Decision Aid Description and Limitations

The myCOVID19VisitRisk Decision Aid provides individuals with a mechanism to assess their level of risk (acquiring and/or death) from COVID-19. Based on the chosen criteria such as age, sex, and pre-existing health conditions, and visit considerations, a risk category of low, moderate, or high will be given. General expert-informed public health guidance on how to visit more safely with others is accompanied with all risk assessment results.

There is a potential for misclassification of a person’s risk since the predictive ability of the decision aid has not been validated and has been developed based on expert consensus. However, careful effort was made to align predictions with existing scientific literature to ensure that risk scores were assigned appropriately.

Supporting literature and data analyses will be revisited at regular intervals to ensure this decision aid remains relevant to current findings and literature. Furthermore, revisions of this decision aid will be considered every 3 months or if new predictors emerge, current predictors are no longer significant, and/or actual hospitalization and death rates change significantly, whichever comes first.
