Objective: to compare the prescription of psychotropic medications for patients living in care homes with that for patients living at home.Design and setting: retrospective population database study in the Tayside region of Scotland.Subjects: 70,297 patients aged ≥65 and followed until death or the end of the study.Methods: examining registered addresses for all people aged 65-99 identified those in care. The prescriptions for a 12-week period was examined and psychotropic drug use compared by their place of residence. Comparisons of prescriptions pre- and post-admission were performed for people admitted to a care home from Jan 2005 to Dec 2006.Results: people living in care (4.1) received 9.80 more prescribed items (P < 0.001) from 1.63 more British National Formulary (BNF) categories (P < 0.001) than people living at home over a 12-week period. They were more likely to receive any psychotropic medication (42 versus 16, odds ratio (OR) 3.09, 95 CI: 2.79-3.41).Over 70 of 1,715 people admitted to care homes during the study who received psychotropic medication commenced the medication prior to admission. Patients who started anti-psychotics in the 30 days prior to admission were less likely to have stopped them (OR: 0.53, 95 CI: 0.30-0.94).Conclusion: prolonged prescription of psychotropic medications is commonplace in care home residents. Almost half of the people prescribed antipsychotic drugs received them for a minimum of 6 months. Systematic medication reviews must be established in all care homes to promote safe and effective prescription to this at-risk population.
