Evaluation of Public Awareness, Knowledge and Attitudes about Cardiopulmonary Resuscitation: Report of İzmir

Abstract

Objective

Early initiation of cardiopulmonary resuscitation (CPR) by witnesses increases survival after cardiac arrest. In Turkey, our country, it is rare that basic life support (BLS) is initiated by a layperson. In our study, we aimed to use a survey to research awareness, level of knowledge and attitudes of the public to CPR and BLS.

Methods

A 21-question survey was administered to individuals aged ≥18 years on a busy street in a city of a western region of Turkey. Topics such as knowledge about cardiac arrest findings, previous experience of CPR, knowledge of BLS and concerns related to CPR were questioned.

Results

The fully completed forms of 533 people were evaluated. There were 40.7% who stated that they had received training in CPR. For signs of cardiac arrest, 40.7% answered loss of consciousness, 49.3% answered cessation of breathing and 60.7% answered cessation of circulation. It was found that 35.5% could perform only chest compressions, 27.6% could perform mouth-to-mouth ventilation and 28.7% able to perform both. While 52.0% knew the location for performing chest compressions, 34.3% knew the correct depth and 15.6% knew the correct compression–ventilation rate. Bystander CPR was performed by 3.6%.

Conclusion

In conclusion, 40.7% of people living in a highly educated region in the western part of Turkey had received CPR training and 3.6% performed bystander CPR. A majority of participants stated that they were willing to correct and develop their knowledge and skills related to CPR. Effective public CPR training programmes may increase the knowledge and awareness of CPR in the adult population.

Introduction

Sudden cardiac arrest is the main cause of death of millions of people worldwide every year (1). It is possible to save the lives of 50,000 people every year if cardiac massage is properly performed until help arrives. In Europe, 350,000 people lose their lives each year because of out-of-hospital sudden cardiac arrest (OHCA) (2). This number is predicted to be 60,000 in the UK (3). The number of OHCA cases in the US is approximately 300,000, and the mortality rate is 92% (4, 5). The OHCA data in Turkey is insufficient. The survival chance increases two fold if basic life support (BLS) is conducted by the first person to intervene and by the use of automated external defibrillators (AED) (6). Although the significance of cardiopulmonary resuscitation (CPR) is well understood, the rate at which such events are witnessed in many European countries is 37%, and the rate of CPR application to witnessed victims is 44%. Four percent of victims are treated with AED before an emergency team arrives (6, 7).

It has been indicated that CPR that was initiated early by witnesses increased survival after cardiac arrest (810). An important method to increase CPR success for cardiac arrest cases is to increase public knowledge and understanding of the practical applications of CPR. Intervention for a successful result after cardiac arrest is conceptualised as a chain. The chain is no stronger than its weakest link (11). There are many things that can also be done by people who have not received any health education for the first two links in this lifesaving chain. Studies examining the awareness, knowledge levels and attitudes of individuals in Turkey regarding CPR and BLS are limited.

In this study, the awareness, knowledge levels, attitudes and concerns of individuals living in İzmir, which is located in the western region of Turkey, regarding CPR and BLS were investigated using a questionnaire.

Methods

This questionnaire study was initiated after receiving the ethics committee approval (Dokuz Eylül University Medical Faculty Non-invasive Clinical Studies Ethics Committee; protocol no: 1609-GOA, decision no: 2014/24-16). A questionnaire study involving 21 questions regarding cardiac arrest and actions to be taken was conducted; the questionnaire was targeted to reach at least 500 people over 18 years on a densely populated street in Izmir, which is the most developed city in the western region of Turkey.

The demographic features of the participants, their knowledge regarding cardiac arrest signs (cyanosis, difficulty in breathing, nausea, faintness of the skin and other findings), their previous CPR experiences (witnessing cardiac arrest, conducting CPR, having a CPR certificate), whether they know the national phone number for emergency situations, BSL knowledge (compression location, number and rate of ventilation/compression), their concerns regarding CPR (possibility of making a mistake, contracting a contagious disease from blood and vomit, legal concerns) and attitudes (people to whom they will give CPR without hesitation) were among the questions that the participants were asked (Appendix 1).

Correct cardiac arrest findings and algorithms of BLS were determined according to the European Resuscitation Council (ERC) 2010 Resuscitation Guideline (11).

Statistical analysis

The data were analysed with the Statistical Package for the Social Sciences 15.0 software package program (SPSS Inc. Chicago, IL, ABD). The data indicating frequency were displayed as a number (n) and percentage (%); the other data were displayed as mean±standard deviation. The chi-square test was used in the analysis of data indicating frequency. A p value of <0.05 in the examinations was accepted as significant.

Results

Demographic data

533 questionnaire forms that were completely filled out from the 550 questionnaire forms gathered were assessed. The features of the participants are displayed in Table 1.

The demographic features of the participants

CPR training status

The rate of participants who stated that they received CPR training was 40.3%. A majority of these stated that they received training through courses given in their workplace (8.4%). The rate of those who received training during driving schools was 7.3%.

Knowing the signs of cardiac arrest

As cardiac arrest signs, 40.7% of participants responded with loss of consciousness, 49.3% responded with respiratory standstill and 60.7% responded with discontinuation of circulation. Other signs and findings of cardiac arrest included chest pain (38.6%), respiratory distress (31.3%), cyanosis (27.4%), faintness of skin (12.9%) and other (3.8%).

Recognizing cardiac arrest

The rate of knowledge regarding cardiac arrest signs was found to be significantly higher for those who received training than for those who did not receive training (p<0.004). It was observed that only eight people (1.5%) knew three of the cardiac arrest findings in the list and 24 (4.5%) knew two of them (Table 2). The rate of participants who witnessed a cardiac arrest was 18.6%; 2.4% of those who witnessed cardiac arrest performed cardiac compression, 1.5% conducted mouth to mouth ventilation and 3.6% both performed cardiac compression and conducted mouth to mouth ventilation (namely, they applied complete CPR) (Table 3).

CPR knowledge and skills

The rate of participants who knew how to perform cardiac massage in case of sudden cardiac arrest and respiratory standstill was 41.5%; the rate of participants who did not know to perform cardiac massage was 58.5%. Moreover, 35.5% of participants could only perform cardiac compression, 27.6% could only conduct mouth to mouth ventilation and 28.7% could perform both (Table 4). Of all participants, 52% knew the location of cardiac compression, 18.4% knew the rate, 34% knew the correct depth and 15.6% knew the correct ratio of compression/ventilation (Table 5).

CPR attitudes

The rate of the responses provided to the question “To whom do you apply CPR without hesitation?” was 90.6% for a family member, 76.5% for a friend, 95.9% for a neighbour and 42.5% for a stranger.

Concerns regarding CPR

The concerns regarding CPR application included “making a mistake” at a rate of 77.2%, “stopping a working heart” at a rate of 19.3%, “causing harm to organs” at a rate of 11.8%, “causing bone fractures” at a rate of 4.5%, “punishment because of legal reasons” at a rate of 6.3%, “contracting a contagious disease” at a rate of 8.2% and “contamination by blood or vomit” at a rate of 3.3%.

Discussion

This study is the first to investigate the knowledge, attitudes and concerns of society regarding CPR in Turkey.

According to the results obtained from a population having a high level of education in the western region of Turkey, the rate of people who received CPR training was found to be 40.3%. This rate may be lower in rural regions. Different countries have conducted several studies in their societies to determine the knowledge, attitudes and awareness regarding CPR. This rate was reported to be 69.4% in a study conducted in Slovenia; the researchers attributed this to the obligatory CPR training in driving schools in this country (10). However, although their CPR training rate was high compared with the other countries, the researchers found the rate of participation in knowledge update courses to be 2%, and they indicated that this rate was too low. CPR training rates in other countries were as follows: 21% in Hong Kong, 27% in New Zealand, 28% in Ireland, 35% in Japan, 58% in Australia, 64.1% in West Australia, 75% in Poland and 79% in Washington (1218). These rates vary in the urban and rural regions of the countries. While the training rate in an urban region of Arizona was 63.2%, this rate fell to 55.4% in the rural region (19). Taking CPR training during driving schools is obligatory in some of these countries. BLS and first aid training are provided in health education courses during driving schools in Turkey. Further, 7.3% of participants stated that they received CPR training during a driving school in Turkey. Following this was receiving CPR training at courses given in the workplace, with a rate of 8.4%. It was made obligatory in the Law on Occupational Health and Safety No. 6331 in July 2013 in our country that one out of 10 employees working in a workplace receives a BLS certificate from courses that are approved by the Ministry of Health. The rate found in this study may be related to this number, and it may increase.

The rate of knowledge of cardiac arrest signs was found to be statistically higher in participants who have received CPR training than in those who have not received it. This result clearly shows that education is an important factor in recognizing cardiac arrest signs. However, the rate of knowledge of at least one cardiac arrest sign was 17.8, and this rate was reported to vary between 11.2% and 31.4% in studies conducted in different countries (10, 13). The rate of knowledge of cardiac arrest signs was reported to be 78% in a study conducted among teachers in Belgium (20). This high result demonstrates the effect of education. CPR training courses are found in the curricula of primary and secondary schools in countries such as Austria, Japan, Norway, Hong Kong and Singapore. In a study, the rate of willingness to begin CPR by citizens was found to be high in people having a high level of education and in those working at offices or jobs necessitating such skills (12). It was suggested by studies that these results are not related to the responsibility the citizens bear toward their workmates but are related to CPR awareness (12).

In this study, 35.5% of participants stated that they could perform only cardiac compression and 28.7% stated that they could perform both cardiac compression and mouth to mouth ventilation. These low rates may be because of the low rate of training and because of the lack of repeat BLS training courses. These results explain the low rate of CPR (3.6%) that was initiated by witnesses. In our study, 18.6% of participants stated that they had previously witnessed sudden cardiac arrest; however, 78% of them hesitated to apply CPR because they could not rely on their knowledge and were afraid to make a mistake. However, most participants stated that they volunteered to correct and improve their CPR knowledge and skills. In a survey study conducted in Japan, 19% of 1132 people were reported to have witnessed a collapse situation, and 4% of these began to apply CPR (12). In a survey study in which 357 people participated, the rate of receiving CPR training was 12%, and 10% of the participants stated that they had previously performed CPR. It was revealed in previous studies that in addition to increasing knowledge and practice, CPR training with repeat courses has a positive contribution to initiating CPR more willingly when a citizen witnesses a cardiac arrest (10, 12, 21).

When CPR practical application knowledge, such as compression application location, number, depth and rates of compression–ventilation, were evaluated, the rates were found to be significantly higher in participants having received CPR training than in those who had not received CPR training. Rajapakse et al. (10) reported that 1.2% of participants knew the correct number of compressions, 2.2% knew the ventilation–compression rate and 13% knew the compression depth. However, the rates of knowledge of BLS procedures were not given according to training status but were given in general.

In the evaluation of CPR attitudes and concerns in societies, it was found that participants were reluctant to perform CPR because of contagious diseases and legal reasons in societies with high education levels (9, 15, 19, 22). Although CPR education rate was 70% within the last 5 years in Ireland, 16.6% of participants stated that in an urgent case, they would initiate CPR without the fear of lack of safety, being sued, or contracting infection (15). In a survey conducted in Arizona, participants specified that they were reluctant to perform CPR because of being afraid of making a mistake (22.8%), causing harm to the patient (19.3%) and legal reasons (17.7%) (19). In addition, according to the results of many studies, while the rates of participants stating that they could apply CPR without hesitation mostly to their families and friends is between 72% and 93.3%, the rates of participants stating that they could perform CPR on a stranger vary between 18% and 42% (16, 23). In our study, the response rate for the question regarding the people on which participants could perform CPR without hesitation was found to be 90.6% for someone from their family but 42.5% for a stranger, which is similar to the results of previous studies.

In a study conducted by Urban et al. (24), they highlighted that compressions were discontinued by both citizen and professional rescuers due to their unwillingness to perform mouth-to-mouth ventilation; therefore, they emphasized that more efforts must be made to increase education, and more rescuers must be educated using mass media in education, programs and videos. Atkins specified that CPR education must reach the masses with creative approaches in easy, accurate, rapid and inexpensive ways. The use of smartphones and tablet PCs, which are common communication instruments in today’s world, must be developed to contribute to standard CPR education (21).

Our study has some limitations. One of these is that it was conducted only in the western region of Turkey and did not involve the whole country. Another limitation is that AED is available only in airports in our country. It is unavailable in public places such as subways, highways, football stadiums and large entertainment centres. Therefore, the participants were asked what they knew about AEDs but were not questioned about its detailed use. The answer to the question on what they knew about AEDs was “I have never heard of it” at a rate of 58.5%. It can be suggested that the participants who said “yes” to the question “Do you have any idea about where an AED is found?” (21.8%) might have answered this question inaccurately because they confused AEDs with defibrillators that are available in hospitals.

Conclusion

The knowledge and awareness level of CPR among adults in society can be increased by generalising CPR training to the public; by this means, the rate of witnesses who start CPR can be raised. Repeating this training at certain intervals will reinforce CPR training in society. To do this, the campaigns raising awareness of CPR training should be increased. A campaign targeted to raise awareness of cardiac arrest in society was started at the request of the European Parliament and ERC on 16th October 2014 in Turkey. It is planned to continue this campaign for 2 years.
