Preventable hospital stays are measured as the hospital discharge rate for ambulatory care-sensitive conditions per 1,000 Medicare enrollees.
Estimates of preventable hospital stays were calculated for the County Health Rankings by the authors of the Dartmouth Atlas of Health Care using Medicare claims data.
Hospitalization for diagnoses amenable to outpatient services suggests that the quality of care provided in the outpatient setting was less than ideal. The measure may also represent the population’s tendency to overuse the hospital as a main source of care.
