N2  - PURPOSE: To assess whether visual impairment at baseline is an independent contributor to subsequent nursing home placement during a 6-year follow-up. METHODS: 3654 non-institutionalised people aged 49+ years (82.4% of those eligible) who participated in baseline examinations of the Blue Mountains Eye Study (1992-94) were followed during 1997-99. Presenting visual acuity was measured with current glasses and a standardised refraction performed. We defined visual impairment as visual acuity reduced to <or=20/40. Permanent nursing home admissions during follow-up were confirmed by the regional Aged Care Assessment Team and government subsidy payment records. RESULTS: At baseline, 511 participants had presenting visual impairment. After refraction, vision improved to 20/30 or better in 346 persons (68%, "correctable"), while 165 (32%) remained visually impaired. During follow-up, 162 study participants (5.0%) were admitted permanently to a nursing home. The age-adjusted 6-year incidence was 3.6% for participants with normal vision, 16.2% for those with visual impairment after best correction and 8.1% for those with "correctable" visual impairment. After adjusting for non-cognitive factors that predicted nursing home placement, the relative risk (RR) for nursing home admission among persons with visual impairment after best correction was 1.8 (95% CI 1.1-2.9). A similar magnitude of association was found among persons with "correctable" visual impairment (RR 2.1, 95% CI 1.4-3.1). For each line of reduction in presenting visual acuity at baseline, there was a 7% increased risk of subsequent nursing home placement. CONCLUSIONS: This study suggests that decreased vision may be a marker or contributing factor to subsequent nursing home placement in general older populations.<p /> <p>Language: en</p>
