Near miss audit in obstetrics

Purpose of review Over the past decade, there has been increasing interest internationally in studying maternal near misses, or severe morbidity, to complement traditional audit of maternal mortality. This review summarizes studies in this field published during 2005-2006. Recent findings There is wide variation among published studies in terms of definitions of near miss, sources of data, and assessment of quality of care. Some investigators focus on single categories of near miss (e.g. postpartum haemorrhage, obstetric hysterectomy, intensive care unit admission), whereas others include multiple categories (ranging from two to 14). Some groups identify cases from routinely collected administrative data; whereas others search hospital registers and individual case records. Many investigators make no attempt to assess quality of care or preventability, but restrict their studies to the reporting of rates of severe morbidity. Others assess care by means of interviews with survivors or case note review, but study only a sample of cases and cannot report incidence rates. A minority of investigators both report incidence rates and assess quality of care. Summary Near miss audit is increasingly used to complement maternal mortality review. Standardization of inclusion criteria and of methods for case assessment would facilitate comparisons over time and among countries.
