Patient Preferences for Immediate Compared With Delayed Postpartum Intrauterine Device Placement

Abstract

OBJECTIVE: To use choice-based conjoint survey methodology to evaluate patient values and decision making regarding immediate compared with delayed placement of postpartum intrauterine devices (IUDs). METHODS: We conducted a cross-sectional study in which we surveyed 200 nonpregnant, parous patients. Participants chose between hypothetical postpartum IUDs varying in multiple attributes (hormonal or nonhormonal IUD type, placement timing, 1-year efficacy, expulsion risk, risk of lost strings, and malposition risk). The primary outcome was preference for immediate compared with delayed postpartum IUD placement and importance of placement timing relative to other attributes. Secondarily, we evaluated whether demographic and neighborhood characteristics were associated with timing preference and attribute importance. RESULTS: We included 190 participants for analysis. Most participants (62.6%) preferred delayed placement. There was no significant difference in timing preference by race (P=.28) or block-level Area Deprivation Index score (P=.27). Patients who preferred immediate placement were more likely to have public insurance than private insurance (70.4% vs 29.6%, P=.04); however, the majority of patients (55.1%) with public insurance still preferred delayed placement. Attributes of IUD type, malposition risk, 1-year efficacy, and expulsion risk all had greater effects on patient decision making than placement timing. There was no difference in attribute importance by race (P=.30), Area Deprivation Index score (P=.88), or insurance type (P=.22). CONCLUSION: Patients preferred the higher efficacy and lower complication rates of delayed postpartum IUD placement over the convenience of immediate placement. Insurance considerations may affect these timing preferences. There was no difference in attribute importance between demographic groups or based on neighborhood-level factors, indicating that, although both immediate and delayed postpartum IUD placement should be offered, counseling should not vary according to individual demographic characteristics.
