OBJECTIVE: This study was designed to verify the effect of group random quality control on the first aid ability of ward doctors and nurses with regard to the resuscitation of patients with in-hospital cardiac arrest (IHCA). METHODS: The first aid quality control team of our hospital was established in December 2018, when the number, qualifications, organizational structure, quality control methods, and responsibilities of the team and team members were determined. The baseline data and assessment results of examinees, the rates of return of spontaneous circulation (ROSC), and the discharge survival rate of IHCA patients in 2019 and 2020 were compared. RESULTS: There were no significant differences in the baseline data of examinees at each stage (p > 0.05). As time went on, the results of the four practical examinations were significantly improved (pairwise comparison, p < 0.05). The number of problems in examinations was significantly higher for physicians than for nurses. After guidance in department relearning, the incidence of related problems was significantly reduced, but the mastery of the frequency and depth of extracorporeal cardiac compression were not always up to standard. The proportion of critically ill patients and the incidence of IHCA in the hospital in 2020 was higher than in 2019 (p < 0.05), and the ROSC rate was also significantly higher than it was in 2019 (p < 0.05), but the difference in the survival rate at discharge was not statistically significant (p > 0.05). CONCLUSION: Group random quality control meets the needs of IHCA emergencies, and it can improve the first aid skills and organizational coordination of doctors and nurses on the ward through continuous discovery and problem solving so that the ultimate goal of improving the success rate of resuscitation can be achieved.

With the development of China's medical technology and the emergence of an aging society, the number of hospitalized patients is higher, the age of patients is older, and the range and number of underlying diseases is greater. This means the general condition of patients has become complex and critical, and in-hospital cardiac arrest (IHCA) is inevitable. It is reported that there are about 200,000 IHCA patients in the United States every year. 1 At present, extracorporeal cardiopulmonary resuscitation (ECPR) remains an economic and effective intervention for patients with IHCA. 2 The common causes of cardiac arrest include hypovolemia, hypoxia, hypokalemia, hyperkalemia, hypothermia, acute myocardium infarction, tension pneumothorax, tamponade cardiac, toxicosis, and thromboembolism. In China, where citizens' awareness of safeguarding their rights has increased significantly, if the medical staff neglect or do not follow standardized first aid procedures, this will not only affect the quality of the first aid, but also cause doctor-patient disputes. Therefore, it is of great importance to improve the emergency response ability, operation standardization, and organization coordination of medical staff on hospital wards. Quality control inspection is an important means of ensuring the continuous improvement of hospital quality as well as promoting reform and improving the skills of hospital staff. Before 2019, the quality control of first aid carried out by doctors and nurses in the hospital was implemented separately, and standardized first aid skills team training and assessment was focused on the nursing staff 3 . Due to the advance planning arrangement of each department, it has the characteristics of sufficient nurses' manpower arrangement, highly performative, lack of physicians' participation, and extremely incompatible with the clinical emergency status. At this time, the medical department merely issued cardiopulmonary resuscitation (CPR) guidelines to doctors for self-study, but arranged no tracking of their acquired skills. Some studies have found that the use of unannounced on-site simulation exercises is conducive to greater improvement of staff learning and is more effective than off-site training. 4 Since 2019, the hospital has implemented group random quality control of on-site medical care. With the continuous involvement of all medical staff and the guidance of a quality control team, by the end of 2020, not only had the first aid ability of the medical and nursing teams in the hospital significantly improved, but also the resuscitation success rate had improved. This paper examines how this was achieved in more detail. Our hypotheses were: (1) Randomized group quality control may improve the emergency operational efficiency of the hospital;

(2) Randomized group quality control model may improve the outcome of patients with cardiac arrest in the hospital.

The Establishment of the First Aid Quality Control Team

In December 2018, the first aid quality control team was established and jointly led by the medical department and the nursing department. The team was composed of four doctors (two in the emergency department and two in the intensive care department), eight head nurses, and four emergency specialist nurses. All the team members participated in providing basic life support (BLS) and advanced cardiac life support training in Jiangsu Gulou Hospital training base, validated by the American Heart Association (AHA), and the team member all passed the examination. The leadership of the team was assumed by the most senior doctor, who was responsible for organizing and coordinating the personnel and for arranging the time of each quality control event. The quality control team for the clinical examination had to include the following five people: a doctor, the team leader, who was responsible for overseeing medical records before the examination, and checking the standardization of respiratory management and medical orders in quality control; three head nurses, one who was responsible for checking the quality of venous access management, compression, and defibrillation, one who was responsible for the quality of support for other organ functions, and a third one, who was responsible for checking the quality of the management of the ward and external coordination; and an emergency specialist nurse, who was responsible for preparing and transporting the simulation patient to the clinical sites and for quality control of summary patient records and patient data system input.

At the beginning of 2019, a total of 47 wards in the hospital participated in the assessment of first aid quality control. The departments involved in this study were as follows: Internal medicine wards (ie respiratory, gastroenterology, rheumatism, endocrinology, cardiology, hematology, oncology, radiotherapy, traditional Chinese medicine, rehabilitation, etc.), Surgery departments (ie orthopedics, cardiac surgery, thoracic surgery, gastrointestinal surgery, breast surgery, burn surgery, brain surgery, etc.), obstetrics and gynecology, pediatrics (except newborns), operating room, gastroscopy room, intensive care unit, and inpatients (except operating room and gastroscopy room). The assessment results of new departments after that date were not included in the study. Each department was assessed every six months, and the assessment results were linked to the performance of the department. Patients were selected according to the characteristics of each department. The symptoms, signs, and progression of the patients were set out according to the ten most common reversible causes of cardiac arrest. The quality control team went to the ward to be examined without prior notice and selected an empty bed or public area for a simulation drill. After being alerted, the medical staff on duty had to immediately act as if they were in a real emergency situation. Members of the quality control team checked their performance according to their respective division of labor and the quality assessment form. During the process, only the team leader gave situational prompts, and the emergency specialist nurse was responsible for simulating the patient symptom description, and other quality control members did not speak. After the practical assessment, the quality control team summarized the assessment problems first, and then gave feedback to the doctor and nurse representative. The quality control problems concerning the emergency response skills of the whole hospital were summarized and fed back to medical and nursing staff once a quarter, and any common problems were rectified in a centralized manner.

Quality inspection items included BLS exploration, the startup of the emergency rescue team, the organization and coordination of the rescue team leader, airway opening, oxygen therapy, cardiac compression, defibrillation, venous access management, drug use, attention to other organs, nursing records, inspection and result tracking, transportation, and rescue discussion. Because there are only a few night shift medical staff on an ordinary ward, during the night shift the rapid response team (RRT) assist with cardiac compression, endotracheal intubation, and defibrillation, but, during the day shift, when assistance is needed, the anesthesiology department is informed and completes endotracheal intubation by telephone, and the defibrillator and ventilator used are from the same department or borrowed from the instrument and equipment center. The emergency and critical departments carry out all the necessary measures themselves.

The research indicators consisted of the following: (1) basic information about the examinees; (2) the quality control results of 47 departments on four occasions; (3) the ranking of problems found in the four major quality control inspections; (4) the proportion of seriously ill and critically ill patients in the hospital; (5) the proportion of CPR patients in inpatients; (6) the percentage of return of spontaneous circulation (ROSC), which refers to the proportion of patients in whom a spontaneous heart rhythm is restored and maintained for more than 20 minutes after CPR out of the total number of patients undergoing CPR; and (7) the discharge survival rate, which refers to the proportion of patients with ROSC still alive at discharge out of the total number of CPR patients.

The basic information about the medical staff was filled in directly after the on-site assessment. The examination questions and scores were exported from the nursing management system (Shanghai KingYee Technology Co., Ltd.) to generate Excel tables. The quality control items of the system included the level I and level II indicators of the quality control inspection formulated by the hospital emergency quality control team according to the guidelines of the AHA for cardiopulmonary resuscitation, the consensus of Chinese cardiopulmonary resuscitation experts, and the consensus of Chinese cardiopulmonary resuscitation training experts, 5,6 and these items were weighted. These items were imported into the information system by engineers, and at a later stage, the contents were fine-tuned according to the guide update at the time. The examiners checked each item one by one according to the assessment form, and the scores of non-standard items were subtracted, and the total score was generated automatically.

For inpatient data collection, the following data and information was obtained from the information section: (1) the total number of inpatients in 2019 and 2020; (2) the number of seriously ill and critically ill patients; (3) the medical record number, name, admission, discharge time and any other basic information of the patient along with the temporary doctor's order including "cardiopulmonary resuscitation" or "cardiac defibrillation." Then, the rescue records of patients who had undergone cardiopulmonary resuscitation and cardiac defibrillation were checked using the hospital information management system (HIS) medical record system (Wuhan Feibo Technology Co., Ltd.) to find out about the resuscitation effect. For patients with a successful resuscitation, their 28-day survival was monitored through their medical history or telephone contact. The following cases were excluded: (1) patients with neonatal asphyxia, (2) patients whose family members were unwilling for them to be resuscitated, (3) patients with pacemakers, and (4) patients with extracorporeal membrane oxygenation. For patients with multiple resuscitations, the resuscitation effect was calculated from the first time. 

The data were statistically analyzed using statistical software SPSS 19.0. Measurement data first underwent a test of normality, then normally distributed measurement data were expressed as mean ± standard deviation (`x ± SD) and evaluated using a t-test or analysis of variance, while non-normally distributed measurement data were expressed as the median and quartile and evaluated using a rank sum test. Count data were expressed as a percentage (%) or thousandth (‰), and compared using a Chi-square test. The value of α was set as 0.05.

1. There were no significant differences in the age, gender, member proportion, professional title, shift, and other basic information related to the medical staff participating in the assessment in each department at the four stages (p > 0.05, Table 1 ). 2. The main problems found during the four quality controls are listed in Table 2 . A total of 24 major problems (including those which were duplicated) were recorded, among which the most common were doctor problems (11, 45 .83%), followed by doctor and nurse problems (9, 37.50%), and then nurse problems (4, 16.67%). The problems could obviously be rectified after the quality control, and the frequency of the same problems decreased significantly, but the mastery of the frequency and depth of extracorporeal cardiac compression was never up to standard (Table 2) Overall, the results of the four stages showed an increase each time, there was significant difference in the results between each stage (p < 0.05, Table 3 ). 4. There was no statistically significant difference in the proportion of seriously ill in-hospital patients in the hospital between 2020 and 2019 (p > 0.05). However, the proportion of critically ill patients (p < 0.05) and the proportion of patients with IHCA (p < 0.05) in 2020 were higher than in 2019, and the 

ROSC rate was also significantly higher in 2020 than in 2019 (p < 0.05), but there was no significant difference in the discharge survival rate of patients after resuscitation (p > 0.05, Table 4 ).

The Random Quality Control Method, IHCA Emergency State, and Inspection Efficiency IHCA can be divided into two types: precursory and unexpected. For precursory IHCA, it is possible to make full preparations in terms of manpower, materials, treatment plan, and family communication in advance, to ensure the quality of rescue, and to improve the psychological preparation of family members, and it can be dealt with in the general emergency room and intensive care unit. In contrast, unexpected IHCA can result in problems such as insufficient manpower, materials not in the best state of preparation, poor coordination between doctors and nurses, and insufficient communication between family members because it happens suddenly, making the first aid busy and chaotic, which not only affects the quality of the treatment, but also increases the possibility of doctor-patient conflicts. This kind of situation can easily occur on an ordinary ward. 7 One study concluded 

that, after general first aid training, the first aid knowledge and skills of medical staff can be significantly improved, but its effect on clinical practice is not clear because it is divorced from clinical practice. 8 Random quality control inspection is especially suitable for the emergency state of unexpected IHCA, because through the scene drill, it is not only possible to exercise the emergency handling ability of medical staff, but it also means that the problems in the rescue can be identified and guidelines established for future emergencies. This research project was carried out under the joint leadership of the medical department and the nursing department and was closely related to the assessment of both departments and individuals. Therefore, the medical staff of all the departments attached great importance to it and took quality control inspection seriously and actively rectified any quality control problems. In-hospital CPR is a team emergency exercise with multiple participants, and many key links will be involved at the same time. Quality control is required, and the group quality control method used in this study can not only ensure that each inspector has a focus on quality control, but also ensure that each link has the inspector's attention. In addition, the quality control team leaders are very careful about the setting of the quality control cases in each department, and they consider the characteristics of the special diseases in various departments, combined with common complications and severe disease, to make the case closer to the characteristics of the specialty. Therefore, the group random quality control method is as close as possible to the IHCA emergency state and makes up for the many shortcomings of previous quality control methods by improving the efficiency of the practice of quality control.

In this study, with the passage of time, the ward assessment results improved significantly, suggesting that group random quality control can significantly improve the first aid skills of medical staff. In addition, "tacit cooperation" is particularly important to improving the operational efficiency of a team. Fang et al 9 confirmed that through the establishment of a practical first aid team of both doctors and nurses, the arrival time of rescue workers was significantly shortened, and the time points of cardiac compression, and the use of a simple breathing balloon, adrenaline, and defibrillation were significantly advanced. In the process of exercise learning, if the actual ability of the participants and the progress of the patient's condition are not taken into consideration, only simple exercises are carried out based on a script, and it is easy to have an unpredictable experience as in the rescue process of actual cases. 10 In the period 2015-2019, during the assessment of a planned first aid drill of the nursing team in the hospital, if sudden situations were added to the exercise, ward nurses would often be at a loss as to what to do. Although in 2019 the medical staff on the wards in this study also found it difficult to adapt to an emergency, as they gained more experience, by 2020 the response ability of the medical staff was significantly improved. This is probably due to the participation of doctors in the rescue drill, as well as the improvement of the team leader's awareness and first aid skills. Focusing on the specific problems of the four quality controls stages, it was found that some medical problems could be significantly improved, but the mastery of the frequency and depth of extracorporeal cardiac compression were always not up to standard. One study 11 revealed that if the quality of the CPR is poor for even the first four minutes, it will significantly affect the hemodynamics and survival outcomes. Therefore, improving the quality of compression is related to the overall success of the resuscitation. Another foreign study 12 found that in the actual rescue process, 28.1% of the trained medical staff failed to reach the standard of compression frequency, and 37.4% of the trained medical 4558 staff failed to reach the standard of compression depth. A survey on the quality of cardiac compressions of emergency workers in one hospital in China found that only approximately 50% of them met the standard. 13 A recent foreign study 14 showed that in the process of rescue, only 37% of cardiac compression frequency and 63.9% of cardiac compression depth reached the standard. Therefore, there is a long way to go for medical staff on the wards to improve the quality of cardiac compression. 15 Group Random Quality Control and the ROSC Rate of IHCA

In 2020, as a result of the COVID-19 pandemic, the total number of patients in the hospital was less than that in 2019, but the proportion of critically ill patients was significantly higher (8.91% vs 8.31%, p < 0.05). The incidence of IHCA was also significantly higher in 2020 than in 2019 (p < 0.05) and slightly higher than that reported in the UK (1.6 ‰), 16 19 The reason may be that in view of the medical conditions and treatment levels of hospitals in various countries, there will be significant differences in the survival rate of in-hospital resuscitation between hospitals. 23 With regard to this study, the objectives, schemes, and assessment tools of hospital first aid quality assessment before this study were completely different from those after 2019, but the historical control design could not be assessed any longer, so it was only possible to compare the results of the immature implementation (2019) and mature implementation (2020) of the group random quality control scheme. Moreover, because of the short study period, the number of cases was relatively small, and so the results of the comparison may not be accurate. A multi-center large sample randomized controlled study should be carried out. Additionally, the indicators of neurological status of these patients were not analyzed due to incomplete clinical data. Future studies including these indicators are needed to validate the current findings.

Group random quality control is a continuous quality improvement method involving both doctors and nurses. The implementation plan conforms to the emergency state of IHCA, and it can also improve the first aid skills and organizational coordination of doctors and nurses on the ward through continuous discovery and rectification of problems as they occur, with a view to ultimately improving the success rate of resuscitation. Therefore, group random quality control is worthy of clinical reference and more widespread use.
