Quality of Care and Outcomes for UA/NSTEMI: Recommendation (See Table 9.) 7.1.1. Quality Care and Outcomes The development of regional systems of UA/NSTEMI care is a matter of utmost importance.196,198,199 This includes encouraging the participation of key stakeholders in collaborative efforts to evaluate care using standardized performance and quality- improvement measures, such as those endorsed by the ACC and the AHA for UN/NSTEMI.199 Standardized quality-of-care data registries designed to track and measure outcomes, complica- tions, and adherence to evidence-based processes of care for UA/NSTEMI are also critical: programs such as the NCDR (National Cardiovascular Data Registry) ACTION Registry- GWTG, the AHA s Get With The Guidelines (GWTG) quality- improvement program, and those performance-measurement systems required by The Joint Commission and the Centers for Medicare and Medicaid Services.194,201 203 More recently, the AHA has promoted its Mission: Lifeline initiative, which was developed to encourage closer cooperation and trust among prehospital emergency services personnel and cardiac care professionals.194 The evaluation of UA/NSTEMI care delivery across traditional care-delivery boundaries with these tools and other resources is imperative to identify systems problems and enable the application of modern quality-improvement methods, such as Six Sigma, to make necessary improve- ments.195,197,200,204 The quality-improvement data coming from registries like the ACTION-GTWG may prove pivotal in ad- dressing opportunities for quality improvement at the local, regional, and national level, including the elimination of health- care disparities and conduct of comparative effectiveness research.
