Application of HFMEA Model in ICU Delirium Risk Management of Patients after Cardiac Surgery

To observe the effect of HFMEA model in ICU delirium risk management of patients after cardiac surgery. From May 2022 to May 2024,70 ICU patients after cardiac surgery in our hospital were selected as subjects. According to the random sampling grouping method, the included cases were divided into two groups. One group was given routine ICU delirium risk management (control group, 35 cases), and the other group was given risk management based on HFMEA model (observation group, 35 cases). The delirium score and the incidence of delirium in the two groups were statistically analyzed. The delirium score of the observation group after management was lower than that of the control group, P
