Association of Personality Traits With the Efficacy of Stress Management Interventions for Medical Students Taking Objective Structured Clinical Examinations.

PURPOSE: Personality traits are associated with psychophysiological stress, but few studies focus on medical students. This study aimed to better understand the association of personality traits with the efficacy of stress management interventions for medical students. METHOD: A randomized controlled trial was conducted with fourth-year students who took the objective structured clinical examination at Bernard University Lyon 1 in December 2021. Students were randomized in cardiac biofeedback, mindfulness, and control groups. Each intervention was implemented for 6 minutes before the examination. Physiological stress levels were collected during the intervention. Psychological stress levels were rated by students at baseline and after the intervention. Personality traits were assessed via the Big-Five Inventory. Interactions between personality traits and the efficacy of the interventions were analyzed using multivariable linear regression models. RESULTS: Four hundred eighty-one students participated. Higher baseline psychological stress levels were associated with higher neuroticism and agreeableness (ß = 10.27, 95% confidence interval (CI) [7.40, 13.13], P < .001 and ß = 3.42, 95% CI [0.98, 5.85], P = .006, respectively) and lower openness (ß = -4.95, 95% CI [-7.40, -2.49], P < .001). As compared to the control intervention, both stress management interventions led to lower levels of psychological (P < .001 for both) and physiological stress levels (biofeedback: P < .001 and mindfulness: P = .009). Biofeedback efficacy varied by extraversion score for psychological (ß = -5.66, 95% CI [-10.83, -0.50], P = .03) and physiological stress reduction (ß = -0.002, 95% CI [-0.003, -0.00004], P = .045). Mindfulness efficacy varied by agreeableness score for psychological stress reduction (ß = -7.87, 95% CI [-13.05, -2.68], P = .003). CONCLUSIONS: Students with a high score in extraversion may benefit more from biofeedback interventions, while students with high scores in agreeableness may benefit more from mindfulness interventions.

Influence of the embedded participant on learners' performance during high-fidelity simulation sessions in healthcare.

BACKGROUND: The embedded participant (EP) plays a key role during a full scale/high-fidelity simulation (HFS) session. He/she is expected to guide the learner towards the achievement of the educational objectives of the scenario. However, his/her influence on learners' performance stands undetermined and this effect remains briefly addressed in the literature. This study primarily aims to assess whether the EP could have an influence on the performance of the learner during a HFS scenario. The secondary aim was to establish an inventory of the EP practices in France. METHODS: This retrospective study was conducted in Lyon Claude Bernard University Health Simulation Centre (France). Anaesthesia and critical care residents in postgraduate years 1 to 5 who were scheduled for their HFS sessions during the 2016 to 2021 academic years were included. Two investigators independently evaluated the resident performance regarding both technical and non-technical skills from video recordings. In addition, a nationwide survey was sent out by email through the networks of the Francophone Healthcare Simulation Society (SoFraSimS, Société Francophone de Simulation en Santé) to collect information on EP practices in French-speaking Simulation centres. RESULTS: From a total of 344 HFS videos analysed, a cohort of 19 experienced EPs was identified. The EPs had an influence on the technical and non-technical performances of the learners. The 147 responses to the survey showed that predefined rules of EP good practice existed in only 36% of the simulation centres and 65% of respondents believed that specific EP training would be justified. CONCLUSION: The EP can exert an influence on the performance of the learners during HFS. For acting as an EP, a great variability of practices and a lack of training are reported by professionals working in simulation centres. These results suggest that more attention must be paid to EP training and attitudes during simulation, especially if summative simulations are extensively developed.

Nurse-to-Nurse Familiarity and Mortality in the Critically Ill: A Multicenter Observational Study.

Rationale: Nurse-to-nurse familiarity at work should strengthen the components of teamwork and enhance its efficiency. However, its impact on patient outcomes in critical care remains poorly investigated. Objectives: To explore the role of nurse-to-nurse familiarity on inpatient deaths during ICU stay. Methods: This was a retrospective observational study in eight adult academic ICUs between January 1, 2011 and December 31, 2016. Measurements and Main Results: Nurse-to-nurse familiarity was measured across day and night 12-hour daily shifts as the mean number of previous collaborations between each nursing team member during previous shifts within the given ICU (suboptimal if <50). Primary outcome was a shift with at least one inpatient death, excluding death of patients with a decision to forego life-sustaining therapy. A multiple modified Poisson regression was computed to identify the determinants of mortality per shift, taking into account ICU, patient characteristics, patient-to-nurse and patient-to-assistant nurse ratios, nurse experience length, and workload. A total of 43,479 patients were admitted, of whom 3,311 (8%) died. The adjusted model showed a lower risk of a shift with mortality when nurse-to-nurse familiarity increased in the shift (relative risk, 0.90; 95% confidence interval per 10 shifts, 0.82-0.98; P = 0.012). Low nurse-to-nurse familiarity during the shift combined with suboptimal patient-to-nurse and patient-to-assistant nurse ratios (suboptimal if >2.5 and >4, respectively) were associated with increased risk of shift with mortality (relative risk, 1.84; 95% confidence interval, 1.15-2.96; P < 0.001). Conclusions: Shifts with low nurse-to-nurse familiarity were associated with an increased risk of patient deaths.

Use of a Digital Cognitive Aid Improves Memorization of Military Caregivers After High-Fidelity Simulations of Combat Casualty Care.

INTRODUCTION: High-fidelity simulation is widely used in the ongoing education of caregivers. However, the complex high-stakes simulated crisis environment affects memorization. This study investigated whether participants would remember more key training messages 3 months after a simulated complex emergency situation if they had used a digital cognitive aid (CA) during the simulations. MATERIALS AND METHODS: This randomized controlled trial was performed during a combat casualty training course for military physicians and nurses. Each pair of care providers completed two scenarios randomized to be undertaken either with or without a digital CA. At the end of each debriefing, instructors gave five scenario-specific key messages aloud. Three months later, learners were asked to recall the messages from their two scenarios and were scored for each scenario. The primary endpoint was the number of key messages recalled. The secondary endpoints were the influence on the results of the profession and the scenario block and age of the leader. RESULTS: Thirty-six pairs of participants were included. Due to operational constraints, only 34 completed the study. The use of the digital CA was associated with a positive effect on memorization at 3 months (F = 82.2, P < .001), unrelated to the leader's profession, age, or the scenario block. The median of the memorization scores was 2/5 [1-3] with the digital CA and 1/5 [1-1] without it, which represents a difference of one memorized element (95% CI, 1-2; η2 = 0.39). CONCLUSIONS: The digital CA allowed learners to remember twice as many key elements 3 months after simulated training of medical care for military combat casualties. A dedicated digital CA might be an asset for better care in a combat environment and for learning and memorizing critical care procedures following complex emergency situations.

Personality traits affect anticipatory stress vulnerability and coping effectiveness in occupational critical care situations.

The present study aimed at investigating the influence of personality on both anticipatory stress vulnerability and the effectiveness of coping strategies in an occupational stressful context. Following assessment of individual personality traits (Big Five Inventory), 147 volunteers were exposed to the anticipation of a stressful event. Anxiety and cardiac reactivity were assessed as markers of vulnerability to anticipatory stress. Participants were then randomly assigned to three groups and subjected to a 5-min intervention: relaxation breathing, relaxation breathing combined with cardiac biofeedback, and control. The effectiveness of coping interventions was determined through the cardiac coherence score achieved during the intervention. Higher neuroticism was associated with higher anticipatory stress vulnerability, whereas higher conscientiousness and extraversion were related to lower anticipatory stress vulnerability. Relaxation breathing and biofeedback coping interventions contributed to improve the cardiac coherence in all participants, albeit with greater effectiveness in individuals presenting higher score of openness to experience. The present findings demonstrated that personality traits are related to both anticipatory stress vulnerability and effectiveness of coping interventions. These results bring new insights into practical guidelines for stress prevention by considering personality traits. Specific practical applications for health professionals, who are likely to manage stressful situations daily, are discussed.

High-Fidelity Simulation to Assess Task Load Index and Performance: A Prospective Observational Study.

OBJECTIVE: The NASA Task Load Index is a questionnaire widely used in aviation. This index might help for attesting the quality of a scenario in high-fidelity simulation in healthcare. The main purpose of this study was to observe whether NASA Task Load Index for critical care-simulated scenarios, designed for residents, was consistent with the literature. The second purpose was to describe relationships between NASA Task Load Index, performance and generated stress during high-fidelity simulation. METHODS: All residents in anaesthesia and intensive care undergoing high-fidelity simulation were included. The primary endpoint was the task load generated by each scenario assessed by NASA Task Load Index. Based on the literature, the NASA Task Load Index scores between 39 and 61 were considered an acceptable level. Stress level (Visual Analogue Scale) and specific technical and non-technical skills performances (Team Emergency Assessment Measure) were also assessed. RESULTS: Totally 53 residents actively participated in 1 of 10 different scenarios, between June and December 2017. The median NASA Task Load Index score of scenarios was 61 [48-65]. Five scenarios generated acceptable task load levels. There was no association between the NASA Task Load Index score and technical or non-technical skills performance scores, but an association between NASA Task Load Index and the stress level (rho=4.7, P =.001) was observed. CONCLUSION: Simulation scenarios generate different task loads for residents; the task load was deemed acceptable for half of the scenarios. The NASA Task Load Index could be considered as a tool to assess the pedagogic adequacy of scenarios. Scenario and generated stress level, but not task load, can modify residents' performance during simulation. This should be considered when planning normative simulation.

Change in Sleep Quality of Residents the Night Before High-Fidelity Simulation: Results From a Prospective 1-Year National Survey.

OBJECTIVE: The stress level of participants in high-fidelity simulation stems from various factors but may result in anticipatory anxiety causing sleep disturbances during the night prior to simulation. The objective of this survey was to determine the change in sleep quality of residents during the night prior to the simulation. METHODS: The survey was proposed for 1 year to all residents at the beginning of the simulation, in 10 simulation centres. The questionnaire combined demographics and the Leeds Sleep Evaluation Questionnaire using visual analogue scales divided into 4 sleep qualitative domains. The primary outcome was the prevalence of sleep disturbance (>10 mm on 1 domain). Secondary outcomes were the prevalence of severe sleep disturbance (>25 mm), as well as qualitatively and quantitatively reported explanatory sleep parameters. RESULTS: Among respondents, 66% [95% CI: 63 to 69] of residents had more than 10 mm and 27% [95% CI: 24 to 30] had more than 25 mm of sleep disturbance. Residents with a sleep disturbance of more than 10 mm had fewer hours of sleep (6.4 [standard deviation=1.8] vs 7.3 [standard deviation=1.3], difference: -0.9 [95% CI: -1.1 to -0.7]; P < .0001), with a higher number of night-time awakenings (1.3 [standard deviation=1.5] vs 0.7 [standard deviation=0.9], difference: 0.6 [95% CI: 0.4 to 0.8]; P < .0001). CONCLUSION: Among residents participating in the simulation, a high prevalence of change in sleep quality during the night before the simulation was noted. Strategies to help residents achieve better sleep prior to simulation should be explored.

Effects of relaxing breathing paired with cardiac biofeedback on performance and relaxation during critical simulated situations: a prospective randomized controlled trial.

BACKGROUND: Active participation in high-fidelity simulation remains stressful for residents. Increased stress levels elicited during such simulation impacts performance. We tested whether relaxing breathing, paired or not with cardiac biofeedback, could lead to enhanced performance of residents during simulation. METHODS: This randomized pilot study involved the fifth-year anesthesiology and critical care residents who participated in high-fidelity at Lyon medical simulation center in 2019. Residents were randomized into three parallel interventions: relaxing breathing, relaxing breathing paired with cardiac biofeedback, and control. Each intervention was applied for five minutes immediately after the scenario briefing. The primary endpoint was the overall performance during the simulation rated by two blinded independent investigators. The secondary endpoints included component scores of overall performance and changes in psychological states. RESULTS: Thirty-four residents were included. Compared to the control group, residents in the relaxing breathing (+ 7%, 98.3% CI: 0.3 to 13.7, P = 0.013) and relaxing breathing paired with cardiac biofeedback (+ 8%, 98.3% CI: 0.82 to 14.81, P = 0.009) groups had a higher overall performance score. Following the interventions, compared to the control group, stress level was lower when participants had performed relaxing breathing alone (P = 0.029) or paired with biofeedback (P = 0.035). The internal relaxation level was higher in both the relaxing breathing alone (P = 0.016) and paired with biofeedback groups (P = 0.035). CONCLUSIONS: Performing five minutes of relaxing breathing before the scenario resulted in better overall simulation performance. These preliminary findings suggest that short breathing interventions are effective in improving performance during simulation. TRIAL REGISTRATION: The study protocol was retrospectively registered on clinicaltrials.gov ( NCT04141124 , 28/10/2019).

Impact of Ventilator-associated Pneumonia on Cerebrospinal Fluid Inflammation During Immunosuppression After Subarachnoid Hemorrhage: A Pilot Study.

INTRODUCTION: Brain injuries can cause systemic immunosuppression, which in turn can lead to infections that adversely affect the injured brain and worsen clinical outcomes. This study aimed to investigate whether systemic infection, such as ventilator-associated pneumonia (VAP), induce intracranial inflammation in patients with subarachnoid hemorrhage (SAH). METHODS: This prospective, observational study included 16 adults with SAH treated in the neuro-intensive care unit. Three paired cerebrospinal fluid samples (obtained from an external ventricular drain) and peripheral blood samples were obtained on days 1 to 3, 4 to 5, and 6 to 7 after SAH onset. Cell counts, cell phenotypes (monocyte HLA-DR, T regulatory cells, lymphocytes, and neutrophils), and inflammatory mediator levels were monitored. RESULTS: Six patients developed VAP in the context of systemic immunosuppression demonstrated by a reduction in monocyte HLA-DR expression, lymphopenia, increased percentages of circulating T regulatory cells, and increased proportions of immature and immunosuppressive neutrophil subsets. During VAP, there was de novo recruitment of leukocytes into the cerebrospinal fluid, preferentially neutrophils, which exacerbated intracranial inflammation. CONCLUSIONS: VAP increased intracranial inflammatory responses in patients with SAH despite the occurrence of systemic immunosuppression. A better understanding of cell trafficking and their pleiotropic functions in brain injury is needed to define the optimal strategies for preventing infections in patients with SAH.

Impact of a Digital Cognitive Aid on the Performance of Military Healthcare Teams During Critical Care Management in a Warfront Injury Situation: A Simulation Randomized Controlled Study.

INTRODUCTION: Initial healthcare delivery after warfront injury is unpredictably challenging for military forces. As preparatory training, healthcare providers use simulation to improve their performance in stressful critical situations. This study investigated whether a digital CA held by the team leader improved performance in simulated combat casualty care. METHODS: This randomized controlled trial was performed during a combat casualty training course for military physicians and nurses in France. Each pair of care providers completed 2 scenarios randomized to be undertaken either with or without a digital CA. The primary end point was the technical performance evaluated from a video recording by 2 independent raters using a pre-established score grid (up to 100%) according to military protocols. The secondary end point was the nontechnical performance (TEAM scale, maximum: 54 points). RESULTS: Thirty-six pairs of participants were included. Use of the digital CA improved both technical (74% vs 53%, P < 0.001) and nontechnical (42 vs 32, P < 0.001) performance. CONCLUSIONS: The digital CA improved technical and nontechnical performance during training of medical care for military combat casualties. Use of a dedicated digital CA might improve care in a combat environment. STUDY TYPE: This study is a randomized controlled trial.

Short- and long-term prognosis of acute critically ill patients with systemic rheumatic diseases: A retrospective multicentre study.

ABSTRACT: Patients with systemic rheumatic disease (SRD) share the risks of multi-organ flare-up, cardiovascular diseases, and immunosuppression. Such situations can lead to an acute critical illness. The present study describes the clinical features of SRD patients admitted to the intensive care unit (ICU) and their short- and long- term mortality.We performed a multicentre retrospective study in 10 French ICU in Lyon, France. Inclusion criteria were SRD diagnosis and admission for an acute organ failure. The primary endpoint was ICU mortality.A total of 271 patients were included. SRD included systemic lupus erythematosus (23.2% of included patients), vasculitis (10.7%), systemic sclerosis (10.7%), idiopathic inflammatory myopathy (6.3%), and other connective tissue disorders (rheumatoid arthritis, Sjögren and Sharp syndromes; 50.9%). Initial organ failure(s) were shock (43.5% of included patients), acute kidney injury (30.5%), and acute respiratory failure (23.2%). The cause(s) of ICU admission included sepsis (61.6%), cardiovascular events (33.9%), SRD-flare up (32.8%), and decompensations related to comorbidities (28%). The ICU mortality reached 14.3%. The factors associated with ICU mortality were chronic cardiac failure, invasive ventilation and admission in ICU for another reason than sepsis or SRD flare-up. The median follow-up after ICU discharge was 33.6 months. During follow-up, 109 patients died. The factors associated with long-term mortality included age, Charlson comorbidity index, and ICU admission for sepsis or SRD flare-up.The ICU mortality of patients with SRD was low. Sepsis was the first cause of admission. Cardiovascular events and comorbidities negatively impacted ICU mortality. Admission for sepsis or SRD flare-up exerted a negative effect on the long-term outcome.

Effect of motor imagery and actual practice on learning professional medical skills.

BACKGROUND: The peripheral venous catheter is the most frequently used medical device in hospital care to administer intravenous treatment or to take blood samples by introducing a catheter into a vein. The aim of this study was to examine the effect of motor imagery associated with actual training on the learning of peripheral venous catheter insertion into a simulated venous system. METHOD: This was a prospective monocentre study in 3rd year medical students. Forty medical students were assigned to the experimental group (n = 20) performing both real practice and motor imagery of peripheral venous catheter insertion or to the control group (n = 20) trained through real practice only. We also recruited a reference group of 20 professional nurses defining the benchmark for a target performance. RESULTS: The experimental group learned the peripheral venous catheter insertion faster than the control group in the beginning of learning phase (p < 0.001), reaching the expected level after 4 sessions (p = .87) whereas the control group needed 5 sessions to reach the same level (p = .88). Both groups were at the same level at the end of the scheduled training. CONCLUSIONS: Therefore, motor imagery improved professional motor skills learning, and limited the time needed to reach the expected level. Motor imagery may strengthen technical medical skill learning.

Ventilation Management and Outcomes for Subjects With Neuromuscular Disorders Admitted to ICUs With Acute Respiratory Failure.

BACKGROUND: Patients with neuromuscular disorders (NMD) share the risk of acute respiratory failure (ARF) leading to ICU admissions. Noninvasive ventilation (NIV) is often proposed as an alternative to invasive ventilation. This study describes clinical features, ventilation management, and outcomes of subjects with NMD admitted to ICU and managed for ARF. METHODS: We performed a multicenter retrospective study in 7 adult ICUs in the Auvergne-Rhone-Alpes area in France involving subjects with NMD admitted to the ICU for ARF. The primary end point was ICU mortality. Secondary end points were NIV failure, weaning from invasive ventilation, and long-term mortality. We hypothesized a poorer outcome in the case of bulbar musculature involvement. RESULTS: A total of 242 subjects were included; 142 subjects had nonhereditary NMD (58.7%), and 100 had hereditary NMD (41.3%). Eleven subjects had home ventilation through a tracheostomy. While 112 were intubated at admission, 119 initially underwent NIV. NIV was successful in avoiding orotracheal intubation in 78 subjects (65.5%). ICU mortality was 13.6%. Factors associated with ICU mortality were nonhereditary NMD and requirement for invasive ventilation. The involvement of bulbar musculature in ARF and hereditary NMD were associated with NIV failure. After a median follow-up of 1.2 y, 53 of 209 subjects had died. CONCLUSIONS: The ICU mortality of NMD subjects with ARF was low, with no impact of bulbar muscles involvement. NIV was proposed for approximately half of the subjects, and it was more effective when ARF was not attributed to bulbar musculature involvement. The long-term outcome was good.

Stress Management Training Improves Overall Performance during Critical Simulated Situations: A Prospective Randomized Controlled Trial.

BACKGROUND: High-fidelity simulation improves participant learning through immersive participation in a stressful situation. Stress management training might help participants to improve performance. The hypothesis of this work was that Tactics to Optimize the Potential, a stress management program, could improve resident performance during simulation. METHODS: Residents participating in high-fidelity simulation were randomized into two parallel arms (Tactics to Optimize the Potential or control) and actively participated in one scenario. Only residents from the Tactics to Optimize the Potential group received specific training a few weeks before simulation and a 5-min reactivation just before beginning the scenario. The primary endpoint was the overall performance during simulation measured as a composite score (from 0 to 100) combining a specific clinical score with two nontechnical scores (the Ottawa Global Rating Scale and the Team Emergency Assessment Measure scores) rated for each resident by four blinded independent investigators. Secondary endpoints included stress level, as assessed by the Visual Analogue Scale during simulation. RESULTS: Of the 134 residents randomized, 128 were included in the analysis. The overall performance (mean ± SD) was higher in the Tactics to Optimize the Potential group (59 ± 10) as compared with controls ([54 ± 10], difference, 5 [95% CI, 1 to 9]; P = 0.010; effect size, 0.50 [95% CI, 0.16 to 0.91]). After specific preparation, the median Visual Analogue Scale was 17% lower in the Tactics to Optimize the Potential group (52 [42 to 64]) than in the control group (63 [50 to 73]; difference, -10 [95% CI, -16 to -3]; P = 0.005; effect size, 0.44 [95% CI, 0.26 to 0.59]. CONCLUSIONS: Residents coping with simulated critical situations who have been trained with Tactics to Optimize the Potential showed better overall performance and a decrease in stress level during high-fidelity simulation. The benefits of this stress management training may be explored in actual clinical settings, where a 5-min Tactics to Optimize the Potential reactivation is feasible prior to delivering a specific intervention.

Use of a Digital Cognitive Aid in the Early Management of Simulated War Wounds in a Combat Environment, a Randomized Trial.

INTRODUCTION: The French army has implemented an algorithm based on the acronym "MARCHE RYAN," each letter standing for a key action to complete in order to help first care providers during emergency casualty care. On the battlefield, the risk of error is increased, and the use of cognitive aids (CAs) might be helpful to avoid distraction. We investigated the effect of using a digital CA (MAX, for Medical Assistance eXpert) by combat casualty care providers on their technical and nontechnical performances during the early management of simulated war wounds, compared to their memory and training alone. MATERIALS AND METHODS: We conducted a randomized, controlled, unblinded study between July 2016 and February 2017. This study was approved by the Ethics Committee of the Ethical Board of Desgenettes Army Training Hospital (14.06.2017 n°385) and was registered on clinicaltrials.gov (NCT03483727). It took place during medicalization training in hostile environment ("MEDICHOS") in Chamonix Mont-Blanc and in the first aid training center in La Valbonne military base (France). Each participant had to deal with two different scenarios, one with MAX (MAX+) and the other without (MAX-). Scenarios were held using either high-fidelity patient simulators or actors as wounded patients. The primary outcome was participants' technical performance rated as their adherence to the MARCHE RYAN procedure (maximum 100%). The secondary outcome was the nontechnical performance according to the Ottawa crisis resource management Global Rating Scale (maximum 42). RESULTS: Technical performance was significantly higher in the MAX+ scenarios (70.60 IQR [63.70-73.56] than in the MAX- scenarios (56.25 IQR [52.88-62.09], p = 0.002). The Ottawa scores were significantly higher in the MAX+ scenarios (31.50 IQR [29.50-33.75]) than in the MAX- scenarios (29.50 IQR [24.50-32.00], p = 0.031). CONCLUSIONS: The use of a digital CA by combat casualty care providers improved technical and nontechnical performances during field training of simulated crises. Following recommendations on the design and use of CA, regular team training would improve fluidity in the use and acceptance of an aid, by a highly drilled professional corporation with a strong culture of leadership. Digital CA should be tested at a larger scale in order to validate their contribution to real combat casualty care.

Frailty In Patients Undergoing Vascular Surgery: A Narrative Review Of Current Evidence.

Frailty is presumably associated with an elevated risk of postoperative mortality and adverse outcome in vascular surgery patients. The aim of our review was to identify possible methods for risk assessment and prehabilitation in order to improve recovery and postoperative outcome. The literature search was performed via PubMed, Embase, OvidSP, and the Cochrane Library. We collected papers published in peer-reviewed journals between 2001 and 2018. The selection criterion was the relationship between vascular surgery, frailty and postoperative outcome or mortality. A total number of 52 publications were included. Frailty increases the risk of non-home discharge independently of presence or absence of postoperative complications and it is related to a higher 30-day mortality and major morbidity. The modified Frailty Index showed significant association with elevated risk for post-interventional stroke, myocardial infarction, prolonged in-hospital stays and higher readmission rates. When adjusted for comorbidity and surgery type, frailty seems to impact medium-term survival (within 2 years). Preoperative physical exercising, avoidance of hypalbuminemia, psychological and cognitive training, maintenance of muscle strength, adequate perioperative nutrition, and management of smoking behaviours are leading to a reduced length of stay and a decreased incidence of readmission rate, thus improving the effectiveness of early rehabilitation. Pre-frailty is a dynamically changing state of the patient, capable of deteriorating or improving over time. With goal-directed preoperative interventions, the decline can be prevented.

[Simulation of difficult airway management for residents: prospective comparative study]. / Simulação de manejo de via aérea difícil para residentes: estudo comparativo prospectivo.

BACKGROUND AND OBJECTIVES: Procedural simulation training for difficult airway management offers acquisition opportunities. The hypothesis was that 3 hours of procedural simulation training for difficult airway management improves: acquisition, behavior, and patient outcomes as reported 6 months later. METHODS: This prospective comparative study took place in two medical universities. Second-year residents of anesthesiology and intensive care from one region participated in 3h procedural simulation (intervention group). No intervention was scheduled for their peers from the other region (control). Prior to simulation and 6 months later, residents filled-out the same self-assessment form collecting experience with different devices. The control group filled-out the same forms simultaneously. The primary endpoint was the frequency of use of each difficult airway management device within groups at 6 months. Secondary endpoints included modifications of knowledge, skills, and patient outcomes with each device at 6 months. Intervention cost assessment was provided. RESULTS: 44 residents were included in the intervention group and 16 in the control group. No significant difference was observed for the primary endpoint. In the intervention group, improvement of knowledge and skills was observed at 6 months for each device, and improvement of patient outcomes was observed with the use of malleable intubation stylet and Eschmann introducer. No such improvement was observed in the control group. Estimated intervention cost was 406€ per resident. CONCLUSIONS: A 3h procedural simulation training for difficult airway management did not improve the frequency of use of devices at 6 months by residents. However, other positive effects suggest exploring the best ratio of time/acquisition efficiency with difficult airway management simulation. CLINICALTRIALS. GOV IDENTIFIER: NCT02470195.

Resumo Justificativa e objetivos O treinamento em simulação para o manejo de via aérea difícil oferece oportunidades de aprendizagem. A hipótese foi que um treinamento em simulação de procedimentos de três horas, para o manejo de via aérea difícil, melhoraria o aprendizado, o comportamento e os resultados dos pacientes, conforme relatado seis meses após o treinamento. Métodos Este estudo comparativo prospectivo foi realizado em duas universidades médicas. Residentes do segundo ano de anestesiologia e terapia intensiva de uma região participaram de um curso de três horas em simulação de procedimentos (grupo intervenção). Nenhuma intervenção foi programada para seus pares da outra região (grupo controle). Antes da simulação e seis meses após, os residentes preencheram a mesma ficha de autoavaliação sobre sua experiência com diferentes dispositivos. O grupo controle preencheu os mesmos formulários simultaneamente. O desfecho primário foi a frequência de uso de cada dispositivo para o manejo de via aérea difícil dentro dos grupos aos seis meses. Os pontos de corte secundários incluíram modificações em relação ao conhecimento, às habilidades e aos resultados dos pacientes com cada dispositivo aos seis meses. A avaliação do custo da intervenção foi registrada. Resultados Foram incluídos no grupo intervenção 44 residentes e 16 no grupo controle. Nenhuma diferença significativa foi observada para o ponto de corte primário. No grupo intervenção, a melhoria do conhecimento e das habilidades foi observada aos seis meses para cada dispositivo e a melhoria dos desfechos dos pacientes foi analisada com o uso de estilete maleável e do introdutor de Eschmann para intubação. Nenhuma melhoria foi observada no grupo controle. O custo da intervenção estimado foi de 406€ por residente. Conclusões Um treinamento simulado de três horas para o manejo de via aérea difícil não melhorou a frequência do uso de dispositivos pelos residentes aos seis meses. No entanto, outros efeitos positivos sugerem a exploração da melhor relação tempo/eficiência de aquisição de conhecimento com a simulação do manejo de via aérea difícil.
