What are the challenges with outcome measures?
The challenges with outcome measures are primarily in the risk-adjustment modeling methods, which, though never perfect, can substantially enhance the ability to compare outcomes across different delivery teams, settings, locations, and systems. Additionally, certain outcomes may be of inarguable importance in PCI but occur rarely, making it difficult to interpret at the individual-provider level due to the small sample size and low-frequency events. Lastly, data sources and data systems often lack adequate granularity to be of meaningful use for attribution of outcomes performance at the level of the individual provider.
