The OPEN study has two aims: The first is to identify what helps to keep patients involved with a Medicaid chronic pain management program and to identify features of an ideal text-message-based program for people enrolled in the program. The second aim is to develop the text-message-based program (OPENtext), then find out how useful this intervention is compared to a patient navigator intervention (OPENnav) for increasing patient engagement, improving patient's motivation to manage their chronic pain, and improving patient confidence in self-managing their chronic pain condition.
