Methods: a total of 100 patients participated in this study. All patients received first aid in the emergency department of our hospital from January 1, 2019. Up to December 31, 2020, patients were divided into two groups with the same number of people in each group, i.e. group A and group B. Patients in Group A received routine medical intervention, while patients in Group B received targeted advanced comprehensive medical intervention. Results: patients in Group B had higher satisfaction with nurses than those in Group A, and the frequency of disputes with nurses was lower than that in Group A. The difference between groups was statistically significant (p<0.05). Conclusion: emergency room patients are a special group. Targeted and advanced comprehensive medical intervention for these patients can reduce the frequency of side effects, avoid secondary injury, reduce patient suffering, improve safety factor and avoid doctor-patient disputes, which is worthy of promotion and recommendation.展开更多
