Acute stress disorder is a serious hazard in elderly patients. This disorder can cause physical and psychological discomfort, affecting the patient’s life quality of functioning. Psychological intervention can help patients relieve anxiety and fear, and improve patients’ acceptance and participation in emergency nursing.

Optimization of community emergency care processes can provide faster, more efficient, professional care services through process optimization. If the two are combined, its efficacy can be further improved. Therefore, this study further explored the therapeutic effect of combining the two.

Elderly patients diagnosed with ASD were selected as samples from the community. The intervention group adopted the optimized community emergency nursing process combined with psychological intervention, and the control group adopted the standard nursing. The Stanford Acute Stress Response Questionnaire (SASRQ) and 3-minute Disorder Assessment Scale (3D-CAM) were used to measure stress levels and cognitive dysfunction, respectively. SPSS23.0 was used for statistical analysis.

ASD symptoms were significantly reduced in the intervention group compared with the control group (P≤0.05). SASRQ scores decreased by 35 percent, indicating decreased levels of acute stress. The 3D-CAM score showed a 25% improvement in cognitive function in the intervention group.

Optimizing the community emergency nursing process combined with psychological intervention is an effective way to treat acute stress disorder in the elderly. This integrated care model contributes to improved mental health outcomes and should be considered in clinical practice.
