Analysis of the Impact of Psychological Nursing Intervention on Psychological Status and All-Cause Mortality in ICU Patients with High Nutritional Risk.

Background: Intensive Care Unit (ICU) patients with nutritional risk often face both physical and psychological burden, with anxiety and depression being the most common ones, which may affect their clinical outcomes. Objective: To study the influence of psychological nursing intervention on psychological status and all-cause mortality in the ICU. Methods: A total of 100 patients at high nutritional risk, receiving nutrition support in the ICU of our hospital from June 2021 to June 2023, were retrospectively included. Based on whether patients received psychological nursing intervention, they were divided into a control group (n = 50, routine care) and a study group (n = 50, routine care plus psychological nursing intervention). The control group received routine care, and the study group received psychological nursing care, along with routine care. Outcome measures included anxiety and depression, assessed using the Self-Rating Anxiety Scale (SAS) and the Self-Rating Depression Scale (SDS); all-cause mortality was compared between the two groups, time to death was collected, and the relationship between psychological status and all-cause mortality was assessed using a Cox proportional hazards regression model. Results: The SDS, SAS scores, and all-cause mortality were significantly lower in the study group than in the control group (P < .05). However, the study group demonstrated greater nursing satisfaction than the control group (P < .05). Psychological status and all-cause mortality were significantly related in univariate analysis. Conclusion: Psychological nursing intervention can effectively reduce the incidence of anxiety and depression in ICU patients at nutritional risk, improve the psychological state of patients, reduce all-cause mortality, and improve the prognosis of patients.
