Neonatal mortality rates vary widely among countries. According to data from the World Health Organization, neonatal mortality in low- and low-middle-income countries is ∼30 per 1000 babies. In upper middle-income countries, that number was just 10 per 1000. In the highest-income countries, it was <5 per 1000. These data may not be accurate. Many countries do not report the tiniest babies as live births. Thus, their reported infant mortality rates are much lower than their actual infant mortality rates. Another big difference between countries is in the rate at which congenital anomalies are diagnosed prenatally and the rate at which pregnancies are terminated by induced abortion. International comparisons therefore reflect differences in the way countries define live birth, the comprehensiveness of the reporting of live births even by their own definitions, differences in the prevalence of congenital anomalies, the rate at which those congenital anomalies are diagnosed prenatally, and the percentage of pregnancies with congenital anomalies that end in abortion. This article reviews these differences and discusses the implications for the ways in which we think about international differences in decisions about life-sustaining treatment.
各国的新生儿死亡率差异很大。根据世界卫生组织的数据,低收入和中低收入国家的新生儿死亡率约为每1000名婴儿中有30例。在中高收入国家,这一数字仅为每1000名中有10例。在高收入国家,该数字低于每1000名中有5例。这些数据可能并不准确。许多国家并不将最小的婴儿登记为活产。因此,它们报告的婴儿死亡率远低于实际婴儿死亡率。各国之间的另一个重大差异在于产前诊断先天性异常的比率以及人工流产终止妊娠的比率。因此,国际比较反映出各国在活产定义方式上的差异、即使按照本国定义活产报告的全面性、先天性异常患病率的差异、产前诊断这些先天性异常的比率,以及因先天性异常而终止妊娠的怀孕比例。本文回顾了这些差异,并讨论了其对我们思考维持生命治疗决策中的国际差异方式的影响。
