Objectives: To explore how specific measures of antenatal care utilization are associated with outcomes in pregnancies complicated by preeclampsia and eclampsia in Ghana.
Study design: Participants were adult pregnant women with preeclampsia or eclampsia at a tertiary hospital in Ghana. Antenatal care utilization measures included timing of first visit, total visits, facility and provider type, and referral status. Antenatal visits were characterized by former and current World Health Organization recommendations, and by gestational age-based adequacy.
Main outcome measures: Composites of maternal complications and poor neonatal outcomes. Multivariate logistic regressions identified associations with antenatal care factors.
Results: Among 1176 participants, median number of antenatal visits was 5.0 (IQR 3.0-7.0), with 72.9% attending ≥4 visits, 19.4% attending ≥8 visits, and 54.9% attending adequate visits adjusted for gestational age. Care was most frequently provided in a government polyclinic (n = 522, 47.2%) and by a midwife (n = 704, 65.1%). Odds of the composite maternal complications were lower in women receiving antenatal care at a tertiary hospital (aOR 0.47, p = 0.01). Odds of poor neonatal outcomes were lower in women receiving antenatal care at a tertiary hospital (aOR 0.56, p < 0.001), by a specialist Obstetrician/Gynecologist (aOR 0.58, p < 0.001), and who attended ≥8 visits (aOR 0.67, p = 0.04). Referred women had twice the odds of a maternal complication (aOR 2.12, p = 0.007) and poor neonatal outcome (aOR 1.68, p = 0.002).
Conclusions: Fewer complications are seen after receiving antenatal care at tertiary facilities. Attending ≥8 visits reduced poor neonatal outcomes, but didn't impact maternal complications. Quality, not just quantity, of antenatal care is essential.
