For the "number of follow-up visits" outcome variable, the binary predictor (intervention group) and discrete outcome variable (number of visits) will be evaluated with Wilcoxon-rank sum test for non-normal data. The first visit of a patient to a participating provider for a skin problem is considered the index visit and that provider considered the index provider regardless of the provider seen on any subsequent appointment. Analysis will adhere to the intention-to-treat principle with group assignment determined by randomization regardless of whether VisualDx was deployed for care or not. Problems unresolved at the last contact will be censored as unresolved for the Kaplan-Meier analysis.
