KCE Reports 81 PROCARE – phase 2 63Figure 16. Mean QI result per centre with at least 10 patients in thedenominator for at least 15 of the 30 measurable QI (prospective cohort).1002590802070Mean QI result (%)6050401510Number of measurable QI302051000The bars represent the mean QI results, while the dots represent the number of measurable QIper centre. A higher mean QI result is associated with better performance. These results arepreliminary, and cannot be used to judge the quality of care.3.2.3.2 Administrative databaseEighty-six centres had at least 10 patients in the denominator for at least 6 of the 10measurable QI, of which 51 centres are involved in the PROCARE project (Figure 17).The mean corrected rank ranged from 0.17 – 0.87. Increasing the minimum number ofpatients in the denominator to 20 (for at least 6 QI), the analysis included 56 centres(39 centres involved in the PROCARE project) (Figure 18). For these 56 centres themean corrected rank ranged from 0.09 – 0.81. Visually, the PROCARE centres arerepresented across the entire spectrum of mean corrected ranks (Figure 17 and Figure18).For the 86 centres with at least 10 patients in the denominator for at least 6 of the 10measurable QI, the mean QI result ranged from 46 – 78% (Figure 19). Increasing theminimum number of patients in the denominator to 20 (for at least 6 QI) did not changethis range (data not shown). Visually, the PROCARE centres tend to be on the right (i.e.‘good’) side of the graph.
