Observational study of the implementation of medical emergency team in hospital / 中华危重病急救医学

ABSTRACT

Objective:To analyze the implementation of medical emergency team (MET) in Fuxing Hospital of Capital Medical University, and to investigate the characteristics such as the time, department, disease, cause of the MET calls, in order to provide a basis for the improvement of MET's implementation.Methods:A retrospective study was conducted. MET calls that received between January 1st, 2015 and December 31st, 2018 at Fuxing Hospital were collected. The calls' information included the quarter, time, and the patients' gender, age, admission time, department, admission diagnosis, the reason for the calls, the operation and outcome of the MET upon arrival.Results:A total of 846 MET calls were occurred during 4 years from 2015 to 2018. The frequencies of the first and third quarter were relatively high with 28.0% (237/846) and 26.5% (224/846), respectively. The events mainly occurred during the day (0800-1959) with 611 calls (72.2%). There were more men [64.3% (544/846)] than women [35.7% (302/846)]. The calls were mainly from the elderly over 60 years old, and gradually increased with age, which distributed the most in patients aging 80-89 years old, accounting for 51.5% of all calls (436/846). Among all the MET events, 80.5% (681/846) were from department of internal medicine, 18.8% (159/846) were from department of surgery, and 0.7% (6/846) were from department of gynecology and obstetrics. The top 3 diseases reported in the calls were respiratory diseases [31.6% (267/846)], nervous system diseases [20.8% (176/846)] and circulatory diseases [9.9% (84/846)]. The reason of MET calls showed that abnormal pulse oxygen saturation [SpO 2, 27.8% (235/846)] were the most among 4 vital signs. After MET rescue, 7.3% (62/846) of the patients died, 48.7% (412/846) were transferred to intensive care unit (ICU) for further treatment, and 41.9% (354/846) remained under observation. Conclusions:The frequency of MET calls in Fuxing Hospital of Capital Medical University was relatively stable over the years, mostly received in the daytime (0800-1959) of the first and third quarter. Most of the patients were male aged 80-89 years old. The most MET calls were from department of internal medicine and due to respiratory disease. SpO 2 was the most common abnormal indicator. According to the above characteristics, MET can focus on them in the future.
