title: Obstructive sleep apnea (OSA) in primary care: evidence-based practice.
abstract: This paper presents data evidence supporting the value of diagnosing and treating obstructive sleep apnea (OSA) in reducing morbidity and mortality, improving comorbid disease processes, and improving patient quality of life. These data are derived from a PubMed-based meta-analysis of recent cost effectiveness, standards of practice, and epidemiological studies of OSA, which are ranked using a hierarchical strength of recommendation taxonomy. Cost and health care utilization data have been calculated for OSA and hypersomnolence as well as for diagnostic testing. Strong evidence (which is indicated by a strength of recommendation rating of "A") exists for the association of adult OSA with obesity, daytime sleepiness, hypertension, and motor vehicular accidents. Strong evidence also exists for requiring full-night or split-night attended polysomnography (PSG) for the diagnosis and treatment of adult OSA and for patients with systolic or diastolic heart failure not responding to optimal medical management. Good evidence (B) exists for the association of adult OSA with congestive heart failure, coronary artery disease, cerebral vascular accidents, metabolic syndrome, and increased mortality. Good evidence also exists to indicate that the nonattended PSG can be used to diagnose sleep breathing disorders, that autotitration systems can be used to titrate continuous positive airway pressure (CPAP) therapy, and that the multiple sleep latency test can be used in the assessment of daytime sleepiness.
