Brief Summary:
The process of medical information intake interpretation and diagnosis commonly referred to as clinical reasoning involves a complex interaction between visual perception and multiple cognitive processes Assessing students clinical reasoning skills is a challenging but critical task in developing an optimal teaching curriculum In this project the investigators plan to apply the eye-tracking technology to medical education with a specific goal of examining cognitive processing during reading medical chart and x-ray films Data collected by eye tracking technology will help investigate the perceptual and cognitive underpinnings of clinical reasoning CR misinterpretation and misdiagnosis among three participant groups with different levels of clinical experience Knowledge gained from this project will help to decode the intricate cognitive loop involved in medical interpretation Further this study will help to develop alternative methods of assessing students clinical reasoning skills and promote medical education with novel eye tracking technology
Detailed Description:
Objective
In this project the investigators plan to apply the eye-tracking technology to medical education with a specific goal of examining cognitive processing during clinical reasoning CR The investigators expect that by checking the eye movements of medical trainees during case and image reading a list of valid behavioral markers could be created to quantitatively classify the expertise identify the moment of decision-making difficulty and decode the source of the judgement errors To examine differences in CR processes across varying levels of expertise three categories of participants novice intermediate and expert will be recruited While participants eye motions are tracked participants will read a trauma case provide a diagnosis and propose a suitable treatment plan The investigators postulate that 1 different participant groups will produce significantly different CR outcomes measured by their score on diagnostic judgement and treatment plan 2 participants will display different gaze fixation patterns and 3 combining evidence from clinical judgement and eye behavior analysis will provide useful information regarding the source of judgment errors
Research MethodProcedures
Staff and students in the SSRL Surgical Simulation Research Lab with a difficulty level of health training background will be enrolled as participants in the study A trauma case with complex life-threatening situations will be presented The case is a trauma cases with multiple internal injuries The case will be summarized into a one-page description and 3 x-ray films Our participants will need to make a diagnosis and give a treatment plan based on case information displayed on a screen The total reading time will be 4 minutes During the case reading the Tobii X2-60 a high-resolution remote eye-tracker will be used to capture the participants eye movements In addition the investigators will develop a 15-20 quiz regarding the patients condition and the participants final diagnosis The total score and errors in the quiz will be used to describe participants overall quality of their clinical reasoning
The investigators will carefully examine participants eye motions and report their scanning patterns during case reading Specifically the investigators will look for moments when participants rapidly move their eyes saccade over a sentence before fixating on a particular word fixation These eye behavior parameters have previous associations with mental workload and reasoning processing methods which can be used to further analyze results
Plan for Data Analysis
The investigators will firstly compare quiz scores and eye behaviors variables across the three participant groups with different clinical experience levels The investigators will then analyze eye-scanning patterns on case readings across the three different groups Specifically The investigators predict that experts will achieve the highest score in quiz The investigators therefore will examine the experts short and long fixation locations over the case reading The assumption is that experts know where to find key information in the case description and mentally connect separate information together to generate an correct judgement in the short period of time Fixation spots recorded from the novice and intermediate groups will be compared with experts Differences will help us identify different visual searching strategies over different stages in the development of clinical reasoning skills Lastly the investigators will examine clinical judgement errors and check the root cause by connecting quiz errors with eye behaviors If a participant failed to give a long fixation to key case features in the case description the clinical decision error may be due to a checking problem If a participant performs a long fixation to key case features the clinical decision error may due to recognition or decision-making problems
