We have included the diagnosis and treatment of IC in patients with vulvodynia as a standard part of our care for patients for the past 5-7 years. Therefore, we plan to continue this as routine care and bill patients' insurance for evaluation and management services as well as bladder instillations and the PST. Our other potential study site(s) will proceed similarly. We seek the support of the National Vulvodynia Association for solely direct costs of research coordinator coverage and fellow stipend support for their work on this study. These direct costs are: Research Coordinator -10 hrs /week for 50 weeks @ 37.60 per hour including benefits = $18,800.00 plus fellow stipend support - 5 hours / week for 50 weeks @ 32.45 per hour including benefits = $8,112.50. Our total request for funding is $26,912.50.
