Abstract

Purpose: Health disparities exist according to an individual's place of residence. We evaluated the association between primary area of residence (urban v rural) according to treatment provider (university based v community based) and overall survival in patients with lymphoma and determined whether there are patient groups that could benefit from better coordination of care. Patients and Methods: Population-based, retrospective cohort study of 2,330 patients with centrally confirmed lymphoma from Nebraska and surrounding states and treated by university-based or community-based oncologists from 1982 to 2006. Results: Among urban residents, 321 (14%) were treated by university-based providers (UUB) and 816 (35%) were treated by community-based providers (UCB). Among rural residents, 332 (14%) were treated by university-based providers (RUB), and 861 (37%) were treated by community-based providers (RCB). The relative risk (RR) of death among UUB, UCB, and RUB were not statistically different. However, RCB had a higher risk of death (RR, 1.37; 95% CI, 1.14 to 1.65; P = .01; and RR, 1.26; 95% CI, 1.06 to 1.49; P = .01) when compared with UUB and RUB, respectively. This association was true in both low- and intermediate-risk patients. Among high-risk patients, UCB, RUB, and RCB were all at higher risk of death when compared with UUB. Conclusion: Survival outcomes of patients with lymphoma may be associated with place of residence and treatment provider. High-risk patients from rural areas may benefit from better coordination of care.
