BACKGROUND: Evidence for the management of moderate-to-severe postpartum anemia is limited. A randomized trial is needed; recruitment may be challenging.
STUDY DESIGN AND METHODS: Randomized pilot trial with feasibility surveys.
INCLUSION: hemoglobin 65-79 g/L, ≤7 days of birth, hemodynamically stable.
EXCLUSION: ongoing heavy bleeding; already received, or contraindication to intravenous (IV)-iron or red blood cell transfusion (RBC-T). Intervention/control: IV-iron; RBC-T; or IV-iron and RBC-T.
PRIMARY OUTCOME: number of recruits; proportion of those approached; proportion considered potentially eligible.
SECONDARY OUTCOMES: fatigue, depression, baby-feeding, and hemoglobin at 1, 6 and 12 weeks; ferritin at 6 and 12 weeks. Surveys explored attitudes to trial participation.
RESULTS: Over 16 weeks and three sites, 26/34 (76%) women approached consented to trial participation, including eight (31%) Māori women. Of those potentially eligible, 26/167 (15.6%) consented to participate. Key participation enablers were altruism and study relevance. For clinicians and stakeholders the availability of research assistance was the key barrier/enabler. Between-group rates of fatigue and depression were similar. Although underpowered to address secondary outcomes, IV-iron and RBC-T compared with RBC-T were associated with higher hemoglobin concentrations at 6 (mean difference [MD] 11.7 g/L, 95% confidence interval [CI] 2.7-20.7) and 12 (MD 12.8 g/L, 95% CI 1.5-24.2) weeks, and higher ferritin concentrations at 6 weeks (MD 136.8 mcg/L, 95% CI 76.6-196.9).
DISCUSSION: Willingness to participate supports feasibility for a future trial assessing the effectiveness of IV-iron and RBC-T for postpartum anemia. Dedicated research assistance will be critical to the success of an appropriately powered trial including women-centered outcomes.
