How this fits in

Multimorbidity is associated with poorer health outcomes and greater care needs in those with COVID-19, flu, and other infections. A reliable measure of multimorbidity, such as the Cambridge Multimorbidity Score (CMMS), is needed to support infectious disease epidemiology and other research based on routine data that have their key data recorded using SNOMED CT (Systematized Nomenclature of Medicine — Clinical Terms). A modified version of the CMMS was developed and validated using SNOMED CT, which is more widely used internationally than the Read terminology used for the original version and with an extended age range that the CMMS can be applied to. The unadjusted 21-condition model performed similarly to the original CMMS in predicting mortality with excellent discrimination and reasonable calibration.
