Abstract

Objective To evaluate the factors associated with abortion complications following the implementation of the good-practice surveillance network Mujeres en Situación de Aborto (Women Undergoing Abortion, MUSA, in Spanish).

Methods A cross-sectional study with women who underwent abortion due to any cause and in any age group at UNICAMP Women's Hospital (part of MUSA network), Campinas, Brazil, between July 2017 and Agust 2019. The dependent variable was the presence of any abortion-related complications during hospitalization. The independent variables were clinical and sociodemographic data. The Chi-square test, the Mann–Whitney test, and multiple logistic regression were used for the statistical analysis.

Results Overall, 305 women were enrolled (mean ± standard deviation [SD] for age: 29.79 ± 7.54 years). The mean gestational age was 11.17 (±3.63) weeks. Accidental pregnancy occurred in 196 (64.5%) cases, 91 (29.8%) due to contraception failure. At least 1 complication was observed in 23 (7.54%) women, and 8 (34.8%) of them had more than 1. The most frequent complications were excessive bleeding and infection. The factors independently associated with a higher prevalence of complications were higher gestational ages (odds ratio [OR]: 1.22; 95% confidence interval [95%CI]: 1.09 to 1.37) and contraceptive failure (OR: 3.4; 95%CI: 1.32 to 8.71).

Conclusion Higher gestational age and contraceptive failure were associated with a higher prevalence of complications. This information obtained through the surveillance network can be used to improve care, particularly in women more susceptible to unfavorable outcomes.

Resumo

Objetivo Avaliar os fatores associados às complicações em casos de aborto após a implementação da rede de vigilância de boas práticas Mujeres en Situación de Aborto (Mulheres em Situação de Aborto, MUSA, em espanhol).

Métodos Um estudo transversal, com mulheres admitidas por aborto de qualquer causa e em qualquer faixa etária, no Hospital da Mulher da UNICAMP (parte da rede MUSA), Campinas, Brasil, entre julho de 2017 e agosto de 2019. A variável dependente foi a presença de qualquer complicação relacionada ao quadro de aborto durante a hospitalização. As variáveis independentes foram dados clínicos e sociodemográficos. O teste de qui-quadrado, o teste de Mann-Whitney, e a regressão logística múltipla foram usados na análise estatística.

Resultados Foram incluídas 305 mulheres (média ± desvio padrão [DP] da idade: 29,79 ± 7,54 anos). A idade gestacional média foi de 11,17 (±3,63) semanas. A gravidez não foi planejada em 196 (64,5%) casos, 91 (29,8%) devido a falha de contraceptivo. Pelo menos 1 complicação foi observada em 23 (7,64%) mulheres, 8 (34,8%) das quais apresentaram mais de uma complicação. As complicações mais frequentes foram sangramento excessivo e infecção. Os fatores independentemente associados à maior prevalência de complicações foram idades gestacionais maiores (razão de chances [OR]: 1.22; intervalo de confiança de 95% [IC95%]: 1.09 a 1.37) e falha de contraceptivo (OR: 3.4; IC95%: 1.32 a 8.71).

Conclusão Maior idade gestacional e falha de contraceptivo estiveram associados à maior prevalência de complicações. As informações obtidas pela rede de vigilância podem ser usadas para melhorar o cuidado, particularmente nas mulheres mais suscetíveis a desfechos desfavoráveis.
