The Epworth Sleepiness Scale: Minimum Clinically Important Difference in Obstructive Sleep Apnea

In a prospective service evaluation of 125 consecutive patients with obstructive sleep apnea syndrome (apnea-hypopnea index [4], or >4% oxygen desaturation index, >7.5 events/h, and symptoms of daytime tiredness and hypersomnolence) offered continuous positive airway pressure (CPAP), ESS was m...

Description
Summary:In a prospective service evaluation of 125 consecutive patients with obstructive sleep apnea syndrome (apnea-hypopnea index [4], or >4% oxygen desaturation index, >7.5 events/h, and symptoms of daytime tiredness and hypersomnolence) offered continuous positive airway pressure (CPAP), ESS was measured at baseline and follow-up (3-months post-CPAP initiation). [...]few patients reported deterioration in their daytime sleepiness; hence, our data estimate the minimum clinically important improvement rather than the true MCID of the ESS. A multicentre randomised controlled trial and economic evaluation of continuous positive airway pressure for the treatment of obstructive sleep apnoea syndrome in older people: PREDICT.
