RESUMEN

Background: There are high rates of computed tomography (CT) utilization in the emergency department (ED) for patients with inflammatory bowel disease (IBD), despite guidelines recommending judicious use. We performed a national survey to better understand perceptions and practice patterns of Canadian physicians related to CT imaging in the ED. Methods: Our survey was developed by a multistep iterative process with input from key stakeholders between 2021 and 2022. It evaluated Canadian gastroenterologists', surgeons', and emergency physicians' (1) perceived rates of IBD findings detected by CT, (2) likelihood of performing CT for specific presentations and (3) comfort in diagnosing IBD phenotypes/complications without CT. Results: A total of 208 physicians responded to our survey: median age 44 years (IQR, 37-50), 63% male, 68% academic, 44% emergency physicians, 39% gastroenterologists, and 17% surgeons. Compared with emergency physicians and surgeons, gastroenterologists more often perceived that CT would detect inflammation alone and less often IBD complications. Based on established rates in the literature, 13 (16%) gastroenterologists, 33 (40%) emergency physicians, and 21 (60%) surgeons overestimated the rates of at least one IBD complication. Although most physicians were more comfortable diagnosing inflammation compared to IBD complications without CT, gastroenterologists were significantly less likely to recommend CT imaging for non-obstructive/penetrating presentations compared with emergency physicians and surgeons with results that varied by IBD subtype. Conclusion: This national survey demonstrates differences in physician perceptions and practices regarding CT utilization in the ED and can be used as a framework for educational initiatives regarding appropriate usage of this modality.

RESUMEN

INTRODUCTION: To study digestive system cancer risks in inflammatory bowel diseases (IBD) in the biologic era. METHODS: We used population-level administrative and cancer registry data from Ontario, Canada (1994 - 2020) to compare people with IBD to matched controls (1:10 by sex and birth year) on trends in age-sex standardized cancer incidence and risk ratios of incident cancers and cancer-related deaths. RESULTS: Among 110,919 IBD and 1,109,190 controls, colorectal cancer (CRC) incidence (per 100,000 person-years) declined similarly in people with ulcerative colitis (average annual percentage change (AAPC) -1.81; 95% CI, -2.48, -1.156) and controls (AAPC -2.79; 95% CI, -3.44, -2.14), while small bowel cancer incidence rose faster in those with Crohn's disease (AAPC 9.68; 95% CI, 2.51, 17.3) than controls (AAPC 3.64; 95% CI, 1.52, 5.80). Extra-intestinal digestive cancer incidence rose faster in people with IBD (AAPC 3.27; 95% CI, 1.83, 4.73) than controls (AAPC -1.87; 95% CI, -2.33, -1.42), particularly for liver (IBD AAPC 8.48; 95% CI, 4.11, 13.1) and bile duct (IBD AAPC 7.22; 95 % CI, 3.74, 10.8) cancers. Beyond 2010, the incidences (and respective mortality rates) of colorectal (1.60; 95% CI, 1.46, 1.75), small bowel (4.10; 95% CI 3.37, 4.99), bile duct (2.33; 95% CI 1.96, 2.77) and pancreatic (1.19; 95% CI, 1.00, 1.40) cancers, were higher in people with IBD. DISCUSSION: Cancer incidence is declining for CRC and rising for other digestive cancers in people with IBD. Incidence and mortality remain higher in IBD than controls for colorectal, small bowel, bile duct and pancreatic cancers.

RESUMEN

BACKGROUND & AIMS: To date, it is unclear how environmental factors influence Crohn's disease (CD) risk and how they interact with biological processes. This study investigates the association between environmental exposures and CD risk and evaluates their association with pre-disease biomarkers. METHODS: We studied 4289 healthy first-degree relatives (FDRs) of patients with CD from the Crohn's and Colitis Canada - Genetic, Environmental, Microbial (CCC-GEM) project. Regression models identified environmental factors associated with future CD onset and their association with pre-disease biological factors, including altered intestinal permeability measured by urinary fractional excretion of lactulose to mannitol ratio (LMR); gut inflammation via fecal calprotectin (FCP) levels; and fecal microbiome composition through 16S rRNA sequencing. RESULTS: Over a 5.62-year median follow-up, 86 FDRs developed CD. Living with a dog between ages 5 and 15 (hazard ratio [HR], 0.62; 95% confidence interval [CI], 0.40-0.96; P = .034), and living with a large family size in the first year of life (HR, 0.43; 95% CI, 0.21-0.85; P = .016) were associated with decreased CD risk, whereas having a bird at the time of recruitment (HR, 2.78; 95% CI, 1.36-5.68; P = .005) was associated with an increased CD risk. Furthermore, living with a dog was associated with reduced LMR, altered relative abundance of multiple bacterial genera, and increased Chao1 diversity, whereas bird owners had higher FCP levels. Large family during participants' first year of life was associated with altered microbiota composition without affecting FCP or LMR. CONCLUSION: This study identifies environmental variables associated with CD risk. These variables were also associated with altered barrier function, subclinical inflammation, and gut microbiome composition shifts, suggesting potential roles in CD pathogenesis.

RESUMEN

Inflammatory bowel disease (IBD) patients are at increased risk of developing colorectal neoplasia (CRN). In this review, we aim to provide an up-to-date overview and future perspectives on CRN management in IBD. Advances in endoscopic surveillance and resection techniques have resulted in a shift towards endoscopic management of neoplastic lesions in place of surgery. Endoscopic treatment is recommended for all CRN if complete resection is feasible. Standard (cold snare) polypectomy, endoscopic mucosal resection and endoscopic submucosal dissection should be performed depending on lesion complexity (size, delineation, morphology, surface architecture, submucosal fibrosis/invasion) to maximize the likelihood of complete resection. If complete resection is not feasible, surgical treatment options should be discussed by a multidisciplinary team. While (sub)total and proctocolectomy play an important role in management of endoscopically unresectable CRN, partial colectomy may be considered in a subgroup of patients in endoscopic remission with limited disease extent without other CRN risk factors. High synchronous and metachronous CRN rates warrant careful mucosal visualization with shortened intervals for at least 5 years after treatment of CRN.

RESUMEN

BACKGROUND: We aimed to establish a cohort of persons with Crohn's disease (CD) enrolled from 14 Canadian centers to describe the contemporary presentation of CD in Canada. METHODS: All enrollees were at least 18 years old and underwent chart review for phenotype documentation by Montreal Classification at time of enrollment, comorbidities, inflammatory bowel disease (IBD) and other surgeries, and use IBD and other therapies. RESULTS: Of 2112 adults, 59% were female, and the mean age was 44.1 (+/-14.9SD) years. The phenotype distribution was B1 = 50.4%, B2 = 22.4%, B3 = 17.3%, and missing information = 9.9%. Perineal disease was present in 14.2%. Pertaining to disease location, 35.2% of patients had disease in L1, 16.8% in L2, 48% in L3, and 0.4% in L4. There was no difference in phenotype by gender, anxiety score, depression score. Disease duration was significantly different depending on disease behavior type (B1 = 12.2 ±â€…10.1; B2 = 19.4 ±â€…12.9; B3 = 18.9 ±â€…11.8, P < .0001). Isolated colonic disease was much less likely to be fibrostenotic or penetrating than inflammatory disease. Penetrating disease was more likely to be associated with ileocolonic location than other locations. Perineal disease was most commonly seen in persons with B3 disease behavior (24%) than other behaviors (11% B1; 20% B2 disease, P < .0001) and more likely to be seen in ileocolonic disease (L3;19%) vs L2 (17%) and L1 (11%; P < .0001). Surgery related to IBD occurred across each behavior types at the following rates: B1 = 23%, B2 = 64%, and B3 = 74%. Inflammatory bowel disease-related surgery rates by location of disease were L1 = 48%, L2 = 21%, and L3 = 51%. CONCLUSIONS: In exploring this large contemporary CD cohort we have determined that inflammatory disease is the main CD phenotype in Canada and that CD-related surgery remains very common.

RESUMEN

BACKGROUND: Patterns of health services utilization among children with inflammatory bowel disease (IBD) are important to understand as the number of children with IBD continues to increase. We compared health services utilization and surgery among children diagnosed <10 years of age (Paris classification: A1a) and between 10 and <16 years of age (A1b). METHODS: Incident cases of IBD diagnosed <16 years of age were identified using validated algorithms from deterministically linked health administrative data in 5 Canadian provinces (Alberta, Manitoba, Nova Scotia, Ontario, Quebec) to conduct a retrospective cohort study. We compared the frequency of IBD-specific outpatient visits, emergency department visits, and hospitalizations across age groups (A1a vs A1b [reference]) using negative binomial regression. The risk of surgery was compared across age groups using Cox proportional hazards models. Models were adjusted for sex, rural/urban residence location, and mean neighborhood income quintile. Province-specific estimates were pooled using random-effects meta-analysis. RESULTS: Among the 1165 (65.7% Crohn's) children with IBD included in our study, there were no age differences in the frequency of hospitalizations (rate ratio [RR], 0.88; 95% confidence interval [CI], 0.74-1.06) or outpatient visits (RR, 0.95; 95% CI, 0.78-1.16). A1a children had fewer emergency department visits (RR, 0.70; 95% CI, 0.50-0.97) and were less likely to require a Crohn's-related surgery (hazard ratio, 0.49; 95% CI, 0.26-0.92). The risk of colectomy was similar among children with ulcerative colitis in both age groups (hazard ratio, 0.71; 95% CI, 0.49-1.01). CONCLUSIONS: Patterns of health services utilization are generally similar when comparing children diagnosed across age groups.


Among 1165 children with inflammatory bowel disease, health services utilization was similar for children diagnosed <10 years of age and those diagnosed ≥10 years of age, except younger children had fewer emergency department visits and Crohn's disease­related surgeries.

RESUMEN

Purpose: The incidence of childhood-onset inflammatory bowel disease (IBD) is rising. We described variation in health services utilization and need for surgery among children with IBD between six and 60 months following IBD diagnosis across Canadian pediatric centers and evaluated the associations between care provided at diagnosis at each center and the variation in these outcomes. Patients and Methods: Using population-based deterministically-linked health administrative data from four Canadian provinces (Alberta, Manitoba, Nova Scotia, Ontario) we identified children diagnosed with IBD <16 years of age using validated algorithms. Children were assigned to a pediatric center of care using a hierarchical approach based on where they received their initial care. Outcomes included IBD-related hospitalizations, emergency department (ED) visits, and IBD-related abdominal surgery occurring between 6 and sixty months after diagnosis. Mixed-effects meta-analysis was used to pool results and examine the association between center-level care provision and outcomes. Results: We identified 3784 incident cases of pediatric IBD, of whom 2937 (77.6%) were treated at pediatric centers. Almost a third (31.4%) of children had ≥1 IBD-related hospitalization and there were 0.66 hospitalizations per person during follow-up. More than half (55.8%) of children had ≥1 ED visit and there were 1.64 ED visits per person. Between-center heterogeneity was high for both outcomes; centers where more children visited the ED at diagnosis had more IBD-related hospitalizations and more ED visits during follow-up. Between-center heterogeneity was high for intestinal resection in Crohn's disease but not colectomy in ulcerative colitis. Conclusion: There is variation in health services utilization among children with IBD and risk of undergoing intestinal resection in those with Crohn's disease, but not colectomy among children with ulcerative colitis, across Canadian pediatric tertiary-care centers. Improvements in clinical care pathways are needed to ensure all children have equitable and timely access to high quality care.

RESUMEN

INTRODUCTION: Canada has a high burden of inflammatory bowel disease (IBD). Historical trends of IBD incidence and prevalence were analyzed to forecast the Canadian burden over the next decade. METHODS: Population-based surveillance cohorts in 8 provinces derived from health administrative data assessed the national incidence (2007-2014) and prevalence (2002-2014) of IBD. Autoregressive integrated moving average models were used to forecast incidence and prevalence, stratified by age, with 95% prediction intervals (PI), to 2035. The average annual percentage change (AAPC) with 95% confidence interval (CI) was calculated for the forecasted incidence and prevalence. RESULTS: The national incidence of IBD is estimated to be 29.9 per 100,000 (95% PI 28.3-31.5) in 2023. With a stable AAPC of 0.36% (95% CI -0.05 to 0.72), the incidence of IBD is forecasted to be 31.2 per 100,000 (95% PI 28.1-34.3) in 2035. The incidence in pediatric patients (younger than 18 years) is increasing (AAPC 1.27%; 95% CI 0.82-1.67), but it is stable in adults (AAPC 0.26%; 95% CI -0.42 to 0.82). The prevalence of IBD in Canada was 843 per 100,000 (95% PI 716-735) in 2023 and is expected to steadily climb (AAPC 2.43%; 95% CI 2.32-2.54) to 1,098 per 100,000 (95% PI 1,068-1,127) by 2035. The highest prevalence is in seniors with IBD (1,174 per 100,000 in 2023; AAPC 2.78%; 95% CI 2.75-2.81). DISCUSSION: Over the next decade, the Canadian health care systems will contend with the juxtaposition of rising incidence of pediatric IBD and a rising prevalence of overall IBD driven by the aging population.

RESUMEN

BACKGROUND: Persons with inflammatory bowel diseases are at increased risk of developing colorectal cancer and require frequent colonoscopy surveillance. Guidelines recommend taking 30 to 40 non-targeted biopsies throughout the colorectum to detect "invisible" neoplasia in this setting, despite a lack of evidence supporting this practice. We sought to assess the utility of this practice through a randomized controlled trial. We first propose an internal pilot study to assess recruitment potential, protocol adherence and data capture to guide the full trial. METHODS: We have designed a multi-centre, parallel-group, non-inferiority randomized controlled trial to test the utility of non-targeted biopsies as an adjunct to colonoscopy surveillance for neoplasia detection in persons with inflammatory bowel disease involving the colorectum in routine clinical practice. Participants are randomized 1:1, stratified by study site, to either standard of care high-definition white-light colonoscopy with 32 to 40 non-targeted biopsies of non-neoplastic-appearing mucosa along with a sampling of abnormal-appearing mucosa (control group) or modified colonoscopy with targeted sampling alone (intervention group). The primary outcome for the full trial will be the proportion of persons with ≥ 1 neoplastic focus detected during colonoscopy. For the pilot phase, we will assess the feasibility of recruiting a minimum of 15% of the estimated sample size within 1 year, under identical conditions as the full trial, while maintaining ≥ 90-95% rate of protocol adherence and data capture. These participants will contribute data to the full trial. The trial is being conducted at 12 centres across Canada, with a total sample size of 1952 persons. DISCUSSIONS: The trial protocol has been approved by the ethics committees of all participating sites, and the pilot study has received funding through the Canadian Institutes of Health Research (PJT 159607). If feasibility metrics are met during the pilot phase, we will complete the full trial. The trial outcomes will contribute to update the practice guidelines in this area. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04067778.

RESUMEN

Persons with inflammatory bowel disease (IBD) affecting the colorectum (cIBD) have a 1.5- to 2-fold higher risk of developing colorectal cancer (CRC) relative to age- and sex-matched members of the general population.1 Intensive surveillance colonoscopy is recommended in this population to detect and treat early neoplastic lesions before they evolve to incurable cancers.2 Some societies advocate for widespread non-targeted ("random") biopsies throughout the colorectum to screen for "invisible" neoplastic lesions, in addition to targeted biopsies and/or resection of visible lesions.2 Despite the theoretical value of non-targeted biopsies in this setting, there are no high-quality, controlled data to support this practice. In addition to adding significant time and costs to colonoscopy screening, extensive biopsy sampling may also increase the risk of colorectal bleeding and bowel perforation, particularly in elderly patients and those receiving anticoagulant/antiplatelet therapies. With the widespread adoption of disease-modifying biologic and small molecule therapies,3 mucosal healing as a treatment end point,4 high-definition endoscopes,5 and endoscopy quality standards,6 as well as reports of very low neoplasia yield for non-targeted biopsies (0.1%-0.2% of biopsies),7 many experts have started to question the value of non-targeted biopsies as an adjunct for neoplasia surveillance in persons with cIBD.8 However, a recent large French cohort study reported that non-targeted biopsies still identify up to 20% of all neoplastic foci in persons with cIBD,9 albeit primarily in individuals with other major CRC risk factors.

RESUMEN

Inflammatory bowel disease (IBD), consisting of Crohn's disease and ulcerative colitis, is recognized across the world, though Canada has among the highest burdens of IBD in the world. The Canadian Gastro-Intestinal Epidemiology Consortium (CanGIEC) led a six-province study that demonstrated the compounding prevalence of IBD in Canada from 400 per 100,000 in 2002 to 636 per 100,000 in 2014. The prevalence in 2023 is estimated at 825 per 100,000, meaning that over 320,000 people in Canada are living with IBD. Prevalence is forecasted to rise by 2.44% per year such that 1.1% of the population, 470,000 Canadians, will live with IBD by 2035. The overall incidence of IBD in 2023 is 30 per 100,000 person-years, indicating that over 11,000 Canadians will be newly diagnosed with IBD in 2023. Incidence is forecasted to rise by 0.58% per year up to 32.1 per 100,000 by 2035. The rising incidence of IBD is propelled by pediatric-onset IBD, which is rising by 1.23% per year from 15.6 per 100,000 in 2023 to 18.0 per 100,000 in 2035. In contrast, incidence rates among adults and seniors are relatively stable. Understanding the determinates of IBD has expanded through prospective cohort studies such as the Crohn's and Colitis Canada Genetic, Environmental, Microbial (CCC-GEM) project. Consensus recommendations towards diet, lifestyle, behavioural and environmental modifications have been proposed by international organizations with the goal of optimizing disease control and ultimately preventing the development of IBD. Despite these efforts, Canadian healthcare systems will need to prepare for the rising number of people living with IBD.

RESUMEN

Healthcare utilization among people living with inflammatory bowel disease (IBD) in Canada has shifted from inpatient management to outpatient management; fewer people with IBD are admitted to hospitals or undergo surgery, but outpatient visits have become more frequent. Although the frequency of emergency department (ED) visits among adults and seniors with IBD decreased, the frequency of ED visits among children with IBD increased. Additionally, there is variation in the utilization of IBD health services within and between provinces and across ethnocultural and sociodemographic groups. For example, First Nations individuals with IBD are more likely to be hospitalized than the general IBD population. South Asian children with Crohn's disease are hospitalized more often than their Caucasian peers at diagnosis, but not during follow-up. Immigrants to Canada who develop IBD have higher health services utilization, but a lower risk of surgery compared to individuals born in Canada. The total direct healthcare costs of IBD, including the cost of hospitalizations, ED visits, outpatient visits, endoscopy, cross-sectional imaging, and medications are rising rapidly. The direct health system and medication costs of IBD in Canada are estimated to be $3.33 billion in 2023, potentially ranging from $2.19 billion to $4.47 billion. This is an increase from an estimated $1.28 billion in 2018, likely due to sharp increases in the use of biologic therapy over the past two decades. In 2017, 50% of total direct healthcare costs can be attributed to biologic therapies; the proportion of total direct healthcare costs attributed to biologic therapies today is likely even greater.

RESUMEN

The COVID-19 pandemic had a monumental impact on the inflammatory bowel disease (IBD) community. At the beginning of the pandemic, knowledge on the effect of SARS-CoV-2 on IBD was lacking, especially in those with medication-suppressed immune systems. Throughout the pandemic, scientific literature exponentially expanded, resulting in clinical guidance and vaccine recommendations for individuals with IBD. Crohn's and Colitis Canada established the COVID-19 and IBD Taskforce to process and communicate rapidly transforming knowledge into guidance for individuals with IBD and their caregivers, healthcare providers, and policy makers. Recommendations at the onset of the pandemic were based on conjecture from experience of prior viruses, with a precautionary principle in mind. We now know that the risk of acquiring COVID-19 in those with IBD is the same as the general population. As with healthy populations, advanced age and comorbidities increase the risk for severe COVID-19. Individuals with IBD who are actively flaring and/or who require high doses of prednisone are susceptible to severe COVID-19 outcomes. Consequently, sustaining maintenance therapies (e.g., biologics) is recommended. A three-dose mRNA COVID-19 vaccine regimen in those with IBD produces a robust antibody response with a similar adverse event profile as the general population. Breakthrough infections following vaccine have been observed, particularly as the virus continues to evolve, which supports receiving a bivalent vaccine booster. Limited data exist on the impact of IBD and its therapies on long-term outcomes following COVID-19. Ongoing research is necessary to address new concerns manifesting in those with IBD throughout the evolving pandemic.

RESUMEN

People living with inflammatory bowel disease (IBD) and their caregivers are faced with indirect and out-of-pocket costs that they would not otherwise experience. These costs impact one's ability to contribute to the economy to their fullest potential. The indirect costs of IBD in Canada are estimated to be at least $1.51 billion in 2023 and include costs associated with lost productivity resulting from a combination of missed work (absenteeism), decreased workplace productivity (presenteeism), unemployment, premature mortality, and caregiving costs. Unemployment is the largest contributor to indirect costs ($1.14 billion), followed by costs of absenteeism and presenteeism ($285 million). Caregiving costs for children with IBD are estimated to be nearly $58 million. Canadians with IBD also pay $536 million every year for care that is not covered by universal or supplemental private health insurance; this includes allied healthcare (e.g., care provided by psychologists), medication, and other supportive therapy. Combined, the indirect and out-of-pocket costs of IBD in Canada are estimated at more than $2 billion CAD in 2023. This is substantially higher than the estimate of $1.29 billion in Crohn's and Colitis Canada's 2018 Impact of IBD report with differences attributable to a combination of rising prevalence, inflation, and the addition of presenteeism and caregiving costs to the total indirect costs.

RESUMEN

Sex (the physical and physiologic effects resulting from having specific combinations of sex chromosomes) and gender (sex-associated behaviours, expectations, identities, and roles) significantly affect the course of inflammatory bowel disease (IBD) and the experience of living with IBD. Sex-influenced physiologic states, like puberty, the menstrual cycle, pregnancy, and andropause/menopause may also impact and be impacted by IBD. While neither Crohn's disease nor ulcerative colitis is commonly considered sex-determined illnesses, the relative incidence of Crohn's disease and ulcerative colitis between males and females varies over the life cycle. In terms of gender, women tend to use healthcare resources at slightly higher rates than men and are more likely to have fragmented care. Women are more commonly prescribed opioid medications and are less likely than men to undergo colectomy. Women tend to report lower quality of life and have higher indirect costs due to higher rates of disability. Women are also more likely to take on caregiver roles for children with IBD. Women with IBD are more commonly burdened with adverse mental health concerns and having poor mental health has a more profound impact on women than men. Pregnant people with active IBD have higher rates of adverse outcomes in pregnancy, made worse in regions with poor access to IBD specialist care. The majority of individuals with IBD in Canada do not have access to a pregnancy-in-IBD specialist; access to this type of care has been shown to allay fears and increase knowledge among pregnant people with IBD.

RESUMEN

The burden of inflammatory bowel disease (IBD) (i.e., associated direct and indirect costs, prevalence of disease, personal impact to the individual and to caregivers) continues to increase in Canada. The prevalence of IBD has increased since Crohn's and Colitis Canada's 2018 Impact of IBD report from an estimated 270,000 Canadians living with IBD in 2018 to an estimated 322,600 Canadians living with IBD today in 2023. Consequently, associated costs of IBD have also dramatically increased from an estimated $2.57 billion in 2018 to an estimated $5.38 billion in 2023; this increase is due to multiple factors including increased prevalence of disease, inflation, and additional identified factors (e.g., presenteeism, costs of childcare). Beyond the economic impact of IBD, these diseases have a significant impact on people living with the disease and their caregivers, including different presentations of disease, different commonly associated extra-intestinal manifestations or comorbid conditions, and different barriers to accessing care. In this supplementary issue, we review: Evolving trends in the epidemiology of IBD; updated estimates of indirect and direct costs (including out-of-pocket costs) associated with IBD; information specific to IBD in children, adolescents, and seniors; issues related to IBD pertaining to sex and gender; information specific to risks associated with COVID-19 and cancer related to IBD; an overview of current treatments for IBD; and evolving care models, including access to care.

RESUMEN

Rising compounding prevalence of inflammatory bowel disease (IBD) (Kaplan GG, Windsor JW. The four epidemiological stages in the global evolution of inflammatory bowel disease. Nat Rev Gastroenterol Hepatol. 2021;18:56-66.) and pandemic-exacerbated health system resource limitations have resulted in significant variability in access to high-quality, evidence-based, person-centered specialty care for Canadians living with IBD. Individuals with IBD have identified long wait times, gaps in biopsychosocial care, treatment and travel expenses, and geographic and provider variation in IBD specialty care and knowledge as some of the key barriers to access. Care delivered within integrated models of care (IMC) has shown promise related to impact on disease-related outcomes and quality of life. However, access to these models is limited within the Canadian healthcare systems and much remains to be learned about the most appropriate IMC team composition and roles. Although eHealth technologies have been leveraged to overcome some access challenges since COVID-19, more research is needed to understand how best to integrate eHealth modalities (i.e., video or telephone visits) into routine IBD care. Many individuals with IBD are satisfied with these eHealth modalities. However, not all disease assessment and monitoring can be achieved through virtual modalities. The need for access to person-centered, objective disease monitoring strategies, inclusive of point of care intestinal ultrasound, is more pressing than ever given pandemic-exacerbated restrictions in access to endoscopy and cross-sectional imaging. Supporting learning healthcare systems for IBD and research relating to the strategic use of innovative and integrative implementation strategies for evidence-based IBD care interventions are greatly needed. Data derived from this research will be essential to appropriately allocating scarce resources aimed at improving person-centred access to cost-effective IBD care.

RESUMEN

Rates of inflammatory bowel disease (IBD) in Canadian children and adolescents are among the highest in the world, and the incidence is rising most rapidly in children under five years of age. These young children may have either a typical form of IBD with multi-factorial aetiology, or they may have a monogenic form. Despite the growing number of children in Canada living with this important chronic disease, there are few available medical therapies approved by Health Canada due to the omission of children from most clinical trials of newly developed biologics. As a result, off-label use of medications is common, and physicians have learned to use existing therapies more effectively. In addition, most Canadian children are treated in multidisciplinary, specialty clinics by physicians with extra training or experience in IBD, as well as specialist nurses, dietitians, mental health care providers and other allied health professionals. This specialized clinic approach has facilitated cutting edge research, led by Canadian clinicians and scientists, to understand the causes of IBD, the optimal use of therapies, and the best ways to treat children from a biopsychosocial perspective. Canadians are engaged in work to understand the monogenic causes of IBD; the interaction between genes, the environment, and the microbiome; and how to address the mental health concerns and medical needs of adolescents and young adults transitioning from paediatric to adult care.

RESUMEN

Psychiatric disorders are 1.5 to 2 times more prevalent in persons with inflammatory bowel disease (IBD) than in the general population, with pooled prevalence estimates of 21% for clinical anxiety and 15% for depression. Rates are even higher when considering mental health symptoms, as nearly one-third of persons with IBD experience elevated anxiety symptoms and one-quarter experience depression symptoms. Rates of these symptoms were much higher during periods of disease activity, more common in women than men, and more common in Crohn's disease than ulcerative colitis. There is robust evidence of the detrimental effects of comorbid depression and anxiety on the subsequent course of IBD based on longitudinal studies tracking outcomes over time. However, psychiatric disorders and IBD have bidirectional effects, with each affecting risk of the other. Elevated mental health concerns have been consistently associated with greater healthcare utilization and costs related to IBD. There is some signal that low resilience in adolescence could be a risk factor for developing IBD and that enhancing resilience may improve mental health and intestinal disease outcomes in IBD. Psychological therapies used to treat anxiety and depression occurring in the context of IBD have been shown to significantly improve the quality of life for persons with IBD and reduce anxiety and depression. There is less evidence in regard to the impact of psychotropic medications on mental health or disease outcomes in persons with IBD. There is consensus, however, that mental health must be addressed as part of comprehensive IBD care for children and adults.
