BackgroundThere is limited on the risk factors and mortality in patients with delirium from India.AimThis study aimed to evaluate the risk factors associated with delirium and inpatient mortality rates of patients diagnosed with delirium by psychiatry consultation liaison services.Materials And MethodsThree hundred and thirty-one patients diagnosed as delirium by the psychiatry consultation liaison services were examined on standardized instruments: Delirium Rating Scale Revised 98 version (DRS-R-98), amended Delirium Motor Symptom Scale (DMSS), Delirium Etiology Checklist (DEC), Charlson Comorbidity index, and a checklist for assessment of risk factors.ResultsMore than three medications as a risk factor and metabolic/endocrine disturbances as cause were observed to play largest role in development of delirium. The inpatient mortality rate was 12.4%. Compared to the survivor group, those who died were more likely to be young (<65 years), had significantly high rate of alcohol dependence and were more frequently restrained prior to development of delirium; of these only age <65 years and use of restraints emerged as the significant predictors of mortality in regression analysis.ConclusionAge and use of restraints appears to be an important predictor mortality in patients with delirium.
