Transfer Patient Imaging: Assessment of the Impact of Discrepancies Identified by Emergency Radiologists.

PURPOSE: Advanced imaging examinations of emergently transferred patients (ETPs) are overread to various degrees by receiving institutions. The practical clinical impact of these second opinions has not been studied in the past. The purpose of this study is to determine if emergency radiology overreads change emergency medicine decision making on ETPs in the emergency department (ED). METHODS: All CT and MRI examinations on patients transferred to a level I trauma center during calendar year 2018 were routinely overread by emergency radiologists and discrepancies with the outside report electronically flagged. All discrepant reports compared with the outside interpretations were reviewed by one of four emergency medicine physicians. Comparing the original and final reports, reviewers identified changes in patient management that could be attributed to the additional information contained in the final report. Changes in patient care were categorized as affecting ED management, disposition, follow-up, or consulting services. RESULTS: Over a 12-month period, 5,834 patients were accepted in transfer. Among 5,631 CT or MRI examinations with outside reports available, 669 examinations (12%) had at least one discrepancy in the corresponding outside report. In 219 examinations (33%), ED management was changed by discrepancies noted on the final report; patient disposition was affected in 84 (13%), outpatient follow-up in 54 (8%), and selection of consulting services in 411 (61%), and ED stay was extended in 544 (81%). Discrepant findings affected decision making in 613 of 669 of examinations (92%). CONCLUSION: Emergency radiology overreading of transferred patients' advanced imaging examinations provided actionable additional information to emergency medicine physicians in the care of 613 of 669 (92%) examinations with discrepant findings. This added value is worth the effort to design workflows to routinely overread CT and MRI examinations of ETPs.

Western Washington State COVID-19 Experience: Keys to Flattening the Curve and Effective Health System Response.

BACKGROUND: Washington State experienced the first major outbreak of COVID-19 in the US and despite a significant number of cases, has seen a relatively low death rate per million population compared with other states with major outbreaks, and has seen a substantial decrease in the projections for healthcare use, that is, "flattening the curve." This consensus report seeks to identify the key factors contributing to the effective health system disaster response in western WA. METHODS: A multidisciplinary, expert panel including individuals and organizations who were integral to managing the public health and emergency healthcare system response were engaged in a consensus process to identify the key themes and lessons learned and develop recommendations for ongoing management of the COVID-19 pandemic. RESULTS: Six key themes were identified, including early communication and coordination among stakeholders; regional coordination of the healthcare system response; rapid development and access to viral testing; proactive management of long-term care and skilled nursing facilities; proactive management of vulnerable populations; and effective physical distancing in the community. CONCLUSIONS: Based on the lessons learned in each of the areas identified by the panel, 11 recommendations are provided to support the healthcare system disaster response in managing future outbreaks.

Improving emergency department blood product use through nursing education.

BACKGROUND: Rapid access to blood products can be lifesaving for hemorrhaging patients, but placing blood components in easily accessible locations in the emergency department (ED) can lead to wasteful patterns of use. Education can lead to improvements in transfusion behavior, but such changes for the better are often short lived. METHODS: To facilitate the early initiation of balanced resuscitation, an emergency blood refrigerator was placed in our ED in February 2015. Physician education to give blood components in a 1:1 plasma:red blood cell (RBC) unit ratio with the plasma given first was given repeatedly with short-term success. Finally, nurses were trained and empowered to strongly suggest that blood components be given in balanced ratios and that plasma be given first. Plasma:RBC unit ratios were compared in successive years with the chi-square test for trend. RESULTS: A total of 1165 RBC units and 623 plasma units were issued from the ED emergency blood refrigerator over 5 years. Intensive physician education is documented at start, in late 2016 to early 2017, and again in early and late 2018. Ratios of components (U plasma/U RBCs) were 2015, 17%; 2016, 26%; 2017, 61%; 2018, 49%; and 2019, 91% (p < 10-18 chi-square for trend). Higher ratios of plasma use were associated with $40,000+ annual savings. CONCLUSIONS: Giving the ED senior nurses formal education about the need for and a policy to give guidance on massive transfusion protocol (MTP) blood component administration sequence has achieved compliance with our MTP's intention. Increasing plasma use reduces group O RBC use and total blood costs.

Trauma Providers' Perceptions of Frailty Assessment: A Mixed-Methods Analysis of Knowledge, Attitudes, and Beliefs.

OBJECTIVES: Quality improvement in geriatric trauma depends on timely identification of frailty, yet little is known about providers' knowledge and beliefs about frailty assessment. This study sought to understand trauma providers' understanding, beliefs, and practices for frailty assessment. METHODS: We developed a 20-question survey using the Health Belief Model of health behavior and surveyed physicians, advanced practice providers, and trainees on the trauma services at a single institution that does not use formal frailty screening of all injured seniors. Results were analyzed via mixed methods. RESULTS: One hundred fifty-one providers completed the survey (response rate 92%). Respondents commonly included calendar age as an integral factor in their determinations of frailty but also included a variety of other factors, highlighting limited definitional consensus. Respondents perceived frailty as important to older adult patient outcomes, but assessment techniques were varied because only 24/151 respondents (16%) were familiar with current formal frailty assessment tools. Perceived barriers to performing a formal frailty screening on all injured older adults included the burdensome nature of assessment tools, insufficient training, and lack of time. When prompted for solutions, 20% of respondents recommended automation of the screening process by trained, dedicated team members. CONCLUSIONS: Providers seem to recognize the impact that a diagnosis of frailty has on outcomes, but most lack a working knowledge of how to assess for frailty syndrome. Some providers recommended screening by designated, formally trained personnel who could notify decision makers of a positive screen result.

Association of Radiologic Indicators of Frailty With 1-Year Mortality in Older Trauma Patients: Opportunistic Screening for Sarcopenia and Osteopenia.

Importance: Assessment of physical frailty in older trauma patients admitted to the intensive care unit is often not feasible using traditional frailty assessment instruments. The use of opportunistic computed tomography (CT) scans to assess sarcopenia and osteopenia as indicators of underlying frailty may provide complementary prognostic information on long-term outcomes. Objective: To determine whether sarcopenia and/or osteopenia are associated with 1-year mortality in an older trauma patient population. Design, Setting, and Participants: A retrospective cohort constructed from a state trauma registry was linked to the statewide death registry and Comprehensive Hospital Abstract Reporting System for readmission data analyses. Admission abdominopelvic CT scans from patients 65 years and older admitted to the intensive care unit of a single level I trauma center between January 2011 and May 2014 were analyzed to identify patients with sarcopenia and/or osteopenia. Patients with a head Injury Severity Score of 3 or greater, an out-of-state address, or inadequate CT imaging or who died within 24 hours of admission were excluded. Exposures: Sarcopenia and/or osteopenia, assessed via total cross-sectional muscle area and bone density at the L3 vertebral level, compared with a group with no sarcopenia or osteopenia. Main Outcomes and Measures: One-year all-cause mortality. Secondary outcomes included 30-day all-cause mortality, 30-day readmission, hospital length of stay, hospital cost, and discharge disposition. Results: Of the 450 patients included in the study, 269 (59.8%) were male and 394 (87.6%) were white. The cohort was split into 4 groups: 74 were retrospectively diagnosed with both sarcopenia and osteopenia, 167 with sarcopenia only, 48 with osteopenia only, and 161 with no radiologic indicators. Among the 408 who survived to discharge, sarcopenia and osteopenia were associated with higher risks of 1-year mortality alone and in combination. After adjustment, the hazard ratio was 9.4 (95% CI, 1.2-75.4; P = .03) for sarcopenia and osteopenia, 10.3 (95% CI, 1.3-78.8; P = .03) for sarcopenia, and 11.9 (95% CI, 1.3-107.4; P = .03) for osteopenia. Conclusions and Relevance: More than half of older trauma patients in this study had sarcopenia, osteopenia, or both. Each factor was independently associated with increased 1-year mortality. Given the prevalent use of abdominopelvic CT in trauma centers, opportunistic screening for radiologic indicators of frailty provides an additional tool for early identification of older trauma patients at high risk for poor outcomes, with the potential for targeted interventions.

Oxygen cost of exercise is increased in heart failure after accounting for recovery costs.

STUDY OBJECTIVES: The oxygen cost during exercise has been reported to be decreased in patients with congestive heart failure (CHF), implying an increased efficiency (lower oxygen uptake [VO(2)] per Watt [VO(2)/W]); however, these studies ignored the oxygen debt that is increased in heart failure. SUBJECTS: The primary aim of this research was to evaluate the total oxygen cost (work VO(2)/W) during exercise and recovery in patients with heart failure as compared with healthy adults. DESIGN AND PATIENTS: We performed a retrospective analysis comparing the exercise VO(2)/W, the recovery VO(2)/W, the work VO(2)/W, and the VO(2)/W relationship above and below the ventilatory threshold (VT) in 11 healthy control subjects and 45 patients with CHF. RESULTS: The exercise VO(2)/W was decreased by 29% (p < 0.0001) in patients with CHF; however, the recovery VO(2)/W was increased by 167% (p < 0.0001) and the work VO(2)/W was increased by 14% in patients with CHF (p = 0.014). The VO(2)/W slope increased above the VT (+ 27%, p = 0.0017) in both normal subjects and patients with CHF, suggesting a decrease in efficiency above the VT. There was an inverse correlation (r = 0.646, p < 0.0001) between exercise VO(2)/W and recovery VO(2)/W, implying that subjects with a low exercise VO(2)/W were not efficient but rather accumulated a large oxygen debt that was repaid following completion of exercise. CONCLUSIONS: Heart failure is associated with lower exercise VO(2)/W; however, the patient with heart failure is not efficient, but rather accumulating a large oxygen debt (recovery VO(2)/W) that is repaid following exercise. In addition, the work VO(2)/W (including both exercise and recovery) is increased in patients with heart failure in comparison to control subjects, and correlates inversely with the percentage of predicted VO(2). The large recovery VO(2)/W is likely due to impaired oxygen delivery to exercising muscle during exercise. The increase in the work VO(2)/W is probably due to changes in skeletal muscle fiber type that occur in patients with heart failure (type I to type IIb).
