Abstract

Objective: Determine if specific demographic and clinical variables are associated with intra-uterine contraception (IUC) placement by eight weeks postpartum.

Methods: This retrospective cohort study included all patients who delivered at Dartmouth-Hitchcock Medical Center (DHMC) (July-December 2008) who identified IUC as their preferred postpartum contraceptive method. Medical records of patients identified from the birth log were reviewed for preferred contraception, demographics, medical, obstetric, and social histories, as well as payer status. Chi-squared analysis was performed for categorical variables, and Mann-Whitney U test was used for continuous variables. Nonparametric continuous variables were categorized for regression modeling.

Results: 224 (34%) patients who delivered identified IUC as their preferred method of postpartum contraception. Of these, 94 (49.7%) women had an IUC placed by 8 weeks postpartum. In univariate analyses comparing those who received an IUC versus those patients who did not, only mean interdelivery interval in months (39.7 vs. 35.5, p=0.027) and mean gravidity (2.3 vs. 2.8, p=0.036) were statistically significant. In multivariate regression modeling, no variables were significantly associated with IUC placement.

Conclusions: While statically significant interdelivery interval and gravidity are not likely to be clinically significant. Multivariate modeling failed to identify a model associated with IUC placement suggesting that postpartum IUC placement is not well predicted by patient variables. Lack of identifying factors may support offering postplacental IUC placement to all patients who indicate IUC as their preferred contraceptive method.
