Top hospitals attract more patients
Hospitals that were better at treating heart attacks, heart failure, and adhered to standard processes of care also attracted more patients than competitors. The red line represents a baseline hospital, and the data points reflect the number of patients who went to a higher quality institution in the same market.
Note: High-quality hospitals had 1 pct. point higher survival rate, 1 pct. point lower readmission rate, 1-standard-deviation increase in process of care and patient satisfaction.
