Should medical screening of the elderly population be promoted?
This article reviews the history of screening in the elderly, the conditions that should be considered, whether or not screening in the elderly is of benefit, whether we should look for disability or diseases and where screening should take place. Thirteen conditions are discussed: hearing loss and anaemia in some detail. Both disability and precise diagnostic criteria are considered. The place where screening is best carried out depends on the mobility of the subject and the nature of the particular screening tests selected for the 13 conditions. The desirability of screening was assessed on the following criteria: prevalence of the condition, severity of the problem, acceptability by the patient of the screening test, false positive rate, consequences of making a false positive diagnosis, the false negative rate and the consequences of this error, the effect of treatment, the cost of the screening test and the burden on the health services produced by the screening test. The criteria were scored 1-5 on a scale defined for each assessment, with higher scores favouring screening. We provide evidence that screening may be worthwhile for: need for chiropody, varicose veins/ulcer, hearing loss, obesity, visual impairment, hypothyroidism, hypertension, anaemia and diabetes mellitus. However, the assessments discussed in this paper need to be tested prospectively in randomised controlled trials.
