Patient Preferences for Ulcerative Colitis Treatment in the Middle East Region: A Discrete-Choice Experiment.

Background and Aims: Treatments for ulcerative colitis (UC) differ in safety, efficacy, and route of administration; patient preferences for treatment attributes should be considered in treatment decisions. No study to date has explored patient preferences for moderate-to-severe UC treatment in Middle Eastern countries. Methods: A discrete-choice experiment aimed to quantify treatment preferences in patients with moderate-to-severe UC in 5 Middle Eastern countries (Saudi Arabia, Kuwait, Jordan, the United Arab Emirates, and Lebanon). Respondents chose between experimentally designed profiles for hypothetical UC treatments with varying efficacy (time until UC symptoms improve and chance of UC symptom control after 1 year), side effects (annual risk of serious infection, 5-year risk of malignancy), mode and frequency of administration, and need for occasional steroid use. A random-parameters logit model was used to estimate preference weights for these attributes, from which conditional relative importance estimates and maximum acceptable increases in risks of serious infection and malignancy were derived. Results: Among 365 adults with moderate-to-severe UC who completed the survey (mean age, 36 years; 50% female), 5-year risk of malignancy and symptom control after 1 year had the greatest conditional relative importance. Respondents were generally willing to accept statistically significant increases in annual risk of serious infection and 5-year risk of malignancy in exchange for better efficacy, changes in mode of administration and dosing schedule, and avoiding occasional steroid use. Conclusion: Of the attributes evaluated, individuals with UC in Middle Eastern countries most value avoiding 5-year risk of malignancy and a higher probability of symptom control, on average.

Development and validation of metric-based-training to proficiency simulation curriculum for upper gastrointestinal endoscopy using a novel assessment checklist.

BACKGROUND/AIMS: : This study aimed to design a structured simulation training curriculum for upper endoscopy and validate a new assessment checklist. MATERIALS AND METHODS: A proficiency-based progression stepwise curriculum was developed consisting of didactic, technical and non-technical components using a virtual reality simulator (VRS). It focused on: scope navigation, anatomical landmarks identification, mucosal inspection, retro-flexion, pathology identification, and targeting biopsy. A total of 5 experienced and 10 novice endoscopists were recruited. All participants performed each of the selected modules twice, and mean and median performance were compared between the two groups. Novices pre-set level of proficiency was set as 2 standard deviations below the mean of experts. Performance was assessed using multiple-choice questions for knowledge, while validated simulator parameters incorporated into a novel checklist; Simulation Endoscopic Skill Assessment Score (SESAS) were used for technical skills. RESULTS: : The following VRS outcome measures have shown expert vs novice baseline discriminative ability: total procedure time, number of attempts for esophageal intubation and time in red-out. All novice trainees achieved the preset level of proficiency by the end of training. There were no statistically significant differences between experts' and trainees' rate of complications, landmarks identification and patient discomfort. SESAS checklist showed high degree of agreement with the VRS metrices (kappa = 0.83) and the previously validated direct observation of procedural skills tool (kappa = 0.90). CONCLUSION: : The Fundamentals of Gastrointestinal Endoscopy simulation training curriculum and its SESAS global assessment tool have been primarily validated and can serve as a valuable addition to the gastroenterology fellowship programs. Follow up study of trainee performance in workplaces is recommended for consequences validation.

Consensus Statement by an Expert Panel on the Diagnosis and Management of Iron Deficiency Anemia in the Gulf Cooperation Council Countries.

BACKGROUND: Iron deficiency (ID) and ID anemia (IDA) are common in the member states of the Gulf Cooperation Council (GCC). The unique genetic and lifestyle factors of the patient population in the region have necessitated the development of recommendations to help educate health-care professionals on appropriate diagnosis and management of ID/IDA. METHODS: A panel of regional experts, including gastroenterologists and hematologists with expertise in the treatment of IDA, was convened to develop regional practice recommendations for ID/IDA. After reviewing the regional and international literature, the expert panel developed consensus recommendations for screening, diagnosis, and treatment of patients with IDA in the GCC region. RESULTS: The recommendations proposed were customized to the patient population keeping in view the increasingly recognized burden of coeliac disease, high fertility and obesity rates, high prevalence of alpha- and beta-thalassemia traits, and poor tolerance and low treatment compliance with oral iron therapy. CONCLUSIONS: This consensus statement proposes recommendations for screening, diagnosis, and treatment of IDA in the GCC region.

Greater prevalence of comorbidities with increasing age: Cross-sectional analysis of chronic hepatitis B patients in Saudi Arabia.

BACKGROUND/AIMS: Middle Eastern countries, including Saudi Arabia to some extent, are endemic for chronic hepatitis B (CHB) infection which could be associated with high mortality and comorbidities risk. However, limited data characterizing this CHB population exists. Our aim was to characterize and compare CHB patients in 2015 with those in 2010 and 2012 in Saudi Arabia. PATIENTS AND METHODS: We conducted and compared three cross-sectional analyses of adult patients with CHB defined as either positive hepatitis B surface antigen or documented CHB history in 2010, 2012, and 2015. Data were accessed from the multicenter Systematic Observatory Liver Disease Registry (SOLID). RESULTS: A total of 765 CHB patients were identified in 2010 (n = 274), 2012 (n = 256), and 2015 (n = 235). Median age was significantly higher in 2015 (47 years) compared to 2010 and 2012 (42 years;P < 0.05). The proportions of patients with hepatocellular carcinoma (range 1-12%) and cirrhosis (range 5-23%) were significantly higher in 2015 compared to 2010 and 2012 (P < 0.05). Compared to 2010, patients in 2015 had significantly (P < 0.05) higher prevalence of coronary artery disease (10% vs. 4%) and hyperbilirubinemia (18% vs. 9%). Although not significant, there was a numerical increase in 2015 in chronic kidney disease (9% vs. 7% in 2010;P= 0.559) and hepatic steatosis (32% vs. 25% in 2010;P= 0.074). Significantly more patients in 2015 (P < 0.05) were treatment experienced (23% vs. 5% in 2010/2012) and switched treatment (17% vs. 1-2% in 2010/2012). CONCLUSIONS: Between 2010 and 2015, the CHB population in Saudi Arabia had significantly aged and was more likely to develop liver disease sequelae and other comorbidities.

National Guidelines for Colorectal Cancer Screening in Saudi Arabia with strength of recommendations and quality of evidence.

BACKGROUND: Colorectal cancer is the most common cancer among Saudi men and the third commonest among Saudi women. Given the predominance of colorectal cancer compared with other cancers in Saudi Arabia, context-specific guidelines are needed for screening. METHODS: Experts from the Saudi Society of Colon and Rectal Surgery, Saudi Gastroenterology Association, Saudi Oncology Society, Saudi Chapter of Enterostomal Therapy, Family Medicine and Department of Public Health at the Saudi Arabian Ministry of Health and a patient advocate was assembled by the Saudi Centre for Evidence-Based Healthcare, a subsidiary of the Saudi Arabian Ministry of Health. The panel collaborated with a methodological team from McMaster University, Canada to develop national guidelines for colorectal cancer screening. After identifying key questions, the panel conducted a systematic review of all reports on the utility of screening, the cost of screening for colorectal cancer in Saudi Arabia and on the values and preferences of Saudi patients. Meta- analyses, when appropriate, were performed to generate pooled estimates of effect. Using the GRADE approach, the panel used the evidence-to-decision (EtD) framework to assess all domains important in determining the strength and direction of the recommendations (benefits and harms, values and preferences, resource implications, equity, acceptability, and feasibility). Judgments related to the EtD domains were resolved through consensus or voting, if consensus was not reached. The final recommendations were developed during a two-day meeting held in Riyadh, Saudi Arabia in March 2015. Conflicts of interests among the panel members were handled according to the World Health Organization rules. LIMITATIONS: There is lack of national data on the incidence of adenomatous polyps or the age groups in which the incidence surges. There were no national clinical trials assessing the effectiveness of the different modalities of screening for colorectal cancer and their impact on mortality. CONCLUSION: The panel recommends screening for colorectal cancer in Saudi Arabia in asymptomatic Saudi patients at average risk of colorectal cancer. An infrastructure should be built to achieve that goal.

Hepatic granuloma: decreasing trend in a high-incidence area.

BACKGROUND: Hepatic granuloma (HG) has a high reported incidence in Saudi Arabia (14.6%). We aimed to identify the incidence of HG in our centres and review its presenting features and underlying aetiology. METHODS: A total of 5531 liver biopsies were screened through a computer database over 13 years. Sixty-six (1.2%) patients fulfilled our inclusion criteria. The patients were then divided into three groups according to the aetiology. Group 1, tuberculosis (n=26); Group 2, viral hepatitis B and C (n=11); and Group 3, idiopathic (n=9). The demographical data and the clinical and biochemical features of all the groups were analysed. RESULTS: Infections comprised of 72.2% of HG. The incidence of tuberculosis was 42.6%, viral hepatitis 16.3% and idiopathic 14.8%. Fever (47.5%), weight loss (42.6%) and fatigue (45.9%) were commonly found symptoms. Fever and weight loss were significantly more frequently presenting symptoms in Group 1 than in Groups 2 and 3 (P=0.0002, 0.04, 0.001 and 0.02 respectively). The mean bilirubin levels in Group 1 were significantly lower than in Groups 2 and 3 (P=0.04 and 0.03 respectively). The mean albumin levels were significantly lower in Group 3 compared with Group 2 (P=0.002), and Group 1 had lower levels compared with Group 2 (P=0.018). CONCLUSION: The incidence of HG is much lower than reported previously from this region. Tuberculosis and viral hepatitis are the most common causes and, contrary to previous reports, schistosomiasis is rare. Fever and weight loss distinguished tuberculous HG.
