Antenatal care is evaluated based on observational trend studies, geographical comparisons, medical audits, and randomized trials. The last method is preferable and should be applied whenever feasible. Most components of antenatal care have not been properly evaluated. In order to evaluate an antenatal care program, a randomized study is suggested using geographical areas as units of randomization.
产前护理是根据观察性趋势研究、地域比较、医学审计和随机试验来评估的。最后一种方法更可取，只要可行就应采用。产前护理的大多数组成部分尚未得到适当评估。为了评估一个产前护理项目，建议采用以地理区域作为随机单位的随机研究。
