Simulation Versus Problem Based Learning for Cerebrospinal Drainage Catheter Insertion and Management: A Randomized Trial in a Large Academic Anesthesiology Residency Program.

OBJECTIVE

Cerebrospinal fluid drainage catheter-related complications can be reduced by following strict guidelines during their introduction, maintenance, and removal. The authors therefore aimed to determine whether simulation-based learning would improve senior anesthesiology residents' patient care performance during the insertion and management of these catheters compared to interactive problem-based learning (PBL) using the Anaesthetists' Non-Technical Skills global rating scale (ANTS).

DESIGN

Prospective randomized trial.

SETTING

Vascular or hybrid operating rooms in a large academic tertiary care center.

PARTICIPANTS

Senior anesthesia (categorical anesthesia-3) residents rotating through the vascular rotation at the Cleveland Clinic main campus in the period between December 2014 and June 2017.

INTERVENTION: Simulation-based learning versus PBL.

MEASUREMENTS AND MAIN

RESULTS

The primary outcome was the composite score (ANTS global rating scale) achieved by participating residents as evaluated by their supervising anesthesiologists. Out of 28 residents who completed the study, N = 13 were randomized to simulation-based learning and N = 15 residents to the PBL approach. The median (first quartile, third quartile) composite score was 16 (14, 16) and 16 (13, 16) for the simulation-based learning and PBL groups, respectively. There was no significant difference in staff evaluation of the 2 study groups (p = 0.48) with an estimated odds (95% confidence interval) of getting a better staff evaluation score of 1.9 (0.3-10.6) times higher comparing simulation versus traditional training groups.

CONCLUSION

Compared to interactive PBL, simulation-based learning does not result in a statistically significant improvement in anesthesia resident performance during insertion and management of cerebrospinal fluid drainage catheters.
