Even the best medicines in the world can be rendered ineffective if they are not taken as prescribed. The problem known as medication "non-adherence" is a major health issue in the United States, contributing to worse outcomes for people who have diabetes and other chronic diseases.
Now a study led by researchers at the University of California, San Francisco (UCSF), San Francisco General Hospital and Trauma Center (SFGH) and the Kaiser Permanente Division of Research has identified a significant factor that contributes to poor drug adherence - ineffective communication.
Described in the journal JAMA Internal Medicine, formerly known as the Archives of Internal Medicine, the study looked at 9,377 patients taking medications to lower their blood sugar, blood pressure or cholesterol.
These patients were asked through questionnaires to rate how well their doctors communicated with them. Patient medication adherence was determined by measuring delays in refilling prescriptions. The patients who gave their doctors poor marks in communicating were less likely to adhere to their medications.
The work suggests preparing doctors to be better communicators may help improve medication adherence and ultimately health outcomes, said lead author Neda Ratanawongsa, MD, MPH, an assistant professor in the UCSF Department of Medicine and the UCSF Center for Vulnerable Populations at SFGH.
