Summary
The STOP-BANG score is a more effective screening tool for obstructive sleep apnea (OSA) than the Epworth Sleepiness Scale (ESS). Early OSA screening improves sleep quality and reduces health risks.
Area of Science:
- Sleep Medicine
- Respiratory Medicine
- Diagnostic Screening
Background:
- Obstructive sleep apnea (OSA) is a prevalent sleep-breathing disorder with significant health implications.
- Accurate and accessible screening methods are crucial for early detection and prevention of OSA complications.
Purpose of the Study:
- To compare the diagnostic accuracy of the STOP-BANG score and the Epworth Sleepiness Scale (ESS) in screening patients suspected of OSA.
- To evaluate the sensitivity, specificity, and predictive values of these two questionnaires against polysomnography (PSG).
Main Methods:
- Sixty-five patients with suspected OSA were enrolled.
- Data collection included medical history, physical examination, anthropometry, STOP-BANG questionnaire, ESS questionnaire, and overnight polysomnography (PSG).
- Statistical analysis focused on comparing the performance metrics of the STOP-BANG score and ESS.
Main Results:
- The STOP-BANG questionnaire demonstrated higher sensitivity (91.23%) compared to ESS (70.18%) for OSA detection.
- Both questionnaires showed similar specificity (75%).
- Positive predictive values were high for both (STOP-BANG: 96.30%, ESS: 95.20%), while negative predictive values differed significantly (STOP-BANG: 54.50%, ESS: 26.10%).
Conclusions:
- The STOP-BANG score is a superior screening tool for obstructive sleep apnea compared to the ESS.
- Enhanced screening for OSA is recommended due to its high prevalence and potential for improved patient outcomes with timely treatment.
- Effective screening can lead to better sleep quality and reduced risk of adverse health events.

Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.
Ensuring accuracy in vital sign recordings while prioritizing patient comfort and minimizing anxiety is important.

01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
