title: An observational study of psychotropic drug use and initiation in older patients resident in their own home or in care.
abstract: OBJECTIVE
  to compare the prescription of psychotropic medications for patients living in care homes with that for patients living at home.
  
  
  METHODS
  retrospective population database study in the Tayside region of Scotland.
  
  
  METHODS
  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).
  
  
  CONCLUSIONS
  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.
