Objectives
Understanding of the workflow of perioperative ultrasound (US) examination is an integral
component of proficiency. Workflow consists of the practical steps prior to executing
an US examination (eg, equipment operation). Whereas other proficiency components
(ie, cognitive knowledge and manual dexterity) can be tested, workflow understanding
is difficult to define and assess due to its contextual and institution-specific nature.
The objective was to define the workflow components of specific perioperative US applications
using an iterative process to reach a consensus opinion.
Design
Expert consensus, survey study.
Setting
Tertiary university hospital.
Participants
This study sought expert consensus among a focus group of 9 members of an anesthesia
department with experience in perioperative US. Afterward, 257 anesthesia faculty
members from 133 academic centers across the United States were surveyed.
Interventions
A preliminary list of tasks was designed to establish the expectations of workflow
understanding by an anesthesiology resident prior to clinical exposure to perioperative
US. This list was modified by a focus group through an iterative process. Afterwards,
a survey was sent to faculty members nationwide, and Likert scale ratings for each
task were obtained and reviewed during a second round.
Measurements and Main Results
Consensus among members of the focus group was reached after 2 iterations. 72 participants
responded to the nationwide survey (28%), and consensus was reached after the second
round (Cronbach’s α = 0.99, ICC = 0.99) on a final list of 46 workflow-related tasks.
Conclusions
Specific components of perioperative US workflow were identified. Evaluation of workflow
understanding may be combined with cognitive knowledge and manual dexterity testing
for assessing proficiency in perioperative US.
