Reliability, validity, and responsiveness of a smartphone-based manikin to support pain self-reporting. Pain Rep 2024; 9:e1131. [PMID: 38375091 PMCID: PMC10876220 DOI: 10.1097/pr9.0000000000001131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 09/22/2023] [Accepted: 09/30/2023] [Indexed: 02/21/2024] Open
Abstract
Introduction Many people worldwide suffer from chronic pain. Improving our knowledge on chronic pain prevalence and management requires methods to collect pain self-reports in large populations. Smartphone-based tools could aid data collection by allowing people to use their own device, but the measurement properties of such tools are largely unknown. Objectives To assess the reliability, validity, and responsiveness of a smartphone-based manikin to support pain self-reporting. Methods We recruited people with fibromyalgia, rheumatoid arthritis, and/or osteoarthritis and access to a smartphone and the internet. Data collection included the Global Pain Scale at baseline and follow-up, and 30 daily pain drawings completed on a 2-dimensional, gender-neutral manikin. After deriving participants' pain extent from their manikin drawings, we evaluated convergent and discriminative validity, test-retest reliability, and responsiveness and assessed findings against internationally agreed criteria for good measurement properties. Results We recruited 131 people; 104 were included in the full sample, submitting 2185 unique pain drawings. Manikin-derived pain extent had excellent test-retest reliability (intraclass correlation coefficient, 0.94), moderate convergent validity (ρ, 0.46), and an ability to distinguish fibromyalgia and osteoarthritis from rheumatoid arthritis (F statistics, 30.41 and 14.36, respectively; P < 0.001). Responsiveness was poor (ρ, 0.2; P, 0.06) and did not meet the respective criterion for good measurement properties. Conclusion Our findings suggest that smartphone-based manikins can be a reliable and valid method for pain self-reporting, but that further research is warranted to explore, enhance, and confirm the ability of such manikins to detect a change in pain over time.

The efficacy of apneic oxygenation during intubation using a prototype of an oxygenation laryngoscope - a technical simulation. BMC Anesthesiol 2023; 23:273. [PMID: 37580678 PMCID: PMC10424410 DOI: 10.1186/s12871-023-02234-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 08/04/2023] [Indexed: 08/16/2023] Open
Abstract
BACKGROUND Recently, a non-commercial oxygenation laryngoscope was able to maintain apneic oxygenation during simulated intubation efforts. Since that prototype was 3 mm wider than a standard Macintosh laryngoscope blade, the intubation performance of this device may differ from standard blades. A new prototype of an oxygenation laryngoscope was developed, consisting of a standard-size Macintosh blade and a fixed oxygen supply line to the side. Actually, it is unclear at which point of this blade the oxygen supply line should end to facilitate the best possible oxygen supply for apneic oxygenation. METHODS In this simulation study using a standardized human airway manikin, the efficacy of apneic oxygenation by oxygen insufflation using standard and modified Macintosh blades was compared: a standard Macintosh blade without oxygen supply line as control, one with an additional oxygen supply line ending proximal near the handle, one with the line ending at the middle of the blade, and one with the line ending near the tip. A preoxygenated test lung was connected to an oximeter with a flow rate of 200ml/min, simulating oxygen consumption of a male adult, and to the trachea of an anatomically correctly shaped airway manikin. Apneic oxygenation was performed and oxygen content was measured over a 20-minutes observation period. Experiments were repeated five times for each laryngoscope blade. RESULTS Oxygen percentage in the test lung dropped from 100 ± 0% at the start of the experiment to 53 ± 1.5% in the room air control group (p < 0.001 compared to all other groups), and to 74 ± 2.5% in the proximal oxygen line group, whereas oxygen percentage remained at 100% in both the medium and distal oxygen line groups (p = 1 between these groups; p < 0.001 between all other groups). CONCLUSIONS In this simulation study with a preoxygenated airway manikin, the use of a modified Macintosh laryngoscope blade with oxygen line attached at the tip or at the middle were able to maintain apneic oxygenation without measurable drop of oxygen content over 20 min. Proximal placement of the oxygen supply line still showed an advantage against room air, however it did not completely prevent room air from entering the airway. TRIAL REGISTRATION Not applicable.

JOURNAL OF EDUCATIONAL EVALUATION FOR HEALTH PROFESSIONS 2023; 20:9. [PMID: 36997317 PMCID: PMC10129870 DOI: 10.3352/jeehp.2023.20.9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 03/19/2023] [Indexed: 06/19/2023]
Abstract
PURPOSE This study aimed to assess the effect of simulation teaching in critical care courses in a nursing study program on the quality of chest compressions of cardiopulmonary resuscitation (CPR). METHODS An observational cross-sectional study was conducted at the Faculty of Health Studies at the Technical University of Liberec. The success rate of CPR was tested in exams comparing 2 groups of students, totaling 66 different individuals, who completed half a year (group 1: intermediate exam with model simulation) or 1.5 years (group 2: final theoretical critical care exam with model simulation) of undergraduate nursing critical care education taught completely with a Laerdal SimMan 3G simulator. The quality of CPR was evaluated according to 4 components: compression depth, compression rate, time of correct frequency, and time of correct chest release. RESULTS Compression depth was significantly higher in group 2 than in group 1 (P=0.016). There were no significant differences in the compression rate (P=0.210), time of correct frequency (P=0.586), or time of correct chest release (P=0.514). CONCLUSION Nursing students who completed the final critical care exam showed an improvement in compression depth during CPR after 2 additional semesters of critical care teaching compared to those who completed the intermediate exam. The above results indicate that regularly scheduled CPR training is necessary during critical care education for nursing students.

THE JOURNAL OF CHIROPRACTIC EDUCATION 2022; 36:172-178. [PMID: 35914216 PMCID: PMC9536226 DOI: 10.7899/jce-21-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 03/24/2021] [Accepted: 12/13/2021] [Indexed: 06/15/2023]
Abstract
OBJECTIVE To assess the ability of 2nd-year students to identify normal and abnormal findings during cardiac and lung auscultation using high-fidelity manikin simulators and standardized patients. A secondary objective was to assess students' perceived competence and confidence in their abilities. METHODS This was a descriptive pilot study of randomly selected 2nd-year students at 1 chiropractic training program. Participants were asked to perform cardiac and lung auscultation on high-fidelity manikins (2 stations) and standardized human patients (2 stations) with normal and abnormal auscultation sounds. Participants described the auscultated sound as "abnormal" or "normal" and were also asked to score their confidence in describing the sound and competence in performing auscultation on a 100-mm visual analog scale. Descriptive statistics were calculated for all study variables. RESULTS Thirty-two students (23 women and 9 men) were included. For lung auscultation, 15.6% were incorrect on the human subject and 6.2% were incorrect on the manikin. For cardiac auscultation, 62.5% were incorrect on the human subject and 40.6% were incorrect on the manikin. Confidence mean scores ranged from 34.8 to 60. Competence mean scores ranged from 34.8 to 50. CONCLUSION Results identified that 2nd-year students from 1 institution were correct in identifying an abnormal sound during lung auscultation but reported low levels of perceived competence or confidence in their responses. They performed poorly on cardiac auscultation and reported low perceived confidence and competence in their abilities to perform cardiac auscultation and identify sounds.

Simulation-based training using a novel Surabaya hysterectomy mannequin following video demonstration to improve abdominal hysterectomy skills of obstetrics and gynecology residents during the COVID-19 pandemic in Indonesia: a pre- and post-intervention study. JOURNAL OF EDUCATIONAL EVALUATION FOR HEALTH PROFESSIONS 2022; 19:11. [PMID: 35614019 PMCID: PMC9149772 DOI: 10.3352/jeehp.2022.19.11] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Accepted: 04/26/2022] [Indexed: 06/15/2023]
Abstract
PURPOSE During the coronavirus disease 2019 (COVID-19) pandemic, the number of abdominal hysterectomy procedures decreased in Indonesia. The existing commercial abdominal hysterectomy simulation model is expensive and difficult to reuse. This study compared residents' abdominal hysterectomy skills after simulation-based training using the Surabaya hysterectomy mannequin following a video demonstration. METHODS We randomized 3rd- and 4th-year obstetrics and gynecology residents to a video-based group (group 1), a simulation-based group (group 2), and a combination group (group 3). Abdominal hysterectomy skills were compared between before and after the educational intervention. The pre- and post-tests were scored by blinded experts using the validated Objective Structured Assessment of Technical Skills (OSATS) and Global Rating Scale (GRS). RESULTS A total of 33 residents were included in the pre- and post-tests. The OSATS and GRS mean differences after the intervention were higher in group 3 than in groups 1 and 2 (OSATS: 4.64 [95% CI, 2.90-6.37] vs. 2.55 [95% CI, 2.19-2.90] vs. 3.82 [95% CI, 2.41-5.22], P=0.047; GRS: 10.00 [95% CI, 7.01-12.99] vs. 5.18 [95% CI, 3.99-6.38] vs. 7.18 [95% CI, 6.11-8.26], P=0.006). The 3rd-year residents in group 3 had greater mean differences in OSATS and GRS scores than the 4th-year residents (OSATS: 5.67 [95% CI, 2.88-8.46]; GRS: 12.83 [95% CI, 8.61-17.05] vs. OSATS: 3.40 [95% CI, 0.83-5.97]; GRS: 5.67 [95% CI, 2.80-8.54]). CONCLUSION Simulation-based training using the Surabaya hysterectomy mannequin following video demonstration can be a bridge to learning about abdominal hysterectomy for residents who had less surgical experience during the COVID-19 pandemic.

JOURNAL OF EDUCATIONAL EVALUATION FOR HEALTH PROFESSIONS 2022; 19:4. [PMID: 35157793 PMCID: PMC8942784 DOI: 10.3352/jeehp.2022.19.4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Accepted: 02/14/2022] [Indexed: 06/14/2023]
Abstract
PURPOSE Obstetric anal sphincter injury (OASI) is one of the most common complication during delivery. Simulation models using manikin can be used as an effective medical learning method to improve students' abilities before meeting patients. It aimed to describe the development of anal sphincter injury model and assess the resident satisfaction and self-confidence after perineal repair workshop with anal sphincter injury simulator in Indonesia. METHODS This was cross-sectional study with evaluation of outcome before and after workshop. We created silicone-latex simulation anal sphincter injury model. Then, we validated this simulation and made it as simulation model for workshop. We asked residents' satisfaction repairing anal sphincter injury using simulation model and residents' self-confidence when practicing the anal sphincter injury repair. RESULTS All residents felt the simulation-based workshop was valuable (100%). Most of score for similarity simulation model were good (about 8). The self-assessment of confidence was measured prior to the workshop and after the workshop. The overall self-confidence was increased significantly after workshop in procedure identification external sphincter ani (EAS) (P=0.031), suturing anal mucosa (P=0.001), suturing internal sphincter ani (P=0.001), suturing external sphincter ani (EAS) (P <0.001), evaluation of sphincter ani tone (P=0.016). CONCLUSION Anal sphincter injury simulator improves the self-confidence of residents in procedure identification external sphincter ani (EAS), suturing anal mucosa, suturing internal sphincter ani, suturing external sphincter ani (EAS) and evaluation of sphincter ani tone.

Abstract
COVID-19 pandemic has created a lot of turmoil in medical teaching, the magnitude of impact is many folds in the subject of anatomy, as it is practical based. A major challenge for anatomy teachers is to replicate the experience of practical exposures. These exposures range from cadaveric dissection to demonstration of bones, museum specimens, and histology slides, where they will have interactive communication with students, and thus help in the enhancement of communication and clinical skills among them. In recent days, anatomy teachers throughout the globe started using various advanced technology to make the teaching-learning session more interesting. In pre-pandemic era, usage of such advancements in information and communication technology was a 'choice'. But pandemic has changed the situation drastically, what was a 'choice' earlier is now an 'obligation.' Presently although infection rate is low, vaccination rate is high, most of the medical schools re-opened for usual offline teaching, still body donation is all time low making the situation 'back to square one'. Keeping such unprecedented situations in mind, we need to incorporate various innovative educational technologies in day-to-day teaching-learning methodologies.

Transfer of learning from simulated setting to the clinical setting: identifying instructional design features. Med J Islam Repub Iran 2021; 35:90. [PMID: 34291014 PMCID: PMC8285558 DOI: 10.47176/mjiri.35.90] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Indexed: 01/22/2023] Open
Abstract
Background: Transfer of learning (ToL) is the endpoint of simulation-based training (SBT). It is affected by numerous factors, which can be classified into 3 categories: learner characteristics, work environment, and training design. The first 2 have been identified to some extent in previous research. In this study, the aim was to identify the instructional design (ID) features affecting the ToL in SBT. Methods: This qualitative study was conducted in 2 phases. Phase 1 covers thematic analysis of comparative studies in the field of SBT. A systematic search was performed on 6 databases of Ovid MEDLINE, EMBASE, PsycINFO, CENTRAL, Scopus, and Web of Science, and the references of related systematic reviews were also checked. In phase 2, semi-structured interviews were conducted with key informants (instructors and learners) and analyzed using directed content analysis. The results of the 2 phases were combined, and finally ID features of SBT were identified and categorized. Results: In the first phase, 121 comparative studies were reviewed and in the second phase, 17 key informants were interviewed. After combining the results of the phases, the ID features affecting the ToL in SBT were classified into 3 broad categories and 15 subcategories as follows: (1) presimulation: preparation, briefing, and teaching cognitive base; (2) underlying theories: deliberate practice, mastery learning, and proficiency-based training; (3) and methods and techniques: distributed practice, variability, increasing complexity, opportunity for practice, repetitive practice, active learning, feedback/debriefing, simulator type, and simulator fidelity. Conclusion: Although learning is transferred from the simulated setting to the clinical setting, this process is not automatic and straightforward. Numerous factors affect this transfer. The results of this research can be used in designing and evaluating the SBT programs.

Comparison of the use of manikins and simulated patients in a multidisciplinary in situ medical simulation program for healthcare professionals in the United Kingdom. JOURNAL OF EDUCATIONAL EVALUATION FOR HEALTH PROFESSIONS 2021; 18:8. [PMID: 33873264 PMCID: PMC8175761 DOI: 10.3352/jeehp.2021.18.8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Accepted: 04/07/2021] [Indexed: 06/12/2023]
Abstract
PURPOSE Simulation training is increasingly popular in healthcare education, and often relies on specially designed manikins. However, it is also possible to work with actors, or simulated patients (SPs), which may provide a greater sense of realism. This study aimed to compare these 2 approaches, to ascertain which makes healthcare professionals feel most comfortable, which leads to the greatest improvement in confidence, and which is most beneficial to learning. METHODS This study was embedded in a pre-existing multidisciplinary in situ simulation program. A multidisciplinary group of learners from a range of backgrounds—including nurses, doctors, and other allied health professionals—were asked to complete a questionnaire about their learning preferences. We collected 204 responses from 40 simulation sessions over 4 months, from September to December 2019. Of these 204 responses, 123 described using an SP and 81 described using a manikin. RESULTS We found that 58% of respondents believed they would feel more comfortable working with an actor, while 17% would feel more comfortable using a manikin. Learners who used both modalities reported a significant increase in confidence (P<0.0001 for both). Participants felt that both modalities were beneficial to learning, but SPs provided significantly more benefits to learning than manikins (P<0.0001). The most common reason favoring SP-based simulation was the greater realism. CONCLUSION In scenarios that could reasonably be provided using either modality, we suggest that educators should give greater consideration to using SP-based simulation.

The role of manikins in nursing students' learning: A systematic review and thematic metasynthesis. NURSE EDUCATION TODAY 2021; 98:104661. [PMID: 33298327 DOI: 10.1016/j.nedt.2020.104661] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 10/16/2020] [Accepted: 11/03/2020] [Indexed: 06/12/2023]
Abstract
OBJECTIVES To summarise and synthesise findings from qualitative primary research studies of nursing students' experiences from educational activities using manikins to gain a deeper understanding of the role these manikins play in the students' learning. DESIGN AND DATA SOURCES A systematic review and thematic metasynthesis were conducted. Cinahl+, Ovid Medline, ERIC and Embase were searched systematically. REVIEW METHODS Sandelowski and Barroso's framework guided the review process. A comprehensive search to identify qualitative studies of nursing students' experiences from learning with manikins was performed in January 2019 and updated in April 2020. Study selection was guided by six screening questions derived from these inclusion criteria: qualitative primary studies, published from 2008, in English or Scandinavian, presenting findings of undergraduate nursing students' experiences with manikins at all fidelity levels. Thomas and Harden's method for thematic synthesis was followed. RESULTS Twenty-eight articles of twenty-seven studies were included. We identified three synthesised analytic themes: Seeing the manikin as a doll or a patient, Experiencing yourself as a nurse caring for a patient, and Being a team member. CONCLUSIONS When it is perceived as a patient, a manikin can give students a realistic experience of what it means to behave like nurses. Consequently, this realism lets students practice and acquire relational, communicative, and collaborative nursing skills. Using a manikin can facilitate the development of students' professional identity.

Abstract
INTRODUCTION Charging defibrillators prior to analyzing heart rhythms may decrease the no-flow time during rhythm check pauses while resuscitating in cardiac arrest. Although this anticipatory method is already used in some centers little is known about its safety. This study was carried out to confirm the safety and feasibility of the anticipatory method. It was hypothesized that this anticipatory method results in shorter total no-flow times, while other parameters of defibrillation efficacy including defibrillator safety and minimization of peri-shock pauses are unchanged. METHODS This manikin study assigned 243 medical students randomly to study groups, 121 to the anticipatory method and 122 to the recommended European Resuscitation Council (ERC) algorithm. Of these 237 students ultimately underwent training (112 anticipatory method vs. 125 ERC algorithm). Participants were assessed and video recorded during a simulated cardiac arrest scenario which included three different heart rhythms (ventricular fibrillation [VF], pulseless ventricular tachycardia [pVT], asystole) in randomized order. Video and software analyses were performed. Defibrillation safety was assessed using a 17-item checklist defined beforehand. RESULTS A total of 203 simulated cardiac arrests (75 anticipatory method and 128 ERC 2010 algorithm) were analyzed. The anticipatory method did not significantly reduce no-flow time (25.8 s, standard deviation, SD 7.4 s vs. 27.4 s SD 8.4 s, p = 0.19); however, peri-shock pauses were significantly longer in the anticipatory group compared to the ERC 2010 group (9.5 s SD 2.8 s vs. 3.3 s SD 1.9 s, p < 0.001). No significant difference concerning defibrillation safety between the groups was observed according to the 17-item checklist (14.6 SD 1.6 vs. 15.0 SD 1.4, p = 0.07). CONCLUSION Charging defibrillators before rhythm analysis did not decrease total no-flow time in simulated cardiac arrests but resulted in significantly longer peri-shock pauses exceeding 5 s. No significant differences in defibrillation safety were observed between the groups.

Abstract
Endotracheal intubation (EI) is a potentially lifesaving but high-risk procedure in critically ill patients. While the ACGME mandates that trainees in pulmonary and critical care medicine (PCCM) achieve competence in this procedure, there is wide variation in EI training across the USA. One study suggests that 40% of the US PCCM trainees feel they would not be proficient in EI upon graduation. This article presents a review of the EI training literature; the recommendations of a national group of PCCM, anesthesiology, emergency medicine, and pediatric experts; and a call for further research, collaboration, and consensus guidelines.

Long-term benefits of chest compression-only cardiopulmonary resuscitation training using real-time visual feedback manikins: a randomized simulation study. Clin Exp Emerg Med 2020; 7:206-212. [PMID: 33028064 PMCID: PMC7550815 DOI: 10.15441/ceem.20.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 05/14/2020] [Indexed: 12/03/2022] Open
Abstract
Objective Cardiopulmonary resuscitation (CPR) education with a feedback device is known to result in better CPR skills compared to one without the feedback device. However, its long-term benefits have not been established. The purpose of this study was to evaluate the long-term CPR skill retention after training using real-time visual manikins in comparison to that of non-feedback manikins. Methods We recruited 120 general university students who were randomly divided into the real-time feedback group (RTFG) and the non-feedback group. Of them, 95 (RTFG, 48; non-feedback group, 47) attended basic life support and automated external defibrillation training for 1 hour. For comparison of retention of CPR skills, the two groups were evaluated based on 2-minute chest compression performed immediately after training and at 3, 6, and 9 months. The CPR parameters between the two groups were also compared using a generalized linear model. Results At immediately after training, the performance of RTFG was better in terms of average chest compression depth (51.9±1.1 vs. 45.5±1.1, p<0.001) and a higher percentage of adequate chest compression depth (51.0±4.1 vs. 26.9±4.2, p<0.001). This significant difference was maintained until 6 months after training, but there was no difference at 9 months after training. However, there was no significant difference in the chest compression rate and the correct hand position at any time point. Conclusion CPR training with a real-time visual feedback manikin improved skill acquisition in chest compression depth, but only until 6 months after the training. It could be a more effective educational method for basic life support training in laypersons.

Considerations in training student pharmacists to perform physical assessment. CURRENTS IN PHARMACY TEACHING & LEARNING 2020; 12:577-584. [PMID: 32336456 DOI: 10.1016/j.cptl.2020.01.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2019] [Revised: 11/06/2019] [Accepted: 01/11/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND AND PURPOSE Patient assessment skills are an integral component of pharmacy education. Fostering a realistic learning experience requires simulated interaction with standardized patients (SPs). Cost, student performance, and student preference are important factors to consider when selecting a SP option. The study objective was to compare student peer SPs (SPSPs) and manikins for training student pharmacists to perform physical assessment skills. EDUCATIONAL ACTIVITY AND SETTING First-year student pharmacists were taught five physical assessment techniques and practiced on both a manikin and SPSPs. An examination was administered to assess student knowledge and technique performance. Student preference was assessed via survey. A cost utility analysis compared the costs of a SimMan manikin with SPSPs. FINDINGS All enrolled student pharmacists met competency during the final exam. Students strongly agreed or agreed: practicing on a live simulated patient enhanced my ability to perform physical assessment skills (95%); practicing on SimMan enhanced my ability to perform physical assessment skills (88%); I am interested in incorporating physical assessments in my future pharmacy (88%); and I believe future practice will support implementing physical assessments (85%). The cost utility analysis determined a utility of 4.74 with student peer SPs and 4.49 with SimMan. SUMMARY Student pharmacists were successfully trained to perform physical assessment techniques utilizing both SPSPs and a manikin. Understanding differences in instructional methods allows educators to determine best practices when teaching physical assessment.

Comparative evaluation of Airtraq™ and GlideScope® videolaryngoscopes for difficult pediatric intubation in a Pierre Robin manikin. Eur J Pediatr 2019; 178:1105-1111. [PMID: 31119438 DOI: 10.1007/s00431-019-03396-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 04/27/2019] [Accepted: 04/30/2019] [Indexed: 11/25/2022]
Abstract
Airway management in children is associated with anatomical and physiological challenges compared with adults. Pierre Robin sequence (PRS) is a condition characterized by micrognathia, glossoptosis, and cleft palate and related to a difficult airway. Both the Airtraq™ and GlideScope® have never been previously directly compared in PRS. Our aim was to evaluate the performance of these two airway devices in a PRS manikin for ethical and practical reasons. Between April and July 2017, 26, pediatric intensive care clinical fellows or trainees from a tertiary pediatric center were recruited to participate. In this prospective and randomized crossover trial, all participants first set up the Airtraq™ and the GlideScope® and then used these videolaryngoscopes to intubate an AirSim® PRS manikin. Our primary outcome measure was the duration of the successful intubation attempt. Duration of the successful intubation attempt was 18.1 (14.2-34.9 [10.2-51.3]) s for the Airtraq™ compared to 31.1 (18.7-55.6 [6.2-119]) s for the GlideScope® (p = 0.045). Setup time was 50.0 ± 6.9 s for the Airtraq™ and 27.8 ± 8.6 s for the GlideScope® (p < 0.001).Conclusion: Even though setup time was longer, the characteristics of intubation performance were superior with the Airtraq™ relative to the GlideScope® in an AirSim® PRS manikin. What is Known: • Several case reports have described the successful use of Airtraq™ to intubate children with Pierre Robin sequence. • The GlideScope® has demonstrated similar rates of first-attempt successful intubation to flexible fiberoptic bronchoscopy in a Pierre Robin sequence manikin. What is New: • In the hands of pediatric non-airway specialists, the characteristics of intubation performance, including the duration of the successful intubation attempt, are superior with the Airtraq™ compared with the GlideScope® in a Pierre Robin sequence manikin. • Setup time for the Airtraq™ is, however, longer relative to that for the GlideScope®.

Abstract
Introduction Our current medical curriculum devotes a large percentage of time to knowledge acquisition by means of didactic lectures. Psychomotor skill acquisition takes a back seat. Certain lifesaving skills like basic life support skill training have not even made an appearance in the current curriculum. Equal time distribution to cognitive and psychomotor skills should be allotted for MBBS trainees, which is a very practical subject. Simulation can prove to be a valuable tool in imparting skill training. The present study aims to evaluate the efficacy of different teaching modalities in imparting lifesaving skills among first-year MBBS students. Materials and methods This cross-sectional study was conducted among 33 first-year students who consented to participate. Approval was obtained from the institutional ethics committee. The students were divided into three groups, each undergoing either didactic lecture or animation-based videos or simulation studies. Pretest, posttest, and skills tests were administered to them. One-way analysis of variance (ANOVA) and paired t test were the statistical tests employed using SPSS version 21. Results The pretest and posttest scores were comparable in the three groups while the improvement in the posttest scores in all the three groups was significant. The skills test was significantly better in the group undergoing simulation training compared to the other groups. Conclusion Didactic, animation, and simulation are all good methods in imparting cognitive knowledge, but simulation is the method of choice in imparting psychomotor skills. Clinical significance An overhauling of the medical curriculum to include more skills training to the budding doctors using simulation-based techniques is recommended.

Abstract
OBJECTIVES The aim of this study was to compare the intubating laryngeal mask (iLM) airway and the new intubating laryngeal tube (iLTS-D) in use by residents with minimal previous intubation experience during simulated conditions of reduced cervical spine mobility. MATERIAL AND METHODS Thirty first-year residents in anesthesiology participated in the study (18 women). All participants had minimal intubation experience (fewer than 10 previously performed intubations) and were novices in the specialty. Both devices were used by each participant after random assignment of order. We recorded the time required to insert the device and start to ventilate through it (T1) and the time from insertion and intubation to successful ventilation (T2). Efficacy of intubation and each resident's assessment of ease of use were also assessed.Observational study using biomechanical inertial sensors to detect movement in the spinal column during removal of helmets. RESULTS The residents' mean (SD) T1 values were similar for the 2 devices (iLMA, 15.3 [5.5] seconds; iLTS-D, 15.4 [5.5] seconds; P=.938). T2 was shorter with the iLTS-D (25.4 [8.6] seconds vs 31.9 [8.8] seconds with the iLMA; P=.005). There were no failed intubation attempts with the iLTS-D. CONCLUSION The new iLTS-D may be a good alternative to the iLMA because a patient can be intubated and successfully ventilated in less time. The rate of successful intubation is also better with the iLTS-D.

Abstract
None of the previous studies localized pain in comparison with graphic scheme. Our aim was to investigate the validity of direct questioning about the main pain localization in comparison with schematic evaluation. In this cross-sectional study, 331 patients, mean age 49.4±10.72 years, localized their main pain site anatomically with manikin and by direct questioning. Two methods were employed to localize pain: direct questioning and schematic evaluation (manikin). Sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), negative likelihood ratio (NLR) and odds ratio (OR) were used to compare these two methods. Study patients answered in both methods. The sensitivity and PPV were mostly in a weak range, while accuracy, specificity and NPV were mostly in good range. Kappa index was in the marginal reproducibility range. Pain in the left part of the body had a higher OR (OR=9). PLR for pain in the right part of the body was 28.03. NLR for all questions was located in the small and rarely important change probability group. Negative answer in direct questioning was more reliable than a positive one. Pain localization in the left side of the body was more reliable.

Abstract
OBJECTIVES The quality of telephone-assisted cardiopulmonary resuscitation (CPR) needs improvement. This study investigates whether a dispatchers' perception is an adequate measure of the actual quality of CPR provided by laypersons. MATERIAL AND METHODS Individual participant data from 3 randomized simulation trials, with identical methodology but different interventions, were combined for this analysis. Professional dispatchers gave telephone assistance to laypersons, who each provided 10 minutes of CPR on a manikin. Dispatchers were requested to classify the quality of providers' CPR as adequate or inadequate. Based on actual readings from manikins we classified providers' performance as adequate at 5-6 cm for depth and 100-120 compressions per minute (cpm) for rate. We calculated metrics of dispatcher accuracy. RESULTS Six dispatchers rated the performance of 94 laypersons (38 women [42%]) with a mean (SD) age of 37 (14) years. In 905 analyzed minutes of telephone-assisted CPR, the mean compression depth and rate was 41 (13) mm and 98 (24) cpm, respectively. Analysis of dispatchers' diagnostic test accuracy for adequate compression depth yielded a sensitivity of 65% (95 CI 36%-95%) and specificity of 42% (95% CI, 32%-53%). Analysis of their assessment of adequate compression rate yielded a sensitivity of 75% (95% CI, 64%-86%) and specificity of 42% (95% CI, 32%-52%). Although dispatchers always underestimated the actual values of CPR parameters, the female dispatchers evaluations were less inaccurate than the evaluations of make dispatchers; the dispatchers overall (males and females together) underestimated the adequacy of female laypersons' CPR performance to a greater degree than female dispatchers did. CONCLUSION The ability of dispatchers to estimate the quality of telephone-assisted CPR is limited. Dispatchers estimates of CPR adequacy needs to be studied further in order to find ways that telephone-assisted CPR might be improved.

Comparison between an instructor-led course and training using a voice advisory manikin in initial cardiopulmonary resuscitation skill acquisition. Clin Exp Emerg Med 2016; 3:158-164. [PMID: 27752634 PMCID: PMC5065339 DOI: 10.15441/ceem.15.114] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2016] [Revised: 05/17/2016] [Accepted: 05/23/2016] [Indexed: 12/04/2022] Open
Abstract
Objective We compared training using a voice advisory manikin (VAM) with an instructor-led (IL) course in terms of acquisition of initial cardiopulmonary resuscitation (CPR) skills, as defined by the 2010 resuscitation guidelines. Methods This study was a randomized, controlled, blinded, parallel-group trial. We recruited 82 first-year emergency medical technician students and distributed them randomly into two groups: the IL group (n=41) and the VAM group (n=37). In the IL-group, participants were trained in “single-rescuer, adult CPR” according to the American Heart Association’s Basic Life Support course for healthcare providers. In the VAM group, all subjects received a 20-minute lesson about CPR. After the lesson, each student trained individually with the VAM for 1 hour, receiving real-time feedback. After the training, all subjects were evaluated as they performed basic CPR (30 compressions, 2 ventilations) for 4 minutes. Results The proportion of participants with a mean compression depth ≥50 mm was 34.1% in the IL group and 27.0% in the VAM group, and the proportion with a mean compression depth ≥40 mm had increased significantly in both groups compared with ≥50 mm (IL group, 82.9%; VAM group, 86.5%). However, no significant differences were detected between the groups in this regard. The proportion of ventilations of the appropriate volume was relatively low in both groups (IL group, 26.4%; VAM group, 12.5%; P=0.396). Conclusion Both methods, the IL training using a practice-while-watching video and the VAM training, facilitated initial CPR skill acquisition, especially in terms of correct chest compression.

A brief simulation intervention increasing basic science and clinical knowledge. MEDICAL EDUCATION ONLINE 2016; 21:30744. [PMID: 27060102 PMCID: PMC4826461 DOI: 10.3402/meo.v21.30744] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2015] [Revised: 03/10/2016] [Accepted: 03/17/2016] [Indexed: 06/01/2023]
Abstract
BACKGROUND The United States Medical Licensing Examination (USMLE) is increasing clinical content on the Step 1 exam; thus, inclusion of clinical applications within the basic science curriculum is crucial. Including simulation activities during basic science years bridges the knowledge gap between basic science content and clinical application. PURPOSE To evaluate the effects of a one-off, 1-hour cardiovascular simulation intervention on a summative assessment after adjusting for relevant demographic and academic predictors. METHODS This study was a non-randomized study using historical controls to evaluate curricular change. The control group received lecture (n l=515) and the intervention group received lecture plus a simulation exercise (n l+s=1,066). Assessment included summative exam questions (n=4) that were scored as pass/fail (≥75%). USMLE-style assessment questions were identical for both cohorts. Descriptive statistics for variables are presented and odds of passage calculated using logistic regression. RESULTS Undergraduate grade point ratio, MCAT-BS, MCAT-PS, age, attendance at an academic review program, and gender were significant predictors of summative exam passage. Students receiving the intervention were significantly more likely to pass the summative exam than students receiving lecture only (P=0.0003). DISCUSSION Simulation plus lecture increases short-term understanding as tested by a written exam. A longitudinal study is needed to assess the effect of a brief simulation intervention on long-term retention of clinical concepts in a basic science curriculum.

Comparison of Miller and Airtraq laryngoscopes for orotracheal intubation by physicians wearing CBRN protective equipment during infant resuscitation: a randomized crossover simulation study. Scand J Trauma Resusc Emerg Med 2016; 24:35. [PMID: 27004945 PMCID: PMC4804507 DOI: 10.1186/s13049-016-0228-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2015] [Accepted: 03/15/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The purpose of this study was to evaluate the performance of orotracheal intubation with the Miller laryngoscope compared with the Airtraq laryngoscope by emergency and pediatric physicians wearing CBRN-PPE type III on infant manikins with conventional airway. We hypothesized that in this situation, the orotracheal intubation with the Airtraq laryngoscope would be faster and more effective than with the Miller laryngoscope. METHODS This was a prospective, randomized, crossover, single-center study who recruited emergency department physicians on a voluntary basis. Each physician performed a total of 20 intubation trials while in CBRN-PPE with the two intubation techniques, Miller and Airtraq. Intubations by each airway device were tested over ten consecutive runs. The order of use of one or the other devices was randomized with a ratio of 1:1. The primary endpoint was overall orotracheal intubation success. RESULTS Fifty-five emergency and pediatric physicians were assessed for eligibility. Forty-one physicians were included in this study and 820 orotracheal intubation attempts were performed. The orotracheal intubation success rate with the Airtraq laryngoscope was higher than with the Miller (99% vs. 92%; p-adjusted <.001). The orotracheal intubation and glottis visualization times decreased with the number of attempts (p <.001). The median orotracheal intubation time with the Airtraq laryngoscope was lower than with the Miller laryngoscope (15 s vs. 20 s; p-adjusted <.001). The median glottis visualization time with the Airtraq laryngoscope and with the Miller laryngoscope were not different (6.0 s vs. 7.5 s; p-adjusted =.237). Thirty-four (83 %) physicians preferred the Airtraq laryngoscope versus 6 (15 %) for the Miller (p-adjusted <.001). DISCUSSION For tracheal intubation by physicians wearing CBRN-PPE during infant resuscitation simulation, we showed that the orotracheal intubation success rate with the Airtraq laryngoscope was higher than with the Miller laryngoscope and that orotracheal intubation time with the Airtraq laryngoscope was lower than with the Miller laryngoscope. CONCLUSIONS It seems useful to train the physicians in emergency departments in the use of pediatric Airtraq and for the management of CBRN risks.

Abstract
BACKGROUND Simulation allows students to practice key psychomotor skills and gain technical proficiency, fostering the development of clinical reasoning and student confidence in a low risk environment. Manikins are a valuable learning tool; yet there is a distinct lack of empirical research investigating how to enhance engagement between nursing students and manikins. OBJECTIVE To describe student perspectives of a layered, technology enhanced approach to improve the simulation learning experience. EDUCATIONAL FRAMEWORK Tanner's Model of Clinical Judgment underpins the entire curriculum. This study additionally drew on the principles of narrative pedagogy. INTERVENTION Across ten teaching weeks, five separate case studies were introduced to students through short vignettes. Students viewed the vignettes prior to their laboratory class. In the labs, manikins were dressed in the props used in the vignettes. SETTING The innovation was trialed in a second year core subject of a Bachelor of Nursing program in a large urban university in the autumn semester of 2014. DATA COLLECTION AND ANALYSIS Following ethics approval, students were emailed a participant information sheet. A focus group of nine students was held. The discussion was digitally recorded and transcribed verbatim prior to being subject to thematic analysis. Students' comments (143) about the vignettes in their standard subject specific student feedback surveys were also considered as data. RESULTS Four themes were identified: Getting past the plastic; knowing what to say; connecting and caring; and, embracing diversity. The feedback indicated that these measures increased students ability to suspend disbelief, feel connected to, and approach the manikins in a more understanding and empathetic fashion. CONCLUSIONS In addition to achieving increased engagement with manikins, other advantages such as students reflecting on their own values and pre-conceived notions of people from diverse backgrounds were realized.

[Educational suitability of endotracheal intubation using a video-laryngoscope]. KOREAN JOURNAL OF MEDICAL EDUCATION 2015; 27:267-274. [PMID: 26657548 PMCID: PMC8814511 DOI: 10.3946/kjme.2015.27.4.267] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/17/2015] [Revised: 09/06/2015] [Accepted: 09/07/2015] [Indexed: 06/05/2023]
Abstract
PURPOSE The purpose of this study is to determine the educational suitability of the video-laryngoscope in teaching endotracheal intubation to students. METHODS Medical students participated in a course on the use of a Macintosh direct laryngoscope and McGrath MAC videolaryngoscope for intubation. The course comprised a 1-hour lecture and 30 minutes of practice on a manikin. After the course, in each of the three simulated patient scenarios-normal airway, cervical spine fixation, and tongue edema-time to intubate, success rate, and chance of complications were measured. A questionnaire was administered before and after the course to determine thesuitability of intubation by video-laryngoscope for a medical education course. Also, changes in the perception and stance on the video-laryngoscope were evaluated. RESULTS Time to intubate decreased as attempts were repeated. The first-attempt success rate in the cervical spine fixation scenario was higher using the video-laryngoscope (p=0.028). Rates if tooth injury were lower in the cervical spine fixation (p=0.005) andtongue edema scenarios (p=0.021) using the video-laryngoscope. Based on the questionnaires, students responded positively with regard to their knowledge of the video-laryngoscope, its practical value, and its suitability for medical education (p<0.001). Also,the preference for the video-laryngoscope was greater (p=0.044). Students felt that repeated attempts and feedback on intubation were helpful. CONCLUSION The students' evaluations and surveys showed positive results to intubation by video-laryngoscope. Thus, based on its suitability for medical education it is reasonable to consider learning intubation using the video-laryngoscope.

Differences in Hands-off Time According to the Position of a Second Rescuer When Switching Compression in Pre-hospital Cardiopulmonary Resuscitation Provided by Two Bystanders: A Randomized, Controlled, Parallel Study. J Korean Med Sci 2015; 30:1347-53. [PMID: 26339178 PMCID: PMC4553685 DOI: 10.3346/jkms.2015.30.9.1347] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2014] [Accepted: 05/22/2015] [Indexed: 11/20/2022] Open
Abstract
The change of compressing personnel will inevitably accompany hands off time when cardiopulmonary resuscitation (CPR) is performed by two or more rescuers. The present study assessed whether changing compression by a second rescuer located on the opposite side (OS) of the first rescuer can reduce hands-off time compared to CPR on the same side (SS) when CPR is performed by two rescuers. The scenario of this randomized, controlled, parallel simulation study was compression-only CPR by two laypersons in a pre-hospital situation. Considering sex ratio, 64 participants were matched up in 32 teams equally divided into two gender groups, i.e. , homogenous or heterogeneous. Each team was finally allocated to one of two study groups according to the position of changing compression (SS or OS). Every team performed chest compression for 8 min and 10 sec, with chest compression changed every 2 min. The primary endpoint was cumulative hands-off time. Cumulative hands-off time of the SS group was about 2 sec longer than the OS group, and was significant (6.6 ± 2.6 sec vs. 4.5 ± 1.5 sec, P = 0.005). The range of hands off time of the SS group was wider than for the OS group. The mean hands-off times of each rescuer turn significantly shortened with increasing number of turns (P = 0.005). A subgroup analysis in which cumulative hands-off time was divided into three subgroups in 5-sec intervals revealed that about 70% of the SS group was included in subgroups with delayed hands-off time ≥ 5 sec, with only 25% of the OS group included in these subgroups (P = 0.033). Changing compression at the OS of each rescuer reduced hands-off time compared to the SS in prehospital hands-only CPR provided by two bystanders.

A vertical two-thumb technique is superior to the two-thumb encircling technique for infant cardiopulmonary resuscitation. Acta Paediatr 2015; 104:e70-5. [PMID: 25382371 DOI: 10.1111/apa.12857] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2014] [Revised: 09/03/2014] [Accepted: 11/04/2014] [Indexed: 11/27/2022]
Abstract
AIM The two-thumb encircling (TTE) technique often results in suboptimal cardiac compression and does not meet the requirements of current resuscitation guidelines. We compared this technique with the vertical two-thumb (VTT) technique, our novel modification of the TTE technique. METHODS This was a prospective randomised crossover simulation study of out-of-hospital infant cardiopulmonary resuscitation (CPR). Participants who had completed a basic life support course performed 10 cycles of cardiac compressions on a manikin for each technique. RESULTS We enrolled 36 medical doctors who had applied for a hospital internship in this study. The VTT generated significantly higher pressure than the TTE and the pressure difference ranged from 26.8 to 62.9 mmHg for each cycle, with a mean difference of 43.5 mmHg (95% CI, 37.8-49.2). The difference in pressure showed a tendency to increase with increasing cycles of cardiac compressions. The participants' heart and respiratory rate was higher with the VTT, but they said that it was easier to perform cardiac compressions with this technique. CONCLUSION The VTT technique generated more pressure than the TTE technique in a simulated model of infant out-of-hospital CPR. It can provide an alternative compression technique for effective infant CPR, especially for the rescuers with small hands or a weak grip.

Factors affecting the accuracy of chest compression depth estimation. Clin Exp Emerg Med 2014; 1:101-108. [PMID: 27752560 PMCID: PMC5052833 DOI: 10.15441/ceem.14.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2014] [Revised: 07/25/2014] [Accepted: 07/29/2014] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE We aimed to estimate the accuracy of visual estimation of chest compression depth and identify potential factors affecting accuracy. METHODS This simulation study used a basic life support mannequin, the Ambu man. We recorded chest compression with 7 different depths from 1 to 7 cm. Each video clip was recorded for a cycle of compression. Three different viewpoints were used to record the video. After filming, 25 clips were randomly selected. Health care providers in an emergency department were asked to estimate the depth of compressions while watching the selected video clips. Examiner determinants such as experience and cardiopulmonary resuscitation training and environment determinants such as the location of the camera (examiner) were collected and analyzed. An estimated depth was considered correct if it was consistent with the one recorded. A multivariate analysis predicting the accuracy of compression depth estimation was performed. RESULTS Overall, 103 subjects were enrolled in the study; 42 (40.8%) were physicians, 56 (54.4%) nurses, and 5 (4.8%) emergency medical technicians. The mean accuracy was 0.89 (standard deviation, 0.76). Among examiner determinants, only subjects' occupation and clinical experience showed significant association with outcome (P=0.03 and P=0.08, respectively). All environmental determinants showed significant association with the outcome (all P<0.001). Multivariate analysis showed that accuracy rate was significantly associated with occupation, camera position, and compression depth. CONCLUSIONS The accuracy rate of chest compression depth estimation was 0.89 and was significantly related with examiner's occupation, camera view position, and compression depth.

Observed improvements in an intern's ability to initiate critical emergency skills in different cardiac arrest scenarios using high-fidelity simulation. THE JOURNAL OF CHIROPRACTIC EDUCATION 2014; 28:164-167. [PMID: 24837883 PMCID: PMC4211590 DOI: 10.7899/jce-13-33] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2013] [Revised: 12/12/2013] [Accepted: 01/24/2014] [Indexed: 06/03/2023]
Abstract
Objective : The objective of this study was to report observed changes in an intern's ability to initiate critical emergency skills in different cardiac arrest scenarios with high-fidelity simulation over a 10-month period. Methods : One intern's performance was retrospectively analyzed using video recordings of 4 simulations at different stages in the training program. The key outcome was the duration of time expired for 4 critical skills, including activating the emergency response system, initiating cardiopulmonary resuscitation (CPR), using an automated external defibrillator (AED), and passively administrating oxygen. Results : The intern became more efficient in each subsequent simulation for activating the emergency response system and initiating CPR. The time to use the AED stayed relatively constant. The administration of oxygen was inconsistent. Conclusion : An improvement in the speed of applying emergency critical skills was observed with this intern. These improvements in skill may improve patient outcomes and survival rates. We propose further educational research with high-fidelity simulation in the area of assessing emergency skills.

Abstract
OBJECTIVE. Airway management and endotracheal intubation may be required urgently when a patient deteriorates in an ambulance or aircraft during interhospital transfer or in a prehospital setting. The objectives of this study were: (1) to compare the effectiveness of conventional intubation by Macintosh laryngoscope in a moving ambulance versus that in a static ambulance; and (2) to compare the effectiveness of inverse intubation and GlideScope laryngoscopy with conventional intubation inside a moving ambulance. DESIGN. Comparative experimental study. SETTING. The experiment was conducted in an ambulance provided by the Auxiliary Medical Service in Hong Kong. PARTICIPANTS. A group of 22 doctors performed endotracheal intubation on manikins with Macintosh laryngoscope in a static and moving ambulance. In addition, they performed conventional Macintosh intubation, inverse intubation with Macintosh laryngoscope, and GlideScope intubation in a moving ambulance in both normal and simulated difficult airways. MAIN OUTCOME MEASURES. The primary outcome was the rate of successful intubation. The secondary outcomes were time taken for intubation, subjective glottis visualisation grading, and eventful intubation (oesophageal intubation, intubation time >60 seconds, and incisor breakage) with different techniques or devices. RESULTS. In normal airways, conventional Macintosh intubation in a static ambulance (95.5%), conventional intubation in a moving ambulance (95.5%), as well as GlideScope intubation in a moving ambulance (95.5%) were associated with high success rates; the success rate of inverse intubation was comparatively low (54.5%; P=0.004). In difficult airways, conventional Macintosh intubation in a static ambulance (86.4%), conventional intubation in a moving ambulance (90.9%), and GlideScope intubation in a moving ambulance (100%) were associated with high success rates; the success rate of inverse intubation was comparatively lower (40.9%; P=0.034). CONCLUSIONS. En-route intubation in an ambulance by conventional Macintosh laryngoscopy is superior to inverse intubation unless the cephalad access is impossible. GlideScope laryngoscopy appears to be associated with lower rates of eventful intubation in difficult airways and has better laryngoscopic view versus inverse intubation.
