title: [Evaluating, improving and monitoring generic drug prescription].
abstract: OBJECTIVE
  To evaluate and improve generic drug prescription by family physicians in a regional primary care district with a specially-designed intervention.
  
  
  METHODS
  Uncontrolled study of an intervention, based quality evaluation and improvement methods. We selected an indicator that could be constructed with the available data (monthly reports of prescriptions dispensed through the public national health system) and determined the proportion of prescriptions for generic drugs to the total number of prescriptions dispensed, for those medications that had a generic alternative (percentage of generic prescriptions, PGP). After these data were evaluated, an intervention was implemented to increase generic prescriptions. Prescribing behavior was again evaluated and monitored at the end of the intervention period. Setting. Forty-five primary care teams in the Murcia (Southeast Spain) regional primary care district.
  
  
  METHODS
  A total of 339 family physicians. Interventions. During 15 months, individual reports of prescribing practices, in which changes over time were graphed, were sent to each participating prescriber. Each semester the physicians received a personal letter and a specially-printed, updated card showing the generic medications available and their pharmaceutical forms. One to three face-to-face clinical outreach sessions were held with each primary care team. Specific prescribing goals for the PGP were set and incentives to attain the goals were included in the terms of the contract for clinical services signed between the regional office of primary care management and each primary care team.
  
  
  METHODS
  The PGP increased from a pre-intervention rate of 2.7% to a post-intervention rate of 17.63%. Absolute improvement was therefore 14.84%, and relative improvement was 15.27%. Variability was monitored and analyzed with control charts. There was no significant variability within the pre- and post-intervention phases, whereas variability increased significantly (indicating improvement) during the intervention phase.
  
  
  CONCLUSIONS
  The increase in PGP showed that prescribing for generic preparations improved. Statistical quality control tests were useful in evaluating and tracking the results of the intervention, and were indispensable for monitoring and promptly detecting opportunities to improve prescribing behavior and take appropriate measures.
