Competence of anesthesiology residents following a longitudinal point-of-care ultrasound curriculum.

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.

Project description:BackgroundThe use of point-of-care ultrasound as a diagnostic and interventional tool is rapidly becoming standard of care in critical care medicine; a standardized training curriculum is needed to ensure provider proficiency.ObjectiveThis study aimed to describe a longitudinal critical care ultrasound (CCUS) curriculum in a pulmonary critical care medicine (PCCM) fellowship training program. It evaluated the curriculum's impact on fellows' knowledge, skills, and self-reported confidence and retention of these attributes.MethodsWe conducted a prospective observational study of a longitudinal CCUS training program within a single PCCM fellowship training program. Knowledge, skills, and confidence of 22 fellows were assessed at baseline; after initial training; and at 6, 12, and 18 months in five domains (ultrasound basics, vascular, lung/pleural, abdomen, and cardiac). We quantified changes in CCUS knowledge, confidence, and skills by fellowship class and assessed for longitudinal retention of these three attributes. The difference in scores between new first-year fellows undergoing formal training and second-year fellows with previous informal training was compared at matched time points.ResultsAfter the initial formal training, there was a significant increase in knowledge, skills, and confidence scores, which were maintained or continued to increase up to 18 months. Fellows with 1 year of formal training also had a higher level of knowledge and skills than fellows with 1 year of informal training, although they had similar levels of self-reported confidence in their skills.ConclusionA formal, longitudinal CCUS curriculum implemented in a PCCM fellowship program improves trainees' knowledge and skills in various ultrasound domains in addition to their confidence in using ultrasound for patient care. A longitudinal curriculum results in retention of all three attributes and appeared to be more effective than an informal training program based on teaching during rounds, but this needs to be replicated in a larger cohort.
