Maternal and neonatal outcomes of Hepatitis C positive women attending a midwifery led drug and alcohol service: A West Australian perspective
MetadataShow full item record
Background: The Women and Newborn Drug and Alcohol Service (WANDAS) is a specialist, midwifery-led service providing pregnancy care to women dealing with alcohol and other drug (AOD) use, at the sole tertiary maternity hospital in Western Australia. Aim: To assess the antenatal, intrapartum and neonatal outcomes of women with Hepatitis C (HCV) who attended the WANDAS service between 2009 and 2012. Design: This retrospective cohort study used data obtained from computerised midwifery records. Univariate comparisons between those who were HCV positive and those who were not, were performed. Multivariable logistic regression was utilised to investigate the simultaneous factors associated with being HCV positive and an opiate user. Findings: The incidence of HCV in this cohort was 37% (213 of 570). Compared to those who were HCV negative those who were positive were more likely to: be older (P<0.001); use opioids in pregnancy (P<0.001); be an intravenous drug user (P<0.001); engage in polysubstance use (P<0.001); and receive an induction of labour (P=0.036). There were no intrapartum characteristics found to be significant at a multivariate level associated with being HCV positive and an opiate user, but there were a couple of neonatal complications. These were having a baby admitted to Special Care Nursery (OR 1.95, 95% CI 1.33–2.88, P<0.001) and a baby at increased risk of being diagnosed with neonatal abstinence syndrome (OR 3.40, 95% CI 2.24–5.15, P<0.001).Conclusion: Our findings highlight the complexity of caring for pregnant women who are HCV positive, they also highlight that all pregnant women who are AOD users are an at risk population. Implications for practice: These results improve our understanding of the obstetric and midwifery issues associated with caring for pregnant women who are HCV positive and the value of provision of specialist care from a multidisciplinary team, led by a consultant midwife.
