To explore the importance, challenges, and opportunities using qualitative research to enhance development of clinical practice guidelines, using recent guidelines for family-centered care in the ICU as an example. In developing the Society of Critical Care Medicine guidelines for family-centered care in the neonatal ICU, PICU, and adult ICU, we developed an innovative adaptation of the Grading of Recommendations, Assessments, Development and Evaluations approach to explicitly incorporate qualitative research. Using Grading of Recommendations, Assessments, Development and Evaluations and the Council of Medical Specialty Societies principles, we conducted a systematic review of qualitative research to establish family-centered domains and outcomes. Thematic analyses were undertaken on study findings and used to support Population, Intervention, Comparison, Outcome question development. We identified and employed three approaches using qualitative research in these guidelines. First, previously published qualitative research was used to identify important domains for the Population, Intervention, Comparison, Outcome questions. Second, this qualitative research was used to identify and prioritize key outcomes to be evaluated. Finally, we used qualitative methods, member checking with patients and families, to validate the process and outcome of the guideline development. In this, a novel report, we provide direction for standardizing the use of qualitative evidence in future guidelines. Recommendations are made to incorporate qualitative literature review and appraisal, include qualitative methodologists in guideline taskforce teams, and develop training for evaluation of qualitative research into guideline development procedures. Effective methods of involving patients and families as members of guideline development represent opportunities for future work.

Objectives Palliative care is an interprofessional specialty as well as an approach to care by all clinicians caring for patients with serious and complex illness. Unlike hospice, palliative care is based not on prognosis but on need and is an essential component of comprehensive care for critically ill patients from the time of ICU admission. In this clinically focused article, we review evidence of opportunities to improve palliative care for critically ill adults, summarize strategies for ICU palliative care improvement, and identify resources to support implementation. Data Sources We searched the MEDLINE database from inception through January 2014. We also searched the Reference Library of The Improving Palliative Care in the ICU Project website sponsored by the National Institutes of Health and the Center to Advance Palliative Care, which is updated monthly. We hand-searched reference lists and author files. Study Selection Selected studies included all English-language articles concerning adult patients using the search terms "intensive care" or "critical care" with "palliative care," "supportive care," "end-of-life care," or "ethics." Data Extraction After examination of peer-reviewed original scientific articles, consensus statements, guidelines, and reviews resulting from our literature search, we made final selections based on author consensus. Data Synthesis Existing evidence is organized to address: 1) opportunities to alleviate physical and emotional symptoms, improve communication, and provide support for patients and families; 2) models and specific interventions for improving ICU palliative care; 3) available resources for ICU palliative care improvement; and 4) ongoing challenges and targets for future research. Key domains of ICU palliative care have been defined and operationalized as measures of quality. There is increasing recognition that effective integration of palliative care during acute and chronic critical illness may help patients and

Evidence demonstrates that providing nutritional support to intensive care unit (ICU) patients within 24 hours of ICU admission reduces mortality. However, early feeding is not universally practiced. Changing practice in complex multidisciplinary environments is difficult. Evidence supporting whether guidelines can improve ICU feeding practices and patient outcomes is contradictory. To determine whether evidence-based feeding guidelines, implemented using a multifaceted practice change strategy, improve feeding practices and reduce mortality in ICU patients. Cluster randomized trial in ICUs of 27 community and tertiary hospitals in Australia and New Zealand. Between November 2003 and May 2004, 1118 critically ill adult patients expected to remain in the ICU longer than 2 days were enrolled. All participants completed the study. Intensive care units were randomly assigned to guideline or control groups. Guideline ICUs developed an evidence-based guideline using Browman's Clinical Practice Guideline Development Cycle. A practice-change strategy composed of 18 specific interventions, leveraged by educational outreach visits, was implemented in guideline ICUs. Hospital discharge mortality. Secondary outcomes included ICU and hospital length of stay, organ dysfunction, and feeding process measures. Guideline and control ICUs enrolled 561 and 557 patients, respectively. Guideline ICUs fed patients earlier (0.75 vs 1.37 mean days to enteral nutrition start; difference, -0.62 [95% confidence interval {CI}, -0.82 to -0.36]; P < .001 and 1.04 vs 1.40 mean days to parenteral nutrition start; difference, -0.35 [95% CI, -0.61 to -0.01]; P = .04) and achieved caloric goals more often (6.10 vs 5.02 mean days per 10 fed patient-days; difference, 1.07 [95% CI, 0.12 to 2.22]; P = .03). Guideline and control ICUs did not differ with regard to hospital discharge mortality (28.9% vs 27.4%; difference, 1.4% [95% CI, -6.3% to 12.0%]; P = .75) or to hospital length of stay (24.2 vs 24

Improving value within critical care remains a priority because it represents a significant portion of health-care spending, faces high rates of adverse events, and inconsistently delivers evidence-based practices. ICU directors are increasingly required to understand all aspects of the value provided by their units to inform local improvement efforts and relate effectively to external parties. A clear understanding of the overall process of measuring quality and value as well as the strengths, limitations, and potential application of individual metrics is critical to supporting this charge. In this review, we provide a conceptual framework for understanding value metrics, describe an approach to developing a value measurement program, and summarize common metrics to characterize ICU value. We first summarize how ICU value can be represented as a function of outcomes and costs. We expand this equation and relate it to both the classic structure-process-outcome framework for quality assessment and the Institute of Medicine’s six aims of health care. We then describe how ICU leaders can develop their own value measurement process by identifying target areas, selecting appropriate measures, acquiring the necessary data, analyzing the data, and disseminating the findings. Within this measurement process, we summarize common metrics that can be used to characterize ICU value. As health care, in general, and critical care, in particular, changes and data become more available, it is increasingly important for ICU leaders to understand how to effectively acquire, evaluate, and apply data to improve the value of care provided to patients.

Very few studies focused on patients with severe infective endocarditis (IE) and multiple complications leading to Intensive Care Unit (ICU) admission. Studied primary outcomes depended on the series and multiple prognostic factors have been identified. Our goal was to determinate characteristics of patients, in-hospital mortality and independent prognostic factors in an overall population of patients admitted to ICU for a left-sided, definite, active and severe IE. Retrospective study performed in 9 ICUs during an 11-year period. Data of 248 patients (mean age = 62.4 ± 13.3 years; 63.7 % male) were studied. Native and prosthetic valves were involved in 195 and 53 patients, respectively. Causative pathogens, identified in 225 patients, were mainly streptococci (45.6 %) and staphylococci (43.4 %). On ICU admission, 127 patients exhibited extra-cardiac involvement. Ninety-five patients had one or more neurological complications, as followed: ischemic stroke (n = 66), cerebral hemorrhage (n = 31), meningitis (n = 16), brain abscess (n = 16), and intracranial mycotic aneurysm (n = 10). Criteria prompting to cardiac surgery appeared during ICU stay for 186 patients and between ICU and hospital discharges in 5 patients. Due to contra-indications, surgery required by IE was only performed during hospitalization in 125 patients. Moreover, surgery was considered adequate according to usual guidelines in 76 of 191 patients with indication(s) of valvular surgery: for patients with surgical procedure considered as emergency (n = 69), 17 surgical procedures underwent within the first 24 h following indication; for patients with urgent surgical indication (n = 102), surgery was performed during the first week following indication in 40 patients; finally, elective surgery (n = 20) was performed for 19 patients. During hospitalization, 103 (41.5 %) patients died. Four independent prognostic factors were identified: SAPS II > 35 (AOR = 2.604; 95 % CI

BACKGROUND/OBJECTIVE: Guidelines for the management of patients with nonvariceal upper gastrointestinal bleeding (NVUGIB) are inconsistently applied by health care providers, potentially resulting in suboptimal care and patient outcomes. A needs assessment was performed to assess health care providers’ barriers to the implementation of these guidelines in Canada. METHODS: Semistructured telephone interviews were conducted by trained research personnel with 22 selectively sampled health care professionals actively treating and managing NVUGIB patients, including emergency room physicians (ER), intensivists (ICU), gastroenterologists (GI), gastroenterology nurses and hospital administrators. Participants were chosen from a representative sample of six Canadian community- and academic-based hospitals that participated in a national Canadian audit on the management of NVUGIB. RESULTS: Participants reported substantive gaps in the implementation of NVUGIB guidelines that included the following: lack of knowledge of the specifics of the NVUGIB guidelines (ER, ICU, nurses); limited belief in the value of guidelines, especially in areas where evidence is lacking (ER, ICU); limited belief in the value of available tools to support implementation of guidelines (GI); lack of knowledge of the roles and responsibilities of health care professions and disciplines, and lack of effective collaboration skills (ER, ICU and GI); variability of knowledge and skills of health care professionals within professions (eg, variability of nurses’ knowledge and skills in endoscopic procedures); and perceived overuse of intravenous proton pump inhibitor treatment, with limited concern regarding cost or side effect implications (all participants). CONCLUSIONS: In the present study population, ER, ICU and nurses did not adhere to NVUGIB guidelines because they were neither aware of nor familiar with them, whereas the GI lack of adherence to NVUGIB guidelines was influenced more by

ICU telemedicine uses audiovisual conferencing technology to provide critical care from a remote location. Research is needed to best define the optimal use of ICU telemedicine, but efforts are hindered by methodological challenges and the lack of an organized delivery approach. We convened an interdisciplinary working group to develop a research agenda in ICU telemedicine, addressing both methodological and knowledge gaps in the field. To best inform clinical decision-making and health policy, future research should be organized around a conceptual framework that enables consistent descriptions of both the study setting and the telemedicine intervention. The framework should include standardized methods for assessing the preimplementation ICU environment and describing the telemedicine program. This framework will facilitate comparisons across studies and improve generalizability by permitting context-specific interpretation. Research based on this framework should consider the multidisciplinary nature of ICU care and describe the specific program goals. Key topic areas to be addressed include the effect of ICU telemedicine on the structure, process, and outcome of critical care delivery. Ideally, future research should attempt to address causation instead of simply associations and elucidate the mechanism of action in order to determine exactly how ICU telemedicine achieves its effects. ICU telemedicine has significant potential to improve critical care delivery, but high-quality research is needed to best inform its use. We propose an agenda to advance the science of ICU telemedicine and generate research with the greatest potential to improve patient care. PMID:21729894

Critically ill adults have increased nutrition risk. Prior to procedures patients are often fasted, leading to nutritional deficits. The use of fasting guidelines may therefore help reduce deficits from accumulating. The aim of this work was to determine the impact on nutrition support delivery following the implementation of fasting guidelines in addition to characterizing staff knowledge of the guidelines. Retrospective data were collected on n = 74 patients at two different time points; prior to launch of fasting guidelines and post launch, with regards to estimated nutritional requirements, nutritional targets, volume of enteral nutrition (EN) delivered and periods of fasting. Clinical variables of interest were collected for up to 14 days. Questionnaires assessing staff knowledge/barriers to usage of the fasting guidelines were administered to ICU staff. 3 ICUs (General, Cardiac and Neurosciences) within University Hospital Southampton NHS Foundation Trust. Mechanically ventilated adults in an ICU and receiving exclusive EN. Comparison was made between pre- and post-guideline implementation with statistically significant improvements in the % EN delivered (76.4 ± 11.8 vs. 84.1 ± 10.8 (p = 0.0009)) and duration of feeds withheld (41.5 ± 26.6 vs. 27.6 ± 20.8 h (p = 0.02)). There were non-significant improvements pre- and post-implementation in the % of energy and protein delivered (80.7 ± 16.4 vs. 86.5 ± 17.3 (p = 0.15 (NS)); 74 ± 18.3 vs. 79 ± 18.5 (p = 0.15 (NS))). 77% of staff were familiar with the guidelines, whilst 42% requested further education. The main barriers to guideline compliance were delays and unpredictable timing of procedures, and differing guidance from senior staff and non-ICU teams. Implementation of fasting guidelines led to significant improvements in EN delivery and reduced duration of feed breaks. The use of fasting guidelines is a positive step towards increasing nutrition delivery in the ICU. Further

Interprofessional collaboration in the ICU: how to define?

Rose, Louise

2011-01-01

The intensive care unit (ICU) is a dynamic, complex and, at times, highly stressful work environment that involves ongoing exposure to the complexities of interprofessional team functioning. Failures of communication, considered examples of poor collaboration among health care professionals, are the leading cause of inadvertent harm across all health care settings. Evidence suggests effective interprofessional collaboration results in improved outcomes for critically ill patients. One recent study demonstrated a link between low standardized mortality ratios and self-identified levels of collaboration. The aim of this paper is to discuss determinants and complexities of interprofessional collaboration, the evidence supporting its impact on outcomes in the ICU, and interventions designed to foster better interprofessional team functioning. Elements of effective interprofessional collaboration include shared goals and partnerships including explicit, complementary and interdependent roles; mutual respect; and power sharing. In the ICU setting, teams continually alter due to large staff numbers, shift work and staff rotations through the institution. Therefore, the ideal 'unified' team working together to provide better care and improve patient outcomes may be difficult to sustain. Power sharing is one of the most complex aspects of interprofessional collaboration. Ownership of specialized knowledge, technical skills, clinical territory, or even the patient, may produce interprofessional conflict when ownership is not acknowledged. Collaboration by definition implies interdependency as opposed to autonomy. Yet, much nursing literature focuses on achievement of autonomy in clinical decision-making, cited to improve job satisfaction, retention and patient outcomes. Autonomy of health care professionals may be an inappropriate goal when striving to foster interprofessional collaboration. Tools such as checklists, guidelines and protocols are advocated, by some, as ways

Purpose: The purpose was to develop an end-of-life care (EOLC) policy for patients who are dying with an advanced life limiting illness and to develop practical procedural guidelines for limiting inappropriate therapeutic medical interventions and improve the quality of care of the dying within an ethical framework and through a professional and family/patient consensus process. Evidence: The Indian Society of Critical Care Medicine (ISCCM) published its first guidelines on EOLC in 2005 [1] which was later revised in 2012.[2] Since these publications, there has been an exponential increase in empirical information and discussion on the subject. The literature reviewed observational studies, surveys, randomized controlled studies, as well as guidelines and recommendations, for education and quality improvement published across the world. The search terms were: EOLC; do not resuscitate directives; withdrawal and withholding; intensive care; terminal care; medical futility; ethical issues; palliative care; EOLC in India; cultural variations. Indian Association of Palliative Care (IAPC) also recently published its consensus position statement on EOLC policy for the dying.[3] Method: An expert committee of members of the ISCCM and IAPC was formed to make a joint EOLC policy for the dying patients. Proposals from the chair were discussed, debated, and recommendations were formulated through a consensus process. The members extensively reviewed national and international established ethical principles and current procedural practices. This joint EOLC policy has incorporated the sociocultural, ethical, and legal perspectives, while taking into account the needs and situation unique to India. PMID:25249748

Economics of ICU organization and management.

The intensive care unit (ICU) is a complex system and the economic implications of altering care patterns in the ICU can be difficult to unravel. Few studies have specifically examined the economics of implementing organizational and management changes or acknowledged the many competing economic interests of patient, hospital,payer, and society. With continuously increasing healthcare costs,there is a great need for more studies focused on the optimal organization of the ICU. These studies should not focus solely on reductions in ICU length of stay but should strive to measure the true costs of care within a given healthcare system.

Community-acquired pneumonia (CAP) is an infectious respiratory disease with an incidence that ranges from 3 to 8 cases per 1,000 inhabitants per year. This incidence increases with age and comorbidities. Forty per cent of CAP patients require hospitalization and around 10% of these patients are admitted in an Intensive Care Unit (ICU). Several studies have suggested that the implementation of clinical guidelines has a positive impact in the outcome of patients including mortality and length of stay. The more recent and used guidelines are those from Infectious Diseases Society of America/American Thoracic Society, published in 2007, the 2009 from the British Thoracic Society, and that from the European Respiratory Society/European Society of Clinical Microbiology and Infectious Diseases, published in 2010. In Spain, the most recently released guideline is the Sociedad Española de Neumología y Cirugía Torácica-2011 guideline. The present guidelines GNAC are designed to be used by the majority of health-care professionals that can participate in the care of CAP patients including diagnosis, decision of hospital and ICU admission, treatment and prevention. The Centro Cochrane Iberoamericano (CCIB) has participated in summarizing the previous guidelines and in the bibliography search. For each one of the following sections the panel of experts has developed a table with recommendations classified according to its evidence, strength and practical applicability using the Grading of Recommendations of Assessment Development and Evaluations (GRADE) system: 1. Epidemiology, microbiological etiology and antibiotic resistances.2. Clinical and microbiological diagnosis.3. Prognostic scales and decision of hospital admission.4. ICU admission criteria. 5.

Despite the high risk for patient harm during unanticipated ICU evacuations, critical care providers receive little to no training on how to perform safe and effective ICU evacuations. We reviewed the pertinent published literature and offer suggestions for the critical care provider regarding ICU evacuation. The suggestions in this article are important for all who are involved in pandemics or disasters with multiple critically ill or injured patients, including front-line clinicians, hospital administrators, and public health or government officials. The Evacuation and Mobilization topic panel used the American College of Chest Physicians (CHEST) Guidelines Oversight Committee's methodology to develop seven key questions for which specific 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 using a modified Delphi process. Based on current best evidence, we provide 13 suggestions outlining a systematic approach to prepare for and execute an effective ICU evacuation during a disaster. Interhospital and intrahospital collaboration and functional ICU communication are critical for success. Pre-event planning and preparation are required for a no-notice evacuation. A Critical Care Team Leader must be designated within the Hospital Incident Command System. A three-stage ICU Evacuation Timeline, including (1) no immediate threat, (2) evacuation threat, and (3) evacuation implementation, should be used. Detailed suggestions on ICU evacuation, including regional planning, evacuation drills, patient transport preparation and equipment, patient prioritization and distribution for evacuation, patient information and tracking, and federal and international evacuation assistance systems, are also provided. Successful ICU evacuation during a disaster requires active preparation, participation

Innovative Designs for the Smart ICU.

Halpern, Neil A

2014-03-01

Successfully designing a new ICU requires clarity of vision and purpose and the recognition that the patient room is the core of the ICU experience for patients, staff, and visitors. The ICU can be conceptualized into three components: the patient room, central areas, and universal support services. Each patient room should be designed for single patient use and be similarly configured and equipped. The design of the room should focus upon functionality, ease of use, healing, safety, infection control, communications, and connectivity. All aspects of the room, including its infrastructure; zones for work, care, and visiting; environment, medical devices, and approaches to privacy; logistics; and waste management, are important elements in the design process. Since most medical devices used at the ICU bedside are really sophisticated computers, the ICU needs to be capable of supporting the full scope of medical informatics. The patient rooms, the central ICU areas (central stations, corridors, supply rooms, pharmacy, laboratory, staff lounge, visitor waiting room, on-call suite, conference rooms, and offices), and the universal support services (infection prevention, finishings and flooring, staff communications, signage and wayfinding, security, and fire and safety) work best when fully interwoven. This coordination helps establish efficient and safe patient throughput and care and fosters physical and social cohesiveness within the ICU. A balanced approach to centralized and decentralized monitoring and logistics also offers great flexibility. Synchronization of the universal support services in the ICU with the hospital's existing systems maintains unity of purpose and continuity across the enterprise and avoids unnecessary duplication of efforts.

Although "respect" and "dignity" are intuitive concepts, little formal work has addressed their systematic application in the ICU setting. After convening a multidisciplinary group of relevant experts, we undertook a review of relevant literature and collaborative discussions focused on the practice of respect in the ICU. We report the output of this process, including a summary of current knowledge, a conceptual framework, and a research program for understanding and improving the practice of respect and dignity in the ICU. We separate our report into findings and proposals. Findings include the following: 1) dignity and respect are interrelated; 2) ICU patients and families are vulnerable to disrespect; 3) violations of respect and dignity appear to be common in the ICU and overlap substantially with dehumanization; 4) disrespect may be associated with both primary and secondary harms; and 5) systemic barriers complicate understanding and the reliable practice of respect in the ICU. Proposals include: 1) initiating and/or expanding a field of research on the practice of respect in the ICU; 2) treating "failures of respect" as analogous to patient safety events and using existing quality and safety mechanisms for improvement; and 3) identifying both benefits and potential unintended consequences of efforts to improve the practice of respect. Respect and dignity are important considerations in the ICU, even as substantial additional research remains to be done.

Delirium is common in Intensive-Care-Unit (ICU) patients but under-recognized by bed-side clinicians when not using validated delirium-screening tools. The Confusion-Assessment-Method for the ICU (CAM-ICU) has demonstrated very good psychometric properties, and has been translated into many different languages though not into French. We undertook this opportunity to describe the translation process. The translation was performed following recommended guidelines. The updated method published in 2014 including introduction letters, worksheet and flowsheet for bed-side use, the method itself, case-scenarios for training and Frequently-Asked-Questions (32 pages) was translated into French language by a neuropsychological researcher who was not familiar with the original method. Then, the whole method was back-translated by a native English-French bilingual speaker. The new English version was compared to the original one by the Vanderbilt University ICU-delirium-team. Discrepancies were discussed between the two teams before final approval of the French version. The entire process took one year. Among the 3692 words of the back-translated version of the method itself, 18 discrepancies occurred. Eight (44%) lead to changes in the final version. Details of the translation process are provided. The French version of CAM-ICU is now available for French-speaking ICUs. The CAM-ICU is provided with its complete training-manual that was challenging to translate following recommended process. While many such translations have been done for other clinical tools, few have published the details of the process itself. We hope that the availability of such teaching material will now facilitate a large implementation of delirium-screening in French-speaking ICUs.

Chan, Paul S.; Cram, Peter

2011-01-01

Background: Remote coverage of ICUs is increasing, but staff acceptance of this new technology is incompletely characterized. We conducted a systematic review to summarize existing research on acceptance of tele-ICU coverage among ICU staff. Methods: We searched for published articles pertaining to critical care telemedicine systems (aka, tele-ICU) between January 1950 and March 2010 using PubMed, Cumulative Index to Nursing and Allied Health Literature, Global Health, Web of Science, and the Cochrane Library and abstracts and presentations delivered at national conferences. Studies were included if they provided original qualitative or quantitative data on staff perceptions of tele-ICU coverage. Studies were imported into content analysis software and coded by tele-ICU configuration, methodology, participants, and findings (eg, positive and negative staff evaluations). Results: Review of 3,086 citations yielded 23 eligible studies. Findings were grouped into four categories of staff evaluation: overall acceptance level of tele-ICU coverage (measured in 70% of studies), impact on patient care (measured in 96%), impact on staff (measured in 100%), and organizational impact (measured in 48%). Overall acceptance was high, despite initial ambivalence. Favorable impact on patient care was perceived by > 82% of participants. Staff impact referenced enhanced collaboration, autonomy, and training, although scrutiny, malfunctions, and contradictory advice were cited as potential barriers. Staff perceived the organizational impact to vary. An important limitation of available studies was a lack of rigorous methodology and validated survey instruments in many studies. Conclusions: Initial reports suggest high levels of staff acceptance of tele-ICU coverage, but more rigorous methodologic study is required. PMID:21051386

Estimating ICU bed capacity using discrete event simulation.

2012-01-01

The intensive care unit (ICU) in a hospital caters for critically ill patients. The number of the ICU beds has a direct impact on many aspects of hospital performance. Lack of the ICU beds may cause ambulance diversion and surgery cancellation, while an excess of ICU beds may cause a waste of resources. This paper aims to develop a discrete event simulation (DES) model to help the healthcare service providers determine the proper ICU bed capacity which strikes the balance between service level and cost effectiveness. The DES model is developed to reflect the complex patient flow of the ICU system. Actual operational data, including emergency arrivals, elective arrivals and length of stay, are directly fed into the DES model to capture the variations in the system. The DES model is validated by open box test and black box test. The validated model is used to test two what-if scenarios which the healthcare service providers are interested in: the proper number of the ICU beds in service to meet the target rejection rate and the extra ICU beds in service needed to meet the demand growth. A 12-month period of actual operational data was collected from an ICU department with 13 ICU beds in service. Comparison between the simulation results and the actual situation shows that the DES model accurately captures the variations in the system, and the DES model is flexible to simulate various what-if scenarios. DES helps the healthcare service providers describe the current situation, and simulate the what-if scenarios for future planning.

The ideal level of sedation in the ICU is an ongoing source of scrutiny. At higher levels of sedation, the current scoring systems are not ideal. BIS may be able to improve both. We evaluated literature on effectiveness of BIS monitoring in sedated mechanically ventilated (MV) ICU patients compared to clinical sedation scores (CSS). For this systematic review, full text articles were searched in OVID, MEDLINE, EMBASE, and Cochrane databases from 1986 - 2014. Additional studies were identified searching bibliographies/abstracts from national/international Critical Care Medicine conferences and references from searched articles retrieved. Search terms were: 'Clinical sedation scale, Bi-spectral Index, Mechanical ventilation, Intensive care Unit'. Included were prospective, randomized and non-randomized studies comparing BIS monitoring with any CSS in MV adult (>18 yr old) ICU patients. Studies were graded for quality of evidence based on bias as established by the GRADE guidelines. Additional sources of bias were examined. There were five studies which met inclusion criteria. All five studies were either unclear or high risk for blinding of participants and blinding of outcome assessment. All papers had at least one source of additional high risk, or unclear/unstated. BIS monitoring in the mechanically ventilated ICU patient may decrease sedative drug dose, recall, and time to wake-up. The studies suggesting this are severely limited methodologically. BIS, when compared to subjective CSSs, is not, at this time, clearly indicated. An appropriately powered randomized, controlled study is needed to determine if this monitoring modality is of use on the ICU.

Reconciling divergent results of the latest parenteral nutrition studies in the ICU.

Recent studies on the optimal modalities to feed patients during the ICU stay show divergent results. The level and the timing of energy provision is a critical issue, associated with the clinical outcome. These results questioned the clinical relevance of the recent guidelines issued by American, Canadian and European academic societies. Four recent prospective randomized studies enrolled critically ill patients who received various nutritional regimens and tested the effect of nutritional support on outcome. The Tight Calorie balance Control Study (TICACOS) targeted on calorie administration according to measured energy expenditure and found increased ICU morbidity but improved hospital mortality. The large EpaNIC study compared 'early' with 'late' (parenteral nutrition) nutrition, mostly in patients after cardiac surgery, and found an increased morbidity associated with early parenteral nutrition. The supplemental parenteral nutrition (SPN) study randomized the patients after 3 days and targeted the calories administered by parenteral nutrition as a complement to unsuccessful enteral nutrition using indirect calorimetry. The SPN resulted in less nosocomial infections and shorter duration of mechanical ventilation. Finally, a recent Australian study enrolled patients unable to be early fed enterally to receive, or not, parenteral nutrition targeted at 1500 kcal. No complications were noted in the parenteral nutrition group. Lessons from all these studies are summarized and should help in designing better studies and guidelines. The critical analysis of recent prospective studies comparing various levels of calorie administration, enteral versus parenteral nutrition and enteral versus SPN confirms the recommendations to avoid underfeeding and overfeeding. Parenteral nutrition, required if enteral feeding is failing, and if adjusted up to a measured optimal level, may improve outcome.

The purpose of this paper is to examine nurses' attitudes towards safety culture in six Saudi Arabian intensive care units (ICUs). The study is descriptive with a cross-sectional design. The Safety Attitude Questionnaire (SAQ)-ICU version was distributed and 216 completed questionnaires were returned. The findings provide a basis for further research on Saudi Arabian ICU safety culture. This study showed that the SAQ-ICU can be used to measure safety climate to identify areas for improvement according to nurse attitudes and perceptions. Findings indicate that ICU safety culture is an important issue that hospital managers should prioritise. The SAQ-ICU questionnaire, used to measure safety climate in Saudi Arabian ICUs, identifies service strengths and improvement areas according to attitudes and perceptions. To the knowledge, this is the first study to use SAQ to examine nurses' safety culture attitudes in Saudi Arabian ICUs. The present findings provide a baseline and further details about Saudi Arabian ICU safety. Study participants represented nine nationalities, indicating the nursing workforce's diversity, which is expected to continue in the future. Such a nursing cultural heterogeneity calls for further studies to examine and evaluate attitudes and values to improve ICU safety culture.

RATIONALE and OBJECTIVE Delirium assessments in critically ill infants and young children pose unique challenges due to evolution of cognitive and language skills. The objectives of this study were to determine the validity and reliability of a fundamentally objective and developmentally appropriate delirium assessment tool for critically ill infants and preschool-aged children, and to determine delirium prevalence. DESIGN and SETTING Prospective, observational cohort validation study of the PreSchool Confusion Assessment Method for the ICU (psCAM-ICU) in a tertiary medical center pediatric ICU. PATIENTS Participants aged 6 months to 5 years and admitted to the pediatric ICU regardless of admission diagnosis were enrolled. INTERVENTIONS, MEASUREMENTS and MAIN RESULTS An interdisciplinary team created the psCAM-ICU for pediatric delirium monitoring. To assess validity, patients were independently assessed for delirium daily by the research team using the psCAM-ICU and by a child psychiatrist using the Diagnostic and Statistical Manual of Mental Disorders criteria. Reliability was assessed using blinded, concurrent psCAM-ICU evaluations by research staff. A total of 530-paired delirium assessments were completed among 300 patients, with a median age of 20 months (IQR 11, 37) and 43% requiring mechanical ventilation. The psCAM-ICU demonstrated a specificity of 91% (95%CI 90, 93), sensitivity of 75% (72, 78), negative predictive value of 86% (84, 88), positive predictive value of 84% (81, 87), and a reliability kappa statistic of 0.79 (0.76, 0.83). Delirium prevalence was 44% using the psCAM-ICU and 47% by the reference-rater. The rates of delirium were 53% vs. 56% in patients < 2 years of age and 33% vs. 35% in patients ≥ 2 - 5 years of age using the psCAM-ICU and reference-rater respectively. The short-form psCAM-ICU maintained a high specificity (87%) and sensitivity (78%) in post-hoc analysis. CONCLUSIONS The psCAM-ICU is a highly valid and reliable delirium

Therapeutic hypothermia (TH) is one of three interventions that have demonstrated to improve patients' neurological outcome after cardiac arrest. The aim of this study was to investigate the effect of the 2010 resuscitation guidelines on TH implementation in various Italian Intensive Care Units (ICU). A structured questionnaire was submitted to Italian ICU. The questionnaire was addressed to determine the procedures of TH in each ICU or, on the contrary, the reason for not employing the therapy. We obtained complete information from 770 of 847 Italian ICU (91%). Out of 405 Units included in the analysis only 223 (55.1%) reported to use TH in comatose patients after return of spontaneous circulation. The trend of TH implementation shows a stable increase, particularly after 2006 but there is no evident acceleration after the strong indication of the 2010 guidelines. There was a rise of about 3.4 times in the number of Italian ICU using TH as compared to the 2007 survey (an increase of 68% per year). One hundred and eighty-two (44.9%) units did not use TH mainly because of lack of equipment, economic issues or the conviction of the difficulty of execution. TH is still under-used in Italy (55.1%) even though the therapy is strongly recommended in the 2010 guidelines. However, the increase in the adoption of hypothermia has been significant in the past 5 years (68%/years) and the awareness of the efficacy is almost consolidated among intensivists, being logistic problems the leading cause for non-adoption.

We investigated the impact of delirium on illness severity, psychological state, and memory in acute respiratory distress syndrome patients with very long ICU stay. Prospective cohort study in the medical-surgical ICUs of 2 teaching hospitals. Very long ICU stay (>75days) and prolonged delirium (≥40days) thresholds were determined by ROC analysis. Subjects were ≥18years, full-code, and provided informed consent. Illness severity was assessed using Acute Physiology and Chronic Health Evaluation IV, Simplified Acute Physiology Score-3, and Sequential Organ Failure Assessment scores. Psychological impact was assessed using the Hospital Anxiety and Depression Scale, Impact of Event Scale-Revised, and the 14-question Post-Traumatic Stress Syndrome (PTSS-14). Memory was assessed using the ICU Memory Tool survey. 181 subjects were included. Illness severity did not correlate with delirium duration. On logistic regression, only PTSS-14<49 correlated with delirium (p=0.001; 95% CI 1.011, 1.041). 49% remembered their ICU stay clearly. 47% had delusional memories, 50% reported intrusive memories, and 44% reported unexplained feelings of panic or apprehension. Delirium was associated with memory impairment and PTSS-14 scores suggestive of PTSD, but not illness severity. Copyright © 2017. Published by Elsevier Inc.

In this study of the implementation of the awakening and breathing coordination, delirium monitoring/management, and early exercise/mobility bundle in a tertiary care setting, clear factors were identified that both advanced and impeded adoption of this complex intervention that requires interprofessional education, coordination, and cooperation. Focusing on these factors preemptively should enable a more effective and lasting implementation of the bundle and better care for critically ill patients. Lessons learned from this study will also help healthcare providers optimize implementation of the recent ICU pain, agitation, and delirium guidelines, which has many similarities but also some important differences as compared with the awakening and breathing coordination, delirium monitoring/management, and early exercise/mobility bundle.

Background While trauma patients are frequently cared for in the ICU, admission triage criteria are unclear and may vary among providers and institutions. The benefits of close monitoring must be weighed against the economic and opportunity costs of an ICU admission. Materials and Methods We conducted a retrospective cohort study of patients treated for blunt splenic injuries at 30 level I and II Pennsylvania trauma centers, 2011–2014. We used multivariable logistic regression to assess the relationship between ICU admission and mortality, adjusting for patient characteristics, injury characteristics, and physiology. We calculated center-level observed-to-expected ratios for ICU utilization and mortality and evaluated correlations with Spearman’s rho. We compared the proportion of patients receiving critical care procedures, such as mechanical ventilation or central line placement, between high- and low-ICU-utilization centers. Results Of 2,587 patients with blunt splenic injuries, 63.9% (1,654) were admitted to the ICU. Median injury severity score (ISS) was 17 overall, 13 for non-ICU patients and 17 for ICU patients (p < 0.001). In multivariable logistic regression, ICU admission was not significantly associated with mortality. Center-level risk-adjusted ICU admission rates ranged from 17.9% to 87.3%. Risk-adjusted mortality rates ranged from 1.2% to 9.6%. There was no correlation between O:E ratios for ICU utilization and mortality (rs = −0.2595, p=0.2103). Proportionately fewer ICU patients at high-utilization centers received critical care procedures than at low-utilization centers. Conclusions Risk-adjusted ICU utilization rates for splenic trauma varied widely among trauma centers, with no clear relationship to mortality. Standardizing ICU admission criteria could improve resource utilization without increasing mortality. PMID:27363642

A software communication tool for the tele-ICU.

The Tele Intensive Care Unit (tele-ICU) supports a high volume, high acuity population of patients. There is a high-volume of incoming and outgoing calls, especially during the evening and night hours, through the tele-ICU hubs. The tele-ICU clinicians must be able to communicate effectively to team members in order to support the care of complex and critically ill patients while supporting and maintaining a standard to improve time to intervention. This study describes a software communication tool that will improve the time to intervention, over the paper-driven communication format presently used in the tele-ICU. The software provides a multi-relational database of message instances to mine information for evaluation and quality improvement for all entities that touch the tele-ICU. The software design incorporates years of critical care and software design experience combined with new skills acquired in an applied Health Informatics program. This software tool will function in the tele-ICU environment and perform as a front-end application that gathers, routes, and displays internal communication messages for intervention by priority and provider.

Utilizing findings from the APACHE III research to develop operational information system for the ICU--the APACHE III ICU Management System.

The APACHE III data base reflects the disease, physiologic status, and outcome data from 17,400 ICU patients at 40 hospitals, 26 of which were randomly selected from representative geographic regions, bed size, and teaching status. This provides a nationally representative standard for measuring several important aspects of ICU performance. Results from the study have now been used to develop an automated information system to provide real time information about expected ICU patient outcome, length of stay, production cost, and ICU performance. The information system provides several new capabilities to ICU clinicians, clinic, and hospital administrators. Among the system's capabilities are: the ability to compare local ICU performance against predetermined criteria; the ability to forecast nursing requirements; and, the ability to make both individual and group patient outcome predictions. The system also provides improved administrative support by tracking ICU charges at the point of origin and reduces staff workload eliminating the requirement for several manually maintained logs and patient lists. APACHE III has the capability to electronically interface with and utilize data already captured in existing hospital information systems, automated laboratory information systems, and patient monitoring systems. APACHE III will also be completely integrated with several CIS vendors' products. PMID:1807779

ICU scoring systems allow prediction of patient outcomes and comparison of ICU performance.

Becker, R B; Zimmerman, J E

Too much time and effort are wasted in attempts to pass final judgment on whether systems for ICU prognostication are "good or bad" and whether they "do or do not" provide a simple answer to the complex and often unpredictable question of individual mortality in the ICU. A substantial amount of data supports the usefulness of general ICU prognostic systems in comparing ICU performance with respect to a wide variety of endpoints, including ICU and hospital mortality, duration of stay, and efficiency of resource use. Work in progress is analyzing both general resource use and specific therapeutic interventions. It also is time to fully acknowledge that statistics never can predict whether a patient will die with 100% accuracy. There always will be exceptions to the rule, and physicians frequently will have information that is not included in prognostic models. In addition, the values of both physicians and patients frequently lead to differences in how a probability in interpreted; for some, a 95% probability estimate means that death is near and, for others, this estimate represents a tangible 5% chance for survival. This means that physicians must learn how to integrate such estimates into their medical decisions. In doing so, it is our hope that prognostic systems are not viewed as oversimplifying or automating clinical decisions. Rather, such systems provide objective data on which physicians may ground a spectrum of decisions regarding either escalation or withdrawal of therapy in critically ill patients. These systems do not dehumanize our decision-making process but, rather, help eliminate physician reliance on emotional, heuristic, poorly calibrated, or overly pessimistic subjective estimates. No decision regarding patient care can be considered best if the facts upon which it is based on imprecise or biased. Future research will improve the accuracy of individual patient predictions but, even with the highest degree of precision, such predictions are useful

We hypothesized that intensivists unfamiliar with an ICU team and the context of that ICU would affect patient outcomes. We examined differences in mortality when ICU patients were admitted under intensivists routinely working in that ICU and compared with those admitted by intensivists familiar with an ICU elsewhere in the same hospital. A 5-year natural experimental crossover study involving patients admitted to four ICUs in a large U.K. teaching hospital. During a period of service reconfiguration, intensivists routinely rostered to work in one ICU worked in another of the hospital's four ICUs. "Home" intensivists were those who continued to work in their usual ICU; "visitor" intensivists were those who delivered care in an unfamiliar ICU. Patient data were obtained from electronic patient records to provide analysis on sex, age, admission Sequential Organ Failure Assessment score, date and time of admission, and admission type (elective, transfer, or unplanned). We analyzed 9,981 admissions to four separate ICUs over a 5-year period. In total, 34.5% of patients were admitted by intensivists working in nonfamiliar surroundings. Visitor intensivists admitted patients with similar age and gender distributions but with greater physiologic derangement (mean Sequential Organ Failure Assessment score, 4.1 ± 2.8 vs 3.9 ± 2.8; p < 0.001) than home intensivists. Overall ICU mortality rates were higher in visitor intensivists, albeit not significantly so (11.5% vs 10.2%; p = 0.052). However, when the ICUs were analyzed separately, visitor mortality rates were found to be significantly higher than for home intensivists in two of the four ICUs (p = 0.017, 0.006). A multivariable analysis adjusting for confounding factors and the clustering of consultants revealed that the overall mortality rate was significantly higher for visitors (odds ratio, 1.18; 95% CI, 1.02-1.37; p = 0.024). A significant interaction between the ICU and visitor status was also detected (p

Post-intensive care syndrome includes the multiple consequences of an intensive care unit (ICU) stay for patients and families. It has become a new challenge for intensivists. Prevention programs have been disappointing, except for ICU diaries, which report the patient's story in the ICU. However, the effectiveness of ICU diaries for patients and families is still controversial, as the interpretation of the results of previous studies was open to criticism hampering an expanded use of the diary. The primary objective of the study is to evaluate the post-traumatic stress syndrome in patients. The secondary objectives are to evaluate the post-traumatic stress syndrome in families, anxiety and depression symptoms in patients and families, and the recollected memories of patients. Endpoints will be evaluated 3 months after ICU discharge or death. A prospective, multicenter, randomized, assessor-blind comparative study of the effect of an ICU diary on patients and families. We will compare two groups: one group with an ICU diary written by staff and family and given to the patient at ICU discharge or to the family in case of death, and a control group without any ICU diary. Each of the 35 participating centers will include 20 patients having at least one family member who will likely visit the patient during their ICU stay. Patients must be ventilated within 48 h after ICU admission and not have any previous chronic neurologic or acute condition responsible for cognitive impairments that would hamper their participation in a phone interview. Three months after ICU discharge or death of the patient, a psychologist will contact the patient and family by phone. Post-traumatic stress syndrome will be evaluated using the Impact of Events Scale-Revised questionnaire, anxiety and depression symptoms using the Hospital Anxiety and Depression Scale questionnaire, both in patients and families, and memory recollection using the ICU Memory Tool Questionnaire in patients.

Advances in critical care have resulted in improved intensive care unit (ICU) mortality. However, improved ICU survival has resulted in a growing number of ICU survivors living with long-term sequelae of critical illness, such as impaired physical function and quality of life (QOL). In addition to critical illness, prolonged bed rest and immobility may lead to severe physical deconditioning and loss of muscle mass and muscle weakness. ICU-acquired weakness is associated with increased duration of mechanical ventilation and weaning, longer ICU and hospital stay, and increased mortality. These physical impairments may last for years after ICU discharge. Early Physical Medicine and Rehabilitation (PM&R) interventions in the ICU may attenuate or prevent the weakness and physical impairments occurring during critical illness. This article reviews the evidence regarding safety, feasibility, barriers, and benefits of early PM&R interventions in ICU patients and discusses the limited existing data on early PM&R in the neurological ICU and future directions for early PM&R in the ICU.

Incidence of Multidrug-Resistant Pseudomonas Spp. in ICU Patients with Special Reference to ESBL, AMPC, MBL and Biofilm Production

PubMed Central

Gupta, Richa; Malik, Abida; Rizvi, Meher; Ahmed, S. Moied

2016-01-01

Background: Multidrug-resistant (MDR) Pseudomonas spp. have been reported to be the important cause of ICU infections. The appearance of ESBL, AmpC and MBL genes and their spread among bacterial pathogens is a matter of great concern. Biofilm production also attributes to antimicrobial resistance due to close cell to cell contact that permits bacteria to more effectively transfer plasmids to one another. This study aimed at determining the incidence of ESBL, AmpC, MBL and biofilm producing Pseudomonas spp. in ICU patients. Material and Methods: The clinical specimens were collected aseptically from 150 ICU patients from February 2012 to October 2013. Identification and antimicrobial susceptibility was performed according to Clinical and Laboratory Standards Institute (CLSI) guidelines. ESBLs and AmpC were detected phenotypically and genotypically. MBL was detected by modified Hodge and imipenem-EDTA double-disk synergy test. Results: Pseudomonas spp. 35(28%) were the most prevalent pathogen in ICU infections. Multidrug resistance and biofilm production was observed in 80.1% and 60.4% isolates, respectively. Prevalence of ESBL, AmpC and MBL was 22.9%, 42.8% and 14.4%, respectively. The average hospital stay was 25 days and was associated with 20% mortality. Conclusions: A regular surveillance is required to detect ESBL, AmpC and MBL producers especially in ICU patients. Carbapenems should be judiciously used to prevent their spread. The effective antibiotics, such as fluoroquinolones and piperacillin-tazobactum should be used after sensitivity testing. PMID:27013841

How to develop a tele-ICU model?

PubMed

Rogove, Herb

2012-01-01

The concept of the tele-ICU (intensive care unit) is about 30 years old and more hospitals are utilizing it to cover multiple hospitals in their system or for hospitals that lack on-site critical care coverage such as in the rural setting. Doing a needs analysis, picking the appropriate committee to oversee development of the correct model, choosing quality metrics to measure, and designing an implementation plan that has a timeline is how the process should begin. Research including visitation to established programs and connecting with professional societies are helpful. Developing both a business and financial plan will optimize the value of a tele-ICU program. The innovative ICU nursing director will help to integrate a telemedicine program seamlessly with the on-site program to insure a successful program that benefits patients, their families, the ICU staff, and the hospital.

To evaluate the impact of a redesigned intensive care unit (ICU) nursing discharge process on ICU discharge delay, hospital mortality, and ICU readmission within 72 hours. A quality improvement study using a time series design and statistical process control analysis was conducted in one Australian general ICU. The primary outcome measure was hours of discharge delay per patient discharged alive per month, measured for 15 months prior to, and for 12 months after the redesigned process was implemented. The redesign process included appointing a change agent to facilitate process improvement, developing a patient handover sheet, requesting ward staff to nominate an estimated transfer time, and designing a daily ICU discharge alert sheet that included an expected date of discharge. A total of 1,787 ICU discharges were included in this study, 1,001 in the 15 months before and 786 in the 12 months after the implementation of the new discharge processes. There was no difference in in-hospital mortality after discharge from ICU or ICU readmission within 72 hours during the study period. However, process improvement was demonstrated by a reduction in the average patient discharge delay time of 3.2 hours (from 4.6 hour baseline to 1.0 hours post-intervention). Involving both ward and ICU staff in the redesign process may have contributed to a shared situational awareness of the problems, which led to more timely and effective ICU discharge processes. The use of a change agent, whose ongoing role involved follow-up of patients discharged from ICU, may have helped to embed the new process into practice. ©2011 Sigma Theta Tau International.

Using simulation to determine the need for ICU beds for surgery patients.

PubMed

Troy, Philip Marc; Rosenberg, Lawrence

2009-10-01

As the need for surgical ICU beds at the hospital increases, the mismatch between demand and supply for those beds has led to the need to understand the drivers of ICU performance. A Monte Carlo simulation study of ICU performance was performed using a discrete event model that captured the events, timing, and logic of ICU patient arrivals and bed stays. The study found that functional ICU capacity, ie, the number of occupied ICU beds at which operative procedures were canceled if they were known to require an ICU stay, was the main determinant of the wait, the number performed, and the number of cancellations of operative procedures known to require an ICU stay. The study also found that actual and functional ICU capacity jointly explained ICU utilization and the mean number of patients that should have been in the ICU that were parked elsewhere. The study demonstrated the necessity of considering actual and functional ICU capacity when analyzing surgical ICU bed requirements, and suggested the need for additional research on synchronizing demand with supply. The study also reinforced the authors' sense that simulation facilitates the evaluation of trade-offs between surgical management alternatives proposed by experts and the identification of unexpected drawbacks or opportunities of those proposals.

Escalation of Commitment in the Surgical ICU.

PubMed

Braxton, Carla C; Robinson, Celia N; Awad, Samir S

2017-04-01

Escalation of commitment is a business term that describes the continued investment of resources into a project even after there is objective evidence of the project's impending failure. Escalation of commitment may be a contributor to high healthcare costs associated with critically ill patients as it has been shown that, despite almost certain futility, most ICU costs are incurred in the last week of life. Our objective was to determine if escalation of commitment occurs in healthcare settings, specifically in the surgical ICU. We hypothesize that factors previously identified in business and organizational psychology literature including self-justification, accountability, sunk costs, and cognitive dissonance result in escalation of commitment behavior in the surgical ICU setting resulting in increased utilization of resources and cost. A descriptive case study that illustrates common ICU narratives in which escalation of commitment can occur. In addition, we describe factors that are thought to contribute to escalation of commitment behaviors. Escalation of commitment behavior was observed with self-justification, accountability, and cognitive dissonance accounting for the majority of the behavior. Unlike in business decisions, sunk costs was not as evident. In addition, modulating factors such as personality, individual experience, culture, and gender were identified as contributors to escalation of commitment. Escalation of commitment occurs in the surgical ICU, resulting in significant expenditure of resources despite a predicted and often known poor outcome. Recognition of this phenomenon may lead to actions aimed at more rational decision making and may contribute to lowering healthcare costs. Investigation of objective measures that can help aid decision making in the surgical ICU is warranted.

Intensive care unit (ICU) costs account for a great part of a hospital's expenses. The objective of the present study was to measure the patient-specific cost of ICU treatment, to identify the most important cost drivers in ICU and to examine the role of various contributing factors in cost configuration. A retrospective cost analysis of all ICU patients who were admitted during 2011 in a Greek General, seven-bed ICU and stayed for at least 24hours was performed, by applying bottom-up analysis. Data collected included demographics and the exact cost of every single material used for patients' care. Prices were yielded from the hospital's purchasing costs and from the national price list of the imaging and laboratory tests, which was provided by the Ministry of Health. A total of 138 patients were included. Variable cost per ICU day was €573.18. A substantial cost variation was found in the total costs obtained for individual patients (median: €3443, range: €243.70-€116,355). Medicines were responsible for more than half of the cost and antibiotics accounted for the largest part of it, followed by blood products and cardiovascular drugs. Medical cause of admission, severe illness and increased length of stay, mechanical ventilation and dialysis were the factors associated with cost escalation. ICU variable cost is patient-specific, varies according to each patient's needs and is influenced by several factors. The exact estimation of variable cost is a pre-requisite in order to control ICU expenses. Copyright © 2016 Elsevier Ltd. All rights reserved.

Palliative Care Consultations in the Neuro-ICU: A Qualitative Study.

Tran, Len N; Back, Anthony L; Creutzfeldt, Claire J

2016-10-01

Integration of palliative care (PC) into the neurological intensive care unit (neuro-ICU) is increasingly recommended, but evidence regarding the best practice is lacking. We conducted a qualitative analysis exploring current practices and key themes of specialist PC consultations in patients admitted to a single neuro-ICU. We retrospectively identified all patients who were admitted to the neuro-ICU for ≥24 h and received a PC consultation between January and August 2014. We reviewed PC consultation notes and neuro-ICU progress notes from the electronic health records of these patients. We performed content analysis on the PC notes. Twenty-five neuro-ICU patients (4 %) received a PC consultation over 8 months with the most prevalent reason of clarifying goals of care. The main distinctions between patients with and those without (n = 580) a PC consultation were ICU length of stay (median 8.2 vs. 2.8 days) and death in the neuro-ICU (56 % vs. 11 %). The most prevalent themes addressed in the PC consultation notes were (1) discussing prognosis, (2) eliciting patient and family values, (3) understanding medical options, and (4) identifying conflict. PC consultations in the neuro-ICU emphasize family coping and decision-making by helping discuss prognosis and exploring patient and family values as well as their ability to understand the medical information. Several features suggest that earlier integration of PC into neuro-ICU care may enhance both coping and the decision-making process.

A recent change in our ICU allowed further investigation. Methods Pre-move ICU-A and pre-move ICU-B were open-plan units. In March 2007, ICU-A moved to single-patient rooms (post-move ICU-A). ICU-B remained unchanged (post-move ICU-B). The same physicians cover both ICUs. Cultures of specified resistant organisms in surveillance or clinical cultures from consecutive patients staying >48 hours were compared for the different ICUs and periods to assess the effect of ICU design on acquisition of resistant organisms. Results Data were collected for 62, 62, 44 and 39 patients from pre-move ICU-A, post-move ICU-A, pre-move ICU-B and post-move ICU-B, respectively. Fewer post-move ICU-A patients acquired resistant organisms (3/62, 5%) compared with post-move ICU-B patients (7/39, 18%; P = 0.043, P = 0.011 using survival analysis) or pre-move ICU-A patients (14/62, 23%; P = 0.004, P = 0.012 on survival analysis). Only the admission period was significant for acquisition of resistant organisms comparing pre-move ICU-A with post-move ICU-A (hazard ratio = 5.18, 95% confidence interval = 1.03 to 16.06; P = 0.025). More antibiotic-free days were recorded in post-move ICU-A (median = 3, interquartile range = 0 to 5) versus post-move ICU-B (median = 0, interquartile range = 0 to 4; P = 0.070) or pre-move ICU-A (median = 0, interquartile range = 0 to 4; P = 0.017). Adequate hand hygiene was observed on 140/242 (58%) occasions in post-move ICU-A versus 23/66 (35%) occasions in post-move ICU-B (P < 0.001). Conclusions Improved ICU design, and particularly use of single-patient rooms, decreases acquisition of resistant bacteria and antibiotic use. This observation should be considered in future ICU design. PMID:21914222

Family members of patients who die in an ICU are at increased risk of psychological sequelae compared to those who experience a death in hospice. This study explored differences in rates and levels of complicated grief (CG), posttraumatic stress disorder (PTSD), and depression between family members of patients who died in an ICU versus a non-ICU hospital setting. Differences in family members' most distressing experiences at the patient's end of life were also explored. The study was an observational cohort. Subjects were next of kin of 121 patients who died at a large, Midwestern academic hospital; 77 died in the ICU. Family members completed measures of CG, PTSD, depression, and end-of-life experiences. Participants were primarily Caucasian (93%, N = 111), female (81%, N = 98), spouses (60%, N = 73) of the decedent, and were an average of nine months post-bereavement. Forty percent of family members met the Inventory of Complicated Grief CG cut-off, 31% met the Impact of Events Scale-Revised PTSD cut-off, and 51% met the Center for Epidemiologic Studies Depression Scale depression cut-off. There were no significant differences in rates or levels of CG, PTSD, or depressive symptoms reported by family members between hospital settings. Several distressing experiences were ranked highly by both groups, but each setting presented unique distressing experiences for family members. Psychological distress of family members did not differ by hospital setting, but the most distressing experiences encountered at end of life in each setting highlight potentially unique interventions to reduce distress post-bereavement for family members.

Examine the association of a daily palliative care needs checklist on outcomes for family members of patients discharged from the neurosciences intensive care unit (neuro-ICU). We conducted a prospective, longitudinal cohort study in a single, thirty-bed neuro-ICU in a regional comprehensive stroke and level 1 trauma center. One of two neuro-ICU services that admit patients to the same ICU on alternating days used a palliative care needs checklist during morning work rounds. Between March and October, 2015, surveys were mailed to family members of patients discharged from the neuro-ICU. Nearly half of surveys (n = 91, 48.1%) were returned at a median of 4.7 months. At the time of survey completion, mean Modified rankin scale score (mRS) of neuro-ICU patients was 3.1 (SD 2). Overall ratings of quality of care were relatively high (82.2 on a 0-100 scale) with 32% of family members meeting screening criteria for depressive syndrome. The primary outcome measuring family satisfaction, consisting of eight items from the Family Satisfaction in the ICU questionnaire, did not differ significantly between families of patients from either ICU service nor did family ratings of depression (PHQ-8) and post-traumatic stress (PCL-17). Among families of patients discharged from the neuro-ICU, the daily use of a palliative care needs checklist had no measurable effect on family satisfaction scores or long-term psychological outcomes. Further research is needed to identify optimal interventions to meet the palliative care needs specific to family members of patients treated in the neuro-ICU.

Studies have identified processes that are associated with more favorable length of stay (LOS) outcomes when an ICU telemedicine program is implemented. Despite these studies, the relation of the acceptance of ICU telemedicine management services by individual ICUs to LOS outcomes is unknown. This is a single ICU telemedicine center study that compares LOS outcomes among three groups of intensivist-staffed mixed medical-surgical ICUs that used alternative comanagement strategies. The proportion of provider orders recorded by an ICU telemedicine provider to all recorded orders was compared among ICUs that used a monitor and notify comanagement approach, a direct intervention with timely notification process, and ICUs that used a mix of these two approaches. The primary outcome was acuity-adjusted hospital LOS. ICUs that used the direct intervention with timely notification strategy had a significantly larger proportion of provider orders recorded by ICU telemedicine physicians than the mixed methods of comanagement group, which had a larger proportion than ICUs that used the monitor and notify method (P < .001). Acuity-adjusted hospital LOS was significantly lower for the direct intervention with timely notification comanagement strategy (0.68; 0.65-0.70) compared with the mixed methods group (0.70 [0.69-0.72]; P = .01), which was significantly lower than the monitor and notify group (0.83 [0.80-0.86]; P < .001). Direct intervention with timely notification strategies of ICU telemedicine comanagement were associated with shorter LOS outcomes than monitor and notify comanagement strategies.

Wang, Anson; Ortega-Gutierrez, Santiago; Petersen, Nils H

2018-05-17

The purpose of this review is to briefly describe the concept of cerebral autoregulation, to detail several bedside techniques for measuring and assessing autoregulation, and to outline the impact of impaired autoregulation on clinical and functional outcomes in acute brain injury. Furthermore, we will review several autoregulation studies in select forms of acute brain injuries, discuss the potential for its use in patient management in the ICU, and suggest further avenues for research. Cerebral autoregulation plays a critical role in regulating cerebral blood flow, and impaired autoregulation has been associated with worse functional and clinical outcomes in various acute brain injuries. There exists a multitude of methods to assess the autoregulatory state in patients using both invasive and non-invasive modalities. Continuous monitoring of patients in the ICU has yielded autoregulatory-derived optimal perfusion pressures that may prevent secondary injury and improve outcomes. Measuring autoregulation continuously at the bedside is now a feasible option for clinicians working in the ICU, although there exists a great need to standardize autoregulatory measurement. While the clinical benefits await prospective and randomized trials, autoregulation-derived parameters show enormous potential for creating an optimal physiological environment for the injured brain.

Clostridium difficile in the ICU

Dubberke, Erik R.; Kollef, Marin

2011-01-01

Clostridium difficile infection (CDI) management has become more daunting over the past decade because of alarming increases in CDI incidence and severity both in the hospital and in the community. This increase has concomitantly caused significant escalation of the health-care economic burden caused by CDI, and it will likely be translated to increased ICU admission and attributable mortality. Some possible causes for difficulty in management of CDI are as follows: (1) inability to predict and prevent development of severe/complicated or relapsing CDI in patients who initially present with mild symptoms; (2) lack of a method to determine who would have benefited a priori from initiating vancomycin treatment first instead of treatment with metronidazole; (3) lack of sensitive and specific CDI diagnostics; (4) changing epidemiology of CDI, including the emergence of a hypervirulent, epidemic C difficile strain associated with increased morbidity and mortality; (5) association of certain high-usage nonantimicrobial medications with CDI; and (6) lack of treatment regimens that leave the normal intestinal flora undisturbed while treating the primary infection. The objective of this article is to present current management and prevention guidelines for CDI based on recommendations by the Society for Healthcare Epidemiology of America and Infectious Diseases Society of America and potential new clinical management strategies on the horizon.

Background Stress ulcer prophylaxis (SUP) is recommended in some situations to prevent upper gastrointestinal bleeding and is a component of standard care for patients admitted to the intensive care unit (ICU). Proton pump inhibitors (PPIs), already among the most widely prescribed drug classes, are being increasingly used. Objective To describe PPI prescribing patterns and their changes after the dissemination of guidelines. Setting Paediatric ICU (PICU), Robert-Debré Teaching Hospital, Paris, France, which admits about 800 patients annually, from full-term neonates to 18-year-olds. Method Prospective observational study with two 6-week observation periods (July-August and September-October, 2013), before and after dissemination in the PICU of PPI prescribing guidelines. Main outcome measure Changes in PPI prescribing patterns (prevalence, dosage, and indication) after the guidelines. Results The number of patients admitted to the PICU was 77 (mean age 4.6 years [range 1 day-18 years]) before and 70 (mean age 3.8 years [range 1 day-17 years]) after the guidelines. During both periods, SUP was the most common reason for PPI prescribing. The proportion of patients prescribed PPIs dropped significantly, from 51% before the guidelines to 30% after the guidelines (p < 0.001). Mean daily dosage also decreased significantly, from 1.5 mg/kg/(range 0.5-4.4) to 1.1 mg/kg (range 0.7-1.8) (p < 0.002). None of the patients experienced upper gastrointestinal bleeding during either period. Conclusion Off-label PPI prescribing for SUP was common in our PICU. The introduction of guidelines was associated with a significant decrease in PPI use and dosage. This study confirms that guidelines can change PPI prescribings patterns in paediatric practice.

Virtual rapid response: the next evolution of tele-ICU.

Hawkins, Carrie L

The first of its kind in the Veterans Affairs (VA) system, the Denver VA Medical Center's tele-intensive care unit (ICU) program is unique because it is entirely nurse driven. A nontraditional tele-ICU model, the program was tailored to meet the needs of rural veterans by using critical care nursing expertise in Denver, Colorado. An experienced CCRN-certified nurse manages the system 24 hours a day, 7 days a week, from Eastern Colorado Health Care System. The virtual ICU provides rapid response interventions through virtual technology. This tele-ICU technology allows for a "virtual handshake" by nursing staff at the start of the shift and a report on potential patient issues. Clinical relationships have been strengthened between all 5 VA facilities in the Rocky Mountain Region, increasing the likelihood of early consultation at the onset of clinical decline of a patient. In addition, the tele-ICU nurse is available for immediate nursing consultation and support, coordinates point-to-point virtual consultation between physicians at the rural sites and specialists in Denver, and assists in expediting critical care transfers. The primary objectives for the tele-ICU program include improving quality and access of care to critical care services in rural sites, reducing community fee basis costs and frequency of transfers, and increasing collaboration and collegiality among nursing and medical staff in all Region 19's medical centers.

Introduction Factors predictive of the need for red blood cell (RBC) transfusion in the intensive care unit (ICU) have been identified, but risk factors for transfusion after ICU discharge are unknown. This study aims identifies risk factors for RBC transfusion after discharge from the ICU. Methods A prospective, monocentric observational study was conducted over a 6-month period in a 24-bed medical ICU in a French university hospital. Between June and December 2003, 550 critically ill patients were consecutively enrolled in the study. Results A total of 428 patients survived after treatment in the ICU; 47 (11% of the survivors, 8.5% of the whole population) required RBC transfusion within 7 days after ICU discharge. Admission for sepsis (odds ratio [OR] 341.60, 95% confidence interval [CI] 20.35–5734.51), presence of an underlying malignancy (OR 32.6, 95%CI 3.8–280.1), female sex (OR 5.4, 95% CI 1.2–24.9), Logistic Organ Dysfunction score at ICU discharge (OR 1.45, 95% CI 1.1–1.9) and age (OR 1.06, 95% CI 1.02–1.12) were independently associated with RBC transfusion after ICU stay. Haemoglobin level at discharge predicted the need for delayed RBC transfusion. Use of vasopressors (OR 0.01, 95%CI 0.001–0.17) and haemoglobin level at discharge from the ICU (OR 0.02, 95% CI 0.007–0.09; P < 0.001) were strong independent predictors of transfusion of RBC 1 week after ICU discharge. Conclusion Sepsis, underlying conditions, unresolved organ failures and haemoglobin level at discharge were related to an increased risk for RBC transfusion after ICU stay. We suggest that strategies to prevent transfusion should focus on homogeneous subgroups of patients and take into account post-ICU needs for RBC transfusion. PMID:16965637

To determine whether the therapeutic intervention scoring system (TISS) reliably reflects the cost of the overall intensive care unit (ICU) population, subgroups of that population and individual ICU patients. Prospective analysis of individual patient costs and comparison with TISS. Adult, 12 bedded general medical and surgical ICU in a university teaching hospital. Two hundred fifty-seven consecutive patients including 52 coronary care (CCU), 99 cardiac surgery (CS) and 106 general ICU (GIC) cases admitted to the ICU during a 12-week period in 1994. A total of 916 TISS-scored patient days were analysed A variable cost (VC) that included consumables and service usage (nursing, physiotherapy, radiology and pathology staff costs) for individual patients was measured daily. Nursing costs were calculated in proportion to a daily nursing dependency score. A fixed cost (FC) was calculated for each patient to include medical, technical and clerical salary costs, capital equipment depreciation, equipment and central hospital costs. The correlation between cost and TISS was analysed using regression analysis. For the whole group (n = 257) the average daily FC was pound sterling 255 and daily VC was pound sterling 541 (SEM 10); range pound sterling 23-pound sterling 2,806. In the patient subgroups average daily cost (FC + VC) for CCU was pound sterling 476 (SEM 17.5), for CS pound sterling 766 (SEM 13.8) and for GIC pound sterling 873 (SEM 13.6). In the group as a whole, a strong correlation was demonstrated between VC and the TISS for each patient day (r = 0.87, p < 0.001) and this improved further when the total TISS score was compared with the total VC of the entire patient episode (r = 0.93, p < 0.001). This correlation was maintained in CCU, CS and GIC patient cohorts with only a small median difference between actual and predicted cost (2.2 % for GIC patients). However, in the individual patient, the range of error was up to +/- 65 % of the true variable cost. For the

In the ICU, discussions between clinicians and surrogate decision makers are often accompanied by conflict about a patient's prognosis or care plan. Trust plays a role in limiting conflict, but little is known about the determinants of trust in the ICU. We sought to identify the dimensions of trust and clinician behaviors conducive to trust formation in the ICU. Prospective qualitative study. Medical ICU of a major urban university hospital. Surrogate decision makers of intubated, mechanically ventilated patients in the medical ICU. Semistructured interviews focused on surrogates' general experiences in the ICU and on their trust in the clinicians caring for the patient. Interviews were audio-recorded, transcribed verbatim, and coded by two reviewers. Constant comparison was used to identify themes pertaining to trust. Thirty surrogate interviews revealed five dimensions of trust in ICU clinicians: technical competence, communication, honesty, benevolence, and interpersonal skills. Most surrogates emphasized the role of nurses in trust formation, frequently citing their technical competence. Trust in physicians was most commonly related to honesty and the quality of their communication with surrogates. Interventions to improve trust in the ICU should be role-specific, since surrogate expectations are different for physicians and nurses with regard to behaviors relevant to trust. Further research is needed to confirm our findings and explore the impact of trust modification on clinician-family conflict.

Background: No previous study has evaluated the association between admission to ICUs during round time and patient outcome. The objective of this study was to determine the association between round-time ICU admission and patient outcome. Methods: This retrospective study included 49,844 patients admitted from October 1994 to December 2007 to four ICUs (two surgical, one medical, and one multispecialty) of an academic medical center. Of these patients, 3,580 were admitted to the ICU during round time (8:00 am to 10:59 am) and 46,264 were admitted during nonround time (from 1:00 pm to 6:00 am). The medical ICU had 24-h/7-day per week intensivist coverage during the last 2 years of the study. We compared the baseline characteristics and outcome of patients admitted to the ICU between the two groups. Data were abstracted from the acute physiology and chronic health evaluation (APACHE) III database. Results: The round-time and non-round-groups were similar in gender, ethnicity, and age. The predicted hospital mortality rate of the round time group was higher (17.4% vs 12.3% predicted, respectively; p < 0.001). The hospital length of stay was similar between the two groups. The round-time group had a higher hospital mortality rate (16.2% vs 8.8%, respectively; p < 0.001). Most of the round-time ICU admissions and deaths occurred in the medical ICU. Round-time admission was an independent risk factor for hospital death (odds ratio, 1.321; 95% CI, 1.178 to 1.481). This independent association was present for the whole study period except for the last 2 years. Conclusions: Patients admitted to the ICU during morning rounds have higher severity of illness and mortality rates. PMID:19505985

Pharmacy-Driven Dexmedetomidine Stewardship and Appropriate Use Guidelines in a Community Hospital Setting.

Dexmedetomidine is a widely utilized agent in the intensive care unit (ICU) because it does not suppress respiratory drive and may be associated with less delirium than midazolam or propofol. Cost of dexmedetomidine therapy and debate as to the proper duration of use has brought its use to the forefront of discussion. To validate the efficacy and cost savings associated with pharmacy-driven dexmedetomidine appropriate use guidelines and stewardship in mechanically ventilated patients. This was a retrospective cohort study of adult patients who received dexmedetomidine for ICU sedation while on mechanical ventilation at a 433-bed not-for-profit community hospital. Included patients were divided into pre-enactment (PRE) and postenactment (POST) of dexmedetomidine guideline groups. A total of 100 patients (50 PRE and 50 POST) were included in the analysis. A significant difference in duration of mechanical ventilation (11.1 vs 6.2 days, P = 0.006) and incidence of reintubation (36% vs 18% of patients, P = 0.043) was seen in the POST group. Aggregate use of dexmedetomidine 200-µg vials (37.1 vs 18.4 vials, P = 0.010) and infusion days (5.4 vs 2.5 days, P = 0.006) were significantly lower in the POST group. Dexmedetomidine acquisition cost savings were calculated at $374 456.15 in the POST group. There was no difference between the PRE and POST groups with regard to ICU length of stay, expected mortality, and observed mortality. Pharmacy-driven dexmedetomidine appropriate use guidelines decreased the use of dexmedetomidine and increased cost savings at a community hospital without adversely affecting clinical outcomes.

This study evaluates rural hospital staff perceptions of a telemedicine ICU (Tele-ICU) before and after implementation. We conducted a longitudinal qualitative study utilising semistructured group or individual interviews with staff from three rural ICU facilities in the upper Midwest of the United States that received Tele-ICU support. Interviews occurred pre-implementation and at two time points post-implementation. Interviews were conducted with: ICU administrators (n=6), physicians (n=3), nurses (n=9), respiratory therapists (n=5) and other (n=1) from July 2011 to May 2013. Transcripts were analysed for thematic content. Overall, rural ICU staff viewed Tele-ICU as a welcome benefit for their facility. Major themes included: (1) beneficial where recruitment and retention of staff can be challenging; (2) extra support for day shifts and evening, night and weekend shifts; (3) reduction in the number of transfers larger tertiary hospitals in the community; (4) improvement in standardisation of care; and (5) organisational culture of rural ICUs may lead to under-utilisation. ICU staff at rural facilities view Tele-ICU as a positive, useful tool to provide extra support and assistance. However, more research is needed regarding organisational culture to maximise the potential benefits of Tele-ICU in rural hospitals. Published by Elsevier Ltd.

The discharge letter is the primary means of communication at patient discharge, yet discharge letters are often not completed on time. A multifaceted intervention was performed to improve communication in patient hand-off from the intensive care unit (ICU) to the wards by improving the timeliness of discharge letters. A management directive was operationalised by a working group of ICU staff in a longitudinal before-after study. The intervention consisted of (a) changing policy to require a letter for use as a transfer note at the time of ICU discharge, (b) changing the assignment of responsibility to an automatic process, (c) leveraging positive peer pressure by making the list of patients in need of letters visible to colleagues and (d) provision of decision support, through automatic copying of important content from the patient record to the letter and email reminders if letters were not written on time. Statistical process control charts were used to monitor the longitudinal effect of the intervention. The intervention resulted in a 77.9% absolute improvement in the proportion of patients with a complete transfer note at the time of discharge, and an 85.2% absolute improvement in the number of discharge letters written. Statistical process control shows that the effect was sustained over time. A multifaceted intervention can be highly effective for improving discharge communication from the ICU.

To explore the issues surrounding privacy during death in ICU. While the provision of ICU care is vital, the nature and effect of the potential lack of privacy during death and dying in ICUs have not been extensively explored. A literature search using CINAHL and Pubmed revealed articles related to privacy, death and dying in ICU. Keywords used in the search were "ICU," "Privacy," "Death" and "Dying." A combination of these terms using Boolean operators "or" or "and" revealed a total of 23 citations. Six papers were ultimately deemed suitable for inclusion in the review and were subjected to code analysis with Atlas.ti v8 QDA software. The analysis of the studies revealed eight themes, and this study presents the three key themes that were found to be recurring and strongly interconnected to the experience of privacy and death in ICU: "Privacy in ICU," "ICU environment" and "End-of-Life Care". Research has shown that patient and family privacy during the ICU hospitalisation and the provision of the circumstances that lead to an environment of privacy during and after death remains a significant challenge for ICU nurses. Family members have little or no privacy in shared room and cramped waiting rooms, while they wish to be better informed and involved in end-of-life decisions. Hence, death and dying for many patients takes place in open and/or shared spaces which is problematic in terms of both the level of privacy and respect that death ought to afford. It is best if end-of-life care in the ICU is planned and coordinated, where possible. Nurses need to become more self-reflective and aware in relation to end-of-life situations in ICU in order to develop privacy practices that are responsive to family and patient needs. © 2018 John Wiley & Sons Ltd.

Identifying Elements of ICU Care That Families Report as Important But Unsatisfactory

Osborn, Tristan R.; Curtis, J. Randall; Nielsen, Elizabeth L.; Back, Anthony L.; Shannon, Sarah E.

2012-01-01

Background: One in five deaths in the United States occurs in the ICU, and many of these deaths are experienced as less than optimal by families of dying people. The current study investigated the relationship between family satisfaction with ICU care and overall ratings of the quality of dying as a means of identifying targets for improving end-of-life experiences for patients and families. Methods: This multisite cross-sectional study surveyed families of patients who died in the ICU in one of 15 hospitals in western Washington State. Measures included the Family Satisfaction in the ICU (FS-ICU) and the Single-Item Quality of Dying (QOD-1) questionnaires. Associations between FS-ICU items and the QOD-1 were examined using multivariate linear regression controlling for patient and family demographics and hospital site. Results: Questionnaires were returned for 1,290 of 2,850 decedents (45%). Higher QOD-1 scores were significantly associated (all P < .05) with (1) perceived nursing skill and competence (β = 0.15), (2) support for family as decision-makers (β = 0.10), (3) family control over the patient’s care (β = 0.18), and (4) ICU atmosphere (β = 0.12). FS-ICU items that received low ratings and correlated with higher QOD-1 scores (ie, important items with room for improvement) were (1) support of family as decision-maker, (2) family control over patient’s care, and (3) ICU atmosphere. Conclusions: Increased support for families as decision-makers and for their desired level of control over patient care along with improvements in the ICU atmosphere were identified as aspects of the ICU experience that may be important targets for quality improvement.

The data of this initiative called "nutritionDay ICU" were analyzed. A questionnaire translated in 17 languages was used to determine the unit's characteristics, patient's condition, nutrition condition and therapy as well as outcome. All the patients present in the morning of the 1 day prevalence study were included from 2007 to 2013. 9777 patients from 46 countries and 880 units were included. Their SAPS 2 was median 38 (IQR 27-51), predicted mortality was 30.7% ± 26.9, and their SOFA score 4.5 ± 3.4 with median 4 (IQR 2-7). Administration of calories did not appear to be related to actual or ideal body weight within all BMI groups. Patients with a BMI <18.5 or >40 received slightly less calories than all other BMI groups. Two third of the patients were either ventilated or were in the ICU for longer than 24 h at nutritionDay. Routes of feeding used were the oral, enteral and parenteral routes. More than 40% of the patients were not fed during the first day. The mean energy administered using enteral route was 1286 ± 663 kcal/day and using parenteral nutrition 1440 ± 652 kcal/day. 60 days mortality was 26.0%. This very large collaborative cohort study shows that most of the patients are underfed during according to actual recommendations their ICU stay. Prescribed calories appear to be ordered regardless to the ideal weight of the patient. Nutritional support is slow to start and never reaches the recommended targets. Parenteral nutrition prescription is increasing during the ICU stay but reaching only 20% of the population studied if ICU stay is one week or longer. The nutritional support worldwide does not seem to be guided by weight or disease but more to be standardized and limited to a certain level of calories. These observations are showing the poor observance to

To describe direct medical costs of influenza in hospitalized elderly, with and without intensive care unit (ICU) admission, during the 2014-2015 season in Hong Kong. A retrospective study was conducted in 110 inpatients aged ≥65 years with laboratory-confirmed influenza treated by antiviral therapy during season 2014-2015 in a tertiary hospital. Resource utilization of influenza-related diagnostic and laboratory tests, medications for influenza treatment, usage of general medical ward and ICU during the influenza-related length of hospital stay (IR-LOS) were collected. There were 18 (16.4%) and 92 (83.4%) cases with and without ICU admission, respectively. The difference in influenza-related mortality rates between patients with (11.1%) and without ICU admission (2.2%) was not statistically significant (P=0.064). Patients with ICU admission reported longer IR-LOS (12.7 ±6.0 days versus 5.5 ±2.7 days; P<0.001) and higher direct costs (36,588 USD ±21,482 versus 5,773 USD ±2,017; P<0.001; 1 USD=7.8 HKD). Male gender (OR=14.50; 95% CI 1.68, 125.07) and respiratory complications (OR=9.61; 95% CI 1.90, 48.50) were positive predictors of ICU admission. Age ≥70 years (OR=0.09; 95% CI 0.02, 0.46) and antiviral therapy initiation within 7 days (OR=0.05; 95% CI 0.003, 0.79) were negative predictors of ICU admission. Influenza B was a positive predictor of high-cost hospitalization in non-ICU survivors (OR=7.33; 95% CI 1.24, 43.29). No predictor of mortality was identified. Hospitalization cost in elderly for seasonal influenza was substantial in Hong Kong. The cost in patients with ICU admission was significantly higher than those without ICU care. Respiratory complications and male gender predicted ICU admission. Influenza B infection predicted high-cost hospitalization in non-ICU survivors.

Objective In the ICU, discussions between clinicians and surrogate decision makers are often accompanied by conflict about a patient’s prognosis or care plan. Trust plays a role in limiting conflict, but little is known about the determinants of trust in the ICU. We sought to identify the dimensions of trust and clinician behaviors conducive to trust formation in the ICU. Design Prospective qualitative study. Setting Medical ICU of a major urban university hospital. Subjects Surrogate decision makers of intubated, mechanically ventilated patients in the medical ICU. Measurements and Main Results Semistructured interviews focused on surrogates’ general experiences in the ICU and on their trust in the clinicians caring for the patient. Interviews were audio-recorded, transcribed verbatim, and coded by two reviewers. Constant comparison was used to identify themes pertaining to trust. Thirty surrogate interviews revealed five dimensions of trust in ICU clinicians: technical competence, communication, honesty, benevolence, and interpersonal skills. Most surrogates emphasized the role of nurses in trust formation, frequently citing their technical competence. Trust in physicians was most commonly related to honesty and the quality of their communication with surrogates. Conclusions Interventions to improve trust in the ICU should be role-specific, since surrogate expectations are different for physicians and nurses with regard to behaviors relevant to trust. Further research is needed to confirm our findings and explore the impact of trust modification on clinician-family conflict. PMID:27513360

To assess the cost effectiveness of an initial ICU admissionforpatients with severe sepsis or those in septic shock following the initial resuscitation in the emergency department. Mortality data was generated through retrospective data obtained from 1,048 adult patients with severe sepsis or in septic shock from one tertiary care and eight community hospitals in Phitsanulok during the period of October 2010 to September 2011. These patients were categorized into two groups; as either admitted from the emergency department directly to the ICU (stated as an immediate ICU admission) or admitted from the emergency department to the general hospital ward due to an unavailability of lCU beds (stated as a delayed ICU admission). The overall direct costs and characteristics were simulated from a second group of 994 adult patients, admitted a year later from selected data by the ICD-10 codes [International Classification of Diseases, 10th edition] with the same conditions of severe sepsis and septic shock (September 2011 through September 2012), as there was no collection of costs and characteristics during the first period (October 2010 through September 2011). A decision tree model and an incremental cost-effectiveness ratio (ICER) were used for the analyses of the cost-effectiveness. There were no significant differences in either the mean ages or lengths of stay between both groups. All-cause mortality rates have shown an incidence of 22.2% for the immediate ICU admission group and an incidence of 46.3% in the delayed ICUadmission group (odds ratio for the immediate ICU admission group was 0. 479 with a 95% confidence interval, 0.376-0.611). Total costs (mean, 95% CI) of the immediate ICUadmission group [37,194 baht (32,389-44,926)] were higher than had been seen in the delayed ICU admission group [26,275 (24,300-27,936)]. Incremental cost was 10,919 baht. ICER for the immediate ICU admission group was 45,307 baht per life saved. Immediate ICU admission for patients

To evaluate the potential annual net cost savings of implementing an ICU early rehabilitation program. Using data from existing publications and actual experience with an early rehabilitation program in the Johns Hopkins Hospital Medical ICU, we developed a model of net financial savings/costs and presented results for ICUs with 200, 600, 900, and 2,000 annual admissions, accounting for both conservative- and best-case scenarios. Our example scenario provided a projected financial analysis of the Johns Hopkins Medical ICU early rehabilitation program, with 900 admissions per year, using actual reductions in length of stay achieved by this program. U.S.-based adult ICUs. Financial modeling of the introduction of an ICU early rehabilitation program. Net cost savings generated in our example scenario, with 900 annual admissions and actual length of stay reductions of 22% and 19% for the ICU and floor, respectively, were $817,836. Sensitivity analyses, which used conservative- and best-case scenarios for length of stay reductions and varied the per-day ICU and floor costs, across ICUs with 200-2,000 annual admissions, yielded financial projections ranging from -$87,611 (net cost) to $3,763,149 (net savings). Of the 24 scenarios included in these sensitivity analyses, 20 (83%) demonstrated net savings, with a relatively small net cost occurring in the remaining four scenarios, mostly when simultaneously combining the most conservative assumptions. A financial model, based on actual experience and published data, projects that investment in an ICU early rehabilitation program can generate net financial savings for U.S. hospitals. Even under the most conservative assumptions, the projected net cost of implementing such a program is modest relative to the substantial improvements in patient outcomes demonstrated by ICU early rehabilitation programs.

Because of around-the-clock activities, environmental noise and light are among the many causes of sleep disturbance in an intensive care unit (ICU). The implementation of guidelines may potentially change behavior rules and improve sleep quality. A prospective interventional study, observing the effects of simple nighttime guidelines on light and noise levels in an ICU. A modern surgical ICU, subdivided into six identical three-bed rooms. Critically ill adult patients. Between two observation periods, five guidelines were implemented to decrease both light and noise during the night shift in the patient's room. Light levels and noise levels were obtained using a luxmeter and a sound level meter [A-weighted decibels (dB) scale] and were monitored continuously from 11 pm to 5 am both before (period P1) and after (period P2) the implementation of guidelines. Similar patient's gravity and nursing workload scores were observed between P1 and P2. A low mean (<5 Lux) and maximal light level were measured during both P1 and P2. The implementation of guidelines lowered mean light disturbance intensity with a greater variability of light during P2. All noise levels were high and corresponded more to a quiet office for noise level equivalents and to a busy restaurant for peak noise levels during both P1 and P2. Guidelines decreased the noise level equivalent (P1, 51.3 dB; P2, 48.3 dB), peak noise level (P1, 74.9 dB; P2, 70.8 dB), and the number of acoustic identified alarms (P1, 22.1 dB; P2, 15.8 dB) during P2. The night light levels were low during both periods, and lowering the light levels induced a greater variation of light, which may impair sleep quality. All measured noise levels were high during both periods, which could contribute to sleep disturbance, and the implementation of guidelines significantly lowers some important noise levels. The background noise level was unchanged.

The aim of this study was to describe the contents of a patient diary and its significance for persons cared for in an ICU. An empirical study with a qualitative design. Eight telephone interviews and one face-to-face interview were conducted with nine persons previously been treated in an ICU and been given a patient diary. In addition, the person would have read his/her diary. The data have been analysed with qualitative content analysis. The study identified one overarching theme; Gaining understanding, and four categories; The diary is written for me, Creating memories from the time of care, Who writes in the diary and, The ability to return to the diary. The diary meant that participants gained an understanding of their time in the ICU while they were critically ill and the diary was important to be able to return to. What formerly critically ill patients appreciate most about the diary is that the diary is personally written, which makes them feel confirmed and valuable as a person. Guidelines for how and when a diary should be written and used would likely encourage critical care nurses and relatives to write in it. Copyright © 2017 Elsevier Ltd. All rights reserved.

Measuring tele-ICU impact: does it optimize quality outcomes for the critically ill patient?

Goran, Susan F

2012-04-01

To determine the relationship between tele-ICU (intensive care unit) implementations and improvement in quality measures and patient outcomes. Tele-ICUs were designed to leverage scarce critical-care experts and promised to improve patient quality. Abstracts and peer-reviewed articles were reviewed to identify the associations between tele-ICU programmes and clinical outcomes, cost savings, and customer satisfaction. Few peer-reviewed studies are available and many variables in each study limit the ability to associate study conclusions to the overall tele-ICU programme. Further research is required to explore the impact of the tele-ICU on patient/family satisfaction. Research findings are highly dependent upon the level of ICU acceptance. The tele-ICU, in collaboration with the ICU team, can be a valuable tool for the enhancement of quality goals although the ability to demonstrate cost savings is extremely complex. Studies clearly indicate that tele-ICU nursing vigilance can enhance patient safety by preventing potential patient harm. Nursing managers and leaders play a vital part in optimizing the quality role of the tele-ICU through supportive modelling and the maximization of ICU integration. © 2012 Blackwell Publishing Ltd.

The ICU is a complex and stressful environment and is associated with significant psychologic morbidity for patients and their families. We sought to determine whether salivary cortisol, a physiologic measure of acute stress, was associated with subsequent psychologic distress among family members of ICU patients. This is a prospective, observational study of family members of adult ICU patients. Adult medical and surgical ICU in a tertiary care center. Family members of ICU patients. Participants provided five salivary cortisol samples over 24 hours at the time of the patient ICU admission. The primary measure of cortisol was the area under the curve from ground; the secondary measure was the cortisol awakening response. Outcomes were obtained during a 3-month follow-up telephone call. The primary outcome was anxiety, measured by the Hospital Anxiety and Depression Scale-Anxiety. Secondary outcomes included depression and posttraumatic stress disorder. Among 100 participants, 92 completed follow-up. Twenty-nine participants (32%) reported symptoms of anxiety at 3 months, 15 participants (16%) reported depression symptoms, and 14 participants (15%) reported posttraumatic stress symptoms. In our primary analysis, cortisol level as measured by area under the curve from ground was not significantly associated with anxiety (odds ratio, 0.94; p = 0.70). In our secondary analysis, however, cortisol awakening response was significantly associated with anxiety (odds ratio, 1.08; p = 0.02). Roughly one third of family members experience anxiety after an ICU admission for their loved one, and many family members also experience depression and posttraumatic stress. Cortisol awakening response is associated with anxiety in family members of ICU patients 3 months following the ICU admission. Physiologic measurements of stress among ICU family members may help identify individuals at particular risk of adverse psychologic outcomes.

The objectives of this study were to develop a scale for measuring the highest level of mobility in adult ICU patients and to assess its feasibility and inter-rater reliability. Growing evidence supports the feasibility, safety and efficacy of early mobilization in the intensive care unit (ICU). However, there are no adequately validated tools to quickly, easily, and reliably describe the mobility milestones of adult patients in ICU. Identifying or developing such a tool is a priority for evaluating mobility and rehabilitation activities for research and clinical care purposes. This study was performed at two ICUs in Australia. Thirty ICU nursing, and physiotherapy staff assessed the feasibility of the 'ICU Mobility Scale' (IMS) using a 10-item questionnaire. The inter-rater reliability of the IMS was assessed by 2 junior physical therapists, 2 senior physical therapists, and 16 nursing staff in 100 consecutive medical, surgical or trauma ICU patients. An 11 point IMS scale was developed based on multidisciplinary input. Participating clinicians reported that the scale was clear, with 95% of respondents reporting that it took <1 min to complete. The junior and senior physical therapists showed the highest inter-rater reliability with a weighted Kappa (95% confidence interval) of 0.83 (0.76-0.90), while the senior physical therapists and nurses and the junior physical therapists and nurses had a weighted Kappa of 0.72 (0.61-0.83) and 0.69 (0.56-0.81) respectively. The IMS is a feasible tool with strong inter-rater reliability for measuring the maximum level of mobility of adult patients in the ICU. Copyright © 2014 Elsevier Inc. All rights reserved.

Delirium is an acute disturbance of consciousness and cognition. It is a common disorder in the intensive care unit (ICU) and associated with impaired long-term outcome. Despite its frequency and impact, delirium is poorly recognized by ICU-physicians and -nurses using delirium screening tools. A completely new approach to detect delirium is to use monitoring of physiological alterations. Temperature variability, a measure for temperature regulation, could be an interesting component to monitor delirium, but whether temperature regulation is different during ICU delirium has not yet been investigated. The aim of this study was to investigate whether ICU delirium is related to temperature variability. Furthermore, we investigated whether ICU delirium is related to absolute body temperature. We included patients who experienced both delirium and delirium free days during ICU stay, based on the Confusion Assessment method for the ICU conducted by a research- physician or -nurse, in combination with inspection of medical records. We excluded patients with conditions affecting thermal regulation or therapies affecting body temperature. Daily temperature variability was determined by computing the mean absolute second derivative of the temperature signal. Temperature variability (primary outcome) and absolute body temperature (secondary outcome) were compared between delirium- and non-delirium days with a linear mixed model and adjusted for daily mean Richmond Agitation and Sedation Scale scores and daily maximum Sequential Organ Failure Assessment scores. Temperature variability was increased during delirium-days compared to days without delirium (β(unadjuste)d=0.007, 95% confidence interval (CI)=0.004 to 0.011, p<0.001). Adjustment for confounders did not alter this result (β(adjusted)=0.005, 95% CI=0.002 to 0.008, p<0.001).

Tools for predicting post-ICU patients' outcomes are scarce. A single-center study showed that the Sabadell score classified patients into four groups with clear-cut differences in ward mortality. To validate the Sabadell score using a prospective multicenter approach. Thirty-one ICUs in Spain. All patients admitted in the 3-month study period. We recorded variables at ICU admission (age, sex, severity of illness, and do-not-resuscitate orders), during the ICU stay (ICU-specific treatments, ICU-acquired infection, and acute renal failure), and at ICU discharge (Sabadell score). Statistical analyses included one-way ANOVA and multiple regression analysis with ward mortality as the dependent variable. We admitted 4,132 patients (mean age 61.5 +/- 16.7 years) with mean predicted mortality of 23.8 +/- 22.7%; 545 patients (13%) died in the ICU and 3,587 (87%) were discharged to the ward. Overall ward mortality was 6.7%; ward mortality was 1.5% (36/2,422) in patients with score 0 (good prognosis), 9% (64/725) in patients with score 1 (long-term poor prognosis), 23% (79/341) in patients with score 2 (short-term poor prognosis), and 64% (63/99) in patients with score 3 (expected hospital death). Variables associated with ward mortality in the multivariate analysis were predicted risk of death (OR 1.016), ICU readmission (OR 5.9), Sabadell score 1 (OR 4.7), Sabadell score 2 (OR 15.7), and Sabadell score 3 (OR 107.2). We confirm the ability of the Sabadell score at ICU discharge to define four groups of patients with very different likelihoods of hospital survival.

A comprehensive preoperative evaluation is critical for providing anesthetic care for patients from the intensive care unit (ICU). There has been no preoperative evaluation form specific for ICU patients that allows for a rapid and focused evaluation by anesthesia providers, including junior residents. In this study, a specific preoperative form was designed for ICU patients and evaluated to allow residents to perform the most relevant and important preoperative evaluations efficiently. The following steps were utilized for developing the preoperative evaluation form: 1) designed a new preoperative form specific for ICU patients; 2) had the form reviewed by attending physicians and residents, followed by multiple revisions; 3) conducted test releases and revisions; 4) released the final version and conducted a survey; 5) compared data collection from new ICU form with that from a previously used generic form. Each piece of information on the forms was assigned a score, and the score for the total missing information was determined. The score for each form was presented as mean ± standard deviation (SD), and compared by unpaired t test. A P value < 0.05 was considered statistically significant. Of 52 anesthesiologists (19 attending physicians, 33 residents) responding to the survey, 90% preferred the final new form; and 56% thought the new form would reduce perioperative risk for ICU patients. Forty percent were unsure whether the form would reduce perioperative risk. Over a three month period, we randomly collected 32 generic forms and 25 new forms. The average score for missing data was 23 ± 10 for the generic form and 8 ± 4 for the new form (P = 2.58E-11). A preoperative evaluation form designed specifically for ICU patients is well accepted by anesthesia providers and helped to reduce missing key preoperative information. Such an approach is important for perioperative patient safety.

Sepsis 2018: Definitions and Guideline Changes.

PubMed

Napolitano, Lena M

Sepsis is a global healthcare issue and continues to be the leading cause of death from infection. Early recognition and diagnosis of sepsis is required to prevent the transition into septic shock, which is associated with a mortality rate of 40% or more. New definitions for sepsis and septic shock (Third International Consensus Definitions for Sepsis and Septic Shock [Sepsis-3]) have been developed. A new screening tool for sepsis (quick Sequential Organ Failure Assessment [qSOFA]) has been proposed to predict the likelihood of poor outcome in out-of-intensive care unit (ICU) patients with clinical suspicion of sepsis. The Surviving Sepsis Campaign Guidelines were recently updated and include greater evidence-based recommendations for treatment of sepsis in attempts to reduce sepsis-associated mortality. This review discusses the new Sepsis-3 definitions and guidelines.

Clinicians in the neonatal ICU must engage in clear and compassionate communication with families. Empirical, observational studies of neonatal ICU family conferences are needed to develop counseling best practices and to train clinicians in key communication skills. We devised a pilot study to record and analyze how interdisciplinary neonatal ICU clinicians and parents navigate difficult conversations during neonatal ICU family conferences. We prospectively identified and audiotaped a convenience sample of neonatal ICU family conferences about "difficult news." Conversations were analyzed using the Roter interaction analysis system, a quantitative tool for assessing content and quality of patient-provider communication. An urban academic children's medical center with a 45-bed level IV neonatal ICU. Neonatal ICU parents and clinicians. None. We analyzed 19 family conferences that included 31 family members and 23 clinicians. The child's mother was included in all conferences, and a second parent, usually the father, was present in 13 conferences. All but one conference included multiple medical team members. On average, physicians contributed 65% of all dialogue, regardless of who else was present. Over half (56%) of this dialogue involved giving medical information; under 5% of clinician dialogue involved asking questions of the family, and families rarely (5% of dialogue) asked questions. Conversations were longer with the presence of nonphysician clinicians, but this did not increase the amount of dialogue about psychosocial information or increase parent dialogue. We collected a novel repository of audio-recorded neonatal ICU family meetings that offers insights into discussion content and process. These meetings were heavily focused on biomedical information even when interdisciplinary clinicians were present. Clinicians always talked more than parents, and no one asked many questions.

The introduction of electronic medical records (EMR) and computerized physician order entry (CPOE) into the intensive care unit (ICU) is transforming the way health care providers currently work. The challenge facing developers of EMR’s is to create products which add value to systems of health care delivery. As EMR’s become more prevalent, the potential impact they have on the quality and safety, both negative and positive, will be amplified. In this paper we outline the key barriers to effective use of EMR and describe the methodology, using a worked example of the output. AWARE (Ambient Warning and Response Evaluation), is a physician led, electronic-environment enhancement program in an academic, tertiary care institution’s ICU. The development process is focused on reducing information overload, improving efficiency and eliminating medical error in the ICU. PMID:23616831

Few data are available regarding the epidemiology of invasive aspergillosis (IA) in ICU patients. The aim of this study was to examine epidemiology and economic outcomes (length of stay, hospital costs) among ICU patients with IA who lack traditional risk factors for IA, such as cancer, transplants, neutropenia or HIV infection. Retrospective cohort study using Premier Inc. Perspective™ US administrative hospital database (2005-2008). Adults with ICU stays and aspergillosis (ICD-9 117.3 plus 484.6) who received initial antifungal therapy (AF) in the ICU were included. Patients with traditional risk factors (cancer, transplant, neutropenia, HIV/AIDS) were excluded. The relationship of antifungal therapy and co-morbidities to economic outcomes were examined using Generalized linear models. From 6,424 aspergillosis patients in the database, 412 (6.4%) ICU patients with IA were identified. Mean age was 63.9 years and 53% were male. Frequent co-morbidities included steroid use (77%), acute respiratory failure (76%) and acute renal failure (41%). In-hospital mortality was 46%. The most frequently used AF was voriconazole (71% received at least once). Mean length of stay (LOS) was 26.9 days and mean total hospital cost was $76,235. Each 1 day lag before initiating AF therapy was associated with 1.28 days longer hospital stay and 3.5% increase in costs (p < 0.0001 for both). Invasive aspergillosis in ICU patients is associated with high mortality and hospital costs. Antifungal timing impacts economic outcomes. These findings underscore the importance of timely diagnosis, appropriate treatment, and consideration of Aspergillus as a potential etiology in ICU patients.

The 2015 sepsis definitions suggest using the quick SOFA score for risk stratification of sepsis patients among other changes in sepsis definition. Our aim was to validate the q sofa score for diagnosing sepsis and comparing it to traditional scores of pre ICU admission sepsis outcome prediction such as EWS and SIRS in our setting in order to predict mortality and length of stay. This was a retrospective cohort study. We retrospectively calculated the q sofa, SIRS and EWS scores of all ICU patients admitted with the diagnosis of sepsis at our center in 2015. This was analysed using STATA 12. Logistic regression and ROC curves were used for analysis in addition to descriptive analysis. 58 patients were included in the study. Based on our one year results we have shown that although q SOFA is more sensitive in predicting LOS in ICU of sepsis patients, the EWS score is more sensitive and specific in predicting mortality in the ICU of such patients when compared to q SOFA and SIRS scores. In conclusion, we find that in our setting, EWS is better than SIRS and q SOFA for predicting mortality and perhaps length of stay as well. The q Sofa score remains validated for diagnosis of sepsis.

Intensive Care Units (ICU) are costly yet critical hospital departments that should be available to care for patients needing highly specialized critical care. Shortage of ICU beds in many regions of the world and the constant fire-fighting to make these beds available through various ICU management policies motivated this study. The paper discusses the application of a generic system dynamics model of emergency patient flow in a typical hospital, populated with empirical evidence found in the medical and hospital administration literature, to explore the dynamics of intended and unintended consequences of such ICU management policies under a natural disaster crisis scenario. ICU management policies that can be implemented by a single hospital on short notice, namely premature transfer from ICU, boarding in ward, and general ward admission control, along with their possible combinations, are modeled and their impact on managerial and health outcome measures are investigated. The main insight out of the study is that the general ward admission control policy outperforms the rest of ICU management policies under such crisis scenarios with regards to reducing total mortality, which is counter intuitive for hospital administrators as this policy is not very effective at alleviating the symptoms of the problem, namely high ED and ICU occupancy rates that are closely monitored by hospital management particularly in times of crisis. A multivariate sensitivity analysis on parameters with diverse range of values in the literature found the superiority of the general ward admission control to hold true in every scenario.

Tele-ICU and Patient Safety Considerations.

PubMed

Hassan, Erkan

The tele-ICU is designed to leverage, not replace, the need for bedside clinical expertise in the diagnosis, treatment, and assessment of various critical illnesses. Tele-ICUs are primarily decentralized or centralized models with differing advantages and disadvantages. The centralized model has sufficiently powered published data to be associated with improved mortality and ICU length of stay in a cost-effective manner. Factors associated with improved clinical outcomes include improved compliance with best practices; providing off-hours implementation of the bedside physician's care plan; and identification of and rapid response to physiological instability (initial clinical review within 1 hour) and rapid response to alerts, alarms, or direct notification by bedside clinicians. With improved communication and frequent review of patients between the tele-ICU and the bedside clinicians, the bedside clinician can provide the care that only they can provide. Although technology continues to evolve at a rapid pace, technology alone will most likely not improve clinical outcomes. Technology will enable us to process real or near real-time data into complex and powerful predictive algorithms. However, the remote and bedside teams must work collaboratively to develop care processes to better monitor, prioritize, standardize, and expedite care to drive greater efficiencies and improve patient safety.

With growing awareness of the importance of rehabilitation, new measures are being developed specifically for use in the intensive care unit (ICU). There are currently 26 measures reported to assess function in ICU survivors. The Physical Function in Intensive care Test scored (PFIT-s) has established clinimetric properties. It is unknown how other functional measures perform in comparison to the PFIT-s or which functional measure may be the most clinically applicable for use within the ICU. The aims of this study were to determine (1) the criterion validity of the Functional Status Score for the ICU (FSS-ICU), ICU Mobility Scale (IMS) and Short Physical Performance Battery (SPPB) against the PFIT-s; (2) the construct validity of these tests against muscle strength; (3) predictive utility of these tests to predict discharge to home; and (4) the clinical applicability. This was a nested study within an ongoing controlled study and an observational study. Sixty-six individuals were assessed at awakening and ICU discharge. Measures included: PFIT-s, FSS-ICU, IMS and SPPB. Bivariate relationships (Spearman's rank correlation coefficient) and predictive validity (logistic regression) were determined. Responsiveness (effect sizes); floor and ceiling effects; and minimal important differences were calculated. Mean ± SD PFIT-s at awakening was 4.7 ± 2.3 out of 10. On awakening a large positive relationship existed between PFIT-s and the other functional measures: FSS-ICU (rho = 0.87, p < 0.005), IMS (rho = 0.81, p < 0.005) and SPPB (rho = 0.70, p < 0.005). The PFIT-s had excellent construct validity (rho = 0.8, p < 0.005) and FSS-ICU (rho = 0.69, p < 0.005) and IMS (rho = 0.57, p < 0.005) had moderate construct validity with muscle strength. The PFIT-s and FSS-ICU had small floor/ceiling effects <11% at awakening and ICU discharge. The SPPB had a large floor effect at awakening (78%) and ICU discharge (56%). All

To assess the impact on ICU performance of a modular training program in three resource-limited general adult ICUs in India, Bangladesh, and Nepal. A modular ICU training programme was evaluated using performance indicators from June 2009 to June 2012 using an interrupted time series design with an 8 to 15 month pre-intervention and 18 to 24 month post-intervention period. ICU physicians and nurses trained in Europe and the USA provided training for ICU doctors and nurses. The training program consisted of six modules on basic intensive care practices of 2-3 weeks each over 20 months. The performance indicators consisting of ICU mortality, time to ICU discharge, rate at which patients were discharged alive from the ICU, discontinuation of mechanical ventilation or vasoactive drugs and duration of antibiotic use were extracted. Stepwise changes and changes in trends associated with the intervention were analysed. Pre-Training ICU mortality in Rourkela (India), and Patan (Nepal) Chittagong (Bangladesh), was 28%, 41% and 62%, respectively, compared to 30%, 18% and 51% post-intervention. The intervention was associated with a stepwise reduction in cumulative incidence of in-ICU mortality in Chittagong (adjusted subdistribution hazard ratio [aSHR] (95% CI): 0.62 (0.40, 0.97), p = 0.03) and Patan (aSHR 0.16 (0.06, 0.41), p<0.001), but not in Rourkela (aSHR: 1.17 (0.75, 1.82), p = 0.49). The intervention was associated with earlier discontinuation of vasoactive drugs at Rourkela (adjusted hazard ratio for weekly change [aHR] 1.08 (1.03, 1.14), earlier discontinuation of mechanical ventilation in Chittagong (aHR 2.97 (1.24, 7.14), p = 0.02), and earlier ICU discharge in Patan (aHR 1.87 (1.02, 3.43), p = 0.04). This structured training program was associated with a decrease in ICU mortality in two of three sites and improvement of other performance indicators. A larger cluster randomised study assessing process outcomes and longer-term indicators is warranted.

Utility of the PRE-DELIRIC delirium prediction model in a Scottish ICU cohort.

2016-08-01

The PREdiction of DELIRium for Intensive Care (PRE-DELIRIC) model reliably predicts at 24 h the development of delirium during intensive care admission. However, the model does not take account of alcohol misuse, which has a high prevalence in Scottish intensive care patients. We used the PRE-DELIRIC model to calculate the risk of delirium for patients in our ICU from May to July 2013. These patients were screened for delirium on each day of their ICU stay using the Confusion Assessment Method for ICU (CAM-ICU). Outcomes were ascertained from the national ICU database. In the 39 patients screened daily, the risk of delirium given by the PRE-DELIRIC model was positively associated with prevalence of delirium, length of ICU stay and mortality. The PRE-DELIRIC model can therefore be usefully applied to a Scottish cohort with a high prevalence of substance misuse, allowing preventive measures to be targeted.

Stressful patient experiences during the intensive care unit (ICU) stay is associated with reduced satisfaction in High Income Countries (HICs) but has not been explored in Lower and Middle Income Countries (LMICs). This study describes the recalled experiences, stress and satisfaction as perceived by survivors of ICUs in a LMIC. This follow-up study was carried out in 32 state ICUs in Sri Lanka between July and December 2015.ICU survivors' experiences, stress factors encountered and level of satisfaction were collected 30 days after ICU discharge by a telephone questionnaire adapted from Granja and Wright. Of 1665 eligible ICU survivors, 23.3% died after ICU discharge, 49.1% were uncontactable and 438 (26.3%) patients were included in the study. Whilst 78.1% (n = 349) of patients remembered their admission to the hospital, only 42.3% (n = 189) could recall their admission to the ICU. The most frequently reported stressful experiences were: being bedridden (34.2%), pain (34.0%), general discomfort (31.7%), daily needle punctures (32.9%), family worries (33.6%), fear of dying and uncertainty in the future (25.8%). The majority of patients (376, 84.12%) found the atmosphere of the ICU to be friendly and calm. Overall, the patients found the level of health care received in the ICU to be "very satisfactory" (93.8%, n = 411) with none of the survivors stating they were either "dissatisfied" or "very dissatisfied". In common with HIC, survivors were very satisfied with their ICU care. In contrast to HIC settings, specific ICU experiences were frequently not recalled, but those remembered were reported as relatively stress-free. Stressful experiences, in common with HIC, were most frequently related to uncertainty about the future, dependency, family, and economic concerns.

Cancer patients requiring mechanical ventilation are widely viewed as poor candidates for intensive care unit (ICU) admission. We designed a prospective study evaluating a new admission policy titled The ICU Trial. Prospective study. Intensive care unit. One hundred eighty-eight patients requiring mechanical ventilation and having at least one other organ failure. Over a 3-yr period, all patients with hematologic malignancies or solid tumors proposed for ICU admission underwent a triage procedure. Bedridden patients and patients in whom palliative care was the only cancer treatment option were not admitted to the ICU. Patients at earliest phase of the malignancy (diagnosis < 30 days) were admitted without any restriction. All other patients were prospectively included in The ICU Trial, consisting of a full-code ICU admission followed by reappraisal of the level of care on day 5. Among the 188 patients, 103 survived the first 4 ICU days and 85 died from the acute illness. Hospital survival was 21.8% overall. Among the 103 survivors on day 5, none of the characteristics of the malignancy were significantly different between the 62 patients who died and the 41 who survived. Time course of organ dysfunction over the first 6 ICU days differed significantly between survivors and nonsurvivors. Organ failure scores were more accurate on day 6 than at admission or on day 3 for predicting survival. All patients who required initiation of mechanical ventilation, vasopressors, or dialysis after 3 days in the ICU died. Survival was 40% in mechanically ventilated cancer patients who survived to day 5 and 21.8% overall. If these results are confirmed in future interventional studies, we recommend ICU admission with full-code management followed by reappraisal on day 6 in all nonbedridden cancer patients for whom lifespan-extending cancer treatment is available.

A prospective, 5-month observational and descriptive study was carried out. ICU of Marqués de Valdecilla University Hospital, Santander (Spain). Adult patients with an ICU stay longer than 24h, who were discharged to the ward during the period of the study, and their relatives. Instrument: FS-ICU 34 for assessing family satisfaction, and an adaptation of the FS-ICU 34 for patients. The Cohen kappa index was calculated to assess agreement between answers. An analysis was made of the questionnaires from one same family unit, obtaining 148 pairs of surveys (296 questionnaires). The kappa index ranged between 0.278-0.558, which is indicative of mild to moderate agreement. The families of patients admitted to the ICU cannot be regarded as good proxies, at least for competent patients. In such cases, we must refer to these patients in order to obtain first hand information on their feelings, perceptions and experiences during admission to the ICU. Only when patients are unable to actively participate in the care process should their relatives be consulted. Copyright © 2016 Elsevier España, S.L.U. y SEMICYUC. All rights reserved.

A path to precision in the ICU.

PubMed

Maslove, David M; Lamontagne, Francois; Marshall, John C; Heyland, Daren K

2017-04-03

Precision medicine is increasingly touted as a groundbreaking new paradigm in biomedicine. In the ICU, the complexity and ambiguity of critical illness syndromes have been identified as fundamental justifications for the adoption of a precision approach to research and practice. Inherently protean diseases states such as sepsis and acute respiratory distress syndrome have manifestations that are physiologically and anatomically diffuse, and that fluctuate over short periods of time. This leads to considerable heterogeneity among patients, and conditions in which a "one size fits all" approach to therapy can lead to widely divergent results. Current ICU therapy can thus be seen as imprecise, with the potential to realize substantial gains from the adoption of precision medicine approaches. A number of challenges still face the development and adoption of precision critical care, a transition that may occur incrementally rather than wholesale. This article describes a few concrete approaches to addressing these challenges.First, novel clinical trial designs, including registry randomized controlled trials and platform trials, suggest ways in which conventional trials can be adapted to better accommodate the physiologic heterogeneity of critical illness. Second, beyond the "omics" technologies already synonymous with precision medicine, the data-rich environment of the ICU can generate complex physiologic signatures that could fuel precision-minded research and practice. Third, the role of computing infrastructure and modern informatics methods will be central to the pursuit of precision medicine in the ICU, necessitating close collaboration with data scientists. As work toward precision critical care continues, small proof-of-concept studies may prove useful in highlighting the potential of this approach.

The aim of the study was to determine emotional reactions and needs of families of ICU patients. The study group included 60 relatives of ICU patients, aged 18-80 years. The diagnostic questionnaire-based survey was conducted. The questionnaire contained questions regarding demographic data, emotions and needs as well as the Courtauld Emotional Control Scale (CECS). The major emotions of patients' families on ICU admission were anxiety, uncertainty, fear, depression, and nervousness (particularly among parents and adult offsprings). On second-third day of hospitalisation, the emotions became less severe (P < 0.001). The anxiety-related emotional reactions were better controlled by men (P < 0.01); most women experienced stronger negative emotions (P < 0.05) and their needs to receive information and to be involved in patient care were expressed more. Negative emotions of ICU patients' relatives were highly intense, especially amongst parents and adult children. Women were characterised by higher levels of emotions and needs compared to men.

Background Intensive care unit (ICU) telemedicine is an increasingly common strategy for improving the outcome of critical care, but its overall impact is uncertain. Objectives To determine the effectiveness of ICU telemedicine in a national sample of hospitals and quantify variation in effectiveness across hospitals. Research design We performed a multi-center retrospective case-control study using 2001–2010 Medicare claims data linked to a national survey identifying United States hospitals adopting ICU telemedicine. We matched each adopting hospital (cases) to up to 3 non-adopting hospitals (controls) based on size, case-mix and geographic proximity during the year of adoption. Using ICU admissions from 2 years before and after the adoption date, we compared outcomes between case and control hospitals using a difference-in-differences approach. Results 132 adopting case hospitals were matched to 389 similar non-adopting control hospitals. The pre- and post-adoption unadjusted 90-day mortality was similar in both case hospitals (24.0% vs. 24.3%, p=0.07) and control hospitals (23.5% vs. 23.7%, p<0.01). In the difference-in-differences analysis, ICU telemedicine adoption was associated with a small relative reduction in 90-day mortality (ratio of odds ratios: 0.96, 95% CI = 0.95–0.98, p<0.001). However, there was wide variation in the ICU telemedicine effect across individual hospitals (median ratio of odds ratios: 1.01; interquartile range 0.85–1.12; range 0.45–2.54). Only 16 case hospitals (12.2%) experienced statistically significant mortality reductions post-adoption. Hospitals with a significant mortality reduction were more likely to have large annual admission volumes (p<0.001) and be located in urban areas (p=0.04) compared to other hospitals. Conclusions Although ICU telemedicine adoption resulted in a small relative overall mortality reduction, there was heterogeneity in effect across adopting hospitals, with large-volume urban hospitals

Children and terror casualties receive preference in ICU admissions.

Trauma casualties caused by terror-related events and children injured as a result of trauma may be given preference in hospital emergency departments (EDs) due to their perceived importance. We investigated whether there are differences in the treatment and hospitalization of terror-related casualties compared to other types of injury events and between children and adults injured in terror-related events. Retrospective study of 121 608 trauma patients from the Israel Trauma Registry during the period of October 2000-December 2005. Of the 10 hospitals included in the registry, 6 were level I trauma centers and 4 were regional trauma centers. Patients who were hospitalized or died in the ED or were transferred between hospitals were included in the registry. All analyses were controlled for Injury Severity Score (ISS). All patients with ISS 1-24 terror casualties had the highest frequency of intensive care unit (ICU) admissions when compared with patients after road traffic accidents (RTA) and other trauma. Among patients with terror-related casualties, children were admitted to ICU disproportionally to the severity of their injury. Logistic regression adjusted for injury severity and trauma type showed that both terror casualties and children have a higher probability of being admitted to the ICU. Injured children are admitted to ICU more often than other age groups. Also, terror-related casualties are more frequently admitted to the ICU compared to those from other types of injury events. These differences were not directly related to a higher proportion of severe injuries among the preferred groups.

International literature on end-of-life care in intensive care units (ICUs) supports the use of 'protocol bundles', which is not common practice in our 18-bed adult general ICU in Sydney, New South Wales. We conducted a prospective observational study to identify problems related to end-of-life care practices and to determine whether there was a need to develop protocol bundles. Any ICU patient who had 'withdrawal' of life-sustaining treatment to facilitate a comfortable death was eligible. Exclusion criteria included organ donors, unsuitable family dynamics and lack of availability of research staff to obtain family consent. Process-of-care measures were collected using a standardised form. Satisfaction ratings were obtained using de-identified questionnaire surveys given to the healthcare staff shortly after the withdrawal of therapy and to the families 30 days later. Twenty-three patients were enrolled between June 2011 and July 2012. Survey questionnaires were given to 25 family members and 30 healthcare staff, with a high completion rate (24 family members [96%] and 28 staff [93.3%]). Problems identified included poor documentation of family meetings (39%) and symptom management. Emotional/spiritual support was not offered to families (39.1%) or ICU staff (0%). The overall level of end-of-life care was good. The overwhelming majority of families and healthcare staff were highly satisfied with the care provided. Problems identified related to communication documentation and lack of spiritual/emotional support. To address these problems, targeted measures would be more useful than the adoption of protocol bundles. Alternate models of satisfaction surveys may be needed.

To determine European intensive care unit (ICU) nurses' knowledge of guidelines for preventing central venous catheter-related infection from the Centers for Disease Control and Prevention. Multicountry survey (October 2006-March 2007). Twenty-two European countries. ICU nurses. Using a validated multiple-choice test, knowledge of ten recommendations for central venous catheter-related infection prevention was evaluated (one point per question) and assessed in relation to participants' gender, ICU experience, number of ICU beds, and acquisition of a specialized ICU qualification. We collected 3405 questionnaires (70.9% response rate); mean test score was 44.4%. Fifty-six percent knew that central venous catheters should be replaced on indication only, and 74% knew this also concerns replacement over a guidewire. Replacing pressure transducers and tubing every 4 days, and using coated devices in patients requiring a central venous catheter >5 days in settings with high infection rates only were recognized as recommended by 53% and 31%, respectively. Central venous catheters dressings in general are known to be changed on indication and at least once weekly by 43%, and 26% recognized that both polyurethane and gauze dressings are recommended. Only 14% checked 2% aqueous chlorhexidine as the recommended disinfection solution; 30% knew antibiotic ointments are not recommended because they trigger resistance. Replacing administration sets within 24 hrs after administering lipid emulsions was recognized as recommended by 90%, but only 26% knew sets should be replaced every 96 hrs when administering neither lipid emulsions nor blood products. Professional seniority and number of ICU beds showed to be independently associated with better test scores. Opportunities exist to optimize knowledge of central venous catheter-related infection prevention among European ICU nurses. We recommend including central venous catheter-related infection prevention guidelines in educational

Many patients with diabetes and their care providers are unaware of the presence of the disease. Dysglycemia encompassing hyperglycemia, hypoglycemia, and glucose variability is common in the ICU in patients with and without diabetes. The purpose of this study was to determine the impact of unknown diabetes on glycemic control in the ICU. Prospective observational study. Nine ICUs in an academic, tertiary hospital and a hybrid academic/community hospital. Hemoglobin A1c levels were ordered at all ICU admissions from March 1, 2011 to September 30, 2013. Electronic medical records were examined for a history of antihyperglycemic medications or International Classification of Diseases, 9th Edition diagnosis of diabetes. Patients were categorized as having unknown diabetes (hemoglobin A1c > 6.5%, without history of diabetes), no diabetes (hemoglobin A1c < 6.5%, without history of diabetes), controlled known diabetes (hemoglobin A1c < 6.5%, with documented history of diabetes), and uncontrolled known diabetes (hemoglobin A1c > 6.5%, with documented history of diabetes). None. A total of 15,737 patients had an hemoglobin A1c and medical record evaluable for the history of diabetes, and 5,635 patients had diabetes diagnosed by either medical history or an elevated hemoglobin A1c in the ICU. Of these, 1,460 patients had unknown diabetes, accounting for 26.0% of all patients with diabetes. This represented 41.0% of patients with an hemoglobin A1c > 6.5% and 9.3% of all ICU patients. Compared with patients without diabetes, patients with unknown diabetes had a higher likelihood of requiring an insulin infusion (44.3% vs 29.3%; p < 0.0001), a higher average blood glucose (172 vs 126 mg/dL; p < 0.0001), an increased percentage of hyperglycemia (19.7% vs 7.0%; blood glucose > 180 mg/dL; p < 0.0001) and hypoglycemia (8.9% vs 2.5%; blood glucose < 70 mg/dL; p < 0.0001), higher glycemic variability (55.6 vs 28.8, average of patient SD of glucose; p < 0.0001), and increased

2018-06-01

To develop a valid, reliable measure that reflected the environment of respectfulness within the ICU setting. We developed a preliminary survey instrument based on conceptual domains of respect identified through prior qualitative analyses of ICU patient, family member, and clinician perspectives. The initial instrument consisted of 21 items. After five cognitive interviews and 16 pilot surveys, we revised the instrument to include 23 items. We used standard psychometric methods to analyze the instrument. Eight ICUs serving adult patients affiliated with a large university health system. ICU clinicians. None. Based on 249 responses, we identified three factors and created subscales: General Respect, Respectful Behaviors, and Disrespectful Behaviors. The General Respect subscale had seven items (α = 0.932) and reflected how often patients in the ICU are treated with respect, in a dignified manner, as an individual, equally to all other patients, on the "same level" as the ICU team, as a person, and as you yourself would want to be treated. The Respectful Behaviors subscale had 10 items (α = 0.926) and reflected how often the ICU team responds to patient and/or family anxiety, makes an effort to get to know the patient and family as people, listens carefully, explains things thoroughly, gives the opportunity to provide input into care, protects patient modesty, greets when entering room, and talks to sedated patients. The subscale measuring disrespect has four items (α = 0.702) and reflects how often the ICU team dismisses family concerns, talks down to patients and families, speaks disrespectfully behind their backs, and gets frustrated with patients and families. We created a reliable set of scales to measure the climate of respectfulness in intensive care settings. These measures can be used for ongoing quality improvement that aim to enhance the experience of ICU patients and their families.

Acquisition of ICU data: concepts and demands.

Imhoff, M

1992-12-01

As the issue of data overload is a problem in critical care today, it is of utmost importance to improve acquisition, storage, integration, and presentation of medical data, which appears only feasible with the help of bedside computers. The data originates from four major sources: (1) the bedside medical devices, (2) the local area network (LAN) of the ICU, (3) the hospital information system (HIS) and (4) manual input. All sources differ markedly in quality and quantity of data and in the demands of the interfaces between source of data and patient database. The demands for data acquisition from bedside medical devices, ICU-LAN and HIS concentrate on technical problems, such as computational power, storage capacity, real-time processing, interfacing with different devices and networks and the unmistakable assignment of data to the individual patient. The main problem of manual data acquisition is the definition and configuration of the user interface that must allow the inexperienced user to interact with the computer intuitively. Emphasis must be put on the construction of a pleasant, logical and easy-to-handle graphical user interface (GUI). Short response times will require high graphical processing capacity. Moreover, high computational resources are necessary in the future for additional interfacing devices such as speech recognition and 3D-GUI. Therefore, in an ICU environment the demands for computational power are enormous. These problems are complicated by the urgent need for friendly and easy-to-handle user interfaces. Both facts place ICU bedside computing at the vanguard of present and future workstation development leaving no room for solutions based on traditional concepts of personal computers.(ABSTRACT TRUNCATED AT 250 WORDS)

ICU telemedicine uses audiovisual conferencing technology to provide critical care from a remote location. Research is needed to best define the optimal use of ICU telemedicine, but efforts are hindered by methodological challenges and the lack of an organized delivery approach. We convened an interdisciplinary working group to develop a research agenda in ICU telemedicine, addressing both methodological and knowledge gaps in the field. To best inform clinical decision-making and health policy, future research should be organized around a conceptual framework that enables consistent descriptions of both the study setting and the telemedicine intervention. The framework should include standardized methods for assessing the preimplementation ICU environment and describing the telemedicine program. This framework will facilitate comparisons across studies and improve generalizability by permitting context-specific interpretation. Research based on this framework should consider the multidisciplinary nature of ICU care and describe the specific program goals. Key topic areas to be addressed include the effect of ICU telemedicine on the structure, process, and outcome of critical care delivery. Ideally, future research should attempt to address causation instead of simply associations and elucidate the mechanism of action in order to determine exactly how ICU telemedicine achieves its effects. ICU telemedicine has significant potential to improve critical care delivery, but high-quality research is needed to best inform its use. We propose an agenda to advance the science of ICU telemedicine and generate research with the greatest potential to improve patient care.

To review the legal issues concerning family members' access to information when patients are in the ICU. U.S. Code, U.S. Code of Federal Regulations, and state legislative codes. Relevant legal statutes and regulations were identified and reviewed by the two attorney authors (L. F., M. A. V.). Not applicable. Review by all coauthors. The Health Insurance Portability and Accountability Act and related laws should not be viewed as barriers to clinicians sharing information with ICU patients and their loved ones. Generally, under Health Insurance Portability and Accountability Act, personal representatives have the same authority to receive information that patients would otherwise have. Persons involved in the patient's care also may be given information relevant to the episode of care unless the patient objects. ICUs should develop policies for handling the issues we identify about such information sharing, including policies for responding to telephone inquiries and methods for giving patients the opportunity to object to sharing information with individuals involved in their care. ICU clinicians also should be knowledgeable of their state's laws about how to identify patients' personal representatives and the authority of those representatives. Finally, ICU clinicians should be aware of any special restrictions their state places on medical information. In aggregate, these strategies should help ICU managers and clinicians facilitate robust communication with patients and their loved ones.

The patient burden in intensive care units (ICU) has continually increased worldwide over the past decades. Age, co-morbidities and an increasing complexity of conditions and treatments increase the number of patients who are either colonized or infected with antibiotic-resistant pathogens. To prevent nosocomial infections, hygiene guidelines play an important role. In this paper, we investigate the time needed for nursing of five hypothetical critically ill patients in the intensive care unit. The results show that current staffing is not sufficient under the given hygiene guidelines and that a nurse to patient ratio of one will be necessary to meet the requirements. In a national survey of university hospitals, however, we found that the current nurse to patient ratio is 1: 2.47 in German intensive care units. The apparent staffing shortage is compensated by an extraordinary personal commitment of nurses caring for patients in the ICU. © Georg Thieme Verlag KG Stuttgart · New York.

Pain and fear are still the most common memories that refer patients after ICU admission. Recently an important politician named the UCI as the branch of the hell. It is necessary to carry out profound changes in terms of direct relationships with patients and their relatives, as well as changes in environmental design and work and visit organization, to banish the vision that our society about the UCI. In a step which advocates for early mobilization of critical patients is necessary to improve analgesia and sedation strategies. The ICU is the best place for administering and monitoring analgesic drugs. The correct analgesia should not be a pending matter of the intensivist but a mandatory course.

Mechanisms underlying ICU muscle wasting and effects of passive mechanical loading

PubMed Central

2012-01-01

Introduction Critically ill ICU patients commonly develop severe muscle wasting and impaired muscle function, leading to delayed recovery, with subsequent increased morbidity and financial costs, and decreased quality of life for survivors. Critical illness myopathy (CIM) is a frequently observed neuromuscular disorder in ICU patients. Sepsis, systemic corticosteroid hormone treatment and post-synaptic neuromuscular blockade have been forwarded as the dominating triggering factors. Recent experimental results from our group using a unique experimental rat ICU model show that the mechanical silencing associated with CIM is the primary triggering factor. This study aims to unravel the mechanisms underlying CIM, and to evaluate the effects of a specific intervention aiming at reducing mechanical silencing in sedated and mechanically ventilated ICU patients. Methods Muscle gene/protein expression, post-translational modifications (PTMs), muscle membrane excitability, muscle mass measurements, and contractile properties at the single muscle fiber level were explored in seven deeply sedated and mechanically ventilated ICU patients (not exposed to systemic corticosteroid hormone treatment, post-synaptic neuromuscular blockade or sepsis) subjected to unilateral passive mechanical loading for 10 hours per day (2.5 hours, four times) for 9 ± 1 days. Results These patients developed a phenotype considered pathognomonic of CIM; that is, severe muscle wasting and a preferential myosin loss (P < 0.001). In addition, myosin PTMs specific to the ICU condition were observed in parallel with an increased sarcolemmal expression and cytoplasmic translocation of neuronal nitric oxide synthase. Passive mechanical loading for 9 ± 1 days resulted in a 35% higher specific force (P < 0.001) compared with the unloaded leg, although it was not sufficient to prevent the loss of muscle mass. Conclusion Mechanical silencing is suggested to be a primary mechanism underlying CIM; that is

Understanding ICU workflow and how it is impacted by ICU strain is necessary for implementing effective improvements. This study aimed to quantify how ICU physicians spend time and to examine the impact of ICU strain on workflow. Prospective, observational time-motion study. Five ICUs in two hospitals at an academic medical center. Thirty attending and resident physicians. None. In 137 hours of field observations, the most time-84 hours (62% of total observation time)-was spent on professional communication. Reviewing patient data and documentation occupied a combined 52 hours (38%), whereas direct patient care and education occupied 24 hours (17%) and 13 hours (9%), respectively. The most frequently used tool was the computer, used in tasks that occupied 51 hours (37%). Severity of illness of the ICU on day of observation was the only strain factor that significantly impacted work patterns. In a linear regression model, increase in average ICU Sequential Organ Failure Assessment was associated with more time spent on direct patient care (β = 4.3; 95% CI, 0.9-7.7) and education (β = 3.2; 95% CI, 0.7-5.8), and less time spent on documentation (β = -7.4; 95% CI, -11.6 to -3.2) and on tasks using the computer (β = -7.8; 95% CI, -14.1 to -1.6). These results were more pronounced with a combined strain score that took into account unit census and Sequential Organ Failure Assessment score. After accounting for ICU type (medical vs surgical) and staffing structure (resident staffed vs physician assistant staffed), results changed minimally. Clinicians spend the bulk of their time in the ICU on professional communication and tasks involving computers. With the strain of high severity of illness and a full unit, clinicians reallocate time from documentation to patient care and education. Further efforts are needed to examine system-related aspects of care to understand the impact of workflow and strain on patient care.

Sepsis is a leading cause of mortality and critical illness worldwide and is associated with an increased mortality rate in the months following hospital discharge. The occurrence of persistent or new organ dysfunction(s) after septic shock raises questions about the mechanisms involved in the post-sepsis status. The present study aimed to explore the immune profiles of patients one year after being discharged from the intensive care unit (ICU) following treatment for abdominal septic shock. We conducted a prospective, single-center, observational study in the surgical ICU of a university hospital. Eighty-six consecutive patients admitted for septic shock of abdominal origin were included in this study. Fifteen different plasma biomarkers were measured at ICU admission, at ICU discharge and at one year after ICU discharge. Three different clusters of biomarkers were distinguished according to their functions, namely: (1) inflammatory response, (2) cell damage and apoptosis, (3) immunosuppression and resolution of inflammation. The primary objective was to characterize variations in the immune status of septic shock patients admitted to ICU up to one year after ICU discharge. The secondary objective was to evaluate the relationship between these biomarker variations and patient outcomes. At the onset of septic shock, we observed a cohesive pro-inflammatory profile and low levels of inflammation resolution markers. At ICU discharge, the immune status demonstrated decreased but persistent inflammation and increased immunosuppression, with elevated programmed cell death protein-1 (PD-1) levels, and a counterbalanced resolution process, with elevated levels of interleukin-10 (IL-10), resolvin D5 (RvD5), and IL-7. One year after hospital discharge, homeostasis was not completely restored with several markers of inflammation remaining elevated. Remarkably, IL-7 was persistently elevated, with levels comparable to those observed after ICU discharge, and PD-1, while lower

Intensive care medicine (ICM) is increasingly utilized by a growing number of critically ill patients worldwide. The reasons for this are an increasingly ageing and multimorbid population and technological improvements in ICM. Inappropriate patient admissions to the intensive care unit (ICU) can be a threat to rational resource allocation and to patient autonomy. In this study, the incidence, characteristics, and resource utilization of patients inappropriately admitted to ICUs are studied. This prospective study included all consecutive patients admitted from 01 September 2012 to 31 August 2013 to the Department of Intensive Care Medicine of a German university hospital comprised of 10 ICUs and 120 beds. Inappropriate admission was defined according to category 4B of the recommendations of the Society of Critical Care Medicine (SCCM; "futility of ICU treatment" or "ICU declined by patient") and was determined in each suspected case by structured group discussions between the study team and all involved care givers including the referring team. In all, 66 of 6452 ICU admissions (1 %) were suspected to have been inappropriate on retrospective evaluation the day after admission. In 50 patients (0.8 %), an interdisciplinary consensus was reached on the inappropriateness of the ICU admission. Of these 50 patients, 41 (82 %) had previously declined ICU treatment in principle. This information was based on the patient's presumed wish as expressed by next of kin (56 %) or in a written advanced directive (26 %). In 9 patients (18 %), ICU treatment was considered futile. In all cases, a lack of information regarding a patient's wishes or clinical prognosis was the reason for inappropriate ICU admission. In this study, patients were regularly admitted to the ICU despite their contrary wish/directive or an unfavorable clinical condition. Although this was registered in only 1 % of all admissions, optimizing preICU admission information flow with regard to

Observational cohort study in which computerized billing and medical records were screened over a 2-year period. Six specialty ICUs across two hospitals in an academic health system. Eligible patients were awake, alert, and responsive to verbal communication from clinicians for at least one 12-h nursing shift while receiving MV ≥ 2 consecutive days. Of the 2671 MV patients screened, 1440 (53.9%) met basic communication criteria. The Neurological ICU had the lowest proportion of MV patients meeting communication criteria (40.82%); Trauma ICU had the highest proportion (69.97%). MV patients who did not meet basic communication criteria (n = 1231) were younger, had shorter lengths of stay and lower costs, and were more likely to die during the hospitalization. We estimate that half of MV patients in the ICU could potentially be served by assistive communication tools and speech-language consultation. Copyright © 2015 Elsevier Inc. All rights reserved.

Family members of intensive care unit (ICU) patients are at risk for symptoms of post-traumatic stress disorder (PTSD) following ICU discharge. The aim of this systematic review is to examine the current literature regarding post-ICU family PTSD symptoms with an emphasis on methodological issues in conducting research on this challenging phenomenon. An extensive review of the literature was performed confining the search to English language studies reporting PTSD symptoms in adult family members of adult ICU patients. Ten studies were identified for review published from 2004–2012. Findings demonstrate a significant prevalence of family PTSD symptoms in the months following ICU hospitalization. However, there are several methodological challenges to the interpretation of existing studies and to the conduct of future research including differences in sampling, identification of risk factors and covariates of PTSD, and lack of consensus regarding the most appropriate PTSD symptom measurement tools and timing.

Ventilator-associated pneumonia (VAP) is the most common intensive care unit (ICU)-acquired infection among patients requiring mechanical ventilation. A prospective surveillance programme of all patients has been implemented at the ICU, Karolinska University Hospital, Sweden since 2001. Within this programme, incidence and risk factors for ICU-acquired pneumonia and associated death over a 2-y period have been studied. Of 329 patients enrolled in the study, 221 required mechanical ventilation. 33 of 221 patients (15%) developed VAP, corresponding to a rate of 29 VAP/1000 ventilator d. Risk factors for VAP were aspiration (hazard ratio 3.79; 95% CI 1.48-9.68), recent surgery (HR 3.58; 95% CI 1.15-11.10) and trauma (HR 3.00; 95% CI 1.03-8.71). 11 patients of 33 (33%) with VAP died within 28 d compared to 46 of 288 (16%) without ICU-acquired pneumonia (odds ratio 2.73; 95% CI 0.97-7.63). We conclude that: 1) incidence of VAP was 15% and the most important risk factor was aspiration; 2) APACHE II score > or = 20 is a stronger predictor for poor outcome than VAP; 3) a minority of patients with APACHE II score > or = 20 develop VAP; and 4) continuous surveillance programmes are feasible and provide valuable data for improvement of quality of care.

ICU needs of nontrauma emergency general surgery patients are poorly described. This study was designed to compare ICU utilization of emergency general surgery patients admitted to an acute care emergency surgery service with other general surgery patients. Our hypothesis is that tertiary care emergency general surgery patients utilize more ICU resources than other general surgical patients. Retrospective database review. Academic, tertiary care, nontrauma surgical ICU. All patients admitted to the surgical ICU over age 18 between March 2004 and June 2012. None. Six thousand ninety-eight patients were evaluated: 1,053 acute care emergency surgery, 1,964 general surgery, 1,491 transplant surgery, 995 facial surgery/otolaryngology, and 595 neurosurgery. Acute care emergency surgery patients had statistically significantly longer ICU lengths of stay than other groups: acute care emergency surgery (13.5 ± 17.4 d) versus general surgery (8.7 ± 12.9), transplant (7.8 ± 11.6), oral-maxillofacial surgery (5.5 ± 4.2), and neurosurgery (4.47 ± 9.8) (all p< 0.01). Ventilator usage, defined by percentage of total ICU days patients required mechanical ventilation, was significantly higher for acute care emergency surgery patients: acute care emergency surgery 73.4% versus general surgery 64.9%, transplant 63.3%, oral-maxillofacial surgery 58.4%, and neurosurgery 53.1% (all p < 0.01). Continuous renal replacement therapy usage, defined as percent of patients requiring this service, was significantly higher in acute care emergency surgery patients: acute care emergency surgery 10.8% versus general surgery 4.3%, transplant 6.6%, oral-maxillofacial surgery 0%, and neurosurgery 0.5% (all p < 0.01). Acute care emergency surgery patients were more likely interhospital transfers for tertiary care services than general surgery or transplant (24.5% vs 15.5% and 8.3% respectively, p < 0.001 for each) and more likely required emergent surgery (13.7% vs 6.7% and 3.5%, all p < 0

The application of tracheal cuff pressure monitoring is likely to vary between institutions. The aim of this study was therefore to review current evidence concerning this intervention in the intensive care unit (ICU) and to appraise regional practice by performing a state-wide survey. Publications for review were identified through searches of PubMed, EMBASE and Cochrane (1977 to 2014). All studies in English relevant to critical care and with complete data were included. Survey questions were developed by small-group consensus. Public and private ICUs across Queensland were contacted, with responses obtained from a representative member of the medical or nursing staff. Existing literature suggests significant variability in tracheal cuff pressure monitoring in the ICU, particularly in the applied technique, frequency of assessment and optimal intra-cuff pressures. Twenty-nine respondents completed the survey, representing 80.5% (29/36) of ICUs in Queensland. Twenty-eight out of twenty-nine respondents reported routinely monitoring tracheal cuff function, primarily employing cuff pressure measurement (26/28). Target cuff pressures varied, with 3/26 respondents aiming for 10 to 20 cmH2O, 10/26 for 21 to 25 cmH2O, and 13/26 for 26 to 30 cmH2O. Fifteen out of twenty-nine reported they had no current guideline or protocol for tracheal cuff management and only 16/29 indicated there was a dedicated area in the clinical record for reporting cuff intervention. Our results indicate that many ICUs across Queensland routinely measure tracheal cuff function, with most utilising pressure monitoring devices. Consistent with existing literature, the optimum cuff pressure remains uncertain. Most, however, considered that this should be a routine part of ICU care.

The purpose was 1) to prospectively determine the prevalence of adverse events necessitating intensive care unit (ICU) monitoring in gallstone pancreatitis (GP) and 2) To identify admission prognostic indicators that predict the need for ICU unit monitoring. Prospective laboratory data, physiologic parameters, and APACHE II scores were gathered on 102 patients with GP over 14 months. Adverse events were defined as cardiac, respiratory, or renal failure, gastrointestinal bleeding, stroke, sepsis, and necrotizing pancreatitis. Patients were divided into Group 1 (no adverse events, n=95) and Group 2 (adverse events, n=7). There were no deaths and 7 (7%) adverse events, including necrotizing pancreatitis (3), cholangitis (2), and cardiac (2). APACHE 11 > or = 5 (P < 0.005), blood urea nitrogen (BUN) > or = 12 mmol/L (P < 0.005), white blood cell count (WBC) > or = 14.5 x 10(9)/L, (P < 0.001), heart rate > or = 100 bpm (P < 0.001), and glucose > or = 150 mg/dL (P < 0.005) were each independent predictors of adverse events. The sensitivity and specificity of these criteria for predicting severe complications requiring ICU care varied from 71 to 86 per cent and 78 to 87 per cent, respectively. The prevalence of adverse events necessitating ICU care in GP patients is low. Glucose, BUN, WBC, heart rate, and APACHE II scores are independent predictors of adverse events necessitating ICU care. Single criteria predicting the need for ICU care on admission are readily available on admission.

The nursing role in ICU outreach: an international exploratory study.

It is widely acknowledged that many critically ill patients are managed outside of designated critical care units. One strategy adopted in Australia and England to assess and manage risk in these patients is the intensive care unit (ICU) outreach or liaison nurse service. This article examines how ICU outreach/liaison roles in Australia and England operate in the context of Manley's theoretical framework for advanced nursing practice. Descriptive case study design using semi-structured interviews and job descriptions as sources of evidence. Findings of interviews with six Australian ICU Liaison nurses are already published; this study replicated the Australian study with four ICU Consultant Nurses in England and mapped interview and job description data from both countries onto Manley's conceptual framework for advanced practice/consultant nurse. Four themes emerged from the English data: patient interventions, support for ward staff, liaison between ward and ICU staff and hospital-wide impact. The first three of these comprised the core service common to the roles in both countries. Manley's four subroles (expert practitioner, consultant, educator and researcher) were present across both countries. However, the interview and job description data demonstrated that there were lower expectations in Australia that the roles would lead to staff development and build capacity across the hospital system. Similarly, formal education for ward staff such as ALERT and CRiSP courses were more developed in UK. Our data demonstrate that the role undertaken in England and Australia is sufficiently comparable to use as a research intervention in international studies across the two countries. However, the macro service level differs. Job descriptions across both countries emphasized the need to influence hospital policy; however, the ICU consultant nurses in England might be considered better placed to achieve this through role title and access to the hospital executive.

Although a growing body of evidence has associated the ICU family meeting with important, favorable outcomes for critically ill patients, their families, and health care systems, these meetings often fail to occur in a timely, effective, and reliable way. In this article, we describe three specific tools that we have developed as prototypes to promote more successful implementation of family meetings in the ICU: 1) A Family Meeting Planner; 2) A Meeting Guide for Families; and 3) A Family Meeting Documentation Template. We describe the essential features of these tools and ways that they might be adapted to meet the local needs of individual ICUs and to maximize acceptability and use. We also discuss the role of such tools in structuring a performance improvement initiative. Just as simple tools have helped to reduce bloodstream infections, our hope is that the toolkit presented here will help critical care teams to meet the important communication needs of ICU families.

The purpose of the study was to examine how tele-intensive care unit (tele-ICU) nurse characteristics and organizational characteristics influence tele-ICU nurses' trust and satisfaction of monitored bedside ICU nurses, and whether these influences are mediated by communication. Data of tele-ICU characteristics and characteristics of the ICUs they monitored were collected at 5 tele-ICUs located throughout the country. One hundred ten tele-ICU nurses at those tele-ICUs completed a questionnaire containing items related to their characteristics and their trust, satisfaction, and perceived communication with monitored bedside nurses. We analyzed the data using a hierarchical path model, with communication variables entered as mediators. Many of the tele-ICU nurse characteristics (age, currently or previously worked at the monitored ICU, hours worked per week, and years as a ICU nurse) had statistically significant direct effects on perception of communication timeliness, accuracy, and openness, as well as trust and satisfaction with monitored bedside ICU nurses. Communication openness mediated the relationships of both working at a monitored ICU and being older (≥55) on satisfaction. Communication accuracy mediated the relationships of both a specialized monitored ICU and working at a monitored ICU on trust. Tele-ICUs and monitored ICUs should work to optimize communication so that trust can be established among the nurses. Copyright © 2016 Elsevier Inc. All rights reserved.

Sleep in the pediatric ICU: an empirical investigation.

Although sleep is important for physical and psychological health, no research has assessed the sleep of children in a pediatric ICU and the factors that affect sleep. To observe the sleep of children in a pediatric ICU and to determine the relationship of noise, light, contact with caregivers, parental presence, and severity of illness to the sleep obtained by children in a pediatric ICU during a 10-hour night. At 5-minute intervals from 8 PM until 6 AM, a convenience sample of nine patients was observed. Sleep state, noise and light levels, contact with caregivers, and parental presence were recorded. Severity of illness was measured on admission and within 26 hours of data collection. Subjects slept for a mean total of 4.7 hours (SD = 0.49) during the 10-hour night, interrupted by a mean of 9.8 awakenings (SD = 2.48). The mean length of a sleep episode was only 27.6 minutes (SD = 25.85). Mean noise level was 55.1 dB(A) (SD = 6.82), with sudden, sharp elevations of up to 90 dB(A). Probit analysis indicated that noise, light, and contact with caregivers were significant predictors of sleep. Parental presence and severity of illness were not. Patients in the pediatric ICU sleep significantly less than is normal for children of the same ages, and their patterns of sleep are seriously disturbed. Because noise, light, and contact with caregivers are significant predictors of sleep state, health professionals can use these findings to structure the environment and the care they give to promote the sleep of critically ill children.

A Generic Simulation Model of the Relative Cost-Effectiveness of ICU Versus Step-Down (IMCU) Expansion.

Mahmoudian-Dehkordi, Amin; Sadat, Somayeh

2017-01-01

Many jurisdictions are facing increased demand for intensive care. There are two long-term investment options: intensive care unit (ICU) versus step-down or intermediate care unit (IMCU) capacity expansion. Relative cost-effectiveness of the two investment strategies with regard to patient lives saved has not been studied to date. We expand a generic system dynamics simulation model of emergency patient flow in a typical hospital, populated with empirical evidence found in the medical and hospital administration literature, to estimate the long-term effects of expanding ICU versus IMCU beds on patient lives saved under a common assumption of 2.1% annual increase in hospital arrivals. Two alternative policies of expanding ICU by two beds versus introducing a two-bed IMCU are compared over a ten-year simulation period. Russel equation is used to calculate total cost of patients' hospitalization. Using two possible values for the ratio of ICU to IMCU cost per inpatient day and four possible values for the percentage of patients transferred from ICU to IMCU found in the literature, nine scenarios are compared against the baseline scenario of no capacity expansion. Expanding ICU capacity by two beds is demonstrated as the most cost-effective scenario with an incremental cost-effectiveness ratio of 3684 (US $) per life saved against the baseline scenario. Sensitivity analyses on the mortality rate of patients in IMCU, direct transfer of IMCU-destined patients to the ward upon completing required IMCU length of stay in the ICU, admission of IMCU patient to ICU, adding two ward beds, and changes in hospital size do not change the superiority of ICU expansion over other scenarios. In terms of operational costs, ICU beds are more cost effective for saving patients than IMCU beds. However, capital costs of setting up ICU versus IMCU beds should be considered for a complete economic analysis.

Genome-wide association studies are now practical, and the first of these studies are appearing in the literature. This article provides the reader with an overview of the issues in technology and study design relating to genome-wide association studies and summarizes the current state of association studies in neonatal ICU populations with a brief review of the relevant literature. Future recommendations for genomic association studies in neonatal ICU populations are also provided.

Involvement of ICU families in decisions: fine-tuning the partnership

PubMed Central

2014-01-01

Families of patients are not simple visitors to the ICU. They have just been separated from a loved one, often someone they live with, either abruptly or, in nearly half the cases, because a chronic condition has suddenly worsened. They must cope with a serious illness of a loved one, while having to adapt to the unfamiliar and intimidating ICU environment. In many cases, the outcome of the critical illness is uncertain, a situation that causes considerable distress to the relatives. As shown by our research group and others, families exhibit symptoms of anxiety (70%) and depression (35%) in the first few days after admission, as well as symptoms of stress (33%) and difficulty understanding the information delivered by the healthcare staff (50%). Furthermore, relatives of patients who die in the ICU are at risk for psychiatric syndromes such as generalized anxiety, panic attacks, depression, and posttraumatic stress syndrome. In this setting of psychological distress, families are asked to consider sharing in healthcare decisions about their loved one in the ICU. This article aims to foster the debate about the shared decision-making process. We have three objectives: to transcend the overly simplistic position that opposes paternalism and autonomy, to build a view founded only on an evaluation of actual practice and experience in the field, and to keep the focus squarely on the patient. Families want information and communication time from the staff. Nurses and physicians need to understand that families can share in decisions only if the entire ICU staff actively promotes family involvement and, of course, if the family wants to participate in all or part of the decision-making process.

Winning the war against ICU-acquired weakness: new innovations in nutrition and exercise physiology.

Over the last 10 years we have significantly reduced hospital mortality from sepsis and critical illness. However, the evidence reveals that over the same period we have tripled the number of patients being sent to rehabilitation settings. Further, given that as many as half of the deaths in the first year following ICU admission occur post ICU discharge, it is unclear how many of these patients ever returned home. For those who do survive, the latest data indicate that 50-70% of ICU "survivors" will suffer cognitive impairment and 60-80% of "survivors" will suffer functional impairment or ICU-acquired weakness (ICU-AW). These observations demand that we as intensive care providers ask the following questions: "Are we creating survivors ... or are we creating victims?" and "Do we accomplish 'Pyrrhic Victories' in the ICU?" Interventions to address ICU-AW must have a renewed focus on optimal nutrition, anabolic/anticatabolic strategies, and in the future employ the personalized muscle and exercise evaluation techniques utilized by elite athletes to optimize performance. Specifically, strategies must include optimal protein delivery (1.2-2.0 g/kg/day), as an athlete would routinely employ. However, as is clear in elite sports performance, optimal nutrition is fundamental but alone is often not enough. We know burn patients can remain catabolic for 2 years post burn; thus, anticatabolic agents (i.e., beta-blockers) and anabolic agents (i.e., oxandrolone) will probably also be essential. In the near future, evaluation techniques such as assessing lean body mass at the bedside using ultrasound to determine nutritional status and ultrasound-measured muscle glycogen as a marker of muscle injury and recovery could be utilized to help find the transition from the acute phase of critical illness to the recovery phase. Finally, exercise physiology testing that evaluates muscle substrate utilization during exercise can be used to diagnose muscle mitochondrial dysfunction and

Telemedicine has been utilized in various healthcare areas to achieve better patient outcomes, lower costs of providing services, and increase patient access to care. Tele-intensive care unit (ICU) technology has been introduced as a way to provide effective ICU services to patients with reduced access, as well as to decrease costs and improve patient care. The methodology for this qualitative study was a literature search and review of case studies. The search was limited to sources published in the last 10 years (2003-2013) in the English language. In total, 55 references were used for this research exploration inquiry. Tele-ICU was found to be an effective way to use technology to decrease costs of providing intensive care, while improving patient outcomes such as mortality and length of stay. Several case studies supported the use of telemedicine in ICUs to provide intensive care to patients who lived in rural areas and lacked access to traditional ICUs. Furthermore, it was noted that, although the initial costs for tele-ICU startup were significant, as much as $100,000 per bed, the benefits of the utilization of this technology can offset those costs by reducing costs by 24% via decreased length of stay for patients. The findings of this study have suggested that the implementation of tele-ICU may have been more beneficial than costly, and it may have provided healthcare organizations the opportunity to increase quality of care and decrease mortality, while it might have decreased costs of delivering ICU services in both rural and urban areas.

The intensive care unit (ICU), where death is common and even survivors of an ICU stay face the risk of long-term morbidity and re-admissions to the ICU, represents an important setting for improving communication about palliative and end-of-life care. Communication about the goals of care in this setting should be a high priority since studies suggest that the current quality of ICU communication is often poor and is associated with psychological distress among family members of critically ill patients. This paper describes the development and evaluation of an intervention designed to improve the quality of care in the ICU by improving communication among the ICU team and with family members of critically ill patients. We developed a multi-faceted, interprofessional intervention based on self-efficacy theory. The intervention involves a "communication facilitator" - a nurse or social worker - trained to facilitate communication among the interprofessional ICU team and with the critically ill patient's family. The facilitators are trained using three specific content areas: a) evidence-based approaches to improving clinician-family communication in the ICU, b) attachment theory allowing clinicians to adapt communication to meet individual family member's communication needs, and c) mediation to facilitate identification and resolution of conflict including clinician-family, clinician-clinician, and intra-family conflict. The outcomes assessed in this randomized trial focus on psychological distress among family members including anxiety, depression, and post-traumatic stress disorder at 3 and 6 months after the ICU stay. This manuscript also reports some of the lessons that we have learned early in this study. Copyright © 2012 Elsevier Inc. All rights reserved.

Clostridium difficile in the ICU: the struggle continues.

PubMed

Bobo, Linda D; Dubberke, Erik R; Kollef, Marin

2011-12-01

Clostridium difficile infection (CDI) management has become more daunting over the past decade because of alarming increases in CDI incidence and severity both in the hospital and in the community. This increase has concomitantly caused significant escalation of the health-care economic burden caused by CDI, and it will likely be translated to increased ICU admission and attributable mortality. Some possible causes for difficulty in management of CDI are as follows: (1) inability to predict and prevent development of severe/complicated or relapsing CDI in patients who initially present with mild symptoms; (2) lack of a method to determine who would have benefited a priori from initiating vancomycin treatment first instead of treatment with metronidazole; (3) lack of sensitive and specific CDI diagnostics; (4) changing epidemiology of CDI, including the emergence of a hypervirulent, epidemic C difficile strain associated with increased morbidity and mortality; (5) association of certain high-usage nonantimicrobial medications with CDI; and (6) lack of treatment regimens that leave the normal intestinal flora undisturbed while treating the primary infection. The objective of this article is to present current management and prevention guidelines for CDI based on recommendations by the Society for Healthcare Epidemiology of America and Infectious Diseases Society of America and potential new clinical management strategies on the horizon.

The rapid introduction of Internet of Things (IoT) Technology has boosted the service deliverance aspects of health sector in terms of m-health, and remote patient monitoring. IoT Technology is not only capable of sensing the acute details of sensitive events from wider perspectives, but it also provides a means to deliver services in time sensitive and efficient manner. Henceforth, IoT Technology has been efficiently adopted in different fields of the healthcare domain. In this paper, a framework for IoT based patient monitoring in Intensive Care Unit (ICU) is presented to enhance the deliverance of curative services. Though ICUs remained a center of attraction for high quality care among researchers, still number of studies have depicted the vulnerability to a patient's life during ICU stay. The work presented in this study addresses such concerns in terms of efficient monitoring of various events (and anomalies) with temporal associations, followed by time sensitive alert generation procedure. In order to validate the system, it was deployed in 3 ICU room facilities for 30 days in which nearly 81 patients were monitored during their ICU stay. The results obtained after implementation depicts that IoT equipped ICUs are more efficient in monitoring sensitive events as compared to manual monitoring and traditional Tele-ICU monitoring. Moreover, the adopted methodology for alert generation with information presentation further enhances the utility of the system.

To develop and validate a noninvasive mobility sensor to automatically and continuously detect and measure patient mobility in the ICU. Prospective, observational study. Surgical ICU at an academic hospital. Three hundred sixty-two hours of sensor color and depth image data were recorded and curated into 109 segments, each containing 1,000 images, from eight patients. None. Three Microsoft Kinect sensors (Microsoft, Beijing, China) were deployed in one ICU room to collect continuous patient mobility data. We developed software that automatically analyzes the sensor data to measure mobility and assign the highest level within a time period. To characterize the highest mobility level, a validated 11-point mobility scale was collapsed into four categories: nothing in bed, in-bed activity, out-of-bed activity, and walking. Of the 109 sensor segments, the noninvasive mobility sensor was developed using 26 of these from three ICU patients and validated on 83 remaining segments from five different patients. Three physicians annotated each segment for the highest mobility level. The weighted Kappa (κ) statistic for agreement between automated noninvasive mobility sensor output versus manual physician annotation was 0.86 (95% CI, 0.72-1.00). Disagreement primarily occurred in the "nothing in bed" versus "in-bed activity" categories because "the sensor assessed movement continuously," which was significantly more sensitive to motion than physician annotations using a discrete manual scale. Noninvasive mobility sensor is a novel and feasible method for automating evaluation of ICU patient mobility.

Adverse events are unintended patient injuries or complications that arise from healthcare management resulting in death, disability or prolonged hospital stay. Adverse events that require critical care are a considerable financial burden to the healthcare system. Medical record review seems to be a reliable method for detecting adverse events. To synthesize the best available evidence regarding the estimates of the incidence and preventability of adverse events that necessitate intensive care admission; to determine the type and consequences (patient harm, mortality, length of ICU stay and direct medical costs) of these adverse events. MEDLINE (from 1966 to present), EMBASE (from 1974 to present) and CENTRAL (version 1-2010) were searched for studies reporting on unplanned admissions to intensive care units (ICUs). Databases of reports, conference proceedings, grey literature, ongoing research, relevant patient safety organizations and two journals were searched for additional studies. Reference lists of retrieved papers were searched and authors were contacted in an attempt to find any further published or unpublished work. Only quantitative studies that used chart review for the detection of adverse events requiring intensive care admission were considered for eligibility. Studies that were published in the English, Dutch, German, French or Spanish language were included. Two reviewers independently extracted data and assessed the methodological quality of the included studies. 28 studies in the English language and one study in French were included. Of these, two were considered duplicate publications and therefore 27 studies were reviewed. Meta-analysis of the data was not appropriate due to statistical heterogeneity between studies; therefore, results are presented in a descriptive way. Studies were categorized according to the population and the providers of care. 1) The majority of the included studies investigated unplanned intensive care admissions after

To evaluate the effect of an extended visitation model compared with a restricted visitation model on the occurrence of delirium among ICU patients. Prospective single-center before and after study. Thirty-one-bed medical-surgical ICU. All patients greater than or equal to 18 years old with expected length of stay greater than or equal to 24 hours consecutively admitted to the ICU from May 2015 to November 2015. Change of visitation policy from a restricted visitation model (4.5 hr/d) to an extended visitation model (12 hr/d). Two hundred eighty-six patients were enrolled (141 restricted visitation model, 145 extended visitation model). The primary outcome was the cumulative incidence of delirium, assessed bid using the confusion assessment method for the ICU. Predefined secondary outcomes included duration of delirium/coma; any ICU-acquired infection; ICU-acquired bloodstream infection, pneumonia, and urinary tract infection; all-cause ICU mortality; and length of ICU stay. The median duration of visits increased from 133 minutes (interquartile range, 97.7-162.0) in restricted visitation model to 245 minutes (interquartile range, 175.0-272.0) in extended visitation model (p < 0.001). Fourteen patients (9.6%) developed delirium in extended visitation model compared with 29 (20.5%) in restricted visitation model (adjusted relative risk, 0.50; 95% CI, 0.26-0.95). In comparison with restricted visitation model patients, extended visitation model patients had shorter length of delirium/coma (1.5 d [interquartile range, 1.0-3.0] vs 3.0 d [interquartile range, 2.5-5.0]; p = 0.03) and ICU stay (3.0 d [interquartile range, 2.0-4.0] vs 4.0 d [interquartile range, 2.0-6.0]; p = 0.04). The rate of ICU-acquired infections and all-cause ICU mortality did not differ significantly between the two study groups. In this medical-surgical ICU, an extended visitation model was associated with reduced occurrence of delirium and shorter length of delirium/coma and ICU stay.

We have significantly improved hospital mortality from sepsis and critical illness in last 10 years; however, over this same period we have tripled the number of 'ICU survivors' going to rehabilitation. Furthermore, as up to half the deaths in the first year following ICU admission occur post-ICU discharge, it is unclear how many of these patients ever returned home or a meaningful quality of life. For those who do survive, recent data reveals many 'ICU survivors' will suffer significant functional impairment or post-ICU syndrome (PICS). Thus, new innovative metabolic and exercise interventions to address PICS are urgently needed. These should focus on optimal nutrition and lean body mass (LBM) assessment, targeted nutrition delivery, anabolic/anticatabolic strategies, and utilization of personalized exercise intervention techniques, such as utilized by elite athletes to optimize preparation and recovery from critical care. New data for novel LBM analysis technique such as computerized tomography scan and ultrasound analysis of LBM are available showing objective measures of LBM now becoming more practical for predicting metabolic reserve and effectiveness of nutrition/exercise interventions. 13C-Breath testing is a novel technique under study to predict infection earlier and predict over-feeding and under-feeding to target nutrition delivery. New technologies utilized routinely by athletes such as muscle glycogen ultrasound also show promise. Finally, the role of personalized cardiopulmonary exercise testing to target preoperative exercise optimization and post-ICU recovery are becoming reality. New innovative techniques are demonstrating promise to target recovery from PICS utilizing a combination of objective LBM and metabolic assessment, targeted nutrition interventions, personalized exercise interventions for prehabilitation and post-ICU recovery. These interventions should provide hope that we will soon begin to create more 'survivors' and fewer victim's post-ICU

The purpose of this retrospective medical record review was to report on recidivism to the ICU among adult postoperative cardiac and thoracic patients managed with a respiratory therapy assess-and-treat (RTAT) protocol. Our primary null hypothesis was that there would be no difference in all-cause unexpected readmissions and escalations between the RTAT group and the physician-ordered respiratory care group. Our secondary null hypothesis was that there would be no difference in primary respiratory-related readmissions, ICU length of stay, or hospital length of stay. We reviewed 1,400 medical records of cardiac and thoracic postoperative subjects between January 2015 and October 2016. The RTAT is driven by a standardized patient assessment tool, which is completed by a registered respiratory therapist. The tool develops a respiratory severity score for each patient and directs interventions for bronchial hygiene, aerosol therapy, and lung inflation therapy based on an algorithm. The protocol period commenced on December 1, 2015, and continued through October 2016. Data relative to unplanned admissions to the ICU for all causes as well as respiratory-related causes were evaluated. There was a statistically significant difference in the all-cause unplanned ICU admission rate between the RTAT (5.8% [95% CI 4.3-7.9]) and the physician-ordered respiratory care (8.8% [95% CI 6.9-11.1]) groups ( P = .034). There was no statistically significant difference in respiratory-related unplanned ICU admissions with RTAT (36% [95% CI 22.7-51.6]) compared with the physician-ordered respiratory care (53% [95% CI 41.1-64.8]) group ( P = .09). The RTAT protocol group spent 1 d less in the ICU ( P < .001) and in the hospital ( P < .001). RTAT protocol implementation demonstrated a statistically significant reduction in all-cause ICU readmissions. The reduction in respiratory-related ICU readmissions did not reach statistical significance. Copyright © 2017 by Daedalus Enterprises.

The authors believe that as we move from viewing adverse event reporting system as punitive, and as the safety culture improves, reporting will likely increase. Voluntary incident reporting systems can be used to improve patient safety in the ICU by identifying broken or inadequate systems that lead to adverse events [26]. Voluntary external reporting systems such as the ICUSRS can be used to target errors and produce evidence-based best practice measures to improve patient safety in the ICU.

Purpose To estimate the costs and cost-effectiveness of a tele-ICU program. Materials and methods We used an observational study with ICU patients cared for during the pre-tele-ICU period and ICU patients cared for during the post-tele-ICU period in 6 ICUs at 5 hospitals, part of a large non-profit health care system in the Gulf Coast region. We obtained data on a sample of 4142 ICU patients: 2,034 in the pre-tele-ICU period and 2,108 in the post-tele-ICU period. Economic outcomes were hospital costs, ICU costs and floor costs, measured for average daily costs, costs per case, and costs per patient. Results After the implementation of the tele-ICU, the hospital daily cost increased from $4,302 to $5,340 (24%), the hospital cost per case from $21,967 to $31,318 (43%), and the cost per patient from $20,231 to $25,846 (28%). While the tele-ICU intervention was not cost effective in patients with SAPS II ≤ 50, it was cost effective in the sickest patients with SAPS II > 50 (17% of patients) as it decreased hospital mortality without increasing costs significantly. Conclusions Hospital administrators may conclude that a tele-ICU program aimed at the sickest patients is cost effective. PMID:21376515

The quality of information exchange between intensive care unit (ICU) and ward nurses, when patients are transferred out of intensive care, is important to the continuity of safe care. This research aimed to explore nurses' experiences of the discharge process from ICU to the ward environment. The study was conducted in a New Zealand Metropolitan hospital, using an exploratory descriptive design we adapted a questionnaire based on Whittaker and Ball's research on ICU patient handover. The questionnaires were then analysed using a descriptive thematic approach. The response rate of 48% included 45 ICU and 47 ward nurses. Key findings were that the written and verbal communication needs differ dependent upon setting and the timing of a discharge. Timing of handover also requires negotiation. Being able to negotiate the timing and nature of handover is important for nurses. In addition, standardized approaches to communication are believed to enhance patient safety. Standardized handover, with content and processes that are mutually negotiated, is crucial to providing the safest environment for patients. © 2013 The Authors.

To 1) describe factual, emotional, and delusional memories of ICU stay for patients enrolled in the SLEAP (Daily sedation interruption in mechanically ventilated critically ill patients cared for with a sedation protocol) trial; 2) compare characteristics of patients with and without ICU recall, and patients with and without delusional memories; and 3) determine factors associated with delusional memories 28 days after ICU discharge. Prospective cohort. Sixteen North American medical and surgical ICUs. Critically ill, mechanically ventilated adults randomized in the SLEAP trial. Post-ICU interviews on days 3, 28, and 90 using the validated ICU Memory Tool. Overall, 289 of 297 ICU survivors (97%) (146 protocolized sedation and 143 protocolized sedation plus daily interruption patients) were interviewed at least once. Because there were no differences in recall status or types of memories between the two sedation groups, we present the findings for all patients rather than by study group. On days 3, 28, and 90, 28%, 26%, and 36% of patients, respectively, reported no recall of being in the ICU (overall perception, self-reported) (p = 0.75). Mean daily doses of benzodiazepines and opioids were lower in patients with no ICU recall than those with recall (p < 0.0001 for both). Despite one third of patients reporting no recall of ICU stay on day 3, 97% and 90% reported at least one factual and one emotional memory from ICU, respectively. Emotional memories declined with time after ICU discharge, particularly panic and confusion. Delusional memories 28 days after discharge were common (70%) yet unrelated to delirium (p = 0.84), recall status (p = 0.15), total dose of benzodiazepine (p = 0.78), or opioid (p = 0.21). Delusional memories were less likely with longer duration of mechanical ventilation (odds ratio, 0.955; 95% CI, 0.91-1.00; p = 0.04). Recall of ICU stay and types of memories reported were not influenced by the trial sedation strategy. Lack of ICU recall and

The purposes of this study were to determine factors and predictors that influence nurses' intention to use the eICU technology, to examine the applicability of the Technology Acceptance Model in explaining nurses' intention to use the eICU technology in healthcare settings, and to provide psychometric evidence of the measurement scales used in the study. The study involved 117 participants from two healthcare systems. The Telemedicine Technology Acceptance Model was developed based on the original Technology Acceptance Model that was initially developed by Fred Davis in 1986. The eICU Acceptance Survey was used as an instrument for the study. Content validity was examined, and the reliability of the instrument was tested. The results show that perceived usefulness is the most influential factor that influences nurses' intention to use the eICU technology. The principal factors that influence perceived usefulness are perceived ease of use, support from physicians, and years working in the hospital. The model fit was reasonably adequate and able to explain 58% of the variance (R = 0.58) in intention to use the eICU technology with the nursing sample.

In this study researchers are trying to analyse the personality factors related to social skills in nurses who work in: Intensive Care Units, ICU, and Hospitalisation units. Both groups are from the Madrid Health Service (SERMAS). The present investigation has been developed as a descriptive transversal study, where personality factors in ICU nurses (n=29) and those from Hospitalisation units (n=40) were compared. The 16PF-5 questionnaire was employed to measure the personality factors associated with communication skills. The comparison of the personality factors associated to social skills, communication, in both groups, show us that nurses from ICU obtain in social receptivity: 5,6 (A+), 5,2 (C-), 6,2 (O+), 5,1 (H-), 5,3 (Q1-), and emotional control: 6,1 (B+), 5,9 (N+). Meanwhile the data doesn't adjust to the expected to emotional and social expressiveness, emotional receptivity and social control, there are not evidence. The personality factors associated to communication skills in ICU nurses are below those of hospitalisation unit nurses. The present results suggest the necessity to develop training actions, focusing on nurses from intensive care units to improve their communication social skills.

2010-01-01

Purpose Effective interdisciplinary exchange of patient information is an essential component of safe, efficient, and patient–centered care in the intensive care unit (ICU). Frequent handoffs of patient care, high acuity of patient illness, and the increasing amount of available data complicate information exchange. Verbal communication can be affected by interruptions and time limitations. To supplement verbal communication, many ICUs rely on documentation in electronic health records (EHRs) to reduce errors of omission and information loss. The purpose of this study was to develop a model of EHR interdisciplinary information exchange of ICU common goals. Methods The theoretical frameworks of distributed cognition and the clinical communication space were integrated and a previously published categorization of verbal information exchange was used. 59.5 hours of interdisciplinary rounds in a Neurovascular ICU were observed and five interviews and one focus group with ICU nurses and physicians were conducted. Results Current documentation tools in the ICU were not sufficient to capture the nurses' and physicians' collaborative decision-making and verbal communication of goal-directed actions and interactions. Clinicians perceived the EHR to be inefficient for information retrieval, leading to a further reliance on verbal information exchange. Conclusion The model suggests that EHRs should support: 1) Information tools for the explicit documentation of goals, interventions, and assessments with synthesized and summarized information outputs of events and updates; and 2) Messaging tools that support collaborative decision-making and patient safety double checks that currently occur between nurses and physicians in the absence of EHR support.

To evaluate a scheduled interprofessional huddle among pediatric residents, nursing staff, and cardiologists on the number of high-risk transfers to the ICU. A daily, night-shift huddle intervention was initiated between the in-house pediatric residents and nursing staff covering the cardiology ward patients with the at-home attending cardiologist. Retrospective cohort chart review identified high-risk transfers from the inpatient floor to the ICU over a 24-month period (eg, inotropic support, intubation, and/or respiratory support within 1 hour of ICU transfer). Satisfaction with the intervention and the impact of the intervention on team-based communication and resident education was collected using a retrospective pre-post survey. Ninety-three patients were identified as unscheduled transfers from the ward team to the ICU. Overall, 21 preintervention transfers were considered high risk, whereas only 8 patients were considered high risk after the intervention (P=.004). During the night shift, high risk transfers decreased from 8 of 17 (47%) to 3 of 21 patients (14%) (P=.03). Interprofessional communication improved with 12 of 14 nurses and 24 of 25 residents reporting effective communication after the intervention (P<.0001) compared with only 1 nurse and 15 residents reporting a positive experience before the intervention. Overall, all 3 provider groups stated an improved experience covering a high-risk cardiology patient population. Implementation of an interprofessional huddle may contribute to decreasing high-risk transfers to the ICU. Initiating a daily huddle was well received and allowed for open lines of communication across all provider groups. Copyright © 2016 by the American Academy of Pediatrics.

Pneumonia poses a significant burden to the U.S. health-care system. However, there are few data focusing on severe pneumonia, particularly cases of pneumonia associated with specialized care in intensive care units (ICU). We used administrative and electronic medical record data from six integrated health care systems to estimate rates of pneumonia hospitalizations with ICU admissions among adults during 2006 through 2010. Pneumonia hospitalization was defined as either a primary discharge diagnosis of pneumonia or a primary discharge diagnosis of sepsis or respiratory failure with a secondary diagnosis of pneumonia in administrative data. ICU admissions were collected from internal electronic medical records from each system. Comorbidities were identified by ICD-9-CM codes coded during the current pneumonia hospitalization, as well as during medical visits that occurred during the year prior to the date of admission. We identified 119,537 adult hospitalizations meeting our definition for pneumonia. Approximately 19% of adult pneumonia hospitalizations had an ICU admission. The rate of pneumonia hospitalizations requiring ICU admission during the study period was 76 per 100,000 population/year; rates increased for each age-group with the highest rates among adults aged ≥85 years. Having a co-morbidity approximately doubled the risk of ICU admission in all age-groups. Our study indicates a significant burden of pneumonia hospitalizations with an ICU admission among adults in our cohort during 2006 through 2010, especially older age-groups and persons with underlying medical conditions. These findings reinforce current strategies aimed to prevent pneumonia among adults.

Background: Limited data are available on the impact of time to ICU admission and outcomes for patients with severe community acquired pneumonia (CAP). Our objective was to examine the association of time to ICU admission and 30-day mortality in patients with severe CAP. Methods: A retrospective cohort study of 161 ICU subjects with CAP (by International Classification of Diseases, 9th edition, codes) was conducted over a 3-year period at two tertiary teaching hospitals. Timing of the ICU admission was dichotomized into early ICU admission (EICUA, direct admission or within 24 h) and late ICU admission (LICUA, ≥ day 2). A multivariable analysis using Cox proportional hazard model was created with the primary outcome of 30-day mortality (dependent measure) and the American Thoracic Society (ATS) severity adjustment criteria and time to ICU admission as the independent measures. Results: Eighty-eight percent (n = 142) were EICUA patients compared with 12% (n = 19) LICUA patients. Groups were similar with respect to age, gender, comorbidities, clinical parameters, CAP-related process of care measures, and need for mechanical ventilation. LICUA patients had lower rates of ATS severity criteria at presentation (26.3% vs 53.5%; P = .03). LICUA patients (47.4%) had a higher 30-day mortality compared with EICUA (23.2%) patients (P = .02), which remained after adjusting in the multivariable analysis (hazard ratio 2.6; 95% CI, 1.2-5.5; P = .02). Conclusion: Patients with severe CAP with a late ICU admission have increased 30-day mortality after adjustment for illness severity. Further research should evaluate the risk factors associated and their impact on clinical outcomes in patients admitted late to the ICU. PMID:19880910

ICU admission delays can negatively affect patient outcomes, but emergency department volume and boarding times may also affect these decisions and associated patient outcomes. We sought to investigate the effect of emergency department and ICU capacity strain on ICU admission decisions and to examine the effect of emergency department boarding time of critically ill patients on in-hospital mortality. A retrospective cohort study. Single academic tertiary care hospital. Adult critically ill emergency department patients for whom a consult for medical ICU admission was requested, over a 21-month period. None. Patient data, including severity of illness (Mortality Probability Model III on Admission), outcomes of mortality and persistent organ dysfunction, and hourly census reports for the emergency department, for all ICUs and all adult wards were compiled. A total of 854 emergency department requests for ICU admission were logged, with 455 (53.3%) as "accept" and 399 (46.7%) as "deny" cases, with median emergency department boarding times 4.2 hours (interquartile range, 2.8-6.3 hr) and 11.7 hours (3.2-20.3 hr) and similar rates of persistent organ dysfunction and/or death 41.5% and 44.6%, respectively. Those accepted were younger (mean ± SD, 61 ± 17 vs 65 ± 18 yr) and more severely ill (median Mortality Probability Model III on Admission score, 15.3% [7.0-29.5%] vs 13.4% [6.3-25.2%]) than those denied admission. In the multivariable model, a full medical ICU was the only hospital-level factor significantly associated with a lower probability of ICU acceptance (odds ratio, 0.55 [95% CI, 0.37-0.81]). Using propensity score analysis to account for imbalances in baseline characteristics between those accepted or denied for ICU admission, longer emergency department boarding time after consult was associated with higher odds of mortality and persistent organ dysfunction (odds ratio, 1.77 [1.07-2.95]/log10 hour increase).

Blood culture is routinely taken at the time of admission to the intensive care unit (ICU) for patients suspected to have infection. We undertook this study to determine the incidence of bacteremia at the time of ICU admission and to assess its impact on the outcome. Retrospective cohort study from all the admissions in ICU, in whom blood cultures sent at the time of admission were analyzed. Data regarding patient demographics, probable source of infection, previous antibiotic use and ICU course was recorded. Severity of illness on admission was assessed by acute physiology and chronic health evaluation II score. Qualitative data were analyzed using Chi-square or Fisher Exact test and quantitative data were analyzed using Student's t-test. Primary outcome measure was ICU mortality. Of 567 patients, 42% patients were on antibiotics. Sixty-four percent of the patients were direct ICU admission from casualty, 10.76% were from wards and 6.17% from other ICUs, and 19.05% were transfers from other hospitals. Blood cultures were positive in 10.6% patients. Mortality was significantly higher in patients with positive blood cultures (45% vs. 13.6%; P=0.000). On univariate analysis, only previous antibiotic use was statistically associated with higher mortality (P=0.011). Bacteremic patients who were already on antibiotics had a significantly higher mortality (OR 12.9, 95% CI: 1.6-100). Blood cultures may be positive in only minority of the patients with suspected infection admitted to ICU. Nevertheless, the prognosis of those patients with positive blood culture is worse, especially if culture is positive in spite of the patient being on antibiotics.

Good quality indicators should have face validity, relevance to patients, and be able to be measured reliably. Beyond these general requirements, good quality indicators should also have certain statistical properties, including sufficient variability to identify poor performers, relative insensitivity to severity adjustment, and the ability to capture what providers do rather than patients' characteristics. We assessed the performance of candidate indicators of ICU quality on these criteria. Indicators included ICU readmission, mortality, several length of stay outcomes, and the processes of venous-thromboembolism and stress ulcer prophylaxis provision. Retrospective cohort study. One hundred thirty-eight U.S. ICUs from 2001-2008 in the Project IMPACT database. Two hundred sixty-eight thousand eight hundred twenty-four patients discharged from U.S. ICUs. None. We assessed indicators' (1) variability across ICU-years; (2) degree of influence by patient vs. ICU and hospital characteristics using the Omega statistic; (3) sensitivity to severity adjustment by comparing the area under the receiver operating characteristic curve (AUC) between models including vs. excluding patient variables, and (4) correlation between risk adjusted quality indicators using a Spearman correlation. Large ranges of among-ICU variability were noted for all quality indicators, particularly for prolonged length of stay (4.7-71.3%) and the proportion of patients discharged home (30.6-82.0%), and ICU and hospital characteristics outweighed patient characteristics for stress ulcer prophylaxis (ω, 0.43; 95% CI, 0.34-0.54), venous thromboembolism prophylaxis (ω, 0.57; 95% CI, 0.53-0.61), and ICU readmissions (ω, 0.69; 95% CI, 0.52-0.90). Mortality measures were the most sensitive to severity adjustment (area under the receiver operating characteristic curve % difference, 29.6%); process measures were the least sensitive (area under the receiver operating characteristic curve % differences

The ability of medical teams to develop and maintain team situation awareness (team SA) is crucial for patient safety. Limited research has investigated team SA within clinical environments. This study reports the development of a method for investigating team SA during the intensive care unit (ICU) round and describes the results. In one ICU, a sample of doctors and nurses (n = 44, who combined to form 37 different teams) were observed during 34 morning ward rounds. Following the clinical review of each patient (n = 105), team members individually recorded their anticipations for expected patient developments over 48 h. Patient-outcome data were collected to determine the accuracy of anticipations. Anticipations were compared among ICU team members, and the degree of consensus was used as a proxy measure of team SA. Self-report and observational data measured team-member involvement and communication during patient reviews. For over half of 105 patients, ICU team members formed conflicting anticipations as to whether patients would deteriorate within 48 h. Senior doctors were most accurate in their predictions. Exploratory analysis found that team processes did not predict team SA. However, the involvement of junior and senior trainee doctors in the patient decision-making process predicted the extent to which those team members formed team SA with senior doctors. A new method for measuring team SA during the ICU round was successfully employed. A number of areas for future research were identified, including refinement of the situation awareness and teamwork measures.

Implications of ICU triage decisions on patient mortality: a cost-effectiveness analysis

PubMed Central

2011-01-01

Introduction Intensive care is generally regarded as expensive, and as a result beds are limited. This has raised serious questions about rationing when there are insufficient beds for all those referred. However, the evidence for the cost effectiveness of intensive care is weak and the work that does exist usually assumes that those who are not admitted do not survive, which is not always the case. Randomised studies of the effectiveness of intensive care are difficult to justify on ethical grounds; therefore, this observational study examined the cost effectiveness of ICU admission by comparing patients who were accepted into ICU after ICU triage to those who were not accepted, while attempting to adjust such comparison for confounding factors. Methods This multi-centre observational cohort study involved 11 hospitals in 7 EU countries and was designed to assess the cost effectiveness of admission to intensive care after ICU triage. A total of 7,659 consecutive patients referred to the intensive care unit (ICU) were divided into those accepted for admission and those not accepted. The two groups were compared in terms of cost and mortality using multilevel regression models to account for differences across centres, and after adjusting for age, Karnofsky score and indication for ICU admission. The analyses were also stratified by categories of Simplified Acute Physiology Score (SAPS) II predicted mortality (< 5%, 5% to 40% and >40%). Cost effectiveness was evaluated as cost per life saved and cost per life-year saved. Results Admission to ICU produced a relative reduction in mortality risk, expressed as odds ratio, of 0.70 (0.52 to 0.94) at 28 days. When stratified by predicted mortality, the odds ratio was 1.49 (0.79 to 2.81), 0.7 (0.51 to 0.97) and 0.55 (0.37 to 0.83) for <5%, 5% to 40% and >40% predicted mortality, respectively. Average cost per life saved for all patients was $103,771 (€82,358) and cost per life-year saved was $7,065 (€5,607). These

Objective The aim of the present study was to translate and cross-culturally adapt the Functional Status Score for the intensive care unit (FSS-ICU) into Brazilian Portuguese. Methods This study consisted of the following steps: translation (performed by two independent translators), synthesis of the initial translation, back-translation (by two independent translators who were unaware of the original FSS-ICU), and testing to evaluate the target audience's understanding. An Expert Committee supervised all steps and was responsible for the modifications made throughout the process and the final translated version. Results The testing phase included two experienced physiotherapists who assessed a total of 30 critical care patients (mean FSS-ICU score = 25 ± 6). As the physiotherapists did not report any uncertainties or problems with interpretation affecting their performance, no additional adjustments were made to the Brazilian Portuguese version after the testing phase. Good interobserver reliability between the two assessors was obtained for each of the 5 FSS-ICU tasks and for the total FSS-ICU score (intraclass correlation coefficients ranged from 0.88 to 0.91). Conclusion The adapted version of the FSS-ICU in Brazilian Portuguese was easy to understand and apply in an intensive care unit environment. PMID:28444070

Advances in intensive care medicine have enormously improved ability to successfully treat seriously ill patients. However, intensive treatment and prolongation of life is not always in the patient's best interest, and many ethical dilemmas arise in end-of-life (EOL) situations. We aimed to assess intensive care unit (ICU) physicians' experiences with EOL decision making and to compare the responses according to ICU type. A cross-sectional survey was performed in all 35 Slovene ICUs, using a questionnaire designed to assess ICU physician experiences with EOL decision making, focusing on limitations of life-sustaining treatments (LST). We distributed 370 questionnaires (approximating the number of Slovene ICU physicians) and 267 were returned (72% response rate). The great majority of ICU physicians reported using do-not-resuscitate (DNR) orders (97%), withholding LST (94%), and withdrawing antibiotics (86%) or inotropes (95%). Fewer ICU physicians reported withdrawing mechanical ventilation (52%) or extubating patients (27%). Hydration was reported to be only rarely terminated (76% of participants reported never terminating it). In addition, 63% of participants had never encountered advance directives, and 39% reported to "never" or "rarely" participating in decision making with relatives of patients. Nurses were reported to be "never" or "rarely" involved in the EOL decision making process by 84% of participants. Limitation of LST was regularly used by Slovene ICU physicians. DNR orders and withholding of LST were the most commonly used measures. Hydration was only rarely terminated. In addition, use of advance directives was almost non-existent in practice, and the patients' relatives and nurses only infrequently participated in the decision making.

Music intervention has been shown to reduce anxiety and sedative exposure among mechanically ventilated patients. Whether music intervention reduces ICU costs is not known. The aim of this study was to examine ICU costs for patients receiving a patient-directed music intervention compared with patients who received usual ICU care. A cost-effectiveness analysis from the hospital perspective was conducted to determine if patient-directed music intervention was cost-effective in improving patient-reported anxiety. Cost savings were also evaluated. One-way and probabilistic sensitivity analyses determined the influence of input variation on the cost-effectiveness. Midwestern ICUs. Adult ICU patients from a parent clinical trial receiving mechanical ventilatory support. Patients receiving the experimental patient-directed music intervention received a MP3 player, noise-canceling headphones, and music tailored to individual preferences by a music therapist. The base case cost-effectiveness analysis estimated patient-directed music intervention reduced anxiety by 19 points on the Visual Analogue Scale-Anxiety with a reduction in cost of $2,322/patient compared with usual ICU care, resulting in patient-directed music dominance. The probabilistic cost-effectiveness analysis found that average patient-directed music intervention costs were $2,155 less than usual ICU care and projected that cost saving is achieved in 70% of 1,000 iterations. Based on break-even analyses, cost saving is achieved if the per-patient cost of patient-directed music intervention remains below $2,651, a value eight times the base case of $329. Patient-directed music intervention is cost-effective for reducing anxiety in mechanically ventilated ICU patients.

Exponential surge in health care data, such as longitudinal data from electronic health records (EHR), sensor data from intensive care unit (ICU), etc., is providing new opportunities to discover meaningful data-driven characteristics and patterns ofdiseases. Recently, deep learning models have been employedfor many computational phenotyping and healthcare prediction tasks to achieve state-of-the-art performance. However, deep models lack interpretability which is crucial for wide adoption in medical research and clinical decision-making. In this paper, we introduce a simple yet powerful knowledge-distillation approach called interpretable mimic learning, which uses gradient boosting trees to learn interpretable models and at the same time achieves strong prediction performance as deep learning models. Experiment results on Pediatric ICU dataset for acute lung injury (ALI) show that our proposed method not only outperforms state-of-the-art approaches for morality and ventilator free days prediction tasks but can also provide interpretable models to clinicians.

Objective To evaluate the internal consistency, validity, responsiveness, and minimal important difference of the Functional Status Score for the Intensive Care Unit (FSS-ICU), a physical function measure designed for the intensive care unit (ICU). Design Clinimetric analysis. Settings Five international data sets from the United States, Australia, and Brazil. Patients 819 ICU patients. Intervention None. Measurements and Main Results Clinimetric analyses were initially conducted separately for each data source and time point to examine generalizability of findings, with pooled analyses performed thereafter to increase power of analyses. The FSS-ICU demonstrated good to excellent internal consistency. There was good convergent and discriminant validity, with significant and positive correlations (r = 0.30 to 0.95) between FSS-ICU and other physical function measures, and generally weaker correlations with non-physical measures (|r| = 0.01 to 0.70). Known group validity was demonstrated by significantly higher FSS-ICU scores among patients without ICU-acquired weakness (Medical Research Council sumscore ≥48 versus <48) and with hospital discharge to home (versus healthcare facility). FSS-ICU at ICU discharge predicted post-ICU hospital length of stay and discharge location. Responsiveness was supported via increased FSS-ICU scores with improvements in muscle strength. Distribution-based methods indicated a minimal important difference of 2.0 to 5.0. Conclusions The FSS-ICU has good internal consistency and is a valid and responsive measure of physical function for ICU patients. The estimated minimal important difference can be used in sample size calculations and in interpreting studies comparing the physical function of groups of ICU patients. PMID:27488220

Intensive care unit (ICU) scoring systems or prediction models evolved to meet the desire of clinical and administrative leaders to assess the quality of care provided by their ICUs. The Critical Care Information System (CCIS) is province-wide data information for all Ontario, Canada level 3 and level 2 ICUs collected for this purpose. With the dataset, we developed a multivariable logistic regression ICU mortality prediction model during the first 24 h of ICU admission utilizing the explanatory variables including the two validated scores, Multiple Organs Dysfunctional Score (MODS) and Nine Equivalents Nursing Manpower Use Score (NEMS) followed by the variables age, sex, readmission to the ICU during the same hospital stay, admission diagnosis, source of admission, and the modified Charlson Co-morbidity Index (CCI) collected through the hospital health records. This study is a single-center retrospective cohort review of 8822 records from the Critical Care Trauma Centre (CCTC) and Medical-Surgical Intensive Care Unit (MSICU) of London Health Sciences Centre (LHSC), Ontario, Canada between 1 Jan 2009 to 30 Nov 2012. Multivariable logistic regression on training dataset (n = 4321) was used to develop the model and validate by bootstrapping method on the testing dataset (n = 4501). Discrimination, calibration, and overall model performance were also assessed. The predictors significantly associated with ICU mortality included: age (p < 0.001), source of admission (p < 0.0001), ICU admitting diagnosis (p < 0.0001), MODS (p < 0.0001), and NEMS (p < 0.0001). The variables sex and modified CCI were not significantly associated with ICU mortality. The training dataset for the developed model has good discriminating ability between patients with high risk and those with low risk of mortality (c-statistic 0.787). The Hosmer and Lemeshow goodness-of-fit test has a strong correlation between the observed and expected ICU mortality (χ (2) = 5

To analyze the prognosis of mechanically ventilated elderly patients in the Intensive Care Unit (ICU). Sub-analysis of a prospective multicenter observational cohort study conducted over a period of two years in 13 medical-surgical ICUs in Spain. Adult patients who required mechanical ventilation (MV) for longer than 24 hours. None. Demographic data, APACHE II, SOFA, reason for MV, comorbidity, functional condition, reintubation, duration of MV, tracheotomy, ICU mortality, in-hospital mortality. A total of 1661 patients were recruited. Males accounted for 67.9% (n=1127), with a mean age of 62.1 ± 16.2 years. APACHE II: 20.3 ± 7.5. Total SOFA: 8.4 ± 3.5. Four hundred and twenty-three patients (25.4%) were ≥ 75 years of age. Comorbidity and functional condition rates were poorer in these patients (p<0.001 for both variables). Mortality in the ICU was higher in the elderly patients (33.6%) than in the younger subjects (25.9%) (p=0.002). Also, in-hospital mortality was higher in those ≥ 75 years of age. No differences in duration of MV, prevalence of tracheostomy or reintubation incidence were found. Regarding the indication for MV, only the patient ≥ 75 years of age with pneumonia, sepsis or trauma had a higher in-ICU mortality than the younger patients (46.3% vs 33.1%, p=0.006; 55% vs 25.8%, p=0.002; 63.6% vs 4.5%, p<0,001, respectively). No differences were found referred to other reasons for MV. Older patients (≥ 75 years) have significantly higher in-ICU and in-hospital mortality than younger patients without differences in the duration of mechanical ventilation. Differences in mortality were at the expense of pneumonia, sepsis and trauma. Copyright © 2012 Elsevier España, S.L. and SEMICYUC. All rights reserved.

We hypothesized that continuous, automatic turning utilizing a patient-friendly, low air loss surface would reduce the incidence of early ICU pneumonia in selected groups of critically ill medical patients. Prospective, randomized, controlled clinical trial. Medical ICU of a large community teaching hospital. One hundred twenty-four critically ill new admissions to the medical ICU at Charity Hospital in New Orleans. Patients were prospectively randomized within one of five diagnosis-related groups (DRG)--sepsis (SEPSIS), obstructive airways disease (OAD), metabolic coma, drug overdose, and stroke--to either routine turning on a standard ICU bed or to continuous turning on an oscillating air-flotation bed for a total of five days. Patients were monitored daily during the treatment period for the development of pneumonia. The incidence of pneumonia during the first five ICU days was 22 percent in patients randomized to the standard ICU bed vs 9 percent for the oscillating bed (p = 0.05). This treatment effect was greatest in the SEPSIS DRG (23 percent vs 3 percent, p = 0.04). Continuous automatic oscillation did not significantly change the number of days of required mechanical ventilation, ICU stay, hospital stay, or hospital mortality overall or within any of the DRGs. We conclude that air-supported automated turning during the first five ICU days reduces the incidence of early ICU pneumonia in selected DRGs; however, this form of automated turning does not reduce other measured clinical outcome parameters.

The aim of this study was to characterize the pharmacokinetics (PK) of propofol in ICU patients undergoing long-term sedation and to assess the influence of routinely collected covariates on the PK parameters. Propofol concentration-time profiles were collected from 29 patients. Non-linear mixed-effects modelling in NONMEM 7.2 was used to analyse the observed data. The propofol pharmacokinetics was best described with a three-compartment disposition model. Non-parametric bootstrap and a visual predictive check were used to evaluate the adequacy of the developed model to describe the observations. The typical value of the propofol clearance (1.46 l/min) approximated the hepatic blood flow. The volume of distribution at steady state was high and was equal to 955.1 l, which is consistent with other studies involving propofol in ICU patients. There was no statistically significant covariate relationship between PK parameters and opioid type, SOFA score on the day of admission, APACHE II, predicted death rate, reason for ICU admission (sepsis, trauma or surgery), gender, body weight, age, infusion duration and C-reactive protein concentration. The population PK model was developed successfully to describe the time-course of propofol concentration in ICU patients undergoing prolonged sedation. Despite a very heterogeneous group of patients, consistent PK profiles were observed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Development and evaluation of Intensive Care Unit (ICU) decision-support systems would be greatly facilitated by the availability of a large-scale ICU patient database. Following our previous efforts with the MIMIC (Multi-parameter Intelligent Monitoring for Intensive Care) Database, we have leveraged advances in networking and storage technologies to develop a far more massive temporal database, MIMIC II. MIMIC II is an ongoing effort: data is continuously and prospectively archived from all ICU patients in our hospital. MIMIC II now consists of over 800 ICU patient records including over 120 gigabytes of data and is growing. A customized archiving system was used to store continuously up to four waveforms and 30 different parameters from ICU patient monitors. An integrated user-friendly relational database was developed for browsing of patients' clinical information (lab results, fluid balance, medications, nurses' progress notes). Based upon its unprecedented size and scope, MIMIC II will prove to be an important resource for intelligent patient monitoring research, and will support efforts in medical data mining and knowledge-discovery.

Tight glycemic control in the ICU - is the earth flat?

PubMed

Steil, Garry M; Agus, Michael S D

2014-06-27

Tight glycemic control in the ICU has been shown to reduce mortality in some but not all prospective randomized control trials. Confounding the interpretation of these studies are differences in how the control was achieved and underlying incidence of hypoglycemia, which can be expected to be affected by the introduction of continuous glucose monitoring (CGM). In this issue of Critical Care, a consensus panel provides a list of the research priorities they believe are needed for CGM to become routine practice in the ICU. We reflect on these recommendations and consider the implications for using CGM today.

To investigate family perceptions of having a nurse participating in family conferences and to assess the psychologic well being of the same families after ICU discharge. Mixed-method design with a qualitative study embedded in a single-center randomized study. Twelve-bed medical-surgical ICU in a 460-bed tertiary hospital. One family member for each consecutive patient who received more than 48 hours of mechanical ventilation in the ICU. Planned proactive participation of a nurse in family conferences led by a physician. In the control group, conferences were led by a physician without a nurse. Of the 172 eligible family members, 100 (60.2%) were randomized; among them, 88 underwent semistructured interviews at ICU discharge and 86 completed the Peritraumatic Dissociative Experiences Questionnaire at ICU discharge and then the Hospital Anxiety Depression Questionnaire and the Impact of Event Scale (for posttraumatic stress-related symptoms) 3 months later. The intervention and control groups were not significantly different regarding the prevalence of posttraumatic stress-related symptoms (52.3 vs 50%, respectively; p = 0.83). Anxiety and depression subscale scores were significantly lower in the intervention group. The qualitative data indicated that the families valued the principle of the conference itself. Perceptions of nurse participation clustered into four main themes: trust that ICU teamwork was effective (50/88; 56.8%), trust that care was centered on the patient (33/88; 37.5%), trust in effective dissemination of information (15/88; 17%), and trust that every effort was made to relieve anxiety in family members (12/88; 13.6%). Families valued the conferences themselves and valued the proactive participation of a nurse. These positive perceptions were associated with significant anxiety or depression subscale scores but not with changes in posttraumatic stress-related symptoms.

Accurately communicating patient data during daily ICU rounds is critically important since data provide the basis for clinical decision making. Despite its importance, high fidelity data communication during interprofessional ICU rounds is assumed, yet unproven. We created a robust but simple methodology to measure the prevalence of inaccurately communicated (misrepresented) data and to characterize data communication failures by type. We also assessed how commonly the rounding team detected data misrepresentation and whether data communication was impacted by environmental, human, and workflow factors. Direct observation of verbalized laboratory data during daily ICU rounds compared with data within the electronic health record and on presenters' paper prerounding notes. Twenty-six-bed academic medical ICU with a well-established electronic health record. ICU rounds presenter (medical student or resident physician), interprofessional rounding team. None. During 301 observed patient presentations including 4,945 audited laboratory results, presenters used a paper prerounding tool for 94.3% of presentations but tools contained only 78% of available electronic health record laboratory data. Ninty-six percent of patient presentations included at least one laboratory misrepresentation (mean, 6.3 per patient) and 38.9% of all audited laboratory data were inaccurately communicated. Most misrepresentation events were omissions. Only 7.8% of all laboratory misrepresentations were detected. Despite a structured interprofessional rounding script and a well-established electronic health record, clinician laboratory data retrieval and communication during ICU rounds at our institution was poor, prone to omissions and inaccuracies, yet largely unrecognized by the rounding team. This highlights an important patient safety issue that is likely widely prevalent, yet underrecognized.

At 5:30 pm on December 17, 2010, shortly after a power failure, smoke filled the Intensive Care Unit (ICU) of Federico II University Hospital in Naples, Italy, triggering the hospital emergency alarm system. Immediately, staff began emergency procedures and alerted rescue teams. All patients were transferred without harm. The smoke caused pharyngeal and conjunctival irritation in some staff members. After a brief investigation, firefighters discovered the cause of the fire was a failure of the Uninterruptible Power Supply (UPS).

It is recommended that critically ill patients undergo routine delirium monitoring with a valid and reliable tool such as the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). However, the validity and reliability of the Arabic version of the CAM-ICU has not been investigated. Here, we test the validity and reliability of the Arabic CAM-ICU. We conducted a psychometric study at ICUs in a tertiary-care hospital in Saudi Arabia. We recruited consecutive adult Arabic-speaking patients, who had stayed in the ICU for at least 24 hours, and had a Richmond Agitation-Sedation Scale (RASS) score ≥ - 2 at examination. Two well-trained examiners (ICU nurse and intensivist) independently assessed delirium in eligible patients with the Arabic CAM-ICU. Evaluations by the two examiners were compared with psychiatrist blind clinical assessment of delirium according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Subgroup analyses were conducted for age, invasive mechanical ventilation, and gender. We included 108 patients (mean age: 62.6 ± 17.6; male: 51.9%), of whom 37% were on invasive mechanical ventilation. Delirium was diagnosed in 63% of enrolled patients as per the psychiatrist clinical assessment. The Arabic CAM-ICU sensitivity was 74% (95% confidence interval [CI] = 0.63-0.84) and 56% (95%CI = 0.44-0.68) for the ICU nurse and intensivist, respectively. Specificity was 98% (95%CI = 0.93-1.0) and 92% (95%CI = 0.84-1.0), respectively. Sensitivity was greater for mechanically-ventilated patients, women, and those aged ≥65 years. Specificity was greater for those aged < 65 years, non-mechanically-ventilated patients and men. The median duration to complete the Arabic CAM-ICU was 2 min (interquartile range, 2-3) and 4.5 min (IQR, 3-5) for the ICU nurse and intensivist, respectively. Inter-rater reliability (kappa) was 0.66. The Arabic CAM-ICU demonstrated acceptable reliability and

Selective digestive decontamination (SDD) and selective oropharyngeal decontamination (SOD) improved intensive care unit (ICU), hospital and 28-day survival in ICUs with low levels of antibiotic resistance. Yet it is unclear whether the effect differs between medical and surgical ICU patients. In an individual patient data meta-analysis, we systematically searched PubMed and included all randomized controlled studies published since 2000. We performed a two-stage meta-analysis with separate logistic regression models per study and per outcome (hospital survival and ICU survival) and subsequent pooling of main and interaction effects. Six studies, all performed in countries with low levels of antibiotic resistance, yielded 16 528 hospital admissions and 17 884 ICU admissions for complete case analysis. Compared to standard care or placebo, the pooled adjusted odds ratios for hospital mortality was 0.82 (95% confidence interval (CI) 0.72-0.93) for SDD and 0.84 (95% CI 0.73-0.97) for SOD. Compared to SOD, the adjusted odds ratio for hospital mortality was 0.90 (95% CI 0.82-0.97) for SDD. The effects on hospital mortality were not modified by type of ICU admission (p values for interaction terms were 0.66 for SDD and control, 0.87 for SOD and control and 0.47 for SDD and SOD). Similar results were found for ICU mortality. In ICUs with low levels of antibiotic resistance, the effectiveness of SDD and SOD was not modified by type of ICU admission. SDD and SOD improved hospital and ICU survival compared to standard care in both patient populations, with SDD being more effective than SOD. Copyright © 2017 The Author(s).

[Telemedicine in the ICU - the possibilities and limitations of an innovation].

Deisz, R; Marx, G

2016-11-01

Intensive care medicine is challenged by demographic changes and an increasing number of patient combined with existing shortage of doctors. Telemedicine is a promising approach to ensure patient care in the coming years. Due to a shortage of intensive care physicians in the USA, comprehensive telemedicine coverage has already been established. To date, 11 % of all hospitals are supported by a telemedicine center. The beneficial impact in terms of quality of care, patient safety and economic factors has been confirmed in numerous multicenter studies. In the largest multicenter study by Lilly et al., including 107,432 critically ill patients in the intervention group, telemedicine interventions led to a reduced ICU and hospital mortality. In addition, tele-consulting significantly reduced the ICU- and hospital length of stay. These findings were further supported by following studies and metaanalysis, which confirmed these results. The incidence of ventilator-associated pneumonia and catheter-associated infections was significantly reduced, when compared to the preintervention group. Furthermore, patient safety and treatment outcomes were improved by increased guideline adherence. Last, the telemedicine intervention significantly decreased the overall treatment costs. These positive results were reproducible even in larger and academic hospitals. At the same time it should be pointed out that a transfer to other health care systems should be considered cautiously in the context of different local infrastructure and culture. Finally, it has to be investigated to what extent the results can be transferred to the health-care situation in Germany. Previous data demonstrated that telemedical support can improve the outcome in critically ill patients, both during hospitalization as well as in the long-term result until the discharge home. Telemedicine is neither a magic bullet nor a replacement for a physician. Instead it is a new type of medical cooperation

Periodontal infection is a possible risk factor for respiratory disorders; however, no studies have assessed the colonization of periodontal pathogens in endotracheal tubes (ET). This case-control study analyzed whether periodontal pathogens are able to colonize ET of dentate and edentulous patients in intensive care units (ICU) and whether oral and ET periodontal pathogen profiles have any correlation between these patients. We selected 18 dentate and 18 edentulous patients from 78 eligible ICU patients. Oral clinical examination including probing depth, clinical attachment level, gingival index , and plaque index was performed by a single examiner, followed by oral and ET sampling and processing by quantitative polymerase chain reaction (total bacterial load, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia). Data were statistically analyzed by Mann-Whitney U, two-way analysis of variance (p < 0.05). Among dentate, there was no correlation between clinical parameters and ET bacterial levels. Both dentate and edentulous patients showed similar ET bacterial levels. Dentate patients showed no correlation between oral and ET bacterial levels, while edentulous patients showed positive correlations between oral and ET levels of A. actinomycetemcomitans, P. gingivalis, and T. forsythia. Periodontal pathogens can colonize ET and the oral cavity of ICU patients. Periodontal pathogen profiles tend to be similar between dentate and edentulous ICU patients. In ICU patients, oral cavity represents a source of ET contamination. Although accompanied by higher oral bacterial levels, teeth do not seem to influence ET bacterial profiles.

To perform a serial assessment and compare ability in predicting the intensive care unit (ICU) mortality of the multiple organ dysfunction score (MODS), sequential organ failure assessment (SOFA) and logistic organ dysfunction (LOD) score. The data were collected prospectively on consecutive ICU admissions over a 24-month period at a tertiary referral university hospital. The MODS, SOFA, and LOD scores were calculated on initial and repeated every 24 hrs. Two thousand fifty four patients were enrolled in the present study. The maximum and delta-scores of all the organ dysfunction scores correlated with ICU mortality. The maximum score of all models had better ability for predicting ICU mortality than initial or delta score. The areas under the receiver operating characteristic curve (AUC) for maximum scores was 0.892 for the MODS, 0.907 for the SOFA, and 0.92for the LOD. No statistical difference existed between all maximum scores and Acute Physiology and Chronic Health Evaluation II (APACHE II) score. Serial assessment of organ dysfunction during the ICU stay is reliable with ICU mortality. The maximum scores is the best discrimination comparable with APACHE II score in predicting ICU mortality.

Early nutritional support is an essential component of burn care to prevent ileus, stress ulceration, and the effects of hypermetabolism. The American Burn Association practice guidelines state that enteral feedings should be initiated as soon as practical. The authors sought to evaluate compliance with early enteral nutrition (EN) guidelines, associated complications, and hospitalization outcomes in a prospective multicenter observational study. They conducted a retrospective review of mechanically ventilated burn patients enrolled in the prospective observational multicenter study “Inflammation and the Host Response to Injury.” Timing of initiation of tube feedings was recorded, with early EN defined as being started within 24 hours of admission. Univariate and multivariate analyses were performed to distinguish barriers to initiation of EN and the impact of early feeding on development of multiple organ dysfunction syndrome, infectious complications, days on mechanical ventilation, intensive care unit (ICU) length of stay, and survival. A total of 153 patients met study inclusion criteria. The cohort comprised 73% men, with a mean age of 41 ± 15 years and a mean %TBSA burn of 46 ± 18%. One hundred twenty-three patients (80%) began EN in the first 24 hours and 145 (95%) by 48 hours. Age, sex, inhalation injury, and full-thickness burn size were similar between those fed by 24 hours vs after 24 hours, except for higher mean Acute Physiology and Chronic Health Evaluation II scores (26 vs 23, P = .03) and smaller total burn size (44 vs 54% TBSA burn, P = .01) in those fed early. There was no significant difference in rates of hyperglycemia, abdominal compartment syndrome, or gastrointestinal bleeding between groups. Patients fed early had shorter ICU length of stay (adjusted hazard ratio 0.57, P = 0.03, 95% confidence interval 0.35–0.94) and reduced wound infection risk (adjusted odds ratio 0.28, P = 0.01, 95% confidence interval 0.10–0.76).

Intensive care unit (ICU)-acquired weakness is common and characterized by muscle loss, weakness, and paralysis. It is associated with poor short-term outcomes, including increased mortality, but the consequences of reduced long-term outcomes, including decreased physical function and quality of life, can be just as devastating. ICU-acquired weakness is particularly relevant to elderly patients who are increasingly consuming ICU resources and are at increased risk for ICU-acquired weakness and complications, including mortality. Elderly patients often enter critical illness with reduced muscle mass and function and are also at increased risk for accelerated disuse atrophy with acute illness. Increasingly, intensivists and researchers are focusing on strategies and therapies aimed at improving long-term neuromuscular function. β-Hydroxy-β-methylbutyrate (HMB), an ergogenic supplement, has shown efficacy in elderly patients and certain clinical populations in counteracting muscle loss. The present review discusses ICU-acquired weakness, as well as the unique physiology of muscle loss and skeletal muscle function in elderly patients, and then summarizes the evidence for HMB in elderly patients and in clinical populations. We subsequently postulate on the potential role and strategies in studying HMB in elderly ICU patients to improve muscle mass and function. © 2013 American Society for Parenteral and Enteral Nutrition.

Improving the Patient Experience by Implementing an ICU Diary for Those at Risk of Post-intensive Care Syndrome.

The critical care literature in the US has recently brought attention to the impact an ICU experience can have long after the patient survives critical illness, particularly if delirium was present. Current recommendations to mitigate post-intensive care syndrome (PICS) are embedded in patient and family-centered care and aim to promote family presence in the ICU, provide support for decision-making, and enhance communication with the health-care team. Evidence-based interventions are few in number but include use of an ICU diary to minimize the psychological and emotional sequelae affecting patients and family members in the months following the ICU stay. In this paper we describe our efforts to implement an ICU diary and solicit feedback on its role in fostering teamwork and communication between patients, family members, and ICU staff. Next steps will involve a PICS follow-up clinic where trained staff will coordinate specialty referrals and perform long-term monitoring of mental health and other quality of life outcomes.

The purpose of this study was to describe the oral-care practices of ICU nurses, to compare those practices with current evidence-based practice, and to determine if the use of evidence-based practice was associated with personal demographic or professional characteristics. A national survey of oral-care practices of ICU nurses was conducted using a convenience sample of 218 practicing ICU nurses in 2004-05. The survey instrument included questions about demographic and professional characteristics and a checklist of oral-care practices. Nurses rated their perceived level of priority concerning oral care on a scale from 0 to 100. A score was computed representing the sum of 14 items related to equipment, solutions, assessments, and techniques associated with the current best evidence. This score was then statistically analyzed using ANOVA to determine differences of EBP based on demographic and professional characteristics. The most commonly used equipment was gauze pads (84%), followed by tongue depressors (55%), and toothbrushes (34%). Chlorhexidine was the most common solution used (75%). Less than half (44%) reported brushing their patients' teeth. The majority performed an oral assessment before beginning oral care (71%); however, none could describe what assessment tool was used. Only 57% of nurses reported documenting their oral care. Nurses rated oral care of intubated patients with a priority of 67+/-27.1. Wide variations were noted within and between units in terms of which techniques, equipment, and solutions were used. No significant relationships were found between the use of an evidence-based protocol and demographic and professional characteristics or with the priority given to oral care. While nurses ranked oral care a high priority, many did not implement the latest evidence into their current practice. The level of research utilization was not related to personal or professional characteristics. Therefore attempts should be made to encourage all

Many intensive care unit (ICU) survivors develop psychological problems and cognitive impairment. The relation between sepsis, delirium, and later cognitive problems is not fully elucidated, and the impact of psychological symptoms on cognitive function is poorly studied in ICU survivors. The primary aim of this study was to examine the relationship between sepsis, ICU delirium, and later self-rated cognitive function. A second aim was to investigate the association between psychological problems and self-rated cognitive function 3 months after the ICU stay. Patients staying more than 24 h at the general ICU at the Karolinska University Hospital Solna, Stockholm, Sweden, were screened for delirium with the Confusion Assessment Method-ICU (CAM-ICU) during their ICU stay. Sepsis incidence and severity were recorded. Three months later, 216 patients received the Cognitive Failures Questionnaire (CFQ), Hospital Anxiety and Depression Scale (HADS), and Post-Traumatic Stress Symptoms-10 (PTSS-10) questionnaires via postal mail. One hundred twenty-five patients (60%) responded to all questionnaires. Among respondents, the incidence of severe sepsis or septic shock was 42%. The overall incidence of delirium was 34%. Patients with severe sepsis/septic shock had a higher incidence of delirium, with an odds ratio (OR) of 3.7 (95% confidence interval (CI), 1.7-8.1). Self-rated cognitive problems 3 months post-ICU were found in 58% of the patients. We did not find any association between sepsis or delirium and late self-rated cognitive function. However, there was a correlation between psychological symptoms and self-rated cognitive function, with the strongest correlation between PTSS-10 scores and CFQ scores ( r  = 0.53; p  < 0.001). ICU delirium is more common in severely septic/septic shock patients. In our cohort, neither severe sepsis nor ICU delirium was associated with self-rated cognitive function 3 months after the ICU stay. Ongoing psychological symptoms

Preventing harm remains a persistent challenge in the ICU despite evidence-based practices known to reduce the prevalence of adverse events. This review seeks to describe the critical role of safety culture and patient and family engagement in successful quality improvement initiatives in the ICU. We review the evidence supporting the impact of safety culture and provide practical guidance for those wishing to implement initiatives aimed at improving safety culture and more effectively integrate patients and families in such efforts. Literature review using PubMed including evaluation of key studies assessing large-scale quality improvement efforts in the ICU, impact of safety culture on patient outcomes, methodologies for quality improvement commonly used in healthcare, and patient and family engagement. Print and web-based resources from leading patient safety organizations were also searched. Our group completed a review of original studies, review articles, book chapters, and recommendations from leading patient safety organizations. Our group determined by consensus which resources would best inform this review. A strong safety culture is associated with reduced adverse events, lower mortality rates, and lower costs. Quality improvement efforts have been shown to be more effective and sustainable when paired with a strong safety culture. Different methodologies exist for quality improvement in the ICU; a thoughtful approach to implementation that engages frontline providers and administrative leadership is essential for success. Efforts to substantively include patients and families in the processes of quality improvement work in the ICU should be expanded. Efforts to establish a culture of safety and meaningfully engage patients and families should form the foundation for all safety interventions in the ICU. This review describes an approach that integrates components of several proven quality improvement methodologies to enhance safety culture in the ICU and

The aim of this study was to compare inpatient outcomes and costs for children with respiratory syncytial virus and congenital heart disease before and after the change in management guidelines for respiratory syncytial virus prophylaxis. Hospital discharge data from the Vizient (formerly University HealthSystem Consortium) were queried from October 2012 to June 2014 (Era 1) and July 2014 to April 2016 (Era 2) for patients aged <24 months with an any International Classification of Disease (ICD)-9 or ICD-10 code for congenital heart disease (745-747.49, Q20.0-Q26.4) and a primary or secondary admitting diagnosis of respiratory syncytial virus infection (079.6, J20.5), acute bronchiolitis due to respiratory syncytial virus (466.11, J21.0) or respiratory syncytial virus pneumonia (480.1, J12.1). This study is a review of a national administrative discharge database. Respiratory syncytial virus admissions were identified in 1269 patients aged <24 months with congenital heart disease, with 644 patients in Era 1 and 625 in Era 2. Patients 0-12 months old represented 83% of admissions. Prior to 2014, children aged 0-24 months with congenital heart disease were eligible to receive respiratory syncytial virus prophylaxis. Updated guidelines, published in 2014, restricted the recommendation to administer palivizumab respiratory syncytial virus prophylaxis to children with congenital heart disease only if they are ≤12 months old. The outcome measures are hospital length of stay, ICU admission rate, mortality, and direct costs. There was no change in length of stay, ICU admission rate, in-hospital mortality, or direct costs for children 13-24 months old with congenital heart disease after the change in guidelines. There were no deaths in 13-24 month olds, regardless of era. Our findings provide additional support for the new guideline recommendations to provide respiratory syncytial virus prophylaxis only for children ≤12 months old with congenital heart disease. �

Introduction Anemia among the critically ill has been described in patients with short to medium length of stay (LOS) in the intensive care unit (ICU), but it has not been described in long-stay ICU patients. This study was performed to characterize anemia, transfusion, and phlebotomy practices in patients with prolonged ICU LOS. Methods We conducted a retrospective chart review of consecutive patients admitted to a medical-surgical ICU in a tertiary care university hospital over three years; patients included had a continuous LOS in the ICU of 30 days or longer. Information on transfusion, phlebotomy, and outcomes were collected daily from days 22 to 112 of the ICU stay. Results A total of 155 patients were enrolled. The mean age, admission Acute Physiology and Chronic Health Evaluation II score, and median ICU LOS were 62.3 ± 16.3 years, 23 ± 8, and 49 days (interquartile range 36–70 days), respectively. Mean hemoglobin remained stable at 9.4 ± 1.4 g/dl from day 7 onward. Mean daily phlebotomy volume was 13.3 ± 7.3 ml, and 62% of patients received a mean of 3.4 ± 5.3 units of packed red blood cells at a mean hemoglobin trigger of 7.7 ± 0.9 g/dl after day 21. Transfused patients had significantly greater acuity of illness, phlebotomy volumes, ICU LOS and mortality, and had a lower hemoglobin than did those who were not transfused. Multivariate logistic regression analysis identified the following as independently associated with the likelihood of requiring transfusion in nonbleeding patients: baseline hemoglobin, daily phlebotomy volume, ICU LOS, and erythropoietin therapy (used almost exclusively in dialysis dependent renal failure in this cohort of patients). Small increases in average phlebotomy (3.5 ml/day, 95% confidence interval 2.4–6.8 ml/day) were associated with a doubling in the odds of being transfused after day 21. Conclusion Anemia, phlebotomy, and transfusions, despite low hemoglobin triggers, are common in ICU patients long after admission

This study reanalyzes the data from a study by Leaf, Homel, and Factor (2010) titled "Relationship between ICU Design and Mortality" by adopting and developing objective visibility measures. Various studies attribute healthcare outcomes (patient falls, satisfaction) to a vague notion of patient room visibility. The study by Leaf and colleagues was the first to draw an independent association between patient mortality and patient room visibility, however "visibility" remains imprecise. The original patient dataset was obtained from Dr. Leaf. The 664 patient sample assigned across 12 rooms at the medical ICU at Columbia University Medical Center was reanalyzed in terms of targeted visibility; the unit of analysis was the room, n = 12. Several computer-based visibility measures of patient rooms were used: patient head visibility, patient room visibility, and field of view to nursing station. Patient head visibility was defined as the percentage of area within the central nursing station from which the patient head could be seen; patient room visibility was defined as the percentage of area within the central nursing station that could see the patient room (average value of all patient room grids); field of view was defined as the maximum viewing angle from the patient head to the central nursing station. Among the sickest patients (those with Acute Physiology and Chronic Health Evaluation II > 30), field of view accounted for 33.5% of the variance in ICU mortality, p = 0.049. Subtle differences in patient room visibility may have important effects on clinical outcomes. Case study, critical care/intensive care, methodology, outcomes.

To measure the level of moral distress in PICU and neonatal ICU health practitioners, and to describe the relationship of moral distress with demographic factors, burnout, and uncertainty. Cross-sectional survey. A large pediatric tertiary care center. Neonatal ICU and PICU health practitioners with at least 3 months of ICU experience. A 41-item questionnaire examining moral distress, burnout, and uncertainty. The main outcome was moral distress measured with the Revised Moral Distress Scale. Secondary outcomes were frequency and intensity Revised Moral Distress Scale subscores, burnout measured with the Maslach Burnout Inventory depersonalization subscale, and uncertainty measured with questions adapted from Mishel's Parent Perception of Uncertainty Scale. Linear regression models were used to examine associations between participant characteristics and the measures of moral distress, burnout, and uncertainty. Two-hundred six analyzable surveys were returned. The median Revised Moral Distress Scale score was 96.5 (interquartile range, 69-133), and 58% of respondents reported significant work-related moral distress. Revised Moral Distress Scale items involving end-of-life care and communication scored highest. Moral distress was positively associated with burnout (r = 0.27; p < 0.001) and uncertainty (r = 0.04; p = 0.008) and inversely associated with perceived hospital supportiveness (r = 0.18; p < 0.001). Nurses reported higher moral distress intensity than physicians (Revised Moral Distress Scale intensity subscores: 57.3 vs 44.7; p = 0.002). In nurses only, moral distress was positively associated with increasing years of ICU experience (p = 0.02) and uncertainty about whether their care was of benefit (r = 0.11; p < 0.001) and inversely associated with uncertainty about a child's prognosis (r = 0.03; p = 0.03). In this single-center, cross-sectional study, we found that moral distress is present in PICU and neonatal ICU health practitioners and is correlated

To assess the coping strategies used by family decision makers of adult critical care patients during and after the critical care experience and the relationship of coping strategies to posttraumatic stress symptoms experienced 60 days after hospitalization. A single-group descriptive longitudinal correlational study. Medical, surgical, and neurological ICUs in a large tertiary care university hospital. Consecutive family decision makers of adult critical care patients from August 2012 to November 2013. Study inclusion occurred after the patient's fifth day in the ICU. None. Family decision makers of incapacitated adult ICU patients completed the Brief COPE instrument assessing coping strategy use 5 days after ICU admission and 30 days after hospital discharge or death of the patient and completed the Impact of Event Scale-Revised assessing posttraumatic stress symptoms 60 days after hospital discharge. Seventy-seven family decision makers of the eligible 176 completed all data collection time points of this study. The use of problem-focused (p=0.01) and emotion-focused (p<0.01) coping decreased over time while avoidant coping (p=0.20) use remained stable. Coping strategies 30 days after hospitalization (R2=0.50, p<0.001) were better predictors of later posttraumatic stress symptoms than coping strategies 5 days after ICU admission (R2=0.30, p=0.001) controlling for patient and decision-maker characteristics. The role of decision maker for a parent and patient death were the only noncoping predictors of posttraumatic stress symptoms. Avoidant coping use 30 days after hospitalization mediated the relationship between patient death and later posttraumatic stress symptom severity. Coping strategy use is a significant predictor of posttraumatic stress symptom severity 60 days after hospitalization in family decision makers of ICU patients.

Background Accurate cost estimate and a profit and loss analysis are necessary for health care practice. We performed an actual financial analysis for an intensive care unit (ICU) of a university hospital in Japan, and tried to discuss the health care policy and resource allocation decisions that have an impact on critical intensive care. Methods The costs were estimated by a department level activity based costing method, and the profit and loss analysis was based on a break-even point analysis. The data used included the monthly number of patients, the revenue, and the direct and indirect costs of the ICU in 2003. Results The results of this analysis showed that the total costs of US$ 2,678,052 of the ICU were mainly incurred due to direct costs of 88.8%. On the other hand, the actual annual total patient days in the ICU were 1,549 which resulted in revenues of US$ 2,295,044. However, it was determined that the ICU required at least 1,986 patient days within one fiscal year based on a break-even point analysis. As a result, an annual deficit of US$ 383,008 has occurred in the ICU. Conclusion These methods are useful for determining the profits or losses for the ICU practice, and how to evaluate and to improve it. In this study, the results indicate that most ICUs in Japanese hospitals may not be profitable at the present time. As a result, in order to increase the income to make up for this deficit, an increase of 437 patient days in the ICU in one fiscal year is needed, and the number of patients admitted to the ICU should thus be increased without increasing the number of beds or staff members. Increasing the number of patients referred from cooperating hospitals and clinics therefore appears to be the best strategy for achieving these goals. PMID:16403235

Over the recent period, the use of induced hypothermia has gained an increasing interest for critically ill patients, in particular in brain-injured patients. The term "targeted temperature management" (TTM) has now emerged as the most appropriate when referring to interventions used to reach and maintain a specific level temperature for each individual. TTM may be used to prevent fever, to maintain normothermia, or to lower core temperature. This treatment is widely used in intensive care units, mostly as a primary neuroprotective method. Indications are, however, associated with variable levels of evidence based on inhomogeneous or even contradictory literature. Our aim was to conduct a systematic analysis of the published data in order to provide guidelines. We present herein recommendations for the use of TTM in adult and paediatric critically ill patients developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. These guidelines were conducted by a group of experts from the French Intensive Care Society (Société de Réanimation de Langue Française [SRLF]) and the French Society of Anesthesia and Intensive Care Medicine (Société Francaise d'Anesthésie Réanimation [SFAR]) with the participation of the French Emergency Medicine Association (Société Française de Médecine d'Urgence [SFMU]), the French Group for Pediatric Intensive Care and Emergencies (Groupe Francophone de Réanimation et Urgences Pédiatriques [GFRUP]), the French National Association of Neuro-Anesthesiology and Critical Care (Association Nationale de Neuro-Anesthésie Réanimation Française [ANARLF]), and the French Neurovascular Society (Société Française Neurovasculaire [SFNV]). Fifteen experts and two coordinators agreed to consider questions concerning TTM and its practical implementation in five clinical situations: cardiac arrest, traumatic brain injury, stroke, other brain injuries, and shock. This resulted in 30 recommendations

To estimate the potential ICU-related cost savings if in-hospital advance care planning and ICU-based palliative care consultation became standard of care for patients with chronic and serious illness. Decision analysis using literature estimates and inpatient administrative data from Premier. Patients with chronic, life-limiting illness admitted to a hospital within the Premier network. None. Using Premier data (2008-2012), ICU resource utilization and costs were tracked over a 1-year time horizon for 2,097,563 patients with chronic life-limiting illness. Using a Markov microsimulation model, we explored the potential cost savings from the hospital system perspective under a variety of scenarios by varying the interventions' efficacies and availabilities. Of 2,097,563 patients, 657,825 (31%) used the ICU during the 1-year time horizon; mean ICU spending per patient was 11.3k (SD, 17.6k). In the base-case analysis, if in-hospital advance care planning and ICU-based palliative care consultation were systematically provided, we estimated a mean reduction in ICU costs of 2.8k (SD, 14.5k) per patient and an ICU cost saving of 25%. Among the simulated patients who used the ICU, the receipt of both interventions could have resulted in ICU cost savings of 1.9 billion, representing a 6% reduction in total hospital costs for these patients. In-hospital advance care planning and palliative care consultation have the potential to result in significant cost savings. Studies are needed to confirm these findings, but our results provide guidance for hospitals and policymakers.

Whether the presence of Candida spp. in lower respiratory tract (LRT) secretions is a marker of underlying disease, intensive care unit (ICU) treatment and antibiotic therapy or contributes to poor clinical outcome is unclear. We investigated healthy controls, patients with proposed risk factors for Candida growth in LRT (antibiotic therapy, ICU treatment with and without antibiotic therapy), ICU patients with pneumonia and antibiotic therapy and candidemic patients (for comparison of truly invasive and colonizing Candida spp.). Fungal patterns were determined by conventional culture based microbiology combined with molecular approaches (next generation sequencing, multilocus sequence typing) for description of fungal and concommitant bacterial microbiota in LRT, and host and fungal biomarkes were investigated. Admission to and treatment on ICUs shifted LRT fungal microbiota to Candida spp. dominated fungal profiles but antibiotic therapy did not. Compared to controls, Candida was part of fungal microbiota in LRT of ICU patients without pneumonia with and without antibiotic therapy (63% and 50% of total fungal genera) and of ICU patients with pneumonia with antibiotic therapy (73%) (p<0.05). No case of invasive candidiasis originating from Candida in the LRT was detected. There was no common bacterial microbiota profile associated or dissociated with Candida spp. in LRT. Colonizing and invasive Candida strains (from candidemic patients) did not match to certain clades withdrawing the presence of a particular pathogenic and invasive clade. The presence of Candida spp. in the LRT rather reflected rapidly occurring LRT dysbiosis driven by ICU related factors than was associated with invasive candidiasis. PMID:27206014

Background Advanced predictive analytical techniques are being increasingly applied to clinical risk assessment. This study compared a neural network model to several other models in predicting the length of stay (LOS) in the cardiac surgical intensive care unit (ICU) based on pre-incision patient characteristics. Methods Thirty six variables collected from 185 cardiac surgical patients were analyzed for contribution to ICU LOS. The Automatic Linear Modeling (ALM) module of IBM-SPSS software identified 8 factors with statistically significant associations with ICU LOS; these factors were also analyzed with the Artificial Neural Network (ANN) module of the same software. The weighted contributions of each factor (“trained” data) were then applied to data for a “new” patient to predict ICU LOS for that individual. Results Factors identified in the ALM model were: use of an intra-aortic balloon pump; O2 delivery index; age; use of positive cardiac inotropic agents; hematocrit; serum creatinine ≥ 1.3 mg/deciliter; gender; arterial pCO2. The r2 value for ALM prediction of ICU LOS in the initial (training) model was 0.356, p <0.0001. Cross validation in prediction of a “new” patient yielded r2 = 0.200, p <0.0001. The same 8 factors analyzed with ANN yielded a training prediction r2 of 0.535 (p <0.0001) and a cross validation prediction r2 of 0.410, p <0.0001. Two additional predictive algorithms were studied, but they had lower prediction accuracies. Our validated neural network model identified the upper quartile of ICU LOS with an odds ratio of 9.8(p <0.0001). Conclusions ANN demonstrated a 2-fold greater accuracy than ALM in prediction of observed ICU LOS. This greater accuracy would be presumed to result from the capacity of ANN to capture nonlinear effects and higher order interactions. Predictive modeling may be of value in early anticipation of risks of post-operative morbidity and utilization of ICU facilities. PMID:26710254

Intensive care unit (ICU) patients are at risk of in-ICU morbidities and mortality, making specific systems for identifying at-risk patients a necessity for improving clinical care. This study presents a new method for predicting in-hospital mortality using heart rate variability (HRV) collected from the times of a patient's ICU stay. In this paper, a HRV time series processing based method is proposed for mortality prediction of ICU cardiovascular patients. HRV signals were obtained measuring R-R time intervals. A novel method, named return map, is then developed that reveals useful information from the HRV time series. This study also proposed several features that can be extracted from the return map, including the angle between two vectors, the area of triangles formed by successive points, shortest distance to 45° line and their various combinations. Finally, a thresholding technique is proposed to extract the risk period and to predict mortality. The data used to evaluate the proposed algorithm obtained from 80 cardiovascular ICU patients, from the first 48 h of the first ICU stay of 40 males and 40 females. This study showed that the angle feature has on average a sensitivity of 87.5% (with 12 false alarms), the area feature has on average a sensitivity of 89.58% (with 10 false alarms), the shortest distance feature has on average a sensitivity of 85.42% (with 14 false alarms) and, finally, the combined feature has on average a sensitivity of 92.71% (with seven false alarms). The results showed that the last half an hour before the patient's death is very informative for diagnosing the patient's condition and to save his/her life. These results confirm that it is possible to predict mortality based on the features introduced in this paper, relying on the variations of the HRV dynamic characteristics.

This study aimed to provide a new global and comprehensive evaluation of recent ICU ventilators taking into account both technical performances and ergonomics. Six recent ICU ventilators were evaluated. Technical performances were assessed under two FIO 2 levels (100%, 50%), three respiratory mechanics combinations (Normal: compliance [C] = 70 mL cmH 2 O -1 /resistance [R] = 5 cmH 2 O L -1  s -1 ; Restrictive: C = 30/R = 10; Obstructive: C = 120/R = 20), four exponential levels of leaks (from 0 to 12.5 L min -1 ) and three levels of inspiratory effort (P0.1 = 2, 4 and 8 cmH 2 O), using an automated test lung. Ergonomics were evaluated by 20 ICU physicians using a global and comprehensive model involving physiological response to stress measurements (heart rate, respiratory rate, tidal volume variability and eye tracking), psycho-cognitive scales (SUS and NASA-TLX) and objective tasks completion. Few differences in terms of technical performance were observed between devices. Non-invasive ventilation modes had a huge influence on asynchrony occurrence. Using our global model, either objective tasks completion, psycho-cognitive scales and/or physiological measurements were able to depict significant differences in terms of devices' usability. The level of failure that was observed with some devices depicted the lack of adaptation of device's development to end users' requests. Despite similar technical performance, some ICU ventilators exhibit low ergonomics performance and a high risk of misusage.

We then focus on the measurement of ICU nurses' workload using a subjective rating instrument: the NASA TLX.We conducted secondary data analysis on data from two, multi-side, cross-sectional questionnaire studies to examine several instruments to measure ICU nurses' workload. The combined database contains the data from 757 ICU nurses in 8 hospitals and 21 ICUs.Results show that the different methods to measure workload of ICU nurses, such as patient-based and operator-based workload, are only moderately correlated, or not correlated at all. Results show further that among the operator-based instruments, the NASA TLX is the most reliable and valid questionnaire to measure workload and that NASA TLX can be used in a healthcare setting. Managers of hospitals and ICUs can benefit from the results of this research as it provides benchmark data on workload experienced by nurses in a variety of ICUs.

 Delayed antifungal therapy for invasive candidiasis (IC) contributes to poor outcomes. Predictive risk models may allow targeted antifungal prophylaxis to those at greatest risk.  A prospective cohort study of 6685 consecutive nonneutropenic patients admitted to 7 Australian intensive care units (ICUs) for ≥72 hours was performed. Clinical risk factors for IC occurring prior to and following ICU admission, colonization with Candida species on surveillance cultures from 3 sites assessed twice weekly, and the occurrence of IC ≥72 hours following ICU admission or ≤72 hours following ICU discharge were measured. From these parameters, a risk-predictive model for the development of ICU-acquired IC was then derived.  Ninety-six patients (1.43%) developed ICU-acquired IC. A simple summation risk-predictive model using the 10 independently significant variables associated with IC demonstrated overall moderate accuracy (area under the receiver operating characteristic curve = 0.82). No single threshold score could categorize patients into clinically useful high- and low-risk groups. However, using 2 threshold scores, 3 patient cohorts could be identified: those at high risk (score ≥6, 4.8% of total cohort, positive predictive value [PPV] 11.7%), those at low risk (score ≤2, 43.1% of total cohort, PPV 0.24%), and those at intermediate risk (score 3-5, 52.1% of total cohort, PPV 1.46%).  Dichotomization of ICU patients into high- and low-risk groups for IC risk is problematic. Categorizing patients into high-, intermediate-, and low-risk groups may more efficiently target early antifungal strategies and utilization of newer diagnostic tests. © The Author 2016.

Emergency manuals, which are safety essentials in non-medical high-reliability organizations (e.g., aviation), have recently gained acceptance in critical medical environments. Of the existing emergency manuals in anesthesiology, most are geared towards intraoperative settings. Additionally, most evidence supporting their efficacy focuses on the study of physicians with at least some meaningful experience as a physician. Our aim was to evaluate whether an emergency manual would improve the performance of novice physicians (post-graduate year [PGY] 1 or first year resident) in managing a critical event in the intensive care unit (ICU). PGY1 interns (n=41) were assessed on the management of a simulated critical event (unstable bradycardia) in the ICU. Participants underwent a group allocation process to either a control group (n=18) or an intervention group (emergency manual provided, n=23). The number of successfully executed treatment and diagnostic interventions completed was evaluated over a ten minute (600 seconds) simulation for each participant. The participants using the emergency manual averaged 9.9/12 (83%) interventions, compared to an average of 7.1/12 (59%) interventions (p < 0.01) in the control group. The use of an emergency manual was associated with a significant improvement in critical event management by individual novice physicians in a simulated ICU patient (23% average increase).

Objective The purpose of this study was to evaluate ICU nurses’ ability to detect patient change using an integrated graphical information display (IGID) versus a conventional tabular ICU patient information display (i.e. electronic chart). Design Using participants from two different sites, we conducted a repeated measures simulator-based experiment to assess ICU nurses’ ability to detect abnormal patient variables using a novel IGID versus a conventional tabular information display. Patient scenarios and display presentations were fully counterbalanced. Measurements We measured percent correct detection of abnormal patient variables, nurses’ perceived workload (NASA-TLX), and display usability ratings. Results 32 ICU nurses (87% female, median age of 29 years, and median ICU experience of 2.5 years) using the IGID detected more abnormal variables compared to the tabular display [F (1,119)=13.0, p < 0.05]. There was a significant main effect of site [F (1, 119)=14.2], with development site participants doing better. There were no significant differences in nurses’ perceived workload. The IGID display was rated as more usable than the conventional display, [F (1, 60)=31.7]. Conclusion Overall, nurses reported more important physiological information with the novel IGID than tabular display. Moreover, the finding of site differences may reflect local influences in work practice and involvement in iterative display design methodology. Information displays developed using user-centered design should accommodate the full diversity of the intended user population across use sites. PMID:22534099

Robotic tele-presence (RTP) is a form of mobile telemedicine, which enables a direct face-to-face rapid response by the physician, instead of the traditional telephonic paradigm. We hypothesized that a model of RTP for after-hour ICU rounds and emergencies would be associated with improved ICU nurse satisfaction. We implemented a prospective nighttime multidisciplinary ICU round time, using RTP at our neuro-ICU. To test for critical ICU nurse team satisfaction, a questionnaire was implemented. The primary outcome was nurse satisfaction measured through a questionnaire with answers trichotomized into: agreement, disagreement, and no opinion. The occurrence of outcomes was compared between the groups by χ2 or Fisher exact tests for the difference in proportions (PD) with Bonferroni correction for multiple pairwise comparisons. In total, 34 nurses completed the pre-survey and 40 nurses completed the post-survey. Night nurses were more likely to agree that RTP was associated with: ICU physicians being sufficiently available in the ICU (agreement 6-20%, PD 14%, p = 0.008), present during acute emergencies (agreement 44-65%, PD 21%, p = 0.007), and had enough time to get questions answered from the physician team (agreement 41-53%, PD 11%, p = NS). This data suggest improvement in critical care nursing team satisfaction with a model of RTP in the neuroscience ICU, particularly during nighttime hours. RTP is a tool that may enhance communication among components of the ICU team.

Prevalence of iron deficiency (ID) at intensive care (ICU) admission is around 25 to 40%. Blood losses are important during ICU stay, leading to iron losses, but prevalence of ID at ICU discharge is unknown. ID has been associated with fatigue and muscular weakness, and may thus impair post-ICU rehabilitation. This study assessed ID prevalence at ICU discharge, day 28 (D28) and six months (M6) after and its relation with fatigue. We conducted this prospective, multicenter observational study at four University hospitals ICUs. Anemic (hemoglobin (Hb) less than 13 g/dL in male and less than 12 g/dL in female) critically ill adult patients hospitalized for at least five days had an iron profile taken at discharge, D28 and M6. ID was defined as ferritin less than 100 ng/L or less than 300 ng/L together with a transferrin saturation less than 20%. Fatigue was assessed by numerical scale and the Multidimensional Fatigue Inventory-20 questionnaire at D28 and M6 and muscular weakness by a hand grip test at ICU discharge. Among 107 patients (men 77%, median (IQR) age 63 (48 to 73) years) who had a complete iron profile at ICU discharge, 9 (8.4%) had ID. At ICU discharge, their hemoglobin concentration (9.5 (87.7 to 10.3) versus 10.2 (92.2 to 11.7) g/dL, P =0.09), hand grip strength (52.5 (30 to 65) versus 49.5 (15.5 to 67.7)% of normal value, P =0.61) and visual analog scale fatigue scale (57 (40 to 80) versus 60 (47.5 to 80)/100, P =0.82) were not different from non-ID patients. At D28 (n =80 patients) and M6 (n =78 patients), ID prevalence increased (to 25 and 35% respectively) while anemia prevalence decreased (from 100% to 80 and 25% respectively, P <0.0001). ID was associated with increased fatigue at D28, after adjustment for main confounding factors, including anemia (regression coefficient (95%CI), 3.19 (0.74 to 5.64), P =0.012). At M6, this association disappeared. The prevalence of ID increases from 8% at discharge to 35% six months after prolonged ICU stay (more

The relationship between tiredness and the risk of medical errors is now commonly accepted. The main objective of this study was to assess the impact of an intensive care unit (ICU) night shift on the cognitive performance of a group of intensivists. The influence of professional experience and the amount of sleep on cognitive performance was also investigated. A total of 51 intensivists from three ICUs (24 seniors and 27 residents) were included. The study participants were evaluated after a night of rest and after a night shift according to a randomized order. Four cognitive skills were tested according to the Wechsler Adult Intelligence Scale and the Wisconsin Card Sorting Test. All cognitive abilities worsened after a night shift: working memory capacity (11.3 ± 0.3 vs. 9.4 ± 0.3; p < 0.001), speed of processing information (13.5 ± 0.4 vs. 10.9 ± 0.3; p < 0.001), perceptual reasoning (10.6 ± 0.3 vs. 9.3 ± 0.3; p < 0.002), and cognitive flexibility (41.2 ± 1.2 vs. 44.2 ± 1.3; p = 0.063). There was no significant difference in terms of level of cognitive impairment between the residents and ICU physicians. Only cognitive flexibility appeared to be restored after 2 h of sleep. The other three cognitive skills were altered, regardless of the amount of sleep during the night shift. The cognitive abilities of intensivists were significantly altered following a night shift in the ICU, regardless of either the amount of professional experience or the duration of sleep during the shift. The consequences for patients' safety and physicians' health should be further evaluated.

Background Understanding intensive care unit (ICU) triage decisions for high-risk surgical patients may ultimately facilitate resource allocation and improve outcomes. The surgical Apgar score (SAS) is a simple score that uses intraoperative information on hemodynamics and blood loss to predict postoperative morbidity and mortality, with lower scores associated with worse outcomes. We hypothesized that the SAS would be associated with the decision to admit a patient to the ICU postoperatively. Methods Retrospective cohort study of adults undergoing major intra-abdominal surgery from 2003 to 2010 at an academic medical center. We calculated the SAS (0 – 10) for each patient based on intraoperative heart rate, mean arterial pressure, and estimated blood loss. Using logistic regression, we assessed the association of the SAS with the decision to admit a patient directly to the ICU after surgery. Results The cohort consisted of 8,501 patients, with 72.7% having a SAS of 7-10 and less than 5% a SAS of 0-4. A total of 8.7% of patients were transferred immediately to the ICU postoperatively. After multivariate adjustment, there was a strong association between the SAS and the decision to admit a patient to the ICU (adjusted odds ratio 14.41 [95% CI 6.88 – 30.19, P < 0.001] for SAS 0-2, 4.42 [95% CI 3.19 – 6.13, P <0.001] for SAS 3-4, and 2.60 [95% CI 2.08 – 3.24, P < 0.001] for SAS 5-6 compared with SAS 7-8). Conclusions The SAS is strongly associated with clinical decisions regarding immediate ICU admission after high-risk intra-abdominal surgery. These results provide an initial step towards understanding whether intraoperative hemodynamics and blood loss influence ICU triage for post-surgical patients. PMID:23744956

An assessment of changes in health-care professional behavior as a result of the introduction of a PACS (picture archiving and communication system) display station to an adult medical- surgical intensive care unit (ICU) is investigated via pre- and post-PACs evaluations. ICU display station utilization and the impact on clinical operations are also examined. Parameters measured both pre- and post-PACS ICU display station placement include the number of films per patient day, the number of clinician reviews of a patient's images per day and the percentage of images on which the unit interacts with a radiologist. The elapsed times from the time of exposure to the time of: review by the referring physician, radiologist-unit interaction and clinical action based on image information are also measured. The results of this investigation suggest that the introduction of a PaCS display station in the ICU may reduce the number of exams per patient day, decrease the elapsed time from the time of exposure to the time of review by the unit clinician, and improve the time to clinical action. Note, however, that it does not appear to change the percentage of total images on which the unit interacts with a radiologist.

The aim of this study was to determine if severity assessment tools (general severity of illness and community-acquired pneumonia specific scores) can be used to guide decisions for patients admitted to the intensive care unit (ICU) due to pandemic influenza A pneumonia. A prospective, observational, multicentre study included 265 patients with a mean age of 42 (±16.1) years and an ICU mortality of 31.7%. On admission to the ICU, the mean pneumonia severity index (PSI) score was 103.2 ± 43.2 points, the CURB-65 score was 1.7 ± 1.1 points and the PIRO-CAP score was 3.2 ± 1.5 points. None of the scores had a good predictive ability: area under the ROC for PSI, 0.72 (95% CI, 0.65-0.78); CURB-65, 0.67 (95% CI, 0.59-0.74); and PIRO-CAP, 0.64 (95% CI, 0.56-0.71). The PSI score (OR, 1.022 (1.009-1.034), p 0.001) was independently associated with ICU mortality; however, none of the three scores, when used at ICU admission, were able to reliably detect a low-risk group of patients. Low risk for mortality was identified in 27.5% of patients using PIRO-CAP, but above 40% when using PSI (I-III) or CURB65 (<2). Observed mortality was 13.7%, 13.5% and 19.4%, respectively. Pneumonia-specific scores undervalued severity and should not be used as instruments to guide decisions in the ICU. © 2011 The Authors.

To describe the characteristics and management of severe trauma disease in Spanish Intensive Care Units (ICUs). Registry of trauma in the ICU (RETRAUCI). Pilot phase. A prospective, multicenter registry. Thirteen Spanish ICUs. Patients with trauma disease admitted to the ICU. None. Epidemiology, out-of-hospital attention, registry of injuries, resources utilization, complications and outcome were evaluated. Patients, n=2242. Mean age 47.1±19.02 years. Males 79%. Blunt trauma 93.9%. Injury Severity Score 22.2±12.1, Revised Trauma Score 6.7±1.6. Non-intentional in 84.4% of the cases. The most common causes of trauma were traffic accidents followed by pedestrian and high-energy falls. Up to 12.4% were taking antiplatelet medication or anticoagulants. Almost 28% had a suspected or confirmed toxic influence in trauma. Up to 31.5% required an out-of-hospital artificial airway. The time from trauma to ICU admission was 4.7±5.3hours. At ICU admission, 68.5% were hemodynamically stable. Brain and chest injuries predominated. A large number of complications were documented. Mechanical ventilation was used in 69.5% of the patients (mean 8.2±9.9 days), of which 24.9% finally required a tracheostomy. The median duration of stay in the ICU and in hospital was 5 (range 3-13) and 9 (5-19) days, respectively. The ICU mortality rate was 12.3%, while the in-hospital mortality rate was 16.0%. The pilot phase of the RETRAUCI offers a first impression of the epidemiology and management of trauma disease in Spanish ICUs. Copyright © 2015 Elsevier España, S.L.U. y SEMICYUC.

To evaluate the association between cumulative dose of haloperidol and next-day diagnosis of delirium in a cohort of older medical ICU patients, with adjustment for its time-dependent confounding with fentanyl and intubation. Prospective, observational study. Medical ICU at an urban, academic medical center. Age 60 years and older admitted to the medical ICU who received at least one dose of haloperidol (n = 93). Of these, 72 patients were intubated at some point in their medical ICU stay, whereas 21 were never intubated. None. Detailed data were collected concerning time, dosage, route of administration of all medications, as well as for important clinical covariates, and daily status of intubation and delirium using the confusion assessment method for the ICU and a chart-based algorithm. Among nonintubated patients, and after adjustment for time-dependent confounding and important covariates, each additional cumulative milligram of haloperidol was associated with 5% higher odds of next-day delirium with odds ratio of 1.05 (credible interval [CI], 1.02-1.09). After adjustment for time-dependent confounding and covariates, intubation was associated with a five-fold increase in odds of next-day delirium with odds ratio of 5.66 (CI, 2.70-12.02). Cumulative dose of haloperidol among intubated patients did not change their already high likelihood of next-day delirium. After adjustment for time-dependent confounding, the positive associations between indicators of intubation and of cognitive impairment and next-day delirium became stronger. These results emphasize the need for more studies regarding the efficacy of haloperidol for treatment of delirium among older medical ICU patients and demonstrate the value of assessing nonintubated patients.

Teamwork and team training in the ICU: where do the similarities with aviation end?

2011-01-01

The aviation industry has made significant progress in identifying the skills and behaviors that result in effective teamwork. Its conceptualization of teamwork, development of training programs, and design of assessment tools are highly relevant to the intensive care unit (ICU). Team skills are important for maintaining safety in both domains, as multidisciplinary teams must work effectively under highly complex, stressful, and uncertain conditions. However, there are substantial differences in the nature of work and structure of teams in the ICU in comparison with those in aviation. While intensive care medicine may wish to use the advances made by the aviation industry for conceptualizing team skills and implementing team training programs, interventions must be tailored to the highly specific demands of the ICU.

To determine whether extension to holidays and weekends of the protocol for the early proactive detection of severity in hospital ("ICU without walls" project) results in decreased mortality among patients admitted to the ICU during those days. A quasi-experimental before-after study was carried out. A level 2 hospital with 210 beds and a polyvalent ICU with 8 beds. The control group involved no "ICU without walls" activity on holidays or weekends and included those patients admitted to the ICU on those days between 1 January 2010 and 30 April 2013. The intervention group in turn extended the "ICU without walls" activity to holidays and weekends, and included those patients admitted on those days between 1 May 2013 and 31 October 2014. Patients arriving from the operating room after scheduled surgery were excluded. An analysis was made of the demographic variables (age, gender), origin (emergency room, hospital ward, operating room), type of patient (medical, surgical), reason for admission, comorbidities and SAPS 3 score as a measure of severity upon admission, stay in the ICU and in hospital, and mortality in the ICU and in hospital. A total of 389 and 161 patients were included in the control group and intervention group, respectively. There were no differences between the 2 groups except as regards cardiovascular comorbidity (49% in the control group versus 33% in the intervention group; P<.001), severity upon admission (median SAPS 3 score 52 [percentiles 25-75: 42-63) in the control group versus 48 [percentiles 25-75: 40-56] in the intervention group; P=.008) and mortality in the ICU (11% in the control group [95% CI 8-14] versus 3% [95% CI 1-7] in the intervention group; P=.003). In the multivariate analysis, the only 2 factors associated to mortality in the ICU were the SAPS 3 score (OR 1.08; 95% CI 1.06-1.11) and inclusion in the intervention group (OR 0.33; 95% CI 0.12-0.89).

Objective Spiritual distress is common in the ICU, and spiritual care providers are often called upon to provide care for patients and their families. Our goal was to evaluate the activities spiritual care providers’ conduct to support patients and families, and whether those activities are associated with family satisfaction with ICU care. Design Prospective cohort study. Setting 350-bed, 65-ICU bed tertiary care teaching hospital. Subjects Spiritual care providers and family members of patients who died in the ICU or within 30 hours of transfer from the ICU. Measurements Spiritual care providers completed surveys reporting their activities. Family members completed validated measures of satisfaction with care and satisfaction with spiritual care. Clustered regression was used to assess the association between activities completed by spiritual care providers and family ratings of care. Results Of 494 eligible patients, 275 family members completed surveys (response rate, 56%). Fifty-seven spiritual care providers received surveys relating to 268 patients, completing 285 surveys for 244 patients (response rate, 91%). Spiritual care providers commonly reported activities related to supporting religious and spiritual needs (>=90%) and providing support for family feelings (90%). Discussions about the patient’s wishes for end-of-life care and a greater number of spiritual care activities performed were both associated with increased overall family satisfaction with ICU care (p<0.05). Discussions about a patient’s end-of-life wishes, preparation for a family conference, and total number of activities performed were associated with improved family satisfaction with decision-making in the ICU (p<0.05). Conclusions Spiritual care providers engage in a variety of activities with families of ICU patients; several are associated with increased family satisfaction with ICU care in general and decision-making in the ICU specifically. These findings provide insight into

Parenteral nutrition in the ICU setting: need for a shift in utilization.

PubMed

Oshima, Taku; Hiesmayr, Michael; Pichard, Claude

2016-03-01

The difficulties to feed the patients adequately with enteral nutrition alone have drawn the attention of the clinicians toward the use of parenteral nutrition, although recommendations by the recent guidelines are conflicting. This review focuses on the intrinsic role of parenteral nutrition, its new indication, and modalities of use for the critically ill patients. A recent trial demonstrated that selecting either parenteral nutrition or enteral nutrition for early nutrition has no impact on clinical outcomes. However, it must be acknowledged that the risk of relative overfeeding is greater when using parenteral nutrition and the risk of underfeeding is greater when using enteral nutrition because of gastrointestinal intolerance. Both overfeeding and underfeeding in the critically ill patients are associated with deleterious outcomes. Thus, early and adequate feeding according to the specific energy needs can be recommended as the optimal feeding strategy. Parenteral nutrition can be used to substitute or supplement enteral nutrition, if adequately prescribed. Testing for enteral nutrition tolerance during 2-3 days after ICU admission provides the perfect timing to start parenteral nutrition, if needed. In case of absolute contraindication for enteral nutrition, consider starting parenteral nutrition carefully to avoid overfeeding.

(1) To assess Jordanian ICU patients' pain characteristics (intensity and interference) and levels of pain management satisfaction; and (2) to determine potential predictors of pain management satisfaction among ICU patients. A descriptive cross-sectional design was utilised using the American Pain Society-Patient Outcome Questionnaire to survey 139 Jordanian ICU patients from different health care sectors in Jordan. High levels of pain and pain interferences were reported by participants, which were higher than those reported by previous studies in other countries. However, participants were relatively satisfied with pain management approaches. Also, the results showed a predictive model of three potential predictors, which accounted for 36% of the variance in participants' satisfaction with pain management (adjusted R(2)=0.36, F=12.14, df=7129, p<0.005). The strongest predictor to participants' satisfaction with pain management was time needed to get analgesia (beta=-0.480, p<0.001), followed by average pain interference (beta=0.218, p=0.02), and being told about importance of reporting pain (beta=0.198, p=0.006). Jordanian ICU patients reported high pain levels, which supports the need for applying a caring attitude in managing patients' pain reports. Also, such a study is among the first pain management studies in Jordan aiming at setting the stage for future research studies. Finally, results can be included in planning pain management strategies and protocols within hospitals. Copyright © 2014 Australian College of Critical Care Nurses Ltd. Published by Elsevier Ltd.

2014-01-01

The incidence of sepsis continues to increase. However, over the past decade marked reductions in sepsis-related in-hospital mortality have been reported. Large variations in the presentation and severity of illness may be encountered in ICU patients with severe sepsis, which might preclude the success of screening and guideline programmes. However, the authors of this article were able to prove that a national programme involving screening and a package of interventions did lower relative in-hospital mortality by 16.7% over 3.5 years in 52 participating hospitals in the Netherlands. In-hospital mortality did not change in 30 non-participating hospitals. Therefore, the authors recommend implementing updated guidelines, sepsis quality indicators and programmes with a package of interventions to further reduce sepsis mortality. Furthermore, additional research on long term consequences in sepsis survivors is warranted.

Family members provide essential support for ICU patients, contributing to their mental and physical recovery. Empowering ICU patients' families may help them overcome inadequacies and meet their own and patients' acknowledged needs. Nursing should understand and address patients' families' empowerment status. To develop a tool, the Nurses' Empowerment Scale for Intensive Care Unit (ICU) Patients' Families (NESIPF), to help ICU nursing staff assess the empowerment status of patients' families. Four-phase instrument development study. A 19-item instrument was initially generated based on literature review and interviews with family members of ICU patients. The Delphi research method was applied to gain expert opinion and consensus via rounds of questionnaires. A panel of 27 experts experienced in critical care medicine, nursing and psychology participated in two Delphi rounds and their input helped formulate an 18-item pretest instrument. Families of 20 patients were recruited to examine instrument readability. After a 2-week interval, another 20 patients' families were recruited to examine test-retest reliability. Two hundred questionnaires were then administered and analysed to examine the instrument's construct validity, criterion-related validity and internal consistency. Expert authority coefficients of two Delphi rounds reached 0·89 and 0·91. Kendall' W coefficients of 0·113 (P < 0·001) in round 1 and 0·220 (P < 0·001) in round 2 indicated slight to fair agreement among experts. Content validity index (CVI) reached 1·0 for 12 items; the CVI for item 13 was <0·7 so it was excluded. Cronbach's α coefficient was 0·92, indicating acceptable internal consistency reliability. The coefficient of internal consistency of each dimension was 0·717-0·921. The Pearson correlation coefficient >0·9 (P < 0·05) showed an acceptable test-retest reliability. The instrument has acceptable reliability and validity and can assess the empowerment status of families of

Monitoring costs in the ICU: a search for a pertinent methodology.

Reis Miranda, D; Jegers, M

2012-10-01

Attempts to determine costs in the intensive care unit (ICU) were not successful until now, as they failed to detect differences of costs between patients. The methodology and/or the instruments used might be at the origin of this failure. Based on the results of the European ICUs studies and on the descriptions of the activities of care in the ICU, we gathered and analysed the relevant literature concerning the monitoring of costs in the ICU. The aim was to formulate a methodology, from an economic perspective, in which future research may be framed. A bottom-up microcosting methodology will enable to distinguish costs between patients. The resulting information will at the same time support the decision-making of top management and be ready to include in the financial system of the hospital. Nursing staff explains about 30% of the total costs. This relation remains constant irrespective of the annual nurse/patient ratio. In contrast with other scoring instruments, the nursing activities score (NAS) covers all nursing activities. (1) NAS is to be chosen for quantifying nursing activities; (2) an instrument for measuring the physician's activities is not yet available; (3) because the nursing activities have a large impact on total costs, the standardisation of the processes of care (following the system approach) will contribute to manage costs, making also reproducible the issue of quality of care; (4) the quantification of the nursing activities may be the required (proxy) input for the automated bottom-up monitoring of costs in the ICU. © 2012 The Authors.

To compare the validity of the Multiple Organ Dysfunction Score (MODS), Sequential Organ Failure Assessment (SOFA), and Logistic Organ Dysfunction Score (LOD) for predicting ICU mortality of Thai critically ill patients. A retrospective study was made of prospective data collected between the 1st July 2004 and 31st March 2006 at Songklanagarind Hospital. One thousand seven hundred and eighty two patients were enrolled in the present study. Two hundred and ninety three (16.4%) deaths were recorded in the ICU. The areas under the Receiver Operating Curves (A UC) for the prediction of ICU mortality the results were 0.861 for MODS, 0.879 for SOFA and 0.880 for LOD. The AUC of SOFA and LOD showed a statistical significance higher than the MODS score (p = 0.014 and p = 0.042, respectively). Of all the models, the neurological failure score showed the best correlation with ICU mortality. All three organ dysfunction scores satisfactorily predicted ICU mortality. The LOD and neurological failure had the best correlation with ICU outcome.

The aim of the present study was to investigate the current trends of using antimicrobial drugs in the ICU at a tertiary level teaching hospital in Mymensingh. The study of prescribing patterns seeks to monitor, evaluate and suggest modifications in clinicians prescribing habits so as to make medical care rational. It was an observational type of descriptive study, conducted in the Mymensingh medical college hospital, Mymensingh, during the study period of June 2016 to September 2016.The study was approved by the institutional ethical committee. Most patients in the ICU belonged to the older age group >60 years. Male patients were more than the female patients in ICU. Average duration of stay in ICU was 4.35 days. Admissions in ICU were common due to respiratory system related diseases and the present study showed that 31.68% of the reported cases belong to the respiratory system. Average number of drugs per prescription was 6.46. Average number of anti-microbial drugs per prescription was 1.38. Cephalosporin group and individually ceftriaxone was the most frequently prescribed antimicrobial group and agent respectively in the ICU. Most commonly used antimicrobial combination was Cephalosporin and Metronidazole (43.33%) followed by Carbapenem (Meropenem) and Metronidazole (13.33%). Most antimicrobial agents were prescribed without bacteriological culture and sensivity testing evidence. There is a need for motivating the physicians to prescribe antimicrobial agents with supportive bacteriological evidences.

A urinary tract infection (UTI) disease state management guideline, including risk-based antimicrobial recommendations, Foley catheter management and transitions of care, was implemented. This study evaluated the outcomes associated with implementation of the guideline. A retrospective study was conducted between 1 July 2013 and 30 September 2013 (pre-implementation) and between 1 July 2014 and 30 September 2014 (post-implementation). Symptomatic patients treated for UTI within 24 h with an identified pathogen were included. Risk-based patient groups were community-acquired UTI, healthcare-associated UTI, or extended-spectrum β-lactamase (ESBL) history in prior 12 months. Recommended antimicrobials were ceftriaxone, cefepime ± vancomycin, or doripenem ± vancomycin, respectively. Given the low post-implementation guideline adherence, pre- and post-groups were combined to evaluate potential guideline value. Length of stay (LOS) decreased when guidelines were followed [5 (IQR 4-7) days vs. 6 (IQR 4-8) days; P = 0.03] or appropriate therapy (according to in vitro susceptibilities) was given [5 (IQR 4-7) days vs. 6 (IQR 4-9) days; P = 0.03]. Those receiving guideline-recommended antimicrobials were more likely to have appropriate therapy within 24 h (84.4% vs. 64.2%; P <0.001). On multivariate analysis, intensive care unit (ICU) admission and admission from home were associated with longer and shorter LOS, respectively. Despite less than anticipated adherence, these data suggest that the established disease state management guideline can improve outcomes in patients admitted with UTI.

As part of a needs analysis preceding the development of an e-learning platform on infection prevention, European intensive care unit (ICU) nurses were subjected to a knowledge test on evidence-based guidelines for preventing ventilator-associated pneumonia (VAP). A validated multiple-choice questionnaire was distributed to 22 European countries between October 2006 and March 2007. Demographics included nationality, gender, ICU experience, number of ICU beds and acquisition of a specialised degree in intensive care. We collected 3329 questionnaires (response rate 69.1%). The average score was 45.1%. Fifty-five percent of respondents knew that the oral route is recommended for intubation; 35% knew that ventilator circuits should be changed for each new patient; 38% knew that heat and moisture exchangers were the recommended humidifier type, but only 21% knew that these should be changed once weekly; closed suctioning systems were recommended by 46%, and 18% knew that these must be changed for each new patient only; 51% and 57%, respectively, recognised that subglottic drainage and kinetic beds reduce VAP incidence. Most (85%) knew that semi-recumbent positioning prevents VAP. Professional seniority and number of ICU beds were shown to be independently associated with better test scores. Further research may determine whether low scores are related to a lack of knowledge, deficiencies in training, differences in what is regarded as good practice, and/or a lack of consistent policy.

Usefulness of Glycemic Gap to Predict ICU Mortality in Critically Ill Patients With Diabetes.

Stress-induced hyperglycemia (SIH) has been independently associated with an increased risk of mortality in critically ill patients without diabetes. However, it is also necessary to consider preexisting hyperglycemia when investigating the relationship between SIH and mortality in patients with diabetes. We therefore assessed whether the gap between admission glucose and A1C-derived average glucose (ADAG) levels could be a predictor of mortality in critically ill patients with diabetes.We retrospectively reviewed the Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores and clinical outcomes of patients with diabetes admitted to our medical intensive care unit (ICU) between 2011 and 2014. The glycosylated hemoglobin (HbA1c) levels were converted to the ADAG by the equation, ADAG = [(28.7 × HbA1c) - 46.7]. We also used receiver operating characteristic (ROC) curves to determine the optimal cut-off value for the glycemic gap when predicting ICU mortality and used the net reclassification improvement (NRI) to measure the improvement in prediction performance gained by adding the glycemic gap to the APACHE-II score.We enrolled 518 patients, of which 87 (17.0%) died during their ICU stay. Nonsurvivors had significantly higher APACHE-II scores and glycemic gaps than survivors (P < 0.001). Critically ill patients with diabetes and a glycemic gap ≥80 mg/dL had significantly higher ICU mortality and adverse outcomes than those with a glycemic gap <80 mg/dL (P < 0.001). Incorporation of the glycemic gap into the APACHE-II score increased the discriminative performance for predicting ICU mortality by increasing the area under the ROC curve from 0.755 to 0.794 (NRI = 13.6%, P = 0.0013).The glycemic gap can be used to assess the severity and prognosis of critically ill patients with diabetes. The addition of the glycemic gap to the APACHE-II score significantly improved its ability to predict ICU mortality.

There is no established national standard for rib fracture management. A clinical practice guideline (CPG) for rib fractures, including monitoring of pulmonary function, early initiation of aggressive loco-regional analgesia, and early identification of deteriorating respiratory function, was implemented in 2013. The objective of the study was to evaluate the effect of the CPG on hospital length of stay. Hospital length of stay (LOS) was compared for adult patients admitted to the hospital with rib fracture(s) two years before and two years after CPG implementation. A separate analysis was done for the patients admitted to the intensive care unit (ICU). Over the 48-month study period, 571 patients met inclusion criteria for the study. Pre-CPG and CPG study groups were well matched with few differences. Multivariable regression did not demonstrate a difference in LOS (B = -0.838; P = 0.095) in the total study cohort. In the ICU cohort (n = 274), patients in the CPG group were older (57 vs 52 years; P = 0.023) and had more rib fractures (4 vs 3; P = 0.003). Multivariable regression identified a significant decrease in LOS for those patients admitted in the CPG period (B = -2.29; P = 0.019). Despite being significantly older with more rib fractures in the ICU cohort, patients admitted after implementation of the CPG had a significantly reduced LOS on multivariable analysis, reducing LOS by over two days. This structured intervention can limit narcotic usage, improve pulmonary function, and decrease LOS in the most injured patients with chest trauma.

Background Emergency manuals, which are safety essentials in non-medical high-reliability organizations (e.g., aviation), have recently gained acceptance in critical medical environments. Of the existing emergency manuals in anesthesiology, most are geared towards intraoperative settings. Additionally, most evidence supporting their efficacy focuses on the study of physicians with at least some meaningful experience as a physician. Our aim was to evaluate whether an emergency manual would improve the performance of novice physicians (post-graduate year [PGY] 1 or first year resident) in managing a critical event in the intensive care unit (ICU). Methods PGY1 interns (n=41) were assessed on the management of a simulated critical event (unstable bradycardia) in the ICU. Participants underwent a group allocation process to either a control group (n=18) or an intervention group (emergency manual provided, n=23). The number of successfully executed treatment and diagnostic interventions completed was evaluated over a ten minute (600 seconds) simulation for each participant. Results The participants using the emergency manual averaged 9.9/12 (83%) interventions, compared to an average of 7.1/12 (59%) interventions (p < 0.01) in the control group. Conclusions The use of an emergency manual was associated with a significant improvement in critical event management by individual novice physicians in a simulated ICU patient (23% average increase).

Blurred Lines: Dysbiosis and Probiotics in the ICU.

PubMed

Morrow, Lee E; Wischmeyer, Paul

2017-02-01

Clinicians have traditionally dichotomized bacteria as friendly commensals or harmful pathogens. However, the line separating the two has become blurred with the recognition that the intestinal microbiome is a complex entity in which species can shift sides-from friend to foe and back again-based on crucial factors in their local environment. Significant disruptions in the homeostasis of the microbiome, a phenomenon called dysbiosis, is increasingly associated with a host of untoward effects. Patients in the ICU are at high risk for dysbiosis given the high rate of antibiotic use, acute changes in diet, and the stress of critical illness. Probiotics are living microbes of human origin that when ingested in sufficient quantities, can colonize sites such as the oropharynx and GI tract and provide benefits to the host. In recent years, we have increasingly explored the utility of using probiotics to reverse the intestinal dysbiosis associated with critical illness, thereby reducing select ICU complications associated with increased morbidity and mortality. Although these preliminary efforts have demonstrated varying degrees of success, our present studies suffer from a host of limitations that hinder the strength of their conclusions and the generalizability of their results. Probiotic investigations have been further hobbled by current regulatory requirements, which were designed to serve as the framework for pharmaceutical research. Although such measures are intended to ensure patient safety, they inadvertently impose barriers that stifle innovation regarding nutraceuticals. This review strives to summarize the current evidence regarding the efficacy and safety of probiotics in the ICU as well as to provide an overview of the obstacles probiotic researchers face going forward.

Cumulative lactate and hospital mortality in ICU patients

PubMed Central

2013-01-01

Background Both hyperlactatemia and persistence of hyperlactatemia have been associated with bad outcome. We compared lactate and lactate-derived variables in outcome prediction. Methods Retrospective observational study. Case records from 2,251 consecutive intensive care unit (ICU) patients admitted between 2001 and 2007 were analyzed. Baseline characteristics, all lactate measurements, and in-hospital mortality were recorded. The time integral of arterial blood lactate levels above the upper normal threshold of 2.2 mmol/L (lactate-time-integral), maximum lactate (max-lactate), and time-to-first-normalization were calculated. Survivors and nonsurvivors were compared and receiver operating characteristic (ROC) analysis were applied. Results A total of 20,755 lactate measurements were analyzed. Data are srpehown as median [interquartile range]. In nonsurvivors (n = 405) lactate-time-integral (192 [0–1881] min·mmol/L) and time-to-first normalization (44.0 [0–427] min) were higher than in hospital survivors (n = 1846; 0 [0–134] min·mmol/L and 0 [0–75] min, respectively; all p < 0.001). Normalization of lactate <6 hours after ICU admission revealed better survival compared with normalization of lactate >6 hours (mortality 16.6% vs. 24.4%; p < 0.001). AUC of ROC curves to predict in-hospital mortality was the largest for max-lactate, whereas it was not different among all other lactate derived variables (all p > 0.05). The area under the ROC curves for admission lactate and lactate-time-integral was not different (p = 0.36). Conclusions Hyperlactatemia is associated with in-hospital mortality in a heterogeneous ICU population. In our patients, lactate peak values predicted in-hospital mortality equally well as lactate-time-integral of arterial blood lactate levels above the upper normal threshold. PMID:23446002

The aims were to 1) determine feasibility of measuring physical function in our ICU Recovery Clinic (RC), 2) determine if physical function was associated with 6-month re-hospitalization and 1-year mortality and 3) compare ICU survivors' physical function to other comorbid populations. We established the Wake Forest ICU RC. Patients were seen in clinic 1month following hospital discharge. Testing included the Short Form-36 questionnaire and Short Physical Performance Battery (SPPB). We related these measures to 6month re-hospitalizations and 1year mortality, and compared patients' functional performance with other comorbid populations. Thirty-six patients were seen in clinic from July 2014 to June 2015; the median SPPB score was 5 (IQR 5). The median SF-36 physical component summary score was 21.8 (IQR 28.8). Mortality was 14% at 1year. Of those who did not die by 1year, 35% were readmitted to our hospital within 6months of hospital discharge. SPPB scores demonstrated a non-significant trend with both mortality (p=0.06) and readmissions (p=0.09). ICU survivors' SPPB scores were significantly lower than those of other chronically ill populations (p<0.001). Physical function measurement in a recovery clinic is feasible and may inform subsequent morbidity and mortality. Copyright © 2018 Elsevier Inc. All rights reserved.

Respiratory infections account for significant morbidity, mortality and expenses to patients getting admitted to ICU. Antibiotic resistance is a major worldwide concern in ICU, including India. It is important to know the antibiotic prescribing pattern in ICU, organisms and its resistance pattern as there is sparse data on Indian ICUs. We conducted a prospective study from August 2015 to February 2016. All patients getting admitted to RICU with respiratory infection who were treated with antibiotics were included into study. Demographic details, comorbidities, Clinco-pathological score (CPI) on day1 and 2 of admission, duration of ICU admission, number of antibiotics used, antibiotic prescription, antimicrobial resistance pattern of patients were collected using APRISE questionnaire. During study period 352 patients were screened and 303 patients were included into study. Mean age was 56.05±16.37 and 190 (62.70%) were men. Most common diagnosis was Pneumonia (66%). Piperacillin-tazobactam was most common empirical antibiotic used. We found 60% resistance to piperacillin-tazobactam. Acinetobacter baumanii was the most common organism isolated (29.2%) and was highly resistant to Carbapenem (60%). Klebsiella pneumoniae was resistant to Amikacin (45%), piperacillin (55%) and Ceftazidime (50%). Piperacillin-tazobactam was the most common antibiotic prescribed to patients with respiratory infection admitted to ICU. More than half of patients (60%) had resistance to the empirical antibiotic used in our ICU, highlighting the need for antibiogram for each ICU. Thirty six percent of patient had prior antibiotic use and had mainly gram negative organisms with high resistance to commonly used antibiotics.

2016-12-01

The aim of this retrospective study was to analyze differences in the initial hemodynamic assessment and its impact on the treatment in patients aged 80 years or older compared to younger patients during the first 6 h after admission to the medical intensive care unit (ICU). We analyzed 615 consecutive patients admitted to the medical ICU of which 124 (20%) were aged 80 years or more. The older group had a significantly higher acute physiology and chronic health evaluation (APACHE II) score, an overall mortality in the ICU and a presence of pre-existing cardiac disease. Both groups did not differ in the presence of shock and shock types on admission. In 57% of older and in 56% of younger patients, transthoracic echocardiography was performed with a higher therapeutic impact in the older patients. Transesophageal echocardiography was performed in 3% of the patients in both groups for specific diagnostic problems. Early reassessment with transthoracic echocardiography was necessary in 5% of the older and in 6% of the younger patients and resulted in a change of the treatment in one third of the patients. Continuous invasive hemodynamic monitoring was used in 11% of the older and in 10% of the younger patients and resulted in a therapeutic change in 71% of the older and in 64% of the younger patients. Patients aged 80 years or older represent 20% of all admissions to the medical ICU. Once admitted the older patients were similarly hemodynamically assessed as the younger ones with a similar impact on the treatment.

To investigate whether the proactive intervention of a clinical ethicist in cases of prolonged lengths of stay in a critical care setting reduces nonbeneficial treatment while increasing perceived patient/surrogate and provider satisfaction and reducing associated costs. Nonbeneficial treatment is defined here as the use of life-sustaining treatments delivered to patients who had been in the ICU for 5 days and did not survive to discharge. Prospective randomized exploratory trial from October 2007 to February 2010 in the adult ICU of a large, urban, not-for-profit community hospital. Medical/surgical ICU of California Pacific Medical Center, a large tertiary not-for-profit hospital in San Francisco, CA. Three hundred eighty-four patients with ICU lengths of stay of five days or greater. Patients were randomized to either an intervention arm (Proactive Ethics Intervention) (n = 174) or control arm (n = 210). There were 56 patients in the intervention arm and 52 patients in the control arm who did not survive to discharge. Proactive ethics intervention involves a trained bioethicist in the care of all ICU patients with a length of stay greater than or equal to 5 days. The intervention used a nine step process model designed to look for manifest or latent ethics conflicts and address them. The primary outcome measures were days in the ICU; overall length of hospital stay; mortality; nonbeneficial treatments, for example, provision of nutritional support; surrogate and survivor satisfaction, and cost. The intervention and control arms showed no significant difference in mortality. Proactive Ethics Intervention, at the 95% CI, was not associated with reductions of overall length of stay (23 d for intervention and 21 d for control, p = 0.74), ICU days (11 in each arm, p = 0.91), life-sustaining treatments (days on ventilator: intervention, 14.6; control, 13.7; p = 0.74; days receiving artificial nutrition and hydration: intervention, 16.5; control, 15.9; p = 0.85), or

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]).

Background Despite the expansion of ethics consultation services, questions remain about the aims of clinical ethics consultation, its methods and the expertise of those who provide such services. Objective To describe physicians' expectations regarding the training and skills necessary for ethics consultants to contribute effectively to the care of patients in intensive care unit (ICU). Design Mailed survey. Participants Physicians responsible for the care of at least 10 patients in ICU over a 6‐month period at a 921‐bed private teaching hospital with an established ethics consultation service. 69 of 92 (75%) eligible physicians responded. Measurements Importance of specialised knowledge and skills for ethics consultants contributing to the care of patients in ICU; need for advanced disciplinary training; expectations regarding formal‐training programmes for ethics consultants. Results Expertise in ethics was described most often as important for ethics consultants taking part in the care of patients in ICU, compared with expertise in law (p<0.03), religious traditions (p<0.001), medicine (p<0.001) and conflict‐mediation techniques (p<0.001). When asked about the formal training consultants should possess, however, physicians involved in the care of patients in ICU most often identified advanced medical training as important. Conclusions Although many physicians caring for patients in ICU believe ethics consultants must possess non‐medical expertise in ethics and law if they are to contribute effectively to patient care, these physicians place a very high value on medical training as well, suggesting a “medicine plus one” view of the training of an ideal ethics consultant. As ethics consultation services expand, clear expectations regarding the training of ethics consultants should be established. PMID:17526680

An Unusual Case of Refractory Hypoxia on the ICU

We present the case of a 68-year-old gentleman who presented with breathlessness and was found to have NSTEMI, pulmonary oedema, and hypoxia. He remained hypoxic despite appropriate treatment and was found to have preserved LV function and raised cardiac output. CT pulmonary angiogram was negative but a cirrhotic liver was incidentally noted and later confirmed via ultrasound. Bedside examination was positive for orthodeoxia, suggesting a diagnosis of hepatopulmonary syndrome (HPS). The finding of significant intrapulmonary shunting on “bubble” echocardiography confirmed the diagnosis. This patient did not have previously diagnosed liver disease and had largely normal LFTs when the diagnosis was first suspected. We discuss HPS in the context of ICU and suggest how it may be screened for using simple tests. There is no correlation between the presence of HPS and severity of liver disease, yet we believe this is the first reported adult case of HPS on the ICU without previously diagnosed cirrhosis.

Renal outcomes after critical illness are seldom assessed despite strong correlation between chronic kidney disease and survival. Outside hospital, renal dysfunction is more strongly associated with mortality when assessed by serum cystatin C than by creatinine. The relationship between creatinine and longer term mortality might be particularly weak in survivors of critical illness. Retrospective observational cohort study. In 3,077 adult ICU survivors, we compared ICU discharge cystatin C and creatinine and their association with 1-year mortality. Exclusions were death within 72 hours of ICU discharge, ICU stay less than 24 hours, and end-stage renal disease. None. During ICU admission, serum cystatin C and creatinine diverged, so that by ICU discharge, almost twice as many patients had glomerular filtration rate less than 60 mL/min/1.73 m when estimated from cystatin C compared with glomerular filtration rate estimated from creatinine, 44% versus 26%. In 743 patients without acute kidney injury, where ICU discharge renal function should reflect ongoing baseline, discharge glomerular filtration rate estimated from creatinine consistently overestimated follow-up glomerular filtration rate estimated from creatinine, whereas ICU discharge glomerular filtration rate estimated from cystatin C well matched follow-up chronic kidney disease status. By 1 year, 535 (17.4%) had died. In survival analysis adjusted for age, sex, and comorbidity, cystatin C was near-linearly associated with increased mortality, hazard ratio equals to 1.78 (95% CI, 1.46-2.18), 75th versus 25th centile. Conversely, creatinine demonstrated a J-shaped relationship with mortality, so that in the majority of patients, there was no significant association with survival, hazard ratio equals to 1.03 (0.87-1.2), 75th versus 25th centile. After adjustment for both creatinine and cystatin C levels, higher discharge creatinine was then associated with lower long-term mortality. In contrast to creatinine

Due to accuracy concerns, the Food and Drug Administration issued guidances to manufacturers that resulted in Center for Medicare and Medicaid Services stating that the use of meters in critically ill patients is "off-label" and constitutes "high complexity" testing. This is causing significant workflow problems in ICUs nationally. We wished to determine whether real-world accuracy of modern glucose meters is worse in ICU patients compared with non-ICU inpatients. We reviewed glucose results over the preceding 3 years, comparing results from paired glucose meter and central laboratory tests performed within 60 minutes of each other in ICU versus non-ICU settings. Seven ICU and 30 non-ICU wards at a 1,300-bed academic hospital in the United States. A total of 14,763 general medicine/surgery inpatients and 20,970 ICU inpatients. None. Compared meter results with near simultaneously performed laboratory results from the same patient by applying the 2016 U.S. Food and Drug Administration accuracy criteria, determining mean absolute relative difference and examining where paired results fell within the Parkes consensus error grid zones. A higher percentage of glucose meter results from ICUs than from non-ICUs passed 2016 Food and Drug Administration accuracy criteria (p < 10) when comparing meter results with laboratory results. At 1 minute, no meter result from ICUs posed dangerous or significant risk by error grid analysis, whereas at 10 minutes, less than 0.1% of ICU meter results did, which was not statistically different from non-ICU results. Real-world accuracy of modern glucose meters is at least as accurate in the ICU setting as in the non-ICU setting at our institution.

Amoxicillin/clavulanate (Augmentin) resistant Escherichia coli in bacterial peritonitis after abdominal surgery--clinical outcome in ICU patients.

PubMed

Rahnama'i, M S; Wagenvoort, J H T; van der Linden, C J

2009-05-01

Bacterial resistance to antimicrobial agents is of great concern to clinicians. Patient outcome after infection is mainly dependent on the sensitivity of the bacterium to the agent used. We retrospectively studied 89 postoperative intensive care unit (ICU) patients with proven Escherichia coli peritonitis and investigated the clinical consequences of the E. coli resistance to amoxicillin/clavulanate. Significantly increased mortality, days of ventilation and ICU stay were noted in the co-amoxicillin/clavulanate resistant group. Furthermore, our results demonstrate that the sensitivity of E. coli to amoxicillin/clavulanate in the postoperative ICU setting has decreased in recent years. We can conclude that the current antibiotic regimen for the empirical treatment of ICU patients with peritonitis, as used in our hospital, needs to be changed. A switch, for instance, to ceftriaxone (Rocephin) in combination with metronidazole and gentamicin, instead of the present regimen of amoxicillin/clavulanate in combination with gentamicin, seems preferable.

ICU director data: using data to assess value, inform local change, and relate to the external world.

Improving value within critical care remains a priority because it represents a significant portion of health-care spending, faces high rates of adverse events, and inconsistently delivers evidence-based practices. ICU directors are increasingly required to understand all aspects of the value provided by their units to inform local improvement efforts and relate effectively to external parties. A clear understanding of the overall process of measuring quality and value as well as the strengths, limitations, and potential application of individual metrics is critical to supporting this charge. In this review, we provide a conceptual framework for understanding value metrics, describe an approach to developing a value measurement program, and summarize common metrics to characterize ICU value. We first summarize how ICU value can be represented as a function of outcomes and costs. We expand this equation and relate it to both the classic structure-process-outcome framework for quality assessment and the Institute of Medicine's six aims of health care. We then describe how ICU leaders can develop their own value measurement process by identifying target areas, selecting appropriate measures, acquiring the necessary data, analyzing the data, and disseminating the findings. Within this measurement process, we summarize common metrics that can be used to characterize ICU value. As health care, in general, and critical care, in particular, changes and data become more available, it is increasingly important for ICU leaders to understand how to effectively acquire, evaluate, and apply data to improve the value of care provided to patients.

There are numerous challenges in providing nutrition to the mechanically ventilated critically ill ICU patient. Understanding the level of nutritional support and the barriers to enteral feeding interruption in mechanically ventilated patients are important to maximise the nutritional benefits to the critically ill patients. Thus, this study aims to evaluate enteral nutrition delivery and identify the reasons for interruptions in mechanically ventilated Malaysian patients receiving enteral feeding. A cross sectional prospective study of 77 consecutive patients who required mechanical ventilation and were receiving enteral nutrition was done in an open 14-bed intensive care unit of a tertiary hospital. Data were collected prospectively over a 3 month period. Descriptive statistical analysis were made with respect to demographical data, time taken to initiate feeds, type of feeds, quantification of feeds attainment, and reasons for feed interruptions. There are no set feeding protocols in the ICU. The usual initial rate of enteral nutrition observed in ICU was 20 ml/hour, assessed every 6 hours and the decision was made thereafter to increase feeds. The target calorie for each patient was determined by the clinician alongside the dietitian. The use of prokinetic agents was also prescribed at the discretion of the attending clinician and is commonly IV metoclopramide 10 mg three times a day. About 66% of patients achieved 80% of caloric requirements within 3 days of which 46.8% achieved full feeds in less than 12 hours. The time to initiate feeds for patients admitted into the ICU ranged from 0 - 110 hours with a median time to start feeds of 15 hours and the interquartile range (IQR) of 6-59 hours. The mean time to achieve at least 80% of nutritional target was 1.8 days ± 1.5 days. About 79% of patients experienced multiple feeding interruptions. The most prevalent reason for interruption was for procedures (45.1%) followed by high gastric residual volume (38

The goals of this project were to compare both the anatomic and physiologic severity scores in trauma patients admitted to intensive care unit (ICU), and to elaborate mixed statistical models to improve the precision of the scores. A prospective study of cohorts. The combined medical/surgical ICU in a secondary university hospital. Seven hundred and eighty trauma patients admitted to ICU older than 16 years of age. Anatomic models (ISS and NISS) were compared and combined with physiological models (T-RTS, APACHE II [APII], and MPM II). The probability of death was calculated following the TRISS method. The discrimination was assessed using ROC curves (ABC [CI 95%]), and the calibration using the Hosmer-Lemeshoẃs H test. The mixed models were elaborated with the tree classification method type Chi Square Automatic Interaction Detection. A 14% global mortality was recorded. The physiological models presented the best discrimination values (APII of 0.87 [0.84-0.90]). All models were affected by bad calibration (P<.01). The best mixed model resulted from the combination of APII and ISS (0.88 [0.83-0.90]). This model was able to differentiate between a 7.5% mortality for elderly patients with pathological antecedents and a 25% mortality in patients presenting traumatic brain injury, from a pool of patients with APII values ranging from 10 to 17 and an ISS threshold of 22. The physiological models perform better than the anatomical models in traumatic patients admitted to the ICU. Patients with low scores in the physiological models require an anatomic analysis of the injuries to determine their severity. Copyright © 2017 Elsevier España, S.L.U. y SEMICYUC.

Hospital-level variations in structure and process may affect clinical outcomes in ICUs. We sought to characterize the organizational structure, processes of care, use of protocols, and standardized outcomes in a large sample of U.S. ICUs. We surveyed 69 ICUs about organization, size, volume, staffing, processes of care, use of protocols, and annual ICU mortality. ICUs participating in the United States Critical Illness and Injury Trials Group Critical Illness Outcomes Study. Sixty-nine intensivists completed the survey. We characterized structure and process variables across ICUs, investigated relationships between these variables and annual ICU mortality, and adjusted for illness severity using Acute Physiology and Chronic Health Evaluation II. Ninety-four ICU directors were invited to participate in the study and 69 ICUs (73%) were enrolled, of which 25 (36%) were medical, 24 (35%) were surgical, and 20 (29%) were of mixed type, and 64 (93%) were located in teaching hospitals with a median number of five trainees per ICU. Average annual ICU mortality was 10.8%, average Acute Physiology and Chronic Health Evaluation II score was 19.3, 58% were closed units, and 41% had a 24-hour in-house intensivist. In multivariable linear regression adjusted for Acute Physiology and Chronic Health Evaluation II and multiple ICU structure and process factors, annual ICU mortality was lower in surgical ICUs than in medical ICUs (5.6% lower [95% CI, 2.4-8.8%]) or mixed ICUs (4.5% lower [95% CI, 0.4-8.7%]). We also found a lower annual ICU mortality among ICUs that had a daily plan of care review (5.8% lower [95% CI, 1.6-10.0%]) and a lower bed-to-nurse ratio (1.8% lower when the ratio decreased from 2:1 to 1.5:1 [95% CI, 0.25-3.4%]). In contrast, 24-hour intensivist coverage (p = 0.89) and closed ICU status (p = 0.16) were not associated with a lower annual ICU mortality. In a sample of 69 ICUs, a daily plan of care review and a lower bed-to-nurse ratio were both associated with a

Areflexic quadriplegia that occurs in the intensive care unit (ICU) is commonly ascribed to critical illness polyneuropathy based upon electrophysiology or muscle light microscopy. However, electron microscopy often documents a selective thick filament loss myopathy. Eight ICU patients who developed areflexic quadriplegia underwent biopsy. Seven patients had received steroids, and 2 had also received paralytic agents. Electrodiagnostic studies revealed absent or low-amplitude motor responses in 7. Sensory responses were normal in 5 of 6 and absent in 1. Initial electromyography revealed absent (n = 3), small (n = 3), or polyphasic (n = 1) motor unit potentials, and diffuse fibrillation potentials (n = 5). In all 8, light microscopy of muscle revealed numerous atrophic-angulated fibers and corelike lesions, and electron microscopy revealed extensive thick filament loss. Morphology of sural and intramuscular nerves, and, in one autopsied case, of the obturator nerve and multiple nerve roots, was normal. Although clinical, electrodiagnostic, and light microscopic features mimicked denervating disease, muscle electron microscopy revealed thick filament loss, and nerve histology was normal. This suggests that areflexic ICU quadriplegia is a primary myopathy and not an axonal polyneuropathy. Copyright 2002 Wiley Periodicals, Inc. Muscle Nerve 26: 499-505, 2002

Background Effective communication is essential to safe and efficient patient care. Additionally, many health information technology (HIT) developments, innovations, and standards aim to implement processes to improve data quality and integrity of electronic health records (EHR) for the purpose of clinical information exchange and communication. Objective We aimed to understand the current patterns and perceptions of communication of common goals in the ICU using the distributed cognition and clinical communication space theoretical frameworks. Methods We conducted a focus group and 5 interviews with ICU clinicians and observed 59.5 hours of interdisciplinary ICU morning rounds. Results Clinicians used an EHR system, which included electronic documentation and computerized provider order entry (CPOE), and paper artifacts for documentation; yet, preferred the verbal communication space as a method of information exchange because they perceived that the documentation was often not updated or efficient for information retrieval. These perceptions that the EHR is a “shift behind” may lead to a further reliance on verbal information exchange, which is a valuable clinical communication activity, yet, is subject to information loss. Conclusions Electronic documentation tools that, in real time, capture information that is currently verbally communicated may increase the effectiveness of communication. PMID:23616870

This study evaluated the impact of a simulation-based mastery learning (SBML) curriculum on central line maintenance and care among a group of ICU nurses. The intervention included 5 tasks: (a) medication administration, (b) injection cap (needleless connector) changes, (c) tubing changes, (d) blood drawing, and (e) dressing changes. All participants underwent a pretest, engaged in deliberate practice with directed feedback, and completed a posttest. We compared pretest and posttest scores and assessed correlations between demographics, self-confidence, and pretest performance. The number of nurses passing each task at pretest varied from 24 of 49 (49%) for dressing changes to 44 of 49 (90%) for tubing changes. At pretest, scores ranged from a median of 0.0% to 73.1%. At posttest, all scores rose to a median of 100.0%. Total years in nursing and ICU nursing had significant, negative correlations with medication administration pretest performance (r = -0.42, P = .003; r = -0.42, P = .003, respectively). ICU nurses displayed large variability in their ability to perform central line maintenance tasks. After SBML, there was significant improvement, and all nurses reached a predetermined level of competency.

Conflict is common between physicians and surrogate decision makers around end-of-life care in ICU. Involving experts in conflict management improve outcomes, but little is known about what differences in conflict management styles may explain the benefit. We used simulation to examine potential differences in how palliative care specialists manage conflict with surrogates about end-of-life treatment decisions in ICUs compared with intensivists. Subjects participated in a high-fidelity simulation of conflict with a surrogate in an ICU. In this simulation, a medical actor portrayed a surrogate decision maker during an ICU family meeting who refuses to follow an advance directive that clearly declines advanced life-sustaining therapies. We audiorecorded the simulation encounters and applied a coding framework to quantify conflict management behaviors, which was organized into two categories: task-focused communication and relationship building. We used negative binomial modeling to determine whether there were differences between palliative care specialists' and intensivists' use of task-focused communication and relationship building. Single academic medical center ICU. Palliative care specialists and intensivists. None. We enrolled 11 palliative care specialists and 25 intensivists. The palliative care specialists were all attending physicians. The intensivist group consisted of 11 attending physicians, 9 pulmonary and critical care fellows, and 5 internal medicine residents rotating in the ICU. We excluded five residents from the primary analysis in order to reduce confounding due to training level. Physicians' mean age was 37 years with a mean of 8 years in practice. Palliative care specialists used 55% fewer task-focused communication statements (incidence rate ratio, 0.55; 95% CI, 0.36-0.83; p = 0.005) and 48% more relationship-building statements (incidence rate ratio, 1.48; 95% CI, 0.89-2.46; p = 0.13) compared with intensivists. We found that palliative care

Sepsis is among the leading causes of morbidity, mortality, and cost overruns in critically ill patients. Early intervention with antibiotics improves survival in septic patients. However, no clinically validated system exists for real-time prediction of sepsis onset. We aimed to develop and validate an Artificial Intelligence Sepsis Expert algorithm for early prediction of sepsis. Observational cohort study. Academic medical center from January 2013 to December 2015. Over 31,000 admissions to the ICUs at two Emory University hospitals (development cohort), in addition to over 52,000 ICU patients from the publicly available Medical Information Mart for Intensive Care-III ICU database (validation cohort). Patients who met the Third International Consensus Definitions for Sepsis (Sepsis-3) prior to or within 4 hours of their ICU admission were excluded, resulting in roughly 27,000 and 42,000 patients within our development and validation cohorts, respectively. None. High-resolution vital signs time series and electronic medical record data were extracted. A set of 65 features (variables) were calculated on hourly basis and passed to the Artificial Intelligence Sepsis Expert algorithm to predict onset of sepsis in the proceeding T hours (where T = 12, 8, 6, or 4). Artificial Intelligence Sepsis Expert was used to predict onset of sepsis in the proceeding T hours and to produce a list of the most significant contributing factors. For the 12-, 8-, 6-, and 4-hour ahead prediction of sepsis, Artificial Intelligence Sepsis Expert achieved area under the receiver operating characteristic in the range of 0.83-0.85. Performance of the Artificial Intelligence Sepsis Expert on the development and validation cohorts was indistinguishable. Using data available in the ICU in real-time, Artificial Intelligence Sepsis Expert can accurately predict the onset of sepsis in an ICU patient 4-12 hours prior to clinical recognition. A prospective study is necessary to determine the

Intensive care frequently results in unintentional harm to patients and statistics don’t seem to improve. The ICU environment is especially unforgiving for mistakes due to the multidisciplinary, time-critical nature of care and vulnerability of the patients. Human factors account for the majority of adverse events and a sound safety climate is therefore essential. This article reviews the existing literature on aviation-derived training called Crew Resource Management (CRM) and discusses its application in critical care medicine. CRM focuses on teamwork, threat and error management and blame free discussion of human mistakes. Though evidence is still scarce, the authors consider CRM to be a promising tool for culture change in the ICU setting, if supported by leadership and well-designed follow-up. PMID:22913855

Big data analytics promise insights into healthcare processes and management, improving outcomes while reducing costs. However, data quality is a major challenge for reliable results. Business process discovery techniques and an associated data model were used to develop data management tool, ICU-DaMa, for extracting variables essential for overseeing the quality of care in the intensive care unit (ICU). To determine the feasibility of using ICU-DaMa to automatically extract variables for the minimum dataset and ICU quality indicators from the clinical information system (CIS). The Wilcoxon signed-rank test and Fisher's exact test were used to compare the values extracted from the CIS with ICU-DaMa for 25 variables from all patients attended in a polyvalent ICU during a two-month period against the gold standard of values manually extracted by two trained physicians. Discrepancies with the gold standard were classified into plausibility, conformance, and completeness errors. Data from 149 patients were included. Although there were no significant differences between the automatic method and the manual method, we detected differences in values for five variables, including one plausibility error and two conformance and completeness errors. Plausibility: 1) Sex, ICU-DaMa incorrectly classified one male patient as female (error generated by the Hospital's Admissions Department). Conformance: 2) Reason for isolation, ICU-DaMa failed to detect a human error in which a professional misclassified a patient's isolation. 3) Brain death, ICU-DaMa failed to detect another human error in which a professional likely entered two mutually exclusive values related to the death of the patient (brain death and controlled donation after circulatory death). Completeness: 4) Destination at ICU discharge, ICU-DaMa incorrectly classified two patients due to a professional failing to fill out the patient discharge form when thepatients died. 5) Length of continuous renal replacement

The Intensive Care Unit is not only a place where lives are saved; it is also a site of harm and iatrogenic injury for millions of people treated in this setting globally every year. Increasingly, hospitals admit only the sickest patients, and, while the overall number of hospital beds remains stable in the U.S., the percentage of that total devoted to ICU beds is rising. These two realities engender a demographic imperative to address patient safety in the critical care setting. This manuscript addresses the medical community’s resistance to adopting a culture of safety in critical care with regard to issues surrounding sedation, delirium, and early mobility. Although there is currently much research and quality improvement in this area, most of what we know from these data and published guidelines has not become reality in the day-to-day management of ICU patients. This manuscript is not intended to provide a comprehensive review of the literature, but rather a framework to rethink our currently outdated culture of critical care by employing Maslow’s Hierarchy of Needs, along with a few novel analogies. Application of Maslow’s Hierarchy will help propel healthcare professionals toward comprehensive care of the whole person, not merely for survival, but toward restoration of pre-illness function of mind, body, and spirit.

Alcohol is the leading psychoactive substance consumed in France, with about 15 million regular consumers. The National institute on Alcohol Abuse and Alcoholism (NIAAA) considers alcohol abuse to be more than 14 units of alcohol a week for men and 7 units for women. The specific complication of alcoholism is the alcohol withdrawal syndrome. Its incidence reaches up to 30 % and its main complications are delirium tremens, restlessness, extended hospital stay, higher morbidity, and psychiatric and cognitive impairment. Without appropriate treatment, delirium tremens can lead to death in up to 50 % of patients. This prospective, double-blind, randomised controlled study versus placebo will be conducted in twelve French intensive care units (ICU). Patients with an alcohol intake level higher than the NIAAA threshold, who are under mechanical ventilation, will be included. The primary objective is to determine whether baclofen is more efficient than placebo in preventing restlessness-related side effects in the ICU. Secondary outcomes include mechanical ventilation duration, length of ICU stay, and cumulative doses of sedatives and painkillers received within 28 days of ICU admission. Restlessness-related side effects in the ICU are defined as unplanned extubation, medical disposal removal (such as urinary catheter, venous or arterial line or surgical drain), falling out of bed, ICU runaway (leaving ICU without physician's approval), immobilisation device removal, self-aggression or aggression towards medical staff. Daily doses of baclofen/placebo will be guided by daily creatinine clearance assessment. Restlessness in alcoholic patients is a life-threatening issue in ICUs. BACLOREA is a randomised study assessing the capacity of baclofen to prevent agitation in mechanically ventilated patients. Enrolment of 314 patients will begin in June 2016 and is expected to end in October 2018. ClinicalTrials.gov Identifier: NCT02723383 , registered on 3 March 2016.

Hand washing is widely accepted as the cornerstone of infection control in the intensive care unit (ICU). Nosocomial infections are frequently viewed as indicating poor compliance with hand washing guidelines. To determine the hand hygiene (HH) compliance rate among healthcare workers (HCWs) and its effect on the nosocomial infection rates in the ICU of our hospital, we conducted an interventional study. The study spanned a period of 7 months (February 2011-August 2011) and consisted of education about HH indications and techniques, workplace reminder posters, focused group sessions, and feedback on the HH compliance and infection rates. The WHO HH observation protocol was used both before and after a hospital-wide HH campaign directed at all staff members, particularly those in the ICU. Compliance was measured by direct observation of the HCWs, using observation record forms in a patient-directed manner, with no more than two patients observed simultaneously. The overall HH compliance rate was calculated by dividing the number of HH actions by the total number of HH opportunities. The nosocomial infection rates for the pre- and post-interventional periods were also compared to establish the effect of the intervention on rate of infections acquired within the unit. The overall rate of HH compliance by all the HCWs increased from 42.9% pre-intervention to 61.4% post-intervention, P<0.001. Individually, the compliance was highest among the nurses, 49.9 vs. 82.5%, respectively (P<0.001) and lowest among the doctors, 38.6 vs. 43.2%, respectively (P=0.24). The effect of the increase in the HH compliance rate on the nosocomial infection rate was remarkable. There were significant reductions in the following: the rate of overall health care-associated infections/1000 patient-days, which fell from 37.2 pre-intervention to 15.1 post-intervention (P<0.001); the rate of bloodstream infections, which fell from 18.6 to 3.4/1000 central-line-days (P<0.001); and the rate of lower

Discomfort and noncompliance with noninvasive ventilation (NIV) interfaces are obstacles to NIV success. Total face masks (TFMs) are considered to be a very comfortable NIV interface. However, due to their large internal volume and consequent increased CO2 rebreathing, their orifices allow proximal leaks to enhance CO2 elimination. The ventilators used in the ICU might not adequately compensate for such leakage. In this study, we attempted to determine whether ICU ventilators in NIV mode are suitable for use with a leaky TFM. This was a bench study carried out in a university research laboratory. Eight ICU ventilators equipped with NIV mode and one NIV ventilator were connected to a TFM with major leaks. All were tested at two positive end-expiratory pressure (PEEP) levels and three pressure support levels. The variables analyzed were ventilation trigger, cycling off, total leak, and pressurization. Of the eight ICU ventilators tested, four did not work (autotriggering or inappropriate turning off due to misdetection of disconnection); three worked with some problems (low PEEP or high cycling delay); and one worked properly. The majority of the ICU ventilators tested were not suitable for NIV with a leaky TFM.

Limited information exists on the clinical characteristics predictive of mortality in patients aged ≥65 years in many countries. The impact of adherence to current antimicrobial guidelines on the mortality of hospitalized elderly patients with community-acquired pneumonia (CAP) has never been assessed. A total of 3131 patients aged ≥65 years were enrolled from a multi-center, retrospective, observational study initiated by the CAP-China network. Risk factors for death were screened with multivariable logistic regression analysis, with emphasis on the evaluation of age, comorbidities and antimicrobial treatment regimen with regard to the current Chinese CAP guidelines. The mean age of the study population was 77.4 ± 7.4 years. Overall in-hospital and 60-day mortality were 5.7% and 7.6%, respectively; these rates were three-fold higher in those aged ≥85 years than in the 65-74 group (11.9% versus 3.2% for in-hospital mortality and 14.1% versus 4.7% for 60-day mortality, respectively). The mortality was significantly higher among patients with comorbidities compared with those who were otherwise healthy. According to the 2016 Chinese CAP guidelines, 62.1% of patients (1907/3073) received non-adherent treatment. For general-ward patients without risk factors for Pseudomonas aeruginosa (PA) infection (n = 2258), 52.3% (1094/2090) were over-treated, characterized by monotherapy with an anti-pseudomonal β-lactam or combination with fluoroquinolone + β-lactam; while 71.4% of intensive care unit (ICU) patients (120/168) were undertreated, without coverage of atypical bacteria. Among patients with risk factors for PA infection (n = 815), 22.9% (165/722) of those in the general ward and 74.2% of those in the ICU (69/93) were undertreated, using regimens without anti-pseudomonal activity. The independent predictors of 60-day mortality were age, long-term bedridden status, congestive heart failure, CURB-65, glucose, heart rate, arterial oxygen

"Zero-VAP" is a proposal for the implementation of a simultaneous multimodal intervention in Spanish intensive care units (ICU) consisting of a bundle of ventilator-associated pneumonia (VAP) prevention measures. An initiative of the Spanish Societies of Intensive Care Medicine and of Intensive Care Nurses, the project is supported by the Spanish Ministry of Health, and participation is voluntary. In addition to guidelines for VAP prevention, the "Zero-VAP" Project incorporates an integral patient safety program and continuous online validation of the application of the bundle. For the latter, VAP episodes and participation indices are entered into the web-based Spanish ICU Infection Surveillance Program "ENVIN-HELICS" database, which provides continuous information about local, regional and national VAP incidence rates. Implementation of the guidelines aims at the reduction of VAP to less than 9 episodes per 1000 days of mechanical ventilation. A total of 35 preventive measures were initially selected. A task force of experts used the Grading of Recommendations, Assessment, Development and Evaluation Working Group methodology to generate a list of 7 basic "mandatory" recommendations (education and training in airway management, strict hand hygiene for airway management, cuff pressure control, oral hygiene with chlorhexidine, semi-recumbent positioning, promoting measures that safely avoid or reduce time on ventilator, and discouraging scheduled changes of ventilator circuits, humidifiers and endotracheal tubes) and 3 additional "highly recommended" measures (selective decontamination of the digestive tract, aspiration of subglottic secretions, and a short course of iv antibiotic). We present the Spanish VAP prevention guidelines and describe the methodology used for the selection and implementation of the recommendations and the organizational structure of the project. Compared to conventional guideline documents, the associated safety assurance program, the

Many bereaved family members (FMs) of intensive care unit decedents experience symptoms of complicated grief (CG) or social distress, but there is no standard screening or follow-up for these individuals. We determined the desirability and need for an intensive care unit-based bereavement screening and support program for these FMs. We surveyed bereaved FMs to measure symptoms of CG, prolonged grief disorder, and social difficulties and the desire for support; and staff physicians and nurses at 2 teaching hospitals in Toronto, Canada, to determine comfort and interest in providing routine bereavement support. We could not contact 69% of FMs largely because of inaccuracies in the patient record. Of the 64 who were contacted, 32 (50%) agreed to be surveyed a mean (SD) of 7.4 (2.2) months after the loss of their relative. Among eligible staff, 57 (61%) of 94 completed the questionnaire. Nine (28%) FMs met subthreshold criteria for CG or prolonged grief disorder, and 7 (22%) met criteria for social distress. Only 10 (31%) had received professional support for emotional symptoms, and 2 (6%) received professional assistance for their social difficulties. Fifty-eight percent supported routine screening, and 68% wanted to receive (or receive more) support. Fifty-five percent of FMs expressed a strong willingness to meet with the medical team to review events surrounding the death of the patient, which was the type of support that the health care staff were most comfortable providing. Most staff (85%) reported providing emotional support at the time of death, but few provided any support afterwards. Fifty-six (98%) of 57 would be willing to support or participate in a formal bereavement screening and support program. Respondents cited the need for training and dedicated time to carry out such a program. An ICU-based bereavement screening and support program for FMs of ICU decedents is both needed and desirable, although there are important needs and barriers. Future studies

Use of Augmentative and Assistive Communication Strategies by Family Members in the ICU

Broyles, Lauren M.; Tate, Judith A.; Happ, Mary Beth

2013-01-01

Background Very little is known about patient-family communication during critical illness and mechanical ventilation in the intensive care unit (ICU), including the use of augmentative and alternative communication (AAC) tools and strategies during patient-family communication. Objectives The study objectives were to identify (1) which AAC tools families use with nonspeaking ICU patients and how they are used, and (2) what families and nurses say about patient-family communication with nonspeaking patients in the ICU. Methods A qualitative secondary analysis was conducted of existing data from a clinical trial testing interventions to improve nurse-patient communication in the ICU. Narrative study data (field notes, intervention logs, nurse interviews) from 127 critically ill adults were reviewed for evidence of family involvement with AAC tools. Qualitative content analysis was applied for thematic description of family and nurse accounts of patient-family communication. Results Family involvement with AAC tools was evident in 44% (n= 41/93) of the patients completing the parent study protocol. Spouses/significant others communicated with patients most often. Writing was the most frequently used tool. Main themes describing patient-family communication included: (1) Families as unprepared and unaware; (2) Family perceptions of communication effectiveness; (3) Nurses deferring to or guiding patient-family communication; (4) Patient communication characteristics; and (5) Family experience and interest with AAC tools. Conclusions Families are typically unprepared for the communication challenges of critical illness, and often “on their own” in confronting them. Assessment by skilled bedside clinicians can reveal patient communication potential and facilitate useful AAC tools and strategies for patients and families. PMID:22381993

We were interested in whether C-reactive protein (CRP) and procalcitonin (PCT) distinguish sepsis from non-septic controls and whether a combination of CRP, PCT, and neutrophil CD64 improves identification of sepsis in the intensive care unit (ICU). We analyzed the CRP and PCT concentrations from 27 patients with sepsis and 15 ICU controls. In addition, CD64 on neutrophils was measured using quantitative flow cytometry. We present a multiple marker analysis for sepsis diagnostics combining neutrophil CD64, CRP, and PCT using post-test analysis. The CRP and PCT values separated sepsis and non-septic ICU patients. In post-test analysis, CRP provided a positive probability of 0.48 and a negative probability of 0.053 for sepsis in the ICU; while, the corresponding values were 0.35 and 0.0059, respectively, for PCT and 0.62 and 0.0013, respectively, for neutrophil CD64. When neutrophil CD64 was analyzed with PCT and CRP, the probabilities were 0.98 and <0.001, respectively. Neutrophil CD64 expression was superior to PCT and CRP for the identification of sepsis in ICU. Positive post-test probability for any combinations of simultaneously analyzed CRP, PCT and CD64 showed improved diagnostic accuracy for sepsis. This approach may be useful for guiding antibiotic treatment in ICU. Copyright © 2017 Elsevier Inc. All rights reserved.

Multicenter study oriented at establishing the incidence and prognosis of acute kidney failure (AKF) in the ICU of our country. Prospective study of adult patients admitted over 8 months in 43 Spanish ICUs to detect AKF defined as creatinine>or=2 mg/dl or diuresis<400 ml/24 hours (in chronic patients 100% increase of creatinine, excluding those with baseline creatinine>or=4 mg/dl). 901 episodes of AKF (AKF episodes (incidence 5.7%), 55% of which occurred on admission. A total of 38.4% of the episodes were due to acute tubular necrosis (ATN), 36.6% to prerenal, and 21.2% to mixed. Renal depuration (RC) was required in 38%. Mortality was 42.3% during the AKF episode (34.1% in those who were admitted with AKF versus 50.9% in those who developed it after admission), 80% in patients with Hepatorenal Syndrome, 51.6% in ATN and 29.9% in prerenal. We detect an independent relationship with mortality for age (OR 1.03), background of diabetes (OR 2.06), development of AKF in the ICU (OR 2.51), oliguria (OR 5.76) and RC (OR 2.32). Recovery of the kidney function occurred in 85.6% of the survivors and RC was maintained in only 1.1% on discharge from the ICU. We calculated the area under the curve of APACHE II on admission (0.62), SOFA on onset of AKF (0.68), Liaño index (0.7) and maximum SOFA (0.79). AKF in ICU patients does not show an elevated incidence but does have high mortality, presenting greater seriousness when it appears after admission. However, recovery is elevated in patients who survive. The usual prognostic indexes are not exact in this patient group, the ISA and maximum SOFA being those which shows a closer relationship with mortality.

To assess the effect of body mass index on ICU outcome and on the development of ICU-acquired infection. A substudy of the Intensive Care Over Nations audit. Seven hundred thirty ICUs in 84 countries. All adult ICU patients admitted between May 8 and 18, 2012, except those admitted for less than 24 hours for routine postoperative monitoring (n = 10,069). In this subanalysis, only patients with complete data on height and weight (measured or estimated) on ICU admission in order to calculate the body mass index were included (n = 8,829). None. Underweight was defined as body mass index less than 18.5 kg/m, normal weight as body mass index 18.5-24.9 kg/m, overweight as body mass index 25-29.9 kg/m, obese as body mass index 30-39.9 kg/m, and morbidly obese as body mass index greater than or equal to 40 kg/m. The mean body mass index was 26.4 ± 6.5 kg/m. The ICU length of stay was similar among categories, but overweight and obese patients had longer hospital lengths of stay than patients with normal body mass index (10 [interquartile range, 5-21] and 11 [5-21] vs 9 [4-19] d; p < 0.01 pairwise). ICU mortality was lower in morbidly obese than in normal body mass index patients (11.2% vs 16.6%; p = 0.015). In-hospital mortality was lower in morbidly obese and overweight patients and higher in underweight patients than in those with normal body mass index. In a multilevel Cox proportional hazard analysis, underweight was independently associated with a higher hazard of 60-day in-hospital death (hazard ratio, 1.32; 95% CI, 1.05-1.65; p = 0.018), whereas overweight was associated with a lower hazard (hazard ratio, 0.79; 95% CI, 0.71-0.89; p < 0.001). No body mass index category was associated with an increased hazard of ICU-acquired infection. In this large cohort of critically ill patients, underweight was independently associated with a higher hazard of 60-day in-hospital death and overweight with a lower hazard. None of the body mass index categories as independently

Families of older adults are intricately involved in the end-of-life decision-making process for a family member with a serious illness in the intensive care unit (ICU) setting. However, families are not always as involved and as informed as they would like to be. Creating a culture that assesses family needs and supports families is an important component of family-centered care. There are several strategies that nurses and other members of the interdisciplinary team can use to promote family-centered end-of-life care in the ICU. Nurses can get to know the family by spending time talking with them, assessing them, seeking to understand their perspectives on their family member's condition, and discussing previously verbalized patient wishes for care. This article offers strategies nurses can use to help guide the family through the end-of-life decision-making process, support families as difficult and complex decisions are made in collaboration with the health care team, and prepare families for the dying process.

Purpose Community-acquired pneumonia (CAP) is the most common infection leading to hospitalization in the U.S. The objective of this study was to evaluate management practices for inpatient CAP in relation to IDSA/ATS guidelines to identify opportunities for antibiotic and health care resource stewardship. Methods This was a retrospective cohort study of adults hospitalized for CAP at a single institution from April 15, 2008 – May 31, 2009. Results Of 209 cases, 166 (79%) were admitted to a medical ward and 43 (21%) to the intensive care unit (ICU). 61 (29%) cases were candidates for outpatient therapy per IDSA/ATS guidance with a CURB-65 score of 0 or 1 and absence of hypoxemia. 110 sputum cultures were ordered; however, an evaluable sample was obtained in 49 (45%) cases, median time from antibiotic initiation to specimen collection was 11 (IQR 6–19) hours, and a potential pathogen was identified in only 18 (16%). Blood cultures were routinely obtained for both non-ICU (81%) and ICU (95%) cases, but 15 of 36 (42%) positive cultures were false-positive results. The most common antibiotic regimen was ceftriaxone plus azithromycin (182, 87% cases). Discordant with IDSA/ATS recommendations, oral step-down therapy consisted of a new antibiotic class in 120 (66%), most commonly levofloxacin (101, 55%). Treatment durations were typically longer than suggested with a median of 10 (IQR 8 – 12) days. Conclusions In this cohort of patients hospitalized for CAP, management was frequently inconsistent with IDSA/ATS guideline recommendations revealing potential targets to reduce unnecessary antibiotic and health care resource utilization.

Due to a gap between published clinical guidelines on status epilepticus SE and clinician management of SE, a systematic review was performed to investigate treatment adherence to SE guidelines and its impact on patient outcomes. Medline and Embase searches were conducted for studies appraising adherence to SE guidelines (from 1970 and 1st April 2018). The quality of eligible studies was assessed by QUADAS- 2 criteria. Comparison was made between patients where guidelines were followed and not followed. Various patient outcomes including intubation, ICU admission, morbidity and mortality were compared. A Forest plot was used to investigate the effect of adherence on outcome. A total of 3424 titles and abstracts were screened from the initial search after removal of duplicates. A total of 441 full text articles were reviewed in detail, and 22 articles were included in this study. The proportion of deviations ranged from 10.7% to 66.1%. Four studies were descriptive. Eighteen studies looked at the adverse effects of non-adherence. Eight studies showed respiratory depression and intubation were associated with excessive benzodiazepine use. A subset analysis showed 5.79 times higher odds of respiratory depression and intubation], if excessive benzodiazepines were given. The next most common variations were delayed management and insufficient treatment. These variations from the guidelines were associated with prolonged seizures. This review provides preliminary evidence that non-adherence to SE guidelines negatively impacts on patient outcomes. Appropriate and timely treatment is imperative for rapid seizure termination and improving outcomes. Copyright © 2018 British Epilepsy Association. All rights reserved.

Objective To determine whether the presence of Clinical Pharmacist affects the cost of drug therapy for patients admitted to the Intensive Care Unit (ICU) at Al-Hussein hospital at Royal Medical Services in Amman, Jordan. Method This study compares the consumed quantities of drugs over two periods of time. Each period was ten months long. In the second period there was a Clinical Pharmacist. The decrease in consumption rate of drugs is considered to be an indicator of the success of Clinical Pharmacist in the ICU, as any decrease in consumption rate reflects the correct application of Clinical Pharmacy practices. The cost of this decrease in consumption rate represents the total reduction of drug therapy cost. Results The total reduction of drug therapy cost after applying Clinical Pharmacy practices in the ICU over a period of ten months was 149946.80 JD (211574.90 USD), which represents an average saving of 35.8% when compared to the first period in this study. Conclusion The results of this study showed a significant reduction in the consumed quantities of drugs and therefore a reduction in cost of drug therapy. Such findings highlight the importance of the presence of Clinical Pharmacist in all Jordanian hospitals wards and units. PMID:24227956

To develop queuing and simulation-based models to understand the relationship between ICU bed availability and operating room schedule to maximize the use of critical care resources and minimize case cancellation while providing equity to patients and surgeons. Retrospective analysis of 6-month unit admission data from a cohort of cardiothoracic surgical patients, to create queuing and simulation-based models of ICU bed flow. Three different admission policies (current admission policy, shortest-processing-time policy, and a dynamic policy) were then analyzed using simulation models, representing 10 yr worth of potential admissions. Important output data consisted of the "average waiting time," a proxy for unit efficiency, and the "maximum waiting time," a surrogate for patient equity. A cardiothoracic surgical ICU in a tertiary center in New York, NY. Six hundred thirty consecutive cardiothoracic surgical patients admitted to the cardiothoracic surgical ICU. None. Although the shortest-processing-time admission policy performs best in terms of unit efficiency (0.4612 days), it did so at expense of patient equity prolonging surgical waiting time by as much as 21 days. The current policy gives the greatest equity but causes inefficiency in unit bed-flow (0.5033 days). The dynamic policy performs at a level (0.4997 days) 8.3% below that of the shortest-processing-time in average waiting time; however, it balances this with greater patient equity (maximum waiting time could be shortened by 4 days compared to the current policy). Queuing theory and computer simulation can be used to model case flow through a cardiothoracic operating room and ICU. A dynamic admission policy that looks at current waiting time and expected ICU length of stay allows for increased equity between patients with only minimum losses of efficiency. This dynamic admission policy would seem to be a superior in maximizing case-flow. These results may be generalized to other surgical ICUs.

Delirium affects nearly 70% of older adults hospitalized in the intensive care unit (ICU), and many of those will be left with persistent cognitive impairment or dementia. There are no effective and scalable recovery models to remediate ICU-acquired cognitive impairment and its attendant elevated risk for dementia or Alzheimer disease (AD). The Improving Recovery and Outcomes Every Day after the ICU (IMPROVE) trial is an ongoing clinical trial which evaluates the efficacy of a combined physical exercise and cognitive training on cognitive function among ICU survivors 50 years and older who experienced delirium during an ICU stay. This article describes the study protocol for IMPROVE. IMPROVE is a four-arm, randomized controlled trial. Subjects will be randomized to one of four arms: cognitive training and physical exercise; cognitive control and physical exercise; cognitive training and physical exercise control; and cognitive control and physical exercise control. Facilitators administer the physical exercise and exercise control interventions in individual and small group formats by using Internet-enabled videoconference. Cognitive training and control interventions are also facilitator led using Posit Science, Inc. online modules delivered in individual and small group format directly into the participants' homes. Subjects complete cognitive assessment, mood questionnaires, physical performance batteries, and quality of life scales at baseline, 3, and 6 months. Blood samples will also be taken at baseline and 3 months to measure pro-inflammatory cytokines and acute-phase reactants; neurotrophic factors; and markers of glial dysfunction and astrocyte activation. This study is the first clinical trial to examine the efficacy of combined physical and cognitive exercise on cognitive function in older ICU survivors with delirium. The results will provide information about potential synergistic effects of a combined intervention on a range of outcomes and mechanisms

Unplanned intensive care unit (ICU) transfer (UIT) within 48 hours of emergency department (ED) admission increases morbidity and mortality. We hypothesized that a majority of UITs do not have critical interventions (CrIs) and that CrI is associated with worse outcomes. The objective of the study is to characterize all UITs (including patients who died before ICU transfer), the proportion with CrI, and the effect of having CrI on mortality. This is a single-center, retrospective cohort study of UITs within 48 hours from 2008 to 2013 at an urban academic medical center and included patients 18 years or older without advanced directives (ADs). Critical intervention was defined by modified Delphi process. Data included demographics, comorbidities, reasons for UIT, length of stay, CrIs, and mortality. We calculated descriptive statistics with 95% confidence intervals (CIs). A total of 837 (0.76%) of 108 732 floor admissions from the ED had a UIT within 48 hours; 86 admitted patients died before ICU. We excluded 23 ADs, 117 postoperative transfers, 177 planned ICU transfers, and 4 with missing data. Of the 516 remaining, 65% (95% CI, 61%-69%) received a CrI. Unplanned ICU transfer reasons are as follows: 33 medical errors, 90 disease processes not present on arrival, and 393 clinical deteriorations. Mortality was 10.5% (95% CI, 8%-14%), and mean length of stay was 258 hours (95% CI, 233-283) for those with CrI, whereas the mortality was 2.8% (95% CI, 1%-6%) and mean length of stay was 177 hours (95% CI, 157-197) for those without CrI. Unplanned ICU transfer is rare, and only 65% had a CrI. Those with CrI had increased morbidity and mortality. Copyright © 2016 Elsevier Inc. All rights reserved.

Sepsis and septic shock continue to be syndromes that carry a high mortality rate worldwide. Early aggressive fluid and vasopressor support have resulted in significant improvement in patient outcomes. The prognostic clinical significance of a positive fluid balance in septic intensive care unit (ICU) patients remains undetermined. We collected data from 297 septic patients hospitalized in our general and medical ICUs at Soroka Medical Center between January 2005 and June 2011 and divided the 4 study groups into the following 4 fluid balances: group 1, patients with fluid balance at discharge from ICU (FBD) less than 10 L; group 2, patients with an FBD of 10 to 20 L; group 3, patients with an FBD of 20 to 30 L; and group 4, patients with FBD in excess of 30 L. The ICU and in-hospital mortality rate was also significantly higher in groups 2 to 4 as compared with group 1 (P < .001 for both ICU and in-hospital mortality). The positive cumulative FBD was found to be an independent predictor of ICU mortality (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.02-1.06; P < .001; Table 3) and in-hospital mortality (OR, 1.06; 95% CI, 1.03-1.08; P < .001; Table 5) and also to constitute a risk factor for new organ system dysfunction at hospital discharge (OR, 1.01; 95% CI, 1.01-1.013; P < .001; Table 6) in critically ill patients with severe sepsis/septic shock. Although it is a monocentric retrospective study, we suggest that positive cumulative fluid balance is one of the major factors that can predict the clinical outcome of critically ill patients during their ICU stay and after their discharge from the ICU.

The aim of this study was to investigate current mobilization practice, strength at ICU discharge and functional recovery at 6 months among mechanically ventilated ICU patients. This was a prospective, multi-centre, cohort study conducted in twelve ICUs in Australia and New Zealand. Patients were previously functionally independent and expected to be ventilated for >48 hours. We measured mobilization during invasive ventilation, sedation depth using the Richmond Agitation and Sedation Scale (RASS), co-interventions, duration of mechanical ventilation, ICU-acquired weakness (ICUAW) at ICU discharge, mortality at day 90, and 6-month functional recovery including return to work. We studied 192 patients (mean age 58.1 ± 15.8 years; mean Acute Physiology and Chronic Health Evaluation (APACHE) (IQR) II score, 18.0 (14 to 24)). Mortality at day 90 was 26.6% (51/192). Over 1,351 study days, we collected information during 1,288 planned early mobilization episodes in patients on mechanical ventilation for the first 14 days or until extubation (whichever occurred first). We recorded the highest level of early mobilization. Despite the presence of dedicated physical therapy staff, no mobilization occurred in 1,079 (84%) of these episodes. Where mobilization occurred, the maximum levels of mobilization were exercises in bed (N = 94, 7%), standing at the bed side (N = 11, 0.9%) or walking (N = 26, 2%). On day three, all patients who were mobilized were mechanically ventilated via an endotracheal tube (N = 10), whereas by day five 50% of the patients mobilized were mechanically ventilated via a tracheostomy tube (N = 18). Early mobilization of patients receiving mechanical ventilation was uncommon. More than 50% of patients discharged from the ICU had developed ICU-acquired weakness, which was associated with death between ICU discharge and day-90. ClinicalTrials.gov NCT01674608.

Flexible optical bronchoscopes are essential for management of airways in ICU, but the conventional reusable flexible scopes have three major drawbacks: high cost of repairs, need for decontamination, and possible transmission of infectious agents. The main objective of this study was to measure the cost of bronchoalveolar lavage (BAL) and percutaneous tracheostomy (PT) using reusable bronchoscopes and single-use bronchoscopes in an ICU of an university hospital. The secondary objective was to compare the satisfaction of healthcare professionals with reusable and single-use bronchoscopes. The study was performed between August 2009 and July 2014 in a 16-bed ICU. All BAL and PT procedures were performed by experienced healthcare professionals. Cost analysis was performed considering ICU and hospital organization. Healthcare professional satisfaction with single-use and reusable scopes was determined based on eight factors. Sensitivity analysis was performed by applying discount rates (0, 3, and 5%) and by simulation of six situations based on different assumptions. At a discount rate of 3%, the costs per BAL for the two reusable scopes were 188.86€ (scope 1) and 185.94€ (scope 2), and the costs per PT for the reusable scope 1 and scope 2 and single-use scopes were 1613.84€, 410.24€, and 204.49€, respectively. The cost per procedure for the reusable scopes depended on the number of procedures performed, maintenance costs, and decontamination costs. Healthcare professionals were more satisfied with the third-generation single-use Ambu ® aScope™. The cost per procedure for the single-use scope was not superior to that for reusable scopes. The choice of single-use or reusable bronchoscopes in an ICU should consider the frequency of procedures and the number of bronchoscopes needed.

Mitochondrial damage occurs in the acute phase of critical illness, followed by activation of mitochondrial biogenesis in survivors. It has been hypothesized that bioenergetics failure of skeletal muscle may contribute to the development of ICU-acquired weakness. The aim of the present study was to determine whether mitochondrial dysfunction persists until protracted phase of critical illness. In this single-centre controlled-cohort ex vivo proof-of-concept pilot study, we obtained vastus lateralis biopsies from ventilated patients with ICU-acquired weakness (n = 8) and from age and sex-matched metabolically healthy controls (n = 8). Mitochondrial functional indices were measured in cytosolic context by high-resolution respirometry in tissue homogenates, activities of respiratory complexes by spectrophotometry and individual functional capacities were correlated with concentrations of electron transport chain key subunits from respiratory complexes II, III, IV and V measured by western blot. The ability of aerobic ATP synthesis (OXPHOS) was reduced to ~54% in ICU patients (p<0.01), in correlation with the depletion of complexes III (~38% of control, p = 0.02) and IV (~26% of controls, p<0.01) and without signs of mitochondrial uncoupling. When mitochondrial functional indices were adjusted to citrate synthase activity, OXPHOS and the activity of complexes I and IV were not different, whilst the activities of complexes II and III were increased in ICU patients 3-fold (p<0.01) respectively 2-fold (p<0.01). Compared to healthy controls, in ICU patients we have demonstrated a ~50% reduction of the ability of skeletal muscle to synthetize ATP in mitochondria. We found a depletion of complex III and IV concentrations and relative increases in functional capacities of complex II and glycerol-3-phosphate dehydrogenase/complex III.

With increasing life expectancy and ICU admission of elderly patients, mechanical ventilation, and weaning trials have increased worldwide. We evaluated a cohort with 479 subjects in the ICU. Patients younger than 18 y, tracheostomized, or with neurologic diseases were excluded, resulting in 331 subjects. Subjects ≥70 y old were considered elderly, whereas those <70 y old were considered non-elderly. Besides the conventional weaning indexes, we evaluated the performance of the integrative weaning index (IWI). The probability of successful weaning was investigated using relative risk and logistic regression. The Hosmer-Lemeshow goodness-of-fit test was used to calibrate and the C statistic was calculated to evaluate the association between predicted probabilities and observed proportions in the logistic regression model. Prevalence of successful weaning in the sample was 83.7%. There was no difference in mortality between elderly and non-elderly subjects ( P = .16), in days of mechanical ventilation ( P = .22) and days of weaning ( P = .55). In elderly subjects, the IWI was the only respiratory variable associated with mechanical ventilation weaning in this population ( P < .001). The IWI was the independent variable found in weaning of elderly subjects that may contribute to the critical moment of this population in intensive care. Copyright © 2017 by Daedalus Enterprises.

The call for meaningful patient and family engagement in healthcare and research is gaining impetus. Healthcare institutions and research funding agencies increasingly encourage clinicians and researchers to work actively with patients and their families to advance clinical care and research. Engagement is increasingly mandated by healthcare organizations and is becoming a prerequisite for research funding. In this article, we review the rationale and the current state of patient and family engagement in patient care and research in the intensive care unit (ICU). We identify opportunities to strengthen engagement in patient care by promoting greater patient and family involvement in care delivery and supporting their participation in shared decision-making. We also identify challenges related to patient willingness to engage, barriers to participation, participant risks, and participant expectations. To advance engagement, clinicians and researchers can develop the science behind engagement in the ICU context and demonstrate its impact on patient and process-related outcomes. Additionally, we provide practical guidance on how to engage, highlight features of successful engagement strategies, and identify areas for future research. At present, enormous opportunities remain to enhance engagement across the continuum of ICU care and research.

Community-acquired pneumonia (CAP) is the most common infection leading to hospitalization in the USA. The objective of this study was to evaluate management practices for inpatient CAP in relation to Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) guidelines to identify opportunities for antibiotic and health care resource stewardship. This was a retrospective cohort study of adults hospitalized for CAP at a single institution from 15 April 2008 to 31 May 2009. Of the 209 patients with CAP who presented to Denver Health Medical Center during the study period and were hospitalized, 166 (79 %) and 43 (21 %) were admitted to a medical ward and the intensive care unit (ICU), respectively. Sixty-one (29 %) patients were candidates for outpatient therapy per IDSA/ATS guidance with a CURB-65 score of 0 or 1 and absence of hypoxemia. Sputum cultures were ordered for 110 specimens; however, an evaluable sample was obtained in only 49 (45 %) cases. Median time from antibiotic initiation to specimen collection was 11 [interquartile range (IQR) 6-19] h, and a potential pathogen was identified in only 18 (16 %) cultures. Blood cultures were routinely obtained for both non-ICU (81 %) and ICU (95 %) cases, but 15 of 36 (42 %) positive cultures were false-positive results. The most common antibiotic regimen was ceftriaxone + azithromycin (182, 87 % cases). Discordant with IDSA/ATS recommendations, oral step-down therapy consisted of a new antibiotic class in 120 (66 %), most commonly levofloxacin (101, 55 %). Treatment durations were typically longer than suggested with a median of 10 (IQR 8-12) days. In this cohort of patients hospitalized for CAP, management was frequently inconsistent with IDSA/ATS guideline recommendations, revealing potential targets to reduce unnecessary antibiotic and healthcare resource utilization.

The intensive care delirium screening checklist: translation and reliability testing in a Swedish ICU.

The view of delirium has changed considerably over the last decade, and delirium is now a very topical issue within the intensive care unit (ICU) setting. Delirium has proved to be common in critically ill patients and is manifested as acute changes in mental status with reduced cognitive ability, incoherent thought patterns, impaired consciousness, agitation and acute confusion. In order to be able to prevent, identify and alleviate problems related to delirium it is important that validated instruments for delirium screening are implemented and evaluated. The aim of this study was to translate the Intensive Care Delirium Screening Checklist (ICDSC) into Swedish and test the inter-rater reliability in a Swedish general ICU setting. The study was carried out during 2009 in a general Swedish ICU. A translation of the scale from English into Swedish was made, including back-translation, critical review and pilot testing. A total of 49 paired ratings were carried out using the Swedish version of the ICDSC scale. The inter-rater reliability was tested using weighted kappa (κ) statistics (linear weighting). The ICDSC scale was successfully translated into Swedish and the inter-rater reliability testing of the Swedish version resulted in a weighted k value of 0.92. The result of this study indicates that the Swedish version of the ICDSC scale has a very good inter-rater reliability. The high inter-rater reliability and the ease of administration make the ICDSC scale applicable for delirium screening in a Swedish ICU setting. © 2011 The Authors.

We evaluated the predictive ability of mechanism, Glasgow coma scale, age and arterial pressure (MGAP), Glasgow coma scale, age and systolic blood pressure (GAP), and triage-revised trauma Score (T-RTS) scores in patients from the Spanish trauma ICU registry using the trauma and injury severity score (TRISS) as a reference standard. Patients admitted for traumatic disease in the participating ICU were included. Quantitative data were reported as median [interquartile range (IQR), categorical data as number (percentage)]. Comparisons between groups with quantitative variables and categorical variables were performed using Student's T Test and Chi Square Test, respectively. We performed receiving operating curves (ROC) and evaluated the area under the curve (AUC) with its 95 % confidence interval (CI). Sensitivity, specificity, positive predictive and negative predictive values and accuracy were evaluated in all the scores. A value of p < 0.05 was considered significant. The final sample included 1361 trauma ICU patients. Median age was 45 (30-61) years. 1092 patients (80.3 %) were male. Median ISS was 18 (13-26) and median T-RTS was 11 (10-12). Median GAP was 20 (15-22) and median MGAP 24 (20-27). Observed mortality was 17.7 % whilst predicted mortality using TRISS was 16.9 %. The AUC in the scores evaluated was: TRISS 0.897 (95 % CI 0.876-0.918), MGAP 0.860 (95 % CI 0.835-0.886), GAP 0.849 (95 % CI 0.823-0.876) and T-RTS 0.796 (95 % CI 0.762-0.830). Both MGAP and GAP scores performed better than the T-RTS in the prediction of hospital mortality in Spanish trauma ICU patients. Since these are easy-to-perform scores, they should be incorporated in clinical practice as a triaging tool.

Data regarding patients admitted to the ICU Famema was obtained from the Technical Information Center (Núcleo Técnico de Informações, NTI, Famema). For data analysis, we used the distribution of absolute and relative frequencies with simple statistical treatment. 2,022 ICU admissions were recorded from June 2010 to July 2012 with 1,936 being coded according to the ICD-10. The epidemiological profile comprised mostly males (57.91%), predominantly seniors ≥ 60 years (48.89%), at an average age of 56.64 years (±19.18), with limited formal education (63.3% complete primary school), mostly white (77.10%), Catholic (75.12%), from the city of Marília, state of São Paulo, Brazil (53.81%). The average occupancy rate was 94.42%. The predominant cause of morbidity was diseases of the circulatory system with 494 admissions (25.5%), followed by traumas and external causes with 446 admissions (23.03%) and neoplasms with 213 admissions (11.00%). The average stay was 8.09 days (±10.73). The longest average stay was due to skin and subcutaneous tissue diseases, with average stay of 12.77 days (±17.07). There were 471 deaths (24.32%), mainly caused by diseases of the circulatory system (30.99%). The age group with the highest mortality was the range from 70 to 79 years with 102 deaths (21.65%). The ICU Famema presents an epidemiological profile similar to other intensive care units in Brazil and worldwide, despite the few studies available in the literature. Thus, we feel in tune with the treatment of critical care patients.

Organizational data such as bed occupancy rate and nurse-to-patient ratio are related to clinical outcomes and to the efficient use of intensive care unit (ICU) resources. Standards for these performance indicators are provided in guidelines. We studied the effects of a multifaceted feedback strategy to improve the adherence to these standards. In a cluster randomized controlled study design the intervention ICUs received extensive monthly feedback reports, they received outreach visits and initiated a quality improvement team. The control ICUs received limited quarterly feedback reports only. We collected primary data prospectively within the setting of a Dutch national ICU registry over a 14-month study period. The target indicators were bed occupancy rate (aiming at 80 % or below) and nurse-to-patient ratio (aiming at 0.5 or higher). Data were collected per 8-h nursing shift. Logistic regression analysis was performed. For both study end points, the odds ratios (OR) for improvements at follow-up versus at baseline were calculated separately for control and intervention ICUs. We analyzed data on 67,237 nursing shifts. The bed occupancy rate did not improve in the intervention group compared to baseline (adjusted OR 0.88; 95 % confidence interval (CI), 0.62-1.27) or compared to control group (OR 0.67; 95 % CI 0.39-1.15). The nurse-to-patient ratio did not improve (OR 0.72; 95 % CI 0.41-1.26 compared to baseline and OR 0.65; 95 % CI 0.35-1.19 compared to control group). A multifaceted feedback intervention did not improve the adherence to guideline-based standards on the organizational issues bed occupancy rate and nurse-to-patient ratio in the ICU. The reasons may be a limited confidence in data quality, the lack of practical tools for improvement, and the relatively short follow-up. ISRCTN50542146.

Successful and sustained integration of palliative care into the intensive care unit (ICU) requires the active engagement of bedside nurses. To describe the perspectives of ICU bedside nurses on their involvement in palliative care communication. A survey was designed, based on prior work, to assess nurses' perspectives on palliative care communication, including the importance and frequency of their involvement, confidence, and barriers. The 46-item survey was distributed via e-mail in 2013 to bedside nurses working in ICUs across the five academic medical centers of the University of California, U.S. The survey was sent to 1791 nurses; 598 (33%) responded. Most participants (88%) reported that their engagement in discussions of prognosis, goals of care, and palliative care was very important to the quality of patient care. A minority reported often discussing palliative care consultations with physicians (31%) or families (33%); 45% reported rarely or never participating in family meeting discussions. Participating nurses most frequently cited the following barriers to their involvement in palliative care communication: need for more training (66%), physicians not asking their perspective (60%), and the emotional toll of discussions (43%). ICU bedside nurses see their involvement in discussions of prognosis, goals of care, and palliative care as a key element of overall quality of patient care. Based on the barriers participants identified regarding their engagement, interventions are needed to ensure that nurses have the education, opportunities, and support to actively participate in these discussions.

To evaluate differences in the characteristics and outcomes of intensive care unit (ICU) patients over time. We reviewed all epidemiological data, including comorbidities, types and severity of organ failure, interventions, lengths of stay and outcome, for patients from the Sepsis Occurrence in Acutely ill Patients (SOAP) study, an observational study conducted in European intensive care units in 2002, and the Intensive Care Over Nations (ICON) audit, a survey of intensive care unit patients conducted in 2012. We compared the 3147 patients from the SOAP study with the 4852 patients from the ICON audit admitted to intensive care units in the same countries as those in the SOAP study. The ICON patients were older (62.5 ± 17.0 vs. 60.6 ± 17.4 years) and had higher severity scores than the SOAP patients. The proportion of patients with sepsis at any time during the intensive care unit stay was slightly higher in the ICON study (31.9 vs. 29.6%, p = 0.03). In multilevel analysis, the adjusted odds of ICU mortality were significantly lower for ICON patients than for SOAP patients, particularly in patients with sepsis [OR 0.45 (0.35-0.59), p < 0.001]. Over the 10-year period between 2002 and 2012, the proportion of patients with sepsis admitted to European ICUs remained relatively stable, but the severity of disease increased. In multilevel analysis, the odds of ICU mortality were lower in our 2012 cohort compared to our 2002 cohort, particularly in patients with sepsis.

The quality of care is a key aspect in the gene- ral hospital setting and particularly in ICU. The objective of this study was to analyze the assessment of ICU stay by patients and relatives, as well as the influence of socio-demographic/psycho- logical variables on this assessment. This study explores, conducting telephone surveys, the satisfaction71 critically ill patients and 89 relatives answered the Questionnaire of the ICU stay assessment and the Hospital Anxiety-Depression Scale. Descriptive and frequency analyzes were performed. Likewise, correlation coefficients (Pearson/ Spearman), Student's t test, ANOVA analysis and multiple re- gression equations were used. There were 4,486 hospital episodes, 1,108 due to complications of HCC, which generated 6,713 stays, readmission rate of 28.2% and mortality of 10.2%. The hospital cost amounted to 8,788,593EUR: 3,306,333EUR corresponded to Cirrhosis (5,273EUR/patient); 1,060,521EUR to Carcinoma (6,350EUR/ patient) and 2,962,873EUR to transplantation (70,544EUR/paciente. Comorbidity was 1,458,866EUR. These costs are maintai- ned for an average of 4 years once the cirrhosis decompensation begins. The general evaluation of the ICU stay was po- sitive, although with aspects susceptible to be improved. To know this reality is the prior step to the implementation of those measu- res that reinforce the well-valued issues and improve the worst- valued aspects in order to optimize the quality of the offered care.

Family members could play an important role in preventing and reducing the development of delirium in Intensive Care Units (ICU) patients. This study sought to assess the feasibility of design and recruitment, and acceptability for family members and nurses of a family delivered intervention to reduce delirium in ICU patients. A single centre randomised controlled trial in an Australian medical/surgical ICU was conducted. Sixty-one family members were randomised (29 in intervention and 32 in non-intervention group). Following instructions, the intervention comprised the family members providing orientation or memory clues (family photographs, orientation to surroundings) to their relative each day. In addition, family members conducted sensory checks (vision and hearing with glasses and hearing aids); and therapeutic or cognitive stimulation (discussing family life, reminiscing) daily. Eleven ICU nurses were interviewed to gain insight into the feasibility and acceptability of implementing the intervention from their perspective. Recruitment rate was 28% of eligible patients (recruited n=90, attrition n=1). Following instruction by the research nurse the family member delivered the intervention which was assessed to be feasible and acceptable by family members and nurses. Protocol adherence could be improved with alternative data collection methods. Nurses considered the activities acceptable. The study was able to recruit, randomise and retain family member participants. Further strategies are required to assess intervention fidelity and improve data collection.

Knowledge of patients' height is essential for daily practice in the intensive care unit. However, actual height measurements are unavailable on a daily routine in the ICU and measured height in the supine position and/or visual estimates may lack consistency. Clinicians do need simple and rapid methods to estimate the patients' height, especially in short height and/or obese patients. The objectives of the study were to evaluate several anthropometric formulas for height estimation on healthy volunteers and to test whether several of these estimates will help tidal volume setting in ICU patients. This was a prospective, observational study in a medical intensive care unit of a university hospital. During the first phase of the study, eight limb measurements were performed on 60 healthy volunteers and 18 height estimation formulas were tested. During the second phase, four height estimates were performed on 60 consecutive ICU patients under mechanical ventilation. In the 60 healthy volunteers, actual height was well correlated with the gold standard, measured height in the erect position. Correlation was low between actual and calculated height, using the hand's length and width, the index, or the foot equations. The Chumlea method and its simplified version, performed in the supine position, provided adequate estimates. In the 60 ICU patients, calculated height using the simplified Chumlea method was well correlated with measured height (r = 0.78; ∂ < 1 %). Ulna and tibia estimates also provided valuable estimates. All these height estimates allowed calculating IBW or PBW that were significantly different from the patients' actual weight on admission. In most cases, tidal volume set according to these estimates was lower than what would have been set using the actual weight. When actual height is unavailable in ICU patients undergoing mechanical ventilation, alternative anthropometric methods to obtain patient's height based on lower leg and on forearm

Accurate diagnosis for Arabic speaking critically ill patients suffering from delirium is limited by the need for a valid/reliable translation of a standardized delirium instrument such as the Confusion Assessment Method for the ICU (CAM-ICU). To determine the validity and reliability of the Arabic version of the CAM-ICU. A prospective cohort study design was used to conduct the current study. Data collection took place in Geriatric, Emergency and Surgical intensive care units. Fifty-eight adult patients met the inclusion criteria and participated in the study. Among the participants 22(38%) patients were on mechanical ventilation. After translating the CAM-ICU into Arabic language, the Arabic CAM-ICU was administered by two well-trained critical care nurses and compared with reference standard assessments by delirium experts using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM -IV-TR), along with assessment of severity of illness using Sequential Organ Failure Assessment (SOFA). Concurrent validity was assessed by calculating sensitivity, specificity and positive and negative predictive value (PPV and NPV) for the two Arabic CAM-ICU raters, where calculations were based on considering the DSM-IV-TR criterion as the reference standard. The convergent validity of the Arabic CAM-ICU was explored by comparing the Arabic CAM-ICU ratings and the total score of SOFA (severity of illness) and MMSE (cognitive impairment). A total of 58 ICU patients were included, of whom 27 (47%) were diagnosed with delirium during their ICU stay via DSM-IV criteria. Interrater reliability for the Arabic CAM-ICU, overall and for mechanically ventilated patients assessed using Cohen's kappa (κ) were 0.82 and 1, respectively, p < 0.001. The sensitivities (95% CI) for the two critical care nurses when using the Arabic CAM-ICU compared with the reference standard were 81% (60%-93%) and 85% (65%-95%), respectively, whereas specificity (95% CI

Patients' and family members' experiences of hospital care are important indicators of quality. "Black, Asian, and Hispanic patients are more at risk than White patients for decreased satisfaction with care." In addition, of any of these groups, Hispanic patients were most likely to report a lack of patient-centered care. In the intensive care setting, (ICU) previous research has indicated that the needs and satisfaction of family members of neurological ICU patients are different from those of family members of other types of ICU patients. The purpose of this study was to determine if there were any differences between English-speaking and Spanish-speaking family members of patients in a neurological ICU. This study was a single center prospective study conducted over a 10-month period from April 2013 to February 2014 in the 18-bed neuroscience ICU of a large, urban, academic medical center. The Family Satisfaction with ICU (FS-ICU) questionnaire was used; it provides an overall score and has two factors: satisfaction with care and satisfaction with decision-making. There was no statistical significance between the two groups in overall satisfaction or in satisfaction with care, however Spanish-speakers (n=22) were significantly less satisfied (p=.04) than English-speakers (n=50) with decision-making. There were three other discreet variables in which Spanish-speakers were also less satisfied: (a) management of patients' pain (OR 3.16, 95% CI [1.12, 8.9]) (b) management of patients' breathlessness (OR 3.5, 95% CI [1.23, 9.96]) as well as (c) ease of getting information (OR 3.25, 95% CI [1.09, 9.64]). Using a standardized survey it was found that Spanish-speakers were statistically less satisfied with decision-making than English-speakers. Additionally, Spanish-speakers were statistically less satisfied with management of patients' pain and breathlessness and ease of getting information. Based on these findings, increased vigilance is recommended regarding decision

Closing the Loop in ICU Decision Support: Physiologic Event Detection, Alerts, and Documentation

Automated physiologic event detection and alerting is a challenging task in the ICU. Ideally care providers should be alerted only when events are clinically significant and there is opportunity for corrective action. However, the concepts of clinical significance and opportunity are difficult to define in automated systems, and effectiveness of alerting algorithms is difficult to measure. This paper describes recent efforts on the Simon project to capture information from ICU care providers about patient state and therapy in response to alerts, in order to assess the value of event definitions and progressively refine alerting algorithms. Event definitions for intracranial pressure and cerebral perfusion pressure were studied by implementing a reliable system to automatically deliver alerts to clinical users’ alphanumeric pagers, and to capture associated documentation about patient state and therapy when the alerts occurred. During a 6-month test period in the trauma ICU at Vanderbilt University Medical Center, 530 alerts were detected in 2280 hours of data spanning 14 patients. Clinical users electronically documented 81% of these alerts as they occurred. Retrospectively classifying documentation based on therapeutic actions taken, or reasons why actions were not taken, provided useful information about ways to potentially improve event definitions and enhance system utility.

Objective To implement delirium monitoring, test reliability, and monitor compliance of performing the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) in trauma patients. Design and setting Prospective, observational study in a Level 1 trauma unit of a tertiary care, university-based medical center. Patients Acutely injured patients admitted to the trauma unit from February 1, 2006–April 16, 2006. Measurements and Results Following web-based teaching modules and group in-services, bedside nurses evaluated patients daily for depth of sedation with the Richmond Agitation-Sedation Scale (RASS) and for the presence of delirium with the CAM-ICU. On randomly assigned days over a 10-week period, evaluations by nursing staff were followed by evaluations by an expert evaluator of the RASS and the CAM-ICU, in order to assess compliance and reliability of the CAM-ICU in trauma patients. Following the audit period, the nurses completed a post-implementation survey. One thousand and eleven random CAM-ICU assessments were performed by the expert evaluator, within 1 hour of the bedside nurses’ assessments. Nurses completed the CAM-ICU assessments in 84% (849 of 1011) of evaluations. Overall agreement (κ) between nurses and the expert evaluator was 0.77 (0.721, 0.822; p<0.0001). In TBI patients κ was 0.75 (0.667, 0.829; p<0.0001), while in mechanically-ventilated patients κ was 0.62 (0.534, 0.704; p<0.0001). The survey revealed nurses were confident in performing the CAM-ICU, realized the importance of delirium, and were satisfied with the training they received. The survey also acknowledged obstacles to implementation including nursing time and failure of physicians/surgeons to address treatment approaches for delirium. Conclusions The CAM-ICU can be successfully implemented in a university-based trauma unit with high compliance and reliability. Quality improvement projects seeking to implement delirium monitoring would be wise to address potential

We sought to determine whether black patients admitted to an ICU were less likely than white patients to withdraw life-sustaining treatments. We performed a retrospective cohort study of hospital discharges from October 20, 2015, to October 19, 2016, for inpatients 18 years old or older and recorded those patients, along with their respective races, who had an "Adult Comfort Care" order set placed prior to discharge. A two-sample test for equality of two proportions with continuity correction was performed to compare the proportions between blacks and whites. University of Florida Health. The study cohort included 29,590 inpatient discharges, with 21,212 Caucasians (71.69%), 5,825 African Americans (19.69%), and 2,546 non-Caucasians/non-African Americans (8.62%). Withdrawal of life-sustaining treatments. Of the total discharges (n = 29,590), 525 (1.77%) had the Adult Comfort Care order set placed. Seventy-eight of 5,825 African American patients (1.34%) had the Adult Comfort Care order set placed, whereas 413 of 21,212 Caucasian patients (1.95%) had this order set placed (p = 0.00251; 95% CI, 0.00248-0.00968). Of the 29,590 patients evaluated, 6,324 patients (21.37%) spent at least one night in an ICU. Of these 6,324 patients, 4,821 (76.24%) were white and 1,056 (16.70%) were black. Three hundred fifty of 6,324 (5.53%) were discharged with an Adult Comfort Care order set. Two hundred seventy-one White patients (5.62%) with one night in an ICU were discharged with an Adult Comfort Care order set, whereas 54 Black patients (5.11%) with one night in an ICU had the order set (p = 0.516). This study suggests that Black patients may be less likely to withdraw life-supportive measures than whites, but that this disparity may be absent in patients who spend time in the ICU during their hospitalization.

Neuro-, Trauma -, or Med/Surg-ICU: Does it matter where polytrauma patients with TBI are admitted? Secondary analysis of AAST-MITC decompressive craniectomy study

Introduction Patients with non-traumatic acute intracranial pathology benefit from neurointensivist care. Similarly, trauma patients with and without TBI fare better when treated by a dedicated trauma team. No study has yet evaluated the role of specialized neurocritical (NICU) and trauma intensive care units (TICU) in the management of TBI patients, and it remains unclear which TBI patients are best served in NICU, TICU, or general (Med/Surg) ICU. Methods This study is a secondary analysis of The American Association for the Surgery of Trauma Multi-Institutional Trials Committee (AAST-MITC) decompressive craniectomy study. Twelve Level 1 trauma centers provided clinical data and head CT scans of patients with Glasgow Coma Scale (GCS) ≤13 and CT evidence of TBI. Non-ICU admissions were excluded. Multivariate logistic regression was performed to measure the association between ICU-type and survival and calculate the probability of death for increasing ISS. Polytrauma patients (ISS > 15) with TBI and isolated TBI patients (other AIS < 3) were analyzed separately. Results There were 3641 patients with CT evidence of TBI with 2951 admitted to an ICU. Prior to adjustment, patient demographics, injury severity, and survival differed significantly by unit type. After adjustment, unit-type, age and ISS remained independent predictors of death. Unit-type modified the effect of ISS on mortality. TBI-polytrauma patients admitted to a TICU had improved survival across increasing ISS (Fig1). Survival for isolated TBI patients was similar between TICU and NICU. Med/Surg ICU carried the greatest probability of death. Conclusion Polytrauma patients with TBI have lower mortality risk when admitted to a Trauma ICU. This survival benefit increases with increasing injury severity. Isolated TBI patients have similar mortality risk when admitted to a Neuro ICU compared to a Trauma ICU. Med/Surg ICU admission carries the highest mortality risk. PMID:28225527

Predicting ICU mortality: a comparison of stationary and nonstationary temporal models.

OBJECTIVE: This study evaluates the effectiveness of the stationarity assumption in predicting the mortality of intensive care unit (ICU) patients at the ICU discharge. DESIGN: This is a comparative study. A stationary temporal Bayesian network learned from data was compared to a set of (33) nonstationary temporal Bayesian networks learned from data. A process observed as a sequence of events is stationary if its stochastic properties stay the same when the sequence is shifted in a positive or negative direction by a constant time parameter. The temporal Bayesian networks forecast mortalities of patients, where each patient has one record per day. The predictive performance of the stationary model is compared with nonstationary models using the area under the receiver operating characteristics (ROC) curves. RESULTS: The stationary model usually performed best. However, one nonstationary model using large data sets performed significantly better than the stationary model. CONCLUSION: Results suggest that using a combination of stationary and nonstationary models may predict better than using either alone. PMID:11079917

Early mobilisation is advocated to improve recovery of intensive care unit (ICU) survivors. However, severe weakness in combination with tubes, lines and machinery are practical barriers for the implementation of ambulation with critically ill patients. The aim of this study was to explore the feasibility of Body Weight-Supported Treadmill Training (BWSTT) in critically ill patients in the ICU. A custom build bedside Body Weight-Supported Treadmill was used and evaluated in medical and surgical patients in the ICU. Feasibility was evaluated according to eligibility, successful number of BWSTT, number of staff needed, adverse events, number of patients that could not have walked without BWSTT, patient satisfaction and anxiety. Twenty participants, underwent 54 sessions BWSTT. Two staff members executed the BWSTT and no adverse events occurred. Medical equipment did not have to be disconnected during all treatment sessions. In 74% of the sessions, the participants would not have been able to walk without the BWSTT. Patient satisfaction with BWSTT was high and anxiety low. This proof of concept study demonstrated that BWSTT is safe, reduces staff resource, and facilitates the first time to ambulation in critically ill patients with severe muscle weakness in the ICU.

To determine the impact of introducing a two-tier system for responding to deteriorating ward patients on ICU admissions after medical emergency team review. Retrospective database review before (2006-2009) and after (2011-2013) the introduction of a two-tier system. Tertiary, university-affiliated hospital. A total of 1,564 ICU admissions. Two-tier rapid response system. The median number of medical emergency team activations/1,000 hospitalizations increased from 22 to 31 (difference [95% CI], 9 [5-10]; p<0.0001) with a decreased rate of medical emergency team activations leading to ICU admission (from median 11 to 8; difference [95% CI], 3 [3-4]; p=0.03). The median proportion of medical emergency team reviews leading to ICU admission increased for those triggered by tachypnoea (from 11% to 15%; difference [95% CI], 4 [3-5]; p<0.0001) and by hypotension (from 27% to 43%; difference [95% CI], 15 [12-19]; p<0.0001) and decreased for those triggered by reduced level of consciousness (from 20% to 17%; difference [95% CI], 3 [2-4]; p<0.0001) and by clinical concern (from 18% to 9%; difference [95% CI], 10 [9-13]; p<0.0001). The proportions of ICU admissions following medical emergency team review did not change significantly for tachycardia, seizure, or cardiorespiratory arrest. The overall ICU mortality for admissions following medical emergency team review for tachypnoea, tachycardia, and clinical concern decreased (from 29% to 9%: difference [95% CI], 20 [11-29]; p<0.0001) but did not change for the other triggers. The Acute Physiology and Chronic Health Evaluation predicted and observed ICU mortality and the proportion of patients dying with a not-for-resuscitation order decreased. The introduction of a two-tier response to clinical deterioration increased ICU admissions triggered by cardiorespiratory criteria, whereas admissions triggered by more subjective criteria decreased.

Objective To increase hand sanitizer usage among healthcare workers by developing and implementing a low-cost intervention using RFID and wireless mesh networks to provide real-time alarms for increasing hand hygiene compliance during opportune moments in an open layout Intensive Care Unit (ICU). Method A wireless, RFID based system was developed and deployed in the ICU. The ICU beds were divded into an intervention arm (n=10) and a control arm (n=14). Passive RFID tags were issued to the doctors, nurses and support staff of the ICU. Long range RFID readers were positioned strategically.

The aim of this study is to increase hand sanitizer usage among healthcare workers by developing and implementing a low-cost intervention using RFID and wireless mesh networks to provide real-time alarms for increasing hand hygiene compliance during opportune moments in an open layout Intensive Care Unit (ICU). A wireless, RFID based system was developed and implemented in the ICU. The ICU beds were divded into an intervention arm (n = 10) and a control arm (n = 14). Passive RFID tags were issued to the doctors, nurses and support staff of the ICU. Long range RFID readers were positioned strategically. Sensors were placed beneath the hand sanitizers to record sanitizer usage. The system would alert the HCWs by flashing a light if an opportune moment for hand sanitization was detected. A significant increase in hand sanitizer use was noted in the intervention arm. Usage was highest during the early part of the workday and decreased as the day progressed. Hand wash events per person hour was highest among the ancilliary staff followed by the doctors and nurses. Real-time feedback has potential to increase hand hygiene compliance among HCWs. The system demonstrates the possibility of automating compliance monitoring in an ICU with an open layout.

Background: Delirium evaluation in patients in the ICU requires the use of an arousal/sedation assessment tool prior to assessing consciousness. The Richmond Agitation-Sedation Scale (RASS) and the Riker Sedation-Agitation Scale (SAS) are well-validated arousal/sedation tools. We sought to assess the concordance of RASS and SAS assessments in determining eligibility of patients in the ICU for delirium screening using the confusion assessment method for the ICU (CAM-ICU). Methods: We performed a prospective cohort study in the adult medical, surgical, and progressive (step-down) ICUs of a tertiary care, university-affiliated, urban hospital in Indianapolis, Indiana. The cohort included 975 admissions to the ICU between January and October 2009. Results: The outcome measures of interest were the correlation and agreement between RASS and SAS measurements. In 2,469 RASS and SAS paired screens, the rank correlation using the Spearman correlation coefficient was 0.91, and the agreement between the two screening tools for assessing CAM-ICU eligibility as estimated by the κ coefficient was 0.93. Analysis showed that 70.1% of screens were eligible for CAM-ICU assessment using RASS (7.1% sedated [RASS −3 to −1]; 62.6% calm [0]; and 0.4% restless, agitated [+1 to +3]), compared with 72.1% using SAS (5% sedated [SAS 3]; 66.5% calm [4]; and 0.6% anxious, agitated [5, 6]). In the mechanically ventilated subgroup, RASS identified 19.1% CAM-ICU eligible patients compared with 24.6% by SAS. The correlation coefficient in this subgroup was 0.70 and the agreement was 0.81. Conclusion: Both SAS and RASS led to similar rates of delirium assessment using the CAM-ICU. PMID:22539644

Background The objective of this study was to evaluate the factors predictive of 28-day mortality and admission to Intensive Care Unit (ICU) in patients with ANCA-related pulmonary vasculitis. Methods We reviewed the medical records and imaging studies of 65 patients diagnosed with ANCA-related vasculitis hospitalized with pulmonary complications between February 1985 and November 2002. All patients underwent open or video-assisted thoracoscopic lung biopsy, had a positive ANCA serology, and were negative for glomerular basement membrane antibodies. Results At presentation, 72% had dyspnea, 68% fever, 47% cough, 45% elevated blood pressure, 32.3% hemoptysis, 26.1% sinus involvement, 15% renal failure, and 4.6% scleritis. Pathological findings included alveolar hemorrhage (60%), granulomatous inflammation (46%), and capillaritis (38%). A significant number required mechanical ventilation (27.7%), hemodialysis (24.6%), continuous renal replacement therapy (3.1%), and plasmapheresis (3.1%). The 28-day mortality was 16.9% (11/65). Mechanical ventilation (OR 68, P < 0.005), admission to ICU (OR 18.5, P < 0.01), and blood transfusion (OR 22.4, P < 0.004) were strong predictors of increased mortality within 28 days after admission. Respiratory failure (OR 31, P < 0.0007), hemoptysis (OR 2.9, P < 0.06), smoking (OR 5.9, P < 0.02), and acute renal failure (OR 7.8, P < 0.01) were also predictors for admission to the ICU. Conclusion In patients with ANCA-related pulmonary vasculitis several clinical factors, but not pathologic findings or ANCA titers, are associated with ICU admission and/or 28-day mortality.

Urine output (UO) is routinely measured in the intensive care unit (ICU) but its prognostic value remains debated. The study aimed to investigate the association between day 1 UO and hospital mortality. Clinical data were abstracted from the Multiparameter Intelligent Monitoring in Intensive Care II (version 2.6) database. UO was recorded for the first 24 h after ICU entry, and was classified into three categories: UO >0.5, 0.3-0.5 and ≤0.3 ml/kg per hour. The primary endpoint was the hospital mortality. Four models were built to adjust for the hazards ratio of mortality. A total of 21,207 unselected ICU patients including 2,401 non-survivors and 18,806 survivors were included (mortality rate 11.3 %). Mortality rate increased progressively across UO categories: >0.5 (7.67 %), 0.3-0.5 (11.27 %) and ≤0.3 ml/kg/h (18.29 %), and this relationship remained statistically significant after rigorous control of confounding factors with the Cox proportional hazards regression model. With UO >0.5 as the referent group, the hazards ratios for UO 0.3-0.5 and UO ≤0.3 were 1.41 (95 % CI 1.29-1.54) and 1.52 (95 % CI 1.38-1.67), respectively. UO obtained on ICU entry is an independent predictor of mortality irrespective of diuretic use. It would be interesting to examine whether strategies to increase UO would improve clinical outcome.

ICU-acquired candidemia within selective digestive decontamination studies: a meta-analysis.

Hurley, James C

2015-11-01

To estimate the direct and indirect (contextual) effects of the factorized constituents of selective digestive decontamination and selective oropharyngeal decontamination (SDD/SOD), being topical antibiotic (TA) and protocolized antifungal prophylaxis (PAFP), on ICU-acquired candidemia. A broad range of ICU candidemia incidence studies were sourced to serve as points of reference. The candidemia incidence was extracted from component (control and intervention) groups decanted from studies of various designs (concurrent or non-concurrent) and whether investigating SDD/SOD versus non-TA methods of ICU infection prevention. The candidemia incidences were summarized in regression models using generalized estimating equation (GEE) methods. Groups derived from observational studies (no prevention method under study) provided an overarching external benchmark candidemia incidence for calibration. Within studies investigating SDD/SOD, the mean (and 95% confidence interval) candidemia incidence among concurrent component groups (40 control; 2.4%; 1.7-3.2% and 43 intervention groups; 2.4%; 1.6-3.1%), but not non-concurrent control groups (11 groups; 1.6%; 0.1-2.7%), is higher than that of the benchmark candidemia incidence derived from 54 observational groups (1.5%; 1.2-1.9%). The TA constituent within SDD/SOD has significant direct and indirect (contextual) effects in GEE models even after adjusting for the publication year and the group-wide presence of either candidemia risk factors or PAFP use. The TA constituent of SDD/SOD is associated with a contextual effect on candidemia incidence which is similar in magnitude to that of the conventional candidemia risk factors and against which PAFP partially attenuates. This increase is inapparent within individual SDD/SOD studies examined in isolation.

In 2010, under the guidance of the DGAI (German Society of Anaesthesiology and Intensive Care Medicine) and DIVI (German Interdisciplinary Association for Intensive Care and Emergency Medicine), twelve German medical societies published the "Evidence- and Consensus-based Guidelines on the Management of Analgesia, Sedation and Delirium in Intensive Care". Since then, several new studies and publications have considerably increased the body of evidence, including the new recommendations from the American College of Critical Care Medicine (ACCM) in conjunction with Society of Critical Care Medicine (SCCM) and American Society of Health-System Pharmacists (ASHP) from 2013. For this update, a major restructuring and extension of the guidelines were needed in order to cover new aspects of treatment, such as sleep and anxiety management. The literature was systematically searched and evaluated using the criteria of the Oxford Center of Evidence Based Medicine. The body of evidence used to formulate these recommendations was reviewed and approved by representatives of 17 national societies. Three grades of recommendation were used as follows: Grade "A" (strong recommendation), Grade "B" (recommendation) and Grade "0" (open recommendation). The result is a comprehensive, interdisciplinary, evidence and consensus-based set of level 3 guidelines. This publication was designed for all ICU professionals, and takes into account all critically ill patient populations. It represents a guide to symptom-oriented prevention, diagnosis, and treatment of delirium, anxiety, stress, and protocol-based analgesia, sedation, and sleep-management in intensive care medicine.

To develop and validate an abbreviated version of the Cognitive Failure Questionnaire that can be used by patients as part of self-assessment to measure functional cognitive outcome in ICU survivors. A retrospective multicenter observational study. The ICUs of two Dutch university hospitals. Adult ICU survivors. None. Cognitive functioning was evaluated between 12 and 24 months after ICU discharge using the full 25-item Cognitive Failure Questionnaire (CFQ-25). Incomplete CFQ-25 questionnaires were excluded from analysis. Forward selection in a linear regression model was used in hospital A to assess which of the CFQ-25 items should be included to prevent a significant loss of correlation between an abbreviated and the full CFQ-25. Subsequently, the performance of an abbreviated Cognitive Failure Questionnaire was determined in hospital B using Pearson's correlation. A Bland-Altman plot was used to examine whether the reduced-item outcome scores of an abbreviated Cognitive Failure Questionnaire were a replacement for the full CFQ-25 outcome scores. Among 1,934 ICU survivors, 1,737 were included, 819 in hospital A, 918 in hospital B. The Pearson's correlation between the abbreviated 14-item Cognitive Failure Questionnaire (CFQ-14) and the CFQ-25 was 0.99. The mean of the difference scores was -0.26, and 95% of the difference scores fell within +5 and -5.5 on a 100-point maximum score. It is feasible to use the abbreviated CFQ-14 to measure self-reported cognitive failure in ICU survivors as this questionnaire has a similar performance as the full CFQ-25.

The aim of the study was to investigate the frequency and outcome of prolonged intensive care unit (ICU) length of stay (LOS) after abdominal aortic aneurysm (AAA) repair in the endovascular era. All patients operated on for AAA between 1999 and 2013 at Uppsala University hospital were identified. Data were retrieved from the Swedish Vascular registry, the Swedish Intensive Care registry, the National Population registry, and case records. Prolonged ICU LOS was defined as ≥ 48 h during the primary hospital stay. Patients surviving ≥ 48 h after AAA surgery were included in the analysis. A total of 725 patients were identified, of whom 707 (97.5%) survived ≥ 48 h; 563 (79.6%) underwent intact AAA repair and 144 (20.4%) ruptured AAA repair. A total of 548 patients (77.5%) required < 48 h of intensive care, 115 (16.3%) 2-6 days and 44 (6.2%) ≥ 7 days. The rate of prolonged ICU LOS declined considerably over time, from 41.4% of all AAA repairs in 1999 to 7.3% in 2013 (p < .001) whereas the use of endovascular aortic repair (EVAR) increased from 6.9% in 1999 to 78.0% in 2013 (p < .001). The 30 day survival rate was 98.2% for those with < 48 h ICU stay versus 93.0% for 2-6 days versus 81.8% for ≥ 7 days (p < .001); the corresponding 90 day survival was 97.1% versus 86.1% versus 63.6% (p < .001) respectively. For patients surviving 90 days after repair, there was no difference in long-term survival between the groups. During the period of progressively increasing use of EVAR, a simultaneous significant reduction in frequency of prolonged ICU LOS occurred. Although prolonged ICU LOS was associated with a high short-term mortality, long-term outcome among those surviving the initial 90 days was less affected.

Background: Formal family meetings have been recommended as a useful approach to assist in goal setting, facilitate decision making, and reduce use of ineffective resources in the ICU. We examined patient outcomes before and after implementation of an intensive communication system (ICS) to test the effect of regular, structured formal family meetings on patient outcomes among long-stay ICU patients. Methods: One hundred thirty-five patients receiving usual care and communication were enrolled as the control group, followed by enrollment of intervention patients (n = 346), from five ICUs. The ICS included a family meeting within 5 days of ICU admission and weekly thereafter. Each meeting discussed medical update, values and preferences, and goals of care; treatment plan; and milestones for judging effectiveness of treatment. Results: Using multivariate analysis, there were no significant differences between control and intervention patients in length of stay (LOS), the primary end point. Similarly, there were no significant differences in indicators of aggressiveness of care or treatment limitation decisions (ICU mortality, LOS, duration of ventilation, treatment limitation orders, or use of tracheostomy or percutaneous gastrostomy). Exploratory analysis suggested that in the medical ICUs, the intervention was associated with a lower prevalence of tracheostomy among patients who died or had do-not-attempt-resuscitation orders in place. Conclusions: The negative findings of the main analysis, in combination with preliminary evidence of differences among types of unit, suggest that further examination of the influence of patient, family, and unit characteristics on the effects of a system of regular family meetings may be warranted. Despite the lack of influence on patient outcomes, structured family meetings may be an effective approach to meeting information and support needs.

There are hardly any data about the incidence, risk factors and outcomes of ICU-associated A.baumannii colonisation/infection in HIV-infected and uninfected persons from resource-poor settings like Africa. We reviewed the case records of patients with A.baumannii colonisation/infection admitted into the adult respiratory and surgical ICUs in Cape Town, South Africa, from January 1 to December 31 2008. In contrast to colonisation, infection was defined as isolation of A.baumannii from any biological site in conjunction with a compatible clinical picture warranting treatment with antibiotics effective against A.baumannii. The incidence of A.baumannii colonisation/infection in 268 patients was 15 per 100 person-years, with an in-ICU mortality of 26.5 per 100 person-years. The average length of stay in ICU was 15 days (range 1-150). A.baumannii was most commonly isolated from the respiratory tract followed by the bloodstream. Independent predictors of mortality included older age (p = 0.02), low CD4 count if HIV-infected (p = 0.038), surgical intervention (p = 0.047), co-morbid Gram-negative sepsis (p = 0.01), high APACHE-II score (p = 0.001), multi-organ dysfunction syndrome (p = 0.012), and a positive blood culture for A.baumannii (p = 0.017). Of 21 A.baumannii colonised/infected HIV-positive persons those with clinical AIDS (CD4<200 cells/mm(3)) had significantly higher in-ICU mortality and were more likely to have a positive blood culture. Conclusion In this resource-poor setting A.baumannii infection in critically ill patients is common and associated with high mortality. HIV co-infected patients with advanced immunosuppression are at higher risk of death.

Mechanically ventilated critically ill patients receive significant amounts of sedatives and analgesics that increase their risk of developing coma and delirium. We evaluated the impact of a "Wake-up and Breathe Protocol" at our local ICU on sedation and delirium. A pre/post implementation study design. A 22-bed mixed surgical and medical ICU. Seven hundred two consecutive mechanically ventilated ICU patients from June 2010 to January 2013. Implementation of daily paired spontaneous awakening trials (daily sedation vacation plus spontaneous breathing trials) as a quality improvement project. After implementation of our program, there was an increase in the mean Richmond Agitation Sedation Scale scores on weekdays of 0.88 (p < 0.0001) and an increase in the mean Richmond Agitation Sedation Scale scores on weekends of 1.21 (p < 0.0001). After adjusting for age, race, gender, severity of illness, primary diagnosis, and ICU, the incidence and prevalence of delirium did not change post implementation of the protocol (incidence: 23% pre vs 19.6% post; p = 0.40; prevalence: 66.7% pre vs 55.3% post; p = 0.06). The combined prevalence of delirium/coma decreased from 90.8% pre protocol implementation to 85% postimplementation (odds ratio, 0.505; 95% CI, 0.299-0.853; p = 0.01). Implementing a "Wake Up and Breathe Program" resulted in reduced sedation among critically ill mechanically ventilated patients but did not change the incidence or prevalence of delirium.

During the 2009 influenza pandemic, several reports were published, nevertheless, data on the clinical profiles of critically ill patients with the new virus infection during this second outbreak are still lacking. Prospective, observational, multi-center study conducted in 148 Spanish intensive care units (ICU) during epidemiological weeks 50-52 of 2010 and weeks 1 - 4 of 2011. Three hundred patients admitted to an intensive care unit (ICU) with confirmed An/H1N1 infection were analyzed. The median age was 49 years [IQR=38-58] and 62% were male. The mean APACHE II score was 16.9 ± 7.5 and the mean SOFA score was 6.3 ± 3.5 on admission. Comorbidities were present in 76% (n=228) of cases and 111 (37.4%) patients were reportedly obese and 59 (20%) were COPD. The main presentation was viral pneumonia with severe hypoxemia in 65.7% (n=197) of the patients whereas co-infection was identified in 54 (18%) patients. All patients received antiviral treatment and initiated empirically in 194 patients (65.3%), however only 53 patients (17.6%) received early antiviral treatment. Vaccination was only administered in 22 (7.3%) patients. Sixty-seven of 200 patients with ICU discharge died. Haematological disease, severity of illness, infiltrates in chest X-ray and need for mechanical ventilation were variables independently associated with ICU mortality. In patients admitted to the ICU in the post-pandemic seasonal influenza outbreak vaccination was poorly implemented and appear to have higher frequency of severe comorbidities, severity of illness, incidence of primary viral pneumonia and increased mortality when compared with those observed in the 2009 pandemic outbreak.

Objective: The purpose of our study was to examine in patients hospitalized with community-acquired pneumonia (CAP) the association between abnormal Paco2 and ICU admission and 30-day mortality. Methods: A retrospective cohort study was conducted at two tertiary teaching hospitals. Eligible subjects were admitted with a diagnosis of CAP. Arterial blood gas analyses were obtained with measurement of Paco2 on admission. Multivariate analyses were performed using 30-day mortality and ICU admission as the dependent measures. Results: Data were abstracted on 453 subjects with a documented arterial blood gas analysis. One hundred eighty-nine patients (41%) had normal Paco2 (35-45 mm Hg), 194 patients (42%) had a Paco2 < 35 mm Hg (hypocapnic), and 70 patients (15%) had a Paco2 > 45 mm Hg (hypercapnic). In the multivariate analysis, after adjusting for severity of illness, hypocapnic patients had greater 30-day mortality (OR = 2.84; 95% CI, 1.28-6.30) and a higher need for ICU admission (OR = 2.88; 95% CI, 1.68-4.95) compared with patients with normal Paco2. In addition, hypercapnic patients had a greater 30-day mortality (OR = 3.38; 95% CI, 1.38-8.30) and a higher need for ICU admission (OR = 5.35; 95% CI, 2.80-10.23). When patients with COPD were excluded from the analysis, the differences persisted between groups. Conclusion: In hospitalized patients with CAP, both hypocapnia and hypercapnia were associated with an increased need for ICU admission and higher 30-day mortality. These findings persisted after excluding patients with CAP and with COPD. Therefore, Paco2 should be considered for inclusion in future severity stratification criteria to appropriate identified patients who will require a higher level of care and are at risk for increased mortality.

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.

Process Reengineering for Quality Improvement in ICU Based on Taylor's Management Theory.

Using methods including questionnaire-based surveys and control analysis, we analyzed the improvements in the efficiency of ICU rescue, service quality, and patients' satisfaction, in Xuzhou Central Hospital after the implementation of fine management, with an attempt to further introduce the concept of fine management and implement the brand construction. Originating in Taylor's "Theory of Scientific Management" (1982), fine management uses programmed, standardized, digitalized, and informational approaches to ensure each unit of an organization is running with great accuracy, high efficiency, strong coordination, and at sustained duration (Wang et al., Fine Management, 2007). The nature of fine management is a process that breaks up the strategy and goal, and executes it. Strategic planning takes place at every part of the process. Fine management demonstrates that everybody has a role to play in the management process, every area must be examined through the management process, and everything has to be managed (Zhang et al., The Experience of Hospital Nursing Precise Management, 2006). In other words, this kind of management theory demands all people to be involved in the entire process (Liu and Chen, Med Inf, 2007). As public hospital reform is becoming more widespread, it becomes imperative to "build a unified and efficient public hospital management system" and "improve the quality of medical services" (Guidelines on the Pilot Reform of Public Hospitals, 2010). The execution of fine management is of importance in optimizing the medical process, improving medical services and building a prestigious hospital brand.

To investigate the role of a dedicated service corridor in intensive care unit (ICU) noise control and staff stress and satisfaction. Shared corridors immediately adjacent to patient rooms are generally noisy due to a variety of activities, including service deliveries and pickups. The strategy of providing a dedicated service corridor is thought to reduce noise for patient care, but the extent to which it actually contributes to noise reduction in the patient care environment and in turn improves staff performance has not been previously documented. A before-and-after comparison was conducted in an adult cardiac ICU. The ICU was relocated from a traditional hospital environment to a new addition with a dedicated service corridor. A total of 118 nursing staff participated in the surveys regarding pre-move and post-move environmental comfort, stress, and satisfaction in the previous and new units. Acoustical measures of noise within the new ICU and a control environment of the previous unit were collected during four work days, along with on-site observations of corridor traffic. Independent and paired sample t-tests of survey data showed that the perceived noise level was lower and staff reported less stress and more satisfaction in the new ICU (p < 0.01). Analyses of acoustical data confirmed that the new ICU was significantly quieter (p < 0.02). Observations revealed how the service corridor impacted patient care services and traffic. The addition of a dedicated service corridor works in the new unit for improving noise control and staff stress and satisfaction.

Ventilator-associated pneumonia and ICU mortality in severe ARDS patients ventilated according to a lung-protective strategy

PubMed Central

2012-01-01

Introduction Ventilator-associated pneumonia (VAP) may contribute to the mortality associated with acute respiratory distress syndrome (ARDS). We aimed to determine the incidence, outcome, and risk factors of bacterial VAP complicating severe ARDS in patients ventilated by using a strictly standardized lung-protective strategy. Methods This prospective epidemiologic study was done in all the 339 patients with severe ARDS included in a multicenter randomized, placebo-controlled double-blind trial of cisatracurium besylate in severe ARDS patients. Patients with suspected VAP underwent bronchoalveolar lavage to confirm the diagnosis. Results Ninety-eight (28.9%) patients had at least one episode of microbiologically documented bacterial VAP, including 41 (41.8%) who died in the ICU, compared with 74 (30.7%) of the 241 patients without VAP (P = 0.05). After adjustment, age and severity at baseline, but not VAP, were associated with ICU death. Cisatracurium besylate therapy within 2 days of ARDS onset decreased the risk of ICU death. Factors independently associated with an increased risk to develop a VAP were male sex and worse admission Glasgow Coma Scale score. Tracheostomy, enteral nutrition, and the use of a subglottic secretion-drainage device were protective. Conclusions In patients with severe ARDS receiving lung-protective ventilation, VAP was associated with an increased crude ICU mortality which did not remain significant after adjustment.

Introduction Long-term outcomes of elderly patients after medical ICU care are little known. The aim of the study was to evaluate functional status and quality of life of elderly patients 12 months after discharge from a medical ICU. Methods We prospectively studied 112/230 healthy elderly patients (≥65 years surviving at least 12 months after ICU discharge) with full functional autonomy without cognitive impairment prior to ICU entry. The main diagnoses at admission using the Acute Physiology and Chronic Health Evaluation III (APACHE III) classification diagnosis and length of ICU stay and ICU scores (APACHE II, Sepsis-related Organ Failure Assessment (SOFA) and OMEGA) at admission and discharge were collected. Comprehensive geriatric assessment included the presence of the main geriatric syndromes and the application of Lawton, Barthel, and Charlson Indexes and Informant Questionnaire on Cognitive Decline to evaluate functionality, comorbidity and cognitive status, respectively. The EuroQol-5D assessed quality of life. Data were collected at baseline, during ICU and ward stay and 3, 6 and 12 months after hospital discharge. Paired or unpaired T-tests compared differences between groups (continuous variables), whereas the chi-square and Fisher exact tests were used for comparing dichotomous variables. For variables significant (P ≤ 0.1) on univariate analysis, a forward multiple regression analysis was performed. Results Only 48.9% of patients (mean age: 73.4 ± 5.5 years) were alive 12 months after discharge showing a significant decrease in functional autonomy (Lawton and Barthel Indexes) and quality of life (EuroQol-5D) compared to baseline status (P < 0.001, all). Multivariate analysis showed a higher Barthel Index and EQ-5D vas at hospital discharge to be associated factors of full functional recovery (P < 0.01, both). Thus, in patients with a Barthel Index ≥ 60 or EQ-5D vas ≥40 at discharge the hazard ratio for full functional recovery was 4.04 (95

The design of the patient cohort is an essential and fundamental part of any clinical patient study. Knowledge of the Electronic Health Records, underlying Database Management System, and the relevant clinical workflows are central to an effective cohort design. However, with technical, semantic, and organizational interoperability limitations, the database queries associated with a patient cohort may need to be reconfigured in every participating site. i2b2 and SHRINE advance the notion of patient cohorts as first class objects to be shared, aggregated, and recruited for research purposes across clinical sites. This paper reports on initial efforts to assess the integration of Medical Information Mart for Intensive Care (MIMIC) and Philips eICU, two large-scale anonymized intensive care unit (ICU) databases, using standard terminologies, i.e. LOINC, ICD9-CM and SNOMED-CT. Focus of this work is lab and microbiology observations and key demographics for patients with a primary cardiovascular ICD9-CM diagnosis. Results and discussion reflecting on reference core terminology standards, offer insights on efforts to combine detailed intensive care data from multiple ICUs worldwide. PMID:27774488

Support for fast comprehension of ICU data: visualization using metaphor graphics.

The time-oriented analysis of electronic patient records on (neonatal) intensive care units is a tedious and time-consuming task. Graphic data visualization should make it easier for physicians to assess the overall situation of a patient and to recognize essential changes over time. Metaphor graphics are used to sketch the most relevant parameters for characterizing a patient's situation. By repetition of the graphic object in 24 frames the situation of the ICU patient is presented in one display, usually summarizing the last 24 h. VIE-VISU is a data visualization system which uses multiples to present the change in the patient's status over time in graphic form. Each multiple is a highly structured metaphor graphic object. Each object visualizes important ICU parameters from circulation, ventilation, and fluid balance. The design using multiples promotes a focus on stability and change. A stable patient is recognizable at first sight, continuous improvement or worsening condition are easy to analyze, drastic changes in the patient's situation get the viewers attention immediately.

Traumatic brain injury is one of the major causes of death and disability among young people. Methylphenidate, a neural stimulant and protective drug, which has been mainly used for childhood attention deficit/hyperactivity disorder, has shown some benefits in late psychosocial problems in patients with traumatic brain injury. Its effect on arousal and consciousness has been also revealed in the sub-acute phase of traumatic brain injury. We studied its effect on the acute phase of moderate and severe traumatic brain injury (TBI) in relation to the length of ICU and hospital admission. Severely and moderately TBI patients (according to inclusion and exclusion criteria) were randomized to treatment and control groups. The treatment group received methylphenidate 0.3mg/kg per dose PO BID by the second day of admission until the time of discharge, and the control group received a placebo. Admission information and daily Glasgow Coma Scale (GCS) were recorded. Medical, surgical, and discharge plans for patients were determined by the attending physician, blinded to the study. Forty patients with severe TBI (GCS = 5-8) and 40 moderately TBI patients (GCS = 9-12) were randomly divided into treatment and control groups on the day of admission. In the severely TBI patients, both hospital and ICU length of stay, on average, were shorter in the treatment group compared with the control group. In the moderately TBI patients while ICU stay was shorter in the treatment group, there was no significant reduction of the period of hospitalization. There were no significant differences between the treatment and control groups in terms of age, sex, post resuscitation GCS, or brain CT scan findings, in either severely or moderately TBI patients. Methylphenidate was associated with reductions in ICU and hospital length of stay by 23% in severely TBI patients (P = 0.06 for ICU and P = 0.029 for hospital stay time). However, in the moderately TBI patients who received methylphenidate

Ventilator-associated pneumonia is an important cause of morbidity and mortality in critically ill patients. Evidence-based clinical practice guidelines for the prevention, diagnosis, and treatment of ventilator-associated pneumonia may improve outcomes, but optimal methods to ensure implementation of guidelines in the intensive care unit are unclear. Hence, we determined the effect of educational sessions augmented with reminders, and led by local opinion leaders, as strategies to implement evidence-based ventilator-associated pneumonia guidelines on guideline concordance and ventilator-associated pneumonia rates. Two-year prospective, multicenter, time-series study conducted between June 2007 and December 2009. Eleven ICUs (ten in Canada, one in the United States); five academic and six community ICUs. At each site, 30 adult patients mechanically ventilated >48 hrs were enrolled during four data collection periods (baseline, 6, 15, and 24 months). Guideline recommendations for the prevention, diagnosis, and treatment of ventilator-associated pneumonia were implemented using a multifaceted intervention (education, reminders, local opinion leaders, and implementation teams) directed toward the entire multidisciplinary ICU team. Clinician exposure to the intervention was assessed at 6, 15, and 24 months after the introduction of this intervention. The main outcome measure was aggregate concordance with the 14 ventilator-associated pneumonia guideline recommendations. One thousand three hundred twenty patients were enrolled (330 in each study period). Clinician exposure to the multifaceted intervention was high and increased during the study: 86.7%, 93.3%, 95.8%, (p < .001), as did aggregate concordance (mean [SD]): 50.7% (6.1), 54.4% (7.1), 56.2% (5.9), 58.7% (6.7) (p = .007). Over the study period, ventilator-associated pneumonia rates decreased (events/330 patients): 47 (14.2%), 34 (10.3%), 38 (11.5%), 29 (8.8%) (p = .03). A 2-yr multifaceted intervention to

The aim of this review is to focus the epidemiology and preventing measures of nosocomial infections that affect the critically ill patients. Most of them (over 80%) are related to the device utilization needed for patient life support but responsible for such complications as ventilator-associated pneumonia (VAP), catheter-related bloodstream infections (CRBSI), surgical site infections (SSI) and urinary tract infections (UTI). General recommendations include staff education and use of a surveillance program with a restrictive antibiotic policy. Adequate time must be allowed for hand washing and barrier precautions must always be used during device manipulation. The routine changing of central catheters is not necessary and increases costs; it is necessary to decrease the handling of administration sets, to use a more careful insertion technique and less frequent set replacement. Specific measures for VAP prevention are: 1). use of multi-use, closed-system suction catheters; 2). no routine change of the breathing circuit; 3). lubrication of the the endotracheal tube cuff with a water-soluble gel; 4). maintenance of patient in semi-recumbent position to improve chest physiotherapy. Specific measures for UTI prevention include: 1). use of a catheter-valve instead of a standard drainage system; 2). use of a silver-alloy, hydro gel-coated latex urinary catheter instead of uncoated catheters. By implementing effective preventive measures and maintaining strict surveillance of ICU infections, we hope to affect the associated morbidity, mortality, and cost that our patients and society bare. More clinical trials are needed to verify the efficacy of prevention measures of ICU infections.

BACKGROUND Intensive care units (ICUs) function frequently at capacity, requiring incoming critically ill patients to be placed in alternate geographically distinct ICUs. In some medical ICU populations, “boarding” in an overflow ICU has been associated with increased mortality. We hypothesized that surgical ICU patients experience more complications when boarding in an overflow ICU and that the frequency of these complications are greatest in boarders farthest from the home unit (HU). METHODS A 5-year (June 2005 to June 2010) retrospective review of a prospectively maintained ICU database was performed, and demographics, severity of illness, length of stay, and incidence of ICU complications were extracted. Distances between boarding patients’ rooms and the HU were measured. Complications occurring in patients located in the same floor (BUSF) and different floor (BUDF) boarding units were compared and stratified by distance from HU to the patient room. Logistic regression was used to develop control for known confounders. RESULTS A total of 7,793 patients were admitted to the HU and 833 to a boarding unit (BUSF, n = 712; BUDF, n = 121). Boarders were younger, had a lower length of stay, and Acute Physiology and Chronic Health Evaluation II and were more of tentrauma/emergency surgery patients. Compared with in-HU patients, the incidence of aspiration pneumonia (2.2% vs. 3.6%, p < 0.01) was greater in BUSF patients and highest in those farthest from the HU (odds ratio [OR],2.39;p =0.01). Delirium occurred less often in HU than in BUDF patients (3.3% vs. 8.3 %, p < 0.01), and both delirium (OR, 6.09, p < 0.01) and ventilator-associated pneumonia (OR, 4.49, p < 0.05) were more frequent in patients farther from the HU. CONCLUSION Certain ICU complications occur more frequently in boarding patients particularly if they are located on a different floor or far from the HU. When surgical ICU bed availability forces overflow admissions to non–home ICUs, greater

Surgical intensive care units (SICUs) are special units for critically ill surgical patients both in the pre and postoperative period. There is little aggregated information about surgical patients who are admitted to the Thai surgical ICU. The objective of this report was to describe patient characteristics, outcomes of ICU care, incidence and outcomes of adverse events in the SICU in the participating SICUs. This multi-center, prospective, observational study of nine university-based SICUs was done. All admitted patients with ages >18 years old were included. Information about patient characteristics, underlying medical problems, indication and type of ICU admission, severity score as ASA physical status in operative patients, APACHE II score and SOFA score, adverse events of interest, ventilator days, ICU and 28 days mortality. The association of outcome and predictors was reported by relative risk (RR) with 95% confidence interval (95% CI). Statistical significant difference was defined by p<0.05. During April 2011-January 2013 of total cohort time, a total of 4,652 patients from nine university-based SICUs were included in this study. Mode of patient age was 71-75 year old for both sexes. Median (IQR) of APACHE II scores and SOFA scores were 10 (7-10) and 2 (1-5), respectively. Seventy eight percent of patients were postoperative patients and 50% of them were ASA physical status III. The median of ICU stay was 2 (IQR 1-4) days. Each day of ICU increment was associated with increased 1.4 days of a hospital stay. Three percent of survived at discharge were clinically inappropriate discharge resulting in ICU readmission. Sixty-five percent were discharged home after ICU admission. ICU and 28 days mortality was 9.6% and 13.8%. The seven most common adverse events were sepsis (19.5%), acute kidney injury (AKI) (16.9%), new cardiac arrhythmias (6.2%), acute respiratory distress syndrome (ARDS) (5.8%), cardiac arrest (4.9%), delirium (3.5%) and reintubation within 72

Wireless technology in the ICU: boon or ban?

Gladman, Aviv S; Lapinsky, Stephen E

2007-01-01

Wireless communication and data transmission are playing an increasing role in the critical care environment. Early anecdotal reports of electromagnetic interference (EMI) with intensive care unit (ICU) equipment resulted in many institutions banning these devices. An increasing literature database has more clearly defined the risks of EMI. Restrictions to the use of mobile devices are being lifted, and it has been suggested that the benefits of improved communication may outweigh the small risks. However, increased use of cellular phones and ever changing communication technologies require ongoing vigilance by healthcare device manufacturers, hospitals and device users, to prevent potentially hazardous events due to EMI.

Epidemiological cohort multicenter prospective study, evaluating patients admitted for a period of 31days (June 01 to July 01, 2015) until hospital discharge. Epidemiological and clinical data were collected daily until ICU discharge, as was the incidence of PU, either new or present on admission. 10 general adult ICUs. We evaluated 332 patients, 52.1% male, mean age 63.1 years. The most common cause of admission was medical diseases (50.3%), and the mean APACHE II score was 14.9. A total of 45 patients (13.6%) had PU; the most common sites were sacral, calcaneal, ears, and trochanter. The incidence of PU was related to predictive factors, such as the Braden Scale and length of lack of nutrition. The presence of PU was strongly related to unfavorable outcomes, such as Mechanical Ventilation (MV) duration and ICU and hospital mortality. PU incidence is related to severity of the patient's condition and predicted by Braden Scale score. The presence of PU is also related to adverse outcomes, such as MV duration and ICU and hospital mortality. It was also shown that patients with PU have a higher incidence of medical complications, such as acute renal failure, pneumonia, and the need for vasoactive drugs. Copyright © 2017 Elsevier Ltd.

In general, sleeping and activity patterns vary between individuals. This attribute, known as chronotype, may affect night shift performance. In the intensive care unit (ICR), night shift performance may impact patient safety. We have investigated the effect of chronotype and social demographics on sleepiness, fatigue, and night shift on the performance of nurses. This was a prospective observational cohort study which assessed the performance of 96 ICU night shift nurses during the day and night shifts in a mixed medical-surgical ICU in the Netherlands. We determined chronotype and assessed sleeping behaviour for each nurse prior to starting shift work and before free days. The level of sleepiness and fatigue of nurses during the day and night shifts was determined, as was the effect of these conditions on psychomotor vigilance and mathematical problem-solving. The majority of ICU nurses had a preference for early activity (morning chronotype). Compared to their counterparts (i.e. evening chronotypes), they were more likely to nap before commencing night shifts and more likely to have young children living at home. Despite increased sleepiness and fatigue during night shifts, no effect on psychomotor vigilance was observed during night shifts. Problem-solving accuracy remained high during night shifts, at the cost of productivity. Most of the ICU night shift nurses assessed here appeared to have adapted well to night shift work, despite the high percentage of morning chronotypes, possibly due to their 8-h shift duration. Parental responsibilities may, however, influence shift work tolerance.

Failure to rapidly identify high-value information due to inappropriate output may alter user acceptance and satisfaction. The information needs for different intensive care unit (ICU) providers are not the same. This can obstruct successful implementation of electronic medical record (EMR) systems. We evaluated the implementation experience and satisfaction of providers using a novel EMR interface-based on the information needs of ICU providers-in the context of an existing EMR system. This before-after study was performed in the ICU setting at two tertiary care hospitals from October 2013 through November 2014. Surveys were delivered to ICU providers before and after implementation of the novel EMR interface. Overall satisfaction and acceptance was reported for both interfaces. A total of 246 before (existing EMR) and 115 after (existing EMR+novel EMR interface) surveys were analyzed. 14% of respondents were prescribers and 86% were non-prescribers. Non-prescribers were more satisfied with the existing EMR, whereas prescribers were more satisfied with the novel EMR interface. Both groups reported easier data gathering, routine tasks & rounding, and fostering of team work with the novel EMR interface. This interface was the primary tool for 18% of respondents after implementation and 73% of respondents intended to use it further. Non-prescribers reported an intention to use this novel interface as their primary tool for information gathering. Compliance and acceptance of new system is not related to previous duration of work in ICU, but ameliorates with the length of EMR interface usage. Task-specific and role-specific considerations are necessary for design and successful implementation of a EMR interface. The difference in user workflows causes disparity of the way of EMR data usage. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Electric versus manual tooth brushing among neuroscience ICU patients: is it safe?

PubMed

Prendergast, Virginia; Hagell, Peter; Hallberg, Ingalill Rahm

2011-04-01

Poor oral hygiene has been associated with ventilator-acquired pneumonia. Yet providing oral care for intubated patients is problematic. Furthermore, concerns that oral care could raise intracranial pressure (ICP) may cause nurses to use foam swabs to provide oral hygiene rather than tooth brushing as recommended by the American Association of Critical-Care Nurses. Evidence is needed to support the safety of toothbrushing during oral care. We therefore evaluated ICP and cerebral perfusion pressure (CPP) during oral care with a manual or electric toothbrush in intubated patients in a neuroscience intensive care unit (ICU). As part of a larger 2-year, prospective, randomized clinical trial, 47 adult neuroscience ICU patients with an ICP monitor received oral care with a manual or electric toothbrush. ICP and CPP were recorded before, during, and after oral care over the first 72 h of admission. Groups did not differ significantly in age, gender, or severity of injury. Of 807 ICP and CPP measurements obtained before, during, and after oral care, there were no significant differences in ICP (P = 0.72) or CPP (P = 0.68) between toothbrush methods. Analysis of pooled data from both groups revealed a significant difference across the three time points (Wilks' lambda, 12.56; P < 0.001; partial η(2), 0.36). ICP increased significantly (mean difference, 1.7 mm Hg) from before to during oral care (P = 0.001) and decreased significantly (mean difference, 2.1 mm Hg) from during to after oral care (P < 0.001). In the absence of preexisting intracranial hypertension during oral care, tooth brushing, regardless of method, was safely performed in intubated neuroscience ICU patients.

Hepatic encephalopathy (HE) influences short-term and long-term prognoses. Recently, glycerol phenylbutyrate (PB), that lowers ammonia by providing an alternate pathway to urea for waste nitrogen excretion, has shown that it was effective in preventing the occurrence of HE in RCT. The aim was to assess the benefits of sodium PB in cirrhotic patients admitted to ICU for overt HE, in terms of ammonia levels decrease, neurological improvement, and survival. Cirrhotic patients who presented with overt HE, ammonia levels >100 μmol/L, and did not display any contra-indication were included. Sodium PB was administered at 200 mg/kg/day. Control group included historical controls treated by standard therapy, matched for age, sex, MELD score, and severity of HE. Eighteen patients were included and treated with sodium PB (age: 59 [45-68], male gender: 15 [83%], Child-Pugh B: 8 [44%], Child-Pugh C: 10 [56%], and MELD score: 16 [13-23]). Ammonia levels significantly decreased in the PB as compared to the control group from inclusion to 12 h and from inclusion to 48 h (P = 0.0201 and P = 0.0230, respectively). The proportion of patients displaying neurological improvement was only higher in the PB-treated group as compared to controls at ICU discharge (15 [83%] vs. 9 [50%], P = 0.0339). ICU discharge survival was significantly higher in patients treated with PB (17 [94%] vs. 9 [50%], P = 0.0017). In cirrhotic patients with overt HE, sodium PB could be effective in reducing ammonia levels and might be effective in improving neurological status and ICU discharge survival. More extensive data, especially a RCT, are mandatory. © 2017 Société Française de Pharmacologie et de Thérapeutique.

Electronic Health Record (EHR)-based sepsis alert systems have failed to demonstrate improvements in clinically meaningful endpoints. However, the effect of implementation barriers on the success of new sepsis alert systems is rarely explored. To test the hypothesis time to severe sepsis alert acknowledgement by critical care clinicians in the ICU setting would be reduced using an EHR-based alert acknowledgement system compared to a text paging-based system. In one arm of this simulation study, real alerts for patients in the medical ICU were delivered to critical care clinicians through the EHR. In the other arm, simulated alerts were delivered through text paging. The primary outcome was time to alert acknowledgement. The secondary outcomes were a structured, mixed quantitative/qualitative survey and informal group interview. The alert acknowledgement rate from the severe sepsis alert system was 3% ( N  = 148) and 51% ( N  = 156) from simulated severe sepsis alerts through traditional text paging. Time to alert acknowledgement from the severe sepsis alert system was median 274 min ( N  = 5) and median 2 min ( N  = 80) from text paging. The response rate from the EHR-based alert system was insufficient to compare primary measures. However, secondary measures revealed important barriers. Alert fatigue, interruption, human error, and information overload are barriers to alert and simulation studies in the ICU setting.

The aim of this case-control study is to explore clinical objective variables for diagnosing delirium of intensive care unit (ICU) patients. According to the method of prospective case-control study, critical adult postoperative patients who were transferred to ICU of Peking University People's Hospital from October 2015 to May 2016 and needed mechanical ventilation were included. After evaluating the Richmond agitation sedation scale score (RASS), the patients whose score were -2 or greater were sorted into two groups, delirium and non-delirium, according to the confusion assessment method for the ICU (CAM-ICU). Then these patients were observed by domestic multifunctional detector for electroencephalographic (EEG) variables such as brain lateralization, brain introvert, brain activity, brain energy consumption, focus inward, focus outward, cerebral inhibition, fatigue, sleep severity, sedation index, pain index, anxiety index, fidgety index, stress index and the cerebral blood flow (CBF) index which was named of perfusion index. Other variables including indexes of ICU blood gas analysis, which was consisted of variables of blood gas analysis, routine blood test and biochemistry, previous history and prognostic outcome was recorded. Binary logistic regression was used for multivariate analysis. Forty-three postoperative patients, who needed intensive care, were included. Eighteen were in delirium group and twenty-five in control group. Excluding the trauma, variables like gender, age, temperature, heart rate, respiratory rate, mean arterial pressure, acute physiology and chronic health evaluationII(APACHEII) score, organ failure, dementia and emergency surgery didn't show any statistical significance between two groups. The trauma in delirious patients increased obviously compared with the control group (33.3% vs. 4.0%, P = 0.031). Except for the brain activity [122.47 (88.62, 154.21) vs. 89.40 (86.27, 115.97), P = 0.034], there were no statistical differences in

Atmospheric pollution was monitored at different sites: before sevoflurane delivery (baseline) and during sedation with the probe 15 cm up to the MIRUS system (S1) and 15 cm from the filter-Reflector group (S2). Sixty-two patients were enrolled in the study. No technical failure occurred. Median Richmond Agitation Sedation Scale was -4.5 (interquartile range, -5 to -3.6) with sevoflurane delivered at a median minimum alveolar concentration of 0.45% (interquartile range, 0.4-0.53) yielding a mean inspiratory and expiratory concentrations of 0.79% (SD, 0.24) and 0.76% (SD, 0.18), respectively. Median awakening time was 4 minutes (2.2-5 min). Median duration of sevoflurane administration was 3.33 hours (2.33-5.75 hr), range 1-19 hours with a mean consumption of 7.89 mL/hr (SD, 2.99). Hemodynamics remained stable over the study period, and no laboratory data indicated liver or kidney injury or dysfunction. Median sevoflurane room air concentration was 0.10 parts per million (interquartile range, 0.07-0.15), 0.17 parts per million (interquartile range, 0

To evaluate effects of a PRECEDE-PROCEED Model based, nurse-delivered Ergonomic Risk Management Program (ERMP) in the aim of reducing musculoskeletal symptoms of intensive care unit (ICU) nurses. This pre-test post-test design for non-equivalent control groups study comprised 72 ICU nurses from two hospitals. A randomised sampling was done through the study population. The ERMP was delivered as an intervention including 26weeks of follow-up. Data was collected by "Descriptives of Nurses and Ergonomic Risk Reporting Form", "Rapid Upper Risk Assessment Form (RULA)", "ICU Environment Assessment Form" and "Personal interviews form". There was no difference between sociodemographic characteristics, work and general health conditions within intervention and control group. One month after the intervention, nurses had significant decrease in their total RULA scores during bending down and patient repositioning movements as 1.40 and 0.82, respectively. Six months after the ERMP, the mean total RULA scores of nurses during the patient repositioning was 4.39±1.49 which meant "immediate further analyses and modifications recommended". After all, pain intensity scores, medication use due to pain, and RULA ergonomic risk scores were significantly decreased, while exercise frequency was increased. The ERMP was effective to increase exercise frequency and to decrease musculoskeletal pain and ergonomic risk levels of ICU nurses. Copyright © 2018 Elsevier Ltd. All rights reserved.

OBJECTIVE Conflict is common between physicians and surrogate decision makers around end-of-life care in intensive care units (ICU). Involving experts in conflict management improve outcomes, but little is known about what differences in conflict management styles may explain the benefit. We used simulation to examine potential differences in how palliative care specialists manage conflict with surrogates about end-of-life treatment decisions in ICUs compared with intensivists. DESIGN Subjects participated in a high-fidelity simulation of conflict with a surrogate in an ICU. In this simulation, a medical actor portrayed a surrogate decision maker during an ICU family meeting who refuses to follow an advance directive that clearly declines advanced life-sustaining therapies. We audio-recorded the simulation encounters and applied a coding framework to quantify conflict management behaviors, which was organized into two categories: task-focused communication and relationship-building. We used negative binomial modeling to determine whether there were differences between palliative care specialists’ and intensivists’ use of task-focused communication and relationship building. SETTING Single academic medical center ICU PARTICIPANTS Palliative care specialists and intensivists INTERVENTIONS none MEASUREMENTS and MAIN RESULTS We enrolled 11 palliative care specialists and 25 intensivists. The palliative care specialists were all attending physicians. The intensivist group consisted of 11 attending physicians, 9 pulmonary and critical care fellows, and 5 internal medicine residents rotating in the intensive care unit. We excluded the 5 residents from the primary analysis in order to reduce confounding due to training level. Physicians’ mean age was 37 years with a mean of 8 years in practice. Palliative care specialists used 55% fewer task-focused communication statements (Incidence Rate Ratio 0.55, 95% CI 0.36–0.83, p= 0.005) and 48% more relationship building

Flexible intensive care unit (ICU) visiting hours have been proposed as a means to improve patient-centred and family-centred care. However, randomised trials evaluating the effects of flexible family visitation models (FFVMs) are scarce. This study aims to compare the effectiveness and safety of an FFVM versus a restrictive family visitation model (RFVM) on delirium prevention among ICU patients, as well as to analyse its potential effects on family members and ICU professionals. A cluster-randomised crossover trial involving adult ICU patients, family members and ICU professionals will be conducted. Forty medical-surgical Brazilian ICUs with RFVMs (<4.5 hours/day) will be randomly assigned to either an RFVM (visits according to local policies) or an FFVM (visitation during 12 consecutive hours per day) group at a 1:1 ratio. After enrolment and follow-up of 25 patients, each ICU will be switched over to the other visitation model, until 25 more patients per site are enrolled and followed. The primary outcome will be the cumulative incidence of delirium among ICU patients, measured twice a day using the Confusion Assessment Method for the ICU. Secondary outcome measures will include daily hazard of delirium, ventilator-free days, any ICU-acquired infections, ICU length of stay and hospital mortality among the patients; symptoms of anxiety and depression and satisfaction among the family members; and prevalence of burnout symptoms among the ICU professionals. Tertiary outcomes will include need for antipsychotic agents and/or mechanical restraints, coma-free days, unplanned loss of invasive devices and ICU-acquired pneumonia, urinary tract infection or bloodstream infection among the patients; self-perception of involvement in patient care among the family members; and satisfaction among the ICU professionals. The study protocol has been approved by the research ethics committee of all participant institutions. We aim to disseminate the findings through

To evaluate the relationship between rates of discharge directly to home (DDH) from the intensive care unit (ICU) and bed availability (ward and ICU). Also to identify patient characteristics that make them candidates for safe DDH and describe transfer delay impact on length of stay (LOS). Retrospective cohort study of all adult patients who survived their stay in our medical-surgical-trauma ICU between April 2003 and March 2015. Median age was 49 years (interquartile range [IQR]: 33.5-60.4), and the majority of the patients were males (54.8%). Median number of preexisting comorbidities was 5 (IQR: 2-7) diagnoses. Discharge directly to home increased from 28 (3.1% of all survivors) patients in 2003 to 120 (12.5%) patients in 2014. The mean annual rate of DDH was between 11% and 12% over the last 6 years. Approximately 62% (n = 397) of patients waited longer than 4 hours for a ward bed, with a median delay of 2.0 days (IQR: 0.5-4.7) before being DDH. There was an inverse correlation between ICU occupancy and DDH rates ( r P = -.55, P < .0001, 95% confidence interval [CI] = -0.36 to -0.69, R 2 = .29). There was no correlation with ward occupancy and DDH rates ( r s = -.055, P = .64, 95% CI = -0.25 to 0.21). The DDH rates have been increasing over time at our institution and were inversely correlated with ICU bed occupancy but were not associated with ward occupancy. The DDH patients are young, have few comorbidities on admission, and few discharge diagnoses, which are usually reversible single system problems with low disease burden. Transfers to the ward are delayed in a majority of cases, leading to increased ICU LOS and likely increased overall hospital LOS as well.

To describe the clinical characteristics, laboratory data, and clinical outcomes of patients with and without sepsis admitted to the ICU of a private hospital in the city of Salvador, Brazil, and to identify clinical variables related to a worse prognosis in those with sepsis. This was a longitudinal study including all patients admitted to the general ICU of the Hospital Português, in the city of Salvador, Brazil, between June of 2008 and March of 2009. At ICU admission, two groups of patients were identified: with sepsis and without sepsis. Epidemiological, clinical and laboratory data were collected, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score was calculated. Of the 144 patients in the study, 29 (20.1%) had sepsis. Among the patients with sepsis, males accounted for 55.2%, the mean age was 73.1 ± 14.6 years, and the mean APACHE II score was 23.8 ± 9.1, compared with 36.3%, 68.7 ± 17.7 years, and 18.4 ± 9.5, respectively, among those without sepsis. There were significant associations between a diagnosis of sepsis and the following variables: APACHE II score; in-hospital mortality; ICU mortality; HR; mean arterial pressure; hematocrit level; white blood cell count; and antibiotic use. The use of life support measures and lower hematocrit levels were associated with a worse prognosis in the patients with sepsis. The patients diagnosed with sepsis presented worse clinical outcomes, probably due to their greater severity. Hematocrit level was the only variable that was a predictor of mortality risk in the patients with sepsis.

Embedding measurement within existing computerized data systems: scaling clinical laboratory and medical records heart failure data to predict ICU admission.

PubMed

Fisher, William P; Burton, Elizabeth C

2010-01-01

This study employs existing data sources to develop a new measure of intensive care unit (ICU) admission risk for heart failure patients. Outcome measures were constructed from laboratory, accounting, and medical record data for 973 adult inpatients with primary or secondary heart failure. Several scoring interpretations of the laboratory indicators were evaluated relative to their measurement and predictive properties. Cases were restricted to tests within first lab draw that included at least 15 indicators. After optimizing the original clinical observations, a satisfactory heart failure severity scale was calibrated on a 0-1000 continuum. Patients with unadjusted CHF severity measures of 550 or less were 2.7 times more likely to be admitted to the ICU than those with higher measures. Patients with low HF severity measures (550 or less) adjusted for demographic and diagnostic risk factors are about six times more likely to be admitted to the ICU than those with higher adjusted measures. A nomogram facilitates routine clinical application. Existing computerized data systems could be programmed to automatically structure clinical laboratory reports using the results of studies like this one to reduce data volume with no loss of information, make laboratory results more meaningful to clinical end users, improve the quality of care, reduce errors and unneeded tests, prevent unnecessary ICU admissions, lower costs, and improve patient satisfaction. Existing data typically examined piecemeal form a coherent scale measuring heart failure severity sensitive to increased likelihood of ICU admission. Marked improvements in ROC curves were found for the aggregate measures relative to individual clinical indicators.

Bacterial parotitis is a common childhood disease with a favorable outcome. Staphylococcus aureus is the most frequently involved pathogen. Clinical presentation in adult patients can be misleading, Onset occurs in patients with multiple comorbidities, making diagnosis difficult--particularly in ICU. Different pathogens are found in adults with worse outcomes observed. We report here the case of a critically ill patient and discuss diagnosis and management of bacterial parotitis.

To report the clinical and laboratory characteristics, clinical courses, and outcomes of Mayo Clinic, Rochester, MN, ICU-managed autoimmune encephalitis patients (January 1st 2003-December 31st 2012). Based on medical record review, twenty-five patients were assigned to Group 1 (had ≥1 of classic autoimmune encephalitis-specific IgGs, n = 13) or Group 2 (had ≥3 other characteristics supporting autoimmunity, n = 12). Median admission age was 47 years (range 22-88); 17 were women. Initial symptoms included ≥1 of subacute confusion or cognitive decline, 13; seizures, 12; craniocervical pain, 5; and personality change, 4. Thirteen Group 1 patients were seropositive for ≥1 of VGKC-complex-IgG (6; including Lgi1-IgG in 2), NMDA-R-IgG (4), AMPA-R-IgG (1), ANNA-1 (1), Ma1/Ma2 antibody (1), and PCA-1 (1). Twelve Group 2 patients had ≥3 other findings supportive of an autoimmune diagnosis (median 4; range 3-5): ≥1 other antibody type detected, 9; an inflammatory CSF, 8; ≥1 coexisting autoimmune disease, 7; an immunotherapy response, 7; limbic encephalitic MRI changes, 5; a paraneoplastic cause, 4; and diagnostic neuropathological findings, 2. Among 11 patients ICU-managed for ≥4 days, neurological improvements were attributable to corticosteroids (5/7 treated), plasmapheresis (3/7), or rituximab (1/3). At last follow-up, 10 patients had died. Of the remaining 15 patients, 6 (24%) had mild or no disability, 3 (12%) had moderate cognitive problems, and 6 (24%) had dementia (1 was bed bound). Median modified Rankin score at last follow-up was 3 (range 0-6). Good outcomes may occur in ICU-managed autoimmune encephalitis patients. Clinical and testing characteristics are diverse. Comprehensive diagnostics should be pursued to facilitate timely treatment.

Wireless technology in the ICU: boon or ban?

PubMed Central

Gladman, Aviv S; Lapinsky, Stephen E

2007-01-01

Wireless communication and data transmission are playing an increasing role in the critical care environment. Early anecdotal reports of electromagnetic interference (EMI) with intensive care unit (ICU) equipment resulted in many institutions banning these devices. An increasing literature database has more clearly defined the risks of EMI. Restrictions to the use of mobile devices are being lifted, and it has been suggested that the benefits of improved communication may outweigh the small risks. However, increased use of cellular phones and ever changing communication technologies require ongoing vigilance by healthcare device manufacturers, hospitals and device users, to prevent potentially hazardous events due to EMI.

Critically ill patients in the intensive care unit (ICU) are at risk of clinically important gastrointestinal bleeding, and acid suppressants are frequently used prophylactically. However, stress ulcer prophylaxis may increase the risk of serious adverse events and, additionally, the quantity and quality of evidence supporting the use of stress ulcer prophylaxis is low. The aim of the SUP-ICU trial is to assess the benefits and harms of stress ulcer prophylaxis with a proton pump inhibitor in adult patients in the ICU. We hypothesise that stress ulcer prophylaxis reduces the rate of gastrointestinal bleeding, but increases rates of nosocomial infections and myocardial ischaemia. The overall effect on mortality is unpredictable. The SUP-ICU trial is an investigator-initiated, pragmatic, international, multicentre, randomised, blinded, parallel-group trial of stress ulcer prophylaxis with a proton pump inhibitor versus placebo (saline) in 3350 acutely ill ICU patients at risk of gastrointestinal bleeding. The primary outcome measure is 90-day mortality. Secondary outcomes include the proportion of patients with clinically important gastrointestinal bleeding, pneumonia, Clostridium difficile infection or myocardial ischaemia, days alive without life support in the 90-day period, serious adverse reactions, 1-year mortality, and health economic analyses. The sample size will enable us to detect a 20 % relative risk difference (5 % absolute risk difference) in 90-day mortality assuming a 25 % event rate with a risk of type I error of 5 % and power of 90 %. The trial will be externally monitored according to Good Clinical Practice standards. Interim analyses will be performed after 1650 and 2500 patients. The SUP-ICU trial will provide high-quality data on the benefits and harms of stress ulcer prophylaxis with a proton pump inhibitor in critically ill adult patients admitted in the ICU.

Only limited pharmacokinetic data are available for anidulafungin in ICU patients, especially in patients treated for severe intra-abdominal infection (IAI). This was a prospective multicentre observational study in ICU patients with suspected yeast IAI. All patients received an intravenous loading dose of 200 mg of anidulafungin, followed by 100 mg/day. Thirteen blood samples were drawn between day 1 and day 5 for pharmacokinetic analysis. Samples were analysed by an HPLC-tandem MS method. Demographics and SAPS2 and SOFA scores were recorded. Fourteen patients with a median age (IQR) of 62 years (48-70) and with a mean BMI of 30.5 kg/m 2 were included from three centres; 57.1% were women. Their median (IQR) SAPS2 score was 54 (45-67) and their median (IQR) SOFA score was 8 (7-12). Six patients with community-acquired IAI and eight patients with nosocomial-acquired IAI were included. Twelve yeasts were isolated: six Candida albicans , two Candida glabrata , two Candida tropicalis , one Candida parapsilosis and one Candida krusei . Pharmacokinetic parameters were as follows [mean (% coefficient of variation)]: C max (mg/L) = 6.0 (29%); T max (h) = 1.6 (25.8%); C min (mg/L) = 3.2 (36.8%); AUC 0-24 (mg·h/L) = 88.9 (38.6%); t 1/2 (h) = 42.1 (68.2%); CL (L/h) = 1.2 (42.3%); and V (L) = 72.8 (87.8%). A two-compartment model best described the anidulafungin concentrations in the population pharmacokinetic study. The pharmacokinetic parameters of anidulafungin in critically ill ICU patients with complicated IAI are similar to those observed in the literature. However, an increased V and a longer t 1/2 were observed in this study. (EudraCT No. 2010-018695-25). © The Author 2017.

2010-03-05

The demand for inpatient medical services increases during influenza season. A scoring system capable of identifying influenza patients at low risk death or ICU admission could help clinicians make hospital admission decisions. Hospitalized patients with laboratory confirmed influenza were identified over 3 influenza seasons at 25 Ontario hospitals. Each patient was assigned a score for 6 pneumonia severity and 2 sepsis scores using the first data available following their registration in the emergency room. In-hospital mortality and ICU admission were the outcomes. Score performance was assessed using the area under the receiver operating characteristic curve (AUC) and the sensitivity and specificity for identifying low risk patients (risk of outcome <5%). The cohort consisted of 607 adult patients. Mean age was 76 years, 12% of patients died (71/607) and 9% required ICU care (55/607). None of the scores examined demonstrated good discriminatory ability (AUC>or=0.80). The Pneumonia Severity Index (AUC 0.78, 95% CI 0.72-0.83) and the Mortality in Emergency Department Sepsis score (AUC 0.77, 95% 0.71-0.83) demonstrated fair predictive ability (AUC>or=0.70) for in-hospital mortality. The best predictor of ICU admission was SMART-COP (AUC 0.73, 95% CI 0.67-0.79). All other scores were poor predictors (AUC <0.70) of either outcome. If patients classified as low risk for in-hospital mortality using the PSI were discharged, 35% of admissions would have been avoided. None of the scores studied were good predictors of in-hospital mortality or ICU admission. The PSI and MEDS score were fair predictors of death and if these results are validated, their use could reduce influenza admission rates significantly.

Objective To compare the efficacy and safety of scheduled low-dose, haloperidol vs. placebo for the prevention of delirium [Intensive Care Delirium Screening Checklist (ICDSC) ≥ 4)] administered to critically ill adults with subsyndromal delirium (ICDSC = 1-3). Design Randomized, double-blind, placebo-controlled trial. Setting Three 10-bed ICUs (2 medical; 1 surgical) at an academic medical center in the U.S. Patients Sixty-eight mechanically ventilated patients with subsyndromal delirium without complicating neurologic conditions, cardiac surgery or requiring deep sedation. Interventions Patients were randomly assigned to receive intravenous haloperidol 1 mg or placebo every six hours until either delirium (ICDSC ≥ 4 with psychiatric confirmation), therapy ≥ 10 days or ICU discharge occurred. Measurements and Main Results Baseline characteristics were similar between the haloperidol (n=34) and placebo (n=34) groups. A similar number of patients given haloperidol [12/34 (35%)] and placebo [8/34 (23%)] patients developed delirium (p=0.29). Haloperidol use reduced the hours per study day spent agitated (SAS ≥ 5) (p=0.008), but did not influence the proportion of 12-hour ICU shifts patients’ spent alive without coma (SAS ≤ 2) or delirium (p=0.36), the time to first delirium occurrence (p=0.22) nor delirium duration (p=0.26). Days of mechanical ventilation (p=0.80), ICU mortality (p=0.55) and ICU patient disposition (p=0.22) were similar in the two groups. The proportion of patients who developed QTc-interval prolongation (p=0.16), extrapyramidal symptoms (p=0.31), excessive sedation (p=0.31) or new-onset hypotension (p=1.0) that resulted in study drug discontinuation was comparable between the two groups. Conclusions Low-dose scheduled haloperidol, initiated early in the ICU stay, does not prevent delirium and has little therapeutic advantage in mechanically ventilated, critically ill adults with subsyndromal delirium.

This paper presents an exploratory case study of clinician-patient communications in a specific clinical environment. It describes how intensive care unit (ICU) clinicians' technical and social categorizations of patients and families shape the flow of communication in these acute care settings. Drawing on evidence from a year-long ethnographic study of four ICUs, we develop a typology of patients and families as viewed by the clinicians who care for them. Each type, or category, of patient is associated with differing communication strategies, with compliant patients and families engaged in greater depth. In an era that prioritizes patient engagement through communication for all patients, our findings suggest that ICU teams need to develop new strategies for engaging and communicating with not just compliant patients and families, but those who are difficult as well. We discuss innovative methods for developing such strategies.

To explore family members' experiences of long-term intensive care unit (ICU) patients' pathways towards survival and to highlight family members' efforts to promote the patient's health during the ICU stay. Although considerable research has been devoted to the substantial burden of long-term ICU patients, less attention has been paid to health promoting factors that facilitate patients' health and survival during ICU stays. Support from family members can improve patient outcome. However, there is little knowledge of the specific contributions provided by family members. A hermeneutic phenomenological approach, within the context of Antonovsky's salutogenic theory and Merleau-Ponty's phenomenology of the body, involving the body as the fundament of experience and understanding. In-depth qualitative interviews. Thirteen family members of long-term ICU patients were interviewed once, at six to 18 months after ICU discharge. The consolidated criteria for reporting qualitative research were used. Three themes were identified: (1) A body at a breaking point; (2) Family members' presence and; (3) Breaking through. In the perspective of the family members, their beloved ones were at a breaking point between life and death. The family's presence was significantly health promoting, demonstrating and communicating love and sensitivity. Moreover, family members' understanding of the patient's unique characteristics and personality was crucial to the patient's experience of being understood, recognized and acknowledged. Inner strength represented a life force capable of moving the patient from the breaking point towards a breakthrough towards life. Family members purposely used their knowledge about the patient to trigger, nurture and release the patient's inner strength. Family presence helps to trigger, arouse and release a patient's inner strength, representing important health promoting factors facilitating patients' health and survival during an ICU stay.

We compared in a single mixed intensive care unit (ICU) patients with influenza A(H1N1) pdm09 between pandemic and postpandemic periods. Retrospective analysis of prospectively collected data in 2009-2016. Data are expressed as median (25th-75th percentile) or number (percentile). Seventy-six influenza A(H1N1) pdm09 patients were admitted to the ICU: 16 during the pandemic period and 60 during the postpandemic period. Postpandemic patients were significantly older (60 years vs. 43 years, p < 0.001) and less likely to have epilepsy or other neurological diseases compared with pandemic patients (5 [8.3%] vs. 6 [38%], respectively; p = 0.009). Postpandemic patients were more likely than pandemic patients to have cardiovascular disease (24 [40%] vs. 1 [6%], respectively; p = 0.015), and they had higher scores on APACHE II (17 [13-22] vs. 14 [10-17], p = 0.002) and SAPS II (40 [31-51] vs. 31 [25-35], p = 0.002) upon admission to the ICU. Postpandemic patients had higher maximal SOFA score (9 [5-12] vs. 5 [4-9], respectively; p = 0.03) during their ICU stay. Postpandemic patients had more often septic shock (40 [66.7%] vs. 8 [50.0%], p = 0.042), and longer median hospital stays (15.0 vs. 8.0 days, respectively; p = 0.006). During 2015-2016, only 18% of the ICU- treated patients had received seasonal influenza vaccination. Postpandemic ICU-treated A(H1N1) pdm09 influenza patients were older and developed more often septic shock and had longer hospital stays than influenza patients during the 2009 pandemic.

A web-based real-time operating, management, and monitoring system for checking temperature and humidity within infant incubators using the Intranet has been developed and installed in the infant Intensive Care Unit (ICU). We have created a pilot system which has a temperature and humidity sensor and a measuring module in each incubator, which is connected to a web-server board via an RS485 port. The system transmits signals using standard web-based TCP/IP so that users can access the system from any Internet-connected personal computer in the hospital. Using this method, the system gathers temperature and humidity data transmitted from the measuring modules via the RS485 port on the web-server board and creates a web document containing these data. The system manager can maintain centralized supervisory monitoring of the situations in all incubators while sitting within the infant ICU at a work space equipped with a personal computer. The system can be set to monitor unusual circumstances and to emit an alarm signal expressed as a sound or a light on a measuring module connected to the related incubator. If the system is configured with a large number of incubators connected to a centralized supervisory monitoring station, it will improve convenience and assure meaningful improvement in response to incidents that require intervention.

Methicillin-resistant Staphylococcus aureus infection is a significant contributor to morbidity and mortality in hospitalized patients worldwide. Numerous healthcare bodies in Europe and the United States have championed active surveillance per the "search and destroy" model. However, this strategy is associated with significant economic, logistical, and patient costs without any impact on other hospital-acquired pathogens. We evaluated whether horizontal infection control strategies could decrease the prevalence of methicillin-resistant S. aureus infection in the ICU, without the need for active surveillance. Retrospective, observational study in the surgical ICU of a tertiary care medical center in Boston, MA, from 2005 to 2012. A total of 6,697 patients in the surgical ICU. Evidence-based infection prevention strategies were implemented in an iterative fashion, including 1) hand hygiene program with refresher education campaign, 2) chlorhexidine oral hygiene program, 3) chlorhexidine bathing, 4) catheter-associated bloodstream infection program, and 5) daily goals sheets. The prevalence of methicillin-resistant S. aureus infection fell from 2.66 to 0.69 per 1,000 patient days from 2005 to 2012, an average decrease of 21% per year. The biggest decline in rate of infection was detected in 2008, which may suggest that the catheter-associated bloodstream infection prevention program was particularly effective. Among 4,478 surgical ICU admissions over the last 5 years, not a single case of methicillin-resistant S. aureus bacteremia was observed. Aggressive multifaceted horizontal infection control is an effective strategy for reducing the prevalence of methicillin-resistant S. aureus infection and eliminating methicillin-resistant S. aureus bacteremia in the ICU without the need for active surveillance and decontamination.

Endotoxemia and mortality prediction in ICU and other settings: underlying risk and co-detection of gram negative bacteremia are confounders

PubMed Central

2012-01-01

Introduction The interdependence between endotoxemia, gram negative (GN) bacteremia and mortality has been extensively studied. Underlying patient risk and GN bacteremia types are possible confounders of the relationship. Methods Published studies with ≥10 patients in either ICU or non-ICU settings, endotoxemia detection by limulus assay, reporting mortality proportions and ≥1 GN bacteremia were included. Summary odds ratios (OR) for mortality were derived across all studies by meta-analysis for the following contrasts: sub-groups with either endotoxemia (group three), GN bacteremia (group two) or both (group one) each versus the group with neither detected (group four; reference group). The mortality proportion for group four is the proxy measure of study level risk within L'Abbé plots. Results Thirty-five studies were found. Among nine studies in an ICU setting, the OR for mortality was borderline (OR <2) or non-significantly increased for groups two (GN bacteremia alone) and three (endotoxemia alone) and patient group one (GN bacteremia and endotoxemia co-detected) each versus patient group four (neither endotoxemia nor GN bacteremia detected). The ORs were markedly higher for group one versus group four (OR 6.9; 95% confidence interval (CI), 4.4 -to 11.0 when derived from non-ICU studies. The distributions of Pseudomonas aeruginosa and Escherichia coli bacteremias among groups one versus two are significantly unequal. Conclusions The co-detection of GN bacteremia and endotoxemia is predictive of increased mortality risk versus the detection of neither but only in studies undertaken in a non-ICU setting. Variation in GN bacteremia species types and underlying risk are likely unrecognized confounders in the individual studies. PMID:22871090

2013-01-01

Background And Objectives Nociceptin/Orphanin FQ (N/OFQ) is a non-classical endogenous opioid peptide that modulates immune function in vitro. Its importance in inflammation and human sepsis is unknown. The objectives of this study were to determine the relationship between N/OFQ, transcripts for its precursor (pre-pro-N/OFQ [ppNOC]) and receptor (NOP), inflammatory markers and clinical outcomes in patients undergoing cardiopulmonary bypass and with sepsis. Methods A prospective observational cohort study of 82 patients admitted to Intensive Care (ICU) with sepsis and 40 patients undergoing cardiac surgery under cardiopulmonary bypass (as a model of systemic inflammation). Sixty three healthy volunteers, matched by age and sex to the patients with sepsis were also studied. Clinical and laboratory details were recorded. Polymorph ppNOC and NOP receptor mRNA were determined using quantitative PCR. Plasma N/OFQ was determined using ELISA and cytokines (TNF- α, IL-8, IL-10) measured using radioimmunoassay. Data from patients undergoing cardiac surgery were recorded before, 3 and 24 hours after cardiopulmonary bypass. ICU patients with sepsis were assessed on Days 1 and 2 of ICU admission, and after clinical recovery. Main Results Plasma N/OFQ concentrations increased (p<0.0001) on Days 1 and 2 of ICU admission with sepsis compared to matched recovery samples. Polymorph ppNOC (p= 0.019) and NOP mRNA (p<0.0001) decreased compared to healthy volunteers. TNF-α, IL-8 and IL-10 concentrations increased on Day 1 compared to matched recovery samples and volunteers (p<0.0001). Similar changes (increased plasma N/OFQ, [p=0.0058], decreased ppNOC [p<0.0001], increased IL-8 and IL-10 concentrations [both p<0.0001]) occurred after cardiac surgery but these were comparatively lower and of shorter duration. Conclusions The N/OFQ system is modulated in ICU patients with sepsis with similar but reduced changes after cardiac surgery under cardiopulmonary bypass. Further studies are

We describe the importance of interprofessional care in modern critical care medicine. This review highlights the essential roles played by specific members of the interprofessional care team, including patients and family members, and discusses quality improvement initiatives that require interprofessional collaboration for success. Studies were identified through MEDLINE search using a variety of search phrases related to interprofessional care, critical care provider types, and quality improvement initiatives. Additional articles were identified through a review of the reference lists of identified articles. Original articles, review articles, and systematic reviews were considered. Manuscripts were selected for inclusion based on expert opinion of well-designed or key studies and review articles. "Interprofessional care" refers to care provided by a team of healthcare professionals with overlapping expertise and an appreciation for the unique contribution of other team members as partners in achieving a common goal. A robust body of data supports improvement in patient-level outcomes when care is provided by an interprofessional team. Critical care nurses, advanced practice providers, pharmacists, respiratory care practitioners, rehabilitation specialists, dieticians, social workers, case managers, spiritual care providers, intensivists, and nonintensivist physicians each provide unique expertise and perspectives to patient care, and therefore play an important role in a team that must address the diverse needs of patients and families in the ICU. Engaging patients and families as partners in their healthcare is also critical. Many important ICU quality improvement initiatives require an interprofessional approach, including Awakening and Breathing Coordination, Delirium, Early Exercise/Mobility, and Family Empowerment bundle implementation, interprofessional rounding practices, unit-based quality improvement initiatives, Patient and Family Advisory Councils

All 1,265 ICUs in 75 countries that contributed to the 1-day point prevalence Extended Prevalence of Infection in Intensive Care study. All adult patients present on a participating ICU on the study day. None. The Extended Prevalence of Infection in Intensive Care study included data on 13,796 adult patients. Organizational characteristics of the participating hospitals and units varied across geographic areas. Participating North American hospitals had greater availability of microbiologic examination and more 24-hour emergency departments than did the participating European and Latin American units. Of the participating ICUs, 82.9% were closed format, with the lowest prevalence among North American units (62.7%) and the highest in ICUs in Oceania (92.6%). The proportion of participating ICUs with 24-hour intensivist coverage was lower in North America than in Latin America (86.8% vs 98.1%, p = 0.002). ICU volume was significantly lower in participating ICUs from Western Europe, Latin America, and Asia compared with North America. In multivariable logistic regression analysis, medical and mixed ICUs were independently associated with a greater risk of in-hospital death. A nurse:patient ratio of more than 1:1.5 on the study day was independently associated with a lower risk of in-hospital death. In this international large cohort of ICU patients, hospital and ICU characteristics varied worldwide. A high nurse:patient ratio was independently associated with a lower risk of in-hospital death. These exploratory data need to be confirmed in large prospective studies that consider additional country-specific ICU practice variations.

Neonatal ICU research poses unique concerns for infants and parents. Children are considered a vulnerable research population. Federal regulations specify special protections when children participate in research. These regulations determine the types of research approvable for children based on the balance of risks and benefit. Risk also determines whether one or both parents' consent is required for their infant's participation in research.

Despite suggestions of potential harm from unnecessary oxygen therapy, critically ill patients spend substantial periods in a hyperoxemic state. A strategy of controlled arterial oxygenation is thus rational but has not been validated in clinical practice. To assess whether a conservative protocol for oxygen supplementation could improve outcomes in patients admitted to intensive care units (ICUs). Oxygen-ICU was a single-center, open-label, randomized clinical trial conducted from March 2010 to October 2012 that included all adults admitted with an expected length of stay of 72 hours or longer to the medical-surgical ICU of Modena University Hospital, Italy. The originally planned sample size was 660 patients, but the study was stopped early due to difficulties in enrollment after inclusion of 480 patients. Patients were randomly assigned to receive oxygen therapy to maintain Pao2 between 70 and 100 mm Hg or arterial oxyhemoglobin saturation (Spo2) between 94% and 98% (conservative group) or, according to standard ICU practice, to allow Pao2 values up to 150 mm Hg or Spo2 values between 97% and 100% (conventional control group). The primary outcome was ICU mortality. Secondary outcomes included occurrence of new organ failure and infection 48 hours or more after ICU admission. A total of 434 patients (median age, 64 years; 188 [43.3%] women) received conventional (n = 218) or conservative (n = 216) oxygen therapy and were included in the modified intent-to-treat analysis. Daily time-weighted Pao2 averages during the ICU stay were significantly higher (P < .001) in the conventional group (median Pao2, 102 mm Hg [interquartile range, 88-116]) vs the conservative group (median Pao2, 87 mm Hg [interquartile range, 79-97]). Twenty-five patients in the conservative oxygen therapy group (11.6%) and 44 in the conventional oxygen therapy group (20.2%) died during their ICU stay (absolute risk reduction [ARR], 0.086 [95% CI, 0.017-0.150]; relative risk [RR], 0

Verticalization was reported to improve the level of arousal and awareness in patients with severe acquired brain injury (ABI) and to be safe in ICU. We evaluated the effectiveness of a very early stepping verticalization protocol on their functional and neurological outcome. Consecutive patients with Vegetative State or Minimally Conscious State were enrolled in ICU on the third day after an ABI. They were randomized to undergo conventional physiotherapy alone or associated to fifteen 30-minute sessions of verticalization, using a tilt table with robotic stepping device. Once stabilized, patients were transferred to our Neurorehabilitation unit for an individualized treatment. Outcome measures (Glasgow Coma Scale, Coma Recovery Scale revised -CRSr-, Disability Rating Scale-DRS- and Levels of Cognitive Functioning) were assessed on the third day from the injury (T0), at ICU discharge (T1) and at Rehab discharge (T2). Between- and within-group comparisons were performed by the Mann-Whitney U test and Wilcoxon signed-rank test, respectively. Of the 40 patients enrolled, 31 completed the study without adverse events (15 in the verticalization group and 16 in the conventional physiotherapy). Early verticalization started 12.4±7.3 (mean±SD) days after ABI. The length of stay in ICU was longer for the verticalization group (38.8 ± 15.7 vs 25.1 ± 11.2 days, p = 0.01), while the total length of stay (ICU+Neurorehabilitation) was not significantly different (153.2 ± 59.6 vs 134.0 ± 61.0 days, p = 0.41). All outcome measures significantly improved in both groups after the overall period (T2 vs T0, p<0.001 all), as well as after ICU stay (T1 vs T0, p<0.004 all) and after Neurorehabilitation (T2 vs T1, p<0.004 all). The improvement was significantly better in the experimental group for CRSr (T2-T0 p = 0.033, T1-T0 p = 0.006) and (borderline) for DRS (T2-T0 p = 0.040, T1-T0 p = 0.058).

To quantify the time that intensive care unit registrars spend on different work tasks with other health professionals and patients and using information resources, and to compare them with those of clinicians in general wards and the emergency department (ED). A prospective, observational time-and-motion study of two ICUs with a total of 71 beds at two major teaching hospitals in Sydney. Twenty-six registrars were observed between 08:00 and 18:00 on weekdays for a total of 160.52 hours. Proportions of time spent on different tasks, using specific information resources, working with other health professionals and patients, and rates of multitasking and interruptions. A total of 12 043 distinct tasks were observed. Registrars spent 69.2% of time working at patients' bedsides, 49.6% in professional communication and 39.0% accessing information resources. Half of their time (53.8%) was spent with other ICU doctors and 29.2% with nurses. Compared with doctors and nurses on general wards, and doctors in the ED, ICU registrars were more likely to multitask (40.1 times/hour [24.4% of their time]). ICU registrars had a higher interruption rate than ward clinicians, (4.2 times/hour), but a lower rate than ED doctors. Face-to-face communication and information seeking consume a vast proportion of ICU registrars' time. Multitasking and handling frequent interruptions characterise their work, and such behaviours may create an increased risk of task errors. Electronic clinical information systems may be particularly beneficial in this information-rich environment.

Retrospective analysis of CPR quality in episodes of ER. Three independent board-certified emergency physicians trained in CPR and the American Heart Association (AHA) guidelines reviewed ER episodes in two 5-year time-frames (2001-2005 and 2005-2009). Congruency with the corresponding 2000 and 2005 AHA guidelines was determined for each CPR scene. None. None. To evaluate whether CPR is in agreement with the specific algorithms of the AHA guidelines. Fisher's exact test and Mann-Whitney-U-test were used to evaluate statistical significance (P<0.05). A total of 136 on-screen cardiac arrests occurred in 174 episodes. Trauma was the leading cause of cardiac arrest (56.6%), which was witnessed in 80.1%. Return of spontaneous circulation occurred in 38.2%. Altogether, 19.1% of patients survived until ICU admission, and 5.1% were discharged alive. Only one CPR scene was in agreement with the published AHA guidelines. However, low-quality CPR and non-compliance with the guidelines resulted in favorable outcomes.

A consecutive series of 129 patients with stroke (with infarction or intracerebral hemorrhage, 57 women and 72 men; mean age, 72.5 yrs; age range, 35-93 yrs) admitted to the stroke unit of a university hospital were evaluated for delirium incidence. None. Criterion validity and overall accuracy of the Czech version of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) were determined using serial daily delirium assessments with CAM-ICU by a junior physician compared with delirium diagnosis by delirium experts using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria that began the first day after stroke onset and continued for at least 7 days. Cox regression models using time-dependent covariate analysis adjusting for age, gender, prestroke dementia, National Institutes of Stroke Health Care at admission, first-day Sequential Organ Failure Assessment, and asphasia were used to understand the relationships between delirium and clinical outcomes. An episode of delirium based on reference Diagnostic and Statistical Manual assessment was detected in 55 patients with stroke (42.6%). In 37 of these (67.3%), delirium began within the first day and in all of them within 5 days of stroke onset. A total of 1003 paired CAM-ICU/Diagnostic and Statistical Manual of Mental Disorders daily assessments were completed. Compared with the reference standard for diagnosing delirium, the CAM-ICU demonstrated a sensitivity of 76% (95% confidence interval [CI] 55% to 91%), a specificity of 98% (95% CI 93% to 100%), an overall accuracy of 94% (95% CI 88% to 97%), and high interrater reliability (κ = 0.94; 95% CI 0

Acinetobacter baumannii constitutes a dreadful problem in many ICUs worldwide. The very limited therapeutic options available for these organisms are a matter of great concern. No specific guidelines exist addressing the prevention and management of A. baumannii infections in the critical care setting. Clinical microbiologists, infectious disease specialists and intensive care physicians were invited by the Chair of the Infection Section of the ESICM to participate in a multidisciplinary expert panel. After the selection of clinically relevant questions, this document provides recommendations about the use of microbiological techniques for identification of A. baumannii in clinical laboratories, antibiotic therapy for severe infections and recommendations to control this pathogen in outbreaks and endemic situations. Evidence supporting each statement was graded according to the European Society of Clinical Microbiology and Infection Diseases (ESCMID) grading system. Empirical coverage of A. baumannii is recommended in severe infections (severe sepsis or septic shock) occurring during an A. baumannii outbreak, in an endemic setting, or in a previously colonized patient. For these cases, a polymyxin is suggested as part of the empirical treatment in cases of a high suspicion of a carbapenem-resistant (CR) A. baumannii strain. An institutional program including staff education, promotion of hand hygiene, strict contact and isolation precautions, environmental cleaning, targeted active surveillance, and antimicrobial stewardship should be instituted and maintained to combat outbreaks and endemic situations. Specific recommendations about prevention and management of A. baumannii infections in the ICU were elaborated by this multidisciplinary panel. The paucity of randomized controlled trials is noteworthy, so these recommendations are mainly based on observational studies and pharmacodynamics modeling.

Intensive care unit (ICU) patients require dialysis catheters (DCs) for renal replacement therapy (RRT). They carry a high risk of developing end-stage renal disease, and therefore their vascular access must be preserved. Guidewire exchange (GWE) is often used to avoid venipuncture insertion (VPI) at a new site. However, the impact of GWE on infection and dysfunction of DCs in the ICU is unknown. Our aim was to compare the effect of GWE and VPI on DC colonization and dysfunction in ICU patients. Using data from the ELVIS randomized controlled trial (RCT) (1496 ICU adults requiring DC for RRT or plasma exchange) we performed a matched-cohort analysis. Cases were DCs inserted by GWE (n = 178). They were matched with DCs inserted by VPI. Matching criteria were participating centre, simplified acute physiology score (SAPS) II +/-10, insertion site (jugular or femoral), side for jugular site, and length of ICU stay before DC placement. We used a marginal Cox model to estimate the effect of DC insertion (GWE vs. VPI) on DC colonization and dysfunction. DC colonization rate was not different between GWE-DCs and VPI-DCs (10 (5.6 %) for both groups) but DC dysfunction was more frequent with GWE-DCs (67 (37.6 %) vs. 28 (15.7 %); hazard ratio (HR), 3.67 (2.07-6.49); p < 0.01). Results were similar if analysis was restricted to DCs changed for dysfunction. GWE for DCs in ICU patients, compared with VPI did not contribute to DC colonization or infection but was associated with more than twofold increase in DC dysfunction. This study is registered with ClinicalTrials.gov, number NCT00563342 . Registered 2 April 2009.

Practice guidelines are proliferating in medicine. In addition to methodological problems that cause guidelines to be outdated rapidly, they are plagued by conflicts of interest. They are largely consensus opinions of panels of experts, most of whom are supported by industry. Professional societies, health insurers, Centers for Medicare and Medicaid Services, and dialysis providers also benefit from guidelines. Little attention is paid to the potential for harm to patients, and to the profession of medicine, from the widespread use of guidelines. Copyright (c) 2007 S. Karger AG, Basel.

However, their application to biomedical text classification, particularly to mortality risk stratification among intensive care unit (ICU) patients, has not been thoroughly studied. To develop and characterize sparse classifiers based on the free text of nursing notes in order to predict ICU mortality risk and to discover text features most strongly associated with mortality. We selected nursing notes from the first 24h of ICU admission for 25,826 adult ICU patients from the MIMIC-II database. We then developed a pair of stochastic gradient descent-based classifiers with elastic-net regularization. We also studied the performance-sparsity tradeoffs of both classifiers as their regularization parameters were varied. The best-performing classifier achieved a 10-fold cross-validated AUC of 0.897 under the log loss function and full L2 regularization, while full L1 regularization used just 0.00025% of candidate input features and resulted in an AUC of 0.889. Using the log loss (range of AUCs 0.889-0.897) yielded better performance compared to the hinge loss (0.850-0.876), but the latter yielded even sparser models. Most features selected by both classifiers appear clinically relevant and correspond to predictors already present in existing ICU mortality models. The sparser classifiers were also able to discover a number of informative - albeit nonclinical - features. The elastic-net-regularized classifiers perform reasonably well and are capable of reducing the number of features required by over a thousandfold, with only a modest impact on performance.

The specific burden imposed on Intensive Care Units (ICUs) during the A/H1N1 influenza 2009 pandemic has been poorly explored. An on-line screening registry allowed a daily report of ICU beds occupancy rate by flu infected patients (Flu-OR) admitted in French ICUs. We conducted a prospective inception cohort study with results of an on-line screening registry designed for daily assessment of ICU burden. Among the 108 centers participating to the French H1N1 research network on mechanical ventilation (REVA) - French Society of Intensive Care (SRLF) registry, 69 ICUs belonging to seven large geographical areas voluntarily participated in a website screening-registry. The aim was to daily assess the ICU beds occupancy rate by influenza-infected and non-infected patients for at least three weeks. Three hundred ninety-one critically ill infected patients were enrolled in the cohort, representing a subset of 35% of the whole French 2009 pandemic cohort; 73% were mechanically ventilated, 13% required extra corporal membrane oxygenation (ECMO) and 22% died. The global Flu-OR in these ICUs was only 7.6%, but it exceeded a predefined 15% critical threshold in 32 ICUs for a total of 103 weeks. Flu-ORs were significantly higher in University than in non-University hospitals. The peak ICU burden was poorly predicted by observations obtained at the level of large geographical areas. The peak Flu-OR during the pandemic significantly exceeded a 15% critical threshold in almost half of the ICUs, with an uneven distribution with time, geographical areas and between University and non-University hospitals. An on-line assessment of Flu-OR via a simple dedicated registry may contribute to better match resources and needs.

Malabsorption, which is frequently underdiagnosed in critically ill patients, is clinically relevant with regard to nutritional balance and nutritional management. We aimed to validate the diagnostic accuracy of fecal weight as a biomarker for fecal loss and additionally to assess fecal macronutrient contents and intestinal absorption capacity in ICU patients. This was an observational pilot study in a tertiary mixed medical-surgical ICU in hemodynamically stable adult ICU patients, without clinically evident gastrointestinal malfunction. Fecal weight (grams/day), fecal energy (by bomb calorimetry in kcal/day), and macronutrient content (fat, protein, and carbohydrate in grams/day) were measured. Diagnostic accuracy expressed in terms of test sensitivity, specificity, positive (PPV) and negative predictive value (NPV), and receiver operator curves (ROCs) were calculated for fecal weight as a marker for energy malabsorption. Malabsorption was a priori defined as < 85% intestinal absorption capacity. Forty-eight patients (63 ± 15 years; 58% men) receiving full enteral feeding were included. A cut-off fecal production of > 350 g/day (that is, diarrhea) was linked to the optimal ROC (0.879), showing a sensitivity and PPV of 80%, respectively. Specificity and NPV were both 96%. Fecal weight (grams/day) and intestinal energy-absorption capacity were inversely correlated (r = -0.69; P < 0.001). Patients with > 350 g feces/day had a significantly more-negative energy balance compared with patients with < 350 g feces/day (loss of 627 kcal/day versus neutral balance; P = 0.012). A fecal weight > 350 g/day in ICU patients is a biomarker applicable in daily practice, which can act as a surrogate for fecal energy loss and intestinal energy absorption. Daily measurement of fecal weight is a feasible means of monitoring the nutritional status of critically ill patients and, in those identified as having malabsorption, can monitor responses to changes in dietary management.

To evaluate whether the Waterlow pressure sore risk (PSR) scale has prognostic significance for intensive care patients. A prospective study. The surgical intensive care unit (ICU) of the University Hospital Rotterdam. Data were evaluated from 594 patients who had been admitted to the ICU during the year 1994. Each patient was assessed daily with respect to their Waterlow PSR score and the development of pressure sores in the sacral region. Actuarial statistical methods were used to analyse the predictive value of the risk score. When a patient had a Waterlow PSR score > 25 on admission, the risk of developing a pressure sore was significantly increased compared to patients with a PSR score < 25. After admission, the daily Waterlow PSR scores obtained were significantly associated with the risk of developing a pressure sore. For each additional point this risk increased by 23% (95% confidence interval 17 to 28%). The Waterlow PSR scale provides the medical and nursing staff at an early stage with reliable information about the risk patients have in developing a pressure sore.

Prevention of ICU delirium and delirium-related outcome with haloperidol: a study protocol for a multicenter randomized controlled trial

PubMed Central

2013-01-01

Background Delirium is a frequent disorder in intensive care unit (ICU) patients with serious consequences. Therefore, preventive treatment for delirium may be beneficial. Worldwide, haloperidol is the first choice for pharmacological treatment of delirious patients. In daily clinical practice, a lower dose is sometimes used as prophylaxis. Some studies have shown the beneficial effects of prophylactic haloperidol on delirium incidence as well as on mortality, but evidence for effectiveness in ICU patients is limited. The primary objective of our study is to determine the effect of haloperidol prophylaxis on 28-day survival. Secondary objectives include the incidence of delirium and delirium-related outcome and the side effects of haloperidol prophylaxis. Methods This will be a multicenter three-armed randomized, double-blind, placebo-controlled, prophylactic intervention study in critically ill patients. We will include consecutive non-neurological ICU patients, aged ≥18 years with an expected ICU length of stay >1 day. To be able to demonstrate a 15% increase in 28-day survival time with a power of 80% and alpha of 0.05 in both intervention groups, a total of 2,145 patients will be randomized; 715 in each group. The anticipated mortality rate in the placebo group is 12%. The intervention groups will receive prophylactic treatment with intravenous haloperidol 1 mg/q8h or 2 mg/q8h, and patients in the control group will receive placebo (sodium chloride 0.9%), both for a maximum period of 28-days. In patients who develop delirium, study medication will be stopped and patients will subsequently receive open label treatment with a higher (therapeutic) dose of haloperidol. We will use descriptive summary statistics as well as Cox proportional hazard regression analyses, adjusted for covariates. Discussion This will be the first large-scale multicenter randomized controlled prevention study with haloperidol in ICU patients with a high risk of delirium, adequately

Pandemic Influenza A (H1N1)v infection is the first pandemic in which intensive care units (ICU) play a fundamental role. It has spread very rapidly since the first cases were diagnosed in Mexico with the subsequent spread of the virus throughout the Southern Cone and Europe during the summer season. This study has aimed to compare the clinical presentation and outcome among the critical patients admitted to the ICU until July 31, 2009 in Spain with some series from Latin America. Six series of critically ill patients admitted to the ICU were considered. Clinical characteristics, complications and outcome were compared between series. Young patients (35-45 years) with viral pneumonia as a predominant ICU admission cause with severe respiratory failure and a high need of mechanical ventilation (60-100%) were affected. Obesity, pregnancy and chronic lung disease were risk factors associated with a worse outcome, however there was a high number of patients without comorbidities (40-50%). Mortality rate was between 25-50% and higher in the Latin America series, demonstrating the specific potential pathogenesis of the new virus. The use of antiviral treatment was delayed (between 3 and 6 days) and not generalized, with greater delay in Latin America in regards to Spain. These data suggest that a more aggressive treatment strategy, with earlier and easier access to the antiviral treatment might reduce the number of ICU admissions and mortality.

Literature depicts differences in ethical decision-making (EDM) between countries and intensive care units (ICU). To better conceptualise EDM climate in the ICU and to validate a tool to assess EDM climates. Using a modified Delphi method, we built a theoretical framework and a self-assessment instrument consisting of 35 statements. This Ethical Decision-Making Climate Questionnaire (EDMCQ) was developed to capture three EDM domains in healthcare: interdisciplinary collaboration and communication; leadership by physicians; and ethical environment. This instrument was subsequently validated among clinicians working in 68 adult ICUs in 13 European countries and the USA. Exploratory and confirmatory factor analysis was used to determine the structure of the EDM climate as perceived by clinicians. Measurement invariance was tested to make sure that variables used in the analysis were comparable constructs across different groups. Of 3610 nurses and 1137 physicians providing ICU bedside care, 2275 (63.1%) and 717 (62.9%) participated respectively. Statistical analyses revealed that a shortened 32-item version of the EDMCQ scale provides a factorial valid measurement of seven facets of the extent to which clinicians perceive an EDM climate: self-reflective and empowering leadership by physicians; practice and culture of open interdisciplinary reflection; culture of not avoiding end-of-life decisions; culture of mutual respect within the interdisciplinary team; active involvement of nurses in end-of-life care and decision-making; active decision-making by physicians; and practice and culture of ethical awareness. Measurement invariance of the EDMCQ across occupational groups was shown, reflecting that nurses and physicians interpret the EDMCQ items in a similar manner. The 32-item version of the EDMCQ might enrich the EDM climate measurement, clinicians' behaviour and the performance of healthcare organisations. This instrument offers opportunities to develop tailored ICU

Objectives: The “Pneumonia Zero” project is a nationwide multimodal intervention based on the simultaneous implementation of a comprehensive evidence-based bundle measures to prevent ventilator-associated pneumonia in critically ill patients admitted to the ICU. Design: Prospective, interventional, and multicenter study. Setting: A total of 181 ICUs throughout Spain. Patients: All patients admitted for more than 24 hours to the participating ICUs between April 1, 2011, and December 31, 2012. Intervention: Ten ventilator-associated pneumonia prevention measures were implemented (seven were mandatory and three highly recommended). The database of the National ICU-Acquired Infections Surveillance Study (Estudio Nacional de Vigilancia de Infecciones Nosocomiales [ENVIN]) was used for data collection. Ventilator-associated pneumonia rate was expressed as incidence density per 1,000 ventilator days. Ventilator-associated pneumonia rates from the incorporation of the ICUs to the project, every 3 months, were compared with data of the ENVIN registry (April–June 2010) as the baseline period. Ventilator-associated pneumonia rates were adjusted by characteristics of the hospital, including size, type (public or private), and teaching (postgraduate) or university-affiliated (undergraduate) status. Measurements and Main Results: The 181 participating ICUs accounted for 75% of all ICUs in Spain. In a total of 171,237 ICU admissions, an artificial airway was present on 505,802 days (50.0% of days of stay in the ICU). A total of 3,474 ventilator-associated pneumonia episodes were diagnosed in 3,186 patients. The adjusted ventilator-associated pneumonia incidence density rate decreased from 9.83 (95% CI, 8.42–11.48) per 1,000 ventilator days in the baseline period to 4.34 (95% CI, 3.22–5.84) after 19–21 months of participation. Conclusions: Implementation of the bundle measures included in the “Pneumonia Zero” project resulted in a significant reduction of more than

This study aimed at analyzing the family participation in the premature assistance in a university hospital neonatal ICU. Data were collected from the participant observation. Results showed that despite of the mother's presence in the daily life of their premature children placed in a hospital, family isn't inserted in the work process and mothers are the only ones who take part of the cares. This participation basically happens in the execution of maternity care, especially at the medium risk unity, the mother and premature family are less welcomed and there isn't any partnership between the care team and the family, there aren't team interventions in order to turn premature family in autonomous subject to promote health and life quality to baby's life.

Audit and feedback is integral to performance improvement and behaviour change in the intensive care unit (ICU). However, there remain large gaps in our understanding of the social experience of audit and feedback and the mechanisms whereby it can be optimised as a quality improvement strategy in the ICU setting. We conducted a modified grounded theory qualitative study. Seventy-two clinicians from five academic and five community ICUs in Ontario, Canada, were interviewed. Team members reviewed interview transcripts independently. Data analysis used constant comparative methods. Clinicians interviewed experienced audit and feedback as fragmented and variable in its effectiveness. Moreover, clinicians felt disconnected from the process. The audit process was perceived as being insufficiently transparent. Feedback was often untimely, incomplete and not actionable. Specific groups such as respiratory therapists and night-shift clinicians felt marginalised. Suggestions for improvement included improving information sharing about the rationale for change and the audit process, tools and metrics; implementing peer-to-peer quality discussions to avoid a top-down approach (eg, incorporating feedback into discussions at daily rounds); providing effective feedback which contains specific, transparent and actionable information; delivering timely feedback (ie, balancing feedback proximate to events with trends over time) and increasing engagement by senior management. ICU clinicians experience audit and feedback as fragmented communication with feedback being especially problematic. Attention to improving communication, integration of the process into daily clinical activities and making feedback timely, specific and actionable may increase the effectiveness of audit and feedback to affect desired change.

Endotracheal intubation using the C-MAC® video laryngoscope or the Macintosh laryngoscope: A prospective, comparative study in the ICU

PubMed Central

2012-01-01

Introduction Endotracheal intubation in the ICU is a challenging procedure and is frequently associated with life-threatening complications. The aim of this study was to investigate the effect of the C-MAC® video laryngoscope on laryngeal view and intubation success compared with direct laryngoscopy. Methods In a single-center, prospective, comparative before-after study in an anesthetist-lead surgical ICU of a tertiary university hospital, predictors of potentially difficult tracheal intubation, number of intubation attempts, success rate and glottic view were evaluated during a 2-year study period (first year, Macintosh laryngoscopy (ML); second year, C-MAC®). Results A total of 274 critically ill patients requiring endotracheal intubation were included; 113 intubations using ML and 117 intubations using the C-MAC® were assessed. In patients with at least one predictor for difficult intubation, the C-MAC® resulted in more successful intubations on first attempt compared with ML (34/43, 79% vs. 21/38, 55%; P = 0.03). The visualization of the glottis with ML using Cormack and Lehane (C&L) grading was more frequently rated as difficult (20%, C&L grade 3 and 4) compared with the C-MAC® (7%, C&L grade 3 and 4) (P < 0.0001). Conclusion Use of the C-MAC® video laryngoscope improved laryngeal imaging and improved the intubating success rate on the first attempt in patients with predictors for difficult intubation in the ICU setting. Video laryngoscopy seems to be a useful tool in the ICU where potentially difficult endotracheal intubations regularly occur. PMID:22695007

Daytime intensivist physician staffing is associated with improved outcomes in the ICU. However, it is unclear whether this association persists in the era of interprofessional, protocol-directed critical care. We sought to reexamine the association between daytime intensivist physician staffing and ICU mortality and determine if interprofessional rounding and protocols for mechanical ventilation in part mediate this relationship. Retrospective cohort study of ICUs in the Acute Physiology and Chronic Health Evaluation clinical information system from 2009 to 2010. Forty-nine ICUs in 25 U.S. hospitals. Adults (17 yr and older) admitted to a study ICU. None. We defined high-intensity daytime intensivist staffing as either a mandatory consult or closed ICU model; interprofessional rounds as rounds that included a respiratory therapist, pharmacist, physician and nurse; and protocol use as having protocols for liberation from mechanical ventilation and lung protective mechanical ventilation. Using multivariable logistic regression, we estimated the independent effect of daytime intensivist physician staffing on in-hospital mortality controlling for interprofessional rounds and protocols for mechanical ventilation, as well as other patient and hospital characteristics. Twenty-seven ICUs (55%) reported high-intensity daytime physician staffing, 42 ICUs (85%) reported daily interprofessional rounds, and 31 (63%) reported having protocols for mechanical ventilation. There was no association between daytime intensivist physician staffing and in-hospital mortality (adjusted odds ratio, 0.86; 95% CI, 0.65-1.14). After adjusting for interprofessional rounds and protocols for mechanical ventilation, the effect of daytime intensivist physician staffing remained nonsignificant (adjusted odds ratio, 0.90; 95% CI, 0.70-1.17). High-intensity daytime physician staffing in the ICU was not significantly associated with lower mortality in a modern cohort. This association was not

These tools have not been tested in a specialized cardio-surgical ICU. Sensitivities and specificities of each tool were assessed in a cardio-surgical ICU in Japan by two trained nurses independently. Results were compared with delirium diagnosed by psychiatrists using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision. There were 110 daily, paired assessments in 31 patients. The CAM-ICU showed 38% sensitivity and 100% specificity for both nurses. All 20 false-negative cases resulted from high scores in the auditory attention screening in CAM-ICU. The ICDSC showed 97% and 94% sensitivity, and 97% and 91% specificity for the two nurses (cutoff ≥4). In a Japanese cardio-surgical ICU, the ICDSC had a higher sensitivity than the CAM-ICU.

Background and Objective Verticalization was reported to improve the level of arousal and awareness in patients with severe acquired brain injury (ABI) and to be safe in ICU. We evaluated the effectiveness of a very early stepping verticalization protocol on their functional and neurological outcome. Methods Consecutive patients with Vegetative State or Minimally Conscious State were enrolled in ICU on the third day after an ABI. They were randomized to undergo conventional physiotherapy alone or associated to fifteen 30-minute sessions of verticalization, using a tilt table with robotic stepping device. Once stabilized, patients were transferred to our Neurorehabilitation unit for an individualized treatment. Outcome measures (Glasgow Coma Scale, Coma Recovery Scale revised -CRSr-, Disability Rating Scale–DRS- and Levels of Cognitive Functioning) were assessed on the third day from the injury (T0), at ICU discharge (T1) and at Rehab discharge (T2). Between- and within-group comparisons were performed by the Mann-Whitney U test and Wilcoxon signed-rank test, respectively. Results Of the 40 patients enrolled, 31 completed the study without adverse events (15 in the verticalization group and 16 in the conventional physiotherapy). Early verticalization started 12.4±7.3 (mean±SD) days after ABI. The length of stay in ICU was longer for the verticalization group (38.8 ± 15.7 vs 25.1 ± 11.2 days, p = 0.01), while the total length of stay (ICU+Neurorehabilitation) was not significantly different (153.2 ± 59.6 vs 134.0 ± 61.0 days, p = 0.41). All outcome measures significantly improved in both groups after the overall period (T2 vs T0, p<0.001 all), as well as after ICU stay (T1 vs T0, p<0.004 all) and after Neurorehabilitation (T2 vs T1, p<0.004 all). The improvement was significantly better in the experimental group for CRSr (T2-T0 p = 0.033, T1-T0 p = 0.006) and (borderline) for DRS (T2-T0 p = 0.040, T1-T0 p = 0.058).

Limited data are available describing the clinical presentation and risk factors for admission to the intensive care unit for children with 2009 H1N1 infection. We conducted a retrospective chart review of all hospitalized children with 2009 influenza A (H1N1) and 2008-09 seasonal influenza at The Children's Hospital, Denver, Colorado. Of the 307 children identified with 2009 H1N1 infections, the median age was 6 years, 61% were male, and 66% had underlying medical conditions. Eighty children (26%) were admitted to the ICU. Thirty-two (40%) of the ICU patients required intubation and 17 (53%) of the intubated patients developed acute respiratory distress syndrome (ARDS). Four patients required extracorporeal membrane oxygenation. Eight (3%) of the hospitalized children died. Admission to the ICU was significantly associated with older age and underlying neurological condition. Compared to the 90 children admitted during the 2008-09 season, children admitted with 2009 H1N1 influenza were significantly older, had a shorter length of hospitalization, more use of antivirals, and a higher incidence of ARDS. Compared to the 2008-09 season, hospitalized children with 2009 H1N1 influenza were much older and had more severe respiratory disease. Among children hospitalized with 2009 H1N1 influenza, risk factors for admission to the ICU included older age and having an underlying neurological condition. Children under the age of 2 hospitalized with 2009 H1N1 influenza were significantly less likely to require ICU care compared to older hospitalized children.

Although the ICU is the most appropriate place to care for mechanically ventilated patients, a considerable number are ventilated in general medical care wards all over the world. However, adverse events focusing on mechanically ventilated patients in general care have not been explored. Data from the Japan Council for Quality Health Care database were analyzed. Patient safety incidents from January 2010 to November 2017 regarding mechanical ventilation were collected, and comparisons of patient safety incidents between ICUs/high care units (HCUs) and general care wards were made. We identified 261 adverse events (with at least 20 adverse events resulting in death) and 702 near-miss events related to mechanical ventilation in Japan between 2010 and 2017. Furthermore, among all adverse events, 19% (49 of 261 events) caused serious harm (residual disability or death). Human-factor issues were most frequent in both ICU/HCU and general care settings (55% and 53%, respectively), while knowledge-based errors were higher in the general care setting. Human-factor issues were the most frequent reasons in both settings, while knowledge-based error rates were higher in general care. Our results suggest that proper education and training is needed to minimize patient safety incidents in facilities without respiratory therapists. Copyright © 2018 by Daedalus Enterprises.

To examine the association between statin use and the risk of delirium in hospitalized patients with an admission to the medical ICU. Retrospective propensity-matched cohort analysis with accrual from September 1, 2012, to September 30, 2015. Hartford Hospital, Hartford, CT. An initial population of patients with an admission to a medical ICU totaling 10,216 visits were screened for delirium by means of the Confusion Assessment Method. After exclusions, a population of 6,664 was used to match statin users and nonstatin users. The propensity-matched cohort resulted in a sample of 1,475 patients receiving statin matched 1:1 with control patients not using statin. None. Delirium defined as a positive Confusion Assessment Method assessment was the primary end point. The prevalence of delirium was 22.3% in the unmatched cohort and 22.8% in the propensity-matched cohort. Statin use was associated with a significant decrease in the risk of delirium (odds ratio, 0.47; 95% CI, 0.38-0.56). Considering the type of statin used, atorvastatin (0.51; 0.41-0.64), pravastatin (0.40; 0.28-0.58), and simvastatin (0.33; 0.21-0.52) were all significantly associated with a reduced frequency of delirium. The use of statins was independently associated with a reduction in the risk of delirium in hospitalized patients. When considering types of statins used, this reduction was significant in patients using atorvastatin, pravastatin, and simvastatin. Randomized trials of various statin types in hospitalized patients prone to delirium should validate their use in protection from delirium.

Background Little is known about homeless patients in intensive care units (ICUs). Objectives To compare clinical characteristics, treatments, and outcomes of homeless to non-homeless patients admitted to four ICUs in a large inner-city academic hospital. Methods 63 randomly-selected homeless compared to 63 age-, sex-, and admitting-ICU-matched non-homeless patients. Results Compared to matched non-homeless, homeless patients (average age 48±12 years, 90% male, 87% admitted by ambulance, 56% mechanically ventilated, average APACHE II 17) had similar comorbidities and illness severity except for increased alcohol (70% vs 17%,p<0.001) and illicit drug(46% vs 8%,p<0.001) use and less documented hypertension (16% vs 40%,p = 0.005) or prescription medications (48% vs 67%,p<0.05). Intensity of ICU interventions was similar except for higher thiamine (71% vs 21%,p<0.0001) and nicotine (38% vs 14%,p = 0.004) prescriptions. Homeless patients exhibited significantly lower Glasgow Coma Scores and significantly more bacterial respiratory cultures. Longer durations of antibiotics, vasopressors/inotropes, ventilation, ICU and hospital lengths of stay were not statistically different, but homeless patients had higher hospital mortality (29% vs 8%,p = 0.005). Review of all deaths disclosed that withdrawal of life-sustaining therapy occurred in similar clinical circumstances and proportions in both groups, regardless of family involvement. Using multivariable logistic regression, homelessness did not appear to be an independent predictor of hospital mortality. Conclusions Homeless patients, admitted to ICU matched to non-homeless patients by age and sex (characteristics most commonly used by clinicians), have higher hospital mortality despite similar comorbidities and illness severity. Trends to longer durations of life supports may have contributed to the higher mortality. Additional research is required to validate this higher mortality and develop strategies to improve outcomes

Tracheostomy is a common surgical procedure performed in long-term ventilated patients in intensive care. Since the role of percutaneous dilatational tracheostomy (PDT) on Intensive Care Unit (ICU) has become steadily more important in the last few years, a prospective study was started to evaluate the economic efficiency and to show the minimization of the complication rate of this procedure. In 72 patients we performed PDT as a bedside procedure. Initially the thyroid gland and the subcutaneous vessels were studied by ultrasound in every patient. The puncture of the trachea, the dilatational procedure and the insertion of the tracheal cannula were executed under bronchoscopic monitoring. Finally, a bronchoscopic control view followed via the new cannula to detect intratracheal complications. Mechanical ventilation was maintained during the procedure and controlled by continuous pulse oximetry. According to prior ultrasound findings the place to puncture the trachea was changed in 24% of the patients, in one case tracheostomy was performed as an open conventional procedure. The following complications could be observed: one case involving perforation of a cartilaginous ring, one case with venous bleeding of a small subcutaneous vein and two cases with punctures of the bronchoscope. There were no cases of miscannulation, penetration of the posterior tracheal wall or major bleeding requiring intervention or conversion. The followup study revealed that there was no sign of further complications in any patient. In addition, cost analysis demonstrated that there was a significant economical advantage of PDT in comparison with open standard tracheostomy. Standardized ultrasonographically and bronchoscopically controlled PDT turns out to be a safe, simple and cost effective bedside procedure on ICU. Because of ultrasound examination performed before the procedure, and bronchoscopic surveillance during the procedure, safety of this procedure can be enhanced, thus

Variable-Domain Functional Regression for Modeling ICU Data.

2014-12-01

We introduce a class of scalar-on-function regression models with subject-specific functional predictor domains. The fundamental idea is to consider a bivariate functional parameter that depends both on the functional argument and on the width of the functional predictor domain. Both parametric and nonparametric models are introduced to fit the functional coefficient. The nonparametric model is theoretically and practically invariant to functional support transformation, or support registration. Methods were motivated by and applied to a study of association between daily measures of the Intensive Care Unit (ICU) Sequential Organ Failure Assessment (SOFA) score and two outcomes: in-hospital mortality, and physical impairment at hospital discharge among survivors. Methods are generally applicable to a large number of new studies that record a continuous variables over unequal domains.

Effort-Reward Imbalance and Burnout Among ICU Nursing Staff: A Cross-Sectional Study.

PubMed

Padilla Fortunatti, Cristobal; Palmeiro-Silva, Yasna K

Occupational stress is commonly observed among staff in intensive care units (ICUs). Sociodemographic, organizational, and job-related factors may lead to burnout among ICU health workers. In addition, these factors could modify the balance between efforts done and rewards perceived by workers; consequently, this imbalance could increase levels of emotional exhaustion and depersonalization and decrease a sense of personal accomplishment. The purpose of this study was to analyze the relationship between effort-reward imbalance and burnout dimensions (emotional exhaustion, depersonalization, and personal accomplishment) among ICU nursing staff in a university hospital in Santiago, Chile. A convenience sample of 36 registered nurses and 46 nurse aides answered the Maslach Burnout Inventory and Effort-Reward Imbalance Questionnaire and provided sociodemographic and work-related data. Age and effort-reward imbalance were significantly associated with emotional exhaustion in both registered nurses and nurse aides; age was negatively correlated with emotional exhaustion, whereas effort-reward imbalance was positively correlated. Age was negatively associated with depersonalization. None of the predictors were associated with personal accomplishment. This study adds valuable information about relationships of sociodemographic factors and effort-reward imbalance and their impact on dimensions of burnout, particularly on emotional exhaustion.

Source of infection is an independent predictor of sepsis-related mortality. To date, studies have failed to evaluate differences in septic patients based on the source of infection. Retrospective study of all patients with sepsis admitted to the ICU of a university hospital within a 12month time period. Sepsis due to intravascular device and multiple sources had the highest number of positive blood cultures and microbiology whereas lung and abdominal sepsis had the least. The observed hospital mortality was highest for sepsis due to multiple sources and unknown cause, and was lowest when due to abdominal, genitourinary (GU) or skin/soft tissue. Patients with sepsis due to lungs, unknown and multiple sources had the highest rates of multi-organ failure, whereas those with sepsis due to GU and skin/soft tissue had the lowest rates. Those with multisource sepsis had a significantly higher median ICU length of stay and hospital cost. There are significant differences in patient characteristics, microbiology positivity, organs affected, mortality, length of stay and cost based on the source of sepsis. These differences should be considered in future studies to be able to deliver personalized care. Copyright © 2017 Elsevier Inc. All rights reserved.

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.

The Intensive Care Unit (ICU) is an extremely data-intensive environment where each patient needs to be monitored 24/7. Bedside monitors continuously register vital patient values (such as serum creatinine, systolic blood pressure) which are recorded frequently in the hospital database (e.g. every 2 min in the ICU of the Ghent University Hospital), laboratories generate hundreds of results of blood and urine samples, and nurses measure blood pressure and temperature up to 4 times an hour. The processing of such large amount of data requires an automated system to support the physicians' daily work. The Intensive Care Service Platform (ICSP) offers the needed support through the development of medical support services for processing and monitoring patients' data. With an increased deployment of these medical support services, reusing existing services as building blocks to create new services offers flexibility to the developer and accelerates the design process. This paper presents a new addition to the ICSP, the Dynamic Composer for Web services. Based on a semantic description of the medical support services, this Composer enables a service to be executed by creating a composition of medical services that provide the needed calculations. The composition is achieved using various algorithms satisfying certain quality of service (QoS) constraints and requirements. In addition to the automatic composition the paper also proposes a recovery mechanism in case of unavailable services. When executing the composition of medical services, unavailable services are dynamically replaced by equivalent services or a new composition achieving the same result. The presented platform and QoS algorithms are put through extensive performance and scalability tests for typical ICU scenarios, in which basic medical services are composed to a complex patient monitoring service.

The establishment of early warning systems in hospitals was strongly recommended in recent guidelines to detect deteriorating patients early and direct them to adequate care. Upon reaching predefined trigger criteria, Medical Emergency Teams (MET) should be notified and directed to these patients. The present study analyses the effect of introducing an automated multiparameter early warning score (MEWS)-based early warning system with paging functionality on 2 wards hosting patients recovering from highly complex surgical interventions. The deployment of the system was accompanied by retrospective data acquisition during 12 months (intervention) using 4 routine databases: Hospital patient data management, anesthesia database, local data of the German Resuscitation Registry, and measurement logs of the deployed system (intervention period only). A retrospective 12-month data review using the same aforementioned databases before the deployment of the system served as control. Control and intervention phases were separated by a 6-month washout period for the installation of the system and for training. Data from 3827 patients could be acquired from 2 surgical wards during the two 12-month periods, 1896 patients in the control and 1931 in the intervention cohorts. Patient characteristics differed between the 2 observation phases. American Society of Anesthesiologists risk classification and duration of surgery as well as German DRG case-weight were significantly higher in the intervention period. However, the rate of cardiac arrests significantly dropped from 5.3 to 2.1 per 1000 admissions in the intervention period (P < 0.001). This observation was paralleled by a reduction of unplanned ICU admissions from 3.6% to 3.0% (P < 0.001), and an increase of notifications of critical conditions to the ward surgeon. The primary triggers for MET activation were abnormal ECG alerts, specifically asystole (n = 5), and pulseless electric activity (n = 8). In concert with a well

Chest X-rays (CXRs) are traditionally obtained daily in all patients on invasive mechanical ventilation (IMV) in the intensive care unit (ICU). We sought to reduce overutilisation of CXRs obtained in the ICU, using a multifaceted intervention to eliminate automated daily studies. We first educated ICU staff about the low diagnostic yield of automated daily CXRs, then removed the 'daily' option from the electronic health records-based ordering system, and added a query (CXR indicated or not indicated) to the ICU daily rounding checklist to prompt a CXR order when clinically warranted. We built a report from billing codes, focusing on all CXRs obtained on IMV census days in the medical (MICU) and surgical (SICU) ICUs, excluding the day of admission and days that a procedure warranting CXR was performed. This generated the number of CXRs obtained every 1000 'included' ventilator days (IVDs), the latter defined as not having an 'absolute' clinical indication for CXR. The average monthly number of CXRs on an IVD decreased from 919±90 (95% CI 877 to 963) to 330±87 (95% CI 295 to 354) per 1000 IVDs in the MICU, and from 995±69 (95% CI 947 to 1055) to 649±133 (95% CI 593 to 697) in the SICU. This yielded an estimated 1830 to 2066 CXRs avoided over 2 years and an estimated annual savings of $191 600 to $224 200. There was no increase in reported adverse events. ICUs can safely transition to a higher value strategy of indication-based chest imaging by educating staff, eliminating the 'daily' order option and adding a simplified prompt to avoid missing clinically indicated CXRs.

Introduction of neurocritical care services to dedicated neuro-ICUs is associated with improved quality of care. The impact of a neurocritical care service without a dedicated neuro-ICU has not been studied. We retrospectively identified all patients admitted to our institution with intracerebral hemorrhage (ICH) in two 12-month periods: immediately before the arrival of the first neurointensivist ("before") and after the neurocritical care service was established ("after"). There was no nursing team, ICU housestaff/physician extender team, or physical unit dedicated to the care of patients with critical neurologic illness during either period. Using an uncontrolled before-after design, we compared clinical outcomes and performance on quality metrics between groups. We included 74 patients with primary supratentorial ICH. Mortality, length of stay (LOS), proportion of patients with modified Rankin Score 0-3, and destination on discharge did not differ between groups when adjusted for confounders. Time to first two consecutive systolic blood pressure (SBP) measurements <180 mmHg was shorter in the "after" cohort (mean 4.5 vs. 3.2 h, p = 0.001). Area under the curve measurement for change in SBP from baseline over the first 24 h after ED arrival demonstrated greater, sustained SBP reduction in the "after" cohort (mean -187.9 vs. -720.9, p = 0.04). A higher proportion of patients were fed without passing a dysphagia screen in the "before" group (45 vs. 0%, p < 0.001). Introduction of a neurocritical service without a neuro-ICU at our institution was associated with a trend toward longer ICU LOS and improvement in some key metrics of quality of care for patients with ICH.

To determine if a video depicting cardiopulmonary resuscitation and resuscitation preference options would improve knowledge and decision making among patients and surrogates in the ICU. Randomized, unblinded trial. Single medical ICU. Patients and surrogate decision makers in the ICU. The usual care group received a standard pamphlet about cardiopulmonary resuscitation and cardiopulmonary resuscitation preference options plus routine code status discussions with clinicians. The video group received usual care plus an 8-minute video that depicted cardiopulmonary resuscitation, showed a simulated hospital code, and explained resuscitation preference options. One hundred three patients and surrogates were randomized to usual care. One hundred five patients and surrogates were randomized to video plus usual care. Median total knowledge scores (0-15 points possible for correct answers) in the video group were 13 compared with 10 in the usual care group, p value of less than 0.0001. Video group participants had higher rates of understanding the purpose of cardiopulmonary resuscitation and resuscitation options and terminology and could correctly name components of cardiopulmonary resuscitation. No statistically significant differences in documented resuscitation preferences following the interventions were found between the two groups, although the trial was underpowered to detect such differences. A majority of participants felt that the video was helpful in cardiopulmonary resuscitation decision making (98%) and would recommend the video to others (99%). A video depicting cardiopulmonary resuscitation and explaining resuscitation preference options was associated with improved knowledge of in-hospital cardiopulmonary resuscitation options and cardiopulmonary resuscitation terminology among patients and surrogate decision makers in the ICU, compared with receiving a pamphlet on cardiopulmonary resuscitation.

Mortality prediction scores are widely used in intensive care units (ICUs) and in research, but their predictive value deteriorates as scores age. Existing mortality prediction scores are imprecise and complex, which increases the risk of missing data and decreases the applicability bedside in daily clinical practice. We propose the development and validation of a new, simple and updated clinical prediction rule: the Simplified Mortality Score for use in the Intensive Care Unit (SMS-ICU). During the first phase of the study, we will develop and internally validate a clinical prediction rule that predicts 90-day mortality on ICU admission. The development sample will comprise 4247 adult critically ill patients acutely admitted to the ICU, enrolled in 5 contemporary high-quality ICU studies/trials. The score will be developed using binary logistic regression analysis with backward stepwise elimination of candidate variables, and subsequently be converted into a point-based clinical prediction rule. The general performance, discrimination and calibration of the score will be evaluated, and the score will be internally validated using bootstrapping. During the second phase of the study, the score will be externally validated in a fully independent sample consisting of 3350 patients included in the ongoing Stress Ulcer Prophylaxis in the Intensive Care Unit trial. We will compare the performance of the SMS-ICU to that of existing scores. We will use data from patients enrolled in studies/trials already approved by the relevant ethical committees and this study requires no further permissions. The results will be reported in accordance with the Transparent Reporting of multivariate prediction models for Individual Prognosis Or Diagnosis (TRIPOD) statement, and submitted to a peer-reviewed journal.

To investigate a progressive mobility program in a neurocritical care population with the hypothesis that the benefits and outcomes of the program (e.g., decreased length of stay) would have a significant positive economic impact. Retrospective analysis of economic and clinical outcome data before, immediately following, and 2 years after implementation of the Progressive Upright Mobility Protocol Plus program (UF Health Shands Hospital, Gainesville, FL) involving a series of planned movements in a sequential manner with an additional six levels of rehabilitation in the neuro-ICU at UF Health Shands Hospital. Thirty-bed neuro-ICU in an academic medical center. Adult neurologic and neurosurgical patients: 1,118 patients in the pre period, 731 patients in the post period, and 796 patients in the sustained period. Implementation of Progressive Upright Mobility Protocol Plus. ICU length of stay decreased from 6.5 to 5.8 days in the immediate post period and 5.9 days in the sustained period (F(2,2641) = 3.1; p = 0.045). Hospital length of stay was reduced from 11.3 ± 14.1 days to 8.6 ± 8.8 post days and 8.8 ± 9.3 days sustained (F(2,2641) = 13.0; p < 0.001). The impact of the study intervention on ICU length of stay (p = 0.031) and hospital length of stay (p < 0.001) remained after adjustment for age, sex, diagnoses, sedation, and ventilation. Hospital-acquired infections were reduced by 50%. Average total cost per patient after adjusting for inflation was significantly reduced by 16% (post period) and 11% (sustained period) when compared with preintervention (F(2,2641) = 3.1; p = 0.045). Overall, these differences translated to an approximately $12.0 million reduction in direct costs from February 2011 through the end of 2013. An ongoing progressive mobility program in the neurocritical care population has clinical and financial benefits associated with its implementation and should be considered.

This study analyzed occupational health hazards for Intensive Care Unit (ICU) nurses and nursing technicians, comparing differences in the number and types of hazards which occur at the beginning and end of their careers. A descriptive cross-sectional study was carried out with 26 nurses and 96 nursing technicians from a public hospital in the Federal District, Brazil. A Likert-type work-related symptom scale (WRSS) was used to evaluate the presence of physical, psychological, and social risks. Data were analyzed with the use of the SPSS, version 12.0, and the Kruskal-Wallis test for statistical significance and differences in occupational health hazards at the beginning and at the end of the workers' careers. As a workplace, ICUs can cause work health hazards, mostly physical, to nurses and nursing technicians due to the frequent use of physical energy and strength to provide care, while psychological and social hazards occur to a lesser degree.

Left ventricular diastolic dysfunction is suggested to be associated with higher mortality in severe sepsis and septic shock, yet the methods of diagnosis described in the literature are often inconsistent. The recently published 2016 American Society of Echocardiography and European Association of Cardiovascular Imaging (ASE/EACVI) guidelines offer the opportunity to apply a simple pragmatic diagnostic algorithm for the detection of diastolic dysfunction; however, it has not been tested in this cohort. We sought to assess the applicability in septic patients of recently published 2016 ASE/EACVI guidelines on diastolic dysfunction compared with the 2009 ASE guidelines. Our hypothesis was that there would be poor agreement in classifying patients. Prospective observational study includes patients identified as having severe sepsis and septic shock. Patients underwent transthoracic echocardiography on day 1 and day 3 of their ICU admission. Patients with normal and abnormal (ejection fraction < 52%) systolic function had their diastolic function stratified according to both the 2009 ASE and 2016 ASE/EACVI guidelines. On day 1 echocardiography, of the 62 patients analysed, 37 (60%) had diastolic dysfunction according to the 2016 ASE/EACVI guideline with a further 23% having indeterminate diastolic function, compared to the 2009 ASE guidelines where only 13 (21%) had confirmed diastolic dysfunction with 46 (74%) having indeterminate diastolic dysfunction. On day 3, of the 55 patients studied, 22 patients (40%) were defined as having diastolic dysfunction, with 6 (11%) having indeterminate diastolic dysfunction according to the 2016 ASE/EACVI guidelines, compared to the 2009 guidelines where 11 (20%) were confirmed to have diastolic dysfunction and 41 (75%) had indeterminate diastolic function. Systolic dysfunction was identified in 18 of 62 patients (29%) on day 1 and 18 of 55 (33%) on day 3. These patients were classified as having abnormal diastolic function in 94

Patient- and family-centered care permeates critical care where there are often multiple teams involved in management. A method of facilitating information sharing to support shared decision making is essential in appropriately rendering care.This study sought to determine whether incorporating family members on rounds in the intensive care unit (ICU) improves patient and family knowledge and whether doing so improves team time management and satisfaction with the process. A nonrandomized comparative before-and-after trial of incorporating family members on rounds (July to December 2009 vs January to July 2010) in a single quarternary center's surgical ICU assessed (1) family members' knowledge, (2) nurse's and physician's satisfaction with the intervention, (3) frequency and timing of family meetings, and (4) physician's workflow. Intensive care unit demographics and use were similar between time frames. Presurvey (n = 412 family members; 49 nurses) and postsurvey (n = 427 family members; 47 nurses) were coupled with presurvey (n = 5) and postsurvey (n = 6) physicians' informal feedback. Family knowledge of the clinical course and plans increased from 146 (35.4%) of 412 to 374 (87.6%) of 427 (p < 0.0001). Nurses were nearly uniformly satisfied with planned family interaction on rounds (presurvey: 9/49 [18.4%] vs postsurvey: 46/47 [97.9%]; p < 0.0001). Family meetings per week outside of rounds substantially decreased from a mean of 5.3 ± 2.7 to 0.3 ± 0.9; p < 0.001). Goals of therapy including end-of-life care became an element frequently discussed on rounds with families (presurvey: 9.4% ± 4.7% vs postsurvey: 82.5% ± 14.8%; p < 0.0001). One intensivist was dissatisfied with the process. Incorporating family members on rounds in the ICU improves communication and satisfaction and shifts the team's time away from family communication events outside of rounds, condensing most of those activities within the rounding structure.

Intelligent status monitoring for critically ill patients can help medical stuff quickly discover and assess the changes of disease and then make appropriate treatment strategy. However, general-type monitoring model now widely used is difficult to adapt the changes of intensive care unit (ICU) patients' status due to its fixed pattern, and a more robust, efficient and fast monitoring model should be developed to the individual. A data-driven learning approach combining locally weighted projection regression (LWPR) and principal component analysis (PCA) is firstly proposed and applied to monitor the nonlinear process of patients' health status in ICU. LWPR is used to approximate the complex nonlinear process with local linear models, in which PCA could be further applied to status monitoring, and finally a global weighted statistic will be acquired for detecting the possible abnormalities. Moreover, some improved versions are developed, such as LWPR-MPCA and LWPR-JPCA, which also have superior performance. Eighteen subjects were selected from the Physiobank's Multi-parameter Intelligent Monitoring for Intensive Care II (MIMIC II) database, and two vital signs of each subject were chosen for online monitoring. The proposed method was compared with several existing methods including traditional PCA, Partial least squares (PLS), just in time learning combined with modified PCA (L-PCA), and Kernel PCA (KPCA). The experimental results demonstrated that the mean fault detection rate (FDR) of PCA can be improved by 41.7% after adding LWPR. The mean FDR of LWPR-MPCA was increased by 8.3%, compared with the latest reported method L-PCA. Meanwhile, LWPR spent less training time than others, especially KPCA. LWPR is first introduced into ICU patients monitoring and achieves the best monitoring performance including adaptability to changes in patient status, sensitivity for abnormality detection as well as its fast learning speed and low computational complexity.

A relevant innovation about sedation of long-term Intensive Care Unit (ICU) patients is the 'conscious target': patients should be awake even during the critical phases of illness. Enteral sedative administration is nowadays unusual, even though the gastrointestinal tract works soon after ICU admission. The enteral approach cannot produce deep sedation; however, it is as adequate as the intravenous one, if the target is to keep patients awake and adapted to the environment, and has fewer side effects and lower costs. A randomized, controlled, multicenter, single-blind trial comparing enteral and intravenous sedative treatments has been done in 12 Italian ICUs. The main objective was to achieve and maintain the desired sedation level: observed RASS = target RASS ± 1. Three hundred high-risk patients were planned to be randomly assigned to receive either intravenous propofol/midazolam or enteral melatonin/hydroxyzine/lorazepam. Group assignment occurred through online minimization process, in order to balance variables potentially influencing the outcomes (age, sex, SAPS II, type of admission, kidney failure, chronic obstructive pulmonary disease, sepsis) between groups. Once per shift, the staff recorded neurological monitoring using validated tools. Three flowcharts for pain, sedation, and delirium have been proposed; they have been designed to treat potentially correctable factors first, and, only once excluded, to administer neuroactive drugs. The study lasted from January 24 to December 31, 2012. A total of 348 patients have been randomized, through a centralized website, using a specific software expressly designed for this study. The created network of ICUs included a mix of both university and non-university hospitals, with different experience in managing enteral sedation. A dedicated free-access website was also created, in both Italian and English, for continuous education of ICU staff through CME courses. This 'educational research' project aims both to

Bacterial colonization of the stomach and the respiratory tract was qualitatively and quantitatively analyzed over time in 41 consecutive mechanically ventilated patients in a Swedish intensive care unit (ICU), with special emphasis on elucidation of the role of anaerobic bacteria in the lower respiratory tract. Samples were taken from the oropharynx, gastric juice, subglottic space and trachea within 24 h (median 14 h) of intubation, and then every third day until day 18 and every fifth day until day 33. The patients were often heavily colonized with microorganisms not considered to belong to a healthy normal oropharyngeal and gastric flora on admission to the ICU. A majority harbored enterococci, coagulase-negative staphylococci and Candida spp. in at least one site on day 1. Anaerobic bacteria, mainly peptostreptococci and Prevotella spp., were isolated from subglottic and/or tracheal secretions in 59% of the patients. Different routes of tracheal colonization for different groups of microorganisms were found. Primary or concomitant colonization of the oropharynx with staphylococci, enterococci, enterobacteria and Candida was often seen, while Pseudomonas spp., other non-fermenting Gram-negative rods and several anaerobic species often primarily colonized the trachea, indicating exogenous or direct gastrointestinal routes of colonization. Mechanically ventilated patients were heavily colonized in their lower airways by potential pathogenic microorganisms, including a high load of anaerobic bacteria. Different routes of colonization were shown for different species.

STRUCTURED ABSTRACT PURPOSE Although executive dysfunction and depression are common among ICU survivors, their relationship has not been evaluated in this population. We sought to determine 1) if executive dysfunction is independently associated with severity of depressive symptoms or worse mental health-related quality of life (HRQOL) in ICU survivors, and 2) if age modifies these associations. METHODS In a prospective cohort (n=136), we measured executive dysfunction by the Behavior Rating Inventory of Executive Function-Adult, depression by the Beck Depression Inventory-II, and mental HRQOL by the Short-Form 36 (SF-36). We used multiple linear regression models, adjusting for potential confounders. We included age as an interaction term to test for effect modification. RESULTS Executive dysfunction 3 months post-ICU was independently associated with more depressive symptoms and worse mental HRQOL 12 months post-ICU [25th vs 75th percentile of executive functioning scored 4.3 points worse on the depression scale (95% CI =1.3–7.4, p=0.015) and 5 points worse on the SF-36 (95% CI=1.7–8.3, p=0.006)]. Age did not modify these associations (depression p=0.12; mental HRQOL p=0.80). CONCLUSION Regardless of age, executive dysfunction was independently associated with subsequent worse severity of depressive symptoms and worse mental HRQOL. Executive dysfunction may have a key role in the development of depression. PMID:27652496

Bacteremia is a common serious manifestation of disease in the intensive care unit (ICU), which requires quick and accurate determinations of pathogens to select the appropriate antibiotic treatment. To overcome the shortcomings of traditional bacterial culture (BC), we have adapted next-generation sequencing (NGS) technology to identify pathogens from cell-free plasma DNA. In this study, 78 plasma samples from ICU patients were analyzed by both NGS and BC methods and verified by PCR amplification/Sanger sequencing and ten plasma samples from healthy volunteers were analyzed by NGS as negative controls to define or calibrate the threshold of the NGS methodology. Overall, 1578 suspected patient samples were found to contain bacteria or fungi by NGS, whereas ten patients were diagnosed by BC. Seven samples were diagnosed with bacterial or fungal infection both by NGS and BC. Among them, two samples were diagnosed with two types of bacteria by NGS, whereas one sample was diagnosed with two types of bacteria by BC, which increased the detectability of bacteria or fungi from 11 with BC to 17 with NGS. Most interestingly, 14 specimens were also diagnosed with viral infection by NGS. The overall diagnostic sensitivity was significantly increased from 12.82% (10/78) by BC alone to 30.77% (24/78) by NGS alone for ICU patients, which provides more useful information for establishing patient treatment plans. NGS technology can be applied to detect bacteria in clinical blood samples as an emerging diagnostic tool rich in information to determine the appropriate treatment of septic patients.

Hypoglycemia is a frequent and feared complication of insulin therapy on the intensive care unit (ICU). Sedated patients in particular are at risk for hypoglycemia due to the absence of clinical symptoms. Furthermore, recent studies point to a correlation between the variability of blood glucose and mortality. Therefore, continuous glucose monitoring has the potential to influence outcome due to a better control of blood glucose in critically ill patients. We evaluated the efficacy, accuracy and safety of a new commercially available subcutaneous continuous glucose monitoring system (sCGM; Sentrino®, Medtronic) in a pilot study in critically ill adult patients. sCGM data were recorded for up to 72 h and values were compared with blood glucose values measured by cassette-based blood gas analyzer (BGA). A total of 14 patients (eight male, six female), with a mean age of 62.1 ± 9.8 years, referred to the ICU after major abdominal surgery were studied. The average simplified acute physiology score (SAPS II) was 35 ± 9. Three patients had known type II diabetes. The average runtime of sensors was 44.1 ± 22.1 h. In comparison to BGA, measurement of blood glucose by sCGM revealed an accuracy of 1.5 mg/dl, and a precision of +34.2 mg/dl to -31.2 mg/dl. Linn's concordance correlation coefficient yielded 0.74 with a 95% confidence interval of 0.68-0.78. No hypoglycemic events, defined as a blood glucose level below 70 mg/dl, occurred during treatment. sCGM monitoring via a subcutaneous sensor demonstrated high accuracy and considerable variability compared to blood gas samples, even in critically ill patients.

Prolonged hospitalization due to burn injury results in physical inactivity and muscle weakness. However, how these changes are distributed among body parts is unknown. The aim of this study was to evaluate the degree of body composition changes in different anatomical regions during ICU hospitalization. Retrospective chart review. Children's burn hospital. Twenty-four severely burned children admitted to our institution between 2000 and 2015. All patients underwent a dual-energy x-ray absorptiometry within 2 weeks after injury and 2 weeks before discharge to determine body composition changes. No subject underwent anabolic intervention. We analyzed changes of bone mineral content, bone mineral density, total fat mass, total mass, and total lean mass of the entire body and specifically analyzed the changes between the upper and lower limbs. In the 24 patients, age was 10 ± 5 years, total body surface area burned was 59% ± 17%, time between dual-energy x-ray absorptiometries was 34 ± 21 days, and length of stay was 39 ± 24 days. We found a significant (p < 0.001) average loss of 3% of lean mass in the whole body; this loss was significantly greater (p < 0.001) in the upper extremities (17%) than in the lower extremities (7%). We also observed a remodeling of the fat compartments, with a significant whole-body increase in fat mass (p < 0.001) that was greater in the truncal region (p < 0.0001) and in the lower limbs (p < 0.05). ICU hospitalization is associated with greater lean mass loss in the upper limbs of burned children. Mobilization programs should include early mobilization of upper limbs to restore upper extremity function.

Objective Cigarette smoking and unhealthy alcohol use are common causes of preventable morbidity and mortality that frequently result in admission to an intensive care unit. Understanding how to identify and intervene in these conditions is important because critical illness may provide a “teachable moment.” Furthermore, the Joint Commission recently proposed screening and receipt of an intervention for tobacco use and unhealthy alcohol use as candidate performance measures for all hospitalized patients. Understanding the efficacy of these interventions may help drive evidence-based institution of programs, if deemed appropriate. Data Sources A summary of the published medical literature on interventions for unhealthy alcohol use and smoking obtained through a PubMed search. Summary Interventions focusing on behavioral counseling for cigarette smoking in hospitalized patients have been extensively studied. Several studies include or focus on critically ill patients. The evidence demonstrates that behavioral counseling leads to increased rates of smoking cessation but the effect depends on the intensity of the intervention. The identification of unhealthy alcohol use can lead to brief interventions. These interventions are particularly effective in trauma patients with unhealthy alcohol use. However, the current literature would not support routine delivery of brief interventions for unhealthy alcohol use in the medical ICU population. Conclusion ICU admission represents a “teachable moment” for smokers and some patients with unhealthy alcohol use. Future studies should assess the efficacy of brief interventions for unhealthy alcohol use in medical ICU patients. In addition, identification of the timing and optimal individual to conduct the intervention will be necessary. PMID:21494113

2015-01-01

Transfer of intensive care unit (ICU) patients to the operating room (OR) is a resource-intensive, time-consuming process that often results in patient throughput inefficiencies, deficiencies in information transfer, and suboptimal nurse to patient ratios. This study evaluates the implementation of a coordinated patient transport system (CPTS) designed to address these issues. Using data from 1,557 patient transfers covering the 2006-2010 period, interrupted time series and before and after designs were used to analyze the effect of implementing a CPTS at Mayo Clinic, Rochester. Using a segmented regression for the interrupted time series, on-time OR start time deviations were found to be significantly lower after the implementation of CPTS (p < .0001). The implementation resulted in a fourfold improvement in on-time OR starts (p < .01) while significantly reducing idle OR time (p < .01). A coordinated patient transfer process for moving patient from ICUs to ORs can significantly improve OR efficiency, reduce nonvalue added time, and ensure quality of care by preserving appropriate care provider to patient ratios.

A diagnosis of severe sepsis or septic shock has been shown to significantly increase mortality rate independent of other factors. Research has revealed all cause hospital case fatality rates have declined yet the percentage of severe sepsis cases continues to increase and age-adjusted mortality rates from severe sepsis and septic shock has significantly increased during the same time period. Patients with severe sepsis demonstrate ongoing mortality rate increases for up to 2 years following hospitalization when compared to aged matched controls of nonseptic patients. International guidelines with mortality benefit for the management of severe sepsis and septic shock have been illustrated in the latest surviving sepsis campaign. The objective of this study was to increase the percentage of patients admitted to the hospital with a diagnosis of severe sepsis or septic shock who met guidelines based on surviving sepsis campaign. A retrospective chart review was conducted for patients admitted to UHC from January 2016 to present to identify cases with a diagnosis of severe sepsis or septic shock, and whether they met guidelines set forth by surviving sepsis campaign both before and after an intervention program which included interviews with providers failing to meet protocol, educational sessions on guidelines to meet protocol, resident led quality improvement workshops to address barriers to meeting protocol, and development of an EMR power plan to assist providers on meeting protocol. 139 cases with a diagnosis, or meeting criteria for, severe sepsis or septic shock were identified during the period of 1/1/2016-9/30/2016 with an average of 43 percent of total cases which met guidelines. Trend analysis revealed increased compliance following resident lead intervention program with 31 percent and 49 percent before and after intervention, respectively. ICU data is currently being analyzed for meeting guidelines and have not been included in current data. The most

To evaluate the effectiveness and safety of a family-centered care intervention in a Chinese neonatal ICU. Pilot study using a randomized controlled trial design to inform a main randomized controlled trial study. Stand-alone tertiary children's hospital in China with a 60-bed neonatal ICU serving as a regional neonatal ICU center. Premature infants (n = 61) and their parents (n = 110). Parent education program followed by parents' participation in care as primary caregiver until discharge for a minimum of 4 hours per day. Primary outcomes were infants' weight gain at discharge, length of stay, and readmission. Parental outcomes were stress, anxiety, satisfaction, and clinical knowledge. Infants in family-centered care group (n = 31) had higher weight gain (886g vs 542g; p = 0.013), less neonatal ICU length of stay in days (43 vs 46; p = 0.937), and decreased readmission rate at 1 week (41.9 vs 70.0; p = 0.045) and at 1 month (6.5% vs 50%; p < 0.001) compared with the control group (n = 30). Total Mean Parental Stress and Anxiety scores were lower in the family-centered care group (42 vs 59; p ≤ 0.007), mean satisfaction rates in family-centered care group were higher compared with control group (96 vs 90; p < 0.001), and parents in the family-centered care group had better educational outcomes related to neonatal specialized care skills (p < 0.05). Involving parents in the care of their infant improved clinical outcomes of infants. Family-centered care also contributed to a better understanding of parent's clinical education, decrease stress levels, and increased parental satisfaction. Our study suggests that involving parents in the daily care of their infants is feasible and should be promoted by neonatal ICU clinicians.

The electronic chart review habits of intensive care unit (ICU) clinicians admitting new patients are largely unknown but necessary to inform the design of existing and future critical care information systems. We conducted a survey study to assess the electronic chart review practices, information needs, workflow, and data display preferences among medical ICU clinicians admitting new patients. We surveyed rotating residents, critical care fellows, advanced practice providers, and attending physicians at three Mayo Clinic sites (Minnesota, Florida, and Arizona) via email with a single follow-up reminder message. Of 234 clinicians invited, 156 completed the full survey (67% response rate). Ninety-two percent of medical ICU clinicians performed electronic chart review for the majority of new patients. Clinicians estimated spending a median (interquartile range (IQR)) of 15 (10-20) minutes for a typical case, and 25 (15-40) minutes for complex cases, with no difference across training levels. Chart review spans 3 or more years for two-thirds of clinicians, with the most relevant categories being imaging, laboratory studies, diagnostic studies, microbiology reports, and clinical notes, although most time is spent reviewing notes. Most clinicians (77%) worry about overlooking important information due to the volume of data (74%) and inadequate display/organization (63%). Potential solutions are chronologic ordering of disparate data types, color coding, and explicit data filtering techniques. The ability to dynamically customize information display for different users and varying clinical scenarios is paramount. Electronic chart review of historical data is an important, prevalent, and potentially time-consuming activity among medical ICU clinicians who would benefit from improved information display systems.

Developing clinical practice guidelines: reviewing, reporting, and publishing guidelines; updating guidelines; and the emerging issues of enhancing guideline implementability and accounting for comorbid conditions in guideline development

PubMed Central

2012-01-01

Clinical practice guidelines are one of the foundations of efforts to improve health care. In 1999, we authored a paper about methods to develop guidelines. Since it was published, the methods of guideline development have progressed both in terms of methods and necessary procedures and the context for guideline development has changed with the emergence of guideline clearing houses and large scale guideline production organisations (such as the UK National Institute for Health and Clinical Excellence). It therefore seems timely to, in a series of three articles, update and extend our earlier paper. In this third paper we discuss the issues of: reviewing, reporting, and publishing guidelines; updating guidelines; and the two emerging issues of enhancing guideline implementability and how guideline developers should approach dealing with the issue of patients who will be the subject of guidelines having co-morbid conditions.

Typically general wards and intensive care units (ICU) have very different labor organizations, structures and IT-systems in Germany. There is a need for coordination, because of the different working arrangements. Our team investigated the interface between ICU and general ward and especially the respective information transfer in the University hospital in Erlangen (Bavaria, Germany). The research team used a combination of interviews, observations and the analysis of transfer records and forms as part of a methodical triangulation. We identified 41 topics, which are discussed or presented in writing during the handover. In a second step, we investigate the requirements of data transmission in expert interviews. A data transfer concept from the perspective of the nurses and physicians was developed and we formulated recommendations for improvements of process and communication for this interface. Finally the data transfer concept was evaluated by the respondents.

Despite the evidence that the patient gender is an important component in the intensive care unit (ICU) admission decision, the role of physician gender and the interaction between the two remain unclear. To investigate the association of both the patient and the physician gender with ICU admission rate of critically ill emergency department (ED) medical patients in a hospital with restricted ICU bed capacity operates with 'closed door' policy. A retrospective population-based cohort analysis. We included patients above 18 admitted to an ED resuscitation room (RR) of a tertiary hospital during 2011-12. Data on medical, laboratory and clinical characteristics were obtained. We used an adjusted multivariable logistic regression to analyze the association between both the patient and the physician gender to the ICU admission decision. We included 831 RR admissions, 388 (46.7%) were female patients and 188 (22.6%) were treated by a female physicians. In adjusted multivariable analysis (adjusted for age, diabetes, mode of hospital transportation, first pH and patients who were treated with definitive airway and vasso-pressors in the RR), female-female combination (patient-physician, respectively) showed the lowest likelihood to be admitted to ICU (adjusted OR: 0.21; 95% CI: 0.09-0.51) compared to male-male combination, in addition to a smaller decrease among female-male (adjusted OR: 0.53; 95% CI: 0.32-0.86) and male-female (adjusted OR: 0.43; 95% CI: 0.21-0.89) combinations. We demonstrated the existence of the possible gender bias where female gender of the patient and treating physician diminish the likelihood of the restricted health resource use.

Enhanced mobility in the Intensive Care Unit (ICU) could minimize the negative effects of critical illness, such as declines in cognitive, muscular, respiratory, and functional capacity. We aim to compare the functional status at ICU discharge of patients who underwent a progressive mobilization protocol versus patients who received conventional physiotherapy. We also examine the level of physical activity in the ICU, the degree of pulmonary and muscle function, and the length of stay to analyze correlations between these variables. This is a protocol for a randomized controlled trial with blind evaluation. Ninety-six ICU patients will be recruited from a single center and randomly assigned to a control group or an intervention group. To determine the level of protocol activity the patient will receive, the patients' ability to participate actively and their muscle strength will be considered. The protocol consists of five phases, ranging from passive therapies to walking and climbing stairs. The primary outcome will be the functional status at ICU discharge, measured with the Barthel Index and the ICU Mobility Scale (IMS). Measured secondary outcomes will include the level of physical activity, maximal inspiratory and expiratory pressures, forced expiratory volume in 1 second, maximum voluntary ventilation, handgrip strength, surface electromyography of the lower limb muscles, and results of the Timed Up and Go and 2-Minute Walk tests. Evaluations will be made within 2 days of ICU discharge except for the level of activity, which will be evaluated daily. Physiological variables and activity level will be analyzed by chi-square and t tests, according to the intention-to-treat paradigm. Mobility and exercise in the ICU should be undertaken with intensity, quantity, duration, and frequency adjusted according to the patients' status. The results of this study may contribute to new knowledge of early mobility in the ICU, activity level, and varying benefits in critical

Discrimination between infectious and noninfectious causes of acute respiratory failure is difficult in patients admitted to the ICU after a period of hospitalization. Using a novel biomarker test (SeptiCyte LAB), we aimed to distinguish between infection and inflammation in this population. Nested cohort study. Two tertiary mixed ICUs in the Netherlands. Hospitalized patients with acute respiratory failure requiring mechanical ventilation upon ICU admission from 2011 to 2013. Patients having an established infection diagnosis or an evidently noninfectious reason for intubation were excluded. None. Blood samples were collected upon ICU admission. Test results were categorized into four probability bands (higher bands indicating higher infection probability) and compared with the infection plausibility as rated by post hoc assessment using strict definitions. Of 467 included patients, 373 (80%) were treated for a suspected infection at admission. Infection plausibility was classified as ruled out, undetermined, or confirmed in 135 (29%), 135 (29%), and 197 (42%) patients, respectively. Test results correlated with infection plausibility (Spearman's rho 0.332; p < 0.001). After exclusion of undetermined cases, positive predictive values were 29%, 54%, and 76% for probability bands 2, 3, and 4, respectively, whereas the negative predictive value for band 1 was 76%. Diagnostic discrimination of SeptiCyte LAB and C-reactive protein was similar (p = 0.919). Among hospitalized patients admitted to the ICU with clinical uncertainty regarding the etiology of acute respiratory failure, the diagnostic value of SeptiCyte LAB was limited.

Knowledge and attitude of ICU nurses, students and patients towards the Austrian organ donation law

2013-01-01

Background A survey on the knowledge and attitudes towards the Austrian organ donation legislation (an opt-out solution) of selected groups of the Austrian population taking into account factors such as age, gender, level of education, affiliation to healthcare professions and health related studies was conducted. Methods An online survey among 3 target groups (ICU nurses, health science students and non health science students) was performed and results were compared to the answers from transplantation patients to a paper questionnaire. A total of 8415 persons were asked to participate in the survey and 2025 (24%) persons correctly completed the questionnaire. 1945 online responses (ICU nurses n = 185; students of health sciences n = 1277; students of non-health science related courses n = 483) were analysed and data were compared to 80 manually filled-in responses from patients from a previous study. Results 84% of participants state that they know the Austrian organ donation legislation; this percentage varies significantly (p < 0.05) within the target groups and is influenced by demographic variables of the participants. 74% think that the law is good and 79% do not favour a change. Opinions and attitudes towards the legal situation are positively influenced by the affiliation to healthcare professions and health-related fields of study. Interviewed persons who were aware of the legislation before the survey had a more positive attitude towards the existing legislation (77% versus 74%, p < 0.05). Conclusions The information level on Austrian organ donation legislation is high. ICU nurses and those who did not know the law before were most critical towards the existing legislation. Therefore education to increase knowledge in the general population and goal-oriented efforts to increase awareness in the target groups should be emphasized. PMID:23948068

Family members of critically ill patients who participate in research focused on palliative care issues have been found to be systematically different from those who do not. These differences threaten the validity of research and raise ethical questions about worsening disparities in care by failing to represent diverse perspectives. This study's aims were to explore: 1) barriers and facilitators influencing family members' decisions to participate in palliative care research; and 2) potential methods to enhance research participation. Family members who were asked to participate in a randomized trial testing the efficacy of a facilitator to improve clinician-family communication in the intensive care unit (ICU). Family members who participated (n = 17) and those who declined participation (n = 7) in Family Communication Study were interviewed about their recruitment experiences. We also included family members of currently critically ill patients to assess current experiences (n = 4). Interviews were audio-recorded and transcribed. Investigators used thematic analysis to identify factors influencing family members' decisions. Transcripts were co-reviewed to synthesize codes and themes. Three factors influencing participants' decisions were identified: Altruism, Research Experience, and Enhanced Resources. Altruism and Research Experience described intrinsic characteristics that are less amenable to strategies for improving participation rates. Enhanced Resources reflects families' desires for increased access to information and logistical and emotional support. Family members found their recruitment experiences to be positive when staff were knowledgeable about the ICU, sensitive to the stressful circumstances, and conveyed a caring attitude. By training research staff to be supportive of families' emotional needs and need for logistical knowledge about the ICU, recruitment of a potentially more diverse sample of families may be enhanced.

To evaluate the effectiveness of warning labels permanently attached to mechanical ventilators in improving the practice of hand washing and use of gloves by respiratory care practitioners (RCPs) in the ICU. The study consisted of two 4-week periods. Daily observations of hand washing and use of gloves by RCPs were made over four 1-h observation periods. Prior to the first 4-week period, the importance of hand washing and use of gloves was presented to all staff. At the end of the first period, "Wash Hands Use Gloves" labels were permanently placed on all ventilators in the ICU. The RCPs were not aware they were being observed for hand washing and use of gloves in either period. The total number of encounters between the RCPs and patients as well as the rates of hand washing and use of gloves were obtained during the study. The rates of hand washing and use of gloves were significantly higher during the second period when labels were attached to the ventilators, as compared to the rates during the first period: hand washing, 92% vs 46% (p < 0.05); use of gloves, 92% vs 43% (p < 0.05), respectively. During the first period, the rates of pre-encounter hand washing (78%, 48%, 27%, and 29% in weeks 1 through 4, respectively) and the use of gloves (56%, 37%, 32%, and 45% in weeks 1 through 4, respectively) were primarily declining. This was not observed during the second period of the study (94%, 88%, 95%, and 92% in weeks 1 through 4, respectively) for the rates of pre-encounter hand washing and the use of gloves. Simple measures such as the placement of warning labels on mechanical ventilators can significantly improve hand washing and use of gloves by RCPs in the ICU.

Computerization of guidelines: towards a "guideline markup language".

Medical decision making is one of the most difficult daily tasks for physicians. Guidelines have been designed to reduce variance between physicians in daily practice, to improve patient outcomes and to control costs. In fact, few physicians use guidelines in daily practice. A way to ease the use of guidelines is to implement computerised guidelines (computer reminders). We present in this paper a method of computerising guidelines. Our objectives were: 1) to propose a generic model that can be instantiated for any specific guidelines; 2) to use eXtensible Markup Language (XML) as a guideline representation language to instantiate the generic model for a specific guideline. Our model is an object representation of a clinical algorithm, it has been validated by running two different guidelines issued by a French official Agency. In spite of some limitations, we found that this model is expressive enough to represent complex guidelines devoted to diabetes and hypertension management. We conclude that XML can be used as a description format to structure guidelines and as an interface between paper-based guidelines and computer applications.

The etiology of delirium in intensive care units (ICU) is usually multi-factorial. There is common "myth" that lunar phases affect human body especially human brains (and minds). In the absence of any pre-existing studies in ICU patients, the current retrospective study was planned to investigate whether lunar phases play any role in ICU delirium by assessing if lunar phases correlate with prevalence of ICU delirium as judged by the corresponding consumptions of rescue anti-psychotics used for delirium in ICU. After institutional review board approval with waived consent, the daily census of ICU patients from the administrative records was accessed at an academic university's Non-Cancer Hospital in a Metropolitan City of United States. Thereafter, the ICU pharmacy's electronic database was accessed to obtain data on the use of haloperidol and quetiapine over the two time periods for patients aged 18 years or above. Subsequently the data was analyzed for whether the consumption of haloperidol or quetiapine followed any trends corresponding to the lunar phase cycles. A total of 5382 pharmacy records of haloperidol equivalent administrations were analyzed for this study. The cumulative prevalence of incidents of haloperidol equivalent administrations peaked around the full moon period and troughed around the new moon period. As compared to male patients, female patients followed much more uniform trends of haloperidol equivalent administrations' incidents which peaked around the full moon period and troughed around the new moon period. Further sub-analysis of 70-lunar cycles across the various solar months of the total 68-month study period revealed that haloperidol equivalent administrations' incidents peaked around the full moon periods during the months of November-December and around the new moon periods during the month of July which all are interestingly the major holiday months (a potential confounding factor) in the United States.

From guideline modeling to guideline execution: defining guideline-based decision-support services.

We describe our task-based approach to defining the guideline-based decision-support services that the EON system provides. We categorize uses of guidelines in patient-specific decision support into a set of generic tasks--making of decisions, specification of work to be performed, interpretation of data, setting of goals, and issuance of alert and reminders--that can be solved using various techniques. Our model includes constructs required for representing the knowledge used by these techniques. These constructs form a toolkit from which developers can select modeling solutions for guideline task. Based on the tasks and the guideline model, we define a guideline-execution architecture and a model of interactions between a decision-support server and clients that invoke services provided by the server. These services use generic interfaces derived from guideline tasks and their associated modeling constructs. We describe two implementations of these decision-support services and discuss how this work can be generalized. We argue that a well-defined specification of guideline-based decision-support services will facilitate sharing of tools that implement computable clinical guidelines. PMID:11080007

Electronic health records provide valuable resources for understanding the correlation between various diseases and mortality. The analysis of post-discharge mortality is critical for healthcare professionals to follow up potential causes of death after a patient is discharged from the hospital and give prompt treatment. Moreover, it may reduce the cost derived from readmissions and improve the quality of healthcare. Our work focused on post-discharge ICU mortality prediction. In addition to features derived from physiological measurements, we incorporated ICD-9-CM hierarchy into Bayesian topic model learning and extracted topic features from medical notes. We achieved highest AUCs of 0.835 and 0.829 for 30-day and 6-month post-discharge mortality prediction using baseline and topic proportions derived from Labeled-LDA. Moreover, our work emphasized the interpretability of topic features derived from topic model which may facilitates the understanding and investigation of the complexity between mortality and diseases.

Discrepancy in the supply-demand relationship for critical care services precipitates a strain on ICU capacity. Strain can lead to suboptimal quality of care and burnout among providers and contribute to inefficient health resource utilization. We engaged interprofessional healthcare providers to explore their perceptions of the sources, impact, and strategies to manage capacity strain. Qualitative study using a conventional thematic analysis. Nine ICUs across Alberta, Canada. Nineteen focus groups (n = 122 participants). None. Participants' perspectives on strain on ICU capacity and its perceived impact on providers, families, and patient care were explored. Participants defined "capacity strain" as a discrepancy between the availability of ICU beds, providers, and ICU resources (supply) and the need to admit and provide care for critically ill patients (demand). Four interrelated themes of contributors to strain were characterized (each with subthemes): patient/family related, provider related, resource related, and health system related. Patient/family-related subthemes were "increasing patient complexity/acuity," along with patient-provider communication issues ("paucity of advance care planning and goals-of-care designation," "mismatches between patient/family and provider expectations," and "timeliness of end-of-life care planning"). Provider-related factor subthemes were nursing workforce related ("nurse attrition," "inexperienced workforce," "limited mentoring opportunities," and "high patient-to-nurse ratios") and physician related ("frequent turnover/handover" and "variations in care plan"). Resource-related subthemes were "reduced service capability after hours" and "physical bed shortages." Health system-related subthemes were "variable ICU utilization," "preferential "bed" priority for other services," and "high ward bed occupancy." Participants perceived that strain had negative implications for patients ("reduced quality and safety of care" and

New management models develop; one of them is shared leadership where two nurse managers share tasks and responsibility for a unit. The overall aim of this study was to describe the view of the staff about shared leadership at an ICU in Sweden and to study if there were any differences in perceptions between staff groups. This unit had changed the management organisation from single leadership (one nurse manager) to shared leadership (two nurse managers). Sixty-four (79%) registered nurses and assistant nurses responded to a 72 item questionnaire measuring social and organisational factors at work, especially leadership and shared leadership. The results showed that staff reported positive views in relation to the dimensions 'Organisational culture', 'Social interactions', 'Work satisfaction', 'Leadership', 'Shared leadership' and 'Work motives'. Registered nurses reported more positive views than assistant nurses in relation to the dimensions: 'Organisational culture', 'Social interactions', 'Work satisfaction' and 'Leadership'. Further, females had more positive views than males on the dimension 'Social interactions'. Staff described that shared leadership positively influenced the work in terms of confidence. In conclusion, staff reported positive views of work and the model shared leadership in the investigated ICU. One implication is that nurse managers have to be conscious of different health professionals in the unit and it is important to offer a good working environment for all staff. However, more research is needed within the area of shared leadership. A future research project could be to add a qualitative research question about how work and shared leadership affects different health professionals in the day to day practice both at the managerial as well as the team level to improve health care.

Hinkle, Laura J; Bosslet, Gabriel T; Torke, Alexia M

2015-01-01

Family satisfaction with end-of-life care in the ICU has not previously been systematically reviewed. Our objective was to perform a review, synthesizing published data identifying factors associated with family satisfaction with end-of-life care in critically ill adult populations. The following electronic databases were searched: MEDLINE (Medical Literature Analysis and Retrieval System Online), MEDLINE Updated, EMBASE (Excerpta Medical Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), PsycInfo, and PubMed. Two authors reviewed retrieved titles and abstracts. Studies describing nonadult and non-ICU populations or not addressing end-of-life care, family satisfaction, or factors affecting satisfaction were excluded. The remaining articles underwent full review and data extraction by two authors. Quality was assessed using a checklist based on the recommendations of the Consolidated Standards for Reporting Trials group. The search yielded 1,072 articles, with 23 articles describing 14 studies meeting inclusion criteria. All studies obtained satisfaction data from family members via surveys and structured interviews. Specific communication strategies increasing satisfaction included: expressions of empathy, nonabandonment, and assurances of comfort and provision of written information. Additionally, support for shared decision-making, family presence at time of death, and specific patient-care measures such as extubation before death were associated with increased satisfaction. Good-quality communication, support for shared decision-making, and specific patient-care measures were associated with increased satisfaction with end-of-life care. Assessing the family's desire to participate in shared decision-making may also be an important factor. Few interventions increased satisfaction. Future research is needed to further define optimal communication strategies, understand effective integration of palliative care into the ICU, and define

To perform a systematic review of the literature to determine which questionnaires are currently available to measure family satisfaction with care on the ICU and to provide an overview of their quality by evaluating their psychometric properties. We searched PubMed, Embase, The Cochrane Library, Web of Science, PsycINFO, and CINAHL from inception to October 30, 2013. Experimental and observational research articles reporting on questionnaires on family satisfaction and/or needs in the ICU were included. Two reviewers determined eligibility. Design, application mode, language, and the number of studies of the tools were registered. With this information, the tools were globally categorized according to validity and reliability: level I (well-established quality), II (approaching well-established quality), III (promising quality), or IV (unconfirmed quality). The quality of the highest level (I) tools was assessed by further examination of the psychometric properties and sample size of the studies. The search detected 3,655 references, from which 135 articles were included. We found 27 different tools that assessed overall or circumscribed aspects of family satisfaction with ICU care. Only four questionnaires were categorized as level I: the Critical Care Family Needs Inventory, the Society of Critical Care Medicine Family Needs Assessment, the Critical Care Family Satisfaction Survey, and the Family Satisfaction in the Intensive Care Unit. Studies on these questionnaires were of good sample size (n ≥ 100) and showed adequate data on face/content validity and internal consistency. Studies on the Critical Care Family Needs Inventory, the Family Satisfaction in the Intensive Care Unit also contained sufficient data on inter-rater/test-retest reliability, responsiveness, and feasibility. In general, data on measures of central tendency and sensitivity to change were scarce. Of all the questionnaires found, the Critical Care Family Needs Inventory and the Family

To determine whether there is added benefit in detecting electrographic abnormalities from 16-24 hours of continuous video-EEG in adult medical/surgical ICU patients, compared to a 30-minute EEG. This was a prospectively enroled non-randomized study of 130 consecutive ICU patients for whom EEG was requested. For 117 patients, a 30-minute EEG was requested for altered mental state and/or suspected seizures; 83 patients continued with continuous video-EEG for 16-24 hours and 34 patients had only the 30-minute EEG. For 13 patients with prior seizures, continuous video-EEG was requested and was carried out for 16-24 hours. We gathered EEG data prospectively, and reviewed the medical records retrospectively to assess the impact of continuous video-EEG. A total of 83 continuous video-EEG recordings were performed for 16-24 hours beyond 30 minutes of routine EEG. All were slow, and 34% showed epileptiform findings in the first 30 minutes, including 2% with seizures. Over 16-24 hours, 14% developed new or additional epileptiform abnormalities, including 6% with seizures. In 8%, treatment was changed based on continuous video-EEG. Among the 34 EEGs limited to 30 minutes, almost all were slow and 18% showed epileptiform activity, including 3% with seizures. Among the 13 patients with known seizures, continuous video-EEG was slow in all and 69% had epileptiform abnormalities in the first 30 minutes, including 31% with seizures. An additional 8% developed epileptiform abnormalities over 16-24 hours. In 46%, treatment was changed based on continuous video-EEG. This study indicates that if continuous video-EEG is not available, a 30-minute EEG in the ICU has a substantial diagnostic yield and will lead to the detection of the majority of epileptiform abnormalities. In a small percentage of patients, continuous video-EEG will lead to the detection of additional epileptiform abnormalities. In a sub-population, with a history of seizures prior to the initiation of EEG recording

Non-invasive ventilation (NIV) delivered in an intensive care unit (ICU) has become the cornerstone in the treatment of patients with severe chronic obstructive pulmonary disease (COPD) exacerbations. A trend towards managing these patients in non-ICU setting has emerged in recent years, although out-of-hospital survival by this approach and how to prognosticate it is unknown. We aimed to investigate these issues. We consecutively recruited 100 patients (49 males; median age 82 years) who received NIV treatment for acute respiratory failure due to COPD exacerbation in non-ICU medical wards of our hospital, between November 2008 and July 2012. We assessed survival (both in-hospital and out-of-hospital) of all these patients, and analyzed baseline parameters in a Cox proportional hazards model to develop a prognostic score. The median survival in the study population was 383 days (240-980). Overall survival rates were 71.0, 65.3, and 52.7 % at 1, 3, and 12 months, respectively. Age >85 years, a history of heart disorders and a neutrophil count ≥10 × 10(9) were associated with higher mortality at Cox's analysis (χ (2) = 35.766, p = 0.0001), and were used to build a prognostic score (NC85). The presence of two or more factors determined the deepest drop in survival (when NC85 ≥2, mortality at 1, 3, and 12 was 60.7, 70.4, and 77.2 %, respectively, while when NC85 = 0 were 4.0, 4.0, and 14.0 %). A simple model, based on three variables (age, neutrophil count and history of heart disease), accurately predicts survival of COPD patients receiving NIV in a non-ICU setting.

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

Posthypercapnic alkalosis (PHA) is frequently overlooked as a complication of mechanical ventilation in patients with exacerbation of chronic obstructive pulmonary disease (COPD). The current study was conducted to determine the incidence, risk factors for development and effect on outcome of PHA. Eighty-four patients (62 +/- 11 years, range 42-78 years, M:F 58: 26) with exacerbation of COPD with underlying chronic hypercapnic respiratory failure requiring mechanical ventilation were included in a retrospective fashion. PHA was defined as static or rising serum bicarbonate levels, 72 hours or more after return of PaCO2 to baseline, with concurrent pH > 7.44. Development of PHA was noted in 17 patients (20.2%). Corticosteroid use >or=10 days during the hospital stay was an independent risk factor for development of PHA (Adjusted OR, 95% CI: 9.4, 1.6-55.3; P = 0.013). Development of PHA was associated with an increased incidence of ventilator dependence (64.7% vs. 37.3%, OR, 95% CI: 3.1, 1.1-9.4, P = 0.04) and duration of ICU stay (14.7 +/- 6.7 vs. 9.5 +/- 5.9, P = 0.01) but no increase in hospital mortality (43.3% vs. 41.2%, P = NS). It is concluded that PHA is a common complication in patients with exacerbation of COPD requiring mechanical ventilation and is associated with increased incidence of ventilator dependence and ICU stay.

Objective To assess the correlation of psychosocial resiliency factors (mindfulness and coping) with symptoms of posttraumatic stress (PTS), anxiety, and depression in patients recently admitted to the Neuroscience Intensive Care Unit (Neuro-ICU) and their primary informal caregivers. Design A descriptive, cross-sectional correlational study. Setting Neuro-ICU in a major medical center. Participants 78 dyads of patients (total N= 81) and their primary caregivers (total N= 92) from June to December 2015. Study enrollment occurred within the first 2 weeks of patient admission to the Neuro-ICU. Intervention None Measurements and Main Results Dyads completed self-report measures of mindfulness (CAMS-R), coping (MOCS-A), PTS (PCL-S), anxiety (HADS), and depression (HADS). Rates of clinically significant PTS, anxiety, and depressive symptoms were high and comparable between patient and caregiver samples. Own psychological resilience factors and psychiatric symptoms were strongly correlated for both patients and caregivers. Depressive symptoms were interdependent between patients and their caregivers, and one’s own mindfulness was independently related to one’s partner’s depressive symptoms. Conclusions Rates of clinically significant psychiatric symptoms were high, equally prevalent in patients and caregivers, and interdependent between patients and their caregivers. For both patients and caregivers, psychological resiliency factors were associated with both self and partner psychiatric symptoms. Findings suggest that attending to the psychiatric health of both patients and caregivers in the Neuro-ICU is a priority, and that patients and their caregivers must be considered together in a system to fully address either individual’s psychiatric symptoms.

Clinical practice guidelines for psychiatrists: Indian Psychiatric Society guidelines vs. international guidelines: A critical appraisal.

PubMed

2007-10-01

Various guidelines have been proposed to assist psychiatrists all over the world in making appropriate health-care decisions. Though the fundamental premises of all guidelines are the same, yet they differ in certain important aspects; this hampers the universality of these guidelines. There are many internationally accepted guidelines which are based on robust research; still they do not necessarily address the geographical and cultural differences. This necessitates the formulation of regional guidelines, which usually lack the background of robust regional research. The Indian Psychiatric Society (IPS) guidelines were also formulated to cater to the needs of the Indian population. It is now almost three years old, and it is high time it should be compared to the international guidelines, so as to appraise ourselves of the success or shortcomings of the guidelines. This article critically analyzes the IPS guidelines in comparison with the available international guidelines and schematically brings out the positive points, as well as the shortcomings, with the aim of further improvement in our indigenous guidelines.

A Real Time Interface Between a Computerized Physician Order Entry System and the Computerized ICU Medication Administration Record

PubMed Central

Chen, Jeannie; Shabot, M. Michael; LoBue, Mark

2003-01-01

Prior attempts to interface ICU Clinical Information Systems (CIS) to Pharmacy systems have been less than successful. The major problem is that in ICUs, medications frequently have to be administered and charted in the CIS Medication Administration Record (MAR) before pharmacists can enter them into the Pharmacy system. When the Pharmacy system belatedly sends medication orders to the CIS MAR, this may create duplicate entries for medications that ICU nurses have had to enter manually to chart doses actually given. The authors have implemented a real time interface between a Computerized Physician Order Entry (CPOE) system and a CIS operating in ten ICUs that solves this problem. The interface transfers new medication orders including order details and alerts directly to the CIS Medication Administration Record (MAR), where they are immediately available for nurse charting.

It is important to understand the clinical properties of instruments used to measure patient safety before they are used in the setting of an intensive care unit (ICU). The Safety Climate Survey (SCSu), an instrument endorsed by the Institute for Healthcare Improvement, the Safety Culture Scale (SCSc), and the Safety Climate Mean (SCM), a subset of seven items from the SCSu, were administered in four Canadian university affiliated ICUs. All staff including nurses, allied healthcare professionals, non-clinical staff, intensivists, and managers were invited to participate in the cross sectional survey. The response rate was 74% (313/426). The internal consistency of the SCSu and SCSc was 0.86 and 0.80, respectively, while the SCM performed poorly at 0.51. Because of poor internal consistency, no further analysis of the SCM was therefore performed. Test-retest reliability of the SCSu and SCSc was 0.92. Out of a maximum score of 5, the mean (SD) scores of the SCSu and SCSc were 3.4 (0.6) and 3.4 (0.7), respectively. No differences were noted between the three medical-surgical and one cardiovascular ICU. Managers perceived a significantly more positive safety climate than other staff, as measured by the SCSu and SCSc. These results need to be interpreted cautiously because of the small number of management participants. Of the three instruments, the SCSu and SCSc appear to be measuring one construct and are sufficiently reliable. Future research should examine the properties of patient safety instruments in other ICUs, including responsiveness to change, to ensure that they are valid outcome measures for patient safety initiatives.

The Japanese Society of Respiratory Care Medicine and the Japanese Society of Intensive Care Medicine provide here a clinical practice guideline for the management of adult patients with ARDS in the ICU. The guideline was developed applying the GRADE system for performing robust systematic reviews with plausible recommendations. The guideline consists of 13 clinical questions mainly regarding ventilator settings and drug therapies (the last question includes 11 medications that are not approved for clinical use in Japan). The recommendations for adult patients with ARDS include: we suggest against early tracheostomy (GRADE 2C), we suggest using NPPV for early respiratory management (GRADE 2C), we recommend the use of low tidal volumes at 6-8 mL/kg (GRADE 1B), we suggest setting the plateau pressure at 30cmH 2 0 or less (GRADE2B), we suggest using PEEP within the range of plateau pressures less than or equal to 30cmH 2 O, without compromising hemodynamics (Grade 2B), and using higher PEEP levels in patients with moderate to severe ARDS (Grade 2B), we suggest using protocolized methods for liberation from mechanical ventilation (Grade 2D), we suggest prone positioning especially in patients with moderate to severe respiratory dysfunction (GRADE 2C), we suggest against the use of high frequency oscillation (GRADE 2C), we suggest the use of neuromuscular blocking agents in patients requiring mechanical ventilation under certain circumstances (GRADE 2B), we suggest fluid restriction in the management of ARDS (GRADE 2A), we do not suggest the use of neutrophil elastase inhibitors (GRADE 2D), we suggest the administration of steroids, equivalent to methylprednisolone 1-2mg/kg/ day (GRADE 2A), and we do not recommend other medications for the treatment of adult patients with ARDS (GRADE1B; inhaled/intravenous β2 stimulants, prostaglandin E 1 , activated protein C, ketoconazole, and lisofylline, GRADE 1C; inhaled nitric oxide, GRADE 1D; surfactant, GRADE 2B; granulocyte

To evaluate the acquisition rate, identify risk factors, and estimate the risk for subsequent infection, associated with the colonization of the digestive tract with extended-spectrum beta-lactamase-producing Enterobacteriaceae during ICU-hospitalization. PubMed, EMBASE, and reference lists of all eligible articles. Included studies provided data on ICU-acquired colonization with extended-spectrum beta-lactamase-producing Enterobacteriaceae in previously noncolonized and noninfected patients and used the double disk synergy test for extended-spectrum beta-lactamase-producing Enterobacteriaceae phenotypic confirmation. Studies reporting extended-spectrum beta-lactamase-producing Enterobacteriaceae outbreaks or data on pediatric population were excluded. Two authors independently assessed study eligibility and performed data extraction. Thirteen studies (with 15,045 ICUs-patients) were evaluated using a random-effect model and a meta-regression analysis. The acquisition rate of digestive tract colonization during ICU stay was 7% (95% CI, 5-10) and it varies from 3% (95% CI, 2-4) and 4% (95% CI, 2-6) in the Americas and Europe to 21% (95% CI, 9-35) in the Western Pacific region. Previous hospitalization (risk ratio, 1.57 [95% CI, 1.07-2.31]) or antibiotic use (risk ratio, 1.65 [95% CI, 1.15-2.37]) and exposure to beta-lactams/beta-lactamase inhibitors (risk ratio, 1.78 [95% CI, 1.24-2.56]) and carbapenems (risk ratio, 2.13 [95% CI, 1.49-3.06]) during the ICU stay were independent risk factors for ICU-acquired colonization. Importantly, colonized patients were more likely to develop an extended-spectrum beta-lactamase-producing Enterobacteriaceae infection (risk ratio, 49.62 [95% CI, 20.42-120.58]). The sensitivity and specificity of prior colonization to predict subsequent extended-spectrum beta-lactamase-producing Enterobacteriaceae infection were 95.1% (95% CI, 54.7-99.7) and 89.2% (95% CI, 77.2-95.3), respectively.

The lactate/albumin ratio has been reported to be associated with mortality in pediatric patients with sepsis. We aimed to evaluate the lactate/albumin ratio for its prognostic relevance in a larger collective of critically ill (adult) patients admitted to an intensive care unit (ICU). A total of 348 medical patients admitted to a German ICU for sepsis between 2004 and 2009 were included. Follow-up of patients was performed retrospectively between May 2013 and November 2013. The association of the lactate/albumin ratio (cut-off 0.15) and both in-hospital and post-discharge mortality was investigated. An optimal cut-off was calculated by means of Youden's index. The lactate/albumin ratio was elevated in non-survivors ( p < 0.001). Patients with an increased lactate/albumin ratio were of similar age, but clinically in a poorer condition and had more pronounced laboratory signs of multi-organ failure. An increased lactate/albumin ratio was associated with adverse in-hospital mortality. An optimal cut-off of 0.15 was calculated and was associated with adverse long-term outcome even after correction for APACHE2 and SAPS2. We matched 99 patients with a lactate/albumin ratio >0.15 to case-controls with a lactate/albumin ratio <0.15 corrected for APACHE2 scores: The group with a lactate/albumin ratio >0.15 evidenced adverse in-hospital outcome in a paired analysis with a difference of 27% (95%CI 10-43%; p < 0.01). Regarding long-term mortality, again, patients in the group with a lactate/albumin ratio >0.15 showed adverse outcomes ( p < 0.001). An increased lactate/albumin ratio was significantly associated with an adverse outcome in critically ill patients admitted to an ICU, even after correction for confounders. The lactate/albumin ratio might constitute an independent, readily available, and important parameter for risk stratification in the critically ill.

This study investigated the association between physician education in EOL and variability in EOL practice, as well as the differences between beliefs and practices regarding EOL in the ICU. Physicians from 11 ICUs at a university hospital completed a survey presenting a patient in a vegetative state with no family or advance directives. Questions addressed approaches to EOL care, as well physicians' personal, professional and EOL educational characteristics. The response rate was 89%, with 105 questionnaires analyzed. Mean age was 38 ± 8 years, with a mean of 14 ± 7 years since graduation. Physicians who did not apply do-not-resuscitate (DNR) orders were less likely to have attended EOL classes than those who applied written DNR orders [0/7 vs. 31/47, OR = 0.549 (0.356-0.848), P = 0.001]. Physicians who involved nurses in the decision-making process were more likely to be ICU specialists [17/22 vs. 46/83, OR = 4.1959 (1.271-13.845), P = 0.013] than physicians who made such decisions among themselves or referred to ethical or judicial committees. Physicians who would apply "full code" had less often read about EOL [3/22 vs. 11/20, OR = 0.0939 (0.012-0.710), P = 0.012] and had less interest in discussing EOL [17/22 vs. 20/20, OR = 0.210 (0.122-0.361), P < 0.001], than physicians who would withdraw life-sustaining therapies. Forty-four percent of respondents would not do what they believed was best for their patient, with 98% of them believing a less aggressive attitude preferable. Legal concerns were the leading cause for this dichotomy. Physician education about EOL is associated with variability in EOL decisions in the ICU. Moreover, actual practice may differ from what physicians believe is best for the patient.

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.
