Are at-home sleep studies performed using portable monitors (PMs) as effective at diagnosing obstructive sleep apnea (OSA) in adults as sleep laboratory-based polysomnography (PSG)?

Abstract: UNLABELLED: RESIDENCY PROGRAM: University of Oklahoma Health Sciences Center, Department of Family and Preventive Medicine, Oklahoma City, OK. ANSWER: In patients with suspected OSA, it is reasonable to use PMs if the patient has a high pretest probability (based on an Epworth Sleepiness Scale (ESS) ≥10 and clinical symptoms*) without significant co-morbid heart disease or other sleep disorders and he/she is able to prove competency in setting up the home equipment properly without assistance. However, if the patient has a negative PM, it is standard to perform PSG as it appears approximately 20% will have a false negative PM. (*Clinical symptoms include snoring, witnessed apneas, obesity, pulmonary hypertension, refractory hypertension, morning headaches, increased neck circumference-->17 inches in men, >16 inches in women--daytime sleepiness.) LEVEL OF EVIDENCE FOR THE ANSWER: A. SEARCH TERMS: obstructive sleep apnea, polysomnography, portable home monitors, efficacy. INCLUSION CRITERIA: polysomnography, ambulatory, adults, humans. ESCLUSION CRITERIA: children.
