A Study of Interventions to Reduce Disability From Visual Loss in Nursing Home Residents
This trial is active, not recruiting.
|Conditions||cataract, refractive error, low vision|
|Treatment||visual impairment interventions|
|Sponsor||Johns Hopkins University|
|Collaborator||National Institutes of Health (NIH)|
|Start date||June 1999|
|End date||June 2002|
|Trial size||1600 participants|
|Trial identifier||NCT00348621, RO1AG15812|
The purpose of this clinical trial is to determine if interventions within the nursing home to restore vision, or cope with visual loss, in residents with visual impairment result in improvement or less decline in mobility scores, and socialization scores, compared to residents with visual impairment in nursing homes with no such intervention.We hypothesized that nursing home residents with visual loss who receive cataract surgery, or refractive correction, or low vision aids would have have better socialization scores and mobility scores at 6 months and 12 months compared to nursing home residents with visual impairment who are advised to seek services, but have no specific program.
|Endpoint classification||efficacy study|
|Intervention model||parallel assignment|

|Description||The goal of this project was to quantify the impact of visual acuity impairment on socialization and physical function of nursing home residents, and to determine the cost effectiveness of a visual impairment intervention program designed to enhance access to eye care services. To accomplish these aims, we enrolled a complete sample of visually impaired persons from 28 nursing homes in the Lower Eastern Shore of Maryland and Delaware. From the same facilities, we also enrolled a random sample of non-visually impaired residents, with sample size equal to the sample of visually impaired. The group of visually impaired residents was randomized (by facility) to an intervention program or “usual care” group. The intervention program facilitated the utilization of eye care services of the three main causes of visual impairment: refractive error, cataract, and low vision associated with age-related eye diseases. All study groups provided data at baseline, six and twelve months from intervention, and data on eye care utilization, hospitalizations, use of psychoactive medications and mortality collected every other month (bi-monthly). Patients had a screening test of visual acuity, using standard letter/symbol charts, and grating charts. The mental status was tested using the MiniMental State Examination. Social function, physical function, and mobility were assessed through questionnaires asked of nursing home staff familiar with the patient, and the questions were modeled on the Minimum Data Set questions or specially designed for nursing home residents. We compare the mobility scores, and socialization scores, of nursing home residents with visual loss randomized to the intervention homes to the scores of nursing home residents with visual loss randomized to control homes. We use the mobility and socialization scores of those without visual loss at baseline and follow up to compare with the trajectory of decline in those with visual loss.|
