Awareness of basic life support among medical students in Syria, Iraq and Jordan: a cross sectional study

doi:10.21203/rs.3.rs-584155/v1

Background: Sudden cardiac arrest is one of the most leading causes for death in all over the world. Basic life support (BLS) training rates vary worldwide, there is a general scarce in the number of Surveys which evaluate knowledge, and awareness about BLS in Middle Eastern countries students especially Jordan, Syria and Iraq. The purpose of this study is to evaluate the awareness of basic life support among medical students.

Methods: A Cross sectional web based questionnaire study was conducted in November 2020. The study included 2114 medical students in Syria, Iraq and Jordan. We evaluated BLS skills according to total mean score of correct answers. The participants were classified according to gender, residence, country, University, academic degree, and academic stage to study their effect on the participants’ BLS knowledge. A chi-squared test was used to determine if there were differences between those who attended a basic life support course and those who did not.

Results: 1656 of the participants (78.3%) stated that they did not attend a basic life support course. There was a significant difference between the participants from different countries where the mean score in Syria, Jordan and Iraq was 18.3, 24.3 and 18.8 respectively (p < 0.05). The participants were divided into 3 level according to total score; low (0-12), moderate (13-24) and high (25-37). In total, 18.3%, 72.8% and 8.9% of participants had high, intermediate and low level respectively.

Conclusion: The overall knowledge of basic life support among medical students is not adequate and need significant improvements. This study showed that an attendance a basic life support course previously had an effect on knowledge level. Hence, there is an urgent need to apply basic life support courses into the pre-clinical stage at universities.

Sudden cardiac arrest is one of the most leading causes of death in all over the world. However, Basic life support (BLS) including cardiac pulmonary resuscitation (CPR) is the appropriate management. [1] BLS technique recognizing includes many signs; cardiac arrest, stroke, foreign body airway obstruction, heart attack and defibrillation with an automated external defibrillation (AED). [2] [3] Neonates and infants can also be seen with cardio- respiratory arrest [4]. Therefore, health care provider should know the differences in BLS algorithm.

BLS training rates differentiate worldwide, there is a general scarce in the number of Surveys which evaluates knowledge, and awareness about BLS in Middle Eastern countries students especially Jordan, Syria and Iraq. In a study evaluating knowledge and awareness towards CPR among university of Riyadh students in Saudi Arabia found that 31% did not have any prior CPR skills knowledge. 85% of those with preceding knowledge felt that it was insufficient. Overall, 88% of students want to learn how to perform CPR. [5] Another Egyptian study from Al-Azhar medical schools showed that among all included students, only 27% had previously attended BLS course, and only 34.3% reported that they had completed a course before. [6]

Inadequate confidence in performing BLS has also been reported among medical students in Europe [7], and insufficient training among medical students in U.K and Poland has also been documented. [8][9]

There is a big shortage of emergency medical professionals in Syria, Iraq and Jordan, it is very essential to teach the student about BLS principles. This cross sectional study aims to assess the perceptions about BLS among Syrians, Jordanians and Iraqis medical students because there are no enough studies related to BLS has been reported from the three countries.

Study design, setting and data collection:

A cross sectional web based questionnaire study was conducted in November 2020. The study included six universities from Syria, ten universities from Iraq and six universities from Jordan. We distributed the questionnaire in all universities, including pre-clinical and clinical years, via official Universities groups on social media. The study was conducted through an electronic questionnaire due to COVID19 pandemic. The students read the purpose of the survey before answering the questionnaire, and the participation was voluntary and anonymous. The total number of participants was 2114, and the power analysis was not performed.

The survey:

We designed a closed ended, electronic questionnaire depending on review of pertinent literature [6] [10] and the latest American Heart Association (AHA) guidelines for BLS. The survey was piloted on 20 students, which was easy to understand, except for one question of the second section for that have been deleted. The students in the pilot study were excluded from data analysis. The questionnaire included 4 sections. The first section collected demographic data (age, gender, country, residence, university, academic year, academic degree and attendance a BLS course previously). The second section consisted of 19 questions to assess the participants` knowledge and awareness about BLS (i.e., assessment of airway, breathing, CPR technique, AED use and dealing with victims of drowning and choking). The third section consisted of 18 questions about indications of cardiopulmonary resuscitation, signs of successful CPR and suitable response in case of emergency situations. The latter section consisted of 5 questions about the participants' opinions of their ability to apply basic life support. We also inquired about importance of applying basic life support education in the first and second years in medical colleges. Firstly, the questionnaire was written in English. Afterwards, we translated it to Arabic because it is the local language. We reported the English version of the study in additional file 1. The dean of the faculty of medicine at Aleppo University approved the survey, which was compatible with the Declaration of Helsinki.

Statistical analysis:

Data analysis was done by using SPSS version 26. We gave each question (second and third section from questionnaire) one point and calculated the total score which was 37. The participants were classified according to gender, residence, country, University, academic degree, and academic stage to study their effect on the participants’ BLS knowledge. We performed descriptive statistics to calculate the number of participants (percent), mean of score, standard deviations, minimum and maximum value for each sub-group. Independent-samples T test and one-way ANOVA were used to evaluate and quantify the association between the categorical outcomes. A chi-squared test was used to determine if there were differences between those who attended BLS course and those who did not attend it regarding CPR skills. P < 0.05 was considered significant.

Demographic characteristics:

A total of 2114 participants completed the questionnaire, 1204 of them were from Syria, 433 were from Jordan, 477 were from Iraq. 1174 (55.5%) and 940 (44.5%) of the participants were females and males respectively. 1223 (58.3%) of the participants were in pre-clinical stage and 881 (41.7%) were in clinical stage. We found that the majority of participants did not attend a BLS course (78.3%). Table 1 demonstrates student demographics.

BLS knowledge:

When we compared the mean score between the sub-groups, we found that there was no significant difference in mean score among males (19.8) and females (19.5). In contrast to gender, there was a significant difference among the participants from different country where the mean score in Syria, Jordan and Iraq was 18.3, 24.3 and 18.8 respectively (p < 0.05). In addition, there was a significant difference among the participants according to their residence, University, academic degree, and academic stage. (Table 2)

The participants who attended BLS course had a higher mean score 21.6 in compare with who did not attend 19.1 (p < 0.05). (Table 2)

CPR skills:

We compared between the knowledge of the participants who attended previously BLS training and who did not attend a course especially in some domains of CPR (massage rate, massage location, and massage depth, massage/ventilation ratio). In comparison between those who underwent BLS training and those who did not undergo BLS training, 82.5% and 50.6% of them reported that they knew the pressure/ventilation ratio respectively. We found a significant difference between the two groups in all domains (P < 0.05). (Table 3)

The participants were divided into 3 level according to total score; low (0–12), moderate (13–24) and high (25–37). In total, 18.3%, 72.8% and 8.9% of participants had high, intermediate and low level respectively. (Fig. 1)

Perception of the medical students toward BLS:

36.2% of the participant were not confident of performing CPR and about 70.3% were uncomfortable to be in a situation that requires performing CPR. Moreover, about 59.1% of the student assessed themselves 5 or less in a self-assessment of mastery of Basic Life Support. (Table 4)

It is important for all medical students to learn about BLS as they can face life-threatening emergencies in their daily life. The American Heart Association recommended that everyone should be given training of the BLS regardless of their study or specialization. [11] Recently, several publications have highlighted the deficiencies in BLS knowledge among medical students [12] [13]. We found that in our study, no student was able to answer all the questions correctly. However, Jordan has better results than Syria and Iraq in total. Jordan had a higher mean score (24.2) than Syria (18.3) and Iraq (18.9). In comparison between the three countries, 61% of Jordanian students have high level while 82.8% and 85.3% of Syrian and Iraqi students respectively have moderate level. This can be justified due to the lack of training centers in Syria and Iraq due to the internal crisis. Additionally, Jordan has a better education system. Regarding BLS training, the results showed that 21.7% of the participants stated that they had received BLS training, lower than reported in Oman (35.2%), [13] Egypt (27%), [6] Saudi Arabia (22.5%) [14]. Conversely it was higher than reported in India (18.9%) [10] and Pakistan (14.7%) [15]. All health-care staff in the US were recommended to receive BLS training routinely since 1966. [16] In general, our study showed a lower percentage of trained medical students in comparison to other countries. Consequently, there is a necessity to train the medical students in BLS skills to bring Syria, Iraq and Jordan in line with international norms. The results showed that the gender had not an apparent effect on knowledge level. Similar result reported in Saudi Arabia [14] but another studies in France showed a difference between males and females [17]. In contrast to gender, the results showed that attendance a BLS course previously had significant effect on knowledge level. Similar results were reported from Oman, [13] United Kingdom, [18] Pakistan [15] and Thailand [19]. In this study, the numbers of participants who received training in BLS and had knowledge of CPR (massage rate, massage location, massage depth and massage/ventilation rate) were higher than those who did not receive training. Although about 72.8% of participants had an intermediate level, most of them (77%) wanted to avoid/were uncomfortable and about (36.2%) were not confident of CPR performing similarly to the findings that have been reported from India [10] and Europe. [20] A Syrian randomized controlled trial study revealed that peer-led training in BLS for medical students in pre-clinical years is sufficient in comparison with health professional-led training. [21] Consequently, it can be effectively performed in bad situations of crisis such as in Syria. Therefore, the individuals could be benefit from medical students to increase their BLS skills. When we asked the participants about BLS training, 82.8% of the participants agreed to apply BLS training during the first and second year of the university. Altintaş et al also showed that 75.6% of the participants stated that they could apply BLS confidently in real situations after receiving training. [22] According to Pande et al there is an increase in mean score of BLS knowledge from 3.42 to 7.42 one week after the BLS training attendance among first year medical students. [23] The knowledge of BLS may decrease in the 6 months following the training as seen in Winchana et al study. [19] Therefore, students should constantly review BLS principles continually and keep up to date with the latest guidelines. Regarding universities ranking, the results showed that universities in Jordan achieved the first six ranks, while there is only one Syrian university among the top 10 universities. (Table 5) We can explain that by good educational system in the Jordanian universities which exceed the universities of Iraq and Syria, depending on Webometrics Ranking of World Universities. [24] Finally, we encourage to benefit from different media (television, internet) to realize, emphasize and enhance the importance of BLS principles in our life because of their large audience as seen in a study from Saudi Arabia showed that the most common sources of CPR performing are television and movies. [25] Additionally, a well trained personnel programs via media will have a positive influence on public health for the society. The morbidity and mortality can be reduced by training medical students at an early stage that also enhance the student's confidence to face many emergency situations and act appropriately. To achieve this goal, the educational system should be developed by depend on American Heart Association (AHA) guidelines in the educational curriculum. Practical courses and training on mannequins is recommended to master the basics of BLS.

The major limitation of this study was the data collection technique through the use of an online questionnaire distribution. We did not design practical tests to assess students’ experiences. Another limitation was the heterogeneity of the participants among countries, where the number of students was the largest from Syria. Moreover, we did not include all universities in the three countries.

The results indicate that medical students’ knowledge toward BLS is significant and requires more effort. In addition, this study showed that an attendance a BLS course had positive impact on knowledge level. Hence, there is an urgent need to apply BLS courses into the undergraduate curriculum, particularly in pre-clinical stage. In general, Jordan had better results than Syria and Iraq, indicating that more focus is needed to increase the level of knowledge among medical students in BLS skills to bring these countries in line with international norms.
