Psychiatric illness in the elderly. A comparison of GP records and survey findings

The GP records of 200 elderly people living at home were scrutinized and estimation made of physical and psychiatric disability. These estimations were compared with those made independently by a psychiatrist interviewing the subjects at home. There was a reasonable agreement between the two assessments of functional disorder and between the two assessments of physical disabilities. Whereas the survey psychiatrist's diagnoses of mental disorder correlated positively with the presence of physical illness, this did not hold for those considered to have evidence of psychiatric illness using GP records alone. The duration of a positive psychiatric history obtained from GP records was consistent with a discrimination between late onset (recent) and chronic neurosis.
