Pre-operative optimisation is a heterogenous group of interventions aimed at improving peri-operative outcomes. To understand the evidence for pre-operative optimisation in the developing world, we systematically reviewed Cochrane reviews on the topic according to the Human Developmental Index (HDI) of the country where patient recruitment occurred. We used summary statistics and cartograms to describe the HDI, year of publication, timing of pre-operative intervention and risk of bias associated with each included trial. ⋯ Half of the world's population live in low- and middle-HDI countries. This population is poorly represented in systematically reviewed evidence on pre-operative optimisation. Multinational trials increase the knowledge contribution from low- and middle-HDI countries and decrease risk of bias in systematic reviews.

In this paper I explain why I think that most of the models that predict postoperative mortality should not be used when we're talking to patients about postoperative survival. Available models are isolated in time (from survival in the present) and space (from survival outside hospital). We know a lot about survival outside hospitals, with sufficient detail that we can discriminate between a man born in 1975 vs. 1976, or a woman aged 64 years vs. 65 years. ⋯ We are also intervening earlier in progressive diseases, knowing that people are living long enough to experience harm from their progression. There is an evolving conflict between operating on older people and operating on younger people. Who has most to gain from the operation and who has most to gain from peri-operative critical care? Do we prioritise on reducing death now, in patients with relatively short life expectancies, or do we invest in the long-term survival of patients with relatively low rates of dying now? This conundrum is not informed by current risk models, with their focus on one to three postoperative months: we need to know survival outside hospital to gauge the value of what we do in hospital.

Although the concept of pre-operative optimisation is traditionally applied to elective surgery, there is ample opportunity to apply similar principles to patients undergoing emergency laparotomy. The key challenge is achieving meaningful improvements in a patient's condition without introducing delays to time-sensitive surgery, which may be required in a matter of hours. ⋯ Optimising the patient's condition is less about improving long-term pathology, and more about correcting physiological derangement, such as electrolyte and fluid balance, blood loss, prompt treatment of sepsis, and ensuring appropriate continuation of medication in the peri-operative period. Optimising the care pathway involves ensuring that the system is designed to deliver reliably the appropriate interventions, such as prompt antibiotics, and access to computed tomography scanning and the operating theatre with minimal delay.

With increasing life expectancy and technological advancement, provision of anaesthesia for elderly patients has become a significant part of the overall case-load. These patients are unique, not only because they are older with more propensity for comorbidity but a decline in physiological reserve and cognitive function invariably accompanies ageing; this can substantially impact peri-operative outcome and quality of recovery. Furthermore, it is not only morbidity and mortality that matters; quality of life is also especially relevant in this vulnerable population. ⋯ The assessment of frailty has a central role in the pre-operative evaluation of the elderly. Other essential domains include optimisation of nutritional status, assessment of baseline cognitive function and proper approach to patient counselling and the decision-making process. Anaesthetists should be proactive in multidisciplinary care to achieve better outcomes; they are integral to the process.

Quality of life after critical illness is becoming increasingly important as survival improves. Various measures have been used to study the quality of life of patients discharged from intensive care. We systematically reviewed validated measures of quality of life and their results. ⋯ Quality of life improved for one year after hospital discharge. The aspects of life that improved most were physical function, physical role, vitality and social function. However, these domains were also the least likely to recover to population norms as they were more profoundly affected by critical illness.
