Thesis (M.S.)--Boston University

Spurred by recent press reports and other concerns this thesis focuses on the quality of surgical instruments. The current situation is reviewed by considering the regulatory framework and by investigating the quality of newly purchased instruments. A range of test protocols based on British Standards and best practices from industry were developed. These were designed to be practical in the real world situation and a user-friendly database was built to collate all the relevant data and inform the Supply Chain. The conditions experienced by instruments during their lifetime in the health care environment, especially in cleaning and disinfection were studied and as many instruments implicated in Incidents as possible investigated to understand the possible root causes of failure. During this work the importance and debate over surface finish, passivation and disinfection processes became apparent and research was carried out into the effect on wettability and drying mechanism of passivation and repeated disinfection cycles on various typical surface finishes. This concentrated on the environment within the health service unlike other studies which have been concerned with more aggressive industrial situations. Standards and Procedures on the care of instruments have been established in order to improve the current management of surgical instruments and to ensure that they are and remain fit for purpose.

Background: Considerable resources have been invested in low and high fidelity simulators in surgical training. The purpose of this study was to establish construct and predictive validity for the Fundamentals of Laparoscopic Surgery (FLS, low fidelity box trainer) and LapVR (high fidelity virtually reality) training systems and to establish construct validity for two operative ratings scales (GOALS and OSATS) in our center. Methods: 26 participants performed tasks from the FLS program and the LapVR simulator as well as a human laparoscopic cholecystectomy. Performance was evaluated using FLS and LapVR metrics, and the previously validated global rating scales. Results: GOALS and OSATS demonstrated construct validity. Construct and predictive validity was also strongly demonstrated for FLS tasks but only indeterminately for LapVR. Conclusions: The high cost LapVR remains experimental in resource constrained training programs. Efforts should be focused on utilizing the well-validated, lower cost FLS video trainer for assessment of laparoscopic skills.
