An Organization-Specific and Modifiable Inpatient Safety Composite Measure

Abstract

In early 2013, seeking to apply the principles of value-based purchasing to all Kaiser Permanente hospitals as part of an existing organizationwide value-based performance incentive plan, Kaiser Permanente developed an inpatient safety composite measure that tracks hospital-level performance improvement related to 10 key inpatient safety events. The elements of the composite are weighted equally, and the tool draws on scoring methodologies used by the National Committee for Quality Assurance and the Centers for Medicare & Medicaid Services Hospital Inpatient Value-Based Purchasing Program. Two years after implementation of the composite measure, hospitals experienced improvement across 9 of the 10 adverse events assessed, though only one improvement achieved statistical significance. The measure successfully distinguishes four levels of improvement and is broadly applicable to hospitals and hospital systems.
