A multi-dimensional intervention improved general practitioners' (GPs) prescription patterns, reducing drug costs without affecting patient care. Feedback and guidelines influenced prescribing, demonstrating successful practice change.

Area of Science:

  • Health Services Research
  • Pharmacoeconomics
  • General Practice

Background:

  • General practitioners' (GPs) prescription patterns significantly impact healthcare costs.
  • Optimizing prescription patterns is crucial for cost-effectiveness in primary and secondary care.
  • Interventions combining clinical guidelines and performance feedback may influence prescribing behavior.

Purpose of the Study:

  • To evaluate the impact of a multi-dimensional intervention on GPs' prescription patterns.
  • To assess changes in prescription patterns across five Anatomical Therapeutic Chemical (ATC) groups.
  • To determine if the intervention influenced drug costs and potential savings.

Main Methods:

  • Prospective historical registry study analyzing prescription data.

  • Questionnaire study assessing GPs' self-reported use of guidelines and feedback.
  • Analysis of defined daily doses (DDD) and cost per DDD before and after the intervention.

    • Main Results:

    • Prescribed DDD increased, but cost per DDD decreased across all ATC groups post-intervention.
    • Practices with higher initial potential savings showed greater reductions.
    • County average cost per DDD fell below the national average.
    • 78% of GPs reported that feedback influenced their prescribing.

    Conclusions:

    • The intervention successfully altered GPs' prescription patterns, leading to cost savings.
    • Changes were driven by price effects (generic substitution, cheaper analogues), not volume.
    • It is feasible to modify prescribing habits without compromising patient access or clinical autonomy.
