Subclaims¶

q2 i? Most comparisons of virtual patient design variants (linear vs branched, scaffolded vs not, worked vs unworked, spaced vs nonspaced, solving vs constructing) showed no significant differences in knowledge or skills outcomes. → Kononowicz AA 2019 q2 i? Exceptions: empathic human feedback improved communication skills (P<.03), narrative design beat problem-solving for communication skills (P=.03), and representational scaffolding improved diagnostic efficiency (P=.045). → Kononowicz AA 2019 (2)

q2 · i? · quant-synthesis · r3

Narrative synthesis of design-variant RCTs in the knowledge domain; only one study (pedagogic vs problem-solving vs high-fidelity design, P<.01) reached significance. The review states trials comparing design variants "were not numerous enough to give clear recommendations".

"Comparing linear and branched virtual patients [92], scaffolded versus nonscaffolded [93], worked and unworked examples [97], virtual patient with usability extensions [94], self-determined versus mandatory integration [98], spaced versus nonspaced release of cases [99], and virtual patient solving versus virtual patient design exercises [100] resulted in no significant differences in knowledge outcomes."

q2 · i? · quant-synthesis · r3

Skills-domain design comparisons: human empathic feedback and narrative structure each outperformed their contrast on communication skills; Braun et al found scaffolding improved diagnostic efficiency (P=.045); constructing versus solving showed no difference (P=.54).

"Foster et al [95] showed that virtual patients with emphatic feedback were significantly better in training communication skills than those virtual patients without feedback (P<.03). In the study by Bearman et al [91], narrative virtual patients were significantly better than problem-solving virtual patients in conveying communication skills (P=.03)."

Discussion¶

Related Claims¶

• Student satisfaction with virtual patients is generally positive, with item-level comparisons dominating and some confidence exceptions — related
• In the few trials comparing them, virtual patients showed no significant knowledge differences versus other digital education, and skills differences in only one of three studies — related
• Controlled GenAI virtual-patient and communication studies reported short-term skill gains, but positive findings were not universal — related
• Related-case overlap between MedGame Bench train and test splits shows no significant performance difference — a narrower finding that bears on this claim
