WEDNESDAY, Nov. 16, 2016 (HealthDay News) -- Medication adherence is increased with receipt of care in a patient-centered medical home, according to a study published online Nov. 15 in the Annals of Internal Medicine.

Julie C. Lauffenburger, Pharm.D., Ph.D., from Brigham and Women's Hospital in Boston, and colleagues examined the correlation between medication adherence and medical homes in a national patient and provider population using data from a retrospective cohort study. In the 12 months after treatment initiation, medication adherence was compared among patients cared for by providers practicing in National Committee for Quality Assurance-recognized patient-centered medical homes and propensity score-matched control practices. Data were included for 313,765 patients, of whom 18,611 (5.9 percent) received care in patient-centered medical homes.

The researchers found that the mean rates of adherence were 64 and 59 percent, respectively, among medical home and control patients. Among 4,660 matched control and medical home practices, medical homes had significantly higher medication adherence (adjusted mean difference in adherence, 2.2 percent). The correlation between medical homes and better adherence did not vary significantly with disease state (adjusted mean difference in adherence, 3.0, 3.2, and 1.5 percent, respectively, for diabetes, hypertension, and hyperlipidemia).

"Receipt of care in a patient-centered medical home is associated with better adherence, a vital measure of health care quality, among patients initiating treatment with medications for common high-cost chronic diseases," the authors write.

The study was funded by CVS Health; several authors disclosed financial ties to CVS Health and the pharmaceutical industry.
