Article 25 of the United Nations' Universal Declaration of Human Rights enshrines the right to health and well-being for every individual. However, universal access to high-quality healthcare remains the purview of a handful of wealthy nations. This is no more apparent than in peri-operative care, where an estimated five billion individuals lack access to safe, affordable and timely surgical care. ⋯ Current peri-operative research and clinical guidance often fail to acknowledge these system-level deficits and therefore have limited applicability in low-resource settings. In this manuscript, the authors priority-set the need for equitable access to high-quality peri-operative care and analyse the system-level contributors to excess peri-operative mortality rates, a key marker of quality of care. To provide examples of how research and investment may close the equity gap, a modified Delphi method was adopted to curate and appraise interventions which may, with subsequent research and evaluation, begin to address the barriers to high-quality peri-operative care in low- and middle-income countries.

Enhanced postoperative recovery programmes (ERAS) were developed about 20 years ago based on improved understanding of the pathophysiology of postoperative recovery within an integrated multidisciplinary approach. The results across surgical procedures have been extremely positive with a reduction in hospitalisation and medical complications, without increased re-admission rates. However, several challenges lie ahead including improved implementation of existing scientific evidence, increased focus on post-discharge recovery problems and a need for improved design of future ERAS studies. ⋯ These efforts should focus on: the inflammatory and neurohumoral surgical stress responses; fluid management; pain management; blood management; mechanisms of orthostatic intolerance; postoperative cognitive dysfunction; risk factors for thrombo-embolic complications; and mechanisms and prevention of postoperative ileus. Finally, more focus should be made on the different barriers to post-discharge functional recovery and the choice of (pre- and postoperative) rehabilitation. These efforts should be made on a procedure-specific as well as on a patient-specific basis.

Observational Study
The association between genome-wide polymorphisms and chronic postoperative pain: a prospective observational study.
Chronic postoperative pain is common and can have a negative impact on quality of life. Recent studies show that genetic risk factors are likely to play a role, although only gene-targeted analysis has been used to date. This is the first genome-wide association study to identify single-nucleotide polymorphisms associated with the development of chronic postoperative pain based on two independent cohorts. ⋯ A single-nucleotide polymorphism in NAV3 was significantly replicated with chronic postoperative pain in the replication cohort (p = 0.009). Meta-analysis revealed that two loci (IQGAP1 and CRTC3) were significantly associated with chronic postoperative pain at 3 months (IQGAP1 p = 3.93 × 10-6 β = 2.3863, CRTC3 p = 2.26 × 10-6 , β = 2.4209). The present genome-wide association study provides initial evidence for genetic risk factors of chronic postoperative pain and supports follow-up studies.

Delirium is a common complication following hip fracture surgery. We introduced a peri-operative care bundle that standardised management in the emergency department, operating theatre and ward. This incorporated: use of fascia iliaca blocks; rationalisation of analgesia; avoidance of drugs known to trigger delirium; a regular education program for staff; and continuous auditing of compliance. ⋯ There was no difference between groups for the secondary outcome measures (measured at 30 days postoperatively) including: all-cause mortality; composite morbidity; institutionalisation; and walking status. During the study period, compliance with elements of the care bundle improved in the emergency department (49 patients (33%) compared with 85 patients (59%); p < 0.001) and anaesthetic department (40 patients (27%) compared with 104 patients (69%); p < 0.001), while orthogeriatrics maintained a high level of compliance (140 patients (93%) compared with 143 patients (95%); p = 0.45). There was a clinically and statistically significant reduction in the incidence of delirium following hip fracture surgery in patients treated with a multidisciplinary care bundle.
