OBJECTIVE: To use coronary revascularization choice to illustrate the application of a method simulating a treatment's effect on subsequent resource use. DATA SOURCES: Medicare inpatient and outpatient claims from 2002 to 2008 for patients receiving multivessel revascularization for symptomatic coronary disease in 2003-2004. STUDY DESIGN: This retrospective cohort study of 102,877 beneficiaries assessed survival, days in institutional settings, and Medicare payments for up to 6 years following receipt of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). METHODS: A three-part estimator designed to provide robust estimates of a treatment's effect in the setting of mortality and censored follow-up was used. The estimator decomposes the treatment effect into effects attributable to survival differences versus treatment-related intensity of resource use. PRINCIPAL FINDINGS: After adjustment, on average CABG recipients survived 23 days longer, spent an 11 additional days in institutional settings, and had cumulative Medicare payments that were $12,834 higher than PCI recipients. The majority of the differences in institutional days and payments were due to intensity rather than survival effects. CONCLUSIONS: In this example, the survival benefit from CABG was modest and the resource implications were substantial, although further adjustments for treatment selection are needed.

    ABSTRACT: We investigated longitudinal hospitalization outcomes (total charges, hospital days and admissions) among pediatric and adolescent patients with cancer compared with individuals from the general population without cancer using a novel and efficient three-step regression procedure. The statewide Utah Population Database, with linkages to the Utah Cancer Registry, was used to identify 1,651 patients who were diagnosed with cancer from 1996 to 2009 at ages 0 to 21 years. A comparison group of 4,953 same-sex and -age individuals was generated from birth certificates. Claims-based hospitalization data from 1996 to 2012 were retrieved from the Utah Department of Health. Using the regression method, we estimated survival (differences due to survival) and intensity (differences due to resource accumulation) effects of the cancer diagnosis on hospitalization outcomes within 10 years after diagnosis. At 10 years after diagnosis, on average, patients with cancer incurred $51,723 (95% CI, $48,100 to $58,284) more in charges, spent 30 additional days (95% CI, 27.7 to 36.1 days) in the hospital, and had 5.7 (95% CI, 5.4 to 6.4) more admissions than the comparison group. Our analyses showed that the highest hospitalization burden occurred during the first 4 years of diagnosis. Patients with leukemia incurred the greatest hospitalization burden throughout the 10 years from diagnosis. Intensity effects explained the majority of differences in hospital outcomes. Our results suggest that children and adolescents who were diagnosed with cancer in 2014 in the United States will incur over $800 million more in hospital charges than individuals without cancer by 2024. Interventions to reduce this burden should be explored in conjunction with improving health and survival outcomes. Copyright © 2015 by American Society of Clinical Oncology.
