Conditions
Brief summary
Currently transplant during organ procurement specially trained theatre technicians take photos of the potential donor liver prior to aortic cross clamp and following reperfusion. These pictures are then sent to the transplant surgeon, transplant coordinator, liver pathologist via secure communication and stored on the liver database. In addition a biopsy is sent to the lab to confirm viability. On the basis of these pictures the surgeon either decides to go ahead with surgery or wait for the biopsy. An operating theatre is placed on hold from the time the team leave for organ retrieval until the biopsy results come back at which point they either proceed with the transplant or cancel it. This process can take several hours during which time each person who has seen the photo claims to be as accurate as the eventual laboratory result in predicting organ viability, organ age and organ fat content. We would like to create user response curves to see if there is a correlation between health care provider groups and their ability to predict organ viability in liver transplant

No of Participants: 25: 5 Liver transplant surgeons > 1 year experience; 5 Theatre technicians > 1 year experience; 5 Transplant coordinators > 1 year experience; 5 Consultant anaesthetists > 1 year experience; 5 Liver Pathologists >1 year experience. Time Scale: 1 year Method: The pictures of 25 organ procurements will be taken from existing records and de-identified (50 pictures total). Each participant will be sent an invitation to their Austin Health email to participate in this project with a link to a REDCaps survey. Consent will be implied by filling out the survey. Anyone not wishing to take part will not be required to do so. The survey will contain the following demographic questions: Occupation, Number of years in current role. There will then be an image showing pre and post perfusion pictures of a donor liver and participants will be asked to assess them for organ viability, organ age (to nearest 10 years), percentage fat (nearest 5%) and fibrosis score. In order to maintain interest, there will also be two sham photos (chopped liver, foie grass). The survey will take approximately 10 minutes to complete and can only be filled out by each participant once. We will ask participants to fill out the survey using their smartphones as this will mimic the conditions they are likely to see pre procurement liver photos in the clinical setting The survey results will be exported into an Excel spread sheet prior to data analysis. Answers for each group would be compared with actual donor age, organ viability and the laboratory result for percentage fat. Data Analysis: The results for each group will be combined and receiver operating curves constructed.
