Purpose: To explore whether epidemiological shifts regarding reproduction and pregnancy have influenced the spectrum of indications for late termination of singleton pregnancies (TOP) above 17 weeks of gestation and to evaluate temporal changes in maternal demographics and fetal indications over the last 16 years.
Methods: Retrospective single-center cohort study involving all late TOPs preceded by feticide between 1 January 2004 and 31 December 2019 at a tertiary referral hospital in Austria. Outcome variables were retrieved and a time trend assessed between two 8-year intervals (2004-2011 versus 2012-2019).
Results: Between January 2004 and December 2019, a total of 209 singleton pregnancies (50.7% male; 46.9% female fetuses, 2.4% no disclosed sex) were terminated medically at a median gestational age of 25+1 (17+3-37+1) weeks at our institution. Predominant conditions legally justifying the late medical abortion were abnormaltities of the brain/central nervous system (n = 83; 39.7%), chromosomal aberrations (n = 33; 15.8%), complex malformations (n = 31; 4.8%) and abnormaltities of the musculosceletal system including diaphragmatic hernias (n = 18; 8.6%), as reflected by the ICD-10-categories “Congenital malformation of the central nervous system”, “Other congenital malformations” and “Chromosomal abnormalities”. No changes were observed with regards to maternal age (30.1 ± 5.9 vs. 31.0 ± 6.0 years; p = 0.315) nor frequency of assisted reproductive technologies (7.0% vs. 8.5%; p = 0.550). Despite a 2.5-fold increase in incidence of late TOPs, no epidemiological changes in maternal or fetal characteristics were observed over the last 16 years.
Conclusion: Population profile and indications for late TOPs followed by feticide remain unchanged over time.
