title: Trends in inappropriate drug therapy prescription in the elderly in Sweden from 2006 to 2013: assessment using national indicators.
abstract: BACKGROUND
  Medication for elderly patients is often complex and problematic. Several criteria for classifying inappropriate prescribing exist. In 2010, the Swedish National Board of Health and Welfare published the document "Indicators of appropriate drug therapy in the elderly" as a guideline for improving prescribing for the elderly.
  
  
  OBJECTIVE
  The aim of this study was to assess trends in the prescription of inappropriate drug therapy in the elderly in Sweden from 2006 to 2013 using national quality indicators for drug treatment.
  
  
  METHODS
  Individual-based data on dispensed prescription drugs for the entire Swedish population aged ≥65 years during eight 3-month periods from 2006 to 2013 were accumulated. The data were extracted from the Swedish Prescribed Drug Register. Eight drug-specific quality indicators were monitored.
  
  
  RESULTS
  For the entire population studied (n = 1,828,283 in 2013), six of the eight indicators showed an improvement according to the guidelines; the remaining two indicators (drugs with anticholinergic effects and excessive polypharmacy) remained relatively unchanged. For the subgroup aged 65-74 years, three indicators showed an improvement, four indicators remained relatively unchanged (e.g. propiomazine, and oxazepam) and one showed an undesirable trend (anticholinergic drugs) according to guidelines. For the older group (aged ≥75 years), all indicators except excessive polypharmacy showed improvement.
  
  
  CONCLUSIONS
  According to the quality indicators used, the extent of inappropriate drug therapy in the elderly decreased from 2006 to 2013 in Sweden. Thus, prescribers appear to be more likely to change their prescribing patterns for the elderly than previously assumed.
