Predictors of stillbirth at Tema General Hospital: a registry–based retrospective study

Abstract

Background In 2015, the global incidence of stillbirths reached 2.6 million, equating to more than 7,178 deaths daily. The stillbirth rate in Ghana during this period was recorded at 22.7 per 1,000 births. While extensive research has been undertaken in high-income countries to document stillbirth rates and elucidate the associated risk factors, there is a notable paucity of similar studies in Ghana. This study therefore determined the predictors of stillbirth in a Ghana ian referral hospital. Methods We conducted a facility-based 1:1 unmatched case–control study comparing data of women who had stillbirths to those who had live births at the Tema General Hospital in 2019. Data were obtained from the hospital records using a data extraction form that was specifcally designed for this purpose. We extracted and entered data into Microsoft Excel 2013, cleaned, and analyzed using STATA 15. Frequency and percentage distributions were used to describe the characteristics of respondents. Bivariate and logistic regression analyses were carried out to examine predictors of stillbirth. Results Of 552 mothers included in the study, the mean age of mothers with and without stillbirths was 31.4 (SD±6.1) years, and 28.8 (SD±6.0) years respectively. We identifed Mothers aged 40 years and older [aOR=5.5; (95% CI 1.1–26.9)], Maternal employment [aOR=2.5; (95% CI=1.2—5.3)], Caesarean section [aOR=1.9; (95% CI=1.2—2.9)], Infants with low birth weight [aOR=8.7; (95% CI=5.2- 14.7)], Hypertensive mothers [aOR=1.9; (95% CI=1.2—2.8)] to signifcantly increased likelihood of stillbirth. Primary education [aOR=0.4; (95% CI=0.2–0.8)], Tertiary education [aOR=0.2; (95% CI=0.1–0.5)], Mothers who attended four or more antenatal care (ANC) [aOR=0.6; (95% CI=0.3—0.9)] signifcantly lower odds of experiencing stillbirth. Conclusion A combination of socio-demographic, maternal, and foetal variables predicted stillbirth at Tema General Hospital in 2019. Recommendations for improving birth outcomes at the hospital entail persistent community aware ness initiatives targeting the impact of pivotal risk factors, timely stratifcation of pregnancies based on risk assess ment, and the establishment of specialized Antenatal Care (ANC) services tailored for high-risk cohorts.
