Within the framework of the 'Obstetric Peer Review' project (Verloskundige Onderlinge Kwaliteitsspiegeling, VOKS) statistical models have been developed to predict department specific intervention rates, based on the distribution of risk factors in each department. Subsequently the difference between the expected number of interventions (labour inductions, caesarean sections and vaginal operative deliveries) and the actual numbers were calculated for each year and subpopulation defined by the level of prematurity. Data used were available from the Perinatal Database of the Netherlands (Landelijke Verloskunde Registratie, LVR) concerning the years 1988-1992. Even after adjusting for many clinical risk factors the interdepartmental differences of intervention rates are both clinically relevant and statistically significant. It was also obvious, especially for the term population, that departments showed a consistent pattern with respect to the difference between their expected and observed intervention rates over these 5 years.
在“产科同行评审”项目（荷兰语：Verloskundige Onderlinge Kwaliteitsspiegeling，简称VOKS）的框架内，已开发出统计模型，用于根据各科室风险因素的分布预测科室特定的干预率。随后，计算了每年以及按早产程度定义的亚人群中预期干预次数（引产、剖宫产和阴道助产）与实际干预次数之间的差异。所使用的数据来自荷兰围产期数据库（荷兰语：Landelijke Verloskunde Registratie，简称LVR）中1988 - 1992年的数据。即使在对许多临床风险因素进行调整之后，各科室干预率的差异在临床方面仍具有相关性，在统计学上也具有显著性。同样明显的是，特别是对于足月儿人群，各科室在这5年期间预期干预率与观察到的干预率之间的差异呈现出一致的模式。
