A retrospective analysis was conducted on the clinical data of 5 elderly patients with delirium admitted to the EICU, who suffered from acute respiratory distress syndrome (ARDS), severe acute pancreatitis, severe sepsis, chronic renal failure and severe craniocerebral injury respectively. The CAM-ICU scale was used as the main outcome criterion for delirium assessment, and the FAM-CAM scale was applied to assist in rapid screening and dynamic monitoring. Targeted nursing interventions were implemented in combination with the pathological characteristics of each disease, and the nursing effects and experience were summarized. After standardized nursing interventions, all 5 patients met the delirium remission criteria evaluated by the CAM-ICU scale, were transferred to the general ward after their conditions stabilized, and no adverse events such as falls, pressure ulcers and unplanned extubation caused by delirium occurred. For elderly EICU patients with delirium complicating different diseases, the combined assessment model of "CAM-ICU as the main method and FAM-CAM as the supplement" for early identification and dynamic monitoring, combined with individualized nursing interventions based on disease characteristics, can effectively improve delirium symptoms, reduce the incidence of adverse events and enhance the quality of nursing.
