Insights

The Thai version of the pediatric obstructive sleep apnea screening tool (POSAST) is reliable and valid for screening symptomatic children in Thailand. This tool aids in identifying children at risk for moderate to severe obstructive sleep apnea (OSA).

Area of Science:

  • Pediatric Pulmonology
  • Sleep Medicine
  • Clinical Diagnostics

Background:

  • Obstructive sleep apnea (OSA) is common in children but diagnosis requires costly and inaccessible sleep studies.
  • A validated screening tool, the Pediatric OSA Screening Tool (POSAST), exists but needs translation for wider use.
  • Developing accessible screening methods is crucial for early detection and management of pediatric OSA.

Purpose of the Study:

  • To translate the POSAST into Thai.
  • To evaluate the accuracy and test-retest reliability of the Thai POSAST in symptomatic children at risk for OSA.
  • To establish cut-off points for identifying moderate to severe OSA in Thai children.

Main Methods:

  • Prospective cross-sectional cohort study involving pediatric patients referred for suspected OSA.
  • Caregivers completed the Thai POSAST, with re-administration after 2-4 weeks to assess test-retest reliability.
  • Receiver operating characteristic (ROC) curves were used to determine the validity and optimal cut-off scores for diagnosing moderate to severe OSA (Apnea-Hypopnea Index [AHI] ≥ 5 events/h).

Main Results:

  • Excellent test-retest reliability (Pearson correlation coefficient = 0.96) and internal consistency (Cronbach's alpha = 0.82) were observed.
  • An equation-derived score cut-off of 1.9 showed 78.4% sensitivity and 50.0% specificity.
  • A total additive score cut-off of 8 demonstrated 81.1% sensitivity and 52.8% specificity for moderate to severe OSA.

Conclusions:

  • The Thai version of the POSAST demonstrates satisfactory internal consistency and reproducibility.
  • The screening tool exhibits acceptable validity for use in symptomatic Thai children.
  • The Thai POSAST is a suitable instrument for screening Thai children suspected of having OSA.

Sleep Apnea01:21

Sleep 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.
The condition is more prevalent among...

Assessment of Respiration01:23

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
