RESUMO
BACKGROUND: Despite the availability of effective preventive and curative medications for osteoporosis, and guidelines for its diagnosis and management, few individuals are treated for osteoporosis, even among those who have already had a fracture. OBJECTIVES: Our objective was to describe the patterns of use of medication for osteoporosis, i.e., calcium supplements, vitamin D supplements, and specific anti-osteoporotic drugs, such as bisphosphonates, in a large sample of French older women living at home, and to identify individual factors associated with use of these medications overall and in two specific clinical situations. METHODS: Cross-sectional analysis of data from 4,221 women aged 75-85 years who participated in a balance and mobility examination as part of the screening procedure for the Ossébo study, a randomized controlled trial testing the effectiveness of exercise for the prevention of fall-related injuries. Electoral rolls were used to invite women in 16 towns to participate (participation rate 10.3 %). Information collected through questionnaires included current medication use and, in particular, use of osteoporosis medications (specific osteoporosis drugs, calcium and vitamin D supplementation) in the past 6 months, and history of fracture since the age of 50, including fracture locations. Fractures were categorized in three groups: no fracture, major osteoporotic fracture (hip, humerus, wrist, pelvis, and vertebra), and other fracture. RESULTS: Nearly 48 % of the participants reported they did not take calcium or vitamin D supplements or any specific osteoporosis drugs. Of the 2,133 women who reported using osteoporosis medication, 85 % used vitamin D supplements (25 % as the sole medication against this disease), 59 % calcium supplements, and 42 % a specific anti-osteoporotic drug (75 % of them combining it with vitamin D supplementation). The use of any osteoporosis medication was significantly associated (p < 0.001) with a history of a major osteoporotic fracture, lower weight, dual-energy X-ray absorptiometry (DXA) bone-density measurement in the past 5 years, a cancer-screening examination in the past 5 years, and a positive attitude toward medication use in general. Living alone was associated with a lower likelihood of using a specific anti-osteoporotic drug, and a higher education level was associated with a higher likelihood of vitamin D supplementation. Of the 1,553 women who had already had a major osteoporotic fracture, one-third (34.8 %) were not taking any osteoporosis medication. In this subgroup, use of this medication was associated with the same factors as in the overall study population. In particular, neither older age nor a history of falls in the previous 12 months was associated with a higher likelihood of using osteoporosis medication. Among the 909 women who reported using a specific osteoporosis drug, vitamin D use was associated with a higher educational level and a more frequent preventive attitude. CONCLUSION: In France, as in other western countries, women aged 75 years and over are not managed according to guidelines. Further studies should address the barriers encountered in improving quality of care in osteoporosis management.

Despite strong evidence for the efficacy of integrated systems, securing the participation of health professionals, particularly primary care physicians (PCPs), has proven difficult. Novel approaches are needed to resolve these problems. We developed a model - COPA - that is based on scientific evidence and an original design process in which health professionals, including PCPs, and managers participated actively. COPA targets very frail community-dwelling elders recruited through their PCP. It was designed to provide a better fit between the services provided and the needs of the elderly in order to reduce excess healthcare use, including unnecessary emergency room (ER) visits and hospitalizations, and prevent inappropriate long-term nursing home placements. The model's originality lies in: 1) having reinforced the role played by the PCP, which includes patient recruitment and care plan development; 2) having integrated health professionals into a multidisciplinary primary care team that includes case managers who collaborate closely with the PCP to perform a geriatric assessment (InterRAI MDS-HC) and implement care management programs; and 3) having integrated primary medical care and specialized care by introducing geriatricians into the community to see patients in their homes and organize direct hospitalizations while maintaining the PCP responsibility for medical decisions. Since COPA is currently the subject of both a quasi-experimental study and a qualitative study, we are also providing preliminary findings. These findings suggest that the model is feasible and well accepted by PCPs and patients. Moreover, our results indicate that the level of service utilization in COPA was less than what is reported at the national level, without any compromises in quality of care.
