One important premise for estimation of the development of the results of defined care systems is the observation of movements in time. Besides the knowledge of internal systemic changes also the influence of external factors has to be considered, especially volume and structure of the clientel. Simple methodic statements are sufficient analysing the development complexly.--The secular dynamic of the care system has been objected by uniform use of a defined trend-ratio. The influences after the second world war and some actual trends are reported besides the longtime trend explicitly. Finally a workinghypothesis is formulated in regard to the reasons of preterm labour and fetal retardation.
评估特定护理系统结果发展的一个重要前提是对时间动态的观察。除了了解内部系统变化外，还必须考虑外部因素的影响，尤其是客户群体的数量和结构。简单的方法陈述足以对发展进行复杂分析。——护理系统的长期动态一直受到使用固定趋势比率的质疑。除了长期趋势外，还明确报告了第二次世界大战后的影响和一些当前趋势。最后，针对早产和胎儿发育迟缓的原因提出了一个工作假设。
