Correlations among common emergency medicine physician performance measures: Mixed messages or balancing forces?

The increasing complexity of ED physician performance measures has resulted in significant challenges, including duplicative and conflicting measures that fail to account for different ED settings. We performed a cross sectional analysis of correlations between measures to characterize their relationships and determine if differences exist between academic versus non-academic ED settings. Pearson correlations were calculated for 12 measures among 220 ED physicians at 11 EDs. Higher admission rate was strongly correlated with higher CT utilization rate (R = 0.7, p < 0.01) and longer room to discharge time (R = 0.7, p < 0.01). Higher patients per hour was strongly correlated with shorter room to doctor time (R = -0.7, p < 0.01). Stronger measure correlations were found in the academic setting compared to the non-academic setting. Strong correlations between ED measures imply opportunities to reduce competing performance demands on clinicians. Differences in correlations at academic versus non-academic settings suggest that it may be inappropriate to apply the same performance standards across settings.

Impact of Chronic Total Occlusions on Outcomes of Patients With Acute Myocardial Infarction Undergoing Percutaneous Coronary Intervention: A Propensity-Score-Matched Analysis Using the National Inpatient Sample Database.

BACKGROUND: There is limited data on the impact of chronic total occlusions (CTOs) on the outcomes of patients presenting with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) in the contemporary era. METHODS: We queried the National Inpatient Sample between October 2015 and December 2017 using the International Classification of Diseases, Tenth revision codes to identify hospitalized AMI patients undergoing PCI. A 1:1 propensity-score matched analysis was performed to compare in-hospital outcomes of patients with and without CTOs. RESULTS: Among 576,760 admissions identified during the study period, 51,225(8.8 %) had CTO and 525,535 (91.1 %) did not. After 1:1 propensity-score matching, each matched group contained 51,210 admissions. In-hospital mortality was significantly higher in the CTO group compared with the non-CTO group (4.7 % vs 3 %, p < 0.0001). In the CTO group, hospital length of stay was longer (median 3 vs 2 days, p = 0.001) and lower percentage of patients were discharged to home (78.8 % vs 81.1 %, p < 0.0001), compared with the non-CTO group. Median cost of hospital stay was also higher in the CTO group compared with the non-CTO group ($20,921 vs $19,856, p < 0.0001). CONCLUSIONS: In this propensity-score matched analysis of a large US inpatient database, the presence of CTOs in AMI patients undergoing PCI identified a higher risk cohort with in higher in-hospital mortality, longer hospital length of stay and higher hospitalization cost.

Improving Emergency Department Throughput Using Audit-and-Feedback With Peer Comparison Among Emergency Department Physicians.

INTRODUCTION: We sought to determine if audit-and-feedback with peer comparison among emergency physicians is associated with improved emergency department (ED) throughput and decreased variation in physician performance. METHODS: We implemented an audit-and-feedback with peer comparison tool at a single urban academic ED from March 1, 2013, to July 1, 2018. In the first study period, physicians received no reports. In the second period, they received daily reports. In the third period, they received daily, quarterly, and annual reports. Outcomes included patients per hour, admission rate, time to admission, and time to discharge. RESULTS: A total of 272,032 patient visits and 36 ED physicians were included. The mean admission rate decreased 6.8%; the mean time to admission decreased 43.8 minutes; and the mean time to discharge decreased 40.6 minutes. Variation among physicians decreased for admission rate, time to admission, and time to discharge. Low-performing outliers showed disproportionately larger improvements in patients per hour, admission rate, time to admission, and time to discharge. CONCLUSIONS: Automated peer comparison reports for academic emergency physicians was associated with lower admission rates, shorter times to admission, and shorter times to discharge at the departmental level, as well as decreased practice variation at the individual level.

The Association of Preinfection Daily Oral Anticoagulation Use and All-Cause in Hospital Mortality From Novel Coronavirus 2019 at 21 Days: A Retrospective Cohort Study.

OBJECTIVES: Practices regarding anticoagulation use in coronavirus disease 2019 focus primarily on its efficacy in the critically ill without a clear understanding of when to begin anticoagulation. We sought to understand the association of preinfection daily oral anticoagulation use and the short-term mortality of patients hospitalized with coronavirus disease 2019. DESIGN: Retrospective chart review. SETTING: Large health system with high coronavirus disease 2019 prevalence. PATIENTS: Patients 60 years or older admitted to the hospital with positive coronavirus disease 2019 polymerase chain reaction test. INTERVENTIONS: We compared both those on warfarin and those on a direct oral anticoagulant prior to admission and throughout disease course with those who were never exposed to an oral anticoagulant. RESULTS: Our primary outcome was inhospital mortality at 21 days from the first coronavirus disease 2019 test ordered. Patients in the direct oral anticoagulant group (n = 104) were found to have significantly lower 21-day all-cause in hospital mortality than patients in the control group (n = 894) both prior to adjustment (14.4% vs 23.8%; odds ratio, 0.57 [0.29-0.92]; p = 0.03) and after controlling for age, gender, and comorbidities (odds ratio, 0.44 [0.20-0.90]; p = 0.033). Patients on warfarin (n = 28) were found to have an elevated unadjusted mortality rate of 32% versus 23.8% in the control group (odds ratio, 1.51 [0.64-3.31]; p = 0.31). After adjustment, a reduction in mortality was observed but not found to be statistically significant (odds ratio, 0.29 [0.02-1.62]; p = 0.24). There was no statistical difference noted in the number of bleeding events in each group. CONCLUSIONS: In this retrospective cohort study evaluating oral anticoagulant use among patients with coronavirus disease 2019, we found that patients who are on daily oral anticoagulation at the time of infection and throughout their disease course had significantly lower risk of all-cause mortality at 21 days. Validation of these findings should be performed on population-based levels. While research regarding anticoagulation algorithms is ongoing, we believe these results support future randomized control trials to understand the efficacy and risk of the use of early oral anticoagulation.

Northwell intracoronary brachytherapy for the treatment of recurrent drug eluting stent in-stent restenosis (NITDI study group).

OBJECTIVE: The purpose of this study is to report on safety, short-term and long-term clinical efficacy following intracoronary brachytherapy (ICBT) for restenosis (ISR) in patients with drug eluting stents (DES). BACKGROUND: ICBT is an effective treatment for ISR of bare metal stents (BMS) but its utilization has waned due to the advent of DES. ISR following DES occurs at a frequency of 8% or greater. METHOD: A retrospective analysis was performed on patients treated on an institutional review board (IRB) approved protocol using ICBT for DES ISR between January 2011 and October 2016. All patients were followed for 24 months for procedural complications, mortality, clinical ISR/target lesion revascularization (TLR) and stroke. RESULTS: A total of 290 patients were identified with a mean age of 66.6 years. All of them had high rates of typical coronary artery disease risk factors. Our primary outcome, composite of in-hospital mortality, myocardial infarction (MI), safety outcomes and procedural failure was noted in 1(0.3%) patient who had a MI. No other secondary outcome was noted in-hospital. At 1-year follow up, 12.4% patients had ISR, 1.7% patients died, and 1 (0.3%) had ischemic stroke. At 2-year, 14.7% had ISR, and total 6 (2.1%) patients had MI. CONCLUSION: ICBT demonstrates excellent technical success rates for treatment, safety, and reasonable efficacy over 2-years to be free from recurrent clinical ISR. This study represents the largest ICBT data for DES ISR to date among very complex lesion subsets, however, more prospective data will be needed to determine the optimal patient for treatment.

Study protocol for the ACT response pilot intervention: development, implementation and evaluation of a systems-based Agitation Code Team (ACT) in the emergency department.

INTRODUCTION: Emergency department (ED) visits for behavioural conditions are rising, with 1.7 million associated episodes of patient agitation occurring annually in acute care settings. When de-escalation techniques fail during agitation management, patients are subject to use of physical restraints and sedatives, which are associated with up to 37% risk of hypotension, apnoea and physical injuries. At the same time, ED staff report workplace violence due to physical assaults during agitation events. We recently developed a theoretical framework to characterise ED agitation, which identified teamwork as a critical component to reduce harm. Currently, no structured team response protocol for ED agitation addressing both patient and staff safety exists. METHODS AND ANALYSIS: Our proposed study aims to develop and implement the agitation code team (ACT) response intervention, which will consist of a standardised, structured process with defined health worker roles/responsibilities, work processes and clinical protocols. First, we will develop the ACT response intervention in a two-step design loop; conceptual design will engage users in the creation of the prototype, and iterative refinement will occur through in situ simulated agitated patient encounters in the ED to assess and improve the design. Next, we will pilot the intervention in the clinical environment and use a controlled interrupted time series design to evaluate its effect on our primary outcome of patient restraint use. The intervention will be considered efficacious if we effectively lower the rate of restraint use over a 6-month period. ETHICS AND DISSEMINATION: Ethical approval by the Yale University Human Investigation Committee was obtained in 2019 (HIC #2000025113). Results will be disseminated through peer-reviewed publications and presentations at scientific meetings for each phase of the study. If this pilot is successful, we plan to formally integrate the ACT response intervention into clinical workflows at all EDs within our entire health system.

Immune Reconstitution Syndrome with Initiation of Treatment of HBV/HIV Co-infection: Activity Flare associated with E antigen Seroconversion.

Immune reconstitution syndrome is a recognized complication with initiation of highly active antiretroviral therapy for acquired immune deficiency syndrome patients co-infected with hepatitis B. Hepatitis B flares are seen in 20%-25% of patients after initiation of highly active antiretroviral therapy, an estimated 1%-5% of whom develop clinical hepatitis. We present a case of highly active antiretroviral therapy initiation for HIV that led to a flare of HBV activity despite antiviral therapy directed towards both. Liver biopsy and longitudinal serologic evaluation lend support to the hypothesis that the flare in activity was representative of IRIS. Importantly, we document eAg/eAb seroconversion with the IRIS phenomenon.

Opening of Psychiatric Observation Unit Eases Boarding Crisis.

OBJECTIVES: The objective of this study was to evaluate the effect of a psychiatric observation unit in reducing emergency department (ED) boarding and length of stay (LOS) for patients presenting with primary psychiatric chief complaints. A secondary outcome was to determine the effect of a psychiatric observation unit on inpatient psychiatric bed utilization. METHODS: This study was a before-and-after analysis conducted in a 1,541-bed tertiary care academic medical center including an adult ED with annual census over 90,000 between February 2013 and July 2014. All adult patients (age > 17 years) requiring evaluation by the acute psychiatry service in the crisis intervention unit (CIU) within the ED were included. Patients who left without being seen, left against medical advice, or were dispositioned to the pediatric hospital, hospice, or court/law enforcement were excluded. In December 2013, a 12-bed locked psychiatric observation unit was opened that included dedicated behavioral health staff and was intended for psychiatric patients requiring up to 48 hours of care. The primary outcomes were ED LOS, CIU LOS, and total LOS. Secondary outcomes included the hold rate defined as the proportion of acute psychiatry patients requiring subsequent observation or inpatient admission and the inpatient psychiatric admission rate. For the primary analysis we constructed ARIMA regression models that account for secular changes in the primary outcomes. We conducted two sensitivity analyses, first replicating the primary analysis after excluding patients with concurrent acute intoxication and second by comparing the 3-month period postintervention to the identical 3-month period of the prior year to account for seasonality. RESULTS: A total of 3,501 patients were included before intervention and 3,798 after intervention. The median ED LOS for the preintervention period was 155 minutes (interquartile range [IQR] = 19-346 minutes), lower than the median ED LOS for the postintervention period of 35 minutes (IQR = 9-209 minutes, p < 0.0001). Similar reductions were observed in CIU LOS (865 minutes vs. 379 minutes, p < 0.0001) and total LOS (1,112 minutes vs. 920 minutes, p = 0.003). The psychiatric hold rate was statistically higher after intervention (before = 42%, after = 50%, p < 0.0001), however, coupled with a statistically lower psychiatric admission rate (before = 42%, after = 25%, p < 0.0001). CONCLUSIONS: Creation of an acute psychiatric observation improves ED and acute psychiatric service throughput while supporting the efficient allocation of scare inpatient psychiatric beds. This novel approach demonstrates the promise of extending successful observation care models from medical to psychiatric illness with the potential to improve the value of acute psychiatric care while minimizing the harms of ED crowding.

Profiling Neutrophil-to-Lymphocyte Ratio Changes in Response to Nucleoside Analog Therapy for Chronic Hepatitis B Infection.

BACKGROUND/AIM: The neutrophil-lymphocyte ratio (NLR) has gained attention as an index of inflammation in patients with chronic hepatitis B virus (HBV); however, changes with nucleoside analog therapy require investigation. PATIENTS AND METHODS: We carried out a retrospective study identifying monoinfected HBV patients initiated on therapy with NLR follow-up over 1 year. Biochemistries recorded at treatment initiation and 1 year included alanine aminotransferase (ALT), Model for End Stage Liver Disease (MELD) score, and NLR. RESULTS: A total of 67 patients were initiated on therapy and had baseline characteristics including e-antigen (eAg) (50, 74.6%) and cirrhosis (19, 28.4%). On subgroup analysis among those with HBV-associated cirrhosis, the NLR decreased over 1 year (3.08±0.39 vs. 1.77±0.18, p<0.001) as did MELD and ALT. Among the non-cirrhotic cohort, there was no difference in NLR (1.99±0.89 vs. 2.14±1.03, p=0.134) despite a decrease in ALT. CONCLUSION: Nucleoside analog therapy in HBV cirrhosis is associated with a decrease in NLR over 1 year that tracks with changes of established indices of inflammation/global hepatic function.

Primary Biliary Cholangitis: Disease Pathogenesis and Implications for Established and Novel Therapeutics.

Primary Biliary Cholangitis is a progressive, autoimmune cholestatic liver disorder. Cholestasis with disease progression may lead to dyslipidemia, osteodystrophy and fat-soluble vitamin deficiency. Portal hypertension may develop prior to advanced stages of fibrosis. Untreated disease may lead to cirrhosis, hepatocellular cancer and need for orthotopic liver transplantation. Classically, diagnosis is made with elevation of alkaline phosphatase, demonstration of circulating antimitochondrial antibody, and if performed: asymmetric destruction/nonsupperative cholangitis of intralobular bile ducts on biopsy. Disease pathogenesis is complex and results from innate and adaptive (cell-mediated and humoral) responses that lead to inflammation of biliary duct epithelium. Ongoing damage is amplified and sustained through bile acid toxicity. Use of weight based (13-15mg/kg) ursodeoxycholic acid is well established in retarding disease progression and improving survival; however, is ineffective in achieving complete biochemical remission in many. Recently, a Farnesoid X Receptor agonist, obeticholic acid, has been approved for use. A number of ongoing clinical studies are underway to evaluate utility of fibric acid derivatives, biologics, antifibrotics, and stem cells as monotherapy or in combination with ursodeoxycholic acid for primary biliary cholangitis. The aim of this review is to discuss disease pathogenesis and highlight rationale/implications for both established and novel therapeutics.

Comparison of traditional trigger tool to data warehouse based screening for identifying hospital adverse events.

BACKGROUND: Research supports medical record review using screening triggers as the optimal method to detect hospital adverse events (AE), yet the method is labour-intensive. METHOD: This study compared a traditional trigger tool with an enterprise data warehouse (EDW) based screening method to detect AEs. We created 51 automated queries based on 33 traditional triggers from prior research, and then applied them to 250 randomly selected medical patients hospitalised between 1 September 2009 and 31 August 2010. Two physicians each abstracted records from half the patients using a traditional trigger tool and then performed targeted abstractions for patients with positive EDW queries in the complementary half of the sample. A third physician confirmed presence of AEs and assessed preventability and severity. RESULTS: Traditional trigger tool and EDW based screening identified 54 (22%) and 53 (21%) patients with one or more AE. Overall, 140 (56%) patients had one or more positive EDW screens (total 366 positive screens). Of the 137 AEs detected by at least one method, 86 (63%) were detected by a traditional trigger tool, 97 (71%) by EDW based screening and 46 (34%) by both methods. Of the 11 total preventable AEs, 6 (55%) were detected by traditional trigger tool, 7 (64%) by EDW based screening and 2 (18%) by both methods. Of the 43 total serious AEs, 28 (65%) were detected by traditional trigger tool, 29 (67%) by EDW based screening and 14 (33%) by both. CONCLUSIONS: We found relatively poor agreement between traditional trigger tool and EDW based screening with only approximately a third of all AEs detected by both methods. A combination of complementary methods is the optimal approach to detecting AEs among hospitalised patients.

Tuberculous peritonitis and tuberculous endometritis diagnosed in the same patient by high clinical suspicion and a minimally invasive approach.

Tuberculous peritonitis and tuberculous endometritis are extremely rare entities in the Western world. In this article, we discuss a rare case of a 40-year-old Nigerian female presenting with abdominal pain, distension and secondary amenorrhea, and show that a high clinical suspicion combined with minimally invasive procedures can help physicians make the diagnosis, avoid extensive surgery, and rapidly initiate appropriate therapy.
