title: Just keep taking the tablets: adherence to antidepressant treatment in older people in primary care.
abstract: BACKGROUND
  poor adherence to antidepressant medication may account for a significant proportion of treatment failures. Adherence levels and factors associated with adherence have not previously been studied in older people.
  
  
  OBJECTIVE
  to report the prevalence and correlates of adherence to antidepressants in people > or = 65 years of age in a primary care setting.
  
  
  METHODS
  sixty-seven patients currently being prescribed antidepressants from a single rural general practice were assessed using a range of questionnaires measuring adherence to antidepressants, severity of depression, specific health education about antidepressants, level of side-effects, insight, positive and negatives beliefs about medication in general and antidepressants in particular, level of intellectual functioning (past and present), a past history of recovery from depression, type of antidepressant, complexity of prescriptions, age and living arrangements.
  
  
  RESULTS
  forty-five participants (67.2%) were fully adherent; seven (10.4%) mostly adherent, three (4.5%) adhered sometimes, three rarely and nine (13.4%) never. Backwards linear regression found that adherence increased with information given and cognitive impairment and decreased with concerns about taking antidepressants and severity of side-effects.
  
  
  CONCLUSIONS
  non-adherence to antidepressant medication is a significant problem in older patients. Our study probably overestimated adherence as it was self-report, which usually overestimates adherence and the refusals are more likely to have been people not taking tablets but still found nearly one third of the patients were non-adherent. An intervention comprising education, eliciting and addressing specific concerns about antidepressant medication and using medication, which minimises side effects, may be helpful.
