Abstract

BACKGROUND. Use of brief screening instruments for detection of psychological morbidity among elderly people is being promoted, although the appropriateness and effectiveness of available instruments have not been evaluated in general practice. AIM. This study set out to determine the outcome of opportunistic use of brief screening instruments for dementia, depression and problem drinking in randomized trials in two group practices in north west London. METHOD. Screening instruments were inserted into a random sample of medical records for people aged 75 years and over in each practice. Medical records of those seen by their general practitioners over a six month period were reviewed for new diagnoses of dementia (or confusion), depression or problem drinking, and the scores obtained on screening instruments noted. The records of all those identified as possibly demented, depressed or drinking heavily were reviewed one year after screening and all relevant referrals and new treatments were noted. RESULTS. In one practice use of screening instruments resulted in a significant increase in the detection of possible dementia, but not of depression. In the second practice screening instruments yielded significantly higher numbers with possible dementia or depression. Heavy drinking was uncommon in either population. There was no difference in the proportions of cases identified by screening instrument or by clinical judgement alone who received treatment or referral. CONCLUSION. These results suggest that in the absence of agreed guidelines and resources, information derived from screening instruments may not alter clinical practice.
