Background: Obstructive Sleep Apnea (OSA) is the primary type of sleep disorder that presents several clinical disorders. These disorders vary from simple complaints such as fatigue and lack of concentration. Some other complaints could be worse and more serious such as personality changes and heart diseases. Nevertheless, it is generally undetected, posing a significant burden on society. The most often used confirmative tool to identify patients suffering from OSA is Polysomnography (PSG), whereas its favorable treatment method is Continuous Positive Airway Pressure (CPAP). However, not every patient has access to a sleep center for detection nor has the money to own a CPAP machine. Primary health care professionals play an essential role in identifying those patients who suffer from OSA due to their first contact with patients in primary health care settings. Objective: The focus of this review paper is providing an overview of obstructive sleep apnea, OSA detection, treatment approaches, and most of all, the role of primary health care professionals in detecting, treating, or referring OSA patients. Methodology: Google Scholar search was used for articles selection using the keywords obstructive sleep apnea, OSA evaluation, diagnosis, and management. Another search was about the societal and economic burden of OSA. Also, the search comprised of the role of primary health care professionals on detection and management of OSA. Conclusion: primary health care providers play a significant role in detecting and treating OSA. They are the first contact that patients go to when sick. The high cost of detecting and treating obstructive sleep apnea may further contribute to late detection, complications deterioration, and decreasing referral and follow-ups. Increasing awareness of the primary health care providers would help to avoid such consequences. OSA remains a public health condition that requires more attention, identification, and more directed research.
