Randomized controlled trials (RCTs) can effectively study continuous quality improvement (CQI) when viewed as a model for generating interventions. Designing these RCTs requires careful consideration of randomization units and intervention flexibility.

Area of Science:

  • Healthcare Management
  • Quality Improvement Science
  • Clinical Trial Design

Background:

  • Continuous quality improvement (CQI) is widely adopted in healthcare, but rigorous evaluation using randomized controlled trials (RCTs) is infrequent.
  • The application of CQI spans general management philosophy and specific intervention development.

Purpose of the Study:

  • To explore the feasibility, timing, and methodology for designing RCTs of CQI.
  • To differentiate between studying CQI as a broad philosophy versus a model for intervention generation.

Main Methods:

  • Conceptual analysis of CQI applications in healthcare settings.
  • Illustrative example using warfarin therapy for stroke prevention in atrial fibrillation patients.

Main Results:

  • RCTs are impractical for evaluating CQI as a general management philosophy.
  • RCT methodology is suitable for assessing CQI as a framework for developing specific interventions.
  • Key design considerations for CQI RCTs include the unit of randomization, focus (method vs. intervention), and intervention adaptability.

Conclusions:

  • Randomized controlled trials (RCTs) are feasible for evaluating continuous quality improvement (CQI) when it serves as a conceptual model for generating interventions.
