Monitoring cardiopulmonary resuscitation quality in emergency departments: a national survey in China on current knowledge, attitudes, and practices

Abstract

Background

To investigate current knowledge, attitudes, and practices for CPR quality control among emergency physicians in Chinese tertiary hospitals.

Methods

Anonymous questionnaires were distributed to physicians in 75 tertiary hospitals in China between January and July 2018.

Results

A total of 1405 respondents answered the survey without obvious logical errors. Only 54.4% respondents knew all criteria of high-quality CPR. A total of 91.0% of respondents considered CPR quality monitoring should be used, 72.4% knew the objective method for monitoring, and 63.2% always/often monitored CPR quality during actual resuscitation. The main problems during CPR were related to chest compression: low quality due to fatigue (67.3%), inappropriate depth (57.3%) and rate (54.1%). The use of recommended monitoring methods was reported as follows, ETCO2 was 42.7%, audio-visual feedback devices was 10.1%, coronary perfusion pressure was 17.9%, and invasive arterial pressure was 31.1%. A total of 96.3% of respondents considered it necessary to participate in regular CPR retraining, but 21.4% did not receive any retraining. The ideal retraining interval was considered to be 3 to 6 months, but the actual interval was 6 to 12 months. Only 49.7% of respondents reported that feedback devices were always/often used in CPR training.

Conclusion

Chinese emergency physicians were very concerned about CPR quality, but they did not fully understand the high-quality criteria and their impact on prognosis. CPR quality monitoring was not a routine procedure during actual resuscitation. The methods recommended in guidelines were rarely used in practice. Many physicians had not received retraining or received retraining at long intervals. Feedback devices were not commonly used in CPR training.

Peer Review reports

Background

The outcomes of Chinese cardiac arrest patients were very poor. In Beijing, the capital of China and where medical technology was well developed, only 1.3% of out-of-hospital cardiac arrest (OHCA) patients were discharged alive, and 1.0% had a favorable neurological outcome (defined as cerebral performance category score of 1 or 2) in 2012 [1]. In 2014, 9.1% of in-hospital cardiac arrest (IHCA) patients were discharged alive and 6.4% had a favourable neurological outcome [2]. The survival and neurological outcomes of OHCA in Beijing did not improve significantly from 2013 to 2017 [3]. The outcomes reported in other cities in China were similar [4,5,6].

Many factors contributed to these results in China. The current CPR training rate among Chinese residents was less than 1% [7]. Bystander CPR was underutilized, with implementation rates of only 11.4% in Beijing and 4.2% in Shanghai, which were much lower than those in other developed countries [7]. EMS operating mechanism in Chinese city was different. Several cities have implemented dispatcher-assisted CPR, while others would not [8]. The median interval from call receipt to ambulance arrival at the collapse location was usually more than 15 min [3,4,5,6]. The number of AEDs per 100,000 residents was lower than that in many developed countries (17.5, 13, and 5 in the developed Chinese cities of Shenzhen, Haikou, and Shanghai, respectively) [9]. Target temperature management for cardiac arrest patients was still in the early stage, and only 7.8% of physicians and 5.7% of nurses had implemented therapeutic hypothermia for cardiac arrest patients [10]. Nevertheless, Chinese emergency physicians have been working hard to improve the prognosis of cardiac arrest patients.

CPR was a lifesaving intervention and the cornerstone of resuscitation. When cardiac arrest took place, blood circulation was completely stopped. CPR could provide 10% to 30% of normal blood flow to the heart and 30% to 40% of normal blood flow to the brain [11]. Early CPR was an important link in the survival chain, regardless of OHCA or IHCA cases [12].

Survival from cardiac arrest depended on early recognition of the arrest event and immediate activation of the emergency response system, but equally critical was that CPR delivered was high-quality. High-quality CPR included ensuring an adequate chest compression rate and depth, allowing full chest recoil between compressions, minimizing interruptions in chest compressions, and avoiding excessive ventilation [13]. There was clear evidence that providing high-quality CPR significantly improves resuscitation outcomes [14,15,16,17].

Poor-quality CPR should be considered preventable harm. Monitoring both patient physiologic parameters and provider performance during CPR was essential to optimizing CPR quality [13]. Visual observation was the most basic monitoring method. In 2013, the American Heart Association (AHA) published a consensus statement focused on strategies to improve CPR quality [17]. Patient physiologic parameters during CPR that were considered pertinent for monitoring included invasive hemodynamic data (coronary perfusion pressure > 20 mmHg or arterial diastolic pressure > 25 mmHg) and end-tidal carbon dioxide (ETCO2) concentrations > 20 mmHg [17]. Audiovisual feedback devices to measure provider CPR performance were widely accepted [17]. CPR guidelines recommended using feedback devices for real-time optimization of CPR performance [13, 18].

Today, few healthcare organizations consistently applied strategies of systematically monitoring CPR quality even though there was an unacceptable disparity in the quality of resuscitation care and outcomes [13, 18]. As the current knowledge, attitudes, and practices for CPR quality monitoring in China have never been reported, the aim of the present survey was to investigate the awareness and application of CPR quality monitoring among Chinese emergency physicians.

Methods

Geographical background

Mainland China was divided into six administrative regions according to geographical distribution, including the eastern region, northern region, northeastern region, southwestern region, southcentral region, and northwestern region. These regions differed in medical development [19].

Study design

This was a cross-sectional multicenter study. In China, only tertiary, or Level III, hospitals had independent emergency departments and were also teaching hospitals, so these hospitals were identified in an attempt to target providers most likely to care for cardiac arrest patients. Tertiary general hospitals in mainland China were selected by separate random sampling in the six administrative regions. We screened for all 374 tertiary general hospitals, which were then coded randomly by SPSS version 25.0 (IBMCorp, Armonk, New York, USA) and then arranged in ascending order in each administrative region. The top 20% of hospitals were enrolled in the study, with alternative hospitals considered (in ascending order) if any enrolled hospitals were inaccessible or refused to participate. Finally, 75 hospitals were included. We then conducted a questionnaire survey for all emergency physicians of the selected hospitals.

The questionnaire was developed by a senior emergency physician, and examined and discussed three times by an expert team consisting of an epidemiologist and emergency specialists experienced in the management of cardiac arrest patients. The questionnaire included three parts: (1) background data of the respondent; (2) the respondent’s awareness and practices for quality monitoring during actual CPR; and (3) awareness and practices for quality monitoring in CPR training. A total of 30 questions were included in the questionnaire, including 3 blank questions, 20 single choice questions and 7 multiple choice questions.The paper questionnaires were distributed to the directors of emergency departments by mail from January to March 2018. Data collection ended in July 2018.

The study protocol was approved by Peking University Third Hospital Medical Science Research Ethics Committee (Project number: IRB00006761-M2018030, Ethics approval document number: 2018–176-01).

Statistical methods

The data were analysed by SPSS version 25.0 (IBMCorp, Armonk, New York, USA). Quantitative variables were expressed as the mean (standard deviation) when following a Gaussian distribution, or median (interquartile range 25%-75%) otherwise. Qualitative variables were expressed as frequencies.

Results

A total of 1489 (93.1%) responses were collected from 1600 questionnaires in 75 hospitals; 1405 responses were analysed and 84 were excluded because of obvious logical errors. The general characteristics of the respondents were described in Table 1.

Table 1 Characteristics of respondents

Knowledge and attitude for high-quality CPR and quality monitoring

Only 54.4% respondents knew all six criteria of high-quality CPR. A total of 60.9% knew all four criteria of high-quality chest compression and 78.2% knew both criteria of avoiding excessive ventilation. A total of 91.0% of respondents considered CPR quality monitoring should be used, and 72.4% knew at least one objective method for CPR quality monitoring. Among the recommended quality monitoring methods, only ETCO2 was well known by 71.7% respondents, while others were not.

The knowledge and attitude for CPR quality and quality monitoring were described in Table 2.

Table 2 Knowledge and attitude for CPR quality and quality monitoring

Practices of CPR quality monitoring

The main problems during CPR were related to chest compression: low quality due to fatigue (67.3%), inappropriate depth (57.3%) and rate (54.1%). A total of 63.2% always and often monitored CPR quality during actual CPR. Methods not recommended by guidelines were usually used for CPR quality monitoring, such as observing ECG waveforms and SpO2 waveforms, and pulse oximetry plethysmographic waveforms. In contrast, the methods recommended by guidelines, such as ETCO2, coronary perfusion pressure, invasive arterial pressure and audiovisual feedback devices, were not widely used.

The practices of CPR quality monitoring during actual resuscitation were described in Table 3.

Table 3 The practices of CPR quality monitoring during actual resuscitation

Among the quality monitoring methods recommended by guidelines, ETCO2 and invasive arterial pressure were used more often than others. The main reason why these methods were not used was that the emergency department did not have the equipment. The use of recommended monitoring technology and reasons for not always using were described in Fig. 1 and Fig. 2.

CPR quality monitoring in training

A total of 96.3% of respondents considered it necessary to participate in regular CPR retraining, but 21.4% did not receive any retraining. The ideal retraining interval was considered to be 3 to 6 months, but the actual interval was 6 to 12 months. Only 49.7% respondents reported they always/often used feedback devices in CPR training. Practices and attitudes on quality monitoring in CPR training were described in Table 4.

Discussion

Knowledge and attitudes for CPR quality monitoring

We found a good situation in which 92.1% of respondents considered CPR quality monitoring to be needed during resuscitation. Mechanical compression devices were designed for some special situations and were considered to reduce the physical burden of emergency physicians [20]. Because emergency departments in China were often crowded, the use of mechanical devices during resuscitation was common. Even in this situation, 94.3% of respondents considered CPR quality to need to be monitored. This showed that emergency physicians were concerned about CPR quality.

High-quality CPR was an important link between survival chains, and it may be more important than other links [12]. Unfortunately, only 54.4% of respondents in this survey knew all six criteria of high-quality CPR and 60.9% knew all four criteria of high-quality chest compression. Most respondents were concerned about chest compression depth, rate and chest recoil between compressions. However, it was concluded that emergency physicians in tertiary general hospitals did not pay enough attention to minimizing compression interruptions. Minimizing compression interruption was also an important criterion of high-quality CPR emphasized in guidelines [13, 18]. Continuous chest compressions could maintain adequate coronary perfusion pressure, and increase the likelihood of ROSC [21]. Chest compression fraction over 80% was recommended to ensure that compressions were continued with as few interruptions as possible during CPR. However, in this survey, only 68.0% of respondents knew this criterion. This may become a problem for improving CPR quality and it was important to strengthen the education of emergency phycisians to minimize compression interruption.

Visual observation was the most basic and widely used monitoring method, but objective parameters were recommended for accurate monitoring [17]. We found that 72.4% of respondents knew objective monitoring methods. Clinical guidelines and academic conferences were the main ways emergency phycisians learned about their technology. However, in this survey, Chinese emergency physicians did not know some recommended techniques, especially audiovisual feedback devices.

It was important to find that many respondents had some misunderstandings about CPR quality control. For example, 71.3% of Chinese emergency physicians considered that using CPR quality monitoring devices could improve cardiac arrest patients’ outcomes. While current studies have not demonstrated significant improvement in outcomes related to CPR quality monitoring during resuscitation [13, 17, 22].

Although Chinese emergency physicians were concerned about CPR quality, they lacked an understanding of high-quality CPR criteria, new objective monitoring methods and research results.

Practices of CPR quality monitoring

Chest compression quality was a main problem during actual resuscitation in China. Low quality due to fatigue, inappropriate compression depth, and inappropriate compression rate were the top three problems reported by respondents. In contrast, personal ability and team cooperation were not issues. Because of this, quality control should be placed on a vital position in China. However, CPR quality monitoring was not a routine procedure in Chinese emergency department. Only 63.2% of respondents reported that they always/often monitored CPR quality during actual resuscitation. This showed that Chinese emergency physicians did not comply with the guidelines for CPR quality monitoring.

Accurate measurement of CPR quality was a precondition for high quality CPR. Objective parameters were better than visual observation [13]. Our results showed that recommended methods were rarely used in Chinese emergency departments. ETCO2 was the most widely used among these methods. The opinions and clinical experience of experts strongly supported using ETCO2 to optimize chest compression quality during resuscitation [13, 17]. Endotracheal intubation was not difficult for Chinese emergency physicians, because they had rich clinical experience and visualization devices were widely used. Previous studies showed that advanced airway could be placed in the first few minutes during resuscitation in Chinese emergency departments [23]. In this situation, ETCO2 data was easier to obtain. This could explain why ETCO2 was widely used in China. However, Using an audio-visual feedback device to monitor CPR quality was another recommended method by guidelines [13, 18]. It was a noninvasive technology for real-time monitoring, recording, and feedback about CPR performance [24, 25]. We found that less than 20% of respondents had used this equipment. Pulse oximetry was widely used, and its waveform could reflect peripheral tissue perfusion. Some research found that the appearance of pulse oximetry plethysmographic waveforms was related to CPR quality [26, 27]. Pulse oximetry plethysmographic waveforms, as a monitoring technology, were recommended for CPR quality monitoring by Chinese expert consensus in 2018. However, its usage rate was still lower than that of ETCO2 and invasive arterial pressure. The survey reported that few emergency departments had such equipment, and many emergency physicians did not know this technology.

Unrecommended methods were widely used for quality monitoring in Chinese emergency department and was the biggest problem. Palpation of the arterial pulse, observation of the ECG waveform, and observation of the SpO2 waveform were the top three most widely used methods. Palpation of arterial pulse was the most widely used method to evaluate chest compression quality, but it has been shown to be unreliable and cannot be used for continuous monitoring during actual resuscitation [28, 29]. Therefore, the guidelines did not recommend this method for CPR quality monitoring [17]. Regular ECG waveforms accompanying chest compression can be observed in some patients, but the shape of the waveform had no clear relationship with the quality of chest compressions [30]. The ECG waveform was widely used for quality monitoring, reflecting the misunderstanding of its meaning in Chinese emergency physicians.

Continuing education for emergency physicians was crucial to increase the use of recommended methods [31]. Although CPR quality monitoring had been recommended by CPR guidelines, fewer specific consensus protocols existed that provided detail on how to better implement the monitoring. The development and publication of standardized monitoring protocols would likely help physicians better implement CPR quality monitoring in China.

CPR quality monitoring in training

Basic life support and advanced cardiac life support techniques were the core skills of resuscitation [32]. The CPR training course was a key part of Chinese resident standardized training program. In most tertiary hospitals, all emergency physicians needed to attend basic life support courses and many of them also needed to attend advanced cardiac life support courses. CPR training courses in many hospitals were certified by the American Heart Association [33].

CPR training was not a one-time training. Retraining was recommended by AHA guidelines, because skills and knowledge may decay within 3 to 12 months after initial training [32]. The concept of retraining was widely accepted in China, where 96.3% of respondents believed it was necessary to retrain after initial training. Responses showed that CPR retraining received great attention, and that a “frequent” retraining concept was more acceptable. A total of 72.8% of respondents considered the ideal interval between trainings to be 3 to 6 months, although there was no clear recommendation on the optimal time interval [32]. Unfortunately, the survey results revealed a large gap between attitudes and practice, as 21.4% of emergency physicians did not receive any retraining after initial training. Among those who did, the actual retraining interval was 6 to 12 months, significantly longer than desired. This showed that most hospitals did not have standard retraining systems. Retraining may be difficult to implement in some hospitals. Short-term frequent retraining may be a solution in China. Because it would not increase the cost, if the total training time was fixed. Physicians were more likely to take part in a short training course after busy work. And frequent retraining was helpful to consolidate skills.

According to AHA’s CPR guidelines, feedback devices should be used in CPR training [32]. This attitude was supported by 90.1% of respondents, who believed that CPR feedback devices can improve performance during training. However, attitudes and practice was so different. The typical training course in Chinese hospitals includes two parts: theory training and skills training. While the structure of the training course was reasonable, only 49.7% of respondents replied that CPR feedback devices were always/often used in training, and 25.1% replied that they never used feedback devices. In developing countries such as China, there were many hospitals that have no ability to purchase these devices. This may become an important barrier to improving CPR quality.

Conclusions

In this survey we found that Chinese physicians in tertiary hospitals were very concerned about CPR quality, but they did not fully understand the high-quality criteria and their impact on prognosis. Most emergency physicians considered it necessary to monitor CPR quality, but quality monitoring was not a routine procedure during actual resuscitation. Recommended monitoring methods, such as audio-visual feedback devices, were rarely used in practice. However, many physicians used unrecommended methods. Although retraining was considered important, many physicians had not received retraining or received retraining at long intervals. Feedback devices were not widely used in CPR training.

In the future, Chinese emergency physicians should receive systematic continuing education on CPR quality control. A standard operation procedure should be established to guide CPR quality monitoring during actual resuscitation, including hemodynamic parameters, ETCO2 and audio-visual feedback devices. Retraining plans and feedback devices should also be an integral part of CPR training.

Limitations

Emergency departments of tertiary hospitals were targeted for this survey. Physicians in these hospitals were likely to have the most experience caring for cardiac arrest patients. At the same time, these hospitals had the most advanced equipment. The overrepresentation of these hospitals may have subjected the survey to bias. In other words, it was likely that the CPR quality monitoring responses reflected in our survey demonstrated an optimistic perspective. The true proportions of knowledge, attitudes, and practices of monitoring across all Chinese hospitals may be lower than those reported in this survey. Additionally, although the majority of published examples of quantifying qualitative data used dichotomous variables for simplicity, such conversion may result in overestimation or underestimation due to identical grading of responses such as “usually” and “always” and “sometimes” and “never.”
