(HealthDay News) – For patients with uncontrolled blood pressure (BP), use of a telemonitoring intervention involving home BP telemonitors and pharmacist case management is associated with greater improvements in BP control than those seen with usual care, according to a study published in the July 3 issue of the Journal of the American Medical Association.
Karen L. Margolis, MD, MPH, from the HealthPartners Institute for Education and Research in Minneapolis, and colleagues conducted a cluster randomized trial involving 450 adults with uncontrolled BP recruited from 16 primary care clinics to compare an intervention combining home BP telemonitoring with pharmacist case management (228 patients) with usual care (222 patients). The intervention, which provided patients with home BP telemonitors and transmitted data to pharmacists who adjusted medications accordingly, lasted 12 months, and post-intervention follow-up was continued for six months.
The researchers found that, compared with the usual-care group, the proportion of patients with BP control at both six and 12 months was significantly greater in the telemonitoring group (57.2% vs. 30%). The proportion with BP control at 18 months was also significantly higher in the telemonitoring group (71.8% vs. 57.1%). For patients in the telemonitoring group, the decrease in systolic BP from baseline to six and 12 months was significantly greater than that seen in the usual-care group.
“Home BP telemonitoring and pharmacist case management achieved better BP control compared with usual care during 12 months of intervention that persisted during six months of post-intervention follow-up,” the authors write.
