An intervention including home BP telemonitoring plus nurse case management lowered BP more than home BP telemonitoring alone in minority stroke survivors, according to findings presented at the International Stroke Conference.

“Blacks and Hispanics have poorer stroke outcomes than Caucasians. Hypertension is a major predictor of racial disparities in stroke outcomes in the United States,” Gbenga Ogedegbe, MD, MPH, FACP, Dr. Adolph and Margaret Berger Professor of Medicine at NYU Grossman School of Medicine, said during a presentation. “Hypertension control in stroke survivors is key to secondary stroke prevention. Home BP telemonitoring and nurse case management have proven efficacy in addressing multilevel barriers to hypertension control. However, their effectiveness remains untested in stroke patients, and their implementation is suboptimal in blacks and Hispanics.”

Ogedegbe and colleagues randomly assigned 450 black and Hispanic stroke survivors (mean age, 62 years; 44% women; 51% black; 72% with annual family income less than $25,000) to home BP telemonitoring alone that consisted of home BP readings 3 days per week for 12 months — each of which were wirelessly transmitted to a secure server — plus BP reports sent to patients and physicians for 12 months, or to home BP telemonitoring plus nurse case management that consisted of 20 counseling calls with a nurse who reviewed the BP reports and offered lifestyle counseling.

All patients had systolic BP of at least 140 mm Hg on two readings prior to randomization.

Systolic BP declined in both groups at 6 and 12 months (P < .0001 for all), but the between-group difference favored the intervention group (6-month estimate, –7.32 mm Hg; standard error, 1.72; P < .0001; 12-month estimate, –9.24 mm Hg; standard error, 1.75; P < .0001), Ogedegbe said during his presentation.

Within-group systolic BP change was –6.31 mm Hg at 6 months and –5.52 mm Hg at 12 months in the control group and –13.62 mm Hg at 6 months and –14.76 mm Hg at 12 months in the intervention group (P < .05 for all), he said.

“These findings present strong empirical evidence for widespread implementation in low-income minority stroke survivors with multiple comorbidities,” Ogedegbe said during the presentation. “Policymakers and health care plans now have the needed evidence to implement these plans in minority patients with stroke and uncontrolled hypertension. Effectiveness of this intervention in secondary stroke prevention warrants further investigation.” – by Erik Swain
