Abstract: Objective To construct and apply the nursing quality evaluation index system for intrahospital trans-port of critically ill patients，in order to provide standard and quantitative basis for the nursing quality of intrahos-pital transport of critically ill patients. Methods The index system was established based on Delphi method. In addition，the patient risk assessment accuracy rate and readiness qualified rate before transport were used to man-age the transport quality of critical patients in emergency department. Continuous quality improvement was per-formed based on indicator data. Results The final evaluation index system included 3 level indicators，13 secondary indicators，43 tertiary indicators. In July and October 2019，62.4%（241/379） and 91.4%（454/497） of patients re-ceived correct risk assessment，and 71.6%（453/632） and 87.3%（774/881） of patients were qualified for transport.Data extracted from the hospital information system showed that the incidence of adverse events related to transport equipment decreased from 32.12% to 12.79%. Conclusion The nursing quality evaluation index system for intra-hospital transport of critically ill patients is scientific and reasonable，which can be used to evaluate the nursing quality of intrahospital transport in critically ill patients.
