The writing committee also exam- ined available information on gaps in care to address which new measures might be appropriate as perfor- mance measures or quality measures for this measure set update, based on the attributes for performance measures outlined in Table 7. 3. AHA/ACC HBP MEASURE SET PERFORMANCE MEASURES 3.1. Discussion of Changes to 2011 Hypertension Measure Set After reviewing the existing guidelines and the 2011 hypertension measure set,3 the writing committee dis- cussed which measures required revision to reflect updat- ed science related to HBP and identified which guideline recommendations could serve as the basis for new per- formance or quality measures. The writing committee also reviewed existing publicly available measure sets. These subsections serve as a synopsis of the revisions that were made to previous measures and a description of why the new measures were created for both the inpatient and outpatient settings. 3.1.1. Retired Measures The writing committee decided to retire the BP Control Measure because it was not concordant with the 2017 Hypertension Clinical Practice Guidelines.4 3.1.2. New Measures On the basis of the 2017 Hypertension Clinical Practice and the 2019 Prevention Guideline,14 the writing committee created a comprehensive list of mea- sures intended to be used to improve important gaps in the quality of care for patients with HBP.4,14 This set includes 22 new measures: 6 performance measures, 6 process quality measures, and 10 structural quality mea- sures. Table 8 includes a list of the measures with infor- mation on the attribution and a brief rationale.
