ObjectivesScreening can increase early detection and reduce rates of advanced-stage cancer. Uninsured patients have been shown to have lower rates of screening. Previous studies have shown that uninsured patients and patients with Medicaid present with more advanced stages of cancer. The aim of this study was to measure the effect of insurance status in the setting of a safety-net hospital.MethodsPatients in our tumor registry with a diagnosis of breast or colorectal cancer between 2001 and 2010 were included. On the basis of their insurance status, they were divided into the following groups: Medicaid, Medicare, Medicare age <65 years, commercial, uninsured, and unknown. Cancer stage was recorded for each patient, with stages III and IV considered advanced disease. The primary end point was the rate of advanced disease in each patient group.ResultsA total of 910 patients were included in the study: 836 (91.9%) insured, 54 (5.9%) uninsured, and 20 (2.2%) unknown. Of the insured patients, 301 (36.0%) had Medicaid; 237 (30.7%) of 836 insured patients had advanced disease, compared with 27 (50.0%) of 54 uninsured patients (odds ratio, 1.63; P = .003). Of patients with Medicaid, 83 (27.6%) of 301 had advanced disease, which was not statistically different from patients with other insurance.ConclusionsIn a safety-net hospital, patients with Medicaid had rates of advanced-stage cancer similar to those in patients with other types of insurance. However, patients with no insurance had significantly higher rates of advanced disease. This has significant ramifications in view of the new healthcare law, which will convert many patients from being uninsured to having Medicaid.
