    Benefit of adjunctive transoral neuromuscular electrical stimulation with positive airway pressure therapy: a case report
    (American Academy of Sleep Medicine, 2023) Stahl, Stephanie M.; Lenet, Adam; Sigua, Ninotchka Liban; Medicine, School of Medicine
    Combination positive airway pressure therapy and daytime transoral neuromuscular electrical stimulation in the treatment of sleep apnea has not been reported in the literature. We present a case of a patient with poorly controlled sleep apnea despite bilevel positive airway pressure. Adjunctive therapy with daytime neuromuscular electrical stimulation resulted in dramatic reduction of the apnea-hypopnea index with significant improvement in patient's symptoms.

    Economic Assessment of 4 Approaches to the Diagnosis and Initial Treatment of Sleep Apnea
    (American Association for Respiratory Care, 2018-01) Bravata, Dawn M.; Lightner, Nancy; Yaggi, H. Klar; Miech, Edward J.; Medicine, School of Medicine
    BACKGROUND: A dilemma faced by health-care administrators is that need greatly outstrips capacity for diagnosing and treating sleep apnea, with such decisions carrying significant economic consequences. Our objective was to develop an economic model to estimate the relative costs of 4 approaches for diagnosis and initial treatment of sleep apnea. METHODS: The analysis consisted of developing a mathematical model depicting possible diagnostic and treatment approaches to the care of patients with sleep apnea; developing 4 clinical scenarios to describe distinct approaches to the management of sleep apnea patients (in-laboratory, unattended, direct-to-autotitrating PAP [auto-PAP], and mixed); and identifying costs associated with each scenario. We created a hypothetical cohort of 1,000 patients with 85% prevalence of sleep apnea to generate cost estimates. RESULTS: The driver of per-patient costs was the total number of sleep studies, which varied widely across scenarios: from 425 for the direct-to-auto-PAP approach to 1,441 in the unattended approach. The scenarios also differed in per-patient costs: Per-patient costs excluding facility startup costs were $456 for direct-to-auto-PAP, $913 for in-laboratory, $991 for mixed, and $1,090 for unattended. CONCLUSIONS: Approaches to diagnosing and treating sleep apnea that emphasized early application of auto-PAP had lower per-patient costs.

    Reducing cardiovascular risk through treatment of obstructive sleep apnea: 2 methodological approaches
    (Elsevier, 2016-02) Yaggi, Klar; Mittleman, Murray A.; Bravata, Dawn M.; Concato, John; Ware, James; Stoney, Catherine M.; Redline, Susan; Department of Medicine, IU School of Medicine
    Obstructive sleep apnea (OSA) significantly impacts cardiovascular health, demonstrated by observational investigations showing an independently increased risk of ischemic heart disease, diabetes, hypertension, congestive heart failure, acute coronary syndrome, stroke, cardiovascular mortality, and all-cause mortality. Positive airway pressure (PAP), a medical therapy for sleep apnea, reverses airway obstruction and may help reduce cardiovascular risk. Prior to planning large phase III randomized controlled trials to test the impact of PAP on cardiovascular outcomes, several gaps in knowledge need to be addressed. This article describes 2 independent studies that worked collaboratively to fill these gaps. The populations, design features, and relative benefits/challenges of the 2 studies (SleepTight and BestAIR) are described. Both studies were encouraged to have multidisciplinary teams with expertise in behavioral interventions to improve PAP compliance. Both studies provide key information that will be useful to the research community in future large-scale, event-driven, randomized trials to evaluate the efficacy and/or effectiveness of strategies to identify and treat significant OSA for decreasing risk of major adverse cardiovascular events in high-risk patients.
