Psychoactive medicine use and the risk of hip fracture in older people: a case‐crossover study

Many factors can increase the risk of hip fracture, including medicines. Traditional observational studies have assessed the risk, but results may be confounded by unmeasured factors. The case‐crossover design is an alternative approach that controls for patient‐specific, time‐invariant confounding factors. This study aimed to assess associations between psychoactive medicines and hip fracture in the elderly using the case‐crossover method.
