title: Lack of prenatal care increases the rate of recurrent preterm delivery and health care costs when compared to university hospital-based prenatal care.
abstract: Objective: To compare perinatal outcomes and total health care costs for patients with a previous history of preterm delivery (PTD) cared for in an inner-city university hospital house staff (HS) clinic vs pregnant patients who have not received any prenatal care (NPC).Study Design: We conducted a retrospective review of pregnant women with a history of PTD delivered at our institution between January 1994 and December 1996. Inclusion criteria were a history of at least one previous PTD. Prenatal care was given in a comprehensive setting in a teaching hospital. Exclusion criteria were infants with major malformations and multiple gestations. Data were obtained on maternal demographics and history of prenatal visits.Results: The study groups consisted of 96 HS and 53 NPC patients. There were no differences in maternal demographics, however, the number of prior preterm births was greater in the NPC group (1.59 vs 1.23, P =.003). The incidence of recurrent PTD (<34 weeks) was greater in the NPC group (49% vs 13%, P = <.001). The mean gestational age at time of delivery was decreased in the NPC group (33 weeks vs 37.2 weeks, P = <.001). The length of NICU stay was greater in the NPC group (15.6 vs 3.1 days, P =.001). The mean birth weight was less in the NPC group (2172 g vs 2786 g, P = <.001). The mean total mother-infant costs were significantly less in the HS group ($7,127 vs $18,047, P =.003). Even HS patients with only one prenatal visit had a significantly lower incidence of PTD (16% vs 75%, P =.04).Conclusions: Inner-city patients with a history of PTD who received even minimal prenatal care in a university HS clinic had a significantly lower incidence of recurrent PTD than those who had no prenatal care. Prenatal care also lowers total health care costs in women with a history of PTD. The coordinated multidisciplinary aspect of care provided at academic centers may have a positive impact on the problem of PTD.
