Frequency, timing, and diagnoses of antenatal hospitalizations in women with high-risk pregnancies

Abstract

Objective: To examine the frequency, time of gestation, and reasons for antenatal hospitalizations in women with medically high-risk pregnancies.

Study design: This secondary analysis reports all antenatal hospitalizations from a clinical trial testing transitional care to women with high-risk pregnancies. Data were collected from 1992 to 1996. Pregnant women with pregestational (n = 16) or gestational diabetes (n = 21), hypertension (n = 29), and diagnosed (n = 47) or at high risk for preterm labor (n = 37) were included. Diagnoses for each hospitalization and lengths of stay were collected from chart review and validated by attending physicians. Gestation was determined via ultrasonography. The sample (N = 150) consisted of predominantly African-American women, never married, between the ages of 15 and 40 with Medicaid insurance.

Results: Eighty-three percent (n = 125) of the women had one or more antenatal hospitalization with a mean length of stay of 123 hours. All women with diabetes were hospitalized at least once. Women with pregestational diabetes had the greatest number of hospitalizations whereas those with gestational diabetes had the least. Major reasons for hospitalizations were preterm labor, glucose control, premature cervical dilation, and preeclampsia.

Conclusion: Some hospitalizations could potentially be avoided or reduced through expanded patient education, improved screening, and more aggressive monitoring for early signs and symptoms of impending complications.
