How is this different than risk factors the CDC has already posted on their website?
The risk of severe complications from COVID-19 is higher for certain vulnerable populations, particularly people who are elderly, frail, or have multiple chronic conditions.
Identifying who is most vulnerable is not necessarily straightforward. More than 55% of Medicare beneficiaries meet at least one of the risk criteria listed by the CDC. People with the same chronic condition don’t have the same risk, and simple rules can fail to capture complex factors like frailty which can make people more vulnerable to severe infections.
The CV19 Index addresses this complexity at-scale with data that is readily available for more than 40 million Medicare beneficiaries through Blue Button and other transport mechanisms.
What types of risk factors are used in this model?
The CV19 Index uses medical claims data that reflects an individual’s medical history, chronic conditions, comorbidities, prior adverse events, recent medical treatments and procedures, functional limitations, and degree of frailty. It also integrates publicly-available data for several social determinants of health.
The proxy endpoint includes Pneumonia, influenza, acute bronchitis, and other respiratory infections. The endpoints are consistent with WHO guidelines and clinical papers that describe COVID-19 and its impacts.
The specific codes used are International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes that have been mapped to Clinical Classifications Software (CCS) categories.
