What are the preferred attributes of models used for publicly reported outcomes?
The preferred attributes of models used for publicly reported outcomes include clear and explicit definition of an appropriate patient sample, clinical coherence of model variables, sufficient high-quality and timely data, designation of an appropriate reference time before which covariates are derived and after which outcomes are derived, use of an appropriate outcome and a standardized period of outcome assessment, application of an analytical approach that takes into account the multilevel organization of data, and disclosure of the methods used to compare outcomes, including disclosure of performance or risk-adjustment methodology in derivation and validation samples.
