Abstract
ObjectiveTo estimate the prevalence of obstructed labour, associated risk factors and outcomes across a network of referral hospitals in Nigeria.DesignRetrospective observational study.SettingA total of 54 referral-level hospitals across the six geopolitical regions of Nigeria.PopulationPregnant women who were diagnosed with obstructed labour during childbirth and subsequently underwent an emergency caesarean section between 1 September 2019 and 31 August 2020.MethodsSecondary analysis of routine maternity care data sets. Random-effects multivariable logistic regression was used to ascertain the factors associated with obstructed labour.Main outcome measuresRisk factors for obstructed labour and related postpartum complications, including intrapartum stillbirth, maternal death, uterine rupture, postpartum haemorrhage and sepsis.ResultsObstructed labour was diagnosed in 1186 (1.7%) women. Among these women, 31 (2.6%) cases resulted in maternal death and 199 (16.8%) cases resulted in postpartum complications. Women under 20 years of age (OR 2.03, 95% CI 1.50-2.75), who lacked formal education (OR 1.88, 95% CI 1.55-2.30), were unemployed (OR 1.94, 95% CI 1.57-2.41), were nulliparous (OR 2.11, 95% CI 1.83-2.43), did not receive antenatal care (OR 3.34, 95% CI 2.53-4.41) or received antenatal care in an informal healthcare setting (OR 8.18, 95% CI 4.41-15.14) were more likely to experience obstructed labour. Ineffective referral systems were identified as a major contributor to maternal death.ConclusionsModifiable factors contributing to the prevalence of obstructed labour and associated adverse outcomes in Nigeria can be addressed through targeted policies and clinical interventions.
