The purpose of this project is to study the out-patient and inpatient utilization and costs associated with tophaceous gout (a classic form of treatment-failure gout), compare these costs to patients with non-tophaceous gout and evaluate health utilities associated with these gout states. The analyses will be conducted in a manner to support a burden of illness type of presentation / manuscript.
- What are the VA health care costs (inpatient and outpatient) for patients with gout compared to those without gout?
- Does health utility, as calculated by SF-6D, differ in patients with gout compared to patients without gout and between tophaceous and non-tophaceous gout?
- What are the relationships between costs and health utility?
- How does the burden of illness differ by subgroups of gout patients (costs and utilities)?
- What are the VA health care costs for patients with tophaceous gout and are they higher than patients with non-tophaceous gout?
Inclusion criteria Patients with and without gout from the Veterans database described above will be included in the analyses for Study aims 1 and 5. This is approximately 3000 gout patients and 67,000 non-gout patients
Patients with SF-36 data from the above cohort will be included in the analyses for Study aims 2-4. This is approximately 1500 gout patients and 38,000 non-gout patients
