Development of objective performance metrics for ultrasound-guided internal jugular vein cannulation on behalf of the College of Anaesthesiologists of Ireland and observation of scores amongst novice and experienced operators.

BACKGROUND: Ultrasound-guided, internal jugular venous (IJV) cannulation is a core technical skill for anaesthesiologists and intensivists. OBJECTIVES: At a modified Delphi panel meeting, to define and reach consensus on a set of objective ultrasound-guided IJV cannulation performance metrics on behalf of the College of Anaesthesiologists of Ireland (CAI). To use these metrics to objectively score video recordings of novice and experienced anaesthesiologists. DESIGN: An observational study. SETTING: CAI, March to June 2016 and four CAI training hospitals, November 2016 to July 2019. PARTICIPANTS: Metric development group: two CAI national directors of postgraduate training (specialist anaesthesiolgists), a behavioural scientist, a specialist intensivist and a senior CAI trainee. Scoring by two blinded assessors of video recordings of novice ( n  = 11) and experienced anaesthesiologists ( n  = 15) ultrasound-guided IJV cannulations. MAIN OUTCOME MEASURES: A set of agreed CAI objective performance metrics, that is, steps, errors, and critical errors characterising ultrasound-guided IJV cannulation. The difference in performance scores between novice and experienced anaesthesiologists as determined by skill level defined as being below or above the median total error score (errors plus critical errors): that is, low error (LoErr) and high error (HiErr), respectively. RESULTS: The study identified 47 steps, 18 errors and 13 critical errors through six phases.Variability was observed in the range of total error scores for both novice (1 to 3) and experienced (0 to 4.5) anaesthesiologists. This resulted in two further statistically different subgroups (LoErr and HiErr) for both novice ( P  = 0.011) and experienced practitioners ( P  < 0.000). The LoErr-experienced group performed the best in relation to steps, errors and total errors. Critical errors were only observed in the experienced group. CONCLUSION: A set of valid, reliable objective performance metrics has been developed for ultrasound-guided IJV cannulation. Considerable skill variability underlines the need to develop a CAI simulation-training programme using these metrics.

Moving beyond the technical skills and promoting professionalism-the experience of the College of Anaesthesiologists of Ireland with incorporating the Medical Council Eight Domains of Good Professional Practice into Entrustable Professional Activities.

BACKGROUND: The goal of the College of Anaesthesiologists of Ireland (CAI) is to train qualified anaesthesiologists who embody all aspects of professionalism. The Medical Council of Ireland has identified Eight Domains of Good Professional Practice which guide the standards for postgraduate specialist training, including within the CAI. AIMS: Entrustable Professional Activities (EPAs) were adopted as the organising framework for a competency-based programme within CAI. The aims were (i) to ensure that the EPA-integrated competencies from across the full range of domains and (ii) to design workplace-based assessment which fosters a culture and practice of feedback above and beyond technical skills. METHODS: Four core EPAs were developed for trialling; competencies were tagged to the eight domains in an iterative development process. Feedback Reports were devised as tools for workplace-based assessment. Analysis of the Feedback Report data revealed how well the content reflected the full range of domains. RESULTS: 'Clinical Skills' is the domain to which most competencies within the EPAs were tagged. Analysis of the content of Feedback Reports also revealed an overrepresentation of that domain. This highlighted the apparent preference of consultants and trainees for selecting clinical aspects of an EPA to provide and receive feedback on, rather than professionalism or any of the other non-technical domains. CONCLUSIONS: We advocate and make recommendations for more effective incorporation of the non-technical domains of professional practice in the processes of curriculum development, teaching, learning, feedback and assessment.

Impact of heart failure and changes to volume status on liver stiffness: non-invasive assessment using transient elastography.

AIM: The impact of cardiac dysfunction on the liver is known as cardiac hepatopathy. In certain instances this can result in significant hepatic fibrosis or cirrhosis. The validity of non-invasive tools to assess hepatic fibrosis, such as FibroScan(®) which measures liver stiffness (LSM), has not been established in this setting. We examined the impact of cardiac dysfunction on LSM using FibroScan(®) and the influence of volume changes on LSM. METHODS AND RESULTS: A prospective, cross-sectional study examined the use of FibroScan(®) in subjects with left-sided heart failure (LHF, n = 32), right-sided heart failure (RHF, n = 9), and acute decompensated heart failure (ADHF, n = 8). The impact of volume changes upon LSM was further examined in the ADHF group (pre- and post-diuresis) and in a haemodialysis group (HD, n = 12), pre- and post-ultrafiltration on dialysis. Compared with healthy controls [n = 55, LSM = median 4.4 (25th percentile 3.6, 75th percentile 5.1) kPa], LSM was increased in all the cardiac dysfunction subgroups [LHF, 4.7 (4.0, 8.7) kPa, P = 0.04; RHF, 9.7 (5.0, 10.8) kPa, P < 0.001; ADHF, 11.2 (6.7, 14.3) kPa, P < 0.001]. Alteration in volume status via diuresis did not change the baseline LSM in ADHF [11.2 (6.7, 14.3) to 9.5 (7.3, 21.6) kPa, P > 0.05] with mean diuresis 5051 ± 1585 mL, or ultrafiltration in HD [6.0 (3.6, 5.1) vs. 5.7 (4.8, 7.0) kPa, P > 0.05] with mean diuresis 1962 ± 233 mL. CONCLUSION: Our findings support the concept of increased LSM in the cardiac failure population. LSM was not altered to a statistically significant level with acute volume changes.
