Background
In cross-sectional studies, patient activation has been associated with better health behaviors, health outcomes, and health care experiences. Moreover, tailored interventions have led to clinically meaningful improvements in patient activation, as well as health outcomes over time. We tested whether a tailored patient-activation letter communicating bone mineral density (BMD) test results plus an educational brochure improved patient activation scores and levels at 12- and 52-weeks post-baseline as the mechanism leading to enhanced bone healthcare.
Methodology
In a randomized, controlled, double-blinded, multi-center pragmatic clinical trial we randomized 7,749 patients ≥ 50 years old and presenting for BMD testing at three medical centers in the United States between February 2012 and August 2014. The outcome measures were patient activation scores and levels based on six-items taken from the Patient Activation Measure (PAM) that were administered at the baseline, 12-week, and 52-week follow-up interviews.
Results
Mean age was 66.6 years, 83.8% were women, and 75.3% were Non-Hispanic-Whites. Overall, PAM activation scores improved from 58.1 at baseline to 76.4 by 12-weeks (p < 0.001) and to 77.2 (p = 0.002) by 52-weeks post-baseline. These improvements, however, were not significantly different between the intervention and usual care groups (18.7 vs. 18.1, p = 0.176, at 12-weeks) in intention-to-treat analyses.
Conclusion
PAM activation scores and levels substantially improved at 12-weeks and 52-weeks, but no differences were observed in these improvements between the intervention and usual care groups. These null findings may have occurred because the tailoring focused on the patient’s BMD and fracture risk results, rather than on the patient’s BMD and fracture risk results as well as the patient’s baseline PAM activation scores or levels.
