Patients ≥ 50 years of age and hospitalized for vertebral or hip fracture occurring from 01/01/2011 to 31/12/2015 were included. Patients were then classified as “untreated” and “treated” if they had been treated or not with drugs for fracture prevention after the index fracture. We also identified subjects that were only treated with drugs for fracture prevention, “osteoporosis drug only” group, compared to the “osteoporosis drug plus calcium/vitamin D” group, in which calcium and/or vitamin D were also in combination. Healthcare cost analysis included drug expenditure, hospitalization costs (excluding costs related to the hospitalization for the index fracture) and outpatient service costs.Results: Three thousand four hundred and seventy-five patients were included in the present study, most of whom (58.5%) had received specific osteoporosis treatment after index fracture. Among treated patients, the vast majority (83.6%) received supplementation with calcium/vitamin D. Mean annual healthcare cost per patient was € 9,289.85 in the untreated group and € 4,428.26 for treated subjects (p < 0.001); mean annual healthcare cost for the osteoporosis drug-only group was higher compared to the osteoporosis drug plus calcium/vitamin D group (€ 5,976.88 vs € 4,124.74, respectively, p < 0.001). Hospitalization costs accounted for the majority of total costs in all groups of patients.Conclusion: Healthcare costs in patients with osteoporotic fractures were significantly lower in those receiving osteoporosis treatment compared to untreated patients with even lower costs observed in patients that were also receiving calcium/vitamin D supplements.Keywords: healthcare costs, calcium/vitamin D supplementation, osteoporosis, fracture, hospitalization
