Physician education initially reduced Coumadin (blood thinner) overdosing and complications. However, gains were not sustained, highlighting the need for ongoing pharmacy review and further education to maintain patient safety.

Area of Science:

  • Clinical Pharmacy
  • Patient Safety
  • Quality Improvement

Background:

  • Continuous Quality Improvement (CQI) identified excessive Coumadin dosing leading to adverse events.
  • Physician education was implemented as an intervention to address the issue.

Purpose of the Study:

  • To assess the impact of physician education on reducing Coumadin overdosing and associated complications.
  • To evaluate the sustainability of quality improvement interventions over time.

Main Methods:

  • Utilized the FOCUS PDCA (Plan-Do-Check-Act) methodology for continuous quality improvement.
  • Intervention involved educating physicians on appropriate Coumadin dosing protocols.
  • Data reviewed at baseline, post-intervention, and one year later.

Main Results:

  • Initial physician education significantly reduced instances of Coumadin overdosing and complications.
  • Observed benefits diminished over the one-year follow-up period, indicating a lack of sustained improvement.
  • Study limitations include a small patient cohort and limited post-intervention time points.

Conclusions:

  • Physician education is effective in the short-term for improving Coumadin dosing safety.
  • Sustained improvements require regular multidisciplinary review (Pharmacy and Laboratory) and ongoing physician education.
  • The FOCUS PDCA framework provided valuable experience in implementing quality improvement initiatives.
