Our ICU survivor care process results in decreased mortality and a net annual cost savings to the insurer compared with usual care processes. There was no statistically significant difference in readmission rates.

Demographic data, Acute Physiology and Chronic Health Evaluation IV scores, and Charlson Comorbidity Index scores were extracted from the electronic health record.

Additional data was extracted from the care manager database.

Economic data were extracted from the Geisinger Health Plan database and analyzed by a health economist.

During 13-month period analyzed, patients in the ICU survivor care had reduced mortality compared with usual care, as determined by the Kaplan-Meier method (ICU survivor care 0.89 vs usual care 0.71; log-rank p = 0.0108) and risk-adjusted stabilized inverse probability of treatment weighting (hazard ratio, 0.157; 95% CI, 0.058–0.427).
