Cross-cultural adaptation and validation of the Spanish version of the Anesthetists' Non-Technical Skills (ANTS) assessment tool.

STUDY OBJECTIVE: Establish the transcultural validity of Anesthetists Non-Technical Skills (ANTS) in a Spanish-speaking country. DESIGN: Prospective cohort. SETTING: Clinical simulation center. SUBJECTS: Forty-two Anesthesia PY2 and PY3 residents participated in the study. INTERVENTIONS: Four clinical scenarios simulating anesthesia crises were assessed with a Spanish version of ANTS. Every simulated scenario was run twice with a time span of 3 to 4 months between them. MEASUREMENTS: Two anesthesiologists independently assessed all simulated sessions using ANTS. The ANTS indicators of construct validity were obtained by confirmatory factor analysis. Various goodness-of-fit indices of the factorial model were calculated: Comparative Fit Index (CFI); Tucker-Lewis Adjustment Index (TLI) and Root Mean Square Error of Approximation (RMSEA). The standardized factor loadings and the determination coefficient (R2) was also estimated. MAIN RESULTS: A total of 212 clinical scenarios were analyzed. The specified factorial model had the same grouping of elements in four domains as the original version of ANTS. The CFI index and the TLI were 0.99 and the RMSEA reached 0.07 (95% CI 0.06-0.08). All the standardized factor loadings were found to be >0.4. Also, the elements obtained an R2 value that fluctuated between 0.54 and 0.92. CONCLUSIONS: The Spanish version of ANTS is a valid, reliable and a useful tool to assess non-technical skills in Spanish-speaking countries. The applicability of the instrument was comparable to the original setting. The high reliability of ANTS in our setting allows us to propose its use not just in an educational and research setting; it can be used as an assessment tool of non-technical skills.

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.

Process-Oriented Feedback through Process Mining for Surgical Procedures in Medical Training: The Ultrasound-Guided Central Venous Catheter Placement Case.

Developing high levels of competence in the execution of surgical procedures through training is a key factor for obtaining good clinical results in healthcare. To improve the effectiveness of the training, it is advisable to provide feedback to each student tailored to how the student has performed the procedure on each occasion. Current state-of-the-art feedback is based on Checklists and Global Rating Scales, which indicate whether all process steps have been carried out and the quality of each execution step. However, there is a process perspective that is not captured successfully by these instruments, e.g., steps performed, but in an undesired order, group of activities that are repeated an unnecessary number of times, or an excessive transition time between two consecutive steps. In this research, we propose a novel use of process mining techniques to effectively identify desired and undesired process patterns regarding rework, the order in which activities are performed, and time performance, in order to complement the tailored feedback for surgical procedures using a process perspective. The proposed approach was applied to analyze a real case of ultrasound-guided Central Venous Catheter placement training. It was quantitatively and qualitatively validated that the students who participated in the training program perceived the process-oriented feedback they received as favorable for their learning.

A basic anesthesia training program for nurses in Chad: first steps for a south-south academic cooperation program.

PURPOSE: Safe perioperative care remains a large public healthcare problem in low- and middle-income countries. Anesthesia care provided by trained professionals is one of the essential determinants to address this situation. This article reports the design and implementation of a focused anesthesia educational program for nurses in Chad. METHOD: This program consisted of four full-time courses of one month each, taught in a local hospital. The program included supervised practice in the operating room and post-anesthesia recovery room, skills lab simulation training, high fidelity crisis simulation, theoretical classes, integration sessions, evaluations, and structured feedback sessions. RESULTS: Seven male nurses, aged 28-40 yr, were accepted and successfully completed the program. The median [interquartile range] students' global satisfaction with the program was high (86 [85-93]%). Cognitive and skills assessment improved significantly after the program. Students subsequently worked in city and district hospitals performing essential and emergency surgical interventions. CONCLUSIONS: This is a novel south-south academic cooperation program for nurses in Chad. The program evaluation indicated a high level of satisfaction, effective cognitive and skills learning, and changes in clinical behaviour. Addressing the lack of adequate provision of anesthesia care is a task still to be faced, and this program depicts a bridge alternative until formal educational programs are implemented in the country.

RéSUMé: OBJECTIF: Des soins périopératoires sécuritaires demeurent un important problème de santé publique dans les pays à faible et à moyen revenu. Les soins anesthésiques offerts par des professionnels formés constituent l'un des éléments déterminants essentiels pour régler le problème. Cet article rapporte la conception et la mise en œuvre d'un programme spécialisé de formation en anesthésie s'adressant au personnel infirmier au Tchad. MéTHODE: Ce programme était composé de quatre cours intensifs d'une durée d'un mois chacun, donnés dans un hôpital local. Le programme comportait une pratique supervisée en salle d'opération et en salle de réveil, des séances pratiques en laboratoire de simulation, une simulation de crise haute fidélité, des classes théoriques, des séances d'intégration, des évaluations et des séances de rétroaction structurées. RéSULTATS: Sept infirmiers âgés de 28 à 40 ans ont été acceptés dans le programme et l'ont terminé avec succès. La satisfaction globale moyenne [écart interquartile] des étudiants était élevée (86 [85­93] %). L'évaluation cognitive et des connaissances s'est considérablement améliorée après avoir suivi le programme. Les étudiants ont par la suite travaillé dans des hôpitaux de ville et de district réalisant des interventions chirurgicales essentielles et urgentes. CONCLUSION: Il s'agit d'un programme de coopération universitaire sud-sud innovant au Tchad. L'évaluation du programme a indiqué un niveau élevé de satisfaction, un apprentissage efficace au niveau cognitif et des compétences, ainsi que des changements au niveau du comportement clinique. Il reste encore beaucoup de travail pour régler le problème suscité par l'absence d'une offre adéquate de soins anesthésiques, et ce programme décrit une alternative temporaire intéressante jusqu'à ce que des programmes de formation formels soient mis en œuvre dans ce pays.

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.

La simulación puede mejorar la seguridad de los pacientes sometidos a procedimientos endoscópicos gastrointestinales bajo sedación / Simulation can improve patients’ security in gastrointestinal endoscopic procedures under sedation

background: Appropriate sedation is crucial for a successful gastrointestinal endoscopy procedure (GEP); however, this is associated with adverse events, therefore adequate capacitation in this subject is mandatory. Simulation is an excellent teaching tool but its use in the setting of sedation teaching for GEP has not bee explored. The aim of this study was to assess the impact of a simulation course on sedation for GEP procedures done by endoscopist. Methods: A checklist to assess the endoscopists’ sedation performance for GEP was developed. This checklist was used to assess the sedations’ quality before and after a high fidelity sedation simulation course for GEP. Differences before/after the intervention was calculated using the McNemar’s test. A p ≤ 0,05 was considered significant. Results: All participants were assessed 15 times pre and post intervention. After the simulation, there was a significant improvement in patients’ airway assessment, in the level of awareness about patients’ condition during the procedure and in the monitoring after the procedure. All participants considered simulation should be compulsory before obtaining a license to sedate patients. Conclusions: The implementation of a sedation course based on simulation cases directed to endoscopists improved patient safety and sedations’ quality during the procedure. Simulation should be considered as a valid teaching tool, which is an enormous challenge to the anaesthesiologists.

Introducción: Una adecuada sedación contribuye al éxito de un procedimiento endoscópico gastrointestinal (PEG); sin embargo, esto puede estar asociado a eventos adversos, siendo importante la capacitación al respecto. La simulación es una excelente herramienta docente, pero su uso en la enseñanza de sedación para PEG no ha sido explorada. El objetivo de este estudio fue evaluar el impacto de un curso de sedación para PEG dirigido a endoscopistas basado en simulación. Materiales y Métodos: Se diseño una lista de cotejo para evaluar la calidad de la sedación impartida por endoscopistas durante PEG. Con dicho instrumento se determinó la calidad de la sedación antes y después de un curso de simulación de alta fidelidad sobre sedación para PEG. La magnitud de las diferencias secundario a la intervención se calcularon utilizando el test de McNemar. Una p ≤ 0,05 se consideró significativa. Resultados: Todos los participantes fueron evaluados 15 veces antes y después de la intervención. Después de la intervención, mejoró significativamente la evaluación de vía aérea, el nivel de alerta por las condiciones del paciente durante el procedimiento y el seguimiento posterior. Todos los participantes consideraron que la simulación debería ser obligatoria antes de obtener privilegios clínicos. Conclusiones: La implementación de un curso de sedación basados en simulación dirigidos a endoscopistas mejora la calidad de esta y la seguridad del paciente durante el procedimiento. La simulación debe ser considerada como una estrategia de enseñanza válida en este contexto lo que plantea un gran desafío a todos los anestesiólogos.

Evaluation of Radiology Teachers' Performance and Identification of the "Best Teachers" in a Residency Program: Mixed Methodology and Pilot Study of the MEDUC-RX32 Questionnaire.

RATIONALE AND OBJECTIVES: Radiology teachers are well trained in their specialty; however, when working in academic institutions, faculty development and promotion through the education pathway tends to be based on their teaching knowledge and skills. The aim of this study is to assess psychometric properties of the Medicina Universidad Católica-Radiology 32 items (MEDUC-RX32), an instrument designed to evaluate the performance of postgraduate radiology teachers and to identify the best teachers. MATERIALS AND METHODS: Mixed methodology was used, including qualitative and quantitative phases. The psychometric properties of the MEDUC-RX32 survey were performed by factor analysis (validity), Cronbach alpha coefficient, and G coefficient (reliability). The residents assessed their teachers and simultaneously voted for the "best teacher," which was used as a gold standard for the receiver operating characteristic curves construction comparing their votes with the global score. RESULTS: A total of 28 residents answered 164 surveys. The global score was 6.23 ± 0.8 (scale from 1 to 7). The factor analysis showed six domains of the resident's perception: (1) tutorial teaching, feedback, and independent learning; (2) communication and teamwork; (3) learning objectives; (4) respectful behavior; (5) radiological report; and (6) teaching and care support. The tutor's strengths were related with respectful behavior and teamwork. The instrument is highly reliable with a Cronbach alpha of 0.937 and a G coefficient of 0.831 (with a minimum of 8 residents). The MEDUC-RX32 instrument has a sensitivity of 91.7% and specificity of 83.3% to identify tutors as best teachers with at least one vote with an area under the receiver operating characteristic curve of 0.931 with a cutoff of 5.94. CONCLUSIONS: The MEDC-RX32 instrument is a multidimensional, valid, and highly reliable method to evaluate radiology teachers, identifying teachers with excellence in tutorial teaching in a postgraduate radiology program.

Nivel de correlación en la evaluación de la intubación traqueal efectuada por anestesiólogos docentes y residentes de anestesiología / Level of correlation in the assessment of tracheal intubation between anaesthesiology staff and residents

Introducción: La educación médica ha experimentado numerosos cambios. Uno de éstos es el uso de la autoevaluación para establecer la progresión de los estudiantes. Hasta donde sabemos, en la realidad chilena no existen hasta el momento estudios sobre la validez y confiabilidad del uso de la autoevaluación en el proceso educacional. Sujetos y métodos: Las intubaciones traqueales efectuadas durante cuatro meses por los residentes de anestesia de la Pontificia Universidad Católica de Chile se evaluaron utilizando el instrumento 'observación directa de procedimientos y habilidades' (DOPS). Una vez intubado el paciente, el anestesiólogo a cargo efectuó la evaluación inmediata de la técnica de intubación del residente. A su vez, empleando el mismo instrumento, el residente efectuó una autoevaluación del mismo procedimiento. El nivel de acuerdo entre anestesiólogo y residente se estableció mediante el índice de correlación intraclase (ICC). Se realizó una encuesta de opinión sobre el método entre los participantes. Resultados: Se evaluaron 585 intubaciones. Participaron 31 residentes y 30 anestesiólogos. El ICC general fue 0,423. Éste disminuyó a medida que aumentaba el nivel de experiencia de los estudiantes, y alcanzó el nivel más bajo en los residentes de tercer año, con un ICC de 0,39. Anestesiólogos y residentes manifestaron satisfacción con el método, pero poca experiencia previa. Conclusiones: El nivel de concordancia entre las evaluaciones y autoevaluaciones fue bajo. La falta de experiencia previa de los participantes pudo influir en los resultados. Para utilizar adecuadamente instrumentos de autoevaluación, éstos deberían implementarse desde etapas tempranas de la formación

Introduction: The medical education has experienced numerous changes. One of these is the use of self-assessment to establish students’ progress, even with summative purposes. As far as we know, in our setting there are not studies about the validity and reliability of the use of self-assessment in the educational process. Subjects and methods: The intubations performed during four months by anesthesia residents at Pontificia Universidad Católica de Chile were assessed using the instrument Direct Observation of Procedural Skills (DOPS). Once the patient was intubated, the anesthesia staff in charge of patient’s care carried out the resident’s assessment and each student performed a self-assessment of the procedure using the same instrument. The level of agreement between staffs and students was established using intraclass correlation (ICC). An opinion survey among the participants about the method was performed. Results: 585 intubations were assessed. 31 students and 30 staff participated in the study. The general ICC was 0.423. The ICC decreased according to the residents' student year reaching the bottom at third year residents with 0.39. All participants were satisfied with the method but they pointed out the lack of previous experience. Conclusions: The agreement between staffs' assessments and students’ self-assessment was poor. The lack of participants' experience could affect the results. To properly use self-assessment instruments, they should be implemented in early stages of educational process

[Development of MEDUC-PG14 survey to assess postgraduate teaching in medical specialties]. / Evaluación de docentes clínicos de Postgrado: desarrollo y propiedades psicométricas del instrumento MEDUC-PG14.

BACKGROUND: Feedback is one of the most important tools to improve teaching in medical education. AIM: To develop an instrument to assess the performance of clinical postgraduate teachers in medical specialties. MATERIAL AND METHODS: A qualitative methodology consisting in interviews and focus-groups followed by a quantitative methodology to generate consensus, was employed. After generating the instrument, psychometric tests were performed to assess the construct validity (factor analysis) and reliability (Cronbach’s alpha). RESULTS: Experts in medical education, teachers and residents of a medical school participated in interviews and focus groups. With this information, 26 categories (79 items) were proposed and reduced to 14 items (Likert scale 1-5) by an expert’s Delphi panel, generating the MEDUC-PG14 survey, which was answered by 123 residents from different programs of medical specialties. Construct validity was carried out. Factor analysis showed three domains: Teaching and evaluation, respectful behavior towards patients and health care team, and providing feedback. The global score was 4.46 ± 0.94 (89% of the maximum). One teachers’ strength, as evaluated by their residents was “respectful behavior” with 4.85 ± 0.42 (97% of the maximum). “Providing feedback” obtained 4.09 ± 1.0 points (81.8% of the maximum). MEDUC-PG14 survey had a Cronbach’s alpha coefficient of 0.947. CONCLUSIONS: MEDUC-PG14 survey is a useful and reliable guide for teacher evaluation in medical specialty programs. Also provides feedback to improve educational skills of postgraduate clinical teachers.

[Introduction of virtual patients to clinical case portfolios for undergraduate medical students]. / Incorporación de paciente virtual en portafolio de estudiantes de medicina de pregrado.

BACKGROUND: In 2007, a Clinical-Case-Portfolio (CCP) was introduced as a new assessment instrument for fourth grade undergraduate medical students. Since then, several changes have been implemented such as reduction on the number of clinical cases, peer review and the introduction of virtual patient to the portfolio. AIM: To describe the virtual patient model incorporated to the CCP and assess the perception of this change and its effects on the performance of undergraduate students. MATERIAL AND METHODS: Virtual patients were implemented based on prototype clinical cases with specific syndromes. Students’ perceptions about CCP before and after the introduction of virtual patients were evaluated using a validated questionnaire that was answered voluntarily and anonymously. RESULTS: Overall perception of CCP significantly improved after the incorporation of virtual patients (97.1 ± 24.9 and 111.3 ± 25.7 points; 57.8 and 66.2% respectively). The same improvements were observed for the domains “Student Learning”, “Organization and Evaluation”, “Teaching Methodology” and “Integration”. In both years, students obtained high grades in CCP evaluations. However CCP grades were not significantly correlated with integrated final grades. CONCLUSIONS: The incorporation of virtual patients improved undergraduate students’ perception of CCP.

Effect of acute arterial hypertension on morphine requirements and postsurgical pain.

STUDY OBJECTIVE: The study objective was to establish the impact of acute hypertension on morphine's requirements after laparoscopic cholecystectomy. DESIGN: The design was a randomized, simple blinded study. SETTING: The settings were operating room, postoperative recovery area, and first postoperative day. PATIENTS: There were 50 patients, American Society of Anesthesiologists I-II, aged 18-50 years, undergoing elective laparoscopic cholecystectomy with general anesthesia. INTERVENTIONS: Anesthetic management was standardized using propofol for induction, isoflurane for bispectral index (BIS) ranging between 40 and 60, and remifentanil maintained at a constant rate of 0.4 µg kg per minute throughout surgery in all patients. Once intubated, patients were randomly allocated to 1 of 2 groups: hypertensive group: systolic arterial blood pressure was maintained with phenylephrine infusion 20%-30% over baseline; control group: systolic arterial blood pressure was maintained 20%-30% below baseline. All surgical incisions were infiltrated with bupivacaine 0.5%, and every patient received ketorolac 60 mg intravenous. Patient-controlled analgesia with morphine intravenous was used for postoperative analgesia. MEASUREMENTS: Pain visual analogue scale scores, arterial blood pressure, and hyperalgesia were assessed at recovery room every 15 minutes during the first 2 postoperative hours and then at 6, 12, and 24 postoperative hours. Cumulative morphine consumption was registered at 2 and 24 postoperative hours. MAIN RESULTS: The cumulative morphine consumption in the control group was around 18 mg compared with 6 mg in the hypertensive group (P = .019). During the first 75 minutes after surgery, the control group had higher visual analogue scale score pain compared with hypertensive group (P = .005). CONCLUSIONS: The intraoperative acute generation of mild hypertension with phenylephrine reduced postoperative morphine consumption and pain scores after laparoscopic cholecystectomy.

Validation and piloting of direct observation of practical skills tool to assess intubation in the Chilean context.

BACKGROUND: The use of Workplace-Based Assessment (WBA) has increased in recent years. AIMS: To create a modified version of Direct Observation of Procedural Skills (DOPS) adapted to the Chilean context and establish its psychometric properties. METHODS: The content validity of DOPS was established through interviews and consensus survey. To be included in the new version, the respective domain should have been considered by over 80% of interviewers and it should have a Content Validity Index (CVI and kappa statistic over 0.78 and 0.6, respectively. For four months, the new DOPS was used to assess the intubation skills of the anesthesia trainees. Generalizability theory was used to establish reliability and internal consistency. RESULTS: The interview suggested a DOPS with twelve domains. All were included in the final version as the CVI and kappa values were above 0.9 and 0.8, respectively. 585 procedures were assessed. The G coefficient was 0.90. The intubation needs to be assessed with DOPS at least six times to obtain a G coefficient of 0.80. CONCLUSIONS: The modified DOPS was a valid, reliable and practical tool for assessing the intubation procedure. Effort needs to be made to improve the staff's feedback skills.

[Anesthesia awareness]. / Awareness, consecuencias de una experiencia estresante.

Anesthesia awareness, or "unintended intra-operative awareness" occurs during general anesthesia, on the operating table, when a patient has not had enough general anesthetic or analgesic to prevent consciousness or waking up during surgery. According to international studies its global incidence ranges from 0.1 to 0.2%. Its impact on people can be as severe as other traumatic experiences such as natural disasters, violent fights or sexual abuse. The prevalence of symptoms compatible with post traumatic stress disorder can be as high as 50%, after experiencing the awareness phenomenon. This paper reviews the main issues of the awareness phenomenon.
