Abstract

Hypertension is an important modifiable risk factor for cardiovascular disease in patients with diabetes. Despite established guidelines, the percentage of patients meeting the target blood pressure (BP) of <140/90 mm Hg in clinic remains suboptimal. In this project, we sought to improve BP measurement in an outpatient diabetes clinic.

Two interventions were performed: (1) Changes were made to the timing of BP measurement during patient intake and (2) An electronic medical record (EMR) alert reminded staff to repeat BP if the initial reading was above target. Baseline data were collected on 4764 patients, with 72.5% meeting their BP target. After implementation of changes to the timing of BP measurement during patient intake, 73.3% of patients met the target (no significant change). However, after implementation of the EMR alert, there was a statistically significant improvement in patients meeting the target BP at 76.8% (p<0.01). This reduction was driven by the high percentage of patients with an initially elevated BP measurement that came down into goal range on repeat measurement. Those who remained above target despite multiple readings could be referred to a new pharmacist-led hypertension clinic to ensure adequate follow-up and medication adjustment.

It is important to ensure that in clinic BP measurements are taken correctly and adhere to best practices. Use of a single in-clinic BP measurement may result in overtreatment of hypertension. While timing of BP measurement during patient intake was not important, repeating high BP measurements did improve the number of patients in an outpatient diabetes clinic meeting their BP target.
