Post-abortion contraception before hospital discharge after installation of a surveillance network in Brazil

To evaluate the use of contraception soon after abortion, ectopic, or molar pregnancy following the establishment of a surveillance network (MUSA).

A cross-sectional study of women admitted for abortion, or ectopic or molar pregnancy at UNICAMP Women's Hospital (part of the MUSA Network), Campinas, Brazil, between July 2017 and August 2019. Clinical and sociodemographic data were compared between women who initiated contraception before discharge and those who did not by using a Cochran-Armitage test and multiple logistic regression.

Overall, 382 women were enrolled (mean ± SD age, 29.6 ± 7.4 years). Most women (287, 75.2%) had abortions, and 146 (38.2%) initiated contraception before hospital discharge. The most common contraceptives were injectables (75, 51.4%) followed by pills (65, 44.5%). Use of contraception increased during the study period (Z=3.69, P<0.01), mostly due to injectables (Z=3.84, P<0.01). Factors independently associated with contraceptive initiation were admission in 2019 (odds ratio [OR], 2.65; 95% confidence interval [CI], 1.36-5.17) and not having an abortion for legal reasons (OR, 3.54; 95% CI, 1.30-9.62).

Implementation of a surveillance network optimized the health service and quality of care. There was an increase in contraception use and a vulnerable population was identified.
