The total share of the match and kappa statistics was 93% and 0.81, respectively. In all six categories, Kappa ranged from 0.51 to 0.84, with the categories of asthma transfers and drug side effects showing only moderate agreement. Table 2 provides a summary of the results for quality agreements and general agreements on reliability within holes. Category-specific Kappa values homogeneity tests suggest statistically significant heterogeneity. It was therefore interesting to look for potential sources of heterogeneity. The data were aggregated and then stratified by Abstractor to compare the degree of match between time 1 and time 2 for each abstractor (Table 3). The agreement as a percentage of abstraction ranged from 79% to 98%, while intra-rater statistics of abstraction ranged from 0.21 to 0.94. Statistics of chi square heterogeneity for the difference between kappas calculated for the 10 separators were also statistically significant (2-238, p < 0.0001), indicating that individual differences in abstraction consistment may be the heterogeneity of all category-specific Kappa values. The intra-rater agreement was also studied for all abstracts, depending on when the diagram was abstract, either at the beginning of the study (for retrospective patient visits before the initial value) or for a 6-month follow-up. Kappa`s statistics were 0.76 (IC 95% 0.73, 0.79) for abstract retrospective diagrams and 0.82 (IC 95%: 0.80, 0.85) for the 6-month follow-up action (data not presented in the tables). For the intra-rater component of the re-abstract study, 110 diagrams were verified and 218 visits from asthma-related patients were included in the comparison of Charter action at time 1 and 2.

For the Intra-Rater agreement, 110 diagrams, randomly selected from 1,433 patients enrolled in ACP countries in eight Ontario municipalities, were retracted by 10 abstractions.
