To improve responsiveness of care for Medicaid and other underserved patients: use time-to-treat data (i.e., data measuring the time between clinician identifying a need for an appointment and the patient having a scheduled appointment) to identify patterns by which care or engagement with Medicaid patients or other groups of underserved patients has not achieved standard practice guidelines; and with this information, create, implement, and monitor an approach for improvement. This approach may include screening for patient barriers to treatment, especially transportation barriers, and providing resources to improve engagement (e.g., state Medicaid non-emergency medical transportation benefit).
