This is the first randomised controlled trial assessing the effect of music on delirium after craniotomy.A variety of secondary outcomes, substantiating the onset of delirium and its clinical implications, were collected.Delirium was defined with the Delirium Observation Screening Scale and the Diagnostic and Statistical Manual of Mental Disorders criteria.Due to the nature of the intervention, we did not blind the study, which could have influenced the outcome assessors.The generalisability of the results may be affected by the single-centre design of the study.
