Abstract
OBJECTIVE
To determine whether an emergency department (ED) education and empowerment intervention coupled with early risk assessment can help improve blood pressure (BP) in a high-risk population.
METHODS
A hypertension emergency department intervention aimed at decreasing disparities (AHEAD2) is a 3-arm, single-site randomized pilot trial for feasibility in an urban academic ED. A total of 150 predominantly ethnic minorities with no primary care provider and severely elevated blood pressure (BP) (≥160/100 mm Hg) were enrolled over 10 months. Participants were randomized into 1 of 3 study arms: (1) enhanced usual care (EUC), (2) ED-initiated screening, brief intervention, and referral for treatment (ED-SBIRT), or (3) ED- SBIRT plus a 48-72 hours post-acute care hypertension transition clinic (ED-SBIRT+PACHT-c). Primary outcomes were change in systolic and diastolic BP (SBP and DBP) from baseline to 9 months. Secondary outcomes were BP control (BP <140/90 mm Hg), changes in hypertension knowledge, medication adherence, and limited bedside echocardiogram (LBE) findings.
RESULTS
SBP reduction from baseline to month 9 was -26.8 (95% confidence interval [CI]: -32.8, -20.7) mm Hg for ED-SBIRT, -23.4 (95% CI: -29.5, -17.3) mm Hg for ED-SBIRT+PACHT-c, and -18.9 (95% CI: -24.9, -12.9) mm Hg for EUC. DBP decreased by -12.5 (95% CI: -16.1, -9.0) mm Hg for ED-SBIRT, -11.3 (95% CI: -14.8, -7.7) mm Hg for ED-SBIRT+PACHT-c, and -8.4 (95% CI: -11.9, -4.9) mm Hg for EUC. A multicomponent intervention compared with EUC resulted in SBP decrease of -7.9 mm Hg (95% CI: -16.4, 0.6). At 9 months, hypertension was controlled for 29.3% (95% CI: 20.3, 38.3) of intervention and 23.5% (95% CI: 11.9, 35.2) of EUC participants. All groups saw improvements in hypertension knowledge, medication adherence, and LBEs, with greater improvements in intervention groups.
CONCLUSIONS
The study findings suggest that a multicomponent intervention comprising of ED education and empowerment coupled with early risk assessment may help improve BP in a high-risk population.
