- W2076475598 abstract "To examine the economic burden and health care utilizations of colorectal cancer patients in the U.S. veteran population. A retrospective database analysis was performed using the Veterans Health Administration Medical SAS datasets (01OCT2008-30SEP2012). Patients (≥18 years of age) diagnosed with colorectal cancer (International Classification of Disease 9th Revision Clinical Modification ICD-9-CM codes 153.xx, 154.xx) were identified. The first diagnosis date was designated as the index date. A comparator group was created by categorizing patients without colorectal cancer but of the same age, region, gender and index year, and matching them by baseline Charlson Comorbidity Index. The index date for the comparison group was selected randomly to minimize selection bias. Continuous medical and pharmacy benefits for 1 year pre- and 1 year post-index date were required. One-to-one propensity score matching (PSM) was used to compare the health care costs and utilizations during the follow-up period between the colorectal cancer and comparison groups, adjusted for baseline demographic and clinical characteristics. A total of 75,208 patients were identified for the colorectal cancer and comparison cohorts. After 1:1 PSM, 24,053 patients were matched from each group, and the baseline characteristics were proportionate. Patients diagnosed with colorectal cancer had more health care utilization including inpatient (20.40% vs. 2.61%, p<0.01), emergency room (ER) (15.32% vs. 6.06%, p<0.01), outpatient (99.60% vs. 64.31%, p<0.01) and pharmacy visits (88.30% vs. 66.20%, p<0.01). The higher health care utilization resulted in increased health care costs, including high inpatient ($9,867 vs. $795, p<0.01), ER ($158 vs. $61, p<0.01), outpatient ($5,020 vs. $1,585, p<0.01), pharmacy ($1,345 vs. $523, p<0.01) and total costs ($16,232 vs. $2,903, p<0.01) for patients diagnosed with colorectal cancer compared to patients in the comparison group. Veteran patients diagnosed with colorectal cancer incurred significantly higher health care utilization and costs over a 1-year period compared to patients without colorectal cancer." @default.
