The predictive value of signs and symptoms in predicting adverse maternal and perinatal outcomes in severe preeclampsia in a low-resource setting, findings from a cross-sectional study at Mpilo Central Hospital, Bulawayo, Zimbabwe.

Abstract Objectives In low resource settings symptoms and signs may be used to identify which women require intervention to mitigate the risks of severe preeclampsia. This study aimed to report the frequency of signs and symptoms in women with severe preeclampsia and to determine their predictive value for adverse maternal and perinatal outcomes. Study design A retrospective cross-sectional study of women with severe preeclampsia from 01/01/2016 to 31/12/2018 at Mpilo Central Hospital, Bulawayo, Zimbabwe. Multivariate logistic regression was used to determine whether symptoms and signs were independently associated with the co-primary outcomes. Main outcome measures The co-primary outcome measures were a composite of maternal complications including major organ dysfunction or mortality and a composite measure of severe perinatal morbidity or mortality. Results Symptoms were present in 58.8% of women with severe preeclampsia; headache and epigastric pain were most commonly reported (47.9% and 22.4% of women respectively). Most symptoms and signs were not independently predictive of adverse maternal or perinatal outcomes. Vaginal bleeding with abdominal pain reduced odds of adverse maternal outcome (Adjusted Odds Ratio (AOR) 0.16, 95% Confidence Interval (CI) 0.03–0.84; p = 0.03), systolic blood pressure of 161–180 mmHg increased odds of adverse maternal outcome (AOR 2.71, 95% CI 1.14–6.41, p = 0.03) and birthweight ≤ 1500 g increased odds of adverse perinatal outcome (AOR 23.21, 95% CI 7.70–69.92, p  Conclusions Maternal signs and symptoms are ineffective predictors of maternal or perinatal morbidity and mortality; as such they cannot be used alone to predict which women would benefit from intervention in severe preeclampsia.
