Abstract: Objective: To optimize the intra-hospital transportation process of critical patients in ICU, reduce the incidence of adverse events and improve the safety. Methods: Before the optimization of the process, the patients were evaluated and items were prepared according to the experience of doctors and nurses. Application" the ICU transferc decision checklist", the first part is the risk assessment of critical patients. The second part is the self-designed pre-transfer checklist, which mainly includes patient preparation, goods preparation, personnel preparation, relevant department confirmation and medical observation record sheet. Results: Before the optimization of the process, six adverse events occurred before the transportation decision-making checklists. The incidence was 15.0%, including 2 cases of condition changing events, 1 case of falls, 1 case of instrument and equipment failure, 1 cases of insufficient oxygen supply in the oxygen bottle and 1 cases of insufficient power of the micro pump. The rate of transferring with complete first-aid kits achieved 93.0%. After the optimization, 3 cases of adverse events occurred during intra-hospital transportation of critically ill patients, whose incidence was 6.7%, including 1 cases of condition changing events, 1 cases of instrument failure and 1 cases of insufficient oxygen supply in the oxygen bottle. The rate of transferring with complete first-aid kits achieved 98.0%. Conclusion: Optimization the intra-hospital transportation process of critically ill patients can help reduce the incidence of adverse events and improve safety of critically ill patients.
