 The purpose of this study was to investigate factors on admission indicating the risk of delirium early after admission in elderly patients who were admitted to hospital for acute-stage medical treatment and experienced rapid environmental changes.

 The subjects were two hundreds of medical inpatients aged 70 years or older, admitted to general hospitals. Of the 200 patients, 21 developed delirium (incidence 10.5%) within 3 days after admission. Logistic regression identified nine variables related to incidence of delirium: alcohol consumption (OR=185.7, p=.019, 95%CI=2.4 to 14515.5), bad falling asleep (OR=159.5, p=.025, 95%CI=1.9 to 13476.6), benzodiazepine (OR=144.8, p=.012, 95%CI=3.0 to 6884.2), anxiety (OR=116.0, p=.020, 95%CI=2.1 to 6434.7), fasting (OR=95.8, p=.024, 95%CI=1.8 to 5090.1), dissatisfaction (OR=68.7, p=.039, 95%CI=1.2 to 3787.6), 200 mg/dl higher of blood sugar (OR=39.9, p=.048, 95%CI=1.0 to 1549.8), disorientation (OR=28.7, p=.019, 95%CI=1.7 to 472.2), and constipation (OR=15.6, p=.033, 95%CI=1.2 to 197.0).

 The risk factors for delirium developed in this research incorporate the nursing perspective that patients as human beings are stimulated and reacting to their environment; this is different from the conventional medical model. The model shows promise for predicting delirium among elderly people admitted to hospitals for acute care and points the way to nursing care to prevent its onset.
