Teaching bedside manner might prove to be one of the most challenging tasks in medical education as it is not easy to structure or formalise such training. Besides, the rigorous training process for acquiring clinical and technical skills often overshadows the humanistic aspect of medical care. The aim of this study was to assess the perception of final year medical students as well as the faculty regarding the teaching and practice of bedside manner including a brief evaluation of students' bedside manner. A cross-sectional study was conducted involving final year medical students from five medical colleges (n = 193) and faculty from a single institution (n=29). Sample was selected using systematic random or convenient sampling techniques. Data was collected using self administered, anonymous, structured questionnaire. Data were analysed using SPSS-17. While evaluating students' bedside manner, 85% of the students reported they always take consent while interacting with a patient whereas, only 17% of the faculty members agreed with this. Only 3% of the faculty members reported that students take care of privacy of patients and none of them thought that students reassure a patient during an encounter whereas the percentages among students were 76% and 48%, respectively. Though students thought they need to improve, majority (56%) of them was confident of their bedside manner. On the other hand, 83% of the faculty members rated students' bedside manner from fair to poor. A large proportion (69%) of the faculty members were not satisfied with the quality of teaching regarding bedside manner, reporting lack of focus on this particular aspect of medical care as the most important cause. Majority of the students (87%) believed doctors have a better bedside manner in private as compared to public hospitals. Students have an inflated evaluation of their bedside manner but majority felt a need to improve. A sharp contrast exists between students' and faculty's opinion regarding the practice of bedside manner by students. An outright lack of focus on bedside manner was reported as the most important cause for inadequate emphasis on teaching this particular aspect of medical care.

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.

To investigate the effect of the bedside lung ultrasound in emergency(BLUE)-plus lung ultrasound protocol on lung consolidation and atelectasis of critical patients. All patients who need to receive mechanical ventilation for more than 48 hours in ICU from June 2010 to December 2011 in Peking Union Medical College Hospital were included in the study. BLUE-plus and BLUE lung ultrasound, bedside X-ray, lung CT examination were performed on all patients at the same time. The condition of lung consolidation and atelectasis discovered by BLUE-plus lung ultrasound protocol was recorded and compared with bedside X-ray or lung CT. The difference in assessment of lung consolidation and atelectasis between BLUE-plus lung ultrasound protocol and BLUE protocol was compared. A total of 78 patients were finally enrolled in the study. The lung CT found 70 cases (89.74%) had different degrees of lung consolidation and atelectasis. The sensitivity, specificity and diagnostic accuracy of lung consolidation and atelectasis by the bedside chest X-ray were 31.29%, 75.00% and 38.46%, respectively. BLUE-plus lung ultrasound protocol found 68 cases with lung consolidation and atelectasis, and its sensitivity, specificity, and diagnostic accuracy were 95.71%, 87.50% and 94.87%, respectively, which were significantly higher than those of lung CT. BLUE protocol found 48 cases of lung consolidation and atelectasis, and its sensitivity, specificity, and diagnostic accuracy were 65.71%, 75.00% and 66.67%, respectively. The position of lung consolidation and atelectasis which hadn't been found by BLUE protocol was mainly proved to be located in the basement of lung by lung CT. The incidence of lung consolidation and atelectasis in critical patients who received mechanical ventilation is high. The BLUE-plus lung ultrasound protocol has a relatively higher sensitivity, specificity and diagnostic accuracy for consolidation and atelectasis, which can find majority of consolidation and atelectasis. As BLUE-plus lung ultrasound is a bedside noninvasive method allowing immediate assessment of most lung consolidation and atelectasis, it will be likely the alternative of the CT and play a key role in assessment of lung consolidation and atelectasis.

Dysphagia is associated with aspiration, pneumonia, and malnutrition, but remains challenging to identify at the bedside. A variety of exam protocols and maneuvers are commonly used, but the efficacy of these maneuvers is highly variable. We conducted a comprehensive search of 7 databases, including MEDLINE, Embase, and Scopus, from each database's earliest inception through June 9, 2014. Studies reporting diagnostic performance of a bedside examination maneuver compared to a reference gold standard (videofluoroscopic swallow study or flexible endoscopic evaluation of swallowing with sensory testing) were included for analysis. From each study, data were abstracted based on the type of diagnostic method and reference standard study population and inclusion/exclusion characteristics, design, and prediction of aspiration. The search strategy identified 38 articles meeting inclusion criteria. Overall, most bedside examinations lacked sufficient sensitivity to be used for screening purposes across all patient populations examined. Individual studies found dysphonia assessments, abnormal pharyngeal sensation assessments, dual axis accelerometry, and 1 description of water swallow testing to be sensitive tools, but none were reported as consistently sensitive. A preponderance of identified studies was in poststroke adults, limiting the generalizability of results. No bedside screening protocol has been shown to provide adequate predictive value for presence of aspiration. Several individual exam maneuvers demonstrated reasonable sensitivity, but reproducibility and consistency of these protocols was not established. More research is needed to design an optimal protocol for dysphagia detection. © 2015 Society of Hospital Medicine.

The purpose of this project was to enhance the knowledge of the bedside nurse in diabetes management. A forum for ongoing support and exploration of clinical problems, along with the distribution of educational tools were the components of this program. Diabetes accounts for 30% of patients admitted to the hospital. It has become more challenging to manage as the treatment choices have increased. There are a number of researchers who have identified nurse and physician knowledge of diabetes management principles as suboptimal. DESCRIPTION OF THE INNOVATION: Staff nurses are educated for a role as a Diabetes Management Mentor and are expected to educate/dialogue with peers monthly, model advocacy and diabetes patient education skills, facilitate referrals for diabetes education, and direct staff to resources for diabetes management. Diabetes Management Mentors feel more confident in their knowledge of diabetes and their ability to resolve clinical issues as they arise. The Diabetes Management Mentor role is another avenue for nurses to refine their clinical knowledge base and acquire skills to share with colleagues while remaining at the bedside. The clinical nurse specialist is expertly prepared to foster the professional development of bedside nurses while simultaneously making a positive impact on disease management. Opportunity for future investigation includes efficacy of teaching tools on diabetes mastery, the effect of clinical nurse specialist mentoring on a select group of bedside nurses, and the Diabetes Management Mentor's impact on prevention of near-miss events.

Bedside teaching is defined as any teaching in the presence of patient and is the core teaching strategy during the clinical years of a medical student. Although it is considered the most effective method to teach clinical and communication skills but its quality is deteriorating with the passage of time. The objective of this study is to explore faculty's perceptions about bedside teaching. This study was conducted in clinical disciplines of Ayub Medical College and hospital Abbottabad, Pakistan from January 2012 to July 2012. Pragmatic paradigm was selected to gather both quantitative and qualitative information. Data was collected sequentially to validate findings. Perceptions of all professors of clinical subjects about bed side teaching were recorded on a close-ended structured questionnaire. Then in-depth interviews were taken from 5 professors using an open ended questionnaire. Quantitative data was analysed using, SPSS-16. Qualitative research data was analysed through content analysis. Out of 20 professors of clinical departments 18 agreed to respond to the questionnaire assessing their perceptions about bed side teaching. Non-existence of bedside teaching curriculum, lack of discipline in students and faculty, lack of accountability, poor job satisfaction and low salary were identified as major factors responsible for decline in quality of bedside teaching. Most of them advocated that curriculum development, planning bedside teaching, implementation of discipline and accountability, improved job satisfaction and performance based promotions will improve quality of clinical teaching. Curriculum development for bedside teaching, institutional discipline, application of best planning strategies, performance based appraisal of faculty and good job satisfaction can make bedside teaching an effective instructional tool.

BACKGROUND Bedside rationing by physicians is controversial. The debate, however, is clouded by lack of information regarding the extent and character of bedside rationing. DESIGN, SETTING, AND PARTICIPANTS We developed a survey instrument to examine the frequency, criteria, and strategies used for bedside rationing. Content validity was assessed through expert assessment and scales were tested for internal consistency. The questionnaire was translated and administered to General Internists in Norway, Switzerland, Italy, and the United Kingdom. Logistic regression was used to identify the variables associated with reported rationing. RESULTS Survey respondents (N =656, response rate 43%) ranged in age from 28 to 82, and averaged 25 years in practice. Most respondents (82.3%) showed some degree of agreement with rationing, and 56.3% reported that they did ration interventions. The most frequently mentioned criteria for rationing were a small expected benefit (82.3%), low chances of success (79.8%), an intervention intended to prolong life when quality of life is low (70.6%), and a patient over 85 years of age (70%). The frequency of rationing by clinicians was positively correlated with perceived scarcity of resources (odds ratio [OR]=1.11, 95% confidence interval [CI] 1.06 to 1.16), perceived pressure to ration (OR=2.14, 95% CI 1.52 to 3.01), and agreement with rationing (OR=1.13, 95% CI 1.05 to 1.23). CONCLUSION Bedside rationing is prevalent in all surveyed European countries and varies with physician attitudes and resource availability. The prevalence of physician bedside rationing, which presents physicians with difficult moral dilemmas, highlights the importance of discussions regarding how to ration care in the most ethically justifiable manner.

Practicing evidence-based medicine is an important aspect of providing good medical care. Accessing external information through literature searches on computer-based systems can effectively achieve integration in clinical care. We conducted a pilot study using smartphones, tablets, and stationary computers as search devices at the bedside. The objective was to determine possible differences between the various devices and assess students' internet use habits. In a randomized controlled pilot study, 120 students were divided in three groups. One control group solved clinical problems on a computer and two intervention groups used mobile devices at the bedside. In a questionnaire, students were asked to report their internet use habits as well as their satisfaction with their respective search tool using a 5-point Likert scale. Of 120 surveys, 94 (78.3%) complete data sets were analyzed. The mobility of the tablet (3.90) and the smartphone (4.39) was seen as a significant advantage over the computer (2.38, p < .001). However, for performing an effective literature search at the bedside, the computer (3.22) was rated superior to both tablet computers (2.13) and smartphones (1.68). No significant differences were detected between tablets and smartphones except satisfaction with screen size (tablet 4.10, smartphone 2.00, p < .001). Using a mobile device at the bedside to perform an extensive search is not suitable for students who prefer using computers. However, mobility is regarded as a substantial advantage, and therefore future applications might facilitate quick and simple searches at the bedside.

In order to improve the developmental proficiency of neonatal intensive care unit nurses, a standardised infant positioning assessment tool and a bedside education programme were introduced to the registered nurses in a 46 bed level III neonatal intensive care unit in the western United States. A developmental positioning team collected pre-intervention positioning scores on 54 preterm infants. This was followed by a survey of the registered nurses beliefs and attitudes, the introduction of the standardised assessment tool and an informal education programme. Post-intervention positioning scores were collected on 55 preterm infants, and analysis of the data indicated there was a statistically significant change in mean positioning scores. Additionally, the registered nurses identified several barriers to the implementation of developmental positioning. This research indicates the use of a standardised infant positioning assessment tool and bedside education may be useful strategies for improving the developmental positioning proficiency of NICU nurses.

Inpatient service handoffs are a vulnerable transition during a patients' hospitalization. We hypothesized that performing the service handoff at the patients' bedside may be one mechanism to more efficiently transfer patient information between physicians, while further integrating the patient into their hospital care. We performed a 6-month prospective study of performing a bedside handoff (BHO) at the service transition on a non-teaching hospitalist service. On a weekly basis, transitioning hospitalists co-rounded at patient's bedsides. Post-handoff surveys assessed for completeness of handoff, communication, missed information, and adverse events. A control group who performed the handoff via email, phone or face-to-face was also surveyed. Chi-square and item-response theory (IRT) analysis assessed for differences between BHO and control groups. Narrative responses were elicited to qualitatively describe the BHO. In total, 21/31 (67%) scheduled BHOs were performed. On average, 4 out of 6 eligible patients experienced a BHO, with a total of 90 patients experiencing a BHO. Of those asked to perform the BHO, 52% stated the service transition took 31-60 min compared to 24% in the control group. Controlling for the nesting of observations within physicians, IRT analysis found that BHO respondents had statistically significant greater odds of: reporting increased patient awareness of the service handoff, more certainty in the plan for each patient, less discovery of missed information, and less time needed to learn about the patient on the first day compared to control methods. Narrative responses described a more patient-centered handoff with improved communication that was time-consuming and often logistically difficult to implement. Despite its time-intensive nature, performing the service handoff at the patient's bedside may lead to a more complete and efficient service transition. Published by Elsevier Inc.

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

In the assessment of a pituitary mass, objective visual field testing represents a valuable means of evaluating mass effect, and thus in deciding whether surgical management is warranted. In this vignette, we describe a 73 year-old lady who presented with a three-week history of frontal headache, and 'blurriness' in the left side of her vision, due to a WHO grade III anaplastic haemangiopericytoma compressing the optic chiasm. We report how timely investigations, including an iPad-based visual field test (Melbourne Rapid Field, (MRF)) conducted at the bedside aided swift and appropriate management of the patient. We envisage such a test having a role in assessing bed-bound patients in hospital where access to formal visual field testing is difficult, or indeed in rapid testing of visual fields at the bedside to screen for post-operative complications, such as haematoma.

Bedside rounds have decreased in frequency on teaching services. Perceived barriers toward bedside rounds are inefficiency and patient and house staff lack of preference for this mode of rounding. To evaluate the impact of a bedside rounding intervention on the frequency of bedside rounding, duration of patient encounters and rounding sessions, and patient and resident attitudes toward bedside rounds. A pre- and postintervention design, with a bedside rounding workshop midway through two consecutive internal medicine rotations, with daily resident interviews, patient surveys, and an end-of-the-year survey given to all Medicine house staff. Medicine house staff and medicine patients. Frequency of bedside rounds, duration of new patient encounters and rounding sessions, and patient and house staff attitudes regarding bedside rounds. Forty-four residents completed the bedside rounding workshop. Comparing the preintervention and postintervention phases, bedside rounds increased from <1% to 41% (p < 0.001). The average duration of walk rounding encounters was 16 min, and average duration of bedside rounding encounters was 15 min (p = 0.42). Duration of rounds was 95 and 98 min, respectively (p = 0.52). Patients receiving bedside rounds preferred bedside rounds (99% vs. 83%, p = 0.03) and perceived more time spent at the bedside by their team (p < 0.001). One hundred twelve house staff (71%) responded, with 73% reporting that bedside rounds are better for patient care. House staff performing bedside rounds were less likely to believe that bedside rounds were more educational (53% vs. 78%, p = 0.01). Bedside rounding increased after an educational intervention, and the time to complete bedside rounding encounters was similar to alternative forms of rounding. Patients preferred bedside rounds and perceived more time spent at the bedside when receiving bedside rounds. Medicine residents performing bedside rounds were less likely to believe bedside rounds were more educational, but all house staff valued the importance of bedside rounding for the delivery of patient care.

The frequency at which housestaff need to assess volume status on medical inpatients is unknown. In this brief report, we invited 39 housestaff, over 13 randomly selected dates, to complete a 25-item survey. Participants (n = 31, 79%) logged a total of 455 hours, reporting 197 pages or telephone requests received regarding medical inpatients. Of these, 41 pages (21%) required a volume status assessment. Participants reported their volume status assessment competency to be moderate (median score = 3, interquartile range = 3 to 4, where 1 = not competent to perform independently and 6 = above average competence). In 9 of the 41 assessments (22%), at least 1 barrier was reported in determining volume status. The most commonly reported barriers were conflicting physical examination findings (n = 8, 20%) and suboptimal patient examination (n = 5, 12%). Over 20% of pages regarding admitted medical patients required volume status assessments by medical housestaff. Despite moderate self-reported competence in the ability to assess volume status, barriers such as conflicting physical examination findings and suboptimal patient examinations were present in up to 20% of assessments. Therefore, we urge educators to consider incorporating bedside ultrasound training for volume status into the internal medicine curriculum. © 2014 Society of Hospital Medicine.

Objectives The aims of this study were to assess clinicians’ views and experiences of providing immediate neonatal care at birth beside the mother, and of using a mobile trolley designed to facilitate this bedside care. Design Qualitative interview study with semistructured interviews. Results The results were analysed using thematic analysis. Setting A large UK maternity unit. Participants Clinicians (n=20) from a range of disciplines who were present when the trolley was used to provide neonatal care at birth at the bedside. Five clinicians provided/observed advanced resuscitation by the bedside. Results Five themes were identified: (1) Parents’ involvement, which included ‘Contact and involvement’, ‘Positive emotions for parents’ and ‘Staff communication’; (2) Reservations about neonatal care at birth beside the mother, which included ‘Impact on clinicians’ and ‘Impact on parents’; (3) Practical challenges in providing neonatal care at the bedside, which included ‘Cord length’ and ‘Caesarean section’; (4) Comparison of the trolley with usual resuscitation equipment and (5) Training and integration of bedside care into clinical routine, which included ‘Teething problems’ and ‘Training’. Conclusions Overall, most clinicians were positive about providing immediate neonatal care at the maternal bedside, particularly in terms of the clinicians’ perceptions of the parents’ experience. Clinicians also perceived that their close proximity to parents improved communication. However, there was some concern about performing more intensive interventions in front of parents. Providing immediate neonatal care and resuscitation at the bedside requires staff training and support. PMID:26423852

Multicentre validation of the bedside paediatric early warning system score: a severity of illness score to detect evolving critical illness in hospitalised children

PubMed Central

2011-01-01

Introduction The timely provision of critical care to hospitalised patients at risk for cardiopulmonary arrest is contingent upon identification and referral by frontline providers. Current approaches require improvement. In a single-centre study, we developed the Bedside Paediatric Early Warning System (Bedside PEWS) score to identify patients at risk. The objective of this study was to validate the Bedside PEWS score in a large patient population at multiple hospitals. Methods We performed an international, multicentre, case-control study of children admitted to hospital inpatient units with no limitations on care. Case patients had experienced a clinical deterioration event involving either an immediate call to a resuscitation team or urgent admission to a paediatric intensive care unit. Control patients had no events. The scores ranged from 0 to 26 and were assessed in the 24 hours prior to the clinical deterioration event. Score performance was assessed using the area under the receiver operating characteristic (AUCROC) curve by comparison with the retrospective rating of nurses and the temporal progression of scores in case patients. Results A total of 2,074 patients were evaluated at 4 participating hospitals. The median (interquartile range) maximum Bedside PEWS scores for the 12 hours ending 1 hour before the clinical deterioration event were 8 (5 to 12) in case patients and 2 (1 to 4) in control patients (P < 0.0001). The AUCROC curve (95% confidence interval) was 0.87 (0.85 to 0.89). In case patients, mean scores were 5.3 at 20 to 24 hours and 8.4 at 0 to 4 hours before the event (P < 0.0001). The AUCROC curve (95% CI) of the retrospective nurse ratings was 0.83 (0.81 to 0.86). This was significantly lower than that of the Bedside PEWS score (P < 0.0001). Conclusions The Bedside PEWS score identified children at risk for cardiopulmonary arrest. Scores were elevated and continued to increase in the 24 hours before the clinical deterioration event. Prospective clinical evaluation is needed to determine whether this score will improve the quality of care and patient outcomes. PMID:21812993

Medical students are often afforded the privilege of counselling patients. In the past resources were limited to pen and paper or anatomic models. The evolution of mobile applications allows for limitless access to resources that facilitate bedside patient education. To evaluate the utility of six applications in patient education and promote awareness of implementing mobile resources in clinical care. Six medical students rotating on various clerkships evaluated a total of six mobile applications. Strengths, limitations, and suggested uses in clinical care were identified. Applications included Meditoons™, VisiblePatient™, DrawMD™, CardioTeach™, Visual Anatomy™, and 360° Patient Education Suite™. Data was generated from narrative responses supplied by each student during their evaluation period. Bedside teaching was enhanced by professional illustrations and animations depicting anatomy and pathophysiology. Impromptu teaching was facilitated, as resources were conveniently available on a student's smartphone or tablet. The ability to annotate and modify images and subsequently email to patients was an extraordinary improvement in provider-patient communication. Universal limitations included small smartphone screens and the novelty of new technology. Mobile applications have the potential to greatly enhance patient education and simultaneously build rapport. Endless opportunities exist for their integration in clinical practice, particularly for new diagnoses, consent for procedures, and at time of discharge. Providers should be encouraged to try new applications and utilize them with patients.

BACKGROUND: Blood transfusion chain can be divided into three phases: preanalytical (patient bedside), analytical (steps done at transfusion services), and postanalytical (bedside). Majority (~70%) of events due to blood transfusion have been attributed to errors in bedside blood administration practices. Survey of bedside transfusion practices (pre-analytical and post analytical phase) was done to assess awareness and compliance to guidelines regarding requisition and administration of blood components. MATERIALS AND METHODS: Interview-based questionnaire of ward staff and observational survey of actual transfusion of blood components in total 26 wards of the institute was carried out during November–December 2013. All the collected data were coded (to maintain confidentiality) and analyzed using SPSS (v 20). For analysis, wards were divided into three categories: medical, surgical, and others (including all intensive care units). RESULTS: A total of 104 (33 resident doctors and 71 nursing) staff members were interviewed and observational survey could be conducted in 25 wards during the study period. In the preanalytical phase, major issues were as follows: lack of awareness for institute guidelines (80.6% not aware), improper sampling practices (67.3%), and prescription related (56.7%). In the postanalytical phase, major issues were found to be lack of consent for blood transfusion (72%), improper warming of blood component (~80%), and problems in storage and discarding of blood units. CONCLUSION: There is need to create awareness about policies and guidelines of bed side transfusion among the ward staff. Regular audits are necessary for compliance to guidelines among clinical staff. PMID:29563672

Focused assessment of the gastric antrum by ultrasound is a feasible tool to evaluate the quality of the stomach content. We aimed to determine the amount of training an anesthesiologist would need to achieve competence in the bedside ultrasound technique for qualitative assessment of gastric content. Six anesthesiologists underwent a teaching intervention followed by a formative assessment; then learning curves were constructed. Participants received didactic teaching (reading material, picture library, and lecture) and an interactive hands-on workshop on live models directed by an expert sonographer. The participants were instructed on how to perform a systematic qualitative assessment to diagnose one of three distinct categories of gastric content (empty, clear fluid, solid) in healthy volunteers. Individual learning curves were constructed using the cumulative sum method, and competence was defined as a 90% success rate in a series of ultrasound examinations. A predictive model was further developed based on the entire cohort performance to determine the number of cases required to achieve a 95% success rate. Each anesthesiologist performed 30 ultrasound examinations (a total of 180 assessments), and three of the six participants achieved competence. The average number of cases required to achieve 90% and 95% success rates was estimated to be 24 and 33, respectively. With appropriate training and supervision, it is estimated that anesthesiologists will achieve a 95% success rate in bedside qualitative ultrasound assessment after performing approximately 33 examinations.

Physical examination skills are crucial for a medical doctor. The physical examination of children differs significantly from that of adults. Students often have only limited contact with pediatric patients to practice these skills. In order to improve the acquisition of pediatric physical examination skills during bedside teaching, we have developed a combined video-based training concept, subsequently evaluating its use and perception. Fifteen videos were compiled, demonstrating defined physical examination sequences in children of different ages. Students were encouraged to use these videos as preparation for bedside teaching during their pediatric clerkship. After bedside teaching, acceptance of this approach was evaluated using a 10-item survey, asking for the frequency of video use and the benefits to learning, self-confidence, and preparation of bedside teaching as well as the concluding OSCE. N=175 out of 299 students returned survey forms (58.5%). Students most frequently used videos, either illustrating complete examination sequences or corresponding focus examinations frequently assessed in the OSCE. Students perceived the videos as a helpful method of conveying the practical process and preparation for bedside teaching as well as the OSCE, and altogether considered them a worthwhile learning experience. Self-confidence at bedside teaching was enhanced by preparation with the videos. The demonstration of a defined standardized procedural sequence, explanatory comments, and demonstration of infrequent procedures and findings were perceived as particularly supportive. Long video segments, poor alignment with other curricular learning activities, and technical problems were perceived as less helpful. Students prefer an optional individual use of the videos, with easy technical access, thoughtful combination with the bedside teaching, and consecutive standardized practice of demonstrated procedures. Preparation with instructional videos combined with bedside teaching, were perceived to improve the acquisition of pediatric physical examination skills. Copyright © 2016 Elsevier GmbH.

Mohs micrographic surgery can be employed in recurrent basal cell carcinoma, although it is a time-consuming technique. Recently, ex vivo fluorescence confocal microscopy (FCM) has been employed to obtain a fast assessment of tumor margins at the bedside. In our case we successfully employed ex vivo FCM to assess the tumor margins and we treated the persistent tumor with intensity-modulated radiation therapy. Our case demonstrates that a multidisciplinary approach is very efficient in managing complex and recurrent tumors and highlights the benefits of FCM as a new technique that can be used in the surgical theater to speed up the entire procedure.

Purpose Bedside teaching holds a strong tradition as a key-learning platform for clinical examination in the basic medical clerkship. There is a growing body of literature expressing concern for its witnessed decline in medical school curricula. However, the views of students toward this patient-centered cornerstone in surgical education remain under-reported. The purpose of this study was to gain a nationwide perspective on bedside teaching according to medical students in the United Kingdom. Materials and methods An adapted Delphi method was employed to formulate the question series as part of a multi-step process including a pilot study, which was used to construct this survey. The target population was medical undergraduates in the United Kingdom and participants were recruited via social media. Outcomes assessed included exposure to bedside teaching, perceived benefits of clinical simulation, and junior doctors as clinical teachers. Barriers to clinical examination were also evaluated. Results Overall, 368 completed surveys were received (completion rate 98.9%). Final year students were significantly more likely to report receiving insufficient bedside teaching (P<0.01). Seventy-eight percent of the study group agreed that clinical simulation is a good learning tool for clinical examination. Seventy percent of students felt junior doctors were as able as senior doctors to teach. Lack of confidence was identified as the commonest barrier to overcome when examining patients and two-thirds of students felt they burdened patients during bedside teaching. Conclusion This prospective study confirms the exposure deficit, which medical students experience in bedside teaching. The junior doctor represents a dynamic clinical teacher in the face of working time directives. Peer learning is a novel solution to such pressures. Work is needed to re-establish the hospital wards as a supportive environment for student learning. PMID:26082672

Dynamic airway pressure-time curve profile (Stress Index): a systematic review.

Terragni, Pierpaolo; Bussone, Guido; Mascia, Luciana

2016-01-01

The assessment of respiratory mechanics at the bedside is necessary in order to identify the most protective ventilatory strategy. Indeed in the last 20 years, adverse effects of positive ventilation to the lung structures have led to a reappraisal of the objectives of mechanical ventilation. The ventilator setting requires repeated readjustment over the period of mechanical ventilation dependency and careful respiratory monitoring to minimize the risks, preventing further injury and permitting the lung and airways healing. Among the different methods that have been proposed and validated, the analysis of dynamic P-t curve (named Stress Index, SI) represents an adequate tool available at the bedside, repeatable and, therefore, able to identify the amount of overdistension occurring in the daily clinical practice, when modifying positive end-expiratory pressure. In this review we will analyze the evidence that supports respiratory mechanics assessment at the bedside and the application of the dynamic P/t curve profile (SI) to optimize protective ventilation in patients with acute respiratory failure.

Academic physicians encounter many demands on their time including patient care, quality and performance requirements, research, and education. In an era when patient volume is prioritized and competition for research funding is intense, there is a risk that medical education will become marginalized. Bedside teaching, a responsibility of academic physicians regardless of professional track, is challenged in particular out of concern that it generates inefficiency, and distractions from direct patient care, and can distort physician-patient relationships. At the same time, the bedside is a powerful location for teaching as learners more easily engage with educational content when they can directly see its practical relevance for patient care. Also, bedside teaching enables patients and family members to engage directly in the educational process. Successful bedside teaching can be aided by consideration of four factors: climate, attention, reasoning, and evaluation. Creating a safe environment for learning and patient care is essential. We recommend that educators set expectations about use of medical jargon and engagement of the patient and family before they enter the patient room with trainees. Keep learners focused by asking relevant questions of all members of the team and by maintaining a collective leadership style. Assess and model clinical reasoning through a hypothesis-driven approach that explores the rationale for clinical decisions. Focused, specific, real-time feedback is essential for the learner to modify behaviors for future patient encounters. Together, these strategies may alleviate challenges associated with bedside teaching and ensure it remains a part of physician practice in academic medicine.

Using a Bedside Video-assisted Test Tube Test to Assess Stoma Viability: A Report of 4 Cases.

PubMed

Ahmad, Sarwat; Turner, Keli; Shah, Paulesh; Diaz, Jose

Mucosal discoloration of an intestinal stoma may indicate self-limited venous congestion or necrosis necessitating operative revision. A common bedside technique to assess stoma viability is the "test tube test". A clear tube is inserted into the stoma and a hand-held light is used to assess the color of the stoma. A technique (video-assisted test tube test [VATTT]) developed by the authors utilizes a standard video bronchoscope inserted into a clear plastic blood collection tube to visually inspect and assess the mucosa. This technique was evaluated in 4 patients (age range 49-72 years, all critically ill) with a discolored stoma after emergency surgery. In each case, physical exam revealed ischemic mucosa at the surface either immediately after surgery or after worsening hypotension weeks later. Serial test tube test assessments were ambiguous when trying to assess deeper mucosa. The VATTT assessment showed viable pink mucosa beneath the surface and until the fascia was revealed in 3 patients. One (1) patient had mucosal ischemia down to the fascia, which prompted operative revision of the stoma. The new stoma was assessed with a VATTT and was viable for the entire length of the stoma. VATTT provided an enhanced, magnified, and clearer way to visually assess stoma viability in the postoperative period that can be performed at the bedside with no adverse events. It may prevent unnecessary relaparotomy or enable earlier diagnosis of deep ostomy necrosis. Validity and reliability studies are warranted.

Portable bedside ultrasound: the visual stethoscope of the 21st century

Over the past decade technological advances in the realm of ultrasound have allowed what was once a cumbersome and large machine to become essentially hand-held. This coupled with a greater understanding of lung sonography has revolutionized our bedside assessment of patients. Using ultrasound not as a diagnostic test, but instead as a component of the physical exam, may allow it to become the stethoscope of the 21st century. PMID:22400903

A growing body of evidence supports the use of bedside ultrasound for core Internal Medicine procedures and increasingly as augmentation of the physical exam. The literature also supports that trainees, both medical students and residents, can acquire these skills. However, there is no consensus on training approach. To implement and study the effectiveness of a high-yield and expedited curriculum to train internal medicine interns to use bedside ultrasound for physical examination and procedures. The study was conducted at a metropolitan, academic medical center and included 33 Internal Medicine interns. This was a prospective cohort study of a new educational intervention consisting of a single-day intensive bedside ultrasound workshop followed by two optional hour-long workshops later in the year. The investigation was conducted at Oregon Health & Science University in Portland, Oregon. The intensive day consisted of alternating didactic sessions with small group hands-on ultrasound practice sessions and ultrasound simulations. A 30-question assessment was used to assess ultrasound interpretation knowledge prior to, immediately post, and 6 months post intervention. Thirty-three interns served as their own historical controls. Assessment performance significantly increased after the intervention from a mean pre-test score of 18.3 (60.9 % correct) to a mean post-test score 25.5 (85.0 % correct), P value of <0.0001. This performance remained significantly better at 6 months with a mean score of 23.8 (79.3 % correct), P value <0.0001. There was significant knowledge attrition compared to the immediate post-assessment, P value 0.0099. A single-day ultrasound training session followed by two optional noon conference sessions yielded significantly improved ultrasound interpretation skills in internal medicine interns.

Vibration response imaging (VRI) is a bedside technology to monitor ventilation by detecting lung sound vibrations. It is currently unknown whether VRI is able to accurately monitor the local distribution of ventilation within the lungs. We therefore compared VRI to electrical impedance tomography (EIT), an established technique used for the assessment of regional ventilation. Simultaneous EIT and VRI measurements were performed in the healthy and injured lungs (ALI; induced by saline lavage) at different PEEP levels (0, 5, 10, 15 mbar) in nine piglets. Vibration energy amplitude (VEA) by VRI, and amplitudes of relative impedance changes (rel.ΔZ) by EIT, were evaluated in seven regions of interest (ROIs). To assess the distribution of tidal volume (VT) by VRI and EIT, absolute values were normalized to the VT obtained by simultaneous spirometry measurements. Redistribution of ventilation by ALI and PEEP was detected by VRI and EIT. The linear correlation between pooled VT by VEA and rel.ΔZ was R(2) = 0.96. Bland-Altman analysis showed a bias of -1.07±24.71 ml and limits of agreement of -49.05 to +47.36 ml. Within the different ROIs, correlations of VT-distribution by EIT and VRI ranged between R(2) values of 0.29 and 0.96. ALI and PEEP did not alter the agreement of VT between VRI and EIT. Measurements of regional ventilation distribution by VRI are comparable to those obtained by EIT.

Long bone fractures are currently diagnosed using radiography, but radiography has some disadvantages (radiation and being time consuming). The present study compared the diagnostic accuracy of bedside ultrasound and radiography in multiple trauma patients at the emergency department (ED). The study assessed 80 injured patients with multiple trauma from February 2011 to July 2012. The patients were older than 18 years and triaged to the cardiopulmonary resuscitation ward of the ED. Bedside ultrasound and radiography were conducted for them. The findings were separately and blindly assessed by 2 radiologists. Sensitivity, specificity, the positive and negative predictive value, and κ coefficient were measured to assess the accuracy and validity of ultrasound as compared with radiography. The sensitivity of ultrasound for diagnosis of limb bone fractures was not high enough and ranged between 55% and 75% depending on the fracture site. The specificity of this diagnostic method had an acceptable range of 62% to 84%. Ultrasound negative prediction value was higher than other indices under study and ranged between 73% and 83%, but its positive prediction value varied between 33.3% and 71%. The κ coefficient for diagnosis of long bone fractures of upper limb (κ = 0.58) and upper limb joints (κ = 0.47) and long bones of lower limb (κ = 0.52) was within the medium range. However, the value for diagnosing fractures of lower limb joints (κ = 0.47) was relatively low. Bedside ultrasound is not a reliable method for diagnosing fractures of upper and lower limb bones compared with radiography. © 2013 Elsevier Inc. All rights reserved.

Hospital acquired pressure ulcers (HAPU) are serious, debilitating, and preventable complications in all inpatient populations. Despite evidence of the development of pressure ulcers in the pediatric population, minimal research has been done. Based on observations gathered during quarterly HAPU audits, bedside nursing staff recognized trends in pressure ulcer locations that were not captured using current pressure ulcer risk assessment tools. Together, bedside nurses and nursing leadership created and conducted multiple research studies to investigate the validity and reliability of the Pediatric Pressure Ulcer Prediction and Evaluation Tool (PPUPET).

Simultaneous measurement of instantaneous heart rate and chest wall plethysmography in short-term, metronome guided heart rate variability studies: suitability for assessment of autonomic dysfunction.

PubMed

Perring, S; Jones, E

2003-08-01

Instantaneous heart rate and chest wall motion were measured using a 3-lead ECG and an air pressure chest wall plethysmography system. Chest wall plethysmography traces were found to accurately represent the breathing pattern as measured by spirometry (average correlation coefficient 0.944); though no attempt was made to calibrate plethysmography voltage output to tidal volume. Simultaneous measurements of heart rate and chest wall motion were made for short periods under metronome guided breathing at 6 breaths per minute. The average peak to trough heart rate change per breath cycle (AVEMAX) and maximum correlation between heart rate and breathing cycle (HRBRCORR) were measured. Studies of 44 normal volunteers indicated clear inverse correlation of heart rate variability parameters with age (AVEMAX R = -0.502, P < 0.001) but no significant change in HRBRCORR with age (R = -0.115). Comparison of normal volunteers with diabetics with no history of symptoms associated with autonomic failure indicated significant lower heart rate variability in diabetics (P = 0.005 for AVEMAX) and significantly worse correlation between heart rate and breathing (P < 0.001 for HRBRCORR). Simultaneous measurement of heart rate and breathing offers the possibility of more sensitive diagnosis of autonomic failure in a simple bedside test and gives further insight into the nature of cardio-ventilatory coupling.

The skill of physicians teaching the physical examination skill has decreased, with newer faculty underperforming compared to their seniors. Improved methods of instruction with an emphasis on physical examinations are necessary to both improve the quality of medical education and alleviate the teaching burden of faculty physicians. We developed a curriculum that combines web-based instruction with real-life practice and features individualized feedback. This innovative medical education model should allow the physical examination to be taught and assessed in an effective manner. The model is under study at Baton Rouge General Medical Center. Our goals are to limit faculty burden, maximize student involvement as learners and evaluators, and effectively develop students' critical skills in performing bedside assessments.

Falls in hospitals are common, resulting in injury and anxiety to patients, and large costs to NHS organisations. More than half of all in-patient falls in elderly people in acute care settings occur at the bedside, during transfers or whilst getting up to go to the toilet. In the majority of cases these falls are unwitnessed. There is insufficient evidence underpinning the effectiveness of interventions to guide clinical staff regarding the reduction of falls in the elderly inpatient. New patient monitoring technologies have the potential to offer advances in falls prevention. Bedside sensor equipment can alert staff, not in the immediate vicinity, to a potential problem and avert a fall. However no studies utilizing this assistive technology have demonstrated a significant reduction in falls rates in a randomised controlled trial setting. The research design is an individual patient randomised controlled trial of bedside chair and bed pressure sensors, incorporating a radio-paging alerting mode to alert staff to patients rising from their bed or chair, across five acute elderly care wards in Nottingham University Hospitals NHS Trust. Participants will be randomised to bedside chair and bed sensors or to usual care (without the use of sensors). The primary outcome is the number of bedside in-patient falls. The REFINE study is the first randomised controlled trial of bedside pressure sensors in elderly inpatients in an acute NHS Trust. We will assess whether falls can be successfully and cost effectively reduced using this technology, and report on its acceptability to both patients and staff.

Control of Breathing During Mechanical Ventilation: Who Is the Boss?

2011-01-01

Over the past decade, concepts of control of breathing have increasingly moved from being theoretical concepts to “real world” applied science. The purpose of this review is to examine the basics of control of breathing, discuss the bidirectional relationship between control of breathing and mechanical ventilation, and critically assess the application of this knowledge at the patient’s bedside. The principles of control of breathing remain under-represented in the training curriculum of respiratory therapists and pulmonologists, whereas the day-to-day bedside application of the principles of control of breathing continues to suffer from a lack of outcomes-based research in the intensive care unit. In contrast, the bedside application of the principles of control of breathing to ambulatory subjects with sleep-disordered breathing has out-stripped that in critically ill patients. The evolution of newer technologies, faster real-time computing abilities, and miniaturization of ventilator technology can bring the concepts of control of breathing to the bedside and benefit the critically ill patient. However, market forces, lack of scientific data, lack of research funding, and regulatory obstacles need to be surmounted. PMID:21333174

Pain is common during cancer treatment, and patient self-reporting of pain is an essential first step for ideal cancer pain management. However, many studies on cancer pain management report that, because pain may be underestimated, it is often inadequately managed. The aim of this study was to evaluate the effectiveness of bedside self-assessment of pain intensity for inpatients using a self-reporting pain board. Fifty consecutive inpatients admitted to the Oncology Department of Chungbuk National University Hospital were included in this observational prospective study from February 2011 to December 2011. The medical staff performed pain assessments by asking patients questions and using verbal rated scales (VRS) over 3 consecutive days. Then, for 3 additional days, patients used a self-reporting pain board attached to the bed, which had movable indicators representing 0-10 on a numeric rating scale (NRS) and the frequency of breakthrough pain. Patient reliability over the medical staff's pain assessment increased from 74% to 96% after applying the self-reporting pain board (p=0.004). The gap (mean±standard deviation [SD]) between the NRS reported by patients and the NRS recorded on the medical records decreased from 3.16±2.08 to 1.00±1.02 (p<0.001), and the level of patient satisfaction with pain management increased from 54% to 82% (p=0.002). This study suggests that the self-reporting bedside pain assessment tool provides a reliable and effective means of assessing pain in oncology inpatients.

Bedside teaching with evidence-based practice elements, supported by e-learning activities, can play an important role in modern medical education. Teachers have to incorporate evidence from the medical literature to increase student motivation and interactivity. An integral part of the medical curricula at Palacky University Olomouc (Czech Republic) are real paediatric scenarios supplemented with a review of current literature to enhance evidence-based bedside teaching & learning. Searching for evidence is taught through librarian-guided interactive hands-on sessions and/or web-based tutorials followed by clinical case presentations and feedback. Innovated EBM paediatric clerkship demonstrated students' preferences towards web-based interactive bedside teaching & learning. In two academic years (2007/2008, 2008/2009), learning-focused feedback from 106 and 131 students, resp. was obtained about their attitudes towards evidence-based bedside teaching. The assessment included among others the overall level of instruction, quality of practical evidence-based training, teacher willingness and impact of instruction on increased interest in the specialty. There was some criticism about excessive workload. A parallel survey was carried out on the perceived values of different forms of information skills training (i.e. demonstration, online tutorials, and librarian-guided interactive search sessions) and post-training self-reported level of search skills. The new teaching/learning paediatric portfolio is a challenge for further activities, including effective knowledge translation, continuing medical & professional development of teachers, and didactic, clinically integrated teaching approaches.

Background Attending rounds have transitioned away from the patient's bedside toward the hallway and conference rooms. This transition has brought into question how to best teach on medicine services. Purpose The purpose is to describe learner experiences and attitudes regarding bedside attending rounds at an academic medical institution. Method: Cross-sectional Web-based survey of 102 medical students and 51 internal medicine residents (75% response rate). Results The mean time spent at the bedside during attending rounds was 27.7% (SD = 20.1%). During 73% of the rotations, case presentations occurred at the bedside 25% of the time or less. Learners experiencing bedside case presentations were more likely to prefer bedside case presentations. Despite their stated concerns, learners believe bedside rounds are important for learning core clinical skills. Conclusions Timespentatthe bedside is waning despite learners’ beliefs that bedside learning is important for professional development. Our findings suggest the necessity to re-examine our current teaching methods on internal medicine services. PMID:19330687

Although common, the impact of low-cost bedside visual tools, such as whiteboards, on patient care is unclear. To systematically review the literature and assess the influence of bedside visual tools on patient satisfaction. Medline, Embase, SCOPUS, Web of Science, CINAHL, and CENTRAL. Studies of adult or pediatric hospitalized patients reporting physician identification, understanding of provider roles, patient-provider communication, and satisfaction with care from the use of visual tools were included. Outcomes were categorized as positive, negative, or neutral based on survey responses for identification, communication, and satisfaction. Two reviewers screened studies, extracted data, and assessed the risk of study bias. Sixteen studies met the inclusion criteria. Visual tools included whiteboards (n = 4), physician pictures (n = 7), whiteboard and picture (n = 1), electronic medical record-based patient portals (n = 3), and formatted notepads (n = 1). Tools improved patients' identification of providers (13/13 studies). The impact on understanding the providers' roles was largely positive (8/10 studies). Visual tools improved patient-provider communication (4/5 studies) and satisfaction (6/8 studies). In adults, satisfaction varied between positive with the use of whiteboards (2/5 studies) and neutral with pictures (1/5 studies). Satisfaction related to pictures in pediatric patients was either positive (1/3 studies) or neutral (1/3 studies). Differences in tool format (individual pictures vs handouts with pictures of all providers) and study design (randomized vs cohort) may explain variable outcomes. The use of bedside visual tools appears to improve patient recognition of providers and patient-provider communication. Future studies that include better design and outcome assessment are necessary before widespread use can be recommended. © 2017 Society of Hospital Medicine

Background: Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) with bedside cytopathology is the gold standard for assessment of pancreatic, subepithelial, and other lesions in close proximity to the gastrointestinal tract, but it is time-consuming, has certain diagnostic limitations, and bedside cytopathology is not widely available. Aims: The goal of this study is to compare the diagnostic yield of EUS-guided FNA with on-site cytopathology and EUS-guided core biopsy. Methods: Twenty-six patients with gastrointestinal mass lesions requiring biopsy at a tertiary medical center were included in this retrospective analysis of a prospective cohort. Two core biopsies were taken using a 22 gauge needle followed by FNA guided by a bedside cytopathologist at the same endoscopic session. The diagnostic yield and test characteristics of EUS core biopsy and EUS FNA with bedside cytopathology were examined. Results: The mean number of passes was 3.2 for FNA, and the mean procedure time was 39.4 minutes. The final diagnosis was malignant in 92.3 %. Sensitivity and specificity were 83 % and 100 %, respectively, for FNA, and 91.7 % and 100 %, respectively, for core biopsy. Diagnostic accuracy was 92.3 % for FNA and 84.6 % for core biopsy. The two approaches were in agreement in 88.4 % with a kappa statistic of 0.66 (95 % confidence interval 0.33 – 0.99). Conclusions: An approach using two passes with a core biopsy needle is comparable to the current gold standard of FNA with bedside cytopathology. The performance of two core biopsies is time-efficient and could represent a good alternative to FNA with bedside cytopathology. PMID:26135096

Unlike direct contact with patients' body, hand hygiene practice is often neglected by healthcare workers (HCWs) and visitors after contact with patients' environment. Contact with hospital environmental items may increase risk of pathogen transmission. To enumerate the number of hand-touch contacts by patients, HCWs and visitors with any hospital environmental items. All contact-episodes between person and item were recorded by direct observation in a six-bed cubicle of acute wards for 33 working days. High-touch and mutual-touch items with high contact frequencies by HCWs, patients, and visitors were analysed. In total, 1107 person-episodes with 6144 contact-episodes were observed in 66 observation hours (average: 16.8 person-episodes and 93.1 contact-episodes per hour). Eight of the top 10 high-touch items, including bedside rails, bedside tables, patients' bodies, patients' files, linen, bed curtains, bed frames, and lockers were mutually touched by HCWs, patients, and visitors. Bedside rails topped the list with 13.6 contact-episodes per hour (mean), followed by bedside tables (12.3 contact-episodes per hour). Using patients' body contacts as a reference, it was found that medical staff and nursing staff contacted bedside tables [rate ratio (RR): 1.741, 1.427, respectively] and patients' files (RR: 1.358, 1.324, respectively) more than patients' bodies, and nursing staff also contacted bedside rails (RR: 1.490) more than patients' bodies. Patients' surroundings may be links in the transmission of nosocomial infections because many are frequently touched and mutually contacted by HCWs, patients, and visitors. Therefore, the focus of hand hygiene education, environmental disinfection, and other system changes should be enhanced with respect to high-touch and mutual-touch items.

Clinical teaching has moved from the bedside to conference rooms; many reasons are described for this shift. Yet, essential clinical skills, professionalism, and humanistic patient interactions are best taught at the bedside. Clinical teaching has moved from the bedside to conference rooms; many reasons are described for this decline. This study explored perceptions of teachers and learners on the value of bedside teaching and the humanistic dimensions of bedside interactions that make it imperative to shift clinical teaching back to the bedside. Focus group methodology was used to explore teacher and learner opinions. Four teacher groups consisted of (a) Chief Residents, (b) Residency Program Directors, (c) skilled bedside teachers, and (d) a convenience group of other Department of Medicine faculty at Boston University School of Medicine. Six learner groups consisted 2 each of 3rd-year students, PGY1 medicine residents, and PGY2 medicine residents. Each discussion lasted 60 to 90 minutes. Sessions were audiotaped, transcribed, and analyzed using qualitative methods. Teachers and learners shared several opinions on bedside teaching, particularly around humanistic aspects of bedside interactions. The key themes that emerged included (a) patient involvement in discussions, (b) teachers as role models of humanism, (c) preserving learner autonomy, (d) direct observation and feedback of learners at the bedside, (e) interactions with challenging patients, and (e) admitting limitations. Within these themes, participants noted some behaviors best avoided at the bedside. Teachers and learners regard the bedside as a valuable venue in which to learn core values of medicine. They proposed many strategies to preserve these humanistic values and improve bedside teaching. These strategies are essential for true patient-centered care.

Screening assessments for dysphagia are essential in neurodegenerative disease. Yet there are no purpose-built tools to quantify swallowing deficits at bedside or in clinical trials. A quantifiable, brief, easy to administer assessment that measures the impact of dysphagia and predicts the presence or absence of aspiration is needed. The Clinical Assessment of Dysphagia in Neurodegeneration (CADN) was designed by a multidisciplinary team (neurology, neuropsychology, speech pathology) validated against strict methodological criteria in two neurodegenerative diseases, Parkinson's disease (PD) and degenerative ataxia (DA). CADN comprises two parts, an anamnesis (part one) and consumption (part two). Two-thirds of patients were assessed using reference tests, the SWAL-QOL symptoms subscale (part one) and videofluoroscopic assessment of swallowing (part two). CADN has 11 items and can be administered and scored in an average of 7 min. Test-retest reliability was established using correlation and Bland-Altman plots. 125 patients with a neurodegenerative disease were recruited; 60 PD and 65 DA. Validity was established using ROC graphs and correlations. CADN has sensitivity of 79 and 84% and specificity 71 and 69% for parts one and two, respectively. Significant correlations with disease severity were also observed (p < 0.001) for PD with small to large associations between disease severity and CADN scores for DA. Cutoff scores were identified that signal the presence of clinically meaningful dysphagia symptomatology and risk of aspiration. The CADN is a reliable, valid, brief, quantifiable, and easily deployed assessment of swallowing in neurodegenerative disease. It is thus ideally suited for both clinical bedside assessment and future multicentre clinical trials in neurodegenerative disease.

Background Vibration response imaging (VRI) is a bedside technology to monitor ventilation by detecting lung sound vibrations. It is currently unknown whether VRI is able to accurately monitor the local distribution of ventilation within the lungs. We therefore compared VRI to electrical impedance tomography (EIT), an established technique used for the assessment of regional ventilation. Methodology/Principal Findings Simultaneous EIT and VRI measurements were performed in the healthy and injured lungs (ALI; induced by saline lavage) at different PEEP levels (0, 5, 10, 15 mbar) in nine piglets. Vibration energy amplitude (VEA) by VRI, and amplitudes of relative impedance changes (rel.ΔZ) by EIT, were evaluated in seven regions of interest (ROIs). To assess the distribution of tidal volume (VT) by VRI and EIT, absolute values were normalized to the VT obtained by simultaneous spirometry measurements. Redistribution of ventilation by ALI and PEEP was detected by VRI and EIT. The linear correlation between pooled VT by VEA and rel.ΔZ was R2 = 0.96. Bland-Altman analysis showed a bias of −1.07±24.71 ml and limits of agreement of −49.05 to +47.36 ml. Within the different ROIs, correlations of VT-distribution by EIT and VRI ranged between R2 values of 0.29 and 0.96. ALI and PEEP did not alter the agreement of VT between VRI and EIT. Conclusions/Significance Measurements of regional ventilation distribution by VRI are comparable to those obtained by EIT. PMID:24475160

Emergency Departments (EDs) care for thousands of alcohol-intoxicated patients annually. No clinically relevant bedside measures currently exist to describe degree of impairment. To assess a group of bedside tests ("Hack's Impairment Index [HII] score") that applies a numerical value to the degree of alcohol-induced impairment in ED patients. A six-month retrospective review of HII score data was performed in a convenience sample of 293 intoxicated ED patients. Patients were scored 0-4 on five tasks, divided by the maximum score (20 if all tasks completed), every 2 hours; and classified by the number of visits: Low-frequency (1 visit); Medium-frequency (2 visits); High-frequency (≥3 visits). Correlations were assessed between HII score, healthcare provider judgment of intoxication, and measured alcohol levels. Study patients had 513 visits; 236 were low-frequency, 26 middle-frequency and 31 high-frequency. Clinical assessment and HII score were strongly correlated (Spearman's rho = 0.82, p < 0.001); clinical assessment and alcohol level less strongly so (rho = 0.49, p < 0.001). Among low-frequency patients, HII score and alcohol level were weakly correlated (r = 0.324, p < 0.001), with no such correlation among high-frequency visitors (r = -0.04, p = 0.89). The mean decline between serial HII scores was 0.126 (95% CI: 0.098-0.154). This pilot study shows the HII score can be performed at the bedside of alcohol-intoxicated patients. The HII declines in a reasonably predictable manner over time; and applies a quantitative, objective assessment of alcohol impairment.

Abstract Background Pain is common during cancer treatment, and patient self-reporting of pain is an essential first step for ideal cancer pain management. However, many studies on cancer pain management report that, because pain may be underestimated, it is often inadequately managed. Objective The aim of this study was to evaluate the effectiveness of bedside self-assessment of pain intensity for inpatients using a self-reporting pain board. Methods Fifty consecutive inpatients admitted to the Oncology Department of Chungbuk National University Hospital were included in this observational prospective study from February 2011 to December 2011. The medical staff performed pain assessments by asking patients questions and using verbal rated scales (VRS) over 3 consecutive days. Then, for 3 additional days, patients used a self-reporting pain board attached to the bed, which had movable indicators representing 0–10 on a numeric rating scale (NRS) and the frequency of breakthrough pain. Results Patient reliability over the medical staff's pain assessment increased from 74% to 96% after applying the self-reporting pain board (p=0.004). The gap (mean±standard deviation [SD]) between the NRS reported by patients and the NRS recorded on the medical records decreased from 3.16±2.08 to 1.00±1.02 (p<0.001), and the level of patient satisfaction with pain management increased from 54% to 82% (p=0.002). Conclusion This study suggests that the self-reporting bedside pain assessment tool provides a reliable and effective means of assessing pain in oncology inpatients. PMID:22974435

We assessed how often bedside stethoscopes in our intensive care unit were cleaned and whether they became colonised with potentially pathogenic bacteria. On two separate days the 12 nurses attending the bedspaces were questioned about frequency of stethoscope cleaning on the unit and the bedside stethoscopes were swabbed before and after cleaning to identify colonising organisms. Twenty-two health care providers entering the unit were asked the same questions and had their personal stethoscopes swabbed. All 32 non-medical staff cleaned their stethoscopes at least every day; however only three out of the 12 medical staff cleaned this often. Out of 24 intensive care unit bedside stethoscopes tested, two diaphragms and five earpieces were colonised with pathogenic bacteria. MRSA cultured from one earpiece persisted after cleaning. Three out of the 22 personal stethoscope diaphragms and five earpieces were colonised with pathogens. After cleaning, two diaphragms and two earpieces were still colonised, demonstrating the importance of regular cleaning.

This research examined bedside medication verification administration in 2 adult critical care units, using portable computers and permanent bedside computers. There were no differences in the number of near-miss errors, the time to administer the medications, or nurse perception of ease of medication administration, care of patients, or reliability of technology. The percentage of medications scanned was significantly higher with the use of permanent bedside computers, and nurses using permanent bedside computers were more likely to agree that the computer was always available.

Therapy with recombinant tissue plasminogen activator is underused in the treatment of ischemic stroke in rural hospitals, due to a lack of local stroke expertise. Telemedicine solutions for stroke are a level I, class A recommendation when a vascular neurologist is absent. However, current solutions require exorbitant startup costs, which are prohibitive for the rural hospitals in which they are needed most. This study demonstrates the efficacy of using the relatively inexpensive iPhone 4 in telestroke management. Twenty patients with stroke were assessed at the bedside using an iPhone 4, and each examination was directed remotely on another iPhone 4. Both the physician performing the bedside exam and the remote physician calculated a National Institutes of Health Stroke Scale (NIHSS) score for each patient. Each physician was blinded to the other's NIHSS score. In the 20 patients assessed, NIHSS scores ranged from 0 to 22. Interrater reliability assessed using the κ statistic demonstrated excellent agreement in 10 items (level of consciousness, month and age, visual fields, right motor arm, left motor arm, right motor leg, left motor leg, sensation, language, and neglect), moderate agreement in 3 items (gaze, facial palsy, and dysarthria), and poor agreement in 1 item (ataxia). Total NIHSS scores obtained remotely and at bedside showed an excellent level of agreement (intraclass correlation coefficient, 0.98). Our findings indicate that the iPhone 4 is an economical mobile solution that can be used to assess stroke patients remotely with high fidelity and can be readily incorporated into a telestroke network.

Capnography may provide useful non-invasive bedside information concerning heterogeneity in lung ventilation, ventilation-perfusion mismatching and metabolic status. Although the capnogram may be recorded by mainstream and sidestream techniques, the capnogram indices furnished by these approaches have not previously been compared systematically. Simultaneous mainstream and sidestream time and volumetric capnography was performed in anaesthetized, mechanically ventilated patients undergoing elective heart surgery. Time capnography was used to assess the phase II (SII,T) and III slopes (SIII,T). The volumetric method was applied to estimate phase II (SII,V) and III slopes (SIII,V), together with the dead space values according to the Fowler (VDF), Bohr (VDB), and Enghoff (VDE) methods and the volume of CO2 eliminated per breath ([Formula: see text]). The partial pressure of end-tidal CO2 ([Formula: see text]) was registered. Excellent correlation and good agreement were observed in SIII,T measured by the mainstream and sidestream techniques [ratio=1.05 (sem 0.16), R(2)=0.92, P<0.0001]. Although the sidestream technique significantly underestimated [Formula: see text] and overestimated SIII,V [1.32 (0.28), R(2)=0.93, P<0.0001], VDF, VDB, and VDE, the agreement between the mainstream and sidestream techniques in the difference between VDE and VDB, reflecting the intrapulmonary shunt, was excellent [0.97 (0.004), R(2)=0.92, P<0.0001]. The [Formula: see text] exhibited good correlation and mild differences between the mainstream and sidestream approaches [0.025 (0.005) kPa]. Sidestream capnography provides adequate quantitative bedside information about uneven alveolar emptying and ventilation-perfusion mismatching, because it allows reliable assessments of the phase III slope, [Formula: see text] and intrapulmonary shunt. Reliable measurement of volumetric parameters (phase II slope, dead spaces, and eliminated CO2 volumes) requires the application of a mainstream device. © The Author 2016.

To determine if physicians trained in ultrasound interpretation perceive a difference in image quality and usefulness between Extended Focused Assessment with Sonography ultrasound examinations performed at bedside in a hospital vs. by emergency medical technicians minimally trained in medical ultrasound on a moving ambulance and transmitted to the hospital via a novel wireless system. In particular, we sought to demonstrate that useful images could be obtained from patients in less than optimal imaging conditions; that is, while they were in transport. Emergency medical technicians performed the examinations during transport of blunt trauma patients. Upon patient arrival at the hospital, a bedside Extended Focused Assessment with Sonography examination was performed by a physician. Both examinations were recorded and later reviewed by physicians trained in ultrasound interpretation. Data were collected on 20 blunt trauma patients over a period of 13 mo. Twenty ultrasound-trained physicians blindly compared transmitted vs. bedside images using 11 Questionnaire for User Interaction Satisfaction scales. Four paired samples t-tests were conducted to assess mean differences between ratings for ambulatory and base images. Although there is a slight tendency for the average rating across all subjects and raters to be slightly higher in the base than in the ambulatory condition, none of these differences are statistically significant. These results suggest that the quality of the ambulatory images was viewed as essentially as good as the quality of the base images.

2018-05-01

Bedside hospital rounds promote patient-centered care in teaching and nonteaching settings. Patients and families prefer bedside rounds and provider acceptance is increasing. Efficient bedside rounds with an interprofessional team or with learners requires preparation of the patient and the rounding team. Bedside "choreography" provides structure and sets expectations for time spent in the room. By using relationship-centered communication, rounds can be both patient proximate and patient centered. The clinical examination can be integrated into the flow of the presentation and case discussion. Patient and provider experience can be enhanced through investing time at the bedside.

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.

BACKGROUND.: Our purpose was to evaluate the effectiveness of bedside sonography (US) in the detection of pneumothorax secondary to blunt thoracic trauma. METHODS.: In this prospective study, 240 hemithoraces of 120 consecutive patients with multiple trauma were evaluated with chest radiographs (CXR) and bedside thoracic US for the diagnosis of pneumothorax. CT examinations were performed in 68 patients. Fifty-two patients who did not undergo CT examinations were excluded from the study. US examinations were performed independently at bedside by two radiologists who were not informed about CXR and CT findings. CXRs were interpreted by two radiologists who were unaware of the US and CT results. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CXR and US were calculated. RESULTS.: One hundred thirty-six hemithoraces were assessed in 68 patients. A total of 35 pneumothoraces were detected in 33 patients. On US, the diagnosis of pneumothorax was correct in 32 hemithoraces. In 98 hemithoraces without pneumothorax, US was normal. With US examination, there were three false-positive and three false-negative results. The sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of US were 91.4%, 97%, 91.4%, 97%, and 97%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CXR were 82.7%, 89.7%, 68.5%, 95%, and 89.5%, respectively. CONCLUSIONS.: Bedside thoracic US is an accurate method that can be used in trauma patients instead of CXR for the detection of pneumothorax. Copyright © 2012 Wiley Periodicals, Inc.

Physiotherapy is an important part of treatment after severe brain injuries and stroke, but its effect on intracranial and systemic hemodynamics is minimally investigated. Therefore, the aim of this study was to assess the effects of an early bedside cycle exercise on intracranial and systemic hemodynamics in critically ill patients when admitted to a neurointensive care unit (NICU). Twenty critically ill patients suffering from brain injuries or stroke were included in this study performed in the NICU at Sahlgrenska University Hospital. One early implemented exercise session was performed using a bedside cycle ergometer for 20 min. Intracranial and hemodynamic variables were measured two times before, three times during, and two times after the bedside cycling exercise. Analyzed variables were intracranial pressure (ICP), cerebral perfusion pressure (CPP), mean arterial blood pressure (MAP), heart rate (HR), peripheral oxygen saturation (SpO 2 ), cardiac output (CO), stroke volume (SV), and stroke volume variation (SVV). The cycling intervention was conducted within 7 ± 5 days after admission to the NICU. Cycle exercise increased MAP (p = 0.029) and SV (p = 0.003) significantly. After exercise CO, SV, MAP, and CPP decreased significantly, while no changes in HR, SVV, SpO 2 , or ICP were noted when compared to values obtained during exercise. There were no differences in data obtained before versus after exercise. Early implemented exercise with a bedside cycle ergometer, for patients with severe brain injuries or stroke when admitted to a NICU, is considered to be a clinically safe procedure.

2018-01-01

Background The introduction of clinical information systems has increased the amount of clinical documentation. Although this documentation generally improves patient safety, it has become a time-consuming task for nurses, which limits their time with the patient. On the basis of a user-centered methodology, we have developed a mobile app named BEDSide Mobility to support nurses in their daily workflow and to facilitate documentation at the bedside. Objective The aim of the study was to assess the usability of the BEDSide Mobility app in terms of the navigation and interaction design through usability testing. Methods Nurses were asked to complete a scenario reflecting their daily work with patients. Their interactions with the app were captured with eye-tracking glasses and by using the think aloud protocol. After completing the tasks, participants filled out the system usability scale questionnaire. Descriptive statistics were used to summarize task completion rates and the users’ performance. Results A total of 10 nurses (aged 21-50) participated in the study. Overall, they were satisfied with the navigation, layout, and interaction design of the app, with the exception of one user who was unfamiliar with smartphones. The problems identified were related to the ambiguity of some icons, the navigation logic, and design inconsistency. Conclusions Besides the usability issues identified in the app, the participants’ results do indicate good usability, high acceptance, and high satisfaction with the developed app. However, the results must be taken with caution because of the poor ecological validity of the experimental setting.

In recent years, thanks to the development of miniaturized ultrasound devices, comparable to personal computers, tablets and even to smart phones, we have seen an increasing use of bedside ultrasound in internal medicine departments as a novel kind of ultrasound stethoscope. The clinical ultrasound-assisted approach has proved to be particularly useful in assessing patients with nodules of the neck, dyspnoea, abdominal pain, and with limb edema. In several cases, it has allowed a simple, rapid and precise diagnosis. Since 2005, the Italian Society of Internal Medicine and its Ultrasound Study Group has been holding a Summer School and training courses in ultrasound for residents in internal medicine. A national network of schools in bedside ultrasound was then organized for internal medicine specialists who want to learn this technique. Because bedside ultrasound is a user-dependent diagnostic method, it is important to define the limits and advantages of different new ultrasound devices, to classify them (i.e. Echoscopy and Point of Care Ultrasound), to establish appropriate different levels of competence and to ensure their specific training. In this review, we describe the point of view of the Italian Internal Medicine Society on these topics.

Bedside teaching is an important element of undergraduate medical education. However, the impact of curricular course structure on student outcome needs to be determined. This study assessed changes in fourth-year medical students' evaluations of clinical teaching sessions before and after the introduction of a new course format. The curricular structure of bedside teaching sessions in cardiology was modified without changing the amount of teaching time. Clinical teachers were instructed about the new teaching format and learning objectives. The new format implemented for adult but not paediatric cardiology sessions was piloted with 143 students in winter 2007/08. By computing effect sizes, evaluation results were compared to data obtained from 185 students before the intervention. Significant rating increases were observed for adult cardiology teaching sessions (Cohen's d = 0.66) but not paediatric cardiology sessions (d = 0.22). In addition to improving the structure and organization of the course, the intervention significantly impacted on students' perceptions of their learning outcome regarding practical skills (d = 0.69). Minimal curricular changes combined with basic faculty development measures significantly increase students' perception of learning outcome. Curricular structure needs to be considered when planning bedside teaching sessions in medical undergraduate training.

In this pilot study, we have evaluated bedside diffuse optical monitoring combining diffuse correlation spectroscopy and near-infrared diffuse optical spectroscopy to assess the effect of thrombolysis with an intravenous recombinant tissue plasminogen activator (rtPA) on cerebral hemodynamics in an acute ischemic stroke. Frontal lobes of five patients with an acute middle cerebral artery occlusion were measured bilaterally during rtPA treatment. Both ipsilesional and contralesional hemispheres showed significant increases in cerebral blood flow, total hemoglobin concentration and oxy-hemoglobin concentration during the first 2.5 hours after rtPA bolus. The increases were faster and higher in the ipsilesional hemisphere. The results show that bedside optical monitoring can detect the effect of reperfusion therapy for ischemic stroke in real-time.

Focused bedside ultrasound is rapidly becoming a standard of care to decrease the risks of complications related to invasive procedures. The purpose of this study was to assess whether adding to the curriculum of junior residents an educational intervention combining web-based e-learning and hands-on training would improve the residents' proficiency in different clinical applications of bedside ultrasound as compared to using the traditional apprenticeship teaching method alone. Junior residents (n = 39) were provided with two educational interventions (vascular and pleural ultrasound). Each intervention consisted of a combination of web-based e-learning and bedside hands-on training. Senior residents (n = 15) were the traditionally trained group and were not provided with the educational interventions. After the educational intervention, performance of the junior residents on the practical tests was superior to that of the senior residents. This was true for the vascular assessment (94% ± 5% vs. 68% ± 15%, unpaired student t test: p < 0.0001, mean difference: 26 (95% CI: 20 to 31)) and even more significant for the pleural assessment (92% ± 9% vs. 57% ± 25%, unpaired student t test: p < 0.0001, mean difference: 35 (95% CI: 23 to 44)). The junior residents also had a significantly higher success rate in performing ultrasound-guided needle insertion compared to the senior residents for both the transverse (95% vs. 60%, Fisher's exact test p = 0.0048) and longitudinal views (100% vs. 73%, Fisher's exact test p = 0.0055). Our study demonstrated that a structured curriculum combining web-based education, hands-on training, and simulation integrated early in the training of the junior residents can lead to better proficiency in performing ultrasound-guided techniques compared to the traditional apprenticeship model.

Ultrasound is a non-invasive and readily available tool that can be prospectively applied at the bedside to assess muscle mass in clinical settings. The four-site protocol, which images two anatomical sites on each quadriceps, may be a viable bedside method, but its ability to predict musculature has not been compared against whole-body reference methods. Our primary objectives were to (i) compare the four-site protocol's ability to predict appendicular lean tissue mass from dual-energy X-ray absorptiometry; (ii) optimize the predictability of the four-site protocol with additional anatomical muscle thicknesses and easily obtained covariates; and (iii) assess the ability of the optimized protocol to identify individuals with low lean tissue mass. This observational cross-sectional study recruited 96 university and community dwelling adults. Participants underwent ultrasound scans for assessment of muscle thickness and whole-body dual-energy X-ray absorptiometry scans for assessment of appendicular lean tissue. Ultrasound protocols included (i) the nine-site protocol, which images nine anterior and posterior muscle groups in supine and prone positions, and (ii) the four-site protocol, which images two anterior sites on each quadriceps muscle group in a supine position. The four-site protocol was strongly associated (R 2  = 0.72) with appendicular lean tissue mass, but Bland-Altman analysis displayed wide limits of agreement (-5.67, 5.67 kg). Incorporating the anterior upper arm muscle thickness, and covariates age and sex, alongside the four-site protocol, improved the association (R 2  = 0.91) with appendicular lean tissue and displayed narrower limits of agreement (-3.18, 3.18 kg). The optimized protocol demonstrated a strong ability to identify low lean tissue mass (area under the curve = 0.89). The four-site protocol can be improved with the addition of the anterior upper arm muscle thickness, sex, and age when predicting appendicular lean tissue mass. This optimized protocol can accurately identify low lean tissue mass, while still being easily applied at the bedside. © 2017 The Authors.

Abstract Background Ultrasound is a non‐invasive and readily available tool that can be prospectively applied at the bedside to assess muscle mass in clinical settings. The four‐site protocol, which images two anatomical sites on each quadriceps, may be a viable bedside method, but its ability to predict musculature has not been compared against whole‐body reference methods. Our primary objectives were to (i) compare the four‐site protocol's ability to predict appendicular lean tissue mass from dual‐energy X‐ray absorptiometry; (ii) optimize the predictability of the four‐site protocol with additional anatomical muscle thicknesses and easily obtained covariates; and (iii) assess the ability of the optimized protocol to identify individuals with low lean tissue mass. Methods This observational cross‐sectional study recruited 96 university and community dwelling adults. Participants underwent ultrasound scans for assessment of muscle thickness and whole‐body dual‐energy X‐ray absorptiometry scans for assessment of appendicular lean tissue. Ultrasound protocols included (i) the nine‐site protocol, which images nine anterior and posterior muscle groups in supine and prone positions, and (ii) the four‐site protocol, which images two anterior sites on each quadriceps muscle group in a supine position. Results The four‐site protocol was strongly associated (R 2 = 0.72) with appendicular lean tissue mass, but Bland–Altman analysis displayed wide limits of agreement (−5.67, 5.67 kg).

Evaluation is an integral part of curriculum development in medical education. Given the peculiarities of bedside teaching, specific evaluation tools for this instructional format are needed. Development of these tools should be informed by appropriate frameworks. The purpose of this study was to develop a specific evaluation tool for bedside teaching based on the Stanford Faculty Development Program's clinical teaching framework. Based on a literature review yielding 47 evaluation items, an 18-item questionnaire was compiled and subsequently completed by undergraduate medical students at two German universities. Reliability and validity were assessed in an exploratory full information item factor analysis (study one) and a confirmatory factor analysis as well as a measurement invariance analysis (study two). The exploratory analysis involving 824 students revealed a three-factor structure. Reliability estimates of the subscales were satisfactory (α = 0.71-0.84). The model yielded satisfactory fit indices in the confirmatory factor analysis involving 1043 students. The new questionnaire is short and yet based on a widely-used framework for clinical teaching. The analyses presented here indicate good reliability and validity of the instrument. Future research needs to investigate whether feedback generated from this tool helps to improve teaching quality and student learning outcome.

Body composition analysis techniques in adult and pediatric patients: how reliable are they? How useful are they clinically?

PubMed

Woodrow, Graham

2007-06-01

Complex abnormalities of body composition occur in peritoneal dialysis (PD). These abnormalities reflect changes in hydration, nutrition, and body fat, and they are of major clinical significance. Clinical assessment of these body compartments is insensitive and inaccurate. Frequently, simultaneous changes of hydration, wasting, and body fat content can occur, confounding clinical assessment of each component. Body composition can be described by models of varying complexity that use one or more measurement techniques. "Gold standard" methods provide accurate and precise data, but are not practical for routine clinical use. Dual energy X-ray absorptiometry allows for measurement of regional as well as whole-body composition, which can provide further information of clinical relevance. Simpler techniques such as anthropometry and bioelectrical impedance analysis are suited to routine use in clinic or at the bedside, but may be less accurate. Body composition methodology sometimes makes assumptions regarding relationships between components, particularly in regard to hydration, which may be invalid in pathologic states. Uncritical application of these methods to the PD patient may result in erroneous interpretation of results. Understanding the foundations and limitations of body composition techniques allows for optimal application in clinical practice.

Bedside evaluation of dysphagia may be challenging in left middle cerebral artery (MCA) stroke due to frequently existing aphasia. Here we analyse the predictive value of common bedside screening tests and of two items of cortical dysfunction, aphasia and buccofacial apraxia (BFA), for the detection of dysphagia. We prospectively examined 67 consecutive patients with clinical and imaging evidence of acute (<72 h) left MCA stroke. Dysphonia, dysarthria, abnormal volitional cough and abnormal gag reflex were assessed followed by a standardized 50-ml water-swallowing test determining the symptoms cough and voice change after swallow. Aphasia and BFA were assessed according to defined criteria. Fibre-optic endoscopic evaluation of swallowing (FEES) was performed for validation of dysphagia. 41 (61%) patients had FEES-proven dysphagia. Abnormal gag reflex, abnormal volitional cough, cough after swallow, aphasia and BFA were significantly more frequent in dysphagic as compared to non-dysphagic patients, while dysphonia, dysarthria and voice change after swallow were not. Aphasia and BFA had the highest sensitivity (97 and 78%, respectively) and high negative predictive values (89 and 68%, respectively) for dysphagia. Multivariate regression analysis did not identify an independent predictor of dysphagia. In left MCA stroke, the sensitivity and specificity of common bedside dysphagia screening methods are low. In contrast, aphasia and BFA have a high sensitivity and high negative predictive power, presumably due to the neuro-anatomical overlap between cortical regions involved in swallowing, speech production, imitation and voluntary movement control. © 2014 S.

The introduction of clinical information systems has increased the amount of clinical documentation. Although this documentation generally improves patient safety, it has become a time-consuming task for nurses, which limits their time with the patient. On the basis of a user-centered methodology, we have developed a mobile app named BEDSide Mobility to support nurses in their daily workflow and to facilitate documentation at the bedside. The aim of the study was to assess the usability of the BEDSide Mobility app in terms of the navigation and interaction design through usability testing. Nurses were asked to complete a scenario reflecting their daily work with patients. Their interactions with the app were captured with eye-tracking glasses and by using the think aloud protocol. After completing the tasks, participants filled out the system usability scale questionnaire. Descriptive statistics were used to summarize task completion rates and the users' performance. A total of 10 nurses (aged 21-50) participated in the study. Overall, they were satisfied with the navigation, layout, and interaction design of the app, with the exception of one user who was unfamiliar with smartphones. The problems identified were related to the ambiguity of some icons, the navigation logic, and design inconsistency. Besides the usability issues identified in the app, the participants' results do indicate good usability, high acceptance, and high satisfaction with the developed app. However, the results must be taken with caution because of the poor ecological validity of the experimental setting. ©Frederic Ehrler, Thomas Weinhold, Jonathan Joe, Christian Lovis, Katherine Blondon.

The purpose of this study was to examine the effectiveness of a Transforming Care at the Bedside initiative from a unit perspective. Improving patient outcomes and nurses' work environments are the goals of Transforming Care at the Bedside. Transforming Care at the Bedside creates programs of change originating at the point of care and directly promoting engagement of nurses to transform work processes and quality of care on medical-surgical units. This descriptive comparative study draws on multiple data sources from two nursing units: a Transforming Care at the Bedside unit where staff tested, adopted and implemented improvement ideas, and a control unit where staff continued traditional practices. Change theory provided the framework for the study. Direct care and value-added care increased on Transforming Care at the Bedside unit compared with the control unit. Transforming Care at the Bedside unit decreased in incidental overtime. Nurses reported that the process challenged old ways of thinking and increased nursing innovations. Hourly rounding, bedside reporting and the use of pain boards were seen as positive innovations. Evidence supported the value-added dimension of the Transforming Care at the Bedside process at the unit level. Nurses recognized the significance of their input into processes of change. Transformational leadership and frontline projects provide a vehicle for innovation through application of human capital. © 2012 Blackwell Publishing Ltd.

The purpose of this study was to evaluate the effectiveness of bedside nursing report implementation on a pediatric neuroscience unit. The change-of-shift nursing report often involves only nurse-to-nurse communication, occurs far away from the patient's bedside, and includes little or no patient/family involvement. Studies show that the bedside nursing report is a more comprehensive and patient-centered approach (C. D. Anderson & R. R. Mangino, 2006). Patient and nurse satisfaction and nursing overtime were measured 6 months before and 6 months after the implementation of bedside reporting. Data were analyzed using paired t test, chi-square test, and Fisher's exact tests to determine significant changes. Patients, families, and nurses reported an increase in satisfaction after the implementation of bedside reporting. Overtime decreased and represented a potential cost savings of nearly $13,000 annually. Bedside reporting saves money, improves patient and nurse satisfaction, and is a more comprehensive approach to change-of-shift reporting.

Modern cancer therapy is more individualized to specific cancer subtypes, in an attempt to treat those patients who are likely to obtain greater benefit and avoid treatment induced side effects in those who will not. Nanotechnology heralds an era whereby cancer could be diagnosed by a single agent, treated simultaneously while the diagnosis is being made, and its response to treatment monitored. Whilst nanotechnology is still mostly in the research stage, several applications are ready for translation from the bench to the bedside, in particular in the field of breast cancer. This is exciting new area of research where science fiction may become a reality.

Bedside teaching is a vital component of medical education. It is applicable to any situation where teaching is imparted in the presence of patients. In teaching in the patients’ presence, learners have the opportunities to use all of their senses and learn the humanistic aspect of medicine such as role modeling, which is vital but difficult to communicate in words. Unfortunately, bedside teaching has been on the decline. To investigate the reasons for the decline in bedside teaching, its importance and its revival, a review of literature was carried out using PubMed and other data bases. The review revealed that the major concerns of bedside teaching were time constraint, false preceptors’ concern about patients’ comfort, short stay of patients in hospitals, learner distraction by technology, lack of experience and unrealistic faculty expectation. Whatsoever the reasons, bedside teaching cannot be replaced with anything else. There are newer approaches of effective bedside teaching, and the core focus of all such approaches is educational process. A bedside teacher must learn how to involve patients and learners in the educational processes. Moreover, bedside teaching is the process through which learners acquire the skills of communication by asking patients’ permission, establishing ground rules, setting time limit, introducing the team, diagnosing learner, diagnosing patient, conducting focused teaching, using simple language, asking patient if there is any question, closing with encouraging thanks, and giving feedback privately. It is most important to ensure a comfortable environment for all participants, the learner, the patient and the bedside teacher. Ongoing faculty development programs on educational processes and realistic faculty expectations may overcome the problems. PMID:23365470

The HemoCue B-hemoglobin test system (HemoCue, Inc., Mission Viejo, CA) is a photometric method for rapid bedside determination of hemoglobin (Hb). We compared the performance of HemoCue measured Hb against Coulter STK-S (CSTK) measured Hb in chronic hemodialysis (HD) patients in two different settings. In the first setting, Hemocue analysis was performed by multiple HD technicians (n = 132). In the second setting, a nurse trained in proper specimen handling performed the HemoCue analysis (n = 74). Simultaneous measurement of Hb by the CSTK method was performed. First setting: Hb was 11.1+/-1.66 (SD) g/dl by CSTK and 11.7+/-2.29 g/dl by HemoCue. The HemoCue method consistently overestimated Hb by an average (SD) of 0.63 (1.267) g/dl (95% CI = 0.42 to 0.85). Hb was overestimated in 25.7% and underestimated in 2.3% of the patients by 1 g/dl or more. Thus, the HemoCue system was accurate within 1 g/dl only 72% of the time. Second setting: HemoCue overestimated Hb by an average (SD) of 0.29 (0.52) g/dl (95% CI, 0.17 to 0.41). Only 4% of all patients had errors in estimation of 1 g/dl or more. Thus, HemoCue was accurate in 96% of the patients within 1 g/dl. After reviewing the two protocols, the primary difference in the two studies was the technique used to obtain the specimens. When performed properly, Hb testing using the HemoCue testing system had a high level of agreement with CSTK. Appropriate training in specimen handling, as well as test performance, will increase accuracy and reliability of bedside hemoglobinometry.

Pulmonary embolism (PE) is a frequently occurring complication in critically ill patients, and the simultaneous occurrence of PE and life-threatening bleeding is a therapeutic dilemma. Inferior vena cava filters (IVCF) may represent an important therapeutic alternative in these cases. The Angel® catheter (Bio2 Medical Inc., San Antonio, TX, USA) is a novel IVCF that provides temporary protection from PE and is implanted at bedside without fluoroscopy. The European Angel® Catheter Registry is an observational, multicenter study. In our German substudy, we investigated patients from three German hospitals and four intensive care units, who underwent Angel® catheter implantation between February 2016 and December 2016. A total of 23 critically ill patients (68 ± 9 years, 43% male) were included. The main indication for implantation was a high risk for or an established PE, combined with contraindications for prophylactic or therapeutic anticoagulation due to either an increased risk of bleeding (81%) or active bleeding (13%). The Angel® catheter was successfully inserted in all patients at bedside. No PE occurred in patients with an indwelling Angel® catheter. Clots with a diameter larger the 20 mm, indicating clot migration, were detected in 5% of the patients by cavography before filter retrieval. Filter retrieval was uneventful in all of our cases, while filter dislocation occurred in 3% of the patients. The German data from the multicenter European Angel® Catheter Registry show that the Angel® catheter is a safe and effective approach for critically ill patients with a high risk for the development of PE or an established PE, when an anticoagulation therapy is contraindicated.

Bedside reporting continues to gain much attention and is being investigated to support the premise that "hand-off" communications enhance efficacy in delivery of patient care. Patient inclusion in shift reports enhances good patient outcomes, increased satisfaction with care delivery, enhanced accountability for nursing professionals, and improved communications between patients and their direct care providers. This article discusses the multiple benefits of dynamic dialogue between patients and the health care team, challenges often associated with bedside reporting, and protocols for managing bedside reporting with the major aim of improving patient care.

Abstract In recent years, pathophysiology and clinical impact of microvascular fluid filtration has regained interest. As the latest data in surgical patients have been published almost 20 years ago, there is need for further research to better understand fluid filtration during the perioperative period. Venous congestion plethysmography (VCP) provides a rapid and noninvasive method, which has been shown suitable for the assessment of fluid filtration in limbs. Fluid filtration assessed by VCP can be obtained from forearm and calf measurement sites, while in many clinical situations a reduced access to the patient often restricts the measurements to patient's forearm. We aimed to investigate if fluid filtration obtained from forearm and calf measurement site is interchangeable in nonsedated perioperative patients. Fluid filtration by VCP was obtained simultaneously from forearm and calf in patients with ovarian cancer at 4 time points during the perioperative course and assessed by the difference of volume changes of the limb between third and sixth minutes (VC6-3min) during venous congestion. VC6-3min obtained from forearm and calf measurement sites was compared with respect to agreement and evaluated regarding the association with the presence of leg edema. A total of 74 paired measurements were analyzed in 29 patients. Forearm VC6-3min was significantly higher than calf VC6-3min (median [25th; 75th quartile], 0.6 (0.4; 0.9) vs 0.4 [0.3; 0.6] %, P = 0.008). Bland–Altman and Polar analysis revealed a poor agreement between forearm and calf VC6-3min at predefined time points and changes of VC6-3min during the perioperative course (bias +0.23%, limits of agreement [LOA] −1.1% to 1.6%; angular bias −2.5°, radial LOA −82° to +77°). Forearm VC6-3min was significantly increased in patients with presence of leg edema (0.7 (0.5; 1.0) vs 0.5 (0.4; 0.6) %, P < 0.001) while calf VC6-3min did not differ in patients with and without edema. This study indicates that forearm and calf measurement sites are not interchangeable when bedside assessing fluid filtration by VCP in nonsedated perioperative patients. Considering that only forearm fluid filtration was related to the presence of edema, forearm measurement site should be chosen as a primary site for assessing fluid filtration. PMID:28248863

We evaluated the feasibility and the patient acceptability of integrating a kiosk into routine emergency department (ED) practice for offering HIV testing. The work was conducted in four phases: phase 1 was a baseline, in which external testing staff offered testing at the bedside; phase 2 was a pilot assessment of a prototype kiosk; phase 3 was a pilot implementation and phase 4 was the full implementation with automated login. Feasibility was assessed by the proportion of offering HIV tests, acceptance, completion and result reporting. During the study period, the number of ED patients and eligible patients for screening were similar in the three main phases. However, the number and proportion of patients offered testing of those eligible for screening increased significantly from phase 1 (32%) to phase 3 (37%) and phase 4 (40%). There were slightly higher prevalences of newly diagnosed HIV with kiosk versus bedside testing (phase 1, 0%; phase 3, 0.2%; phase 4, 0.5%). Compared to patients tested at the bedside, patients tested via the kiosk were significantly younger, more likely to be female, to be black, and to report high risk behaviours. ED-based HIV screening via a registration-based kiosk was feasible, yielded similar proportions of testing, and increased the proportion of engagement of higher-risk patients in testing. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The Clock-Drawing Test (CDT) is a brief, relatively time-efficient, easy to administer at bedside, and well-proven cognitive screening test that assesses a broad range of cognitive abilities in stroke, delirium, and dementia. However, challenges of comprehensive therapeutic outcome evaluations in schizophrenia can also be potentially overcome using CDT. The authors aimed to measure the therapeutic outcome using CDT in 101 schizophrenia patients, irrespective of their diagnostic subtypes. A repeated measures analysis of variance found that improvements on CDT and the Positive and Negative Syndrome Scale were closely correlated, reflecting critical information about therapeutic response measures in schizophrenia.

Objective: To investigate the value of bedside echocardiography in diagnosis and risk assessment of in-hospital death of patients with Stanford type A aortic dissection. Methods: The clinical data of 229 patients with Stanford type A aortic dissection diagnosed by CT angiography in Zhongshan Hospital affiliated to Fudan University between January 2009 and January 2016 were retrospectively analyzed. The patients were divided into survival group(191 cases)and non-survival group(38 cases)according to presence or absence of in-hospital death. The bedside echocardiography features were analyzed, and influence factors of in-hospital death were determined by multivariate logistic regression analysis. Results: (1) Compared with the survival group, the non-survival group had lower surgery rate (60.52%(23/38) vs. 85.34%(163/191), P <0.01). Age, gender and Debakey classification were similar between survival group and death group (all P >0.05). (2) The bedside echocardiography results showed that prevalence of aortic valve involvement(65.79%(25/38) vs.34.03%(65/191), P <0.01) and severe aortic regurgitation (44.74%(17/38) vs. 14.14%(27/191), P <0.01) were significantly higher in non-survival group than in survival group. The non-survival group had larger aortic root diameter than the survival group ((55.5±6.4)mm vs. (42.3±7.8)mm, P <0.01). There were no significant differences in pericardial effusion, expansion of aortic sinus, and left ventricular ejection fraction between survival group and non-survival group (all P >0.05). (3) The multivariate logistic regression analysis showed that aortic valve involvement( OR =3.275, 95% CI 1.290-8.313, P <0.05), aortic root diameter( OR =1.202, 95% CI 1.134-1.275, P <0.01), and surgery ( OR =0.224, 95% CI 0.079-0.629, P <0.01) were independent risk factors for in-hospital death in patients with Stanford type A aortic dissection. Conclusions: Bedside echocardiography has significant diagnostic value for Stanford type A aortic dissection. Aortic valve involvement, enlargement of aortic root diameter and without surgery are independent risk factors for patients with Stanford type A aortic dissection.

To construct a calculator for 'bedside' estimation of morbidly adherent placenta (MAP) risk based on ultrasound (US) findings. This retrospective study included all pregnant women with at least one previous cesarean delivery attending in our US unit between December 2013 and January 2017. The examination was based on a scoring system which determines the probability for MAP. The study population included 471 pregnant women, and 41 of whom (8.7%) were diagnosed with MAP. Based on ROC curve, the most effective US criteria for detection of MAP were the presence of the placental lacunae, obliteration of the utero-placental demarcation, and placenta previa. On the multivariate logistic regression analysis, US findings of placental lacunae (OR = 3.5; 95% CI, 1.2-9.5; P = 0.01), obliteration of the utero-placental demarcation (OR = 12.4; 95% CI, 3.7-41.6; P < 0.0001), and placenta previa (OR = 10.5; 95% CI, 3.5-31.3; P < 0.0001) were associated with MAP. By combining these three parameters, the receiver operating characteristic curve was calculated, yielding an area under the curve of 0.93 (95% CI, 0.87-0.97). Accordingly, we have constructed a simple calculator for 'bedside' estimation of MAP risk. The calculator is mounted on the hospital's internet website ( http://www.assafh.org/Pages/PPCalc/index.html ). The risk estimation of MAP varies between 1.5 and 87%. The present calculator enables a simple 'bedside' MAP estimation, facilitating accurate and adequate antenatal risk assessment.

This study aimed to derive specific user requirements and barriers in a real medical environment to define the essential elements and functions of two types of point-of-care (POC) robot: a telepresence robot as a tool for teleconsultation, and a bedside robot to provide emotional care for patients. An analysis of user requirements was conducted; user needs were gathered and identified, and detailed, realistic scenarios were created. The prototype robots were demonstrated in physical environments for envisioning and evaluation. In all, three nurses and three clinicians participated as evaluators to observe the demonstrations and evaluate the robot systems. The evaluators were given a brief explanation of each scene and the robots' functionality. Four major functions of the teleconsultation robot were defined and tested in the demonstration. In addition, four major functions of the bedside robot were evaluated. Among the desired functions for a teleconsultation robot, medical information delivery and communication had high priority. For a bedside robot, patient support, patient monitoring, and healthcare provider support were the desired functions. The evaluators reported that the teleconsultation robot can increase support from and access to specialists and resources. They mentioned that the bedside robot can improve the quality of hospital life. Problems identified in the demonstration were those of space conflict, communication errors, and safety issues. Incorporating this technology into healthcare services will enhance communication and teamwork skills across distances and thereby facilitate teamwork. However, repeated tests will be needed to evaluate and ensure improved performance.

2017-12-01

This study examines what prompts the intensive care unit (ICU) nurse to go to the patient's bedside to investigate an alarm and the influences on the nurse's determination regarding how quickly this needs to occur. A qualitative descriptive design guided data collection and analysis. Individual semi-structured interviews were conducted. Thematic analysis guided by the Patient Risk Detection Theoretical Framework was applied to the data. Four specialty intensive care units in an academic medical center. ICU nurses go the patient's bedside in response to an alarm to catch patient deterioration and avert harm. Their determination of the immediacy of patient risk and their desire to prioritize their bedside investigations to true alarms influences how quickly they proceed to the bedside. Ready visual access to physiological data and waveform configurations, experience, teamwork, and false alarms are important determinants in the timing of ICU nurses' bedside alarm investigations.

Echocardiography-guided pericardiocentesis is the first choice method for relieving cardiac tamponade, but the exact role of the echocardiography at the moment of the puncture is still controversial. In this report, detailed echocardiographic evaluation was performed in 21 consecutive patients with cardiac tamponade just before the pericardiocentesis. Appropriate needle position was determined according to the probe position using imaginary x, y, and z axes. Pericardiocentesis was performed successfully using this technique without simultaneous echocardiography and no complications were observed. We concluded that bedside echocardiography with detailed evaluation of the puncture site and angle is enough for pericardiocentesis instead of real time guiding. © 2013, Wiley Periodicals, Inc.

Background Due to increasing time constraints, the use of bedside presentations in resident education has declined. We examined whether patient satisfaction in the emergency department is affected when first-year residents present at the bedside with attendings. Methods We performed an observational, prospective, nonblinded study in the emergency department of a military teaching hospital. We alternately assigned first-year residents to present a convenience sample of 248 patients to the attending physician at the patient's bedside or away from the patient. We measured patient satisfaction by using the Patient Satisfaction Questionaire-18 (PSQ-18), a validated survey instrument that utilizes a Likert scale, and additional nonvalidated survey questions involving Likert and visual analog scales. Results While the median PSQ-18 score of 74 (95% confidence interval [CI], 72–76) was higher for patient satisfaction when residents made bedside presentations than that for standard presentations, 72 (95% CI, 70–74), the difference did not reach statistical significance (P  =  .33). Conclusion There was no significant difference in overall patient satisfaction between residents' bedside presentations and presentations to attendings away from the patient. Although not significant, the differences noted in PSQ-18 subscales of communication, general satisfaction, and interpersonal manner warrant further investigation. Patients did not appear to be uncomfortable with having their care discussed and with having subsequent resident education at the bedside. Future research on patient satisfaction after implementation of standardized bedside teaching techniques 5 help further elucidate this relationship. PMID:23205195

At the University of Colorado Hospital, nurse-to-nurse shift reports traditionally occurred in a conference room setting and consisted of nurse-to-nurse verbal communication. Evidence supports moving this information exchange to the patient bedside. This model of report improves clinical effectiveness, patient safety, nurse efficiency, and staff satisfaction. Bedside reporting empowers patients and families to ask questions and contribute to their plan of care and increases patient satisfaction. This article describes the process of implementing and evaluating a model of nurse-to-nurse bedside handoff report.

The present study aims at the development of a new concept system that will contribute toward improving the quality of life for bedridden patients and the elderly. The results of a basic study showed the possibility of a virtual reality system reducing stress and pain, provided VR sickness does not occur. A Bedside Wellness System which lets a person experience a virtual forest walk and provides a facility of rehabilitation was proposed based on the basic study and developed. An experiment to assess the developed system using healthy subjects was executed. The data suggested the positive effects of the system; however, some points to be improved were also extracted. After a few improvements, the system will be available for clinical use.

Recognizing Bedside Events Using Thermal and Ultrasonic Readings

Falls in homes of the elderly, in residential care facilities and in hospitals commonly occur in close proximity to the bed. Most approaches for recognizing falls use cameras, which challenge privacy, or sensor devices attached to the bed or the body to recognize bedside events and bedside falls. We use data collected from a ceiling mounted 80 × 60 thermal array combined with an ultrasonic sensor device. This approach makes it possible to monitor activity while preserving privacy in a non-intrusive manner. We evaluate three different approaches towards recognizing location and posture of an individual. Bedside events are recognized using a 10-second floating image rule/filter-based approach, recognizing bedside falls with 98.62% accuracy. Bed-entry and exit events are recognized with 98.66% and 96.73% accuracy, respectively. PMID:28598394

Bedside Optic Nerve Sheath Diameter Assessment in the Identification of Increased Intracranial Pressure in Suspected Idiopathic Intracranial Hypertension.

2016-01-01

We determined whether the bedside assessment of the optic nerve sheath diameter could identify elevated intracranial pressure in individuals with suspected idiopathic intracranial hypertension. This was a single-center, prospective, rater-blinded study performed in a freestanding pediatric teaching hospital. Patients aged 12 to 18 years scheduled for an elective lumbar puncture with the suspicion of idiopathic intracranial hypertension were eligible to participate. Optic nerve sheath diameter was measured via ultrasonography before performing a sedated lumbar puncture for measuring cerebrospinal fluid opening pressure. Abnormal measurements were predefined as optic nerve sheath diameter ≥4.5 mm and a cerebrospinal fluid opening pressure greater than 20 cmH2O. Thirteen patients participated in the study, 10 of whom had elevated intracranial pressure. Optic nerve sheath diameter was able to predict or rule out elevated intracranial pressure in all patients. Noninvasive assessment of the optic nerve sheath diameter could help to identify patients with elevated intracranial pressure when idiopathic intracranial hypertension is suspected.

In robotic surgery, the coordination between the console-side surgeon and bed-side assistant is crucial, more than in standard surgery or laparoscopy where the surgical team works in close contact. Xperience™ Team Trainer (XTT) is a new optional component for the dv-Trainer ® platform and simulates the patient-side working environment. We present preliminary results for face, content, and the workload imposed regarding the use of the XTT virtual reality platform for the psychomotor and communication skills training of the bed-side assistant in robot-assisted surgery. Participants were categorized into "Beginners" and "Experts". They tested a series of exercises (Pick & Place Laparoscopic Demo, Pick & Place 2 and Team Match Board 1) and completed face validity questionnaires. "Experts" assessed content validity on another questionnaire. All the participants completed a NASA Task Load Index questionnaire to assess the workload imposed by XTT. Twenty-one consenting participants were included (12 "Beginners" and 9 "Experts"). XTT was shown to possess face and content validity, as evidenced by the rankings given on the simulator's ease of use and realism parameters and on the simulator's usefulness for training. Eight out of nine "Experts" judged the visualization of metrics after the exercises useful. However, face validity has shown some weaknesses regarding interactions and instruments. Reasonable workload parameters were registered. XTT demonstrated excellent face and content validity with acceptable workload parameters. XTT could become a useful tool for robotic surgery team training.

Symptoms and signs of neuro-otologic disorders.

PubMed

Newman-Toker, David E

2012-10-01

Symptoms and signs of neuro-otologic disorders are critical components in the diagnostic assessment of patients with vestibular symptoms such as vertigo, dizziness, unsteadiness, and oscillopsia. Most diagnoses can be accomplished at the bedside. An understanding of key diagnostic principles is essential for all practicing neurologists, who are often faced with determining whether such patients warrant urgent diagnostic testing or hospital admission. This article introduces readers to core concepts and recent advances in the understanding of directed history taking and physical examination in patients with vestibular symptoms or suspected neuro-otologic disorders. International consensus definitions for vestibular symptoms have recently been published. During the past 5 years, a growing body of scientific evidence has demonstrated that the traditional approach to bedside diagnosis of patients with vertigo and dizziness is inadequate. Former teaching that history taking should first rely on categorizing symptoms by type (eg, vertigo, presyncope, disequilibrium, nonspecific dizziness) has been replaced by an emphasis on categorizing timing and triggers for vestibular symptoms, which focuses the clinician's attention on four key syndromic patterns: (1) acute, spontaneous, prolonged vestibular symptoms; (2) episodic, positional vestibular symptoms; (3) episodic, spontaneous vestibular symptoms; and (4) chronic unsteadiness (with or without oscillopsia). Each of these categories delineates a relatively narrow differential diagnosis within which a focused examination distinguishes between benign common causes and dangerous uncommon ones. A focused approach to bedside assessment of patients with vestibular symptoms is essential for accurate and efficient diagnosis. All neurologists should be aware of major recent advances.

To determine the feasibility of using UltraFast Doppler in post-operative evaluation of the hepatic artery (HA) after liver transplantation (LT), we evaluated 283 simultaneous conventional and UltraFast Doppler sessions in 126 recipients over a 2-mo period after LT, using an Aixplorer scanner The Doppler indexes of the HA (peak systolic velocity [PSV], end-diastolic velocity [EDV], resistive index [RI] and systolic acceleration time [SAT]) by retrospective analysis of retrieved waves from UltraFast Doppler clips were compared with those obtained by conventional spectral Doppler. Correlation, performance in diagnosing the pathologic wave, examination time and reproducibility were evaluated. The PSV, EDV, RI and SAT of spectral and UltraFast Doppler measurements exhibited excellent correlation with favorable diagnostic performance. During the bedside examination, the mean time spent for UltraFast clip storing was significantly shorter than that for conventional Doppler US measurements. Both conventional and UltraFast Doppler exhibited good to excellent inter-analysis consistency. In conclusion, compared with conventional spectral Doppler, UltraFast Doppler values correlated excellently and yielded acceptable pathologic wave diagnostic performance with reduced examination time at the bedside and excellent reproducibility.

Leukocyte recruitment and adhesion to the endothelium are hallmarks of systemic inflammation that manifest in a wide range of diseases. At present, no method is available to directly measure leukocyte kinetics at the bedside. In this study, we validate a new method to identify and quantify microcirculatory leukocytes observed by handheld vital microscopy (HVM) using space-time diagram (STD) analysis. Video clips (N=59) containing one capillary-post capillary venule (C-PCV) unit where leukocytes could be observed emanating from a capillary into a venule in cardiac surgery patients (N=20) were included. STD analysis and manual counting were used to quantify the number of leukocytes (total, rolling and non-rolling). Pearson's correlation and Bland-Altman analysis were used to determine agreement between the STDs and manual counting. For reproducibility, intra- and inter-observer coefficients of variation (CVs) were assessed. Leukocyte (rolling and non-rolling) and red blood cell velocities were assessed. The STDs and manual counting procedures for the quantification of rolling leukocytes showed good agreement (r=0.8197, P<0.0001), with a Bland-Altman analysis mean difference of -0.0 (-6.56; 6.56). The overall intra-observer CV for the STD method was 1.5%. The overall inter-observer CVs for the STD and the manual method were 5.6% and 9.4%, respectively. The non-rolling velocity was significantly higher than the rolling velocity (812{plus minus}519 µm/s vs 201{plus minus}149 µm/s, P=0.001). The STD results agreed with the manual counting procedure results, had a better reproducibility and could assess the leukocyte velocity. STD analysis using bedside HVM imaging presented a new methodology for quantifying leukocyte kinetics and functions in the microcirculation.

There is a glaring lack of published evidence-based strategies to improve the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) patient experience scores on the physician domain. Strategies that have been used are resource intensive and difficult to sustain. We hypothesized that prompting providers to assess their own etiquette-based practices every 2 weeks over the course of 1 year would improve patient experience on the physician domain. Randomized controlled trial. 4 acute care hospitals. Hospitalists. Hospitalists were randomized to the study or the control arm. The study arm was prompted every 2 weeks for 12 months to report how frequently they engaged in 7 best-practice bedside etiquette behaviors. Control arm participants received similarly worded questions on quality improvement behaviors. Provider experience scores were calculated from the physician HCAHPS and Press Ganey survey provider items. Physicians reported high rates of etiquette-based behavior at baseline, and this changed modestly over the study period. Self-reported etiquette behaviors were not associated with experience scores. The difference in difference analysis of the baseline and postintervention physician experience scores between the intervention arm and the control arm was not statistically significant (P = 0.71). In this 12-month study, biweekly reflection and reporting of best-practice bedside etiquette behaviors did not result in significant improvement on physician domain experience scores. It is likely that hospitalists' self-assessment of their bedside etiquette may not reflect patient perception of these behaviors. Furthermore, hospitalists may be resistant to improvement in this area since they rate themselves highly at baseline.

Bedside ultrasonography (US) measurement of the inferior vena cava (IVC) and aorta (Ao) may be useful in objectively assessing children with dehydration. The objectives of this study were 1) to compare the IVC and Ao diameters (IVC/Ao) ratio of dehydrated children with controls and 2) to compare the IVC/Ao ratio before and after intravenous (i.v.) rehydration in children with dehydration. This prospective observational study was performed in an urban pediatric emergency department. Children between 6 months and 16 years of age with clinical evidence of dehydration were enrolled. Bedside US measurements of the IVC and Ao were taken before and immediately after i.v. fluids were administered. An age-, gender-, and weight-matched control without dehydration was enrolled for each subject. The IVC/Ao ratios of subjects and controls were compared using Wilcoxon signed rank test, as were the ratios before and after i.v. hydration for each subject. Thirty-six pairs of subjects and matched controls were enrolled. The IVC/Ao ratios in the subjects were lower as compared with controls (mean of 0.75 vs. 1.01), with a mean difference of 0.26 (95% confidence interval = 0.18 to 0.35). In subjects, the IVC/Ao ratios were significantly lower before i.v. hydration (mean of 0.75 vs. 1.09), with a mean difference of 0.34 (95% confidence interval = 0.29 to 0.39). As measured by bedside US measurement, the IVC/Ao ratio is lower in children clinically assessed to be dehydrated. Furthermore, it increases with administration of i.v. fluid boluses.

To describe and compare patients' and nurses' preferences for the implementation of bedside handover. Discrete choice experiment describing handover choices using six characteristics: whether the patient is invited to participate; whether a family member/carer/friend is invited; the number of nurses present; the level of patient involvement; the information content; and privacy. Two Australian hospitals. Adult patients (n=401) and nurses (n=200) recruited from medical wards. Mean importance scores for handover characteristics estimated using mixed multinomial logit regression of the choice data. Both patient and nurse participants preferred handover at the bedside rather than elsewhere (P<.05). Being invited to participate, supporting strong two-way communication, having a family member/carer/friend present and having two nurses rather than the nursing team present were most important for patients. Patients being invited to participate and supporting strong two-way communication were most important for nurses. However, contrary to patient preferences, having a family member/carer/friend present was not considered important by nurses. Further, while patients expressed a weak preference to have sensitive information handed over quietly at the bedside, nurses expressed a relatively strong preference for handover of sensitive information verbally away from the bedside. All participants strongly support handover at the bedside and want patients to participate although patient and nurse preferences for various aspects of bedside handover differ. An understanding of these preferences is expected to support recommendations for improving the patient hospital experience and the consistent implementation of bedside handover as a safety initiative. © 2016 The Authors.

As part of efforts to improve patient safety, quality of care and patient- and family-centred care, there is a growing interest in moving away from traditional taped nursing reports or reporting at the nursing station to reporting at the bedside. Although a body of knowledge exists regarding what nurses view as benefits and challenges experienced in nurse-to-nurse bedside reporting, less is known about the perceptions of nurses who have experienced this change in reporting practice on their unit. In this context, a qualitative study using semi-structured interviews was undertaken to explore nurses' perceptions of a newly implemented nurse-to-nurse bedside reporting practice at one acute care hospital. A total of 43 interviews were conducted on four units with seven nurses from respirology, 10 from obstetrics and gynecology, 10 from nephrology and 16 from general surgery. Data were analyzed using a directed content analysis approach. Three themes emerged that captured nurses' perceptions of the implementation of nurse-to-nurse bedside reporting: (a) being supported to change and embrace bedside reporting, (b) maintaining confidentiality and respecting patients' preferences and (c) experiencing challenges with bedside reporting. Our findings provide insight for other organizations in their efforts to change reporting practices. Specifically, there is a need for multi-pronged initiatives including leadership support, educational opportunities and ongoing monitoring and feedback mechanisms. Future research is required to examine how enablers can be leveraged and barriers mitigated or removed to ensure successful implementation and sustainability of nurse-to-nurse bedside reporting.

Identification of drug interactions in hospitals--computerized screening vs. bedside recording.

PubMed

Blix, H S; Viktil, K K; Moger, T A; Reikvam, A

2008-04-01

Managing drug interactions in hospitalized patients is important and challenging. The objective of the study was to compare two methods for identification of drug interactions (DDIs)--computerized screening and prospective bedside recording--with regard to capability of identifying DDIs. Patient characteristics were recorded for patients admitted to five hospitals. By bedside evaluation drug-related problems, including DDIs, were prospectively recorded by pharmacists and discussed in multidisciplinary teams. A computer screening programme was used to identify DDIs retrospectively--dividing DDIs into four classes: A, avoid; B, avoid/take precautions; C, take precautions; D, no action needed. Among 827 patients, computer screening identified DDIs in 544 patients (66%); 351 had DDIs introduced in hospital. The 1513 computer-identified DDIs had the following distribution: type A 78; type B 915; type C 38; type D 482. By bedside evaluation, 99 DDIs were identified in 73 patients (9%). The proportions of computer recorded DDIs which were also identified at the bedside were: 5%, 8%, 8%, 2% DDIs of types A, B, C and D respectively. In 10 patients, DDIs not registered by computer screening were identified by bedside evaluation. The drugs most frequently involved in DDIs, identified by computerized screening were acetylsalicylic acid, warfarin, furosemide and digitoxin compared with warfarin, simvastatin, theophylline and carbamazepine, by bedside evaluation. Despite an active prospective bedside search for DDIs, this approach identified less than one in 10 of the DDIs recorded by computer screening, including those regarded as hazardous. However, computer screening overestimates considerably when the objective is to identify clinically relevant DDIs.

Development of a hospitalist-led-and-directed physical examination curriculum.

Deficiencies in physical examination skills among medical students, housestaff, and even faculty have been reported for decades, though specifics on how to address this deficit are lacking. Our institution has made a commitment to improving key physical examination competencies across our general medicine faculty. Development of the Merrin Bedside Teaching Program was guided by a comprehensive needs assessment and based on a learner-centered educational model. First, selected faculty fellows achieve expertise through mentorship with a master clinician. They then develop a bedside teaching curriculum in the selected domain and conclude by delivering the curriculum to peer faculty. We have developed curricula in examination of the heart, shoulder, knee, and skin. Currently, curricula are being developed in the examination of the lungs, critical care bedside rounds, and motivational interviewing. Curricula are integrated with educational activities of the internal medicine residency and medical school whenever possible. A hospitalist-led physical examination curriculum is an innovative way to address deficits in physical exam skills at all levels of training, engenders enthusiasm for skills development from faculty and learners, offers scholarship opportunities to general medicine faculty, encourages collaboration within and between institutions, and augments the education of residents and medical students.

While delayed umbilical cord clamping in preterm infants has shown to improve long-term neurological outcomes, infants who are thought to need resuscitation do not receive delayed cord clamping even though they may benefit the most. A mobile resuscitation platform allows infants to be resuscitated at the mother's bedside with the cord intact. The newborn is supplied with placental blood during the resuscitation in view of the mother. The objective of the study is to assess the usability and acceptability of mobile resuscitation platform, LifeStart trolley, among the infants' parents and perinatal providers. A resuscitation platform was present during every delivery that required advanced neonatal providers for high-risk deliveries. Perinatal providers and parents of the infants were given a questionnaire shortly after the delivery. 60 neonatal subjects were placed on the trolley. The majority of deliveries were high risk for meconium-stained amniotic fluid (43%), and non-reassuring fetal heart rate (45%). About 50% of neonatal providers felt that there were some concerns regarding access to the baby. No parents were uncomfortable with the bedside neonatal interventions, and most parents perceived that communication was improved because of the proximity to the care team. Bedside resuscitation with umbilical cord intact through the use of a mobile resuscitation trolley is feasible, safe, and effective, but about half of the perinatal providers expressed concerns. Logistical issues such as improved space management and/or delivery setup should be considered in centers planning to perform neonatal resuscitation with an intact cord.

Background: falls in hospitals are a major problem and contribute to substantial healthcare burden. Advances in sensor technology afford innovative approaches to reducing falls in acute hospital care. However, whether these are clinically effective and cost effective in the UK setting has not been evaluated. Methods: pragmatic, parallel-arm, individual randomised controlled trial of bed and bedside chair pressure sensors using radio-pagers (intervention group) compared with standard care (control group) in elderly patients admitted to acute, general medical wards, in a large UK teaching hospital. Primary outcome measure number of in-patient bedside falls per 1,000 bed days. Results: 1,839 participants were randomised (918 to the intervention group and 921 to the control group). There were 85 bedside falls (65 fallers) in the intervention group, falls rate 8.71 per 1,000 bed days compared with 83 bedside falls (64 fallers) in the control group, falls rate 9.84 per 1,000 bed days (adjusted incidence rate ratio, 0.90; 95% confidence interval [CI], 0.66–1.22; P = 0.51). There was no significant difference between the two groups with respect to time to first bedside fall (adjusted hazard ratio (HR), 0.95; 95% CI: 0.67–1.34; P= 0.12). The mean cost per patient in the intervention group was £7199 compared with £6400 in the control group, mean difference in QALYs per patient, 0.0001 (95% CI: −0.0006–0.0004, P= 0.67). Conclusions: bed and bedside chair pressure sensors as a single intervention strategy do not reduce in-patient bedside falls, time to first bedside fall and are not cost-effective in elderly patients in acute, general medical wards in the UK.

The ultimate goal of therapeutic strategies for ischemic stroke is to reestablish the blood flow to the ischemic region of the brain. However, currently, the local cerebral hemodynamics (microvascular) is almost entirely inaccessible for stroke clinicians at the patient bed-side, and the recanalization of the major cerebral arteries (macrovascular) is the only available measure to evaluate the therapy, which does not always reflect the local conditions. Here we report the case of an ischemic stroke patient whose microvascular cerebral blood flow and oxygenation were monitored by a compact hybrid diffuse optical monitor during thrombolytic therapy. This monitor combined diffuse correlation spectroscopy and near-infrared spectroscopy. The reperfusion assessed by hybrid diffuse optics temporally correlated with the recanalization of the middle cerebral artery (assessed by transcranial-Doppler) and was in agreement with the patient outcome. This study suggests that upon further investigation, diffuse optics might have a potential for bed-side acute stroke monitoring and therapy guidance by providing hemodynamics information at the microvascular level.

Intravenous iron is commonly administered to anaemic patients to treat iron deficiency, but due to its ferric colouration, it may interfere with the spectrophotometric assessment of haemoglobin concentrations. This paper investigates the potential interference of three clinically used intravenous iron preparations on the measurement of haemoglobin. Haemoglobin concentration was measured for neat and Hartmann's solution-diluted iron polymaltose, carboxymaltose and sucrose solutions using bedside (Radiometer HemoCue®), point-of-care (Radiometer ABL800 Flex) and laboratory (Abbott CellDyne Sapphire™) devices. Haemoglobin concentration was then assessed with the same devices utilizing anaemic whole blood with the iron solutions added. Neat iron preparations registered clinically significant haemoglobin concentrations on bedside and laboratory measurements. When intravenous iron preparations were diluted to clinical concentrations, their effect on haemoglobin measurements, either in isolation or mixed with anaemic blood, was negligible. Although neat preparations of intravenous iron do interfere with spectrophotometric analysis of haemoglobin, concentrations likely to be seen post iron infusion do not significantly interfere with haemoglobin measurement. © The Author(s) 2015.

Bedside teaching is recognised as a valuable tool in medical education by both students and faculty members. Bedside teaching is frequently delivered by consultants; however, junior doctors are increasingly engaging in this form of clinical teaching, and their value in this respect is becoming more widely recognised. The aim of this study was to supplement work completed by previous authors who have begun to explore students' satisfaction with bedside teaching, and their perceptions of the relationship with the clinical teachers. Specifically, we aimed to identify how students perceive bedside teaching delivered by junior doctors compared with consultants. We aimed to identify how students perceived bedside teaching delivered by junior doctors compared with consultants METHODS: A questionnaire was distributed to all third-year medical students at Keele University via e-mail. Responses were submitted anonymously. Forty-six students responded (37.4%), 73.3 per cent of whom said that they felt more comfortable having bedside teaching delivered by junior doctors than by consultants. Consultants were perceived as more challenging by 60 per cent of respondents. Students appeared to value feedback on their performance, trust the validity of taught information, and to value the overall educational experience equally, regardless of the clinical grade of the teacher. Student preference does not equate to the value that they place on their bedside teaching. Junior doctors are perceived as being more in touch with students and the curriculum, whereas consultants are perceived as having higher expectations and as being both stricter and more knowledgeable. The clinical teacher's approachable manner and enthusiasm for teaching are more important than clinical grade, as is the ability to deliver well-structured constructive feedback. © 2016 John Wiley & Sons Ltd.

To evaluate the feasibility, appropriateness, meaningfulness and effectiveness of bedside shift reporting in a minimum of five interventions and five control wards. Hospitals continually improve their quality of care. Next to improvements in clinical performance, more patient participation is stimulated through different methods. Methods to enhance patient participation such as bedside shift reporting lack rigorously performed research to determine their feasibility, appropriateness, meaningfulness and effectiveness. Small-scale research and a previous pilot study indicate that bedside shift reporting improves patient participation, nurse-nurse communication and nurse-patient communication. The development, implementation and evaluation of bedside shift report are based on the Medical Research Council framework for complex interventions in health care. A matched, controlled, mixed-method, longitudinal study design will be used. The Feasibility-Appropriateness-Meaningfulness-Effectiveness framework will be applied for the quantitative and qualitative evaluation of bedside shift report. A tailored intervention and implementation process for bedside shift report will be developed using diagnostic interviews, co-design and acceptability testing. The intervention will be evaluated before implementation and three times after implementation. Individual and focus group interviews will be performed. Questionnaires, observations and analysis of the medical records and administrative databases will be completed. This study was funded in October 2015. Research Ethics Committee approval was granted in March 2016. There is a pressing need for rigorous research into the effects of interventions for improving patient participation. This study addresses the significance of bedside shift report as an intervention to improve quality of care, communication and patient participation within a large-scale, matched, controlled research design. © 2016 John Wiley & Sons Ltd.

The economic crisis, the growing healthcare demand, and Defensive Medicine wastefulness, strongly recommend the restructuring of the entire medical network. New health technology, such as bedside ultrasonography, might successfully integrate the clinical approach optimizing the use of limited resources, especially in a person-oriented vision of medicine. Bedside ultrasonography is a safe and reliable technique, with worldwide expanding employment in various clinical settings, being considered as "the stethoscope of the 21st century". However, at present, bedside ultrasonography lacks economic analysis. We performed a Cost-Benefit Analysis "ex ante", with a break-even point computing, of bedside ultrasonography implementation in an Internal Medicine department in the mid-term. Number and kind estimation of bedside ultrasonographic studies were obtained by a retrospective study, whose data results were applied to the next 3-year period (foresight study). All 1980 foreseen bedside examinations, with prevailing multiorgan ultrasonographic studies, were considered to calculate direct and indirect costs, while specific and generic revenues were considered only after the first semester. Physician professional training, equipment purchase and working time represented the main fixed and variable cost items. DRG increase/appropriateness, hospitalization stay shortening and reduction of traditional ultrasonography examination requests mainly impacted on calculated revenues. The break-even point, i.e. the volume of activity at which revenues exactly equal total incurred costs, was calculated to be 734 US examinations, corresponding to € 81,998 and the time considered necessary to reach it resulting 406 days. Our economic analysis clearly shows that bedside ultrasonography implementation in clinical daily management of an Internal Medicine department can produce consistent savings, or economic profit according to managerial choices (i.e., considering public or private targets), other than evident medical benefits.

Patient participation in bedside reporting on surgical wards.

Increasingly nowadays, patients have an opportunity to take part in nurses' reporting sessions via bedside reporting. The aim of this study was to compare nurses' and patients' opinions of the purpose of bedside reports, patient participation in bedside reporting sessions, and factors that promote or prevent their participation. Data were collected by a questionnaire survey of nurses (N = 118) and patients (N = 74). A response rate of 81% was achieved in both groups. Additionally, 76 bedside reporting sessions were observed. According to patients, the main reasons for not participating were tiredness, difficulties in formulating questions, lack of encouragement, difficulties with the language used, nurses concentrating more on their papers than on them, and the reporting sessions were too short. Nurses reported that patients took a more active part in reporting sessions than patients themselves thought. The average time spent on each patient's report was three minutes.

Bedside teaching with unwell patients: Can it ever be appropriate?

PubMed

Jayakumar, Nithish

2017-03-01

Bedside teaching has seen a decline in its popularity since the heady days of Boerhaave and Osler; a number of hurdles have been noted in the literature including time constraints on senior clinicians. While organizing a bedside teaching course for final-year medical students, it was apparent that the availability of suitable patients was also a limiting factor. Often, we would be turned away from patients with physical signs because they were deemed to be too unwell for an examination. However, the benefits to medical students of examining unwell patients with physical signs cannot be underestimated. Identifying the unwell patient, and the associated physical signs relevant to the underlying diagnosis, should be a priority; although simulation is increasingly being used in teaching, it cannot fully replicate the learning experience gained in bedside teaching. As long as the patient is not under duress, bedside teaching with unwell patients should be encouraged.

Time to Add a Fifth Pillar to Bedside Physical Examination: Inspection, Palpation, Percussion, Auscultation, and Insonation.

PubMed

Narula, Jagat; Chandrashekhar, Y; Braunwald, Eugene

2018-04-01

Inspection, palpation, percussion, and auscultation have been the 4 pillars of clinical bedside medicine. Although these basic methods of physical examination have served us well, traditional bedside examination, for a number of reasons including diminishing interest and expertise, performs well less than what is required of a modern diagnostic strategy. Improving the performance of physical examination is vital given that it is crucial to guide diagnostic possibilities and further testing. Current efforts at improving physical examination skills during medical training have not been very successful, and incorporating appropriate technology at the bedside might improve its performance. Selective use of bedside ultrasound (or insonation) can be one such strategy that could be incorporated as the fifth component of the physical examination. Seeing pathology through imaging might improve interest in physical examination among trainees, and permit appropriate downstream testing and possibly superior decision making. Current ultrasound technology makes this feasible, and further miniaturization of ultrasound devices and reduced cost will allow for routine use at the bedside. It is time to have a wider debate and a possible consensus about updates required to enhance current paradigms of physical examination.

To determine the percentage of time that critically ill children have a parent at the bedside and to identify extrinsic factors that are associated with percent of time with parental presence at the bedside. Prospective cohort study. PICU in a single tertiary care children's hospital. Primary two parents of all children admitted to the PICU on 12 preselected days during a 1-year period from 2014 to 2015. None. A total of 111 observations of 108 unique PICU admissions and families were performed. Children had at least one parent present a mean of 58.2% (SD, 34.6%) of the time. Mothers spent more time at the bedside (56.3% [SD, 31.0%]) than fathers (37.3% [SD, 29.5%]) (p = 0.0001). Percent of time with parental presence at the bedside was positively correlated with age (rs = 0.23; p = 0.02) and negatively associated with Pediatric Risk of Mortality III score (rs = -0.26; p = 0.01). Percent of time with parental presence at the bedside was lower for children who were mechanically ventilated (42.8% [SD, 35.5%]) than not (64.5% [SD, 32.2%]) (p = 0.01) and whose parent(s) were single (45.5% [SD, 27.5%]) or cohabitating/common-law (35.7% [SD, 26.4%]) compared with parents who were married (64.2% [SD, 34.2%]) or separated/divorced (68.3% [SD, 28.8%]) (p = 0.02). Percent of time with parental presence at the bedside was higher for children with chronic illnesses (63.4% [SD, 32.9%] vs 50.1% [SD, 35.8%] without; p = 0.04), when there was a bed in the patient room (61.4% [SD, 34.0%] vs 32.5% [SD, 28.3%] without; p = 0.01), and when parents slept in the patient room (90.3% [SD, 11.2%]) compared with their own home (37.6% [SD, 34.4%]) (p < 0.0001). Percent of time with parental presence at the bedside was not correlated with day of PICU stay, number of siblings, previous PICU admission, isolation status, or nursing ratio. Children had a parent present at the bedside approximately 60% of the time. The parents of younger, sicker children may benefit from supportive interventions during PICU admission. Further research is needed to examine both extrinsic and intrinsic factors affecting parental presence at the bedside.

Background: Bedside courses are of outstanding importance when training medical students. The fact that less and less teaching is taking place nowadays at the patient's bedside makes it all the more important that the available time be put to effective use. The aim of this study was to check whether structured improvement measures in the course (scripts, lecturer briefing, e-learning cases) would improve the abilities of the students on the basis of a subjective self-assessment as well as an external assessment by the lecturers with respect to clinical abilities. Methods: Bedside teaching takes place in the fourth study year in the Medical Clinics of the TU Munich. Both students and lecturers had the chance to hand in an anonymous, quantitative self- and external assessment of the clinical abilities of the students (German grading system) after every course date. This assessment took place online in the three categories "Medical history & examination", "Diagnosis" and "Therapy". An overall period of four semesters, each with 6 course dates, was investigated. After two of the total of four semesters in the study, the course was changed by introducing scripts, lecturer briefing as well as interactive e-learning cases. The self- and external assessment was compared both within the semester (date 1-3: A; date 4-6: B), during the course as well as before and after introducing the improvement measures ("before" (T0): SS 2012, SS 2013, "after" (T1): WS 2013/2014, SS 2014). Results: There was a significant improvement in one's own abilities on the basis of the self-assessment within each semester when comparing the first (A) and the last (B) course dates. Moreover, there was a significant improvement in the performances in all three categories when T0 was compared with T1, from both the point of view of the students ("Medical history & examination": T0 =2.5±0.9, T1=2.2±0.7, pp<0.001; "Diagnosis" T0=3.1±1.0, T1=2.8 ±0.9, pp<0.001; "Therapy": T0=3.8±1.3, T1=3.5±1.2, pp<0.018) and in two of the three categories from the point of view of the lecturers ("Diagnosis": T0=3.0±1.0, T1=2.7±0.7, p.=0.028; "Therapy": T0=3.8±1.1, T1=3.1±1.0, p<0.001). Summary: The structured measures to improve the course including the interactive e-learning cases could have contributed to improved practical abilities with respect to the medical history and examination techniques as well as diagnostic and therapeutic thinking. The external evaluation by lecturers confirmed the improvement with respect to the diagnostic and therapeutic abilities. They only saw no dynamic change in the student's taking histories and clinical examinations. PMID:27579359

Bedside Treatment of Chronic Subdural Hematoma: Using Radiographic Characteristics to Revisit the Twist Drill.

Conventional treatment strategies for the management of symptomatic chronic subdural hematoma (cSDH) in the elderly include observation, operative burr holes or craniotomy, and bedside twist drill drainage. The decision on which technique to use should be determined by weighing the comorbidities and symptoms of the patient with the potential risks and benefits. The goal of this study was to identify radiographic characteristics on computed tomography scan that might be used to guide surgical decision making in terms of operative versus bedside removal of cSDH. We retrospectively reviewed clinical and radiographic features in patients who underwent bedside twist drill evacuation of a cSDH and those for a cohort of patients who underwent operative intervention via burr holes. We did not identify any clinical features or preoperative imaging characteristics to suggest an advantage of one procedure over the other. Additionally, complete radiographic resolution of cSDH on postoperative imaging is not required to relieve patient symptoms. Although bedside twist drill evacuation may avoid operating room costs and anesthetic complications in an elderly patient population and allow earlier resumption of anticoagulation treatment if necessary, there is also a risk of morbidity if uncontrolled bleeding is encountered or the patient is unable to tolerate the bedside procedure. However, bedside twist drill craniostomy is a reasonable and effective option for the treatment of subacute/chronic SDH in patients who may not be optimal surgical candidates.

[Yes, we should keep ABO agglutination test within bedside transfusion checks].

Daurat, G

2008-11-01

ABO incompatible transfusions are still a frequent cause of serious adverse transfusion reactions. Bedside check is intended to detect patient errors and prevent ABO mismatch. France is one of the few countries that includes ABO agglutination test for red blood cells in bedside checks. Evaluation of this ABO agglutination test, performed with a special card, shows that, on the field, despite frequent users' mishandling, it can detect up to 93% of ABO incompatibilities. This is not enough to rely on this sole test for bedside checks. But, linking it with an another test, currently, checks that the right blood is given to the right patient, rises the sensitivity of the whole bedside procedure up to an estimated 99.65%, for detection of ABO incompatibilities. This linkage has been introduced in the French regulation in 2003. Since then, the incidence of ABO incompatible transfusions has decreased dramatically and faster than in any other country, so France has now, probably, the lowest rate of ABO incompatible transfusions. The investigation of the few ABO accidents that still occur, shows that professionals have always bypassed this linkage. On the other hand, introducing bedside recipient and blood products barcode or radio-chip checks in all the 1500 French hospitals, though technically possible, would provide very little enhancement and lead to major difficulties and expenses. Linkage of ABO agglutination test to patient and blood checks within the bedside procedure has proved to be efficient and should be kept.

To examine the diagnostic accuracy of a two-stage clinical decision support system for early recognition and stratification of patients with sepsis. Observational cohort study employing a two-stage sepsis clinical decision support to recognise and stratify patients with sepsis. The stage one component was comprised of a cloud-based clinical decision support with 24/7 surveillance to detect patients at risk of sepsis. The cloud-based clinical decision support delivered notifications to the patients' designated nurse, who then electronically contacted a provider. The second stage component comprised a sepsis screening and stratification form integrated into the patient electronic health record, essentially an evidence-based decision aid, used by providers to assess patients at bedside. Urban, 284 acute bed community hospital in the USA; 16,000 hospitalisations annually. Data on 2620 adult patients were collected retrospectively in 2014 after the clinical decision support was implemented. 'Suspected infection' was the established gold standard to assess clinical decision support clinimetric performance. A sepsis alert activated on 417 (16%) of 2620 adult patients hospitalised. Applying 'suspected infection' as standard, the patient population characteristics showed 72% sensitivity and 73% positive predictive value. A postalert screening conducted by providers at bedside of 417 patients achieved 81% sensitivity and 94% positive predictive value. Providers documented against 89% patients with an alert activated by clinical decision support and completed 75% of bedside screening and stratification of patients with sepsis within one hour from notification. A clinical decision support binary alarm system with cross-checking functionality improves early recognition and facilitates stratification of patients with sepsis.

Learner benefits of tablet computer use have been demonstrated, yet there is little evidence regarding faculty tablet use for teaching. Our study sought to determine if supplying faculty with tablet computers and peer mentoring provided benefits to learners and faculty beyond that of non-tablet-based teaching modalities. We provided faculty with tablet computers and three 2-hour peer-mentoring workshops on tablet-based teaching. Faculty used tablets to teach, in addition to their current, non-tablet-based methods. Presurveys, postsurveys, and monthly faculty surveys assessed feasibility, utilization, and comparisons to current modalities. Learner surveys assessed perceived effectiveness and comparisons to current modalities. All feedback received from open-ended questions was reviewed by the authors and organized into categories. Of 15 eligible faculty, 14 participated. Each participant attended at least 2 of the 3 workshops, with 10 to 12 participants at each workshop. All participants found the workshops useful, and reported that the new tablet-based teaching modality added value beyond that of current teaching methods. Respondents developed the following tablet-based outputs: presentations, photo galleries, evaluation tools, and online modules. Of the outputs, 60% were used in the ambulatory clinics, 33% in intensive care unit bedside teaching rounds, and 7% in inpatient medical unit bedside teaching rounds. Learners reported that common benefits of tablet computers were: improved access/convenience (41%), improved interactive learning (38%), and improved bedside teaching and patient care (13%). A common barrier faculty identified was inconsistent wireless access (14%), while no barriers were identified by the majority of learners. Providing faculty with tablet computers and having peer-mentoring workshops to discuss their use was feasible and added value.

Ascites remains the most common cause of hospitalization among patients with decompensated cirrhosis. Paracentesis is a relatively safe procedure with low complication rates. Computerized tomography (CT)-guided therapeutic paracentesis could be a safe and effective alternative to unaided or aided (ultrasonogram-guided) bedside paracentesis. In this retrospective study, we aimed to compare the efficacy, safety, and cost-effectiveness of CT-guided paracentesis with bedside paracentesis. The period of study was from 2002 to 2012. All patients with cirrhosis who underwent therapeutic paracentesis were included in the study. These patients were divided into two groups. Group I consisted of patients who underwent CT-guided pigtail catheter insertion with ascitic fluid drainage. Group II consisted of patients who underwent beside therapeutic paracentesis after localization of fluid either by physical examination or sonographic localization. We measured the efficacy of CT-guided paracentesis and bedside paracentesis in terms of volume of fluid removed, length of stay, discharge doses of diuretics (spironolactone and furosemide) and number of days to readmission for symptomatic ascites. We also computed the cost-effectiveness of CT-guided therapeutic paracentesis when compared to a bedside procedure. Fischer exact test was used to analyze the distribution of categorical data and unpaired t -test was used for comparison of means. There were a total of 546 unique patients with diagnosed cirrhosis who were admitted to the hospital with symptomatic ascites and underwent therapeutic paracentesis. Two hundred and forty-seven patients underwent CT-guided paracentesis, while 272 patients underwent bedside paracentesis. There was significant inverse correlation between the amount of ascitic fluid removed and total length of stay in the hospital. We found that the volume of fluid removed via a CT-guided pigtail insertion and drainage (2.72 ± 2.02 L) is significantly higher when compared to fluid removed via bedside paracentesis (1.94 ± 1.69). We also found that the interval time period between two successive therapeutic paracenteses was significantly longer for CT group (106.56 ± 75.2 days) when compared to the bedside group (25.57 ± 7.68 days). CT-guided paracentesis with pigtail catheter insertion and drainage is a clinically effective, cheap and safe alternative to conventional bedside paracentesis.

Prospectively identifying children with significant dehydration from gastroenteritis is difficult in acute care settings. Previous work by our group has shown that bedside ultrasound (US) measurement of the inferior vena cava (IVC) and the aorta (Ao) diameter ratio is correlated with intravascular volume. This study was designed to validate the use of this method in the prospective identification of children with dehydration by investigating whether the IVC/Ao ratio correlated with dehydration in children with acute gastroenteritis. Another objective was to investigate the interrater reliability of the IVC/Ao measurements. A prospective observational study was carried out in a pediatric emergency department (PED) between November 2007 and June 2009. Children with acute gastroenteritis were enrolled as subjects. A pair of investigators obtained transverse images of the IVC and Ao using bedside US. The ratio of IVC and Ao diameters (IVC/Ao) was calculated. Subjects were asked to return after resolution of symptoms. The difference between the convalescent weight and ill weight was used to calculate the degree of dehydration. Greater than or equal to 5% difference was judged to be significant. Linear regression was performed with dehydration as the dependent variable and the IVC/Ao as the independent variable. Pearson's correlation coefficient was calculated to assess the degree of agreement between observers. A total of 112 subjects were enrolled. Seventy-one subjects (63%) completed follow-up. Twenty-eight subjects (39%) had significant dehydration. The linear regression model resulted in an R² value of 0.21 (p < 0.001) and a slope (B) of 0.11 (95% confidence interval [CI] = 0.08 to 0.14). An IVC/Ao cutoff of 0.8 produced a sensitivity of 86% and a specificity of 56% for the diagnosis of significant dehydration. Forty-eight paired measurements of IVC/Ao ratios were made. The Pearson correlation coefficient was 0.76.   In this pilot study the ratio of IVC to Ao diameters, as measured by bedside US, was a marginally accurate measurement of acute weight loss in children with dehydration from gastroenteritis. The technique demonstrated good interrater reliability. © 2010 by the Society for Academic Emergency Medicine.

Extracorporeal membrane oxygenation (ECMO) is a lifesaving but expensive therapy in terms of financial, technical and human resources. We report our experience with a 'basic' ECMO support model, consisting of ECMO initiated and managed without the constant presence of a bedside specialist, to assess safety, clinical outcomes and financial impact on our health system. We did a retrospective single-centre study of paediatric cardiac ECMO between January 2001 and March 2014. Outcomes included postimplant complications and survival at weaning and at discharge. We used activity based costing to compare the costs of current basic ECMO with those of a 'full optional' dedicated ECMO team (hypothesis 1); ECMO with a bedside nurse and perfusionist (hypothesis 2), and ECMO with a bedside perfusionist (hypothesis 3). Basic cardiac ECMO was required for 121 patients (median age 75 days, median weight 4.4 kg). A total of 107 patients (88%) had congenital heart disease; 37 had univentricular physiology. The median duration of ECMO was 7 days (interquartile range [IQR], 4-15 days). Overall survival at weaning and at 30 days in the neonatal and paediatric age groups was 58.6% and 30.6%, respectively; these results were not significantly different from Extracorporeal Life Support Organization data. Cost analysis revealed a saving of €30 366, €22 144 and €13 837 for each patient on basic ECMO for hypotheses 1, 2 and 3, respectively. Despite reduced human, technical and economical resources, a basic ECMO model without a bedside specialist was associated with satisfactory survival and lower costs. © The Author 2017.

The worldwide demand for ECMO support has grown. Its provision remains limited due to several factors (high cost, complicated technology, lack of expertise) that increase healthcare cost. Our goal was to assess if an intensive care unit (ICU)-run ECMO model without continuous bedside perfusionists would decrease costs while maintaining patient safety and outcomes. A new ECMO program was implemented in 2010, consisting of dedicated ICU multidisciplinary providers (ICU-registered nurses, mid-level providers and intensivists). In year one, we introduced an education platform, new technology and dedicated space. In year two, continuous bedside monitoring by perfusionists was removed and new management algorithms designating multidisciplinary providers as first responders were established. The patient safety and cost benefit from the removal of the continuous bedside monitoring of the perfusionists of this new ECMO program was retrospectively reviewed and compared. During the study period, 74 patients (28 patients in year 1 and 46 patients in year 2) were placed on ECMO (mean days: 8 ± 5.7). The total annual hospital expenditure for the ECMO program was significantly reduced in the new model ($234,000 in year 2 vs. $600,264 in year 1), showing a 61% decrease in cost. This cost decrease was attributed to a decreased utilization of perfusion services and the introduction of longer lasting and more efficient ECMO technology. We did not find any significant changes in registered nurse ratios or any differences in outcomes related to ICU safety events. We demonstrated that the ICU-run ECMO model managed to lower hospital cost by reducing the cost of continuous bedside perfusion support without a change in outcomes. © The Author(s) 2014.

Standardized handoffs may reduce communication errors, but research on handoff in community and international settings is lacking. Our study at a community hospital in the United Arab Emirates characterizes existing handoff practices for admitted patients from emergency medicine (EM) to internal medicine (IM), develops a standardized handoff tool, and assesses its impact on communication and physician perceptions. EM physicians completed a survey regarding handoff practices and expectations. Trained observers utilized a checklist based on the Systems Engineering Initiative for Patient Safety model to observe 40 handoffs. EM and IM physicians collaboratively developed a written tool encouraging bedside handoff of admitted patients. After the intervention, surveys of EM physicians and 40 observations were subsequently repeated. 77.5% of initial observed handoffs occurred face-to-face, with 42.5% at bedside, and in four different languages. Most survey respondents considered face-to-face handoff ideal. Respondents noted 9-13 patients suffering harm due to handoff in the prior month. After handoff tool implementation, 97.5% of observed handoffs occurred face-to-face (versus 77.5%, p = 0.014), with 82.5% at bedside (versus 42.5%, p < 0.001), and all in English. Handoff was streamlined from 7 possible pathways to 3. Most post-intervention survey respondents reported improved workflow (77.8%) and safety (83.3%); none reported patient harm. Respondents and observers noted reduced inefficiency (p < 0.05). Our standardized tool increased face-to-face and bedside handoff, positively impacted workflow, and increased perceptions of safety by EM physicians in an international, non-academic setting. Our three-step approach can be applied towards developing standardized, context-specific inter-specialty handoff in a variety of settings.

Bedside stations, also known as bedside terminals, are in place to enhance the quality and experience of a hospital's healthcare service delivery. The purpose of this study was to identify information needs and overall satisfaction with the personalized patient bedside system, called Smart Bedside Station (SBS) system, embedded in a tertiary general university hospital. End-user responses on the satisfaction survey and system usage logs of the SBS system were collected and analyzed. For the user opinion survey, 156 nurses and 1914 patients, their family members, or caregivers participated during the evaluation period of 2013 to 2014 in this study. All working nurses in the SBS-installed ward were answered the paper-based evaluation, for complete enumeration survey. Inpatients were voluntary participated to deliver the online questionnaire on the SBS menu. We also explored system log data including page calls and usage time from December 2013 to 2015. Regarding the relationship of overall satisfaction of the SBS with patient's characteristics, patient's education status and degree of familiarity with the smart device were statistically significant. From the analysis of system logs, Personalized My Menu(28.0%) was the most frequently used menu item (except for TV and Internet entertainment service use of 62.7%),it provides individual health information, such as laboratory test results, hospital fee check, message logs, daily medication information, and meal information. Next frequently used menus were information support(4.9%) which deliver hospital guide and health information and convenience service ordering(4.4%) such as meal order, bed sheet change. Satisfaction survey results and log data results show that the personalized service enhances the user satisfaction during hospital admission. Our post-implementation experience and subsequent assessment of SBS system is capable of providing insights into improving the hospital information system and service contents for patient-centered services. Further research should be directed at developing sophisticated patient-centered services as a communication tool between the hospital and the patient. Copyright © 2016 Elsevier Ireland Ltd.

Grimshaw, John; Hatch, Daniel; Willard, Melissa; Abraham, Sam

Concerns about patient bedside change-of-shift reporting at a community hospital in northern Indiana stimulated the development of this qualitative phenomenological study. A review of the literature revealed a research deficit in acute care nurses' perceptions of bedside reporting in relation to compliance. The research question addressed in this study was, "What are acute care nurses' perceptions of the change-of-shift report at the patients' bedside?" Personal interviews were conducted on 7 medical, surgical, and intensive care unit nurse participants at a community hospital in northern Indiana. Five themes were identified from the collected data, which included the time factor, continuity of care, visualization, and challenges in the communication of discreet information.

Right to know: reducing risks of fecal pathogen exposure for ED patients and staff.

PubMed

Delaney, Molly Bridget

2014-07-01

The purpose of this article is to review the literature regarding the multiple challenges that contribute to ED bedside toileting and examine best practices that will reduce fecal exposure, cross-contamination among patients, and employee splash injuries. We searched the Cumulative Index to Nursing and Allied Health Literature, MEDLINE, and Cochrane database for information about the multiple challenges involved in bedside toileting, using the following search terms: bedside toileting, gastroenteritis, macerator, sluice machine, fecal pathogen exposure, and splash injury. In addition, costs and benefits of reusable versus disposable bedside toileting equipment were compared and contrasted. Emergency departments have a higher exposure rate to fecal pathogens with current methods of bedside toileting. Short incubation periods may not allow the proper lead time needed for patients to access primary care providers. As a result, emergency departments and urgent care centers become a likely point of entry into the health care system. Although most inpatient rooms have built-in bathrooms, most emergency departments and outpatient examination rooms do not. Although many patients are ambulatory, restrictive monitoring equipment is required. For safety reasons, staff must bring toileting equipment to the bedsides of both ambulatory and non-ambulatory patients. Hopper dependence creates longer walking distances and delays. These delays may lead to incontinence events, skin breakdown, more frequent bed changes, and higher linen and labor costs. Reusable bedside toileting equipment is associated with at-risk behaviors. Examples are procrastination and sanitization shortcuts. These behaviors risk cross-contamination of patients especially when urgent situations require equipment to be reused in the interim. ED patients and staff are 5 times more likely to undergo fecal exposure. The 5 phases of ED bedside toileting at which risks occur are as follows: equipment setup, transport of human waste to drainage areas, transfer of waste, pre-cleaning, and equipment disinfection. Therefore it is imperative that ED staff have a full understanding of hazardous materials involved, know safer bedside toileting practices, and have safer equipment available to protect all involved. Upgrading our knowledge, equipment, and practices must become a higher priority for ED leadership. The East Bank Emergency Department of the University of Minnesota Medical Center, Fairview, will be moving toward 100% disposable bedside commode pails in addition to disposable bedpans, currently in use. On the basis of a literature review to understand best-practice ED bedside toileting, the following article was created. As a result of our learning, the University of Minnesota Medical Center emergency staff has designed, patented, and developed a landfill-compliant disposable commode pail that absorbs waste while reducing splashes and spills. Disposable commode pails (bags) are conveniently wall mounted for quick availability, and "at-risk behavior" is reduced. Advantages are all point-of-care. Both setup and waste treatment and disposal start and end at the bedside. The advantages are faster response times, reduction of soiled linens and bed changes, prevention of incontinence and skin breakdown events, and reduced splash injuries or pathogen transmission. Patient satisfaction improves with shorter bedside toileting delays. Employee satisfaction increases with reduced human waste handling. The cost of each unit is comparable to an adult overnight diaper. Bariatric commode pails or bags are in the planning phase, and a "green" disposable commode pail, made from biodegradable corn byproducts, will be made available at a higher cost.

Bedside training for fourth-year students, as well as seminars in hospital pharmacy (vital sign seminars) for fifth-year students at the Department of Pharmacy of Kyushu University of Health and Welfare have been implemented using patient training models and various patient simulators. The introduction of simulation-based pharmaceutical education, where no patients are present, promotes visually, aurally, and tactilely simulated learning regarding the evaluation of vital signs and implementation of physical assessment when disease symptoms are present or adverse effects occur. A patient simulator also promotes the creation of training programs for emergency and critical care, with which basic as well as advanced life support can be practiced. In addition, an advanced objective structured clinical examination (OSCE) trial has been implemented to evaluate skills regarding vital signs and physical assessments. Pharmacists are required to examine vital signs and conduct physical assessment from a pharmaceutical point of view. The introduction of these pharmacy clinical skills will improve the efficacy of drugs, work for the prevention or early detection of adverse effects, and promote the appropriate use of drugs. It is considered that simulation-based pharmaceutical education is essential to understand physical assessment, and such education will ideally be applied and developed according to on-site practices.

Dysphagia, aspiration, and potential pneumonia represent a major source of morbidity in patients undergoing lung transplantation. Conditions that potentiate dysphagia and aspiration include frailty and prolonged intubation. Our group of speech-language pathologists has been actively involved in performance of a bedside evaluation of swallowing, and instrumental evaluation of swallowing with modified barium swallow, and postoperative management in patients undergoing lung transplantation. All lung transplant patients from April 2009 to September 2012 were evaluated retrospectively. A clinical bedside examination was performed by the speech-language pathology team, followed by a modified barium swallow or fiberoptic endoscopic evaluation of swallowing. A total of 321 patients were referred for evaluation. Twenty-four patients were unable to complete the evaluation. Clinical signs of aspiration were apparent in 160 patients (54%). Deep laryngeal penetration or aspiration were identified in 198 (67%) patients during instrumental testing. A group of 81 patients (27%) had an entirely normal clinical examination, but were found to have either deep penetration or aspiration. The majority of patients aspirate after lung transplantation. Clinical bedside examination is not sensitive enough and will fail to identify patients with silent aspiration. A standard of practice following lung transplantation has been established that helps avoid postoperative aspiration associated with complications. Copyright © 2017 The Society of Thoracic Surgeons.

We present results of a clinical study on bedside perfusion monitoring of the human brain by optical bolus tracking. We measure the kinetics of the contrast agent indocyanine green using time-domain near-IR spectroscopy (tdNIRS) in 10 patients suffering from acute unilateral ischemic stroke. In all patients, a delay of the bolus over the affected when compared to the unaffected hemisphere is found (mean: 1.5 s, range: 0.2 s to 5.2 s). A portable time-domain near-IR reflectometer is optimized and approved for clinical studies. Data analysis based on statistical moments of time-of-flight distributions of diffusely reflected photons enables high sensitivity to intracerebral changes in bolus kinetics. Since the second centralized moment, variance, is preferentially sensitive to deep absorption changes, it provides a suitable representation of the cerebral signals relevant for perfusion monitoring in stroke. We show that variance-based bolus tracking is also less susceptible to motion artifacts, which often occur in severely affected patients. We present data that clearly manifest the applicability of the tdNIRS approach to assess cerebral perfusion in acute stroke patients at the bedside. This may be of high relevance to its introduction as a monitoring tool on stroke units.

Nurse shift report: who says you can't talk in front of the patient?

PubMed

Anderson, Cherri D; Mangino, Ruthie R

Bedside nurse shift report is a process where nurses provide shift-to-shift report at the patient's bedside so the patient can be more involved in his or her care. There are many benefits of bedside report, including relationship building between staff members and increased patient satisfaction, to both the patient and to the healthcare team. Concerns about the traditional methods of communication between the various shifts helped drive a nursing unit's decision to move to a more patient-involved model of shift-to-shift report. The change from the traditional taped report between healthcare providers to bedside reporting focused on patients wanting more involvement in their care, activities, and current status. Patients also wanted updates about their health status, their medical plan as well as information about their progress toward their goals. This, coupled with Banner Desert Medical Center's Care Model, embraces patient-centered care, King's Theory of Goal Attainment, and keeps the patient informed. The current nursing shift report did not meet the medical center's model of care on any of these aspects. This article will include information on the benefits of bedside nurse shift-to-shift report, how one unit implemented bedside reporting, and some of the outcomes achieved after implementing this change at a 600-bed urban medical center.

Providing newborn resuscitation at the mother’s bedside: assessing the safety, usability and acceptability of a mobile trolley

PubMed Central

2014-01-01

Background Deferring cord clamping at very preterm births may be beneficial for babies. However, deferring cord clamping should not mean that newborn resuscitation is deferred. Providing initial care at birth at the mother’s bedside would allow parents to be present during resuscitation, and would potentially allow initial care to be given with the cord intact. The aim of this study was to evaluate the usability of a new mobile trolley for providing newborn resuscitation by describing the range of resuscitation procedures performed on a group of babies, to assess the acceptability to clinicians compared with standard equipment, based on a questionnaire survey, to assess safety from post resuscitation temperature measurements and serious adverse event reports and to assess whether the trolley allowed resuscitation with the umbilical cord intact by assessing the proportion of babies that could be placed on the trolley to allow resuscitation with the cord intact. Methods The trolley was used when the attendance of a clinician trained in newborn life support was required at a birth. Clinicians were asked to complete a questionnaire about their experience of using the trolley. Serious adverse events were reported. Results 78 babies were managed on the trolley. Median (range) gestation was 34 weeks (24 to 41 weeks). Median (range) birth weight was2470 grams (520 to 4080 grams). The full range of resuscitation procedures has been successfully provided, although only one baby required emergency umbilical venous catheterisation. 77/78 babies had a post resuscitation temperature above 36°C. There were no adverse events. Most clinicians rated the trolley as ‘the same’, ‘better’ or ’much better’ than conventional resuscitation equipment. In most situations, the baby could be resuscitated with umbilical cord intact, although on 18 occasions the cord was too short to reach the trolley. Conclusions Immediate stabilisation at birth and resuscitation can be performed successfully and safely at the bedside using this trolley. In most cases this could be achieved with an intact umbilical cord. PMID:24885712

The rates of medication errors across three different medication dispensing and administration systems frequently used in critical access hospitals (CAHs) were analyzed. Nine CAHs agreed to participate in this prospective study and were assigned to one of three groups based on similarities in their medication-use processes: (1) less than 10 hours per week of onsite pharmacy support and no bedside barcode system, (2) onsite pharmacy support for 40 hours per week and no bedside barcode system, and (3) onsite pharmacy support for 40 or more hours per week with a bedside barcode system. Errors were characterized by severity, phase of origination, type, and cause. Characteristics of the medication being administered and a number of best practices were collected for each medication pass. Logistic regression was used to identify significant predictors of errors. A total of 3103 medication passes were observed. More medication errors originated in hospitals that had onsite pharmacy support for less than 10 hours per week and no bedside barcode system than in other types of hospitals. A bedside barcode system had the greatest impact on lowering the odds of an error reaching the patient. Wrong dose and omission were common error types. Human factors and communication were the two most frequently identified causes of error for all three systems. Medication error rates were lower in CAHs with 40 or more hours per week of onsite pharmacy support with or without a bedside barcode system compared with hospitals with less than 10 hours per week of pharmacy support and no bedside barcode system.

Wet voice as a sign of penetration/aspiration in Parkinson's disease: does testing material matter?

Sampaio, Marília; Argolo, Natalie; Melo, Ailton; Nóbrega, Ana Caline

2014-10-01

Wet voice is a perceptual vocal quality that is commonly used as an indicator of penetration and/or aspiration in clinical swallowing assessments and bedside screening tests. Our aim was to describe the clinimetric characteristics of this clinical sign using various fluid materials and one solid food in the Parkinson's disease (PD) population. Consecutive PD individuals were submitted for simultaneous fiberoptic endoscopic evaluation of swallowing (FEES) and voice recording. Speech therapists rated the presence or absence of wetness and other voice abnormalities. Two binary endpoints of FEES were selected for comparison with an index test: low penetration (LP) and low penetration and/or aspiration (LP/ASP). The accuracy of wet voice changed according to the testing material in PD patients. Overall, the specificity of this indicator was better than its sensitivity, and the wafer cookie and yogurt drink yielded the best indices. Our data show that wet voice is clearly indicative of LP or LP/ASP in PD patients in case of positive test. However, in the case of a negative result, the wet voice test should be repeated or combined with other clinical tests to include or exclude the risk of LP or LP/ASP.

To evaluate the added value of somatosensory (SEPs) and visual evoked potentials (VEPs) recorded simultaneously with routine EEG in early outcome prediction of newborns with hypoxic-ischemic encephalopathy under modern intensive care. We simultaneously recorded multichannel EEG, median nerve SEPs, and flash VEPs during the first few postnatal days in 50 term newborns with hypoxic-ischemic encephalopathy. EEG background was scored into five grades and the worst two grades were considered to indicate poor cerebral recovery. Evoked potentials were classified as absent or present. Clinical outcome was determined from the medical records at a median age of 21months. Unfavorable outcome included cerebral palsy, severe mental retardation, severe epilepsy, or death. The accuracy of outcome prediction was 98% with SEPs compared to 90% with EEG. EEG alone always predicted unfavorable outcome when it was inactive (n=9), and favorable outcome when it was normal or only mildly abnormal (n=17). However, newborns with moderate or severe EEG background abnormality could have either favorable or unfavorable outcome, which was correctly predicted by SEP in all but one newborn (accuracy in this subgroup 96%). Absent VEPs were always associated with an inactive EEG, and an unfavorable outcome. However, presence of VEPs did not guarantee a favorable outcome. SEPs accurately predict clinical outcomes in newborns with hypoxic-ischemic encephalopathy and improve the EEG-based prediction particularly in those newborns with severely or moderately abnormal EEG findings. SEPs should be added to routine EEG recordings for early bedside assessment of newborns with hypoxic-ischemic encephalopathy. Copyright © 2017 International Federation of Clinical Neurophysiology.

2011-01-01

The objective of this study was to determine the association of the bedside test of head-shaking nystagmus (HSN) with patients' self-perceived dizziness handicap as well as this test's sensitivity and specificity in unilateral peripheral vestibular hypofunction. A retrospective case-control study was performed. The study was held at an academic, tertiary referral center. Fifty-three adult patients with unilateral peripheral hypofunction defined by the caloric test of the videonystagmography with documented bedside HSN and who had completed questionnaires of self-perceived dizziness handicap were included. The sensitivity and specificity of the bedside HSN in patients and 10 healthy controls in diagnosing unilateral vestibular hypofunction defined by videonystagmographic caloric testing and by abnormal gain and symmetry of the vestibular-ocular reflex by rotary chair testing were determined. Scores of the screening test of the Dizziness Handicap Index and Functional Level Scale questionnaires were taken. When using the caloric irrigation test as the reference standard for unilateral vestibular hypofunction, the sensitivity, specificity, and positive predictive value of the bedside HSN were 31%, 96%, and 97%, respectively. When comparing with results of rotational chair testing (vestibular-ocular reflex gain and symmetry), the sensitivity of the HSN test increases to 71%. Patients with positive bedside HSN had higher scores (greater self-perceived dizziness handicap) of the Dizziness Handicap Index (P = .049) and higher (worse) scores of the Functional Level Scale (P = .0377) than those with negative bedside HSN (Wilcoxon rank test). Greater perceived handicap was correlated with a positive bedside HSN in patients with unilateral peripheral vestibulopathy. The HSN has sufficient sensitivity to be used as screening test of uncompensated vestibulopathy in this series. However, a negative HSN alone does not rule out the diagnosis of peripheral vestibular dysfunction. Copyright © 2011 Elsevier Inc. All rights reserved.

Interprofessional collaboration improves the quality of care, but integration into workflow is challenging. Although a shared conceptualization regarding bedside interprofessional rounds may enhance implementation, little work has investigated providers' perceptions of this activity. To evaluate the perceptions of nurses, attending physicians, and housestaff physicians regarding the benefits/barriers to bedside interprofessional rounds. Observational, cross-sectional survey of hospital-based medicine nurses, attending physicians, and housestaff physicians. Descriptive, nonparametric Wilcoxon rank sum and nonparametric correlation were used. Bedside interprofessional rounds were defined as "encounters including 2 physicians plus a nurse or other care provider discussing the case at the patient's bedside." Eighteen items related to "benefits" and 21 items related to "barriers" associated with bedside interprofessional rounds. Of 171 surveys sent, 149 were completed (87%). Highest-ranked benefits were related to communication/coordination, including "improves communication between nurses-physicians;" lowest-ranked benefits were related to efficiency, process, and outcomes, including "decreases length-of-stay" and "improves timeliness of consultations." Nurses reported most favorable ratings for all items (P < 0.05). Rank order for 3 provider groups showed high correlation (r = 0.92, P < 0.001). Highest-ranked barriers were related to time, including "nursing staff have limited time;" lowest-ranked barriers were related to provider- and patient-related factors, including "patient lack of comfort." Rank order of barriers among all groups showed moderate correlation (r = 0.62-0.82). Although nurses perceived greater benefit for bedside interprofessional rounds than physicians, all providers perceived coordination/teamwork benefits higher than outcomes. To the extent the results are generalizable, these findings lay the foundation for facilitating meaningful patient-centered interprofessional collaboration. © 2014 Society of Hospital Medicine.

A rapid bedside whole-blood quantitative cTnT assay has recently been developed. We evaluated the reliability of this test for the diagnosis of myocardial injury in patients with acute coronary syndrome (ACS). Whole-blood cTnT levels were measured in 96 patients with ACS using the Roche Cardiac Reader(R) rapid bedside assay device, and the results were compared with serum cTnT levels in the same patients measured by the Roche Elecsys(R) Immunoanalyzer. There were 50 patients with clinical evidence of myocardial injury and 56 without. From the qualitative point of view (reporting negative or positive tests), the results of the rapid bedside tests were identical to those obtained by the serum immunoanalyzer. From quantitative the point of view, the rapid bedside tests could not measure exact values below 0.1 ng/ml (reported negative) or above 2.0 ng/ml (reported >2.0). The measurements made by the rapid bedside tests within the range of 0.1 to 2.0 ng/ml correlated well with those of the serum immunoanalyzer (Cardiac Reader(R) cTnT=0.61, Elecsys(R) cTnT+0.12; r=0.88), but their mean values were significantly lower (1.20I0.71 vs. 1.41I1.03, p=0.0007). The rapid bedside cTnT assay correlates well with immunoanalyzer measurements between the values of 0.1 and 2.0 ng/ml. However, they tend to give significantly lower values and fail to give exact values below 0.1 and above 2.0 ng/ml, which may affect their performance in monitoring and managing patients with ACS, and limit their use in predicting outcome.

We performed a systematic review and meta-analysis to examine the accuracy of bedside ultrasound for confirmation of central venous catheter position and exclusion of pneumothorax compared with chest radiography. PubMed, Embase, Cochrane Central Register of Controlled Trials, reference lists, conference proceedings and ClinicalTrials.gov. Articles and abstracts describing the diagnostic accuracy of bedside ultrasound compared with chest radiography for confirmation of central venous catheters in sufficient detail to reconstruct 2 × 2 contingency tables were reviewed. Primary outcomes included the accuracy of confirming catheter positioning and detecting a pneumothorax. Secondary outcomes included feasibility, interrater reliability, and efficiency to complete bedside ultrasound confirmation of central venous catheter position. Investigators abstracted study details including research design and sonographic imaging technique to detect catheter malposition and procedure-related pneumothorax. Diagnostic accuracy measures included pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio. Fifteen studies with 1,553 central venous catheter placements were identified with a pooled sensitivity and specificity of catheter malposition by ultrasound of 0.82 (0.77-0.86) and 0.98 (0.97-0.99), respectively. The pooled positive and negative likelihood ratios of catheter malposition by ultrasound were 31.12 (14.72-65.78) and 0.25 (0.13-0.47). The sensitivity and specificity of ultrasound for pneumothorax detection was nearly 100% in the participating studies. Bedside ultrasound reduced mean central venous catheter confirmation time by 58.3 minutes. Risk of bias and clinical heterogeneity in the studies were high. Bedside ultrasound is faster than radiography at identifying pneumothorax after central venous catheter insertion. When a central venous catheter malposition exists, bedside ultrasound will identify four out of every five earlier than chest radiography.

Approximately 1% of term deliveries are complicated by retained products of conception. Untreated, this condition may cause bleeding, infection and intrauterine adhesions. This study assessed whether performing routine bedside uterine ultrasound immediately after manual removal of the placenta reduced the occurrence of undiagnosed, retained products of conception and its associated complications. A retrospective study was conducted using the records of patients who delivered and underwent manual removal of placenta at a single obstetrics center over a 6-year period. The outcomes of patients who were assessed using immediate bedside ultrasound were compared to a similar group who were treated based on clinical evaluation alone. All patients underwent ultrasound examination prior to discharge. Outcome variables included the rate of additional interventions (medical or surgical), abnormal pre-discharge uterine ultrasound findings, postpartum hemorrhage rate, puerperal fever and length of hospital stay. A total of 399 charts were reviewed. Immediate post-procedural ultrasound was performed in 235 patients. The remaining 164 women did not undergo immediate post-procedural ultrasound. All patients underwent an ultrasound examination prior to discharge. Among the patients who had an immediate post-procedural ultrasound, 12 (5.1%) received immediate re-intervention (2 methergine, 6 curettage and 4 manual uterine revision) vs. no intervention in the second group (p<0.001). No statistically significant difference was found between the group of patients who had immediate post-procedural ultrasound and those who did not, in the rates of postpartum hemorrhage (3.1% vs. 0.7%, p=0.13), abnormal ultrasound findings prior to discharge (14.9% vs. 14.8%, p=0.96) or additional late intervention (7.2% vs. 7.9%, p=0.79), respectively. Our findings suggest that immediate, bedside uterine ultrasound examination after manual removal of placenta might not change patient outcomes. Furthermore, it might increase unnecessary interventions. Further studies are needed to prospectively assess the benefit of routine uterine ultrasound examination after manual removal of placenta.

Integrating palliative care into intensive care units (ICUs) requires involvement of bedside nurses, who report inadequate education in palliative care. To implement and evaluate a palliative care professional development program for ICU bedside nurses. From May 2013 to January 2015, palliative care advanced practice nurses and nurse educators in 5 academic medical centers completed a 3-day train-the-trainer program followed by 2 years of mentoring to implement the initiative. The program consisted of 8-hour communication workshops for bedside nurses and structured rounds in ICUs, where nurse leaders coached bedside nurses in identifying and addressing palliative care needs. Primary outcomes were nurses' ratings of their palliative care communication skills in surveys, and nurses' identification of palliative care needs during coaching rounds. Each center held at least 6 workshops, training 428 bedside nurses. Nurses rated their skill level higher after the workshop for 15 tasks (eg, responding to family distress, ensuring families understand information in family meetings, all P < .01 vs preworkshop). Coaching rounds in each ICU took a mean of 3 hours per month. For 82% of 1110 patients discussed in rounds, bedside nurses identified palliative care needs and created plans to address them. Communication skills training workshops increased nurses' ratings of their palliative care communication skills. Coaching rounds supported nurses in identifying and addressing palliative care needs. ©2017 American Association of Critical-Care Nurses.

Swallowing changes are common in Parkinson's disease (PD). Early identification is essential to avoid complications of aspiration. To evaluate the swallowing ability of the PD patients and to correlate it with the indicators of disease progression. A total of 100 PD patients (70 males and 30 females) aged between 50 years and 70 years with varying stage, duration, and severity were enrolled in a cross-sectional study carried out between January and May 2012. A simple bedside water swallowing test was performed using standard 150 ml of water. Swallowing process was assessed under three categories-swallowing speeds (ml/s), swallowing volume (ml/swallow) and swallowing duration (s/swallow). Equal number of age and sex matched controls were also evaluated. All of them completed the task of swallowing. A mean swallowing speed (27.48 ml/s), swallowing volume (28.5 ml/s), and swallowing duration (1.05 s/swallow) was established by the control group. The PD patients showed decreased swallowing speed (7.15 ml/s in males and 6.61 ml/s in females), decreased swallowing volume (14.59 ml/swallow and 14 ml/swallow in females), and increased swallowing duration (2.37 s/swallow and 2.42 s/swallow) which are statistically significant. There was a significant positive correlation between the severity, duration, and staging of the disease with the swallowing performance and a poor correlation between the subjective reports of dysphagia and the objective performance on water swallow test. The water swallowing test is a simple bedside test to identify the swallowing changes early in PD. It is recommended to do the test in all PD Patients to detect dysphagia early and to intervene appropriately.

Background Learner benefits of tablet computer use have been demonstrated, yet there is little evidence regarding faculty tablet use for teaching. Objective Our study sought to determine if supplying faculty with tablet computers and peer mentoring provided benefits to learners and faculty beyond that of non–tablet-based teaching modalities. Methods We provided faculty with tablet computers and three 2-hour peer-mentoring workshops on tablet-based teaching. Faculty used tablets to teach, in addition to their current, non–tablet-based methods. Presurveys, postsurveys, and monthly faculty surveys assessed feasibility, utilization, and comparisons to current modalities. Learner surveys assessed perceived effectiveness and comparisons to current modalities. All feedback received from open-ended questions was reviewed by the authors and organized into categories. Results Of 15 eligible faculty, 14 participated. Each participant attended at least 2 of the 3 workshops, with 10 to 12 participants at each workshop. All participants found the workshops useful, and reported that the new tablet-based teaching modality added value beyond that of current teaching methods. Respondents developed the following tablet-based outputs: presentations, photo galleries, evaluation tools, and online modules. Of the outputs, 60% were used in the ambulatory clinics, 33% in intensive care unit bedside teaching rounds, and 7% in inpatient medical unit bedside teaching rounds. Learners reported that common benefits of tablet computers were: improved access/convenience (41%), improved interactive learning (38%), and improved bedside teaching and patient care (13%). A common barrier faculty identified was inconsistent wireless access (14%), while no barriers were identified by the majority of learners. Conclusions Providing faculty with tablet computers and having peer-mentoring workshops to discuss their use was feasible and added value. PMID:26221443

Use of an evidence-based tool for routine assessment for delirium by bedside nurses in the intensive care unit is recommended. However, little is known about patient outcomes after implementation of such a tool. To evaluate the implementation and effects of the Confusion Assessment Method for the Intensive Care Unit as a bedside assessment for delirium in a general intensive care unit in a tertiary care hospital. Charts of patients admitted to the unit during a 3-month period before implementation of the assessment tool and 1 year after implementation were reviewed retrospectively. Patient outcomes were incidence of delirium diagnosis, duration of mechanical ventilation, length of stay in the intensive care unit, and time spent in restraints. The 2 groups of patients did not differ in demographics, clinical characteristics, or predisposing factors. The groups also did not differ significantly in delirium diagnosis, duration of mechanical ventilation, length of stay in the intensive care unit, or time spent in restraints. Barriers to use of the tool included nurses' lack of confidence in performing the assessment, concerns about use of the tool in patients receiving mechanical ventilation, and lack of interdisciplinary response to findings obtained with the tool. No change in patient outcomes or diagnosis of delirium occurred 1 year after implementation of the Confusion Assessment Method for the Intensive Care Unit. Lessons learned and barriers to adoption and use, however, were identified. ©2015 American Association of Critical-Care Nurses.

Utility of Functional Hemodynamics and Echocardiography to Aid Diagnosis and Management of Shock.

PubMed

McGee, William T; Raghunathan, Karthik; Adler, Adam C

2015-12-01

The utility of functional hemodynamics and bedside ultrasonography is increasingly recognized as advantageous for both improved diagnosis and management of shock states. In contrast to conventional "static" measures, "dynamic" hemodynamic measures and bedside imaging modalities enhance pathophysiology-based comprehensive understanding of shock states and the response to therapy. The current editions of major textbooks in the primary specialties--in which clinicians routinely encounter patients in shock--including surgery, anesthesia, emergency medicine, and internal medicine continue to incorporate traditional (conventional) descriptions of shock that use well-described (but potentially misleading) intravascular pressures to classify shock states. Reliance on such intravascular pressure measurements is not as helpful as newer "dynamic" functional measures including ultrasonography to both better assess volume responsiveness and biventricular cardiac function. This review thus emphasizes the application of current functional hemodynamics and ultrasonography to the diagnosis and management of shock as a contrast to conventional "static" pressure-based measures.

Nursing students should be given opportunities to participate in clinical audits during their education. However, audit tools are seldom tested for reliability among nursing students. The aim of this study was to present reliability among nursing students using the instrument PVC assess to assess management of peripheral venous catheters (PVCs) and PVC-related signs of thrombophlebitis. PVC assess was used to assess 67 inserted PVCs in 60 patients at ten wards at a university hospital. One group of nursing students (n=4) assessed PVCs at the bedside (inter-rater reliability) and photographs of these PVCs were taken. Another group of students (n=3) assessed the PVCs in the photographs after 4 weeks (test-retest reliability). To determine reliability, proportion of agreement [P(A)] and Cohen's kappa coefficient (κ) were calculated. For bedside assessment of PVCs, P(A) ranged from good to excellent (0.80-1.0) in 55% of the 26 PVC assess items that were tested. P(A) was poor (<0.70) for two items: "adherence of inner dressing to the skin" and "PVC location." In 81% of the items, κ was between moderate and almost perfect: moderate (n=5), substantial (n=3), almost perfect (n=5). For edema at insertion site and two items on PVC dressing, κ was fair (0.21-0.40). Regarding test-retest reliability, P(A) varied between good and excellent (0.81-1) in 85%-95% of the items, and the κ ranged between moderate and almost perfect (0.41-1) in 90%-95%. PVC assess demonstrated satisfactory reliability among nursing students. However, students need training in how to use the instrument before assessing PVCs.

Patients and staff may experience adverse effects from exposure to noise. This study assessed noise levels in the pediatric intensive care unit and evaluated family and staff opinion of noise. Noise levels were recorded using a NoisePro DLX. The microphone was 1 m from the patient's head. The noise level was averaged each minute and levels above 70 and 80 dBA were recorded. The maximum, minimum, and average decibel levels were calculated and peak noise level great than 100 dBA was also recorded. A parent questionnaire concerning their evaluation of noisiness of the bedside was completed. The bedside nurse also completed a questionnaire. The average maximum dB for all patients was 82.2. The average minimum dB was 50.9. The average daily bedside noise level was 62.9 dBA. The average % time where the noise level was higher than 70 dBA was 2.2%. The average percent of time that the noise level was higher than 80 dBA was 0.1%. Patients experienced an average of 115 min/d where peak noise was greater than 100 dBA. The parents and staff identified the monitors as the major contribution to noise. Patients experienced levels of noise greater than 80 dBA. Patients experience peak noise levels in excess of 100 dB during their pediatric intensive care unit stay. Copyright © 2016 Elsevier Inc. All rights reserved.

Sonography is a crucial and versatile tool within the field of medicine. Recent advancements in technology have led to increased use of point-of-care sonography. We designed a survey to assess prior point-of-care sonography training among incoming interns at an academic teaching hospital. In 2012 and 2013, we surveyed incoming interns (n = 154 and 145, respectively) regarding point-of-care sonography training received during medical school. The survey questions included formal didactic sessions, bedside instruction, and the use of simulation technology. One-fourth (26.3% in 2012 and 23.4% in 2013) of responding interns reported having never done an ultrasound scan at the bedside. In 2012 and 2013, 55.0% and 55.6% of respondents reported never having done an ultrasound scan in a simulation center, respectively. Interns agreed that sonography education should be provided during medical school. On average, interns disagreed with the statement that sonography should be taught in residency only. There was no significant difference in the sex or general previous experience with sonography across both intern classes. Point-of-care sonography is inconsistently taught in medical school. The interns in our study also thought that sonography education should begin in medical school, and sonography should be taught by using simulation and at the bedside. © 2015 by the American Institute of Ultrasound in Medicine.

Cervical auscultation could improve the performance of bedside swallowing test to predict aspiration, especially silent aspiration. The aim of this study is to compare the predictive values of bedside swallowing test performed with and without cervical auscultation by logopedist students who had intensive training on cervical auscultation. 64 patients were included in the study. They all underwent swallowing test alone, combined swallowing test and cervical auscultation, and videofluoroscopic swallowing study as defined gold standard. Two logopedist students, at the end of their training, performed the auscultation and noted their results. 128 tests were performed, 96% of the tests were judged positive for aspiration. When comparing the results of the two different clinical tests, the detection of clinical signs is not improved by the addition of auscultation. Using a penetration aspiration scale threshold >5, the area under the curve measured for the swallowing test alone was significantly higher than that measured for the combined tests (p = 0.03) (0.66 for the swallowing test alone (95% CI between 0.49 and 0.83), and 0.50 for the combined tests (95% CI between 0.31 and 0.69). This study showed no advantage in performing cervical auscultation with bedside swallowing test. Cervical auscultation seems to hamper the assessment, mainly the perception of wet voice and laryngeal motion. These results are compatible with literature but need further confirmation using studies performed with trained logopedists.

Migraine and vertigo are common disorders, with lifetime prevalences of 16% and 7% respectively, and co-morbidity around 3.2%. Vestibular syndromes and dizziness occur more frequently in migraine patients. We investigated bedside clinical signs indicative of vestibular dysfunction in migraineurs. To test the hypothesis that vestibulo-ocular reflex, vestibulo-spinal reflex and fall risk (FR) responses as measured by 14 bedside tests are abnormal in migraineurs without vertigo, as compared with controls. Cross-sectional study including sixty individuals - thirty migraineurs, 25 women, 19-60 y-o; and 30 gender/age healthy paired controls. Migraineurs showed a tendency to perform worse in almost all tests, albeit only the Romberg tandem test was statistically different from controls. A combination of four abnormal tests better discriminated the two groups (93.3% specificity). Migraine patients consistently showed abnormal vestibular bedside tests when compared with controls.

Training auscultatory skills: computer simulated heart sounds or additional bedside training? A randomized trial on third-year medical students

PubMed Central

2010-01-01

Background The present study compares the value of additional use of computer simulated heart sounds, to conventional bedside auscultation training, on the cardiac auscultation skills of 3rd year medical students at Oslo University Medical School. Methods In addition to their usual curriculum courses, groups of seven students each were randomized to receive four hours of additional auscultation training either employing a computer simulator system or adding on more conventional bedside training. Cardiac auscultation skills were afterwards tested using live patients. Each student gave a written description of the auscultation findings in four selected patients, and was rewarded from 0-10 points for each patient. Differences between the two study groups were evaluated using student's t-test. Results At the auscultation test no significant difference in mean score was found between the students who had used additional computer based sound simulation compared to additional bedside training. Conclusions Students at an early stage of their cardiology training demonstrated equal performance of cardiac auscultation whether they had received an additional short auscultation course based on computer simulated training, or had had additional bedside training.

Rapid bedside inactivation of Ebola virus would be a solution for the safety of medical and technical staff, risk containment, sample transport, and high-throughput or rapid diagnostic testing during an outbreak. We show that the commercially available Magna Pure lysis/binding buffer used for nucleic acid extraction inactivates Ebola virus. A rapid bedside inactivation method for nucleic acid tests is obtained by simply adding Magna Pure lysis/binding buffer directly into vacuum blood collection EDTA tubes using a thin needle and syringe prior to sampling. The ready-to-use inactivation vacuum tubes are stable for more than 4 months, and Ebola virus RNA is preserved in the Magna Pure lysis/binding buffer for at least 5 weeks independent of the storage temperature. We also show that Ebola virus RNA can be manually extracted from Magna Pure lysis/binding buffer-inactivated samples using the QIAamp viral RNA minikit. We present an easy and convenient method for bedside inactivation using available blood collection vacuum tubes and reagents. We propose to use this simple method for fast, safe, and easy bedside inactivation of Ebola virus for safe transport and routine nucleic acid detection.

Bedside arterial blood gas monitoring system using fluorescent optical sensors

NASA Astrophysics Data System (ADS)

Bartnik, Daniel J.; Rymut, Russell A.

1995-05-01

We describe a bedside arterial blood gas (ABG) monitoring system which uses fluorescent optical sensors in the measurement of blood pH, PCO2 and PO2. The Point-of-Care Arterial Blood Gas Monitoring System consists of the SensiCathTM optical sensor unit manufactured by Optical Sensors Incorporated and the TramTM Critical Care Monitoring System with ABG Module manufactured by Marquette Electronics Incorporated. Current blood gas measurement techniques require a blood sample to be removed from the patient and transported to an electrochemical analyzer for analysis. The ABG system does not require removal of blood from the patient or transport of the sample. The sensor is added to the patient's existing arterial line. ABG measurements are made by drawing a small blood sample from the arterial line in sufficient quantity to ensure an undiluted sample at the sensor. Measurements of pH, PCO2 and PO2 are made within 60 seconds. The blood is then returned to the patient, the line flushed and results appear on the bedside monitor. The ABG system offers several advantages over traditional electrochemical analyzers. Since the arterial line remains closed during the blood sampling procedure the patient's risk of infection is reduced and the caregiver's exposure to blood is eliminated. The single-use, disposable sensor can be measure 100 blood samples over 72 hours after a single two-point calibration. Quality Assurance checks are also available and provide the caregiver the ability to assess system performance even after the sensor is patient attached. The ABG module integrates with an existing bedside monitoring system. This allows ABG results to appear on the same display as ECG, respiration, blood pressure, cardiac output, SpO2, and other clinical information. The small module takes up little space in the crowded intensive care unit. Performance studies compare the ABG system with an electrochemical blood gas analyzer. Study results demonstrated accurate and precise blood gas measurement of 100 samples and 72 hour performance without need for re-calibration.

Back to the Bedside: Developing a Bedside Aid for Concussion and Brain Injury Decisions in the Emergency Department

Context: Current information-rich electronic health record (EHR) interfaces require large, high-resolution screens running on desktop computers. This interface compromises the provider’s already limited time at the bedside by physically separating the patient from the doctor. The case study presented here describes a patient-centered clinical decision support (CDS) design process that aims to bring the physician back to the bedside by integrating a patient decision aid with CDS for shared use by the patient and provider on a touchscreen tablet computer for deciding whether or not to obtain a CT scan for minor head injury in the emergency department, a clinical scenario that could benefit from CDS but has failed previous implementation attempts. Case Description: This case study follows the user-centered design (UCD) approach to build a bedside aid that is useful and usable, and that promotes shared decision-making between patients and their providers using a tablet computer at the bedside. The patient-centered decision support design process focuses on the prototype build using agile software development, but also describes the following: (1) the requirement gathering phase including triangulated qualitative research (focus groups and cognitive task analysis) to understand current challenges, (2) features for patient education, the physician, and shared decision-making, (3) system architecture and technical requirements, and (4) future plans for formative usability testing and field testing. Lessons Learned: We share specific lessons learned and general recommendations from critical insights gained in the patient-centered decision support design process about early stakeholder engagement, EHR integration, external expert feedback, challenges to two users on a single device, project management, and accessibility. Conclusions: Successful implementation of this tool will require seamless integration into the provider’s workflow. This protocol can create an effective interface for shared decision-making and safe resource reduction at the bedside in the austere and dynamic clinical environment of the ED and is generalizable for these purposes in other clinical environments as well.

Current information-rich electronic health record (EHR) interfaces require large, high-resolution screens running on desktop computers. This interface compromises the provider's already limited time at the bedside by physically separating the patient from the doctor. The case study presented here describes a patient-centered clinical decision support (CDS) design process that aims to bring the physician back to the bedside by integrating a patient decision aid with CDS for shared use by the patient and provider on a touchscreen tablet computer for deciding whether or not to obtain a CT scan for minor head injury in the emergency department, a clinical scenario that could benefit from CDS but has failed previous implementation attempts. This case study follows the user-centered design (UCD) approach to build a bedside aid that is useful and usable, and that promotes shared decision-making between patients and their providers using a tablet computer at the bedside. The patient-centered decision support design process focuses on the prototype build using agile software development, but also describes the following: (1) the requirement gathering phase including triangulated qualitative research (focus groups and cognitive task analysis) to understand current challenges, (2) features for patient education, the physician, and shared decision-making, (3) system architecture and technical requirements, and (4) future plans for formative usability testing and field testing. We share specific lessons learned and general recommendations from critical insights gained in the patient-centered decision support design process about early stakeholder engagement, EHR integration, external expert feedback, challenges to two users on a single device, project management, and accessibility. Successful implementation of this tool will require seamless integration into the provider's workflow. This protocol can create an effective interface for shared decision-making and safe resource reduction at the bedside in the austere and dynamic clinical environment of the ED and is generalizable for these purposes in other clinical environments as well.

Objective We performed a systematic review and meta-analysis to examine the accuracy of bedside ultrasound for confirmation of central venous catheter position and exclusion of pneumothorax compared to chest radiography. Data Sources PubMed, EMBASE, Cochrane Central Register of Controlled Trials, reference lists, conference proceedings and ClinicalTrials.gov Study Selection Articles and abstracts describing the diagnostic accuracy of bedside ultrasound compared with chest radiography for confirmation of central venous catheters in sufficient detail to reconstruct 2×2 contingency tables were reviewed. Primary outcomes included the accuracy of confirming catheter positioning and detecting a pneumothorax. Secondary outcomes included feasibility, inter-rater reliability, and efficiency to complete bedside ultrasound confirmation of central venous catheter position. Data Extraction Investigators abstracted study details including research design and sonographic imaging technique to detect catheter malposition and procedure-related pneumothorax. Diagnostic accuracy measures included pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio. Data Synthesis 15 studies with 1553 central venous catheter placements were identified with a pooled sensitivity and specificity of catheter malposition by ultrasound of 0.82 [0.77, 0.86] and 0.98 [0.97, 0.99] respectively. The pooled positive and negative likelihood ratios of catheter malposition by ultrasound were 31.12 [14.72, 65.78] and 0.25 [0.13, 0.47]. The sensitivity and specificity of ultrasound for pneumothorax detection was nearly 100% in the participating studies. Bedside ultrasound reduced mean central venous catheter confirmation time by 58.3 minutes. Risk of bias and clinical heterogeneity in the studies were high. Conclusions Bedside ultrasound is faster than radiography at identifying pneumothorax after central venous catheter insertion. When a central venous catheter malposition exists, bedside ultrasound will identify four out of every five earlier than chest radiography. PMID:27922877

This article presents a discussion of three contemporary approaches to transforming care: Transforming Care at the Bedside, Releasing Time to Care: the Productive Ward and the work of the Studer Group(®). International studies of adverse events in hospitals have highlighted the need to focus on patient safety. The case for transformational change was identified and recently several approaches have been developed to effect this change. Despite limited evaluation, these approaches have spread and have been adopted outside their country of origin and contextual settings. Medline and CINAHL databases were searched for the years 1999-2009. Search terms included derivatives of 'transformation' combined with 'care', 'nursing', 'patient safety', 'Transforming Care at the Bedside', 'the Productive Ward' and 'Studer Group'. A comparison of the three approaches revealed similarities including: the foci of the approaches; interventions employed; and the outcomes measured. Key differences identified are the implementation models used, spread strategies and sustainability of the approaches. The approaches appear to be complementary and a hybrid of the approaches such as a blend of a top-down and bottom-up leadership strategy may offer more sustainable behavioural change. These approaches transform the way nurses do their work, how they work with others and how they view the care they provide to promote patient safety. All the approaches involve the implementation of multiple interventions occurring simultaneously to affect improvements in patient safety. The approaches are complementary and a hybrid approach may offer more sustainable outcomes. © 2011 Blackwell Publishing Ltd.

This study's purpose was to assess the characteristics of personal digital assistant (PDA) uptake and use in both clinical and classroom work for baccalaureate student nurses (BSN) within a rural Texas university. Patient care has become more complicated, risk prone, automated and costly. Efficiencies at the bedside are needed to continue to provide safe and successful within this environment. Purposive sample of nursing students using PDAs throughout their educational processes, conducted at three campus sites. The initial sample size was 105 students, followed by 94 students at end of the first semester and 75 students at curriculum completion at the end of a 2-year period. Students completed structured and open-ended questions to assess their perspectives on PDA usage. Student uptake varied in relation to overall competency, with minimal to high utilization noted, and was influenced by the current product costs. PDAs are developing into useful clinical tools by providing quick and important information for safer care. Using bedside PDAs effectively assists with maintaining patient safety, efficiency of care delivery and staff satisfaction. This study evaluates the initial implementation of PDAs by students, our future multitasking nurses. © 2011 The Authors. Journal compilation © 2011 Blackwell Publishing Ltd.

Autoregulation in the Neuro ICU.

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.

Bedsides conventional bedside training the Department of Pharmacy of Kyushu University of Health and Welfare covers advanced practices focused on new procedures expected for future pharmacists. A questionnaire survey was conducted among the 4th year students of the 6-year curriculum of the department in order to retrospectively evaluate their attitudes toward basic life support, and the necessity and feasibility of items related to the training. Sixty-nine percent of the students responded that they would provide appropriate treatment under a situation where basic life support was needed. The item regarded as most necessary and feasible before training was "treatment for basic life support--cardiopulmonary resuscitation." After training, however, "checking vital signs," "physical assessment," and "pharmacist's assistance in medication" were the items rated as equal to or higher than "treatment for basic life support--cardiopulmonary resuscitation." The lowest ranked item in terms of necessity and feasibility both before and after training was "intramuscular/subcutaneous injection," followed by "intravenous injection" and "normal intravenous collection of blood" in that order. The results of this attitude survey demonstrated that many students were willing to perform such operations as part of checking vital signs and physical assessment.

Shrestha, R; Shakya, R M; Khan A, A

2016-01-01

Background Renal colic is a common emergency department presentation. Hydronephrosis is indirect sign of urinary obstruction which may be due to obstructing ureteric calculus and can be detected easily by bedside ultrasound with minimal training. Objective To compare the accuracy of detection of hydronephrosis performed by the emergency physician with that of radiologist's in suspected renal colic cases. Method This was a prospective observational study performed over a period of 6 months. Patients >8 years with provisional diagnosis of renal colic with both the bedside ultrasound and the formal ultrasound performed were included. Presence of hydronephrosis in both ultrasounds and size and location of ureteric stone if present in formal ultrasound was recorded. The accuracy of the emergency physician detection of hydronephrosis was determined using the scan reported by the radiologists as the "gold standard" as computed tomography was unavailable. Statistical analysis was executed using SPSS 17.0. Result Among the 111 included patients, 56.7% had ureteric stone detected in formal ultrasound. The overall sensitivity, specificity, positive predictive value and negative predictive value of bedside ultrasound performed by emergency physician for detection of hydronephrosis with that of formal ultrasound performed by radiologist was 90.8%., 78.3%, 85.5% and 85.7% respectively. Bedside ultrasound and formal ultrasound both detected hydronephrosis more often in patients with larger stones and the difference was statistically significant (p=.000). Conclusion Bedside ultrasound can be potentially used as an important tool in detecting clinically significant hydronephrosis in emergency to evaluate suspected ureteric colic. Focused training in ultrasound could greatly improve the emergency management of these patients.

Does this adult patient have a blunt intra-abdominal injury?

Blunt abdominal trauma often presents a substantial diagnostic challenge. Well-informed clinical examination can identify patients who require further diagnostic evaluation for intra-abdominal injuries after blunt abdominal trauma. To systematically assess the precision and accuracy of symptoms, signs, laboratory tests, and bedside imaging studies to identify intra-abdominal injuries in patients with blunt abdominal trauma. We conducted a structured search of MEDLINE (1950-January 2012) and EMBASE (1980-January 2012) to identify English-language studies examining the identification of intra-abdominal injuries. A separate, structured search was conducted for studies evaluating bedside ultrasonography. We included studies of diagnostic accuracy for intra-abdominal injury that compared at least 1 finding with a reference standard of abdominal computed tomography, diagnostic peritoneal lavage, laparotomy, autopsy, and/or clinical course for intra-abdominal injury. Twelve studies on clinical findings and 22 studies on bedside ultrasonography met inclusion criteria for data extraction. Critical appraisal and data extraction were independently performed by 2 authors. The prevalence of intra-abdominal injury in adult emergency department patients with blunt abdominal trauma among all evidence level 1 and 2 studies was 13% (95% CI, 10%-17%), with 4.7% (95% CI, 2.5%-8.6%) requiring therapeutic surgery or angiographic embolization of injuries. The presence of a seat belt sign (likelihood ratio [LR] range, 5.6-9.9), rebound tenderness (LR, 6.5; 95% CI, 1.8-24), hypotension (LR, 5.2; 95% CI, 3.5-7.5), abdominal distention (LR, 3.8; 95% CI, 1.9-7.6), or guarding (LR, 3.7; 95% CI, 2.3-5.9) suggest an intra-abdominal injury. The absence of abdominal tenderness to palpation does not rule out an intra-abdominal injury (summary LR, 0.61; 95% CI, 0.46-0.80). The presence of intraperitoneal fluid or organ injury on bedside ultrasound assessment is more accurate than any history and physical examination findings (adjusted summary LR, 30; 95% CI, 20-46); conversely, a normal ultrasound result decreases the chance of injury detection (adjusted summary LR, 0.26; 95% CI, 0.19-0.34). Test results increasing the likelihood of intra-abdominal injury include a base deficit less than -6 mEq/L (LR, 18; 95% CI, 11-30), elevated liver transaminases (LR range, 2.5-5.2), hematuria (LR range, 3.7-4.1), anemia (LR range, 2.2-3.3), and abnormal chest radiograph (LR range, 2.5-3.8). Symptoms and signs may be most useful in combination, particularly in identification of patients who do not need further diagnostic workup. Bedside ultrasonography has the highest accuracy of all individual findings, but a normal result does not rule out an intra-abdominal injury. Combinations of clinical findings may be most useful to determine which patients do not require further evaluation, but the ideal combination of variables for identifying patients without intra-abdominal injury requires further study.

Successful strategies for integrating bedside ultrasound into undergraduate medical education.

PubMed

Palma, James K

2015-04-01

Nearly all physician specialties currently utilize bedside ultrasound, and its applications continue to expand. Bedside ultrasound is becoming a core skill for physicians; as such, it should be taught during undergraduate medical education. When ultrasound is integrated in a longitudinal manner beginning in the preclerkship phase of medical school, it not only enhances teaching the basic science topics of anatomy, physiology, and pathology but also ties those skills and knowledge to the clerkship phase and medical decision-making. Bedside ultrasound is a natural bridge from basic science to clinical science. The Uniformed Services University of the Health Sciences, F. Edward Hébert School of Medicine is currently in its fourth year of implementing an integrated ultrasound curriculum in the school of medicine. In our experience, successful integration of a bedside ultrasound curriculum should: align with unique focuses of a medical schools' mission, simplify complex anatomy through multimodal teaching, correlate to teaching of the physical examination, solidify understanding of physiology and pathology, directly link to other concurrent content, narrow differential diagnoses, enhance medical decision-making, improve procedural skills, match to year-group skillsets, develop teaching and leadership abilities, and have elective experiences for advanced topics.

ABSTRACT Objective: this study explores the process of the development of an intention to leave bedside nursing. Method: the process was studied from the perspective of 21 nurses using the grounded theory method. Data were collected using semi-structured interviews and the constant comparative method of Corbin and Strauss was used for data analysis. Results: according to the participants, the two main categories, "social image of nursing", and "culture and structure of the bedside", were the contextual factors that influence why nurses are leaving bedside care provision. Disappointment with a perceived lack of progress or improvement in the clinical experience formed primary psychosocial concerns for the participants. Competence and a process of self-control were steps taken by the participants. These, associated with interventional conditions produced the outcomes of the loss of professional commitment and desire to leave bedside nursing. "Failure to integrate personal expectations with organizational expectations: in search of escape" was the central category of the study that linked the categories together. Conclusion: the findings of this study provide useful information about the needs of nurses for overcoming the intention to leave bedside care. The identification of this process can help in recognizing emerging problems and providing solutions for them. PMID:28591301

[Priority setting and bedside rationing: a discussion of empirical findings].

PubMed

Strech, Daniel

2011-01-01

In addition to empirical forecasts on the extent of the current and future limitations on health care resources, empirical data on the status quo of bedside rationing play a significant role in developing suitable alternatives in dealing with limited financial resources. This article presents and discusses selected results of the international and German survey research on bedside rationing. Survey studies among physicians could prove world-wide that rationing decisions are made already today by individual physicians in the in- and out-patient services. In German hospitals, rationing is also a wide-spread though non-transparent and not (yet) very common phenomenon for an individual physician. Varying criteria for bedside rationing contribute to the fact that the current approach to bedside rationing leads to dissatisfaction on the part of physicians and to a potential disadvantage of certain patient groups. Explicit, i.e. transparent and systematic, ways of rationing could remedy these deficiencies and are therefore clearly preferable in this context. However, further specification of the methods of explicit rationing and a critical evaluation of their application in practice are needed. Moreover, it is mainly the quality of the underlying evidence that determines whether or not the actual decisions become more reasonable and fair by means of more explicit rationing approaches.

We aimed in this study to evaluate dysphagia in early stroke patients using a bedside screening test and flexible fiberoptic endoscopic evaluation of swallowing (FFEES) and electrophysiological evaluation (EE) methods and to compare the effectiveness of these methods. Twenty-four patients who were hospitalized in our clinic within the first 3 months after stroke were included in this study. Patients were evaluated using a bedside screening test [including bedside dysphagia score (BDS), neurological examination dysphagia score (NEDS), and total dysphagia score (TDS)] and FFEES and EE methods. Patients were divided into normal-swallowing and dysphagia groups according to the results of the evaluation methods. Patients with dysphagia as determined by any of these methods were compared to the patients with normal swallowing based on the results of the other two methods. Based on the results of our study, a high BDS was positively correlated with dysphagia identified by FFEES and EE methods. Moreover, the FFEES and EE methods were positively correlated. There was no significant correlation between NEDS and TDS levels and either EE or FFEES method. Bedside screening tests should be used mainly as an initial screening test; then FFEES and EE methods should be combined in patients who show risks. This diagnostic algorithm may provide a practical and fast solution for selected stroke patients.

Few data exist on pediatric cardiopulmonary resuscitation (CPR) quality. This study is the first to evaluate actual in-hospital pediatric CPR. We hypothesized that with bedside CPR training and corrective feedback, CPR quality can approach American Heart Association (AHA) targets. Using CPR recording/feedback defibrillators, quality of CPR was assessed for patients >or=8 years of age who suffered a cardiac arrest in the PICU or emergency department (ED). Before and during the study, a bedside CPR training program was initiated. Between October 2006 and February 2008, twenty events in 18 patients met inclusion criteria and resulted in 36749 evaluable chest compressions (CCs) during 392.3 minutes of arrest. CCs were shallow (<38 mm or <1.5 in) in 27.2% (9998 of 36749), with excessive residual leaning force (>or=2500 g) in 23.4% (8611 of 36749). Segmental analysis of the first 5 minutes of the events demonstrated that shallow CCs and excessive residual leaning force were less prevalent during the first 5 minutes. AHA targets were not achieved for CC rate in 62 (43.1%) of 144 segments, CC depth in 52 (36.1%) of 144 segments, and residual leaning force in 53 (36.8%) of 144 segments. This prospective, observational study demonstrates feasibility of monitoring in-hospital pediatric CPR. Even with bedside CPR retraining and corrective audiovisual feedback, CPR quality frequently did not meet AHA targets. Importantly, no flow fraction target of 10% was achieved. Future studies should investigate novel educational methods and targeted feedback technologies.

Background Worldwide, patients are the cornerstone of bedside teaching of medical students. In this study, the authors aimed to assess patients’ acceptability toward medical students in teaching hospitals of the Faculty of Medicine of Kuwait University. Methods Ninehundred and ninety five patients were approached in 14 teaching hospitals; 932 patients agreed to participate (refusal rate is 6.3%). A self-administered questionnaire was used to collect data. Results In general, higher acceptance of students by patients was found when there is no direct contact between the patient and the student (e.g., reading patients’ files, presenting in outpatient clinic, observing doctors performing examination or procedures) compared to other situations (e.g., performing physical examination or procedures). Pediatrics patients showed higher acceptance of students compared to patients in other specialties, while Obstetrics/Gynecology patients showed the highest refusal of students. Gender of patients (especially females) and students appeared to affect the degree of acceptance of medical students by patients. Majority of the patients (436; 46.8%) believed that the presence of medical students in hospitals improves the quality of health care. Conclusion Patients are an important factor of bedside teaching. Clinical tutors must take advantage of patients who accept medical students. Clinical tutors and medical students should master essential communication skills to convince patients in accepting students, thus improving bedside teaching. Also, using simulation and standardization should be considered to address scenarios that most patients are unwilling to allow students to participate. PMID:22509091

To assess the results of a 5-year experience with bedside burr hole for intracranial pressure (ICP) monitoring performed by intensive care physicians. Prospective, observational study in 120 patients. A general-neurologic Intensive Care Unit in a University Hospital. Patients admitted for acute neural lesion requiring ICP monitoring. A 2.71 mm burr hole was made with positioning of a subarachnoid screw, through which a miniaturized fiberoptic, tip transducer device (Camino) was advanced and inserted 2 mm in the frontal cortex. Over a 5-year period 120 patients, mainly with severe head trauma, underwent ICP monitoring. None of the planned patients was excluded because of technical difficulties. No life-threatening complications were reported, and the overall morbidity rate related to the ICP monitor was 3.3%. Complications were infectious in nature, with 2.5% wound infections and 0.8% meningitis. Although seven patients bled when opening the dura, no intracranial hematomas were recorded due to the ICP monitor. The fiberoptic device was left in place for 5 +/- 1.6 (SD) days (range 1-12 days). Five patients (4.1%) required catheter substitution due to breakage of the system components (fiberoptics). Bedside insertion of a ICP monitor performed by intensive care physicians is a safe procedure, with a complication rate comparable to other series published by neurosurgeons. The overall morbidity rate is comparable to, or even lower than, that caused by central vein catheterization.

Improving patient satisfaction with nursing communication using bedside shift report.

PubMed

Radtke, Kimberly

2013-01-01

The objective of this study was to determine if standardizing shift report improves patient satisfaction with nursing communication. Patient surveys taken after discharge from the hospital show that patients perceive nursing communication during their stay could be improved. Standardizing bedside reporting is one step toward improving communication between nurses, patients, and their families. A pilot bedside shift report process was developed on a medical/surgical intermediate care unit to improve patient satisfaction scores in the area of "nurse communicated well," with the goal of reaching 90% satisfaction rates, which increased from 76% and 78%. Peplau's interpersonal relations theory was used in the adoption of this practice. This theory is based on the idea that the nurse-patient relationship is therapeutic and that it is crucial for nurses to assess, plan, and put context behind the care delivered to their patients. Lewin's Change Theory and the tenets of unfreezing, moving, and refreezing were crucial to the implementation of this practice change. Monitoring of patient satisfaction was continued for 3 months. There was a rise in patient satisfaction in nursing communication to 87.6%, an increase from 75% in the previous 6 months. This score did not meet the goal of 90%, but did show that this practice change did impact this particular area of patient satisfaction. This process was instituted organization-wide. Reaching the goal of 90% satisfaction in the area of patient perceptions of nursing communication is the overall goal of this program.

Endoscopic evaluation of swallowing (EES) is not commonly used by gastroenterologists to evaluate swallowing in patients with dysphagia. To use transnasal endoscopy to identify factors predicting successful or failed swallowing of pureed foods in elderly patients with dysphagia. EES of pureed foods was performed by a gastroenterologist using a small-calibre transnasal endoscope. Factors related to successful versus unsuccessful swallowing of pureed foods were analyzed with regard to age, comorbid diseases, swallowing activity, saliva pooling, vallecular residues, pharyngeal residues and airway penetration⁄aspiration. Unsuccessful swallowing was defined in patients who could not eat pureed foods at bedside during hospitalization. Logistic regression analysis was used to identify independent predictors of swallowing of pureed foods. During a six-year period, 458 consecutive patients (mean age 80 years [range 39 to 97 years]) were considered for the study, including 285 (62%) men. Saliva pooling, vallecular residues, pharyngeal residues and penetration⁄aspiration were found in 240 (52%), 73 (16%), 226 (49%) and 232 patients (51%), respectively. Overall, 247 patients (54%) failed to swallow pureed foods. Multivariate logistic regression analysis demonstrated that the presence of pharyngeal residues (OR 6.0) and saliva pooling (OR 4.6) occurred significantly more frequently in patients who failed to swallow pureed foods. Pharyngeal residues and saliva pooling predicted impaired swallowing of pureed foods. Transnasal EES performed by a gastroenterologist provided a unique bedside method of assessing the ability to swallow pureed foods in elderly patients with dysphagia.

Objectives The aims of this study were to assess parents’ views of immediate neonatal care and resuscitation at birth being provided beside the mother, and their experiences of a mobile trolley designed to facilitate this bedside care. Design Qualitative study with semistructured interviews. Results were analysed using thematic analysis. Setting Large UK maternity hospital. Participants Mothers whose baby received initial neonatal care in the first few minutes of life at the bedside, and their birth partners, were eligible. 30 participants were interviewed (19 mothers, 10 partners and 1 grandmother). 5 babies required advanced neonatal resuscitation. Results 5 themes were identified: (1) Reassurance, which included ‘Baby is OK’, ‘Having baby close’, ‘Confidence in care’, ‘Knowing what's going on’ and ‘Dad as informant’; (2) Involvement of the family, which included ‘Opportunity for contact’, ‘Family involvement’ and ‘Normality’; (3) Staff communication, which included ‘Communication’ and ‘Experience’; (4) Reservations, which included ‘Reservations about witnessing resuscitation’, ‘Negative emotions’ and ‘Worries about the impact on staff’ and (5) Experiences of the trolley, which included ‘Practical issues’ and ‘Comparisons with standard resuscitation equipment’. Conclusions Families were positive about neonatal care being provided at the bedside, and felt it gave reassurance about their baby's health and care. They also reported feeling involved as a family. Some parents reported experiencing negative emotions as a result of witnessing resuscitation of their baby. Parents were positive about the trolley. PMID:26384723

Background Cardiac auscultation is a core clinical skill. However, prior studies show that trainee skills are often deficient and that clinical experience is not a proxy for competence. Objective To describe a mastery model of cardiac auscultation education and evaluate its effectiveness in improving bedside cardiac auscultation skills. Design Untreated control group design with pretest and posttest. Participants Third-year students who received a cardiac auscultation curriculum and fourth year students who did not. Intervention A cardiac auscultation curriculum consisting of a computer tutorial and a cardiac patient simulator. All third-year students were required to meet or exceed a minimum passing score (MPS) set by an expert panel at posttest. Measurements Diagnostic accuracy with simulated heart sounds and actual patients. Results Trained third-year students (n = 77) demonstrated significantly higher cardiac auscultation accuracy compared to untrained fourth year students (n = 31) in assessment of simulated heart sounds (93.8% vs. 73.9%, p < 0.001) and with real patients (81.8% vs. 75.1%, p = 0.003). USMLE scores correlated modestly with a computer-based multiple choice assessment using simulated heart sounds but not with bedside skills on real patients. Conclusions A cardiac auscultation curriculum consisting of deliberate practice with a computer-based tutorial and a cardiac patient simulator resulted in improved assessment of simulated heart sounds and more accurate examination of actual patients.

2009-01-01

Introduction Adverse outcomes following clinical deterioration in children admitted to hospital wards is frequently preventable. Identification of children for referral to critical care experts remains problematic. Our objective was to develop and validate a simple bedside score to quantify severity of illness in hospitalized children. Methods A case-control design was used to evaluate 11 candidate items and identify a pragmatic score for routine bedside use. Case-patients were urgently admitted to the intensive care unit (ICU). Control-patients had no 'code blue', ICU admission or care restrictions. Validation was performed using two prospectively collected datasets. Results Data from 60 case and 120 control-patients was obtained. Four out of eleven candidate-items were removed. The seven-item Bedside Paediatric Early Warning System (PEWS) score ranges from 0–26. The mean maximum scores were 10.1 in case-patients and 3.4 in control-patients. The area under the receiver operating characteristics curve was 0.91, compared with 0.84 for the retrospective nurse-rating of patient risk for near or actual cardiopulmonary arrest. At a score of 8 the sensitivity and specificity were 82% and 93%, respectively. The score increased over 24 hours preceding urgent paediatric intensive care unit (PICU) admission (P < 0.0001). In 436 urgent consultations, the Bedside PEWS score was higher in patients admitted to the ICU than patients who were not admitted (P < 0.0001). Conclusions We developed and performed the initial validation of the Bedside PEWS score. This 7-item score can quantify severity of illness in hospitalized children and identify critically ill children with at least one hours notice. Prospective validation in other populations is required before clinical application. PMID:19678924

Bedside teaching is essential for helping students develop skills, reasoning and professionalism, and involves the learning triad of student, patient and clinical teacher. Although current rhetoric espouses the sharing of power, the medical workplace is imbued with power asymmetries. Power is context-specific and although previous research has explored some elements of the enactment and resistance of power within bedside teaching, this exploration has been conducted within hospital rather than general practice settings. Furthermore, previous research has employed audio-recorded rather than video-recorded observation and has therefore focused on language and para-language at the expense of non-verbal communication and human-material interaction. A qualitative design was adopted employing video- and audio-recorded observations of seven bedside teaching encounters (BTEs), followed by short individual interviews with students, patients and clinical teachers. Thematic and discourse analyses of BTEs were conducted. Power is constructed by students, patients and clinical teachers throughout different BTE activities through the use of linguistic, para-linguistic and non-verbal communication. In terms of language, participants construct power through the use of questions, orders, advice, pronouns and medical/health belief talk. With reference to para-language, participants construct power through the use of interruption and laughter. In terms of non-verbal communication, participants construct power through physical positioning and the possession or control of medical materials such as the stethoscope. Using this paper as a trigger for discussion, we encourage students and clinical teachers to reflect critically on how their verbal and non-verbal communication constructs power in bedside teaching. Students and clinical teachers need to develop their awareness of what power is, how it can be constructed and shared, and what it means for the student-patient-doctor relationship within bedside teaching. © Blackwell Publishing Ltd 2013.

Background The effectiveness of skills laboratory training is widely recognized. Yet, the transfer of procedural skills acquired in skills laboratories into clinical practice has rarely been investigated. We conducted a prospective, randomised, double-blind, controlled trial to evaluate, if students having trained intravenous (IV) cannulation in a skills laboratory are rated as more professional regarding technical and communication skills compared to students who underwent bedside teaching when assessed objectively by independent video assessors and subjectively by patients. Methodology and Principal Findings 84 volunteer first-year medical students were randomly assigned to one of two groups. Three drop-outs occurred. The intervention group (IG; n = 41) trained IV cannulation in a skills laboratory receiving instruction after Peyton's ‘Four-Step Approach’. The control group (CG; n = 40) received a bedside teaching session with volunteer students acting as patients. Afterwards, performance of IV cannulation of both groups in a clinical setting with students acting as patients was video-recorded. Two independent, blinded video assessors scored students' performance using binary checklists (BC) and the Integrated Procedural Protocol Instrument (IPPI). Patients assessed students' performance with the Communication Assessment Tool (CAT) and a modified IPPI. IG required significantly shorter time needed for the performance on a patient (IG: 595.4 SD(188.1)s; CG: 692.7 SD(247.8)s; 95%CI 23.5 s to 45.1 s; p = 0.049) and completed significantly more single steps of the procedure correctly (IG: 64% SD(14) for BC items; CG: 53% SD(18); 95%CI 10.25% to 11.75%; p = 0.004). IG also scored significantly better on IPPI ratings (median: IG: 3.1; CG: 3.6; p = 0.015;). Rated by patients, students' performance and patient-physician communication did not significantly differ between groups. Conclusions Transfer of IV cannulation-related skills acquired in a skills laboratory is superior to bedside teaching when rated by independent video raters by means of IPPI and BC. It enables students to perform IV cannulation more professionally on volunteer students acting as patients. PMID:22427895

Hypertrophic scars and keloids in surgery: current concepts.

Song, Colin

2014-09-01

Hypertrophic scars and keloids remain a challenge in surgery. We appreciate that our understanding of the process at cellular and molecular level, profound as it is, when it comes to the clinical evidence much is left to be desired. Although the bench to bedside conundrum remains, the science of translational research calls for an even higher level of cooperation between the scientist and the clinician for the impetus to succeed.The clinicians alerted us to the possible theories in the pathogenesis of keloid formation, inter alia, the ischemia theory, mast cell theory, immune theory, transforming growth factor β interaction, mechanical theory, and the melanocyte stimulating hormone theory. All of the above presupposed a stimulus that would result in an uncontrolled upregulation of collagen and extracellular matrix expression in the pathogenesis of the keloid. This bedside to bench initiative, as in true science, realized more ponderables than possibilities.By the same token, research into the epidermal-mesenchymal signaling, molecular biology, genomics, and stem cell research holds much promise in the bench top arena. To assess efficacy, many scar assessment scores exist in the literature. The clinical measurement of scar maturity can aid in determining end points for therapeutics. Tissue oxygen tension and color assessment of scars by standardized photography proved to be useful.In surgery, the use of dermal substitutes holds some promise as we surmise that quality scars that arise from dermal elements, molecular and enzyme behavior, and balance. Although a systematic review shows some benefit for earlier closure and healing of wounds, no such review exists at this point in time for the use of dermal substitutes in scars.Adipose-derived stem cell, as it pertains to scars, will hopefully realize the potential of skin regeneration rather than by repair in which we are familiar with as well as the undesirable scarring as a result of healing through the inflammatory response.Translational research will bear the fruit of coordinating bench to bedside and vice versa in the interest of progress into the field of regenerative healing that will benefit the patient who otherwise suffers the myriad of scar complications.

Serious hazards of transfusion - conference report: celebration of 20 years of UK haemovigilance.

The Annual SHOT Report for incidents in 2016 was published on July 12 and celebrated of 20 years of UK haemovigilance. Components are very safe, related in part to risk-reduction measures triggered by SHOT reporting. Transfusion-related acute lung injury is now very rare (all plasma components are provided from male donors), and infection transmission is also uncommon - a single transmission of hepatitis E in 2016 and no bacterial transmissions. Human factors (errors) account for 87% of all reports. Deaths and major morbidity most often result from transfusion-associated circulatory overload. Wrong transfusions and deaths from ABO-incompatible transfusion can be reduced by correct bedside checks. It is notable that information technology systems may not be safe. Standardisation is required for flags and alerts. SHOT key recommendations include: assess patients for transfusion-associated circulatory overload prior to transfusion. Be like a pilot - use a bedside checklist when setting up the transfusion. © 2017 British Blood Transfusion Society.

The value of the high gain, signal averaged electrocardiogram combined with 24 hour electrocardiographic monitoring in the prediction of arrhythmic events was assessed in 159 patients in the first week after myocardial infarction. Eleven patients (7%) suffered arrhythmic events during a mean (SD) of 12 (6) months of follow up (range 2-22, median 13 months). The combination of high gain, signal averaged electrocardiography and 24 hour electrocardiographic monitoring was more accurate than either technique alone or than clinical information collected during admission in predicting these events. The combination identified a high risk group of 13 (8%) patients, with an arrhythmic event rate of 62% and a low risk group with an event rate of 2%. The combination of high gain, signal averaged electrocardiography and 24 hour electrocardiographic monitoring in the first week after myocardial infarction provides a rapid, cheap, and non-invasive bedside method for the prediction of arrhythmias.

2014-01-01

Point of care testing, is the term commonly applied to the bedside tests performed in sick patients. Common clinical conditions encountered in pediatric emergency rooms are respiratory, gastro-intestinal, infections and cardiac. Emergencies at most of the places, especially developing countries are overburdened. Availability of tests like arterial blood gas, lactate, electrolytes and procalcitonin, bedside tests or point of care tests can help identify sick patients quickly. Abnormalities like acid-base disturbances and dyselectrolytemias can be dealt with instantly, thus improving the overall prognosis. Lactate levels in emergency give the earliest clue to cardiovascular compromise and poor tissue perfusion. Procalcitonin has recently gained significant importance as an acute phase reactant for early identification of sepsis. Decisions for initiating or withholding antibiotic therapy can also be taken based on procalcitonin levels in emergency. Bedside estimation of serum electrolytes, blood gas analysis and procalcitonin thus facilitate the clinical evaluation and management of critical patients. An extensive literature review of current status of these investigations as point of care tests is appraised here. PMID:25337488

A feasibility study on bedside upper airway ultrasonography compared to waveform capnography for verifying endotracheal tube location after intubation

PubMed Central

2013-01-01

Background In emergency settings, verification of endotracheal tube (ETT) location is important for critically ill patients. Ignorance of oesophageal intubation can be disastrous. Many methods are used for verification of the endotracheal tube location; none are ideal. Quantitative waveform capnography is considered the standard of care for this purpose but is not always available and is expensive. Therefore, this feasibility study is conducted to compare a cheaper alternative, bedside upper airway ultrasonography to waveform capnography, for verification of endotracheal tube location after intubation. Methods This was a prospective, single-centre, observational study, conducted at the HRPB, Ipoh. It included patients who were intubated in the emergency department from 28 March 2012 to 17 August 2012. A waiver of consent had been obtained from the Medical Research Ethics Committee. Bedside upper airway ultrasonography was performed after intubation and compared to waveform capnography. Specificity, sensitivity, positive and negative predictive value and likelihood ratio are calculated. Results A sample of 107 patients were analysed, and 6 (5.6%) had oesophageal intubations. The overall accuracy of bedside upper airway ultrasonography was 98.1% (95% confidence interval (CI) 93.0% to 100.0%). The kappa value (Κ) was 0.85, indicating a very good agreement between the bedside upper airway ultrasonography and waveform capnography. Thus, bedside upper airway ultrasonography is in concordance with waveform capnography. The sensitivity, specificity, positive predictive value and negative predictive value of bedside upper airway ultrasonography were 98.0% (95% CI 93.0% to 99.8%), 100% (95% CI 54.1% to 100.0%), 100% (95% CI 96.3% to 100.0%) and 75.0% (95% CI 34.9% to 96.8%). The likelihood ratio of a positive test is infinite and the likelihood ratio of a negative test is 0.0198 (95% CI 0.005 to 0.0781). The mean confirmation time by ultrasound is 16.4 s. No adverse effects were recorded. Conclusions Our study shows that ultrasonography can replace waveform capnography in confirming ETT placement in centres without capnography. This can reduce incidence of unrecognised oesophageal intubation and prevent morbidity and mortality. Trial registration National Medical Research Register NMRR11100810230. PMID:23826756

This article presents the bedside nurses' perspectives on their experience with conducting an evidence based practice project. This is especially important in the climate of hospitals working to achieve Magnet Recognition. The facilitators and barriers to project design and completion are discussed in detail. Strategies to overcome barriers are presented. Facilitators for bedside nurses include motivation and professional development. Most common barriers were lack of time and limited knowledge about the process. Interventions aimed at research utilization can be successful when mindful of commonly understood barriers to project completion with steps taken to resolve those barriers.

A system to provide surveillance, diagnosis, and protocolized management of surgical intensive care unit (SICU) sepsis was undertaken as a performance improvement project. A system for sepsis management was implemented for SICU patients using paper followed by a computerized system. The hypothesis was that the computerized system would be associated with improved process and outcomes. A system was designed to provide early recognition and guide patient-specific management of sepsis including (1) modified early warning signs-sepsis recognition score (MEWS-SRS; summative point score of ranges of vital signs, mental status, white blood cell count; after every 4 hours) by bedside nurse; (2) suspected site assessment (vascular access, lung, abdomen, urinary tract, soft tissue, other) at bedside by physician or extender; (3) sepsis management protocol (replicable, point-of-care decisions) at bedside by nurse, physician, and extender. The system was implemented first using paper and then a computerized system. Sepsis severity was defined using standard criteria. In January to May 2012, a paper system was used to manage 77 consecutive sepsis encounters (3.9 ± 0.5 cases per week) in 65 patients (77% male; age, 53 ± 2 years). In June to December 2012, a computerized system was used to manage 132 consecutive sepsis encounters (4.4 ± 0.4 cases per week) in 119 patients (63% male; age, 58 ± 2 years). MEWS-SRS elicited 683 site assessments, and 201 had sepsis diagnosis and protocol management. The predominant site of infection was abdomen (paper, 58%; computer, 53%). Recognition of early sepsis tended to occur more using the computerized system (paper, 23%; computer, 35%). Hospital mortality rate for surgical ICU sepsis (paper, 20%; computer, 14%) was less with the computerized system. A computerized sepsis management system improves care process and outcome. Early sepsis is recognized and managed with greater frequency compared with severe sepsis or septic shock. The system has a beneficial effect as a clinical standard of care for SICU patients.

Medical students' time is limited, so efficiency in medical education is valued. This research project aimed to determine the most effective means to teach bedside ultrasound to medical students in a 1-week training course. We hypothesized that the best method would include a combination of podcasts and hands-on teaching; therefore, there would be a statistically significant difference among the various methods of teaching. Medical students were randomly assigned to 3 groups. All groups attended a 50-minute hands-on bedside ultrasound training session. Students in the first group attended a 50-minute live lecture before the hands-on session, whereas students in the second group watched a podcast that covered the same material as the live lecture. Students in the third group served as the control and only attended the hands-on sessions. Five topics were covered during the course: (1) introduction to ultrasound, (2) pulmonary ultrasound, (3) cardiac ultrasound, (4) hepatobiliary ultrasound, and (5) focused assessment with sonography for trauma. Students completed a 20-question pre- and post-training quiz that covered basic ultrasound principles. Students also conducted a focused assessment with sonography for trauma examination for the practical portion of their evaluation. Students' pre- to post-training quiz scores increased from 33.6% to 72.6% correct in the lecture group (n = 21; P < .0001), from 40.7% to 75.5% correct in the podcast group (n = 20; P< .0001), and from 37.8% to 70.0% correct in the control group (n = 23; P< .0001). Data analysis of written and practical examination scores showed no significant differences among the groups [F(2,61) = 0.885; P = .418; F(2,60) = 1.739; P = .184, respectively]. These results suggest that all 3 methods are equally effective in teaching novice medical students basic ultrasound knowledge and skills. © 2015 by the American Institute of Ultrasound in Medicine.

To explore the phenomenon of assessing changes in patients' conditions in intensive care units from the perspectives of experienced intensive care nurses. Providing safe care for patients in intensive care units requires an awareness and perception of the signs that indicate changes in a patient's condition. Nurses in intensive care units play an essential role in preventing the deterioration of a patient's condition and in improving patient outcomes. This hermeneutic phenomenological study conducted close observations and in-depth interviews with 11 intensive care nurses. The nurses' experience ranged from 7 to 28 years in the intensive care unit. Data were collected at two intensive care units in two Norwegian university hospitals. The analysis was performed using the reflective methods of van Manen. An overarching theme of 'sensitive situational attention' was identified, in which the nurses were sensitive in relation to a patient and understood the significance of a given situation. This theme was further unfolded in four subthemes: (1) being sensitive and emotionally present, (2) being systematic and concentrating, (3) being physically close to the bedside and (4) being trained and familiar with the routines. Nurses understand each patient's situation and foresee clinical eventualities through a sensitive and attentive way of thinking and working. This requires nurses to be present at the bedside with both their senses (sight, hearing, smell and touch) and emotions and to work in a concentrated and systematic manner. Knowledge about the unique patient exists in interplay with past experiences and medical knowledge, which are essential for nurses to understand the situation. Clinical practice should develop routines that enable nurses to be present at the bedside and to work in a concentrated and systematic manner. Furthermore, providing safe care requires nurses to be sensitive and attentive to each patient's unique situation. © 2016 British Association of Critical Care Nurses.

A rising number of acute hospitals in the UK have been providing patients with bedside entertainment services (BES) since 1995. However, their effect on postoperative patient mobility has not been explored. The aim of this prospective randomised clinical trial was to compare the level of postoperative physical activity and length of in-hospital stay of patients undergoing cardiac surgery depending on whether they had access to BES or not. One hundred patients requiring elective cardiac surgery were randomised to receive access to BES (52 patients) or not (48 patients). Pedometers were used to quantify postoperative physical activity for 5 days. To assess the significance of the effect of intervention (TV off or on) on the pedometer counts over time a mixed effect Poisson regression model is used, with the time varying aspect as random component. The potential influence of gender difference and age on pedometer counts were assessed by incorporating these two factors as covariates in the Poisson model. On average, patients with no access to BES walked more than those with BES access. This difference ranged between 192 and 609 steps in favour of the first group for each individual postoperative day. Patients with no access to BES were 84% more likely (risk ratio: 1.84, 95% CI: 1.29-2.63) to walk higher number of steps than patients with access to BES. On average, participants with access to BES were likely to stay longer in hospital (median of 7 days with interquartile range 6-7 days), than participants with no access to BES (median of 6 days with interquartile range 5-7 days), however the difference did not reach statistical significance. We have demonstrated that the bedside entertainment systems may have an adverse effect on post cardiac surgery patient ambulation and may contribute to an increase in hospital stay.

There is still unmet demand for developing powerful approaches to produce polymeric nanoplatforms with versatile functions and broad applications, which are essential for the successful bench-to-bedside translation of polymeric nanotherapeutics developed in the laboratory. We have discovered a facile, convenient, cost-effective and easily scalable one-pot strategy to assemble various lipophilic therapeutics bearing carboxyl groups into nanomedicines, through which highly effective cargo loading and nanoparticle formation can be achieved simultaneously. Besides dramatically improving water solubility, the assembled nanopharmaceuticals showed significantly higher bioavailability and much better therapeutic activity. These one-pot assemblies may also serve as nanocontainers to effectively accommodate other highly hydrophobic drugs such as paclitaxel (PTX). PTX nanomedicines thus formulated display strikingly enhanced in vitro antitumor activity and can reverse the multidrug resistance of tumor cells to PTX therapy. The special surface chemistry offers these assembled entities the additional capability of efficiently packaging and efficaciously transfecting plasmid DNA, with a transfection efficiency markedly higher than that of commonly used positive controls. Consequently, this one-pot assembly approach provides a facile route to multifunctional nanoplatforms for simultaneous delivery of multiple therapeutics with improved therapeutic significance.

Magnetic nanoparticles (MNPs) accumulate at disease sites with the aid of magnetic fields; biodegradable MNPs can be designed to facilitate drug delivery, influence disease diagnostics, facilitate tissue regeneration and permit protein purification. Because of their limited toxicity, MNPs are widely used in theranostics, simultaneously facilitating diagnostics and therapeutics. To realize therapeutic end points, iron oxide nanoparticle cores (5–30 nm) are encapsulated in a biocompatible polymer shell with drug cargos. Although limited, the toxic potential of MNPs parallels magnetite composition, along with shape, size and surface chemistry. Clearance is hastened by the reticuloendothelial system. To surmount translational barriers, the crystal structure, particle surface and magnetic properties of MNPs need to be optimized. With this in mind, we provide a comprehensive evaluation of advancements in MNP synthesis, functionalization and design, with an eye towards bench-to-bedside translation. PMID:24646020

Early bedside care during preclinical medical education: can technology-enhanced patient simulation advance the Flexnerian ideal?

2010-02-01

Flexner wanted medical students to study at the patient bedside-a remarkable innovation in his time-so that they could apply science to clinical care under the watchful eye of senior physicians. Ever since his report, medical schools have reserved the latter years of their curricula for such an "advanced" apprenticeship, providing clinical clerkship experiences only after an initial period of instruction in basic medical sciences. Although Flexner codified the segregation of preclinical and clinical instruction, he was committed to ensuring that both domains were integrated into a modern medical education. The aspiration to fully integrate preclinical and clinical instruction continues to drive medical education reform even to this day. In this article, the authors revisit the original justification for sequential preclinical-clinical instruction and argue that modern, technology-enhanced patient simulation platforms are uniquely powerful for fostering simultaneous integration of preclinical-clinical content in a way that Flexner would have applauded. To date, medical educators tend to focus on using technology-enhanced medical simulation in clinical and postgraduate medical education; few have devoted significant attention to using immersive clinical simulation among preclinical students. The authors present an argument for the use of dynamic robot-mannequins in teaching basic medical science, and describe their experience with simulator-based preclinical instruction at Harvard Medical School. They discuss common misconceptions and barriers to the approach, describe their curricular responses to the technique, and articulate a unifying theory of cognitive and emotional learning that broadens the view of what is possible, feasible, and desirable with simulator-based medical education.

Bedside red cell volumetry by low-dose carboxyhaemoglobin dilution using expiratory gas analysis.

2006-02-01

We developed a non-invasive, continuous, high-resolution method of measuring carboxyhaemoglobin fraction (COHb%) using expiratory gas analysis (EGA). We assessed whether application of EGA to carboxyhaemoglobin dilution provides red cell volume (RCV) measurement with accuracy equivalent to that of CO-haemoximetry, with a smaller infusion volume of carbon-monoxide-saturated autologous blood (COB). Method. We assessed the agreement between repeated COHb% measurements by EGA and simultaneous measurement by CO-haemoximetry, using Bland and Altman plot, in healthy subjects and patients with artificially controlled ventilation and no radiological evidence of pulmonary oedema or atelectasis. We assessed the agreement between RCV measurements by EGA with infusion of 20 ml of COB (RCVEGA) and RCV measurements by CO-haemoximetry with infusion of 100 ml of COB (RCVHEM), in healthy subjects. The 'limits of agreement' between COHb% measurement by EGA (1 min average) and CO-haemoximetry were -0.09 and 0.08% in healthy subjects, and -0.11 and 0.09% in patients. Given the resolution of CO-haemoximetry (0.1%), the accuracy of EGA was equivalent to or greater than that of CO-haemoximetry. The 'limits of agreement' between RCVEGA and RCVHEM were -0.14 and 0.15 litre. Given the average resolution of RCVHEM (0.14 litre), the accuracy of RCVEGA was equivalent to that of RCVHEM. EGA provided non-invasive, accurate, continuous, high-resolution COHb% measurements. Applying EGA to carboxyhaemoglobin dilution, we achieved RCV measurements with accuracy equivalent to that of CO-haemoximetry, with one-fifth of the COB infusion volume. However, clinical application of the method is limited to patients with no radiological evidence of pulmonary oedema or atelectasis.

In this article, the authors describe the development and pilot testing of an electronic bedside communication center (eBCC) prototype to improve access to health information for hospitalized adults and their family caregivers. Focus groups were used to identify improvements for the initial eBCC prototype developed by the research team. Face-to-face bedside interviews and questions were presented while patients used the eBCC for usability testing to drive further development. Qualitative methods within an iterative, participatory approach supported the development of an eBCC prototype that was considered both easy to use and helpful for accessing tailored patient information during an inpatient hospitalization to receive acute care.

Perinatal brain injury remains a significant cause of infant mortality and morbidity, but there is not yet an effective bedside tool that can accurately screen for brain injury, monitor injury evolution, or assess response to therapy. The energy used by neurons is derived largely from tissue oxidative metabolism, and neural hyperactivity and cell death are reflected by corresponding changes in cerebral oxygen metabolism (CMRO₂). Thus, measures of CMRO₂ are reflective of neuronal viability and provide critical diagnostic information, making CMRO₂ an ideal target for bedside measurement of brain health. Brain-imaging techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT) yield measures of cerebral glucose and oxygen metabolism, but these techniques require the administration of radionucleotides, so they are used in only the most acute cases. Continuous-wave near-infrared spectroscopy (CWNIRS) provides non-invasive and non-ionizing radiation measures of hemoglobin oxygen saturation (SO₂) as a surrogate for cerebral oxygen consumption. However, SO₂ is less than ideal as a surrogate for cerebral oxygen metabolism as it is influenced by both oxygen delivery and consumption. Furthermore, measurements of SO₂ are not sensitive enough to detect brain injury hours after the insult, because oxygen consumption and delivery reach equilibrium after acute transients. We investigated the possibility of using more sophisticated NIRS optical methods to quantify cerebral oxygen metabolism at the bedside in healthy and brain-injured newborns. More specifically, we combined the frequency-domain NIRS (FDNIRS) measure of SO2 with the diffuse correlation spectroscopy (DCS) measure of blood flow index (CBFi) to yield an index of CMRO₂ (CMRO₂i). With the combined FDNIRS/DCS system we are able to quantify cerebral metabolism and hemodynamics. This represents an improvement over CWNIRS for detecting brain health, brain development, and response to therapy in neonates. Moreover, this method adheres to all neonatal intensive care unit (NICU) policies on infection control and institutional policies on laser safety. Future work will seek to integrate the two instruments to reduce acquisition time at the bedside and to implement real-time feedback on data quality to reduce the rate of data rejection.

Clinical Skills Assessment in the Twenty-First Century.

PubMed

Elder, Andrew

2018-05-01

Clinical skills remain fundamental to the practice of medicine and form a core component of the professional identity of the physician. However, evidence exists to suggest that the practice of some clinical skills is declining, particularly in the United States. A decline in practice of any skill can lead to a decline in its teaching and assessment, with further decline in practice as a result. Consequently, assessment not only drives learning of clinical skills, but their practice. This article summarizes contemporary approaches to clinical skills assessment that, if more widely adopted, could support the maintenance and reinvigoration of bedside clinical skills.

Assessment of the fetus: relevance to brain injury.

PubMed

Hill, A

1989-06-01

This article reviews recent advances in the antepartum and intrapartum assessment of the fetus and their relationship to brain injury in the newborn. The antepartum assessment involves observation of fetal body and eye movements, the nonstress and contraction stress tests, measurement of amniotic fluid volume, the fetal biophysical score and measurement of fetoplacental blood physiology. There is evidence to suggest that seizures may either be epileptic in origin or initiated and mediated by nonepileptic mechanisms. Therapeutic decisions may be based on bedside assessment of the pathophysiology of observed seizures. Although EEG/video monitoring plays a role in the management of neonatal seizures, clinical evaluation of the seizures may provide initial data critical to decisions concerning immediate management.

Transient-evoked otoacoustic emission (TEOAE) is a well-established screening tool for universal newborn hearing screening. The aims of this study are to measure the effects of background noise on recording of TEOAE and the duration required to complete the test at various noise levels. This study is a prospective study from June 2006 until May 2007. The study population were newborns from postnatal wards who were delivered at term pregnancy. Newborns who were more than 8-h old and passed a hearing screening testing using screening auditory brainstem response (SABRe) were further tested with TEOAE in four different test environments [isolation room in the ward during non-peak hour (E1), isolation room in the ward during peak hour (E2), maternal bedside in the ward during non-peak hour (E3) and maternal bedside in the ward during peak hour (E4)]. This study showed that test environment significantly influenced the time required to complete testing in both ears with F [534.23] = 0.945; P < 0.001 on the right ear and F [636.54] = 0.954; P < 0.001 on the left. Our study revealed that TEOAE testing was efficient in defining the presence of normal hearing in our postnatal wards at maternal bedside during non-peak hour with a specificity of 96.8%. Our study concludes that background noise levels for acceptable and accurate TEOAE recording in newborns should not exceed 65 dB A. In addition, when using TEOAE assessment in noisy environments, the time taken to obtain accurate results will greatly increase.

Monitoring of physiologic parameters in critically ill patients is currently performed by threshold alarm systems with high sensitivity but low specificity. As a consequence, a multitude of alarms are generated, leading to an impaired clinical value of these alarms due to reduced alertness of the intensive care unit (ICU) staff. To evaluate a new alarm procedure, we currently generate a database of physiologic data and clinical alarm annotations. Data collection is taking place at a 12-bed medical ICU. Patients with monitoring of at least heart rate, invasive arterial blood pressure, and oxygen saturation are included in the study. Numerical physiologic data at 1-second intervals, monitor alarms, and alarm settings are extracted from the surveillance network. Bedside video recordings are performed with network surveillance cameras. Based on the extracted data and the video recordings, alarms are clinically annotated by an experienced physician. The alarms are categorized according to their technical validity and clinical relevance by a taxonomy system that can be broadly applicable. Preliminary results showed that only 17% of the alarms were classified as relevant, and 44% were technically false. The presented system for collecting real-time bedside monitoring data in conjunction with video-assisted annotations of clinically relevant events is the first allowing the assessment of 24-hour periods and reduces the bias usually created by bedside observers in comparable studies. It constitutes the basis for the development and evaluation of "smart" alarm algorithms, which may help to reduce the number of alarms at the ICU, thereby improving patient safety.

OBJECTIVE To determine if structured teaching of bedside cardiac examination skills improves medical residents' examination technique and their identification of key clinical findings. DESIGN Firm-based single-blinded controlled trial. SETTING Inpatient service at a university-affiliated public teaching hospital. PARTICIPANTS Eighty Internal Medicine residents. METHODS The study assessed 2 intervention groups that received 3-hour bedside teaching sessions during their 4-week rotation using either: (1) a traditional teaching method, “demonstration and practice” (DP) (n=26) or (2) an innovative method, “collaborative discovery” (CD) (n=24). The control group received their usual ward teaching sessions (n=25). The main outcome measures were scores on examination technique and correct identification of key clinical findings on an objective structured clinical examination (OSCE). RESULTS All 3 groups had similar scores for both their examination technique and identification of key findings in the preintervention OSCE. After teaching, both intervention groups significantly improved their technical examination skills compared with the control group. The increase was 10% (95% confidence interval [CI] 4% to 17%) for CD versus control and 12% (95% CI 6% to 19%) for DP versus control (both P<.005) equivalent to an additional 3 to 4 examination skills being correctly performed. Improvement in key findings was limited to a 5% (95% CI 2% to 9%) increase for the CD teaching method, CD versus control P=.046, equivalent to the identification of an additional 2 key clinical findings. CONCLUSIONS Both programs of bedside teaching increase the technical examination skills of residents but improvements in the identification of key clinical findings were modest and only demonstrated with a new method of teaching.

This study was designed to test the usefulness of a bedside assay as compared to a laboratory method of troponin testing to predict adverse cardiac outcome of chest pain patients. We studied 358 ER visits of patients suspected of a non ST-elevation acute coronary syndrome. cTnI (Immulite, DPC) on a lab analyser and cTnT (Cardiac Reader, Roche) at bedside were measured at baseline. The between-assay level of concordance, reporting turnaround times and clinical outcomes during 180 days of follow-up were assessed. Death and myocardial infarction were then evaluated according to troponin result, either concordant negative, discordant or concordant positive. Discordance occurred in 11.4% (41/358) of cases. The proportion of patients with a positive cTnI and negative cTnT result (8.9%) versus the reverse (2.5%) differed significantly (p<0.001). The median time gained using the rapid test was 72 min. The rate of death and/or MI was 25% (10/40) among patients with discordant results as compared to 7.5% (17/228) with a concordant negative result (p<0.001). All patients from the discordant group with an event had a positive cTnI result, while cTnT was negative. Patients with a discordant reading were at high risk of adverse cardiac outcome, which was only identified by the laboratory cTnI assay. Markedly, the use of the rapid assay saved time at the expense of clinical sensitivity.

A potential barrier to patient discharge from hospital is communication problems between the treating team and the patient or family regarding discharge planning. To determine if a bedside 'Leaving Hospital Information Sheet' increases patient and family's knowledge of discharge date and destination and the name of the key clinician primarily responsible for team-patient communication. This article is a 'before-after' study of patients, their families and the interdisciplinary ward-based clinical team. Outcomes assessed pre-implementation and post-implementation of a bedside 'Leaving Hospital Information Sheet' containing discharge information for patients and families. Patients and families were asked if they knew the key clinician for team-patient communication and the proposed discharge date and discharge destination. Responses were compared with those set by the team. Staff were surveyed regarding their perceptions of patient awareness of discharge plans and the benefit of the 'Leaving Hospital Information Sheet'. Significant improvement occurred regarding patients' knowledge of their key clinician for team-patient communication (31% vs 75%; P = 0.0001), correctly identifying who they were (47% vs 79%; P = 0.02), and correctly reporting their anticipated discharge date (54% vs 86%; P = 0.004). There was significant improvement in the family's knowledge of the anticipated discharge date (78% vs 96%; P = 0.04). Staff reported the 'Leaving Hospital Information Sheet' assisted with communication regarding anticipated discharge date and destination (very helpful n = 11, 39%; a little bit helpful n = 11, 39%). A bedside 'Leaving Hospital Information Sheet' can potentially improve communication between patients, families and their treating team. © 2016 Royal Australasian College of Physicians.

BACKGROUND: Endoscopic evaluation of swallowing (EES) is not commonly used by gastroenterologists to evaluate swallowing in patients with dysphagia. OBJECTIVE: To use transnasal endoscopy to identify factors predicting successful or failed swallowing of pureed foods in elderly patients with dysphagia. METHODS: EES of pureed foods was performed by a gastroenterologist using a small-calibre transnasal endoscope. Factors related to successful versus unsuccessful swallowing of pureed foods were analyzed with regard to age, comorbid diseases, swallowing activity, saliva pooling, vallecular residues, pharyngeal residues and airway penetration/aspiration. Unsuccessful swallowing was defined in patients who could not eat pureed foods at bedside during hospitalization. Logistic regression analysis was used to identify independent predictors of swallowing of pureed foods. RESULTS: During a six-year period, 458 consecutive patients (mean age 80 years [range 39 to 97 years]) were considered for the study, including 285 (62%) men. Saliva pooling, vallecular residues, pharyngeal residues and penetration/aspiration were found in 240 (52%), 73 (16%), 226 (49%) and 232 patients (51%), respectively. Overall, 247 patients (54%) failed to swallow pureed foods. Multivariate logistic regression analysis demonstrated that the presence of pharyngeal residues (OR 6.0) and saliva pooling (OR 4.6) occurred significantly more frequently in patients who failed to swallow pureed foods. CONCLUSIONS: Pharyngeal residues and saliva pooling predicted impaired swallowing of pureed foods. Transnasal EES performed by a gastroenterologist provided a unique bedside method of assessing the ability to swallow pureed foods in elderly patients with dysphagia. PMID:23936875

To determine the value of bedside heart-type fatty acid binding protein in diagnosis of cardiac syncope in patients presenting with syncope or presyncope. The prospective study was conducted at Ankara Numune Training and Research Hospital, Ankara, Turkey, between September 1, 2010, and January 1, 2011, and comprised patients aged over 18 years who presented with syncope or presyncope. Patients presenting to emergency department within 4 hours of syncope or presyncope underwent a bedside heart-type fatty acid binding protein test measurement. SPSS 16 was used for statistical analysis. Of the 100 patients evaluated, 22(22%) were diagnosed with cardiac syncope. Of them, 13(59.1%) patients had a positive and 9(40.9%) had a negative heart-type fatty acid binding protein result. Consequently, the test result was 12.64 times more positive in patients with cardiac syncope compared to those without. Bedside heart-type fatty acid binding protein, particularly at early phase of myocardial injury, reduces diagnostic and therapeutic uncertainity of cardiac origin in syncope patients.

Lower limb paresis is one of the main determinants of postural transferring, standing and walking disability in patients with stroke. Early prognosis of recovery of lower limb function and of related functional disability is an important issue in neurorehabilitation clinical practice. Aim of this study was to assess the relationship between active ankle dorsiflexion and the Mingazzini manoeuvre with the prognosis of lower limb function and of postural transferring, standing and walking ability in patients with stroke. This was a longitudinal study with prospectively collected data. University hospital. The study included 53 patients with first unilateral brain ischemic stroke. Patients were evaluated initially (mean 4.02 days) and approximately at six months (mean 178.6 days) after stroke. Initial assessment included active ankle dorsiflexion and the Mingazzini manoeuvre. The assessment after six months included three outcome measures evaluating the rate of improvement of lower limb function and of postural transferring, standing and walking ability (Postural Assessment Scale for Stroke patients, Functional Ambulation Category, Motricity Index leg subtest). The active ankle dorsiflexion showed to be related with the prognosis of lower limb function and of walking ability, while the Mingazzini manoeuvre was related with the improvement of postural transferring and standing ability. Active ankle dorsiflexion and the Mingazzini manoeuvre are related with the prognosis of lower limb function and of postural transferring, standing and walking ability in patients with stroke. These simple bedside tests give a picture of improvement potential of motor activities connected to lower limb function in patients with acute stroke.

To evaluate the effect of a short-term training program in emergency ultrasound on physician skills and attitudes in southwestern Tanzania. Eight registrar physicians at Mbeya Zonal Referral Hospital (Mbeya, Tanzania) underwent a 5-day course in bedside emergency ultrasound, focusing primarily on the focused assessment with sonography for trauma examination, including didactic sessions, practical sessions, and on-job training. The impact on ultrasound knowledge was assessed by pretest and posttest evaluations. Provider skill was evaluated by a standardized observed simulated patient encounter. Attitudes toward ultrasound training, utility, and self-confidence were assessed by a post-training questionnaire. All 8 physicians who began the training completed the course and successfully passed their objective structured clinical examination. There was a statistically significant improvement in written ultrasound test scores from 31% to 66% (P < .01) after the course. Most trainees felt confident performing and interpreting a basic focused assessment with sonography for trauma examination at the end of the course, and 7 of 8 stated that they would consider paying tuition for similar courses in the future. Main concerns with the course revolved around insufficient time dedicated to practicing under supervision. Registrar physicians in Tanzania can effectively learn basic emergency ultrasound skills in a short-term training program. Similar future programs may consider heavier emphasis on practical hands-on training with experts. Ongoing data collection is required to understand the true impact of such training on long-term ultrasound use and patient outcomes. © 2017 by the American Institute of Ultrasound in Medicine.

Identification of the risk of falls is important among older inpatients. This study aims to examine performance criteria (i.e.; sensitivity, specificity, positive predictive value, negative predictive value and accuracy) for fall prediction resulting from a nurse assessment and an artificial neural networks (ANNs) analysis in older inpatients hospitalized in acute care medical wards. A total of 848 older inpatients (mean age, 83.0±7.2 years; 41.8% female) admitted to acute care medical wards in Angers University hospital (France) were included in this study using an observational prospective cohort design. Within 24 hours after admission of older inpatients, nurses performed a bedside clinical assessment. Participants were separated into non-fallers and fallers (i.e.; ≥1 fall during hospitalization stay). The analysis was conducted using three feed forward ANNs (multilayer perceptron [MLP], averaged neural network, and neuroevolution of augmenting topologies [NEAT]). Seventy-three (8.6%) participants fell at least once during their hospital stay. ANNs showed a high specificity, regardless of which ANN was used, and the highest value reported was with MLP (99.8%). In contrast, sensitivity was lower, with values ranging between 98.4 to 14.8%. MLP had the highest accuracy (99.7). Performance criteria for fall prediction resulting from a bedside nursing assessment and an ANNs analysis was associated with a high specificity but a low sensitivity, suggesting that this combined approach should be used more as a diagnostic test than a screening test when considering older inpatients in acute care medical ward.

Evaluation of left ventricular function by bedside ultrasound in acute toxic myocarditis.

PubMed

Brown, Cara; Budhram, Gavin

2013-10-01

Myocarditis can be difficult to diagnose in the Emergency Department (ED) due to the lack of classic symptoms and the wide variation in presentations. Poor cardiac contractility is a common finding in myocarditis and can be evaluated by bedside ultrasound. To demonstrate the utility of fractional shortening measurements as an estimation of left ventricular function during bedside cardiac ultrasound evaluation in the ED. A 54-year-old man presented to the ED complaining of 3 days of chest tightness, palpitations, and dyspnea, as well as persistent abdominal pain and vomiting. An electrocardiogram (ECG) showed sinus tachycardia with presumably new ST-segment elevation and signs of an incomplete right bundle branch block. A bedside echocardiogram was performed by the emergency physician that showed poor left ventricular function by endocardial fractional shortening measurements. On further questioning, the patient revealed that for the past 2 weeks he had been regularly huffing a commercially available compressed air duster. Based on these history and examination findings, the patient was given a presumptive diagnosis of toxic myocarditis. A follow-up echocardiogram approximately 7 weeks later demonstrated resolution of the left ventricular systolic dysfunction and his ECG findings normalized. Cardiac ultrasound findings of severely reduced global function measured by endocardial fractional shortening were seen in this patient and supported the diagnosis of myocarditis. Endocardial fractional shortening is a useful means of easily evaluating and documenting left ventricular function and can be performed at the bedside in the ED. Copyright © 2013 Elsevier Inc.

Physician burnout is common and associated with significant consequences for physicians and patients. One mechanism to combat burnout is to enhance meaning in work. To provide a trainee perspective on how meaning in work can be enhanced in the clinical learning environment through individual, program, and institutional efforts. "Back to Bedside" resulted from an appreciative inquiry exercise by 37 resident and fellow members of the ACGME's Council of Review Committee Residents (CRCR), which was guided by the memoir When Breath Becomes Air by Paul Kalanithi. The exercise was designed to (1) discover current best practices in existing learning environments; (2) dream of ideal ways to enhance meaning in work; (3) design solutions that move toward this optimal environment; and (4) support trainees in operationalizing innovative solutions. Back to Bedside consists of 5 themes for how the learning environment can enhance meaning in daily work: (1) more time at the bedside, engaged in direct patient care, dialogue with patients and families, and bedside clinical teaching; (2) a shared sense of teamwork and respect among multidisciplinary health professionals and trainees; (3) decreasing the time spent on nonclinical and administrative responsibilities; (4) a supportive, collegial work environment; and (5) a learning environment conducive to developing clinical mastery and progressive autonomy. Participants identified actions to achieve these goals. A national, multispecialty group of trainees developed actionable recommendations for how clinical learning environments can be improved to combat physician burnout by fostering meaning in work. These improvements can be championed by trainees.

The robotic surgical platform is being utilized by a growing number of hospitals across the country, including academic medical centers. Training programs are tasked with teaching their residents how to utilize this technology. To this end, we have developed and implemented a robotic surgical curriculum, and share our initial experience here. Our curriculum was implemented for all General Surgical residents for the academic year 2014-2015. The curriculum consisted of online training, readings, bedside training, console simulation, participating in ten cases as bedside first assistant, and operating at the console. 20 surgical residents were included. Residents were provided the curriculum and notified the department upon completion. Bedside assistance and operative console training were completed in the operating room through a mix of biliary, foregut, and colorectal cases. During the fiscal years of 2014 and 2015, there were 164 and 263 robot-assisted surgeries performed within the General Surgery Department, respectively. All 20 residents completed the online and bedside instruction portions of the curriculum. Of the 20 residents trained, 13/20 (65 %) sat at the Surgeon console during at least one case. Utilizing this curriculum, we have trained and incorporated residents into robot-assisted cases in an efficient manner. A successful curriculum must be based on didactic learning, reading, bedside training, simulation, and training in the operating room. Each program must examine their caseload and resident class to ensure proper exposure to this platform.

At some academic hospitals, medical procedure services are being developed to provide supervision for residents performing bedside procedures in hopes of improving patient safety and resident education. There is limited knowledge of the impact of such services on procedural complication rates and resident procedural training opportunities. To determine the impact of a medical procedure service (MPS) on patient safety and resident procedural training opportunities. Retrospective cohort analysis comparing characteristics and outcomes of procedures performed by the MPS versus the primary medical service. Consecutive adults admitted to internal medicine services at a large academic hospital who underwent a bedside medical procedure (central venous catheterization, thoracentesis, paracentesis, lumbar puncture) between 1 July 2010 and 31 December 2011. The primary outcome was a composite rate of major complications. Secondary outcomes included resident participation in bedside procedures and use of "best practice" safety process measures. We evaluated 1,707 bedside procedures (548 by the MPS, 1,159 by the primary services). There were no differences in the composite rate of major complications (1.6 % vs. 1.9 %, p = 0.71) or resident participation in bedside procedures (57.0 % vs. 54.3 %, p = 0.31) between the MPS and the primary services. Procedures performed by the MPS were more likely to be successfully completed (95.8 % vs. 92.8 %, p = 0.02) and to use best practice safety process measures, including use of ultrasound guidance when appropriate (96.8 % vs. 90.0 %, p = 0.0004), avoidance of femoral venous catheterization (89.5 vs. 82.7 %, p = 0.02) and involvement of attending physicians (99.3 % vs. 57.0 %, p < 0.0001). Although use of a MPS did not significantly affect the rate of major complications or resident opportunities for training in bedside procedures, it was associated with increased use of best practice safety process measures.

Teaching cardiac auscultation to trainees in internal medicine and family practice: Does it work?

2004-01-01

Background The general proficiency in physical diagnostic skills seems to be declining in relation to the development of new technologies. The few studies that have examined this question have invariably used recordings of cardiac events obtained from patients. However, this type of evaluation may not correlate particularly well with bedside skills. Our objectives were 1) To compare the cardiac auscultatory skills of physicians in training with those of experienced cardiologists by using real patients to test bedside diagnostic skills. 2) To evaluate the impact of a five-month bedside cardiac auscultation training program. Methods 1) In an academic primary care center, 20 physicians (trainees in internal medicine and family practice) and two skilled academic cardiologists listened to 33 cardiac events in 13 patients directly at bedside and identified the cardiac events by completing an open questionnaire. Heart sounds, murmurs and diagnosis were determined beforehand by an independent skilled cardiologist and were validated by echocardiography. Thirteen primary cardiologic diagnoses were possible. 2) Ten of the physicians agreed to participate in a course of 45-minute sessions once a week for 5 months. After the course they listened again to the same patients (pre/post-interventional study). Results 1) The experts were the most skillful, achieving 69% recognition of heart sounds and murmurs and correct diagnoses in 62% of cases. They also heard all of the diastolic murmurs. The residents heard only 40% of the extra heart sounds and made a correct diagnosis in 24% of cases. 2) After the weekly training sessions, their mean percentage for correct diagnosis was 35% [an increase of 66% (p < 0.05)]. Conclusions The level of bedside diagnostic skills in this relatively small group of physicians in training is indeed low, but can be improved by a course focusing on realistic bedside teaching.

The performances of K-AST in 26 patients (21 males, 5 females; mean age 65.42±17.31 years) with stroke (23 ischemic, 3 hemorrhagic) were videotaped. To test the reliability and validity of K-AST, the recorded performances were assessed by two physiatrists and two occupational therapists twice at a 1-week interval. The patient performances at admission in Korean version of Mini-Mental State Examination (K-MMSE), self-care and transfer categories of Functional Independence Measure (FIM), and motor praxis area of Loewenstein Occupational Therapy Cognitive Assessment, the second edition (LOTCA-II) were also evaluated. Scores of motor praxis area of LOTCA-II was used to assess the validity of K-AST. Inter-rater reliabilities were 0.983 (p<0.001) at the first assessment and 0.982 (p<0.001) at the second assessment. For intra-rater (test-retest) reliabilities, the values of four raters were 0.978 (p<0.001), 0.957 (p<0.001), 0.987 (p<0.001), and 0.977 (p<0.001). K-AST showed significant correlation (r=0.758, p<0.001) with motor praxis area of LOTCA-II test. K-AST also showed positive correlations with the total FIM score (r=0.694, p<0.001), the selfcare category of FIM (r=0.705, p<0.001) and the transfer category of FIM (r=653, p<0.001). K-AST is a reliable and valid test for bedside screening of apraxia.

The current practice of physical diagnosis is dependent on physician skills and biases, inductive reasoning, and time efficiency. Although the clinical utility of echocardiography is well known, few data exist on how to integrate 2-dimensional screening "quick-look" ultrasound applications into a novel, modernized cardiac physical examination. We discuss the evidence basis behind ultrasound "signs" pertinent to the cardiovascular system and elemental in synthesis of bedside diagnoses and propose the application of a brief cardiac limited ultrasound examination based on these signs. An ultrasound-augmented cardiac physical examination can be taught in traditional medical education and has the potential to improve bedside diagnosis and patient care. © 2015 by the American Institute of Ultrasound in Medicine.

Birth, death, and resurrection of the physical examination: clinical and academic perspectives on bedside diagnosis.

PubMed Central

Peixoto, A. J.

2001-01-01

The physical examination has a historically prominent role in medical practice, being an important tool in diagnosis and in developing rapport with patients. Yet, physicians have lost bedside skills in recent years, with increasing use of technology at the expense of time spent with the patient. This is concerning, especially in the present era of cost-containment in health care. Approaches to improve bedside diagnosis skills include increased emphasis on instruction in physical examination during medical school and postgraduate training, and careful scrutiny of physical examination techniques, with formal evaluation of their accuracy and reproducibility. Only through education and research will the physical examination recover its central role in the clinical encounter. PMID:11697480

Rates of burnout, mental illness, and suicide are disproportionately elevated among physicians, and surgical specialists, including otolaryngologists, are at even higher risk for professional burnout. These trends have been identified at both the trainee and attending level. To combat resident burnout, the Accreditation Council for Graduate Medical Education (ACGME) Council of Review Committee Residents (CRCR) designed the Back to Bedside Initiative, the goals of which are to foster meaning in the learning environment and to help trainees to engage more deeply with patients. Two funded Back to Bedside proposals involve otolaryngology training programs. Herein, we discuss these 2 approaches in an effort to foster additional novel resident wellness initiatives and awareness thereof across our subspecialty.

Graded assessment and classification of impaired temperature sensibility in patients with diabetic polyneuropathy.

PubMed Central

Hansson, P; Lindblom, U; Lindström, P

1991-01-01

Thermal sensibility was quantitatively assessed in the feet of 46 diabetic patients. In subjects with sensibility deficits the perception threshold for warmth or cold, or of heat pain, was either increased or lost. Four stages of impaired thermal sensibility were defined, and a classification of dysfunction is proposed which could be useful in routine clinical examination of patients with diabetic polyneuropathy. The classification of impaired thermal sensibility correlated significantly with the results of a bedside screening examination aimed at describing the severity of the polyneuropathy in terms of its regional extent.

A system for rapid analysis of the femoral blood velocity waveform at the bedside.

PubMed

Capper, W L; Amoore, J N; Clifford, P C; Immelman, E J; Harries-Jones, E P

1986-01-01

The shape of the arterial blood velocity waveform varies with atherosclerotic disease and several methods of quantifying the shape in order to predict the severity of the disease have been described. These methods include pulsatility index, the Laplace transform method, and principal component analysis. This paper describes the development of a system which allows the operator to acquire, display, and store waveforms from each limb and then to quantify the waveforms at the bedside within a few minutes. The system includes a 10 MHz bi-directional Doppler unit, an instantaneous mean frequency processor, and an Apple II microcomputer fitted with an accelerator card. Both the Laplace transform parameters and the pulsatility index are computed and each result is printed in tabular form together with the averaged results of five waveforms from each limb. The printout is suitable for inclusion in the patient's folder. In initial clinical studies Laplace transform analysis exhibited a good correlation with aorto-iliac stenosis as assessed angiographically (R = 0.73 P less than 0.001 t test).

Technology for enhancing chest auscultation in clinical simulation.

PubMed

Ward, Jeffrey J; Wattier, Bryan A

2011-06-01

The ability to use an acoustic stethoscope to detect lung and/or heart sounds, and then to then communicate one's interpretation of those sounds is an essential skill for many medical professionals. Interpretation of lung and heart sounds, in the context of history and other examination findings, often aids the differential diagnosis. Bedside assessment of changing auscultation findings may also guide treatment. Learning lung and heart auscultation skills typically involves listening to pre-recorded normal and adventitious sounds, often followed by laboratory instruction to guide stethoscope placement, and finally correlating the sounds with the associated pathophysiology and pathology. Recently, medical simulation has become an important tool for teaching prior to clinical practice, and for evaluating bedside auscultation skills. When simulating cardiovascular or pulmonary problems, high-quality lung and heart sounds should be able to accurately corroborate other findings such as vital signs, arterial blood gas values, or imaging. Digital audio technology, the Internet, and high-fidelity simulators have increased opportunities for educators and learners. We review the application of these technologies and describe options for reproducing lung and heart sounds, as well as their advantages and potential limitations.

Concerned with the quality of internal medicine training, many leaders in the field assembled to assess the state of the residency, evaluate the decline in interest in the specialty, and create a framework for invigorating the discipline. Although many external factors are responsible, we also found ourselves culpable: allowing senior role models to opt out of important training activities, ignoring a progressive atrophy of bedside skills, and focusing on lock-step curricula, lectures, and compiled diagnostic and therapeutic strategies. The group affirmed its commitment to a vision of internal medicine rooted in science and learned with mentors at the bedside. Key factors for new emphasis include patient-centered small group teaching, greater incorporation of clinical epidemiology and health services research, and better schedule control for trainees. Because previous proposals were weakened by lack of evidence, we propose to organize the Cooperative Educational Studies Group, a pool of training programs that will collect a common data set describing their programs, design interventions to be tested rigorously in multi-methodological approaches, and at the same time produce knowledge about high-quality practice.

The Accutrend sensor glucose analyzer may not be adequate in bedside testing for neonatal hypoglycemia.

PubMed

Rosenthal, Mark; Ugele, Bernhard; Lipowsky, Gerd; Küster, Helmut

2006-02-01

The aim of this prospective observational study was to compare a bedside test with the reference laboratory method in routine postnatal glucose monitoring. Term newborns with increased risk or clinical signs of hypoglycemia were screened with a bedside test. In case of a glucose value below 2.25 mmol/L, a second blood sample was taken and a duplicate glucose measurement done in the laboratory using a bedside test (Accutrend sensor) and the reference laboratory method (hexokinase method) at the same time and from the same sample. From 110 term newborns, 122 blood samples were obtained for duplicate measurements (median 1.69 mmol/L, SD 0.45 mmol/L). Of these 122, Accutrend correctly identified 97% as being <2.25 mmol/L by the laboratory method. A Bland-Altman plot revealed a mean underestimation of the Accutrend of only -0.09 mmol/L. However, due to high scattering, the maximal over- and underestimation was 0.89 and 1.39 mmol/L, respectively. Only 75% of the results from the Accutrend were within +/-20% of the result of the laboratory method. If the cut-off for low glucose concentrations was set 0.6 mmol/L higher for the bedside test as compared to the laboratory method, all patients except one would have been correctly identified as hypoglycemic. When using the Accutrend sensor, single infants with even marked hypoglycemia might be missed. Some delay in receiving accurate measurements might be more helpful for clinical decisions and long-term outcome than immediate but potentially misleading results.

Bedside teaching and the acquisition of practical skills in mid-sixteenth-century Padua.

PubMed

Stolberg, Michael

2014-10-01

Very little is known to this point about the practical skills which sixteenth-century physicians needed and applied at the bedside and even less about how these skills were taught to students. Drawing on student notebooks and on printed collections of consilia by Padua professors, this paper outlines the different settings in which case-centered and, more specifically, bedside teaching was imparted in mid-sixteenth-century Padua. It describes the range of diagnostic and therapeutic skills that students acquired thanks to this hands-on training at the patient's bedside, from uroscopy and feeling the pulse to the manual exploration of the patient's abdomen, which, historians have wrongly believed, physicians performed very rarely or not at all, and surgical skills. Taking a closer look, more specifically, at the role of teaching in the Hospital of San Francesco in Padua, the paper provides evidence that not only Giovanna Battista da Monte but also at least one other mid-sixteenth-century professor, Antonio Fracanzani, made systematic use of the teaching opportunities which the hospital offered. Ultimately, the paper will argue that clinical teaching in the hospital did not differ fundamentally from forms of bedside teaching in the patients' homes, however. Both became increasingly popular in Padua and elsewhere at the time, reflecting a growing appreciation for the practical and sensory skills which future physicians needed in addition to theoretical learning if they hoped to be successful in the highly contested early modern medical marketplace. © The Author 2013.

A bedside toxicology consult service may improve clinical care, facilitate patient clearance and disposition, and result in potential cost savings for poisoning exposures. Despite this, there is scant data regarding economic feasibility for such a service. Previously published information suggests low hourly reimbursement at approximately $26.00/h at the bedside for toxicology consultations. A bedside toxicology consultant service was initiated in 2011. Coverage was available 24 h a day for 50 out of 52 weeks. Bedside rounding on toxicology consult patients was available 6/7 days per week. The practice is associated with >800 bed teaching institution in a large upstate NY region with elements of urban and suburban practice. Demographic and billing data was collected for all patients consulted upon from July 1, 2011 to June 31, 2012. In charges of $514,941 were generated during the period of data collection. Monthly average was $42,912. Net reimbursement of charges was 29 % of overall charges at $147,792. In terms of total encounters, net collection rate in which something was reimbursed or "paid" against charges for that encounter was 82.6 % of all encounters at 999/1,210. Average encounter time for inpatients, including critical care, was 1.05 h, and the average time spent for outpatients was 1.18 h. Reimbursement rates appear higher than previously reported. Revenue generated from reimbursement from toxicology consultation can result in recouping a substantial portion of a toxicologist's salary or potentially fund fellowship positions and salaries or toxicology division infrastructure.

This paper presents family bedside orientations, an innovative bedside peer support model for families of paediatric patients piloted in one unit at the Stollery Children's Hospital in Edmonton, Alberta. The model invites family members of former patients back to the hospital as volunteer peer mentors responsible for meeting one-on-one with current inpatient families to provide a listening presence, discuss patient safety practices and encourage families to participate in their child's care. Using qualitative and quantitative data collection methods, the model was evaluated over 1 year (December 2014 to December 2015). Data sources included peer mentor field notes (from 163 visits) detailing the number of family bedside orientations completed by peer mentors and how they interacted with families, as well as post-visit family (n=35) surveys, Hospital-Child Inpatient Experience Survey data, peer mentor (n=6) questionnaires, focus groups with unit staff (n=10) and interviews with members of the project leadership team (n=5). Our findings indicated that family bedside orientations became an established practice in the pilot unit and positively impacted family care experiences. We attribute these successes to championing and support from unit staff and our multidisciplinary project leadership team. We discuss how our team addressed family privacy and confidentiality while introducing peer mentors in the unit. We also highlight strategies used to integrate peer mentors as part of the staff team and enhance peer support culture in the pilot unit. Practical considerations for implementing this model in other paediatric environments are provided.

Surgical procedures performed at the bedside in the neonatal intensive care unit (NICU) at The Children's Hospital of Philadelphia were documented using paper anesthesia records in contrast to the operating rooms, where an anesthesia information management system (AIMS) was used for all cases. This was largely because of logistical problems related to connecting cables between the bedside monitors and our portable AIMS workstations. We implemented an AIMS for documentation in the NICU using wireless adapters to transmit data from bedside monitoring equipment to a portable AIMS workstation. Testing of the wireless AIMS during simulation in the presence of an electrosurgical generator showed no evidence of interference with data transmission. Thirty NICU surgical procedures were documented via the wireless AIMS. Two wireless cases exhibited brief periods of data loss; one case had an extended data gap because of adapter power failure. In comparison, in a control group of 30 surgical cases in which wired connections were used, there were no data gaps. The wireless AIMS provided a simple, unobtrusive, portable alternative to paper records for documenting anesthesia records during NICU bedside procedures.

A Waveform Archiving System for the GE Solar 8000i Bedside Monitor.

2018-01-01

Our objective was to develop, deploy, and test a data-acquisition system for the reliable and robust archiving of high-resolution physiological waveform data from a variety of bedside monitoring devices, including the GE Solar 8000i patient monitor, and for the logging of ancillary clinical and demographic information. The data-acquisition system consists of a computer-based archiving unit and a GE Tram Rac 4A that connects to the GE Solar 8000i monitor. Standard physiological front-end sensors connect directly to the Tram Rac, which serves as a port replicator for the GE monitor and provides access to these waveform signals through an analog data interface. Together with the GE monitoring data streams, we simultaneously collect the cerebral blood flow velocity envelope from a transcranial Doppler ultrasound system and a non-invasive arterial blood pressure waveform along a common time axis. All waveform signals are digitized and archived through a LabView-controlled interface that also allows for the logging of relevant meta-data such as clinical and patient demographic information. The acquisition system was certified for hospital use by the clinical engineering team at Boston Medical Center, Boston, MA, USA. Over a 12-month period, we collected 57 datasets from 11 neuro-ICU patients. The system provided reliable and failure-free waveform archiving. We measured an average temporal drift between waveforms from different monitoring devices of 1 ms every 66 min of recorded data. The waveform acquisition system allows for robust real-time data acquisition, processing, and archiving of waveforms. The temporal drift between waveforms archived from different devices is entirely negligible, even for long-term recording.

Delays in diagnosis occur with complex regional pain syndrome (CRPS). We define and prospectively demonstrate that novel bedside tests measuring body perception disruption can identify patients with CRPS postfracture. The objectives of our study were to define and validate 4 bedside tests, to identify the prevalence of positive tests in patients with CRPS and other chronic pain conditions, and to assess the clinical utility (sensitivity, specificity, positive predictive value, negative predictive value) for identifying CRPS within a Fracture cohort. This was a single UK teaching hospital prospective cohort study with 313 recruits from pain-free volunteers and patients with chronic pain conditions.Four novel tests were Finger Perception (FP), Hand Laterality identification (HL), Astereognosis (AS), and Body Scheme (BS) report. Five questionnaires (Brief Pain Inventory, Upper Extremity Functional Index, Lower Extremity Functional Index, Neglect-like Symptom Questionnaire, Hospital Anxiety and Depression Score) assessed the multidimensional pain experience. FP and BS were the best performing tests. Prospective monitoring of fracture patients showed that out of 7 fracture patients (total n=47) who had both finger misperception and abnormal BS report at initial testing, 3 developed persistent pain with 1 having a formal diagnosis of CRPS. Novel signs are reliable, easy to perform, and present in chronic pain patients. FP and BS have significant clinical utility in predicting persistent pain in a fracture group thereby allowing targeted early intervention.

Visions and reality: the idea of competence-oriented assessment for German medical students is not yet realised in licensing examinations

Objective: Competence orientation, often based on the CanMEDS model, has become an important goal for modern curricula in medical education. The National Competence Based Catalogue of Learning Objectives for Undergraduate Medical Education (NKLM) has been adopted in Germany. However, it is currently unknown whether the vision of competence orientation has also reached the licensing examination procedures. Methods: Therefore, a prospective, descriptive, single-centre, exemplary study design was applied to evaluate 4051 questions/tasks (from 28 examiners at 7 two-day licensing oral-practical exams) for undergraduate medical students at the University of Ulm. The oral and practical questions/tasks as well as the real bedside assessment were assigned to specific competence roles (NKLM section I), categories (NKLM section II) and taxonomy levels of learning domains. Results: Numerous questions/tasks were set per candidate (day 1/2: 70±24/86±19 questions) in the licensing oral-practical exam. Competence roles beyond the “medical expert” were scarcely considered. Furthermore, practical and communication skills at the bedside were hardly addressed (less than 3/15 min). Strikingly, there was a significant predominance of questions with a low-level taxonomy. Conclusions: The data indicate a misalignment of competence-oriented frameworks and the “real world” licensing practical-oral medical exam, which needs improvement in both evaluation and education processes.

To propose a new methodology based on single-trial analysis for detecting residual response to command with EMG in patients with disorders of consciousness (DOC), overcoming the issue of trial dependency and decreasing the influence of a patient's fluctuation of vigilance or arousal over time on diagnostic accuracy. Forty-five patients with DOC (18 with vegetative/unresponsive wakefulness syndrome [VS/UWS], 22 in a minimally conscious state [MCS], 3 who emerged from MCS [EMCS], and 2 with locked-in syndrome [LIS]) and 20 healthy controls were included in the study. Patients were randomly instructed to either move their left or right hand or listen to a control command ("It is a sunny day") while EMG activity was recorded on both arms. Differential EMG activity was detected in all MCS cases displaying reproducible response to command at bedside on multiple assessments, even though only 6 of the 14 individuals presented a behavioral response to command on the day of the EMG assessment. An EMG response was also detected in all EMCS and LIS patients, and 2 MCS patients showing nonreflexive movements without command following at the bedside. None of the VS/UWS presented a response to command with this method. This method allowed us to reliably distinguish between different levels of consciousness and could potentially help decrease diagnostic errors in patients with motor impairment but presenting residual motor activity. © 2016 American Academy of Neurology.

Functional neuroimaging is becoming a valuable tool in cognitive research and clinical applications. The clinical context brings specific constraints that include the requirement of a high channel count to cover the whole head, high sensitivity for single event detection, and portability for long-term bedside monitoring. For epilepsy and stroke monitoring, the combination of electroencephalography (EEG) and functional near-infrared spectroscopy (NIRS) is expected to provide useful clinical information, and efforts have been deployed to create prototypes able to simultaneously acquire both measurement modalities. However, to the best of our knowledge, existing systems lack portability, NIRS sensitivity, or have low channel count. We present a battery-powered, portable system with potentially up to 32 EEG channels, 32 NIRS light sources, and 32 detectors. Avalanche photodiodes allow for high NIRS sensitivity and the autonomy of the system is over 24 h. A reduced channel count prototype with 8 EEG channels, 8 sources, and 8 detectors was tested on phantoms. Further validation was done on five healthy adults using a visual stimulation protocol to detect local hemodynamic changes and visually evoked potentials. Results show good concordance with literature regarding functional activations and suggest sufficient performance for clinical use, provided some minor adjustments were made.

Reliability and Validity of Bedside Version of Persian WAB (P-WAB-1).

2014-10-01

In this study, we reported the reliability and validity of Bedside version of Persian WAB (P-WAB-1) adapted from Western Aphasia Battery (WAB-R) (1,2). P-WAB-1 is a clinical linguistic measuring tool to determine severity and type of aphasia in brain damaged patients based on Aphasia Quotient (AQ) as a functional measure. For the purposes of a quick clinical screening of aphasia in Persian, we adapted the bedside version of WAB-R to assess the performance of Persian aphasic patients. The data we reported on adaptation, validity and reliability of P-WAB-1 are based on faithful translation and criterion validity ratio (CVR) taken from the expert panel and the performance of 60 consecutive brain damaged patients referred to different university clinics for rehabilitation and 30 healthy subjects as norms and 40 age-matched epileptic patients as the control group. Based on the results of this study, P-WAB-1 has internal consistency (a=0.71) and test-retest reliability (r=.65 P<0.001) and the subtests are sensitive enough to contribute to Aphasia Quotient (AQ) as a functional measure of severity of aphasia in Iranian brain damaged patients. Based on AQ results, our aphasic patients were classified into four distinct groups of severity. P-WAB-1 is the first clinical linguistic test to determine severity of aphasia based on an operational index and can be considered as a valid baseline for screening and diagnosis of aphasia among Persian speaking brain damaged patients. This study is the initial step on adaptation of different versions of WAB-R to measure the severity of aphasia using AQ, LQ and CQ as operational measures and to classify Persian speaking aphasic patients into different types.

Although overall paediatric septic shock mortality is decreasing, refractory septic shock (RSS) is still associated with high mortality. A definition for RSS is urgently needed to facilitate earlier identification and treatment. We aim to establish a European society of paediatric and neonatal intensive care (ESPNIC) experts' definition of paediatric RSS. We conducted a two-round Delphi study followed by an observational multicentre retrospective study. One hundred and fourteen paediatric intensivists answered a clinical case-based, two-round Delphi survey, identifying clinical items consistent with RSS. Multivariate analysis of these items in a development single-centre cohort (70 patients, 30 % mortality) facilitated development of RSS definitions based on either a bedside or computed severity score. Both scores were subsequently tested in a validation cohort (six centres, 424 patients, 11.6 % mortality). From the Delphi process, the draft definition included evidence of myocardial dysfunction and high blood lactate levels despite high vasopressor treatment. When assessed in the development population, each item was independently associated with the need for extracorporeal life support (ECLS) or death. Resultant bedside and computed septic shock scores had high discriminative power against the need for ECLS or death, with areas under the receiver operating characteristics curve of 0.920 (95 % CI 0.89-0.94), and 0.956 (95 % CI 0.93-0.97), respectively. RSS defined by a bedside score equal to or higher than 2 and a computed score equal to or higher than 3.5 was associated with a significant increase in mortality. This ESPNIC definition of RSS accurately identifies children with the most severe form of septic shock.

Imaging Neuroinflammation – from Bench to Bedside

PubMed Central

Pulli, Benjamin; Chen, John W

2014-01-01

Neuroinflammation plays a central role in a variety of neurological diseases, including stroke, multiple sclerosis, Alzheimer’s disease, and malignant CNS neoplasms, among many other. Different cell types and molecular mediators participate in a cascade of events in the brain that is ultimately aimed at control, regeneration and repair, but leads to damage of brain tissue under pathological conditions. Non-invasive molecular imaging of key players in the inflammation cascade holds promise for identification and quantification of the disease process before it is too late for effective therapeutic intervention. In this review, we focus on molecular imaging techniques that target inflammatory cells and molecules that are of interest in neuroinflammation, especially those with high translational potential. Over the past decade, a plethora of molecular imaging agents have been developed and tested in animal models of (neuro)inflammation, and a few have been translated from bench to bedside. The most promising imaging techniques to visualize neuroinflammation include MRI, positron emission tomography (PET), single photon emission computed tomography (SPECT), and optical imaging methods. These techniques enable us to image adhesion molecules to visualize endothelial cell activation, assess leukocyte functions such as oxidative stress, granule release, and phagocytosis, and label a variety of inflammatory cells for cell tracking experiments. In addition, several cell types and their activation can be specifically targeted in vivo, and consequences of neuroinflammation such as neuronal death and demyelination can be quantified. As we continue to make progress in utilizing molecular imaging technology to study and understand neuroinflammation, increasing efforts and investment should be made to bring more of these novel imaging agents from the “bench to bedside.” PMID:25525560

Despite evidence supporting restrictive red blood cell (RBC) transfusion thresholds and the associated clinical practice guidelines, clinical practice has been slow to change in the intensive care unit (ICU). Our aim was to identify barriers to conservative transfusion practice adherence. A mixed-methods study involving observation of prescriber (i.e., physicians, physician assistants, nurse practitioners) and bedside nurse daily bedside rounds, provider survey, and medical record abstraction was conducted in one cardiac surgical ICU (CSICU) and one surgical ICU (SICU) in an academic hospital in Baltimore, Maryland. Of 52 patient encounters observed during bedside rounds, 38 (73%) involved patients without evidence of active bleeding or cardiac ischemia. Surveys were completed by 52 (93%) of the 56 providers participating in rounds. Prescribers in the CSICU and SICU (87 and 90%, respectively) indicated the ideal pretransfusion hemoglobin (Hb) to be not more than 7 g/dL in nonbleeding and/or nonischemic patients compared to a minority of nurses (8% [p = 0.002] and 42% [p = 0.015], respectively). Prescribers and nurses in both ICUs overestimated the typical pretransfusion Hb in their units (CSICU, p < 0.001; SICU, p = 0.019). During rounds, providers infrequently explicitly discussed Hb monitoring or transfusion thresholds (33%) despite most (60%) reporting significant variation in transfusion thresholds between individual prescribers. Our study identified several provider and system barriers to evidence-based transfusion practices including knowledge differences, overly optimistic estimates of current practice, and heterogeneous transfusion practice in each ICU. Further work is necessary to develop targeted interventions to improve evidence-based RBC transfusion practices. © 2014 AABB.

The aim of the study was to introduce and evaluate the compliance to documentation of situation, background, assessment, recommendation (SBAR) form. Twenty nurses involved in active bedside care were selected by simple random sampling. Use of SBAR was illustrated thru self-instructional module (SIM). Content validity and reliability were established. The situation, background, assessment, recommendation (SBAR) form was disseminated for use in a clinical setting during shift handover. A retrospective audit was undertaken at 1 st week (A1) and 16 th week (A2), post introduction of SIM. Nurse's opinion about the SBAR form was also captured. Majority of nurses were females (65%) in the age group 21-30 years (80%). There was a significant association ( P = 0.019) between overall audit scores and graduate nurses. Significant improvement ( P = 0.043) seen in overall scores between A1 (mean: 23.20) and A2 (mean: 24.26) and also in "Situation" domain ( P = 0.045) as compared to other domains. There was only a marginal improvement in documentation related to patient's allergies and relevant past history (7%) while identifying comorbidities decreased by 40%. Only 70% of nurses had documented plan of care. Most (76%) of nurses expressed that SBAR form was useful, but 24% nurses felt SBAR documentation was time-consuming. The assessment was easy (53%) to document while recommendation was the difficult (53%) part. SBAR technique has helped nurses to have a focused and easy communication during transition of care during handover. Importance and relevance of capturing information need to be reinforced. An audit to look for reduced number of incidents related to communication failures is essential for long-term evaluation of patient outcomes. Use of standardized SBAR in nursing practice for bedside shift handover will improve communication between nurses and thus ensure patient safety.

Despite their potential interest for clinical management, measurements of respiratory mechanics in patients with acute respiratory distress syndrome (ARDS) are seldom performed in routine practice. We introduced a systematic assessment of respiratory mechanics in our clinical practice. After the first year of clinical use, we retrospectively assessed whether these measurements had any influence on clinical management and physiological parameters associated with clinical outcomes by comparing their value before and after performing the test. The respiratory mechanics assessment constituted a set of bedside measurements to determine passive lung and chest wall mechanics, response to positive end-expiratory pressure, and alveolar derecruitment. It was obtained early after ARDS diagnosis. The results were provided to the clinical team to be used at their own discretion. We compared ventilator settings and physiological variables before and after the test. The physiological endpoints were oxygenation index, dead space, and plateau and driving pressures. Sixty-one consecutive patients with ARDS were enrolled. Esophageal pressure was measured in 53 patients (86.9%). In 41 patients (67.2%), ventilator settings were changed after the measurements, often by reducing positive end-expiratory pressure or by switching pressure-targeted mode to volume-targeted mode. Following changes, the oxygenation index, airway plateau, and driving pressures were significantly improved, whereas the dead-space fraction remained unchanged. The oxygenation index continued to improve in the next 48 h. Implementing a systematic respiratory mechanics test leads to frequent individual adaptations of ventilator settings and allows improvement in oxygenation indexes and reduction of the risk of overdistention at the same time. The present study involves data from our ongoing registry for respiratory mechanics (ClinicalTrials.gov identifier: NCT02623192 . Registered 30 July 2015).

To improve communication during daily cardiac ICU multidisciplinary rounds. Quality improvement methodology. Twenty-five-bed cardiac ICUs in an academic free-standing pediatric hospital. All patients admitted to the cardiac ICU. Implementation of visual display of patient daily goals through a write-down and read-back process. The Rounds Effectiveness Assessment and Communication Tool was developed based on the previously validated Patient Knowledge Assessment Tool to evaluate comprehension of patient daily goals. Rounds were assessed for each patient by the bedside nurse, nurse practitioner or fellow, and attending physician, and answers were compared to determine percent agreement per day. At baseline, percent agreement for patient goals was only 62%. After initial implementation of the daily goal write-down/read-back process, which was written on paper by the bedside nurse, the Rounds Effectiveness Assessment and Communication Tool survey revealed no improvement. With adaptation of the intervention so goals were written on whiteboards for visual display during rounds, the percent agreement improved to 85%. Families were also asked to complete a survey (1-6 Likert scale) of their satisfaction with rounds and understanding of daily goals before and after the intervention. Family survey results improved from a mean of 4.6-5.7. Parent selection of the best possible score for each question was 19% at baseline and 75% after the intervention. Visual display of patient daily goals via a write-down/read-back process improves comprehension of goals by all team members and improves parent satisfaction. The daily goal whiteboard facilitates consistent development of a comprehensive plan of care for each patient, fosters goal-directed care, and provides a checklist for providers and parents to review throughout the day.

'Bedside assessment' of acute hantavirus infections and their possible classification into the spectrum of haemophagocytic syndromes.

Hantavirus infections, recently renamed 'hantavirus fever' (HTVF), belong to the most common but also most underestimated zoonoses in the world. A small number of reports described the so-called 'lipid paradox' in HTVF, i.e. the striking contrast between a very low serum total cholesterol and/or high-density lipoprotein cholesterol (HDLc), and a paradoxical concomitant hypertriglyceridaemia. In a prospective study, with patients being their own control after illness, we wanted to verify if this quick and easy 'bedside test' was robust enough to warrant a preliminary diagnosis of acute kidney injury (AKI) caused by HTVF. The study cohort consisted of 58 Belgian cases (mean age 44 years), admitted with varying degrees of AKI and of thrombocytopaenia, both characteristic for presumptive HTVF. All cases were sero-confirmed as having acute HTVF. At or shortly after hospital admission, a significant (p < 0.001) decrease of total cholesterol and HDLc was found in comparison with normalised levels in the same cohort, quantified a few days after spontaneous AKI recovery. Conversely, fasting triglyceride levels during HTVF infection were significantly (p < 0.001) higher during illness than after recovery. This 'lipid paradox' was most outspoken in severe HTVF cases, often accompanying, or even predicting, major kidney or lung complications. Thus, this 'bedside assessment' seems to hold even promise for presumptive diagnosis of more severe so-called 'hantavirus cardio-pulmonary syndrome' (HCPS) cases, mostly described hitherto in the New World. In more severe AKI cases, the mean total cholesterol was significantly lower (p = 0.02) than in milder cases, i.e. cases with peak serum creatinine levels of < 1.5 mg/dL. Thrombocytopaenia, generally accepted as the severity index in HTVF, appeared, moreover, significantly correlated with serum levels of total cholesterol (R = 0.52, p < 0.001) and with serum levels of HDLc (R = 0.45, p < 0.01). A link with the novel clinical entity of haemophagocytic syndromes, also characterised by manifest hypertriglyceridaemia, is discussed.

Bedside inferior vena cava filter (IVCF) placement by intravascular ultrasound (IVUS) guidance has previously been shown to be a safe and effective technique, especially for critically ill patients, with initial experience of a prospectively implemented algorithm. The purpose of this study was to evaluate the effectiveness of IVUS-guided filter placement in critically ill patients with experience now extending out 5 years from implementation. All patients undergoing bedside IVUS-guided IVCF placement from 2008 to 2012 were identified. Records were reviewed on the basis of IVCF reporting standards. Outcomes data including technical success, complications, and mortality were analyzed at 30 days. During the 5-year period, 398 patients underwent attempted bedside IVCF placement by IVUS. Technical feasibility was possible in 396 cases (99.5%); two bedside procedures were aborted because of inadequate IVUS visualization. Overall technical success was achieved in 393 of 396 (99.2%), with malpositioned IVCF in three cases. An optional IVCF was used in 372 (93.9%) and a permanent IVCF in 24 (6.1%). Single-puncture technique was performed in 388 (97.4%); additional dual access was required in 10 (2.6%). Periprocedural complications were rare (3.0%) and included malpositioning that required retrieval and repositioning or an additional IVCF (3), filter tilt ≥20 degrees (4), arteriovenous fistulas (2), insertion site thrombosis (2), and hematoma (1). Comparison of the first 100 procedures performed within the sample population with the last 100 procedures revealed an overall success rate of 96% in the first 100 compared with 100% in the last 100 (P = .043). There were no deaths related to pulmonary embolism or IVCF-related problems. On the basis of 5 years of experience with bedside IVCF placement in critically ill patients, the IVUS-guided IVCF technique continues to be a safe and effective option in this high-risk population, with a time-dependent improvement in outcome measures.

Although contrast venography is the standard imaging method for inferior vena cava (IVC) filter insertion, intravascular ultrasound (IVUS) imaging is a safe and effective option that allows for bedside filter placement and is especially advantageous for immobilized critically ill patients by limiting resource use, risk of transportation, and cost. This study reviewed the effectiveness of a prospectively implemented algorithm for IVUS-guided IVC filter placement in this high-risk population. Current evidence-based guidelines were used to create a clinical decision algorithm for IVUS-guided IVC filter placement in critically ill patients. After a defined lead-in phase to allow dissemination of techniques, the algorithm was prospectively implemented on January 1, 2008. Data were collected for 1 year using accepted reporting standards and a quality assurance review performed based on intent-to-treat at 6, 12, and 18 months. As defined in the prospectively implemented algorithm, 109 patients met criteria for IVUS-directed bedside IVC filter placement. Technical feasibility was 98.1%. Only 2 patients had inadequate IVUS visualization for bedside filter placement and required subsequent placement in the endovascular suite. Technical success, defined as proper deployment in an infrarenal position, was achieved in 104 of the remaining 107 patients (97.2%). The filter was permanent in 21 (19.6%) and retrievable in 86 (80.3%). The single-puncture technique was used in 101 (94.4%), with additional dual access required in 6 (5.6%). Periprocedural complications were rare but included malpositioning requiring retrieval and repositioning in three patients, filter tilt >/=15 degrees in two, and arteriovenous fistula in one. The 30-day mortality rate for the bedside group was 5.5%, with no filter-related deaths. Successful placement of IVC filters using IVUS-guided imaging at the bedside in critically ill patients can be established through an evidence-based prospectively implemented algorithm, thereby limiting the need for transport in this high-risk population.

Various special techniques for blind bedside transpyloric tube placement have been introduced into clinical practice. However, transpyloric spiral tube placement facilitated by a blind bedside method has not yet been reported. The objective of this prospective study was to evaluate the safety and efficiency of blind bedside postpyloric placement of a spiral tube as a rescue therapy subsequent to failed spontaneous transpyloric migration in critically ill patients. This prospective, tricentric, observational study was conducted in the intensive care units (ICUs) of three tertiary hospitals. A total of 127 consecutive patients with failed spontaneous transpyloric spiral tube migration despite using prokinetic agents and still required enteral nutrition for more than 3 days were included. The spiral tube was inserted postpylorically using the blind bedside technique. All patients received metoclopramide intravenously prior to tube insertion. The exact tube tip position was determined by radiography. The primary efficacy endpoint was the success rate of postpyloric spiral tube placement. Secondary efficacy endpoints were success rate of a spiral tube placed in the third portion of the duodenum (D3) or beyond, success rate of placement in the proximal jejunum, time to insertion, length of insertion, and number of attempts. Safety endpoints were metoclopramide-related and major adverse tube-associated events. In 81.9% of patients, the spiral feeding tubes were placed postpylorically; of these, 55.1% were placed in D3 or beyond and 33.9% were placed in the proximal jejunum, with a median time to insertion of 14 min and an average number of attempts of 1.4. The mean length of insertion was 95.6 cm. The adverse event incidence was 26.0%, and no serious adverse event was observed. Blind bedside postpyloric placement of a spiral tube, as a rescue therapy subsequent to failed spontaneous transpyloric migration in critically ill patients, is safe and effective. This technique may facilitate the early initiation of postpyloric feeding in the ICU. Chinese Clinical Trial Registry, ChiCTR-OPN-16008206 . Registered on 1 April 2016.

Instruments used to assess evidence-based practice (EBP) competence in nurses have been subjective, unreliable, or invalid. The Fresno test was identified as the only instrument to measure all the steps of EBP with supportive reliability and validity data. However, the items and psychometric properties of the original Fresno test are only relevant to measure EBP with medical residents. Therefore, the purpose of this paper is to describe the development of the adapted Fresno test for pediatric nurses, and provide preliminary validity and reliability data for its use with Bachelor of Science in Nursing-prepared pediatric bedside nurses. General adaptations were made to the original instrument's case studies, item content, wording, and format to meet the needs of a pediatric nursing sample. The scoring rubric was also modified to complement changes made to the instrument. Content and face validity, and intrarater reliability of the adapted Fresno test were assessed during a mixed-methods pilot study conducted from October to December 2013 with 29 Bachelor of Science in Nursing-prepared pediatric nurses. Validity data provided evidence for good content and face validity. Intrarater reliability estimates were high. The adapted Fresno test presented here appears to be a valid and reliable assessment of EBP competence in Bachelor of Science in Nursing-prepared pediatric nurses. However, further testing of this instrument is warranted using a larger sample of pediatric nurses in diverse settings. This instrument can be a starting point for evaluating the impact of EBP competence on patient outcomes. © 2018 Sigma Theta Tau International.

Usefulness of bedside tissue Doppler echocardiography and B-type natriuretic peptide (BNP) in differentiating congestive heart failure from noncardiac cause of acute dyspnea in elderly patients with a normal left ventricular ejection fraction and permanent, nonvalvular atrial fibrillation: insights from a prospective, monocenter study.

The incremental role of bedside tissue Doppler echocardiography and B-type natriuretic peptide (BNP) over the clinical judgment has been recently reported in the emergency diagnosis of congestive heart failure with a normal left ventricular ejection fraction (HFNEF). However, how well does this diagnostic strategy be applicable in the setting of atrial fibrillation is unknown. To investigate the usefulness of bedside tissue Doppler echocardiography and BNP in the emergency diagnosis of HFNEF in elderly patients with permanent, nonvalvular atrial fibrillation. Forty-one consecutive elderly patients with an ejection fraction > or =50% (mean age 84 years; 22 with HFNEF and 19 with noncardiac cause), hospitalized for acute dyspnea at rest, were prospectively enrolled; bedside septal E/Ea and BNP were obtained at admission. By multivariable logistic regression analysis including the clinical judgment of heart failure, E/Ea and BNP, E/Ea (P = 0.014) and BNP (P = 0.018) provided independent diagnostic information. Optimal cutoffs were 13 for E/Ea (area under the ROC curve of 0.846, P < 0.0001; sensitivity 81.8%, specificity 89.5%) and 253 pg/ml for BNP (area under the ROC curve of 0.928, P < 0.0001; sensitivity 86.4%, specificity 89.5%). The concordance between the clinical judgment and BNP concentration at the cutoff of 253 pg/ml correctly classified 24 of 25 patients; E/Ea at the cutoff of 13 correctly classified 14 of the 16 patients with discrepancy. Bedside tissue Doppler echocardiography and BNP provide useful additional diagnostic information over the clinical judgment for the emergency diagnosis of HFNEF in elderly patients with permanent, nonvalvular atrial fibrillation.

There is growing political pressure for nursing homes to implement the electronic medical record (EMR) but there is little evidence of its impact on resident care. The purpose of this study was to test the unique and combined contributions of EMR at the bedside and on-site clinical consultation by gerontological expert nurses on cost, staffing, and quality of care in nursing homes. Eighteen nursing facilities in 3 states participated in a 4-group 24-month comparison: Group 1 implemented bedside EMR, used nurse consultation; Group 2 implemented bedside EMR only; Group 3 used nurse consultation only; Group 4 neither. Intervention sites (Groups 1 and 2) received substantial, partial financial support from CMS to implement EMR. Costs and staffing were measured from Medicaid cost reports, and staff retention from primary data collection; resident outcomes were measured by MDS-based quality indicators and quality measures. Total costs increased in both intervention groups that implemented technology; staffing and staff retention remained constant. Improvement trends were detected in resident outcomes of ADLs, range of motion, and high-risk pressure sores for both intervention groups but not in comparison groups. Implementation of bedside EMR is not cost neutral. There were increased total costs for all intervention facilities. These costs were not a result of increased direct care staffing or increased staff turnover. Nursing home leaders and policy makers need to be aware of on-going hardware and software costs as well as costs of continual technical support for the EMR and constant staff orientation to use the system. EMR can contribute to the quality of nursing home care and can be enhanced by on-site consultation by nurses with graduate education in nursing and expertise in gerontology.

In 2008, self-poisoning with the herbicide propanil had a case-fatality of around 11% in Sri Lanka. A simple quantitative methaemoglobinemia bedside test was developed so that treatment could be titrated according to the methaemoglobin level. To determine whether the new method influenced patient management and changed the case fatality of propanil self-poisoning. The bedside test (using an inexpensive validated colour chart) was introduced in three hospitals (Anuradhapura, Polonnaruwa and Galle) in Sri Lanka from 2008. Junior ward staff were given a brief training on how to use the chart for quantitative estimation of methaemoglobin in patients with propanil poisoning and utilize the results in the context of the national treatment guidelines for propanil poisoning. It was taught that the bedside test should be done repeatedly from admission until it showed consistently low values of methaemoglobin. Treatment with the antidote methylene blue was suggested for patients whose methaemoglobin was greater than 20%. Limited clinical data on poisoning have been prospectively collected from these hospitals from 2003. The case-fatality and management before and after the change were compared with data up to December 2014. The case-fatality decreased from (38/401) 9.5% to (8/262) 3.1% [difference: -6.4%, 95% CI: -10 to -3]. Methylene blue use increased from under 10% of patients before to 55% of patients after the intervention. More patients received repeat doses and infusions, and few received ascorbic acid and exchange transfusion. The simple bedside test for methaemoglobinemia was readily adopted into routine practice and led to large changes in management. A substantial reduction in mortality from propanil poisoning occurred after this intervention.

Bedside ROP screening and telemedicine interpretation integrated to a neonatal transport system: Economic aspects and return on investment analysis.

Peter Cerny Ambulance Service - Premature Eye Rescue Program (PCA-PERP) uses digital retinal imaging (DRI) with remote interpretation in bedside ROP screening, which has advantages over binocular indirect ophthalmoscopy (BIO) in screening of premature newborns. We aimed to demonstrate that PCA-PERP provides good value for the money and to model the cost ramifications of a similar newly launched system. As DRI was demonstrated to have high diagnostic performance, only the costs of bedside DRI-based screening were compared to those of traditional transport and BIO-based screening (cost-minimization analysis). The total costs of investment and maintenance were analyzed with micro-costing method. A ten-year analysis time-horizon and service provider's perspective were applied. From the launch of PCA-PERP up to the end of 2014, 3722 bedside examinations were performed in the PCA covered central region of Hungary. From 2009 to 2014, PCA-PERP saved 92,248km and 3633 staff working hours, with an annual nominal cost-savings ranging from 17,435 to 35,140 Euro. The net present value was 127,847 Euro at the end of 2014, with a payback period of 4.1years and an internal rate of return of 20.8%. Our model presented the NPVs of different scenarios with different initial investments, annual number of transports and average transport distances. PCA-PERP as bedside screening with remote interpretation, when compared to a transport-based screening with BIO, produced better cost-savings from the perspective of the service provider and provided a return on initial investment within five years after the project initiation.

Introduction Nursing bedside handover in hospital has been identified as an opportunity to involve patients and promote patient-centred care. It is important to consider the preferences of both patients and nurses when implementing bedside handover to maximise the successful uptake of this policy. We outline a study which aims to (1) identify, compare and contrast the preferences for various aspects of handover common to nurses and patients while accounting for other factors, such as the time constraints of nurses that may influence these preferences.; (2) identify opportunities for nurses to better involve patients in bedside handover and (3) identify patient and nurse preferences that may challenge the full implementation of bedside handover in the acute medical setting. Methods and analysis We outline the protocol for a discrete choice experiment (DCE) which uses a survey design common to both patients and nurses. We describe the qualitative and pilot work undertaken to design the DCE. We use a D-efficient design which is informed by prior coefficients collected during the pilot phase. We also discuss the face-to-face administration of this survey in a population of acutely unwell, hospitalised patients and describe how data collection challenges have been informed by our pilot phase. Mixed multinomial logit regression analysis will be used to estimate the final results. Ethics and dissemination This study has been approved by a university ethics committee as well as two participating hospital ethics committees. Results will be used within a knowledge translation framework to inform any strategies that can be used by nursing staff to improve the uptake of bedside handover. Results will also be disseminated via peer-reviewed journal articles and will be presented at national and international conferences. PMID:26560060

Hand hygiene is a major means for preventing healthcare-associated infections. One critical point in understanding poor compliance is the lack of relevant markers used to monitor practices systematically. This study analysed hand hygiene compliance and associated factors with a radio-frequency-identification-based real-time continuous automated monitoring system in an infectious disease ward with 17 single bedrooms. Healthcare workers (HCWs) were tracked while performing routine care over 171 days. A multi-level multi-variate logistics model was used for data analysis. The main outcome measures were hand disinfection before entering the bedroom (outside use) and before entering the patient care zone, defined as the zone surrounding the patient's bed (inside/bedside use). Variables analysed included HCWs' characteristics and behaviour, patients, room layouts, path chains and duration of HCWs' paths. In total, 4629 paths with initial hand hygiene opportunities when entering the patient care zone were selected, of which 763 (16.5%), 285 (6.1%) and 3581 (77.4%) were associated with outside use, inside/bedside use and no use, respectively. Hand hygiene is caregiver-dependent. The shorter the duration of the HCW's path, the worse the bedside hand hygiene. Bedside hand hygiene is improved when one or two extra HCWs are present in the room. Hand hygiene compliance at the bedside, as analysed using the continuous monitoring system, depended upon the HCW's occupation and personal behaviour, number of HCWs, time spent in the room and (potentially) dispenser location. Meal tray distribution was a possible factor in the case of failure to disinfect hands. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

Mixed methods evaluation of a quality improvement and audit tool for nurse-to-nurse bedside clinical handover in ward settings.

Nurse bedside handover quality is influenced by complex interactions related to the content, processes used and the work environment. Audit tools are seldom tested in 'real' settings. Examine the reliability, validity and usability of a quality improvement tool for audit of nurse bedside handover. Naturalistic, descriptive, mixed-methods. Six inpatient wards at a single large not-for-profit private health service in Victoria, Australia. Five nurse experts and 104 nurses involved in 199 change-of-shift bedside handovers. A focus group with experts and pilot test were used to examine content and face validity, and usability of the handover audit tool. The tool was examined for inter-rater reliability and usability using observation audits of handovers across six wards. Data were collected in 2013-2014. Two independent observers for 72 audits demonstrated acceptable inter-observer agreement for 27 (77%) items. Reliability was weak for items examining the handover environment. Seventeen items were not observed reflecting gaps in practices. Across 199 observation audits, gaps in nurse bedside handover practice most often related to process and environment, rather than content items. Usability was impacted by high observer burden, familiarity and non-specific illustrative behaviours. The reliability and validity of most items to audit handover content was acceptable. Gaps in practices for process and environment items were identified. Context specific exemplars and reducing the items used at each handover audit can enhance usability. Further research is needed to develop context specific exemplars and undertake additional reliability testing using a wide range of handover settings. CONTRIBUTION OF THE PAPER.

Platelets have a pivotal role in the initial defense against insult to the vasculature and are also recognized of critical importance in the acute care settings of percutaneous coronary intervention and cardiopulmonary bypass. In these environments both platelet count and function may be markedly compromised. Unfortunately, current assays to evaluate the parameters of platelet count and function are of limited utility for bed-side testing. Moreover, it is suggested that there may be significant inter patient variation in response to antiplatelet therapy that may be exacerbated by other agents (e.g. heparin) that are routinely administered during cardiac intervention. Here we describe a practical, rapid and user-friendly whole blood platelet function assay that has been developed for use in bed-side settings. Platelet agonists were formulated with an anticoagulant and lyophilized in blood collection tubes standardised to receive a l mL fresh whole blood sample. In the presence of an agonist, platelets are activated and interact (aggregate). Using traditional cell counting principles, non-aggregated platelets are counted whereas aggregated platelets are not. The percentage (%) of functional platelets in reference to a baseline tube may then be determined. Results are available within four minutes. Platelet aggregation in whole blood demonstrated good correlation with turbidometric aggregometry for both ADP (r=0.91) and collagen (r=0.88). Moreover, in clinical settings where antiplatelet agents were administered, this rapid, bed-side, platelet function assay demonstrated utility in monitoring patient response to these therapies. This novel bed-side assay of platelet function is extremely suitable for the clinical environment with a rapid turn-around time. In addition, it provides a full haematology profile, including platelet count, and should permit enhancement of transfusion and interventional decisions.

Dying is a natural process, yet physicians are often uncomfortable caring for dying patients. Learners have limited exposure to curriculum on caring for dying patients and often navigate these encounters without appropriate skills and confidence. We developed and implemented the Double Parallel Curriculum in Palliative Care (DP-PC): End-of-Life (EOL) module. The DP-PC focuses on teaching third-year medical students (MS3) to not only take care of patients in their last hours of life but give learners the confidence to teach patient's families what to expect as they hold vigil at their loved one's bedside. To develop and implement an educational intervention that improves learners' knowledge and confidence in EOL patient and family care. To expand learner confidence to a dual level (learners become teachers) with a simplified and culturally sensitive electronic bedside teaching tool designed to guide learners and patients/families conversations. Curriculum was completed during MS3 ambulatory rotation and included pre-/posttests, an online case-based module, faculty demonstration, and learner role-play using the bedside teaching tool. A total of 247 participants took the pretest, 222 participants took the posttest, and 222 participants matched the pre-/posttest surveys. Students' knowledge of EOL care and the confidence to teach other learners and families about EOL care significantly improved after completing the curriculum. The DP-PC is a technology-savvy educational intervention that improves learner confidence and knowledge toward caring for dying patients and their families. Easy access, technology-based teaching tools may enhance bedside teaching of health-care learners and improve the care of patients and their families at the end of life.

This is the sixth in a series of articles from Massachusetts General Hospital in Boston describing one general medical unit's experiences with Transforming Care at the Bedside (TCAB). An initiative begun by the Robert Wood Johnson Foundation (RWJF) and the Institute for Healthcare Improvement, TCAB was developed as a way to improve care on medical-surgical units, patients' and family members' experience of care, and teamwork among care team members and to increase nurse satisfaction and retention. The TCAB philosophy engages all care leaders, but empowers bedside nurses to generate ideas and solutions for change. Mass General is one of 68 hospitals participating in a two-year TCAB initiative led by the American Organization of Nurse Executives and funded with a grant from the RWJF.

Oropharyngeal dysphagia is a highly prevalent comorbidity in neurological patients and presents a serious health threat, which may le to outcomes of aspiration pneumonia ranging from hospitalization to death. Therefore, an early identification of risk followed by an accurate diagnosis of oropharyngeal dysphagia is fundamental. This systematic review provides an update of currently available bedside screenings to identify oropharyngeal dysphagia in neurological patients. An electronic search was carried out in the databases PubMed, Embase, CINAHL, and PsychInfo (formerly PsychLit), and all hits from 2008 up to December 2012 were included in the review. Only studies with sufficient methodological quality were considered, after which the psychometric characteristics of the screening tools were determined. Two relevant bedside screenings were identified, with a minimum sensitivity and specificity of ≥70 and ≥60 %, respectively.

In clinical practice, the history and physical examination are being superseded by laboratory tests and biomedical technology. The author discusses the importance of the clinical examination as the basis for clinical reasoning and of direct observation of students at the patients' bedside in order to assess their diagnostic reasoning. Greater attention to the clinical examination would lead not only to improved clinical skills but also to more cost-effective use of ancillary investigations and, moreover, to a better understanding of the patient by the physician.

The aim of this project was to describe hospital nurses' work activity through observations, nurses' perceptions of time spent on tasks, and electronic health record time stamps. Nurses' attitudes toward technology and patients' perceptions and satisfaction with nurses' time at the bedside were also examined. Activities most frequently observed included documenting in and reviewing the electronic health record. Nurses' perceptions of time differed significantly from observations, and most patients rated their satisfaction with nursing time as excellent or good.

The purpose of this study was to design a repeatable universal rehabilitation program in which patients with hemiplegia can participate voluntarily, complementing physical and occupational therapies to increase voluntary exercise practice rate. Also, this study attempted to identify the relationship between psychological resilience due to the implementation of self-bedside exercise and functional recovery of activity of daily living (ADL). 12 patients with hemiplegia voluntarily participated in 8 weeks of self-bedside exercise 5 times a day and more than 5 days a week. Their program implementation, resilience, activities of daily living (MBI), upper limb motor functions (MFT), and balance ability (BBS) were analyzed and compared before and after the program. Compared to before implementing the program, significant increases were found in resilience, MBI, BBS, and MFT in the affected side after the implementation, and the resilience scores showed statistically positive correlation in MBI and MFT. Also, the change in resilience before and after the program implementation showed a statistically positive correlation. Therefore, it can be concluded that the self-bedside exercise developed in this study had a positive effect on voluntary participation in exercise as well as resilience and ADL. However, many studies which complement the psychological aspects of hemiparetic patients with stroke are still needed. PMID:25830141

Mechanical ventilation is one of the most important therapeutic interventions in neonatal and pediatric ICUs. Telemedicine has been shown to reliably extend pediatric intensivist expertise to facilities where expertise is limited. If reliable, telemedicine may extend the reach of pediatric respiratory therapists (RTs) to facilities where expertise does not exist or free up existing RT resources for important face-to-face activities in facilities where expertise is limited. The aim of this study was to determine how well respiratory assessments for ventilated neonates and children correlated when performed simultaneously by 2 RTs face-to-face and via telemedicine. We conducted a pilot study including 40 assessments by 16 RTs on 11 subjects (5 neonatal ICU; 6 pediatric ICU). Anonymously completed intake forms by 2 different RTs concurrently assessing 14 ventilator-derived and patient-based respiratory variables were used to determine correlations. Forty paired assessments were performed. Median telemedicine assessment time was 8 min. The Pearson correlation coefficient (r) was used to determine agreement between continuous data, and the Cohen kappa statistics were used for binary variables. Pressure control, PEEP, breathing frequency, and FIO2 perfectly correlated (r = 1, all P < .001) as did the presence of a CO2 monitor and need for increased ventilatory support (kappa = 1). The Pearson correlation coefficient for VT, minute ventilation, mean airway pressure, and oxygen saturation ranged from 0.84 to 0.97 (all P < .001). kappa = 0.41 (95% CI 0.02-0.80) for patient-triggered breaths, and kappa = 0.57 (95% CI 0.19-0.94) for breathing frequency higher than set frequency. kappa = -0.25 (95% CI -0.46 to -0.04) for need for suctioning. Telemedicine technology was acceptable to RTs. Telemedicine evaluations highly correlated with face-to-face for 10 of 14 aspects of standard bedside respiratory assessment. Poor correlation was noted for more complex, patient-generated parameters, highlighting the importance of further investigation incorporating a virtual stethoscope.

Nursing shift report on the medical-surgical units of a large teaching hospital was modified from a recorded report to a blend of both recorded and bedside components. Comparisons between baseline and postimplementation data indicated increased patient satisfaction and nurse perception of accountability and patient involvement but reduced nurse perceptions of efficiency and effectiveness of report. Patient falls at shift change and medication errors were reduced, whereas nurse overtime remained unchanged.

To compare diagnostic accuracy of intensivists to radiologists in reading bedside chest X-rays. In a retrospective trial, 33 bedside chest X-rays were evaluated by five radiologists and five intensivists with different experience. Images were evaluated for devices and lung pathologies. Interobserver agreement and diagnostic accuracy were calculated. Computed tomography served as reference standard. Seniors had higher diagnostic accuracy than residents (mean-ExpB(Senior)=1.456; mean-ExpB(Resident)=1.635). Interobserver agreement for installations was more homogenously distributed between radiologists compared to intensivists (ExpB(Rad)=1.204-1.672; ExpB(Int)=1.005-2.368). Seniors had comparable diagnostic accuracy. No significant difference in diagnostic performance was seen between seniors of both disciplines, whereas the resident intensivists might still benefit from an interdisciplinary dialogue.

Ham, Melissa R; Okada, Pamela; White, Perrin C

2004-03-01

Diabetic ketoacidosis (DKA) is a serious complication of diabetes mellitus marked by characteristic biochemical derangements. Diagnosis and management involve frequent evaluation of these biochemical parameters. Reliable bedside equivalents for these laboratory studies may help reduce the time to treatment and reduce costs. We evaluated the precision and bias of a bedside serum ketone meter in the acute care setting. Serum ketone results using the Precision Xtra glucometer/ketone meter (Abbott Laboratories, MediSense Products Inc., Bedford, MA, USA) correlated strongly with the Children's Medical Center of Dallas' laboratory values within the meter's value range. Meter ketone values steadily decreased during the treatment of DKA as pH and CO(2) levels increased and acidosis resolved. Therefore, the meter may be useful in monitoring therapy for DKA. This meter may also prove useful in identifying patients at risk for DKA in physicians' offices or at home.

Art at the Bedside: Reflections on Use of Visual Imagery in Hospital Chaplaincy.

2016-03-01

'Art at the Bedside' is the name given to a hospital visitation program during which works of art loaded onto a computer are used to start conversations with patients and their families. The article traces the genesis of the program that evolved from the author's dual training in art museum education and hospital chaplaincy through the evolution of the practice, now in its sixth year. Reflections on the practice itself are the focus of this article, from identifying the kinds of responses frequently elicited by the artwork to understanding how these works of art seem to forge immediate connections between the patient and the facilitator. Ultimately posed in this reflection is whether the 'Art at the Bedside' experience might suggest a future for the integration of the visual arts more broadly into hospital - and related - chaplaincy. © The Author(s) 2016.

Between the bench, the bedside and the office: The need to build bridges between working neuroscientists and ethicists.

PubMed

Brosnan, Caragh; Cribb, Alan

2014-12-01

This paper presents findings from an empirical study that explored the meaning of ethics in the everyday work of neuroscientists. Observation and interviews were carried out in one neuroscience research group that was involved in bench-to-bedside translational research. We focus here specifically on the scientists' perceptions of bioethics. Interviewees were often unfamiliar with bioethics as a discipline, particularly the more junior members of the group. Those who were aware of its existence largely viewed it as something distant from them, and as either too abstract, not relevant or an alien imposition on their work. Some interviewees themselves pointed to the need for better 'bridge building' between ethical principles and real-world examples drawn from scientific practice, and we argue that this space is where a more empirically grounded ethics may be useful in terms of actually engaging scientists at both the bench and the bedside.

The development and initial validation of a sensitive bedside cognitive screening test.

PubMed

Faust, D; Fogel, B S

1989-01-01

Brief bedside cognitive examinations such as the Mini-Mental State Examination are designed to detect delirium and dementia but not more subtle or delineated cognitive deficits. Formal neuropsychological evaluation provides greater sensitivity and detects a wider range of cognitive deficits but is too lengthy for efficient use at the bedside or in epidemiological studies. The authors developed the High Sensitivity Cognitive Screen (HSCS), a 20-minute interview-based test, to identify patients who show disorder on formal neuropsychological evaluation. An initial study demonstrated satisfactory test-retest and interrater reliability. The HSCS was then administered to 60 psychiatric and neurological patients with suspected cognitive deficits but without gross impairment, who also completed formal neuropsychological testing. Results of both tests were independently classified as either normal, borderline, or abnormal. The HSCS correctly classified 93% of patients across the normal-abnormal dichotomy and showed promise for characterizing the extent and severity of cognitive dysfunction.

Chalk talks - where the teacher is equipped solely with a writing utensil and a writing surface - have been used for centuries, yet little has been written about strategies for their use in medical education. Structured education proximal to patient encounters (during rounds, at the bedside, or in between patients in clinic) maximizes the opportunities for clinical learning. This paper presents a strategy to bring mini-chalk talks (MCTs) to the bedside as a practical way to provide relevant clinical teaching by visually framing teachable moments. Grounded in adult learning theory, MCTs leverage teaching scripts to facilitate discussion, involve learners at multiple levels, and embrace the increased retention associated with visual aids. These authors provide specific recommendations for the design and implementation of MCT sessions including what topics work well, how to prepare, and how to involve and engage the learners.

Background Placement accuracy of ventriculostomy catheters is reported in a wide and variable range. Development of an efficient image-guidance system may improve physician performance and patient safety. Objective We evaluate the prototype of Smart Stylet, a new electromagnetic image-guidance system for use during bedside ventriculostomy. Methods Accuracy of the Smart Stylet system was assessed. System operators were evaluated for their ability to successfully target the ipsilateral frontal horn in a phantom model. Results Target registration error across 15 intracranial targets ranged from 1.3 – 4.6 mm (mean 3.1 mm). Using Smart Stylet guidance, a test operator successfully passed a ventriculostomy catheter to a shifted ipsilateral frontal horn 20/20 (100%) times from the frontal approach in a skull phantom. Without Smart Stylet guidance, the operator was successful 4/10 (40 %) from the right frontal approach and 6/10 (60 %) from the left frontal approach. In a separate experiment, resident operators were successful 2/4 (50%) when targeting the shifted ipsilateral frontal horn with Smart Stylet guidance and 0/4 (0 %) without image-guidance using a skull phantom. Conclusions Smart Stylet may improve the ability to successfully target the ventricles during frontal ventriculostomy. PMID:25662506

1987-08-01

To control post-operative bleeding from the resected cavity in transurethral resection of the prostate (TUR-P), 20,000 units of thrombin dissolved in 5-20 ml of physiological saline was injected into the cavity in one shot with a new type of 3-way Foley catheter. The catheter has two holes close to the balloon, and the holes provide outlets through which the solution is directly injected into the cavity. Out of 23 patients between 58 and 87 years old, 11 were given thrombin and 12 were control cases. In each case, urine blood volume (ml/hr) was determined before (a) and after (b) injection. The hemostatic effect was assessed with a "hemostatic index" of b/a. There was a statistically significant difference in the hemostatic indices between thrombin group and the control. (p less than 0.02) This new hemostatic method proved to be a very useful easy bed-side technique to control bleeding even in sudden bleeding after TUR-P. No serious side effects were found during the course of this study.

This secondary analysis from a larger mixed methods study with a sequential explanatory design investigates the clinical challenges for nurses providing patient care, in an airborne and contact isolation room, while using a computer on wheels for medication administration in a simulated setting. Registered nurses, who regularly work in clinical care at the patient bedside, were recruited as study participants in the simulation and debriefing experience. A live volunteer acted as the standardized patient who needed assessment and intravenous pain medication. The simulation was video recorded in a typical hospital room to observe participating nurses conducting patient care in an airborne and contact isolation situation. Participants then reviewed their performance with study personnel in a formal, audio-recorded debriefing. Isolation behaviors were scored by an expert panel, and the debriefing sessions were analyzed. Considerable variation was found in behaviors related to using a computer on wheels while caring for a patient in isolation. Currently, no nursing care guidelines exist on the use of computers on wheels in an airborne and contact isolation room. Specific education is needed on nursing care processes for the proper disinfection of computers on wheels and the reduction of the potential for disease transmission from environmental contamination.

Objective: To create and validate a simple, standardized version of the antisaccade (AS) task that requires no specialized equipment for use as a measure of executive function in multicenter clinical studies. Methods: The bedside AS (BAS) task consisted of 40 pseudorandomized AS trials presented on a laptop computer. BAS performance was compared with AS performance measured using an infrared eye tracker in normal elders (NE) and individuals with mild cognitive impairment (MCI) or dementia (n = 33). The neuropsychological domain specificity of the BAS was then determined in a cohort of NE, MCI, and dementia (n = 103) at UCSF, and the BAS was validated as a measure of executive function in a 6-center cohort (n = 397) of normal adults and patients with a variety of brain diseases. Results: Performance on the BAS and laboratory AS task was strongly correlated and BAS performance was most strongly associated with neuropsychological measures of executive function. Even after controlling for disease severity and processing speed, BAS performance was associated with multiple assessments of executive function, most strongly the informant-based Frontal Systems Behavior Scale. Conclusions: The BAS is a simple, valid measure of executive function in aging and neurologic disease. PMID:22573640

Objective Most studies have assessed conflict between clinicians and surrogate decision makers in ICUs from only clinicians’ perspectives. It is unknown if surrogates’ perceptions differ from clinicians’. We sought to determine the degree of agreement between physicians and surrogates about conflict, and to identify predictors of physician-surrogate conflict. Design Prospective cohort study. Setting Four ICUs of two hospitals in San Francisco, California. Patients 230 surrogate decision makers and 100 physicians of 175 critically ill patients. Measurements Questionnaires addressing participants’ perceptions of whether there was physician-surrogate conflict, as well as attitudes and preferences about clinician-surrogate communication; kappa scores to quantify physician-surrogate concordance about the presence of conflict; and hierarchical multivariate modeling to determine predictors of conflict. Main Results Either the physician or surrogate identified conflict in 63% of cases. Physicians were less likely to perceive conflict than surrogates (27.8% vs 42.3%; p=0.007). Agreement between physicians and surrogates about conflict was poor (kappa = 0.14). Multivariable analysis with surrogate-assessed conflict as the outcome revealed that higher levels of surrogates’ satisfaction with physicians’ bedside manner were associated with lower odds of conflict (OR: 0.75 per 1 point increase in satisfaction, 95% CI 0.59–0.96). Multivariable analysis with physician-assessed conflict as the outcome revealed that the surrogate having felt discriminated against in the healthcare setting was associated with higher odds of conflict (OR 17.5, 95% CI 1.6–190.1) while surrogates’ satisfaction with physicians’ bedside manner was associated with lower odds of conflict (0–10 scale, OR 0.76 per 1 point increase, 95% CI 0.58–0.99). Conclusions Conflict between physicians and surrogates is common in ICUs. There is little agreement between physicians and surrogates about whether physician-surrogate conflict has occurred. Further work is needed to develop reliable and valid methods to assess conflict. In the interim, future studies should assess conflict from the perspective of both clinicians and surrogates.

Staff nurses are pivotal in leading change related to quality improvement efforts, although many lack skills to steer change from the bedside. The American Association of Critical-Care Nurses (AACN) staff nurse leadership program, Clinical Scene Investigator (CSI) Academy, teaches and empowers staff nurses in leadership skills and change concepts to translate evidence into practice affecting patient outcomes. To describe the curriculum of the AACN CSI Academy that provides staff nurses with the leadership skills required to create unit-based change projects that positively impact patient/family outcomes. The curriculum of the Academy included leadership topics, communication, change concepts, quality improvement methods, project management, and data management and analysis. Each team of participants collected project data to show improvements in patient care. The program evaluation used many data sources to assess the program effectiveness, relating to the professional growth of the participant nurses. The participants assessed project patient outcomes, sustainability, and spread. The first cohort of CSI participants included 164 direct care nurses from 42 hospitals in 6 cities. They rated the Academy highly in the program evaluation, and they reported that the Academy contributed to their professional development. The individual hospital quality improvement projects resulted in positive patient and estimated fiscal outcomes that were generally sustained 1 year after the program. With the skills, tools, and support obtained from participation in the CSI Academy, staff nurses can make substantial contributions to their organizations in clinical and possibly fiscal outcomes. ©2017 American Association of Critical-Care Nurses.

SUMMARY Vertigo is generally due to a benign disorder, but it is the most common symptom associated with misdiagnosis of stroke. In this pilot study, we preliminarily assessed the diagnostic performance of a structured bedside algorithm to differentiate central from non-central acute vertigo (AV). Adult patients presenting to a single Emergency Department with vertigo were evaluated with STANDING (SponTAneous Nystagmus, Direction, head Impulse test, standiNG) by one of five trained emergency physicians or evaluated ordinarily by the rest of the medical staff (control group). The gold standard was a complete audiologic evaluation by a clinicians who are experts in assessing dizzy patients and neuroimaging. Reliability, sensibility and specificity of STANDING were calculated. Moreover, to evaluate the potential clinical impact of STANDING, neuroimaging and hospitalisation rates were compared with control group. A total of 292 patients were included, and 48 (16.4%) had a diagnosis of central AV. Ninety-eight (33.4%) patients were evaluated with STANDING. The test had good interobserver agreement (k = 0.76), with very high sensitivity (100%, 95%CI 72.3-100%) and specificity (94.3%, 95%CI 90.7-94.3%). Furthermore, hospitalisation and neuroimaging test rates were lower in the STANDING than in the control group (27.6% vs. 50.5% and 31.6% vs. 71.1%, respectively). In conclusion, STANDING seems to be a promising simple structured bedside algorithm that in this preliminary study identified central AV with a very high sensitivity, and was associated with significant reduction of neuroimaging and hospitalisation rates.

There is limited evidence that the use of severity of illness scores in pediatric patients can facilitate timely admission to the intensive care unit or improve patient outcomes. To determine the effect of the Bedside Paediatric Early Warning System (BedsidePEWS) on all-cause hospital mortality and late admission to the intensive care unit (ICU), cardiac arrest, and ICU resource use. A multicenter cluster randomized trial of 21 hospitals located in 7 countries (Belgium, Canada, England, Ireland, Italy, New Zealand, and the Netherlands) that provided inpatient pediatric care for infants (gestational age ≥37 weeks) to teenagers (aged ≤18 years). Participating hospitals had continuous physician staffing and subspecialized pediatric services. Patient enrollment began on February 28, 2011, and ended on June 21, 2015. Follow-up ended on July 19, 2015. The BedsidePEWS intervention (10 hospitals) was compared with usual care (no severity of illness score; 11 hospitals). The primary outcome was all-cause hospital mortality. The secondary outcome was a significant clinical deterioration event, which was defined as a composite outcome reflecting late ICU admission. Regression analyses accounted for hospital-level clustering and baseline rates. Among 144 539 patient discharges at 21 randomized hospitals, there were 559 443 patient-days and 144 539 patients (100%) completed the trial. All-cause hospital mortality was 1.93 per 1000 patient discharges at hospitals with BedsidePEWS and 1.56 per 1000 patient discharges at hospitals with usual care (adjusted between-group rate difference, 0.01 [95% CI, -0.80 to 0.81 per 1000 patient discharges]; adjusted odds ratio, 1.01 [95% CI, 0.61 to 1.69]; P = .96). Significant clinical deterioration events occurred during 0.50 per 1000 patient-days at hospitals with BedsidePEWS vs 0.84 per 1000 patient-days at hospitals with usual care (adjusted between-group rate difference, -0.34 [95% CI, -0.73 to 0.05 per 1000 patient-days]; adjusted rate ratio, 0.77 [95% CI, 0.61 to 0.97]; P = .03). Implementation of the Bedside Paediatric Early Warning System compared with usual care did not significantly decrease all-cause mortality among hospitalized pediatric patients. These findings do not support the use of this system to reduce mortality. clinicaltrials.gov Identifier: NCT01260831.

Although postgraduate trainees play a well-accepted role in medical education, little consideration has traditionally been given to senior undergraduate trainees as teachers. Recently, research has shown senior medical students (SMS) can play an effective teaching role for junior medical students (JMS) in non-clinical medical settings. The purpose of our study was to understand the perceptions of SMSs as teachers in a clinical environment for JMS. All students who participated in our peer-led bedside teaching programme from September 2010 to May 2012 were invited to complete a questionnaire following their teaching session. Fifty-six of 70 JMS (80%) and 15 of 15 SMS (100%) participated. Survey questions addressed learning, bedside experiences, teacher effectiveness and the overall usefulness of these sessions. The data collected were analysed for significance of the perceptions reported. We found students reported positive and statistically significant results in all domains examined. JMS reported that sessions were highly valuable learning, improved confidence and comfort at the bedside, had excellent teaching and were a valuable addition to their clinical skills training. SMS reported getting highly valuable learning through preparation and developing improved comfort in a teaching role. Little consideration has traditionally been given to senior undergraduate trainees as teachers Our findings demonstrate that peer-directed learning in undergraduate medical education can be effectively implemented in the clinical arena. © 2015 John Wiley & Sons Ltd.

The Indiana Organ Procurement Organization (IOPO) utilizes preoperative bedside liver biopsies in certain extended-criteria donors (ECDs), obtained by the on-site coordinator, to determine the utility of pursuing donation. This study reports the clinical and financial outcomes for this management strategy. All bedside liver biopsies obtained in ECDs over a five-yr period were reviewed. Study variables included the following: indication for biopsy, biopsy results, taking the case to the operating room, transplantation of the donor liver, and graft survival. All biopsies were processed at a single university center. There were 110 donors biopsied. Primary indications included the following: old age (29%), extensive/current alcohol abuse (26%), hepatitis C-positive serology (21%), obesity (25%), and severely elevated liver function enzymes (18%). Biopsy results demonstrated a potentially transplantable liver in 73 cases (66%), all of whom were taken to the OR (while 37 ruled out for donation based upon liver biopsy [34%]). Of all biopsied livers, 49 ultimately were transplanted (45%). Intra-operative decisions included the following: transplant 51/73 (70%), surgeon decision to exclude 20/73 (27%), nonuse due to finding of malignancy two (3%). Bedside liver biopsy may be a valuable tool to determine the utility in pursuing donation in ECDs, particularly with liver-only donors. © 2014 John Wiley & Sons A/S.

To evaluate the amount of time housestaff spent at the bedside on physical examination skills with third-year medical students and whether housestaff enhanced physical examination skills. All Albert Einstein College of Medicine students who completed the third-year medicine inpatient clerkship at one of five participating sites evaluated housestaff (interns and residents) with whom they spent at least ten days. The students quantified the amount of time housestaff spent with them at the bedside and used a modified five-point Likert scale to evaluate housestaff's enhancement of students' physical examination skills. Data were analyzed separately for interns, but pooled for residents (years two and three). Differences between groups were tested using Wilcoxon rank-sum and by Mantel-Haenszel chi-square tests. Totals of 191 responses for interns and 166 responses for residents were collected from October 1999 to October 2000. Fifteen (8%) of the intern group and 59 (36%) of the resident group spent no time at the bedside (p <.0001). Students were most satisfied with enhancement of pulmonary, cardiovascular, and gastrointestinal skills and least satisfied with enhancement of ENT, eye, and genitourinary skills (p <.0001). Interns spent more time with students than did residents. Almost one third of the residents spent no time on physical examination skills with students. Training programs should re-emphasize the importance of housestaff's teaching at the bedside and address areas of deficiency.

Unexplained coma after critical illness can be multifactorial. We evaluated the diagnostic ability of bedside Optic Nerve Sheath Diameter [ONSD] as a screening test for non-traumatic radiographic cerebral edema. In a prospective study, mixed medical-surgical intensive care units [ICU] patients with non-traumatic coma [GCS < 9] underwent bedside ultrasonographic ONSD measurements. Non-traumatic radiographic cerebral edema [NTRCE] was defined as > 5 mm midline shift, cisternal, sulcal effacement, or hydrocephalus on CT. NTRCE was identified in 31 of 102 patients [30.4 %]. The area under the ROC curve for detecting radiographic edema by ONSD was 0.785 [95 % CI 0.695-0.874, p <0.001]. ONSD diameter of 0.57 cm was found to be the best cutoff threshold with a sensitivity 84 % and specificity 71 %, AUC 0.785 [95 % CI 0.695-0.874, p <0.001]. Using ONSD as a bedside test increased the post-test odds ratio [OR] for NTRCE by 2.89 times [positive likelihood ratio], whereas post-test OR for NTRCE decreased markedly given a negative ONSD test [ONSD measurement less than 0.57 cm]; negative likelihood ratio 0.22. The use of ONSD as a bedside test in patients with non-traumatic coma has diagnostic value in identifying patients with non-traumatic radiographic cerebral edema.

Patient safety during emergency department procedural sedation (EDPS) can be difficult to study. Investigators sought to delineate and experimentally assess EDPS performance and safety practices of senior-level emergency medicine residents through in situ simulation. Study sessions used 2 pilot-tested EDPS scenarios with critical action checklists, institutional forms, embedded probes, and situational awareness questionnaires. An experimental informatics system was separately developed for bedside EDPS process guidance. Postgraduate year 3 and 4 subjects completed both scenarios in randomized order; only experimental subjects were provided with the experimental system during second scenarios. Twenty-four residents were recruited into a control group (n = 12; 6.2 ± 7.4 live EDPS experience) and experimental group (n = 12; 11.3 ± 8.2 live EDPS experience [P = 0.10]). Critical actions for EDPS medication selection, induction, and adverse event recognition with resuscitation were correctly performed by most subjects. Presedation evaluations, sedation rescue preparation, equipment checks, time-outs, and documentation were frequently missed. Time-outs and postsedation assessments increased during second scenarios in the experimental group. Emergency department procedural sedation safety probe detection did not change across scenarios in either group. Situational awareness scores were 51% ± 7% for control group and 58% ± 12% for experimental group. Subjects using the experimental system completed more time-outs and scored higher Simulation EDPS Safety Composite Scores, although without comprehensive improvements in EDPS practice or safety. Study simulations delineated EDPS and assessed safety behaviors in senior emergency medicine residents, who exhibited the requisite medical knowledge base and procedural skill set but lacked some nontechnical skills that pertain to emergency department microsystem functions and patient safety. The experimental system exhibited limited impact only on in-simulation time-out compliance.

BACKGROUND: Radial artery access is commonly performed for coronary angiography and invasive hemodynamic monitoring. Despite limitations in diagnostic accuracy, the modified Allen test (manual occlusion of radial and ulnar arteries followed by release of the latter and assessment of palmar blush) is used routinely to evaluate the collateral circulation to the hand and, therefore, to determine patient eligibility for radial artery access. We sought to evaluate whether a smartphone application may provide a superior alternative to the modified Allen test. METHODS: We compared the modified Allen test with a smartphone heart rate–monitoring application (photoplethysmography readings detected using a smartphone camera lens placed on the patient’s index finger) in patients undergoing a planned cardiac catheterization. Test order was randomly assigned in a 1:1 fashion. All patients then underwent conventional plethysmography of the index finger, followed by Doppler ultrasonography of the radial and ulnar arteries (the diagnostic standard). The primary outcome was diagnostic accuracy of the heart rate–monitoring application. RESULTS: Among 438 patients who were included in the study, we found that the heart rate–monitoring application had a superior diagnostic accuracy compared with the modified Allen test (91.8% v. 81.7%, p = 0.002), attributable to its greater specificity (93.0% v. 82.8%, p = 0.001). We also found that this application had greater diagnostic accuracy for assessment of radial or ulnar artery patency in the ipsilateral and contralateral wrist (94.0% v. 84.0%, p < 0.001). INTERPRETATION: A smartphone application used at the bedside was diagnostically superior to traditional physical examination for confirming ulnar patency before radial artery access. This study highlights the potential for smartphone-based diagnostics to aid in clinical decision-making at the patient’s bedside. Trial registration: Clinicaltrials.gov, no. NCT02519491.

Medical students on clinical rotations rarely receive formal bedside ultrasound (BUS) training. We designed, implemented, and evaluated a standardized BUS curriculum for medical students on their Emergency Medicine (EM) rotation. Teaching was aimed toward influencing four cognitive and psychomotor learning domains: BUS instrumentation knowledge, image interpretation, image acquisition, and procedural guidance. Participants viewed three instructional Web-based tutorials on BUS instrumentation, the Focused Assessment for Sonography in Trauma (FAST) examination and ultrasound-guided central venous catheter (CVC) placement. Subsequently, participants attended a 3-hour hands-on training session to discuss the same content area and practice with faculty coaches. A Web-based, multiple-choice questionnaire was administered before and after the session. During the final week of the rotation, students returned for skills assessments on FAST image acquisition and CVC placement. Forty-five medical students on an EM rotation were enrolled. Sonographic knowledge overall mean score improved significantly from 66.6% (SD ±11.2) to 85.7% (SD ±10.0), corresponding to a mean difference of 19.1% (95% CI 15.5-22.7; p < 0.001). There were high pass rates for FAST (89.0%, 40/45) and CVC (96.0%, 43/45) skills assessments. There was no significant difference between medical student posttest and EM resident test scores 85.7% (SD ±10.0) and 88.1% (SD ± 7.6) (p = 0.40), respectively. A formal BUS curriculum for medical students on EM rotation positively influenced performance in several key learning domains. As BUS competency is required for residency in EM and other specialties, medical schools could consider routinely incorporating BUS teaching into their clinical rotation curricula. © 2014 Wiley Periodicals, Inc.

Functional magnetic resonance imaging (fMRI) may be adopted as a complementary tool for bedside observation in the disorders of consciousness (DOC). However, the diagnostic value of this technique is still debated because of the lack of accuracy in determining levels of consciousness within a single patient. Recently, Giacino and colleagues (2014) hypothesized that a longitudinal fMRI evaluation may provide a more informative assessment in the detection of residual awareness. The aim of this study was to measure the correspondence between clinically defined level of awareness and neural responses within a single DOC patient. We used a follow-up fMRI design in combination with a passive speech-processing task. Patient's consciousness was measured through time by using the Coma Recovery Scale. The patient progressed from a vegetative state (VS) to a minimally conscious state (MCS). Patient's task-related neural responses mirrored the clinical change from a VS to an MCS. Specifically, while in an MCS, but not a VS, the patient showed a selective recruitment of the left angular gyrus when he listened to a native speech narrative, as compared to the reverse presentation of the same stimulus. Furthermore, the patient showed an increased response in the language-related brain network and a greater deactivation in the default mode network following his progression to an MCS. Our findings indicate that longitudinal assessment of brain responses to passive stimuli can contribute to the definition of the clinical status in individual patients with DOC and represents an adequate counterpart of the bedside assessment during the diagnostic decision-making process.

2015-09-01

This study assessed whether photographs of burns on patients with dark-skin types could be used for accurate diagnosing and if the accuracy was affected by physicians' clinical background or case characteristics. 21 South-African cases (Fitzpatrick grades 4-6) of varying complexity were photographed using a camera phone and uploaded on a web-survey. Respondents were asked to assess wound depth (3 categories) and size (in percentage). A sample of 24 burn surgeons and emergency physicians was recruited in South-Africa, USA and Sweden. Measurements of accuracy (using percentage agreement with bedside diagnosis), inter- (n=24), and intra-rater (n=6) reliability (using percentage agreement and kappa) were computed for all cases aggregated and by case characteristic. Overall diagnostic accuracy was 67.5% and 66.0% for burn size and depth, respectively. It was comparable between burn surgeons and emergency physicians and between countries of practice. However, the standard deviations were smaller, showing higher similarities in diagnoses for burn surgeons and South-African clinicians compared to emergency physicians and clinicians from other countries. Case characteristics (child/adult, simple/complex wound, partial/full thickness) affected the results for burn size but not for depth. Inter- and intra-rater reliability for burn depth was 55% and 77%. Size and depth of burns on patients with dark-skin types could be assessed at least as well using photographs as at bedside with 67.5% and 66.0% average accuracy rates. Case characteristics significantly affected the accuracy for burn size, but medical specialty and country of practice seldom did in a statistically significant manner.

One third of patients admitted to an intensive care unit (ICU) will develop delirium. However, delirium is under-recognized by bedside clinicians without the use of delirium screening tools, such as the Intensive Care Delirium Screening Checklist (ICDSC) or the Confusion Assessment Method for the ICU (CAM-ICU). The CAM-ICU was updated in 2014 to improve its use by clinicians throughout the world. It has never been validated compared to the new reference standard, the Diagnostic and Statistical Manual of Mental Disorders 5th version (DSM-5). We made a prospective psychometric study in a 16-bed medical-surgical ICU of a French academic hospital, to measure the diagnostic performance of the 2014 updated CAM-ICU compared to the DSM-5 as the reference standard. We included consecutive adult patients with a Richmond Agitation Sedation Scale (RASS) ≥ -3, without preexisting cognitive disorders, psychosis or cerebral injury. Delirium was independently assessed by neuropsychological experts using an operationalized approach to DSM-5, by investigators using the CAM-ICU and the ICDSC, by bedside clinicians and by ICU patients. The sensitivity, specificity, positive and negative predictive values were calculated considering neuropsychologist DSM-5 assessments as the reference standard (primary endpoint). CAM-ICU inter-observer agreement, as well as that between delirium diagnosis methods and the reference standard, was summarized using κ coefficients, which were subsequently compared using the Z-test. Delirium was diagnosed by experts in 38% of the 108 patients included for analysis. The CAM-ICU had a sensitivity of 83%, a specificity of 100%, a positive predictive value of 100% and a negative predictive value of 91%. Compared to the reference standard, the CAM-ICU had a significantly (p < 0.05) higher agreement (κ = 0.86 ± 0.05) than the physicians,' residents' and nurses' diagnoses (κ = 0.65 ± 0.09; 0.63 ± 0.09; 0.61 ± 0.09, respectively), as well as the patient's own impression of feeling delirious (κ = 0.02 ± 0.11). Differences between the ICDSC (κ = 0.69 ± 0.07) and CAM-ICU were not significant (p = 0.054). The CAM-ICU demonstrated a high reliability for inter-observer agreement (κ = 0.87 ± 0.06). The 2014 updated version of the CAM-ICU is valid according to DSM-5 criteria and reliable regarding inter-observer agreement in a research setting. Delirium remains under-recognized by bedside clinicians.

There is emerging recognition of the need for continuous long term electrographic monitoring of the encephalopathic neonate. While full-montage EEG with video remains the gold standard for monitoring, it is limited in application due to the complexity of lead application and specialized interpretation of results. Amplitude integrated EEG (aEEG) is derived from limited channels (usually C3-P3, C4-P4) and is filtered, rectified and time-compressed to serve as a bedside electrographic trend monitor. Its simple application and interpretation has resulted in increasing use in neonatal units across the world. Validation studies with full montage EEG have shown reliable results in interpretation of EEG background and electrographic seizures, especially when used with the simultaneously displayed raw EEG trace. Several aEEG monitors are commercially available and seizure algorithms are being developed for use on these monitors. These aEEG monitors, complement conventional EEG and offer a significant advance in the feasibility of long term electrographic monitoring of the encephalopathic neonate.

We examined blood pressure in the abdominal aorta of mini pig under plasma inhalation of atmospheric pressure plasma flow. The coaxial atmospheric pressure plasma source has a tungsten wire inside a glass capillary, that is surrounded by a grounded tubular electrode. Plasma was generated under the following conditions; applied voltage: 8 kVpp, frequency: 3 kHz, and helium (He) gas flow rate: 1 L/min. On the other hand, sphygmomanometry of a blood vessel proceeded using a device comprising a disposable force transducer, and a bedside monitor for simultaneous electrocardiography and signal pressure measurements. We directly measured Nitric oxide (NO) using a catheter-type NO sensor placed in the coronary sinus through an angiography catheter from the abdomen. Blood pressure decreased from 110/65 to 90/40 mm Hg in the animals in vivo under plasma inhalation. The NO concentration in the abdominal aorta like the blood pressure, reached a maximum value at about 40 s and then gradually decreased.

Proteomics is more than just a list-generating exercise where increases or decreases in protein expression are identified. Proteomic technologies will ultimately characterize information-flow through the protein circuitry that interconnects the extracellular microenvironment to the serum or plasma macroenvironment through intracellular signaling systems and their control of gene transcription. The nature of this information can be a cause or a consequence of disease processes and how patients respond to therapy. Analysis of human cancer as a model for how proteomics can have an impact at the bedside can take advantage of several promising new proteomic technologies. These technologies are being developed for early detection and risk assessment, therapeutic targeting and patient-tailored therapy.

Nursing bedside handover in hospital has been identified as an opportunity to involve patients and promote patient-centred care. It is important to consider the preferences of both patients and nurses when implementing bedside handover to maximise the successful uptake of this policy. We outline a study which aims to (1) identify, compare and contrast the preferences for various aspects of handover common to nurses and patients while accounting for other factors, such as the time constraints of nurses that may influence these preferences.; (2) identify opportunities for nurses to better involve patients in bedside handover and (3) identify patient and nurse preferences that may challenge the full implementation of bedside handover in the acute medical setting. We outline the protocol for a discrete choice experiment (DCE) which uses a survey design common to both patients and nurses. We describe the qualitative and pilot work undertaken to design the DCE. We use a D-efficient design which is informed by prior coefficients collected during the pilot phase. We also discuss the face-to-face administration of this survey in a population of acutely unwell, hospitalised patients and describe how data collection challenges have been informed by our pilot phase. Mixed multinomial logit regression analysis will be used to estimate the final results. This study has been approved by a university ethics committee as well as two participating hospital ethics committees. Results will be used within a knowledge translation framework to inform any strategies that can be used by nursing staff to improve the uptake of bedside handover. Results will also be disseminated via peer-reviewed journal articles and will be presented at national and international conferences. Published by the BMJ Publishing Group Limited.

Efforts to improve care of patients with ESRD and the policies that guide those activities depend on evidence-based best practices derived from clinical trials and carefully conducted observational studies. Our review describes this process in the context of the translational research model (bench to bedside to populations), with a particular emphasis on bedside care. We illustrate some of its accomplishments and describe the limitations of the data and evidence supporting policy and practice. Copyright © 2016 by the American Society of Nephrology.

A case is reported of a 38-year-old man presenting with early Ludwig's angina. It is difficult to differentiate superficial from deep infections of the face and neck by physical examination alone. The diagnosis of this condition with bedside soft tissue ultrasound of the face is described. Ludwig's angina is an uncommon infection of the deep tissues of the face and neck that usually evolves from more superficial infections such as dental abscesses.

Time well spent? Assessing nursing-supply chain activities.

The amount of time nurses spend providing direct patient care seems to be continually eroding. So it's little wonder a survey conducted last year of critical care, OR nurses and nurse executives found that half of the 1600 respondents feel they spend too much time on supply chain duties. Most also said their supply chain duties impact patient safe ty and their ability to provide bedside care. Experts interviewed for this report believe it's time for supply chain leaders and nurses to develop a closer working partnership. Included are their recommendations to improve performance.

Auscultation of the lung is an important part of the respiratory examination and is helpful in diagnosing various respiratory disorders. Auscultation assesses airflow through the trachea-bronchial tree. It is important to distinguish normal respiratory sounds from abnormal ones for example crackles, wheezes, and pleural rub in order to make correct diagnosis. It is necessary to understand the underlying pathophysiology of various lung sounds generation for better understanding of disease processes. Bedside teaching should be strengthened in order to avoid erosion in this age old procedure in the era of technological explosion. PMID:26229557

There are varying and overlapping leadership characteristics that exemplify excellence in nursing leadership. To assess aspects of leadership that helps create a healthy work environment that supports nurses' provision of quality care at the bedside, the authors used a national survey instrument to examine the characteristics of nurse managers identified as excellent nurse leaders by their staff. The authors discuss their findings and a proposed theoretical model to explain specific nursing leadership characteristics that support staff nurse job satisfaction and retention.

2016-01-01

Indocyanine green (ICG) kinetics (PDR/R15) used to quantitatively assess hepatic function in the perioperative period of major resective surgery and liver transplantation have been the object of an extensive, updated and critical review. New, non invasive bedside monitors (pulse dye densitometry technology) make this opportunity widely available in clinical practice. After having reviewed basic concepts of hepatic clearance, we analysed the most common indications ICG kinetic parameters have nowadays in clinical practice, focusing in particular on the diagnostic and prognostic role of PDR and R15 in the perioperative period of major liver surgery and liver transplantation. As recently pointed out, even if of extreme interest, ICG clearance parameters have still some limitations, to be considered when using these tests. PMID:26981173

Determination of Vascular Waterfall Phenomenon by Bedside Measurement of Mean Systemic Filling Pressure and Critical Closing Pressure in the Intensive Care Unit

Background Mean systemic filling pressure (Pmsf) can be determined at the bedside by measuring central venous pressure (Pcv) and cardiac output (CO) during inspiratory hold maneuvers. Critical closing pressure (Pcc) can be determined using the same method measuring arterial pressure (Pa) and CO. If Pcc > Pmsf there is then a vascular waterfall. In this study we assessed the existence of a waterfall and its implications for the calculation of vascular resistances by determining Pmsf and Pcc at the bedside. Methods In 10 mechanically ventilated postcardiac surgery patients inspiratory hold maneuvers were performed, transiently increasing Pcv and decreasing Pa and CO to four different steady-state levels. For each patient values of Pcv and CO were plotted in a venous return curve to determine Pmsf. Similarly, Pcc was determined with a ventricular output curve plotted for Pa and CO. Measurements were performed in each patient before and after volume expansion with 0.5 l colloid and vascular resistances were calculated. Results For every patient the relationship between the four measurements of Pcv and CO and of Pa and CO was linear. Baseline Pmsf was 18.7±4.0 (mean±SD) mmHg and differed significantly from Pcc 45.5±11.1 mmHg; (p<0.0001). The difference of Pcc and Pmsf was 26.8±10.7 mmHg, indicating the presence of a systemic vascular waterfall. Volume expansion increased Pmsf (26.3±3.2 mmHg), Pcc (51.5±9.0 mmHg) and CO (5.5±1.8 to 6.8±1.8 l·min−1). Arterial (upstream of Pcc) and venous (down-stream of Pmsf) vascular resistance were 8.27±4.45 and 2.75±1.23 mmHg·min·l−1; the sum of both (11.01 mmHg·min·l−1) was significantly different from total systemic vascular resistance (16.56±8.57 mmHg·min·l−1, p=0.005). Arterial resistance was related to total resistance. Conclusions Vascular pressure gradients in cardiac surgery patients suggest the presence of a vascular waterfall phenomenon, which is not affected by CO. Thus measures of total systemic vascular resistance may become irrelevant in assessing systemic vasomotor tone. PMID:22344243

We aimed to determine i) the feasibility of nurses taking bedside measurements of microcirculatory parameters in real time in intensive care patients; and ii) whether such measurements would be comparable to those obtained by the classical delayed semi quantitative analysis made by a physician. This prospective observational study was conducted in a university hospital and was approved by our local Institutional Review Board (IRB 00006477). After ICU admission and study inclusion, a set of measurements of macrocirculatory and microcirculatory parameters was taken by the nurse in charge of the patient every 4 h within the first 12 h after admission and before and after every hemodynamic therapeutic intervention. Seventy-four sublingual microvascular measurements were performed with incident dark field illumination (IDF) microscopy in 20 mechanically ventilated patients hospitalized in the ICU. There were no significant differences between the microvascular flow index (MFI) taken in real time by the nurses and the delayed evaluation by the physician. In fact, the nurses' real-time measurement of MFI demonstrated good agreement with the physician's delayed measurement. The mean difference between the two MFIs was -0.15, SD = 0.28. The nurses' real-time MFI assessment showed 97 % sensitivity (95 % CI: 84-99 %) and 95 % specificity (95 % CI: 84-99 %) at detecting a MFI <2.5 obtained by a physician upon delayed semiquantitative measurement. Concerning the density, 81 % of the paramedical qualitative density measurements corresponded with the automatized total vessel density (TVD) measurements. The nurses' real-time TVD assessment showed 77 % sensitivity (95 % CI: 46-95 %) and 100 % specificity (95 % CI: 89-100 %) at detecting a TVD <8 mm/mm(2). A real-time qualitative bedside evaluation of MFI by nurses showed good agreement with the conventional delayed analysis by physicians. The bedside evaluations of MFI and TVD were highly sensitive and specific for detecting impaired microvascular flow and low capillary density. These results suggest that this real-time technique could become part of ICU nurse routine surveillance and be implemented in algorithms for hemodynamic resuscitation in future clinical trials and regular practice. These results are an essential step to demonstrate whether these real-time measurements have a clinical impact in the management of ICU patients.

The aim in this study was to assess the effectiveness of a quaternary ammonium chloride (QAC) surfactant in reducing surface staphylococcal contamination in a routinely operating medical ward occupied by patients who had tested positive for methicillin-resistant Staphylococcus aureus (MRSA). The QAC being tested is an antibacterial film that is sprayed onto a surface and can remain active for up to 8 h. A field experimental study was designed with the QAC plus daily hypochlorite cleaning as the experimental group and hypochlorite cleaning alone as the control group. The method of swabbing on moistened surfaces was used for sampling. It was found that 83% and 77% of the bedside surfaces of MRSA-positive and MRSA-negative patients respectively were contaminated with staphylococci at 08:00 hours, and that the staphylococcal concentrations increased by 80% at 1200 h over a 4-hour period with routine ward and clinical activities. Irrespective of the MRSA status of the patients, high-touch surfaces around the bed-units within the studied medical ward were heavily contaminated (ranged 1 to 276 cfu/cm2 amongst the sites with positive culture) with staphylococcal bacteria including MRSA, despite the implementation of daily hypochlorite wiping. However, the contamination rate dropped significantly from 78% to 11% after the application of the QAC polymer. In the experimental group, the mean staphylococcal concentration of bedside surfaces was significantly (p < 0.0001) reduced from 4.4 ± 8.7 cfu/cm2 at 08:00 hours to 0.07 ± 0.26 cfu/cm2 at 12:00 hours by the QAC polymer. The results of this study support the view that, in addition to hypochlorite wiping, the tested QAC surfactant is a potential environmental decontamination strategy for preventing the transmission of clinically important pathogens in medical wards.

Intensive care unit-acquired weakness.

Griffiths, Richard D; Hall, Jesse B

2010-03-01

Severe weakness is being recognized as a complication that impacts significantly on the pace and degree of recovery and return to former functional status of patients who survive the organ failures that mandate life-support therapies such as mechanical ventilation. Despite the apparent importance of this problem, much remains to be understood about its incidence, causes, prevention, and treatment. Review from literature and an expert round-table. The Brussels Round Table Conference in 2009 convened more than 20 experts in the fields of intensive care, neurology, and muscle physiology to review current understandings of intensive care unit-acquired weakness and to improve clinical outcome. Formal electrophysiological evaluation of patients with intensive care unit-acquired weakness can identify peripheral neuropathies, myopathies, and combinations of these disorders, although the correlation of these findings to weakness measurable at the bedside is not always precise. For routine clinical purposes, bedside assessment of neuromuscular function can be performed but is often confounded by complicating factors such as sedative and analgesic administration. Risk factors for development of intensive care unit-acquired weakness include bed rest itself, sepsis, and corticosteroid exposure. A strong association exists between weakness and long-term ventilator dependence; weakness is a major determinant of patient outcomes after surviving acute respiratory failure and may be present for months, or indefinitely, in the convalescence phase of critical illness. Although much has been learned about the physiology and cell and molecular biology of skeletal and diaphragm dysfunction under conditions of aging, exercise, disuse, and sepsis, the application of these understandings to the bedside requires more study in both bench models and patients. Although a trend toward greater immobilization and sedation of patients has characterized the past several decades of intensive care unit care, recent studies have demonstrated that early physical and occupational therapy, including during the period of intubation and ventilator support, can be safely performed and will likely improve patient outcomes with regard to functional status.

Abstract Background: Computer clinical decision support (CDS) systems are uncommon in the pediatric intensive care unit (PICU), despite evidence suggesting they improve outcomes in adult ICUs. We reasoned that a bedside CDS protocol for intravenous insulin titration, eProtocol-insulin, would be feasible and safe in critically ill children. Methods: We retrospectively reviewed data from non-diabetic children admitted to the PICU with blood glucose (BG) ≥140 mg/dL who were managed with intravenous insulin by either unaided clinician titration or eProtocol-insulin. Primary outcomes were BG measurements in target range (80–110 mg/dL) and severe hypoglycemia (BG ≤40 mg/dL); secondary outcomes were 60-day mortality and PICU length of stay. We assessed bedside nurse satisfaction with the eProtocol-insulin protocol by using a 5-point Likert scale and measured clinician compliance with eProtocol-insulin recommendations. Results: Over 5 years, 69 children were titrated with eProtocol-insulin versus 104 by unaided clinicians. eProtocol-insulin achieved target range more frequently than clinician titration (41% vs. 32%, P < 0.001). Severe hypoglycemia was uncommon in both groups (4.3% of patients in eProtocol-insulin, 8.7% in clinician titration, P = 0.37). There were no differences in mean time to BG target or median BG between the groups. Mortality was 23% in both groups. Clinician compliance with eProtocol-insulin recommendations was 89%. Nurses believed that eProtocol-insulin was easy to understand and safer than clinician titration. Conclusions: eProtocol-insulin is safe for titration of intravenous insulin in critically ill children. Clinical research protocols and quality improvement initiatives aimed at optimizing BG control should utilize detailed computer protocols that enable replicable clinician decisions. PMID:28248127

Examine the predictive value for maternal-fetal infection of routine bedside tests detecting the proinflammatory cytokines, TNFα and IL-6, in the vaginal secretions of women with premature rupture of the membranes (PROM). This prospective two-center cohort study included all women hospitalized for PROM over a 2-year period. A bedside test assessed IL-6 and TNFα in vaginal secretions. Both centers routinely tested CRP and leukocytes, assaying both in maternal serum, and analyzed vaginal bacterial flora; all samples were repeated twice weekly until delivery. The study included 689 women. In cases of preterm PROM (PPROM) before 37 weeks (n=184), a vaginal sample positive for one or more bacteria was the only marker associated with early neonatal infection (OR 5.6, 95%CI; 2.0-15.7). Its sensitivity was 82% (95%CI; 62-94) and its specificity 56% (95%CI; 47-65). All positive markers of infection were associated with the occurrence of chorioamnionitis. In cases of PROM from 37 weeks onward (n=505), only CRP >5mg/dL was associated with early neonatal infection (OR=8.3, 95%CI; 1.1-65.4) or clinical chorioamnionitis (OR=6.8, 95%CI; 1.5-30.0). The sensitivity of CRP >5mg/dL was 91% (95%CI; 59-100) and its specificity 45% (95%CI; 40-51) for predicting early neonatal infection, and 89% (95%CI; 65-99) and 46% (95%CI; 41-51), respectively, for predicting clinical chorioamnionitis. The association of vaginal cytokines with maternal-fetal infection is weak and thus prevents their use as a good predictor of maternal-fetal infection. CRP and vaginal samples may be useful for identifying a group of women at low risk of infection. Copyright © 2017 Elsevier B.V. All rights reserved.

Language barriers disrupt communication and impede informed consent for patients with limited English proficiency (LEP) undergoing healthcare procedures. Effective interventions for this disparity remain unclear. Assess the impact of a bedside interpreter phone system intervention on informed consent for patients with LEP and compare outcomes to those of English speakers. Prospective, pre-post intervention implementation study using propensity analysis. Hospitalized patients undergoing invasive procedures on the cardiovascular, general surgery or orthopedic surgery floors. Installation of dual-handset interpreter phones at every bedside enabling 24-h immediate access to professional interpreters. Primary predictor: pre- vs. post-implementation group; secondary predictor: post-implementation patients with LEP vs. English speakers. Primary outcomes: three central informed consent elements, patient-reported understanding of the (1) reasons for and (2) risks of the procedure and (3) having had all questions answered. We considered consent adequately informed when all three elements were met. We enrolled 152 Chinese- and Spanish-speaking patients with LEP (84 pre- and 68 post-implementation) and 86 English speakers. Post-implementation (vs. pre-implementation) patients with LEP were more likely to meet criteria for adequately informed consent (54% vs. 29%, p = 0.001) and, after propensity score adjustment, had significantly higher odds of adequately informed consent (AOR 2.56; 95% CI, 1.15-5.72) as well as of each consent element individually. However, compared to post-implementation English speakers, post-implementation patients with LEP had significantly lower adjusted odds of adequately informed consent (AOR, 0.38; 95% CI, 0.16-0.91). A bedside interpreter phone system intervention to increase rapid access to professional interpreters was associated with improvements in patient-reported informed consent and should be considered by hospitals seeking to improve care for patients with LEP; however, these improvements did not eliminate the language-based disparity. Additional clinician educational interventions and more language-concordant care may be necessary for informed consent to equal that for English speakers.

: To investigate whether a daily exercise session, using a bedside cycle ergometer, is a safe and effective intervention in preventing or attenuating the decrease in functional exercise capacity, functional status, and quadriceps force that is associated with prolonged intensive care unit stay. A prolonged stay in the intensive care unit is associated with muscle dysfunction, which may contribute to an impaired functional status up to 1 yr after hospital discharge. No evidence is available concerning the effectiveness of an early exercise training intervention to prevent these detrimental complications. : Randomized controlled trial. : Medical and surgical intensive care unit at University Hospital Gasthuisberg. : Ninety critically ill patients were included as soon as their cardiorespiratory condition allowed bedside cycling exercise (starting from day 5), given they still had an expected prolonged intensive care unit stay of at least 7 more days. : Both groups received respiratory physiotherapy and a daily standardized passive or active motion session of upper and lower limbs. In addition, the treatment group performed a passive or active exercise training session for 20 mins/day, using a bedside ergometer. : All outcome data are reflective for survivors. Quadriceps force and functional status were assessed at intensive care unit discharge and hospital discharge. Six-minute walking distance was measured at hospital discharge. No adverse events were identified during and immediately after the exercise training. At intensive care unit discharge, quadriceps force and functional status were not different between groups. At hospital discharge, 6-min walking distance, isometric quadriceps force, and the subjective feeling of functional well-being (as measured with "Physical Functioning" item of the Short Form 36 Health Survey questionnaire) were significantly higher in the treatment group (p < .05). : Early exercise training in critically ill intensive care unit survivors enhanced recovery of functional exercise capacity, self-perceived functional status, and muscle force at hospital discharge.

Administrative gatekeeping - a third way between unrestricted patient advocacy and bedside rationing.

PubMed

Lauridsen, Sigurd

2009-06-01

The inevitable need for rationing of healthcare has apparently presented the medical profession with the dilemma of choosing the lesser of two evils. Physicians appear to be obliged to adopt either an implausible version of traditional professional ethics or an equally problematic ethics of bedside rationing. The former requires unrestricted advocacy of patients but prompts distrust, moral hazard and unfairness. The latter commits physicians to rationing at the bedside; but it is bound to introduce unfair inequalities among patients and lack of political accountability towards citizens. In this paper I shall argue that this dilemma is false, since a third intermediate alternative exists. This alternative, which I term 'administrative gatekeeping', makes it possible for physicians to be involved in rationing while at the same time being genuine advocates of their patients. According to this ideal, physicians are required to follow fair rules of rationing adopted at higher organizational levels within healthcare systems. At the same time, however, they are prohibited from including considerations of cost in their clinical decisions.

Implementation of a locally developed evidence based nursing shift handover blueprint with a bedside-safety-check to determine the effect size on quality of handover. A mixed methods design with: (1) an interrupted time series analysis to determine the effect on handover quality in six domains; (2) descriptive statistics to analyze the intercepted discrepancies by the bedside-safety-check; (3) evaluation sessions to gather experiences with the new handover process. We observed a continued trend of improvement in handover quality and a significant improvement in two domains of handover: organization/efficiency and contents. The bedside-safety-check successfully identified discrepancies on drains, intravenous medications, bandages or general condition and was highly appreciated. Use of the nursing shift handover blueprint showed promising results on effectiveness as well as on feasibility and acceptability. However, to enable long term measurement on effectiveness, evaluation with large scale interrupted times series or statistical process control is needed. Copyright © 2016 Elsevier Inc.

Acute airway obstruction after hemoptysis occurs due to the presence of blood clots. These conditions may result in life-threatening ventilation impairment. We report a case of obstruction of the large airway by endobronchial blood clots which were removed using bronchoscopic cryotherapy at the bedside of intensive care unit. A 66-year-old female with endometrial cancer who had undergone chemotherapy, was admitted to the intensive care unit due to neutropenic fever. During mechanical ventilation, the minute ventilation dropped to inadequately low levels and chest radiography showed complete opacification of the left hemithorax. Flexible bronchoscopy revealed large blood clots obstructing the proximal left main bronchus. After unsuccessful attempts to remove the clots with bronchial lavage and forceps extraction, blood clots were removed using bronchoscopic cryotherapy. This report shows that cryotherapy via flexible bronchoscopy at the bedside in the intensive of intensive care unit is a simple and effective alternative for the removal of endobronchial blood clots.

The intent of this project was to create a formalized educational program for bedside nurses responsible for inpatient diabetes management. Bedside nurses are recruited to serve as diabetes management mentors. The mentors receive advanced education concerning teaching and learning principles, the AADE7™ Self-Care Behaviors, and diabetes management strategies. They teach their peers, advocate for patients, and facilitate referrals for outpatient Diabetes Self-Management Education (DSME) programs. The focus of these ongoing educational activities is to foster the development of diabetes management mentors and to create teaching tools that mentors can use with peers to address practice gaps or skill deficiencies. The diabetes management mentor is integral in enhancing the care of patients with diabetes in the hospital. The empowerment of bedside nurses as mentors for their peers and their patients is an invaluable asset that helps nurses take ownership of their practice. This role could be applied to other complex disease entities, helping nurses to develop specific management skills to improve patient outcomes and enhance patient satisfaction.

Point-of-care cardiac ultrasound techniques in the physical examination: better at the bedside.

PubMed

Kimura, Bruce J

2017-07-01

The development of hand-carried, battery-powered ultrasound devices has created a new practice in ultrasound diagnostic imaging, called 'point-of-care' ultrasound (POCUS). Capitalising on device portability, POCUS is marked by brief and limited ultrasound imaging performed by the physician at the bedside to increase diagnostic accuracy and expediency. The natural evolution of POCUS techniques in general medicine, particularly with pocket-sized devices, may be in the development of a basic ultrasound examination similar to the use of the binaural stethoscope. This paper will specifically review how POCUS improves the limited sensitivity of the current practice of traditional cardiac physical examination by both cardiologists and non-cardiologists. Signs of left ventricular systolic dysfunction, left atrial enlargement, lung congestion and elevated central venous pressures are often missed by physical techniques but can be easily detected by POCUS and have prognostic and treatment implications. Creating a general set of repetitive imaging skills for these entities for application on all patients during routine examination will standardise and reduce heterogeneity in cardiac bedside ultrasound applications, simplify teaching curricula, enhance learning and recollection, and unify competency thresholds and practice. The addition of POCUS to standard physical examination techniques in cardiovascular medicine will result in an ultrasound-augmented cardiac physical examination that reaffirms the value of bedside diagnosis. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Psychosocial job characteristics require nursing staff with high self-consistency and good mental health. However, the attention and effort of such study remained very limited in China. A self-administered questionnaire was distributed to the bedside nurses in an affiliated hospital of Hebei Medical University, China. Of 218 registered bedside nurses eligible to participate in the survey anonymously, the data producing sample of 172 subjects resulted in a 79 % of effective response rate.. The Social Support Rating Scale was used to measure social support, and the Self-Consistency and Congruence Scale were used to measure mental health. Compared with the normal referenced group of college students, higher self-flexibility scores, lower self-conflict and self-stethoscope scores from the sample group were obtained with statistical significance in self-conflict scores. The close correlations were observed between participants' social support and Self-Consistency and Congruence Scale score. The difference of Social Support Rating Scale score was significant in demographic features including years of work, marital status, only child family, and levels of cooperation with other health worker. Bedside nurses in this study show a better inner harmony, and their Self-Consistency and Congruence closely correlates with the levels of social support. Thus, it is substantial to improve inner perception of support and external factors, such as the workplace support, and offer beneficial social environment to improve the bedside nurse's sub-health symptoms and decrease the high turnover rate.

Explaining why nurses remain in or leave bedside nursing: a critical ethnography.

To describe the application of critical ethnography to explain nurses' decisions to remain in or leave bedside nursing, and to describe researcher positioning and reflexivity. Enquiry into hospital nurses' decisions to remain in or leave bedside nursing positions has been conducted from a variety of theoretical perspectives by researchers adopting a range of methodological approaches. This research helps to explain how work environments can affect variables such as job satisfaction and turnover, but provides less insight into how personal and professional factors shape decisions to remain in or leave bedside nursing. A critical theoretical perspective was taken to examine the employment decisions made by nurses in a paediatric intensive care unit (PICU). Data was collected from nurses (n=31) through semi-structured interviews and unobtrusive observation. The authors describe critical ethnography as a powerful research framework for enquiry that allowed them to challenge assumptions about why nurses remain in or leave their jobs, and to explore how issues of fairness and equity contribute to these decisions. Critical ethnography offers a powerful methodology for investigations into complex interactions, such as those between nurses in a PICU. In adopting this methodology, researchers should be sensitised to manifestations of power, attend to their stance and location, and reflexion. The greatest challenges from this research included how to make sense of the insider position, how to acknowledge assumptions and allow these to be challenged, and how to ensure that power relationships in the environment and in the research were attended to.

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 pitfalls including time complaints and the negative impact of physician indifference regarding this form of organ dysfunction.

Recent advances in functional neuroimaging have demonstrated novel potential for informing diagnosis and prognosis in the unresponsive wakeful syndrome and minimally conscious states. However, these technologies come with considerable expense and difficulty, limiting the possibility of wider clinical application in patients. Here, we show that high density electroencephalography, collected from 104 patients measured at rest, can provide valuable information about brain connectivity that correlates with behaviour and functional neuroimaging. Using graph theory, we visualize and quantify spectral connectivity estimated from electroencephalography as a dense brain network. Our findings demonstrate that key quantitative metrics of these networks correlate with the continuum of behavioural recovery in patients, ranging from those diagnosed as unresponsive, through those who have emerged from minimally conscious, to the fully conscious locked-in syndrome. In particular, a network metric indexing the presence of densely interconnected central hubs of connectivity discriminated behavioural consciousness with accuracy comparable to that achieved by expert assessment with positron emission tomography. We also show that this metric correlates strongly with brain metabolism. Further, with classification analysis, we predict the behavioural diagnosis, brain metabolism and 1-year clinical outcome of individual patients. Finally, we demonstrate that assessments of brain networks show robust connectivity in patients diagnosed as unresponsive by clinical consensus, but later rediagnosed as minimally conscious with the Coma Recovery Scale-Revised. Classification analysis of their brain network identified each of these misdiagnosed patients as minimally conscious, corroborating their behavioural diagnoses. If deployed at the bedside in the clinical context, such network measurements could complement systematic behavioural assessment and help reduce the high misdiagnosis rate reported in these patients. These metrics could also identify patients in whom further assessment is warranted using neuroimaging or conventional clinical evaluation. Finally, by providing objective characterization of states of consciousness, repeated assessments of network metrics could help track individual patients longitudinally, and also assess their neural responses to therapeutic and pharmacological interventions. © The Author (2017).

Memory Dysfunction

Matthews, Brandy R.

2015-01-01

Purpose of Review: This article highlights the dissociable human memory systems of episodic, semantic, and procedural memory in the context of neurologic illnesses known to adversely affect specific neuroanatomic structures relevant to each memory system. Recent Findings: Advances in functional neuroimaging and refinement of neuropsychological and bedside assessment tools continue to support a model of multiple memory systems that are distinct yet complementary and to support the potential for one system to be engaged as a compensatory strategy when a counterpart system fails. Summary: Episodic memory, the ability to recall personal episodes, is the subtype of memory most often perceived as dysfunctional by patients and informants. Medial temporal lobe structures, especially the hippocampal formation and associated cortical and subcortical structures, are most often associated with episodic memory loss. Episodic memory dysfunction may present acutely, as in concussion; transiently, as in transient global amnesia (TGA); subacutely, as in thiamine deficiency; or chronically, as in Alzheimer disease. Semantic memory refers to acquired knowledge about the world. Anterior and inferior temporal lobe structures are most often associated with semantic memory loss. The semantic variant of primary progressive aphasia (svPPA) is the paradigmatic disorder resulting in predominant semantic memory dysfunction. Working memory, associated with frontal lobe function, is the active maintenance of information in the mind that can be potentially manipulated to complete goal-directed tasks. Procedural memory, the ability to learn skills that become automatic, involves the basal ganglia, cerebellum, and supplementary motor cortex. Parkinson disease and related disorders result in procedural memory deficits. Most memory concerns warrant bedside cognitive or neuropsychological evaluation and neuroimaging to assess for specific neuropathologies and guide treatment. PMID:26039844

The severity of symptoms caused by atrial fibrillation (AF) is extremely variable. Quantifying the effect of AF on patient well-being is important but there is no simple, commonly accepted measure of the effect of AF on quality of life (QoL). Current QoL measures are cumbersome and impractical for clinical use. To create a simple, concise and readily usable AF severity score to facilitate treatment decisions and physician communication. The Canadian Cardiovascular Society (CCS) Severity of Atrial Fibrillation (SAF) Scale is analogous to the CCS Angina Functional Class. The CCS-SAF score is determined using three steps: documentation of possible AF-related symptoms (palpitations, dyspnea, dizziness/syncope, chest pain, weakness/fatigue); determination of symptom-rhythm correlation; and assessment of the effect of these symptoms on patient daily function and QoL. CCS-SAF scores range from 0 (asymptomatic) to 4 (severe impact of symptoms on QoL and activities of daily living). Patients are also categorized by type of AF (paroxysmal versus persistent/permanent). The CCS-SAF Scale will be validated using accepted measures of patient-perceived severity of symptoms and impairment of QoL and will require 'field testing' to ensure its applicability and reproducibility in the clinical setting. This type of symptom severity scale, like the New York Heart Association Functional Class for heart failure symptoms and the CCS Functional Class for angina symptoms, trades precision and comprehensiveness for simplicity and ease of use at the bedside. A common language to quantify AF severity may help to improve patient care.

Objective: To evaluate the feasibility and utility of instituting a formalized bedside skills evaluation (BSE) for 3rd-year medical students on the neurology clerkship. Methods: A neurologic BSE was developed for 3rd-year neurology clerks at the University of Rochester for the 2012–2014 academic years. Faculty directly observed 189 students completing a full history and neurologic examination on real inpatients. Mock grades were calculated utilizing the BSE in the final grade, and number of students with a grade difference was determined when compared to true grade. Correlation was explored between the BSE and clinical scores, National Board of Medical Examiners (NBME) scores, case complexity, and true final grades. A survey was administered to students to assess their clinical skills exposure and the usefulness of the BSE. Results: Faculty completed and submitted a BSE form for 88.3% of students. There was a mock final grade change for 13.2% of students. Correlation coefficients between BSE score and clinical score/NBME score were 0.36 and 0.35, respectively. A statistically significant effect of BSE was found on final clerkship grade (F2,186 = 31.9, p < 0.0001). There was no statistical difference between BSE score and differing case complexities. Conclusions: Incorporating a formal faculty-observed BSE into the 3rd year neurology clerkship was feasible. Low correlation between BSE score and other evaluations indicated a unique measurement to contribute to student grade. Using real patients with differing case complexity did not alter the grade.

Background: The arising challenges over endoscope reprocessing quality proposes to look for possibilities to measure and control the process of endoscope reprocessing. Aim: The goal of this study was to evaluate the feasibility of monitoring endoscope reprocessing with an adenosine triphosphate (ATP) based bioluminescence system. Methods: 60 samples of eight gastroscopes have been assessed from routine clinical use in a major university hospital in Germany. Endoscopes have been assessed with an ATP system and microbial cultures at different timepoints during the reprocessing. Findings: After the bedside flush the mean ATP level in relative light units (RLU) was 19,437 RLU, after the manual cleaning 667 RLU and after the automated endoscope reprocessor (AER) 227 RLU. After the manual cleaning the mean total viable count (TVC) per endoscope was 15.3 CFU/10 ml, and after the AER 5.7 CFU/10 ml. Our results show that there are reprocessing cycles which are not able to clean a patient used endoscope. Conclusion: Our data suggest that monitoring of flexible endoscope with ATP can identify a number of different influence factors, like the endoscope condition and the endoscopic procedure, or especially the quality of the bedside flush and manual cleaning before the AER. More process control is one option to identify and improve influence factors to finally increase the overall reprocessing quality, best of all by different methods. ATP measurement seems to be a valid technique that allows an immediate repeat of the manual cleaning if the ATP results after manual cleaning exceed the established cutoff of 200 RLU.

Critical ultrasound is a new tool for first-line physicians, including neonate intensivists. The consideration of the lung as one major target allows to redefine the priorities. Simple machines work better than up-to-date ones. We use a microconvex probe. Ten standardized signs allow a majority of uses: the bat sign (pleural line), lung sliding and the A-line (normal lung surface), the quad sign and sinusoid sign indicating pleural effusion regardless its echogenicity, the tissue-like sign and fractal sign indicating lung consolidation, the B-line artifact and lung rockets (indicating interstitial syndrome), abolished lung sliding with the stratosphere sign, suggesting pneumothorax, and the lung point, indicating pneumothorax. Other signs are used for more sophisticated applications (distinguishing atelectasis from pneumonia for instance...). All these disorders were assessed in the adult using CT as gold standard with sensitivity and specificity ranging from 90 to 100%, allowing to consider ultrasound as a reasonable bedside gold standard in the critically ill. The same signs are found, with no difference in the critically ill neonate. Fast protocols such as the BLUE-protocol are available, allowing immediate diagnosis of acute respiratory failure using seven standardized profiles. Pulmonary edema e.g. yields anterior lung rockets associated with lung sliding, making the B-profile. The FALLS-protocol, inserted in a Limited Investigation including a simple model of heart and vessels, assesses acute circulatory failure using lung artifacts. Interventional ultrasound (mainly, thoracocenthesis) provides maximal safety. Referrals to CT can be postponed. CEURF proposes personnalized bedside trainings since 1990. Lung ultrasound opens physicians to a visual medicine. PMID:23255876

Confocal mosaicing microscopy (CMM) enables rapid imaging of large areas of fresh tissue ex vivo without the processing that is necessary for conventional histology. When performed with fluorescence mode using acridine orange (nuclear specific dye) it enhances nuclei-to-dermis contrast that enables detection of all types of BCCs including thin strands of infiltrative basal cell carcinomas (BCCs). Thus far, this technique has been mostly validated in research setting for the analysis of BCC tumor margins. Recently, CMM has been adopted and implemented in real clinical settings by some surgeons as an alternative tool to frozen section (FS) during Mohs surgery. In this review article we summarize the development of CMM guided imaging of ex vivo tissues from bench to bedside. We also present its current state of application in routine clinical workflow not only for the assessment of BCC margin but also for other skin cancers such as melanoma, SCC, and some infectious diseases where FS is not routinely performed. Lastly, we also discuss the potential limitations of this technology as well as future developments. As this technology advances further, it may serve as an adjunct to standard histology and enable rapid surgical pathology of skin cancers at the bedside.

To describe the sequelae of oral endotracheal intubation by evaluating prevalence rates of structural injury, hyposalivation, and impaired vocal production over 14days following extubation. Consecutive adults (≥20years, N=114) with prolonged (≥48h) endotracheal intubation were enrolled from medical intensive care units at a university hospital. Participants were assessed by trained nurses at 2, 7, and 14days after extubation, using a standardized bedside screening protocol. Within 48-hour postextubation, structural injuries were common, with 51% having restricted mouth opening. Unstimulated salivary flow was reduced in 43%. For vocal production, 51% had inadequate breathing support for phonation, dysphonia was common (94% had hoarseness and 36% showed reduced efficiency of vocal fold closure), and >40% had impaired articulatory precision. By 14days postextubation, recovery was noted in most conditions, but reduced efficiency of vocal fold closure persisted. Restricted mouth opening (39%) and reduced salivary flow (34%) remained highly prevalent. After extubation, restricted mouth opening, reduced salivary flow, and dysphonia were common and prolonged in recovery. Reduced efficiency of vocal cord closure persisted at 14days postextubation. The extent and duration of these sequelae remind clinicians to screen for them up to 2weeks after extubation. Copyright © 2017 Elsevier Inc. All rights reserved.

Pathophysiologic mechanisms involved in neonatal hypoxic ischemic encephalopathy (HIE) are associated with complex changes of blood flow and metabolism. Therapeutic hypothermia (TH) is effective in reducing the extent of brain injury, but it remains uncertain how TH affects cerebral blood flow (CBF) and metabolism. Ten neonates undergoing TH for HIE and seventeen healthy controls were recruited from the NICU and the well baby nursery, respectively. A combination of frequency domain near infrared spectroscopy (FDNIRS) and diffuse correlation spectroscopy (DCS) systems was used to non-invasively measure cerebral hemodynamic and metabolic variables at the bedside. Results showed that cerebral oxygen metabolism (CMRO2i) and CBF indices (CBFi) in neonates with HIE during TH were significantly lower than post-TH and age-matched control values. Also, cerebral blood volume (CBV) and hemoglobin oxygen saturation (SO2) were significantly higher in neonates with HIE during TH compared with age-matched control neonates. Post-TH CBV was significantly decreased compared with values during TH whereas SO2 remained unchanged after the therapy. Thus, FDNIRS–DCS can provide information complimentary to SO2 and can assess individual cerebral metabolic responses to TH. Combined FDNIRS–DCS parameters improve the understanding of the underlying physiology and have the potential to serve as bedside biomarkers of treatment response and optimization. PMID:24064492

The aim of curriculum reform in medical education is to improve students' clinical and communication skills. However, there are contradicting results regarding the effectiveness of such reforms. A study of internal medicine students was carried out using a static group design. The experimental group consisted of 77 students participating in 7 sessions of communication training, 7 sessions of skills-laboratory training and 7 sessions of bedside-teaching, each lasting 1.5 hours. The control group of 66 students from the traditional curriculum participated in equally as many sessions but was offered only bedside teaching. Students' cognitive and practical skills performance was assessed using Multiple Choice Question (MCQ) testing and an objective structured clinical examination (OSCE), delivered by examiners blind to group membership. The experimental group performed significantly better on the OSCE than did the control group (P < 0.01), whereas the groups did not differ on the MCQ test (P < 0.15). This indicates that specific training in communication and basic clinical skills enabled students to perform better in an OSCE, whereas its effects on knowledge did not differ from those of the traditional curriculum. Curriculum reform promoting communication and basic clinical skills are effective and lead to an improved performance in history taking and physical examination skills.

A long history of use and extensive documentation of the clinical practices of traditional Chinese medicine resulted in a considerable number of classical preparations, which are still widely used. This heritage of our ancestors provides a unique resource for drug discovery. Already, a number of important drugs have been developed from traditional medicines, which in fact form the core of Western pharmacotherapy. Therefore, this article discusses the differences in drug development between traditional medicine and Western medicine. Moreover, the article uses the discovery of artemisinin as an example that illustrates the "bedside-bench-bedside" approach to drug discovery to explain that the middle way for drug development is to take advantage of the best features of these two distinct systems and compensate for certain weaknesses in each. This article also summarizes evidence-based traditional medicines and discusses quality control and quality assessment, the crucial steps in botanical drug development. Herbgenomics may provide effective tools to clarify the molecular mechanism of traditional medicines in the botanical drug development. The totality-of-the-evidence approach used by the U.S. Food and Drug Administration for botanical products provides the directions on how to perform quality control from the field throughout the entire production process.

The management of dysphagia requires a multidisciplinary approach, especially in large-scale hospitals. We introduce a novel protocol using a Wi-Fi-based flexible endoscopic evaluation of swallowing (FEES) system and aim to verify its effectiveness in evaluation and rehabilitation of inpatients with dysphagia. We conducted novel Wi-Fi-based FEES at the bedside using 3 iPads as monitors and recorders. Functional outcomes of swallowing in 2 different hospitals for acute care with conventional wired or wireless FEES were compared retrospectively. Using the wireless system, we could visit more patients in a short period of time. Furthermore, a large multidisciplinary team was able to be present at the bedside, which made it easy to hold discussions and rapidly devise appropriate rehabilitation strategies. Aspiration pneumonia recurred in a few cases following our intervention with wireless FEES. Functional oral intake score was significantly increased following the intervention. Moreover, the number of deaths during hospitalization using wireless FEES evaluation was lower than those observed using the conventional system. Wi-Fi-based wireless FEES system, the first of its kind, allowed our multidisciplinary team to easily and effectively assess inpatients with dysphagia by facilitating simple examinations and intensive transprofessional discussions for patient rehabilitation. © The Author(s) 2016.

Team Objective Structured Bedside Assessment (TOSBA) as formative assessment in undergraduate Obstetrics and Gynaecology: a cohort study.

Team Objective Structured Bedside Assessment (TOSBA) is a learning approach in which a team of medical students undertake a set of structured clinical tasks with real patients in order to reach a diagnosis and formulate a management plan and receive immediate feedback on their performance from a facilitator. TOSBA was introduced as formative assessment to an 8-week undergraduate teaching programme in Obstetrics and Gynaecology (O&G) in 2013/14. Each student completed 5 TOSBA sessions during the rotation. The aim of the study was to evaluate TOSBA as a teaching method to provide formative assessment for medical students during their clinical rotation. The research questions were: Does TOSBA improve clinical, communication and/or reasoning skills? Does TOSBA provide quality feedback? A prospective cohort study was conducted over a full academic year (2013/14). The study used 2 methods to evaluate TOSBA as a teaching method to provide formative assessment: (1) an online survey of TOSBA at the end of the rotation and (2) a comparison of the student performance in TOSBA with their performance in the final summative examination. During the 2013/14 academic year, 157 students completed the O&G programme and the final summative examination . Each student completed the required 5 TOSBA tasks. The response rate to the student survey was 68 % (n = 107/157). Students reported that TOSBA was a beneficial learning experience with a positive impact on clinical, communication and reasoning skills. Students rated the quality of feedback provided by TOSBA as high. Students identified the observation of the performance and feedback of other students within their TOSBA team as key features. High achieving students performed well in both TOSBA and summative assessments. The majority of students who performed poorly in TOSBA subsequently passed the summative assessments (n = 20/21, 95 %). Conversely, the majority of students who failed the summative assessments had satisfactory scores in TOSBA (n = 6/7, 86 %). TOSBA has a positive impact on the clinical, communication and reasoning skills of medical students through the provision of high-quality feedback. The use of structured pre-defined tasks, the observation of the performance and feedback of other students and the use of real patients are key elements of TOSBA. Avoiding student complacency and providing accurate feedback from TOSBA are on-going challenges.

Ad hoc versus standardized admixtures for continuous infusion drugs in neonatal intensive care: cognitive task analysis of safety at the bedside.

Continuous infusion intravenous (IV) drugs in neonatal intensive care are usually prepared based on patient weight so that the dose is readable as a simple multiple of the infusion pump rate. New safety guidelines propose that hospitals switch to using standardized admixtures of these drugs to prevent calculation errors during ad hoc preparation. Extended hierarchical task analysis suggests that switching to standardized admixtures may lead to more errors in programming the pump at the bedside.

Bedside nurses in the critical care setting deal with death on a regular basis. Historically, end-of-life decision making has been addressed by physicians with the family and patient, yet nurses may be a better resource for families during the decision-making process. The purpose of this article was to provide a brief review of literature surrounding end-of-life decision making. As patient advocates, nurses should be more actively involved with facilitating the end-of-life decision-making process for critically ill patients and their families.

The architecture further supports automatical data input from medical devices. First results from three different intensive care units are reported. PMID:8947771

Promoting safer blood transfusion practice in hospital.

PubMed

Parris, E; Grant-Casey, J

Results from a national comparative audit of bedside transfusion practice show that patients in the UK are at risk of misidentification and poor monitoring when undergoing a blood transfusion. A commonly identified reason for poor compliance with guidelines from the British Committee for Standards in Haematology (BCSH et al 1999) is a lack of awareness of good transfusion practice (National Blood Service (NBS) 2005). This article discusses the implications of the audit findings for the administration of blood at the bedside and examines initiatives to support hospital staff in their efforts to improve blood transfusion safety.

The nursing perspective on monitoring hemodynamics and oxygen transport.

Tucker, Dawn; Hazinski, Mary Fran

2011-07-01

Maintenance of adequate systemic oxygen delivery requires careful clinical assessment integrated with hemodynamic measurements and calculations to detect and treat conditions that may compromise oxygen delivery and lead to life-threatening shock, respiratory failure, or cardiac arrest. The bedside nurse constantly performs such assessments and measurements to detect subtle changes and trends in patient condition. The purpose of this editorial is to highlight nursing perspectives about the hemodynamic and oxygen transport monitoring systems summarized in the Pediatric Cardiac Intensive Care Society Evidence- Based Review and Consensus Statement on Monitoring of Hemodynamics and Oxygen Transport Balance. There is no substitute for the observations of a knowledgeable and experienced clinician who understands the patient's condition and potential causes of deterioration and is able to evaluate response to therapy.

The study aims to investigate the associated factors of on-call physician workload based on a published conceptual framework. The study was conducted in a general internal medicine unit of National Taiwan University Hospital. On-call physician workloads were recorded on a shift basis from 1198 hospitalized patients between May 2010 and April 2011. The proxy of on-call workloads included night calls, bedside evaluation/management (E/M), and performing clinical procedures in a shift. Multivariable logistic and negative binomial regression models were used to determine the factors associated with the workloads of on-call physicians. During the study period, 378 (31.6%) of patients had night calls with related workloads. Multivariate analysis showed that the number of patients with unstable conditions in a shift (odds ratio [OR] 1.89 and 1.66, respectively) and the intensive care unit (ICU) training of the nurse leader (OR 2.87 and 3.08, respectively) resulted in higher likelihood of night calls to and bedside E/M visits by the on-call physician. However, ICU training of nurses (OR = 0.37, 95% confidence interval: 0.16–0.86) decreased the demand of performing clinical procedures by the on-call physician. Moreover, number of patients with unstable conditions (risk ratio [RR] 1.52 and 1.55, respectively) had significantly increased the number of night calls and bedside E/M by on-call physicians by around 50%. Nurses with N1 level (RR 2.16 and 2.71, respectively) were more likely to place night calls and facilitate bedside E/M by the on-call physician compared to nurses with N0 level. In addition, the nurse leaders with ICU training (RR 1.72 and 3.07, respectively) had significant increases in night calls and bedside E/M by the on-call physician compared to those without ICU training. On-call physician workload is associated with patient factors and the training of nurses. Number of unstable patients in a shift may be considered in predicting workload. The training of nurses may improve patient safety and decrease demand for clinical procedure. PMID:27583910

The severe pain related to repeated burn dressing changes at bedside is often difficult to manage. However these dressings can be performed at bedside on spontaneously breathing non-intubated patients using powerful intravenous opioids with a quick onset and a short duration of action such as alfentanil. The purpose of this study is to demonstrate the efficacy and safety of the protocol which is used in our burn unit for pain control during burn dressing changes. Cohort study began after favorable opinion from local ethic committee has been collected. Patient's informed consent was collected. No fasting was required. Vital signs for patients were continuously monitored (non-invasive blood pressure, ECG monitoring, cutaneous oxygen saturation, respiratory rate) all over the process. Boluses of 500 (±250) mcg IV alfentanil were administered. A continuous infusion was added in case of insufficient analgesia. Adverse reactions were collected and pain intensity was measured throughout the dressing using a ten step verbal rating scale (VRS) ranging from 0 (no pain) to 10 (worst pain conceivable). 100 dressings (35 patients) were analyzed. Median age was 45 years and median burned area 10%. We observed 3 blood pressure drops, 5 oxygen desaturations (treated with stimulation without the necessity of ventilatory support) and one episode of nausea. Most of the patients (87%) were totally conscious during the dressing and 13% were awakened by verbal stimulation. Median total dose of alfentanil used was 2000μg for a median duration of 35min. Pain scores during the procedure were low or moderate (VRS mean=2.0 and maximal VRS=5). Median satisfaction collected 2h after the dressing was 10 on a ten step scale. Pain control with intravenous alfentanil alone is efficient and appears safe for most burn bedside repeated dressings in hospitalized patients. It achieves satisfactory analgesia during and after the procedure. It is now our standard analgesic method to provide repeated bedside dressings changes for burned patients.

The use of the oesophageal Doppler in perioperative medicine: new opportunities in research and clinical practice.

PubMed

Pinto, Bernardo Bollen; Atlas, Glen; Geerts, Bart F; Bendjelid, Karim

The oesophageal Doppler (OD) is a minimally invasive haemodynamic monitor used in the surgical theatre and the ICU. Using the OD, goal-directed therapy (GDT) has been shown to reduce perioperative complications in high-risk surgical patients. However, most GDT protocols currently in use are limited to stroke volume optimisation. In the present manuscript, we examine the conceptual models behind new OD-based measurements. These would provide the clinician with a comprehensive view of haemodynamic pathophysiology; including pre-load, contractility, and afterload. Specifically, volume status could be estimated using mean systemic filling pressure (MSFP), the pressure to which all intravascular pressures equilibrate during asystole. Using the OD, MSFP could be readily estimated by simultaneous measurements of aortic blood flow and arterial pressure with sequential manoeuvres of increasing airway pressure. This would result in subsequent reductions in cardiac output and arterial pressure and would allow for a linear extrapolation of a static MSFP value to a "zero flow" state. In addition, we also demonstrate that EF is proportional to mean blood flow velocity measured in the descending thoracic aorta with the OD. Furthermore, OD-derived indexes of blood flow velocity and acceleration, as well as force and kinetic energy, can be derived and used for continuous assessment of cardiac contractility at the bedside. Using OD-derived parameters, the different components of afterload: inertia, resistance and elastance, could also be individually determined. The integration of these additional haemodynamic parameters could assist the clinician in optimising and individualising haemodynamic performance in unstable patients.

Acquisition of ICU data: concepts and demands.

PubMed

Imhoff, M

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)

Alternatives for the Bedside Schwartz Equation to Estimate Glomerular Filtration Rate in Children.

The bedside Schwartz equation has long been and still is the recommended equation to estimate glomerular filtration rate (GFR) in children. However, this equation is probably best suited to estimate GFR in children with chronic kidney disease (reduced GFR) but is not optimal for children with GFR >75 mL/min/1.73 m 2 . Moreover, the Schwartz equation requires the height of the child, information that is usually not available in the clinical laboratory. This makes automatic reporting of estimated glomerular filtration rate (eGFR) along with serum creatinine impossible. As the majority of children (even children referred to nephrology clinics) have GFR >75 mL/min/1.73 m 2 , it might be interesting to evaluate possible alternatives to the bedside Schwartz equation. The pediatric form of the Full Age Spectrum (FAS) equation offers an alternative to Schwartz, allowing automatic reporting of eGFR since height is not necessary. However, when height is involved in the FAS equation, the equation is essentially equal to the Schwartz equation for children, but there are large differences for adolescents. Combining standardized biomarkers increases the prediction performance of eGFR equations for children, reaching P10 ≈ 45% and P30 ≈ 90%. There are currently good and simple alternatives to the bedside Schwartz equation, but the more complex equations combining serum creatinine, serum cystatin C, and height show the highest accuracy and precision.

As the conversion to an electronic health record intensifies, the question of which data-entry device works best in what environment and situation is paramount. Specifically, what is the best mix of equipment to purchase and install on clinical units based on staff preferences and budget constraints? The authors discuss their evaluation of stationary personal computers, workshops on wheels, and handheld tablets related to timeliness of data entry and their use of focus groups to ascertain the pros/cons of data-entry devices and staff preferences. An assessment of the implications for costs related to the timeliness of data entry is also presented.

Errors related to blood transfusion in hospitals may produce catastrophic consequences. This review addresses potential solutions to prevent patient misidentification including the use of new technology, such as barcoding. A small number of studies using new technology for the transfusion process in hospitals have shown promising results in preventing errors. The studies demonstrated improved transfusion safety and staff preference for new technology such as bedside handheld scanners to carry out pretransfusion bedside checking. They also highlighted the need for considerable efforts in the training of staff in the new procedures before their successful implementation. Improvements in hospital transfusion safety are a top priority for transfusion medicine, and will depend on a combined approach including a better understanding of the causes of errors, a reduction in the complexity of routine procedures taking advantage of new technology, improved staff training, and regular monitoring of practice. The use of new technology to improve the safety of transfusion is very promising. Further development of the systems is needed to enable staff to carry out bedside transfusion procedures quickly and accurately, and to increase their functionality to justify the cost of their wider implementation.

Bioethics is a relatively new addition to bedside medical care in Arab world which is characterized by a special culture that often makes blind adaptation of western ethics codes and principles; a challenge that has to be faced. To date, the American University of Beirut Medical Center is the only hospital that offers bedside ethics consultations in the Arab Region aiming towards better patient-centered care. This article tackles the role of the bedside clinical ethics consultant as an active member of the medical team and the impact of such consultations on decision-making and patient-centered care. Using the case of a child with multiple medical problems and a futile medical condition, we describe how the collaboration of the medical team and the clinical ethics consultant took a comprehensive approach to accompany and lead the parents and the medical team in their decision-making process and how the consultations allowed several salient issues to be addressed. This approach proved to be effective in the Arab cultural setting and indeed did lead to better patientcentered care. © 2018 John Wiley & Sons Ltd.

Several new approaches for treatment of Central Nervous System (CNS) disorders are currently under investigation, including the use of rehabilitation training strategies, which are often combined with electrical and/or pharmacological modulation of spinal locomotor circuitries. While these approaches show great promise in the laboratory setting, there still exists a large gap in knowledge on how to transfer these treatments to daily clinical use. This thematic series presents a cross section of cutting edge approaches with the goal of transferring basic neuroscience principles from the laboratory to the proverbial "bedside".

To design and implement an emergency medicine (EM) postgraduate training curriculum to support the establishment of the first EM residency program at Addis Ababa University (AAU). In response to the Ethiopian Federal Ministry of Health mandate to develop EM services in Ethiopia, University of Toronto EM faculty were invited to develop and deliver EM content and expertise for the first EM postgraduate residency training program at AAU. The Toronto Addis Ababa Academic Collaboration-EM (TAAAC-EM) used five steps of a six-step approach to guide curriculum development and implementation: 1. Problem identification and general needs assessment, 2. Targeted needs assessment using indirect methods (interviews and site visits of the learners and learning environment), 3. Defining goals and objectives, 4. Choosing educational strategies and curriculum map development and 5. The needs assessment identified a learning environment with appropriate, though limited, resources for the implementation of an EM residency program. A lack of educational activities geared towards EM practice was identified, specifically of active learning techniques (ALTs) such as bedside teaching, simulation and procedural teaching. A curriculum map was devised to supplement the AAU EM residency program curriculum. The TAAAC-EM curriculum was divided into three distinct streams: clinical, clinical epidemiology and EM administration. The clinical sessions were divided into didactic and ALTs including practical/procedural and simulation sessions, and bedside teaching was given a strong emphasis. Implementation is currently in its seventh year, with continuous monitoring and revisions of the curriculum to meet evolving needs. We have outlined the design and implementation of the TAAAC-EM curriculum; an evaluation of this curriculum is currently underway. As EM spreads as a specialty throughout Africa and other resource-limited regions, this model can serve as a working guide for similar bi-institutional educational partnerships seeking to develop novel EM postgraduate training programs.

To determine the effect of a 2-yr multifaceted program aimed at preventing ventilator-acquired pneumonia on compliance with eight targeted preventive measures. Pre- and postintervention observational study. A 20-bed medical intensive care unit in a teaching hospital. A total of 1649 ventilator-days were observed. The program involved all healthcare workers and included a multidisciplinary task force, an educational session, direct observations with performance feedback, technical improvements, and reminders. It focused on eight targeted measures based on well-recognized published guidelines, easily and precisely defined acts, and directly concerned healthcare workers' bedside behavior. Compliance assessment consisted of five 4-wk periods (before the intervention and 1 month, 6 months, 12 months, and 24 months thereafter). Hand-hygiene and glove-and-gown use compliances were initially high (68% and 80%) and remained stable over time. Compliance with all other preventive measures was initially low and increased steadily over time (before 2-yr level, p < .0001): backrest elevation (5% to 58%) and tracheal cuff pressure maintenance (40% to 89%), which improved after simple technical equipment implementation; orogastric tube use (52% to 96%); gastric overdistension avoidance (20% to 68%); good oral hygiene (47% to 90%); and nonessential tracheal suction elimination (41% to 92%). To assess overall performance of the last six preventive measures, using ventilator-days as the unit of analysis, a composite score for preventive measures applied (range, 0-6) was developed. The median (interquartile range) composite scores for the five successive assessments were 2 (1-3), 4 (3-5), 4 (4-5), 5 (4-6), and 5 (4-6) points; they increased significantly over time (p < .0001). Ventilator-acquired pneumonia prevalence rate decreased by 51% after intervention (p < .0001). Our active, long-lasting program for preventing ventilator-acquired pneumonia successfully increased compliance with preventive measures directly dependent on healthcare workers' bedside performance. The multidimensional framework was critical for this marked, progressive, and sustained change.

Failure to transfer procedural skills learned in a laboratory to the bedside is commonly due to a lack of peer support/stimulation. A digital platform (Facebook) allows new clinical clerks to share experiences and tips that help augment their procedural skills in a peer-assisted learning/teaching method. This study aims to investigate the effectiveness of the innovation of using the digital platform to support the transfer of laboratory-trained procedural skills in the clinical units. Volunteer clinical clerks (n = 44) were enrolled into the peer-assisted learning (PAL) group, which was characterized by the peer-assisted learning of procedural skills during their final 3-month clinical clerkship block. Other clerks (n = 51) did not join the procedural skills-specific Facebook group and served as the self-directed learning regular group. The participants in both the PAL and regular groups completed pre- and post-intervention self-assessments for general self-assessed efficiency ratings (GSER) and skills specific self-assessed efficiency ratings (SSSER) for performing vein puncture, intravenous (IV) catheter and nasogastric (NG) tube insertion. Finally, all clerks received the post-intervention 3-station Objective Structured Clinical Skills Examination (OSCE) to test their proficiency for the abovementioned three procedural skills. Higher cumulative numbers of vein punctures, IV catheter insertions and NG tube insertions at the bedside were carried out by the PAL group than the regular group. A greater improvement in GSERs and SSSERs for medical procedures was found in the PAL group than in the regular group. The PAL group obtained higher procedural skills scores in the post-intervention OSCEs than the regular group. Our study suggested that the implementation of a procedural skill-specific digital platform effectively helps clerks to transfer laboratory-trained procedural skills into the clinical units. In comparison with the regular self-directed learning group, the peer-assisted learning characteristics of Facebook give additional benefits to the PAL group by enhancing their procedural skills.

Acute kidney injury (AKI) is an important clinical issue, especially in the setting of critical care. It has been shown in multiple studies to be a key independent risk factor for mortality, even after adjustment for demographics and severity of illness. There is wide agreement that a generally applicable classification system is required for AKI which helps to standardize estimation of severity of renal disfunction and to predict outcome associated with this condition. That's how RIFLE (Risk-Injury-Failure-Loss-End-stage renal disease), and AKIN (Acute Kidney Injury Network) classifications for AKI were found in 2004 and 2007, respectively. In the clinical setting of heart failure, a positive fluid balance (often expressed in the literature as weight gain) is used by disease management programs as a marker of heart failure decompensation. Oliguria is defined as urine output less than 0,3 ml/kg/h for at least 24 h. Since any delay in treatment can lead to a dangerous progression of the AKI, early recognition of oliguria appears to be crucial. Critically ill patients with oliguric AKI are at increased risk for fluid imbalance due to widespread systemic inflammation, reduced plasma oncotic pressure and increased capillary leak. These patients are particulary at risk of fluid overload and therefore restrictive strategy of fluid administration should be used. Objective, rapid and accurate volume assessment is important in undiagnosed patients presenting with critical illness, as errors may result in interventions with fatal outcomes. The historical tools such as physical exam, and chest radiography suffer from significant limitations. As gold standard, radioisolopic measurement of volume is impractical in the acute care enviroment. Newer technologies offer the promise of both rapid and accurate bedside estimation of volume status with the potential to improve clinical outcomes. Blood assessment with bioimpendance vector analysis, and bedside ultrasound seem to be promising technologies for this need.

The measurement of brain perfusion may provide valuable information for assessment and treatment of newborns with hypoxic-ischemic encephalopathy (HIE). While arterial spin labeled perfusion (ASL) magnetic resonance imaging (MRI) provides noninvasive and direct measurements of regional cerebral blood flow (CBF) values, it is logistically challenging to obtain. Near-infrared spectroscopy (NIRS) might be an alternative, as it permits noninvasive and continuous monitoring of cerebral hemodynamics and oxygenation at the bedside. The purpose of this study is to determine the correlation between measurements of brain perfusion by NIRS and by MRI in term newborns with HIE treated with hypothermia. In this prospective cohort study, ASL-MRI and NIRS performed during hypothermia were used to assess brain perfusion in these newborns. Regional cerebral blood flow (CBF) values, measured from 1-2 MRI scans for each patient, were compared to mixed venous saturation values (SctO2) recorded by NIRS just before and after each MRI. Analysis included groupings into moderate versus severe HIE based on their initial background pattern of amplitude-integrated electroencephalogram. Twelve concomitant recordings were obtained of seven neonates. Strong correlation was found between SctO2 and CBF in asphyxiated newborns with severe HIE (r=0.88; p value=0.0085). Moreover, newborns with severe HIE had lower CBF (likely lower oxygen supply) and extracted less oxygen (likely lower oxygen demand or utilization) when comparing SctO2 and CBF to those with moderate HIE. NIRS is an effective bedside tool to monitor and understand brain perfusion changes in term asphyxiated newborns, which in conjunction with precise measurements of CBF obtained by MRI at particular times, may help tailor neuroprotective strategies in term newborns with HIE.

ABSTRACT Background: predicting the development of severe disease has remained a major challenge in management of acute pancreatitis. The Bedside Index for Severity in Acute Pancreatitis (BISAP) is easy to calculate from the data available in the first 24 hours. Here, we performed a systematic review to determine the prognostic accuracy of the BISAP for severe acute pancreatitis (SAP). Methods: major databases of biomedical publications were searched during the first week of October 2015. Two independent reviewers searched records in two phases. Studies that reported prognostic accuracy of the BISAP for SAP from prospective cohorts were included. The pooled area under the receiver operating curve (AUC) was calculated. Results: Twelve studies were included for data-synthesis and methodology quality assessment was performed for 10. All the studies had enrolled consecutive patients, had a broad spectrum of the disease severity, reported explicit interpretation of the predictor, outcome of interest was well defined and had adequate follow-up. Blinded outcome assessment was reported in only one study. The pooled AUC was 0.85 (95% CI 0.80–0.90). There was significant heterogeneity, I 2 86.6%. Studies using revised Atlanta classification in defining SAP had a pooled AUC of 0.92 (95% CI, 0.90–0.95), but heterogeneity persisted, I 2 67%. Subgroup analysis based on rate of SAP (>20% vs <20%) did not eliminate the heterogeneity. Conclusion: the BISAP has very good predictive performance for SAP across different patient population and etiologies. Studies to evaluate the impact of incorporating the BISAP into clinical practice to improve outcome in acute pancreatitis are needed before adoption could be advocated with confidence. PMID:29046745

New biochemical markers: from bench to bedside.

Evaluation of patients presenting to hospital with chest pain or other signs or symptoms suggesting acute coronary syndrome (ACS) is problematic, time-consuming and sometimes expensive, even if new biochemical markers, such as troponins, have improved the ability to detect cardiac injury. However, patients with normal troponin values are not necessarily risk-free for major cardiac events. Recent investigations indicate that the overall patient risk may be assessed earlier than before, thanks to new knowledge acquired concerning the pathobiology of atherosclerosis and molecular events involved in the progression of disease, thus allowing the development of new biochemical markers. Some selected markers are released during the different phases of development of cardiovascular disease and may be useful for the diagnosis of patients with cardiovascular disease. In particular, the identification of emerging markers that provide relevant information on the inflammatory process, and the development of biomarkers whose circulating concentrations suggest the status of plaque instability and rupture, seems to be of particular value in prognosis and risk stratification. The overall expectations for a cardiovascular biochemical marker are not only its biological plausibility but also the availability at a reasonable cost of rapid, high quality assays, and their correct interpretation by clinicians using optimal cut-offs. The crossing from bench to bedside for each new marker discovered, must be associated with concurrent advances in the characterization of analytical features and the development of routine assay, in the assessment of analytical performance and in interpretative reporting of test results as well as in the training of physicians to use the array of biomarkers available appropriately and to interpret them correctly. This approach calls for the coordinated support of clinicians, technology experts, statisticians and the industry so that new biochemical developments can be of optimal value.

To assess the current training in brain death examination provided during pediatric critical care medicine fellowship. Internet-based survey. United States pediatric critical care medicine fellowship programs. Sixty-four pediatric critical care medicine fellowship program directors and 230 current pediatric critical care medicine fellows/recent graduates were invited to participate. Participants were asked demographic questions related to their fellowship programs, training currently provided at their fellowship programs, previous experience with brain death examinations (fellows/graduates), and perceptions regarding the adequacy of current training. Twenty-nine program directors (45%) and 91 current fellows/graduates (40%) responded. Third-year fellows reported having performed a median of five examinations (interquartile range, 3-6). On a five-point Likert scale, 93% of program directors responded they "agree" or "strongly agree" that their fellows receive enough instruction on performing brain death examinations compared with 67% of fellows and graduates (p = 0.007). The responses were similar when asked about opportunity to practice brain death examinations (90% vs 54%; p < 0.001). In a regression tree analysis, number of brain death examinations performed was the strongest predictor of trainee satisfaction. Both fellows and program directors preferred bedside demonstration or simulation as educational modalities to add to the fellowship curriculum. Pediatric critical care medicine fellows overall perform relatively few brain death examinations during their training. Pediatric critical care medicine fellows and program directors disagree in their perceptions of the current training in brain death examination, with fellows perceiving a need for increased training. Both program directors and fellows prefer additional training using bedside demonstration or simulation. Since clinical exposure to brain death examinations is variable, adding simulated brain death examinations to the pediatric critical care medicine fellowship curriculum could help standardize the experience.

In a 15-month American Organization of Nurse Executives collaborative involving frontline medical/surgical staff from 67 hospitals, Transforming Care at the Bedside (TCAB) was evaluated to assess whether participating units successfully implemented recommended change processes, engaged staff, implemented innovations, and generated support from hospital leadership and staff. In a mixed-methods analysis, multiple data sources, including leader surveys, unit staff surveys, administrative data, time study data, and collaborative documents were used. All units reported establishing unit-based teams, of which >90% succeeded in conducting tests of change, with unit staff selecting topics and making decisions on adoption. Fifty-five percent of unit staff reported participating in unit meetings, and 64%, in tests of change. Unit managers reported substantial increase in staff support for the initiative. An average 36 tests of change were conducted per unit, with 46% of tested innovations sustained, and 20% spread to other units. Some 95% of managers and 97% of chief nursing officers believed that the program had made unit staff more likely to initiate change. Among staff, 83% would encourage adoption of the initiative. Given the strong positive assessment of TCAB, evidence of substantial engagement of staff in the work, and the high volume of innovations tested, implemented, and sustained, TCAB appears to be a productive model for organizing and implementing a program of frontline-led improvement.

To determine whether noninvasive hemoglobin measurement by Pulse CO-Oximetry could provide clinically acceptable absolute and trend accuracy in critically ill patients, compared to other invasive methods of hemoglobin assessment available at bedside and the gold standard, the laboratory analyzer. Prospective study. Surgical intensive care unit of a university teaching hospital. Sixty-two patients continuously monitored with Pulse CO-Oximetry (Masimo Radical-7). None. Four hundred seventy-one blood samples were analyzed by a point-of-care device (HemoCue 301), a satellite lab CO-Oximeter (Siemens RapidPoint 405), and a laboratory hematology analyzer (Sysmex XT-2000i), which was considered the reference device. Hemoglobin values reported from the invasive methods were compared to the values reported by the Pulse CO-Oximeter at the time of blood draw. When the case-to-case variation was assessed, the bias and limits of agreement were 0.0±1.0 g/dL for the Pulse CO-Oximeter, 0.3±1.3g/dL for the point-of-care device, and 0.9±0.6 g/dL for the satellite lab CO-Oximeter compared to the reference method. Pulse CO-Oximetry showed similar trend accuracy as satellite lab CO-Oximetry, whereas the point-of-care device did not appear to follow the trend of the laboratory analyzer as well as the other test devices. When compared to laboratory reference values, hemoglobin measurement with Pulse CO-Oximetry has absolute accuracy and trending accuracy similar to widely used, invasive methods of hemoglobin measurement at bedside. Hemoglobin measurement with pulse CO-Oximetry has the additional advantages of providing continuous measurements, noninvasively, which may facilitate hemoglobin monitoring in the intensive care unit.

Blood stem cells and non-hematological clinical practice: pragmatics before therapeutics.

There is considerable interest in biological sources for replacement, repair, as well as vascularization of tissue. The remarkable properties of blood stem cells encourage interest in their therapeutic potential. But what are these properties, and how do they influence their clinical potential and the advisability of stem cell use as a therapeutic resource? Rational assessment of the significance of in vitro and animal in vivo data should precede the rush from the bench to the bedside. Basic stem cell research is rife with examples where the truth of the subsequently demonstrated mechanism is stranger than the initial interpretation proved fiction. This review will assess tissue contribution by different blood related stem cells, differing possible mechanisms underlying observed repair phenomena, and consider the potency and pitfalls of stem cell therapeutics.

Neonatal hypoglycemia may cause severe neurological damages; therefore, tight glycemic control is crucial to identify neonate at risk. Previous blood glucose monitoring system (BGMS) failed to perform well in neonates; there are calls for the tightening of accuracy requirements. It remains a need for accurate BGMS for effective bedside diabetes management in neonatal care within a hospital population. A total of 300 neonates were recruited from local hospitals. Accuracy performance of a commercially available BGMS was evaluated against reference instrument in screening for neonatal hypoglycemia, and assessment was made based on the ISO15197:2013 and a tighter standard. At blood glucose level < 47 mg/dl, BGMS assessed met the minimal accuracy requirement of ISO 15197:2013 and tighter standard at 100% and 97.2%, respectively.

How to choose the therapeutic goals to improve tissue perfusion in septic shock

2015-01-01

The early recognition and treatment of severe sepsis and septic shock is the key to a successful outcome. The longer the delay in starting treatment, the worse the prognosis due to persistent tissue hypoperfusion and consequent development and worsening of organ dysfunction. One of the main mechanisms responsible for the development of cellular dysfunction is tissue hypoxia. The adjustments necessary for adequate tissue blood flow and therefore of oxygen supply to metabolic demand according to the assessment of the cardiac index and oxygen extraction rate should be performed during resuscitation period, especially in high complexity patients. New technologies, easily handled at the bedside, and new studies that directly assess the impact of macro-hemodynamic parameter optimization on microcirculation and in the clinical outcome of septic patients, are needed.

Newborns requiring hospitalisation frequently undergo painful procedures. Prevention of pain in infants is of prime concern because of adverse associations with physiological and neurological development. However, pain mitigation is currently guided by behavioural observation assessments that have not been validated against direct evidence of pain processing in the brain. The aim of this study was to determine whether cry presence or amplitude is a valid indicator of pain processing in newborns. Prospective observational cohort. Newborn nursery. Healthy infants born at >37 weeks and <42 weeks gestation. We prospectively studied newborn cortical responses to light touch, cold and heel stick, and the amplitude of associated infant vocalisations using our previously published paradigms of time-locked electroencephalogram (EEG) with simultaneous audio recordings. Latencies of cortical peak responses to each of the three stimuli type were significantly different from each other. Of 54 infants, 13 (24%), 19 (35%) and 35 (65%) had cries in response to light touch, cold and heel stick, respectively. Cry in response to non-painful stimuli did not predict cry in response to heel stick. All infants with EEG data had measurable pain responses to heel stick, whether they cried or not. There was no association between presence or amplitude of cries and cortical nociceptive amplitudes. In newborns with distinct brain responses to light touch, cold and pain, cry presence or amplitude characteristics do not provide adequate behavioural markers of pain signalling in the brain. New bedside assessments of newborn pain may need to be developed using brain-based methodologies as benchmarks in order to provide optimal pain mitigation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Francis (2013) described inconsistent ward rounds and failures to conduct ward rounds properly as contributing factors to the poor care seen at the Mid Staffordshire Foundation Trust. He suggested that the absence of a nurse at the bedside had clear consequences for communication, ward round efficiency and patient safety. He recommended that nurses should be actively involved in ward rounds and linked this to high quality patient care. To share an experience of introducing a ward round checklist, a bedside nurse verbal summary and the development of standard operating procedure for Ward Rounds in cardiothoracic critical care unit to improve patient safety and care. Semi structured interviews of six registered nurses. A questionnaire to 69 registered nurses. An electronic questionnaire sent to 23 members of the MDT. An observational audit of seven ward rounds reviewing 69 patients. 97% of nurses agreed that verbal summarizing had improved clarity and 90% felt that it had improved patient care. 87% of the MDT respondents stated that they had noticed an improvement in the attendance of the bedside nurse at the ward round review. The ward round checklist reduced omissions. Communication with patients during ward rounds was an area which needed to be improved. The introduction of a new ward round approach and audit of its practice has enabled an improvement in the quality of patient care by: Giving more opportunity for the nurse to participate and feel part of the ward round. Reduction of omissions through the use of a ward round checklist. Improved clarity among the MDT by the use of bedside nurse verbal summarizing of the plan of care. Nurses' full participation in ward rounds is essential to ensure effective communication and enhance patient safety. © 2015 British Association of Critical Care Nurses.

Introduction Our goal was to determine if heated gel for emergency department (ED) bedside ultrasonography improves patient satisfaction compared to room-temperature gel. Methods We randomized a convenience sample of ED patients determined by their treating physician to require a bedside ultrasound (US) study to either heated gel (102.0° F) or room-temperature gel (82.3° F). Investigators performed all US examinations. We informed all subjects that the study entailed investigation into various measures to improve patient satisfaction with ED US examinations but did not inform them of our specific focus on gel temperature. Investigators wore heat-resistant gloves while performing the examinations to blind themselves to the gel temperature. After completion of the US, subjects completed a survey including the primary outcome measure of patient satisfaction as measured on a 100-mm visual analogue scale (VAS). A secondary outcome was patient perceptions of sonographer professionalism measured by an ordinal scale (1–5). Results We enrolled 124 subjects; 120 completed all outcome measures. Of these, 59 underwent randomization to US studies with room-temperature gel and 61 underwent randomization to heated US gel. Patient 100-mm VAS satisfaction scores were 83.9 among patients undergoing studies with room-temperature gel versus 87.6 among subjects undergoing studies with heated gel (effect size 3.7, 95% confidence interval −1.3–8.6). There were similarly no differences between the two arms with regard to patient perceptions of sonographer professionalism. Conclusion The use of heated ultrasound gel appears to have no material impact on the satisfaction of ED patients undergoing bedside ultrasound studies. PMID:29085538

Objective: Bedside lung ultrasound (LUS) is a noninvasive, readily available imaging modality that can complement clinical evaluation. The Bedside Lung Ultrasound in Emergency (BLUE) protocol has demonstrated a high diagnostic accuracy in patients with acute respiratory failure (ARF). Recently, bedside LUS has been added to the medical training program of our ICU. The aim of this study was to investigate the accuracy of LUS based on the BLUE protocol, when performed by physicians who are not ultrasound experts, to guide the diagnosis of ARF. Methods: Over a one-year period, all spontaneously breathing adult patients consecutively admitted to the ICU for ARF were prospectively included. After training, 4 non-ultrasound experts performed LUS within 20 minutes of patient admission. They were blinded to patient medical history. LUS diagnosis was compared with the final clinical diagnosis made by the ICU team before patients were discharged from the ICU (gold standard). Results: Thirty-seven patients were included in the analysis (mean age, 73.2 ± 14.7 years; APACHE II, 19.2 ± 7.3). LUS diagnosis had a good agreement with the final diagnosis in 84% of patients (overall kappa, 0.81). The most common etiologies for ARF were pneumonia (n = 17) and hemodynamic lung edema (n = 15). The sensitivity and specificity of LUS as measured against the final diagnosis were, respectively, 88% and 90% for pneumonia and 86% and 87% for hemodynamic lung edema. Conclusions: LUS based on the BLUE protocol was reproducible by physicians who are not ultrasound experts and accurate for the diagnosis of pneumonia and hemodynamic lung edema. PMID:25750675

Implementation of fluorescence confocal mosaicking microscopy by “early adopter” Mohs surgeons and dermatologists: recent progress

Abstract. Confocal mosaicking microscopy (CMM) enables rapid imaging of large areas of fresh tissue ex vivo without the processing that is necessary for conventional histology. When performed in fluorescence mode using acridine orange (nuclear specific dye), it enhances nuclei-to-dermis contrast that enables detection of all types of basal cell carcinomas (BCCs), including micronodular and thin strands of infiltrative types. So far, this technique has been mostly validated in research settings for the detection of residual BCC tumor margins with high sensitivity of 89% to 96% and specificity of 99% to 89%. Recently, CMM has advanced to implementation and testing in clinical settings by “early adopter” Mohs surgeons, as an adjunct to frozen section during Mohs surgery. We summarize the development of CMM guided imaging of ex vivo skin tissues from bench to bedside. We also present its current state of application in routine clinical workflow not only for the assessment of residual BCC margins in the Mohs surgical setting but also for some melanocytic lesions and other skin conditions in clinical dermatology settings. Last, we also discuss the potential limitations of this technology as well as future developments. As this technology advances further, it may serve as an adjunct to standard histology and enable rapid surgical pathology of skin cancers at the bedside. PMID:28199474

Translational physiology: from molecules to public health.

2013-07-15

The term 'translational research' was coined 20 years ago and has become a guiding influence in biomedical research. It refers to a process by which the findings of basic research are extended to the clinical research setting (bench to bedside) and then to clinical practice and eventually health policy (bedside to community). It is a dynamic, multidisciplinary research approach. The concept of translational physiology applies the translational research model to the physiological sciences. It differs from the traditional areas of integrative and clinical physiology by its broad investigative scope of basic research to community health. Translational physiology offers exciting opportunities, but presently is under-developed and -utilized. A key challenge will be to expand physiological research by extending investigations to communities of patients and healthy (or at risk) individuals. This will allow bidirectional physiological investigation throughout the translational continuum: basic research observations can be studied up to the population level, and mechanisms can be assessed by 'reverse translation' in clinical research settings and preclinical models based on initial observations made in populations. Examples of translational physiology questions, experimental approaches, roadblocks and strategies for promotion are discussed. Translational physiology provides a novel framework for physiology programs and an investigational platform for physiologists to study function from molecular events to public health. It holds promise for enhancing the completeness and societal impact of our work, while further solidifying the critical role of physiology in the biomedical research enterprise.

New products evolving from research and development can only be translated to medical practice on a large scale if they are reimbursed by third-party payers. Yet the decision processes regarding reimbursement are highly complex and internationally heterogeneous. This study develops a process-oriented framework for monitoring these so-called fourth hurdle procedures in the context of product development from bench to bedside. The framework is suitable both for new drugs and other medical technologies. The study is based on expert interviews and literature searches, as well as an analysis of 47 websites of coverage decision-makers in England, Germany and the USA. Eight key steps for monitoring fourth hurdle procedures from a company perspective were determined: entering the scope of a healthcare payer; trigger of decision process; assessment; appraisal; setting level of reimbursement; establishing rules for service provision; formal and informal participation; and publication of the decision and supplementary information. Details are given for the English National Institute for Health and Clinical Excellence, the German Federal Joint Committee, Medicare's National and Local Coverage Determinations, and for Blue Cross Blue Shield companies. Coverage determination decisions for new procedures tend to be less formalized than for novel drugs. The analysis of coverage procedures and requirements shows that the proof of patient benefit is essential. Cost-effectiveness is likely to gain importance in future.

To assess the usefulness of the new NEMA (Neck Circumference Minus Acromion-Acromion Distance) parameter, in preoperative identification of patients' difficult intubation and compare it with other commonly used scales and tests. Prospective study. District Specialist Hospital of Lublin, Poland. Six hundreds twenty-nine patients underwent nonemergency surgical interventions. The NEMA parameter was confronted with: Modified Mallampati classification, TMD, RHTMD, NC, MPND, SMD, I-I D, A-AD, and medical history of difficult intubation and diagnosed obstructive sleep apnea syndrome or snoring. Higher medians of NEMA and Mallampati parameters were reported in patients with difficult intubation. AUC for Mallampati parameter was 0.733 while the NEMA parameter's AUC was 0.625. Sensitivity and specificity for Mallampati and NEMA parameter were respectively 0.79; 0.55 and 0.42; 0.75. Significantly higher MPN, RHTMD, Mallampati, and NEMA parameter were observed in patients in whom the BURP was used. Easy intubation occurs more frequently in patients with a history of OSAS or snoring than in those with difficult intubation. It seems that none of the known bedside tests for predicting difficult intubation have a discriminating power sufficient for clinicians. Our study draws attention to a novel parameter, called NEMA, which appears to be a strong predictor of DEI, especially in combination with the Mallampati scale. Copyright © 2016 Elsevier Inc.

2015-02-01

Global mental health has emerged as an important specialty. It has drawn attention to the burden of mental illness and to the relative gap in mental health research and services around the world. Global mental health has raised the question of whether this gap is a developmental issue, a health issue, a human rights issue, or a combination of these issues-and it has raised awareness of the need to develop new approaches for building capacity, mobilising resources, and closing the research and treatment gap. Translational neuroscience has also advanced. It comprises an important conceptual approach to understanding the neurocircuitry and molecular basis of mental disorders, to rethinking how best to undertake research on the aetiology, assessment, and treatment of these disorders, with the ultimate aim to develop entirely new approaches to prevention and intervention. Some apparent contrasts exist between these fields; global mental health emphasises knowledge translation, moving away from the bedside to a focus on health systems, whereas translational neuroscience emphasises molecular neuroscience, focusing on transitions between the bench and bedside. Meanwhile, important opportunities exist for synergy between the two paradigms, to ensure that present opportunities in mental health research and services are maximised. Here, we review the approaches of global mental health and clinical neuroscience to diagnosis, pathogenesis, and intervention, and make recommendations for facilitating an integration of these two perspectives.

SU-F-T-653: Radiation Exposure from Cs-131 Permanent Seed Implants

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

Giaddui, T; Hardin, M; To, D

Purpose: Permanent seed implants have traditionally been used to treat prostate, lung and head or neck cancers using I-125 and Pd-103. Cs-131, which has higher dose rate is being used to treat brain, head and/or neck cancers in our clinic, therefore, we chose to monitor the dose received by surgeons during the extensive procedure. The aims of this work are to assess the level of radiation exposure to surgeons and the instantaneous exposure at bedside and 1 m from patients. Methods: Ten patients received Cs-131 implants for recurrent brain,head and/or neck cancer; the median implanted activity, number of implanted seedsmore » and prescription dose at 0.5 cm from the perpendicular plane of the implant were: 54.3 mCi (14.52 – 77); 19 (4 – 24) and 60 Gy (range 42 – 60) respectively. Radiation exposure was recorded at bedside and 1 m from the patient using Victoreen ion chamber (Fluke Biomedical, Cleveland, OH). Exposure to surgeons was measured using TLD (Mirion Technologies (GDS), Inc., USA). Results: The median equivalent dose rate at 1 m and bedside immediately following implantation were 1.49×10-2 mSv/h (8.77×10-3–2.63×10-2) and 7.76×10-2 mSv/h (3.1×10-2– 1.53×10-1) respectively. Median equivalent dose to surgeons’ hands was 0.60 mSv (0.33 – 1.48) and no doses were detected for whole-body. Surgical reconstruction for one patient was performed 71 days post-implant and resulted in zero exposure to surgeons. Conclusion: The recorded exposure rates were low when compared with the literature. Post procedure surveys at bed site and 1 m indicated that all patients were within safe limits for discharge (< 0.05 mSv/h at 1 m). However, as a precautionary measure, patients were advised to avoid direct contact with children and pregnant women within four weeks of the implant and stay at least at 3 ft from other people. Surgeons doses were well within occupational dose limits.« less

Augmented reality (AR) systems are currently being explored by a broad spectrum of industries, mainly for improving point-of-care access to data and images. Especially in surgery and especially for timely decisions in emergency cases, a fast and comprehensive access to images at the patient bedside is mandatory. Currently, imaging data are accessed at a distance from the patient both in time and space, i.e., at a specific workstation. Mobile technology and 3-dimensional (3D) visualization of radiological imaging data promise to overcome these restrictions by making bedside AR feasible. In this project, AR was realized in a surgical setting by fusing a 3D-representation of structures of interest with live camera images on a tablet computer using marker-based registration. The intent of this study was to focus on a thorough evaluation of AR. Feasibility, robustness, and accuracy were thus evaluated consecutively in a phantom model and a porcine model. Additionally feasibility was evaluated in one male volunteer. In the phantom model (n = 10), AR visualization was feasible in 84% of the visualization space with high accuracy (mean reprojection error ± standard deviation (SD): 2.8 ± 2.7 mm; 95th percentile = 6.7 mm). In a porcine model (n = 5), AR visualization was feasible in 79% with high accuracy (mean reprojection error ± SD: 3.5 ± 3.0 mm; 95th percentile = 9.5 mm). Furthermore, AR was successfully used and proved feasible within a male volunteer. Mobile, real-time, and point-of-care AR for clinical purposes proved feasible, robust, and accurate in the phantom, animal, and single-trial human model shown in this study. Consequently, AR following similar implementation proved robust and accurate enough to be evaluated in clinical trials assessing accuracy, robustness in clinical reality, as well as integration into the clinical workflow. If these further studies prove successful, AR might revolutionize data access at patient bedside.

Blood product transfusion is one of the most common invasive procedures performed in the health care setting. In contrast to pharmaceuticals, blood is actually a liquid transplant. Transfusion complications consequently encompass complex biological processes and infectious possibilities. Changes in vital signs are regularly seen during transfusion. Knowledge of common transfusion reaction signs and symptoms enables the clinical team to differentiate a normal patient response from a life-threatening reaction. Direct care nurses responsible for this procedure play a vital role in its success. Understanding the possible complications of transfusion and how to quickly recognize reactions at the bedside helps ensure the best patient outcomes.

Bench-to-bedside review: Rapid molecular diagnostics for bloodstream infection - a new frontier?

PubMed Central

2012-01-01

Among critically ill patients, the diagnosis of bloodstream infection poses a major challenge. Current standard bacterial identification based on blood culture platforms is intrinsically time-consuming and slow. The continuous evolvement of molecular techniques has the potential of providing a faster, more sensitive and direct identification of causative pathogens without prior need for cultivation. This may ultimately impact clinical decision-making and antimicrobial treatment. This review summarises the currently available technologies, their strengths and limitations and the obstacles that have to be overcome in order to develop a satisfactory bedside point-of-care diagnostic tool for detection of bloodstream infection.

There are a multitude of diagnostic clues contained in clothing, jewelry, possessions and other extracorporeal attachments that each patient brings with him or her to a physician. Because of the emphasis of classic physical diagnosis on the body of a patient solely, and because of modern practices that may have patients stripped of these articles before the first encounter with their physician, these interesting and enlightening findings are often ignored or unavailable. Incorporation of these observations into the panoply of data obtained from the history and physical examination will enhance both the accuracy and adventure of differential diagnosis. Such exercises in observation, moreover, may increase general physical diagnostic skills as well as enliven bedside rounds.

Acute graft-versus-host disease: from the bench to the bedside

During the past decade, progress in basic immunology has been impressive. In parallel, whereas our understanding of the pathophysiology of acute graft-versus-host disease (GVHD) has greatly improved, so has our knowledge of the complexities of the immune system. Much of the immunobiology of acute GVHD has been gleaned from preclinical models and far less from correlations with clinical observations or therapeutic interventions. In this review, we summarize some of the major advances in GVHD pathophysiology, including the translation of these from the bench to the bedside, and discuss preclinical approaches that warrant further exploration in the clinic.

The objective of this study was to demonstrate the feasibility of a bar code-based identification system for the pre-transfusion check at the bedside in the setting of pre-operative autologous blood donation (PABD). Between July 2003 and December 2008 we determined the compliance rate and causes of failure of electronic bedside checking for PABD transfusion. A total of 5627 (9% of all transfusions) PABD units were administered without a single mistransfusion. The overall rate of compliance with electronic checking was 99%. The bar code-based identification system was applicable to the pre-transfusion check for PABD transfusion. Copyright © 2010 Elsevier Ltd. All rights reserved.

To determine the prevalence of retinopathy among patients undergoing heart transplantation screening and to determine the impact of this finding on eligibility for transplantation. A retrospective case series was collected to perform an institutional review of all inpatient consults for dilated eye examinations on potential heart transplant candidates over 5.5 years-from March 27, 2008 to October 10, 2014. Measured outcomes included the presence or absence of retinopathy and the effect of retinopathy, if present, on a patient's eligibility for cardiac transplantation. A total of 155 heart transplant candidates underwent bedside ophthalmologic examination as part of their heart transplant candidacy workup. Retinopathy was found in 16 (10%) of these patients: diabetic retinopathy in 13 (8.4%) and hypertensive retinopathy in 3 (1.9%). None of these patients were excluded from the transplant candidacy based on the presence of retinopathy. On bedside ophthalmologic examination, retinopathy is an uncommon finding among cardiac transplant candidates. Retinopathy did not preclude transplantation in these patients. We question the utility of the present system of bedside ophthalmic consultation of heart transplant candidates. This may not be an optimal allocation of provider resources. Further studies are warranted to determine an appropriate protocol for ocular evaluation of these patients.

Implantable cardioverter defibrillators have been shown to reduce all-cause mortality in some patient populations at risk of sudden death. New Canadian guidelines recommend implantable cardioverter defibrillator therapy for these patients. However, the need for these devices exceeds the funded volumes in many Canadian jurisdictions. As a result, rationing of this resource has been necessary. While rationing at the macro (Ministry of Health) and meso (hospital) levels has achieved some level of acceptance by society, the responsibility for the decisions taken at the micro (individual) patient level actually rests with the physician at the bedside. This 'bedside rationing' creates a moral dilemma for physicians, who are torn between their traditional fiduciary role as 'patient advocate' and the competing role of 'gatekeeper'. This 'downward delegation' of rationing decision-making obscures the reality that rationing occurs, and encourages covert, opaque and inconsistent approaches. The remedy is the development of fair, legitimate procedures for making rationing decisions that include guidelines that structure and constrain those decisions. Macro- and meso-level stakeholders must also recognize and take responsibility for their part in restricting resources in a broadly inclusive and transparent process.

Although enteral feeding in critically ill patients has been shown to be beneficial, reliable postpyloric placement of feeding tubes remains a challenge. The standard of care involves blind placement, frequently requiring multiple attempts, and radiographs. To evaluate the effect of electromagnetic-guided bedside placement in reducing time to establishment of feeding, lung placement, use of radiography, and cost, we initiated a prospective trial using electromagnetic-guided bedside placement and compared them to a retrospective cohort. Fifty-three consecutive placements of nasoenteral feeding tubes were made using electromagnetic-guidance on patients requiring enteral nutrition in a surgical intensive care unit at a tertiary care center. Sixty-three placement attempts in the preceding seven months served as controls. There were no significant differences between the two groups in terms of age, sex, weight, body mass index, hiatal or ventral hernias, or previous esophageal/gastric operations. The number of radiographs needed per patient, need for fluoroscopy, radiology charge per patient for the tube placement, and time from first attempt at placement to confirmation of postpyloric location were lower for the electromagnetic-guided group. Use of electromagnetic guidance allows reliable and cost-effective postpyloric enteral feeding tube placement compared with blind insertion.

Right lower quadrant pain in young females presents a frequent diagnostic challenge for emergency physicians, with a broad differential and several important diagnoses. Using an "ultrasound first" imaging strategy can help decrease the use of computed tomography scans, with associated savings in radiation exposure, cost, and other resource use. We report a case of right lower quadrant pain in a young woman. After her initial history and physical examination, appendicitis was the leading differential. A bedside ultrasound was performed, leading to the uncommon diagnosis of rectus abdominis muscle tear. The sonographic findings of a muscle tear include increase in size, loss of linear, homogeneous architecture, and decreased echogenicity. Making this diagnosis at the bedside using ultrasound obviated the need for further imaging, avoiding unnecessary radiation exposure, and decreasing emergency department length of stay and overall cost, while leading to a tailored treatment plan. Why Should an Emergency Physician Be Aware of This? Rectus abdominis tear is a cause of right lower quadrant pain that may mimic appendicitis and should be considered in patients with this complaint. The ability to make this diagnosis with bedside ultrasound may assist in several important patient-oriented outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

The Staff Nurse Clinical Leader at the Bedside: Swedish Registered Nurses' Perceptions.

PubMed

Larsson, Inga E; Sahlsten, Monika J M

2016-01-01

Registered nurses at the bedside are accountable for and oversee completion of patient care as well as directly leading and managing the provision of safe patient care. These nurses have an informal leadership role that is not associated with any given position. Leadership is a complex and multifaceted concept and its meaning is unclear, especially in the staff nurse context. The aim was to describe registered nurses' perceptions of what it entails to be the leader at the bedside in inpatient physical care. A phenomenographic approach was employed. Interviews were performed with Swedish registered nurses ( n = 15). Five descriptive categories were identified: demonstrating clinical knowledge, establishing a good atmosphere of collaboration, consciously structuring the work in order to ensure patients' best possible nursing care, customized presence in the practical work with patients according to predetermined prerequisites, and monitoring coworkers' professional practice. Registered nurses informal role as leader necessitates a social process of deliberate effort to attain and maintain leader status and authority. Participants used deliberate communicative approaches and interactive procedures. Leader principles grounded in the core values of the nursing profession that ensure nursing values and person-centered attributes were a key aspect.

Standard care for infants on extracorporeal life support (ECLS) relies on intermittent measurement of blood glucose (BG); however, this can lead to significant changes in BG that go unrecognized for several hours. The present study was designed to assess performance and clinical applicability of a subcutaneous glucose sensor technology modified for use as a blood-contacting sensor within the ECLS circuit. Twelve children, aged 3 years or less, requiring ECLS support were studied. Three continuous glucose sensors (Medtronic MiniMed) were inserted into hubs placed in line with the ECLS circuit. Blood glucose was assessed with a laboratory analyzer (BG(LAB); Bayer Rapidlab 860) approximately every 5 h (mean 4.9 ± 3.3 h) with more frequent samples obtained with a bedside monitor (HemoCue) as needed. Sensor current (I(SIG)) was transmitted to a laptop computer and retrospectively calibrated using BGLAB. Sensor performance was assessed by mean absolute relative difference (MARD), linear regression slope and intercept, and correlation, all with BGLAB as reference. The BGLAB averaged 107.6 ± 36.4 mg/dl (mean ± standard deviation) ranging from 58 to 366 mg/dl. The MARD was 11.4%, with linear regression slope (0.86 ± 0.030) and intercept (9.0 ± 3.2 mg/dl) different from 1 and 0, respectively (p < .05), and correlation (r² = 0.76; p < .001). The system was not associated with any adverse events, and placement and removal into the hubs was easily accomplished. Instances in which more frequent BG values were obtained using a bedside HemoCue (BGHEMO) monitor showed the sensor to respond rapidly to changes. We conclude that continuous sensors can be adapted for use in an ECLS circuit with accuracy similar to or better than that achieved with the subcutaneous site. Continuous glucose monitoring in this population can rapidly detect changes in BG that would not otherwise be observed. Further studies will be needed to assess the benefit of continuous glucose monitoring in this population. © 2010 Diabetes Technology Society.

Assessment and Management of Volume Overload and Congestion in Chronic Heart Failure: Can Measuring Blood Volume Provide New Insights?

PubMed

Miller, Wayne L

2017-01-01

Volume overload and fluid congestion remain primary clinical challenges in the assessment and management of patients with chronic heart failure (HF). The pathophysiology of volume regulation is complex, and the simple concept of passive intravascular fluid accumulation is not adequate. The dynamics of interstitial and intravascular fluid compartment interactions and fluid redistribution from venous splanchnic beds to the central pulmonary circulation need to be taken into account in strategies of volume management. Clinical bedside evaluations and right heart hemodynamic assessments can alert of changes in volume status, but only the quantitative measurement of total blood volume can help identify the heterogeneity in plasma volume and red blood cell mass that are features of volume overload in chronic HF. The quantitative assessment of intravascular volume is an effective tool to help guide individualized, appropriate therapy. Not all volume overload is the same, and the measurement of intravascular volume identifies heterogeneity to guide tailored therapy.

Does point-of-care functional echocardiography enhance cardiovascular care in the NICU?

PubMed

Sehgal, A; McNamara, P J

2008-11-01

Although the last two decades have seen major advances in the care of sick, extremely premature newborns, the approach to cardiovascular assessment and monitoring remains suboptimal owing to an overreliance on poorly predictive clinical markers such as heart rate or capillary refill time. Point-of-care functional echocardiography (PCFecho) enables real-time evaluation of cardiac performance and systemic hemodynamics to characterize acute physiology, identify the exact nature of cardiovascular compromise and guide therapeutic decisions. In this article, we will review four clinical scenarios where bedside functional cardiac imaging enabled delineation of the real clinical problem and refinement of the therapeutic care plan with direct patient benefits.

Cardiac examination is an essential aspect of the physical examination. Previous studies have shown poor diagnostic accuracy, but most used audio recordings, precluding correlation with visible observations. The training spectrum from medical students (MSs) to faculty has not been tested, to our knowledge. A validated 50-question, computer-based test was used to assess 4 aspects of cardiac examination competency: (1) cardiac physiology knowledge, (2) auditory skills, (3) visual skills, and (4) integration of auditory and visual skills using computer graphic animations and virtual patient examinations (actual patients filmed at the bedside). We tested 860 participants: 318 MSs, 289 residents (225 internal medicine and 64 family medicine), 85 cardiology fellows, 131 physicians (50 full-time faculty, 12 volunteer clinical faculty, and 69 private practitioners), and 37 others. Mean scores improved from MS1-2 to MS3-4 (P = .003) but did not improve or differ significantly among MS3, MS4, internal medicine residents, family medicine residents, full-time faculty, volunteer clinical faculty, and private practitioners. Only cardiology fellows tested significantly better (P<.001), and they were the best in all 4 subcategories of competency, whereas MS1-2 were the worst in the auditory and visual subcategories. Participants demonstrated low specificity for systolic murmurs (0.35) and low sensitivity for diastolic murmurs (0.49). Cardiac examination skills do not improve after MS3 and may decline after years in practice, which has important implications for medical decision making, patient safety, cost-effective care, and continuing medical education. Improvement in cardiac examination competency will require training in simultaneous audio and visual examination in faculty and trainees.

Simulation-guided cardiac auscultation improves medical students' clinical skills: the Pavia pilot experience.

Clinical evaluation is the cornerstone of any cardiac diagnosis, although excessive over-specialisation often leads students to disregard the value of clinical skills, and to overemphasize the approach to instrumental cardiac diagnosis. Time restraints, low availability of "typical" cardiac patients on whom to perform effective bedside teaching, patients' respect and the underscoring of the value of clinical skills all lead to a progressive decay in teaching. Simulation-guided cardiac auscultation may improve clinical training in medical students and residents. Harvey(©) is a mannequin encompassing more than 50 cardiac diagnoses that was designed and developed at the University of Miami (Florida, USA). One of the advantages of Harvey(©) simulation resides in the possibility of listening, comparing and discussing "real" murmurs. To objectively assess its teaching performance, the capability to identify five different cardiac diagnoses (atrial septal defect, normal young subject, mitral stenosis with tricuspid regurgitation, chronic mitral regurgitation, and pericarditis) out of more than 50 diagnostic possibilities was assessed in 523 III-year medical students (i.e. at the very beginning of their clinical experience), in 92 VI-year students, and in 42 residents before and after a formal 10-h teaching session with Harvey(©). None of them had previously experienced simulation-based cardiac auscultation in addition to formal lecturing (all three groups) and bedside teaching (VI-year students and residents). In order to assess the "persistence" of the acquired knowledge over time, the test was repeated after 3 years in 85 students, who did not repeat the formal 10-h teaching session with Harvey(©) after the III year. As expected, the overall response was poor in the "beginners" who correctly identified 11.0 % of the administered cardiac murmurs. After simulation-guided training, the ability to recognise the correct cardiac diagnoses was much better (72.0 %; p < 0.001 vs. baseline). Rather unexpectedly, before the tutorial, the performance of VI-year students and of residents was not significantly different from their III-year colleagues, since the two groups correctly identified 14.2 and 16.2 % of the diagnoses, respectively. After the tutorial, the VI-year students and the residents also improved their overall performance (to 73.1 and 76.1 %, respectively; p < 0.001 for both when compared to before the tutorial). The persistence of this capability after 3 years was remarkable, since the 85 students who repeated the test without any further exposure to the 10-h teaching session with Harvey(©) correctly identified 68.4 % of the possible cardiac diagnoses (p < 0.001 vs. baseline). These data underscore the importance of clinical training in order to improve auscultation skills in our academic setting, prompting to redesign teaching curricula. Simulation-based cardiac auscultation should be considered as the "missing link" between formal lecturing and bedside teaching of heart sounds and murmurs.

Bench-to-bedside review: Inhaled nitric oxide therapy in adults

Creagh-Brown, Benedict C; Griffiths, Mark JD; Evans, Timothy W

2009-01-01

Nitric oxide (NO) is an endogenous mediator of vascular tone and host defence. Inhaled nitric oxide (iNO) results in preferential pulmonary vasodilatation and lowers pulmonary vascular resistance. The route of administration delivers NO selectively to ventilated lung units so that its effect augments that of hypoxic pulmonary vasoconstriction and improves oxygenation. This 'Bench-to-bedside' review focuses on the mechanisms of action of iNO and its clinical applications, with emphasis on acute lung injury and the acute respiratory distress syndrome. Developments in our understanding of the cellular and molecular actions of NO may help to explain the hitherto disappointing results of randomised controlled trials of iNO. PMID:19519946

There are a multitude of diagnostic clues contained in clothing, jewelry, possessions and other extracorporeal attachments that each patient brings with him or her to a physician. Because of the emphasis of classic physical diagnosis on the body of a patient solely, and because of modern practices that may have patients stripped of these articles before the first encounter with their physician, these interesting and enlightening findings are often ignored or unavailable. Incorporation of these observations into the panoply of data obtained from the history and physical examination will enhance both the accuracy and adventure of differential diagnosis. Such exercises in observation, moreover, may increase general physical diagnostic skills as well as enliven bedside rounds. PMID:7135953

The purpose of this study was to measure RNs' perceptions of teamwork skills and behaviors in their work environment during a multiphase multisite nursing organizational teamwork development initiative. Teamwork is essential for patient safety in healthcare organizations and nursing teams. Organizational development supporting effective teamwork should include a just culture, engaged leadership, and teamwork training. A cross-sectional survey study of bedside RNs was conducted in one 5-hospital healthcare system after a TeamSTEPPS teamwork training initiative. TeamSTEPPS teamwork training related to improved RN perceptions of leadership. Initiatives to align the perspectives and teamwork efforts of leaders and bedside nurses are indicated and should involve charge nurses in the design.

Supporting caregivers' workflow with mobile applications (apps) is a growing trend. At the bedside, apps can provide new ways to support the documentation process rather than using a desktop computer in a nursing office. Although these applications show potential, few existing reports have studied the real impact of such solutions. At the University Hospitals of Geneva, we developed BEDside Mobility, a mobile application supporting nurses' daily workflow. In a pilot study, the app was trialed in two wards for a period of one month. We collected data of the actual usage of the app and asked the users to complete a tailored technology acceptance model questionnaire at the end of the study period. Results show that participation remain stable with time with participants using in average the tool for almost 29 minutes per day. The technology acceptance questionnaires revealed a high usability of the app and good promotion from the institution although users did not perceive any increase in productivity. Overall, intent of use was divergent between promoters and antagonist. Furthermore, some participants considered the tool as an addition to their workload. This evaluation underlines the importance of helping all end users perceive the benefits of a new intervention since coworkers strong influence each other.

High costs and a paucity of available operating time have led us to seek alternatives to operatively placed vascular access systems. This prospective study is the initial report of a peripheral port system (P.A.S. PORT System, Pharmacia Deltec, Inc.) placed at the bedside. Seventy-nine patients (52 male, 27 female), ages 3-92 years, had ports implanted by surgical residents with attending supervision. Sixty-eight (86%) received the P.A.S. PORT for long-term antibiotics, antifungal, or antiviral therapy; four (5%) for TPN infusion; three (4%) for blood products; two (3%) for chemotherapy; and two (3%) for iv narcotics. Ports were placed in 10 (13%) HIV(+) patients, three (4%) who were fully anticoagulated, and one who was a hemophiliac with a platelet count of zero. Eight patients (10%) developed superficial phlebitis, all of which resolved with nonsteroidal anti-inflammatory agents within 48 hr without port removal. Seven patients (9%) had their port removed due to infection. The average hospital charge to place the P.A.S. PORT System was $1488.00 vs $2811.00 for a tunneled external chest catheter and $3729.00 for the placement of a chest port. Bedside insertion of vascular access devices can be safely performed with acceptable infection rates allowing more efficient use of hospital operating rooms and with substantial cost savings.

Iterative integral parameter identification of a respiratory mechanics model.

Patient-specific respiratory mechanics models can support the evaluation of optimal lung protective ventilator settings during ventilation therapy. Clinical application requires that the individual's model parameter values must be identified with information available at the bedside. Multiple linear regression or gradient-based parameter identification methods are highly sensitive to noise and initial parameter estimates. Thus, they are difficult to apply at the bedside to support therapeutic decisions. An iterative integral parameter identification method is applied to a second order respiratory mechanics model. The method is compared to the commonly used regression methods and error-mapping approaches using simulated and clinical data. The clinical potential of the method was evaluated on data from 13 Acute Respiratory Distress Syndrome (ARDS) patients. The iterative integral method converged to error minima 350 times faster than the Simplex Search Method using simulation data sets and 50 times faster using clinical data sets. Established regression methods reported erroneous results due to sensitivity to noise. In contrast, the iterative integral method was effective independent of initial parameter estimations, and converged successfully in each case tested. These investigations reveal that the iterative integral method is beneficial with respect to computing time, operator independence and robustness, and thus applicable at the bedside for this clinical application.

This is a prospective study to find out whether an interactive large-group case-based teaching approach combined with small-group bedside teaching improves student satisfaction and learning outcome in a practical dermatology course. During two consecutive terms a rotating system of large-group interactive case-study-method teaching with two tutors (one content expert, one process facilitator) and bedside teaching with randomly appointed tutors was evaluated with a nine-item questionnaire and multiple-choice test performed at the beginning and the end of the course (n = 204/231 students evaluable). The results of three different didactic approaches utilized over the prior year served as a control. The interactive course was rated significantly better (p < 0.0001) than the standard course with regard to all items. The aggregate mark given by the students for the whole course was 1.58-0.61 (mean +/- SD, range 1 (good)-5 (poor)). This was significantly better than the standard course (p < 0.0001) and not different from small-group teaching approaches. The mean test results in the final examination improved significantly (p < 0.01). The combination of large-group interactive teaching and small-group bedside teaching was well accepted, improved the learning outcome, was rated as good as a small-group didactic approach and needed fewer resources in terms of personnel.

Abstract To evaluate the effect of a novel procedure using real-time ultrasonography to assist nasojejunal tube placement at bedside in patients with severe acute pancreatitis (SAP). Single center, prospective descriptive study in a 15-bed surgery intensive care unit of a university hospital. Thirty SAP patients were enrolled. The whole procedure of placing nasojejunal tube was performed by a single physician, who places nasojejunal tube at the bedside and performs ultrasonography to guide the tube positioning. The final nasojejunal tube position was confirmed by abdominal radiograph. The successful rate of the procedure as well as the time it took, the time from the decision of enteral feeding to commencement of feeding, and complications were recorded. Thirty-six intubations were performed in 30 patients by using ultrasonography-assisted method at bedside. Nasojejunal tubes were successful placed in 28 of 30 patients (93.3%). The average time of successful placement was 22.07 ± 5.78 minutes. The median time between physician's decision for tube placement and feeding initiation was 5.5 (2, 24) hours. No adverse events occurred in all of patients. This novel method of nasojejunal tube placement under ultrasound guidance is practical, less time consuming and reliable. PMID:29137035

A nasogastric tube (NGT) insertion is a common procedure in intensive care units, with some serious complications that result from the malposition of the NGT tip. This pilot study was designed to investigate the efficiency of ultrasound in verifying correct NGT placement and to compare these results with radiographic findings. This was a single-center, double-blind prospective study of patients who had received an NGT in the pediatric critical care unit. Twenty-one patients aged 1 month to 18 years were included in this study. All NGTs were inserted by the same critical care physician. After insertion, the physician first confirmed NGT placement by the auscultation of the epigastrium following the insufflation of air. Confirmation was supplemented with an abdominal radiograph. A radiologist who was unaware of the radiographic findings performed bedside sonography on all patients and verified the location of the NGTs. The findings from these 2 physicians were then compared. NGTs were inserted without any complications, and none of the NGTs were positioned in the respiratory tract in any of the patients. All NGT tips were visualized by radiography and sonography with a sensitivity of 100%. Bedside sonography performed by a radiologist is an effective and sensitive diagnostic procedure for confirming the correct NGT position in patients in the pediatric critical care unit.

Translational Epidemiology in Psychiatry

Translational research generally refers to the application of knowledge generated by advances in basic sciences research translated into new approaches for diagnosis, prevention, and treatment of disease. This direction is called bench-to-bedside. Psychiatry has similarly emphasized the basic sciences as the starting point of translational research. This article introduces the term translational epidemiology for psychiatry research as a bidirectional concept in which the knowledge generated from the bedside or the population can also be translated to the benches of laboratory science. Epidemiologic studies are primarily observational but can generate representative samples, novel designs, and hypotheses that can be translated into more tractable experimental approaches in the clinical and basic sciences. This bedside-to-bench concept has not been explicated in psychiatry, although there are an increasing number of examples in the research literature. This article describes selected epidemiologic designs, providing examples and opportunities for translational research from community surveys and prospective, birth cohort, and family-based designs. Rapid developments in informatics, emphases on large sample collection for genetic and biomarker studies, and interest in personalized medicine—which requires information on relative and absolute risk factors—make this topic timely. The approach described has implications for providing fresh metaphors to communicate complex issues in interdisciplinary collaborations and for training in epidemiology and other sciences in psychiatry.

Kashyap, Vipul

The success of new innovations and technologies are very often disruptive in nature. At the same time, they enable novel next generation infrastructures and solutions. These solutions introduce great efficiencies in the form of efficient processes and the ability to create, organize, share and manage knowledge effectively; and the same time provide crucial enablers for proposing and realizing new visions. In this paper, we propose a new vision of the next generation healthcare enterprise and discuss how Translational Medicine, which aims to improve communication between the basic and clinical sciences, is a key requirement for achieving this vision. This will lead therapeutic insights may be derived from new scientific ideas - and vice versa. Translation research goes from bench to bedside, where theories emerging from preclinical experimentation are tested on disease-affected human subjects, and from bedside to bench, where information obtained from preliminary human experimentation can be used to refine our understanding of the biological principles underpinning the heterogeneity of human disease and polymorphism(s). Informatics and semantic technologies in particular, has a big role to play in making this a reality. We identify critical requirements, viz., data integration, clinical decision support and knowledge maintenance and provenance; and illustrate semantics-based solutions wrt example scenarios and use cases.

The Utility of Teleultrasound to Guide Acute Patient Management.

PubMed

Becker, Christian; Fusaro, Mario; Patel, Dhruv; Shalom, Isaac; Frishman, William H; Scurlock, Corey

Ultrasound has evolved into a core bedside tool for diagnostic and management purposes for all subsets of adult and pediatric critically-ill patients. Teleintensive care unit coverage has undergone a similar rapid expansion period throughout the United States. Round-the-clock access to ultrasound equipment is very common in today's intensive care unit, but 24/7 coverage with staff trained to acquire and interpret point-of-care ultrasound in real time is lagging behind equipment availability. Medical trainees and physician extenders require attending level supervision to ensure consistent image acquisition and accurate interpretation. Teleintensivists can extend the utility of ultrasound by supervising and guiding providers without or with only partial training in ultrasound, and also by extending direct trainee ultrasound supervision to time periods when no direct bedside attending supervisor is available, and when treatment decisions otherwise would have been made without supervision and feedback on image acquisition and interpretation. Nursing staff without ultrasound training can also be directed to perform basic ultrasound exams, which may have immediate diagnostic and/or treatment consequences, thereby overcoming access barriers in the absence of physicians or physician extenders. We discuss 4 real-life clinical scenarios in which teleintensivist supervision extended and standardized bedside ultrasound exams to guide management decisions which significantly impacted patient outcomes.

Pooling score: an endoscopic model for evaluating severity of dysphagia

PubMed Central

Farneti, D

2008-01-01

Summary The finding of secretions and bolus pooling is of great diagnostic interest in the evaluation of subjects with swallowing disorders. Bedside evaluation alone, in subjects at risk for aspiration, can underestimate this parameter. The usefulness of endoscopic investigation for the evaluation of subjects with swallowing disorders is stressed, in order to plan treatment and follow-up. Based on endoscopic evaluation of material pooling we devised a score expressing the severity of dysphagia. This value takes into account endoscopic landmarks and other parameters of bedside evaluation. Endoscopic and bedside data were collected from a heterogeneous population of 520 consecutive patients seen in our Service over a 6-year period. By means of the test of equality of group means and logistic regression, parameters able to significantly predict aspiration in the series were identified. An ordinal number was attributed to each parameter in order to obtain scores expressing three degrees of severity of dysphagia: mild, moderate, severe. The scores can be used to guide the management of patients in a simple way, providing indications for targeted referral to the speech pathologist and for tracking the disorder over time. This investigation represents the basis for future research aimed at validating the scores in a larger case series. PMID:18646575

2012-01-01

We conducted a quality improvement project in order to evaluate the effect of nurse-to-nurse bedside "rounding" as a strategy to decrease hospital-acquired pressure ulcers (HAPU) in a surgical intensive care unit. We instituted weekly peer-to-peer bedside skin rounds in a 17-bed surgical intensive care unit. Two nurses were identified as skin champions and trained by the hospital's certified WOC nurse to conduct skin rounds. The skin champion nurses conducted weekly peer-to-peer rounds that included discussions about key elements of our patients' skin status including current Braden Scale for Pressure Sore Risk score, and implementation of specific interventions related to subscale risk assessment. If a pressure ulcer was present, the current action plan was reevaluated for effectiveness. Quarterly HAPU prevalence studies were conducted from January 2008 to December 2010. Nineteen patients experienced a HAPU: 17 were located on the coccyx and 2 on the heel. Ten ulcers were classified as stage II, 3 PU were stage IV, 5 were deemed unstageable, and 1 was classified as a deep tissue injury. The frequency of preventive interventions rose during our quality improvement project. Specifically, the use of prevention surfaces increased 92%, repositioning increased 30%, nutrition interventions increased 77%, and moisture management increased 100%. Prior to focused nursing rounds, the highest HAPU prevalence rate was 27%. After implementing focused nursing rounds, HAPU rates trended down and were 0% for 3 consecutive quarters.

The introduction of an information system integrated to bedside equipment requires significant financial and resource investment; therefore understanding the potential impact is beneficial for decision-makers. However, no systematic literature reviews (SLRs) focus on this topic. This SLR aims to gather evidence on the impact of the aforementioned system, also known as a patient data management system (PDMS) on both organizational and clinical outcomes. A literature search was performed using the databases Medline/PubMed and CINHAL for English articles published between January 2000 and December 2012. A quality assessment was performed on articles deemed relevant for the SLR. Eighteen articles were included in the SLR. Sixteen articles investigated the impact of a PDMS on the organizational outcomes, comprising descriptive, quantitative and qualitative studies. A PDMS was found to reduce the charting time, increase the time spent on direct patient care and reduce the occurrence of errors. Only two articles investigated the clinical impact of a PDMS. Both reported an improvement in clinical outcomes when a PDMS was integrated with a clinical decision support system (CDSS). A PDMS has shown to offer many advantages in both the efficiency and the quality of care delivered to the patient. In addition, a PDMS integrated to a CDSS may improve clinical outcomes, although further studies are required for validation. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Point of care testing (POCT) must comply with regulatory requirements according to standard EN ISO 22870, which identify biologists as responsible for POCT. INR for vitamin K antagonists (VKAs) monitoring is a test frequently performed in haemostasis laboratories. Bedside INR is useful in emergency room, in particular in case of VKAs overdosage but also for specific populations of patients like paediatrics or geriatrics. INR POCT devices are widely used at home by the patients for self-testing, but their use in the hospital by the clinical staff for bedside measurement is growing, with devices which now comply with standard for POCT accreditation for hospital use. The majority of point of care devices for INR monitoring has shown a good precision and accuracy with results similar to those obtained in laboratory. With the aim to help the multidisciplinary groups for POCT supervision, the medical departments and the biologists to be in accordance with the standard, we present the guidelines of the GFHT (Groupe français d'étude sur l'hémostase et la thrombose, subcommittee "CEC et biologie délocalisée") for the certification of POCT INR. These guidelines are based on the SFBC guidelines for the certification of POCT and on the analysis of the literature to ascertain the justification of clinical need and assess the analytical performance of main analysers used in France, as well as on a survey conducted with biologists.

Neurology has a reputation, particularly as a complex "head-to-toe" discipline for undergraduate medical students. Neurophobia syndrome, a global phenomenon, fundamentally stems from pedagogical deficiencies during the undergraduate curriculum, the lack of vertical integration between basic neurosciences and clinical bedside neurology, the lack of clinical reasoning exercises, cognitive heuristics, and clinical problem-solving, errors in diagnostic competence, and hyposkilia. This ultimately results in poor clinical competence and proficiency in clinical neurology and causes attrition in nurturing a passion for learning the neurology discipline. This article explores plausible factors that contribute to the genesis of neurophobia and multifaceted strategies to nurture interest in neurosciences and provide possible solutions to demystify neurology education, especially the need for evidence-based educational interventions. Remodeling neurology education through effective pedagogical strategies and remedial measures, and using the Miller's pyramid, would provide a framework for assessing clinical competence in clinical bedside neurology. Technology-enhanced education and digital classrooms would undoubtedly stamp out neurophobia in medical students of the 21 st century. It will not frighten off another generation of nonneurologist physicians to empower them to hone expertise in order to tackle the increasing burden of neurological disorders in India. Furthermore, promoting neurophilia would facilitate the next generation of medical students in pursuing career options in neurology which would be quintessential not only in closing India's looming neurologist workforce gap but also in fostering interest in research imperatives in the next generation of medical students.

Objective To investigate the effectiveness of brief bedside “booster” cardiopulmonary resuscitation (CPR) training to improve CPR guideline compliance of hospital-based pediatric providers. Design Prospective, randomized trial. Setting General pediatric wards at Children’s Hospital of Philadelphia. Subjects Sixty-nine Basic Life Support–certified hospital-based providers. Intervention CPR recording/feedback defibrillators were used to evaluate CPR quality during simulated pediatric arrest. After a 60-sec pretraining CPR evaluation, subjects were randomly assigned to one of three instructional/feedback methods to be used during CPR booster training sessions. All sessions (training/CPR manikin practice) were of equal duration (2 mins) and differed only in the method of corrective feedback given to participants during the session. The study arms were as follows: 1) instructor-only training; 2) automated defibrillator feedback only; and 3) instructor training combined with automated feedback. Measurements and Main Results Before instruction, 57% of the care providers performed compressions within guideline rate recommendations (rate >90 min−1 and <120 min−1); 71% met minimum depth targets (depth, >38 mm); and 36% met overall CPR compliance (rate and depth within targets). After instruction, guideline compliance improved (instructor-only training: rate 52% to 87% [p .01], and overall CPR compliance, 43% to 78% [p < .02]; automated feedback only: rate, 70% to 96% [p = .02], depth, 61% to 100% [p < .01], and overall CPR compliance, 35% to 96% [p < .01]; and instructor training combined with automated feedback: rate 48% to 100% [p < .01], depth, 78% to 100% [p < .02], and overall CPR compliance, 30% to 100% [p < .01]). Conclusions Before booster CPR instruction, most certified Pediatric Basic Life Support providers did not perform guideline-compliant CPR. After a brief bedside training, CPR quality improved irrespective of training content (instructor vs. automated feedback). Future studies should investigate bedside training to improve CPR quality during actual pediatric cardiac arrests. PMID:20625336

From bench to FDA to bedside: US regulatory trends for new stem cell therapies.

PubMed

Knoepfler, Paul S

2015-03-01

The phrase "bench-to-bedside" is commonly used to describe the translation of basic discoveries such as those on stem cells to the clinic for therapeutic use in human patients. However, there is a key intermediate step in between the bench and the bedside involving governmental regulatory oversight such as by the Food and Drug Administration (FDA) in the United States (US). Thus, it might be more accurate in most cases to describe the stem cell biological drug development process in this way: from bench to FDA to bedside. The intermediate development and regulatory stage for stem cell-based biological drugs is a multifactorial, continually evolving part of the process of developing a biological drug such as a stem cell-based regenerative medicine product. In some situations, stem cell-related products may not be classified as biological drugs in which case the FDA plays a relatively minor role. However, this middle stage is generally a major element of the process and is often colloquially referred to in an ominous way as "The Valley of Death". This moniker seems appropriate because it is at this point, and in particular in the work that ensues after Phase 1, clinical trials that most drug product development is terminated, often due to lack of funding, diseases being refractory to treatment, or regulatory issues. Not surprisingly, workarounds to deal with or entirely avoid this difficult stage of the process are evolving both inside and outside the domains of official regulatory authorities. In some cases these efforts involve the FDA invoking new mechanisms of accelerating the bench to beside process, but in other cases these new pathways bypass the FDA in part or entirely. Together these rapidly changing stem cell product development and regulatory pathways raise many scientific, ethical, and medical questions. These emerging trends and their potential consequences are reviewed here. Copyright © 2014 Elsevier B.V. All rights reserved.

To determine a) if a checklist covering a diverse group of intensive care unit protocols and objectives would improve clinician consideration of these domains and b) if improved consideration would change practice patterns. Pre- and post observational study. A 24-bed surgical/burn/trauma intensive care unit in a teaching hospital. A total of 1399 patients admitted between June 2006 and May 2007. The first component of the study evaluated whether mandating verbal review of a checklist covering 14 intensive care unit best practices altered verbal consideration of these domains. Evaluation was performed using real-time bedside audits on morning rounds. The second component evaluated whether the checklist altered implementation of these domains by changing practice patterns. Evaluation was performed by analyzing data from the Project IMPACT database after patients left the intensive care unit. Verbal consideration of evaluable domains improved from 90.9% (530/583) to 99.7% (669/671, p < .0001) after verbal review of the checklist was mandated. Bedside consideration improved on the use of deep venous thrombosis prophylaxis (p < .05), stress ulcer prophylaxis (p < .01), oral care for ventilated patients (p < 0.01), electrolyte repletion (p < .01), initiation of physical therapy (p < .05), and documentation of restraint orders (p < .0001). Mandatory verbal review of the checklist resulted in a greater than two-fold increase in transferring patients out of the intensive care unit on telemetry (16% vs. 35%, p < .0001) and initiation of physical therapy (28% vs. 42%, p < .0001) compared with baseline practice. A mandatory verbal review of a checklist covering a wide range of objectives and goals at each patient's bedside is an effective method to improve both consideration and implementation of intensive care unit best practices. A bedside checklist is a simple, cost-effective method to prevent errors of omission in basic domains of intensive care unit management that might otherwise be forgotten in the setting of more urgent care requirements.

Acid Base Disorders (ABDs) are commonly encountered in critically ill Chronic Kidney Disease (CKD) patients. Timely and correct analysis of Arterial Blood Gases (ABG) is critical for the diagnosis, treatment and prediction of outcome of the patients. The aim was to explore type and prevalence of ABDs in 31 critically ill CKD patients from a tertiary care hospital in Maharashtra, to compare two methods of analysis- bedside and systematic approaches and to clinically correlate the nature of ABDs in these patients. The initial ABG reports of 31 consecutive CKD patients were analysed by two methods. Medica Easy stat analyser was the equipment for analysis with Principle of potentiometry and ion selective electrode for pH and pCO2 and amperometry for pO2. Serum albumin was also measured by Bromocresol green dye binding method using liquixx albumin kit in Erba XL 300 autoanalyser. Chi-square test was used for statistical analysis using Epi Info version 3.5.4 and SPSS 14.0 softwares. The systematic method showed a significantly higher prevalence of mixed disorders (50%) compared to bedside method (12.9%). Most prevalent disorder by bedside method was metabolic acidosis in 15 cases (48.39%). By the systematic method, 3 reports were invalid. As a single category, most prevalent type was both simple respiratory alkalosis and mixed metabolic acidosis with respiratory alkalosis- 6 of 31 cases in each type (19.36% each). As a whole, metabolic acidosis (including both High Anion Gap Metabolic Acidosis or HAGMA and Non Anion Gap Metabolic Acidosis or NAGMA with 4 in each type) was most prevalent- 8 of 31(25.8%). Systematic approach was more effective in diagnosing mixed acid base disorders. By systematic method the findings of analysis in most cases could be correlated with the clinical condition and provisional diagnosis. Thus interpretation of ABDs by using stepwise approach could be useful to the clinicians in early diagnosis and management of the patients.

PDA(Patent ductus arteriosus) is a common and clinically important condition which is presented with a number of hemodynamic and respiratory problems such as intraventricular hemorrhage, pulmonary hemorrhage and necrotizing enterocolitis due to increased pulmonary blood flow and stealing from systemic circulation. The incidence of PDA among the infants that were born before the 28th gestational week is as high as 70 %; and spontaneous closure rates in very-low-birth-weight premature neonates(VLBWPN) is around 34 %. The onset, duration, and repeat number of consecutive courses of the prostaglandin synthesis inhibitor medication for PDA closure are still issues of debate. Bed-side PDA closure is a safe surgical procedure in both mature and premature babies. Here we aim to retrospectively present our 26 cases which were less than 28 weeks and 1000 grams that underwent bed-side PDA ligation. This retrospective study included 26 VLBWPN with PDA that underwent bed-side ligation between 2012 and 2015. Babies were born before the 28th gestational week (23-27 weeks) and less than 1000 grams (489-970 gr). Of the 26, 15 were female and 11 were male. Indomethacin was administered to all of the cases as the medical closing agent. The medication was stopped due to unwanted effects in 6 cases. All of the patients took medical treatment before surgery. No surgical mortality occurred during our study. One case of pneumothorax was recorded as late surgical complication. Five of the 26 patients were lost, and the most common cause of mortality was sepsis (in 3 cases). The remaining 21 cases were discharged on days 86-238. The follow-up periods of the patients were 2 moths - 3 years. The most frequent problems encountered after discharge was chronic lung problems. Bed side PDA ligation surgery in the ICU is a safe method for VLBWPN with clinically significant PDA.

Optimal approaches to teaching bedside procedures are unknown. To identify effective instructional approaches in procedural training. We searched PubMed, EMBASE, Web of Science and Cochrane Library through December 2014. We included research articles that addressed procedural training among physicians or physician trainees for 12 bedside procedures. Two independent reviewers screened 9312 citations and identified 344 articles for full-text review. Two independent reviewers extracted data from full-text articles. We included measurements as classified by translational science outcomes T1 (testing settings), T2 (patient care practices) and T3 (patient/public health outcomes). Due to incomplete reporting, we post hoc classified study outcomes as 'negative' or 'positive' based on statistical significance. We performed meta-analyses of outcomes on the subset of studies sharing similar outcomes. We found 161 eligible studies (44 randomised controlled trials (RCTs), 34 non-RCTs and 83 uncontrolled trials). Simulation was the most frequently published educational mode (78%). Our post hoc classification showed that studies involving simulation, competency-based approaches and RCTs had higher frequencies of T2/T3 outcomes. Meta-analyses showed that simulation (risk ratio (RR) 1.54 vs 0.55 for studies with vs without simulation, p=0.013) and competency-based approaches (RR 3.17 vs 0.89, p<0.001) were effective forms of training. This systematic review of bedside procedural skills demonstrates that the current literature is heterogeneous and of varying quality and rigour. Evidence is strongest for the use of simulation and competency-based paradigms in teaching procedures, and these approaches should be the mainstay of programmes that train physicians to perform procedures. Further research should clarify differences among instructional methods (eg, forms of hands-on training) rather than among educational modes (eg, lecture vs simulation).

Resource scarcity in health care is a universal challenge. In high-income settings, bedside rationing is commonly discussed and debated as a means to addressing scarcity. However, little is known about physicians' experiences in resource-limited contexts in low- income countries. Here we describe physicians' experiences regarding scarcity of resources, bedside rationing, use of various strategies to save resources, and perceptions of the consequences of rationing in Ethiopia. A national survey was conducted amongst physicians from 49 public hospitals using stratified, multi-stage sampling in six regions. All physicians in the selected hospitals were invited to respond to a self-administered questionnaire. Data were weighted and analyzed using descriptive statistics. In total, 587 physicians responded (91% response rate). The majority had experienced system-wide shortages of various types of medical services. The services most frequently reported to be in short supply, either daily or weekly, were access to surgery, specialist and intensive care units, drug prescriptions and admission to hospital (52, 49, 46, 47 and 46% respectively). The most common rationing strategies used daily or weekly were limiting laboratory tests, hospital drugs, radiological investigations and providing second best treatment (47, 47, 47 and 39% respectively). Availability of institutional or national guidelines for whom to see and treat first was lacking. Almost all respondents had witnessed different adverse consequences of resource scarcity; 54% reported seeing patients who, in their estimation, had died due to resource scarcity. Almost 9 out of 10 physicians were so troubled by limited resources that they often regretted their choice of profession. This study provides the first glimpses of the untold story of resource shortage and bedside rationing in Ethiopia. Physicians encounter numerous dilemmas due to resource scarcity, and they report they lack adequate guidance for how to handle them. The consequences for patients and the professionals are substantial.

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

Contamination of hospital surfaces by bacteria is increasingly recognized. We assessed commonly touched surfaces using contact plates and Petrifilms (3M, St. Paul, MN) and compared the results against proposed microbiology standards. Toilet door handles were the most heavily contaminated (7.97 ± 0.68 colony forming units [CFU]/cm(2)) and exceeded proposed standards on 74% of occasions. Petrifilms detected statistically higher CFU from bedside lockers. Further research is required on the use of standards and methods of sampling.

Redox-Directed Cancer Therapeutics: Molecular Mechanisms and Opportunities

PubMed Central

2009-01-01

Abstract Redox dysregulation originating from metabolic alterations and dependence on mitogenic and survival signaling through reactive oxygen species represents a specific vulnerability of malignant cells that can be selectively targeted by redox chemotherapeutics. This review will present an update on drug discovery, target identification, and mechanisms of action of experimental redox chemotherapeutics with a focus on pro- and antioxidant redox modulators now in advanced phases of preclinal and clinical development. Recent research indicates that numerous oncogenes and tumor suppressor genes exert their functions in part through redox mechanisms amenable to pharmacological intervention by redox chemotherapeutics. The pleiotropic action of many redox chemotherapeutics that involves simultaneous modulation of multiple redox sensitive targets can overcome cancer cell drug resistance originating from redundancy of oncogenic signaling and rapid mutation. Moreover, some redox chemotherapeutics may function according to the concept of synthetic lethality (i.e., drug cytotoxicity is confined to cancer cells that display loss of function mutations in tumor suppressor genes or upregulation of oncogene expression). The impressive number of ongoing clinical trials that examine therapeutic performance of novel redox drugs in cancer patients demonstrates that redox chemotherapy has made the crucial transition from bench to bedside.

This article provides an overview of the current status of simulator systems in robotic surgery training curriculum, focusing on available simulators for training, their comparison, new technologies introduced in simulation focusing on concepts of training along with existing challenges and future perspectives of simulator training in robotic surgery. The different virtual reality simulators available in the market like dVSS, dVT, RoSS, ProMIS and SEP have shown face, content and construct validity in robotic skills training for novices outside the operating room. Recently, augmented reality simulators like HoST, Maestro AR and RobotiX Mentor have been introduced in robotic training providing a more realistic operating environment, emphasizing more on procedure-specific robotic training . Further, the Xperience Team Trainer, which provides training to console surgeon and bed-side assistant simultaneously, has been recently introduced to emphasize the importance of teamwork and proper coordination. Simulator training holds an important place in current robotic training curriculum of future robotic surgeons. There is a need for more procedure-specific augmented reality simulator training, utilizing advancements in computing and graphical capabilities for new innovations in simulator technology. Further studies are required to establish its cost-benefit ratio along with concurrent and predictive validity.

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

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

The aim of this study was to investigate the feasibility of simultaneous visualization of the cerebral macrocirculation and microcirculation, using ultrasound perfusion imaging (UPI). In addition, we studied the sensitivity of this technique for detecting changes in cerebral blood flow (CBF). We performed an observational study in ten healthy volunteers. Ultrasound contrast was used for UPI measurements during normoventilation and hyperventilation. For the data analysis of the UPI measurements, an in-house algorithm was used to visualize the DICOM files, calculate parameter images and select regions of interest (ROIs). Next, time intensity curves (TIC) were extracted and perfusion parameters calculated. Both volume- and velocity-related perfusion parameters were significantly different between the macrocirculation and the parenchymal areas. Hyperventilation-induced decreases in CBF were detectable by UPI in both the macrocirculation and microcirculation, most consistently by the volume-related parameters. The method was safe, with no adverse effects in our population. Bedside quantification of CBF seems feasible and the technique has a favourable safety profile. Adjustment of current method is required to improve its diagnostic accuracy. Validation studies using a 'gold standard' are needed to determine the added value of UPI in neurocritical care monitoring.

Medical immunology in The Netherlands is a laboratory specialism dealing with immunological analyses as well as pre- and post-analytical consultation to clinicians (clinical immunologists and other specialists) involved in patients with immune mediated diseases. The scope of medical immunology includes immunodeficiencies, autoimmune diseases, allergy, transfusion and transplantation immunology, and lymphoproliferative disorders plus the monitoring of these patients. The training, professional criteria, quality control of procedures and laboratories is well organized. As examples of the bridge function of medical immunology between laboratory (bench) and patient (bedside) the contribution of medical immunologists to diagnosis and treatment of primary immunodeficiency diseases (in particular: humoral immunodeficiencies) as well as autoantibodies (anti-citrullinated proteins in rheumatoid arthritis) are given.

Krummel, Thomas M

2006-11-01

Progress in surgical science has been characterized by a continuous cycle of innovation from bedside to bench to bedside. Beginning 30,000 years ago with the first bone needles to surgical lasers and robotics of today, each quantum leap has resulted from the convergence of technical advances and creative surgeons, but always defined by an attitude of care toward the sick. One of the most innovative pediatric surgeons, Dr. Mark Ravitch, elucidated some simple yet profound principles in the precise answer to the question "What is Surgery?" This section outlines some simple concepts summarized as "Ravitch's Rules," which provide a useful framework for clarity in understanding the past and illuminating the road ahead. Surgeons must be thoughtful in how they define themselves and their craft, ignoring technological advances at their own peril.

[Purpose] The purpose of this study was to investigate the effect of self-exercise on oropharyngeal swallowing function in patients with dysphagia. [Subjects and Methods] Nine patients with dysphagia after stroke were recruited. Self-exercise including effortful swallowing, tongue strengthening, and shaker exercise was performed 5 times a week for 4 weeks. Swallowing function was evaluated using the videofluoroscopic dysphagia scale (VDS) based on a videofluoroscopic swallowing study. [Results] There were significant differences in both the oral and pharyngeal phases of the VDS before and after the intervention. [Conclusion] This study demonstrated that bedside self-exercise is a positive method to improve oropharyngeal swallowing function in patients with dysphagia after stroke. PMID:29184294

Pharmacogenomics is emerging as a popular type of study for human genetics in recent years. This is primarily due to the many success stories and high potential for translation to clinical practice. In this review, the strengths and limitations of pharmacogenomics are discussed as well as the primary epidemiologic, clinical trial, and in vitro study designs implemented. A brief discussion of molecular and analytic approaches will be reviewed. Finally, several examples of bench-to-bedside clinical implementations of pharmacogenetic traits will be described. Pharmacogenomics continues to grow in popularity because of the important genetic associations identified that drive the possibility of precision medicine.

This paper presents a proof-of-concept design of a patient monitoring solution for Intensive Care Unit (ICU). It is end-to-end standards-based, using ISO/IEEE 11073 (X73) in the bedside environment and EN13606 to communicate the information to an Electronic Healthcare Record (EHR) server. At the bedside end a plug-and-play sensor network is implemented, which communicates with a gateway that collects the medical information and sends it to a monitoring server. At this point the server transforms the data frame into an EN13606 extract, to be stored on the EHR server. The presented system has been tested in a laboratory environment to demonstrate the feasibility of this end-to-end standards-based solution.

Inflammatory cytokines in amniotic fluid are markers of prematurity which could characterize preterm labour of infectious origin. To avoid amniocentesis, we analyzed IL-6, IL-8, IL-10, and IL-13 by RT-PCR in cervical secretions (CS) of 307 women with preterm labour. IL-6 was detected in 26.3% patients who delivered at less than 34 weeks (specificity: 95.8%). In addition, IL-6 was associated with delivery within 7 days (specificity: 91.6%). To render the detection more rapid and cheaper, a strip test was designed and evaluated comparatively with RT-PCR in 76 women. This bedside strip test was twice more sensitive than RT-PCR, with little decrease in specificity.

Specialty pharmaceuticals: policy initiatives to improve assessment, pricing, prescription, and use.

PubMed

Robinson, James C; Howell, Scott

2014-10-01

The value of "specialty pharmaceuticals" for cancer and other complex conditions depends not merely on their molecular structures but also on the manner in which the drugs are assessed, insured, priced, prescribed, and used. This article analyzes the five principal stages through which a specialty drug must pass on its journey from the laboratory to the bedside. These include regulatory approval by the Food and Drug Administration for market access, insurance coverage, pricing and payment, physician prescription, and patient engagement. If structured appropriately, each stage improves performance and supports continued research and development. If structured inappropriately, however, each stage adds to administrative burdens, distorts clinical decision making, and weakens incentives for innovation. Cautious optimism is in order, but neither the continued development of breakthrough products nor their use according to evidence-based guidelines can be taken for granted.

Ventricular assist devices provide therapeutic options for patients with severe heart failure who have exhausted available medical therapies. With restoration of organ perfusion with ventricular assist devices, the heart failure resolves and quality of life and functional status improve. The current generation of continuous-flow devices present novel challenges to the clinical assessment of patients by substantially reducing or nearly eliminating any palpable pulse. Patients therefore generally have inadequate arterial pulsatility for most noninvasive monitoring devices such as pulse oximeters or automated blood pressure cuffs to work accurately. This article describes the function of continuous-flow devices and how this function affects common monitoring options, as well as how to clinically assess recipients of continuous-flow devices to promptly identify those whose condition may be deteriorating or who may be receiving inadequate perfusion.

Elderly people at risk of developing cognitive decline; e.g., following surgery, may benefit from structured, challenging, and repetitive cognitive video training. This study assessed usability and acute effects of a newly developed bedside console (COPHYCON). Fifteen healthy elderly individuals performed a one-time 80-min intervention, including cognitive video games aimed at improving awareness and selective attention. Perceived usefulness and perceived ease of use (Technology Acceptance Model) were assessed together with measures of the achieved game level, reaction times, (in-) correct responses during ALERT and SELECT game play. Further, prefrontal cortical involvement of the regional cerebral hemoglobin saturation (rS02%) assessed with functional near infrared spectroscopy (fNIRS) ( n = 5) and EEG power ( n = 10) was analyzed. All participants completed the study without any adverse events. Perceived usefulness and perceived ease of use (TAM scores range 1-7) of the system varied between 3.9 and 6.3. The game levels reached for awareness varied between 9 and 11 (initial score 8-10), for reaction speed between 439 and 469 ms, and for correct responses between 74.1 and 78.8%. The highest level for the selective attention games was 2 (initial score 1), where reaction speed varied between 439 and 469 ms, correct responses between 96.2 and 98.5%, respectively. The decrease of rS02% in the right prefrontal cortex during gameplay was significantly ( p < 0.001) lower, compared to the left prefrontal cortex. Four participants yielded significant lower rS02% measures after exergaming with the ALERT games ( p < 0.000), but not with the SELECT games. EEG recordings of theta power significantly decreased in the averaged ~0.25-0.75 time interval for the left prefrontal cortex sensor across the cognitive game levels between the ALERT 1 and SELECT 1, as well as between SELECT 1 and 2 games. Participants rated the usability of the COPHYCON training positively. Further results indicate that video gaming may be an effective measure to affect prefrontal cortical functioning in elderly. The results warrant a clinical explorative study investigating the feasibility of the COPHYCON in a clinical setting.

Recognition of pediatric sepsis is a key clinical challenge. We evaluate the performance of a sepsis recognition process including an electronic sepsis alert and bedside assessment in a pediatric emergency department (ED). This was a cohort study with quality improvement intervention in a pediatric ED. Exposure was a positive electronic sepsis alert, defined as elevated pulse rate or hypotension, concern for infection, and at least one of the following: abnormal capillary refill, abnormal mental status, or high-risk condition. A positive electronic sepsis alert prompted team assessment or huddle to determine need for sepsis protocol. Clinicians could initiate team assessment or huddle according to clinical concern without positive electronic sepsis alert. Severe sepsis outcome defined as activation of the sepsis protocol in the ED or development of severe sepsis requiring ICU admission within 24 hours. There were 182,509 ED visits during the study period, with 86,037 before electronic sepsis alert implementation and 96,472 afterward, and 1,112 (1.2%) positive electronic sepsis alerts. Overall, 326 patients (0.3%) were treated for severe sepsis within 24 hours. Test characteristics of the electronic sepsis alert alone to detect severe sepsis were sensitivity 86.2% (95% confidence interval [CI] 82.0% to 89.5%), specificity 99.1% (95% CI 99.0% to 99.2%), positive predictive value 25.4% (95% CI 22.8% to 28.0%), and negative predictive value 100% (95% CI 99.9% to 100%). Inclusion of the clinician screen identified 43 additional electronic sepsis alert-negative children, with severe sepsis sensitivity 99.4% (95% CI 97.8% to 99.8%) and specificity 99.1% (95% CI 99.1% to 99.2%). Electronic sepsis alert implementation increased ED sepsis detection from 83% to 96%. Electronic sepsis alert for severe sepsis demonstrated good sensitivity and high specificity. Addition of clinician identification of electronic sepsis alert-negative patients further improved sensitivity. Implementation of the electronic sepsis alert was associated with improved recognition of severe sepsis. Copyright © 2017 American College of Emergency Physicians. Published by Elsevier Inc.

Sensitivity of bedside ultrasound and supine anteroposterior chest radiographs for the identification of pneumothorax after blunt trauma.

PubMed

Wilkerson, R Gentry; Stone, Michael B

2010-01-01

Supine anteroposterior (AP) chest radiographs in patients with blunt trauma have poor sensitivity for the identification of pneumothorax. Ultrasound (US) has been proposed as an alternative screening test for pneumothorax in this population. The authors conducted an evidence-based review of the medical literature to compare sensitivity of bedside US and AP chest radiographs in identifying pneumothorax after blunt trauma. MEDLINE and EMBASE databases were searched for trials from 1965 through June 2009 using a search strategy derived from the following PICO formulation of our clinical question: patients included adult (18 + years) emergency department (ED) patients in whom pneumothorax was suspected after blunt trauma. The intervention was thoracic ultrasonography for the detection of pneumothorax. The comparator was the supine AP chest radiograph during the initial evaluation of the patient. The outcome was the diagnostic performance of US in identifying the presence of pneumothorax in the study population. The criterion standard for the presence or absence of pneumothorax was computed tomography (CT) of the chest or a rush of air during thoracostomy tube placement (in unstable patients). Prospective, observational trials of emergency physician (EP)-performed thoracic US were included. Trials in which the exams were performed by radiologists or surgeons, or trials that investigated patients suffering penetrating trauma or with spontaneous or iatrogenic pneumothoraces, were excluded. The methodologic quality of the studies was assessed. Qualitative methods were used to summarize the study results. Data analysis consisted of test performance (sensitivity and specificity, with 95% confidence intervals [CIs]) of thoracic US and supine AP chest radiography. Four prospective observational studies were identified, with a total of 606 subjects who met the inclusion and exclusion criteria. The sensitivity and specificity of US for the detection of pneumothorax ranged from 86% to 98% and 97% to 100%, respectively. The sensitivity of supine AP chest radiographs for the detection of pneumothorax ranged from 28% to 75%. The specificity of supine AP chest radiographs was 100% in all included studies. This evidence-based review suggests that bedside thoracic US is a more sensitive screening test than supine AP chest radiography for the detection of pneumothorax in adult patients with blunt chest trauma.

Involvement of family in bedside rounds is one strategy to implement family-centered care to help families get clear information about their child, and be actively involved in decision-making about care. However in developing countries such as Pakistan, daily bedside rounds include the physician, residents, medical students and a nurse/technician. Parents are not currently a part of these rounds. To assess whether family-centered rounds improve parents' and health care professionals' satisfaction, decrease patient length of stay, and improve time utilization when compared to traditional practice rounds in a population with a low literacy rate, socioeconomic status, and different cultural values and beliefs. A non-randomized before-after study design. A private hospital in Karachi, Pakistan. A convenience sample of 82 parents, whose children were hospitalized for a minimum of 48h, and 25 health care professionals able to attend two consecutive rounds. During the before phase, traditional bedside rounds were practiced; and during after phase, family-centered rounds were practiced. Parents and health care professionals completed a questionnaire on the second day of rounds. An observational form facilitated data collection on length of stay and time utilization during. Parents' ratings during the family-centered rounds were significantly higher for some parental satisfaction items: evidence of team work (p=0.007), use of simple language during the rounds (p=0.002), feeling of inclusion in discussion at rounds (p=0.03), decision making (p=0.01), and preference for family-centered rounds (p=<0.001). No significant differences were found in health care professionals' satisfaction between rounds. Patient length of stay was significantly reduced in the family-centered rounds group, while no significant difference was found in the duration of rounds. Family-centered rounds served as an opportunity for parents to correct/add to patient history or documentation. Parents were satisfied with both forms of rounds; however, they appeared to have a greater preference for family-centered rounds than health care professionals. Family-centered rounds were a resource for Pakistani parents, enabling direct communication with the medical team without impacting on the time required to complete rounds. Family-centered rounds may improve quality of care such as decreasing length of stay or preventing critical incidents. Copyright © 2012 Elsevier Ltd. All rights reserved.

CLINICAL AUDIT OF IMAGE QUALITY IN RADIOLOGY USING VISUAL GRADING CHARACTERISTICS ANALYSIS.

Tesselaar, Erik; Dahlström, Nils; Sandborg, Michael

2016-06-01

The aim of this work was to assess whether an audit of clinical image quality could be efficiently implemented within a limited time frame using visual grading characteristics (VGC) analysis. Lumbar spine radiography, bedside chest radiography and abdominal CT were selected. For each examination, images were acquired or reconstructed in two ways. Twenty images per examination were assessed by 40 radiology residents using visual grading of image criteria. The results were analysed using VGC. Inter-observer reliability was assessed. The results of the visual grading analysis were consistent with expected outcomes. The inter-observer reliability was moderate to good and correlated with perceived image quality (r(2) = 0.47). The median observation time per image or image series was within 2 min. These results suggest that the use of visual grading of image criteria to assess the quality of radiographs provides a rapid method for performing an image quality audit in a clinical environment. © The Author 2015.

2015-05-01

Vestibular function (specifically, horizontal semicircular canal function) can be assessed across a broad frequency range using several different techniques. The head impulse test is a qualitative test of horizontal semicircular canal function that can be completed at bedside. Recently, a new instrument (video head impulse test [vHIT]) has been developed to provide an objective assessment to the clinical test. Questions persist regarding how this test may be used in the overall vestibular test battery. The purpose of this case report is to describe vestibular test results (vHIT, rotational testing, vestibular evoked myogenic potentials, and balance and gait performance) in an individual with a 100% unilateral caloric weakness who was asymptomatic for dizziness, vertigo or imbalance. Comprehensive assessment was completed to evaluate vestibular function. Caloric irrigations, rotary chair testing, vHIT, and vestibular evoked myogenic potentials were completed. A 100% left-sided unilateral caloric weakness was observed in an asymptomatic individual. vHIT produced normal gain with covert saccades. This case demonstrates the clinical usefulness of vHIT as a diagnostic tool and indicator of vestibular compensation and functional status. American Academy of Audiology.

Bedside ultrasonography has an increasing role in medicine yet medical students have limited exposure. Although countless hours are devoted to plain radiograph and electrocardiogram (ECG) interpretation, ultrasound is frequently glossed over. Yet this imaging modality could enhance students' understanding of anatomy, physiology and pathology, and may increase their integration into hospital teams. We aimed to investigate whether a peer-assisted ultrasound course has a place within the undergraduate medical curriculum. We describe the implementation of a course and discuss its acceptability and utility in student education. Bedside ultrasonography has an increasing role in medicine yet medical students have limited exposure METHODS: Following consultation with the medical school, an improved ultrasonography course was developed with expert guidance from an ultrasonographer and with new equipment. Sessions involved peer-tutors teaching ultrasonography techniques to medical students during emergency medicine placements. Tutees completed questionnaires to assess the quality and perceived benefits of the course and of learning ultrasonography. Both quantitative and thematic analyses of the responses were conducted by the authors. Over a period of 8 months, 105 medical students received teaching across four sessions. A total of 103 students (98%) returned questionnaires on their evaluation of the course and tutors, and on their confidence in using ultrasound. Ninety-eight per cent felt that the teaching was well delivered, 100 per cent felt that their knowledge of ultrasound had improved and 100 per cent would recommend the course. The peer-assisted ultrasound course described here enabled the majority of students to feel confident gaining elementary ultrasound views, and performing abdominal aneurysm screening and trauma assessments: techniques that they could hopefully put to use during their placements. The peer-assisted model has an acceptable role in teaching emerging clinical skills to medical students. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Objective Babies receive oxygen through their umbilical cord while in the uterus and for a few minutes after birth. Currently, if the baby is not breathing well at birth, the cord is cut so as to transfer the newborn to a resuscitation unit. We sought to develop a mobile resuscitation trolley on which newly born babies can be resuscitated while still receiving oxygenated blood and the ‘placental transfusion’ through the umbilical cord. This would also prevent separation of the mother and baby in the first minutes after birth. Design Multidisciplinary iterative product development. Setting Clinical Engineering Department of a University Teaching Hospital. Methods Following an initial design meeting, a series of prototypes were developed. At each stage, the prototype was reviewed by a team of experts in the laboratory and in the hospital delivery suite to determine ease of use and fitness for purpose. A commercial company was identified to collaborate on the trolley's development and secure marking with the Conformité Européenne mark, allowing the trolley to be introduced into clinical practice. Results The trolley is a small mobile resuscitation unit based on the concept of an overbed hospital table. It can be manoeuvred to within 50 cm of the mother's pelvis so that the umbilical cord can remain intact during resuscitation, irrespective of whether the baby is born naturally, by instrumental delivery or by caesarean section. Warmth for the newborn comes from a heated mattress and the trolley has the facility to provide suction, oxygen and air. Conclusions This is the first mobile resuscitation device designed specifically to facilitate newborn resuscitation at the bedside and with an intact cord. The next step is to assess its safety, its acceptability to clinicians and parents, and to determine whether it allows resuscitation with an intact cord. PMID:26191414

Silent aspiration is common after stroke and can lead to subsequent pneumonia. While standard bedside dysphagia assessments are ineffective at predicting silent aspiration, cough reflex testing (CRT) has shown promise for identifying patients at risk of silent aspiration. We investigated the impact of CRT on patient and service outcomes when embedded into a clinical pathway. 488 acute stoke patients were randomly allocated to receive either CRT or standard care (i.e. bedside assessment). Primary outcomes included confirmed pneumonia within 3 months post stroke and length of acute inpatient stay. Secondary outcomes related to the feasibility of implementing a CRT pathway and clinician and patient satisfaction. There was a non-significant reduction in pneumonia rates by 2.2% points in the CRT group (OR 0.32, 95% CI 0.06-1.62). There was a non-significant difference of 0.7 days (95% CI - 0.29 to 1.71 days) in length of stay between the standard care group and the CRT group. The CRT took on average 3 min longer to complete (p < 0.01) and resulted in a significant 6.7% increase in videofluoroscopic referrals (p = 0.02); however, these results are clinically insignificant. High patient and clinician satisfaction with CRT was found, with clinicians reporting additional knowledge and confidence in decision making for dysphagia management. Post hoc subgroup analyses according to stroke types were conducted and revealed no significant differences in pneumonia rates after adjustment for multiple comparisons. In conclusion, it was possible to implement a CRT pathway with minimal increases in clinician resources. While clinicians perceived CRT as beneficial in clinical decision making, the efficacy of CRT for reducing pneumonia rates in acute stroke remains to be established.Clinical Trial Registration-URL: http://www.anzctr.org.au .

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.
