Standardized High-Quality Processes for End-of-Life-Decision Making in the Intensive Care Unit Remain Robust during an Unprecedented New Pandemic-A Single-Center Experience.

Due to the global COVID-19 pandemic, a concomitant increase in awareness for end-of-life decisions (EOLDs) and advance care planning has been noted. Whether the dynamic pandemic situation impacted EOLD-processes on the intensive care unit (ICU) and patient-sided advance care planning in Germany is unknown. This is a retrospective analysis of all deceased patients of surgical ICUs of a university medical center from March 2020 to July 2021. All included ICUs had established standardized protocols and documentation for EOLD-related aspects of ICU therapy. The frequency of EOLDs and advance directives and the process of EOLDs were analyzed (No. of ethical approval EA2/308/20). A total number of 319 (85.5%) of all deceased patients received an EOLD. Advance directives were possessed by 83 (22.3%) of the patients and a precautionary power of attorney by 92 (24.7%) of the patients. There was no difference in the frequency of EOLDs and patient-sided advance care planning between patients with COVID-19 and non-COVID-19 patients. In addition, no differences in frequencies of do-not-resuscitate orders, withholding or withdrawing of intensive care medicine therapeutic approaches, timing of EOLDs, and participation of senior ICU attendings in EOLDs were noted between patients with COVID-19 and non-COVID-19 patients. Documentation of family conferences occurred more often in deceased patients with COVID-19 compared to non-COVID-19 patients (COVID-19: 80.0% vs. non-COVID-19: 56.8, p = 0.001). Frequency of EOLDs and completion rates of advance directives remained unchanged during the pandemic compared to pre-pandemic years. The EOLD process did not differ between patients with COVID-19 and non-COVID-19 patients. Institutional standard procedures might contribute to support the robustness of EOLD-making processes during unprecedented medical emergencies, such as new pandemic diseases.

Development of pediatric multidisciplinary extracorporeal membrane oxygenation simulations: A novel educational program to enhance team communication and emergency preparedness.

Pediatric extracorporeal membrane oxygenation (ECMO) is a high risk, low-volume technology. Infrequency of this technology and associated complications may translate to unfamiliarity of identification and management of potentially life-threatening events, which may require knowledge and procedural skills to be performed quickly. Providers involved in managing ECMO must be able to promptly identify and initiate management for such events, particularly when surgical colleagues are not readily available. A multidisciplinary ECMO simulation program was implemented in a tertiary children's hospital. Over 18months, a prospective, observational study was conducted evaluating simulations involving circuit and patient emergencies, teamwork and communication behaviors and technical skills. An on-line survey was sent to participants following sessions to evaluate post-simulation confidence, lessons learned and potential barriers to implementation of necessary skills and behaviors. Ten simulation sessions occurred during implementation. Mean participants per session was 7 (range: 5-11). Eight Pediatric Cardiac Intensive Care Unit attendings, four Advance Practice Nurses, 54 pediatric intensive care unit registered nurses, and 55 pediatric respiratory therapists attended. Tasks with highest self-reported increase in confidence were related to (1) diagnosis (tension pneumothorax, oxygenator failure, and ventricular tachycardia), (2) fluid administration and (3) early and efficient mobilization for ECPR, with less reported confidence increase with technical skills More than 90% of participants provided a task or behavior they would implement if a specific emergency was encountered in real-life following simulation training. Real-life application occurred following simulations with participants reporting direct impact of training on their ability to perform the skill efficiently and correctly. Implementation of ECMO multidisciplinary simulations provides structured opportunities for the team to learn and practice ECMO skills together in scenarios they may encounter without surgical presence. Ensuring competency of providers through implementation of such a program may improve patient safety through enhanced team communication, knowledge, and hands-on experience.

Opioid Prescribing Behaviors Among Surgical Intensive Care Unit Attending Physicians.

More than 5 million Americans misuse opioids. Six percent of patients who receive opioids for acute pain progress to chronic use; this increases with higher doses and longer prescriptions. Prescribing variation exists within trauma centers and after emergency surgery but has not been demonstrated among intensivists. Milligram morphine equivalents (MME) per patient-ICU-day provided by eleven surgical intensivists were analyzed. The patients were separated into 2 groups based on their percentage of time intubated in the surgical ICU. Both study groups were compared using demographics and comorbidity scores. The attendings were divided into high- and low-prescribing groups based on their MME/pt-ICU-day for intubated patients, and bivariate statistical analyses were performed. A similar analysis compared surgery vs anesthesia intensivists. The analysis included 257 patients in the "long-vent group" (LVG) and 668 patients in the "short-vent group" (SVG). The average MME/pt-ICU-day for the LVG was 222. Despite no significant differences in age, sex, or Elixhauser Comorbidity Index, there was a 45% difference between the high- and low-prescribing physicians in the LVG (253.7 vs 175.4 MME/pt-ICU-day; P = .008). This difference was not observed for patients in the SVG (74.3 vs 93.1 MME/pt-ICU-day; P = .141) nor based on intensivist specialty (LVG: 217.9 vs 209.5 MME/pt-ICU-day; P = .8) (SVG: 79.0 vs 93.3 MME/pt-ICU-day; P = .288).

ICU TRANSITION OF CARE

TOPIC: Education, Research, and Quality Improvement TYPE: Original Investigations PURPOSE: The aim of our project is to formulate a standardized process for transfering patients from the intensive care unit to the medical wards which improves documentation, policy and puts emphasis on communication through a multidisciplinary approach by utilization of a novel hand-off template and implementation of transfer medication reconciliation. METHODS: Following the IHI model, a fishbone diagram was used to identify areas of improvement in the hand-off process. The persons involved, process, policy, and communication were identified as contributing factors in formulating a standardized Transition Of Care (TOC) process. PDSA cycles were used to test change. We measure use of proposed standardized TOC method and number of ICU re-admissions as part of adverse events. RESULTS: After observing the need for this process to become ubiquitous, using the Plan Do Study Act (PDSA) cycle, literature was reviewed, and a TOC template was formulated in PDSA1 which resulted in no significant change. In PDSA2, there was creation of a policy to utilize an existing Transfer Medication Reconciliation (Med Rec.) with our EMR prior to transferring a patient out of ICU. Internal medicine residents, faculty, ICU attendings, ICU committee, ICU Pharmacy, and EMR Department were educated on the implementation of the new procedure was initiated. 100 charts were analyzed post-intervention; of those 61 charts met inclusion criteria. Twenty seven of the 61 charts had an appropriate use of the TOC Template and use of Transfer Med Rec. in addition to communication with the primary attending (44%). Of these, there was 1 Rapid Response (RR) that warranted an ICU readmission (3.7%). There were 0 code blues after transfer from ICU. Of the 34 charts that did not abide to procedure, there were 3 RRs (8.8%). CONCLUSIONS: There were fewer RR when comparing the patients with the ICU TOC implemented compared to those without the documented communication (3.7% vs 8.8%). The ICU readmission noted, should take into account the inherit fragility of this patient population and associated morbidly. Despite our small sample size, the trends are promising that align with the impact of our implementation of ICU TOC process.The goal of this QI project was to use a multisystem approach to standardized transfer process to ensure patient safety. In our next PDSA cycle, there will be a pop-up screen when a Transfer Order out of ICU is clicked, that directs user to Transfer Med Rec. page before proceeding. With this new implementation, there will be an increased compliance to abiding to the process with integration of the EMR with Transfer Med Rec. CLINICAL IMPLICATIONS: The transition of patient care from the Intensive Care Unit (ICU) to the medical wards has been identified as a crucial time for communication and accuracy in these patients who are at high risk for potential harm due to medical errors. Proper transition process is critical, as the lack of a universal standardized hand-off could lead to detrimental consequences. Our community hospital has an “open” ICU and inconsistent transition of care process has been observed. The focus of our project is to formulate a standardized transfer process that improves documentation, policy and puts emphasis on communication through a multidisciplinary approach with utilization of a hand-off template and implementation of transfer medication reconciliation.

Putting Prognosis First: Impact of an Intensive Care Unit Team Premeeting Curriculum.

Background: The paradigm of care has shifted in the pediatric intensive care unit (ICU) such that patients are frequently cared for by teams of specialists rather than the ICU attending physician solely managing care. An unintended consequence of care managed by multiple specialists is that families often receive conflicting messages from different team members, with little focus on disclosing prognosis.Objective: To address this gap, we developed and pilot-tested a team communication skills training (CST) program focused on the healthcare team premeeting in which roles, purpose, and prognosis are clarified before meeting with the family. Our aim was to assess whether the team CST program was associated with increased discussion of prognosis during the team premeeting.Methods: We conducted a single-center, observational pilot study to develop and test a team CST program using a before/after design. Pediatric ICU physicians and specialists from pediatric neurology and pediatric oncology who co-led family conferences in the pediatric ICU participated in a 1-day team CST program. Team premeetings were audio-recorded and transcribed.Results: We analyzed seven pre- and 10 post-CST program audio-recorded team premeetings, which each compromised a median of eight healthcare team members. Prognosis was more likely to be discussed in post-CST team premeetings (10/10 vs. 3/7; P = 0.0147). Agreement on prognosis was achieved more frequently in post-CST teams compared with pre-CST teams, although the percentage of agreement did not reach significance (9/10 vs. 3/7; P = 0.1007).Conclusions: A CST program with a structured approach to conducting a team premeeting was associated with an increased discussion of prognosis among team members before convening with the family in the pediatric ICU.

What Affects Adoption of Specialty Palliative Care in Intensive Care Units: A Qualitative Study

ContextAlthough many patients with critical illness may benefit from involvement of palliative care specialists, adoption of these services in the intensive care unit (ICU) is variable. ObjectiveTo characterize reasons for variable buy-in for specialty palliative care in the ICU, and identify factors associated with routine involvement of specialists in appropriate cases. MethodsQualitative study using in-depth, semi-structured interviews with ICU attendings, nurses, and palliative care clinicians, purposively sampled from eight ICUs (medical, surgical, cardiothoracic, neurological) with variable use of palliative care services within two urban, academic medical centers. Interviews were transcribed and coded using an iterative and inductive approach with constant comparison. ResultsWe identified three types of specialty palliative care adoption in ICUs, representing different phases of buy-in. The “nascent” phase was characterized by the need for education about palliative care services and clarification of which patients may be appropriate for involvement. During the key “transitional” phase, use of specialists depended on development of “comfort and trust”, which centered on four aspects of the ICU-palliative care clinician relationship: 1) increasing familiarity between clinicians; 2) navigating shared responsibility with primary clinicians; 3) having a collaborative approach to care; and 4) having successful experiences. In the “mature” phase, ICU and palliative care clinicians worked to strengthen their existing collaboration, but further adoption was limited by the availability and resources of the palliative care team. ConclusionThis conceptual framework identifying distinct phases of adoption may assist institutions aiming to foster sustained adoption of specialty palliative care in an ICU setting.

Structure and concept of ICU rounds: the VIS-ITS survey.

ObjectiveTo gather data about structural and procedural characteristics of patient rounds in the intensive care unit (ICU) setting.DesignA structured online survey was offered to members of two German intensive care medicine societies.Measurements and main resultsIntensivists representing 390 German ICUs participated in this study (university hospitals 25%, tertiary hospitals 23%, secondary hospitals 36%, primary hospitals 16%). In 90% of participating ICUs, rounds were reported to take place in the morning and cover an average of 12 intensive care beds and 6 intermediate care beds within 60 min. With an estimated bed occupancy of 80%, this averaged to 4.3 min spent per patient during rounds. In 96% of ICUs, rounds were stated to include a bedside visit. On weekdays, 86% of the respondents reported holding a second ICU round with the attendance of a qualified decision-maker (e.g. board-certified intensivist). On weekends, 79% of the ICUs performed at least one round with a decision-maker per day. In 18%, only one ICU round per weekend was reported, mostly on Sundays. The highest-qualified decision-maker present during rounds on most ICUs was an ICU attending (57%). Residents (96%) and intensive care nurses (87%) were stated to be always or usually present during rounds. In contrast, physiotherapists, respiratory therapists or medical specialists such as pharmacists or microbiologist were not regular members of the rounding team on most ICUs. In the majority of cases, the participants reported examining the medical chart directly before or during the bedside visit (84%). An electronic patient data management system (PDMS) was available on 31% of ICUs. Daily goals were always (55%) or usually (39%) set during rounds.ConclusionThis survey gives a broad overview of the structure and processes of ICU rounds in different sized hospitals in Germany. Compared to other mostly Anglo-American studies, German ICU rounds appear to be shorter and less interdisciplinary.

Clinical characteristics of COVID-19 patients with clinically diagnosed bacterial co-infection: A multi-center study.

ObjectiveTo understand the clinical characteristics of COVID-19 patients with clinically diagnosed bacterial co-infection (CDBC), and therefore contributing to their early identification and prognosis estimation.Method905 COVID-19 patients from 7 different centers were enrolled. The demography data, clinical manifestations, laboratory results, and treatments were collected accordingly for further analyses.ResultsAround 9.5% of the enrolled COVID-19 patients were diagnosed with CDBC. Older patients or patients with cardiovascular comorbidities have increased CDBC probability. Increased body temperature, longer fever duration, anhelation, gastrointestinal symptoms, illness severity, intensive care unit attending, ventilation treatment, glucocorticoid therapy, longer hospitalization time are correlated to CDBC. Among laboratory results, increased white blood cell counting (mainly neutrophil), lymphocytopenia, increased procalcitonin, erythrocyte sedimentation rate, C-reaction protein, D-dimer, blood urea nitrogen, lactate dehydrogenase, brain natriuretic peptide, myoglobin, blood sugar and decreased albumin are also observed, indicating multiple system functional damage. Radiology results suggested ground glass opacity mixed with high density effusion opacities and even pleural effusion.ConclusionThe aged COVID-19 patients with increased inflammatory indicators, worse lymphopenia and cardiovascular comorbidities are more likely to have clinically diagnosed bacterial co-infection. Moreover, they tend to have severer clinical manifestations and increased probability of multiple system functional damage.

Improving racial disparities in unmet palliative care needs among intensive care unit family members with a needs-targeted app intervention: The ICUconnect randomized clinical trial

IntroductionThe technologies used to treat the millions who receive care in intensive care unit (ICUs) each year have steadily advanced. However, the quality of ICU-based communication has remained suboptimal, particularly concerning for Black patients and their family members. Therefore we developed a mobile app intervention for ICU clinicians and family members called ICUconnect that assists with delivering need-based care. ObjectiveTo describe the methods and early experiences of a clustered randomized clinical trial (RCT) being conducted to compare ICUconnect vs. usual care. Methods and analysisThe goal of this two-arm, parallel group clustered RCT is to determine the clinical impact of the ICUconnect intervention in improving outcomes overall and for each racial subgroup on reducing racial disparities in core palliative care outcomes over a 3-month follow up period. ICU attending physicians are randomized to either ICUconnect or usual care, with outcomes obtained from family members of ICU patients. The primary outcome is change in unmet palliative care needs measured by the NEST instrument between baseline and 3 days post-randomization. Secondary outcomes include goal concordance of care and interpersonal processes of care at 3 days post-randomization; length of stay; as well as symptoms of depression, anxiety, and post-traumatic stress disorder at 3 months post-randomization. We will use hierarchical linear models to compare outcomes between the ICUconnect and usual care arms within all participants and assess for differential intervention effects in Blacks and Whites by adding a patient-race interaction term. We hypothesize that both compared to usual care as well as among Blacks compared to Whites, ICUconnect will reduce unmet palliative care needs, psychological distress and healthcare resource utilization while improving goal concordance and interpersonal processes of care. In this manuscript, we also describe steps taken to adapt the ICUconnect intervention to the COVID-19 pandemic healthcare setting. Enrollment statusA total of 36 (90%) of 40 ICU physicians have been randomized and 83 (52%) of 160 patient-family dyads have been enrolled to date. Enrollment will continue until the end of 2021.

Impact of Patient Census and Admission Mortality on Pediatric Intensive Care Unit Attending Electronic Health Record Activity: A Preliminary Study.

Physicians may spend a significant amount of time using the electronic health record (EHR), but this is understudied in the pediatric intensive care unit (PICU). The objective of this study is to quantify PICU attending physician EHR usage and determine its association with patient census and mortality scores. During the year 2016, total EHR, chart review, and documentation times of 7 PICU physicians were collected retrospectively utilizing an EHR-embedded time tracking software package. We examined associations between documentation times and patient census and maximum admission mortality scores. Odds ratios (ORs) are reported per 1-unit increase in patient census and mortality scores. Overall, total daily EHR usage time (median time [hh:mm] [25th, 75th percentile]) was 2:10 (1:31, 3:08). For all hours (8 a.m.-8 a.m.), no strong association was noted between total EHR time, chart review, and documentation times and patient census, Pediatric Index of Mortality 2 (PIM2), or Pediatric Risk of Mortality 3 (PRISM3) scores. For regular hours (8 a.m.-7 p.m.), no strong association was noted between total EHR, chart review, and documentation times and patient census, PIM2, or PRISM3 scores. When patient census was higher, the odds of EHR after-hour usage (7 p.m.-8 a.m.) was higher (OR 1.262 [1.135, 1.403], p < 0.0001), but there were no increased odds with PIM2 (OR 1.090 [0.956, 1.242], p = 0.20) and PRISM3 (OR 1.010 [0.984, 1.036], p = 0.47) scores. A subset of physicians spent less time performing EHR-related tasks when patient census and admission mortality scores were elevated. We performed a novel evaluation of physician EHR workflow in our PICU. Our pediatric critical care physicians spend approximately 2 hours (out of an expected 10-hour shift) each service day using the EHR, but there was no strong or consistent association between EHR usage and patient census or mortality scores. Future larger scale studies are needed to ensure validity of these results.

Administrator Perspectives on ICU-to-Ward Transfers and Content Contained in Existing Transfer Tools: a Cross-sectional Survey.

The transfer of critically ill patients from the intensive care unit (ICU) to hospital ward is challenging. Shortcomings in the delivery of care for patients transferred from the ICU have been associated with higher healthcare costs and poor satisfaction with care. Little is known about how hospital ward providers, who accept care of these patients, perceive current transfer practices nor which aspects of transfer they perceive as needing improvement. To compare ICU and ward administrator perspectives regarding ICU-to-ward transfer practices and evaluate the content of transfer tools. Cross-sectional survey design. We administered a survey to 128 medical and/or surgical ICU and 256 ward administrators to obtain institutional perspectives on ICU transfer practices. We performed qualitative content analysis on ICU transfer tools received from respondents. In total, 108 (77%) ICU and 160 (63%) ward administrators responded to the survey. The ICU attending physician was reported to be "primarily responsible" for the safety (93% vs. 91%; p = 0.515) of patient transfers. ICU administrators more commonly perceived discharge summaries to be routinely included in patient transfers than ward administrators (81% vs. 60%; p = 0.006). Both groups identified information provided to patients/families, patient/family participation during transfer, and ICU-ward collaboration as opportunities for improvement. A minority of hospitals used ICU-to-ward transfer tools (11%) of which most (n = 21 unique) were designed to communicate patient information between providers (71%) and comprised six categories of information: demographics, patient clinical course, corrective aids, mobility at discharge, review of systems, and documentation of transfer procedures. ICU and ward administrators have similar perspectives of transfer practices and identified patient/family engagement and communication as priorities for improvement. Key information categories exist.

Impact of intensive care unit attending physician training background on outcomes in children undergoing heart operations

Background:The existing training pathways to become a pediatric cardiac intensivist are very variable with physicians coming from varied training backgrounds of pediatric critical care, pediatric cardiology, neonatology, or pediatric anesthesia.Aim:To evaluate the impact of cardiac Intensive Care Unit (ICU) attending physician training background on outcomes in children undergoing heart operations.Setting and Design:Patients in the age group from 1 day to 18 years undergoing heart operation at a Pediatric Health Information System database participating hospital were included (2010–2015).Patients and Methods:Based on the training background of majority of attending physicians in an ICU, the participating ICUs were divided into three groups: critical care medicine (CCM), cardiology, and indeterminate.Statistical Analysis:Multivariable logistic regression models were fitted to evaluate the association of ICU physician training background with study outcomes.Results:A total of 54,935 patients from 42 ICUs were included. Of these, 31,815 patients (58%) were treated in the CCM group (26 ICUs), 19,340 patients (35%) were treated in the cardiology group (12 ICUs), and 3780 patients (7%) were treated in the indeterminate group (4 ICUs). In adjusted models, no specific group based on ICU attending physician training background was associated with lower mortality (CCM vs. cardiology, odds ratio: 0.75, 95% confidence interval: 0.48–1.18), or lower incidence of cardiac arrest, or prolonged hospital length of stay, or prolonged mechanical ventilation.Conclusions:This large observational study did not demonstrate any impact of ICU attending training background on outcomes in children undergoing heart operations.

Enhanced antimicrobial de-escalation for pneumonia in mechanically ventilated patients: a cross-over study

BackgroundAntibiotics are commonly administered to hospitalized patients with infiltrates for possible bacterial pneumonia, often leading to unnecessary treatment and increasing the risk for resistance emergence. Therefore, we performed a study to determine if an enhanced antibiotic de-escalation practice could improve antibiotic utilization in mechanically ventilated patients with suspected pneumonia cared for in an academic closed intensive care unit (ICU).MethodsThis was a prospective cross-over trial comparing routine antibiotic management (RAM) and enhanced antimicrobial de-escalation (EAD) performed within two medical ICUs (total 34 beds) at Barnes-Jewish Hospital, an academic referral center. Patients in the EAD group had their antibiotic orders and microbiology results reviewed daily by a dedicated team comprised of a second-year critical care fellow, an ICU attending physician and an ICU pharmacist. Antibiotic de-escalation recommendations were made when appropriate based on microbiologic test results and clinical response to therapy.ResultsThere were 283 patients evaluable, with suspected pneumonia requiring mechanical ventilation: 139 (49.1%) patients in the RAM group and 144 (50.9%) in the EAD group. Early treatment failure based on clinical deterioration occurred in 33 (23.7%) and 40 (27.8%) patients, respectively (P = 0.438). In the remaining patients, antimicrobial de-escalation occurred in 70 (66.0%) and 70 (67.3%), respectively (P = 0.845). There was no difference between groups in total antibiotic days ((median (interquartile range)) 7.0 days (4.0, 9.0) versus 7.0 days (4.0, 8.8) (P = 0.616)); hospital mortality (25.2% versus 35.4% (P = 0.061)); or hospital duration (12.0 days (6.0, 20.0) versus 11.0 days (6.0, 22.0) (P = 0.918).ConclusionsThe addition of an EAD program to a high-intensity daytime staffing model already practicing a high-level of antibiotic stewardship in an academic ICU was not associated with greater antibiotic de-escalation or a reduction in the overall duration of antibiotic therapy.Trial registrationClinicalTrials.gov, NCT02685930.

Intensive Care Unit Educators: A Multicenter Evaluation of Behaviors Residents Value in Attending Physicians.

It is important for attending physicians to know which behaviors influence learner perceptions. To date, two studies focusing on general medicine attending physicians have been published addressing internal medicine residents' perceptions of attending physicians; there are no data on intensive care unit (ICU) attending physicians. We sought to expand the evidence regarding this topic through a multicenter study at four geographically diverse academic medical centers. Our study focused on identifying the teaching behaviors of ICU physicians that learners observe in attending physicians who they value as effective educators. The study was conducted at Indiana University (Indianapolis, IN), Johns Hopkins University (Baltimore, MD), University of California-San Francisco (San Francisco, CA), and University of Washington (Seattle, WA). Internal medicine residents completed an anonymous online survey rating the importance of behaviors of ICU attending physician role models. We created a 37-item questionnaire derived from prior studies and from the Clinician Teaching Program from the Stanford Faculty Development Center for Medical Teachers. This questionnaire included behaviors, current and past, that residents observed in their ICU attending physicians. A total of 260 of 605 residents responded to the survey (overall response rate of 43%). The five behaviors of attending physicians most commonly rated as "very important" to residents were: (1) enjoyment of teaching; (2) demonstrating empathy and compassion to patients and families; (3) ability to explain clinical reasoning and differential diagnoses; (4) treating nonphysician staff members respectfully; and (5) enthusiasm on rounds. Behaviors that trainees rated as less important were having numerous research publications, having served as chief resident, sharing personal life with residents, and organizing end-of-rotation social events. Our study provides new information to attending physicians striving to influence resident education. Although prior data demonstrated that learners valued attending physicians having served as chief resident and sharing personal information with learners, our study did not replicate this. We confirmed that learners appreciated teachers who are perceived to enjoy teaching. We discovered that behaviors, such as expression of empathy, explanation of clinical reasoning, and qualities of professionalism, were commonly seen in esteemed teaching attending physicians. Our study was limited by lack of correlation to objective performance metrics and a low response rate. Future work may include assessing the impact of faculty development on identified behaviors.

Association of 24/7 In-House Intensive Care Unit Attending Physician Coverage With Outcomes in Children Undergoing Heart Operations

Multicenter data regarding the around-the-clock (24/7) presence of an in-house critical care attending physician with outcomes in children undergoing cardiac operations are limited. Patients younger than 18 years of age who underwent operations (with or without cardiopulmonary bypass [CPB]) for congenital heart disease at 1 ofthe participating intensive care units (ICUs) in the Virtual PICU Systems (VPS, LLC) database were included (2009-2014). The study population was divided into 2 groups: the 24/7 group (14,737 patients; 32 hospitals), and the No 24/7 group (10,422 patients; 22 hospitals). Propensity-score matching was performed to match patients 1:1 in the 24/7 group and in the No 24/7 group. Overall, 25,159 patients from 54 hospitals qualified for inclusion. By propensity matching, 9,072 patients (4,536 patient pairs) from 51 hospitals were matched 1:1 in the 2 groups. After matching, mortality at ICU discharge was lower among the patients treated in hospitals with 24/7 coverage (24/7 versus No 24/7, 2.8% versus 4.0%; p= 0.002). The use of extracorporeal membrane oxygenation (ECMO), the incidence of cardiac arrest, extubation within 48 hours after operation, the rate of reintubation, and the duration of arterial line and central venous line use after operation were significantly improved in the 24/7 group. When stratified by surgical complexity, survival benefits of 24/7 coverage persisted among patients undergoing both high-complexity and low-complexity operations. The presence of 24-hour in-ICU attending physician coverage in children undergoing cardiac operations is associated with improved outcomes, including ICU mortality. It is possible that 24-hour in-ICU attending physician coverage may be a surrogate for other factors that may bias the results. Further study is warranted.

Deception and Death in Medical Simulation

Medical simulation requires, by definition, a certain degree of “make believe.” The mannequin is not a real person, the scenario is not really happening, and no patients are either helped or harmed. Successful education in the simulated setting depends on skilled facilitators who can effectively per

Correlating data from different sensors to increase the positive predictive value of alarms: an empiric assessment

Objectives: Alarm fatigue from high false alarm rate is a well described phenomenon in the intensive care unit (ICU). Progress to further reduce false alarms must employ a new strategy. Highly sensitive alarms invariably have a very high false alarm rate. Clinically useful alarms have a high Positive-Predictive Value. Our goal is to demonstrate one approach to suppressing false alarms using an algorithm that correlates information across sensors and replicates the ways that human evaluators discriminate artifact from real signal. Methods: After obtaining IRB approval and waiver of informed consent, a set of definitions, (hypovolemia, left ventricular shock, tamponade, hemodynamically significant ventricular tachycardia, and hemodynamically significant supraventricular tachycardia), were installed in the monitors in a 10 bed cardiothoracic ICU and evaluated over an 85 day study period. The logic of the algorithms was intended to replicate the logic of practitioners, and correlated information across sensors in a way similar to that used by practitioners. The performance of the alarms was evaluated via a daily interview with the ICU attending and review of the tracings recorded over the previous 24 hours in the monitor. True alarms and false alarms were identified by an expert clinician, and the performance of the algorithms evaluated using the standard definitions of sensitivity, specificity, positive predictive value, and negative predictive value. Results: Between 1 and 221 instances of defined events occurred over the duration of the study, and the positive predictive value of the definitions varied between 4.1% and 84%. Conclusions: Correlation of information across alarms can suppress artifact, increase the positive predictive value of alarms, and can employ more sophisticated definitions of alarm events than present single-sensor based systems.

Barriers to End-of-Life Care in the Intensive Care Unit: Perceptions Vary by Level of Training, Discipline, and Institution

Barriers to providing quality end-of-life (EOL) care in the intensive care unit (ICU) are common, but little is known about how these barriers vary by level of training or discipline. Medical residents and ICU fellows, attendings, and nurses at two teaching hospitals were surveyed about barriers to EOL care in the ICU. The survey consisted of questions about possible barriers in four domains: patient-family factors, clinician factors, institutional factors, and education-training factors. There were significant differences in reported barriers to EOL care by level of training, discipline, and institution, particularly in the education-training domain. Insufficient resident training in EOL care was reported as a large or huge barrier by a smaller proportion of residents (20%) than attendings (62%), fellows (55%) or nurses (36%) (p=0.001). Nurses' perceptions of barriers to EOL care varied between institutions. Barriers that varied significantly between nurses included difficulty communicating due to language (p=0.008), and inadequate training in recognition of pain and anxiety (p=0.001). We found that perceived barriers to EOL care differed significantly by level of training, discipline and institution, suggesting the interventions to improve EOL care may need to be locally targeted and specific to level of training and discipline.
