Participation in a standardized quality-of-care data registry designed to track and measure outcomes, complications, and performance measures can be beneficial in improving the quality of NSTE-ACS care.2,152,154 160 (Class IIa, Level of Evidence: B) ACC indicates American College of Cardiology; ACCF, American College of Cardiology Foundation; AHA, American Heart Association; AMI acute myocardial infarction; D2B, Door-to-Balloon; NCDR, National Cardiovascular Data Registry; NSTE-ACS, non ST-elevation acute coronary syndrome; and STEMI, ST-elevation myocardial infarction. Appendix A. Continued 34 Quality Improvement Measures for Inpatient STEMI and NSTEMI Patients Inpatient Measures Short Title: QM-1: Risk Score Stratification for NSTEMI QM-1: NSTEMI: Risk Stratification of NSTEMI Patients With a Risk Score Measure Description: Percentage of patients, age 18 y, hospitalized with NSTEMI, who have a risk stratification score documented during hospitalization. Numerator Patients with NSTEMI who have a risk score documented during hospitalization Examples of commonly utilized risk stratification scores include: TIMI risk score GRACE risk score Denominator All patients with NSTEMI Denominator Exclusions Patients age <18 y Patients who leave against medical advice Patients who die during hospitalization Patients who are on comfort care measures only or hospice Patients who are transferred to another hospital for inpatient acute care Denominator Exceptions None Measurement Period Encounter Sources of Data Medical record or other database (eg, administrative, clinical, registry) Attribution Measure reportable at the facility or provider level Care Setting Inpatient Rationale Objective risk stratification with validated risk scores help triage and dictate the initial treatment strategy in patients with NSTEMI. For example, those at high-risk will likely benefit from an early invasive strategy (within 12 to 24 h), while intermediate-risk patients may receive delayed invasive strategy (within 24 to 72 h).
