Addressing obstructive sleep apnea in the emergency department

Area of Science:

• Medical Science
• Public Health

Background:

• Obstructive sleep apnea (OSA) is a widespread and serious condition, often overlooked and undertreated.
• It stems from pharyngeal collapse and weakened dilator muscles, leading to significant health risks and mortality.
• OSA is a public health concern, contributing to accidents with substantial societal costs.

Purpose of the Study:

• To inform emergency physicians about OSA's causes, prevalence, diagnosis, and management.
• To outline diagnostic strategies and interventions feasible in the emergency department (ED).

Main Methods:

• Review of OSA pathophysiology, epidemiology, and diagnostic criteria.
• Discussion of emergency department-based screening and referral protocols.
• Identification of lifestyle and medication recommendations for OSA patients.

Main Results:

• Emergency physicians can significantly aid in recognizing and referring patients with potential OSA.
• Targeted history taking, physical exams, or structured evaluations can identify at-risk individuals.
• ED interventions include referral for diagnosis and advising on weight loss, alcohol moderation, and smoking cessation.

Conclusions:

• OSA is prevalent and underdiagnosed in the US, particularly among patients without regular primary care.
• Emergency physicians are crucial in identifying at-risk individuals for OSA.
• Referral for diagnostic workup and providing initial recommendations are key roles for emergency physicians in managing OSA.
