Screening for Impaired Visual Acuity in Older Adults: US Preventive Services Task Force Recommendation Statement
Annals of internal medicine (Impact Factor: 17.81). 07/2009; 151(1):37-43.
Description: Update of the 1996 U.S. Preventive Services Task Force (USPSTF) recommendation statement on screening for visual impairment. Methods: The USPSTF reviewed evidence published since its last review on screening adults 65 years or older in the primary care setting for visual acuity impairment associated with uncorrected refractive errors, cataracts, and age-related macular degeneration. Recommendation: The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for visual acuity for the improvement of outcomes in older adults.

ABSTRACT: The average age of the US homeless population is increasing. Little is known about the prevalence of geriatric syndromes in older homeless adults. To determine the prevalence of common geriatric syndromes in a sample of older homeless adults, and to compare these prevalences to those reported in the general older population. Cross-sectional. Two hundred and forty-seven homeless adults aged 50-69 recruited from eight homeless shelters in Boston, MA. Interviews and examinations for geriatric syndromes, including functional impairment, cognitive impairment, frailty, depression, hearing impairment, visual impairment, and urinary incontinence. The prevalences of these syndromes in the homeless cohort were compared to those reported in three population-based cohorts. The mean age of the homeless cohort was 56.0 years, and 19.8% were women. Thirty percent of subjects reported difficulty performing at least one activity of daily living, and 53.2% fell in the prior year. Cognitive impairment, defined as a Mini-Mental State Examination score <24, was present in 24.3% of participants; impaired executive function, defined as a Trail Making Test Part B duration >1.5 standard deviations above population-based norms, was present in 28.3% of participants. Sixteen percent of subjects met criteria for frailty, and 39.8% had major depression, defined as a score ≥10 on the Patient Health Questionnaire 9. Self-reported hearing and visual impairment was present among 29.7% and 30.0% of subjects, respectively. Urinary incontinence was reported by 49.8% of subjects. After multivariate adjustment for demographic characteristics, homeless adults were more likely to have functional impairment, frailty, depression, visual impairment and urinary incontinence compared to three population-based cohorts of older persons. Geriatric syndromes that are potentially amenable to treatment are common in older homeless adults, and are experienced at higher rates than in the general older population.
