Between 1955 and 1962, 145 maternal deaths were reported in the Province of British Columbia. One hundred of them were due to obstetrical causes. Of these deaths, hemorrhage was by far the commonest cause (40 cases), followed in frequency by vascular accidents (23 cases), infections (17 cases), toxemia (10 cases), anesthetic deaths (five cases), and other causes (five cases). Significant avoidable factors were noted in 80%. Indirect obstetrical deaths accounted for 29 cases, or 20% of all maternal mortalities. The most frequently encountered causes of indirect obstetrical deaths were cardiac (nine cases) and vascular accidents (six cases). Avoidable factors were considered to be present in 19 of the 29, an incidence of 65%.When all deaths were considered together, 72% were felt to have significant avoidable factors when judged against an academic standard. It was also apparent that some 40% to 50% of deaths were intimately involved with social factors.
1955年至1962年间，不列颠哥伦比亚省报告了145例孕产妇死亡病例。其中100例死于产科原因。在这些死亡病例中，出血是最常见的原因（40例），其次是血管意外（23例）、感染（17例）、毒血症（10例）、麻醉死亡（5例）以及其他原因（5例）。80%的病例存在显著的可避免因素。间接产科死亡病例有29例，占孕产妇死亡总数的20%。间接产科死亡最常见的原因是心脏疾病（9例）和血管意外（6例）。29例中有19例被认为存在可避免因素，发生率为65%。当综合考虑所有死亡病例时，按照学术标准判断，72%的死亡病例被认为存在显著的可避免因素。同样明显的是，约40%至50%的死亡病例与社会因素密切相关。
