    ObjectiveTo evaluate the incidence of hip fracture in patients with antipsychotic treatment, comparing it with that of individuals who have not been treated with antipsychotics.DesignRetrospective cohort study of patients treated with antipsychotic drugs (TAP) and patients without known treatment (non-TAP). The observation period was 2006-2014. SITE: All primary care teams in Catalonia of the Catalan Health Institute (ICS).ParticipantsPatients older than 44 years with TAP lasting at least 3 months. Control cohort: random selection of non-TAP patients matching for baseline comorbidities and other variables. A total of 22,010 are analyzed. Main measurements Incidence rate (1000× person-years: PY) of hip fracture in each group (TAP and non-TAP). Cox regression models to estimate adjusted risks (hazard ratio: HR).ResultsThe hip fracture incidence rate was higher in TAP patients (5.83 vs 3.58 fractures per 1000 PY), and is higher in all strata according to sex, age and type of diagnosis. The risk of suffering a hip fracture was 60% higher (HR: 1.60 95% CI: 1.34-1.92) in the TAP group than in the non-TAP group. The risk was higher in the group with schizophrenia (HR: 3.57 95% CI: 1.75-7.30), followed by bipolar disorder (HR: 2.61; 95% CI: 1.39-4.92) and depression (HR: 1.51; 95% CI: 1.21-1.88).ConclusionsPatients with antipsychotic treatment have a higher risk of hip fracture than those who have not been treated with antipsychotics.Copyright © 2021 The Authors.
