    Author: Salomonowitz E, Strunk G, Stadlbauer A, Dürselen L, Güntert B.
    Journal: Rofo; 2008 Sep; 180(9):798-803. PubMed ID: 18600604.
    Abstract:
    PURPOSE: Evaluation of the effects of quality management over time at a radiology department. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
