The special prenatal clinic: one approach to women and substance abuse

Compliance with prenatal care visits in substance abusers

OBJECTIVE

We sought to determine whether pregnant, inner-city substance abusers, cared for in a multidisciplinary setting, had comparable numbers of missed appointments and similar outcomes in comparison with a low-risk patient population.

METHODS

A retrospective review was conducted on a sample of 97 patients with uncomplicated prenatal care over a 7-year period (1994-2001). They were compared to a sample of 88 substance abusers cared for and delivered at Bellevue Hospital over the same period. Demographic information was recorded, as well as frequency of prenatal visits, number of missed appointments, birth weight, and gestational age at delivery.

RESULTS

In our population, substance abusers were found to be significantly older (28.9 vs. 25.6 years, p < 0.0001), had had more pregnancies (4.3 vs. 2.4, p < 0.0001) and had had more children (2.0 vs. 0.7, p < 0.0001) than controls. Both substance abusers and control patients had a similar number of scheduled appointments (11.4 in each group, p = 0.99), but substance abusers missed more appointments (1.6 vs. 0.7, p < 0.0005).

CONCLUSIONS

When cared for in a multidisciplinary setting, substance abusers will attend an adequate number of prenatal visits. However, they are still more likely than non-substance abusers to miss visits, although the difference may not be clinically significant.
