Hospitalization due to abortion in Brazil, 2008-2018: an ecological time-series study

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Objective:

To analyze the temporal trend of hospitalizations caused by abortion in Brazil between 2008-2018, according to region and federal units (FU).

Methods:

Ecological study concerning hospitalizations due to abortion of women of childbearing age, from Hospital Information System data. The rates were calculated according the characteristics of women. The trend was assessed by Prais-Winsten generalized linear regression.

Results:

The 2,258,104 hospitalizations due to abortion represent 5% of all hospitalizations in women of childbearing age. Hospitalizations for abortions in Brazil reduced 0.76 in the period; this trend occurred in 19 Brazilian FUs and all regions, except the South (stable). There was a significant reduction (p<0.001) in hospitalizations for spontaneous abortion and in admissions for abortion in women aged 20 to 39 years.

Conclusion:

A temporal trend of reduction in the hospitalizations due to abortion in Brazil was found, variating according to characteristics of the woman, FU and region of residence.
