We have received funding to evaluate the cost-effectiveness of two new models of delivery of vestibular rehabilitation. Our primary aim is to test the hypothesis that provision of the self-help booklet teaching vestibular rehabilitation exercises, with up to one hour of remote telephone support from an expert vestibular therapist, will be more effective than routine care in reducing symptoms (and therefore also disability and handicap) in dizzy patients in primary care. We will also explore the extent to which patients may benefit from provision of the self-help booklet without support. We will determine whether these models of delivery are less costly than routine care of dizzy patients, as they should reduce the number of patients seeking referral to secondary care for unnecessary assessments.
