AbstractObjectivesMany guidelines for septic olecranon bursitis recommend aspiration of the bursa prior to initiation of antimicrobial therapy despite the absence of robust clinical data to support this practice and known risk of aspiration complications. Our objective was to describe outcomes associated with empiric antibiotic therapy without bursal aspiration among emergency department (ED) patients with suspected septic olecranon bursitis.MethodsWe conducted a retrospective observational cohort study of patients presenting to an academic ED from January 1, 2011, to December 31, 2018, with olecranon bursitis. The health record was reviewed to assess patient characteristics and outcomes within 6 months of the ED visit. Olecranon bursitis was considered “suspected septic” if the patient was treated with antibiotics. The primary outcome of interest was complicated versus uncomplicated bursitis resolution. Uncomplicated resolution was defined as bursitis resolution without subsequent bursal aspiration, surgery, or hospitalization.ResultsDuring the study period, 264 ED patients were evaluated for 266 cases of olecranon bursitis. The median age was 57 years and 85% were men. Four (1.5%) patients had bursal aspiration during their ED visit, 39 (14.7%) were admitted to the hospital, 76 (28.6%) were dismissed without antibiotic therapy, and 147 (55.3%) were dismissed with empiric antibiotic therapy for suspected septic olecranon bursitis. Among these 147 patients, 134 had follow‐up available including 118 (88.1%, 95% confidence interval [CI] = 81.1%–92.8%) with an uncomplicated resolution, eight (6.0%, 95% CI = 2.8%–11.8%) who underwent subsequent bursal aspiration, and nine (6.7%, 95% CI = 3.3%–12.7%) who were subsequently admitted for inpatient antibiotics.ConclusionsEighty‐eight percent of ED patients with suspected septic olecranon bursitis treated with empiric antibiotics without aspiration had resolution without need for subsequent bursal aspiration, hospitalization, or surgery. Our findings suggest that empiric antibiotics without bursal aspiration may be a reasonable initial approach to ED management of select patients with suspected septic olecranon bursitis.

Background Premature coronary artery disease ( CAD ) is common in patients with coarctation of aorta ( COA ), but there are limited data about any direct relationship (or lack thereof) between COA and CAD . We hypothesized that atherosclerotic cardiovascular disease risk factors, rather than COA diagnosis, was the primary determinant of CAD occurrence in patients with COA . Methods and Results This is a retrospective study of 654 COA patients and a control group of 876 patients with valvular pulmonic stenosis and tetralogy of Fallot to determine prevalence and independent risk factors for CAD . There was no evidence of a difference in the unadjusted CAD prevalence between the COA and control groups (7.8% versus 6.3%, P =0.247), but premature CAD was more common in COA patients (4.4% versus 1.8%, P =0.002). In the analysis of a propensity‐matched cohort of 126 COA and 126 control patients, there was no evidence of a difference in overall CAD prevalence (6.3% versus 5.6% versus P =0.742) and premature CAD prevalence (4.8% versus 3.2%, P =0.518). The multivariable risk factors for CAD were hypertension (odds ratio [ OR ] 2.14; 95% CI 1.36–3.38), hyperlipidemia ( OR 3.33; 95% CI 2.02–5.47), diabetes mellitus ( OR 1.98; 95% CI 1.31–3.61), male sex ( OR 2.05; 95% CI 1.33–3.17), and older age per year ( OR 1.06; 95% CI 1.04–1.07). Conclusions After adjusting for atherosclerotic cardiovascular disease risk factors, we did not find evidence of a difference in CAD risk between the patients with COA and other patients with congenital heart disease.
