ABSTRACT
Aim:
This study aimed to determine the knowledge level of nurses, emergency medical technicians, and paramedics about the basic and advanced life support guidelines in children.
Materials and Methods:
The study was conducted between July 2018 and August 2018, with 602 volunteer healthcare professionals, in Gaziantep of Turkey province of Turkey where the pediatric population is high. Following the 2015 guidelines of the American Heart Association, a questionnaire about basic and advanced life support in children and demographic data was administered. Statistical comparisons were made between the groups.
Results:
Of the 602 participants, 62% were male. The average age of the participants was 28.4 (minimum-maximum, 18-50) years. The basic and advanced knowledge scores of the nurses were lower than those of the emergency medical technicians and paramedics. Those who work in pediatric emergency departments and pediatric intensive care units, with 5-8 years of experience, and paramedics had high advanced life support scores and total knowledge scores. The basic life support knowledge scores and total knowledge scores of those with certification were good, but the advanced life support knowledge score was inadequate.
Conclusion:
The basic and advanced life support knowledge scores of the professionals were moderate, and the total knowledge scores of the nurses working in pediatric services were low. While basic life support knowledge scores of the paramedics and professionals working in emergency departments and child intensive care units were low, their advanced life support knowledge scores were high.
Introduction
Cardiac arrest; It is the cessation of respiratory and cardiac activity for many reasons, especially respiratory problems in children. Cardiopulmonary resuscitation (CPR); defined as life-saving procedures for airway safety and respiratory and circulatory support following cardiac arrest (1).
According to the American Heart Association (AHA) guidelines-Basic Life Support (BLS) guideline, children (between 28 days and 18 years old) who do not respond to environmental stimuli, are not breathing or breathing poorly, have no central pulse, or have a central pulse ≤ 60/minute should be evaluated within a maximum of 10 seconds; help should be called, respiratory and compression support should be started and applied synchronously (1-3). When there is a rescuer, 30 chest compressions, and in case of double rescuer, 15 chest compressions followed by 2 breaths should be applied. During each compression, the rib cage should be collapsed at 1/3 depth and allowed to stand back to create an effective pulse in the patient. Chest compression should be 100-120/min for patients with advanced airway support. Patients should be ventilated asynchronously for 10 sec/min for each ventilation (1,4).
The goal of performing CPR is to reach the patient’s previous quality of life (1,4,5). With the developments in emergency care and first aid methods in children; It was reported that discharge after CPR reached from 24% to 43% (1,4-6). Early detection of the life-threatening situation in the child services and early warning of the emergency team, and the correct implementation of the first and emergency aid can increase the success of CPR and decrease mortality and sequela rates (2,3,5). In some studies, it is stated that even if only effective compression is performed, success has increased by 10%, and good neurological results can reach 60% with high quality CPR application (1,5,7).
Survival and neurological good results; the patient’s age, comorbidity, time of arrest, time to first aid, adequacy of medical team and equipment, high quality CPR application and post-resuscitative care are directly related (1,8-10). Turkey in practice in order to increase the success rate of CPR according to AHA guidelines, the children basic and advanced life support courses are organized and maintained the certification.
In this study, in Gaziantep province in Turkey where child population is high, it was aimed to determine the level of knowledge in nurses, emergency medicine technicians and paramedics who is dealing with pediatric patients according to the basic and advanced life support guide AHA-2015 Guide in children with the latest updates.
Materials and Methods
This study planned as a cross-sectional descriptor; Between July 2018 and August 2018, it was conducted in three big hospitals of Gaziantep Turkey (Gaziantep Cengiz Gökçek Gynecology and Pediatrics Hospital, Dr. Ersin Arslan Training and Research Hospital and 25 Aralık State Hospital). One of the study centers; the children’s hospital accepts about 250,000 children patient per year; on the other hand, Dr. Ersin Arslan Training and Research Hospital and 25 Aralık State Hospital accept an average of 50,000-75,000 children patient per year. Nurses, emergency medical technicians and paramedics; who works in the child emergency departments, child intensive care units and child services of these hospitals and who works in the ambulance service and emergency health department operations and coordination center of the province were included in the study. Those who did not give care about pediatric patients and those who were temporarily assigned to these units from other centers were excluded from the study. Health workers other than nurses, emergency medical technicians and paramedics were excluded. The data were collected through a 16-question survey form. Descriptive features such as age, gender, occupational title, year of employment in the profession, the department they worked in and basic and advanced life support certification status; asked as multiple choice or open-ended questions. In the second part of the survey, the participants were asked ten multiple choice questions to measure their level of knowledge about basic and advanced life support in children. By giving “one point” to each information question that is answered correctly; basic life support evaluated by 5 points over 5 questions; advanced life support was evaluated 5 points over 5 questions and life support total knowledge level score was evaluated finally over 10 points. Based on the total score; It was evaluated as “0-2 points: bad, 3 points: medium, 4 points: good, 5 points: very good”. Knowledge level questions were prepared by the researchers with reference to the AHA 2015 guidelines-BLS (1). Permission was obtained from the institutions where the study was conducted in order to conduct the research. Ethics committee approval was obtained from the Local Non-Interventional Clinical Research Ethics Committee of Gaziantep University (no: 2019/148, date: 03.04.2019). The participants were informed about the study, their verbal and written consent was obtained and the study was completed on a voluntary basis.
Statistical Analysis
SPSS 23.0 package program was used for statistical analysis of the data. Categorical measurements were given as numbers and percentages, while continuous measurements were given as mean, deviation and minimum-maximum. The suitability of variables to normal distribution was evaluated using visual (histogram and probability plots) and analytical methods (Kolmogorov-Smirnov/Shapiro-Wilk tests). Mann-Whitney U test was used in binary variables and Kruskall-Wallis test was used in more than two variables. Bonferroni analysis was used in Post-Hoc analysis to determine the source of the difference between the groups. Spearman correlation analyzes were applied for correlation analysis between the scales. In all tests, p<0.05 was considered statistically significant in all tests.
Results
Seven hundred fifty healthcare professionals (HPs) who met the criteria of the study were reached, 602 of them voluntarily participated in the study. In the study, 378 (62%) of the participants were male and the average age of all participants was 28.4 years (min-max: 18-50 years). On the other hand, nurses with 414 participants were 68.8% of whole group. Four hundred and thirty-three (73%) of the participants had less than 8 years of experience in their fields. One hundred and fifty-two (25.2%) of the participants had a basic and advanced life support certificate. Demographic characteristics of HPs are given in Table 1. The answers to basic and advanced life support questions and the evaluation of the scale scores used are given (Figure 1).
A weak positive correlation was found between basic life support knowledge scores (BLSKS) and advanced life support knowledge scores (ALSKS) subscale dimensions (r=0.256). It was determined that there was a strong positive correlation between BLSKS and the total knowledge scores (TKS) (r=0.811) (p=0.001). There was also a strong positive correlation between the ALSKS subscale size and the TKS (r=0.773) (p=0.001). Average values of scale scores are given in Table 2.
Gender and scale scores of health professionals and their differences were not statistically significant (p>0.05). The ALSKS [mean ± standard deviation (SD)=3.24±1.04] and TKS (mean ± SD=6.27±1.81) of the HPs who aged 28-32 years, were higher than the other groups, and these scores were found to be statistically significantly higher compared to other age groups (p=0.001, p=0.022, respectively). The ALSKS (mean ± SD=3.20±0.96) and TKS (mean ± SD=6.33±1.71) of those who have worked and experienced in their fields for 5-8 years are higher than the other groups, and the statistically significant difference is due to this group (p=0.017, p=0.027, respectively). It was found that paramedics’ BLSKS (mean ± SD=3.33±0.97), ALSKS (mean ± SD=3.10±1.10) and TKS (mean ± SD=6.43±1.64) of paramedics were higher than all other groups, and this difference was statistically was found to be significantly higher (p=0.000, p=0.049, p=0.009, respectively). When the HPs with basic and advanced life support certificates are compared; It was observed that BLSKS was higher in those with certification, but ALSKS was not different between groups (p=0.008, p=0.725, respectively). While the BLSKS of those working in the ambulance service was higher, the ALSKS of those working in the emergency department-child intensive care units was higher. In Table 3, all the relationship between the demographic characteristics of HP and their scale scores is given. Eighty-three (54.6%) of 152 healthcare workers with certificates were employed in the ambulance service; 194 (43.1%) of 450 healthcare workers without certification were found to be working in the general services. Certification information is given in Table 4 according to the units in which HPs work.
Discussion
Our study is the first study which covers hospitals in a large city where have many of the child population. Also, our study included the largest participants in Turkey. Our results shows that the participants’ who are young group with moderate experiences BLSKS and ALSKS are moderate. On the other hand, paramedics’ ALSKS and TKS were “good” in terms of level. While the ALSKS of the HP working in the emergency departments and child intensive care units were good, thoughtfully, their BLSKS were insufficient. It was also determined that the HPs working in the general service had low TKS and the certification contributed positively to BLSKS and TKS, but had no effect on the ALSKS.
Nurses spend more time with the patient in the hospital services due to their duties. Paramedics and emergency medical technicians greet the patient first on the field. Therefore, they can only take part in the starting minutes of the CPR, which is directly related to the prognosis (3,6). In the literature, it has been reported that the basic knowledge of CPR of nurses is low-medium in general even in developed societies. Frequently CPR trainings have been pointed out (11-19).
The HPs between 28-32 ages are good at advanced knowledge score (AKS) and TKS. It can be explained by the fact that they were mostly working in the emergency departments and child intensive care units, and also have moderate (5-8 years) professional experience. It suggests that the hospitals’ management may have made their plans especially in this direction in departments with dynamic functioning.
In this high-participation study shows that the professional experience has not made a difference in BLSKS. The professionals with moderate experience were better in ALSKS and TKS. This could be explained by the fact that the information has been obtained through more practice. It is found that the ALSKS of the HP working in the emergency departments and child intensive care units, which frequently encounter critical pediatric patients, is good and the BLSKS is insufficient. It can be explained by the fact that there are always doctors in these departments, airway safety is provided early and more advanced life support is provided. This also supports that information may have been acquired through practice. Unlike in the literature, Örsal et al. (20) study with the participation of 78 nurses stated that nurses have >10 years of experiences have higher BLSKS and ALSKS. Aygin et al. (21), study with the participation of 97 nurses stated that the knowledge level of nurses working in education and research hospitals was higher.
In our study, at all levels of knowledge of young and less experienced (<4 years) HP does not make any difference, suggests that the information learned in schools may be forgotten in a short time. In the literature regarding CPR trainings, It was stated that the trainings contributed the knowledge of HP but the information gained was forgotten in a short time such as 3-6 months and it could not be reflected in the skill completely (2,11,22-24). Similarly, Şener et al. (25) stated that school knowledge continued in the first years of graduation, but experience was at the forefront in the coming years.
Our study is composed of interested participants with pediatric patients only, it is the first study to compare different occupational groups on that issue in Turkey. The lower BLSKS of nurses than emergency medical technicians and paramedics suggests that they may not have updated critical patient management information in routine working conditions. Paramedics have higher advanced knowledge than other groups, it can be explained by their education is more focused on critical patients and they are more active in the critical field due to working conditions. Therefore, it may be beneficial to review the sections on critical child patient management in nursing education program.
In Turkey, in order to increase the success rate of CPR practices, basic and advanced life support in children courses are organized and certification of health workers is done. According to our study, the certification programs have contributed positively to BLSKS and TKS. Therefore, repeated training activities can be more beneficial. On the other hand, the fact that having a certificate did not make a difference in ALSKS. It also suggests that educational activities are more focused on basic life support issues. It may be beneficial to expand the programs by including the evaluation of the course achievements with detailed feedback. On the other hand, facilitation of the transfer of information and the learning of team members could be done by planning of simulation-based trainings (26). Increasing the number of courses, updating the training program and holding case meetings involving the whole team can contribute to the improvement. These meetings could be a step in increasing the quality by strengthening team dynamics.
When the departments are analyzed, HPs (mostly nurses) working in the general pediatric service have a poor TKS compared to others. It is noticed that the renewal of knowledge during routine work is insufficient and they continue to their work with the former knowledge. We think that nurses should be more involved in training on critical patients and their motivation in this regard should be increased.
Study Limitations
The study reflects the knowledge level of HPs but does not include skills and self-assessments. The study shows only the results of HPs who work in those three large hospitals with high patient populations and working in the city’s emergency health services of Gaziantep which is the one of major cities of Turkey. In addition, it does not reflect the knowledge levels of other HPs who do not care for pediatric patients and who do not work as nurses, emergency medical technicians and paramedics. It is also among the other limitations of the study that the HP who have a certificate could not learn the certificate update dates.
Conclusion
This study; It has shown that HPs’ basic and advanced life support knowledge levels are not at the desired level. Also; It has shown that the knowledge levels of HPs working in different fields of hospitals are different from each other and that staffs do not follow up-to-date information about that. We think that the scope of trainings in both universities and hospitals should be revised and their frequency should be increased.
