    Journal: JAMA Netw Open; 2023 Sep 05; 6(9):e2332100. PubMed ID: 37656455.
    Abstract:
    IMPORTANCE: Postpartum transfusion is the most common indicator of severe maternal morbidity in the US. Higher rates of anemia are associated with a higher blood transfusion rate. OBJECTIVE: To determine if providing, rather than recommending, supplements with iron at prenatal visits in a medically underserved community is associated with improved hematologic indices and reduced blood transfusion. DESIGN, SETTING, AND PARTICIPANTS: In this quality improvement study, patients who delivered between May 13 and December 13, 2020, and thus were provided a prenatal supplement with iron throughout pregnancy were compared with those who delivered between January 1 and August 1, 2019, before supplements were dispensed. The study was conducted at Parkland Health, a safety net hospital in Dallas, Texas, with a 95% Medicaid-funded or self-pay population and included all patients who delivered at our institution during the study period with available hematologic data. EXPOSURES: In the earlier cohort, all patients were recommended to obtain and take iron supplements. In the later cohort, prenatal supplements with iron were dispensed via clinic pharmacy to all patients during prenatal visits. MAIN OUTCOMES AND MEASURES: Maternal hematocrit levels (28-32 weeks, delivery admission, and discharge), rates of anemia (hematocrit <30%), and postpartum transfusion for acute blood loss anemia were compared using χ2 and analysis of variance methods with P < .05 considered significant. The analysis took place in July of 2022. RESULTS: Overall, 13 910 patients (98%) met inclusion criteria (mean age [SD], 27.9 [6.5] and 27.6 [6.5] years, mean [SD] body mass index at first visit, 29.2 [6.6] and 29.3 [6.6]). Mosty of the patients in both cohorts were of Hispanic ethnicity (76%). Providing iron-containing prenatal supplements was associated with higher average hematocrit levels at all time points including a mean difference of 1.27% (95% CI, 1.13%-1.42%) on admission for delivery, when compared with those who were not directly dispensed iron. Among patients prior to providing supplements, 18% had anemia on admission compared with 11% with iron-containing supplements dispensed (risk ratio [RR], 0.61; 95% CI, 0.56-0.66). Postpartum transfusion for acute blood loss anemia was reduced by one-third in patients after program implementation from 10 per 1000 to 6.6 per 1000 (RR, 0.62; 95% CI, 0.43-0.91). CONCLUSIONS AND RELEVANCE: In this quality improvement study, providing supplements with iron to patients at prenatal visits was associated with improved hematocrit levels, rates of anemia, and reduced transfusions unrelated to obstetric catastrophes among a predominantly Medicaid population.
