Retrospective analysis of stillbirth and induced termination of pregnancies: Factors affecting determination

Abstract

Objective: The aim of this study was to identify the factors and frequencies of induced termination of pregnancies.

Materials and methods: This is a retrospective study of 488 terminations of pregnancies (TOPs) between January 2011 and December 2021 to demonstrate the factors affecting the decision to terminate the pregnancy. All cases had been hospitalized to manage the induction of labor. Methods included serial multiple laminaria dilation of the cervix and administration of a cervical misoprostol suppository. After induction of labor, the subject may experience amniotomy, instrumental evacuation of the uterus, and even hysterotomy. Pre-procedure counseling included an agreement to share medical records (paper-based and electronic). We verified the indications for all patients seeking TOPs. All cases were performed according to known diagnostic classifications and divided into seven groups for analysis.

Results: The patient ages ranged from 12 to 46 years. The median maternal age was 34 years [interquartile range (IQR) 30, 37]; 52.2% had at least one prior delivery. The pre-procedure diagnosis was divided into seven groups including the following: chromosomal and genetic abnormalities (146/488, 29.9%), no intrauterine heartbeats (126/488, 25.8%), structural anomalies (84/488, 17.2%), elective termination (56/488, 11.5%), preterm premature rupture of membranes (PPROM) (42/488, 8.6%), cervical incompetence (32/488, 6.6%), and other conditions (2/488, 0.4%). After excluding elective terminations, the eleven-year rate of fetal death and stillbirth to births did not show significant changes from 2011 to 2021.

Conclusions: Knowing the factors underlying the decision to induce intrauterine fetal death (IUFD) including reasons for objecting to pregnancy are important for obstetricians-they can offer better planning and medical counseling. It is important to educate all women about family planning to prevent large numbers of unwanted and unsafe pregnancy terminations.
