Management of Nonpregnant Women Presenting to the Emergency Department With Iron Deficiency Anemia Caused by Uterine Blood Loss: A Retrospective Cohort Study.

Abstract

BACKGROUND:

Women with abnormal uterine bleeding are commonly encountered in the emergency department (ED). Contemporary management of severe iron deficiency anemia (IDA) in this setting may be inadequate and expose patients to unnecessary blood transfusions.

OBJECTIVE:

We sought to describe the characteristics and management of women presenting to the ED with moderate to severe anemia caused by uterine bleeding. We hypothesized that blood transfusions were frequently administered to stable patients without severe symptoms or active bleeding.

METHODS:

This is a retrospective cohort study of women presenting to the ED from October 31, 2018 to March 31, 2019 with IDA from uterine bleeding. Eligible subjects were adult females with IDA caused by uterine blood loss, hemoglobin ≤10 g/dL, and who were discharged from the ED.

RESULTS:

One hundred twenty-seven encounters (117 unique patients, mean 40 years of age) met the eligibility criteria. No patients were hemodynamically unstable and clinically significant active bleeding was rare (6%). Blood transfusion was administered during 70 (55%) encounters, with ≥2 units given to more than half (53%) of those transfused. Subsequent ED visits (14%) and transfusions (16%) during the follow-up period were common.

CONCLUSION:

In this cohort of adult females with moderate to severe IDA caused by uterine bleeding, blood transfusion was often administered in the absence of hemodynamic instability or active hemorrhage, iron deficiency was inadequately treated, and a high rate of subsequent transfusions occurred. Future studies should investigate optimal indications for transfusion and emphasize adequate iron supplementation.
