Reducing length of stay improves 30 day readmission rates for some conditions

Reducing length of stay by one day improves 30 day readmission rates, according to a study in the Annals of Internal Medicine.

For the study, researchers examined data from Veteran’s hospitals for the years 1997 to 2010 for the top five conditions, which included heart failure, chronic obstructive pulmonary disease, acute myocardial infarction, community-acquired pneumonia, and gastrointestinal hemorrhage. 

The study found that length of stay was reduced by 27%, or 1.46 days, through these years.  At the same time, risk-adjusted 30-day readmissions fell by 16% and all-cause 90-day mortality improved by 3% year over year,
