Patients prescribed diabetes, hypertension, and high cholesterol medications had higher levels of adherence than patients receiving care in other settings.
Patients in patient-centered medical homes are 2% to 3% more likely to take medicine as instructed that those in traditional practices, according to a new study in the Annals of Internal Medicine.
Researchers at Brigham and Women's Hospital and Harvard Medical School reviewed national claims data from the insurer Aetna, including patient-level claims for outpatient pharmacy prescription drug claims.
They compared patients enrolled in 3,533 medical homes to those treated at more than 50,000 control practices. All patients used medications for three chronic conditions—diabetes, hypertension and high cholesterol.
The study compared medication use for these patients to other patients in the same region by looking at the days covered by prescription claims for the same or similar medications.
The researchers found that patients seen at medical homes had levels of adherence that were an average of 2% to 3% higher than patients receiving care in other practices.
"In chronic conditions, such as hypertension, diabetes, and hyperlipidemia, medication adherence (the extent to which patients take their medications as prescribed) has become a growing concern for clinicians and payers," the researchers noted.
