Abstract: Objective To explore the influencing factors and countermeasures of delayed rapid response team （RRT）activation in the Department of Neurosurgery. Methods We retrospectively analyzed the data of hospitalized patients treated with RRT from the Department of Neurosurgery in a tertiary class A hospital in Hangzhou,Zhejiang Province from January 2019 to June 2022. The patients were divided into two groups（delayed and non-delayed）according to whether the call duration was longer than 15 minutes. We compared the differences in clinical indicators between the two groups and analyzed influencing factors of delayed RRT activation. Results A total of 86 patients（59.3%）were found to experience delayed RRT activation among 145 included patients. Logistic regres-sion analysis showed that aged 65 and over,having more than two comorbidities,a score of GCS less than 9,and night duty（17:01—07:59）were independent risk factors for delayed RRT activation（P<0.05）. A score of MEWS（Modified Early Warning Score）more than 7 was an independent protective factor（P<0.05）. Conclusion Nurses should pay attention to aged or critically ill patients,patients with multiple comorbidities or nursed during night duty and ensure the continuity of care. It is suggested to establish a specialized early warning system for neurosurgery patients. The hospitals should strengthen monitoring and data analysis and provide training for nurses through diversified ways to help them summon the rapid response system effectively.
