pattern-based learning: an educational model for radiology assistants

Background: studies show that planning, strategy making, andmodeling have greater impact on the achievement of learners thanother educational factors. the aim of the present study was toevaluate the changes in clinical competency of radiology residentsby teaching and training educational models of radiologic patternrecognition - diagnostic approach - feedback on diagnosis (paf).methods: this semi-experimental study was performed at mashhaduniversity of medical sciences from 2018 up to 2020. theparticipants were 60 radiology residents divided randomly into twogroups of 30 subjects in two educational centers. eight trainingsessions were held at one of the two educational centers forteaching this model to assistants. then, the clinical competency ofresidents was evaluated by four exams. in addition, residents'satisfaction was also determined by a confidential surveyconducted by the university. the parametric tests were used fordata analysis. p<0.0.5 was considered as the significance level.results: comparison of the scores of two groups in osce examshowed that in the second and third-year of being assistance, thescores of the intervention group were significantly better than thecontrol group (p=0.02 & 0.05), but no significant difference wasfound between the two groups in the formative (qualitative) andmultiple-choice question exams. about 82.7% of radiologyresidents were satisfied with this educational model.conclusion: pattern-based learning, including paf, is a practicalsuggestion for problem-based learning in medical imaging. it canlead to improvement of the clinical competency in radiologyresidents, especially levels 2 or 3.
