Clinical Research StudyPain Management in Primary Care: A Randomized Controlled Trial of a Computerized Decision Support Tool
Introduction
Chronic pain is a complex condition associated with numerous diagnoses and diverse psychosocial and functional consequences. Most patients with chronic pain are treated by primary care providers (PCPs), who must integrate pain therapies with interventions for disease management and other conditions affecting quality of life while addressing factors associated with health outcomes, such as health literacy and social determinants of illness.1,2 The latter factors may be particularly prevalent in economically disadvantaged populations, like those enrolled in US Federally Qualified Health Center (FQHC) networks.
PCPs may rely on treatment guidelines to implement best practices in pain management. These guidelines change over time, however, and rarely reflect the challenges encountered in specific treatment settings. PCPs may benefit from improved access to setting-specific and up-to-date pain management guidelines.
Recent work suggests that technology-enabled decision support tools are useful to promote guideline-informed practices for complex clinical conditions.3,4 These tools can be customized for the FQHC setting and offer point-of-care information that could potentially improve pain-related outcomes.

Methods
We developed an electronic health record (EHR)-based decision support tool for pain management by PCPs in an FQHC—the Pain Management Support System–Primary Care (PMSS-PC)—and evaluated whether practice level access to the tool plus education improved pain outcomes.
Results
A total of 615 patients were screened, 562 were eligible, and 529 consented; one was subsequently excluded due to age <18 years. The analysis sample included 256 patients receiving care in the early implementation practices and 272 patients receiving care in the delayed implementation practices. Between Time 0 and Time 1, 103 patients were lost to follow-up, including 46 who were receiving care in the early implementation practices and 57 who were receiving care in the delayed implementation
Discussion
We designed an EHR-based decision support tool for pain management for PCPs in an FQHC network and evaluated the tool and accompanying education in a randomized wait-list controlled trial. The trial evaluated the hypothesis that a practice-level intervention would garner positive patient-level pain outcomes22 and that this improvement would be associated with clinician use of the tool.
The trial revealed that one important outcome, worst pain intensity, significantly improved for 6 months after
Conclusion
Although a practice-level intervention comprising an EHR-based decision support tool-plus-education improved worst pain in a population with chronic pain served by an FQHC network, the improvement could not be attributed to use of the technology. This study does not support continued development of the PMSS-PC, but underscores the need for additional research to identify the most salient determinants of practice change and the development of new strategies to improve pain management in primary
