Background: Laparoscopic camera navigation is vital to laparoscopic surgery, yet often falls to the most junior member of the surgical team who has limited laparoscopic operating experience. Previously published reports on simulation models fail to address qualitative scoring of movement, method of communication and correct physician location with respect to patient position. The purpose of this study was to develop and evaluate a novel laparoscopic camera navigation simulation model that addresses these deficiencies.Methods: A novel, low-cost laparoscopic camera navigational maze was constructed from pliable foam for use in a standard laparoscopic surgery box trainer. Participants (n = 37) completed a camera navigation exercise by following a pre-recorded set of verbal instructions using correct anatomic terminology that is used in the operating room, to simulate an actual operating room experience of receiving verbal cues from senior surgeons. The sample group consisted of participants at various levels of Obstetrics and Gynecology training, representing novice to expert laparoscopists. Each trial was recorded with a multi-channel video camera. Performances were scored by a blinded evaluator for excess gross and fine camera movements as well as overt errors, including camera collisions and failure to follow directions.Results: Our model demonstrated evidence of validity by discriminating performance by level of laparoscopic experience with a statistically significant decrease in number of movements and errors in experts compared to novices. A trend emerged toward improvement with each additional year of training, with reduced variability among performances in more experienced participants.Conclusions: This novel, low-cost box-trainer simulation model for laparoscopic camera navigation offers a mechanism for assessment of laparoscopic camera operation skills. Moreover, this model closely replicates operating room logistics and communication. Given the necessity for improved laparoscopic camera operation education, our model represents a unique, complementary tool to other laparoscopic simulation curricula. [ABSTRACT FROM AUTHOR]

Purpose: Skilled placement of peripherally inserted central catheters (PICC) has a profound impact on patient well-being and costs of care. The use of ultrasound-guided methods and prescribed training for cannulation skills are evidence-based practice recommendations. The purpose of this study was to compare two methods of PICC instruction on the acquisition of applied skills.Methods: Residents were randomly assigned to one of two groups (N = 16/16) of this blind-rater study and were trained to perform ultrasound-guided PICC cannulation using either simulation or apprenticeship methods. All residents were assessed placing a PICC in applied clinical patient care.Results: Residents who completed simulation training had significantly better transfer of skills to applied clinical practice than residents who received apprenticeship training, having better performance ratings on eight of nine procedure-specific task measures (p < 0.05) and higher success rates in endpoint PICC placement.Conclusions: These results support the use of prescribed simulation-based training for the acquisition of requisite skills associated with PICC placement and expand on similar studies that suggest the advantages of simulation-based training for central line placement. Additionally, the data suggest that training using a single simulation model may support the acquisition of both central venous catheterization and PICC skills. [ABSTRACT FROM AUTHOR]
