Abstract
OBJECTIVE: To determine whether 3-monthly supplementation of an oral vitamin D widely used in Spain (calcifediol) plus daily exercise could influence survival at one and four years after surgery for osteoporotic hip fracture. DESIGN: A pragmatic, randomized, partially single-blind placebo-controlled study. SETTING:Patients admitted to a tertiary university hospital for acute hip fracture. PARTICIPANTS: 675 healthy adult patients undergoing surgery for osteoporotic hip fracture were recruited from January 2004 to December 2007. INTERVENTION: Patients were randomized to receive either 3-monthly oral doses of 3 mg calcifediol (Hidroferol Choque®) or placebo in the 12 months postsurgery. Patients who received calcifediol were also given an exercise programme. The placebo group received standard health recommendations only. MEASUREMENTS: The primary endpoint was survival at 1 year and at 4 year follow-up. We also recorded new fractures, medical complications and anti-osteoporotic treatment compliance. RESULTS: We included a total of 88 patients, aged 62 to 99 years. Mean age was 82 years and 88.6% were women. At 12 months, 10 (11.3%) patients had died, 9 of them, from the non-intervention group. At 4 years after surgery, 20 (22.7%) had died, 3 (3.4%) from the intervention group and 17 (19.3%) from the non-intervention group. At this time, survival curve analysis showed 93% survival in the intervention group and 62% in the non-intervention group (p=0.001). At 12-month follow up, there were 18 new fractures, 9 in each group. The non-intervention group had more medical complications, with significant differences at visit 2 (p = 0.04) and 3 (p = 0.02) but not at visit 4 (p = 0.18). No significant differences between groups were found regarding treatment compliance. CONCLUSION: 3-monthly, oral supplements of 3 mg calcifediol plus daily exercise improved survival at one-year and four-year follow up after surgery for an osteoporotic hip fracture.
