Seasonality and Readmission after Heart Failure, Myocardial Infarction, and Pneumonia.

ABSTRACT:

Objective

To investigate whether hospital readmission after admission for heart failure (HF), myocardial infarction (MI), and pneumonia varies by season.

Data sources

All patients in 2005-2009 Healthcare Cost and Utilization Project State Inpatient Databases for New York and California hospitalized for HF, MI, or pneumonia.

Study design

The relationship between discharge season and unplanned readmission within 30 days was evaluated using multivariate modified Poisson regression.

Principal findings

Cohorts included 869,512 patients with HF, 448,945 patients with MI, and 813,593 patients with pneumonia. While admissions varied widely by season, readmission rates only ranged from 25.0 percent (spring) to 25.6 percent (winter) for HF (p > .05), 18.9 percent (summer
