Effects of the DRG-Based Prospective Payment System on Quality of Care forHospitalized Medicare Patients. Executive Summary

摘要

The study used a time series design to measure quality of care in 1981-1982,before the implementation of the prospective payment system (PPS), and in 1985-1986, after PPS implementation. Quality of care was judged using a clinically detailed review of the medical record and studying mortality, readmission, and use of nursing homes after hospital discharge. Data were collected for a nationally representative sample of Medicare patients at least 65 years old who were hospitalized with one of the study's six study conditions: congestive heart failure, acute myocardial infarction, pneumonia, cerebrovascular accident, hip fracture, and depression.
