Analyses of the published results of national surveys and specific studies, as well as of the official stillbirth statistics, consistently point to the conclusion that perinatal mortality is significantly higher in consultant obstetric hospitals than in general practitioner maternity units or at home, even after allowance has been made for the greater proportion of births in hospital at high pre-delivery risk. Unpubliched results of the British births 1970 survey, which have now become available, make possible a direct and authoritative analysis of data on the safest place of birth. Not only does this make the earlier conclusion more certain, but it confounds the doctrine that obstetric intranatal care is particularly beneficial for high pre-delivery risk births. There is no evidence from recent years that the findings of 1970 are not equally valid in the 1980s.
对全国性调查和特定研究的已发表结果，以及官方死产统计数据的分析一致表明，即使在考虑到高危分娩在医院出生的比例较高之后，产科顾问医院的围产期死亡率仍显著高于全科医生产科病房或家中。现已获得的1970年英国出生情况调查的未发表结果，使得对最安全分娩地点的数据进行直接且权威的分析成为可能。这不仅使早期结论更加确定，而且还推翻了产科产时护理对高危分娩特别有益的学说。近年来没有证据表明1970年的研究结果在20世纪80年代不具有同等效力。
