Osteoporosis affects a large and growing proportion of the population. Multiple drugs for the prevention and treatment of osteoporosis have been developed, tested, and proven effective in the last decade. However, these drugs may not always be adequately prescribed. Several effective nonpharmacological measures also exist for preventing fractures; strength and gait training, home safety modifications, and other lifestyle modifications have all been shown in carefully conducted trails to reduce the risk of falls that lead to osteoporotic fractures. Yet these interventions are under-utilized. Practical public health strategies are needed to bring these experimental findings to widespread use in typical populations of at-risk patients. This study will evaluate innovative fracture prevention interventions targeted to both patients and doctors. Specifically, the study will compare the effects of the patient and physician behavior change intervention alone and in combination on prescribing patterns for osteoporosis therapies and will examine the interventions' effects on fracture prevention behaviors other than medication use.
