There are two arms of the study. Arm 1 will enroll 100 subjects to assist the Ohio Department of Medicaid (ODM) and to provide efficient and effective administration of the Medicaid program. This is an observational and descriptive study that will seek to generate a hypothesis. Due to the small sample size this study will primarily be a feasibility study that will attempt to measure and evaluate differences in the relative costs of the intervention of topical oxygen therapy on this population and subsequently compare outcomes in areas such as overall health improvements and cost effectiveness. The patient population will consist of Medicaid beneficiaries with chronic wounds and below who are enrolled in the United Health Care Community Plan of Ohio (UHC).
