  • Title: Pneumonia quality measures not associated with antibiotics for congestive heart failure patients.
    Author: Fee C, Johnson N, Torres H, Weber EJ.
    Journal: J Emerg Med; 2013 Mar; 44(3):577-84. PubMed ID: 23062597.
    Abstract:
    BACKGROUND: Pneumonia antibiotic timing performance measures can result in unnecessary antibiotic administration to patients in whom a diagnosis of pneumonia remains possible but has not been confirmed. OBJECTIVE: Our objective was to determine if unnecessary antibiotic administration to admissions with Emergency Department (ED) congestive heart failure (CHF) diagnoses increased as institutional attention to pneumonia antibiotic timing intensified. METHODS: We performed a cross-sectional study in an academic ED with 39,000 annual visits. Our subjects included adult admissions with ED CHF diagnoses between October and March of 2004-2005, 2005-2006, and 2006-2007. We excluded patients with any concomitant infectious diagnosis from primary analysis. We obtained patient age, sex, triage acuity, vital signs, ED diagnoses, and admitting service from electronic databases. Trained abstractors confirmed infectious diagnosis presence and noted if antibiotics were administered. Inter-observer agreement was assessed. Multivariate logistic regression determined association of time period with antibiotic administration. We assessed trends in concomitant infectious diagnoses. RESULTS: Of 778 CHF admissions, 125 had infectious diagnoses, leaving 653 for primary analysis. Inter-observer agreement was good to excellent (κ = 0.71-0.83). Demographic and presenting characteristics did not vary by period. Antibiotics were administered to 18.4% (95% confidence interval [CI] 12.7-23.3), 15.0% (95% CI 9.6-18.5), and 15.1% (95% CI 10.2-19.8), per period, respectively. Time period was not associated with antibiotics, odds ratios were 0.8 (95% CI 0.5-1.4) and 0.9 (95% CI 0.5-1.6) for periods 2 and 3, respectively. Concomitant infectious diagnoses did not increase significantly (from 15.5% to 19.4%). Pneumonia antibiotic timing compliance remained low (50-70%). CONCLUSIONS: Unnecessary antibiotic administration to ED CHF admissions did not increase as institutional scrutiny of pneumonia antibiotic timing intensified, although neither did compliance with pneumonia antibiotic timing.
