Abstract 15775: Impact of Month of the Year and Weekend Admissions on Inpatient Mortality and Cost Burden for Congestive Heart Failure in 2013
Background: Seasonal variation occurs in all cardiovascular events, including Congestive Heart Failure (CHF) hospitalizations. Worldwide data suggests a temporal periodicity of hospitalization regarding heart failure with peaks during winter months. We aim to assess the impact of monthly, seasonal, and weekend admissions of CHF hospitalizations.
Methods: This is a retrospective cohort study using the 2013 National Inpatient Sample (NIS) of adult patients hospitalized with CHF as the admitting diagnosis. Our outcomes included inpatient mortality and hospital charges; adjusted for age and gender.
Results: We included a total of 880,819 patients admitted with CHF. The probability of inpatient mortality increased 12% during the months of October to March in comparison with patients admitted during April to September (OR:1.12; p<0.00). There was no significant different in inpatient mortality if they were admitted during the weekend (OR: 1.00; p=0.84). Hospital charges for patients admitted with CHF were higher during October to March when compared to April to September (p<0.01). The mean hospital charge per patient admitted during October to March was US$ 52, 528 and during April to September was US$ 50,861.
Conclusion: There is higher inpatient mortality during fall and winter as well as hospital charges. January and December were the months with higher mortality among patient admitted for CHF. Inpatient mortality was not affected by weekend admissions.
