Use of the EHR and patient registries is beneficial for guiding quality improvement efforts designed to improve hypertension control.S12.3.1-1 S12.3.1-3 Synopsis A growing number of health systems are developing or using registries and EHR that permit large-scale queries to sup- port population health management strategies to identify undiagnosed or undertreated hypertension. Such innovations are implemented as ongoing quality improvement initia- tives in clinical practice. To reduce undiagnosed hyperten- sion and improve hypertension management, a multipronged approach may include 1) application of hypertension screen- ing algorithms to EHR databases to identify at-risk patients, 2) contacting at-risk patients to schedule BP measurements, 3) monthly written feedback to clinicians about at-risk patients who have yet to complete a BP measurement, and 4) electronic prompts for BP measurements whenever at-risk patients visit Recommendation-Specific Supportive Text 1.
