ABSTRACT This article is the first to describe Department of Veterans Affairs (VA) patients' use of Medicaid at a national level. We obtained 1999 national VA enrollment and utilization data, Centers for Medicare and Medicaid Services enrollment and claims, and Medicare information from the VA Information Resource Center. The research team created files for program characteristics and described the VA-Medicaid dually enrolled population, healthcare utilization, and costs. In 1999, VA-Medicaid dual enrollees comprised 10.2% of VA's annual patient load (350,000/3,450,000); 304,000 were veterans. These veterans differed marginally from VA's veteran patients, being on average half a year younger and having 1% fewer males. Dual enrollees with mental health diagnoses and care were almost three times as numerous as long-term care patients; these two groups accounted for ~60% of dual enrollees. Dual enrollees disproportionately included housebound veterans and veterans needing aid and assistance. Half the dual enrollees had 12 months of Medicaid eligibility, and total Federal expenditures per patient not in managed care programs averaged >$18,000 (median >$6,000). Dually enrolled women veterans cost ~55% less than men. Medicaid benefits complement VA and are more accessible in many states. VA researchers need to consider including Medicaid utilization and costs in their studies if they target populations or programs related to long-term care or mental disorders.

    ABSTRACT: The Department of Veterans Affairs (VA) provides nationwide access, lifetime coverage, and an integrated care structure to its enrollees. Those key aspects of VA healthcare-together with data contained in VA's electronic information systems supporting over eight million veterans-provide unique opportunities to study processes, outcomes, and costs of care. Recently, for example, VA data have been used to study outcomes associated with acute postoperative inpatient rehabilitation and care in specialized rehabilitation bed units after lower-limb amputation [1-2], medication adherence and relapse among patients discharged from a VA posttraumatic stress disorder (PTSD) treatment program [3], the provision and costs of assistive technology devices to veterans after stroke [4], and use of mental health services by veterans disabled by auditory disorders [5].

    ABSTRACT: Background Triple-negative breast cancer (TNBC) is a subset of breast cancer. Health care cost and utilization data for TNBC are lacking. Objective We examined differences between metastatic TNBC and metastatic non-TNBC in survival and health care costs and utilization. Methods This retrospective analysis of metastatic TNBC (n = 134) and metastatic non-TNBC (n = 445) used a proprietary oncology registry, the Impact Intelligence Oncology Management registry database, linked with health insurance claims and social security mortality data. Results We found metastatic patients whose breast cancer is triple negative to be younger (56.49 vs 59.24 years), to be more likely to have recurrent disease (64.93 vs 45.39%), and to have greater mortality vs metastatic non-TNBC patients (67.16 vs 50.79%) (all P < .05). Recurrent patients with metastatic TNBC have the highest risk of death (HR = 1.9; P < .001), whereas survival was greatest for de novo metastatic non-TNBC. Patients with metastatic TNBC had more all-cause annual hospitalizations, more hospitalized days, and higher total costs vs metastatic non-TNBC. Annual payer's total costs, annual payer's inpatient costs, cancer-related hospitalizations, and cancer-related inpatient costs also were greater among patients with metastatic TNBC. Limitations While the study spans slightly more than 2 years, 5-10 years would have been preferable to achieve a full clinical profile of indexed patients. The database also omitted factors that potentially confound the results, such as race and socioeconomic status. Conclusions Metastatic TNBC is associated with significant burden of disease and higher health care utilization vs metastatic non-TNBC, which may be due in part to the aggressive clinical course of the disease.
