This is a comparative study of the annual statistical returns to the Royal College of Obstetricians and Gynaecologists for 1993, 1994 and 1997/8. Over the study period there has been a decrease in normal vaginal deliveries of the order of 3% which is mirrored by a similar increase in caesarean section rates. Induction of labour rates have remained relatively constant 22.22%, 22.96% and 24.79% for 1993, 1994 and 1997/8, respectively. The overall instrumental delivery rate has changed little but there is an increasing preference for vacuum extraction over forceps. Analysis of the figures for each country (England, Scotland, Wales and Northern Ireland) show broadly similar trends.
这是一项对1993年、1994年以及1997/1998年向皇家妇产科学院提交的年度统计报告的比较研究。在研究期间，正常阴道分娩数量下降了约3%，剖宫产率则相应上升。引产率相对保持稳定，1993年、1994年和1997/1998年分别为22.22%、22.96%和24.79%。总体器械助产率变化不大，但相较于产钳，越来越多的人更倾向于使用真空吸引术。对每个国家（英格兰、苏格兰、威尔士和北爱尔兰）的数据进行分析后发现，趋势大致相似。
