ABSTRACT

PURPOSE: Point-of-care ultrasound (POCUS) facilitates diagnostic, procedural, and resuscitative applications in anesthesiology. Structured POCUS curricula improve learner satisfaction, test scores, and clinical management, but the learning curve towards competency and retention of skills over time remain unknown. METHODS: We conducted a prospective observational study to determine when anesthesiology trainees enrolled in a POCUS curriculum achieve competency in POCUS skills. We also investigated the learning curve of trainees' competency using a POCUS-specific competency-based medical education assessment. The structured, longitudinal POCUS curriculum included online lectures, journal articles, live model scanning sessions, video review of cases, and a portfolio of supervised scans. Point-of-care ultrasound scanning sessions on standardized patients were conducted in the simulation lab for 2.5 hr a week and each resident completed eight sessions (20 hr) per academic year. At each scanning session, timed image acquisition scores were collected and POCUS skills entrustment scale evaluations were conducted. The primary outcome was the number of supervised scans and sessions required to achieve a mean entrustment score of 4 ("may use independently"). Secondary outcomes included image acquisition scores and retention of skills after six months. RESULTS: The mean (standard deviation) number of supervised scans required for trainees (n = 29) to reach a mean entrustment score of ≥ 4 was 36 (10) scans over nine sessions for rescue echo. A mean entrustment score of ≥ 4 was observed for lung ultrasound after a mean (SD) of 8 (3) scans over two sessions. CONCLUSIONS: Our study shows that anesthesiology residents can achieve competence in rescue echo and lung ultrasound through participation in a structured, longitudinal POCUS curriculum, and outlines the learning curve for progression towards competency.


RéSUMé: OBJECTIF: L'échographie ciblée (POCUS) facilite les applications diagnostiques, procédurales et de réanimation en anesthésiologie. Les programmes de cours structurés en échographie ciblée améliorent la satisfaction des apprenants ainsi que leurs résultats aux examens et leur prise en charge clinique, mais nous connaissons mal la courbe d'apprentissage vers la compétence et le maintien des compétences au fil du temps. MéTHODE: Nous avons réalisé une étude observationnelle prospective afin de déterminer quand les stagiaires en anesthésiologie inscrits à un programme d'échographie ciblée atteignaient les compétences dans ce domaine. Nous avons également étudié la courbe d'apprentissage des compétences des résidents à l'aide d'une évaluation de la formation médicale fondée sur les compétences spécifique à l'échographie ciblée. Le programme d'échographie ciblée structuré et longitudinal comprenait des cours en ligne, des articles de revues, des séances d'examens d'échographie modèles en direct, une revue vidéo de cas et un portefeuille d'examens échographiques supervisés. Des séances d'échographie ciblée sur des patients standardisés ont été réalisées dans le laboratoire de simulation pendant 2,5 heures par semaine et chaque résident a suivi huit séances (20 heures) par année scolaire. À chaque session d'examen échographique, des scores chronométrés d'acquisition d'images ont été colligés et des évaluations d'échelle de confiance des compétences d'échographie ciblée ont été réalisées. Le critère d'évaluation principal était le nombre d'examens et de séances d'échographie supervisés requis pour obtenir un score moyen de confiance de 4 (« peut réaliser une échographie indépendamment ¼). Les critères d'évaluation secondaires comprenaient les scores d'acquisition d'images et le maintien des compétences après six mois. RéSULTATS: Le nombre moyen (écart type) d'examens supervisés requis pour les résidents (n = 29) pour atteindre un score de confiance moyen ≥ 4 était de 36 (10) examens sur neuf sessions pour l'échographie de sauvetage. Un score de confiance moyen ≥ 4 a été observé pour l'échographie pulmonaire après une moyenne (ET) de 8 (3) examens sur deux séances. CONCLUSION: Notre étude montre que les résidents en anesthésiologie peuvent acquérir des compétences en échographie de sauvetage et en échographie pulmonaire en participant à un cours d'échographie ciblée structuré et longitudinal, et décrit la courbe d'apprentissage pour la progression vers la compétence.

ABSTRACT

INTRODUCTION: Compared with other specialties, anesthesiologists are at increased risk of acquiring a blood-borne pathogen (BBP) through needle-stick injuries (NSIs). Safety-engineered intravenous catheters (SEICs) have been designed to reduce NSIs but have not been well received. Our objective was to determine SEIC usage by pediatric anesthesiologists, including availability, utilization, perceived utility, and sources of NSI before and after legislation mandating their use in Canada. METHODS: After Ethics Committee approval, we conducted two electronic surveys of Canadian pediatric anesthesiologists (CPAs) based in tertiary care settings. Survey responses from May through August 2012 and June through September 2006 were considered. In addition to SEIC use and perceived utility, respondents described factors influencing SEIC adoption and workplace NSIs. Standard metrics of survey validity and reliability were employed. RESULTS: Completed questionnaires were returned by 154 (69%) and 124 (53%) respondents in 2012 and 2006, respectively, representing 15 of 16 Canadian pediatric tertiary care centres. Reported SEIC availability increased in hospitals (82% vs 98%; difference in proportion 16%, 95% confidence interval [CI]: 9 to 24%; P < 0.001) and in operating rooms (62% vs 86%; difference in proportion 24%, 95% CI: 13 to 34%; P < 0.001) Respondents' report of "routine" personal use of SEICs increased from 43 of 76 (56%) to 112 of 132 (85%) (difference in proportion 29%, 95% CI: 16 to 41%; P < 0.001). Attitudes concerning perceived utility of SEICs remained unchanged and evenly split between respondents. "Awkward handling" remained the primary reason for non-use. In all, 71 (48%) and 60 (48%) respondents reported recent contaminated NSIs in 2012 and 2006, respectively. The majority were related to a needle on a disposable syringe. DISCUSSION: Despite only moderate perceived utility, SEIC uptake among CPAs is high. However, NSIs remain common. Several opportunities to reduce the risk for work-related BBP transmission among CPAs were evident.
