Using Electronic Virtual Patients for Evidence-Based Medicine and Clinical Reasoning

Explore how the use of electronic virtual patients can enhance skills in evidence-based medicine and clinical reasoning. This presentation discusses the traditional approach to problem solving and the problem-based learning (PBL) approach. Learn how knowledge and skills arise from working on patient cases and how to ask clinical questions. Access virtual patient cases on TUSK to practice clinical reasoning.

  9. Asking Clinical Questions • Background Questions(PBL1, Learning Questions) • general knowledge • many sources in HSL • [database, e-Books, e-Journals, • OvidMEDLINE,PubMed, TUSK, etc.] • Foreground Questions(PBL2, advanced LQ’s) • specific knowledge to make a clinical decision • 3 or 4 essential components • Patient and/or Problem • Intervention • Comparative intervention (…optional, if relevant) • Clinical Outcome

  10. P4 Cases *H. S. Barrows

  11. PBL core materials on TUSK….. …linked inside all group folders 4 - 5 students 1 facilitator per tutorial group Group - works through VP case (using ‘global’ navigation) ….individual work (LQs) outside group ..….....each group folder is unique ……….PICO submitted to librarian 45 – 50 PBL tutorial groups Background + ForegroundLQs

  12. *P4 Portable Patient Problem Pack • A simulated patient (cards TUSK) • An exercise in clinical reasoning • EVIDENCE: select History • EVIDENCE:select Exam • EVIDENCE:select Tests and Procedures • EVIDENCE: select Consultants • Manage the patient’s problem *H. S. Barrows

  17. ICR core materials on TUSK….. 20 students 1 master clinician per tutorial group Individual – works VP case (using ‘linear’ navigation) …….explore VP cases outside group ..….....answer questions during case ………. sub-groups submit group work NEW cases withMaster Clinician 10 ICR tutorial groups
