Objective To evaluate the effectiveness
of Case-Based Learning (CBL) combined with Simulation-based Case Training (SCT)
in enhancing the quality of acute stroke teaching for neurology residents,
focusing on its overall impact on image interpretation skills, clinical decision-making
abilities, time efficiency, and theoretical knowledge.Methods A
retrospective cohort study design was adopted, including 135 residents who
received acute ischemic stroke training at the Department of Neurology, First
Affiliated Hospital of Zhengzhou University, from January 2022 to December
2024. Based on the introduction of the hybrid teaching model on January 15,
2023, participants were divided into two groups: the unexposed group (CBL, n=65), who received traditional CBL
teaching, and the exposed group (CBL+SCT, n=70),
who participated in CBL+SCT teaching, including simulated image interpretation,
thrombolysis/thrombectomy decision-making systems, and green channel process
simulations. All participants received the same acute ischemic stroke theoretical
course before the teaching intervention. Changes in image interpretation
accuracy, clinical decision-making accuracy, image interpretation time, process
formulation time, and theoretical exam scores were compared between the two
groups post-intervention. All teaching data were recorded by an automated
teaching management system.Results There were no significant
differences in demographic data and baseline ability indicators between the two
groups prior to the intervention (P>0.05).
Post-intervention, the exposed group outperformed the unexposed group in all
core skill dimensions. In image interpretation, the exposed group showed
significantly higher ASPECTS interpretation accuracy (82.9%), large vessel
occlusion recognition accuracy (84.3%), and "hemorrhage vs.
infarction" differentiation accuracy (88.6%) compared to the unexposed
group (P<0.001). In clinical
decision-making, the exposed group had significantly higher accuracy in
thrombolysis indications, thrombolysis contraindications, and thrombectomy
indications (all P<0.001). In
terms of time efficiency, the exposed group had significantly reduced image
interpretation time (82.07±4.63) s and process formulation time (48.91±5.34) s
compared to the unexposed group (P<0.001).
In theoretical exam scores, the exposed group scored significantly higher
(90.63±2.15) points compared to the unexposed group (87.62±3.16) points (P<0.001).Conclusion The
combination of CBL and SCT can significantly improve residents' ability in
imaging interpretation, clinical decision-making, and workflow management in
acute stroke, and is an efficient teaching model superior to traditional
methods.
