Résumé :

Objective: The present report assesses, among Belgian gynecologists, the effect of age and bone mineral density on osteoporosis prescription strategy in postmenopausal women. Methods: Charts of postmenopausal women were summarized. We constructed cases by modifying some parameters. Ten years of age were added or subtracted to the real age of the patient. The bone mineral density (BMD) result was also modified (three levels: normal BMD, osteopenia, osteoporosis). A total of 612 cases were constructed. Twelve cases were sent out of these 612 files to every Belgian gynecologist (n=1010). For each chart the gynecologists were asked whether they would treat the patient with HRT. They were also asked whether they would prescribe other therapies than HRT and if so, which ones. Results: The chance to have an osteoporosis prevention or treatment prescribed increased when BMD decreased (respectively 57.4% for normal BMD, 73.1% for osteopenia cases and 89.4% for osteoporosis cases; P<0.001). HRT was the most frequently prescribed medication (67% of the cases), but its prescription rate does not reflect only osteoporosis prevention. Nevertheless, for similar cases with osteopenia, the HRT prescription rate increased by a factor 1.25 and for similar cases with osteoporosis, HRT prescription rate increased by a factor 1.39. Calcium was the 2nd most frequent prescribed regimen. It was prescribed in 17% of the cases. A 3.4-fold increase for osteopenia cases and 7.6-fold increase for osteoporosis cases was observed, compared to women with normal BMD. When calcium was prescribed, it was in association with HRT in 64% of the osteopenia cases and in 76% of osteoporosis cases. Other drugs were less often prescribed. For the 'younger age group', that is, with a mean age of 55 years, a prescription rate of 82.9% for any osteoporosis regimen was reached, whereas in the age group that was 10 years older a 20% lower prescription rate was reached (62.6%, P<0.001). This was mostly due to a decrease in HRT prescription. Conclusions: Prescription of medication known to reduce osteoporosis occurred more often in cases with low BMD. In the older patients with osteoporosis, gynecologists prescribed HRT less frequently. This was not compensated by a higher prescription rate of other medication.
