Background: Osteoporosis is inadequately treated in primary care settings. Under-recognition of the condition among male Veterans may contribute to this problem. In order to improve understanding of bone health in older male patients, we developed the "Musculoskeletal (MSK) Education Week", a multidisciplinary clinical training initiative within a primary care ambulatory rotation for internal medicine (IM) residents at the Salt Lake City VA Medical Center. The objective of this study was to evaluate the impact of this program on trainees' recognition of osteoporosis or treatment of this condition following the training experience.
Methods: We examined several clinical behaviors of post-graduate year 1 (PGY-1) IM trainees following their participation in the MSK Education Week between July 1-April 30, 2014. To determine the prevalence of these clinical behaviors, we conducted an observational study of patients age 50 and older enrolled at the Salt Lake City VA Healthcare System from July 1, 2013 to May 31, 2014. We used time-dependent multivariable Cox proportional hazard models to evaluate the impact of the training program on 4 osteoporosis-related outcomes: (1) completion of dual energy X-ray absorptiometry (DXA) scan, (2) diagnosis of osteopenia, (3) diagnosis of osteoporosis, and (4) initiation of osteoporosis medications.
Results: Twenty-six PGY-1 IM residents participated in the MSK Education Week, and 43,678 Veterans were identified over these periods of observation. In the Veterans cohort, 1154 had an encounter with a provider who had completed the training (and were therefore "exposed" to the training) and 42,524 Veterans did not. After adjusting for confounders, the effect of the provider training program was significant for DXA (HR = 1.78, 95% CI: 1.11, 2.87), osteoporosis diagnosis (HR = 3.90, 95% CI: 2.09, 7.29), and initiation of medications (HR = 2.87, 95% CI: 2.02, 4.09) outcomes.
Conclusions: We have shown that IM residents' participation in the MSK Education Week was associated with significantly improvements in their completion of DXA scans, diagnosis of osteoporosis, and initiation of fracture-reducing medications in a population of US Veterans. Long-term follow up is needed to determine whether these initial results are followed by actual reductions in osteoporotic fractures.
