INTRODUCTION: Sleepiness is a frequent complaint and might be a symptom of obstructive sleep apnoea. Our aim was to examine if patient-reported tiredness on either the Epworth Sleepiness Scale or on a visual analogue scale was associated with the Apnoea-Hypopnoea Index. METHODS: We conducted a retrospective database study on 215 patients referred on suspicion of obstructive sleep apnoea. Before cardiorespiratory monitoring, all patients answered the Epworth Sleepiness Scale Questionnaire and rated their tiredness on a visual analogue scale. RESULTS: No correlation was found between the Apnoea-Hypopnoea Index and the Epworth Sleepiness Scale (Spearman's ρ = 0.02) or the visual analogue scale of tiredness (ρ = -0.04). This also applied for a subgroup of patients with an Apnoea-Hypopnoea Index score > 15. CONCLUSIONS: Monosymptomatic patient-reported tiredness should not raise suspicion of obstructive sleep apnoea. Conversely, if obstructive sleep apnoea is suspected, a lack of tiredness should not postpone further evaluation.none. TRIAL REGISTRATION: not relevant.
