Abstract: Objective: To analyze the effect of Nursing Delirium Preventive Interventions in ICU (UNDERPIN-ICU) on delirium management in patients after cardiac surgery. Methods: A historical control study was used and 237 patients were selected in CSICU of a tertiary grade A hospital as study participants. The control group (117 cases) received routine nursing measures to prevent delirium, and the intervention group (120 cases) received the UNDERPIN-ICU. The incidence of delirium, duration of mechanical ventilation, ICU stay and hospital stay were compared between the two groups. Results: The incidence of delirium, the duration of mechanical ventilation and ICU stay in the intervention group were significantly shorter than those in the control group (P<0.05). There was no difference in hospitalization time between the two groups (P>0.05). Conclusion: UNDERPIN-ICU can be used for the prevention and management of delirium in patients after cardiac surgery, which is helpful to reduce the incidence of delirium, shorten the time of mechanical ventilation and ICU stay.
