This review on shared decision-making comes at a time when international healthcare policy, domestic law and patient expectation demand a bringing-together of the patient's values and preferences with the physician's expertise to determine the best bespoke care package for the individual. Despite robust guidance in terms of consent, the anaesthetic community have lagged behind in terms of embracing the patient-focused rather than doctor-focused aspects of shared decision-making. For many, confusion has arisen due to a conflation of informed consent, risk assessment, decision aids and shared decision-making. ⋯ As patients have already decided to proceed with therapy or investigation and may be more concerned about the surgery than the anaesthesia, it is often assumed they will accept whatever anaesthetic is offered and defer to the clinician's expertise - without discussion. Furthermore, shared decision-making does not stop at time of anaesthesia for the peri-operative physician. It continues until discharge and requires the anaesthetist to engage in shared decision-making for prescribing and deprescribing peri-operative medicines.

Peri-operative hyperglycaemia, whether the cause is known diabetes, undiagnosed diabetes or stress hyperglycaemia, is a risk factor for harm, increased length of stay and death. There is increasing evidence that peri-operative hyperglycaemia is a modifiable risk factor, and many of the interventions required to improve the outcome of surgery must be instituted before the actual surgical admission. These interventions depend on communication and collaboration within the multidisciplinary team along each stage of the patient journey to ensure that integration of care occurs across the whole of the patient-centred care pathway.

Review
Psychological factors, prehabilitation and surgical outcomes: evidence and future directions.
The pre-operative optimisation of comorbidities is increasingly recognised as an important element of the pre-operative pathway. These efforts have primarily focused on physical comorbidities such as anaemia and the optimisation of exercise and nutrition. However, there is a growing recognition of the importance of psychological morbidity. ⋯ This has led to the emergence of psychological prehabilitation and the trimodal approach to prehabilitation, incorporating psychological intervention as well as exercise and nutritional optimisation. However, there is currently insufficient evidence to be sure that pre-operative psychological interventions are of benefit, or which interventions are most effective, because their impact has been mixed. There is an urgent need for high quality, contemporaneous prospective trials with baseline psychological evaluation, well-described interventions and agreement on the most appropriate psychological, quality of life and physiological outcomes measures.

Pre-operative nutrition therapy is increasingly recognised as an essential component of surgical care. The present review has been formatted using Simon Sinek's Golden Circle approach to explain 'why' avoiding pre-operative malnutrition and supporting protein anabolism are important goals for the elective surgical patient, 'how' peri-operative malnutrition develops leading in part to a requirement for pre-operative anabolic preparation, and 'what' can be done to avoid pre-operative malnutrition and support anabolism for optimal recovery.

It is widely recognised that prolonged fasting for elective surgery in both children and adults serves no purpose, adversely affects patient well-being and can be detrimental. Although advised fasting times for solids remain unchanged, there is good evidence to support a 1-h fast for children, with no increase in risk of pulmonary aspiration. ⋯ As in children, there is no increase in risk of pulmonary aspiration. Further data are required to guide best practice in patients with diabetes.
