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.

Um die Langzeitfolgen eines Delirs bei kritisch Kranken zu mildern, wird vielerorts auf eine Akuttherapie mit Antipsychotika gesetzt. Eine US-amerikanische Forschungsgruppe äußert jetzt erhebliche Vorbehalte gegen dieses Vorgehen. Denn es gibt neue Daten zum Langzeiteffekt von Haloperidol bzw. Ziprasidon versus Placebo.
