Construct validity of a novel, objective evaluation tool for the basics of open laparotomy training using a simulated model

Abstract Background We describe initial success in designing and implementing an objective evaluation for opening and closing a simulated abdomen. Methods (1) An assessment for laparotomy was created using peer-reviewed literature, texts, and the input of academic surgeons nationally; (2) the assessment was evaluated for construct validity, comparing the videotaped performance of laparotomy by surgical experts and novices on a viscoelastic model; and (3) the basics of open laparotomy training (BOLT) curriculum was piloted with junior residents to evaluate efficacy at improving performance. Results Experts performed better than novices opening (.94 vs .51; P P P P P  = .01). After completing the BOLT curriculum, novices improved for opening (1.00 vs .50; P  = .014), closing (.80 vs .10; P  = .014), and overall score (.87 vs .23; P  = .014). Conclusions We demonstrate construct validity of an evaluation tool for simulated laparotomy, and pilot efforts with the BOLT curriculum have shown promise.
