Simulation-Based Training Program for Peripherally Inserted Central Catheter Placement: Randomized Comparative Study of in-Person Training With Synchronous Feedback Versus Distance Training With Asynchronous Feedback.

INTRODUCTION: Simulation training that includes deliberate practice is effective for procedural skill training. Delivering feedback remotely and asynchronously has been examined for more cost-efficient training. This prospective randomized study aimed to compare 2 feedback techniques for simulation training: synchronous direct feedback versus asynchronous distance feedback (ASYNC). METHODS: Forty anesthesia and internal medicine residents were recruited after study approval by the institutional ethics committee. Residents reviewed instructional material on an online platform and performed a pretraining assessment (PRE) for peripherally inserted central catheter (PICC) placement. Each resident was then randomly assigned to 1 of 2 training types, practice with synchronous direct feedback (SYNC) or practice with ASYNC. Training consisted of four, 1-hour practice sessions; each was conducted once per week. Both groups underwent posttraining evaluation (POST). The PRE and POST assessments were videotaped and evaluated by 2 independent, blinded reviewers using a global rating scale. RESULTS: Thirty-five residents completed the training program and both evaluations. Both groups had significantly improved global rating scale scores after 4 sessions. The SYNC group improved from 28 to 45 points (P < 0.01); the ASYNC group improved from 26.5 to 46 points (P < 0.01). We found no significant between-group differences for the PRE (P = 0.42) or POST assessments (P = 0.13). CONCLUSION: This simulation-based training program significantly improved residents' peripherally inserted central venous catheter placement skills using either modality. With these results, we are unable to demonstrate the superiority of synchronous feedback over ASYNC. Asynchronous feedback training modality represents a new, innovative approach for health care procedural skills training.

Health Care Simulation as a Training Tool for Epidemic Management: A Systematic Review.

SUMMARY STATEMENT: The objective of this research was to identify and review studies that have evaluated the impact of simulation-based training on health care professionals during epidemics.All studies in health care simulation-based training published during the last 5 epidemics with a global impact (SARS-CoV, H1N1, MERS, Ebola, SARS-CoV-2; through July 2021) were selected from a systematic search of PUBMED, EMBASE, and key journals.The search strategy identified 274 studies; 148 met the inclusion criteria and were included. Most of the studies were developed in response to SARS-CoV-2 infection (n = 117, 79.1%), used a descriptive approach (n = 54, 36.5%), and were used to train technical skills (n = 82, 55.4%).This review demonstrates a growing interest in publications related to health care simulation and epidemics. Most of the literature is marked by limited study designs and outcome measurements, although there is a trend toward the use of more refined methodologies in the most recent publications. Further research should seek the best evidence-based instructional strategies to design training programs in preparation for future outbreaks.

Designing Sustainable Solutions to Implement a Distance-Based Simulation Basic Life Support Training Program During COVID-19 Pandemic in Low-Income Countries.

SUMMARY STATEMENT: The global pandemic of COVID-19 had strong repercussions in healthcare simulation-based education around the world. Different adaptations to imposed restraints such as social distancing have been developed to address the educational needs of healthcare professionals. However, the lack of access to simulators in low-income countries or rural areas may restrict the access to distance simulation-based training.

Implementation of Distance-Based Simulation Training Programs for Healthcare Professionals: Breaking Barriers During COVID-19 Pandemic.

SUMMARY STATEMENT: The sudden rise of critically ill patients secondary to the SARS-CoV-2 pandemic has triggered a surge in healthcare response. This project's goal was to provide essential cognitive and technical skills to healthcare professionals returning to the workforce or reassigned to critical care clinical duties during the COVID-19 pandemic. The plan included the implementation of 4 distance-based simulation training programs, with asynchronous personalized feedback. The courses allowed the acquisition of skills for the complete critical care patient management chain: use of personal protection equipment, use of a high-flow nasal cannula, endotracheal intubation, and prone positioning. Participants logged into the platform, reviewed material, practiced while recording the session, and uploaded the video through the training platform. The expert tutor remotely delivered asynchronous feedback. Participants trained remotely until achieving course approval. Remote-based simulation seems a feasible and attractive alternative to provide adequate educational solutions, especially for remote and rural areas.

Implementación del Primer Examen Clínico Objetivo Estructurado (ECOE) para la Certificación de la Especialidad en Anestesiología en Chile

Anesthesiology became the first Chilean medical specialty certification board to incorporate an objective structured clinical examination (OSCE) into its certification system. The main reason for the introduction of an OSCE is to include an evaluation that allow candidates to demonstrate what they really "do" in clinical practice domains. Inherent in this justification is that the OSCE detects competences that are not well evaluated in current written and oral exams. This article describes the process of implementing an OSCE in Anesthesiology certification and a description of its application after one year of operation.

Perioperative lumbar plexus block and cardiac ischemia in patients with hip fracture: randomized clinical trial / Bloqueio perioperatório do plexo lombar e isquemia cardíaca em pacientes com fratura de quadril: ensaio clínico randomizado

Abstract Background Perioperative myocardial ischemia is common among patients undergoing hip fracture surgery. Our aim is to evaluate the efficacy of perioperative continuous lumbar plexus block in reducing the risk of cardiac ischemic events of elderly patients undergoing surgery for hip fractures, expressed as a reduction of ischemic events per subject. Methods Patients older than 60 years, ASA II-III, with risk factors for or known coronary artery disease were enrolled in this randomized controlled study. Patients were randomized to conventional analgesia using opioid intravenous patient-controlled analgesia or continuous lumbar plexus block analgesia, both started preoperatively and maintained until postoperative day three. Continuous electrocardiogram monitoring with ST segment analysis was recorded. Serial cardiac enzymes and pain scores were registered during the entire period. We measured the incidence of ischemic events per subject registered by a continuous ST-segment Holter monitoring. Results Thirty-one patients (intravenous patient-controlled analgesia 14, lumbar plexus 17) were enrolled. There were no major cardiac events during the observation period. The number of ischemic events recorded by subject during the observation period was 6 in the lumbar plexus group and 3 in the intravenous patient-controlled analgesia group. This difference was not statistically significant (p = 0.618). There were no statistically significant differences in the number of cases with increased perioperative troponin values (3 cases in the lumbar plexus group and 1 case in the intravenous patient-controlled analgesia group) or in terms of pain scores. Conclusions Using continuous perineural analgesia, compared with conventional systemic analgesia, does not modify the incidence of perioperative cardiac ischemic events of elderly patients with hip fracture.

Resumo Justificativa A isquemia miocárdica perioperatória é comum em pacientes submetidos à cirurgia de fratura de quadril. Nosso objetivo foi avaliar a eficácia do bloqueio perioperatório contínuo do plexo lombar na redução do risco de eventos cardíacos isquêmicos em pacientes idosos submetidos à cirurgia para fraturas de quadril, expresso como uma redução de eventos isquêmicos por indivíduo. Métodos Pacientes com mais de 60 anos de idade, ASA II-III com fatores de risco para ou com doença coronariana conhecida foram incluídos neste estudo controlado e randomizado. Os pacientes foram aleatorizados para analgesia convencional usando analgésicos opioides para administração de analgesia intravenosa controlada pelo paciente (Intravenous Patient-Controlled Analgesia - IVPCA) ou analgesia contínua com o bloqueio do Plexo Lombar (PL), ambas iniciadas no pré-operatório e mantidas até o terceiro dia de pós-operatório. Monitoração contínua de ECG com análise do segmento ST foi registrada. Enzimas cardíacas seriadas e escores de dor foram registrados durante todo o período. Medimos a incidência de eventos isquêmicos por indivíduo registrados com monitoração contínua do segmento ST via Holter. Resultados Trinta e um pacientes (IVPCA 14, PL 17) foram incluídos. Não houve eventos cardíacos sérios durante o período de observação. O número de eventos isquêmicos registrados por sujeito durante o período de observação foi de seis no grupo PL e três no grupo IVPCA. Essa diferença não foi estatisticamente significativa (p = 0,618). Não houve diferenças estatisticamente significativas no número de casos com aumento dos valores de troponina no perioperatório (três casos no grupo LP e um caso no grupo IVPCA) ou em termos de escores de dor. Conclusões O uso da analgesia perineural contínua comparado ao da analgesia sistêmica convencional não modifica a incidência de eventos isquêmicos cardíacos no período perioperatório de pacientes idosos com fratura de quadril.

Acquiring skills in malignant hyperthermia crisis management: comparison of high-fidelity simulation versus computer-based case study / Adquirir habilidades no manejo de crises de hipertermia maligna: comparação de simulação de alta-fidelidade versus estudo de caso em computador

Abstract Introduction: The primary purpose of this study was to compare the effect of high fidelity simulation versus a computer-based case solving self-study, in skills acquisition about malignant hyperthermia on first year anesthesiology residents. Methods: After institutional ethical committee approval, 31 first year anesthesiology residents were enrolled in this prospective randomized single-blinded study. Participants were randomized to either a High Fidelity Simulation Scenario or a computer-based Case Study about malignant hyperthermia. After the intervention, all subjects' performance in was assessed through a high fidelity simulation scenario using a previously validated assessment rubric. Additionally, knowledge tests and a satisfaction survey were applied. Finally, a semi-structured interview was done to assess self-perception of reasoning process and decision-making. Results: 28 first year residents finished successfully the study. Resident's management skill scores were globally higher in High Fidelity Simulation versus Case Study, however they were significant in 4 of the 8 performance rubric elements: recognize signs and symptoms (p = 0.025), prioritization of initial actions of management (p = 0.003), recognize complications (p = 0.025) and communication (p = 0.025). Average scores from pre- and post-test knowledge questionnaires improved from 74% to 85% in the High Fidelity Simulation group, and decreased from 78% to 75% in the Case Study group (p = 0.032). Regarding the qualitative analysis, there was no difference in factors influencing the student's process of reasoning and decision-making with both teaching strategies. Conclusion: Simulation-based training with a malignant hyperthermia high-fidelity scenario was superior to computer-based case study, improving knowledge and skills in malignant hyperthermia crisis management, with a very good satisfaction level in anesthesia residents.

Resumo Introdução: O objetivo primário deste estudo foi comparar o efeito da simulação de alta-fidelidade versus autoestudo baseado em resolução de casos no computador, a aquisição de habilidades sobre hipertermia maligna em residentes de anestesiologia do primeiro ano. Métodos: Após a aprovação do Comitê de Ética institucional, 31 residentes de anestesiologia do primeiro ano foram inscritos neste estudo prospectivo, randômico e encoberto. Os participantes foram randomizados para um ambiente de simulação de alta-fidelidade (SAF) ou um estudo de caso (EC) em computador sobre hipertermia maligna. Após a intervenção, o desempenho de todos os indivíduos foi avaliado através de um ambiente de simulação de alta-fidelidade utilizando uma rubrica de avaliação previamente validada. Além disso, uma pesquisa de satisfação e testes de conhecimento foram aplicados. Por fim, uma entrevista semiestruturada foi realizada para avaliar a autopercepção do processo de raciocínio e da tomada de decisão. Resultados: Vinte e oito residentes do primeiro ano concluíram o estudo com sucesso. Os escores dos residentes na aquisição de habilidades no manejo da hipertermia maligna foram globalmente maiores no Grupo SAF que no Grupo EC, mas a significância foi em quatro dos oito elementos da rubrica de desempenho: reconhecer os sinais e sintomas (p = 0,025), priorizaras ações iniciais do manejo (p = 0,003), reconhecer complicações (p = 0,025) e comunicação (p = 0,025). As médias dos escores nos questionários de conhecimento pré- e pós-teste melhoraram de 74% para 85% no Grupo SAF e diminuíram de 78% para 75% no Grupo EC (p = 0,032). Em relação à análise qualitativa, não houve diferença nos fatores que influenciaram o processo de raciocínio e de tomada de decisão dos alunos com ambas as estratégias de ensino. Conclusão: O treinamento baseado em simulação com um ambiente de alta-fidelidade de hipertermia maligna foi superior ao estudo de caso em computador, melhorou o conhecimento e as habilidades no manejo de crises de hipertermia maligna, com um nível de satisfação muito bom entre os residentes de anestesia.

Validation of the imperial college surgical assessment device for spinal anesthesia.

BACKGROUND: Traditionally, technical proficiency for spinal anesthesia has been assessed using observational scales such as global rating scales or task specific checklists. However more objective metrics are required in order to improve novice's training programs. The aim of this study is to validate the hand motion analysis of the Imperial College Surgical Assessment Device (ICSAD) in a simulated model of spinal anesthesia. METHODS: Three groups of physicians with different levels of experience were video recorded performing a spinal anesthesia in a simulated lumbar puncture torso. Participants' technical performance was assessed with ICSAD, a Global Rating Scale (GRS) and a specific Checklist. Differences between the 3 groups were determined by Kruskal-Wallis test with post hoc Dunn's correction for multiple comparisons. Spearman correlation coefficient between ICSAD variables and the scores of the observational scales were calculated to establish concurrent validity. RESULTS: Thirty subjects participated in the study: ten novice (first year residents), 10 intermediate (third year residents) and 10 experts (attending anesthesiologists). GRS scores were significantly higher in experts, than intermediates and novices. Regarding total path length, number of movements and procedural time measured with ICSAD, all groups had significant differences between them (p = 0.026, p = 0.045 and p = 0.005 respectively). Spearman correlation coefficient was -0,46 (p = 0.012) between total path length measured with ICSAD and GRS scores. CONCLUSIONS: This is the first validation study of ICSAD as an assessment tool for spinal anesthesia in a simulated model. Using ICSAD can discriminate proficiency between expert and novices and correlates with previously validated GRS. Its use in the assessment of spinal anesthesia proficiency provides complementary data to existing tools. Our results could be used to design future training programs with reliable goals to accomplish.

Which types of peripheral nerve blocks should be included in residency training programs?

BACKGROUND: Despite the increasing use of regional anesthesia, specific recommendations regarding the type of procedures to be included in residency training programs are not currently available. We aimed to determine the nerve block techniques that practicing Chilean anesthesiologists perceived as essential to master during residency training. METHODS: After institutional ethics committee approval, an online survey was sent to 154 anesthesiologists that graduated between 2005-2012, from the two largest university residency programs in Chile. Multiple-choice questions elicited responses concerning the use of regional anesthesia. RESULTS: A total of 109 questionnaires were completed, which corresponded to a response rate of 70.8%. Almost all (98.2%) of the respondents used regional anesthesia in their clinical practice, 86.7% regularly performed peripheral nerve blocks (PNBs) and 51% used continuous PNB techniques. Residency programs represented their primary source of training. The most common PNB techniques performed were interscalene (100%), femoral (98%), popliteal sciatic (93%), and Bier block (90%). Respondents indicated that they were most confident performing femoral (98%), Bier block (90%), interscalene (90%), and popliteal sciatic (85%) blocks. The PNBs perceived as essential for their actual clinical practice were femoral (81%), interscalene (80%), popliteal sciatic (76%), and Bier blocks (62%). CONCLUSIONS: Requesting information from former anesthesiology residents may be a source of information, guiding the specific types of PNBs that should be included in residency training. Other groups can easily replicate this methodology to create their own evidence and clinical practice based guidelines for residency training programs.

To die or not to die? A review of simulated death.

SUMMARY STATEMENT: Simulation as an educational technique is increasingly used in health care to teach about managing critical events and life-threatening situations and, infrequently, to teach about death. There is considerable controversy over whether to allow the simulator to die during a session when death is not a predefined learning objective. Some educators never allow the simulator to die unless death is the objective of the scenario, and others allow the simulator to die unexpectedly during any scenario. We do not know whether such a fatal event may affect a student's learning process and emotions, and no randomized trials have been conducted to determine the impact of simulated death. In this narrative review, we survey the literature on simulated death during health care training, present arguments for and against the broad incorporation of such training in curricula for health care providers, and outline recommendations for using death scenarios in health care simulation.

Comparison of plasma concentrations of levobupivacaine with and without epinephrine for transversus abdominis plane block.

BACKGROUND AND OBJECTIVES: The pharmacokinetics for levobupivacaine in transversus abdominis plane (TAP) blocks has not been previously reported. We aimed to determine the extent of the block and the effect on plasma concentrations of levobupivacaine with the addition of epinephrine. METHODS: We enrolled 11 healthy volunteers in this double-blind, 2-intervention, 2-period crossover study. The intervention periods were defined as a unilateral left TAP block with 20 mL of 0.25% levobupivacaine with (E) or without (no E) 5 µg/mL epinephrine. Subjects were randomized to E, followed by no E or no E followed by E, with 2-week washout period. Sensory dermatomal anesthesia was recorded. Blood samples were obtained for the measurement of plasma levobupivacaine levels. RESULTS: The median cranial-to-caudal spread of sensory blockade for sharp touch was T9 (interquartile range [IQR], T7-T10) to L1 (IQR, T12-L1) with epinephrine and T9 (IQR, T8-T10) to T12 (IQR, T11-L1) without epinephrine (P > 0.05). The mean maximum arterial levobupivacaine concentrations with epinephrine were 0.36 (95% bootstrap confidence interval [95% CI], 0.30-0.42) µg/mL and 0.63 (95% CI, 0.49-0.85) µg/mL without epinephrine (P = 0.014, difference in means of 0.27 [95% CI, 0.12-0.46]). The mean maximal venous levobupivacaine concentration was 0.32 (95% CI, 0.28-0.39) µg/mL and 0.49 (95% CI, 0.37-0.68) µg/mL, with and without epinephrine, respectively (P = 0.006, difference in means of 0.17 [95% CI, 0.08-0.33]). The mean duration of the blockade was 10.2 hours (95% CI, 8.5-12.5 hours) with epinephrine and 10.3 hours (95% CI, 8.7-12.4 hours) without epinephrine (P = 1.000). CONCLUSIONS: Adding epinephrine to levobupivacaine reduces its peak plasma concentration after unilateral TAP blocks, with no remarkable effects on block characteristics or duration.

Brief report: The sensitivity of motor responses for detecting catheter-nerve contact during ultrasound-guided femoral nerve blocks with stimulating catheters.

BACKGROUND: We determined the sensitivity of motor responses evoked by stimulating catheters in determining catheter-nerve contact using ultrasonography as reference. METHODS: Femoral nerves were contacted using stimulating catheters under ultrasonography scanning in 25 patients. The output current was increased from its minimum until quadriceps muscle contraction occurred. The sensitivity of the motor response in determining catheter-nerve contact was calculated using 0.5 mA as current threshold. RESULTS: The current required for catheter stimulation to evoke a motor response ranged between 0.18 and 2.0 mA. Muscle contraction in response to 0.5 mA occurred in 16 of 25 subjects. The sensitivity of motor response for nerve stimulation was 64% (95% confidence interval: 0.43, 0.82). CONCLUSIONS: The absence of muscle responses at a stimulating current≤0.5 mA does not necessarily indicate the absence of catheter-nerve contact.

The "Simulation Roulette" game.

INTRODUCTION: "Simulation Roulette" is a new method of "on-the-fly" simulation scenario creation that incorporates a game-like approach to critical scenarios and emphasizes prescenario preparation. We designed it to complement our traditional anesthesia simulation curriculum, in which residents are exposed to predefined "critical" scenarios. During typical scenarios, trainees are often given minimum preparatory information; they then start the scenario knowing only that "something bad" is going to happen. As a result, trainees often report anxiety, which can be a barrier to learning. To overcome this barrier and to augment traditional critical incident training, we developed the "Simulation Roulette" game. METHODS: "Simulation Roulette" consists of premade cards that are randomly selected to create a patient, another set of premade cards to assist in selecting "complications," worksheets to guide a thorough "prebrief" discussion before the scenario, and scoresheets to facilitate the "debrief" discussion at the end. Similar to traditional scenarios, it requires coordination by a facilitator to ensure plausible scenarios and evaluation of trainee performance. RESULTS: Although we have not conducted formal testing, we believe that (1) incorporating an element of random chance to scenario selection, (2) using a game-like framework, and (3) emphasizing the "prebrief" portion of simulation all have the potential to decrease trainee anxiety. CONCLUSIONS: We present the rationale for designing such a game; examples of instructions, cards, and scoresheets; and our initial experience with implementing this game within our simulation curriculum.
