Provision of Long-acting Reversible Contraception at Surgical Abortion-A Cross-sectional Nationwide Register Study

Introduction: Provision of long-acting reversible contraception (LARC) at surgical abortion is safe, practical, and leads to higher user rates than does delayed provision. The aim of this study was to explore whether provision of LARC at surgical abortion is associated with known risk factors for subsequent abortions and inconsistent use of contraception, including sociodemographic factors and psychiatric disorders.

Material And Methods: This was a register-based cross-sectional study of 6251 women having a surgical abortion in Sweden. Data were collected from National health and population registers. Women with procedure codes for surgical abortion were identified in the National Patient Register from October 2016 to December 2018. Information from Statistics Sweden, the National Patient Register, and the Swedish prescribed drug register on sociodemographic factors, psychiatric disorders, and dispensed LARC was added and linked on an individual level. Associations of sociodemographic factors and psychiatric disorders with LARC provision were explored with generalized logit mixed models and presented as crude and adjusted odds ratios with 95% confidence intervals (CIs).

Results: The overall rate of LARC provision at the time of the abortion was 2515/6251 (40.2%). Younger age and lower level of education were associated with an increased likelihood of LARC provision. In the study population, 2624/6251 (42.0%) patients had a pre- or post-abortion psychiatric disorder, a factor associated with an increased likelihood of LARC provision compared with women with no such disorders (adjusted odds ratio 1.21; 95% CI 1.08-1.34). The highest rates and odds were seen among women with personality, substance use, and/or neurodevelopmental disorders and among women with multiple psychiatric disorders.

Conclusions: Sociodemographic risk factors and psychiatric disorders were associated with increased LARC provision at surgical abortion, indicating that women at high risk of unwanted pregnancies are provided with effective contraception. Still, less than half of all women undergoing surgical abortion were provided with LARC, suggesting that contraceptive access and counseling prior to a surgical abortion can be improved.
