ABSTRACT
BACKGROUND:
Simulation for the management of massive hemoptysis is limited by the absence of a commercially available simulator to practice procedural skills necessary for management. RESEARCH QUESTION Is it feasible to create and validate a hemoptysis simulator with high functional task alignment? STUDY DESIGN ANDMETHODS:
Pulmonary and critical care medicine (PCCM) attending physicians from four academic institutions in the Denver, Colorado, area and internal medicine residents from the University of Colorado participated in this mixed-methods study. A hemoptysis simulator was constructed by connecting a 3-D-printed airway model to a manikin that may be intubated. Attending PCCM physicians evaluated the simulator through surveys and qualitative interviews. Attendings were surveyed to determine simulation content and appropriate assessment criteria for a hemoptysis simulation. Based on these criteria, expert and novice performance on the simulator was assessed.RESULTS:
The manikin-based hemoptysis simulator demonstrated adequate physical resemblance, high functional alignment, and strong affective fidelity. It was universally preferred over a virtual reality simulator by 10 PCCM attendings. Twenty-seven attendings provided input on assessment criteria and established that assessing management priorities (eg, airway protection) was preferred to a skills checklist for hemoptysis management. Three experts outperformed six novices in hemoptysis management on the manikin-based simulator in all management categories assessed, supporting construct validity of the simulation.INTERPRETATION:
Creation of a hemoptysis simulator with appropriate content, high functional task alignment, and strong affective fidelity was successful using 3-D-printed airway models and existing manikins. This approach can overcome barriers of cost and availability for simulation of high-acuity, low-occurrence procedures.Palabras clave
