Abstract
INTRODUCTION Accurate risk scoring in emergency general surgery (EGS) is vital for consent and resource allocation. The emergency surgery score (ESS) has been validated as a reliable preoperative predictor of postoperative outcomes in EGS but has been studied only in the US population. Our primary aim was to perform an external validation study of the ESS in a UK population. Our secondary aim was to compare the accuracy of ESS and National Emergency Laparotomy Audit (NELA) scores. METHODS We conducted an observational cohort study of adult patients undergoing emergency laparotomy over three years in two UK centres. ESS was calculated retrospectively. NELA scores and all other variables were obtained from the prospectively collected Emergency Laparotomy and Laparoscopic Scottish Audit (ELLSA) database. The primary and secondary outcomes were 30-day mortality and postoperative intensive care unit (ICU) admission, respectively. RESULTS A total of 609 patients were included. Median age was 65 years, 52.7% were female, the overall mortality was 9.9% and 23.8% were admitted to ICU. Both ESS and NELA were equally accurate in predicting 30-day mortality (c-statistic=0.78 (95% confidence interval (CI), 0.71-0.85) for ESS and c-statistic=0.83 (95% CI, 0.77-0.88) for NELA, p=0.196) and predicting postoperative ICU admission (c-statistic=0.76 (95% CI, 0.71-0.81) for ESS and 0.80 (95% CI, 0.76-0.85) for NELA, p=0.092). CONCLUSIONS In the UK population, ESS and NELA both predict 30-day mortality and ICU admission with no statistically significant difference but with higher c-statistics for NELA score. Both scores have certain advantages, with ESS being validated for a wider range of outcomes.

Influencing factors in surgical decision-making: a qualitative analysis of colorectal surgeons' experiences of postoperative complications. Colorectal Dis 2024; 26:987-993. [PMID: 38485203 DOI: 10.1111/codi.16943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 01/25/2024] [Accepted: 02/21/2024] [Indexed: 05/26/2024]
Abstract
AIM When making anastomotic decisions in rectal cancer surgery, surgeons must consider the risk of anastomotic leakage, which bears implications for the patient's quality of life, cancer recurrence and, potentially, death. The aim of this study was to investigate the views of colorectal surgeons on how their individual attributes (e.g. experience, personality traits) may influence their decision-making and experience of complications. METHOD This qualitative study used individual interviews for data collection. Purposive sampling was used to invite certified UK-based colorectal surgeons to participate. Participants were recruited until ongoing data review indicated no new codes were generated, suggesting data sufficiency. Data were analysed thematically following Braun and Clarke's six-step framework. RESULTS Seventeen colorectal surgeons (eight female, nine male) participated. Two key themes with relevant subthemes were identified: (1) personal attributes influencing variation in decision-making (e.g. demographics, personality) and (2) the influence of complications on decision-making. Surgeons described variation in the management of complications based upon their personal attributes, which included factors such as gender, experience and subspeciality interests. Surgeons described the detrimental impact of anastomotic leakage on their mental and physical health. Experience of anastomotic leakage influences future decision-making and is associated with changes in practice even when a technical error is not identified. CONCLUSION Colorectal surgeons consider anastomotic leaks to be personal 'failures', which has a negative impact on surgeon welfare. Better understanding of how surgeons make difficult decisions, and how surgeons respond to and learn from complications, is necessary to identify 'personalized' methods of supporting surgeons at all career stages, which may improve patient outcomes.

Dissecting the surgeon's personality: cross-cultural comparisons in Western Europe. Colorectal Dis 2024. [PMID: 38687763 DOI: 10.1111/codi.16993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 01/16/2024] [Accepted: 03/06/2024] [Indexed: 05/02/2024]
Abstract
AIM The surgeon's personality contributes to variation in surgical decision-making. Previous work on surgeon personality has largely been reserved to Anglo-Saxon studies, with limited international comparisons. In this work we built upon recent work on gastrointestinal surgeon personality and aimed to detect international variations. METHOD Gastrointestinal surgeons from the UK and the Netherlands were invited to participate in validated personality assessments (44-item, 60-item Big Five Inventory; BFI). These encompass personality using five domains (open-mindedness, conscientiousness, extraversion, agreeableness and negative emotionality) with three subtraits each. Mean differences in domain factors were calculated between surgeon and nonsurgeon populations from normative data using independent-samples t-tests, adjusted for multiple testing. The items from the 44-item and 60-item BFI were compared between UK and Dutch surgeons and classified accordingly: identical (n = 16), analogous (n = 3), comparable (n = 12). RESULTS UK (n = 78, 61.5% male) and Dutch (n = 280, 65% male) gastrointestinal surgeons had marked differences in the domains of open-mindedness, extraversion and agreeableness compared with national normative datasets. Moreover, although surgeons had similar levels of emotional stability, country of work influenced differences in specific BFI items. For example, Netherlands-based surgeons scored highly on questions related to sociability and organization versus UK-based surgeons who scored highly on creative imagination (p < 0.0001). CONCLUSION In a first cross-cultural setting, we identified country-specific personality differences in gastrointestinal surgeon cohorts across domain and facet levels. Given the variation between Dutch and UK surgeons, understanding country-specific data could be useful in guiding personality research in healthcare. Furthermore, we advocate that future work adopts consensus usage of the five factor model.

Patient-reported impact of emergency laparotomy on employment and health status 1 year after surgery. Langenbecks Arch Surg 2023; 408:378. [PMID: 37749405 DOI: 10.1007/s00423-023-03104-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 09/09/2023] [Indexed: 09/27/2023]
Abstract
BACKGROUND Whilst there has been significant improvement in mortality outcomes after emergency laparotomy, there is little information on longer term outcomes in the year after discharge. The main aim of the study was to assess the impact that an emergency laparotomy has on patients' and employment and health status 1 year after surgery. METHODS This study was a questionnaire study conducted in a single centre district general hospital of patients who had undergone an emergency laparotomy between October 2015 and December 2016. Patients were included according to the National Emergency Laparotomy Audit criteria. At screening, patients who were alive at 1 year and had the capacity to consent were approached between January and December 2017. Patients underwent a researcher-led telephone interview using a semi-structured questionnaire to assess the impact of emergency laparotomy on overall, general and physical health (Glasgow Benefit Inventory) as well as employment status. The symptoms that patients experienced and their impact were also recorded. RESULTS Forty-two patients responded to and completed the questionnaire. Just over one-third of patients experienced a deterioration in their general or physical health and 21% of patients experienced a change in employment. Factors which significantly impacted on health status were stoma issues, postoperative morbidity and a change in employment (p < 0.05). The main symptoms which patients identified as being troublesome were altered bowel habit and stoma issues with a resultant social and psychological impact. CONCLUSIONS One-third of patients experienced a deterioration in their psychosocial and physical health status as well as a change in employment during the first-year postsurgery. Larger research studies are required to define the impact of emergency laparotomy on patients in the longer term and more research is needed to improve perioperative rehabilitation in the postoperative period to ensure optimal functional gain after technically successful surgery.

Poor outcomes in patients with sepsis undergoing emergency laparotomy and laparoscopy are attenuated by faster time to care measures. Colorectal Dis 2023; 25:1888-1895. [PMID: 37545127 DOI: 10.1111/codi.16702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 05/12/2023] [Accepted: 06/19/2023] [Indexed: 08/08/2023]
Abstract
AIM Emergency laparotomy and laparoscopy (EmLap) are amongst the commonest surgical procedures, with high prevalence of sepsis and hence poorer outcomes. However, whether time taken to receive care influences outcomes in patients requiring antibiotics for suspected infection remains largely unexplored. The aim of this work was to determine whether (1) time to care contributes to outcome differences between patients with and without suspected infection and (2) its impact on outcomes only amongst those with suspected infection. METHOD Clinical information was retrospectively obtained from the 2017-2018 Emergency Laparotomy and Laparoscopic Scottish Audit (ELLSA). Time to care referred to six temporal variables describing radiological investigation, anaesthetic triage and surgical management. Outcome measures [mortality, readmission, hospital death, postoperative destination and length of stay (LoS)] were compared using adjusted and unadjusted regression analyses to determine whether the outcome differences could be explained by faster or slower time to care. RESULTS Amongst 2243 EmLap patients [median age 65 years (interquartile range 51-75 years), 51.1% female], 892 (39.77%) received antibiotics for suspected infection. Although patients with suspected infection had faster time to care (all p ≤ 0.001) and worse outcomes compared with those who did not, outcome differences were not statistically significant when accounted for time (all p > 0.050). Amongst those who received antibiotics, faster time to care was also associated with decreased risk of postoperative intensive care unit (ICU) stay and shorter LoS (all p < 0.050). CONCLUSION Worse outcomes associated with infection in EmLap patients were attenuated by faster time to care, which additionally reduced the LoS and ICU stay risk amongst those with suspected infection.

Abstract
Social media has revolutionized how we design, deliver, and disseminate surgical research for the better. The rise of collaborative research groups has been a major contributor to and beneficiary of social media, leading to increased involvement from clinicians, medical students, healthcare professionals, patients, and industry. Everyone benefits from collaborative research by widening access and participation and delivering more impactful research with increasing validity of results applicable to global populations. Now more than ever, the international surgical community is engaged in the process of surgical research, including the role of interdisciplinary collaboration. Patient groups are also central to the process of collaboration. By delivering increasingly relevant research, and by asking pertinent research questions that patients value, higher-impact research is more likely to directly lead to clinical change. From an academic perspective, hierarchies have flattened, facilitating the inclusion of anyone who is interested in contributing to surgical research to be able to do so. Social media has led to a paradigm shift in how surgical research may be conducted. Diversity of thought in research is improving, and engagement in surgical research is at an all-time high. Collaboration of all stakeholders is key to #SoMe4Surgery success and is the new 'gold standard' of surgical research.

PANC Study (Pancreatitis: A National Cohort Study): national cohort study examining the first 30 days from presentation of acute pancreatitis in the UK. BJS Open 2023; 7:zrad008. [PMID: 37161673 PMCID: PMC10170253 DOI: 10.1093/bjsopen/zrad008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 12/01/2022] [Accepted: 01/04/2023] [Indexed: 05/11/2023] Open
Abstract
BACKGROUND Acute pancreatitis is a common, yet complex, emergency surgical presentation. Multiple guidelines exist and management can vary significantly. The aim of this first UK, multicentre, prospective cohort study was to assess the variation in management of acute pancreatitis to guide resource planning and optimize treatment. METHODS All patients aged greater than or equal to 18 years presenting with acute pancreatitis, as per the Atlanta criteria, from March to April 2021 were eligible for inclusion and followed up for 30 days. Anonymized data were uploaded to a secure electronic database in line with local governance approvals. RESULTS A total of 113 hospitals contributed data on 2580 patients, with an equal sex distribution and a mean age of 57 years. The aetiology was gallstones in 50.6 per cent, with idiopathic the next most common (22.4 per cent). In addition to the 7.6 per cent with a diagnosis of chronic pancreatitis, 20.1 per cent of patients had a previous episode of acute pancreatitis. One in 20 patients were classed as having severe pancreatitis, as per the Atlanta criteria. The overall mortality rate was 2.3 per cent at 30 days, but rose to one in three in the severe group. Predictors of death included male sex, increased age, and frailty; previous acute pancreatitis and gallstones as aetiologies were protective. Smoking status and body mass index did not affect death. CONCLUSION Most patients presenting with acute pancreatitis have a mild, self-limiting disease. Rates of patients with idiopathic pancreatitis are high. Recurrent attacks of pancreatitis are common, but are likely to have reduced risk of death on subsequent admissions.

The ChoCO-W prospective observational global study: Does COVID-19 increase gangrenous cholecystitis? World J Emerg Surg 2022; 17:61. [PMID: 36527038 PMCID: PMC9755784 DOI: 10.1186/s13017-022-00466-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Accepted: 10/15/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. METHODS Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. RESULTS A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p < 0.0001), diabetes (p < 0.0001), and severe chronic obstructive airway disease (p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p < 0.0001), PIPAS score (p < 0.0001), WSES sepsis score (p < 0.0001), qSOFA (p < 0.0001), and Tokyo classification of severity of acute cholecystitis (p < 0.0001) were significantly higher in the COVID-19 group. The COVID-19 group had significantly higher postoperative complications (32.2% compared with 11.7%, p < 0.0001), longer mean hospital stay (13.21 compared with 6.51 days, p < 0.0001), and mortality rate (13.4% compared with 1.7%, p < 0.0001). The incidence of gangrenous cholecystitis was doubled in the COVID-19 group (40.7% compared with 22.3%). The mean wall thickness of the gallbladder was significantly higher in the COVID-19 group [6.32 (SD: 2.44) mm compared with 5.4 (SD: 3.45) mm; p < 0.0001]. CONCLUSIONS The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands.

Exploring variation in surgical practice: does surgeon personality influence anastomotic decision-making? Br J Surg 2022; 109:1156-1163.

Abstract
BACKGROUND Decision-making under uncertainty may be influenced by an individual's personality. The primary aim was to explore associations between surgeon personality traits and colorectal anastomotic decision-making. METHODS Colorectal surgeons worldwide participated in a two-part online survey. Part 1 evaluated surgeon characteristics using the Big Five Inventory to measure personality (five domains: agreeableness; conscientiousness; extraversion; emotional stability; openness) in response to scenarios presented in Part 2 involving anastomotic decisions (i.e. rejoining the bowel with/without temporary stomas, or permanent diversion with end colostomy). Anastomotic decisions were compared using repeated-measure ANOVA. Mean scores of traits domains were compared with normative data using two-tailed t tests. RESULTS In total, 186 surgeons participated, with 127 surgeons completing both parts of the survey (68.3 per cent). One hundred and thirty-one surgeons were male (70.4 per cent) and 144 were based in Europe (77.4 per cent). Forty-one per cent (77 surgeons) had begun independent practice within the last 5 years. Surgeon personality differed from the general population, with statistically significantly higher levels of emotional stability (3.25 versus 2.97 respectively), lower levels of agreeableness (3.03 versus 3.74), extraversion (2.81 versus 3.38) and openness (3.19 versus 3.67), and similar levels of conscientiousness (3.42 versus 3.40 (all P <0.001)). Female surgeons had significantly lower levels of openness (P <0.001) than males (3.06 versus 3.25). Personality was associated with anastomotic decision-making in specific scenarios. CONCLUSION Colorectal surgeons have different personality traits from the general population. Certain traits seem to be associated with anastomotic decision-making but only in specific scenarios. Further exploration of the association of personality, risk-taking, and decision-making in surgery is necessary.

WE5.10 Death in the early post-operative period: recognising the concept of non-beneficiality in emergency laparotomy and modelling its predictors. Br J Surg 2022.

Abstract
Abstract
Background
The publication of data from the National Emergency Laparotomy Audit (NELA) has resulted in overall improvement in post-operative mortality rates. However, little is known about the characteristics of patients that die in the immediate post-operative period. These patients may represent a missed opportunity for the consideration of palliation. We describe this specific group of patients where death occurred within three days of emergency laparotomy, and investigate predictors of early mortality.
Methods
All patients enrolled in the NELA database from December 2013–2020 were included. Early post-operative death was defined as all-cause mortality within three days of emergency laparotomy. Multi-level logistic regression was carried out with potentially clinically important predictors defined a priori. Frailty was modelled separately due to missing data.
Results
Four per cent of patients (7,442/180,987) died in the early post-operative period and 85% were admitted to critical care post-operatively. Median NELA risk score was 32.4% compared to 3.8% in the rest of the cohort (p<0.001). One in four patients were commenced on an end-of-life pathway following laparotomy. Significant predictors on multivariate analysis included female sex, increasing age, higher ASA, surgery for intestinal ischaemia or perforation, hypotension, reduced GCS, urgency of surgery, cardiac and respiratory signs (n=178,442). The addition of frailty (n=52,766) was also predictive (OR 1.37; 95% CI 1.22–1.55) when added to the model.
Conclusion
Early post-operative mortality is associated with quantifiable predictable factors in addition to the NELA risk score. This finding has significant implications for the multi-disciplinary team having shared decision-making discussions with extremely high-risk patients.

Modelling of magnetic microbubbles to evaluate contrast enhanced magnetomotive ultrasound in lymph nodes - a pre-clinical study. Br J Radiol 2022; 95:20211128.

Abstract
OBJECTIVES Despite advances in MRI the detection and characterisation of lymph nodes in rectal cancer remains complex, especially when assessing the response to neoadjuvant treatment. An alternative approach is functional imaging, previously shown to aid characterisation of cancer tissues. We report proof of concept of the novel technique Contrast-Enhanced Magneto-Motive Ultrasound (CE-MMUS) to recover information relating to local perfusion and lymphatic drainage, and interrogate tissue mechanical properties through magnetically induced deformations. METHODS The feasibility of the proposed application was explored using a combination of experimental animal and phantom ultrasound imaging, along with finite element analysis. First, contrast-enhanced ultrasound imaging on one wild type mouse recorded lymphatic drainage of magnetic microbubbles after bolus injection. Second, tissue phantoms were imaged using MMUS to illustrate the force- and elasticity dependence of the magnetomotion. Third, the magnetomechanical interactions of a magnetic microbubble with an elastic solid were simulated using finite element software. RESULTS Accumulation of magnetic microbubbles in the inguinal lymph node was verified using contrast enhanced ultrasound, with peak enhancement occurring 3.7 s post-injection. The magnetic microbubble gave rise to displacements depending on force, elasticity, and bubble radius, indicating an inverse relation between displacement and the latter two. CONCLUSION Combining magnetic microbubbles with MMUS could harness the advantages of both techniques, to provide perfusion information, robust lymph node delineation and characterisation based on mechanical properties. ADVANCES IN KNOWLEDGE (a) Lymphatic drainage of magnetic microbubbles visualised using contrast-enhanced ultrasound imaging and (b) magnetomechanical interactions between such bubbles and surrounding tissue could both contribute to (c) robust detection and characterisation of lymph nodes.

Abstract
AIM There is evolving evidence that preoperative frailty predicts outcomes of older adults undergoing emergency laparotomy (EmLap). We assessed frailty scoring in an emergency surgical population that included patients of all ages and then compared this to an established perioperative prognostic score. METHOD Data from the prospective Emergency Laparoscopic and Laparotomy Scottish Audit (ELLSA; November 2017-October 2018) was used. All adults over 18 were included. Frailty was measured using 7-point clinical frailty score (CFS). OUTCOME MEASURES 30-day mortality, hospital length of stay (LOS), 30-day readmission. Areas under the receiver-operating characteristic (ROC) curves were calculated for CFS (1-7) and compared to the National Emergency Laparotomy Audit (NELA) score with Forest plots used to compare 30-day mortality across CFS and NELA categories. RESULTS A total of 2246 patients (median age 65 years [IQR 51-75]; female 51%) underwent EmLap (60% for colorectal pathology). A total of 10.6% were frail preoperatively (≥CFS 5). As CFS increased so did 30-day mortality (2.1% CFS1 to 25.3% CFS6 and 7; ꭓ2 78.2, p < 0.001) and median LOS (10 days CFS1 to 20 days CFS6 and 7; p < 0.001). Readmission rates did not differ significantly across CFS. ROC (95% CI) for mortality was 0.71 (0.65-0.77) for CFS and 0.84 (0.78-0.89) for NELA. Addition of CFS to NELA did not increase ROC value. CONCLUSION This study supports the prognostic role of frailty in the emergency surgical setting, finding increasing frailty to be associated with increased mortality and longer LOS in adults of all ages. Although NELA performed better, CFS remained predictive and has the advantage of being calculated preoperatively to aid decision-making and treatment planning.

Abstract
BACKGROUND Futile is defined as 'the fact of having no effect or of achieving nothing'. Futility in medicine has been defined through seven guiding principles, which in the context of emergency surgery, have been relatively unexplored. This scoping review aimed to identify key concepts around surgical futility as it relates to emergency laparotomy. METHODS Using the Arksey and O'Malley framework, a scoping review was conducted. A search of the Cochrane Library, Google Scholar, MEDLINE, and Embase was performed up until 1 November 2021 to identify literature relevant to the topic of futility in emergency laparotomy. RESULTS Three cohort studies were included in the analysis. A total of 105 157 patients were included, with 1114 patients reported as futile. All studies were recent (2019 to 2020) and focused on the principle of quantitative futility (assessment of the probability of death after surgery) within a timeline after surgery: two defining futility as death within 48 hours of surgery and one as death within 72 hours. In all cases this was derived from a survival histogram. Predictors of defined futile procedures included age, level of independence prior to admission, surgical pathology, serum creatinine, arterial lactate, and pH. CONCLUSION There remains a paucity of research defining, exploring, and analysing futile surgery in patients undergoing emergency laparotomy. With limited published work focusing on quantitative futility and the binary outcome of death, research is urgently needed to explore all principles of futility, including the wishes of patients and their families.

Prehabilitation services for people diagnosed with cancer in Scotland - Current practice, barriers and challenges to implementation. Surgeon 2021; 20:284-290. [PMID: 34535399 DOI: 10.1016/j.surge.2021.08.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 08/09/2021] [Accepted: 08/19/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Prehabilitation is the practice of enhancing a patient's functional and psychological capacity before treatment commences. It is of interest in the cancer context because of the impact of treatments on quality of life and cancer survivorship. This work aims to document current practice, barriers and challenges to implementing prehabilitation to inform the development of a national framework. METHODS A mixed-methods approach was applied: an on-line survey was sent to stakeholders in cancer care across Scotland, supplemented by in-depth interviews. Key domains explored were the perceived importance of prehabilitation, availability, delivery and content of services, outcome measures, referral processes and funding. FINDINGS A total of 295 survey responses were obtained and 11 interviews completed. Perceived importance of prehabilitation was rated highly. There was uncertainty over the definition of prehabilitation and most respondents did not know if local services were available. Where services were described, a range of health professionals were involved, different outcome measures were utilised and frequency of referrals varied. Respondents highlighted short time frames between referral and treatment, concerns about patient engagement, the evidence base for action and funding priorities. Respondents also commented on which context a referral should be made and to whom, and the need for equity of service across the country. CONCLUSIONS The current work found clear evidence of the perceived importance of prehabilitation in cancer patients. However, issues and key gaps were identified within current services (including issues arising from COVID-19) which must be addressed to enable wide-spread development and implementation of equitable programmes.

Decision making in emergency laparotomy: the role of predicted life expectancy. BJS Open 2021; 5:6388194. [PMID: 34633437 PMCID: PMC8504444 DOI: 10.1093/bjsopen/zrab090] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 08/16/2021] [Indexed: 11/14/2022] Open
Abstract
Introduction Increasing numbers of older patients are undergoing emergency laparotomy (EL). They are at increased risk of adverse outcomes, making the shared decision on whether to operate challenging. This retrospective cohort study aimed to assess the role of age and life-expectancy predictions on short- and long-term survival in patients undergoing EL. Methods All patients who underwent EL at one hospital in the West of Scotland between March 2014 to December 2016 were included. Clinical parameters were collected, and patients were followed up to allow reporting of 30-, 60- and 90-day and 1-year mortality rates. Period life expectancy was used to stratify patients into below life expectancy (bLEP) and at-or-above life expectancy (aLEP) groups at presentation. Remaining life expectancy was used to calculate the net years of life gained (NYLG). Results Some 462 patients underwent EL: 20 per cent in the aLEP group. These patients were older (P < 0.001), had more co-morbidities (P < 0.001) and were high risk on P-POSSUM scoring (P = 0.008). The 30-, 60- and 90-day and 1-year mortality rates were 11, 14, 16 and 23 per cent respectively. Advanced age (P = 0.011) and high ASA score (P = 0.004) and P-POSSUM score (P < 0.001) were independent predictors of death at 1 year on multivariable analysis. The cohort NYLG were 19.2 years. Comparing patients aged less than 70 with those aged 70 years or older, the NYLG were 25.9 versus 5.5 years. Comparing bLEP and aLEP, the NYLG were 22.2 versus 4.4 years. In patients aged 70 years and older, NYLG decreased by more than half in patients with co-morbidities (ASA score 3,4,5) (9.3 versus 4.3 years). Conclusion Discussions around long-term outcomes after emergency surgery remain difficult. Although age is an influencing factor, predicted life expectancy alone does not provide additional value to shared decision making.

Antibiotics as first-line alternative to appendicectomy in adult appendicitis: 90-day follow-up from a prospective, multicentre cohort study. Br J Surg 2021; 108:1351-1359. [PMID: 34476484 PMCID: PMC8499866 DOI: 10.1093/bjs/znab287] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 07/20/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Uncomplicated acute appendicitis can be managed with non-operative (antibiotic) treatment, but laparoscopic appendicectomy remains the first-line management in the UK. During the COVID-19 pandemic the practice altered, with more patients offered antibiotics as treatment. A large-scale observational study was designed comparing operative and non-operative management of appendicitis. The aim of this study was to evaluate 90-day follow-up. METHODS A prospective, cohort study at 97 sites in the UK and Republic of Ireland included adult patients with a clinical or radiological diagnosis of appendicitis that either had surgery or non-operative management. Propensity score matching was conducted using age, sex, BMI, frailty, co-morbidity, Adult Appendicitis Score and C-reactive protein. Outcomes were 90-day treatment failure in the non-operative group, and in the matched groups 30-day complications, length of hospital stay (LOS) and total healthcare costs associated with each treatment. RESULTS A total of 3420 patients were recorded: 1402 (41 per cent) had initial antibiotic management and 2018 (59 per cent) had appendicectomy. At 90-day follow-up, antibiotics were successful in 80 per cent (1116) of cases. After propensity score matching (2444 patients), fewer overall complications (OR 0.36 (95 per cent c.i. 0.26 to 0.50)) and a shorter median LOS (2.5 versus 3 days, P < 0.001) were noted in the antibiotic management group. Accounting for interval appendicectomy rates, the mean total cost was €1034 lower per patient managed without surgery. CONCLUSION This study found that antibiotics is an alternative first-line treatment for adult acute appendicitis and can lead to cost reductions.

Healthcare professional preferences in the health and fitness assessment and optimization of older patients facing colorectal cancer surgery. Colorectal Dis 2021; 23:2331-2340. [PMID: 34046988 DOI: 10.1111/codi.15758] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 04/26/2021] [Accepted: 05/18/2021] [Indexed: 12/14/2022]
Abstract
AIM There are few age- and fitness-specific, evidence-based guidelines for colorectal cancer surgery. The uptake of different assessment and optimization strategies is variable. The aim of this study was to explore healthcare professional opinion about these issues using a mixed methods design. METHODS Semi-structured qualitative interviews were undertaken with healthcare professionals from a single UK region involved in the treatment, assessment and optimization of colorectal surgery patients. Interviews were analysed using the framework approach. An online questionnaire survey was subsequently designed and disseminated to UK surgeons to quantitatively assess the importance of interview themes. Descriptive statistics were used to analyse questionnaire data. RESULTS Thirty-seven healthcare professionals out of 42 approached (response rate 88%) were interviewed across five hospitals in the south Yorkshire region. Three broad themes were developed: attitudes towards treatment of the older patient, methods of assessment of suitability and optimization strategies. The questionnaire was completed by 103 out of an estimated 256 surgeons (estimated response rate 40.2%). There was a difference in opinion regarding the role of major surgery in older patients, particularly when there is coexisting dementia. Assessment was not standardized. Access to optimization strategies was limited, particularly in the emergency setting. CONCLUSION There is wide variation in the process of assessment and provision of optimization strategies in UK practice. Lack of evidence-based guidelines, cost and time constraints restrict the development of services and pathways. Differences in opinion between surgeons towards patients with frailty or dementia may account for some of the variation in colorectal cancer outcomes.

Frailty in Older Patients Undergoing Emergency Laparotomy: Results From the UK Observational Emergency Laparotomy and Frailty (ELF) Study. Ann Surg 2021; 273:709-718. [PMID: 31188201 DOI: 10.1097/sla.0000000000003402] [Citation(s) in RCA: 114] [Impact Index Per Article: 38.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
OBJECTIVE This study aimed to document the prevalence of frailty in older adults undergoing emergency laparotomy and to explore relationships between frailty and postoperative morbidity and mortality. SUMMARY BACKGROUND DATA The majority of adults undergoing emergency laparotomy are older adults (≥65 y) that carry the highest mortality. Improved understanding is urgently needed to allow development of targeted interventions. METHODS An observational multicenter (n=49) UK study was performed (March-June 2017). All older adults undergoing emergency laparotomy were included. Preoperative frailty score was calculated using the progressive Clinical Frailty Score (CFS): 1 (very fit) to 7 (severely frail). Primary outcome measures were the prevalence of frailty (CFS 5-7) and its association to mortality at 90 days postoperative. Secondary outcomes included 30-day mortality and morbidity, length of critical care, and overall hospital stay. RESULTS A total of 937 older adults underwent emergency laparotomy: frailty was present in 20%. Ninety-day mortality was 19.5%. After age and sex adjustment, the risk of 90-day mortality was directly associated with frailty: CFS 5 adjusted odds ratio (aOR) 3.18 [95% confidence interval (CI), 1.24-8.14] and CFS 6/7 aOR 6·10 (95% CI, 2.26-16.45) compared with CFS 1. Similar associations were found for 30-day mortality. Increasing frailty was also associated with increased risk of complications, length of Intensive Care Unit, and overall hospital stay. CONCLUSIONS A fifth of older adults undergoing emergency laparotomy are frail. The presence of frailty is associated with greater risks of postoperative mortality and morbidity and is independent of age. Frailty scoring should be integrated into acute surgical assessment practice to aid decision-making and development of novel postoperative strategies.

Increased care at discharge from COVID-19: The association between pre-admission frailty and increased care needs after hospital discharge; a multicentre European observational cohort study. BMC Med 2020; 18:408. [PMID: 33334341 PMCID: PMC7746415 DOI: 10.1186/s12916-020-01856-8] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Accepted: 11/17/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic has placed significant pressure on health and social care. Survivors of COVID-19 may be left with substantial functional deficits requiring ongoing care. We aimed to determine whether pre-admission frailty was associated with increased care needs at discharge for patients admitted to hospital with COVID-19. METHODS Patients were included if aged over 18 years old and admitted to hospital with COVID-19 between 27 February and 10 June 2020. The Clinical Frailty Scale (CFS) was used to assess pre-admission frailty status. Admission and discharge care levels were recorded. Data were analysed using a mixed-effects logistic regression adjusted for age, sex, smoking status, comorbidities, and admission CRP as a marker of severity of disease. RESULTS Thirteen hospitals included patients: 1671 patients were screened, and 840 were excluded including, 521 patients who died before discharge (31.1%). Of the 831 patients who were discharged, the median age was 71 years (IQR, 58-81 years) and 369 (44.4%) were women. The median length of hospital stay was 12 days (IQR 6-24). Using the CFS, 438 (47.0%) were living with frailty (≥ CFS 5), and 193 (23.2%) required an increase in the level of care provided. Multivariable analysis showed that frailty was associated with an increase in care needs compared to patients without frailty (CFS 1-3). The adjusted odds ratios (aOR) were as follows: CFS 4, 1.99 (0.97-4.11); CFS 5, 3.77 (1.94-7.32); CFS 6, 4.04 (2.09-7.82); CFS 7, 2.16 (1.12-4.20); and CFS 8, 3.19 (1.06-9.56). CONCLUSIONS Around a quarter of patients admitted with COVID-19 had increased care needs at discharge. Pre-admission frailty was strongly associated with the need for an increased level of care at discharge. Our results have implications for service planning and public health policy as well as a person's functional outcome, suggesting that frailty screening should be utilised for predictive modelling and early individualised discharge planning.

Exploring shared surgical decision-making from the patient's perspective: is the personality of the surgeon important? Colorectal Dis 2020; 22:2214-2221. [PMID: 32628311 DOI: 10.1111/codi.15237] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Accepted: 06/16/2020] [Indexed: 02/08/2023]
Abstract
AIM The aim was to determine the importance of a colorectal surgeon's personality to patients and its influence on their decision-making. METHODS We present a two-part mixed methods study using the Guidance for Reporting Involvement of Patients and the Public (GRIPP-2) long form. Part 1 was an online survey (25 questions) and Part 2 a face-to-face patient and public involvement exercise. Part 1 included patient demographics, details of surgery, overall patient satisfaction (net promoter score) and patient views on surgeon personality (Gosling 10 Item Personality Index). The thematic analysis of free-text responses generated four themes that were taken forward to Part 2. These themes were used to structure focus group discussions on surgeon-patient interactions. RESULTS Part 1 yielded 296 responses: 72% women, 75.3% UK-based and 55.1% aged 40-59 years. Inflammatory bowel disease (45.3%) and cancer (40.2%) were the main indications. 84.1% of respondents reported satisfaction with their surgical experience (net promoter score). Four key themes were generated from Part 1 and validated in Part 2: (i) surgeon personality stereotypes (media differed from patients' perspective); (ii) favourable and unfavourable surgical personality traits (openness, conscientiousness, emotional stability preferred over risk-taking and narcissism); (iii) patient-surgeon interaction (mutual respect and rapport valued); (iv) impact of surgeon personality on decision-making (majority unaware of second opinion option; management of postoperative complications). CONCLUSION Patients believe surgeon personality influences shared decision-making. Low levels of emotional stability and conscientiousness are perceived by patients to increase the likelihood of postoperative adverse events. Further work is required to explore the potential influence of surgeon personality on shared decision-making and postoperative outcomes.

Decision-making for older patients undergoing emergency laparotomy: defining patient and clinician values and priorities. Colorectal Dis 2020; 22:1694-1703.

Abstract
AIM There remains limited knowledge on what patients value and prioritize in their decision to undergo emergency laparotomy (ELap) and during their subsequent recovery. The aim of this study was to explore factors in decision-making and to reach a consensus amongst patients on the 10 most important priorities in decision-making in ELap. METHODS Patients aged over 65 years who had required an ELap decision within the preceding 12 months (regardless of management) were identified and invited to attend a modified Delphi process focus group. RESULTS A total of 20 participants attended: eight patients, four relatives and eight perioperative specialists. The perioperative specialists group defined 12 important factors for perioperative decision-making. The patient group agreed that only six (50%) of these factors were important: independence, postoperative complications, readmission to hospital, requirement for stoma formation, delirium (including long-term cognition) and presence of an advocate (such as a friend or family member). Open discussion refined multiple themes. Agreement was reached by patients and relatives about 10 factors that they valued as most important in their ELap patient journey: return to independence, realistic expectations, postoperative complications, what to expect postoperatively, readmission to hospital, nutrition, postoperative communication, stoma, follow-up and delirium. CONCLUSION Patients and clinicians have different values and priorities when discussing the risks and implications of undergoing ELap. Patients value quality of life outcomes, in particular, the formation of a stoma, returning to their own home and remaining independent. This work is the first to combine both perspectives to guide future ELap research outcomes.

Abstract
Abstract
Background
Frailty is associated with advancing age and may result in adverse postoperative outcomes. A suspected growing elderly population needing emergency colorectal surgery stimulated this study of the prevalence and impact of frailty.
Methods
Elderly patients (defined as aged at least 65 years by Medicare and the United States Census Bureau) who underwent emergency colorectal resection between 2012 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program population database. The five-item modified frailty index (mFI-5) score was calculated, and patients stratified into groups 0, 1 or 2 +. Main outcome measures were the prevalence of frailty, and its impact on 30-day postoperative morbidity, mortality, reoperation, duration of hospital stay (LOS), discharge destination and readmission.
Results
A total of 10 025 patients were identified with a median age 75 years, of whom 41·8 per cent were men. The majority (87·7 per cent) had an ASA fitness grade of III or greater and 3129 (31·2 per cent) were frail (mFI-5 group 2+). Major morbidity occurred in one-third of patients and the postoperative mortality rate was 15·9 per cent. Some 52·0 per cent of patients had a prolonged hospital stay and 11·0 per cent were readmitted. Although most patients (88·0 per cent) lived independently before surgery, only 45·4 per cent were discharged home directly. Frailty (mFI-5 2+) predicted mortality, overall and major morbidity, reoperation, prolonged LOS, discharge to an institution and readmission, but frailty was independent of sex.
Conclusion
Frailty is associated with morbidity, mortality and loss of independence in elderly patients needing emergency colorectal surgery.

Abstract
Background The COVID-19 pandemic has placed unprecedented strain on health-care systems. Frailty is being used in clinical decision making for patients with COVID-19, yet the prevalence and effect of frailty in people with COVID-19 is not known. In the COVID-19 in Older PEople (COPE) study we aimed to establish the prevalence of frailty in patients with COVID-19 who were admitted to hospital and investigate its association with mortality and duration of hospital stay. Methods This was an observational cohort study conducted at ten hospitals in the UK and one in Italy. All adults (≥18 years) admitted to participating hospitals with COVID-19 were included. Patients with incomplete hospital records were excluded. The study analysed routinely generated hospital data for patients with COVID-19. Frailty was assessed by specialist COVID-19 teams using the clinical frailty scale (CFS) and patients were grouped according to their score (1–2=fit; 3–4=vulnerable, but not frail; 5–6=initial signs of frailty but with some degree of independence; and 7–9=severe or very severe frailty). The primary outcome was in-hospital mortality (time from hospital admission to mortality and day-7 mortality). Findings Between Feb 27, and April 28, 2020, we enrolled 1564 patients with COVID-19. The median age was 74 years (IQR 61–83); 903 (57·7%) were men and 661 (42·3%) were women; 425 (27·2%) had died at data cutoff (April 28, 2020). 772 (49·4%) were classed as frail (CFS 5–8) and 27 (1·7%) were classed as terminally ill (CFS 9). Compared with CFS 1–2, the adjusted hazard ratios for time from hospital admission to death were 1·55 (95% CI 1·00–2·41) for CFS 3–4, 1·83 (1·15–2·91) for CFS 5–6, and 2·39 (1·50–3·81) for CFS 7–9, and adjusted odds ratios for day-7 mortality were 1·22 (95% CI 0·63–2·38) for CFS 3–4, 1·62 (0·81–3·26) for CFS 5–6, and 3·12 (1·56–6·24) for CFS 7–9. Interpretation In a large population of patients admitted to hospital with COVID-19, disease outcomes were better predicted by frailty than either age or comorbidity. Our results support the use of CFS to inform decision making about medical care in adult patients admitted to hospital with COVID-19. Funding None.

Abstract
Background Vibrational spectroscopy (VS) is a minimally invasive tool for analysing biological material to detect disease. This study aimed to review its application to human blood for cancer diagnosis. Methods A systematic review was undertaken using a keyword electronic database search (MEDLINE, Embase, PubMed, TRIP and Cochrane Library), with all original English‐language manuscripts examining the use of vibrational spectral analysis of human blood for cancer detection. Studies involving fewer than 75 patients in the cancer or control group, animal studies, or where the primary analyte was not blood were excluded. Results From 1446 results, six studies (published in 2010–2018) examining brain, bladder, oral, breast, oesophageal and hepatic cancer met the criteria for inclusion, with a total population of 2392 (1316 cancer, 1076 control; 1476 men, 916 women). For cancer detection, reported mean sensitivities in each included study ranged from 79·3 to 98 per cent, with specificities of 82·8–95 per cent and accuracies between 81·1 and 97·1 per cent. Heterogeneity in reporting strategies, methods and outcome measures made meta‐analysis inappropriate. Conclusion VS shows high potential for cancer diagnosis, but until there is agreement on uniform standard reporting methods and studies with adequate sample size for valid classification models have been performed, its value in clinical practice will remain uncertain.

Abstract
Abstract
Background
Older adults undergoing emergency abdominal surgery have significantly poorer outcomes than younger adults. For those who survive, the level of care required on discharge from hospital is unknown and such information could guide decision-making. The ELF (Emergency Laparotomy and Frailty) study aimed to determine whether preoperative frailty in older adults was associated with increased dependence at the time of discharge.
Methods
The ELF study was a UK-wide multicentre prospective cohort study of older patients (65 years or more) undergoing emergency laparotomy during March and June 2017. The objective was to establish whether preoperative frailty was associated with increased care level at discharge compared with preoperative care level. The analysis used a multilevel logistic regression adjusted for preadmission frailty, patient age, sex and care level.
Results
A total of 934 patients were included from 49 hospitals. Mean(s.d.) age was 76·2(6·8) years, with 57·6 per cent women; 20·2 per cent were frail. Some 37·4 per cent of older adults had an increased care level at discharge. Increasing frailty was associated with increased discharge care level, with greater predictive power than age. The adjusted odds ratio for an increase in care level was 4·48 (95 per cent c.i. 2·03 to 9·91) for apparently vulnerable patients (Clinical Frailty Score (CFS) 4), 5·94 (2·54 to 13·90) for those mildly frail (CFS 5) and 7·88 (2·97 to 20·79) for those moderately or severely frail (CFS 6 or 7), compared with patients who were fit.
Conclusion
Over 37 per cent of older adults undergoing emergency laparotomy required increased care at discharge. Frailty scoring was a significant predictor, and should be integrated into all acute surgical units to aid shared decision-making and discharge planning.

The relationship between sarcopenia and survival at 1 year in patients having elective colorectal cancer surgery. Tech Coloproctol 2019; 23:877-885. [PMID: 31486988 PMCID: PMC6791904 DOI: 10.1007/s10151-019-02072-0] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Accepted: 08/20/2019] [Indexed: 12/12/2022]
Abstract
Background Colorectal cancer remains a common cause of cancer death in the UK, with surgery being the mainstay of treatment. An objective measurement of the suitability of each patient for surgery, and their risk–benefit calculation, would be of great utility. We postulate that sarcopenia (low muscle mass) could fulfil this role as a prognostic indicator. The aim of this study was to determine the relationship between sarcopenia and long-term outcomes in patients undergoing elective bowel resection for colorectal cancer. Methods One hundred and sixty-three consecutive patients who had elective curative colorectal resection for cancer were eligible for inclusion in the study. Psoas muscle mass was assessed on preoperative computed tomography scan at the level of the L3 vertebra and standardised for patient height (total psoas index, TPI). Sarcopenia (low muscle mass) was defined as < 524 mm2/m2 in males and 385 mm2/m2 in females. In addition to clinical–pathological parameters, postoperative complications were recorded and patients were followed up for mortality for 1 year after surgery. Results Sarcopenia was present in 19.6% of the study participants and was significantly related to body mass index (p = 0.007), 30-day mortality (p = 0.042) and 1-year mortality (p = 0.046). In univariate analysis, American Society of Anesthesiologists grade (p = 0.016), tumour stage (p = 0.018) and sarcopenia (p = 0.043) were found to be significant independent predictors of 1-year mortality. Conclusions This study has found sarcopenia to be prevalent in patients with colorectal cancer having elective surgery. Independent of age, sarcopenia was associated with poorer 30-day mortality and survival at 1 year. Measurement of muscle mass preoperatively could be used to stratify a patient’s risk, allowing targeted strategies such as prehabilitation, to be implemented to modify sarcopenia and improve long-term outcomes for patients.

Barriers and facilitators to deliberate practice using take-home laparoscopic simulators. Surg Endosc 2019; 33:2951-2959. [PMID: 30456507 PMCID: PMC6684499 DOI: 10.1007/s00464-018-6599-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Accepted: 11/13/2018] [Indexed: 11/26/2022]
Abstract
BACKGROUND Several regions in the UK and Ireland have delivered home-based laparoscopic simulation programmes in an attempt to progress surgical trainees' skills through deliberate practice. However, engagement with these programmes has been poor. This study aims to uncover the barriers to engagement with home-based simulation, with a view to developing an improved programme. METHODS This was a qualitative study using focus groups with key stakeholders including junior surgical trainees, consultants/attendings and simulation faculty. Data were collected across four regions in three countries. Data were audio-recorded, transcribed and a thematic analysis was performed using NVivo software. RESULTS Sixty-three individuals were interviewed in 12 focus groups (43 trainees, 20 trainers). Trainees cited competing commitments as a barrier to engaging with home-based simulation. They tended to focus on scoring 'points' towards career progression rather than viewing tasks as interesting, or associated with personal development. Their view was that this approach is perpetuated by the training system, which rewards trainees for publications and exams, but not for operative skill. Trainees were unsatisfied with metric feedback and wanted individual feedback from consultants (attendings). Trainees perceived consultants as lacking interest in the programmes and training in general. However, some consultants were unaware of the programmes being delivered and others felt lacking in confidence to deliver the necessary training. CONCLUSIONS Scheduled simulation sessions which provide trainees with the opportunity for consultant feedback may improve engagement. Tackling the 'point-scoring' culture is more challenging. This could be addressed by modified assessment structures, greater recognition and accountability for trainers, and recognition and funding of simulation strategies including in-house skills sessions.

Prehabilitation is feasible in patients with rectal cancer undergoing neoadjuvant chemoradiotherapy and may minimize physical deterioration: results from the REx trial. Colorectal Dis 2019; 21:548-562.

Abstract
AIM Rectal cancer patients undergoing neoadjuvant chemoradiotherapy (NACRT) experience physical deterioration and reductions in their quality of life. This feasibility study assessed prehabilitation (a walking intervention) before, during and after NACRT to inform a definitive multi-centred randomized clinical trial (REx trial). METHODS Patients planned for NACRT followed by potentially curative surgery were approached (August 2014-March 2016) (www.isrctn.com; 62859294). Prior to NACRT, baseline physical and psycho-social data were recorded using validated tools. Participants were randomized to either the intervention group (exercise counselling session followed by a 13-17 week telephone-guided walking programme) or a control group (standard care). Follow-up testing was undertaken 1-2 weeks before surgery. RESULTS Of the 296 screened patients, 78 (26%) were eligible and 48 (61%) were recruited. N = 31 (65%) were men with a mean age of 65.9 years (range 33.7-82.6). Mean intervention duration was 14 weeks with 75% adherence. n = 40 (83%) completed follow-up testing. Both groups recorded reductions in daily walking but the reduction was less in the intervention group although not statistically significant. Participants reported high satisfaction and fidelity to trial procedures. CONCLUSION This study demonstrates that prehabilitation is feasible in rectal cancer patients undergoing NACRT. Good recruitment, adherence, retention and patient satisfaction rates support the development of a fully powered trial. The effects of the intervention on physical outcomes were promising.

Frailty predicts mortality in all emergency surgical admissions regardless of age. An observational study. Age Ageing 2019; 48:388-394.

Abstract
BACKGROUND frail patients in any age group are more likely to die than those that are not frail. We aimed to evaluate the impact of frailty on clinical mortality, readmission rate and length of stay for emergency surgical patients of all ages. METHODS a multi-centre prospective cohort study was conducted on adult admissions to acute surgical units. Every patient presenting as a surgical emergency to secondary care, regardless of whether they ultimately underwent a surgical procedure was included. The study was carried out during 2015 and 2016.Frailty was defined using the 7-point Clinical Frailty Scale. The primary outcome was mortality at Day 90. Secondary outcomes included: mortality at Day 30, length of stay and readmission within a Day 30 period. RESULTS the cohort included 2,279 patients (median age 54 years [IQR 36-72]; 56% female). Frailty was documented in patients of all ages: 1% in the under 40's to 45% of those aged 80+. We found that each incremental step of worsening frailty was associated with an 80% increase in mortality at Day 90 (OR 1.80, 95% CI: 1.61-2.01) supporting a linear dose-response relationship. In addition, the most frail patients were increasingly likely to stay in hospital longer, be readmitted within 30 days, and die within 30 days. CONCLUSIONS worsening frailty at any age is associated with significantly poorer patient outcomes, including mortality in unselected acute surgical admissions. Assessment of frailty should be integrated into emergency surgical practice to allow prognostication and implementation of strategies to improve outcomes.

Abstract
AIM Enhanced recovery after surgery (ERAS) programmes aim to standardise perioperative care leading to optimal patient outcomes. Despite these programmes, variation in outcomes still persists. This study aimed to assess the influence of lifestyle factors on short-term outcomes after colorectal surgery within this optimal recovery programme. METHODS Consecutive patients enrolled on an ERAS pathway who underwent elective colorectal surgery (June 2013 to July 2014) at one site were included. We used data routinely collected by ERAS nurse specialists and during preassessment to analyse association between patient and lifestyle factors and likelihood of developing postoperative complications or having an increased length of stay. RESULTS A total of 199 patients were included: mean age 61.8 years (range 17-90 years) and 53.8% male. Age, sex, deprivation, smoking status, alcohol intake, body mass index or level of comorbidity were not associated with postoperative complications. Patients reporting limited preoperative physical capacity (unable to climb two flights of stairs) were more than four times as likely to have a postoperative complication on univariate analysis and were found to still have increased risk of postoperative complications on multivariate analysis. Patients reporting limited preoperative physical capacity were shown to have significantly longer hospital stay on univariate analysis. In the multivariate analysis, limited physical capacity was not associated with prolonged length of stay due to confounding factors of age and deprivation. CONCLUSIONS Limited physical capacity was the only patient and lifestyle factor associated with poorer postoperative complications and prolonged hospital stay after elective colorectal surgery within an ERAS programme. Consideration should be given to individualised prehabilitation that aims to increase physical capacity pre-operatively to improve patient outcomes.

The colorectal surgeon's personality may influence the rectal anastomotic decision. Colorectal Dis 2018; 20:970-980.

Abstract
AIM Colorectal surgeons regularly make the decision to anastomose, defunction or form an end colostomy when performing rectal surgery. This study aimed to define personality traits of colorectal surgeons and explore any influence of such traits on the decision to perform a rectal anastomosis. METHOD Fifty attendees of The Association of Coloproctology of Great Britain and Ireland 2016 Conference participated. After written consent, all underwent personality testing: alexithymia (inability to understand emotions), type of thinking process (intuitive versus rational) and personality traits (extraversion, agreeableness, openness, emotional stability, conscientiousness). Questions were answered regarding anastomotic decisions in various clinical scenarios and results analysed to reveal any influence of the surgeon's personality on anastomotic decision. RESULTS Participants were: male (86%), consultants (84%) and based in England (68%). Alexithymia was low (4%) with 81% displaying intuitive thinking (reflex, fast). Participants scored higher in emotional stability (ability to remain calm) and conscientiousness (organized, methodical) compared with population norms. Personality traits influenced the next anastomotic decision if: surgeons had recently received criticism at a departmental audit meeting; were operating with an anaesthetist that was not their regular one; or there had been no anastomotic leaks in their patients for over 1 year. CONCLUSION Colorectal surgeons have speciality relevant personalities that potentially influence the important decision to anastomose and could explain the variation in surgical practice across the UK. Future work should explore these findings in other countries and any link of personality traits to patient-related outcomes.

Abstract
AIM The determinants of cognitive impairment and delirium during acute illness are poorly understood, despite being common among older people. Anemia is common in older people, and there is ongoing debate regarding the association between anemia, cognitive impairment and delirium, primarily in non-surgical patients. METHODS Using data from the Older Persons Surgical Outcomes Collaboration 2013 and 2014 audit cycles, we examined the association between anemia and cognitive outcomes in patients aged ≥65 years admitted to five UK acute surgical units. On admission, the Confusion Assessment Method was carried out to detect delirium. Cognition was assessed using the Montreal Cognitive Assessment, and two levels of impairment were defined as Montreal Cognitive Assessment <26 and <20. Logistic regression models were constructed to examine these associations in all participants, and individuals aged ≥75 years only. RESULTS A total of 653 patients, with a median age of 76.5 years (interquartile range 73.0-80.0 years) and 53% women, were included. Statistically significant associations were found between anemia and age; polypharmacy; hyperglycemia; and hypoalbuminemia. There was no association between anemia and cognitive impairment or delirium. The adjusted odds ratios of cognitive impairment were 0.95 (95% CI 0.56-1.61) and 1.00 (95% CI 0.61-1.64) for the Montreal Cognitive Assessment <26 and <20, respectively. The adjusted odds ratio of delirium was 1.00 (95% CI 0.48-2.10) in patients with anemia compared with those without. Similar results were observed for the ≥75 years age group. CONCLUSIONS There was no association between anemia and cognitive outcomes among older people in this acute surgical setting. Considering the retrospective nature of the study and possible lack of power, findings should be taken with caution. Geriatr Gerontol Int 2018; 18: 1025-1030.

Abstract
PURPOSE Deciding to defunction after anterior resection can be difficult, requiring cognitive tools or heuristics. From our previous work, increasing age and risk-taking propensity were identified as heuristic biases for surgeons in Australia and New Zealand (CSSANZ), and inversely proportional to the likelihood of creating defunctioning stomas. We aimed to assess these factors for colorectal surgeons in the British Isles, and identify other potential biases. METHODS The Association of Coloproctology of Great Britain and Ireland (ACPGBI) was invited to complete an online survey. Questions included demographics, risk-taking propensity, sensitivity to professional criticism, self-perception of anastomotic leak rate and propensity for creating defunctioning stomas. Chi-squared testing was used to assess differences between ACPGBI and CSSANZ respondents. Multiple regression analysis identified independent surgeon predictors of stoma formation. RESULTS One hundred fifty (19.2%) eligible members of the ACPGBI replied. Demographics between ACPGBI and CSSANZ groups were well-matched. Significantly more ACPGBI surgeons admitted to anastomotic leak in the last year (p < 0.001). ACPGBI surgeon age over 50 (p = 0.02), higher risk-taking propensity across several domains (p = 0.044), self-belief in a lower-than-average anastomotic leak rate (p = 0.02) and belief that the average risk of leak after anterior resection is 8% or lower (p = 0.007) were all independent predictors of less frequent stoma formation. Sensitivity to criticism from colleagues was not a predictor of stoma formation. CONCLUSIONS Unrecognised surgeon factors including age, everyday risk-taking, self-belief in surgical ability and lower probability bias of anastomotic leak appear to exert an effect on decision-making in rectal surgery.

Abstract
Background and aim Lifestyle factor modification (alcohol, smoking, obesity, diet, physical activity) has the potential to reduce cancer incidence and cancer survival. This study assessed the knowledge of lifestyle factors and cancer in undergraduate medical students. Methods and results A total of 218 students (7 UK universities) completed an online survey of nine questions in three areas: knowledge (lifestyle factors and cancer); information sources; clinical practice (witnessed clinical counselling). Diet, alcohol, smoking and physical activity were recognised as lifestyle factors by 98% of responders, while only 69% reported weight. The links of lung cancer/smoking and alcohol/liver cancer were recognised by >90%, while only 10% reported weight or physical activity being linked to any cancer. University teaching on lifestyle factors and cancer was reported by 78%: 34% rating it good/very good. GPs were witnessed giving lifestyle advice by 85% of responders. Conclusions Most respondents were aware of a relationship between lifestyle factors and cancer, mainly as a result of undergraduate teaching. Further work may widen the breadth of knowledge, and potentially improve primary and secondary cancer prevention.

Lifestyle interventions are feasible in patients with colorectal cancer with potential short-term health benefits: a systematic review. Int J Colorectal Dis 2017; 32:765-775.

Abstract
PURPOSE Lifestyle interventions have been proposed to improve cancer survivorship in patients with colorectal cancer (CRC), but with treatment pathways becoming increasingly multi-modal and prolonged, opportunities for interventions may be limited. This systematic review assessed the evidence for the feasibility of performing lifestyle interventions in CRC patients and evaluated any short- and long-term health benefits. METHODS Using PRISMA Guidelines, selected keywords identified randomised controlled studies (RCTs) of lifestyle interventions [smoking, alcohol, physical activity (PA) and diet/excess body weight] in CRC patients. These electronic databases were searched in June 2015: Dynamed, Cochrane Database, OVID MEDLINE, OVID EMBASE, and PEDro. RESULTS Fourteen RCTs were identified: PA RCTs (n = 10) consisted mainly of telephone-prompted walking or cycling interventions of varied durations, predominately in adjuvant setting; dietary/excess weight interventions RCTs (n = 4) focused on low-fat and/or high-fibre diets within a multi-modal lifestyle intervention. There were no reported RCTs in smoking or alcohol cessation/reduction. PA and/or dietary/excess weight interventions reported variable recruitment rates, but good adherence and retention/follow-up rates, leading to short-term improvements in dietary quality, physical, psychological and quality-of-life parameters. Only one study assessed long-term follow-up, finding significantly improved cancer-specific survival after dietary intervention. CONCLUSIONS This is the first systematic review on lifestyle interventions in patients with CRC finding these interventions to be feasible with improvements in short-term health. Future work should focus on defining the optimal type of intervention (type, duration, timing and intensity) that not only leads to improved short-term outcomes but also assesses long-term survival.

Abstract
AIM Several modifiable and nonmodifiable health-related behaviours are associated with the incidence of colorectal cancer (CRC), but there is little research on their association with survival. This work aimed to investigate possible relationships between modifiable behavioural factors and outcomes on a study cohort of CRC patients undergoing potentially curative surgery. METHOD A retrospective cohort study was carried out of patients diagnosed with nonmetastatic CRC residing in the NHS Greater Glasgow and Clyde area, UK and undergoing elective curative surgery (January 2011 to December 2012). Data were obtained from the Scottish Cancer Registry, National Scottish Death Records. Preoperative assessment of smoking, alcohol consumption, nurse-measured body mass index (BMI) and exercise levels were recorded, and patients were followed until death or censorship. Survival analysis was carried out and proportional hazards assumptions were assessed graphically using plots and were then formally tested using the PHTEST procedure in stata. RESULT Of the initial 527 patients, 181 (34%) satisfied the inclusion criteria. The total duration of follow-up was 480 person-years. At the preoperative assessment, 75% of patients were overweight or obese, 10.6% were current smokers, 13.1% recorded excess alcohol consumption and 8.5% had physical difficulty climbing stairs. Age, BMI, histopathological stage and physical capacity all independently affected survival (P < 0.05). Overweight patients [hazard ratio (HR) 2.81] and those who had difficulty climbing stairs (HR 3.31) had a significantly poorer survival. CONCLUSION This study found evidence that preoperative exercise capacity and BMI are important independent prognostic factors of survival in patients undergoing curative surgery for CRC.

Abstract
Background Colonoscopy is currently the gold standard for detection of colorectal lesions, but may be limited in anatomically localising lesions. This audit aimed to determine the accuracy of colonoscopy lesion localisation, any subsequent changes in surgical management and any potentially influencing factors. Methods Patients undergoing colonoscopy prior to elective curative surgery for colorectal lesion/s were included from 8 registered U.K. sites (2012–2014). Three sets of data were recorded: patient factors (age, sex, BMI, screener vs. symptomatic, previous abdominal surgery); colonoscopy factors (caecal intubation, scope guide used, colonoscopist accreditation) and imaging modality. Lesion localisation was standardised with intra-operative location taken as the gold standard. Changes to surgical management were recorded. Results 364 cases were included; majority of lesions were colonic, solitary, malignant and in symptomatic referrals. 82% patients had their lesion/s correctly located at colonoscopy. Pre-operative CT visualised lesion/s in only 73% of cases with a reduction in screening patients (64 vs. 77%; p = 0.008). 5.2% incorrectly located cases at colonoscopy underwent altered surgical management, including conversion to open. Univariate analysis found colonoscopy accreditation, scope guide use, incomplete colonoscopy and previous abdominal surgery significantly influenced lesion localisation. On multi-variate analysis, caecal intubation and scope guide use remained significant (HR 0.35, 0.20–0.60 95% CI and 0.47; 0.25–0.88, respectively). Conclusion Lesion localisation at colonoscopy is incorrect in 18% of cases leading to potentially significant surgical management alterations. As part of accreditation, colonoscopists need lesion localisation training and awareness of when inaccuracies can occur.

Abstract
IntroductionPractice using simulators has been validated as a mean for surgical trainees to improve basic laparoscopic skills and free their attention for higher cognitive functions. However, mere provision of equipment does not result in frequent practice. This study assesses one approach to incentivising practice within core surgical training programmes and leads to further recommendations.Methods30 core surgical trainees (CST) starting laparoscopic-based specialties were recruited from East and West of Scotland CST programmes and given take-home laparoscopic simulators, with six training modules. Attainment of target metric scores generated an eCertificate, to be rewarded by progression in the live theatre. Questionnaires assessed confounding variables and explored CSTs’ anxieties about laparoscopy.Results27 trainees (90%) agreed to participate (mean age 28 years, range 24–25; 17 males). 13 CSTs (48%) were in the first year of surgical training. 11 (41%) had no previous simulation experience and 7 (32%) CSTs played video games >3 hours/week. 12 of 27 trainees (44%) completed ≥1 task and 7 completed all (26%).Performances improved in some participants, but overall engagement with the programme was poor. Reasons given included poor internet connectivity, busy rotations and examinations. CSTs who engaged in the study significantly reduced their anxiety (mean 4.96 vs 3.56, p<0.05).ConclusionsThe provision of take-home laparoscopic simulators with accompanying targets did not successfully incentivise CSTs to practise. However, the subgroup who did engage with the project reported performance improvements and significantly reduced anxiety. Proposals to overcome barriers to practising in simulation, including obligatory simulation-based assessments, are discussed.

Abstract
INTRODUCTION Older patients (>65 years of age) admitted as general surgical emergencies increasingly require improved recognition of their specific needs relative to younger patients. Two such needs are frailty and cognitive impairment. These are evolving research areas that the emergency surgeon increasingly requires knowledge of to improve short- and long-term patient outcomes. METHODS This paper reviews the evidence for frailty and cognitive impairment in the acute surgical setting by defining frailty and cognitive impairment, introducing methods of diagnosis, discussing the influence on prognosis and proposing strategies to improve older patient outcomes. RESULTS Frailty is present in 25% of the older surgical population. Using frailty-scoring tools, frailty was associated with a significantly longer hospital stay and higher mortality at 30 and 90 days after admission to an acute surgical unit. Cognitive impairment is present in a high number of older acute surgical patients (approximately 70%), whilst acute onset cognitive impairment, termed delirium, is documented in 18%. However, patients with delirium had significantly longer hospital stays and higher in-hospital mortality than those with cognitive impairment. CONCLUSIONS Improved knowledge of frailty and delirium by the emergency surgeon allows the specialised needs of older surgical patients to be taken into account. Early recognition, and consideration of minimally invasive surgery or radiological intervention alongside potentially transferable successful elective interventions such as comprehensive geriatric assessment, may help to improve short- and long-term patient outcomes in this vulnerable population.

Abstract
Background: Exercise during dialysis (EDD) in End-Stage Renal Disease (ESRD) has been documented as an effective intervention to improving a patient's aerobic capacity. Aims: This pilot study aimed to confirm physiological improvements, to establish its safety and practicality and to form guidelines for a long-term study, leading to the integration of EDD in ESRD therapy. Methods: A total of 17 patients on hospital haemodialysis were recruited: ten exercisers (age 42.4 ± 12.6) and six controls (age 41.0 ± 8.3). Both groups were initially tested for estimated VO2max, heart rate, blood pressure, leg extension peak torque, anxiety and depression levels, as well as biochemical and haematological values. The exercisers then underwent cycling ergometer exercise sessions during dialysis, twice weekly, for a total of 12 sessions. Both groups were re-tested after this period. Results: All test and exercise sessions were completed without complication. Compliance was high with only 1 exerciser failing to complete all 12 sessions. The exercisers showed a statistically significant increase (p < 0.05) in EDD workrates (44.3 to 52.1 watts) during the 12 sessions and a reduction in anxiety (p < 0.05). Statistical analysis showed no other significant changes in either group after the 6-week period. Conclusion: This pilot study has confirmed that aerobic EDD is feasible and well accepted by patients on hospital haemodialysis. EDD reduced anxiety scores and showed a trend for an improved level of aerobic fitness.

Abstract
OBJECTIVES Multimorbidity is the presence of 2 or more medical conditions. This increasingly used assessment has not been assessed in a surgical population. The objectives of this study were to assess the prevalence of multimorbidity and its association with common outcome measures. DESIGN A cross-sectional observational study. SETTING A UK-based multicentre study, included participants between July and October 2014. PARTICIPANTS Consecutive emergency (non-elective) general surgical patients admitted to hospital, aged over 65 years. OUTCOME MEASURES The outcome measures were (1) the prevalence of multimorbidity and (2) the association between multimorbidity and frailty; the rate and severity of surgery; length of hospital stay; readmission to hospital within 30 days of discharge; and death at 30 and 90 days. RESULTS Data were collected on 413 participants aged 65-98 years (median 77 years, (IQR (70-84)). 51.6% (212/413) participants were women. Multimorbidity was present in 74% (95% CI 69.7% to 78.2%) of the population and increased with age (p<0.0001). Multimorbidity was associated with increasing frailty (p for trend <0.0001). People with multimorbidity underwent surgery as often as those without multimorbidity, including major surgery (p=0.03). When comparing multimorbid people with those without multimorbidity, we found no association between length of hospital stay (median 5 days, IQR (1-54), vs 6 days (1-47), (p=0.66)), readmission to hospital (64 (21.1%) vs 18 (16.8%) (p=0.35)), death at 30 days (14 (4.6%) vs 6 (5.6%) (p=0.68)) or 90-day mortality (28 (9.2%) vs 8 (7.6%) (p=0.60)). CONCLUSIONS AND IMPLICATIONS Multimorbidity is common. Nearly three-quarters of this older emergency general surgical population had 2 or more chronic medical conditions. It was strongly associated with age and frailty, and was not a barrier to surgical intervention. Multimorbidity showed no associations across a range of outcome measures, as it is currently defined. Multimorbidity should not be relied on as a useful clinical tool in guidelines or policies for older emergency surgical patients.

Abstract
BACKGROUND The purpose of the study is to examine the prevalence of hyperglycaemia in an older acute surgical population and its effect on clinically relevant outcomes in this setting. METHODS Using Older Persons Surgical Outcomes Collaboration (OPSOC) multicentre audit data 2014, we examined the prevalence of admission hyperglycaemia, and its effect on 30-day and 90-day mortality, readmission within 30 days and length of acute hospital stay using logistic regression models in consecutive patients, ≥65 years, admitted to five acute surgical units in the UK hospitals in England, Scotland and Wales. Patients were categorised in three groups based on their admission random blood glucose: <7.1, between 7.1 and 11.1 and ≥11.1 mmol/L. RESULTS A total of 411 patients (77.25±8.14 years) admitted during May and June 2014 were studied. Only 293 patients (71.3%) had glucose levels recorded on admission. The number (%) of patients with a blood glucose <7.1, 7.1-11.1 and ≥11.1 mmol/L were 171 (58.4), 99 (33.8) and 23 (7.8), respectively. On univariate analysis, admission hyperglycaemia was not predictive of any of the outcomes investigated. Although the characteristics of those with no glucose level were not different from the included sample, 30-day mortality was significantly higher in those who had not had their admission glucose level checked (10.2% vs 2.7%), suggesting a potential type II error. CONCLUSION Despite current guidelines, nearly a third of older people with surgical diagnoses did not have their glucose checked on admission highlighting the challenges in prognostication and evaluation research to improve care of older frail surgical patients.
