Introducing a computerized cost containment module did not reduce drug expenses for general practitioners (GPs). More intensive cost containment strategies are needed beyond simple computer-assisted decision aids for GPs.

Area of Science:

  • Health Informatics
  • Pharmacoeconomics
  • General Practice

Background:

  • Computerized systems are increasingly used in healthcare for various functions.
  • Cost containment is a significant challenge in healthcare systems worldwide.
  • The role of technology in influencing prescribing behavior and drug expenditure requires investigation.

Purpose of the Study:

  • To evaluate the impact of a computerized cost containment module on prescribed drug doses and expenses among general practitioners (GPs).
  • To assess GPs' expectations and experiences with the implemented cost containment module.
  • To determine if computer assistance in selecting cheaper drugs affects overall drug expenditure.

Main Methods:

  • A controlled follow-up study analyzing prescribing data before and after module introduction.

  • Utilized data from the Health Insurance Aarhus County database for drug reimbursement.
  • Administered questionnaires to intervention group GPs regarding their expectations and experiences with the module.

    • Main Results:

    • No significant changes were observed in prescribed defined daily doses (DDD) or drug reimbursement costs in the intervention group compared to controls.
    • The introduction of the module did not lead to a reduction in reimbursement per prescribed DDD.
    • GPs were unaware of the ongoing cost supervision study during the intervention period.

    Conclusions:

    • Computer-assisted decision aids alone are insufficient for effective drug cost containment in general practice.
    • More intensive and comprehensive cost containment strategies are necessary to influence prescribing costs.
    • The study highlights the limitations of passive technological interventions in modifying physician prescribing behavior for cost savings.
