The influence of prior obstetrical history on current 17-hydroxyprogesterone caproate use.

To determine if gestational age of prior preterm delivery influences a woman's receipt of 17-hydroxyprogesterone caproate (17-ohp-c). retrospective cohort of women eligible for 17-ohp-c at duke obstetrics clinic were identified by medical record review. sociodemographic and clinical characteristics were abstracted. results. of 104 eligible subjects,82 (78.8%) were offered 17-ohp-c. of these,thirty-four (41.5%) declined. the median gestational age of the most recent preterm delivery was significantly lower among subjects who accepted 17-ohp-c as compared to those who declined (28.7 vs. 34.0 weeks,p = .02) and in subjects offered 17-ohp-c compared to those not offered 17-ohp-c (30.2 vs. 36.0 weeks,p = .03). subjects not offered 17-ohp-c were more likely to have had an interval term delivery (31.8% vs. 9.7%,p = .009) women with earlier preterm deliveries were more likely to be offered and accept 17-ohp-c. prior obstetric history may influence both providers' and patients' willingness to discuss and/or accept 17-ohp-c.
