Comparison between public and private sectors of care and disparities in adverse neonatal outcomes following emergency intrapartum cesarean at term – A retrospective cohort study

BACKGROUND Perinatal outcomes may be influenced by a variety of factors including maternal demographics and medical condition as well as socio-economic status. The evidence for disparities in health outcomes stratified by type of care (public or private) is lacking. The aim of this study was to investigate short term neonatal outcomes following category 1 and 2 emergency cesareans at term between publicly and privately funded women at a single major tertiary centre in Australia. Category 1-immediate threat to life (maternal or fetal); Category 2-maternal or fetal compromise that is not immediately life-threatening. METHODS This was a retrospective, cross sectional study of 61355 term singleton babies born at the Mater Mother's Hospital in Brisbane, Australia in 2007-2014. We collected data from the hospital's maternity database and compared maternal demographics, indications for cesarean and neonatal outcomes for publicly and privately funded women. RESULTS Over the study period there were 32477 public and 28878 private, term singleton births. Compared to the publicly funded cohort, privately insured women were older, had lower BMI, were of Caucasian ethnicity, Australian born, nulliparous, had shorter labors and had lower rates of hypertensive disorders and diabetes. The most common indications for category 1 and category 2 cesareans in combination were non-reassuring fetal status followed by failure to progress in labor and malpresentation. For both category 1 and 2 cesareans, neonatal outcomes (Apgar score <7 at 5 minutes, abnormal cord gases, Neonatal Critical Care Unit admission rates, rates of severe respiratory distress and jaundice) were significantly worse in the publicly funded compared to the privately insured cohort Multivariate analyses controlling for maternal age, ethnicity, country of birth, parity, hypertension, diabetes mellitus, gestational age at birth and length of labour confirmed that private insurance status was highly protective for the perinatal outcomes of Apgar score <7 at 5 minutes (aOR 0.26, 95% CI 0.13-0.55), admission to NCCU (OR 0.51, 95% CI 0.30-0.92) and respiratory distress (aOR 0.60, 95% CI 0.41-0.86). CONCLUSION Birth in the private health sector was inversely associated with adverse neonatal outcomes following category 1 and 2 cesareans.
