Background: This study assessed the reliability of surgical resident self-assessment in comparison with faculty and standardized patient (SP) assessments during a structured educational module focused on perioperative management of a simulated adverse event., Methods: Seven general surgery residents participated in this module. Residents were assessed during videotaped preoperative and postoperative SP encounters and when dissecting a tumor off of a standardized inanimate vena cava model in a simulated operating room., Results: Preoperative and postoperative assessments by SPs correlated significantly (P < .05) with faculty assessments (r = .75 and r = .79, respectively), but not resident self-assessments. Coefficient alpha was greater than .70 for all assessments except resident preoperative self-assessments., Conclusions: Faculty and SP assessments can provide reliable data useful for formative feedback. Although resident self-assessment may be useful for the formative assessment of technical skills, results suggest that in the absence of training, residents are not reliable self-assessors of preoperative and postoperative interactions with SPs.

Background: This pilot project involved the development of a structured, experiential, educational module using a bench model technical skills simulation and standardized patients. It integrated teaching and assessment of clinical, technical, and interpersonal skills, as well as professionalism within the context of an adverse surgical event., Methods: General surgery residents (postgraduate year [PGY] 2, 3) were asked to participate in the pre-, intra-, and postoperative management of a patient with a retroperitoneal sarcoma. Residents' performances during the module were assessed by standardized patients and faculty, and residents were provided feedback during debriefing sessions., Results: Resident performance during the module was appropriate for the level of training. Residents found this module to be a realistic, challenging, and beneficial learning experience., Conclusions: Novel educational modules such as this one may serve as a useful addition to resident education in surgery residency programs, particularly in addressing patient safety and the core competencies. Reliability of the model may be enhanced by modifications of the module.

Background: Through site-directed mutagenesis we have created a favorable fibroblast growth factor-1 (FGF-1) mutant (S130K) and linked it to a heparin-binding growth-associated molecule (HBGAM) to form the chimera S130K-HBGAM creating a heparin-independent, endothelial cell (EC)-specific mitogen., Methods: The proliferative responses of primary canine carotid artery smooth muscle cells (SMC) and jugular vein EC to FGF-1, S130K, or S130K-HBGAM, with and without heparin (5 U/mL), was quantitated by measuring tritiated thymidine uptake over 24 hours and expressing the results as percent of positive control (20% fetal bovine serum [FBS]) for group comparison., Results: Unlike FGF-1, both S130K and S130K-HBGAM are heparin-independent mitogens for EC and SMC. S130K-HBGAM was equivalent to FGF-1 with heparin at 6 nmol/L. S130K-HBGAM did not demonstrate relative EC specificity in this assay., Conclusions: At higher concentrations, S130K-HBGAM is a potent, heparin-independent EC and SMC mitogen. Co-culture assays and in vivo delivery models may demonstrate EC specificity not identified in this single cell type proliferation assay.
