Abstract [en]

Background: With the development of the society, assessment of the quality in health care becomes important. The Swedish National Board of Health and Welfare and the Swedish Association of Local Authorities and Regions make a series of yearly reports, Regional comparisons. The league plot and traffic light approach have been used to present a number of indicators for assessing the quality in health care of the hospitals.

Results: For discussing the statistical uncertainty of the rankings and the weakness of the traffic light methods, we use the Monte Carlo procedure to simulate the possible results and describe them. We also get the expected change in the ranking in order to demonstrate the meaningless of the ranking procedure. Moreover, we suggest to use the chi-square test as a new criterion instead of the 'one third' criterion in the traffic light approach used in the reports. Additionally, we modify the chi-square statistics to handle the over-dispersion phenomenon.

Conclusions:The new criterion can be a choice to detect the less well functioning hospital we are interested in when the public want to compare the quality in health care of hospitals in terms of indicators.
