Incidence of Vestibular Dysfunction in Frail Older Adults Attending an Integrated Care Programme for Older Persons (ICPOP)

Background The World Falls Guidelines (2022) recommend a vestibular assessment as part of a multifactorial falls risk assessment in older adults. There is a possibility however, of vestibular dysfunction being overlooked because of no subjective complaints in older fallers i.e. vestibular agnosia. This study aimed to determine the prevalence of vestibular dysfunction in older adults presenting to physiotherapy in Integrated Care Programme for Older Persons (ICPOP) regardless of complaints of dizziness. Methods This was a retrospective observational study of frail older adults attending physiotherapy in ICPOP over a 4-month period. Patients with a falls history or indicators of vestibular dysfunction (e.g. dizziness, reduced balance on turning) were identified for vestibular assessment. Data was collected from a hospital clinical system using Microsoft Excel. This was a retrospective observational study of frail older adults attending physiotherapy in ICPOP over a 4-month period. Patients with a falls history or subjective indicators of vestibular dysfunction (e.g. dizziness, reduced balance on turning) were identified for vestibular assessment. Data was collected from a hospital clinical system using Microsoft Excel. Results A vestibular assessment was carried out on 69% (n=52) of physiotherapy patients with a mean age of 80.9 years and mean Clinical Frailty Score of 5. 75% of patients that underwent a vestibular assessment had vestibular dysfunction with the most prevalent diagnoses being Benign Paroxysmal Positional Vertigo (40%), Unilateral Vestibular Hypofunction (13%) & reduced gain of Vestibulo-Ocular Reflex (13%). 77% of those who tested positively for vestibular dysfunction had a fall within the last 12 months. 48% of those patients that had vestibular dysfunction did not complain of dizziness. Conclusion Almost half of patients with vestibular dysfunction had no dizziness highlighting the incidence of vestibular agnosia. This study highlights the high prevalence of vestibular dysfunction amongst older adults and supports vestibular assessments in older fallers regardless of the presence of dizziness.
