Simulation Use in Respiratory Therapy Programs in Saudi Arabia: Results of a National Survey
Abstract
Background
The use of simulation-based methods for teaching and learning in the education of health professions is increasing, but its prevalence in Saudi Arabia among respiratory therapy programs has yet to be investigated. The purpose of this study is to identify the use of simulation-based learning (SBL) in respiratory therapy programs in Saudi Arabia.
Methods
A cross-sectional study was performed by sending Google forms survey via Email to directors of respiratory therapy programs in Saudi Arabia (N=16) to evaluate how each one used simulations as an educational tool.
Results
The survey was returned with a total response of 12 out of all 16 program that were initially contacted (75% response rate). Among the respondents, approximately 75% of the programs are using SBL, while high-fidelity simulation is used by all programs. The present data show that 67% of the respiratory therapy programs has a space for simulation within the department, while 33% utilizes institutional simulation centers. For short simulation scenarios, debriefing is not conducted in 67% of the programs. There is acceptance by program directors that simulation hours should be counted towards clinical hours. About 67% of respondent programs have mandatory simulation learning activities, and 100% agree that simulations should be used more. However, lack of training and shortage of staff are among barriers to increase the use of SBL.
Conclusion
SBL is commonly used and relatively varied among respiratory therapy programs. However, it requires some improvements in several aspects, including the use of debriefing and increasing the number of properly trained staff.
Introduction
Simulation in clinical settings can be defined as tools, devices, or environment that help mimicking real situation.1 Simulation in general is considered to be safe and useful method for teaching and learning. It helps avoiding risks that might be encountered by instructors, students, and subjects involved in the training.2 Therefore, simulation is considered an excellent educational tool to gain and enhance clinical skills. It is well documented that use of simulation for clinical education has significant impact on the learning outcomes. It has considerable effect on knowledge acquisition, gaining and enhancing skills, and behaviors related factors.1 Moreover, Arias et al reported that simulation adds greater significant accuracy to the intended learning skills.3 However, others stated that it might not be necessary to cause significant improvement in performance.4
Simulation-based learning (SBL) is defined as active and immersive learning activity, which occur in virtual learning environment but resemble real-life situation.5 Over the last decades, SBL in healthcare has grown in popularity. As the demand for training grows, more universities, colleges, hospitals, and even standalone simulation centers were established around the world. In Saudi Arabia, SBL is rapidly developing due to the expansion of healthcare specialties, increased training needs, and the availability of resources across many healthcare professions, including respiratory therapy.6 Respiratory therapy programs are well established in Saudi Arabia,7,8 and their use of SBL is reported to be a suitable alternative to some of the bedside clinical practices where critical interventions are vital, especially in intensive care units for neonates, pediatrics, and adults. Therefore, there is need to use different simulation methods like high-fidelity task trainers, low-fidelity task trainers, and computer-based simulation to perform procedures like intubation, extubation, arterial puncture, and mechanical ventilation management. The learning outcomes of using different simulation methods particularly high fidelity versus low fidelity simulation were inconsistent. It was reported to be in favor of low fidelity simulation,9 While others showed it is in favor of high fidelity simulation.10
In Saudi Arabia, early clinical exposure for the majority of respiratory therapy programs is considered vital component of the programs’ learning objectives.11 Early exposure to clinical practice, if not properly managed, can negatively affect student’s experience, confidence, and learning outcomes.11 SBL was reported to enhance theoretical knowledge and clinical practice together.12 It also can improve student’s personal skills, such as leadership, communication, teamwork, decision-making skills13 and critical thinking.14 More importantly, students can be closely supervised, so their overall performance is fully monitored using realistic clinical scenarios without risks to the patient.15
Currently, SBL is utilized across many disciplines in the healthcare field as a tool for teaching and learning.16 In Saudi Arabia, several investigations have aimed to explore the utilization of simulation in teaching and learning in medical schools.17–20 The purpose of these studies ranged from identifying utilization of SBL to measuring satisfaction of learners and instructors. Also, in nursing programs, it was reported that SBL improve learners’ knowledge, confidence, and satisfaction.21 Similarly, in the United States (US), some healthcare specialties such as paramedics and nursing have utilized SBL on their educational programs. But in respiratory therapy profession, the utilization of SBL is less compared to these professions.22–24 While in Saudi Arabia, up to the authors’ knowledge, the utilization of SBL within the respiratory therapy programs was not investigated. Therefore, the aim of the present investigation is to identify utilization and efficiency of SBL in respiratory therapy programs in Saudi Arabia.
Materials and Methods
Study Design and Participants
Qualtrics survey was utilized with permission from previously published study.24 The development of the survey was explained on previous reports.24,25 It contains 23 item that involve multiple-choice, “select all that apply”, and free-text responses. The survey was divided into several categories including demographics, debriefing, modalities, accreditation, and recommendations for equivalent clinical time. The debriefing was defined as an organized meeting following the clinical simulation scenarios to discuss participants’ performance and promote the learning outcomes.26 It is interactive, reflective and bidirectional discussion between trainers and learners.27,28 The SBL activities were defined to include methods like high-fidelity simulation with a mannequin, task trainers simulations, and screen-based computer simulation. Some examples of these methods include arm simulator to extract arterial blood samples, adult and neonatal resuscitation-training mannequins, and airway mannequins for tracheal intubation. Box 1 shows definition of different types of simulation which were adapted from previous study.24 The simulation definitions were shown to participants at the top of the survey.

Data Collection
A report published in 2016 showed that there are 14 respiratory therapy program in Saudi Arabia.7 However, five of these programs were phased out. It is worth noting that one of the phased out programs was reactivated. But, this was not reflected on their official website. Therefore, it was missed out. Additionally, the official websites for colleges and universities were searched to identify active respiratory therapy programs. A total of 16 respiratory therapy programs were identified. The survey was sent using google form link through Email to each respiratory therapy program director in Saudi Arabia (N=16) in March 2022 and followed up until May 2022. Email contacts were obtained from the official websites of each institution. To exclude any repeated responses, the Email addresses of all institutions in Saudi Arabia were selected, and a restriction was activated to allow only one response per institution. Moreover, all respiratory therapy program directors were contacted through the phone and informed about the survey and the purpose of the study. A total of 12 non-duplicated surveys were received (75% response rate). Program directors give their consent to participate by their agreement to take part of this survey. Ethical approval was obtained from faculty of medical rehabilitation sciences’ ethics committee, King Abdulaziz University. Data were anonymized by removing any personal information for the purpose of confidentiality.

Table 6 presents the utilization of simulation training as a form of clinical training. The vast majority of the respondents (78%) believe that the simulation hours should be counted towards clinical hours. Some of the respondents agree that the number of simulation hours is equivalent to clinical practice, while others indicate that there should be more clinical practice than simulation. Respiratory therapy programs considerably differ in how they count the ratio of simulation hours to clinical hours.

Discussion
The present data show that majority of respiratory therapy programs in Saudi Arabia use at least one type of simulation, and high-fidelity simulation is the most predominant. High-fidelity simulation and task trainers are the most common types utilized within respiratory therapy curricula. Almost two-thirds of respiratory therapy programs utilize simulation within their departments. The present data imply that respiratory therapy programs’ directors and educators are investing in clinical simulation to improve clinical and nonclinical skills. Despite challenges and barriers that preclude maximum utilization of simulation, the present study offers evidence that some types of simulation is embedded within the respiratory therapy curriculums.
Debriefing is utilized by all respiratory therapy programs but considerably varied in time among these programs. Interestingly, the vast majority of respiratory therapy programs agree that simulation training hours should be counted toward clinical training. This would enable learners to enhance knowledge and master competencies with no risks to patients. It is well established that simulation is an excellent tool for learning and performance assessment.29–31 Therefore, more simulation training hours can safely replace clinical training hours. Also, directors of all respiratory therapy programs that utilize simulation in training agree that they need to invest more in simulation. They list shortage of staffing and lack of formal training among the most common barriers that preclude more utilization of simulation. Majority of programs’ directors state that faculty need to be trained in writing simulation scenarios, debriefing, and facilitating simulation.
The present investigation has shown that majority of respiratory therapy programs in Saudi Arabia utilize SBL. Similarly, it was reported that more than three-quarters of respiratory therapy programs in US utilize SBL.24 In both countries, the most common courses utilizing SBL are foundations of adult therapeutics, patient assessment, adult critical care, and neonatal and pediatric respiratory care. However, utilization of computer-based programs is more prominent in respiratory therapy programs in US than in Saudi Arabia. In US, limited development of faculty in simulation use is reported to be one of the major barriers to implement SBL. Almost, half of the respondents did not receive any faculty development in designing simulations, programming, and debriefing.24 Similarly, in the present data, 90% of the respondents indicate that there is a need to train faculty in simulation utilization. Proper faculty training in simulation has the potential to improve their knowledge, skills, and confidence. This presumably would improve the quality of simulation application and expand its utilization. We agree with Davis et al24 that lack of faculty development programs can be attributed to shortage of financial resources, time, or lack of recommendations that support usage of SBL in respiratory therapy programs.
It is clear that respiratory therapy programs are behind medicine and nursing programs in terms of utilizing simulation on their educational training. This is supported by the present data. This is also evident in the absence of faculty development programs that enable them to utilize simulations efficiently. The present data are in line with other studies indicating that lack of knowledge in simulation design, implementation, and debriefing among faculty are barriers which preclude more utilization of simulation in respiratory therapy programs.24,32 Therefore, implementation of faculty development programs in simulation are required. These programs should aim to improve knowledge and enhance skills in facilitating SBL, writing simulation scenarios, and conducting debriefing.
The nature of the respiratory therapy profession can be considered similar to anesthesiology. Both can be considered as hands-on specialties. In these specialties, the best way to master a competency, cognitive, skill, behavior, and attitude, is to practice it repeatedly.32 Thus, the most appropriate way to achieve this would be through more utilization of simulation. Simulation would enable learners to repeat the procedure as many as they need. However, it is common within the anesthesiology profession for simulation trainers to attend certain number of courses under supervision of expert trainers. This would help to enhance skills and recruit more novice trainers to be involved in simulation.32 Thus, several mini-workshops for faculty members with certification could increase utilization of simulation within respiratory therapy programs. It would help recruiting more faculty members to be involved in simulation. The faculty could maintain their certification with evidence of running at least one simulation course annually.
The current data show that majority of respiratory therapy programs lack sufficient knowledge about the healthcare simulation standards of best practice. Davis et al reported similar results. Only 28% of respiratory therapy programs in US are familiar with healthcare simulation standards.24 The authors suggested that familiarity of the best practice standards would enhance simulation practice and integration in the respiratory therapy academic programs. Also, our data show that 75% of the simulation laboratories/ centers are not accredited. It is known that the fundamental purposes of accreditation is to ensure high quality of the program and maintain this quality overtime. Accredited centers commonly maintain good structure, sufficient resources, and standardized practice.33
The limitations of the present investigation include the single time point of data collection. More details about barriers and challenges of SBL implementation would be useful. Also, it would be more appropriate to collect data from all respiratory therapy programs in Saudi Arabia. Nevertheless, we believe that the sample is sufficiently representative of respiratory therapy programs in Saudi Arabia.
Conclusion
The present data show that SBL is commonly utilized and relatively varied among respiratory therapy programs in Saudi Arabia. Overall, respiratory therapy programs have a good basis for SBL. However, a lack of formal training and a shortage of faculty were reported to be the major barriers for more SBL utilization.
