BackgroundPancreatic cancer is a major cause of morbidity and mortality in the Medicare population. Whether the health care burden of pancreatic cancer has changed over the last decade is unknown.MethodsThe authors used Medicare data from 2000 to 2010 to identify beneficiaries aged ≥ 65 years who were hospitalized for the management of pancreatic cancer. Annual trends were estimated for the age-sex-race-adjusted initial hospitalization rate, the age-sex-race-comorbidity-adjusted 1-year mortality rate after initial hospitalization, age-sex-race-comorbidity-adjusted procedure rates, 1-year all-cause rehospitalizations after initial pancreatic cancer hospitalization, and mean inflation-adjusted Medicare payment for initial hospitalization.ResultsA total of 130,728 patients had ≥ 1 hospitalizations for pancreatic cancer and were identified from 56,642,071 beneficiaries during the study period. The age-sex-race-adjusted rate of initial hospitalization for pancreatic cancer was 50 per 100,000 person-years in 2010, representing a 0.5% annual increase since 2000 (95% confidence interval [95% CI], 0.3%-0.7%). In the same period, the age-sex-race-comorbidity-adjusted 1-year mortality rate decreased by 4.4% (95% CI, 3.9%-4.9%), and the age-sex-race-comorbidity-adjusted surgical resection rate increased by 6.9% (95% CI, 6.4%-7.5%). The mean inflation-adjusted Medicare payment for the initial hospitalization decreased, from $14,118 in 2000 to $13,318 in 2010, and the number of 1-year all-cause rehospitalizations after the initial hospitalization increased from 0.75 per patient in 2000 to 0.82 per patient in 2009 (all P < .001).ConclusionsFor Medicare fee-for-service beneficiaries, initial pancreatic cancer hospitalization, surgical resection, and rehospitalization rates increased, but 1-year mortality rates declined over the last decade.© 2013 American Cancer Society.
