The seventh annual Joint Commission report summarizes the performance of hospitals across 45 accountability measures—evidence-based metrics that are directly linked to patient outcomes. This year's calculation for identifying "Top Performers" included three new accountability measure sets: stroke, venous thromboembolism, and inpatient psychiatric services. "Top Performers" are recognized by meeting two 95% performance thresholds; 620 hospitals were identified. This represents 50% more hospitals than last year and now accounts for about 18% of all Joint Commission-accredited hospitals that report core measure performance data. According to the report, hospitals have measurably improved the quality of care over the past year for heart attacks, pneumonia, surgical care, children's asthma care, inpatient psychiatric services, venous thromboembolism, and stroke patients.
