Psychiatric morbidity in elderly surgical patients

Abstract

One hundred patients aged 65 and over were psychiatrically assessed before and in the first week after elective surgery. Thirteen were psychiatrically ill before operation and 21 developed post-operative illness. Post-operative confusional states (14 patients) were associated with physical complications but not with environmental or pre-operative psychiatric variables. Affective disorders either improved following successful surgery (5 patients) persisted or developed after operation in association with continuing physical illness (6 patients).
