Abstract

INTRODUCTION: The aim of this study was to determine the prognostic value of the first urinary albumin/creatinine ratio (ACR) for adverse maternal and neonatal outcomes and how it relates to other prognostic factors. MATERIAL AND METHODS: We performed a retrospective cohort study from December 2009 to February 2012 with analysis of demographic, clinical and biochemical data from two obstetric day assessment units in hospitals in Southeast Scotland. We included 717 pregnant women, with singleton pregnancies after 20 weeks gestation, referred for evaluation of suspected pre-eclampsia and having their first ACR performed. The ability of ACR to predict future outcomes was assessed in both univariable and multivariable logistic regression models. The latter assessed its prognostic value independent to (adjusting for) existing prognostic factors. Primary outcome measures were maternal and neonatal composite adverse outcomes, and a secondary outcome was gestation at delivery. RESULTS: 204 women (28.5%) experienced a composite adverse maternal outcome. 146 women (20.4%) experienced a composite adverse neonatal outcome. Multivariate analysis of log-transformed ACR, demonstrated that a 1-unit increase in log ACR is associated with an increased odds of adverse maternal (Odds Ratio 1.60, 95% CI 1.45-1.80) and adverse neonatal (Odds Ratio 1.15, 95% CI 1.02-1.29) composite outcomes, and with reduced gestational age at delivery (coefficient: -0.46, 95% CI -0.54 to -0.38). CONCLUSIONS: ACR is an independent prognostic factor for maternal and neonatal adverse outcomes in suspected pre-eclampsia. ACR may be useful to inform risk predictions within a prognostic model.
