Setting a direction for continuing professional development in anesthesiology: A synthesis of the outcome from an Utstein style meeting.

BACKGROUND: An Utstein style meeting of key stakeholders from the existing collaboration surrounding post-graduate training was arranged to set a direction for continuing professional development (CPD) of anesthesiologists in Denmark. A 2-day meeting was planned to guide discussions about competencies in anesthesiology, facilitate the development of a blueprint for a portfolio-based CPD program and provide examples of how a portfolio can be used in practice. METHODS: The meeting agenda was based on an adaptation of Kern's six-step approach to curriculum development. Twenty-four participants from the university hospitals in Denmark were invited. Prior to the meeting participants were informed of the objectives and the Utstein style process. RESULTS: Participants acknowledged a need for a more structured approach to CPD, preferably within the current organizational set up at the departmental level, and with a portfolio-based, individualized curriculum. It was recognized that CPD should contain an array of possibilities to accommodate needs and wants of both the individual and the department. It was emphasized that, while anesthesiologists are used to give feedback to trainees, many are less familiar in providing the same to peers, and psychological safety was identified as a prerequisite to support a culture where specialists can reflect openly on each other's performance. CONCLUSION: The results provide an insight into the attitudes, opportunities, and challenges of anesthesiologists in relation to continuing professional development in Denmark. Generally, participant suggestions are in line with the shift in medical education toward workplace-based learning, feedback and lifelong learning.

Long-term experiences of being a simulation-educator: A multinational interview study.

The long-term reactions, experiences and reflections of simulation educators have not been explored. In a semistructured, exploratory interview study, the experiences of simulation educators in either Advanced Life Support (ALS) or Crisis Resource Management (CRM) courses in Denmark, Norway and the USA were analyzed. Three overarching themes were identified: (1) general reflections on simulation-based teaching, (2) transfer of knowledge and skills from the simulation setting to clinical settings and (3) more overarching transformations in simulation educators, simulation participants, and the healthcare system. Where ALS was deemed as high on the efficiency dimension of learning, CRM courses were described as high on the innovation dimension. General reflections, transfer and transformations described were related to differences in course principles. The results are relevant for career planning, faculty development and understanding simulation as social practice.

Modifications of the National Early Warning Score for patients with chronic respiratory disease.

BACKGROUND: The National Early Warning Score (NEWS) uses physiological variables to detect deterioration in hospitalized patients. However, patients with chronic respiratory disease may have abnormal variables not requiring interventions. We studied how the Capital Region of Denmark NEWS Override System (CROS), the Chronic Respiratory Early Warning Score (CREWS) and the Salford NEWS (S-NEWS) affected NEWS total scores and NEWS performance. METHODS: In an observational study, we included patients with chronic respiratory disease. The frequency of use of CROS and the NEWS total score changes caused by CROS, CREWS and S-NEWS were described. NEWS, CROS, CREWS and S-NEWS were compared using 48-h mortality and intensive care unit (ICU) admission within 48 h as outcomes. RESULTS: We studied 11,266 patients during 25,978 admissions; the use of CROS lowered NEWS total scores in 40% of included patients. CROS, CREWS and S-NEWS had lower sensitivities than NEWS for 48-h mortality and ICU admission. Specificities and PPV were higher. CROS, CREWS and S-NEWS downgraded, respectively, 51.5%, 44.9% and 32.8% of the NEWS total scores from the 'mandatory doctor presence' and 'immediate doctor presence and specialist consultation' total score intervals to lower intervals. CONCLUSION: Capital Region of Denmark NEWS Override System was frequently used in patients with chronic respiratory disease. CROS, CREWS and S-NEWS reduced sensitivity for 48-h mortality and ICU admission. Using the methodology prevalent in the NEWS literature, we cannot conclude on the safety of these systems. Future prospective studies should investigate the balance between detection rate and alarm fatigue of different systems, or use controlled designs and patient-centred outcomes.

Evaluating structured assessment of anaesthesiologists' non-technical skills.

BACKGROUND: Non-technical skills (NTS) are essential for safe and efficient anaesthesia. Assessment instruments with appropriate validity evidence can be used to ensure that anaesthesiologists possess the NTS necessary to deliver high-standard patient care. The aims were to collect validity evidence using a contemporary validity framework for the assessment instrument Anaesthesiologists' Non-Technical Skills in Denmark (ANTSdk) regarding response process and internal structure (including reliability), and to investigate the effect of rater training on these properties. METHODS: An explorative study was undertaken at the Danish Institute for Medical Simulation, Copenhagen, Denmark. In a 1-day session, using ANTSdk, a convenience sample of 19 anaesthesiologists rated trainee anaesthesiologists' NTS in nine video-recorded simulation scenarios before and after a 3-h training session. RESULTS: Response process evidence: participants considered ANTSdk useful and feasible for NTS assessment. Internal structure evidence: inter-rater reliability (single measures) largely expressed substantial agreement (ICC ≥ 0.55 and ICC ≥ 0.60 for pre- and post-training ratings respectively). Strong internal consistency of ratings was found (Spearman's correlation coefficient ≥ 0.82). Accuracy of participants' ratings compared with reference ratings (± 1 scale point) was notable (76% and 78% for pre- and post-training ratings, respectively). The results indicate that the elements 'Demonstrating self-awareness', 'Reassessing decisions', 'Assessing competencies', and 'Supporting others' need more attention in future rater training. CONCLUSION: The validity evidence collected on content, response process, and internal structure, suggests that ANTSdk is easy to use on video-recorded simulation scenarios, indicating that ANTSdk is a feasible instrument for NTS assessment during anaesthesia training.

Exploring the relationship between anaesthesiologists' non-technical and technical skills.

BACKGROUND: A combination of non-technical skills (NTS) and technical skills (TS) is crucial for anaesthetic patient management. However, a deeper understanding of the relationship between these two skills remains to be explored. We investigated the characteristics of trainee anaesthesiologists' NTS and TS in a simulated unexpected difficult airway management scenario. METHODS: A mixed-method approach was used to explore the relationship between NTS and TS in 25 videos of 2nd year trainee anaesthesiologists managing a simulated difficult airway scenario. The videos were assessed using the customised version of the Anaesthetists' Non-Technical Skills System, ANTSdk, and an adapted TS checklist for calculating the correlation between NTS and TS. Written descriptions of the observed NTS were analysed using directed content analysis. RESULTS: The correlation between the NTS and the TS ratings was 0.106 (two-tailed significance of 0.613). Inter-rater reliability was substantial. Themes characterising good NTS included a systematic approach, planning and communicating decisions as well as responding to the evolving situation. A list of desirable, concrete NTS for the specific airway management situation was generated. CONCLUSION: This study illustrates that anaesthesiologist trainees' NTS and TS were not correlated in this setting, but rather intertwined and how the interplay of NTS and TS can impact patient management. Themes describing the characteristics of NTS and a list of desirable, concrete NTS were developed to aid the understanding, training and use of NTS.

Multidisciplinary team training reduces the decision-to-delivery interval for emergency Caesarean section.

BACKGROUND: Emergency Caesarean section is performed when the life of the pregnant woman and/or the foetus is considered at risk. A 30-min standard for the decision-to-delivery interval (DDI) is a common practice and is supported by national organisations including The Danish Society of Obstetrics and Gynaecology. Danish obstetric departments report the DDI to a national database. A national arbitrarily set standard recommends that 95% of ECSs should be achieved within the 30-min DDI standard. In 2011, 34.4% of ECSs, performed at our hospital, were achieved within the 30-min time frame. This study aims to evaluate the effect of a simulation-based team training programme on the proportion of ECSs achieved within a 30-min time frame. METHOD: We performed an interventional before-and-after study. We evaluated a total of one hundred 30-min ECSs before and after the intervention. The primary outcome of interest was the proportion of 30-min ECSs achieved within a 30-min time frame. RESULTS: A total of 20 team training courses were held during May/June 2013. These courses trained 239 of 252 team members (comprised of: 36 obstetricians, 45 scrub nurses, 83 midwives, 38 anaesthesiologists, 37 nurse anaesthetists) in handling of 30-min ECS. This corresponds to 95% of staff. The proportion of 30-min ECSs achieved within a 30-min time frame was higher after team training (87.5%, 95% CI 79.2-93.4%) compared with before training (74.0%, 95% CI 64.0-82.4%) (P = 0.017). CONCLUSION: Team training may contribute positively to an increase in the proportion of ECSs achieved within a 30-min time frame.

Efficacy of simulation-based trauma team training of non-technical skills. A systematic review.

Trauma resuscitation is a complex situation, and most organisations have multi-professional trauma teams. Non-technical skills are challenged during trauma resuscitation, and they play an important role in the prevention of critical incidents. Simulation-based training of these is recommended. Our research question was: Does simulation-based trauma team training of non-technical skills have effect on reaction, learning, behaviour or patient outcome? The authors searched PubMed, EMBASE and the Cochrane Library and found 13 studies eligible for analysis. We described and compared the educational interventions and the evaluations of effect according to the four Kirkpatrick levels: reaction, learning (knowledge, skills, attitudes), behaviour (in a clinical setting) and patient outcome. No studies were randomised, controlled and blinded, resulting in a moderate to high risk of bias. The multi-professional trauma teams had positive reactions to simulation-based training of non-technical skills. Knowledge and skills improved in all studies evaluating the effect on learning. Three studies found improvements in team performance (behaviour) in the clinical setting. One of these found difficulties in maintaining these skills. Two studies evaluated on patient outcome, of which none showed improvements in mortality, complication rate or duration of hospitalisation. A significant effect on learning was found after simulation-based training of the multi-professional trauma team in non-technical skills. Three studies demonstrated significantly increased clinical team performance. No effect on patient outcome was found. All studies had a moderate to high risk of bias. More comprehensive randomised studies are needed to evaluate the effect on patient outcome.

Assessing Nurse Anaesthetists' Non-Technical Skills in the operating room.

BACKGROUND: Incident reporting and fieldwork in operating rooms have shown that some of the errors that arise in anaesthesia relate to inadequate use of non-technical skills. To provide a tool for training and feedback on nurse anaesthetists' non-technical skills, this study aimed to adapt the Anaesthetists' Non-Technical Skills (ANTS) as a behavioural marker system for the formative assessment of nurse anaesthetists' non-technical skills in the operating room. METHODS: A qualitative approach with focus group interviews was used to identify the non-technical skills of nurse anaesthetists in the operating room. The interview data were transcribed verbatim. Directed content analysis was used to code and sort data deductively into the ANTS categories: task management, team working, situation awareness and decision making. The prototype named Nurse Anaesthetists' Non-Technical Skills (N-ANTS) was presented and discussed in a group of subject matter experts to ensure face validity. RESULTS: The N-ANTS system consists of the same four categories as ANTS and 15 underlying elements. Three to five good and poor behavioural markers for each element were identified. The headings and definitions of the categories and elements were adjusted to encompass the behavioural markers in N-ANTS. The differences that emerged mainly reflected statements regarding the establishment of role, competence, and task delegation. CONCLUSION: A behavioural marker system, N-ANTS, for nurse anaesthetists was adapted from a behavioural marker system, ANTS, for anaesthesiologists.

Handover of patients: a topical review of ambulance crew to emergency department handover.

Handover has major implications for patient care. The handover process between ambulance and emergency department (ED) staff has been sparsely investigated. The purpose of this paper is, based on a literature review, to identify and elaborate on the major factors influencing the ambulance to ED handover, and to bring suggestions on how to optimize this process. A literature search on handovers to EDs was performed in PubMed, Embase, Web of Science and Cochrane databases. A total of 18 papers were included. Issues regarding transfer of information are highlighted. Newer studies suggest that implementing a structured handover format holds the possibilities for improving the process. Electronic equipment could play a part in reducing problems. Cultural and organizational factors impact the process in different ways. The professions perceive the value and quality of information given differently. Giving and taking over responsibility is an important issue. The handover of patients to the ED has the potential to be improved. Cultural issues and a lack of professional recognition of handover importance need to be approached. Multidisciplinary training in combination with a structured tool may have a potential for changing the culture and improving handover.

The role of patient simulation and incident reporting in the development and evaluation of medical devices and the training of their users.

We describe how simulation and incident reporting can be used in combination to make the interaction between people, (medical) technology and organisation safer for patients and users. We provide the background rationale for our conceptual ideas and apply the concepts to the analysis of an actual incident report. Simulation can serve as a laboratory to analyse such cases and to create relevant and effective training scenarios based on such analyses. We will describe a methodological framework for analysing simulation scenarios in a way that allows discovering and discussing mismatches between conceptual models of the device design and mental models users hold about the device and its use. We further describe how incident reporting systems can be used as one source of data to conduct the necessary needs analyses - both for training and further needs for closer analysis of specific devices or some of their special features or modes during usability analyses.

Implementation of team training in medical education in Denmark.

In the field of medicine, team training aiming at improving team skills such as leadership, communication, co-operation, and followership at the individual and the team level seems to reduce risk of serious events and therefore increase patient safety. The preferred educational method for this type of training is simulation. Team training is not, however, used routinely in the hospital. In this paper, we describe a framework for the development of a team training course based on need assessment, learning objectives, educational methods including full-scale simulation and evaluations strategies. The use of this framework is illustrated by the present multiprofessional team training in advanced cardiac life support, trauma team training and neonatal resuscitation in Denmark. The challenges of addressing all aspects of team skills, the education of the facilitators, and establishment of evaluation strategies to document the effect of the different types of training on patient safety are discussed.

Qualitative analysis of unanticipated difficult airway management.

BACKGROUND: Unanticipated difficult airway management (DAM) is a major challenge for the anaesthesiologist and is associated with a risk of severe patient damage. We analysed 24 cases of unanticipated DAM for actual case management and anaesthesiologists knowledge, technical and non-technical skills. Anaesthesiologists' opinions, as well as environmental factors of importance for DAM proficiency, were also assessed. METHODS: Departments of Anaesthesiology in three Copenhagen University Hospitals participated in a prospective study of unanticipated DAM. Anaesthesiologists recorded the details of the cases on a data sheet. Qualitative data were collected in a semi-structured interview if the value of the Intubation Difficulty Score (IDS) was more than five, if the value of the visual analogue scale score for mask ventilation was more than five or in the case of a registered complication. Transcripts were theme analysed independently by two analysts. Data sheets and interviews were used in the final evaluation. RESULTS: All 24 cases concerned difficult tracheal intubation, and this was associated with difficult mask ventilation on four occasions. Management in three cases demonstrated strict adherence to a DAM practice guideline. Anaesthesiologists lacked standards for DAM. Inadequate knowledge, training and training facilities were documented. Sudden re-allocation of personnel and change of anaesthetic technique were potential risk factors for DAM. Insufficient airway assessment, insufficient patient information and registration of difficulties were demonstrated. Ethical issues were raised concerning the use of patients for skills practice. CONCLUSIONS: Both personal and system failures resulted in unanticipated DAM. There was insufficient knowledge of DAM and anaesthesiologists lacked DAM training. Standards for DAM and curricula for continuing education in DAM are needed.

Residents lack knowledge and practical skills in handling the difficult airway.

BACKGROUND: Full-scale simulators have been developed in anaesthesia. We aimed at assessing Danish anaesthesia residents' knowledge and management of a standardized difficult airway situation in an advanced airway simulator. The reliability of the assessment was also determined. METHODS: Thirty-six residents answered a questionnaire testing their knowledge on difficult airway management and practice patterns. Secondly, all residents attempted management of a standardized 'cannot ventilate, cannot intubate' airway scenario. Three observers independently assessed a video recording of the performance. RESULTS: Only 17% of the residents passed the written test. Ninety-seven per cent stated that they had difficulties recalling the American Society of Anesthesiologists'(ASA) difficult airway algorithm and 53% did not know how to oxygenate through the cricothyroid membrane. Seventeen per cent had previously been involved in emergency situations with severe complications due to insufficient airway management. In the scenario 75% of the residents established ventilation using a laryngeal mask airway. After establishing ventilation, 26% would continue with surgery without a definitive airway, despite the risk of aspiration. Analysis of the interobserver agreement showed good (Kappa = 0.63) to excellent (Kappa = 0.78) consistency for objective parameters in the scoring scheme. Inter-observer reliability was satisfactory (R = 0.43) for trained Crisis Resource Management evaluators. CONCLUSIONS: Theoretical and practical education in difficult airway management needs to be improved among Danish anaesthesia residents. Simulator assessment should only be performed using well-defined objective parameters and trained assessors.

Implementation of a formal in-training assessment programme in anaesthesiology and preliminary results of acceptability.

BACKGROUND: A new reform on postgraduate education in Denmark requires a formal in-training assessment in all specialties. The aim of this study was to survey the implementation and acceptability of the first example of a nation-wide in-training assessment programme for first-year trainees in anaesthesiology developed by a working group under the Danish Society of Anaesthesiology and Intensive Care Medicine. METHODS: A questionnaire about the implementation of the programme in practice and the characteristics of the trainees was sent to the educational responsible consultant (ERC) in each of the 26 anaesthetic departments in the country with first-year trainees in anaesthesiology. Standard evaluations of the assessment programme were regularly collected from trainees. RESULTS: Twenty-five (96%) departments returned the questionnaire. In total the departments reported on 100 trainees and 83 of these had been enrolled in the programme. Thirteen departments reported in total on 27 trainees who had completed their first year of training and these departments had applied a median 21 (range 17-21) of the 21 tests included in the entire programme. Time constraints and resistance among senior clinicians were the most frequently cited barriers to implementation. Evaluations from trainees showed a generally positive attitude towards most of the programme. They especially praised the programme's effect on structuring training and having a positive effect on learning. CONCLUSION: The in-training assessment programme has been widely implemented across the country. The majority of the programme was acceptable to trainees and had a positive effect on structuring training and on fostering learning.

Pharmacokinetics and pharmacodynamics of mivacurium in patients phenotypically heterozygous for the usual and atypical plasma cholinesterase variants (UA).

BACKGROUND: Mivacurium is hydrolyzed by plasma cholinesterase (pChe). The purpose of this study was to evaluate the pharmacodynamics and the pharmacokinetics of the three isomers of mivacurium in patients phenotypically heterozygous for the usual and the atypical pChe variant (UA). METHODS: Thirty-two patients were included in a dose-response study, in which the patients received one of four doses of mivacurium. An additional bolus dose of mivacurium, to a total of 0.1 mg kg-1, was given followed by a continuous infusion adjusted to maintain 91-99% neuromuscular block. The times to different levels of recovery following the infusion were measured using mechanomyography and train-of-four (TOF) nerve stimulation. Twelve of the patients with an estimated duration of anaesthesia of more than 90 min were (randomly) selected for the pharmacokinetic part of the study. Venous samples were taken for determination of the three isomers of mivacurium. These results were compared with results from a previous study in phenotypically normal patients (UU). RESULTS: The estimated ED50 and ED95 were 24 and 69 microg kg-1, respectively. The median (range) infusion rate was 3.7 microg kg-1 min-1 (1.2-2.9) and the time to a TOF ratio of 0.7 was 29.8 min (16.1-44.8). The median clearances of the cis-cis, cis-trans and trans-trans isomers were 3.7, 29 and 28 ml kg-1 min-1, respectively. The elimination half-lives of the isomers were 45, 6.7 and 6.3 min, respectively. CONCLUSION: In patients heterozygous for the usual and the atypical variant (UA), the potency of mivacurium is higher, the infusion requirements lower and the rate of spontaneous recovery prolonged, compared with phenotypically normal patients. The clearances of the active isomers are significantly lower and the elimination half-lives longer in heterozygous patients than in phenotypically normal patients (UU). The pharmacokinetics of the inactive cis-cis isomer was not affected.

A feasibility study comparing checklists and global rating forms to assess resident performance in clinical skills.

This study evaluated the feasibility of two different scoring forms for assessing the clinical performance of residents in anaesthesiology. One of the forms had a checklist format including task-specific items and the other was a global rating form with general dimensions of competence including 'clinical skills', 'communication skills' and 'knowledge'. Thirty-two clinicians representing 25 (83%) of the 30 training hospitals in the country participated in the study. The clinicians were randomized into two groups, each of which used one of the scoring formats to assess a resident's performance in four simulated clinical scenarios on videotape. Clinicians' opinions about the appropriateness of the scoring forms were rated on a scale of 1-5. The checklist format was rated significantly higher compared with the global rating form (mean 4.6, 0.5 vs. mean 3.5, 1.4, p < 0.001). The inter-rater agreement regarding pass/fail decisions was poor irrespective of the scoring form used. This was explained by clinicians' leniency as assessors rather than by lack of vigilance in the observations or disagreements on standards for good performance.

Embracing the new paradigm of assessment in residency training: an assessment programme for first-year residency training in anaesthesiology.

Assessment of clinical competence is facing a paradigm shift in more than one sense. The shift relates to test content, which increasingly covers a broader spectrum of competences than mere medical expertise, and to test methods, with an increasing focus on testing performance in realistic settings. Also there is a shift in the concept of assessment in that instruction and assessment are no longer seen as being separate in time and purpose, but as integral parts of the learning process. The nature of the new paradigm for assessment is well described but the challenge to programme directors is to specify the evaluation situations and develop appropriate methods. This paper describes the intrinsic rational validation process in outlining an assessment programme for first-year anaesthesiology residency training according to the new paradigm. The applicability to other residency programmes and higher-level training in anaesthesiology is discussed.

Remifentanil vs. alfentanil for direct laryngoscopy: a randomized study comparing two total intravenous anaesthesia techniques. TIVA for direct laryngoscopy.

The ideal anaesthesia for direct laryngoscopy is profound and yet brief. The present study sought to determine whether a new anaesthetic technique based on infusion of the ultra short-acting opioid remifentanil was superior to our routine alfentanil multiple-dose technique in terms of haemodynamic stability, stress responses and recovery. A total of 58 patients were randomized to receive propofol and either remifentanil or alfentanil as part of a total intravenous anaesthesia. In the remifentanil group, systolic blood pressure during anaesthesia remained significantly lower than baseline values, while it increased significantly in the alfentanil group. None of the patients receiving remifentanil showed stress responses (hypertension, tachycardia, somatic or autonomic responses), compared to 22 patients (79%) in the alfentanil group (P < 0.0001). In the remifentanil group, hypotension or bradycardia requiring intervention arose in 5 (18%) and 3 patients (11%); neither response was seen in the alfentanil group. The period from the end of propofol infusion until extubation was 5 min longer in the remifentanil group (P < 0.0001), whereas the time from extubation until discharge was similar in the two groups. Thus, neither technique showed sufficient haemodynamic stability, and further studies are needed to determine optimal dosages of propofol and opioid.

Consultants' opinion on a new practice-based assessment programme for first-year residents in anaesthesiology.

BACKGROUND: Assessment in postgraduate education is moving towards using a broad spectrum of practice-based assessment methods. This approach was recently introduced in first-year residency in anaesthesiology in Denmark. The new assessment programme covers: clinical skills, communication skills, organizational skills and collaborative skills, scholarly proficiencies and professionalism. Eighteen out of a total of 21 assessment instruments were used for pass/fail decisions. The aim of this study was to survey consultants' opinions of the programme in terms of the representativeness of competencies tested, the suitability of the programme as a basis for pass/fail decisions and the relevance and sufficiency of the content of the different assessment instruments. METHODS: A description of the assessment programme and a questionnaire were sent to all consultants of anaesthesiology in Denmark. The questionnaire consisted of items, to be answered on a five-point scale, asking the consultants' opinions about representativeness, suitability and content of the programme. RESULTS: The response rate was 251/382 (66%). More than 75% of the respondents agreed that the assessment programme offered adequate coverage of the competencies of a first-year resident and was appropriate for making pass/fail decisions. There was strong agreement that the content of the 18 tests used for pass/fail decisions was relevant and sufficient for pass/fail decisions. CONCLUSION: Judging from the consultants' opinions, the assessment programme for first-year residency in anaesthesiology appears to be appropriate regarding the range of competencies assessed, the appropriateness as a basis for pass/fail decisions, and regarding the content of the tests used for pass/fail decisions. Further studies are needed to assess the feasibility and acceptability of the programme in practice.
