Attaining expertise in regional anaesthesia training using a multifactorial approach incorporating deliberate practice.
The most effective way of delivering regional anaesthesia training and the best means of demonstrating competency have not been established. Clinical competency, based on the Dreyfus and Dreyfus lexicon, appears unachievable using current training approaches. Lessons should be taken from the worlds of music, chess, and sports. Modern skills training programmes should be built on an explicit and detailed understanding with measurement of a variety of factors such as perception, attention, psychomotor and visuospatial function, and kinesthetics, coupled with quantitative, accurate, and reliable measurement of performance.

Virtual reality-based analgesia: towards a novel framework for the biopsychosocial management of chronic pain.
Virtual reality (VR) holds unmeasured potential as a multicomponent tool for managing chronic pain by adapting conventional in-person biopsychosocial pain management strategies into one virtual space. We review recent evidence showcasing the successful integration of cognitive behavioural therapy, mindfulness-based stress reduction, embodiment techniques, and physical therapy into VR environments, demonstrating positive outcomes in patients with chronic pain. We propose that future clinical and basic research build on this by integrating pain neuroscience techniques to help better understand pathophysiological pain mechanisms and treatment response. This could help facilitate early assessment and personalised treatment of chronic pain using a VR-based biopsychosocial approach.

Predictive modelling for postoperative acute kidney injury: big data enhancing quality or the Emperor's new clothes?
The increased availability of large clinical datasets together with increasingly sophisticated computing power has facilitated development of numerous risk prediction models for various adverse perioperative outcomes, including acute kidney injury (AKI). The rationale for developing such models is straightforward. ⋯ Some of the purported benefits of predictive modelling, particularly when applied to postoperative AKI, might not fare well under detailed scrutiny. Future research should address existing limitations and seek to demonstrate both benefit to patients and value to healthcare systems from implementation of these models in clinical practice.

Hyperfibrinolysis: potential guidance for decision-making to avoid futile extracorporeal cardiopulmonary resuscitation.
Out-of-hospital cardiac arrest (OHCA) is associated with very poor outcomes. Extracorporeal cardiopulmonary resuscitation (eCPR) for selected patients is a potential therapeutic option for refractory cardiac arrest. However, randomised controlled studies applying eCPR after refractory OHCA have demonstrated conflicting results regarding survival and good functional neurological outcomes. eCPR is an invasive, labour-intensive, and expensive therapeutic approach with associated side-effects. ⋯ Studies in trauma patients demonstrate a high mortality rate in those with established hyperfibrinolysis upon emergency room admission. Similar findings have now been reported for the first time in OHCA patients. Hyperfibrinolysis upon admission diagnosed by rotational thromboelastometry was strongly associated with mortality and poor neurological outcomes in a small cohort of patients treated with extracorporeal membrane oxygenation.

Accumulating evidence supports an effect of physician gender (or sex, a surrogate used in many studies) on important patient outcomes such as death, complications, and hospital length of stay. Recent studies suggest that these effects result from the gender diversity of the team rather than individual physician gender. Here, we reflect on the potential mechanisms of an effect of physician gender on patient outcomes.
