Hospital rankings based on composite quality scores for acute myocardial infarction care vary widely depending on the aggregation method used, highlighting the need for transparency in methodology.
Couralet et al. (2011) conducted an observational in Acute myocardial infarction (n=14,966). Different aggregation methods for composite quality scores vs. Other aggregation methods was evaluated on Variations in hospital rank according to aggregation method. Using different aggregation methods for composite quality scores led to a change in rank for 71% (196 of 275) of hospitals, with agreement between methods ranging from κ=0.20 to 0.84.
