The effect of nonpharmacological training on delirium identification and intervention strategies of intensive care nurses.

Objective: This study aims to investigate the effect of nonpharmacological intervention training on delirium recognition and the intervention strategies of intensive care (ICU) nurses.

Method: This is a quasi-experimental study conducted using a pretest-posttest design. The study sample included a total of 95 patients staying in the medical ICU of a university hospital and 19 nurses working in these units. The data were collected using the Patient and Nurse Introduction, Confusion Assessment Method for the ICU, and Delirium Risk Factors, and Non-pharmacological Interventions in Delirium Prevention Forms.

Results: Delirium was identified in 26.5% and 20.9% of the patients in the pre- and posttraining phase, respectively. Patients with delirium had a longer duration of stay in the ICU, lower mean Glasgow Coma Scale score and a higher number of medications in daily treatment (p<0.05). The risk of delirium increased 8.5-fold by physical restriction and 3.4-fold by the presence of hypo/hypernatremia. The delirium recognition rate of nurses increased from 7.7% to 33.3% in the post-training phase.

Conclusion: Our study results show that training can increase the efficiency of ICU nurses in the management of delirium.
