RESUMO
This retrospective cohort study on adults undergoing colectomy from 2010 to 2019 used linked primary (Clinical Practice Research Datalink), and secondary (Hospital Episode Statistics) care data to determine the prevalence of persistent postoperative opioid use following colectomy, stratified by pre-admission opioid exposure, and identify associated predictors. Based on pre-admission opioid exposure, patients were categorised as opioid-naïve, currently exposed (opioid prescription 0-6 months before admission) and previously exposed (opioid prescription within 7-12 months before admission). Persistent postoperative opioid use was defined as requiring an opioid prescription within 90 days of discharge, along with one or more opioid prescriptions 91-180 days after hospital discharge. Multivariable logistic regression analyses were conducted to obtain odds ratios for predictors of persistent postoperative opioid use. Among the 93,262 patients, 15,081 (16.2%) were issued at least one opioid prescription within 90 days of discharge. Of these, 6791 (45.0%) were opioid-naïve, 7528 (49.9%) were currently exposed and 762 (5.0%) were previously exposed. From the whole cohort, 7540 (8.1%) developed persistent postoperative opioid use. Patients with pre-operative opioid exposure had the highest persistent use: 5317 (40.4%) from the currently exposed group; 305 (9.8%) from the previously exposed group; and 1918 (2.5%) from the opioid-naïve group. The odds of developing persistent opioid use were higher among individuals who used long-acting opioid formulations in the 180 days before colectomy than those who used short-acting formulations (odds ratio 3.41 (95%CI 3.07-3.77)). Predictors of persistent opioid use included: previous opioid exposure; high deprivation index; multiple comorbidities; use of long-acting opioids; white race; and open surgery. Minimally invasive surgical approaches were associated with lower odds of persistent opioid use and may represent a modifiable risk factor.

The procedure-specific postoperative pain management (PROSPECT) working group develops evidence-based pain management recommendations. PROSPECT methodology is unique and rigorous. However, several limitations were recognised that needed to be addressed, and several new factors were identified that improved PROSPECT methodology. The aim of this article is to present updated PROSPECT methodology for development of recommendations for procedure-specific pain management, focusing on the methodological revisions we will implement. In future, included randomised clinical trials will need to be prospectively registered on a publicly accessible clinical trials database and the study design, including the primary outcome in the registration, should coincide with that in the published manuscript. Placebo-controlled studies in which the analgesic intervention of interest is solely paracetamol, non-steroidal anti-inflammatory drugs, cyclo-oxygenase-2-specific inhibitors or opioids will not be included. Studies comparing one drug in a particular class with another in the same class will also not be included. Future projects will use the Cochrane Collaboration risk of bias tool for quality of reporting of methodology and results. A modified Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach will be used for grading of level of evidence and strength of recommendations. Finally, the updated PROSPECT methodology addresses several other limitations and implements new factors that all add rigour and transparency to developing procedure-specific pain management recommendations.

Prescription of modified-release opioids for acute postoperative pain is widespread despite evidence to show their use may be associated with an increased risk of adverse effects. This systematic review and meta-analysis aimed to examine the available evidence on the safety and efficacy of modified-release, compared with immediate-release, oral opioids for postoperative pain in adults. We searched five electronic databases from 1 January 2003 to 1 January 2023. Published randomised clinical trials and observational studies on adults who underwent surgery which compared those who received oral modified-release opioids postoperatively with those receiving oral immediate-release opioids were included. Two reviewers independently extracted data on the primary outcomes of safety (incidence of adverse events) and efficacy (pain intensity, analgesic and opioid use, and physical function) and secondary outcomes (length of hospital stay, hospital readmission, psychological function, costs, and quality of life) up to 12 months postoperatively. Of the eight articles included, five were randomised clinical trials and three were observational studies. The overall quality of evidence was low. Modified-release opioid use was associated with a higher incidence of adverse events (n = 645, odds ratio (95%CI) 2.76 (1.52-5.04)) and worse pain (n = 550, standardised mean difference (95%CI) 0.2 (0.04-0.37)) compared with immediate-release opioid use following surgery. Our narrative synthesis concluded that modified-release opioids showed no superiority over immediate-release opioids for analgesic consumption, length of hospital stay, hospital readmissions or physical function after surgery. One study showed that modified-release opioid use is associated with higher rates of persistent postoperative opioid use compared with immediate-release opioid use. None of the included studies reported on psychological function, costs or quality of life.

BACKGROUND: Burnout arising from chronic work-related stress is endemic among surgeons in the UK. Identification of contributory and modifiable psychosocial work characteristics could inform risk reduction activities. AIMS: We aimed to assess the extent to which surgeons' psychosocial working conditions met aspirational Management Standards delineated by the UK Health and Safety Executive, draw comparisons with national general workforce benchmarks and explore associations with burnout. METHODS: Surgeons (Nâ =â 536) completed the Management Standards Indicator Tool and a single-item measure of burnout. Descriptive data were computed for each Standard, independent t-tests were used to examine differences between trainees and consultants, and hierarchical linear regression was applied to explore relations between psychosocial work environment quality and burnout. RESULTS: Psychosocial work environment quality fell short of each Management Standard. Trainee surgeons (nâ =â 214) reported significantly poorer psychosocial working conditions than consultant surgeons (nâ =â 322) on the control, peer support and change Standards. When compared with UK workforce benchmarks, trainees' psychosocial working conditions fell below the 10th percentile on four Standards and below the 50th percentile on the remainder. Consultant surgeons were below the 50th percentile on five of the seven Standards. Psychosocial working conditions accounted for 35% of the variance in burnout over that accounted for by socio- and occupational-demographic characteristics. CONCLUSIONS: Surgeons' psychosocial working conditions were poor in comparison with benchmark data and associated with burnout. These findings suggest that risk management activities based on the Management Standards approach involving modification of psychosocial working conditions would help to reduce burnout in this population.

BACKGROUND: Burnout is endemic in surgeons in the UK and linked with poor patient safety and quality of care, mental health problems, and workforce sustainability. Mechanisms are required to facilitate the efficient identification of burnout in this population. Multi-item measures of burnout may be unsuitable for this purpose owing to assessment burden, expertise required for analysis, and cost. AIMS: To determine whether surgeons in the UK reporting burnout on the 22-item Maslach Burnout Inventory (MBI) can be reliably identified by a single-item measure of burnout. METHODS: Consultant (n = 333) and trainee (n = 217) surgeons completed the MBI and a single-item measure of burnout. We applied tests of discriminatory power to assess whether a report of high burnout on the single-item measure correctly classified MBI cases and non-cases. RESULTS: The single-item measure demonstrated high discriminatory power on the emotional exhaustion burnout domain: the area under the curve was excellent for consultants and trainees (0.86 and 0.80), indicating high sensitivity and specificity. On the depersonalisation domain, discrimination was acceptable for consultants (0.76) and poor for trainees (0.69). In contrast, discrimination was acceptable for trainees (0.71) and poor for consultants (0.62) on the personal accomplishment domain. CONCLUSIONS: A single-item measure of burnout is suitable for the efficient assessment of emotional exhaustion in consultant and trainee surgeons in the UK. Administered regularly, such a measure would facilitate the early identification of at-risk surgeons and swift intervention, as well as the monitoring of group-level temporal trends to inform resource allocation to coincide with peak periods.

Opioid misuse is now considered a major public health epidemic in North America, with substantial social and financial consequences. As well as socio-economic and commercial drivers, modifiable risk-factors that have resulted in this crisis have been identified. The purpose of this study was to identify whether, within England, modifiable drivers for persistent postoperative opioid use were present. This was a retrospective cohort study of practice at 14 National Health Service hospitals across England. Data were collected retrospectively and validated for adult patients undergoing elective intermediate and major or complex major general surgical procedures between 1 and 31 March 2019. Of the 509 patients enrolled from 14 centres, 499 were included in the data analysis. In total, 31.5% (157/499) patients were in the intermediate surgery cohort and 68.5% (342/499) were in the major or complex major surgery cohort, with 21.0% (33/157) and 21.6% (74/342) discharged with opioid medicines to be taken at regular intervals, respectively. There were similar median oral morphine equivalent doses prescribed at discharge. Of patients prescribed regular opioid medicines, 76.6% (82/107) had a specified duration at discharge. However, 72.9% (78/107) had no written deprescribing advice on discharge. Similarly, of patients prescribed 'when required' opioids, 59.6% (93/156) had a specified duration of their prescription and 33.3% (52/156) were given written deprescribing advice. This study has identified a pattern of poor prescribing practices, a lack of guidance and formal training at individual institutions and highlights opportunities for improvement in opioid-prescribing practices within England.

This international multidisciplinary consensus statement was developed to provide balanced guidance on the safe peri-operative use of opioids in adults. An international panel of healthcare professionals evaluated the literature relating to postoperative opioid-related harm, including persistent postoperative opioid use; opioid-induced ventilatory impairment; non-medical opioid use; opioid diversion and dependence; and driving under the influence of prescription opioids. Recommended strategies to reduce harm include pre-operative assessment of the risk of persistent postoperative opioid use; use of an assessment of patient function rather than unidimensional pain scores alone to guide adequacy of analgesia; avoidance of long-acting (modified-release and transdermal patches) opioid formulations and combination analgesics; limiting the number of tablets prescribed at discharge; providing deprescribing advice; avoidance of automatic prescription refills; safe disposal of unused medicines; reducing the risk of opioid diversion; and better education of healthcare professionals, patients and carers. This consensus statement provides a framework for better prescribing practices that could help reduce the risk of postoperative opioid-related harm in adults.

BACKGROUND: This is the fourth updated Enhanced Recovery After Surgery (ERAS®) Society guideline presenting a consensus for optimal perioperative care in colorectal surgery and providing graded recommendations for each ERAS item within the ERAS® protocol. METHODS: A wide database search on English literature publications was performed. Studies on each item within the protocol were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts and examined, reviewed and graded according to Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. RESULTS: All recommendations on ERAS® protocol items are based on best available evidence; good-quality trials; meta-analyses of good-quality trials; or large cohort studies. The level of evidence for the use of each item is presented accordingly. CONCLUSIONS: The evidence base and recommendation for items within the multimodal perioperative care pathway are presented by the ERAS® Society in this comprehensive consensus review.

BACKGROUND: During the last two decades, an increasing number of bariatric surgical procedures have been performed worldwide. There is no consensus regarding optimal perioperative care in bariatric surgery. This review aims to present such a consensus and to provide graded recommendations for elements in an evidence-based "enhanced" perioperative protocol. METHODS: The English-language literature between January 1966 and January 2015 was searched, with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohort studies. Selected studies were examined, reviewed and graded. After critical appraisal of these studies, the group of authors reached a consensus recommendation. RESULTS: Although for some elements, recommendations are extrapolated from non-bariatric settings (mainly colorectal), most recommendations are based on good-quality trials or meta-analyses of good-quality trials. CONCLUSIONS: A comprehensive evidence-based consensus was reached and is presented in this review by the enhanced recovery after surgery (ERAS) Society. The guidelines were endorsed by the International Association for Surgical Metabolism and Nutrition (IASMEN) and based on the evidence available in the literature for each of the elements of the multimodal perioperative care pathway for patients undergoing bariatric surgery.

BACKGROUND: The present interdisciplinary consensus review proposes clinical considerations and recommendations for anaesthetic practice in patients undergoing gastrointestinal surgery with an Enhanced Recovery after Surgery (ERAS) programme. METHODS: Studies were selected with particular attention being paid to meta-analyses, randomized controlled trials and large prospective cohort studies. For each item of the perioperative treatment pathway, available English-language literature was examined and reviewed. The group reached a consensus recommendation after critical appraisal of the literature. RESULTS: This consensus statement demonstrates that anaesthesiologists control several preoperative, intraoperative and postoperative ERAS elements. Further research is needed to verify the strength of these recommendations. CONCLUSIONS: Based on the evidence available for each element of perioperative care pathways, the Enhanced Recovery After Surgery (ERAS®) Society presents a comprehensive consensus review, clinical considerations and recommendations for anaesthesia care in patients undergoing gastrointestinal surgery within an ERAS programme. This unified protocol facilitates involvement of anaesthesiologists in the implementation of the ERAS programmes and allows for comparison between centres and it eventually might facilitate the design of multi-institutional prospective and adequately powered randomized trials.

In healthy surgical patients, preoperative fasting and major surgery induce development of insulin resistance (IR). IR can be present in up to 41% of obese patients without diabetes and this can rise in the postoperative period, leading to an increased risk of postoperative complications. Inflammation is implicated in the aetiology of IR. This review examines obesity-associated IR and its implications for the surgical patient. Searches of the Medline and Science Citation Index databases were performed using various key words in combinations with the Boolean operators AND, OR and NOT. Key journals, nutrition and metabolism textbooks and the reference lists of key articles were also hand searched. Adipose tissue has been identified as an active endocrine organ and the chemokines secreted as a result of macrophage infiltration have a role in the pathogenesis of IR. Visceral adipose tissue appears to be the most metabolically active, although results across studies are not consistent. Results from animal and human studies often provide conflicting results, which has rendered the pursuit of a common mechanistic pathway challenging. Obesity-associated IR appears, in part, to be related to inflammatory changes associated with increased adiposity. Postoperatively, the surgical patient is in a proinflammatory state, so this finding has important implications for the obese surgical patient.

BACKGROUND: The present article has been written to convey concepts of anaesthetic care within the context of an Enhanced Recovery After Surgery (ERAS) programme, thus aligning the practice of anaesthesia with the care delivered by the surgical team before, during and after surgery. METHODS: The physiological principles supporting the implementation of the ERAS programmes in patients undergoing major abdominal procedures are reviewed using an updated literature search and discussed by a multidisciplinary group composed of anaesthesiologists and surgeons with the aim to improve perioperative care. RESULTS: The pathophysiology of some key perioperative elements disturbing the homoeostatic mechanisms such as insulin resistance, ileus and pain is here discussed. CONCLUSIONS: Evidence-based strategies aimed at controlling the disruption of homoeostasis need to be evaluated in the context of ERAS programmes. Anaesthesiologists could, therefore, play a crucial role in facilitating the recovery process.

Lymphovascular invasion (LVI) in T1 esophagogastric adenocarcinoma may predict risk of recurrence despite definitive treatment with surgery or endoscopic resection. Podoplanin and CD34 are emerging biomarkers of lymphatic and blood vessel invasion, respectively, and could be adopted to refine LVI assessment. A consecutive series of 65 patients with T1 adenocarcinomas diagnosed at Nottingham University Hospitals were investigated. T1 tumors from 43/65 patients who received primary surgery only were suitable for LVI evaluation by hematoxylin and eosin (H&E) staining as well as by CD34 and Podoplanin immunohistochemistry. LVI was correlated to clinicopathological features and recurrence free survival. H&E staining detected LVI in 11.6% (5/43) of T1 tumors. CD34 and Podoplanin immunohistochemistry significantly improved LVI detection to 25.6% (11/43). Compared with LVI by H&E, immunohistochemical evaluation of blood vessel invasion (CD34) or lymphatic vessel invasion (Podoplanin) was significantly associated with higher grade (P = 0.005), submucosal invasion (T1b) (P = 0.018), lymph node positivity (N1) (P = 0.029) and poor recurrence free survival (P = 0.0003). Our study provides evidence that CD34 and Podoplanin immunohistochemistry could improve LVI detection and allow better prognostication of patients and optimum selection of definitive treatment. Larger multicenter studies are required for further validation that could have significant clinical implications.

Fluid management during critical illness is a dynamic process that may be conceptualized as occurring in four phases: rescue, optimization, stabilization, and de-escalation (mobilization). The selection and administration of resuscitation fluids is one component of this complex physiological sequence directed at restoring depleted intravascular volume. Presently, the selection of i.v. fluid is usually dictated more by local practice patterns than by evidence. The debate on fluid choice has primarily focused on evaluating outcome differences between 'crystalloids vs colloids'. More recently, however, there is interest in examining outcome differences based on the chloride content of crystalloid solutions. New insights into the conventional Starling model of microvascular fluid exchange may explain that the efficacy of colloids in restoring and maintaining depleted intravascular volume is only moderately better than crystalloids. A number of investigator-initiated, high-quality, randomized controlled trials have demonstrated that modest improvements in short-term physiological endpoints with colloids have not translated into better patient-centred outcomes. In addition, there is substantial evidence that certain types of fluids may independently worsen patient-centred outcomes. These include hydroxyethyl starch and albumin solutions in selected patient populations. There is no evidence to support the use of other colloids. The use of balanced salt solutions in preference to 0.9% saline is supported by the absence of harm in large observational studies. However, there is no compelling randomized trial-based evidence demonstrating improved clinical outcomes with the use of balanced salt solutions compared with 0.9% saline at this time.

BACKGROUND: This study aims to study changes in blood volume after 1 litre infusions of Gelofusine(®) [4% succinylated gelatine in 0.7% saline, weight-average molecular weight (MWw) 30 kDa] and Voluven(®) (6% hydroxyethyl starch in 0.9% saline, MWw 130 kDa) in the presence of increased capillary permeability. METHODS: In this randomized double-blind study, adults undergoing laparoscopic cholecystectomy received 1 litre of Gelofusine(®) (n=12) or Voluven(®) (n=13) over 1 h at the induction of anaesthesia. No other fluids were given. Haematocrit, serum electrolytes, and osmolality were measured before infusion and hourly thereafter for 4 h. Changes in blood volume were calculated from changes in haematocrit. The urinary albumin:creatinine ratio (ACR) was measured before and after operation. RESULTS: Baseline parameters before the two infusions were similar (P>0.050). The urinary ACR increased significantly after operation after Gelofusine(®) (P=0.011) and Voluven(®) (P=0.002), indicating increased capillary permeability. Voluven(®) produced a greater increase in serum chloride concentration (P=0.028) and a larger decrease in strong ion difference (P=0.009) than Gelofusine(®). There were no significant differences in changes in haematocrit (P=0.523) and blood volume (P=0.404) over the study period when the two infusions were compared, nor were there any differences in serum sodium, potassium, bicarbonate, and albumin concentrations (P>0.050). Urine output, sodium concentration, and osmolality were similar after the two infusions (P>0.050). CONCLUSIONS: The blood volume-expanding effects of the two colloids were not significantly different, despite the increase in postoperative urinary ACR and the 100 kDa difference in MWw.
