- W2005559645 abstract "Objective: To evaluate cost-effectiveness of routine hemoglobin and hematocrit testing on admission to labor and delivery for expected vaginal delivery in an uncomplicated pregnancy. Methods: Postpartum charts were reviewed for 26–28-week hemoglobin or hematocrit values or both as well as for the term values. A sample of 101 patients was collected over a 6-week interval. Preterm pregnancies and pregnancies with multiple gestations, hypertension, and hemoglobinopathies were excluded. The primary outcomes were the frequency of term hemoglobin and hematocrit values below a critical threshold. The WHO definition was used for comparison across studies, and a more severe threshold was operationally defined by local providers because physicians may not change management for mild anemia. Two-tailed t tests were performed assuming unequal variances. Results: Mean hemoglobin and hematocrit values were 11.1g/dL and 31.5% at 26–28 weeks of gestation. At term, both values increased, to 11.6 g/dL and 34.3%. Eleven patients had term values less than values at 26–28 weeks of gestation. Only five patients had values less than 10 g/dL or 30% or both, and not one had values less than 8 g/dL or 25% (operationally defined). Conclusion: Statistically significant increases in hemoglobin and hematocrit values occurred at term compared with 26–28-week values. Although the term value was lower 11 times, only 5 were below the WHO threshold and not one was below our operationally defined values. Accordingly, term values are expected to be higher than 26–28-week values in uncomplicated pregnancies. By forgoing routine testing at term, significant cost savings can be recognized." @default.
