Key result
A 1-day decrease in hospital length of stay was associated with a 1.56 percentage point increase in 30-day rehospitalization for AMI with major complications (95% CI 0.30-2.82).

May warrant caution shortening LOS in AMI with major complications; leaves open causality and generalizability beyond this observational subgroup.

Does reducing length of stay increase 30-day rehospitalization in Medicare fee-for-service beneficiaries discharged to skilled nursing facilities?
Effect estimate: Absolute increase 1.56 percentage points (95% CI 0.30-2.82)
Reducing hospital length of stay by 1 day does not consistently increase 30-day rehospitalization rates, though it may increase risk for specific high-risk groups such as those with AMI and major complications.
Unruh et al. (2013) conducted a cohort in Hospitalization (n=2,101,481). 1-day decrease in length of stay vs. Standard length of stay was evaluated on 30-day rehospitalization (Absolute increase 1.56 percentage points, 95% CI 0.30-2.82). A 1-day decrease in hospital length of stay was associated with a 1.56 percentage point increase in 30-day rehospitalization for AMI with major complications (95% CI 0.30-2.82).
