“The finding of higher blood pressure among the group that received EHR tools alone was unexpected,” Stephen D. Persell, MD, MPH, and colleagues wrote in JAMA Internal Medicine. “We speculate that medication information sheets (which contain some information on adverse drug effects) may have led some patients to stop or reduce antihypertensive therapy.”
All patients included in the study had hypertension, spoke English, were taking at least three medications for any purpose and were responsible for administering their own medications. A total of 794 patients completed the 12-month follow-up visit. Most participants were black (87.2 percent), used Medicaid insurance (51.1 percent) and 68.6 percent were women.
