Summary

Institut national de santé publique du Québec I Evaluation of the performance of designated screening centers of the Programme québécois de dépistage du cancer du sein (PQDCS): description of the methods In order to compare the performance of each individual centre with that of Quebec as a whole, each observed rate/expected rate ratio (and its confidence interval) is multiplied by the value of the [...] That is: measure the performance of DSCs, analyze the evolution of each DSC’s performance over time, and compare the performance of each DSC with the average performance of the Quebec program as a whole, as well as with the PQDCS target. [...] Institut national de santé publique du Québec 5 Evaluation of the performance of designated screening centers of the Programme québécois de dépistage du cancer du sein (PQDCS): description of the methods 3. METHODOLOGY The proposed methods of analysis are illustrated using the breast cancer detection rate as the performance indicator of interest. [...] Direct standardization consists of applying the category distribution of the adjustment variable(s) for the reference population to the rates by category of the adjustment variable(s) for the study populations. [...] Indirect standardization consists of applying the rates by category of the adjustment variable(s) for the reference population to the distribution by category of the adjustment variable(s) for the study populations.
