Sleep disordered breathing in primary care medicine

Area of Science:

• Sleep Medicine
• Primary Care Medicine
• Public Health

Background:

• Sleep disorders are underdiagnosed in primary care settings.
• Untreated sleep disorders lead to significant human and socioeconomic costs.
• Primary care physicians require enhanced training in sleep medicine.

Purpose of the Study:

• To assess the prevalence of risk for sleep-disordered breathing (SDB) in a primary care population.
• To identify common symptoms associated with SDB, PLMD, and insomnia.
• To evaluate the utility of the Epworth sleepiness scale in primary care.

Main Methods:

• A validated questionnaire assessing SDB, PLMD, and insomnia symptoms was administered to 852 primary care patients.
• A polygraphically validated algorithm identified patients with high suspicion of SDB.
• Data analysis included demographic factors and symptom reporting.

Main Results:

• 20% of patients had a high risk for SDB, 18.5% for PLMD, and 25% for insomnia.
• Daytime sleepiness and fatigue were common symptoms across all assessed sleep disorders.
• Snoring was reported by 50% of patients, with 31% snoring nightly. SDB was more prevalent in men and associated with higher BMI.

Conclusions:

• Sleep-disordered breathing, PLMD, and insomnia are highly prevalent in primary care.
• Integrating sleep disorder assessment into routine primary care history-taking is essential.
• Further research is needed to optimize sleepiness assessment tools in primary care settings.
