Classification of substandard factors in perinatal care: development and multidisciplinary inter-rater agreement of the Groningen-system

Table 2 Uncorrected agreement on the classification of 284 SSF’s in main categories and subcategories of the classification of substandard factors, classified by two classifier groups (CDG* and ICG^¥) separately and combined

^£One disagreement on allocation per group acceptable, i.e. CDG 7 out of 8, ICG 4 out of 5. Two disagreements on allocation in CDG and ICG together acceptable, i.e. 11 out of 13
^*CDG = Classification Development Group (8 allocators)
^¥ICG = Independent Classification Group (5 allocators)
^§n = total number of substandard factors (main categories). For subcategories : only the substandard factors with 100 % uncorrected agreement in the main category were used (CDG 140/194). For subcategory 2: only the substandard factors with 100 % uncorrected agreement in main category “medical practice” and in subcategory 1 were used (CDG 14/61). The same principle was used for ICG and ICG + ICG together
