IntroductionIn order to better treat obstructive sleep apnea (OSA) in a more efficient and cost-effective way, a joint program between dental clinics and the sleep medicine clinic was piloted at Fort Hood, Texas. Obstructive sleep apnea negatively affects soldier readiness and deployability, leading to the need to establish a successful and proven workflow to treat these patients with oral appliance therapy (OAT).Materials And MethodsWe performed a retrospective review of a de-identified data set which included 288 patients from July 2016 to July 2020. Projected cost data were obtained from routinely collected sleep clinic positive airway pressure (PAP) data. Data were analyzed to determine treatment success and potential cost savings using OAT versus continuous positive airway pressure (CPAP). Patient workflow including successes and challenges with the program is summarized.ResultsAbout 85.5% of patients met criteria for successful control of their OSA using OAT as treatment. Five patients did not tolerate OAT and switched back to CPAP. A higher (less severe) O2 nadir on diagnostic polysomnography is moderately correlated with OAT success. Diagnostic Apnea-Hypopnea Index was inversely and weakly correlated with success. Two of the major challenges noted in the program were (1) loss of follow-up and (2) the length of time from oral appliance referral to fitting the oral appliance. If this program was successfully implemented at other Defense Health Agency (DHA) medical treatment facility (MTF) markets nationwide, a potential cost savings of over $500,000/year/MTF could be achieved.ConclusionsOral appliance therapy has the potential to increase both readiness and deployability for active duty soldiers. Using baseline O2 nadir can help predict success with OAT patients, determining which patients will benefit from this joint program between the dental and medical sleep clinics. Future studies can aim to establish an evidence-based pathway for clinic testing and follow-up. If this patient workflow is implemented properly, there can be significant cost savings army-wide. This all helps The United States Medical Command (MEDCOM) align with the DHA's Quadruple Aim of increased readiness, better health, better care, and lower cost.© The Association of Military Surgeons of the United States 2021.
