Abstract 14567: Comparison of Weekday vs. Weekend Admission on Inpatient Mortality and Total Hospital Charge on Atrial Flutter and Fibrillation: A Nationwide Analysis
Background: Weekend admissions have shown to be a predictor of inpatient mortality. We evaluated the impact of weekday vs. weekend admission in patients with Atrial Flutter and/or Fibrillation (AF) on in-hospital mortality and total hospital charge.
Methods: This is a retrospective cohort study using the 2013 National Inpatient Sample (NIS) of adult patients hospitalized with AF as the admitting diagnoses, based on ICD-9 codes. Weekday admissions, defined as Monday 12:00 AM to Friday 11:59 PM (Group 1), and weekend admissions, defined as Saturday 12:00 AM to Sunday 11:59 PM (Group 2) were compared. In-hospital mortality and total hospitalization charges were evaluated. Multivariate logistic regression was used to adjust for potential confounders including age, gender, race, hospital location, hospital region and the Charlson Comorbidity index for administrative data. STATA 13.0 was used for data analysis.
Results: 478,000 patients were identified. The mean age was 70 years and 49.9% were females. There was an inpatient mortality rate of 0.90% (4,320 patients died). After adjusting for the above factors, Group 2 had a higher inpatient mortality rate (odds ratio [OR] 1.27; P < 0.003) compared to Group 1. After adjusting for the above factors, the average total hospital charges on Group 2 ($19,130) were $3,823 less than Group 1 ($22,953) (P < 0.00).
Conclusions: There is higher inpatient mortality associated with weekend admissions for AF compared to weekday admissions. Total hospital charges are significantly lower during weekend admissions compared to weekday admissions.
