Assessing an Exposure Keratopathy Prevention Strategy in Mechanically Ventilated Patients: A Retrospective Study.

OBJECTIVE: Patients who are intubated and sedated are at risk for developing exposure keratopathy, which can lead to permanent vision loss. This retrospective study assesses the incidence of exposure keratopathy (EK) in intensive care unit (ICU) patients before and after implementation of an EK Prevention Order Set. METHODS: At one tertiary care hospital (Bronx, NY), an "Exposure Keratopathy Prevention Order Set" was implemented to ameliorate this risk which included the application of white petrolatum-mineral oil lubricating ointment every 6 hours in both eyes. This retrospective chart review study analyzed the incidence of EK diagnosis before and after implementation of this EK Prevention Order Set. Patients who were on mechanical ventilation at the time of ophthalmology consult request between January 1, 2021, and December 31, 2021, were included. Ophthalmology consult notes of patients with EK diagnosis were reviewed for details regarding the consult request, examination findings, diagnosis, and treatment plan. RESULTS: There were 247 and 361 ventilated ICU patients before and after the order set, respectively. The number of ophthalmology consults decreased slightly after the order set from 15 of 247 to 20 of 361 ventilated patients. In addition, the rate of EK among ventilated patients decreased from 4.5% (11 of 247 patients over 151 days) to 2.2% (8 of 361 patients over 212 days; P =0.154) with a risk ratio of 0.50 (95% CI 0.20-1.22). CONCLUSION: The number of patients diagnosed with EK trended down after implementation of the EK Prevention Order Set.

Obesity is Unlikely to be an Impediment to First-Pass Success During the Intubation of Critically Ill Patients.

Background: Obesity has been described as a potential risk factor for difficult intubation among critically ill patients. Our primary aim was to further elucidate the association between obesity and first-pass success. Our secondary aim was to determine whether the use of hyper-angulated video laryngoscopy improves first-pass success compared to direct laryngoscopy when utilized for the intubation of critically ill obese patients. Study Design and Methods: A retrospective cohort study of adult patients undergoing endotracheal intubation outside of the operating room or emergency department between January 30, 2016 and May 1, 2020 at 3 campuses of an academic hospital system in the Bronx, NY. Our primary outcome was first-pass success of intubation. A multivariate logistic analysis was utilized to compare obesity status with first-pass success. Results: We identified 3791 critically ill patients who underwent endotracheal intubation of which 1417 were obese (body mass index [BMI] ≥ 30). The incidence of hyper-angulated video laryngoscopy increased over the study period. A total of 46.6% of obese patients underwent intubation with hyper-angulated video laryngoscopy as compared to 35.1% of the nonobese group. First-pass success was 79.2% among the entire cohort. Obesity status did not appear to be associated with first-pass success (adjusted odds ratio [OR] 1.07, 95% confidence interval [CI]: 090-1.27; P = .47). Hyper-angulated video laryngoscopy did not seem to improve first-pass success among obese patients as compared to nonobese patients (adjusted OR 1.21, 95% CI: 0.85-1.71; P = .29). These findings persisted even after redefining the obesity cutoff as BMI ≥ 40 and excluding patients intubated during cardiac arrests. Conclusion: We did not detect an association between obesity and first-pass success. Hyper-angulated video laryngoscopy did not appear offer additional benefit over direct laryngoscopy during the intubation of critically ill obese patients.

Critical Care Surge During the COVID-19 Pandemic: Implementation and Feedback From Frontline Providers.

PURPOSE: Montefiore Medical Center (MMC) in the Bronx, New York, was subjected to an unprecedented surge of critically ill patients with COVID-19 disease during the initial outbreak of the pandemic in New York State in the spring of 2020. It is important to describe our experience in order to assist hospitals in other areas of the country that may soon be subjected to similar surges. MATERIALS AND METHODS: We retrospectively reviewed the expansion of critical care medicine services at Montefiore during the COVID-19 surge in terms of space, staff, stuff, and systems. In addition, we report on a debriefing session held with a multidisciplinary group of frontline CCM providers at Montefiore. FINDINGS: The surge of critically ill patients from COVID-19 disease necessitated a tripling of critical care bed capacity at (MMC), with attendant increased needs for staffing, equipment, and systematic innovations to increase efficiency and effectiveness. Feedback from a multidisciplinary group of frontline providers revealed multiple opportunities for improvement for the next potential surge at MMC as well as guidance for other hospitals. CONCLUSIONS: Given increasing cases and burden of critical illness from COVID-19 across the US, engineering safe and effective expansions of critical care capacity will be crucial. We hope that our description of what worked and what did not at MMC will help guide other hospitals in their pandemic preparedness.

Impact of a Critical Care Specialist Intervention on First Pass Success for Emergency Airway Management Outside the ICU.

BACKGROUND: There has been limited investigation into the procedural outcomes of patients undergoing emergent endotracheal intubation (EEI) by a critical care medicine (CCM) specialist outside the intensive care unit (ICU). We hypothesized that EEI outside an ICU would be associated with lower rates of first pass success (FPS) as compared to inside an ICU. METHODS: We performed a retrospective cohort study of all adult patients admitted to our academic medical center between January 1, 2016, and July 31, 2018, who underwent EEI by a CCM practitioner. The primary outcome of FPS was identified in the EEI procedure note. Secondary outcomes included difficult intubation (> 2 attempts at laryngoscopy) and mortality following EEI. RESULTS: In total, 1958 patients (1035 [52.9%] inside ICU and 923 [47.1%]) outside an ICU) were included in the final cohort. Unadjusted rate of FPS was not different between patients intubated out of the ICU and patients intubated inside of the ICU (689 [74.7%] vs 775 [74.9%]; P = .91). There was also no difference in FPS between groups after adjusting for predictors of difficult intubation and baseline covariates (odds ratio: 0.95; 95% confidence interval, 0.75-1.2, P = .65). Mortality of patients undergoing EEI out of the ICU was higher at each examined time interval following EEI. DISCUSSION: For EEI done by CCM practitioners, rate of FPS is not different between patients undergoing EEI outside an ICU as compared to inside an ICU. Despite the lack of difference between rates of procedural success, patient mortality following EEI outside an ICU is higher than EEI inside an ICU at all examined time points during hospitalization.

The Impact of Nighttime on First Pass Success During the Emergent Endotracheal Intubation of Critically Ill Patients.

BACKGROUND: While numerous investigations have described worse outcomes for patients undergoing emergent procedures at night, few studies have investigated the impact of nighttime on the outcomes of emergent endotracheal intubation (EEI). We hypothesized that for patients requiring EEI at night, the outcome of first pass success would be lower as compared to during the day. METHODS: We performed a retrospective cohort study of all patients admitted to our institution between January 1st, 2016 and July 17st, 2019 who underwent EEI outside of an emergency department or operating room. Nighttime was defined as between 7:00 pm and 6:59 am. The primary outcome was the rate of first pass success. Logistic regression was utilized with adjustment for demographic, morbidity and procedure related covariables. RESULTS: The final examined cohort included 1,674 EEI during the day and 1,229 EEI at night. The unadjusted rate of first pass success was not different between the day and night (77.5% vs. 74.6%, unadjusted odds ratio (OR): 0.85; 95% confidence interval (CI): 0.72, 1.0; P = 0.073 though following adjustment for prespecified covariables the odds of first pass success was lower at night (adjusted OR: 0.83, 95% CI: 0.69, 0.99; P = 0.042. Obesity was found to be an effect modifier on first pass success rate for day vs. night intubations. In obese patients, nighttime intubations had significantly lower odds of first pass success (adjusted OR: 0.71, 95% CI: 0.52, 0.98; P = 0.037). DISCUSSION: After adjustment for patient and procedure related factors, we have found that the odds of first pass success is lower at night as compared to the day. This finding was, to some degree, driven by obesity which was found to be a significant effect modifier in this relationship.

A Regional, Cost-Effective, Collaborative Model for Critical Care Fellows' Ultrasonography Education.

OBJECTIVE: Training in critical care ultrasonography is an essential tool in critical care medicine and recommended for fellowship programs in pulmonary and critical care medicine. Major barriers to implementing competency-based training in individual fellowship programs include a lack of expert faculty, time, and funding. Our objective was to investigate whether regional collaboration to deliver an introductory critical care ultrasonography course for fellows might overcome these barriers while achieving international training standards. METHODS: This was a retrospective review of course evaluation and learner assessment data from a 3-day ultrasonography course between 2012 and 2017. All critical care fellows (n = 545) attending the course completed pre- and postcourse surveys and postcourse knowledge and technical skills tests. Evaluation of educational outcomes was performed based on the Kirkpatrick model. RESULTS: Fellows reported minimal prior formal training in ultrasonography, and ultrasound-guided vascular access was the most common area of prior training. The course was a blended model of didactic lectures coordinated with real-time demonstration scanning using live models, hands-on training on human models and task trainers, and interpretation of ultrasonography images with a wide range of pathology. Course content included basic echocardiography and general critical care ultrasonography (lung, pleural, vascular diagnostic, vascular access, and abdominal ultrasonography). At the conclusion of the course, fellows demonstrated high levels of knowledge and skill competence on a previously validated assessment tool and significantly improved confidence in all content areas. Barriers to training at individual programs were overcome through faculty cooperation, faculty development, and cost sharing. Success of this model is supported by the sustained growth of this course. CONCLUSIONS: A regional collaborative model for training fellows in ultrasonography is a feasible, efficient, and flexible model for delivering curricula, where expertise at individual programs is not routinely available.

Lung Ultrasound for the Diagnosis and Management of Acute Respiratory Failure.

For critically ill patients with acute respiratory failure (ARF), lung ultrasound (LUS) has emerged as an indispensable tool to facilitate diagnosis and rapid therapeutic management. In ARF, there is now evidence to support the use of LUS to diagnose pneumothorax, acute respiratory distress syndrome, cardiogenic pulmonary edema, pneumonia, and acute pulmonary embolism. In addition, the utility of LUS has expanded in recent years to aid in the ongoing management of critically ill patients with ARF, providing guidance in volume status and fluid administration, titration of positive end-expiratory pressure, and ventilator liberation. The aims of this review are to examine the basic foundational concepts regarding the performance and interpretation of LUS, and to appraise the current literature supporting the use of this technique in the diagnosis and continued management of patients with ARF.

The Diagnostic and Therapeutic Impact of Point-of-Care Ultrasonography in the Intensive Care Unit.

PURPOSE: In light of point-of-care ultrasonography's (POCUS) recent rise in popularity, assessment of its impact on diagnosis and treatment in the intensive care unit (ICU) is of key importance. METHODS: Ultrasound examinations were collected through an ultrasound reporting software in 6 multidisciplinary ICU units from 3 university hospitals in Canada and the United States. This database included a self-reporting questionnaire to assess the impact of the ultrasound findings on diagnosis and treatment. We retrieved the results of these questionnaires and analyzed them in relation to which organs were assessed during the ultrasound examination. RESULTS: One thousand two hundred and fifteen ultrasound studies were performed on 968 patients. Intensivists considered the image quality of cardiac ultrasound to be adequate in 94.7% compared to 99.7% for general ultrasound ( P < .001). The median duration of a cardiac examination was 10 (interquartile range [IQR] 10) minutes compared to 5 (IQR 8) minutes for a general examination ( P < .001). Overall, ultrasound findings led to a change in diagnosis in 302 studies (24.9%) and to a change in management in 534 studies (44.0%). A change in diagnosis or management was reported more frequently for cardiac ultrasound than for general ultrasound (108 [37.1%] vs 127 [16.5%], P < .001) and (170 [58.4%] vs 270 [35.1%], P < .001). Assessment of the inferior vena cava for fluid status emerged as the critical care ultrasound application associated with the greatest impact on management. CONCLUSION: Point-of-care ultrasonography has the potential to optimize care of the critically ill patients when added to the clinical armamentarium of the intensive care physician.

A Time-Motion Study of ICU Workflow and the Impact of Strain.

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

Daytime Versus Nighttime Extubations: A Comparison of Reintubation, Length of Stay, and Mortality.

PURPOSE: Despite studies regarding outcomes of day versus night medical care, consequences of nighttime extubations are unknown. It may be favorable to extubate patients off-hours, as soon as weaning parameters are met, since this could decrease complications and shorten length of stay (LOS). Conversely, nighttime extubation could be deleterious, as staffing varies during this time. We hypothesized that patients have similar reintubation rates, irrespective of extubation time. METHODS: A retrospective cohort study performed at 2 hospitals within a tertiary academic medical center included all adult intensive care unit (ICU) patients extubated between July 01, 2009 and May 31, 2011. Those extubated due to withdrawal of support were excluded. The nighttime group included patients extubated between 7:00 pm and 6:59 am and the daytime group included patients extubated between 7:00 am and 6:59 pm. RESULTS: Of 2240 extubated patients, 1555 were extubated during the day and 685 were extubated at night. Of these, 119 (7.7%) and 26 (3.8%), respectively, were reintubated in 24 hours with likelihood of reintubation significantly lower for nighttime than daytime after multivariable adjustment (odds ratio [OR] = 0.5, 95% confidence interval [CI] 0.3-0.9, P = .01), with a similar trend for reintubation within 72 hours (OR = 0.7, 95% CI = 0.5-1.0, P = .07). There was a trend toward decreased mortality for patients extubated at night (OR = 0.6, 95% CI = 0.3-1.0, P = .06). There was also a significantly lower LOS for patients extubated at night (P = .002). In a confirmatory frequency-matched analysis, there was no significant difference in reintubation proportion or mortality, but LOS was significantly less in those extubated at night. CONCLUSIONS: Intensive care unit extubations at night did not have higher likelihood of reintubation, LOS, or mortality compared to those during the day. Since patients should be extubated as soon as they meet parameters in order to potentially decrease complications of mechanical ventilation, these data provide no support for delaying extubation until daytime.

Improving the Patient Handoff Process in the Intensive Care Unit: Keys to Reducing Errors and Improving Outcomes.

Patient handoffs are highly variable and error prone. They have been recognized as a major health care challenge. Patients in the intensive care unit are particularly vulnerable due to their complex clinical history and the critical nature of their condition. Given a general movement from traditional long call to shift schedules, the number of patient handoffs will likely continue to increase. Optimization of the handoff process has become even more critical to ensure patient safety. In this review, we reflect on the importance of the handoff process, review common errors, identify barriers and challenges, and propose different methods to improving the handoff process. The purpose of this article is to examine the overall scope of the problem; provide the most up-to-date evidence on the handoff process; and identify ways to perform handoffs in an accurate, safe, and efficient manner to provide high-quality patient care. The direction of future research is also proposed.

Design and implementation of the hospital airway resuscitation trial.

Guidelines for the management of in-hospital cardiac arrest resuscitation are often drawn from evidence generated in out-of-hospital cardiac arrest populations and applied to the in-hospital setting. Approach to airway management during resuscitation is one example of this phenomenon, with the recommendation to place either a supraglottic airway or endotracheal tube when performing advanced airway management during in-hospital cardiac arrest based mainly in clinical trials conducted in the out-of-hospital setting. The Hospital Airway Resuscitation Trial (HART) is a pragmatic cluster-randomized superiority trial comparing a strategy of first choice supraglottic airway to a strategy of first choice endotracheal intubation during resuscitation from in-hospital cardiac arrest. The design includes a number of innovative elements such as a highly pragmatic design drawing from electronic health records and a novel primary outcome measure for cardiac arrest trials-alive-and-ventilator free days. Many of the topics explored in the design of HART have wide relevance to other trials in in-hospital cardiac arrest populations.

Online testing from Google Docs™ to enhance teaching of core topics in critical care: a pilot study.

BACKGROUND: Recent evidence suggests that retrieval practice, or learning by testing, may lead to more effective knowledge retention than standard educational techniques. AIM: The purpose of this pilot project was to document successful teaching of evidence-based guidelines in critical care by augmenting interactive problem-based teaching sessions with online pre- and post-testing. METHODS: We used a free, internet-based document collaboration system (Google Docs™) 1 to develop and share pre-tests and pre-session teaching files with the fellows. At the teaching sessions the pre-tests were reviewed interactively, and additional case-based questions were presented. One week after the sessions, the fellows were sent a post-test and a post-session survey. Results of the pre- and post-tests as well as the post-session surveys were tabulated by the document collaboration system. RESULTS: The mean score was 54.6% (SD = 21.4%) on the pre-tests and 87.0% (SD = 15.8%) on the post-tests (p < 0.01). On a scale of 1-10, the median ratings given by the fellows were 9.5 (IQR = 9-10) for utility of the teaching sessions, 9 for utility of the test questions (IQR = 9-10), and 10 (IQR = 9-10) for utility of the teaching files. CONCLUSION: Google Docs™ can be successfully used to integrate retrieval practice into the teaching of evidence-based guidelines in critical care.

Critical Care Response During the COVID-19 Pandemic.

Hospitals and health care systems with active critical care organizations (CCOs) that unified ICU units before the onset of the COVID-19 Pandemic were better positioned to adapt to the demands of the pandemic, due to their established standardization of care and integration of critical care within the larger structure of the hospital or health care system. CCOs should continue to make changes, based on the real experience of COVID-19 that would lead to improved care during the ongoing pandemic, and beyond.

Improved performance of maternal-fetal medicine staff after maternal cardiac arrest simulation-based training.

OBJECTIVE: To determine the impact of simulation-based maternal cardiac arrest training on performance, knowledge, and confidence among Maternal-Fetal Medicine staff. STUDY DESIGN: Maternal-Fetal Medicine staff (n = 19) participated in a maternal arrest simulation program. Based on evaluation of performance during initial simulations, an intervention was designed including: basic life support course, advanced cardiac life support pregnancy modification lecture, and simulation practice. Postintervention evaluative simulations were performed. All simulations included a knowledge test, confidence survey, and debriefing. A checklist with 9 pregnancy modification (maternal) and 16 critical care (25 total) tasks was used for scoring. RESULTS: Postintervention scores reflected statistically significant improvement. Maternal-Fetal Medicine staff demonstrated statistically significant improvement in timely initiation of cardiopulmonary resuscitation (120 vs 32 seconds, P = .042) and cesarean delivery (240 vs 159 seconds, P = .017). CONCLUSION: Prompt cardiopulmonary resuscitation initiation and pregnancy modifications application are critical in maternal and fetal survival during cardiac arrest. Simulation is a useful tool for Maternal-Fetal Medicine staff to improve skills, knowledge, and confidence in the management of this catastrophic event.

A program to improve the quality of emergency endotracheal intubation.

OBJECTIVE: To assess the results of a quality improvement (QI) project designed to improve safety of emergency endotracheal intubation (EEI). DESIGN: Single center prospective observational. SETTING: 16-bed intensive care unit. PARTICIPANTS: Nine pulmonary/critical care fellows. INTERVENTIONS: For 3 years, EEI performed by the medical intensive care unit team were analyzed to identify interventions that would improve quality of the procedure. By segmental process analysis, the procedure of EEI was subjected to iterative change. Major components of process improvement were development of a combined team approach, a mandatory checklist, use of crew resource management (CRM) tactics, and postevent debriefing. Quality analysis and improvement included training of fellows using scenario-based training (SBT) with computerized patient simulator (CPS) to improve mechanical skills of intubation and team leadership. Fellows received 15 sessions of SBT with CPS using a combined checklist and team approach before assuming team leadership position during real-life EEI. MEASUREMENTS: For a 10-month period, fellows carried digital voice recorders to EEI; which, when combined with recording of continuous oximetry and BP monitoring were used to assess the quality of EEI. MAIN RESULTS: 128 EEI were performed of which 101 had full data recorded. Complications were 14% severe hypoxemia (<80% saturation), 6% severe hypotension (SBP<70 mm Hg), 1% death, 20% difficult EEI (≥ 3 attempts), 11% esophageal intubations, 2% aspiration, and 1% dental injury; 62% EEI were successfully achieved on first attempt, 11% required >3 attempts. CONCLUSIONS: EEI may be performed by pulmonary/critical medicine (PCCM) fellows with safety comparable to that described in other studies on EEI. Important parts of the program included the use of formal iterative QI approach, the use of intensive SBT with CPS, basic CRM, a comprehensive checklist, and a combined team approach. A key benefit of the program was to make the process of EEI fully transparent for ongoing quality and safety improvement.

Non-invasive methods of estimating intracranial pressure.

Non-invasive measurement of intracranial pressure can be invaluable in the management of critically ill patients. We performed a comprehensive review of the literature to evaluate the different methods of measuring intracranial pressure. Several methods have been employed to estimate intracranial pressure, including computed tomography, magnetic resonance imaging, transcranial Doppler sonography, near-infrared spectroscopy, and visual-evoked potentials. In addition, multiple techniques of measuring the optic nerve and the optic nerve sheath diameter have been studied. Ultrasound measurements of the optic nerve sheath diameter and Doppler flow are especially promising and may be useful in selected settings.

Practice, Outcomes, and Complications of Emergent Endotracheal Intubation by Critical Care Practitioners During the COVID-19 Pandemic.

BACKGROUND: For patients with COVID-19 who undergo emergency endotracheal intubation, data are limited regarding the practice, outcomes, and complications of this procedure. RESEARCH QUESTION: For patients with COVID-19 requiring emergency endotracheal intubation, how do the procedural techniques, the incidence of first-pass success, and the complications associated with the procedure compare with intubations of critically ill patients before the COVID-19 pandemic? STUDY DESIGN AND METHODS: We conducted a retrospective study of adult patients with COVID-19 at Montefiore Medical Center who underwent first-time endotracheal intubation by critical care physicians between July 19, 2019, and May 1, 2020. The first COVID-19 patient was admitted to our institution on March 11, 2020; patients admitted before this date are designated the prepandemic cohort. Descriptive statistics were used to compare groups. A Fisher exact test was used to compare categorical variables. For continuous variables, a two-tailed Student t test was used for parametric variables or a Wilcoxon rank-sum test was used for nonparametric variables. RESULTS: One thousand two hundred sixty intubations met inclusion criteria (782 prepandemic cohort, 478 pandemic cohort). Patients during the pandemic were more likely to be intubated for hypoxemic respiratory failure (72.6% vs 28.1%; P < .01). During the pandemic, operators were more likely to use video laryngoscopy (89.4% vs 53.3%; P < .01) and neuromuscular blocking agents (86.0% vs 46.2%; P < .01). First-pass success was higher during the pandemic period (94.6% vs 82.9%; P < .01). The rate of associated complications was higher during the pandemic (29.5% vs 15.2%; P < .01), a finding driven by a higher rate of hypoxemia during or immediately after the procedure (25.7% vs 8.2%; P < .01). INTERPRETATION: Video laryngoscopy and neuromuscular blockade were used increasingly during the COVID-19 pandemic. Despite a higher rate of first-pass success during the pandemic, the incidence of complications associated with the procedure was higher.

The Effect of Numbered Jerseys on Directed Commands, Teamwork, and Clinical Performance During Simulated Emergencies.

ABSTRACT: Communication and teamwork are essential during inpatient emergencies such as cardiac arrest and rapid response (RR) codes. We investigated whether wearing numbered jerseys affect directed commands, teamwork, and performance during simulated codes. Eight teams of 6 residents participated in 64 simulations. Four teams were randomized to the experimental group wearing numbered jerseys, and four to the control group wearing work attire. The experimental group used more directed commands (49% vs. 31%, p < .001) and had higher teamwork score (25 vs. 18, p < .001) compared with control group. There was no difference in time to initiation of chest compression, bag-valve-mask ventilation, and correct medications. Time to defibrillation was longer in the experimental group (190 vs. 140 seconds, p = .035). Using numbered jerseys during simulations was associated with increased use of directed commands and better teamwork. Time to performance of clinical actions was similar except for longer time to defibrillation in the jersey group.

Barriers to ultrasound training in critical care medicine fellowships: a survey of program directors.

OBJECTIVE: Ultrasonography is an effective tool for making quick diagnoses and guiding therapeutic procedures. National organizations have advocated increasing the use of critical care ultrasonography. The purpose of this study was to investigate the prevalence of teaching of critical care ultrasonography in fellowship programs. In addition, we hoped to identify barriers to establishment of ultrasound training programs. DESIGN: All pulmonary/critical care and critical care medicine (CCM) program directors in the United States were invited to participate in an online survey. We asked respondents for demographic information about their programs and perceived barriers to training, as well as current training opportunities for their fellows in five aspects of critical care ultrasonography. A five-point Likert scale was used for survey answers. SETTING: Web-based survey. SUBJECTS: Pulmonary/critical care and CCM program directors in the United States. INTERVENTIONS: Web-based survey. MEASUREMENTS AND MAIN RESULTS: Ninety (66%) of 136 program directors responded. Ultrasonography training was offered by fellowship programs in the following areas: vascular access (98%), lung and pleural (74%), cardiac (55%), vascular diagnostic (33%), and abdominal (37%). Ninety-two percent of respondents agreed or strongly agreed that ultrasound training is useful, and 80% were interested in getting their fellows trained. Forty-one percent indicated that they lacked sufficient faculty trained in ultrasound use. Eighty-four percent agreed or strongly agreed that fellow turnover was an impediment to training. Forty-eight percent believed that cardiac echocardiography required a long training time. CONCLUSIONS: Although ultrasound training in vascular access was nearly universal, training in other aspects of ultrasound was less prevalent. We identified several barriers, including fellow turnover, insufficient faculty training, and perceived length of time required for echocardiography training.
