title: A randomized controlled trial comparing two ways of providing evidence-based drug information to GPs.
abstract: OBJECTIVE
  To investigate whether tailored evidence-based drug information (EBDI) to general practitioners (GPs) can change the proportion of ACE inhibitor prescriptions more effectively than EBDI provided as usual three and six months after the intervention.
  
  
  METHODS
  Randomized controlled trial.
  
  
  METHODS
  GPs in southern Sweden working at primary health care centres (PHCCs) in seven drug and therapeutic committee areas.
  
  
  METHODS
  EBDI tailored to motivational interviewing (MI) technique and focused on the benefit aspect was compared with EBDI provided as usual.
  
  
  METHODS
  There were 408 GPs in the intervention group and 583 GPs in the control group.
  
  
  METHODS
  Change in proportion of ACE inhibitor prescriptions relative to the sum of ACE inhibitors and angiotensin receptor blockers, three and six months after the intervention.
  
  
  RESULTS
  The GPs' average proportions of prescribed ACE inhibitors increased in both groups. No statistically significant differences in the change of proportions were found between intervention and control groups. Information was provided to 29% of GPs in both groups.
  
  
  CONCLUSIONS
  This study could not prove that specially tailored EBDI using MI implements guidelines more effectively than EBDI provided as usual.
