Safer Surgery part 8. There have been few research investigations into how highly trained doctors and nurses work together to achieve safe and efficient anaesthesia and surgery. While there have been major advances in surgical and anaesthetic procedures, there are still significant risks for patients during operations and adverse events are not unknown. Due to rising concern about patient safety, surgeons and anaesthetists have looked for ways of minimising adverse events. | 44 Safer Surgery system itself is located on a secure site at . As well as giving considerable benefits by automating tedious aspects of recording PBA the online version offers the opportunity to gather information in real time and capture it so that trainees will submit a realistic record of their progression rather than simply retaining those PBAs they deem their best - which is counter to the core values of the system. Naturally electronic data permit one to contrast and compare data from different training programmes and differing contexts of training so that hopefully an evaluation may be made of learning in surgical training. International Compatibility Considerable interest from overseas in the orthopaedic curriculum and in particular with the PBA tools has led to a number of proposed international pilot projects. International compatibility of surgical training systems is a key issue in relation to making it possible for trainees to complete part of their training overseas but at a wider level may have considerable consequences for the mobility of surgical labour. The PBA tool may offer a way of ensuring that widely differing training systems are producing compatible surgical skill sets. NOTSS It is hoped that we will in the near future have the opportunity to combine the progress made in both the Non-Technical Skills for Surgeons NOTSS project see Chapter 2 in this volume and in PBAs by either producing a new assessment tool based on the PBA or to integrate behavioural markers from NOTSS into the existing PBA. PowerPoint Guidance For PBA as for all elements of the orthopaedic curriculum we have produced PowerPoint guides available through the website. The use of this technology in preference to a user manual enables a trainer and trainee to sit together and review the guidance and also for a programme director to present the guide in a group setting. These guides have been developed for all PBA applications to date and will be added to as
