Abstract

BACKGROUND: Anemia among women of reproductive age has remained highly prevalent globally. Intravenous (IV) iron is well tolerated and proven effective for treating postpartum iron deficiency anemia in high-income countries, but evidence from LMICs, where oral iron is standard treatment, is limited. The PRIORITY trial will test the effectiveness of IV iron compared to oral iron for postpartum women with moderate anemia in eight LMIC sites. An implementation research (IR) study will be conducted alongside the PRIORITY trial in India and Pakistan to gather information on the intervention characteristics and the implementation process, and to assess feasibility, acceptability, fidelity, and cost of implementation for providing IV iron to postpartum women with moderate iron deficiency anemia.

METHODS: The PRIORITY IR study will use a mixed methods convergent parallel design guided by two frameworks: the Consolidated Framework for Implementation Research and Proctor's implementation outcomes. The IR study will be conducted in the Belagavi, India and Karachi, Pakistan PRIORITY trial sites. Participants will include postpartum women in the IV iron intervention arm of the trial, family members, health workers administering IV iron, hospital administrators, postpartum women who refuse to be part of the trial (Pakistan only), and postpartum women in the oral iron arm of the trial (India only). Data collection methods will include surveys, in-depth interviews, a supervision checklist, and a cost assessment. Survey and supervision checklist data will be analyzed descriptively. Interview data will be analyzed using a directed content analysis approach.

DISCUSSION: The PRIORITY IR study will contribute important information about implementation processes and strategies and feasibility, acceptability, fidelity, and costs for postpartum IV iron implementation. Results of the study can provide guidance for implementing effective anemia treatment in LMIC contexts with a high anemia burden.
