Key result
Unplanned 30-day hospital readmission linked to ~381% higher one-year mortality.
Why the study?
Predictors of 1-year mortality from index hospital stay factors and whether 30-day post-discharge healthcare system use is associated with 1-year mortality remained to be identified.
Cohort (n=934)
Yes
Odds Ratio: 4.81 (95% CI 2.77–8.33)
p-value: p=<0.001
A high early simplified HOSPITAL score, not living at home, and a 30-day unplanned readmission are strong predictors of one-year mortality in general medical patients discharged from the hospital.
Supports risk stratification via HOSPITAL score and readmission status; leaves open whether preventing readmissions improves one-year survival.

Liechti et al. (2023) conducted a cohort in General internal medicine inpatients (n=934). 30-day unplanned hospital readmission vs. No 30-day unplanned readmission was evaluated on All-cause mortality at one year after hospital discharge (OR 4.81, 95% CI 2.77-8.33, p=<0.001). A 30-day unplanned hospital readmission was strongly associated with increased one-year mortality (OR 4.81), alongside a high early simplified HOSPITAL score and not living at home.
