Adequacy of prenatal care among women with psychiatric diagnoses giving birth in California in 1994 and 1995

Abstract

Objective: Although poor prenatal care is detrimental to maternal and infant health, few studies have assessed the adequacy of prenatal care among women with psychiatric diagnoses. This investigation examined the association between chart-recorded psychiatric and substance use diagnoses at the time of delivery and adequacy of prenatal care among all women delivering babies in California hospitals during 1994 and 1995.

Methods: The authors undertook an archival analysis of data from the California Health Information for Policy Project (CHIPP), which consists of linked hospital discharge and birth certificate data for 1,094,178 deliveries in 1994 and 1995. The associations between International Classification of Diseases, 9th Revision, Clinical Modification psychiatric and substance abuse diagnoses and level of prenatal care were examined. Logistic regression analyses were conducted to assess the association between maternal diagnostic category and inadequate prenatal care while controlling for payment source, age, education, race, marital status, and parity (previous births).

Results: Women who received psychiatric and substance use diagnoses demonstrated significantly increased risk of inadequate prenatal care compared with women without those diagnoses.

Conclusions: Psychiatric diagnoses were associated with an increased risk of inadequate prenatal care; the association between psychiatric and substance use diagnoses and poor prenatal care persisted even after the analysis controlled for known risk factors. Future investigations will need to elucidate the processes of prenatal care for women with psychiatric disorders so that preventive interventions can be developed.
