Key result
Patients discharged in the winter were significantly more likely to be readmitted within 30 days compared to those discharged in the summer (OR 1.54).
Why the study?
Are institution-specific factors associated with 30-day readmission rates in patients discharged with congestive heart failure, pneumonia, or chronic obstructive pulmonary disease?

Park et al. (2014) conducted an observational in Congestive heart failure, pneumonia, or chronic obstructive pulmonary disease (n=3,774). Winter discharge vs. Summer discharge was evaluated on 30-day readmission (OR 1.54, 95% CI 1.20, 1.98, p=0.0008). Patients discharged in the winter were significantly more likely to be readmitted within 30 days compared to those discharged in the summer (OR 1.54).
