Study Arms (2)
Intervention Condition
EXPERIMENTALIndividuals using MISTR services receiving an intervention condition.
Control Condition
ACTIVE COMPARATORIndividuals using MISTR services receiving the standard of care.
Interventions
The exact intervention types will be determined based on Aim 1 data analyses that seek to identify the areas that could most benefit from intervention. Possible interventions to be tested include message content, message format, message time of day, and website design.
The exact intervention types will be determined based on Aim 1 data analyses that seek to identify the areas that could most benefit from intervention. Possible interventions to be tested include warm handoffs, personalized messages, and enhanced remote laboratory testing.
MISTR users receive the current standard of care. The standard of care will be updated as impactful interventions are identified.
