Methods to accurately and feasibly collect data in order to assess performance measures. Process to identify appropriate patient groups, healthcare providers, and/or observation periods to be included in the measurement process. Process to include outcomes of performance measurement in quality improvement strategies. Rationale Performance measures are systematic and standardized methods that are aimed at identifying and improving suboptimal medical care and patient outcomes. Performance measures represent one of several potential strategies that can be used, together or alone, to help reduce gaps in the quality of health care. Effective performance measures are those that are associated with meaningful, desirable patient outcomes and include broad sampling from appropriate and related medical domains.2 Performance measure design should follow established standards, as outlined by national organizations,2 and have precise, validated components that are feasible, actionable, and meaningful. Performance measures usually reflect clinical practice guidelines of the highest levels of recommendation and evidence. Given that the identification, treatment, and control of HBP are suboptimal,3,225,226 use of effective performance measures can help improve these gaps in care, as has been shown in 1 observational study from Kaiser Permanente of Northern California.56 No RCTs of HBP performance measures have been published.4 Implementation of Performance Measures 1. Identify performances measures for hypertension that: a. Meet established ACC/AHA standards. b. Include key components that influence the impact and sustainability of hypertension detection, treatment, and control for the target population (medical care, cost of care, patient-reported factors). c. Help address the most pressing gaps in hypertension-related care for the healthcare provider, practice, or system. Coordinate the most feasible and meaningful collection of performance measures data with available data sources (eg, electronic health records, national data registries, administrative databases).
