This dissertation uses an existing data source from the Cleveland Clinic's Chronic Pain Rehabilitation Program (CPRP) to describe factors predicting attrition and failure in interdisciplinary pain care, as well as to use the evidence basis from interdisciplinary pain care to translate to concrete policy strategies for use in primary care. The dissertation has three aims: build a model describing factors that patient attrition in an interdisciplinary pain rehabilitation program using the patient data registry at the CPRP, build a nomogram to predict program failure in a comprehensive chronic pain rehabilitation program, using the CPRP patient data registry and examine the evidence basis for interdisciplinary pain care interventions to suggest focused near-term strategies for implementation of the primary care recommendations in the Institute of Medicine's report Relieving Pain in America. Four factors predictive of program attrition in the CPRP were identified: marital status, IQ, chemical dependence and clinician assessed depression. After imputation, variable selection using Harrrell's `model approximation' method and bootstrap validation of the model were used to develop a nomogram to predict program failure. The final nomogram contained ten variables: marital status, IQ, hours rest/day, smoking, chemical dependence, University of Alabama Pain Behavior Scale, anxiety diagnosis, Pain Disability Index, pain duration (years), and the depression subscale of the Depression, Anxiety, and Stress Scale. The model validation results showed the pooled C-statistic=.794 (.722-.803), r2=.226, and shrinkage factor=.97. Interdisciplinary pain care strategies can provide the evidence base for primary care providers to respond to the recommendations from the IOM. Primary care providers and health systems can use evidence based practice to implement these recommendations in the near-term by: changing screening and evaluation of chronic pain, partnering with community stakeholde (open full item for complete abstract)
