Sleep medicine

While the Berlin Sleep Questionnaire (BSQ) was developed to identify patients at high risk of having sleep apnea, assessment can be difficult in patients suffering from impaired cognitive functions (i.e., stroke patients). We therefore created a modified version of the questionnaire to be used in patients' bed partners to test whether it could give identical results to the original form of BSQ. ⋯ The bed-partner Berlin questionnaire predicts an RDI>15 with a better sensitivity and specificity than the original questionnaire. It could, therefore, be used in bed partners of patients suspected of obstructive sleep apnea syndrome who cannot fill in the self-reported Berlin questionnaire.
