目的：我们的目的是更新全国对严重妊娠并发症的估计，并描述妊娠期间住院的相关孕产妇特征，应用扩展的孕产妇发病率定义。研究设计：从1991年和1992年全国医院出院调查数据中，我们估计了每100次分娩的住院率，并比较了产妇特征的相对比率。我们用SUDAAN程序计算了标准误差，并估计了相对比率的95%置信区间。结果：1986年至1987年和1991年至1992年期间，因妊娠并发症住院的可能性出现下降，尽管主要是因流产住院。1991年和1992年，与怀孕有关的住院人数为18.0 /100（白人17.2 /100，黑人28.1 /100）。产科住院的构成比为12.3，妊娠损失住院的构成比为4.4，非产科住院的构成比为1.4；黑人的所有比率都高于白人。结论：产妇住院仍然是产前护理的重要组成部分。由于少报和医疗实践的变化，最近产妇住院率的下降可能并不代表产妇发病率的真正下降。
OBJECTIVE: Our purpose was to update the national estimate of severe pregnancy complications and describe associated maternal characteristics of hospitalizations during pregnancy, applying an expanded definition of maternal morbidity.STUDY DESIGN: From 1991 and 1992 National Hospital Discharge Survey data, we estimated ratios of hospitalizations per 100 deliveries and compared relative ratios by maternal characteristics. We computed standard errors with the SUDAAN program and estimated 95% confidence intervals for relative ratios.RESULTS: The likelihood of hospitalization for pregnancy complications appeared to decline between the period 1986 and 1987 and the period 1991 and 1992, although primarily for pregnancy loss hospitalizations. In 1991 and 1992 there were 18.0 total pregnancy-associated hospitalizations/100 births (17.2 for whites, 28.1 for blacks). Component ratios were 12.3 for obstetric hospitalizations, 4.4 for pregnancy loss hospitalizations, and 1.4 for nonobstetric hospitalizations; all ratios were higher for blacks than for whites.CONCLUSIONS: Maternal hospitalization remains a substantial component of prenatal care. Because of underreporting and changes in medical practice, recent declines in maternal hospitalization may not represent true reductions in maternal morbidity.
