RESUMEN
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, 13â¯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.

PURPOSE: Hypertension remains uncontrolled in the majority of affected patients despite treatment. Our goal was to identify specific action items in the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) guidelines that are not being translated into clinical practice. METHODS: We transformed the major JNC VI tables into a chart review instrument that was used to retrospectively analyze the medical records of 249 patients with newly diagnosed hypertension who had been followed for 18 months at one of six community-based primary care clinics. RESULTS: The practices of physicians deviated from the guidelines in several ways. Hypertension was staged initially on a single blood pressure recording in 85% (n = 212) of patients. No electrocardiogram was ordered for 89% (n = 221) of patients, while other mandatory laboratory tests were ordered for about 50%. After 18 months, 40% (72/179) of patients for whom prescription records were identified were still on monotherapy, and target blood pressure (<140/90 mm Hg) was achieved in only 33% (83/249) of patients. All of the 35 patients with diabetes received an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, but only 1.7 medications were prescribed per patient at study end. CONCLUSION: In this clinic system, staging of blood pressure with multiple measurements, thorough assessment of global cardiovascular risk, and titration of multiple antihypertensive medications to achieve blood pressure goal are components of the JNC VI guidelines that are not well translated into clinical practice. Overcoming these practice defects will require innovative multilevel interventions.
