Sleep Apnea Screening Tool Now Available in Thai

A new study published in the journal Sleep and Breathing tested the reliability and validity of the Thai version of the Epworth sleepiness scale (ESS). The ESS is a simple questionnaire used to screen for obstructive sleep apnea (OSA). You can take the ESS here for free.

The researchers also assed the relationship between the ESS score and the severity of OSA.

This study involved 228 subjects - 149 males and 79 females. Thirty-two healthy volunteers and 39 snorers made up the control group. After polysomnography, 126 were diagnosed with obstructive sleep apnea (OSA).

Scores between the two groups were significantly different. The average ESS score for control subjects was 6. In contrast, OSA patients scored about a 10.

Thirty-one OSA patients were successfully treated with CPAP or upper-airway surgery. They took the ESS 3-6 months after treatment. Their ESS scores decreased significantly.

The researchers concluded that the Thai version of the ESS successfully screens for OSA. It can also asses response to treatment. However, the tool was unable to differentiate severity levels of sleep apnea.

The authors recommend combining the Thai ESS with a more comprehensive clinical evaluation.

In April, this blog reported that the ESS was successfully translated into Korean.
