Objective To explore the effect of critical value disposal after the human customer service participated in the outpatient critical value closed-loop management.Methods Patients with outpatient critical value in a hospital from January to June 2022 and from January to June 2023 were selected as the research objects,and the treatment rate and satisfaction of patients with in critical value 2 h,2 h to 6 h and more than 6 h before and after the participation of hu-man customer service were statistically analyzed.Results After the human customer service participated in the closed-loop management of outpatient critical value,the critical value disposal rate of patients in the observation group was significantly higher than that in the control group within 2 h to 6 h,and the patient satisfaction was higher than that in the control group,the difference was statistically significant(P<0.05).The treatment rate of critical value within 2 h and more than 6 h in the observation group was lower than that in the control group,and the difference was not statisti-cally significant(P>0.05).Conclusion The use of human customer service to participate in the closed-loop man-agement of outpatient critical value through continuous intervention improves the efficiency of outpatient critical value disposal and patient satisfaction,and guarantees the life safety of patients.
