Item Open Access Patterns of Emergency Care for Possible Acute Coronary Syndrome Among Patients with Chest Pain or Shortness of Breath at a Tanzanian Referral Hospital.(Global heart, 2020-02-06) Hertz, Julian T; Kweka, Godfrey L; Bloomfield, Gerald S; Limkakeng, Alexander T; Loring, Zak; Temu, Gloria; Mmbaga, Blandina T; Gerardo, Charles J; Sakita, Francis MBackground:Acute coronary syndrome (ACS) is thought to be a rare diagnosis in sub-Saharan Africa, but little is known about diagnostic practices for patients with possible ACS symptoms in the region. Objective:To describe current care practices for patients with ACS symptoms in Tanzania to identify factors that may contribute to ACS under-detection. Methods:Emergency department patients with chest pain or shortness of breath at a Tanzanian referral hospital were prospectively observed. Medical histories were obtained, and diagnostic workups, treatments, and diagnoses were recorded. Five-year risk of cardiovascular events was calculated via the Harvard National Health and Nutrition Examination Survey risk score. Telephone follow-ups were conducted 30 days after enrollment. Results:Of 339 enrolled patients, the median (IQR) age was 60 (46, 72) years, 252 (74.3%) had hypertension, and 222 (65.5%) had >10% five-year risk of cardiovascular event. The median duration of symptoms prior to presentation was 7 days, and 314 (92.6%) reported symptoms worsened by exertion. Of participants, 170 (50.1%) received an electrocardiogram, and 9 (2.7%) underwent cardiac biomarker testing. There was no univariate association between five-year cardiovascular risk and decision to obtain an electrocardiogram (p = 0.595). The most common physician-documented diagnoses were symptomatic hypertension (104 patients, 30.7%) and heart failure (99 patients, 29.2%). Six patients (1.8%) were diagnosed with ACS, and 3 (0.9%) received aspirin. Among 284 (83.8%) patients completing 30-day follow-up, 20 (7.0%) had died. Conclusions:Many patients with ACS risk factors present to the emergency department of a Tanzanian referral hospital with possible ACS symptoms, but marked delays in care-seeking are common. Complete diagnostic workups for ACS are uncommon, ACS is rarely diagnosed or treated with evidence-based therapies, and mortality in patients with these symptoms is high. Physician practices may be contributing to ACS under-detection in Tanzania, and interventions are needed to improve ACS care.Item Open Access Risk stratification with video capsule endoscopy leads to fewer hospital admissions in emergency department patients with low-risk to moderate-risk upper gastrointestinal bleed: A multicenter clinical trial.(J Am Coll Emerg Physicians Open, 2021-10) Meltzer, Andrew C; Limkakeng, Alexander T; Gentile, Nina T; Freeman, Jincong Q; Hall, Nicole C; Vargas, Nataly Montano; Fleischer, David E; Malik, Zubair; Kallus, Samuel J; Borum, Marie L; Ma, Yan; Kumar, Anita BObjective: In US emergency departments (EDs), the physician has limited ability to evaluate for common and serious conditions of the gastrointestinal (GI) mucosa such as a bleeding peptic ulcer. Although many bleeding lesions are self-limited, the majority of these patients require emergency hospitalization for upper endoscopy (EGD). We conducted a clinical trial to determine if ED risk stratification with video capsule endoscopy (VCE) reduces hospitalization rates for low-risk to moderate-risk patients with suspected upper GI bleeding. Methods: We conducted a randomized controlled trial at 3 urban academic EDs. Inclusion criteria included signs of upper GI bleeding and a Glasgow Blatchford score <6. Patients were randomly assigned to 1 of the following 2 treatment arms: (1) an experimental arm that included VCE risk stratification and brief ED observation versus (2) a standard care arm that included admission for inpatient EGD. The primary outcome was hospital admission. Patients were followed for 7 and 30 days to assess for rebleeding events and revisits to the hospital. Results: The trial was terminated early as a result of low accrual. The trial was also terminated early because of a need to repurpose all staff to respond to the coronavirus disease 2019 pandemic. A total of 24 patients were enrolled in the study. In the experimental group, 2/11 (18.2%) patients were admitted to the hospital, and in the standard of care group, 10/13 (76.9%) patients were admitted to the hospital (P = 0.012). There was no difference in safety on day 7 and day 30 after the index ED visit. Conclusions: VCE is a potential strategy to decrease admissions for upper GI bleeding, though further study with a larger cohort is required before this approach can be recommended.Item Open Access Sex differences in the prevalence and correlates of emergency department utilization among adults with prescription opioid use disorder.(Substance use & misuse, 2019-01) John, William S; Wu, Li-TzyBACKGROUND:The emergency department (ED) is well-suited as an opportunity to increase treatment access for prescription opioid use disorder (POUD). We examined sex differences in ED utilization among individuals with POUD to understand potential sex-specific treatment barriers and needs. METHODS:Data from the 2005-2014 National Surveys on Drug use and Health were analyzed to examine the prevalence and correlates of past-year ED utilization among male and female adults aged 18 or older with POUD (n = 4412). RESULTS:Overall, 58.2% of adults with POUD reported past-year ED utilization. Adjusted logistic regression revealed that females (vs. males) with POUD were more likely to report past-year ED utilization. Among females with POUD, older age, lower income, obtaining opioids from a physician, major depressive episode, and greater POUD severity were associated with increased odds of ED utilization. Among males with POUD, public insurance and obtaining opioids from a physician were associated with ED utilization. A larger proportion of males with POUD reporting ED use had multiple substance use disorders than those with no ED use. Treatment history (lifetime or past-year) for alcohol, drugs, or opioid use was associated with increased odds of ED use among males and females with POUD. Conclusions/Importance: Males and females with POUD presenting to the ED may have distinct predisposing, enabling, and need-related correlates. Sex-specific screening and intervention strategies may be useful to maximize the utility of the ED to address POUD.Item Open Access Simplified Predictive Instrument to Rule Out Acute Coronary Syndromes in a High-Risk Population.(J Am Heart Assoc, 2015-12-14) Fanaroff, Alexander C; Schulteis, Ryan D; Pieper, Karen S; Rao, Sunil V; Newby, L KristinBACKGROUND: It is unclear whether diagnostic protocols based on cardiac markers to identify low-risk chest pain patients suitable for early release from the emergency department can be applied to patients older than 65 years or with traditional cardiac risk factors. METHODS AND RESULTS: In a single-center retrospective study of 231 consecutive patients with high-risk factor burden in which a first cardiac troponin (cTn) level was measured in the emergency department and a second cTn sample was drawn 4 to 14 hours later, we compared the performance of a modified 2-Hour Accelerated Diagnostic Protocol to Assess Patients with Chest Pain Using Contemporary Troponins as the Only Biomarker (ADAPT) rule to a new risk classification scheme that identifies patients as low risk if they have no known coronary artery disease, a nonischemic electrocardiogram, and 2 cTn levels below the assay's limit of detection. Demographic and outcome data were abstracted through chart review. The median age of our population was 64 years, and 75% had Thrombosis In Myocardial Infarction risk score ≥2. Using our risk classification rule, 53 (23%) patients were low risk with a negative predictive value for 30-day cardiac events of 98%. Applying a modified ADAPT rule to our cohort, 18 (8%) patients were identified as low risk with a negative predictive value of 100%. In a sensitivity analysis, the negative predictive value of our risk algorithm did not change when we relied only on undetectable baseline cTn and eliminated the second cTn assessment. CONCLUSIONS: If confirmed in prospective studies, this less-restrictive risk classification strategy could be used to safely identify chest pain patients with more traditional cardiac risk factors for early emergency department release.
