Development and validation of a training and assessment tool for laparoscopic radical nephrectomy.

INTRODUCTION: Laparoscopic radical nephrectomy(LRN) is a cornerstone in managing renal cancer and small renal masses. Twenty-first century surgical training faces challenges, thus must be efficient and safe so surgeons attain relevant skills, protecting patients and operative outcomes. This study aimed to systematically develop a tool for training and assessment in LRN and validate the developed tool for use by trainee urologists. METHODS: This prospective, longitudinal, multi-institutional study was undertaken from September 2014 - June 2015. Healthcare Failure Mode and Effect Analysis was utilised for development and followed by validation where the assessment tool was distributed to five specialists to increase content validity. Four experts were observed as a multi-institutional approach. Hand-assisted, transperitoneal and retroperitoneal approaches were considered. RESULTS: The LRN Assessment Tool comprised four phases, 17 processes, 41 sub-processes. Four surgeons and operating teams were observed across four hospitals for 19.5hours (5.75h hand-assisted, 8.75h trans-peritoneal, 5h retro-peritoneal). After hazard analysis, three checklists were constructed. Those for hand-assisted LRN and transperitoneal LRN contained four phases, 20 processes, 33 sub-processes and that for retroperitoneal LRN contained four phases, 20 processes, 30 sub-processes. These were merged to form one assessment tool. The final result was a four phase LRN Assessment Tool with 17 processes, 41 sub-processes. All participants agreed the final LRN Assessment Tool included pertinent steps. CONCLUSIONS: The LRN Assessment Tool was developed using Healthcare Failure Mode and Effect Analysis risk analysis to ensure hazardous procedural sub-steps were included. Validation ascertained important processes were not overlooked. Full application through a pilot study must be undertaken.
