Burden of First Osteoporotic Hip Fracture in Spain: A Prospective, 12-Month, Observational Study.

ABSTRACT

The purpose of this study was to estimate the burden of osteoporotic fractures beyond the hospitalization period covering up to the first year after the fracture. This was a prospective, 12-month, observational study including patients aged ≥65 years hospitalized due to a first low-trauma hip fracture, in six Spanish regions. Health resource utilization (HRU), quality of life (QoL) and autonomy were collected and total costs calculated. Four hundred and eighty seven patients (mean ± SD age 83 ± 7 years, 77 % women) were included. Twenty-two percent of patients reported a prior non-hip low-trauma fracture, 16 % were receiving osteoporotic treatment at baseline, and 3 % had densitometry performed (1.8 % T-score ≤-2.5). Sixteen percent of patients died (women 14 %; men 25 %; p = 0.0011) during the first year. Mean hospital stay was 11.8 ± 7.9 days and 95.1 % of patients underwent surgery. Other relevant HRUs were outpatient visits in 78 % of patients (mean 9.2 ± 9.7); walking aids, 58.7 %; rehabilitation facilities, 35.5 % (28.7 ± 41.2 sessions); and formal and informal home care, 22.2 % (49.6 ± 72.2 days) and 53.4 % (77.1 ± 101.0 h), respectively. Mean direct cost was €9690 (95 % confidence interval 9184-10,197) in women and €9019 (8079-9958) in men. Main cost drivers were first hospitalization episode (women €7067 [73 %]; men €7196 [80 %]); outpatient visits (€1323 [14 %]; €997 [11 %]); and home care (€905 [9 %]; €767 [9 %]). QoL and autonomy showed a marked decrease during hospitalization, not entirely recovered at 12 months (p < 0.05 vs. baseline for EQ-5D, Harris hip score and modified Barthel index). In a Spanish setting, osteoporotic hip fractures incur a high societal and economic cost, mainly due to the first hospitalization HRU, but also due to subsequent outpatient visits and home care.
