15 top health systems named by IBM Watson Health
The company, which has conducted the study annually since 2008, said the top-performing health systems achieved better risk-adjusted outcomes and higher patient satisfaction scores, while maintaining a lower average cost per patient than other health systems evaluated in the study.
Benchmarks for the study
This year, researchers began testing a series of new measures that update the basic standards of inpatient care, including outpatient imaging efficiency for breast and chest scans; process of care for severe sepsis and septic shock; 30-day all-cause, hospital-wide readmissions; 30- and 90-day episode of care payment measures; excess days in acute care measures; and 90-day complication measures.
• Overall, 13.8 percent fewer in-hospital deaths.
• Patients experienced 12.6 percent fewer complications and 9.8 percent fewer healthcare-associated infections.
• A median severity-adjusted length of stay that was one half-day shorter than peers.
• Overall, median emergency department wait times were 38 minutes shorter per patient.
• Combined in-hospital and post-discharge costs were 1.1 percent lower per episode.
• Overall hospital experience, as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), was rated 2.5 percent higher for leading health systems.
