= 0.71, 95% confidence intervals CI 0.49, 1.04, P=0.08, heterogeneity I2=0%) and a tendency to reduce the duration of mechanical ventilation (weighted mean difference in days [WMD] −1.41, 95% CI −3.43, 0.61, P=0.17). However, this strategy had no effect on infections (RR= 0.76, 95% CI 0.42, 1.36, P= 0.35) and intensive care unit (ICU) length of stay (LOS) (WMD −0.46, 95% CI −4.87, 3.95, P=0.84, heterogeneity I2=75%). Conclusion FO containing lipid emulsions may be able to decrease mortality and ventilation days in the critically ill. However, because of the paucity of clinical data, there is inadequate evidence to recommend the routine use of parenteral FO. Large, rigorously designed, RCTs are required to elucidate the efficacy of parenteral FO in the critically ill. PMID:23609773

Optimal antibiotic dosing is key to maximising patient survival, and minimising the emergence of bacterial resistance. Evidence-based antibiotic dosing guidelines for critically ill patients receiving RRT are currently not available, as RRT techniques and settings vary greatly between ICUs and even individual patients. We aim to develop a robust, evidence-based antibiotic dosing guideline for critically ill patients receiving various forms of RRT. We further aim to observe whether therapeutic antibiotic concentrations are associated with reduced 28-day mortality. We designed a multi-national, observational pharmacokinetic study in critically ill patients requiring RRT. The study antibiotics will be vancomycin, linezolid, piperacillin/tazobactam and meropenem. Pharmacokinetic sampling of each patient's blood, RRT effluent and urine will take place during two separate dosing intervals. In addition, a comprehensive data set, which includes the patients' demographic and clinical parameters, as well as modality, technique and settings of RRT, will be collected. Pharmacokinetic data will be analysed using a population pharmacokinetic approach to identify covariates associated with changes in pharmacokinetic parameters in critically ill patients with AKI who are undergoing RRT for the five commonly prescribed antibiotics. Using the comprehensive data set collected, the pharmacokinetic profile of the five antibiotics will be constructed, including identification of RRT and other factors indicative of the need for altered antibiotic dosing requirements. This will enable us to develop a dosing guideline for each individual antibiotic that is likely to be relevant to any critically ill patient with acute kidney injury receiving any of the included forms of RRT.

Commensal microbiota are immunomodulatory, and their pathological perturbation can affect the risk and outcomes of infectious and inflammatory diseases. Consequently, the human microbiota is an emerging diagnostic and therapeutic target in critical illness. In this study, we compared four sample types-rectal, naris, and antecubital swabs and stool samples-for 16S rRNA gene microbiota sequencing in intensive care unit (ICU) patients. Stool samples were obtained in only 31% of daily attempts, while swabs were reliably obtained (≥97% of attempts). Swabs were compositionally distinct by anatomical site, and rectal swabs identified within-patient temporal trends in microbiota composition. Rectal swabs from ICU patients demonstrated differences from healthy stool similar to those observed in comparing stool samples from ICU patients to those from the same healthy controls. Rectal swabs are a useful complement to other sample types for analysis of the intestinal microbiota in critical illness, particularly when obtaining stool may not be feasible or practical. IMPORTANCE Perturbation of the microbiome has been correlated with various infectious and inflammatory diseases and is common in critically ill patients. Stool is typically used to sample the microbiota in human observational studies; however, it is often unavailable for collection from critically ill patients, reducing its utility as a sample type to study this population. Our research identified alternatives to stool for sampling the microbiota during critical illness. Rectal and naris swabs were practical alternatives for use in these patients, as they were observed to be more reliably obtained than stool, were suitable for culture-independent analysis, and successfully captured within- and between-patient microbiota differences.

Background Acute kidney injury (AKI) increases the morbidity of critically ill children. Thus, it is necessary to identify better renal biomarkers to follow the outcome of these patients. This prospective case–control study explored the clinical value of a urinary biomarker profile comprised of neutrophil gelatinase lipocalin (uNGAL), fibroblast growth factor-2 (uFGF-2), and epidermal growth factor (uEGF) to follow these patients. Methods Urine samples were collected from 21 healthy children, and 39 critically ill children (mean age 7.5 years±6.97 SD) admitted to a pediatric intensive care unit with sepsis or requiring extra corporeal membrane oxygenation (ECMO). uNGAL, uFGF-2, and uEGF levels were measured using ELISA kits during the first 24 h of admission to PICU, at peak of illness, and upon resolution of the critical illness. Results On admission, the uNGAL and uFGF-2 levels were increased, and the uEGF levels were decreased, in critically ill children with AKI (n=19) compared to those without AKI (n=20), and healthy controls. A biomarker score using the combined cut-off values of uNGAL, uFGF-2, and uEGF (AUC=0.90) showed the highest specificity to identify children with AKI, relative to each biomarker alone. uNGAL and uFGF-2 on admission showed high sensitivity and specificity to predict mortality (AUC=0.82). Conclusions The biomarker profile comprised of uNGAL, uFGF-2, and uEGF increased the specificity to detect AKI in critically ill children, when compared to each biomarker used alone. uNGAL and uFGF-2 may also predict the risk of death. Further validation of these findings in a large sample size is warranted. PMID:23872928

Receiving power through confirmation: the meaning of close relatives for people who have been critically ill.

PubMed

Engström, Asa; Söderberg, Siv

This paper is a report of a study to elucidate the meaning of close relatives for people who have been critically ill and received care in an intensive care unit. Falling critically ill can bring about a difficult change in life. In previous reports such events are described as frightening experiences, and close relatives are described as an important source of support in this difficult situation. A purposive sample of 10 adults, eight men and two women, narrated how they experienced their close relatives during and after the time they were critically ill. The data were collected in 2004. The interview texts were transcribed and interpreted using a phenomenological hermeneutic approach influenced by the philosophy of Ricoeur. One major theme was identified, experiencing confirmation, with six sub-themes: receiving explanations; a feeling of being understood; a feeling of safety; gaining strength and will-power; having possibilities and realizing their value. Close relatives served as tools for the person who was ill, facilitating better communication and an increased ability to do various things. Simultaneously, feelings of dependence on the close relatives were expressed. There were descriptions of loneliness and fear in the absence of close relatives and, in order to feel safe, the participants wanted their close relatives to stay near them. Close relatives are vital, as they are the ill person's motivation to stay alive and to continue the struggle. Their presence is of great importance for the ill person and must be facilitated by staff.

Seizures and status epilepticus (SE), both clinical and subclinical, are frequent in critically ill patients. The list of available antiseizure medications (ASMs) is expanding and now includes older and widely used drugs as well as more recent medications with a better safety and pharmacokinetics profile. We review a selection of recent publications about the indications and administration of ASMs in critical care for the prophylaxis and treatment of seizures and SE, focusing on recent ASMs available as intravenous formulation and emphasizing pharmacokinetics and safety issues in relation to several aspects of critical illness. Levetiracetam, lacosamide and more recently brivaracetam, represent interesting alternatives to older ASMs, mostly due to a more favorable safety and pharmacokinetic profile. Low-quality studies suggest that this profile results in better tolerability in treated patients. Ketamine might represent a useful addition in our anesthetic armamentarium for refractory SE, due to its different mechanism of action and cardiovascular properties. Little evidence is available however to support the prophylactic use of ASMs in critically ill patients, except in specific settings (traumatic brain injury and subarachnoid hemorrhage). Head-to-head studies comparing recent and older ASMs in the treatment of acute seizures and SE are ongoing or awaiting publication. Administration of ASMs to critically ill patients needs to be adapted to organ dysfunction, and especially to renal dysfunction for recent drugs. Recent ASMs and could represent better treatment choices in critically ill patients than older ones but this needs to be confirmed in randomized controlled studies. In general, further studies are required to clarify the indications and optimal use of ASMs in the critical care setting.

Emergency department (ED) visits for acute alcohol intoxication are common, but this population is at risk for decompensation and occult critical illness. The purpose of this study is to describe the incidence and predictors of unsuspected critical illness among patients with acute alcohol intoxication. This was a retrospective observational study of ED patients from 2011 to 2016 with acute alcohol intoxication. The study cohort included patients presenting for alcohol intoxication, whose initial assessment was uncomplicated alcohol intoxication without any other active acute medical or traumatic complaints. The primary outcome was defined as the unanticipated subsequent use of critical care resources during the encounter or admission to an ICU. We investigated potential predictors for this outcome with generalized estimating equations. We identified 31,364 eligible patient encounters (median age 38 years; 71% men; median breath alcohol concentration 234 mg/dL); 325 encounters (1%) used critical care resources. The most common diagnoses per 1,000 ED encounters were acute hypoxic respiratory failure (3.1), alcohol withdrawal (1.7), sepsis or infection (1.1), and intracranial hemorrhage (1.0). Three patients sustained a cardiac arrest. Presence of the following had an increased adjusted odds ratio (aOR) of developing critical illness: hypoglycemia (aOR 9.2), hypotension (aOR 3.8), tachycardia (aOR 1.8), fever (aOR 7.6), hypoxia (aOR 3.8), hypothermia (aOR 4.2), and parenteral sedation (aOR 2.4). The initial blood alcohol concentration aOR was 1.0. Critical care resources were used for 1% of ED patients with alcohol intoxication who were initially assessed by physicians to have low risk. Abnormal vital signs, hypoglycemia, and chemical sedation were associated with increased odds of critical illness. Copyright © 2017 American College of Emergency Physicians.

Mesenteric ischemia and infarction are infrequent but often deadly conditions in acute and critically ill patients. Mesenteric ischemia may be a primary admission diagnosis or may develop secondary to another diagnosis. Having a high index of suspicion for patients at risk of mesenteric ischemia and mesenteric infarction can alter a poor outcome. This article reviews the pathophysiology, risk factors, assessment, medical and nursing diagnoses, as well as collaborative management for mesenteric ischemia. Early identification of patients at risk and the appropriate diagnostic testing are stressed. Nurses armed with the knowledge of this condition are better able to provide safe care to their patients. ©2018 American Association of Critical-Care Nurses.

Provider competence may affect the impact of a practice. The current study examined this relationship in sixty-three providers engaging in Illness Management and Recovery with 236 consumers. Improving upon previous research, the present study utilized a psychometrically validated competence measure in the ratings of multiple Illness Management and Recovery sessions from community providers, and mapped outcomes onto the theory underlying the practice. Provider competence was positively associated with illness self-management and adaptive coping. Results also indicated baseline self-management skills and working alliance may affect the relationship between competence and outcomes.

Initial adequate anti-infective therapy is associated with significantly improved clinical outcomes for patients with severe infections. However, in critically ill patients, several pathophysiological and/or iatrogenic factors may affect the pharmacokinetics of anti-infective agents leading to suboptimal drug exposure, in particular during the early phase of therapy. Therapeutic drug monitoring (TDM) may assist to overcome this problem. We discuss the available evidence on the use of TDM in critically ill patient populations for a number of anti-infective agents, including aminoglycosides, β-lactams, glycopeptides, antifungals and antivirals. Also, we present the available evidence on the practices of anti-infective TDM and describe the potential utility of TDM to improve treatment outcome in critically ill patients with severe infections. For aminoglycosides, glycopeptides and voriconazole, beneficial effects of TDM have been established on both drug effectiveness and potential side effects. However, for other drugs, therapeutic ranges need to be further defined to optimize treatment prescription in this setting.

Severe malaria caused by Plasmodium vivax is no longer considered rare. To describe its clinical features, we performed a retrospective case control study in the subregion of Luciano Castillo Colonna, Piura, Peru, an area with nearly exclusive vivax malaria transmission. Severe cases and the subset of critically ill cases were compared with a random set of uncomplicated malaria cases (1:4). Between 2008 and 2009, 6,502 malaria cases were reported, including 106 hospitalized cases, 81 of which fit the World Health Organization definition for severe malaria. Of these 81 individuals, 28 individuals were critically ill (0.4%, 95% confidence interval = 0.2–0.6%) with severe anemia (57%), shock (25%), lung injury (21%), acute renal failure (14%), or cerebral malaria (11%). Two potentially malaria-related deaths occurred. Compared with uncomplicated cases, individuals critically ill were older (38 versus 26 years old, P < 0.001), but similar in other regards. Severe vivax malaria monoinfection with critical illness is more common than previously thought. PMID:24752683

Trophic or full nutritional support?

PubMed

Arabi, Yaseen M; Al-Dorzi, Hasan M

2018-06-04

Full nutritional support during the acute phase of critical illness has traditionally been recommended to reduce catabolism and prevent malnutrition. Approaches to achieve full nutrition include early initiation of nutritional support, targeting full nutritional requirement as soon as possible and initiation of supplemental parenteral nutrition when enteral nutrition does not reach the target. Existing evidence supports early enteral nutrition over delayed enteral nutrition or early parenteral nutrition. Recent randomized controlled trials have demonstrated that permissive underfeeding or trophic feeding is associated with similar outcomes compared with full feeding in the acute phase of critical illness. In patients with refeeding syndrome, patients with high nutritional risk and patients with shock, early enteral nutrition targeting full nutritional targets may be associated with worse outcomes compared with less aggressive enteral nutrition strategy. A two-phase approach for nutritional support may more appropriately account for the physiologic changes during critical illness than one-phase approach. Further evidence is awaited for the optimal protein amount during critical illness and for feeding patients at high nutritional risk or with acute gastrointestinal injury.

The Task Force reviewed and discussed the available literature on the effectiveness of physiotherapy for acute and chronic critically ill adult patients. Evidence from randomized controlled trials or meta-analyses was limited and most of the recommendations were level C (evidence from uncontrolled or nonrandomized trials, or from observational studies) and D (expert opinion). However, the following evidence-based targets for physiotherapy were identified: deconditioning, impaired airway clearance, atelectasis, intubation avoidance, and weaning failure. Discrepancies and lack of data on the efficacy of physiotherapy in clinical trials support the need to identify guidelines for physiotherapy assessments, in particular to identify patient characteristics that enable treatments to be prescribed and modified on an individual basis. There is a need to standardize pathways for clinical decision-making and education, to define the professional profile of physiotherapists, and increase the awareness of the benefits of prevention and treatment of immobility and deconditioning for critically ill adult patients.

Recent literature has created considerable confusion about the optimal amount of protein/amino acids that should be provided to the critically ill patient. In fact, the evidentiary basis that directly tries to answer this question is relatively small. As a clinical nutrition research community, there is an urgent need to develop the optimal methods to assess the impact of exogenous protein/amino acid administration in the intensive care unit setting. That assessment can be conducted at various levels: (1) impact on stress response pathways, (2) impact on muscle synthesis and protein balance, (3) impact on muscle mass and function, and (4) impact on the patient's recovery. The objective of this research workshop was to review current literature relating to protein/amino acid administration for the critically ill patient and clinical outcomes and to discuss the key measurement and methodological features of future studies that should be done to inform the optimal protein/amino acid dose provided to critically ill patients.

Evidence to Support Tooth Brushing in Critically Ill Patients

PubMed Central

Ames, Nancy J.

2012-01-01

Tooth brushing in critically ill patients has been advocated by many as a standard of care despite the limited evidence to support this practice. Attention has been focused on oral care as the evidence accumulates to support an association between the bacteria in the oral microbiome and those respiratory pathogens that cause pneumonia. It is plausible to assume that respiratory pathogens originating in the oral cavity are aspirated into the lungs, causing infection. A recent study of the effects of a powered toothbrush on the incidence of ventilator-associated pneumonia was stopped early because of a lack of effect in the treatment group. This review summarizes the evidence that supports the effectiveness of tooth brushing in critically ill adults and children receiving mechanical ventilation. Possible reasons for the lack of benefit of tooth brushing demonstrated in clinical trials are discussed. Recommendations for future trials in critically ill patients are suggested. With increased emphasis being placed on oral care, the evidence that supports this intervention must be evaluated carefully. PMID:21532045

[Critical illness polyneuropathy and myopathy].

PubMed

Motomura, Masakatsu

2003-11-01

Critical Illness Polyneuropathy (CIP) and Myopathy (CIM), either singly or in combination, are a common complication of critical illness. Both disorders may lead to severe weakness and require mechanical ventilation. CIP, as initially described by Bolton et al., in 1984, is a sensorimotor polyneuropathy that is often a complication of sepsis and multiorgan failure. In Japan, Horinouchi et al., first reported a case in 1994. CIM has been referred to by a number of different terms (acute quadriplegic myopathy, thick filament myopathy, acute necrotizing myopathy of intensive care, rapidly evolving myopathy with myosin-deficiency fibers) in the literature. A variety of serious problems (e.g., pneumonia, severe asthma, and lung or liver transplantation) and the concomitant use of high-dose intravenous corticosteroids and nondepolarizing neuromuscular blocking agents predispose to CIM. In Japan, Kawada et al., reported a first case as acute quadriplegic myopathy in 2000. There is no specific treatment for CIP and CIM. Minimizing the use of corticosteroids and nondepolarizing neuromuscular blocking agents in a critical illness setting may prove helpful in preventing the occurrence of these disorders. The prognosis is directly related to the age of the patient and the seriousness of the underlying illness.

Unique Practice, Unique Place: Exploring Two Assertive Community Treatment Teams in Maine.

Assertive Community Treatment (ACT) is a model of care that provides comprehensive community-based psychiatric care for persons with serious mental illness. This model has been widely documented and has shown to be an evidence-based model of care for reducing hospitalizations for this targeted population. Critical ingredients of the ACT model are the holistic nature of their services, a team based approach to treatment and nurses who assist with illness management, medication monitoring, and provider collaboration. Although the model remains strong there are clear differences between urban and rural teams. This article describes present day practice in two disparate ACT programs in urban and rural Maine. It offers a new perspective on the evolving and innovative program of services that treat those with serious mental illness along with a review of literature pertinent to the ACT model and future recommendations for nursing practice. The success and longevity of these two ACT programs are testament to the quality of care and commitment of staff that work with seriously mentally ill consumers. Integrative care models such as these community-based treatment teams and nursing driven interventions are prime elements of this successful model.

Argatroban or lepirudin anticoagulation therapy in patients with heparin induced thrombocytopenia (HIT) or HIT suspect is typically monitored using the activated partial thromboplastin time (aPTT). Although aPTT correlates well with plasma levels of argatroban and lepirudin in healthy volunteers, it might not be the method of choice in critically ill patients. However, in-vivo data is lacking for this patient population. Therefore, we studied in vivo whether ROTEM or global clotting times would provide an alternative for monitoring the anticoagulant intensity effects in critically ill patients. This study was part of the double-blind randomized trial "Argatroban versus Lepirudin in critically ill patients (ALicia)", which compared critically ill patients treated with argatroban or lepirudin. Following institutional review board approval and written informed consent, for this sub-study blood of 35 critically ill patients was analysed. Before as well as 12, 24, 48 and 72 h after initiation of argatroban or lepirudin infusion, blood was analysed for aPTT, aPTT ratios, thrombin time (TT), INTEM CT,INTEM CT ratios, EXTEM CT, EXTEM CT ratios and maximum clot firmness (MCF) and correlated with the corresponding plasma concentrations of the direct thrombin inhibitor. To reach a target aPTT of 1.5 to 2 times baseline, median [IQR] plasma concentrations of 0.35 [0.01-1.2] μg/ml argatroban and 0.17 [0.1-0.32] μg/ml lepirudin were required. For both drugs, there was no significant correlation between aPTT and aPTT ratios and plasma concentrations. INTEM CT, INTEM CT ratios, EXTEM CT, EXTEM CT ratios, TT and TT ratios correlated significantly with plasma concentrations of both drugs. Additionally, agreement between argatroban plasma levels and EXTEM CT and EXTEM CT ratios were superior to agreement between argatroban plasma levels and aPTT in the Bland Altman analysis. MCF remained unchanged during therapy with both drugs. In critically ill patients, TT and ROTEM parameters may provide better correlation to argatroban and lepirudin plasma concentrations than aPTT.

The reference method to study protein and arginine metabolism in critically ill children is measuring plasma amino acid appearances with stable isotopes during a short (4-8 h) time period and extrapolate results to 24-h. However, 24-h measurements may be variable due to critical illness related factors and a circadian rhythm could be present. Since only short duration stable isotope studies in critically ill children have been conducted before, the aim of this study was to investigate 24-h appearance of specific amino acids representing protein and arginine metabolism, with stable isotope techniques in continuously fed critically ill children. In eight critically ill children, admitted to the pediatric (n = 4) or cardiovascular (n = 4) intensive care unit, aged 0-10 years, receiving continuous (par)enteral nutrition with protein intake 1.0-3.7 g/kg/day, a 24-h stable isotope tracer protocol was carried out. L-[ring- 2 H 5 ]-phenylalanine, L-[3,3- 2 H 2 ]-tyrosine, L-[5,5,5- 2 H 3 ]-leucine, L-[guanido- 15 N 2 ]-arginine and L-[5- 13 C-3,3,4,4- 2 H 4 ]-citrulline were infused intravenously and L-[ 15 N]-phenylalanine and L-[1- 13 C]leucine enterally. Arterial blood was sampled every hour. Coefficients of variation, representing intra-individual variability, of the amino acid appearances of phenylalanine, tyrosine, leucine, arginine and citrulline were high, on average 14-19% for intravenous tracers and 23-26% for enteral tracers. No evident circadian rhythm was present. The pattern and overall 24-h level of whole body protein balance differed per individual. In continuously fed stable critically ill children, the amino acid appearances of phenylalanine, tyrosine, leucine, arginine and citrulline show high variability. This should be kept in mind when performing stable isotope studies in this population. There was no apparent circadian rhythm. NCT01511354 on clinicaltrials.gov.

Critically ill patients frequently experience severe agitation placing them at risk of harm. Physical restraint is common in intensive care units (ICUs) for clinician concerns about safety. However, physical restraint may not prevent medical device removal and has been associated with negative physical and psychological consequences. While professional society guidelines, legislation, and accreditation standards recommend physical restraint minimization, guidelines for critically ill patients are over a decade old, with recommendations that are non-specific. Our systematic review will synthesize evidence on physical restraint in critically ill adults with the primary objective of identifying effective minimization strategies. Two authors will independently search from inception to July 2016 the following: Ovid MEDLINE, CINAHL, Embase, Web of Science, Cochrane Library, PROSPERO, Joanna Briggs Institute, grey literature, professional society websites, and the International Clinical Trials Registry Platform. We will include quantitative and qualitative study designs, clinical practice guidelines, policy documents, and professional society recommendations relevant to physical restraint of critically ill adults. Authors will independently perform data extraction in duplicate and complete risk of bias and quality assessment using recommended tools. We will assess evidence quality for quantitative studies using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach and for qualitative studies using the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) guidelines. Outcomes of interest include (1) efficacy/effectiveness of physical restraint minimization strategies; (2) adverse events (unintentional device removal, psychological impact, physical injury) and associated benefits including harm prevention; (3) ICU outcomes (ventilation duration, length of stay, and mortality); (4) prevalence, incidence, patterns of use including patient and treatment characteristics and chemical restraint; (5) barriers and facilitators to minimization; (6) patient, family, and healthcare professional perspectives; (7) professional society-endorsed recommendations; and (8) evidence gaps and research priorities. We will use our systematic review findings to produce updated guidelines on physical restraint use for critically ill adults and to develop a professional society-endorsed position statement. This will foster patient and clinician safety by providing clinicians, administrators, and policy makers with a tool to promote minimal and safe use of physical restraint for critically ill adults.

To measure red blood cell 2,3-diphosphoglycerate (RBC 2,3-DPG) concentrations in early critical illness; to investigate factors associated with high or low RBC 2,3-DPG levels; to calculate in vivo P50 in patients with early critical illness; and to explore the relationship between RBC 2,3-DPG and intensive care mortality. Prospective cohort study. General medical-surgical intensive care unit (ICU) of a major Scottish teaching hospital. One-hundred eleven critically ill patients during the first 24 hrs in the ICU with no history of chronic hematologic disorders or RBC transfusion within 24 hrs and 34 age- and sex-matched healthy reference subjects. None. We measured RBC 2,3-DPG concentration, plasma biochemistry values, and arterial blood gas parameters. On average, RBC 2,3-DPG was lower among critically ill patients than controls (mean [sd], 14.1 [6.3] vs. 16.7 [3.7] mumol/g hemoglobin; p = .004) and had a wider range of values (patients, 3.2-32.5 mumol/g hemoglobin; reference group, 9.1-24.3). Regression analysis indicated a strong independent association between plasma pH and RBC 2,3-DPG (B, 32.15 [95% confidence interval, 19.07-46.22], p < .001) and a weak association with plasma chloride (B, -0.196 [95% confidence interval, -0.39 to -0.01], p = .044) but not with hemoglobin or other measured biochemical parameters. The mean calculated in vivo P50 level was normal (3.8 kPa) but varied widely among patients (range, 2.0-5.5 kPa). RBC 2,3-DPG concentration was similar for ICU survivors and nonsurvivors. RBC 2,3-DPG concentrations vary widely among critically ill patients. Acidosis is associated with lower RBC 2,3-DPG concentrations, but anemia is not associated with a compensatory increase in RBC 2,3-DPG early in critical illness. Lower RBC 2,3-DPG concentrations during the first 24 hrs of intensive care are not associated with higher ICU mortality.

Time to look beyond one-year mortality in critically ill hematological patients?

Moors, Ine; Benoit, Dominique D

2014-02-11

The spectacular improvement in long-term prognosis of patients with hematological malignancies since the 1980s, coupled with the subsequent improvement over the past decade in short- and mid-term survival in cases of critical illness, resulted in an increasing referral of such patients to the ICU. A remaining question, however, is how these patients perform in the long term with regard to survival and quality of life. Here we discuss the present multicenter study on survival beyond 1 year in critically ill patients with hematological malignancies. We conclude with suggestions on how we can further improve the long-term outcome of these patients.

Hidden Anemias in the Critically Ill.

With increasing knowledge of the risks associated with receiving blood transfusions, a new paradigm of bloodless medicine is needed. Principles of bloodless medicine include careful monitoring for obvious and hidden anemias, rapid intervention, minimizing blood losses from laboratory testing and procedures, and careful management of bleeding diatheses. As evidence is revealed and refined, standard treatment of anemia in the intensive care unit will include erythropoietin-stimulating agents, iron, folate, and vitamin B12, which will reduce risks associated with blood transfusions.

AIM: To calculate cost effectiveness of the treatment of critically ill patients in a medical intensive care unit (ICU) of a middle income country with limited access to ICU resources. METHODS: A prospective cohort study and economic evaluation of consecutive patients treated in a recently established medical ICU in Sarajevo, Bosnia and Herzegovina. A cost utility analysis of the intensive care of critically ill patients compared to the hospital ward treatment from the perspective of the health care system was subsequently performed. Incremental cost effectiveness was calculated using estimates of ICU vs non-ICU treatment effectiveness based on a formal systematic review of published studies. Decision analytic modeling was used to compare treatment alternatives. Sensitivity analyses of the key model parameters were performed. RESULTS: Out of 148 patients, seventy patients (47.2%) survived to one year after critical illness with a median quality of life index 0.64 [interquartile range(IQR) 0.49-0.76]. Median number of life years gained per patient was 30 (IQR 16-40) or 18 quality adjusted life years (QALYs) (IQR 7-28). The cost of treatment of critically ill patients varied between 1820 dollar and 20109 dollar per hospital survivor and between 100 dollar and 2514 dollar per QALY saved. Mean factors that influenced costs were: Age, diagnostic category, ICU and hospital length of stay and number and type of diagnostic and therapeutic interventions. The incremental cost effectiveness ratio for ICU treatment was estimated at 3254 dollar per QALY corresponding to 35% of per capita GDP or a Very Cost Effective category according to World Health Organization criteria. CONCLUSION: The ICU treatment of critically ill medical patients in a resource poor country is cost effective and compares favorably with other medical interventions. Public health authorities in low and middle income countries should encourage development of critical care services. PMID:27152258

Hypophosphataemia is a potentially hazardous metabolic disturbance which is common in critically ill patients. The condition is reported to be associated with severe complications and increased mortality. It is unknown, whether hypophosphataemia has a causal effect or reflects the severity of illness. There are no randomized clinical trials to support treatment of hypophosphataemia with intravenous phosphate substitution, which has resulted in large variations in monitoring and treatment of hypophosphataemia in the intensive care unit.

Objectives Self-management is promoted as a strategy for improving outcomes for serious mental illness as well as for chronic general medical conditions. This study evaluated the feasibility and effectiveness of an eight-month program combining training in self-management for both psychiatric and general medical illness, including embedded nurse care management. Methods Participants were 71 middle-aged and older adults (mean age=60.3±6.5) with serious mental illness and chronic general medical conditions who were randomly assigned to receive integrated Illness Management and Recovery (I-IMR) (N=36) or usual care (N=35). Feasibility was determined by attendance at I-IMR and nurse sessions. Effectiveness outcomes were measured two and six months after the intervention (ten- and 14-month follow-ups) and included self-management of psychiatric and general medical illness, participation in psychiatric and general medical encounters, and self-reported acute health care utilization. Results I-IMR participants attended 15.8±9.5 I-IMR and 8.2±5.9 nurse sessions, with 75% attending at least ten I-IMR and five nurse sessions. Compared with usual care, I-IMR was associated with greater improvements in participant and clinician ratings for psychiatric illness self-management, greater diabetes self-management, and an increased preference for detailed diagnosis and treatment information during primary care encounters. The proportion of I-IMR participants with at least one psychiatric or general medical hospitalization decreased significantly between baseline and ten- and 14-month follow-ups. Conclusions I-IMR is a feasible intervention for this at-risk group and demonstrated potential effectiveness by improving self-management of psychiatric illness and diabetes and by reducing the proportion of participants requiring psychi atric or general medical hospitalizations.

Frailty in the critically ill: a novel concept

PubMed Central

2011-01-01

The concept of frailty has been defined as a multidimensional syndrome characterized by the loss of physical and cognitive reserve that predisposes to the accumulation of deficits and increased vulnerability to adverse events. Frailty is strongly correlated with age, and overlaps with and extends aspects of a patient's disability status (that is, functional limitation) and/or burden of comorbid disease. The frail phenotype has more specifically been characterized by adverse changes to a patient's mobility, muscle mass, nutritional status, strength and endurance. We contend that, in selected circumstances, the critically ill patient may be analogous to the frail geriatric patient. The prevalence of frailty amongst critically ill patients is currently unknown; however, it is probably increasing, based on data showing that the utilization of intensive care unit (ICU) resources by older people is rising. Owing to the theoretical similarities in frailty between geriatric and critically ill patients, this concept may have clinical relevance and may be predictive of outcomes, along with showing important interaction with several factors including illness severity, comorbid disease, and the social and structural environment. We believe studies of frailty in critically ill patients are needed to evaluate how it correlates with outcomes such as survival and quality of life, and how it relates to resource utilization, such as length of mechanical ventilation, ICU stay and duration of hospitalization. We hypothesize that the objective measurement of frailty may provide additional support and reinforcement to clinicians confronted with end-of-life decisions on the appropriateness of ICU support and/or withholding of life-sustaining therapies.

Healthcare improvement as planned system change or complex responsive processes? a longitudinal case study in general practice

PubMed Central

2013-01-01

Background Interest in how to implement evidence-based practices into routine health care has never been greater. Primary care faces challenges in managing the increasing burden of chronic disease in an ageing population. Reliable prescriptions for translating knowledge into practice, however, remain elusive, despite intense research and publication activity. This study seeks to explore this dilemma in general practice by challenging the current way of thinking about healthcare improvement and asking what can be learned by looking at change through a complexity lens. Methods This paper reports the local level of an embedded case study of organisational change for better chronic illness care over more than a decade. We used interviews, document review and direct observation to explore how improved chronic illness care developed in one practice. This formed a critical case to compare, using pattern matching logic, to the common prescription for local implementation of best evidence and a rival explanation drawn from complexity sciences interpreted through modern sociology and psychology. Results The practice changed continuously over more than a decade to deliver better chronic illness care in line with research findings and policy initiatives – re-designing care processes, developing community linkages, supporting patient self-management, using guidelines and clinical information systems, and integrating nurses into the practice team. None of these improvements was designed and implemented according to an explicit plan in response to a documented gap in chronic disease care. The process that led to high quality chronic illness care exhibited clear complexity elements of co-evolution, non-linearity, self-organisation, emergence and edge of chaos dynamics in a network of agents and relationships where a stable yet evolving way of organizing emerged from local level communicative interaction, power relating and values based choices. Conclusions The current discourse of implementation science as planned system change did not match organisational reality in this critical case of improvement in general practice. Complexity concepts translated in human terms as complex responsive processes of relating fit the pattern of change more accurately. They do not provide just another fashionable blueprint for change but inform how researchers, policymakers and providers participate in improving healthcare. PMID:23617833

Clinical review: Critical care in the global context – disparities in burden of illness, access, and economics

World health care expenditures exceed US $4 trillion. However, there is marked variation in global health care spending, from upwards of US $7,000 per capita in the US to under US $25 per capita in most of sub-Saharan Africa. In developed countries, care of the critically ill comprises a large proportion of health care spending; however, in developing countries, with a greater burden of both illness and critical illness, there is little infrastructure to provide care for these patients. There is sparse research to inform the needs of critically ill patients, but often basic requirements such as trained personnel, medications, oxygen, diagnostic and therapeutic equipment, reliable power supply, and safe transportation are unavailable. Why should this be a focus of intensivists of the developed world? Nearly all of those dying in developing countries would be our patients without the accident of latitude. Tailored to the needs of the region, the provision of critical care has a role, even in the context of limited preventive and primary care. Internationally and locally driven solutions are needed. We can help by recognizing the '10/90 gap' that is pervasive within global health care and our profession by educating ourselves of needs, contacting and collaborating with colleagues in the developing world, and advocating that our professional societies and funding agencies consider an increasingly global perspective in education and research.

Interstitial pneumonia with autoimmune features (IPAF) identifies a recently recognized autoimmune syndrome characterized by interstitial lung disease and autoantibodies positivity, but absence of a specific connective tissue disease diagnosis or alternative etiology. We retrospectively reviewed the clinical presentation, diagnostic workup and management of seven critically ill patients who met diagnostic criteria for IPAF. We compared baseline characteristics and clinical outcome of IPAF patients with those of the population of ARDS patients admitted in the same period. Seven consecutive patients with IPAF admitted to intensive care unit for acute respiratory distress syndrome (ARDS) were compared with 78 patients with ARDS secondary to a known risk factor and with eight ARDS patients without recognized risk factors. Five IPAF patients (71%) survived and were discharged alive from ICU: Their survival rate was equal to that of patients with a known risk factor (71%), while the subgroup of patients without risk factors had a markedly lower survival (38%). According to the Berlin definition criteria, ARDS was severe in four IPAF patients and moderate in the remaining three. All had multiple organ dysfunction at presentation. The most frequent autoantibody detected was anti-SSA/Ro52. All patients required prolonged mechanical ventilation (median duration 49 days, range 10-88); four received extracorporeal membrane oxygenation and one received low-flow extracorporeal CO 2 removal. All patients received immunosuppressive therapy. This is the first description of a cohort of critical patients meeting the diagnostic criteria for IPAF presenting with ARDS. This diagnosis should be considered in any critically ill patient with interstitial lung disease of unknown origin. While management is challenging and level of support high, survival appears to be good and comparable to that of patients with ARDS associated with a known clinical insult.

Development and evaluation of a critical care e-learning scenario.

This paper describes the development and evaluation of a critical care e-learning scenario for student nurses. At present, there are insufficient opportunities in the United Kingdom (UK) for student nurses to experience clinical placements where their skills in care of the critically-ill can be developed. There is therefore a need for new learning materials that help learners recognise the signs of clinical deterioration and rehearse the management of critically-ill patients. One way of meeting this need is by using electronic care scenarios. Several electronic care scenarios have been developed at Swansea University as part of the eWARD project. This article describes the design and evaluation of a critical care scenario that follows the care of a road casualty (John Macadam) after admission to an intensive care unit. The scenario was designed by an advisory team comprising a clinical lecturer and e-learning specialists. After using the scenario, 144 nursing students completed a Web-based questionnaire that collected demographic and attitudinal data for analysis using SPSS. Nursing students had a strongly positive attitude to the scenario with median scores in excess of 20 compared to maxima of 25 for scales measuring ease-of-use, interactivity, realism and confidence. None of the demographic data collected had a significant effect on these attitudes. The positive attitude of student nurses to this scenario strongly supports its use to help learners to (1) acquire knowledge and awareness when real life placements in these settings are not available and (2) extend their knowledge after coming across similar situations in practice.

Evidence-based hypnotherapy for asthma: a critical review.

PubMed

Brown, Daniel

2007-04-01

Asthma is a chronic disease with intermittent acute exacerbations, characterized by obstructed airways, hyper-responsiveness, and sometimes by chronic airway inflammation. Critically reviewing evidence primarily from controlled outcome studies on hypnosis for asthma shows that hypnosis is possibly efficacious for treatment of symptom severity and illness-related behaviors and is efficacious for managing emotional states that exacerbate airway obstruction. Hypnosis is also possibly efficacious for decreasing airway obstruction and stabilizing airway hyper-responsiveness in some individuals, but there is insufficient evidence that hypnosis affects asthma's inflammatory process. Promising research needs to be replicated with larger samples and better designs with careful attention paid to the types of hypnotic suggestions given. The critical issue is not so much whether it is used but how it is used. Future outcome research must address the relative contribution of expectancies, hypnotizability, hypnotic induction, and specific suggestions.

Leveraging Partnerships: Families, Schools, and Providers Working Together to Improve Asthma Management.

Asthma is one of the most common illnesses of school-aged children and can lead to both health and educational disparities. Children from low socioeconomic backgrounds and racial/ethnic minorities suffer the greatest impact. They often lack the asthma self-management skills to successfully monitor, navigate, and negotiate appropriate asthma care. School settings are a strategic point of contact for this additional support. School nurses can monitor for signs of asthma worsening, manage symptoms, provide care coordination, and reinforce self-management skills. Likewise, school-based asthma programs have the potential to reduce health and educational disparities, but it is the strong linkage to the asthma care provider that is critical to successful school-based asthma management. Healthcare providers are encouraged to establish partnerships with families through patient-centered care and schools through clear communication and care coordination to ensure asthma is well controlled so the child is in school and ready to learn.

Food and meals in caring institutions - a small dive into research.

Hansen, Kai Victor

2016-05-09

Purpose - With the growing older population, the increasing interest in the elderly's eating habits and the meal situation go hand in hand and are challenges in many countries, including Norway. The purpose of this paper is to investigate, part of an ongoing project in Norway, address four categories of elderly people: healthy elderly (HE), old people with home care, elderly living in institutions, and critical ill elderly. Design/methodology/approach - The aim of this study was to investigate related articles concerning food and the elderly in the four identified categories, defining six different meal experience categories to disclose possible gaps in the research in terms of core product, room, personal service, company, atmosphere, and management control systems (MCS). Database searches, conducted through JSTOR and Web of Science, started with words in combination with "elderly and meal experiences" and were narrowed down to the most relevant papers with words from the six meal experience categories. Ultimately, 21 of 51 downloaded papers from international journals were reviewed. Findings - A comparison of the four elderly groups was made across the six different meal experience categories, which disclosed several gaps. Among the 21 papers, five focused on HE, 12 on older people living with home care, 16 on elderly living in institutions, and one on critical ill elderly. The specific under-researched gaps include room, company, atmosphere, and MCS. Research limitations/implications - Future research will need to investigate these groups more thoroughly, and the research should concentrate on the HE and critical ill in connection with the six meal experience aspects. Originality/value - The combination of meal experience aspects towards different elderly categories is an original perspective on the aim of the literature review.

Guidance on managing the nutritional requirements of critically ill patients in the intensive care unit (ICU) has been issued by several international bodies. While these guidelines are consulted in ICUs across the Asia-Pacific and Middle East regions, there is little guidance available that is tailored to the unique healthcare environments and demographics across these regions. Furthermore, the lack of consistent data from randomized controlled clinical trials, reliance on expert consensus, and differing recommendations in international guidelines necessitate further expert guidance on regional best practice when providing nutrition therapy for critically ill patients in ICUs in Asia-Pacific and the Middle East. The Asia-Pacific and Middle East Working Group on Nutrition in the ICU has identified major areas of uncertainty in clinical practice for healthcare professionals providing nutrition therapy in Asia-Pacific and the Middle East and developed a series of consensus statements to guide nutrition therapy in the ICU in these regions. Accordingly, consensus statements have been provided on nutrition risk assessment and parenteral and enteral feeding strategies in the ICU, monitoring adequacy of, and tolerance to, nutrition in the ICU and institutional processes for nutrition therapy in the ICU. Furthermore, the Working Group has noted areas requiring additional research, including the most appropriate use of hypocaloric feeding in the ICU. The objective of the Working Group in formulating these statements is to guide healthcare professionals in practicing appropriate clinical nutrition in the ICU, with a focus on improving quality of care, which will translate into improved patient outcomes.

Background: At the onset of acute hypoxic respiratory failure, critically ill patients with acute lung injury (ALI) may be difficult to distinguish from those with cardiogenic pulmonary edema (CPE). No single clinical parameter provides satisfying prediction. We hypothesized that a combination of those will facilitate early differential diagnosis. Methods: In a population-based retrospective development cohort, validated electronic surveillance identified critically ill adult patients with acute pulmonary edema. Recursive partitioning and logistic regression were used to develop a decision support tool based on routine clinical information to differentiate ALI from CPE. Performance of the score was validated in an independent cohort of referral patients. Blinded post hoc expert review served as gold standard. Results: Of 332 patients in a development cohort, expert reviewers (κ, 0.86) classified 156 as having ALI and 176 as having CPE. The validation cohort had 161 patients (ALI = 113, CPE = 48). The score was based on risk factors for ALI and CPE, age, alcohol abuse, chemotherapy, and peripheral oxygen saturation/Fio2 ratio. It demonstrated good discrimination (area under curve [AUC] = 0.81; 95% CI, 0.77-0.86) and calibration (Hosmer-Lemeshow [HL] P = .16). Similar performance was obtained in the validation cohort (AUC = 0.80; 95% CI, 0.72-0.88; HL P = .13). Conclusions: A simple decision support tool accurately classifies acute pulmonary edema, reserving advanced testing for a subset of patients in whom satisfying prediction cannot be made. This novel tool may facilitate early inclusion of patients with ALI and CPE into research studies as well as improve and rationalize clinical management and resource use. PMID:22030803

The role played by fever in the outcome of critical illness in children is unclear. This survey of medical and nursing staff in 35 paediatric intensive care units and transport teams in the United Kingdom and Ireland established attitudes towards the management of children with fever. Four hundred sixty-two medical and nursing staff responded to a web-based survey request. Respondents answered eight questions regarding thresholds for temperature control in usual clinical practice, indications for paracetamol use, and readiness to participate in a clinical trial of permissive temperature control. The median reported threshold for treating fever in clinical practice was 38 °C (IQR 38-38.5 °C). Paracetamol was reported to be used as an analgesic and antipyretic but also for non-specific comfort indications. There was a widespread support for a clinical trial of a permissive versus a conservative approach to fever in paediatric intensive care units. Within a trial, 58% of the respondents considered a temperature of 39 °C acceptable without treatment. Staff on paediatric intensive care units in the United Kingdom and Ireland tends to treat temperatures within the febrile range. There was a willingness to conduct a randomized controlled trial of treatment of fever. What is known: • The effect of fever on the outcome in paediatric critical illness is unknown. • Paediatricians have traditionally been reluctant to allow fever in sick children. What is new: • Paediatric intensive care staff report a tendency towards treating fever, with a median reported treatment threshold of 38 °C. • There is widespread support amongst PICU staff in the UK for a randomized controlled trial of temperature in critically ill children. • Within a trial setting, PICU staff attitudes to fever are more permissive than in clinical practice.

In critically ill surgical patients undergoing abdominal negative-pressure wound therapy (NPWT), it remains uncertain whether or not intra-abdominal pressure (IAP) measurements should be obtained when NPWT is activated. We aimed to determine agreement between IAP measured with and without NPWT. In this analytic cross-sectional study, critically ill surgical adults (≥18 y) requiring abdominal NPWT for temporary abdominal closure after a damage control laparotomy were selected. Patients with urinary tract injuries or with pelvic packing were excluded. Paired IAP measures were performed in the same patient, with and without NPWT; two different operators performed the measures unaware of the other's result. Bland-Altman methods assessed the agreement between the two measures. Subgroup analyses (trauma and nontrauma) were performed. There were 198 IAP measures (99 pairs) in 38 patients. Mean IAP with and without NPWT were 8.33 (standard deviation 4.01) and 8.65 (standard deviation 4.04), respectively. Mean IAP difference was -0.323 (95% confidence interval -0.748 to 0.101), and reference range for difference was -4.579 to 3.932 (P = 0.864). From 112 IAP measures (56 pairs) in 21 trauma patients, mean IAP difference was -0.268 (95% confidence interval -0.867 to 0.331), and reference range for the difference was -4.740 to 4.204 (P = 0.427). There was no statistically significant disagreement in IAP measures. IAP could be measured with or without NPWT. In critically ill surgical patients with abdominal NPWT for temporary abdominal closure, monitoring and management of IAP either with or without NPWT is recommended. Copyright © 2018 Elsevier Inc.

Providers have traditionally established priorities for quality improvement; however, patients and their family members have recently become involved in priority setting. Little is known about how to reconcile priorities of different stakeholder groups into a single prioritized list that is actionable for organizations. To describe the decision-making process for establishing consensus used by a diverse panel of stakeholders to reconcile two sets of quality improvement priorities (provider/decision maker priorities n=9; patient/family priorities n=19) into a single prioritized list. We employed a modified Delphi process with a diverse group of panellists to reconcile priorities for improving care of critically ill patients in the intensive care unit (ICU). Proceedings were audio-recorded, transcribed and analysed using qualitative content analysis to explore the decision-making process for establishing consensus. Nine panellists including three providers, three decision makers and three family members of previously critically ill patients. Panellists rated and revised 28 priorities over three rounds of review and reached consensus on the "Top 5" priorities for quality improvement: transition of patient care from ICU to hospital ward; family presence and effective communication; delirium screening and management; early mobilization; and transition of patient care between ICU providers. Four themes were identified as important for establishing consensus: storytelling (sharing personal experiences), amalgamating priorities (negotiating priority scope), considering evaluation criteria and having a priority champion. Our study demonstrates the feasibility of incorporating families of patients into a multistakeholder prioritization exercise. The approach described can be used to guide consensus building and reconcile priorities of diverse stakeholder groups. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

The private struggle of mothers with asthma: a gender perspective on illness management.

Little attention has been paid to the specific problems of mothers with chronic illness. In this study of mothers with asthma, we asked the question: "how do they manage their illness"? We interviewed a purposive sample of four Dutch and four Canadian mothers living with asthma and varying in age and socio-economic class. Our analysis explored challenges the mothers face, three main strategies of non-medical illness management (prevention, normalization and mobilizing support), and the influence of age and class differences. Unhealthy cycles of living with asthma are identified and suggestions for mother-specific interventions are offered. By drawing attention to the gendered nature of chronic illness management and to patients' own experiences, a more useful frame of reference is created for professionals who do not have first hand knowledge of living with a chronic illness.

Equipoise exists regarding the benefits of restricting caloric intake during electrolyte replacement for refeeding syndrome, with half of intensive care specialists choosing to continue normal caloric intake. We aimed to assess whether energy restriction affects the duration of critical illness, and other measures of morbidity, compared with standard care. We did a randomised, multicentre, single-blind clinical trial in 13 hospital intensive care units (ICUs) in Australia (11 sites) and New Zealand (two sites). Adult critically ill patients who developed refeeding syndrome within 72 h of commencing nutritional support in the ICU were enrolled and allocated to receive continued standard nutritional support or protocolised caloric restriction. 1:1 computer-based randomisation was done in blocks of variable size, stratified by enrolment serum phosphate concentration (>0·32 mmol/L vs ≤0·32 mmol/L) and body-mass index (BMI; >18 kg/m(2)vs ≤18 kg/m(2)). The primary outcome was the number of days alive after ICU discharge, with 60 day follow-up, in a modified intention-to-treat population of all randomly allocated patients except those mistakenly enrolled. Days alive after ICU discharge was a composite outcome based on ICU length of stay, overall survival time, and mortality. The Refeeding Syndrome Trial was registered with the Australian and New Zealand Clinical Trials Registry (ANZCTR number 12609001043224). Between Dec 3, 2010, and Aug 13, 2014, we enrolled 339 adult critically ill patients: 170 were randomly allocated to continued standard nutritional support and 169 to protocolised caloric restriction. During the 60 day follow-up, the mean number of days alive after ICU discharge in 165 assessable patients in the standard care group was 39·9 (95% CI 36·4-43·7) compared with 44·8 (95% CI 40·9-49·1) in 166 assessable patients in the caloric restriction group (difference 4·9 days, 95% CI -2·3 to 13·6, p=0·19). Nevertheless, protocolised caloric restriction improved key individual components of the primary outcome: more patients were alive at day 60 (128 [78%] of 163 vs 149 [91%] of 164, p=0·002) and overall survival time was increased (48·9 [SD 1·46] days vs 53·65 [0·97] days, log-rank p=0·002). Protocolised caloric restriction is a suitable therapeutic option for critically ill adults who develop refeeding syndrome. We did not identify any safety concerns associated with the use of protocolised caloric restriction. National Health and Medical Research Council of Australia. Copyright © 2015 Elsevier Ltd.

Background Delirium is frequently diagnosed in critically ill patients and is associated with poor clinical outcomes. Haloperidol is the most commonly used drug for delirium despite little evidence of its effectiveness. The aim of this study was to establish whether early treatment with haloperidol would decrease the time that survivors of critical illness spent in delirium or in coma. Methods We did this double-blind, placebo-controlled randomised trial in a general adult intensive care unit (ICU). Critically ill patients (≥18 years) needing mechanical ventilation within 72 of admission were enrolled. Patients were randomised (by an independent nurse, in 1:1 ratio, with permuted block size of four and six, using a centralised, secure web-based randomisation service) to receive haloperidol 2·5mgs or 0·9% saline placebo intravenously every 8 h irrespective of coma or delirium status. Study drug was discontinued on ICU discharge, once delirium-free and coma-free for 2 consecutive days, or after a maximum of 14 days treatment, which ever came first. Delirium was assessed using the confusion assessment method - for the ICU (CAM-ICU). The primary outcome was delirium-free and coma-free days, defined as the number of days in the first 14 days after randomisation during which the patient was alive without delirium and not in coma from any cause. Patients who died within the 14-day study period were recorded as having 0 days free of delirium and coma. ICU clinical and research staff and patients were masked to treatment throughout the study. Analyses were by intention to treat. This trial is registered with the International Standard Randomised Controlled Trial Registry, number ISRCTN83567338. Findings 142 patients were randomised, 141 were included in the final analysis (71 haloperidol, 70 placebo). Patients in the haloperidol group spent about the same number of days alive, without delirium, and without coma as did patients in the placebo group (median 5 days [IQR 0-10] vs 6 days [0-11] days; p= 0·53). The most common adverse events were oversedation (11 patients in the haloperidol group vs. six in the placebo) and QTc prolongation (seven in haloperidol group and six in the placebo group). No patient had a serious adverse event related to study drug. Interpretation These results do not support the hypothesis that haloperidol modifies duration of delirium in critically ill patients. Although haloperidol can be used safely in this population of patients, pending the results of trials in progress, the use of intravenous haloperidol should be reserved for the short-term management of acute agitation.

No patient had a serious adverse event related to the study drug. These results do not support the hypothesis that haloperidol modifies duration of delirium in critically ill patients. Although haloperidol can be used safely in this population of patients, pending the results of trials in progress, the use of intravenous haloperidol should be reserved for short-term management of acute agitation.

To provide a narrative review of the latest concepts and understanding of the pathophysiology of critical illness-related corticosteroid insufficiency (CIRCI). A multispecialty task force of international experts in critical care medicine and endocrinology and members of the Society of Critical Care Medicine (SCCM) and the European Society of Intensive Care Medicine (ESICM). Medline, Database of Abstracts of Reviews of Effects (DARE), Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Database of Systematic Reviews. Three major pathophysiologic events were considered to constitute CIRCI: dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, altered cortisol metabolism, and tissue resistance to glucocorticoids. The dysregulation of the HPA axis is complex, involving multidirectional crosstalk between the CRH/ACTH pathways, autonomic nervous system, vasopressinergic system, and immune system. Recent studies have demonstrated that plasma clearance of cortisol is markedly reduced during critical illness, explained by suppressed expression and activity of the primary cortisol-metabolizing enzymes in the liver and kidney. Despite the elevated cortisol levels during critical illness, tissue resistance to glucocorticoids is believed to occur due to insufficient glucocorticoid alpha-mediated anti-inflammatory activity. Novel insights into the pathophysiology of CIRCI add to the limitations of the current diagnostic tools to identify at-risk patients and may also impact how corticosteroids are used in patients with CIRCI.

Depression in medically ill patients occurs at twice the rate found in the general population. Though pharmacologic and psychotherapeutic interventions for depression are effective, response to treatment and access to care are barriers for this population. A multidimensional telehealth intervention was designed to focus on these barriers by delivering a phone based intervention that addressed managing one's illness and coping emotionally. Veterans with diabetes, hypertension, or chronic pain and depressive symptoms were randomized to one of three conditions: Usual Care (n=23), Illness Management Only (n=31), or Combined Psychotherapy and Illness Management (n=29). Those randomized to the Combined or Illness Management Only intervention group received 10 phone visits. Veterans in the Combined group received all aspects of the illness management program plus a manualized depression intervention. Subjects completed assessments at baseline, week 5, and 10 to test the main hypothesis that veterans in the Combined condition would have a greater decline in depressive symptoms. The Combined intervention yielded a significant decline in depressive symptoms when compared with Usual Care. However, the there was no significant difference between the Combined and Illness Management Only groups. This is a pilot study with a small sample size relative to a standard randomized controlled trial in psychotherapy. This telephone-based intervention succeeded in reducing depressive symptoms in veterans with chronic illness. It adds to the building evidence base for providing phone-delivered mental health services. © 2013 Elsevier B.V. All rights reserved.

Women's self-management of chronic illnesses in the context of caregiving: a grounded theory study.

PubMed

Martinez-Marcos, Mercedes; De la Cuesta-Benjumea, Carmen

2015-06-01

Uncover how women self-manage their own chronic illness while taking care of a dependent relative. International policies place special emphasis in promoting interventions addressed to control, prevent and care for people with chronic health conditions. Self-management is a crucial part of this care. Caregivers are more prone to have chronic illness than non-caregivers. They are confronted with dilemmas about taking care of themselves while taking care of their dependent relative and the rest of their families. Caregivers articulate strategies to enable them to focus their energy on caring. Qualitative study using constructivist grounded theory. Thirty-nine women caregivers with a chronic illness participated in the study. Twenty-three semi-structured interviews and two focus groups were carried out between April 2010-December 2011. Data were analysed using grounded theory procedures. Self-management helps women caregivers with a chronic illness to balance the demands of their own illness and those of the dependent relative. They self-manage their illness by self-regulating the treatment, by regulating their strength and by controlling their emotions. Women caregivers integrate effectively and creatively the management of their chronic illnesses within the complexities of family care. This renders their health needs invisible and reaffirms them as capable caregivers. Identifying self-management strategies of women caregivers allow health professionals to acknowledge and reinforce effective self-care measures and to deter those that are ineffective and lessen their quality of life. © 2014 John Wiley & Sons Ltd.

Rethinking 'risk' and self-management for chronic illness.

PubMed

Morden, Andrew; Jinks, Clare; Ong, Bie Nio

2012-02-01

Self-management for chronic illness is a current high profile UK healthcare policy. Policy and clinical recommendations relating to chronic illnesses are framed within a language of lifestyle risk management. This article argues the enactment of risk within current UK self-management policy is intimately related to neo-liberal ideology and is geared towards population governance. The approach that dominates policy perspectives to 'risk' management is critiqued for positioning people as rational subjects who calculate risk probabilities and act upon them. Furthermore this perspective fails to understand the lay person's construction and enactment of risk, their agenda and contextual needs when living with chronic illness. Of everyday relevance to lay people is the management of risk and uncertainty relating to social roles and obligations, the emotions involved when encountering the risk and uncertainty in chronic illness, and the challenges posed by social structural factors and social environments that have to be managed. Thus, clinical enactments of self-management policy would benefit from taking a more holistic view to patient need and seek to avoid solely communicating lifestyle risk factors to be self-managed.

Multiple barriers to transthoracic echocardiography are present in critically ill infants immediately after surgery. Transesophageal echocardiography (TEE) is sometimes needed to obtain specific important information that transthoracic echocardiography fails to demonstrate. Formerly, the investigators used the AcuNav intracardiac echocardiographic (ICE) intravascular ultrasound transducer (8 Fr, 2.5 mm, 64-element crystal array, multifrequency [5.5-10 MHz], single longitudinal plane, linear phased array [Siemens Medical Solutions USA, Inc., Mountain View, CA]). Recently, the investigators have also used the microTEE transducer (8-mm transducer tip, 5.2-mm shaft, multifrequency [3-8 MHz], multiplane phased array, 32-element probe [Philips Medical Systems, Andover, MA]). Both transducers have two-dimensional, M-mode, color Doppler, and pulsed-wave and continuous-wave Doppler capabilities. The aim of this study was to compare the efficacy, safety, ease of insertion, capabilities, utilization, and cost of the AcuNav ICE transducer versus those of the microTEE transducer. A retrospective review of all 50 postoperative critically ill infants who underwent TEE using the AcuNav and microTEE in the past 5 years was conducted. TEE was performed as ordered by the attending physician to answer a specific question not answered by transthoracic echocardiography. In all cases, the clinical information sought was obtained. The AcuNav ICE transducer was safe, easy to insert through the transnasal route, and did not require paralysis; however, it had a limited number of echocardiographic views and had greater sterilization cost. The microTEE transducer had greater echocardiographic capabilities and lower sterilization cost; however, it was slightly more difficult to insert, had a few manageable complications, and required more sedation and paralysis. TEE in this setting has increased because of demonstrated efficacy and safety. Both the AcuNav ICE and microTEE transducers are useful and effective in this critical clinical scenario.

E-mental health is a promising medium to keep mental health affordable and accessible. For consumers with severe mental illness the evidence of the effectiveness of e-health is limited. A number of difficulties and barriers have to be addressed concerning e-health for consumers with severe mental illness. One possible solution might be to blend e-health with face-to-face delivery of a recovery-oriented treatment, like the Illness Management & Recovery (IMR) programme. This paper describes the development of an e-health application for the IMR programme and the design of an early clustered randomized controlled trial. We developed the e-IMR intervention according to the six-step protocol of Intervention Mapping. Consumers joined the development group to address important and relevant issues for the target group. Decisions during the six-step development process were based on qualitative evaluations of the Illness Management & Recovery programme, structured interviews, discussion in the development group, and literature reviews on qualitative papers concerning consumers with severe mental illness, theoretical models, behavioural change techniques, and telemedicine for consumers with severe mental illness. The aim of the e-IMR intervention is to help consumers with severe mental illness to involve others, manage achieving goals, and prevent relapse. The e-IMR intervention consists of face-to-face delivery of the Illness Management & Recovery programme and an e-health application containing peer-testimonials on videos, follow up on goals and coping strategies, monitoring symptoms, solving problems, and communication opportunities. We designed an early cluster randomized controlled trial that will evaluate the e-IMR intervention. In the control condition the Illness Management & Recovery programme is provided. The main effect-study parameters are: illness management, recovery, psychiatric symptoms severity, self-management, quality of life, and general health. The process of the IMR program will be evaluated on fidelity and feasibility in semi-structured interviews with participants and trainers. Intervention Mapping provided a systematic procedure for the development of this e-health intervention for consumers with severe mental illness and the preparation of an early randomized controlled trial. The trial is registered in the Dutch Trial Register: NTR4772 .

Understanding health economic analysis in critical care: insights from recent randomized controlled trials.

PubMed

Sud, Sachin; Cuthbertson, Brian H

2011-10-01

The article reviews the methods of health economic analysis (HEA) in clinical trials of critically ill patients. Emphasis is placed on the usefulness of HEA in the context of positive and 'no effect' studies, with recent examples. The need to control costs and promote effective spending in caring for the critically ill has garnered considerable attention due to the high cost of critical illness. Many clinical trials focus on short-term mortality, ignoring costs and quality of life, and fail to change clinical practice or promote efficient use of resources. Incorporating HEA into clinical trials is a possible solution. Such studies have shown some interventions, although expensive, provide good value, whereas others should be withdrawn from clinical practice. Incorporating HEA into randomized controlled trials (RCTs) requires careful attention to collect all relevant costs. Decision trees, modeling assumptions and methods for collecting costs and measuring outcomes should be planned and published beforehand to minimize bias. Costs and cost-effectiveness are potentially useful outcomes in RCTs of critically ill patients. Future RCTs should incorporate parallel HEA to provide both economic outcomes, which are important to the community, alongside patient-centered outcomes, which are important to individuals.

Protein-energy nutrition in the ICU is the power couple: A hypothesis forming analysis.

2016-08-01

We hypothesize that an optimal and simultaneous provision of energy and protein is favorable to clinical outcome of the critically ill patients. We conducted a review of the literature, obtained via electronic databases and focused on the metabolic alterations during critical illness, the estimation of energy and protein requirements, as well as the impact of their administration. Critically ill patients undergo severe metabolic stress during which time a great amount of energy and protein is utilized in a variety of reactions essential for survival. Energy provision for critically ill patients has drawn attention given its association with morbidity, survival and long-term recovery, but protein provision is not sufficiently taken into account as a critical component of nutrition support that influences clinical outcome. Measurement of energy expenditure is done by indirect calorimetry, but protein status cannot be measured with a bedside technology at present. Recent studies suggest the importance of optimal and combined provision of energy and protein to optimize clinical outcome. Clinical randomized controlled studies measuring energy and protein targets should confirm this hypothesis and therefore establish energy and protein as a power couple.

Ethiopia has scaled up integrated community case management of childhood illness (iCCM) in most regions. We assessed the strength of iCCM implementation and the quality of care provided by health extension workers (HEWs). Data collectors observed HEWs' consultations with sick children and carried out gold standard re-examinations. Nearly all HEWs received training and supervision, and essential commodities were available. HEWs provided correct case management for 64% of children. The proportions of children correctly managed for pneumonia, diarrhea, and malnutrition were 72%, 79%, and 59%, respectively. Only 34% of children with severe illness were correctly managed. Health posts saw an average of 16 sick children in the previous 1 month. These results show that iCCM can be implemented at scale and that community-based HEWs can correctly manage multiple illnesses. However, to increase the chances of impact on child mortality, management of severe illness and use of iCCM services must be improved. PMID:24799369

Dyadic Analysis of Illness Perceptions Among Persons with Mild Cognitive Impairment and Their Family Members.

To characterize illness perceptions among persons with mild cognitive impairment (PWMCI) and their family care partners, and to examine whether PWMCI's and their family care partners' illness perceptions were associated with their own, as well as the other member of the dyad's, emotional reactions to MCI. This cross-sectional study of PWMCI and their family care partners (n = 60 dyads) used patient and relative versions of the Revised Illness Perception Questionnaire (IPQ-R) to assess metacognitive and emotional features of illness perception in MCI along 5 dimensions of perceived: seriousness of potential consequences, personal controllability, timeline, fluctuation (cycling) of symptoms, and illness coherence (clear vs. confusing). As compared to family members, PWMCI perceived MCI to be less potentially serious and to be more within their personal control, but dyads otherwise shared similar perceptions of MCI. Among PWMCI, perceived seriousness of the potential consequences of MCI was the only dimension to be significantly correlated with emotional distress. For family members, increased MCI-related emotional distress was significantly associated with perceptions of MCI as potentially serious, permanent, or confusing. A dyadic analysis using APIM showed that MCI-related emotional distress, in both PWMCI and family members, was linked to the PWMCI's perception of the seriousness of MCI. MCI-related education and support should be tailored for both the PWMCI and family member audiences, while acknowledging interdependence of illness perceptions within family units. Tailored information and support will be critical in managing MCI going forward, as illness perceptions are likely key factors on which individuals will plan for the future or base medical decisions. © The Author 2015.

Self-management support forms a central aspect of chronic Illness management nationally and globally. Evidence for the success of self-management support has mainly focussed on individually-centred outcomes of behavioural change. While it is recognised that social network members play an important role there is currently a gap in knowledge regarding who provides what type of support and under what circumstances. This is relevant for understanding the division of labour and the meeting of needs for those living with a long-term condition. We therefore took a network approach to explore self-management support conceptualising it as types of illness ‘work’ undertaken within peoples’ social networks. 300 people from deprived areas and with chronic illnesses took part in a survey conducted in 2010 in the North West of England. A concentric circles diagram was used as a research tool with which participants identified 2,544 network members who contributed to illness management. The results provide an articulation of how social network members are substantially involved in illness management. Whilst partners and close family make the highest contributions there is evidence of inputs from a wide range of relationships. Network member characteristics (type of relationship, proximity, frequency of contact) impact on the amount of illness work undertaken in peoples’ networks. In networks with ‘no partner’ other people tend to contribute more in the way of illness related work than in networks with a partner. This indicates a degree of substitutability between differently constituted networks, and that the level and type of input by different members of a network might change according to circumstances. A network perspective offers an opportunity to redress the balance of an exclusively individual focus on self-management because it addresses the broader set of contributions and resources available to people in need of chronic illness management and support.

To compare serum total, serum free and salivary cortisol in critically ill children. Prospective observational cohort study. Tertiary pediatric critical care unit at Ronald McDonald Children's Hospital at Loyola University Medical Center. We enrolled 59 patients (4 weeks to 18 years of age) between January 2012 and May 2013. Thirty-four patients were included in the salivary to serum free cortisol correlational analysis. Blood and saliva samples were obtained simultaneously within 24 hours of admission between the hours of 6 AM and 12 PM. Salivary cortisol was tested by liquid chromatography/tandem mass spectrometry, serum free cortisol by liquid chromatography/tandem mass spectrometry followed by equilibrium dialysis, and serum total cortisol by liquid chromatography/tandem mass spectrometry. Salivary and serum free cortisol values from 34 patients had a correlation coefficient (r) of 0.87 (95% CI, 0.75-0.93; p < 0.0001). The total serum and salivary cortisol values had a correlation coefficient (r) of 0.67 (95% CI, 0.42-0.81; p < 0.0001). The total serum and serum free cortisol values had a correlation coefficient (r) of 0.83 (95% CI, 0.69-0.91; p < 0.0001). Serum free and salivary cortisol values correlate in critically ill children. Salivary cortisol can be used as a surrogate for serum free cortisol in critically ill pediatric patients. Salivary cortisol is a cost-effective and less invasive measure of bioavailable cortisol and offers an alternate and accurate method for assessing critical illness-related corticosteroid insufficiency in children.

In many developing countries, including those of sub-Saharan Africa, care of the critically ill is poorly developed. We sought to elucidate the characteristics and outcomes of critically ill patients in order to better define the burden of disease and identify strategies for improving care. We conducted a cross sectional observation study of patients admitted to the intensive care unit at Kamuzu Central Hospital in 2010. Demographics, patient characteristics, clinical specialty and outcome data was collected for the 234 patients admitted during the study period. Older age and admission from trauma, general surgery or medical services were associated with increased mortality. The lowest mortality was among obstetrical and gynaecology patients. Use of the ventilator and transfusions were not associated with increased mortality. Patients with head injuries had the highest mortality rate. Rationing of critical care resources, using admitting diagnosis or scoring tools, can maximize access to critical care services in resource-limited settings. Furthermore, improvements of critical care services will be central to future efforts to reduce surgical morbidity and mortality and improving outcomes in all critically ill patients.

Shivering in acutely ill vulnerable populations.

PubMed

Holtzclaw, Barbara J

2004-01-01

The hazards of thermoregulatory shivering in the critically ill are often overlooked by caregivers. Shivering may accompany heat loss from bathing, dressing, transport, and many therapeutic activities. Febrile shivering is common during chills of fever, blood product transfusions, administration of antigenic drugs, and chemotherapy. Many patients are at risk for shivering and its negative consequences that increase oxygen expenditure and cardiorespiratory effort. Learning how underlying thermoregulatory mechanisms are involved in shivering clarifies how temperature gradients and environmental stimuli induce the shivering response. Knowledge of the anatomical progression of shivering equips the nurse to recognize or prevent this energy-consuming response. This article discusses measures to prevent shivering as well as evidence-based interventions to manage shivering during fever, aggressive cooling, and postoperative recovery. Detailed information is presented on assessment and documentation of the extent and severity of shivering.

The intestine plays a central role in the pathophysiology of critical illness and is frequently called the "motor" of the systemic inflammatory response. Perturbations to the intestinal barrier can lead to distant organ damage and multiple organ failure. Therefore, identifying ways to preserve intestinal integrity may be of paramount importance. Growth factors and other peptides have emerged as potential tools for modulation of intestinal inflammation and repair due to their roles in cellular proliferation, differentiation, migration, and survival. This review examines the involvement of growth factors and other peptides in intestinal epithelial repair during critical illness and their potential use as therapeutic targets.

Probiotics are living microorganisms which have demonstrated many benefits in prevention, mitigation, and treatment of various disease states in critically ill populations. These diseases include antibiotic-associated diarrhea, Clostridium difficile diarrhea, ventilator-associated pneumonia, clearance of vancomycin-resistant enterococci from the GI tract, pancreatitis, liver transplant, major abdominal surgery, and trauma. However, their use has been severely limited due to a variety of factors including a general naïveté within the physician community, lack of regulation, and safety concerns. This article focuses on uses for probiotics in prevention and treatment, addresses current concerns regarding their use as well as proposing a protocol for safe use of probiotics in the critically ill patient.

Patients with advanced illness often spend time in an ICU, while nearly one-third of patients with advanced cancer who receive Medicare die in hospitals, often with failed ICU care. For most, death occurs following the withdrawal or withholding of life-sustaining treatments. The integration of palliative care is essential for high-quality critical care. Although palliative care specialists are becoming increasingly available, intensivists and other physicians are also expected to provide basic palliative care, including symptom treatment and communication about goals of care. Patients who are critically ill are often unable to make decisions about their care. In these situations, physicians must meet with family members or other surrogates to determine appropriate medical treatments. These meetings require clinical expertise to ensure that patient values are explored for medical decision making about therapeutic options, including palliative care. Meetings with families take time. Issues related to the disease process, prognosis, and treatment plan are complex, and decisions about the use or limitation of intensive care therapies have life-or-death implications. Inadequate reimbursement for physician services may be a barrier to the optimal delivery of high-quality palliative care, including effective communication. Appropriate documentation of time spent integrating palliative and critical care for patients who are critically ill can be consistent with the Current Procedural Terminology codes (99291 and 99292) for critical care services. The purpose of this article is to help intensivists and other providers understand the circumstances in which integration of palliative and critical care meets the definition of critical care services for billing purposes.

Patients discharged from Critical Care suffer from excessive longer term morbidity and mortality. Physical and mental health measures of quality of life show a marked and immediate fall after admission to Critical Care with some recovery over time. However, physical function is still significantly reduced at 6 months. The National Institute for Health and Care Excellence clinical guideline on rehabilitation after critical illness, identified the need for high-quality randomised controlled trials to determine the most effective rehabilitation strategy for critically ill patients at risk of critical illness-associated physical morbidity. In response to this, we will conduct a randomised controlled trial, comparing physiotherapy aimed at early and intensive patient mobilisation with routine care. We hypothesise that this intervention will improve physical outcomes and the mental health and functional well-being of survivors of critical illness. 308 adult patients who have received more than 48 h of non-invasive or invasive ventilation in Critical Care will be recruited to a patient-randomised, parallel group, controlled trial, comparing two intensities of physiotherapy. Participants will be randomised to receive either standard or intensive physiotherapy for the duration of their Critical Care admission. Outcomes will be recorded on Critical Care discharge, at 3 and 6 months following initial recruitment to the study. The primary outcome measure is physical health at 6 months, as measured by the SF-36 Physical Component Summary. Secondary outcomes include assessment of mental health, activities of daily living, delirium and ventilator-free days. We will also include a health economic analysis. The trial has ethical approval from Newcastle and North Tyneside 2 Research Ethics Committee (11/NE/0206). There is a Trial Oversight Committee including an independent chair. The results of the study will be submitted for publication in peer-reviewed journals and presented at national and international scientific meetings. ISRCTN20436833.

Continuous increase of elderly patients with multimorbidity and Emergency Department (ED) overcrowding are great challenges for modern medicine. Traditional hospital organizations are often too rigid to solve them without consistently rising healthcare costs. In this paper we present a new organizational model achieved at Internal Medicine and Critical Subacute Care Unit of Parma University Hospital, Italy, a 106-bed internal medicine area organized by intensity of care and specifically dedicated to such patients. The unit is partitioned into smaller wards, each with a specific intensity level of care, including a rapid-turnover ward (mean length of stay <4 days) admitting acutely ill patients from the ED, a subacute care ward for chronic critically ill subjects and a nurse-managed ward for stable patients who have socio-economic trouble preventing discharge. A very-rapid-turnover ("come'n'go") ward has also been instituted to manage sudden ED overflows. Continuity, effectiveness, safety and appropriateness of care are guaranteed by an innovative figure called "flow manager," with skilled clinical experience and managerial attitude, and by elaboration of an early personalized discharge plan anticipating every patient's needs according to lean methodology principles. In 2012-2014, this organizational model, compared with other peer units of the hospital and of other teaching hospitals of the region, showed a better performance, efficacy and effectiveness indexes calculated on Regional Hospital Discharge Records database system, allowing a capacity to face a massive (+22 %) rise in medical admissions from the ED. Further studies are needed to validate this model from a patient outcome point of view.

The Role of Space Medicine in Management of Risk in Spaceflight

NASA Technical Reports Server (NTRS)

Clark, Jonathan B.

2001-01-01

The purpose of Space Medicine is to ensure mission success by providing quality and comprehensive health care throughout all mission phases to optimize crew health and performance and to prevent negative long-term health consequences. Space flight presents additional hazards and associated risks to crew health, performance, and safety. With an extended human presence in space it is expected that illness and injury will occur on orbit, which may present a significant threat to crew health and performance and to mission success. Maintaining crew health, safety and performance and preventing illness and injury are high priorities necessary for mission success and agency goals. Space flight health care should meet the standards of practice of evidence based clinical medicine. The function of Space Medicine is expected to meet the agency goals as stated in the 1998 NASA Strategic Plan and the priorities established by the Critical Path Roadmap Project. The Critical Path Roadmap Project is an integrated NASA cross-disciplinary strategy to assess, understand, mitigate, and manage the risks associated with long-term exposure to the space flight environment. The evidence based approach to space medicine should be standardized, objective process yielding expected results and establishing clinical practice standards while balancing individual risk with mission (programmatic) risk. The ability to methodically apply available knowledge and expertise to individual and mission health issues will ensure appropriate priorities are assigned and resources are allocated. NASA Space Medicine risk management process is a combined clinical and engineering approach. Competition for weight, power, volume, cost, and crew time must be balanced in making decisions about the care of individual crew with competing agency resources.

This study describes an approach to develop and validate a printed information brochure about chronic critical illness aimed at improving comprehension of the disease process and outcomes for patients’ families and other surrogate decision-makers. Design Investigators reviewed existing literature to identify key domains of informational needs. Content of these domains was incorporated in a draft brochure that included graphics and a glossary of terms. Clinical sensibility, balance, and emotional sensitivity of the draft brochure were tested in a series of evaluations by cohorts of experienced clinicians (n=49) and clinical content experts (n=8), with revisions after each review. Cognitive testing of the brochure was performed through interviews of 10 representative family members of chronically critically ill patients with quantitative and qualitative analysis of responses. Measurements and Main Results Clinical sensibility and balance were rated in the two most favorable categories on a 5-point scale by more than two thirds of clinicians and content experts. After review, family members described the brochure as clear and readable and recommended that the brochure be delivered to family members by clinicians, followed by a discussion of its contents. They indicated that the glossary was useful and recommended supplementation by additional lists of local resources. After reading the brochure, their prognostic estimates became more consistent with actual outcomes. Conclusions We have developed and validated a printed information brochure that may improve family comprehension of chronic critical illness and its outcomes. The structured process that is described can serve as a template for the development of other information aids for use with seriously ill populations. PMID:21926610

Extracorporeal Life Support in Critically Ill Adults

2014-01-01

Extracorporeal life support (ECLS) has become increasingly popular as a salvage strategy for critically ill adults. Major advances in technology and the severe acute respiratory distress syndrome that characterized the 2009 influenza A(H1N1) pandemic have stimulated renewed interest in the use of venovenous extracorporeal membrane oxygenation (ECMO) and extracorporeal carbon dioxide removal to support the respiratory system. Theoretical advantages of ECLS for respiratory failure include the ability to rest the lungs by avoiding injurious mechanical ventilator settings and the potential to facilitate early mobilization, which may be advantageous for bridging to recovery or to lung transplantation. The use of venoarterial ECMO has been expanded and applied to critically ill adults with hemodynamic compromise from a variety of etiologies, beyond postcardiotomy failure. Although technology and general care of the ECLS patient have evolved, ECLS is not without potentially serious complications and remains unproven as a treatment modality. The therapy is now being tested in clinical trials, although numerous questions remain about the application of ECLS and its impact on outcomes in critically ill adults. PMID:25046529

Update: Assessment of gastric pH in the critically ill.

PubMed

Neill, K M; Rice, K T; Ahern, H L

1998-04-27

The purpose of this manuscript is to update a review of the measurement of intraluminal gastric pH in the critically ill. Intraluminal gastric pH is readily measured by aspirates tested with litmus paper or a nasogastric tube with an antimony or glass electrode tip. Significant variations of intragastric pH have been shown in different stomach locations. Significant variations in the accuracy of pH readings have also been demonstrated. Prophylactic therapy in the critically ill is aimed at maintaining a gastric pH greater than 4.0 by drug therapy that 1) neutralizes acid, 2) interrupts the signal to produce acid, 3) reduces the amount of acid produced, or 4) enhances the mucosal barrier of the stomach lining. The critically ill patients at risk of respiratory failure or coagulopathy are the patients most at risk of gastrointestinal bleeding and are, therefore, the ones most likely to benefit from prophylactic therapy. Multiple pH readings are more reliable indicators of gastric pH than are individual readings. Continuous prophylaxis is more effective than intermittent.

Chloride toxicity in critically ill patients: What's the evidence?

Crystalloids have become the fluid of choice in critically ill patients and in the operating room both for fluid resuscitation and fluid maintenance. Among crystalloids, NaCl 0.9% has been the most widely used fluid. However, emerging evidence suggests that administration of 0.9% saline could be harmful mainly through high chloride content and that the use of fluid with low chloride content may be preferable in major surgery and intensive care patients. Administration of NaCl 0.9% is the leading cause of metabolic hyperchloraemic acidosis in critically ill patients and side effects might target coagulation, renal function, and ultimately increase mortality. More balanced solutions therefore may be used especially when large amount of fluids are administered in high-risk patients. In this review, we discuss physiological background favouring the use of balanced solutions as well as the most recent clinical data regarding the use of crystalloid solutions in critically ill patients and patients undergoing major surgery.

Protein nutrition and exercise survival kit for critically ill.

PubMed

Weijs, Peter J M

2017-08-01

Protein delivery as well as exercise of critically ill in clinical practice is still a highly debated issue. Here we discuss only the most recent updates in the literature concerning protein nutrition and exercise of the critically ill. By lack of randomized controlled trial (RCTs) in protein nutrition we discuss four post-hoc analyses of nutrition studies and one experimental study in mice. Studies mainly confirm some insights that protein and energy effects are separate and that the trajectory of the patient in the ICU might change these effects. Exercise has been studied much more extensively with RCTs in the last year, although also here the differences between patient groups and timing of intervention might play their roles. Overall the effects of protein nutrition and exercise appear to be beneficial. However, studies into the differential effects of protein nutrition and/or exercise, and optimization of their combined use, have not been performed yet and are on the research agenda. Optimal protein nutrition, optimal exercise intervention as well as the optimal combination of nutrition, and exercise may help to improve long-term physical performance outcome in the critically ill patients.

Objective Stress induced hyperglycemia occurs in critically ill patients who have normal glucose tolerance following resolution of their acute illness. The objective was to evaluate the association between stress induced hyperglycemia and incident diabetes in survivors of critical illness. Design Retrospective cohort study. Setting All adult patients surviving admission to a public hospital intensive care unit (ICU) in South Australia between 2004 and 2011. Patients Stress induced hyperglycemia was defined as a blood glucose ≥ 11.1 mmol/L (200 mg/dL) within 24 hours of ICU admission. Prevalent diabetes was identified through ICD-10 coding or prior registration with the Australian National Diabetes Service Scheme (NDSS). Incident diabetes was identified as NDSS registration beyond 30 days after hospital discharge until July 2015. The predicted risk of developing diabetes was described as sub-hazard ratios using competing risk regression. Survival was assessed using Cox proportional hazards regression. Main Results Stress induced hyperglycemia was identified in 2,883 (17%) of 17,074 patients without diabetes. The incidence of type 2 diabetes following critical illness was 4.8% (821 of 17,074). The risk of diabetes in patients with stress induced hyperglycemia was approximately double that of those without (HR 1.91 (95% CI 1.62, 2.26), p<0.001) and was sustained regardless of age or severity of illness. Conclusions Stress induced hyperglycemia identifies patients at subsequent risk of incident diabetes. PMID:27824898

Critical illness among adults with cystic fibrosis in Texas, 2004-2013: Patterns of ICU utilization, characteristics, and outcomes.

Available reports on critically ill adults with cystic fibrosis (CF) suggest improving short-term outcomes. However, there is marked heterogeneity in reported findings, with studies mostly based on single-centered data, limiting generalizability. We sought to examine population-level patterns of demand for critical care resources, and the characteristics, resource utilization, and outcomes of ICU-managed adults with CF. We used the Texas Inpatient Public Use Data File to identify ICU admissions with CF aged ≥18 years in Texas between 2004-2013. We examined ICU utilization at population level (using CF Foundation annual reports) and, among ICU admissions, socio-demographic characteristics, burden of comorbidities, organ failure, life-support utilization and hospital disposition. Linear regression and multilevel logistic regression were used to examine temporal trends and predictors of short-term mortality (hospital death and discharge to hospice), respectively. Of 9,579 hospitalizations of adults with CF, 1,249 (13%) were admitted to ICU. The incidence of ICU admission among adults with CF in Texas increased between 2004-2005 and 2012-2013 from 16.7 to 19.2 per 100 person-years (p = 0.0181), with ICU admissions aged ≥30 years accounting for 80.3% of the change. Among ICU admissions the following changes were noted between 2004-2005 and 2012-2013: any organ failure 30.2% vs. 56.3% (p = 0.0004), mechanical ventilation 11.5% vs. 19.2% (p = 0.0216), and hemodialysis 1.0% vs. 8.1% (p = 0.0007). Short-term mortality for the whole cohort and for those with mechanical ventilation was 11.4% and 41.8%, respectively, with corresponding home discharge among survivors 84% and 62.1%, respectively. Key predictors (adjusted odds ratios [aOR (95% CI)]) of short-term mortality included age ≥45 years (2.051 [1.231-3.415]), female gender (1.907 [1.237-2.941]), and mechanical ventilation (7.982 [5.001-12.739]). Adults with CF had high and rising population-level burden of critical illness. Although ICU admissions were increasingly older and sicker, the majority survived hospitalization, with most discharged home, supporting short-term benefits of critical care in the present cohort.

The chronically critically ill have survived acute critical illness but require prolonged mechanical ventilation. These patients are frequently transferred from acute care to long-term acute care hospitals (LTACHs) for prolonged recovery, yet many suffer setbacks requiring readmission to acute care. The patient's relatively improved condition while at the LTACH might be an opportunity for communication regarding care goals; however, there have been no prior studies of the feasibility of such conversations in the LTACH. To determine the feasibility, acceptability, and potential usefulness of conversations about serious illness with chronic critical illness patients or their surrogate decision makers after LTACH admission. We adapted an existing conversation guide for use in chronically critically ill (defined by tracheotomy for prolonged ventilation) LTACH patients or their surrogates to explore views about quality of life, understanding of medical conditions, expectations, and planning for setbacks. These conversations were conducted by one interviewer and summarized for the patients' clinicians. We surveyed patients, surrogates, and clinicians to assess acceptability. A total of 70 subjects were approached and 50 (71%) were enrolled, including 30 patients and 20 surrogates. The median duration of the conversation was 14 minutes 45 seconds [IQR 12:46, 19]. The presence of ongoing mechanical ventilation did not lead to longer conversations; in fact, conversations with patients were shorter than those with surrogates. The majority of subjects (81%) described the conversation as worthwhile. The majority of clinicians (73%) reported that the conversation offered a new and significant understanding of the patient's preferences if a setback were to occur. Conversations about serious illness care goals can be accomplished in a relatively short period of time, are acceptable to chronically critically ill patients and their surrogate decision makers in the LTACH, and are perceived as worthwhile by patients, surrogates, and clinicians.

The aim of this research study was to examine the relationship between 4 sources of social support (support for the adolescent from family, support for the adolescent from friends, support for the caregiver from another adult, and support to the family from the health care provider) and adolescents' diabetes outcomes (illness management behavior and health status) using a diverse sample of urban adolescents. One hundred forty-one adolescents with insulin-managed diabetes and their primary caregivers completed questionnaires assessing social support and illness management behavior. Glucose meters were downloaded and hemoglobin A1c assays were obtained. Structural equation modeling was used to test a model social support informed by social ecological theory. The results of the structural equation modeling indicated that support for the caregiver from another adult was directly and positively related to support for the adolescent from family and indirectly related to better illness management. Support for the adolescent from family was directly related to better diabetes management and, through better management, to better diabetes health. Support to the family from the health care provider was not related to support for the adolescent and support to the adolescent from friends was not related to illness management, as hypothesized. This study identifies a novel target for social support intervention to improve adolescents' illness management behavior-the caregivers of adolescents with diabetes. By enhancing the social support caregivers receive from other adults in their lives, caregivers' ability to support their adolescent children with diabetes might also be improved which, in turn, improves adolescents' illness outcomes.

The Sick and the Weak: Neuropathies/Myopathies in the Critically Ill

Critical illness polyneuropathies (CIP) and myopathies (CIM) are common complications of critical illness. Several weakness syndromes are summarized under the term intensive care unit-acquired weakness (ICUAW). We propose a classification of different ICUAW forms (CIM, CIP, sepsis-induced, steroid-denervation myopathy) and pathophysiological mechanisms from clinical and animal model data. Triggers include sepsis, mechanical ventilation, muscle unloading, steroid treatment, or denervation. Some ICUAW forms require stringent diagnostic features; CIM is marked by membrane hypoexcitability, severe atrophy, preferential myosin loss, ultrastructural alterations, and inadequate autophagy activation while myopathies in pure sepsis do not reproduce marked myosin loss. Reduced membrane excitability results from depolarization and ion channel dysfunction. Mitochondrial dysfunction contributes to energy-dependent processes. Ubiquitin proteasome and calpain activation trigger muscle proteolysis and atrophy while protein synthesis is impaired. Myosin loss is more pronounced than actin loss in CIM. Protein quality control is altered by inadequate autophagy. Ca2+ dysregulation is present through altered Ca2+ homeostasis. We highlight clinical hallmarks, trigger factors, and potential mechanisms from human studies and animal models that allow separation of risk factors that may trigger distinct mechanisms contributing to weakness. During critical illness, altered inflammatory (cytokines) and metabolic pathways deteriorate muscle function. ICUAW prevention/treatment is limited, e.g., tight glycemic control, delaying nutrition, and early mobilization. Future challenges include identification of primary/secondary events during the time course of critical illness, the interplay between membrane excitability, bioenergetic failure and differential proteolysis, and finding new therapeutic targets by help of tailored animal models.

 Patients with end stage liver disease may become critically ill prior to LT requiring admission to the intensive care unit (ICU). The high acuity patients may be thought too ill to transplant; however, often LT is the only therapeutic option. Choosing the correct liver allograft for these patients is often difficult and it is imperative that the allograft work immediately. Donation after cardiac death (DCD) donors provide an important source of livers, however, DCD graft allocation remains a controversial topic, in critically ill patients. Between January 2003-December 2008, 1215 LTs were performed: 85 patients at the time of LT were in the ICU. Twelve patients received DCD grafts and 73 received donation after brain dead (DBD) grafts. After retransplant cases and multiorgan transplants were excluded, 8 recipients of DCD grafts and 42 recipients of DBD grafts were included in this study. Post-transplant outcomes of DCD and DBD liver grafts were compared. While there were differences in graft and survival between DCD and DBD groups at 4 month and 1 year time points, the differences did not reach statistical significance. The graft and patient survival rates were similar among the groups at 3-year time point. There is need for other large liver transplant programs to report their outcomes using liver grafts from DCD and DBD donors. We believe that the experience of the surgical, medical and critical care team is important for successfully using DCD grafts for critically ill patients.

Designing drug regimens for special intensive care unit populations

Erstad, Brian L

2015-01-01

This review is intended to help clinicians design drug regimens for special populations of critically ill patients with extremes of body size, habitus and composition that make drug choice or dosing particularly challenging due to the lack of high-level evidence on which to make well-informed clinical decisions. The data sources included a literature search of MEDLINE and EMBASE with reviews of reference lists of retrieved articles. Abstracts of original research investigations and review papers were reviewed for their relevance to drug choice or dosing in the following special critically ill populations: patients with more severe forms of bodyweight or height, patients with amputations or missing limbs, pregnant patients, and patients undergoing extracorporeal membrane oxygenation or plasma exchange. Relevant papers were retrieved and evaluated, and their associated reference lists were reviewed for citations that may have been missed through the electronic search strategy. Relevant original research investigations and review papers that could be used to formulate general principles for drug choice or dosing in special populations of critically ill patients were extracted. Randomized studies with clinically relevant endpoints were not available for performing quantitative analyses. Critically ill patients with changes in body size, habitus and composition require special consideration when designing medication regimens, but there is a paucity of literature on which to make drug-specific, high-level evidence-based recommendations. Based on the evidence that is available, general recommendations are provided for drug choice or dosing in special critically ill populations. PMID:25938029

The experience of sleep deprivation in intensive care patients: findings from a larger hermeneutic phenomenological study.

Sleep deprivation in critically ill patients has been well documented for more than 30 years. Despite the large body of literature, sleep deprivation remains a significant concern in critically ill patients in intensive care unit (ICU). This paper discusses sleep deprivation in critically ill patients as one of the main findings from a study that explored the lived experiences of critically ill patients in ICU with daily sedation interruption (DSI). Twelve participants aged between 20 and 76 years with an ICU stay ranging from three to 36 days were recruited from a 16 bed ICU in a large regional referral hospital in New South Wales (NSW), Australia. Participants were intubated, mechanically ventilated and subjected to daily sedation interruption during their critical illness in ICU. In-depth face to face interviews with the participants were conducted at two weeks after discharge from ICU. A second interview was conducted with eight participants six to eleven months later. Interviews were audio taped and transcribed. Data were analysed thematically. "Longing for sleep" and "being tormented by nightmares" capture the experiences and concerns of some of the participants. The findings suggest a need for models of care that seek to support restful sleep and prevent or alleviate sleep deprivation and nightmares. These models of care need to promote both quality and quantity of sleep in and beyond ICU and identify patients suffering from sleep deprivation to make appropriate referrals for treatment and support.

Purpose To determine how patient, healthcare system and study-specific factors influence reported mortality associated with critical illness during the 2009–2010 Influenza A (H1N1) pandemic. Methods Systematic review with meta-regression of studies reporting on mortality associated with critical illness during the 2009–2010 Influenza A (H1N1) pandemic. Data Sources Medline, Embase, LiLACs and African Index Medicus to June 2009-March 2016. Results 226 studies from 50 countries met our inclusion criteria. Mortality associated with H1N1-related critical illness was 31% (95% CI 28–34). Reported mortality was highest in South Asia (61% [95% CI 50–71]) and Sub-Saharan Africa (53% [95% CI 29–75]), in comparison to Western Europe (25% [95% CI 22–30]), North America (25% [95% CI 22–27]) and Australia (15% [95% CI 13–18]) (P<0.0001). High income economies had significantly lower reported mortality compared to upper middle income economies and lower middle income economies respectively (P<0.0001). Mortality for the first wave was non-significantly higher than wave two (P = 0.66). There was substantial variability in reported mortality among the specific subgroups of patients: unselected critically ill adults (27% [95% CI 24–30]), acute respiratory distress syndrome (37% [95% CI 32–44]), acute kidney injury (44% [95% CI 26–64]), and critically ill pregnant patients (10% [95% CI 5–19]). Conclusion Reported mortality for outbreaks and pandemics may vary substantially depending upon selected patient characteristics, the number of patients described, and the region and economic status of the outbreak location. Outcomes from a relatively small number of patients from specific regions may lead to biased estimates of outcomes on a global scale. PMID:27170999

The complexity of the cases of critically ill polytrauma patients is given by both the primary, as well as the secondary, post-traumatic injuries. The severe injuries of organ systems, the major biochemical and physiological disequilibrium, and the molecular chaos lead to a high rate of morbidity and mortality in this type of patient. The 'gold goal' in the intensive therapy of such patients resides in the continuous evaluation and monitoring of their clinical status. Moreover, optimizing the therapy based on the expression of certain biomarkers with high specificity and sensitivity is extremely important because of the clinical course of the critically ill polytrauma patient. In this paper we wish to summarize the recent studies of biomarkers useful for the intensive care unit (ICU) physician. For this study the available literature on specific databases such as PubMed and Scopus was thoroughly analyzed. Each article was carefully reviewed and useful information for this study extracted. The keywords used to select the relevant articles were "sepsis biomarker", "traumatic brain injury biomarker" "spinal cord injury biomarker", "inflammation biomarker", "microRNAs biomarker", "trauma biomarker", and "critically ill patients". For this study to be carried out 556 original type articles were analyzed, as well as case reports and reviews. For this review, 89 articles with relevant topics for the present paper were selected. The critically ill polytrauma patient, because of the clinical complexity the case presents with, needs a series of evaluations and specific monitoring. Recent studies show a series of either tissue-specific or circulating biomarkers that are useful in the clinical status evaluation of these patients. The biomarkers existing today, with regard to the critically ill polytrauma patient, can bring a significant contribution to increasing the survival rate, by adapting the therapy according to their expressions. Nevertheless, the necessity remains to research new non-invasive diagnostic methods that present with higher specificity and selectivity.

Poor functional status is common after critical illness, and can adversely impact the abilities of intensive care unit (ICU) survivors to live independently. Instrumental activities of daily living (IADL), which encompass complex tasks necessary for independent living, are a particularly important component of post-ICU functional outcome. To conduct a systematic review of studies evaluating IADLs in survivors of critical illness. We searched PubMed, CINAHL, Cochrane Library, SCOPUS, and Web of Science for all relevant English-language studies published through December 31, 2016. Additional articles were identified from personal files and reference lists of eligible studies. Two trained researchers independently reviewed titles and abstracts, and potentially eligible full text studies. Eligible studies included those enrolling adult ICU survivors with IADL assessments, using a validated instrument. We excluded studies involving specific ICU patient populations, specialty ICUs, those enrolling fewer than 10 patients, and those that were not peer-reviewed. Variables related to IADLs were reported using the Patient Reported Outcomes Measurement Information System (PROMIS). Thirty of 991 articles from our literature search met inclusion criteria, and 23 additional articles were identified from review of reference lists and personal files. Sixteen studies (30%) published between 1999 and 2016 met eligibility criteria and were included in the review. Study definitions of impairment in IADLs were highly variable, as were reported rates of pre-ICU IADL dependencies (7-85% of patients). Eleven studies (69%) found that survivors of critical illness had new or worsening IADL dependencies. In three of four longitudinal studies, survivors with IADL dependencies decreased over the follow-up period. Across multiple studies, no risk factors were consistently associated with IADL dependency. Survivors of critical illness commonly experience new or worsening IADL dependency that may improve over time. As part of ongoing efforts to understand and improve functional status in ICU survivors, future research must focus on risk factors for IADL dependencies and interventions to improve these cognitive and physical dependencies after critical illness.

Chronic critical illness is a devastating syndrome for which treatment offers limited clinical benefit but imposes heavy burdens on patients, families, clinicians, and the health care system. We studied the availability of advance directives and appropriate surrogates to guide decisions about life-sustaining treatment for the chronically critically ill and the extent and timing of treatment limitation. Prospective cohort study. Respiratory Care Unit (RCU) in a large, tertiary, urban, university-affiliated, hospital. Two hundred three chronically critically ill adults transferred to RCU after tracheotomy for failure to wean from mechanical ventilation in the intensive care unit. None. We interviewed RCU caregivers and reviewed patient records to identify proxy appointments, living wills, or oral statements of treatment preferences, resuscitation directives, and withholding/withdrawal of mechanical ventilation, nutrition, hydration, renal replacement and vasopressors. Forty-three of 203 patients (21.2%) appointed a proxy and 33 (16.2%) expressed preferences in advance directives. Do not resuscitate directives were given for 71 patients (35.0%). Treatment was limited for 39 patients (19.2%). Variables significantly associated with treatment limitation were proxy appointment prior to study entry (time of tracheotomy/RCU transfer) (odds ratio = 6.7, 95% confidence interval [CI], 2.3-20.0, p = 0.0006) and palliative care consultation in the RCU (OR = 40.9, 95% CI, 13.1-127.4, p < 0.0001). Median (interquartile range) time to first treatment limitation was 39 (31.0-45.0) days after hospital admission and 13 (8.0-29.0) days after RCU admission. For patients dying after treatment limitation, median time from first limitation to death ranged from 3 days for mechanical ventilation and hydration to 7 days for renal replacement. Most chronically critically ill patients fail to designate a surrogate decision-maker or express preferences regarding life-sustaining treatments. Despite burdensome symptoms and poor outcomes, limitation of such treatments was rare and occurred late, when patients were near death. Opportunities exist to improve communication and decision-making in chronic critical illness.

Introduction Acute kidney injury (AKI) affects more than 50% of critically ill patients. The formation of calcitriol, the active vitamin D metabolite, from the main inactive circulating form, 25-hydroxyvitamin D (25(OH)D), occurs primarily in the proximal renal tubules. This results in a theoretical basis for reduction in levels of calcitriol over the course of an AKI. Vitamin D deficiency is highly prevalent in critically ill adults, and has been associated with increased rates of sepsis, longer hospital stays and increased mortality. The primary objective of this study is to perform serial measurements of 25(OH)D and calcitriol (1,25(OH)2D), as well as parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) levels, in critically ill adult patients with and without AKI, and to determine whether patients with AKI have significantly lower vitamin D metabolite concentrations. The secondary objectives are to describe dynamic changes in vitamin D metabolites, PTH and FGF23 during critical illness; to compare vitamin D metabolite concentrations in patients with AKI with and without renal replacement therapy; and to investigate whether there is an association between vitamin D status and outcomes. Methods and analysis 230 general adult intensive care patients will be recruited. The AKI arm will include 115 critically ill patients with AKI Kidney Disease Improving Global Outcome stage II or stage III. The comparison group will include 115 patients who require cardiovascular or respiratory support, but who do not have AKI. Serial measurements of vitamin D metabolites and associated hormones will be taken on prespecified days. Patients will be recruited from two large teaching Trusts in England. Data will be analysed using standard statistical methods. Ethics and dissemination Ethical approval was obtained. Upon completion, the study team will submit the study report for publication in a peer-reviewed scientific journal and for conference presentation. Trial registration number NCT02869919; Pre-results.

An observational study of critically ill children with influenza A/pH1N1 infection in pediatric intensive care units (PICUs). Nine Canadian PICUs. A total of 57 patients admitted to PICUs between April 16, 2009 and August 15, 2009. None. Characteristics of critically ill children with influenza A/pH1N1 infection were recorded. Confirmed intensive care unit cases were compared with a national surveillance database containing all hospitalized pediatric patients with influenza A/pH1N1 infection. Risk factors were assessed with a Cox proportional hazard model. The PICU cohort and national surveillance data were compared, using chi-square tests. Fifty-seven children were admitted to the PICU for community-acquired influenza A/pH1N1 infection. One or more chronic comorbid illnesses were observed in 70.2% of patients, and 24.6% of patients were aboriginal. Mechanical ventilation was used in 68% of children, 20 children (35.1%) had acute lung injury on the first day of admission, and the median duration of ventilation was 6 days (range, 0-67 days). The PICU mortality rate was 7% (4 of 57 patients). When compared with nonintensive care unit hospitalized children, PICU children were more likely to have a chronic medical condition (relative risk, 1.73); aboriginal ethnicity was not a risk factor of intensive care unit admission. During the first outbreak of influenza A/pH1N1 infection, when the population was naïve to this novel virus, severe illness was common among children with underlying chronic conditions and aboriginal children. Influenza A/pH1N1-related critical illness in children was associated with severe hypoxemic respiratory failure and prolonged mechanical ventilation. However, this higher rate and severity of respiratory illness did not result in an increased mortality when compared with seasonal influenza.

Introduction Glutamine supplementation is supposed to reduce mortality and nosocomial infections in critically ill patients. However, the recently published reducing deaths due to oxidative stress (REDOX) trials did not provide evidence supporting this. This study investigated the impact of glutamine-supplemented nutrition on the outcomes of critically ill patients using a meta-analysis. Methods We searched for and gathered data from the Cochrane Central Register of Controlled Trials, MEDLINE, Elsevier, Web of Science and ClinicalTrials.gov databases reporting the effects of glutamine supplementation on outcomes in critically ill patients. We produced subgroup analyses of the trials according to specific patient populations, modes of nutrition and glutamine dosages. Results Among 823 related articles, eighteen Randomized Controlled Trials (RCTs) met all inclusion criteria. Mortality events among 3,383 patients were reported in 17 RCTs. Mortality showed no significant difference between glutamine group and control group. In the high dosage subgroup (above 0.5 g/kg/d), the mortality rate in the glutamine group was significantly higher than that of the control group (relative risk (RR) 1.18; 95% confidence interval (CI), 1.02 to 1.38; P = 0.03). In 15 trials, which included a total of 2,862 patients, glutamine supplementation reportedly affected the incidence of nosocomial infections in the critically ill patients observed. The incidence of nosocomial infections in the glutamine group was significantly lower than that of the control group (RR 0.85; 95% CI, 0.74 to 0.97; P = 0.02). In the surgical ICU subgroup, glutamine supplementation statistically reduced the rate of nosocomial infections (RR 0.70; 95% CI, 0.52 to 0.94; P = 0.04). In the parental nutrition subgroup, glutamine supplementation statistically reduced the rate of nosocomial infections (RR 0.83; 95% CI, 0.70 to 0.98; P = 0.03). The length of hospital stay was reported in 14 trials, in which a total of 2,777 patients were enrolled; however, the patient length of stay was not affected by glutamine supplementation. Conclusions Glutamine supplementation conferred no overall mortality and length of hospital stay benefit in critically ill patients. However, this therapy reduced nosocomial infections among critically ill patients, which differed according to patient populations, modes of nutrition and glutamine dosages. PMID:24401636

Objective Serious mental illness and type II diabetes mellitus have a high comorbidity, and both have a higher prevalence of anxiety disorders compared to the general population. Targeted Training in Illness Management is a group-based self-management training approach which targets serious mental illness and type II diabetes mellitus concurrently. This analysis examines data from a randomized controlled trial of Targeted Training in Illness Management intervention to examine the impact of comorbid anxiety on baseline psychiatric symptomatology and diabetic control, and on longitudinal treatment outcomes. Methods We conducted secondary analyses on data from a prospective, 60-week, randomized controlled trial testing Targeted Training in Illness Management versus treatment as usual in 200 individuals with serious mental illness and diabetes. Primary outcomes included measures related to serious mental illness symptoms, functional status, general health status, and diabetes control. Measures were compared between those participants with anxiety disorders versus those without anxiety at baseline as well as over time using linear mixed effects analyses. Results Forty seven percent of the participants had one or more anxiety disorders. At baseline, those with an anxiety diagnosis had higher illness severity, depressive, and other psychiatric symptomatology and disability. Diabetic control (HbA1c) was not significantly different at baseline. In the longitudinal analyses, no significant mean slope differences over time (group-by-time interaction effect) between those with anxiety diagnoses and those without in treatment as usual group were found for primary outcomes. Within the Targeted Training in Illness Management arm, those with anxiety disorders had significantly greater improvement in mental health functioning. Those with anxiety comorbidity in the Targeted Training in Illness Management group demonstrated significantly lower HbA1c levels compared to no anxiety comorbidity and also demonstrated a greater improvement in HbA1c over the first 30 weeks compared to those without anxiety comorbidity. Conclusion Comorbid anxiety in serious mental illness and type II diabetes mellitus population is associated with increased psychiatric symptomatology and greater disability. Individuals from this population appear to experience greater improvement in functioning from baseline with the Targeted Training in Illness Management intervention. Anxiety comorbidity in the serious mental illness and type II diabetes mellitus population does not appear to have a negative impact on diabetic control. These complex relationships need further study. Clinical Trials Registration ClinicalTrials.gov: Improving outcomes for individuals with serious mental illness and diabetes (NCT01410357).

Acute diarrhoeal diseases remain a leading cause of global morbidity and mortality particularly among young children in resource-limited countries. Recent large studies utilizing case–control design, prospective sampling and more sensitive and broad diagnostic techniques have shed light on particular pathogens of importance and highlighted the previously under recognized impact of these infections on post-acute illness mortality and growth. Vaccination, particularly against rotavirus, has emerged as a key effective means of preventing significant morbidity and mortality from childhood diarrhoeal disease. Other candidate vaccines against leading diarrhoeal pathogens, such as enterotoxigenic Escherichia coli and Shigella spp., also hold significant promise in further ameliorating the burden of enteric infections in children. Large studies are also currently underway evaluating novel and potential easy-to-implement water, sanitation and hygiene (WASH) preventive strategies. Given the ongoing global burden of this illness, the paucity of new advances in case management over the last several decades remains a challenge. The increasing recognition of post-acute illness mortality and growth impairment has highlighted the need for interventions that go beyond management of dehydration and electrolyte disturbances. The few trials of novel promising interventions such as probiotics have mainly been conducted in high-income settings. Trials of antimicrobials have also been primarily conducted in high-income settings or in travellers from high-income settings. Bloody diarrhoea has been shown to be a poor marker of potentially treatable bacterial enteritis, and rising antimicrobial resistance has also made empiric antimicrobial therapy more challenging in many settings. Novel effective and sustainable interventions and diagnostic strategies are clearly needed to help improve case management. Diarrhoeal disease and other enteric infections remain an unmet challenge in global child health. Most promising recent developments have been focused around preventive measures, in particular vaccination. Further advances in prevention and case management including the possible use of targeted antimicrobial treatment are also required to fully address this critical burden on child health and human potential.

Advanced technology has enhanced our ability to diagnose and treat critically ill patients, thereby assisting in prolonging life for many. However, its high cost has been prohibitive, and it may impose more burdens than benefits on some patients. Although technological advances have accelerated social change, many have also fuelled legal and ethical concerns. Consequently, the rationale for the use of advanced technology in the care of critically ill patients should be clear and ethically justified.

In this review, we seek to highlight how critical illness and critical care affect longer-term outcomes, to underline the contribution of ICU delirium to cognitive dysfunction several months after ICU discharge, to give new insights into ICU acquired weakness, to emphasize the importance of value-based healthcare, and to delineate the elements of family-centered care. This consensus of 29 also provides a perspective and a research agenda about post-ICU recovery.

The purpose of this study was to construct and test a hypothetical model of self-management in patients with hemodialysis based on the Self-Regulation Model and resource-coping perspective. Data were collected from 215 adults receiving hemodialysis in 17 local clinics and one tertiary hospital in 2016. The Hemodialysis Self-management Instrument, the Revised Illness Perception Questionnaire, Herth Hope Index and Multidimensional Scale of Perceived Social Support were used. The exogenous variable was social context; the endogenous variables were cognitive illness representation, hope, self-management behavior, and illness outcome. For data analysis, descriptive statistics, Pearson correlation analysis, factor analysis, and structural equation modeling were performed. The hypothetical model with six paths showed a good fitness to the empirical data: GFI=.96, AGFI=.90, CFI=.95, RMSEA=.08, SRMR=.04. The factors that had an influence on self-management behavior were social context (β=.84), hope and cognitive illness representation (β=.37 and β=.27) explaining 92.4% of the variance. Self-management behavior mediated the relationship between psychosocial coping resources and illness outcome. This research specifies a more complete spectrum of the self-management process. It is important to recognize the array of clinical resources available to support patients' self-management. Healthcare providers can facilitate self-management through collaborative care and understanding the ideas and emotions that each patient has about the illness, and ultimately improve the health outcomes. This framework can be used to guide self-management intervention development and assure effective clinical assessment. © 2017 Korean Society of Nursing Science

We describe futures of ICU admission, demographic characteristics, treatment and outcome for critically ill patients with laboratory-confirmed and suspected infection with the H1N1 virus admitted to the three different critical care departments in Turkey. Retrospective study of critically ill patients with 2009 influenza A(H1N1) at ICU. Demographic data, symptoms, comorbid conditions, and clinical outcomes were collected using a case report form. Critical illness occurred in 61 patients admitted to an ICU with confirmed (n=45) or probable and suspected 2009 influenza A(H1N1). Patients were young (mean, 41.5 years), were female (54%). Fifty-six patients, required mechanical ventilation (14 invasive, 27 noninvasive, 15 both) during the course of ICU. On admission, mean APACHE II score was 18.7±6.3 and median PaO(2)/FIO(2) was 127.9±70.4. 31 patients (50.8%) was die. There were no significant differences in baseline PaO(2)/FIO(2 )and ventilation strategies between survivors and nonsurvivors. Patients who survived were more likely to have NIMV use at the time of admission to the ICU. Critical illness from 2009 influenza A(H1N1) in ICU predominantly affects young patients with little major comorbidity and had a high case-fatality rate. NIMV could be used in 2009 influenza A (H1N1) infection-related hypoxemic respiratory failure.

The meaning of social support for the critically ill patient.

Social support has been shown to be important for the critically ill patient. However, what constitutes adequate support for these patients has not been investigated. Thus, the purpose of this qualitative study was to investigate patients' perceptions of their need for and adequacy of the social support received while they were critically ill. Thirty adult patients who were critical during some point of their stay in the intensive care unit (ICU) stay were interviewed, once stable. Interviews were tape-recorded and began with an open-ended question regarding the ICU experience. This was followed by open-ended focused questions regarding social support, such as 'Who were your greatest sources of social support while you were critically ill?' 'What did they do that was supportive or unsupportive?' Data were analyzed according to Miles and Huberman (1994). The categories that emerged were need for social support based on patient perceptions (not number of visitors), quality of support (based on perceptions of positive and negative behaviors of supporters) and lack of support. This study found that quality of support was more important than the actual number of visitors. Patients with few visitors may have felt supported, while those with numerous visitors felt unsupported. Patients who felt unsupported also were more critical of the staff and the care they received. Nurses need to individually assess patients regarding their need for support, and assist family/friends to meet these needs.

Poor adherence to the Integrated Management of Childhood Illness (IMCI) protocol reduces the potential impact on under-five morbidity and mortality. Electronic technology could improve adherence; however there are few studies demonstrating the benefits of such technology in a resource-poor settings. This study estimates the impact of electronic technology on adherence to the IMCI protocols as compared to the current paper-based protocols in Tanzania. In four districts in Tanzania, 18 clinics were randomly selected for inclusion. At each site, observers documented critical parts of the clinical assessment of children aged 2 months to 5 years. The first set of observations occurred during examination of children using paper-based IMCI (pIMCI) and the next set of observations occurred during examination using the electronic IMCI (eIMCI). Children were re-examined by an IMCI expert and the diagnoses were compared. A total of 1221 children (671 paper, 550 electronic) were observed. For all ten critical IMCI items included in both systems, adherence to the protocol was greater for eIMCI than for pIMCI. The proportion assessed under pIMCI ranged from 61% to 98% compared to 92% to 100% under eIMCI (p < 0.05 for each of the ten assessment items). Use of electronic systems improved the completeness of assessment of children with acute illness in Tanzania. With the before-after nature of the design, potential for temporal confounding is the primary limitation. However, the data collection for both phases occurred over a short period (one month) and so temporal confounding was expected to be minimal. The results suggest that the use of electronic IMCI protocols can improve the completeness and consistency of clinical assessments and future studies will examine the long-term health and health systems impact of eIMCI.
