AGA Clinical Practice Guideline on the Management of Pouchitis and Inflammatory Pouch Disorders.

BACKGROUND & AIMS: Pouchitis is the most common complication after restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis. This American Gastroenterological Association (AGA) guideline is intended to support practitioners in the management of pouchitis and inflammatory pouch disorders. METHODS: A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to prioritize clinical questions, identify patient-centered outcomes, conduct an evidence synthesis, and develop recommendations for the prevention and treatment of pouchitis, Crohn's-like disease of the pouch, and cuffitis. RESULTS: The AGA guideline panel made 9 conditional recommendations. In patients with ulcerative colitis who have undergone ileal pouch-anal anastomosis and experience intermittent symptoms of pouchitis, the AGA suggests using antibiotics for the treatment of pouchitis. In patients who experience recurrent episodes of pouchitis that respond to antibiotics, the AGA suggests using probiotics for the prevention of recurrent pouchitis. In patients who experience recurrent pouchitis that responds to antibiotics but relapses shortly after stopping antibiotics (also known as "chronic antibiotic-dependent pouchitis"), the AGA suggests using chronic antibiotic therapy to prevent recurrent pouchitis; however, in patients who are intolerant to antibiotics or who are concerned about the risks of long-term antibiotic therapy, the AGA suggests using advanced immunosuppressive therapies (eg, biologics and/or oral small molecule drugs) approved for treatment of inflammatory bowel disease. In patients who experience recurrent pouchitis with inadequate response to antibiotics (also known as "chronic antibiotic-refractory pouchitis"), the AGA suggests using advanced immunosuppressive therapies; corticosteroids can also be considered in these patients. In patients who develop symptoms due to Crohn's-like disease of the pouch, the AGA suggests using corticosteroids and advanced immunosuppressive therapies. In patients who experience symptoms due to cuffitis, the AGA suggests using therapies that have been approved for the treatment of ulcerative colitis, starting with topical mesalamine or topical corticosteroids. The panel also proposed key implementation considerations for optimal management of pouchitis and Crohn's-like disease of the pouch and identified several knowledge gaps and areas for future research. CONCLUSIONS: This guideline provides a comprehensive, patient-centered approach to the management of patients with pouchitis and other inflammatory conditions of the pouch.

A Case of Upper Gastrointestinal Bleeding Due to Metastatic High-Grade B-Cell Lymphoma Successfully Treated With Chemotherapy.

Upper gastrointestinal bleeding (UGIB) is a common and potentially life-threatening condition. Metastatic disease is an exceedingly rare cause of UGIB. We report the case of a 73-year-old man with high-grade B-cell lymphoma (HGBL) who presented for the initiation of chemotherapy and was found to be acutely anemic due to UGIB. An esophagogastroduodenoscopy (EGD) revealed multiple large, discrete, ulcerated, non-circumferential, and friable masses in the stomach. Biopsies were consistent with HGBL. The patient was urgently initiated on chemotherapy with the resolution of lesions on subsequent EGD. The rate of prevalence of gastric metastases is unknown, but it should be considered in patients with active malignancy who present with signs of UGIB.

Clinical codes combined with procedure codes increase diagnostic accuracy of Crohn's disease in a US Military health record.

Background and aims: Previous examinations of International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes to predict accuracy of diagnosis in inflammatory bowel disease have had limited chart review to confirm diagnosis. We aimed to evaluate using the ICD-9-CM for identifying Crohn's disease (CD) in a large electronic health record (EHR) database. Methods: This is a retrospective case-control study with a 3:1 allocation of EHRs of active duty service members diagnosed with CD from 1996 to 2012. Subjects were selected by having two ICD-9-CM codes for CD during the study period. Gastroenterologists reviewed each chart and confirmed the diagnosis of CD by analysing medication history and clinical, endoscopic, histological, and radiographic exams. Results: 300 cases of CD were selected; 14 cases were discarded due to lack of data, limiting our analysis to 284 subjects. Two diagnostic codes for CD had sensitivity, specificity, and positive predictive value (PPV) of 1.0, 0.53, and 0.69, respectively, for confirmed CD. If two encounters listing CD were with a gastroenterologist, the sensitivity, specificity, and PPV was 0.76, 0.81, and 0.80, respectively. If a colonoscopy was performed within 90 days of any three encounters with a CD code, the sensitivity, specificity, and PPV was 0.51, 0.94, and 0.89, respectively. Conclusions: The poor PPV of ICD-9-CM codes in making the diagnosis of CD should be taken into consideration when interpreting results and when conducting research using such codes. Limiting these codes to those patients who have been given this diagnosis by a gastroenterologist, or to those who have had a colonoscopy near the time of diagnosis, increases the PPV.

Family history and disease outcomes in patients with Crohn's disease: A comparison between China and the United States.

AIM: To investigate the differences in family history of inflammatory bowel disease (IBD) and clinical outcomes among individuals with Crohn's disease (CD) residing in China and the United States. METHODS: We performed a survey-based cross-sectional study of participants with CD recruited from China and the United States. We compared the prevalence of IBD family history and history of ileal involvement, CD-related surgeries and IBD medications in China and the United States, adjusting for potential confounders. RESULTS: We recruited 49 participants from China and 145 from the United States. The prevalence of family history of IBD was significantly lower in China compared with the United States (China: 4.1%, United States: 39.3%). The three most commonly affected types of relatives were cousin, sibling, and parent in the United States compared with child and sibling in China. Ileal involvement (China: 63.3%, United States: 63.5%) and surgery for CD (China: 51.0%, United States: 49.7%) were nearly equivalent in the two countries. CONCLUSION: The lower prevalence of familial clustering of IBD in China may suggest that the etiology of CD is less attributed to genetic background or a family-shared environment compared with the United States. Despite the potential difference in etiology, surgery and ileal involvement were similar in the two countries. Examining the changes in family history during the continuing rise in IBD may provide further insight into the etiology of CD.

Surgeon-Level Variation in Postoperative Complications.

BACKGROUND: Variation in surgical outcomes is often attributed to patient comorbidities and the severity of underlying disease, but little is known about the extent of variation in outcomes by surgeon and the surgeon factors that are associated with quality. METHODS: Using the Maryland Health Services Cost Review Commission database, we evaluated risk-adjusted postoperative events by surgeon. Operations studied were elective laparoscopic and open colectomy procedures for colon cancer performed over a 2-year period (July 2012-September 2014). Postoperative events were defined using the Agency for Healthcare Research and Quality Patient Safety Indicators. Surgeons performing fewer than ten procedures during the study period were excluded. Logistic regression and post-estimation were used to calculate an observed-to-expected (O/E) ratio of postoperative complications for each surgeon, adjusting for patient and surgeon characteristics. RESULTS: A total of 2525 patients underwent an elective colectomy during the study period by 276 surgeons at 44 hospitals. Postoperative complications varied more by surgeon (range 0 to 30.0 %) than by hospital (range 0 to 18.2 %). Surgeon-level use of laparoscopic surgery to perform colectomy ranged from 0 to 100 %. After risk adjustment with patient factors, surgeon experience, surgeon medical school, surgeon gender, and annual surgeon colectomy volume were not associated with postoperative complications. Surgeon use of laparoscopy was the strongest predictor of lower complications (vs fourth quartile of surgeons, first quartile OR = 0.47 (0.26-0.85); second quartile OR = 0.41 (0.22-0.73); and third quartile OR = 0.84 (0.52-1.36). CONCLUSIONS: Quality metrics in health care have been measured at the hospital level, but a greater quality improvement potential exists at the surgeon level. Awareness of this variation could better inform patients undergoing elective surgery and their referring physicians.

Differences in the Prevalence of Obesity, Smoking and Alcohol in the United States Nationwide Inpatient Sample and the Behavioral Risk Factor Surveillance System.

BACKGROUND: The lack of adequate and standardized recording of leading risk factors for morbidity and mortality in medical records have downstream effects on research based on administrative databases. The measurement of healthcare is increasingly based on risk-adjusted outcomes derived from coded comorbidities in these databases. However inaccurate or haphazard assessment of risk factors for morbidity and mortality in medical record codes can have tremendous implications for quality improvement and healthcare reform. OBJECTIVE: We aimed to compare the prevalence of obesity, overweight, tobacco use and alcohol abuse of a large administrative database with a direct data collection survey. MATERIALS AND METHODS: We used the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for four leading risk factors in the United States Nationwide Inpatient Sample (NIS) to compare them with a direct survey in the Behavioral Risk Factor Surveillance System (BRFSS) in 2011. After confirming normality of the risk factors, we calculated the national and state estimates and Pearson's correlation coefficient for obesity, overweight, tobacco use and alcohol abuse between NIS and BRFSS. RESULTS: Compared with direct participant questioning in BRFSS, NIS reported substantially lower prevalence of obesity (p<0.01), overweight (p<0.01), and alcohol abuse (p<0.01), but not tobacco use (p = 0.18). The correlation between NIS and BRFSS was 0.27 for obesity (p = 0.06), 0.09 for overweight (p = 0.55), 0.62 for tobacco use (p<0.01) and 0.40 for alcohol abuse (p<0.01). CONCLUSIONS: The prevalence of obesity, overweight, tobacco smoking and alcohol abuse based on codes is not consistent with prevalence based on direct questioning. The accuracy of these important measures of health and morbidity in databases is critical for healthcare reform policies.

Better big data.

By 2018, Medicare payments will be tied to quality of care. The Centers for Medicare and Medicaid Services currently use quality-based metric for some reimbursements through their different programs. Existing and future quality metrics will rely on risk adjustment to avoid unfairly punishing those who see the sickest, highest-risk patients. Despite the limitations of the data used for risk adjustment, there are potential solutions to improve the accuracy of these codes by calibrating data by merging databases and compiling information collected for multiple reporting programs to improve accuracy. In addition, healthcare staff should be informed about the importance of risk adjustment for quality of care assessment and reimbursement. As the number of encounters tied to value-based reimbursements increases in inpatient and outpatient care, coupled with accurate data collection and utilization, the methods used for risk adjustment could be expanded to better account for differences in the care delivered in diverse settings.

Clinical Presentation and Five-Year Therapeutic Management of Very Early-Onset Inflammatory Bowel Disease in a Large North American Cohort.

OBJECTIVE: To evaluate the presentation, therapeutic management, and long-term outcome of children with very early-onset (VEO) (≤ 5 years of age) inflammatory bowel disease (IBD). STUDY DESIGN: Data were obtained from an inception cohort of 1928 children with IBD enrolled in a prospective observational registry at multiple centers in North America. RESULTS: One hundred twelve children were ≤ 5 years of age with no child enrolled at <1 year of age. Of those, 42.9% had Crohn's disease (CD), 46.4% ulcerative colitis (UC), and 10.7% had IBD-unclassified. Among the children with CD, children 1-5 years of age had more isolated colonic disease (39.6%) compared with 6- to 10-year-olds (25.3%, P = .04), and 11- to 16-year-olds (22.3%, P < .01). The change from a presenting colon-only phenotype to ileocolonic began at 6-10 years. Children 1-5 years of age with CD had milder disease activity (45.8%) at diagnosis compared with the oldest group (28%, P = .01). Five years postdiagnosis, there was no difference in disease activity among the 3 groups. However, compared with the oldest group, a greater proportion of 1- to 5-year-olds with CD were receiving corticosteroids (P < .01) and methotrexate (P < .01), and a greater proportion of 1- to 5-year-olds with UC were receiving mesalamine (P < .0001) and thiopurine immunomodulators (P < .0002). CONCLUSIONS: Children with VEO-CD are more likely to have mild disease at diagnosis and present with a colonic phenotype with change to an ileocolonic phenotype noted at 6-10 years of age. Five years after diagnosis, children with VEO-CD and VEO-UC are more likely to have been administered corticosteroids and immunomodulators despite similar disease activity in all age groups. This may suggest development of a more aggressive disease phenotype over time.
