Investigators will conduct qualitative interviews with patients, providers, and administrators. Goals of the interviews will be: to understand the patient experience in the CPI, including experiences with the navigation approach currently in place; to identify barriers and facilitators to CPI participation; and to learn how technology—especially cell phone text-messaging—could help support pain care and CPI engagement. These interviews will help develop a text-message-based intervention and provide feedback to existing patient navigator programming. Next, investigators will develop and test the text-message patient support intervention that will contain patient-identified topics and concerns that emerge from the qualitative interviews and topic areas discussed by a stakeholder Advisory Board. Theories of behavior change will be used to help with message development, and patients will take part in helping to test and fine-tune the intervention. Last, investigators will compare the text-message and patient navigation interventions in a randomized controlled study with 200 patients over a six-month period. Investigators will see which approach helps patients increase their involvement in the CPI and better manage their chronic pain. If successful, chronic pain patients across Medicaid programs could benefit from use of the patient navigation or the text-message intervention.
