Specialized survivor clinic attendance is associated with decreased rates of emergency department visits in adult survivors of childhood cancer

Abstract

BACKGROUND Survivors of childhood cancer are at considerable risk of experiencing treatment-related adverse health outcomes. To provide survivors with specialized care focused on these risks during adulthood, the government of Ontario funded a provincial network of specialized survivor clinics in 1999. The aim of this study was to determine whether prior attendance at survivor clinics by adult survivors of childhood cancer was associated with rates of emergency department (ED) visits. METHODS This was a population-based, retrospective cohort study using multiple linked administrative health databases. The cohort consisted of all adult survivors of childhood cancer diagnosed between January 1, 1986 and December 31, 2005 in Ontario, Canada. A recurrent event regression model was used to evaluate the association between prior attendance at survivor clinics and the rate of ED visits; adjustments were made for individual, demographic, treatment, and provider characteristics. RESULTS The study consisted of 3912 adult survivors of childhood cancer. Individuals who had at least 1 prior visit to a survivor clinic had a 19% decreased rate of ED visits in comparison with individuals who had not visited a survivor clinic (adjusted relative rate, 0.81; 95% confidence interval, 0.78-0.85). Each additional prior visit to a survivor clinic was associated with a 5% decrease in the rate of ED visits (adjusted relative rate, 0.95; 95% confidence interval, 0.93-0.96). These results were independent of whether or not survivors received care from a primary care physician. CONCLUSIONS Attendance at a specialized survivor clinic was significantly associated with decreased ED visits among adult survivors of childhood cancer. Cancer 2015;121:4389-97.
