Eye-Tracking Technology to Determine Procedural Proficiency in Ultrasound-Guided Regional Anesthesia.

Background: Eye-tracking measures attention patterns, which may offer insight into evaluating procedural expertise. The purpose of this study was to determine the feasibility of using eye tracking to assess visual fixation patterns when performing an ultrasound-guided regional anesthesia procedure and to assess for differences between experienced, intermediate, and novice practitioners. Methods: Participants performed an ultrasound-guided sciatic nerve block 3 times on a fresh cadaver model while wearing eye-tracking glasses. Gaze fixation and dwell time on each location were compared between participants. Eye-gaze paths were used to derive a measure of entropy, or how often participants switched gaze fixations between locations. Results: Five attending anesthesiologists, 5 third-year anesthesiology residents with prior ultrasound-guided regional anesthesia experience, and 5 medical students completed the study. Individuals with more experience were more likely to successfully perform the sciatic nerve block (5/5 attendings, 5/5 residents, 0/5 students; P = .002) and performed the procedure faster (average: attendings 62.6 seconds, residents 106.4 seconds, students 134.4 seconds; P = .089). Participants were progressively faster with practice (Trial 1: 41.8 seconds, Trial 2: 29.2 seconds, Trial 3: 28.9 seconds; P = .012), and the average number of eye shifts per trial decreased from 10.8 to 6.5 to 6 (P = .010). Attending physicians spent significantly less time fixating on the ultrasound monitor compared to trainees (P = .035). Average visual entropy progressively decreased from Trial 1 to Trial 3 (P = .03) and with greater experience (P = .15). There was a strong correlation between entropy and time on task (r(16) = 0.826, P = .001). Conclusions: Experienced providers make fewer back-and-forth visual fixations, spend less time in the procedure, and demonstrate less entropy during ultrasound-guided regional anesthesia procedures. Mobile eye-tracking has the potential to provide additional objective measures of performance that may help not only determine procedural competence but also distinguish between levels of proficiency.

An Antiracism Approach to Conducting, Reporting, and Evaluating Pediatric Critical Care Research.

Reporting race and ethnicity without consideration for the complexity of these variables is unfortunately common in research. This practice exacerbates the systemic racism present in healthcare and research, of which pediatric critical care is not immune. Scientifically, this approach lacks rigor, as people are grouped into socially derived categories that are often not scientifically justified, and the field is denied the opportunity to examine closely the true associations between race/ethnicity and clinical outcomes. In this Special Article for Pediatric Critical Care Medicine, we introduce an antiracism approach to conducting, reporting, and evaluating pediatric critical care research. We propose four recommendations: 1) race and ethnicity are social constructs that should be evaluated as such, with researchers considering the context and relevance of related social determinants of health; 2) race and ethnicity data should be collected with sufficient detail to allow detection of meaningful results and minimize the risk of overgeneralizing findings; 3) as health equity research evolves, the pediatric critical care research field must adapt and proactively strive for inclusivity; and 4) the research community, including investigators, authors, research ethics committees, funding organizations, professional organizations, and journal editorial boards, are all accountable for rigorously conducting and reporting race/ethnicity in research. Taking an antiracism approach to research requires the field to ask the difficult question of why racial/ethnic differences exist to eliminate healthcare disparities and optimize healthcare outcomes for all children.

Transport Medical Control Education for Pediatric Critical Care Fellows: A National Needs Assessment Study.

OBJECTIVES: Characterize transport medical control education in Pediatric Critical Care Medicine fellowship. DESIGN: Cross-sectional survey study. SETTING: Pediatric Critical Care Medicine fellowship programs in the United States. SUBJECTS: Pediatric Critical Care Medicine fellowship program directors. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We achieved a 74% (53/72) response rate. A majority of programs (85%) require fellows to serve as transport medical control, usually while carrying out other clinical responsibilities and sometimes without supervision. Fellows at most programs (80%) also accompany the transport team on patient retrievals. Most respondents (72%) reported formalized transport medical control teaching, primarily in a didactic format (76%). Few programs (25%) use a standardized assessment tool. Transport medical control was identified as requiring all six Accreditation Council for Graduate Medical Education competencies, with emphasis on professionalism and interpersonal and communication skills. CONCLUSIONS: Transport medical control responsibilities are common for Pediatric Critical Care Medicine fellows, but training is inconsistent, assessment is not standardized, and supervision may be lacking. Fellow performance in transport medical control may help inform assessment in multiple domains of competencies. Further study is needed to identify effective methods for transport medical control education.

Assessing Competence in Central Venous Catheter Placement by Pediatric Critical Care Fellows: A National Survey Study.

OBJECTIVES: To describe the current approach to initial training, ongoing skill maintenance, and assessment of competence in central venous catheter placement by pediatric critical care medicine fellows, a subset of trainees in whom this skill is required. DESIGN: Cross-sectional internet-based survey with deliberate sampling. SETTING: United States pediatric critical care medicine fellowship programs. SUBJECTS: Pediatric critical care medicine program directors of Accreditation Council for Graduate Medical Education-accredited fellowship programs. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A working group of the Education in Pediatric Intensive Care Investigators research collaborative conducted a national study to assess the degree of standardization of training and competence assessment of central venous catheter placement across pediatric critical care medicine fellowship programs. After piloting, the survey was sent to all program directors (n = 67) of Accreditation Council for Graduate Medical Education-accredited pediatric critical care medicine programs between July 2017 and September 2017. The response rate was 85% (57/67). Although 98% of programs provide formalized central venous catheter placement training for first-year fellows, only 42% of programs provide ongoing maintenance training as part of fellowship. Over half (55%) of programs use a global assessment tool and 33% use a checklist-based tool when evaluating fellow central venous catheter placement competence under direct supervision. Only two programs (4%) currently use an assessment tool previously published and validated by the Education in Pediatric Intensive Care group. A majority (82%) of responding program directors believe that a standardized approach to assessment of central venous catheter competency across programs is important. CONCLUSIONS: Despite national mandates for skill competence by many accrediting bodies, no standardized system currently exists across programs for assessing central venous catheter placement. Most pediatric critical care medicine programs use a global assessment and decisions around the ability of a fellow to place a central venous catheter under indirect supervision are largely based upon subjective assessment of performance. Further investigation is needed to determine if this finding is consistent in other specialties/subspecialties, if utilization of standardized assessment methods can improve program directors' abilities to ensure trainee competence in central venous catheter insertion in the setting of variable training approaches, and if these findings are consistent with other procedures across critical care medicine training programs, adult and pediatric.
