Background: There is limited on the risk factors and mortality in patients with delirium from India. Aim: This 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 Methods: Three 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. Results: More 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. Conclusion: Age and use of restraints appears to be an important predictor mortality in patients with delirium.
