Validation of the emergency surgery score (ESS) in a UK patient population and comparison with NELA scoring: a retrospective multicentre cohort study.

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.

SF-CORNER (splenic flexure colorectal cancer): an international survey of operative approaches and outcomes for cancers of the splenic flexure.

AIM: The optimum surgical approach to splenic flexure cancers (SFCs) remains uncertain. The aim of this survey was to explore the opinions of an international surgical community on the management and outcomes of SFC. METHOD: A questionnaire was constructed comprising five sections (information about respondents; definition and prognosis of SFC; operative approach; approach in specific scenarios; outcomes) and circulated through an international dissemination committee and social media. RESULTS: The survey received 576 responses over 4 weeks across 50 countries. There was no consensus regarding the definition of the splenic flexure, whilst the proportion of respondents who did and did not think that patients with SFC had a worse outcome was equal. The overall preferred operative approach was left hemicolectomy [203 (35.2%)], followed by segmental resection [167 (29%)], extended right hemicolectomy [126 (21.9%)] and subtotal colectomy [7 (12%)]. The stated pedicles for ligation varied between resection types and also within the same resection. One hundred and sixty-six (28.8%) respondents thought a segmental resection was associated with the worst survival and 190 (33%) thought it was associated with the best quality of life. CONCLUSION: This survey confirms a lack of consensus across all aspects SFC treatment. The differing approaches described are likely to represent different beliefs around the variable anatomy of this region and the associated lymphatic drainage. Future studies are required to address such inconsistencies and identify the optimum surgical strategy, whilst also incorporating quality-of-life metrics and patient-reported outcomes. A one-size-fits-all approach is probably not appropriate with SFC, and a more bespoke approach is required.

Beyond high-risk: analysis of the outcomes of extreme-risk patients in the National Emergency Laparotomy Audit.

Patients who require emergency laparotomy are defined as high risk if their 30-day predicted risk of mortality is ≥ 5%. Despite a large difference in the characteristics of patients with a mortality risk score of between 5% and 50%, these outcomes are aggregated by the National Emergency Laparotomy Audit (NELA). Our aim was to describe the outcomes of the cohort of patients at extreme risk of death, which we defined as having a NELA-predicted 30-day mortality of ≥ 50%. All patients enrolled in the NELA database between December 2012 and 2020 were included. We compared patient characteristics; length of hospital stay; rates of unplanned return to the operating theatre; and 90-day survival in extreme-risk groups (predicted ≥ 50%) and high-risk patients (predicted 5-49%). Of 161,337 patients, 5193 (3.2%) had a predicted mortality of ≥ 50%. When patients were further subdivided, 2437 (47%) had predicted mortality of 50-59% (group 50-59); 1484 (29%) predicted mortality of 60-69% (group 60-69); 840 (16%) predicted mortality of 70-79% (group 70-79); and 423 (8%) predicted mortality of ≥ 80% (group 80+). Extreme-risk patients were significantly more likely to have been admitted electively than high-risk patients (p < 0.001). Length of stay increased from a median (IQR [range]) of 26 (16-43 [0-271]) days in group 50-59 to 35 (21-56 [0-368]) days in group 80+, compared with 17 (10-30 [0-1136]) days for high-risk patients. Rates of unplanned return to the operating theatre were higher in extreme-risk groups compared with high-risk patients (11% vs. 8%). The 90-day survival was 43% in group 50-59, 34% in group 60-69, 27% in group 70-79 and 17% in group 80+. These data underscore the need for a differentiated approach when discussing risk with patients at extreme risk of mortality following an emergency laparotomy. Clinicians should focus on patient priorities on quantity and quality of life during informed consent discussions before surgery. Future work should extend beyond the immediate postoperative period to encompass the longer-term outcomes (survival and function) of patients who have emergency laparotomies.

CT-derived measures of muscle quantity and quality predict poorer outcomes from elective colorectal surgery: a UK multicentre retrospective cohort study.

PURPOSE: To assess whether preoperative radiologically defined lean muscle measures are associated with adverse clinical outcomes in patients undergoing elective surgery for colorectal cancer. METHODS: This retrospective UK-based multicentre data collection study identified patients having had colorectal cancer resection with curative intent between January 2013 to December 2016. Preoperative computed-tomography (CT) scans were used to measure psoas muscle characteristics. Clinical records provided postoperative morbidity and mortality data. RESULTS: This study included 1122 patients. The cohort was separated into a combined group (patients with both sarcopenia and myosteatosis) and others group (either sarcopenia or myosteatosis, or neither). For the combined group, anastomotic leak was predicted on univariate (OR 4.1, 95% CI 1.43-11.79; p = 0.009) and multivariate analysis (OR 4.37, 95% CI 1.41-13.53; p = 0.01). Also for the combined group, mortality (up to 5 years postoperatively) was predicted on univariate (HR 2.41, 95% CI 1.64-3.52; p < 0.001) and multivariate analysis (HR 1.93, 95% CI 1.28-2.89; p = 0.002). A strong correlation exists between freehand-drawn region of interest-derived psoas density measurement and using the ellipse tool (R2 = 81%; p < 0.001). CONCLUSION: Measures of lean muscle quality and quantity, which predict important clinical outcomes, can be quickly and easily taken from routine preoperative imaging in patients being considered for colorectal cancer surgery. As poor muscle mass and quality are again shown to predict poorer clinical outcomes, these should be proactively targeted within prehabilitation, perioperative and rehabilitation phases to minimise negative impact of these pathological states.

Quantitative futility in emergency laparotomy: an exploration of early-postoperative death in the National Emergency Laparotomy Audit.

BACKGROUND: Quantitative futility is an appraisal of the risk of failure of a treatment. For those who do not survive, a laparotomy has provided negligible therapeutic benefit and may represent a missed opportunity for palliation. The aim of this study was to define a timeframe for quantitative futility in emergency laparotomy and investigate predictors of futility using the National Emergency Laparotomy Audit (NELA) database. METHODS: A two-stage methodology was used; stage one defined a timeframe for futility using an online survey and steering group discussion; stage two applied this definition to patients enrolled in NELA December 2013-December 2020 for analysis. Futility was defined as all-cause mortality within 3 days of emergency laparotomy. Baseline characteristics of this group were compared to all others. Multilevel logistic regression was carried out with potentially clinically important predictors defined a priori. RESULTS: Quantitative futility occurred in 4% of patients (7442/180,987). Median age was 74 years (range 65-81 years). Median NELA risk score was 32.4% vs. 3.8% in the surviving cohort (p < 0.001). Early mortality patients more frequently presented with sepsis (p < 0.001). Significant predictors of futility included age, arterial lactate and cardiorespiratory co-morbidity. Frailty was associated with a 38% increased risk of early mortality (95% CI 1.22-1.55). Surgery for intestinal ischaemia was associated with a two times greater chance of futile surgery (OR 2.67; 95% CI 2.50-2.85). CONCLUSIONS: Quantitative futility after emergency laparotomy is associated with quantifiable risk factors available to decision-makers preoperatively. These findings should be incorporated qualitatively by the multidisciplinary team into shared decision-making discussions with extremely high-risk patients.

Decision making in emergency laparotomy: the role of predicted life expectancy.

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.

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.

The management of adult appendicitis during the COVID-19 pandemic: an interim analysis of a UK cohort study.

BACKGROUND: Acute appendicitis (AA) is the most common general surgical emergency. Early laparoscopic appendicectomy is the gold-standard management. SARS-CoV-2 (COVID-19) brought concerns of increased perioperative mortality and spread of infection during aerosol generating procedures: as a consequence, conservative management was advised, and open appendicectomy recommended when surgery was unavoidable. This study describes the impact of the first weeks of the pandemic on the management of AA in the United Kingdom (UK). METHODS: Patients 18 years or older, diagnosed clinically and/or radiologically with AA were eligible for inclusion in this prospective, multicentre cohort study. Data was collected from 23rd March 2020 (beginning of the UK Government lockdown) to 1st May 2020 and included: patient demographics, COVID status; initial management (operative and conservative); length of stay; and 30-day complications. Analysis was performed on the first 500 cases with 30-day follow-up. RESULTS: The patient cohort consisted of 500 patients from 48 sites. The median age of this cohort was 35 [26-49.75] years and 233 (47%) of patients were female. Two hundred and seventy-one (54%) patients were initially treated conservatively; with only 26 (10%) cases progressing to an operation. Operative interventions were performed laparoscopically in 44% (93/211). Median length of hospital stay was significantly reduced in the conservatively managed group (2 [IQR 1-4] days vs. 3 [2-4], p < 0.001). At 30 days, complications were significantly higher in the operative group (p < 0.001), with no deaths in any group. Of the 159 (32%) patients tested for COVID-19 on admission, only 6 (4%) were positive. CONCLUSION: COVID-19 has changed the management of acute appendicitis in the UK, with non-operative management shown to be safe and effective in the short-term. Antibiotics should be considered as the first line during the pandemic and perhaps beyond.

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.

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.

Prehabilitation in elective abdominal cancer surgery in older patients: systematic review and meta-analysis.

BACKGROUND: Prehabilitation has emerged as a strategy to prepare patients for elective abdominal cancer surgery with documented improvements in postoperative outcomes. The aim of this study was to assess the evidence for prehabilitation interventions of relevance to the older adult. METHODS: Systematic searches were conducted using MEDLINE, Web of Science, Scopus, CINAHL and PsychINFO. Studies of preoperative intervention (prehabilitation) in patients undergoing abdominal cancer surgery reporting postoperative outcomes were included. Age limits were not set as preliminary searches revealed this would be too restrictive. Articles were screened and selected based on PRISMA guidelines, and assessment of bias was performed. Qualitative, quantitative and meta-analyses of data were conducted as appropriate. RESULTS: Thirty-three studies (3962 patients) were included. Interventions included exercise, nutrition, psychological input, comprehensive geriatric assessment and optimization, smoking cessation and multimodal (two or more interventions). Nine studies purposely selected high-risk, frail or older patients. Thirty studies were at moderate or high risk of bias. Ten studies individually reported benefits in complication rates, with meta-analyses for overall complications demonstrating significant benefit: multimodal (risk difference -0·1 (95 per cent c.i. -0·18 to -0·02); P = 0·01, I2  = 18 per cent) and nutrition (risk difference -0·18 (-0·26 to -0·10); P < 0·001, I2  = 0 per cent). Seven studies reported reductions in length of hospital stay, with no differences on meta-analysis. CONCLUSION: The conclusions of this review are limited by the quality of the included studies, and the heterogeneity of interventions and outcome measures reported. Exercise, nutritional and multimodal prehabilitation may reduce morbidity after abdominal surgery, but data specific to older patients are sparse.

ANTECEDENTES: La pre-habilitación ha surgido como una estrategia para preparar a los pacientes para la cirugía electiva del cáncer abdominal con mejoras documentadas en los resultados postoperatorios. El objetivo de este estudio fue evaluar la evidencia sobre las intervenciones de pre-habilitación relevantes en adultos de edad avanzada. MÉTODOS: Se realizaron búsquedas sistemáticas utilizando MEDLINE, Web of Science, Scopus, CINAHL y PsychINFO. Registro PROSPERO: CRD42019120381. Se incluyeron estudios de intervención preoperatoria (pre-habilitación) en pacientes sometidos a cirugía oncológica abdominal que describiesen resultados postoperatorios. No se fijaron límites en la edad dado que las búsquedas preliminares revelaron que ello sería demasiado restrictivo. Los artículos fueron examinados y seleccionados en base a las guías PRISMA y se realizó una evaluación del sesgo. Se llevó a cabo un análisis cualitativo, cuantitativo y metaanálisis de los datos según fuese apropiado. RESULTADOS: Se incluyeron 33 estudios (3.962 patients). Las intervenciones incluyeron ejercicio, nutrición, intervención psicológica, evaluación geriátrica global y optimización, abandono del tabaquismo y multimodal (dos o más intervenciones). Nueve estudios seleccionaron expresamente una población de pacientes de elevado riesgo, frágiles o de edad avanzada. Treinta estudios presentaban un riesgo moderado/alto de sesgo. Diez estudios describieron de forma individual beneficios en las tasas de complicaciones con metaanálisis para las complicaciones globales demostrando un beneficio significativo: multimodal (diferencia de riesgo -0,1 (i.c. del 95% −0,18 a −0,02); P = 0,01, I2 = 18%) e intervención nutricional (diferencia de riesgo −0,18 (i.c. del 95% −0,26 a −0,10); P < 0,001, I2 = 0%). Siete estudios describieron reducciones en la duración de la estancia hospitalaria, sin diferencias en el metaanálisis. CONCLUSIÓN: Las conclusiones de esta revisión están limitadas por la calidad de los estudios incluidos, heterogeneidad de las intervenciones y descripción de las medidas de resultados. Las intervenciones de pre-habilitación de ejercicio, nutricionales y multimodales puede reducir la morbilidad tras cirugía abdominal, pero los datos concretos en pacientes de edad avanzada son escasos.

Frailty in older patients undergoing emergency colorectal surgery: USA National Surgical Quality Improvement Program analysis.

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.

ANTECEDENTES: la fragilidad se asocia con la edad avanzada y puede ocasionar resultados adversos postoperatorios. Un presunto aumento de la población mayor que necesita cirugía colorrectal urgente fue el motivo de efectuar este estudio sobre la prevalencia e impacto de la fragilidad. MÉTODOS: Pacientes mayores (definidos como ≥ 65 años por Medicare y la Oficina del Censo de los Estados Unidos) sometidos a resección colorrectal de urgencia fueron identificados a partir de la base de datos poblacional del ACS-NSQIP desde 2012 a 2016. Se calculó el índice de fragilidad modificado de 5 factores (5-factor modified frailty index, mFI-5), y los pacientes se estratificaron en grupos de 0, 1, y 2+. Las medidas de los resultados principales fueron la prevalencia y el impacto de la fragilidad en la morbilidad postoperatoria a los 30 días, mortalidad, reoperación, duración de la estancia hospitalaria (length of stay, LOS), destino al alta y reingreso. RESULTADOS: De 10.131 pacientes, 31,2% (n = 3.129) eran frágiles/mFI-5 de 2+ con una mediana de edad de 75 años y 41,8% eran varones. La mayoría tenían una puntuación ASA 3 o mayor (n = 87,7%), aparecieron complicaciones mayores en un tercio de los pacientes y la mortalidad postoperatoria fue del 15,9%. Se observó una LOS prolongada en 52,0% y 11,0% fueron reingresados. Aunque la gran mayoría (88%) vivían de forma independiente antes de la cirugía, solo el 45,4% fueron dados de alta directamente a su domicilio. Un mFI-5 of 2+ predijo mortalidad, morbilidad global y mayor, reoperación, LOS prolongada, alta a una institución, y reingreso, pero la fragilidad fue independiente del género. CONCLUSIÓN: La fragilidad se asoció con morbilidad, mortalidad y pérdida de independencia en pacientes mayores que necesitan cirugía colorrectal de urgencia.

Nosocomial COVID-19 infection: examining the risk of mortality. The COPE-Nosocomial Study (COVID in Older PEople).

BACKGROUND: Hospital admissions for non-coronavirus disease 2019 (COVID-19) pathology have decreased significantly. It is believed that this may be due to public anxiety about acquiring COVID-19 infection in hospital and the subsequent risk of mortality. AIM: To identify patients who acquire COVID-19 in hospital (nosocomial COVID-19 infection (NC)) and their risk of mortality compared to those with community-acquired COVID-19 (CAC) infection. METHODS: The COPE-Nosocomial Study was an observational cohort study. The primary outcome was the time to all-cause mortality (estimated with an adjusted hazard ratio (aHR)), and secondary outcomes were day 7 mortality and the time-to-discharge. A mixed-effects multivariable Cox's proportional hazards model was used, adjusted for demographics and comorbidities. FINDINGS: The study included 1564 patients from 10 hospital sites throughout the UK, and one in Italy, and collected outcomes on patients admitted up to April 28th, 2020. In all, 12.5% of COVID-19 infections were acquired in hospital; 425 (27.2%) patients with COVID died. The median survival time in NC patients was 14 days compared with 10 days in CAC patients. In the primary analysis, NC infection was associated with lower mortality rate (aHR: 0.71; 95% confidence interval (CI): 0.51-0.98). Secondary outcomes found no difference in day 7 mortality (adjusted odds ratio: 0.79; 95% CI: 0.47-1.31), but NC patients required longer time in hospital during convalescence (aHR: 0.49, 95% CI: 0.37-0.66). CONCLUSION: The minority of COVID-19 cases were the result of NC transmission. No COVID-19 infection comes without risk, but patients with NC had a lower risk of mortality compared to CAC infection; however, caution should be taken when interpreting this finding.

Exploring shared surgical decision-making from the patient's perspective: is the personality of the surgeon important?

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.

Does prehabilitation modify muscle mass in patients with rectal cancer undergoing neoadjuvant therapy? A subanalysis from the REx randomised controlled trial.

BACKGROUND: Patients with rectal cancer who present with sarcopenia (low muscle mass) are at significantly greater risk of postoperative complications and reduction in disease-free survival. We performed a subanalysis of a randomised controlled study [the REx trial; www.isrctn.com ; 62859294] to assess the potential of prehabilitation to modify muscle mass in patients having neoadjuvant chemoradiotherapy (NACRT). METHODS: Patients scheduled for NACRT, then potentially curative surgery (August 2014-March 2016) had baseline physical assessment and psoas muscle mass measurement (total psoas index using computed tomography-based measurements). Participants were randomised to either the intervention (13-17-week telephone-guided graduated walking programme) or control group (standard care). Follow-up testing was performed 1-2 weeks before surgery. RESULTS: The 44 patients had a mean age of 66.8 years (SD 9.6) and were male (64%); white (98%); American Society of Anesthesiologists class 2 (66%); co-morbid (58%); overweight (72%) (body mass index ≥ 25 kg/m2). At baseline, 14% were sarcopenic. At follow-up, 13 (65%) of patients in the prehabilitation group had increased muscle mass versus 7 (35%) that experienced a decrease. Conversely, 16 (67%) controls experienced a decrease in muscle mass and 8 (33%) showed an increase. An adjusted linear regression model estimated a mean treatment difference in Total Psoas Index of 40.2mm2/m2 (95% CI - 3.4 to 83.7) between groups in change from baseline (p = 0.07). CONCLUSIONS: Prehabilitation improved muscle mass in patients with rectal cancer who had NACRT. These results need to be explored in a larger trial to determine if the poorer short- and long-term patient outcomes associated with low muscle mass can be minimised by prehabilitation.

Liquid biopsy for cancer diagnosis using vibrational spectroscopy: systematic review.

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.

la espectroscopia vibracional (vibrational spectroscopy, VS) es un dispositivo mínimamente invasivo para analizar material biológico y detectar enfermedad. Este estudio se propuso revisar su aplicación en la sangre humana para el diagnóstico de cáncer. MÉTODOS: Se llevó a cabo una revisión sistemática utilizando una búsqueda con palabras claves en bases de datos electrónicas (MEDLINE, EMBASE, PubMed, TRIP, Cochrane Library), de todos los manuscritos originales publicados en inglés que examinaban la utilización del análisis espectral vibracional de la sangre humana para la detección del cáncer. Se excluyeron estudios que incluían menos de 75 pacientes en los grupos cáncer/control, estudios en animales o cuando la muestra principal no fuera la sangre. RESULTADOS: De los 1.446 resultados, 6 estudios publicados en 2010-2018, y que examinaban cánceres del cerebro, vejiga, oral, mama, esófago e hígado cumplieron los criterios de inclusión, con una población total de 2.506 casos (1.316 cánceres, 1.076 controles; 1.476 varones, 915 mujeres). Para la detección del cáncer, las sensibilidades medias descritas en cada uno de los estudios incluidos variaron entre 79,3-98,0%, con especificidades entre 82,8-95,0%, y exactitudes diagnósticas entre 81,1% y 97,1%. La heterogeneidad en las estrategias descritas, métodos y medidas de resultados hicieron que el metaanálisis fuera inapropiado. CONCLUSIÓN: La VS muestra un alto potencial para el diagnóstico del cáncer, pero hasta que no se llegue a un acuerdo en los métodos para informar de los resultados y se hayan efectuado estudios con un tamaño muestral adecuado para una clasificación válida de los modelos, su valor en la práctica clínica sigue siendo incierto.

Decision-making for older patients undergoing emergency laparotomy: defining patient and clinician values and priorities.

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.
