The Visible Study: A Randomised Trial
The Visible Study: A Randomised Trial
Background
The consequences of falls are immense in terms of suffering, loss of independence, fear of future falls, carer burden, mortality, residential care admissions, and other health care resource usage. The population attributable risks of regular multifocal glasses use are estimated at 35% for any falls, 41% for falls due to trips, 41% for outdoor falls, and 51% for outdoor falls due to trips.
Aims
To determine whether the provision of single-lens distance glasses to elderly multifocal glasses wearers, together with recommendations for wearing them for standing and outdoor activities, can reduce falling rates over a 12 month period.
Methods
An assessor-blinded randomised controlled multi-centre trial will be conducted in 580 community-dwelling fallers aged over 65 years who habitually wear multifocal glasses when walking outside their homes.
Participants in the intervention group will be given a free pair of distance glasses to wear while standing and during outside activities, and will also receive counselling to reinforce the recommendation.
Control participants will receive usual care.
Falls rates will be monitored via falls calendars for 12 months. The impact of the intervention on quality of life, fear of falling, and activities of daily living will also be assessed.
Status/Results
The 18 month recruitment phase began in April 2005. The study is expected to continue for three years.
