SUMMARY: Adequate vitamin D/calcium supplementation during osteoporosis (OP) treatments seems insufficient. This cohort study within a national claims database evaluated calcium/vitamin D co-prescription in postmenopausal women initiating an OP treatment. A high co-prescription rate was observed with three quarters of women supplemented with calcium and/or vitamin D in agreement with current recommendations. INTRODUCTION: Adequate calcium/vitamin D supplementation should be taken in combination with antiresorptive drugs in OP treatment. Despite guidelines, supplementation appears to be insufficient. The objective of this study was to describe and estimate co-prescription rates of calcium/vitamin D among postmenopausal women initiating an OP treatment. METHODS: All women over 50 years with a first claim for a bisphosphonates, raloxifene, or strontium prescription filled between May and August 2010 were included in a retrospective cohort study. Data source was the health insurance claims database of the Rhône-Alpes area. RESULTS: Among 4,415 women, 77.0 % had co-prescription of calcium or vitamin D with initial OP treatment, of which 2,150 (49.7 %) had both calcium and vitamin D. The proportion of women with calcium and/or vitamin D (81.7 %) was significantly higher when OP treatment was a bisphosphonate compared to strontium (70.9 %) or raloxifene (67.0 %) (p < 0.05). Among women prescribed both calcium and vitamin D, 7.6 % received a bisphosphonate and vitamin D ± calcium fixed-combination pack. General practitioners prescribed two thirds of initial supplementation treatment (66.9 %). Patients were twice as likely to be prescribed supplementation when the prescriber was a rheumatologist (OR = 2; 95 % CI = 1.57-2.54). CONCLUSION: Three quarters of women initiating OP treatment were supplemented with calcium and/or vitamin D in agreement with current recommendations. This represents a high co-prescription rate.
