Objective sensor data can…

• focus attention on the right behaviors

• build trust (or distrust) in the patient’s self-reports

• act as a trigger for the optimal level of contact

• make the office encounter more collaborative

“data interventions”• Different stakeholders need different

views of data

• Timeliness of data is critical

• Show data that is interpretable & actionable
