Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i3 AR telestration reduced mean errors per task roughly tenfold versus verbal instruction (0.18 vs 1.94, P<.01, ηp²=0.92). → El Ashry M 2026 q3 i? AR-based ECMO cannulation instructions reduced knowledge-related errors by 66% in the more complex second procedure (18 vs 53 errors, P<.05), with handling errors unchanged. → El Ashry M 2026 (2) q3 i? AR telestration groups achieved critical view of safety in 79.5% of procedures versus 41.4% with verbal guidance (P≤.001), and reduced complication rates (13.3% vs 40%, P=.02). → El Ashry M 2026 (3)

Evidence¶

El Ashry M 2026¶

El Ashry M, El Ashry A, Khalique H, Abdalle Y, Yeung T. (2026). Augmented Reality in Surgical Training: Systematic Review of Its Impact on Technical Performance in Surgical Trainees. JMIR Medical Education. https://doi.org/10.2196/71572

q3 · i3 · review · r2

Crossover RCT (n=40 MIS-naive medical students) of iSurgeon AR telestration versus verbal guidance on laparoscopic tasks; the review reports "a mean of 0.18 errors per task compared with 1.94" with P<.01 and ηp²=0.92.

"Felinska et al [4] demonstrated the most dramatic reduction, with AR-instructed trainees making a mean of 0.18 errors per task compared with 1.94 for the verbal instruction group (P<.01; ηp²=0.92), representing a tenfold reduction in error rate."

El Ashry M 2026 (2)¶

q3 · i? · review · r3

Crossover RCT (n=21 medical students) comparing HoloLens 2 step-by-step AR guidance with conventional paper/video SOP for ECMO cannulation; the review reports the 66% knowledge-error reduction with handling errors unchanged.

"Wolf et al [1] found that AR-based extracorporeal membrane oxygenation cannulation instructions resulted in a 66% reduction in knowledge-related errors for the more complex second procedure (18 vs 53 errors; P<.05), while handling errors were unchanged"

El Ashry M 2026 (3)¶

q3 · i? · review · r2

Parallel RCT (n=40 medical students) across 10 ex vivo laparoscopic cholecystectomies comparing iSurgeon AR telestration with verbal guidance; the review reports the CVS contrast of 79.5% versus 41.4% (P≤.001).

"Cizmic et al [3] reported that the iSurgeon group incurred significantly fewer total complications and achieved the critical view of safety in 79.5% of procedures compared with only 41.4% in the verbal guidance group (P≤.001)."

Discussion¶

AR's effect on procedure and training time is mixed: large gains in discrete structured tasks but no difference for complex procedures — related
AR guidance improves objective technical accuracy in surgical trainees, most strongly in tasks with high visuospatial demands — a narrower finding that bears on this claim
AR telestration lowers cognitive workload during surgical training as measured by validated instruments — related
For lower-stakes basic skills, AR shows noninferiority rather than superiority over traditional instruction — reports the opposite
