Cancer Health Empowerment for Living without Pain (Ca-HELP): effects of a tailored education and coaching intervention on pain and impairment

Abstract We aimed to determine the effectiveness of a lay-administered tailored education and coaching (TEC) intervention (aimed at reducing pain misconceptions and enhancing self-efficacy for communicating with physicians) on cancer pain severity, pain-related impairment, and quality of life. Cancer patients with baseline “worst pain” of ⩾4 on a 0–10 scale or at least moderate functional impairment due to pain were randomly assigned to TEC or enhanced usual care (EUC) during a telephone interview conducted in advance of a planned oncology office visit (265 patients randomized to TEC or EUC; 258 completed at least one follow-up). Patients completed questionnaires before and after the visit and were interviewed by telephone at 2, 6, and 12 weeks. Mixed effects regressions were used to evaluate the intervention adjusting for patient, practice, and site characteristics. Compared to EUC, TEC was associated with increased pain communication self-efficacy after the intervention ( P P P  = .01) but not in pain severity (−0.21 points on an 11-point scale, −0.60 to 0.17, P  = .27). The improvement in pain-related impairment was not sustained at 6 and 12 weeks. There were no significant intervention by subgroup interactions ( P  > .10). We conclude that TEC, compared with EUC, resulted in improved pain communication self-efficacy and temporary improvement in pain-related impairment, but no improvement in pain severity.
