Background. Treatment summaries and follow-up care plan information should be provided to cancer survivors. This study examines the association of receiving summaries and care planswith cancer survivor self-efficacy for chronic illness management, and whether self-efficacy was associated with health care utilization. Methods. Four hundred forty-one cancer survivors (≥2 years from diagnosis and had completed treatment)≥65 years old from 12 cancer centers across 5 states completed telephone surveys. Survivors responded to three questions about receiving a written treatment summary, written follow-up plan, and an explanation of follow-up care plans. Respondents completed the Stanford Chronic Illness Management Self-Efficacy Scale and reported emergency roomvisits and hospitalizations in the past year. Three multiple linear regression models estimated the association of written treatment summary, written follow-up care plan, and verbal explanation of follow-up plan with total self-efficacy score. Log-binomial models estimated the association of self-efficacy scores with emergency room visits and hospitalizations (yes/no). Results. Among survivors, 40% and 35% received a written treatment summary and follow-up care plan, respectively. Seventy-nine percent received an explanation of follow-up care plans. Receiving a verbal explanation of follow-up care instructions was significantly associated with higher self-efficacy scores (β=0.72,p=.009).Higher self-efficacy scores were significantly associated with lower prevalence ratios ofemergency roomvisits (prevalence ratio, 0.92; 95% confidence interval, 0.88-0.97) and hospitalizations (prevalence ratio, 0.94; 95% confidence interval, 0.89-0.99). Conclusion. Explanation of the follow-up care plan, beyond the written component, enhances survivor self-efficacy for managing cancerasachroniccondition-an importantmediator for improving health care utilization outcomes.
