Provider Perspectives on De-Implementation of Routine Blood Typing and Rh Immune Globulin Administration in the First...

Area of Science:

• Obstetrics and Gynecology
• Reproductive Health
• Implementation Science

Background:

• Historically, Rh immune globulin prophylaxis was standard for Rh-negative individuals with first-trimester bleeding to prevent Rh sensitization.
• Evolving research has led professional societies to update recommendations, yet clinical practice has lagged behind.
• Understanding physician perspectives is crucial for de-implementing outdated practices.

Purpose of the Study:

• To identify barriers faced by obstetrician-gynecologists in de-implementing routine Rh testing and Rh immune globulin prophylaxis for first-trimester bleeding.
• To gather insights on strategies that could facilitate the discontinuation of this practice.

Main Methods:

• Qualitative in-depth interviews were conducted with 20 obstetrician-gynecologists across diverse practice settings in 11 states.
• The Integrated Behavior Model and Consolidated Framework for Implementation Research guided the interview process.
• Thematic analysis was employed to identify barriers and facilitators for de-implementation.

Main Results:

• Key barriers included limited provider familiarity with current evidence and insufficient time for practice change initiatives.
• Physicians expressed a desire to de-implement the routine practice but cited a lack of adequate support systems.
• Drivers for change included updated professional society guidance, further research on first-trimester Rh sensitization, leadership endorsement, and provider/patient education.

Conclusions:

• Obstetrician-gynecologists are receptive to de-implementing routine Rh testing and prophylaxis in early pregnancy bleeding.
• Successful de-implementation requires enhanced provider confidence in evidence, strong institutional leadership support, and aligned professional society recommendations.
• Addressing knowledge gaps and providing educational resources are essential for practice transformation.
