(HealthDay News) – Use of a telephone-based motivational interviewing intervention does not improve adherence to an osteoporosis medication regimen, according to research published online Feb. 27 in the Archives of Internal Medicine.

Daniel H. Solomon, MD, MPH, of Brigham and Women’s Hospital in Boston, and colleagues conducted a one-year randomized, controlled trial involving more than 2,000 patients recently prescribed osteoporosis medication. Half of the patients (1,046 participants) were randomly allocated to receive telephone-based counseling using a motivational interviewing framework, while the other half (1,041 participants) served as the control group and received mailed educational materials.

In this predominantly female patient population with an average age of 78 years, the researchers found that the median adherence rate was 49% in the intervention group and 41% in the control group (P=0.07). Additionally, there was no between-group difference in the number of self-reported fractures.

“In this randomized controlled trial, we did not find a statistically significant improvement in adherence to an osteoporosis medication regimen using a telephonic motivational interviewing intervention,” the authors write.

Several authors disclosed financial ties to the pharmaceutical and health care industries.
