Recovery is an abstract quantity the definition of which varies according to the pre-dilection of individual institutions, clinicians or patients. While traditionally focused on immediate postoperative restitution of function and readiness for discharge, recovery assessment has progressively expanded its focus to include other clinically relevant time periods, each of which is influenced by specific factors. Assessment tools have progressed from assessing one dimension of recovery, such as physiological variables, to multidimensional assessment of physical, nociceptive, emotive, functional and cognitive performance. They should be validated ideally for repeat measures and should provide real-time recovery data, as recovery can be viewed as a continuous process.

Peri-operative anaemia, blood loss and allogeneic blood transfusion are associated with increased postoperative morbidity and mortality, and prolonged hospital stay. A multidisciplinary, multimodal, individualised strategy, collectively termed 'patient blood management', may reduce or eliminate allogeneic blood transfusion and improve outcomes. ⋯ This review focuses on the pre-operative evaluation of erythropoiesis, coagulation status and platelet function. Where possible, evidence is graded systematically and recommended therapies follow recently published consensus guidance.

Patients are frequently malnourished or are at risk of malnutrition before surgery. Peri-operative nutritional support can improve their outcomes. This review focuses on new developments in peri-operative nutrition, including: patient preparation and pre-operative fasting; the role of nutritional supplementation; the optimal route and timing of nutrient delivery; and the nutritional management of specific groups including critically ill, obese and elderly patients.

While specialist pre-operative assessment is not new, its focus has evolved in response to more operations and changes in the surgical population. Patients are older and have more long-term medical comorbidities. ⋯ Pre-operative clinics have a central role in shared decision-making, coordinating and planning care before, during and after surgery, including rehabilitation and discharge planning. Multiple specialties need to work together to deliver quality patient-centred care.

'Enhanced recovery after surgery' protocols implement a series of peri-operative interventions intended to improve recovery after major operations, one aspect of which is fluid management. The pre-operative goal is to prepare a hydrated, euvolaemic patient by avoiding routine mechanical bowel preparation and by encouraging patients to drink clear liquids up to two hours before induction of anaesthesia. ⋯ The postoperative goal is eating and drinking without intravenous fluid infusions. Postoperative oliguria should be expected and accepted, as urine output does not indicate overall fluid status.
