-Indicates that the ACC/AHA stage does not correspond to the measure. ACC indicates American College of Cardiology; AHA, American Heart Association; ASCVD, atherosclerotic cardiovascular disease; BP, blood pressure; COR, Class of Recommendation; e-health, healthcare services provided electronically via the Internet; EHR, electronic health record; HBP, high blood pressure; LOE, Level of Evidence; m-health, practice of medicine and public health supported by mobile devices; SM, structural measure; and USPSTF, US Preventive Services Task Force. 8 2.1. Literature Review In developing the updated HBP measure set, the writ- ing committee reviewed evidence-based guidelines and statements that would potentially impact the construc- tion of the measures. The clinical practice guidelines and scientific statements that most directly contributed to the development of these measures are shown in Table 6. 2.2. Definition and Selection of Measures In constructing the measure set, the writing committee recognized that other organizations (eg, CMS, NCQA) have developed or are continuing to develop HBP perfor- mance measures in response to the release of the 2017 Hypertension Clinical Practice Guidelines.4 Hence, the committee created performance measures for ACC/AHA stage 2 HBP that are aligned with these other groups, called harmonizing measures. In addition, the committee created enhancing measures that incorporate emerging evidence showing improved outcomes with more aggres- sive BP control (ie, for ACC/AHA stage 1 HBP). When defining harmonization, the writing committee followed the NQF Guidance for Measure Harmonization report, which states measure harmonization should be con- sidered when measures are intended to address either the same measure focus the target process, condition, event, outcome (eg, numerator) or the same target pop- ulation (eg, denominator).
