Objective To construct a first-aid and emergency dual channel management scheme，and to explore its application effects on the treatment of emergency patients treated by ambulance. Methods A team was established to construct a first-aid and emergency dual-channel management scheme，optimize the layout of emergency department entrance channels，improve the medical treatment process for patients treated by ambulance，implement zoning treatment and rapid triage for critically ill patients in the resuscitation unit. From October to December of 2023，patients admitted to the emergency room were selected as the experimental group，and patients from another hospital campus in the same period were selected as the control group. The experimental group adopted a dual-channel management scheme，and the control group implemented a conventional protocol. The differences in triage time，examination time，definitive treatment time，and green channel stay time of patients in the "three major centers” were compared between the two groups. Results 132 patients in the experimental group and 122 patients in the control group were included. After the implementation of dual-channel management scheme，the time of patient triage was shortened from 3.6（2.0，4.0） min to 2.1（2.0，3.0） min（P<0.001），the time for examination was shortened from 58.7（29.0，73.0） min to 33.4（10.0，43.0） min（P<0.001），and the time to definitive treatment was shortened from 76.6（31.0，98.0） min to 45.6（11.0，57.0） min（P<0.001）. The stay time of the green channel for patients in the “three major centers” was shortened from 56.7（41.0，75.0） min to 31.0（17.0，41.0） min （P<0.05）. Conclusion The application of the first-aid and emergency dual channel management can reduce the triage time of patients transported by ambulance，shorten the examination time，treatment time and the green channel stay time for patients in the “three major centers”，thereby improving the treatment efficiency.
