Evaluation of the effects of quality management over time at a radiology department.
Data concerning the performance of the department, entered on a monthly basis, will be compared with entries in the error report system on the basis of time series analysis (regression models taking seasons and auto-correlation effects into account). The observation period consists of 46 homogeneous monthly time pulses.
Effects of the suggestions and the total number of reports in the quality assurance system on the performance of the department can be observed with a two-month delay. This association is statistically highly significant (p < 0.01) and, because of the procedures used, not attributable to general developmental trends, seasonal fluctuations or autoregressive processes.
Evaluation of quality assurance measures is a well justified demand and should be based on the analysis of data collected from quality assurance systems operating on a continuous basis over a long period of time. The analysis of data from a radiology department shows that quality assurance is reflected in the performance of the department.
评估放射科质量管理随时间产生的效果。
基于时间序列分析（考虑季节和自相关效应的回归模型），将每月录入的科室绩效数据与差错报告系统中的记录进行比较。观察期由46个均匀的月度时间脉冲组成。
质量保证系统中的建议及报告总数对科室绩效产生的效果有两个月的延迟。这种关联在统计学上具有高度显著性（p < 0.01），并且由于所采用的程序，并非归因于一般发展趋势、季节性波动或自回归过程。
对质量保证措施进行评估是合理的要求，且应基于对长期持续运行的质量保证系统所收集数据的分析。对放射科数据的分析表明，质量保证体现在科室绩效中。
