Factors associated with stoma formation in ileocolic resection for Crohn's disease and the development of a predictive scoring system.

PURPOSE: The likelihood of a stoma following ileocolic resection (ICR) for Crohn's disease (CD) is an important consideration. This study aims to identify the factors associated with an increased likelihood of a stoma and develop a predictive scoring system (SS). METHODS: Patient data were collected from St. Marks Hospital, London, UK and Humanitas Clinical and Research Center, Milan, Italy, on all patients who underwent an ICR for CD from 2005 to 2017. A logistic regression analysis was used for multivariate analysis. The SS was developed from the logistic regression model. The performance of the SS was evaluated using receiver operating characteristics area under the curve (AUROC). RESULTS: A total of 628 surgeries were included in the analysis. Sixty-nine surgeries were excluded due to missing data. The remaining 559 were divided into two cohorts for the scoring system's development (n = 434) and validation (n = 125). The regression model was statistically significant (p < 0.0001). The statistically significant independent variables included sex, preoperative albumin and haemoglobin levels, surgical access and simultaneous colonic resection. The AUROC for the development and validation cohorts were 0.803 and 0.905, respectively (p < 0.0001). Youden's index suggested the cut-off score of - 95.9, with a sensitivity of 87.6% and a specificity of 62.9%. CONCLUSIONS: Male sex, low preoperative albumin, anaemia, laparoscopic conversion and simultaneous colonic resection were associated with an increased likelihood of requiring a stoma and were used to develop an SS.

A scoring system to predict a prolonged length of stay after surgery for Crohn's disease.

AIM: Many factors influence the postoperative length of stay (LOS) in Crohn's disease (CD). This study aims to identify the factors associated with a prolonged LOS after ileocolic resection (ICR) for CD and to develop a scoring system to predict the postoperative LOS in CD. METHOD: Patient data were collected from St Marks Hospital, London, UK, and the Humanitas Clinical and Research Center Milan, Italy, for all patients who underwent an ICR for CD from 2005 to 2017. Logistic regression was used for multivariate analysis. The scoring system was developed from the logistic regression model. The performance of the scoring system was evaluated using the area under the receiver operating characteristic curve (AUROC). RESULTS: A total of 628 surgeries were included in the analysis. Eighty eight surgeries were excluded due to missing data. The remaining 543 were divided into two cohorts for the development (n = 418) and validation (n = 125) of the scoring system. The regression model was statistically significant (p < 0.0001). The statistically significant independent variables included the time since diagnosis, American Society of Anesthesiologists (ASA) grade, perioperative use of steroids, surgical access, strictureplasty and platelet count. The AUROCs for the development and validation cohorts were 0.732 and 0.7, respectively (p < 0.0001). The cut-off score suggested by Youden's index was 50, with a sensitivity of 65.6% and a specificity of 73.3%. CONCLUSION: The time since diagnosis, ASA grade, steroid use, surgical access, strictureplasty and platelet count were associated with a prolonged LOS and were used to develop a scoring system.

Establishing the aims, format and function for multidisciplinary team-driven care within an inflammatory bowel disease service: a multicentre qualitative specialist-based consensus study.

OBJECTIVE: To obtain a specialist-based consensus on the aims, format and function for MDT-driven care within an inflammatory bowel disease (IBD) service. DESIGN: This was a prospective, multicentre study using a Delphi formal consensus-building methodology. SETTING: Participants were recruited nationally across 13 centres from July to August 2014. PARTICIPANTS: 24 participants were included into the Delphi Specialist Consensus Panel. They included six consultant colorectal surgeons, six gastroenterologists, five consultant radiologists, three consultant histopathologists and 4 IBD nurse specialists. INTERVENTIONS: Panellists ranked items on a Likert scale (1=not important to 5=very important). Items with a median score >3 were considered eligible for inclusion. MAIN OUTCOME MEASURES: Consensus was defined with an IQR ≤1. Consensus on categorical responses was defined by an agreement of >60%. RESULTS: A consensus on items (median; IQR) that described the aims of the MDT-driven care that were considered very important included: advance patient care (5;5-5), provide multidisciplinary input for the patient's care plan (5;5-5), provide shared experience and expertise (5;5-5), improve patient outcome (5;5-5), deliver the best possible care for the patient (5;5-5) and to obtain consensus on management for a patient with IBD (5;4-5). A consensus for being a core MDT member was demonstrated for colorectal surgeons (24/24), radiologists (24/24), gastroenterologists (24/24), nurse specialists (24/24), dieticians (14/23), histopathologists (21/23) and coordinators (21/24). CONCLUSIONS: This study has provided a consensus for proposed aims, overall design, format and function MDT-driven care within an IBD service. This can provide a focus for core members, and aid a contractual recognition to ensure attendance and proactive contribution.

Establishing Key Performance Indicators [KPIs] and Their Importance for the Surgical Management of Inflammatory Bowel Disease-Results From a Pan-European, Delphi Consensus Study.

BACKGROUND AND AIMS: Key performance indicators [KPIs] exist across a range of areas in medicine. They help to monitor outcomes, reduce variation, and drive up standards across services. KPIs exist for inflammatory bowel disease [IBD] care, but none specifically cover inflammatory bowel disease [IBD] surgical service provision. METHODS: This was a consensus-based study using a panel of expert IBD clinicians from across Europe. Items were developed and fed through a Delphi process to achieve consensus. Items were ranked on a Likert scale from 1 [not important] to 5 [very important]. Consensus was defined when the inter quartile range was ≤ 1, and items with a median score > 3 were considered for inclusion. RESULTS: A panel of 21 experts [14 surgeons and 7 gastroenterologists] was recruited. Consensus was achieved on procedure-specific KPIs for ileocaecal and perianal surgery for Crohn's disease, [N = 10] with themes relating to morbidity [N = 7], multidisciplinary input [N = 2], and quality of life [N = 1]; and for subtotal colectomy, proctocolectomy and ileoanal pouch surgery for ulcerative colitis [N = 11], with themes relating to mortality [N = 2], morbidity [N = 8], and service provision [N = 1]. Consensus was also achieved for measures of the quality of IBD surgical service provision and quality assurance in IBD surgery. CONCLUSIONS: This study has provided measurable KPIs for the provision of surgical services in IBD. These indicators cover IBD surgery in general, the governance and structures of the surgical services, and separate indicators for specific subareas of surgery. Monitoring of IBD services with these KPIs may reduce variation across services and improve quality.

Determining Predictors for Intra-abdominal Septic Complications Following Ileocolonic Resection for Crohn's Disease-Considerations in Pre-operative and Peri-operative Optimisation Techniques to Improve Outcome.

BACKGROUND AND AIMS: Intra-abdominal septic complications [IASC] following ileocolonic resection for Crohn's disease are common. Determining risk factors for these complications can aid pre-operative and peri-operative strategies to reduced morbidity. This study aims to determine the incidence and predictors of intra-abdominal septic complications following ileocolonic resection for Crohn's disease. METHODS: A single-centre, retrospective study was conducted. The clinical case notes of patients with histopathologically proven Crohn's disease, who underwent an ileocolonic resection as a one-stage or two-stage procedure, were reviewed. The primary endpoint was the formation of intra-abdominal septic complications within a 30-day post-operative time frame. RESULTS: Overall 163 patients underwent 175 ileocolonic procedures. Post-operative intra-abdominal septic complications were demonstrated in 9% [13/142] of one-stage procedures and 12% [4/33] of two-stage procedures [p = 0.2]. Post-operative IASCs following a one-stage procedure demonstrated associations with smokers [p = 0.004], intraoperative abdominal sepsis [p = 0.005], concomitant upper gastrointestinal Crohn's [p = 0.015], the presence of peri-operative anaemia [p = 0.037], hypoalbuminaemia [< 25g/l] [p = 0.04], and histologically involved margins [p = 0.001]. Multivariate analysis demonstrated the presence of intra-abdominal sepsis (hazard ratio [HR] 8.6, 95% confidence interval [CI]: 1.2 60.1] and the use of peri-operative biologicals [HR 24.6, 95% CI: 2.0-298] as independent predictors of post-operative intra-abdominal septic complications. CONCLUSIONS: This study highlights specific variables that may be contributory to poor outcome. These findings may be important when optimising patients for surgery, as well as planning an appropriate operative strategy. Further prospective studies and a larger sample size are required to validate these findings.

Defining the optimal design of the inflammatory bowel disease multidisciplinary team: results from a multicentre qualitative expert-based study.

OBJECTIVE: To elicit expert views to define the aims, optimal design, format and function of an inflammatory bowel disease (IBD) multidisciplinary team (MDT) with the overall purpose of enhancing the quality of MDT-driven care within an IBD service provision. DESIGN: This study was a multicentre, prospective, qualitative study using a standard semistructured interview methodology. PARTICIPANTS: A multidisciplinary sample of 28 semistructured interviews of which there are six consultant colorectal surgeons, six IBD nurse specialists, seven consultant gastroenterologists, five consultant radiologists and four consultant histopathologists. SETTING: Participants were recruited from 10 hospitals, which were a mixture of community hospitals and specialist IBD centres between June and October 2013. RESULTS: Experts argued that the main goal of MDT-driven IBD care is to improve patient outcomes via sharing collective expertise in a formalised manner. Themes regarding the necessary requirements for an IBD MDT to occur included good attendance, proactive contribution, a need to define core members and appropriate and functional computer facilities. Emergent themes regarding the logistics of an effective IBD MDT included an eligibility criterion for case selection and discussion and appropriate scheduling. Themes regarding the overall design of the IBD MDT included a 'hub-and-spoke' model versus a 'single-centre' model. CONCLUSIONS: Defining key elements for an optimal design format for the IBD MDT is necessary to ensure quality of care and reduce variation in care standards. This study has produced a set of expert-based standards that can be used to structure the IBD MDT. These standards now require larger scale validation and consensus prior to becoming a practical guideline for the management of IBD care.
