Cochrane Systematic Review • 38 trials • Vit D vs. placebo/no treatment • No evidence for annual injection of vit D in preventing hip or other osteoporotic fractures • No evidence for oral vit D either as a 4-monthly bolus dose of 100,000 IU or daily doses up to 830 IU • Further studies indicated with doses of ≥800 IU daily in very high risk populations with low sunlight exposure, such as people in nursing homes Avenell A, Gillespie WJ, Gillespie LD, O'Connell DL.

Vit D + calcium vs. placebo/no treatment • 700-800 IU vit D3 + 1000 mg calcium reduces the incidence of hip fractures and all non-vertebral fractures • Statistically significant effect seen in pooled data from institutionalised participants, but not in those living in the community. • No evidence that people with a prior fracture history, irrespective of age, benefit in respect of hip fracture incidence from vitamin D and calcium • Alfacalcidol • 3 small trials, same author, evidence inconclusive • Calcitriol • Benefit unclear, increased risk of hypercalcaemia
SIGN Guidelines • In frail, elderly women (aged 80+ years) with a diagnosis of osteoporosis, with or without previous osteoporotic fractures • To reduce hip fracture risk, frail elderly women who are housebound should receive oral calcium (1000-1200 IU daily + 800 IU Vitamin D)
