All data were obtained from the disease surveillance points system, and two proportions for assigning chronic pulmonary heart disease （PHD） as GC to IHD were from GBD2010 and GBD2013,展开更多

Data Sources: The CDC Wonder system for the years 2000-2015 using the following definitions of maternal mortality and associated ICD-CM-10 codes: 1) Maternal deaths up to 42 days after delivery (A34, O00-O99, except O96-O97);2) Maternal deaths within one year after delivery (A34, O00-O99, except O97);3) All maternal deaths (A34, O00-O99). Study Design: For each year between 2000-2015, we provided maternal deaths, live births, and calculated maternal mortality ratios (MDR). For deaths within 42 days, we also calculated adjusted mortality ratios (ADR). Principal Findings: Maternal mortality comparisons which utilize inconsistent definitions and apply non-validated statistical adjustments produce specious results. Conclusions: Variation and inconsistency in definitions, coding, and other reporting anomalies render the current aggregated vital statistics on maternal mortality inadequate for accurate trending and service impact studies. The definition of maternal mortality must be expanded to all outcomes of pregnancy: births, induced abortions, and natural fetal losses.展开更多
