Table 1 Procedural proficiency checklist

From: Sequential learning of psychomotor and visuospatial skills for laparoscopic suturing and knot tying – study protocol for a randomized controlled trial “The shoebox study”

Procedure assessment Yes/No
Needle position 1 1 Held at one half to two thirds distance from the tip  
  2 Angle 90° ± 20°  
  3 Uses tissue or other instrument for stability  
  4 Attempts at positioning (≤3)  
Needle driving 1 (entry to incision) 5 Entry at 60° to 90° to the tissue plane  
6 Driving with one movement  
  7 Single point of entry through the tissue  
  8 Removes the needle along its curve  
Needle position 2 9 Held at one half to two thirds distance from the tip  
  10 Angle 90° ± 20°  
  11 Uses tissue or other instrument for stability
