Ms Sanja Lujic
Administrative hospital data is commonly used in risk adjustment but the degree to which it is complete and accurate is unclear. This talk will outline the findings from a study using data linkage of a large scale survey and administrative data, examining the agreement between self-reported and coded diagnoses; quantifying the amount of between-hospital variation in this agreement and identifying patient- and hospital-level characteristics that predict higher or lower levels of agreement.
