Efficacy of Liaison Education and Environmental Changes on Delirium Incidence in ICU

Delirium is a disorder with disturbance of consciousness, cognitive process. The present study’s aim is to evaluate the efficacy of liaison educational and environmental changes on the delirium rate in ICU patients.
This is a quasi-experimental study on 148 admitted patients (over 18 years of age) in the general ICU. A total of 69 patients in the group before implementing multidisciplinary interventions and 79 patients in the group after multidisciplinary interventions were evaluated. In the case and control group RASS level of consciousness were measured. Scale ICU- CAM (at morning and evening) is used to check the incidence of delirium in the ICU patient. In addition, the demographic questionnaire has been used and delirium duration and the length of hospitalization are also evaluated in both groups. Multifactorial interventions are included as staff physicians and nurses training through a workshop. It should be noted that a 3-hour workshop is used for training of all staff personnel in the ICU ward. The 2nd part is creating environmental intervention in the ICU to decrease delirium in admitted patients.
In this study, 148 patients were studied, 69 patients in the group before implementing multidisciplinary interventions and 79 patients in the group after multidisciplinary interventions were evaluated. Incidence of delirium was 30 (37.97) in intervention and in 50 (72.46) control group (P = 0.01). The mean percent day in ICU patients with delirium was 26.18 ± 35.38 at intervention group and 35.84 ± 39.31 in the control group (P = 0.001).
We found that delirium can be reduced by some intervention, and also medical team orientation about delirium can be help to reduced the incidence; therefore, it is recommended that this factor be evaluated in future study.
