Abstract
Excessive daytime sleepiness (EDS) is a complaint affecting half of patients with obstructive sleep apnea (OSA) and can persist in some patients despite normalization of breathing, oxygenation, and sleep quality with primary OSA therapy, such as continuous positive airway pressure (CPAP). EDS is often overlooked and underdiscussed in the primary care setting and in the follow-up of CPAP-treated patients due to difficult assessment of such a multidimensional symptom. This review aims to provide suggestions for procedures that can be implemented into routine clinical practice to identify, evaluate, and manage EDS in patients with OSA, including how to appropriately use various self-report and objective assessments along the clinical pathway. In addition, examples of when it is appropriate for a healthcare provider to refer a patient to a sleep specialist for evaluation are discussed. Despite certain limitations of this method, healthcare professionals (HCPs) should screen all patients diagnosed with OSA for EDS with the Epworth Sleepiness Scale. If a patient is suspected of having EDS, it needs to be confirmed that the underlying airway obstruction is being optimally treated with CPAP or another OSA primary treatment. If the patient continues to experience EDS despite adherence to primary OSA therapy, the treating clinician should review the patient in clinic and, when appropriate, using questionnaires, physical exams, laboratory tests, or objective assessments to rule out other potential causes of EDS. After a differential diagnosis of residual EDS has been established, the clinician may consider pharmacologic treatment which may include a wake-promoting agent.
