title: Educational disparities in antipsychotic drug use among older people with and without dementia in Sweden.
abstract: OBJECTIVE
  Antipsychotic drugs are commonly used to treat behavioural and psychological symptoms of dementia. The aim was to investigate if socioeconomic position was associated with antipsychotic drug treatment among older adults with and without dementia.
  
  
  METHODS
  By record linkage of the Swedish Prescribed Drug Register, Patient Register, and Educational Register, we obtained information on antipsychotics, dementia status, and educational level for 641,566 persons aged 75-89 year old in Sweden 2005.
  
  
  RESULTS
  Among persons diagnosed with dementia (n = 32 092), 21% used antipsychotics compared with 4% in the total sample (n = 641,566). Lower education was associated with a higher probability of antipsychotic use in the total sample (adjusted odds ratio [OR] low vs. high education: 1.56; 95% confidence interval [CI]: 1.48-1.64). In the dementia subpopulation, lower education was also associated with a higher likelihood of use of antipsychotics (adjusted OR(low vs. high) 1.43; 95% CI: 1.28-1.59).
  
  
  CONCLUSIONS
  People with dementia were five times more likely to use antipsychotic drugs than the general population of older adults. Also, lower education was associated with a higher use of antipsychotics, both in the general population and in the subgroup of persons with dementia. This finding highlights the importance of investigating healthcare inequalities also among cognitively impaired older adults.
