1. Optimizing tissue acquisition to improve the diagnostic yield of endoscopic ultrasound-guided fine needle biopsy of solid masses: a quality improvement initiative.
PMID:日期:2026-06-18A chart audit (pre-intervention, PRE) of endoscopic ultrasound (EUS)-fine needle biopsy (FNB) of solid masses identified a diagnostic yield of 75%. To improve diagnostic yield, a quality improvement intervention targeting tissue procurement and processing was developed and trialed (post-intervention, POST). Increase needle passes to ≥3/mass, limit the personnel preparing cytology slides, and replace saline with formalin for cell block preparation. A POST chart audit was undertaken for solid mass EUS-FNB from January 2024-December 2024, with quarterly reviews. Only a definite diagnosis was used to calculate diagnostic yield. 241 patients underwent 262 EUS-FNBs. Diagnostic yield was 81% in POST vs. 75% in PRE ( = ns). Single passes decreased to 14% in POST vs. 20% in PRE ( = ns), with similar diagnostic yield (57% vs. 56%, respectively). Number of ≥3 passes increased significantly (47% POST vs. 12% PRE, < .0001). In POST, 86% of single passes were performed in the first half vs. 14% in the second (= .012). Only 25% of ≥3 passes were performed in the first half vs. 75% in the second (= .06). Diagnostic yield improved significantly between the first and second halves (72% vs. 90%, < .0001). Replacing saline with formalin for cell block improved diagnostic yield (57% vs. 75%, = .062). Limiting the personnel making slides from 25 nurses (PRE) to 3 endoscopists (POST) had no impact on diagnostic yield. Critical practice assessment, regular audit, and continued reinforcement led to a significant improvement in EUS-FNB diagnostic yield to 90% by increasing the number of needle passes to ≥3/mass.

2. Optimism and mindfulness are associated with decreased abdominal pain among adolescents with inflammatory bowel disease.
PMID:日期:2026-05-30Inflammatory bowel disease (IBD) is a chronic relapsing and remitting disease, frequently causing abdominal pain. The gut-brain axis provides an extensive framework to understand the relationship between IBD and psychological well-being. Accumulating evidence indicates that prolonged psychological stress may worsen IBD symptoms and recurrence. Resilience factors (eg, optimism, self-efficacy, mindfulness) are associated with improved outcomes in other populations with recurrent pain; however, it has not been investigated in adolescent IBD populations. To examine the association between resilience factors and abdominal pain intensity in adolescents with IBD. A cross-sectional study of 70 adolescents (aged 12-17 years) with IBD (51% male, 47% in clinical remission) was conducted. Multivariable hurdle models were used to predict the presence and degree of pain. In conditional models, all variables were adjusted for age and sex. In all models, disease activity and optimism were significant predictors of pain presence (OR 0.92 [95% CI, 0.85-0.99]). In unconditional models, sex was associated with degree of pain. Predicted pain intensity was 1.37 times greater for females than males. Sex was not significantly associated with pain presence. Increased clinical disease activity, lower optimism, and lower mindfulness scores were associated with pain presence in adolescents with IBD. Our findings support an association between clinical disease activity, optimism, mindfulness, and pain. These results highlight the potential benefits of incorporating resilience-based pain management strategies alongside clinical disease assessment and treatment for adolescents with IBD.

3. Exploring endoscopy sedation experiences in young adults with pediatric-onset inflammatory bowel disease after transfer to adult gastroenterology care.
PMID:日期:2026-05-25Sedation practices differ between pediatric and adult endoscopy units and may shape how patients with inflammatory bowel disease (IBD) experience procedures after transfer to adult care. To evaluate endoscopy-related experiences in pediatric and adult settings among young adults with pediatric-onset IBD following transfer to adult gastroenterology care. We conducted a single-centre, cross-sectional survey at an academic institution (June 2024 to February 2025) among young adults (18-25 years) with pediatric-onset IBD who underwent endoscopy in both pediatric and adult settings. Participants reported on procedure-related satisfaction, pain, discomfort, anxiety, and preparedness. Regression analyses identified predictors of these outcomes, and free-text responses were analyzed using qualitative content analysis. Among 97 participants (72% female; median diagnosis age 14 years), deep sedation was more common in pediatric (95%) than adult endoscopy (57%). Paired Wilcoxon signed-rank tests showed adult endoscopy was associated with lower satisfaction with sedation ( = .0001), greater pain ( = .0007), and discomfort ( = .0002). There were no significant differences in anxiety ( = .47) or satisfaction with preparedness for adult care ( = .47). Older age at diagnosis was associated with lower odds of reporting pain (aOR 0.19, 95% CI 0.05-0.70) and anxiety (aOR 0.20, 95% CI 0.05-0.72) during adult endoscopy. Qualitative themes highlighted limited communication and perceived lack of empathy as barriers, while education and provider compassion facilitated positive experiences. Endoscopy experiences differ between pediatric and adult care. Improving communication, patient education, and shared decision-making around sedation may improve endoscopy experiences in adult settings.

4. Nationalization of clinical care pathways for inflammatory bowel disease management in Canada.
PMID:日期:2026-05-19Inflammatory Bowel Diseases (IBD) are challenging conditions to manage due to the heterogeneity of the disease, diverse treatment options, and nuances of care over a range of ages. Clinical care pathways (CCPs) developed by experts enable health care providers (HCPs) to deliver standardized, high-quality, evidence-based care. In order to remain useful and valuable, these pathways need to evolve alongside changing treatment recommendations. Standardizing IBD care is a priority of Crohn's Colitis Canada's Promoting Access and Care through Centres of Excellence (PACE) network. To describe the process of nationalizing IBD CCP's, including development, standardization, maintenance, and dissemination. This project was based on a previously developed structured framework for review and maintenance. The CCP team consisted of a leadership group, advisory council and a working group with diverse representation from the country and areas of expertise. The work was tracked with a database with coordination completed by staff of the national organization. The nationalization process lasted 14 months, with input from 23 HCPs from 14 academic and community institutions across Canada. Sixteen CCPs for IBD care were developed and approved by the CCP team. Challenges encountered included outdated guidelines, differing clinical opinions, and busy clinical schedules of the team members. Translation into French is complete. Support of Crohn's and Colitis Canada was invaluable. Despite anticipated challenges, 16 CCPs received approval from the advisory council and are publicly available to HCPs across Canada. Our approach to this undertaking and the lessons learned may be valuable for experts undertaking similar projects for patients with chronic diseases.

5. Temporal trends in depression-related hospitalizations and suicide among patients with inflammatory bowel disease.
PMID:日期:2026-05-14Individuals with inflammatory bowel disease (IBD) are at higher risk of depression. However, data on depression-related hospitalizations and suicide death remain limited. This population-based study used administrative data to identify annual prevalent cohorts of individuals with IBD and matched controls between fiscal years 2005/2006 to 2021/2022. The primary outcomes were hospitalization for depression and suicide death. An IBD incident cohort was used to estimate the 1-, 3-, and 5-year cumulative incidence with 95% confidence intervals (CIs). Temporal trends were evaluated by calculating the average annual percent change (AAPC) using Poisson or negative binomial regression models. Conditional logistic regression estimated the odds ratio (OR) for depression-related hospitalizations between individuals with and without IBD. Individuals with IBD had higher odds of depression-related hospitalization than matched controls (OR = 1.52; 95% CI, 1.38, 1.67). Over time, depression-related hospitalizations decreased in those with IBD (AAPC: -3.38%; 95% CI, -4.72, -2.03), driven by Crohn's disease (AAPC: -4.76; 95% CI, -7.06, -2.39), whereas rates were stable in ulcerative colitis (AAPC: -1.71%; 95% CI, -4.46, 1.11). Hospitalization rates for depression in IBD declined in adults but were stable for pediatric patients (2.56%; 95% CI, -7.17, 13.30). Suicide deaths occurred in 0.21% (95% CI, 0.17, 0.25) of those with IBD and were stable over time (AAPC: -0.99%; 95% CI, -2.44, 0.48). The 1-, 3-, and 5-year cumulative incidence of depression-related hospitalization in the IBD incident cohort was 0.16% (95% CI, 0.12, 0.22), 0.41% (95% CI, 0.33, 0.50), and 0.63% (95% CI, 0.52, 0.75), respectively. Depression-related hospitalizations declined among individuals with IBD, particularly those with Crohn's disease, whereas suicide rates were stable.

6. Human-machine interaction in optical polyp diagnosis: decision-making after CADx polyp diagnosis.
PMID:日期:2026-04-29Artificial intelligence (AI)-based computer-aided diagnosis (CADx) systems are increasingly used to classify colorectal polyps during colonoscopy, but their impact depends on how endoscopists interpret AI predictions. This study aimed to evaluate endoscopists' decision-making after reviewing CADx outputs, using histopathology diagnosis as ground truth. We performed a secondary analysis of a prospective study (NCT06822816) conducted at our centre between 2022 and 2025. All patients and polyps ≤10 mm with documented CADx output and endoscopist diagnosis were included. Endoscopists either accepted CADx classifications (neoplastic vs hyperplastic) or provided alternatives. Our primary outcome was the accuracy of accepted CADx diagnoses; secondary outcomes assessed reclassification patterns after CADx output rejection. Our cohort included 754 polyps <10 mm from 367 patients. Accepted CADx diagnoses were correct for 89.1% of neoplastic and 68.7% of hyperplastic CADx predictions. Endoscopists accepted incorrect CADx classifications more frequently when these were neoplastic compared to hyperplastic (64.9% vs 26.5%). Upon rejecting correct CADx neoplastic predictions, endoscopists misclassified 23.4% as sessile serrated lesions (SSLs). Similarly, 29.5% of rejected correct CADx hyperplastic predictions were incorrectly reassigned as SSLs. Endoscopists exhibit a diagnostic bias toward neoplasia, particularly misclassifying hyperplastic polyps as SSLs. While this may enhance safety, it may risk unnecessary surveillance colonoscopies and increase costs.

7. Perception of care in immigrant and nonimmigrant persons with inflammatory bowel disease: a survey-based study.
PMID:日期:2026-04-17Immigrants are at a heightened risk of developing inflammatory bowel disease (IBD) after relocating, and their interactions with the healthcare system differ from those of nonimmigrants. This study aimed to explore the challenges and perspectives of immigrants living with IBD regarding their healthcare. We recruited persons aged 18 or over with IBD, including those with and without an immigration history, to complete an anonymous online survey. Descriptive statistics were presented as frequencies, and cross-group comparisons were performed using the Chi-square test. We included 75 immigrants and 150 nonimmigrants with similar baseline demographics, with many indicating poorly controlled IBD. Immigrants were more likely to report no access to formal translation services during their appointments (24 [32%] vs 6 [8%]), despite many not speaking the same language as their gastroenterologist (31 [41.3%] vs 3 [2%]). Immigrants were more often unable to miss work for healthcare appointments (24 [32%] vs 17 [11.3%]). Many were diagnosed after immigration (58 [77.3%]). Despite this, 29 [38.7%] contacted physicians in their home countries and purchased medications from their countries of origin (8 [10.7%]). Most immigrants expressed concerns that "Western" foods in their current country of residence contributed to their flares (44 [58.7%]) compared to only 11 [14.7%] who were concerned about foods from their home country. Immigrants encounter significant obstacles in accessing healthcare, including communication, financial barriers, and cultural factors such as food preferences, which hinder their ability to receive the care they need.

9. Multicomponent audit and feedback for colonoscopy quality improvement among potentially lower-performing endoscopists.
PMID:日期:2026-03-27Multicomponent audit and feedback (A&F) initiatives pair performance reports with education to improve quality. A&F is most effective for those with greatest room for improvement, but effects depend on engagement with A&F. The study objectives were to (1) determine the proportion of potentially lower-performing endoscopists who participated in a voluntary multicomponent A&F initiative, (2) identify barriers and facilitators to endoscopist participation, and (3) describe the actions taken by endoscopists after exposure to this initiative. We conducted an explanatory sequential mixed methods study. All potentially lower-performing endoscopists practicing in Ontario in 2015 were invited to participate in a voluntary multicomponent A&F initiative; participation rates were tracked. Subsequently, endoscopists were invited to an interview to share their experience with the A&F initiative. Interviews were transcribed. Data were analyzed using directed and conventional content analyses. We identified 121 potentially lower-performing endoscopists among the 885 practicing in Ontario in 2015. Only 25 endoscopists (20.7%) participated in the A&F initiative. Eleven of 121 endoscopists completed the interview. Interviewees discussed 18 facilitators and 11 barriers to participation in the A&F initiative. Some interviewees took steps to improve their colonoscopy quality, changed documentation practices to improve the accuracy of future A&F reports, or adopted potentially inappropriate documentation or patient care practices to look better on future A&F reports. The low participation rate, the range of drivers of endoscopist participation, and the intended and unintended effects identified suggest that A&F initiatives are complex interventions requiring careful design and evaluation.

10. Qualitative evaluation of a video-based tool to support informed consent in colonoscopy.
PMID:日期:2026-03-09Endoscopy unit efficiency is critical to provide timely and quality care, despite limited resources. In previous work, obtaining informed consent was the most common documented cause of delay. We developed a 4-minute animated video to facilitate the consent process, describing colonoscopy, its purpose, and potential risks and benefits. In this study, we aim to assess (1) the ability of the video to support the informed consent process and (2) the extent to which the video is attractive, clear, acceptable, actionable and usable, from the perspective of the audience. Using a critical case sample design with maximum variation, 12 participants completed pre- and postcolonoscopy 1:1 semistructured interviews after viewing the video. Questions evaluated whether key components of informed consent were conveyed and assessed the video using principles of learner verification (attractiveness, usability, comprehension, self-efficacy, acceptability). Interviews were recorded and transcribed. Data were coded inductively and deductively. Regarding informed consent, most participants understood the purpose and nature of a colonoscopy, but alternatives and participants' right to refuse were less effectively communicated. As a communication tool, the animations engaged participants and aided comprehension of complex material. The language was accessible; however, some participants found the video too fast and the font too small. Most participants found the video acceptable and characters relatable. Some identified information gaps included sedation level and procedure duration. The video-based tool can supplement standard approaches to informed consent for patients undergoing colonoscopy. Findings have informed revisions to the video and will guide its evaluation and implementation into clinical practice. Future research should assess its impact on endoscopy unit efficiency.
