The 2023 Impact of Inflammatory Bowel Disease in Canada: Direct Health System and Medication Costs.

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.

The 2023 Impact of Inflammatory Bowel Disease in Canada: Indirect (Individual and Societal) and Direct Out-of-Pocket Costs.

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.

The 2023 Impact of Inflammatory Bowel Disease in Canada: The Influence of Sex and Gender on Canadians Living With Inflammatory Bowel Disease.

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.

Optimizing maternal and neonatal outcomes through tight control management of inflammatory bowel disease during pregnancy: a pilot feasibility study.

A home point-of care FCP test (IBDoc) and a self-reported clinical disease activity program (IBD Dashboard) may improve routine monitoring of IBD activity during pregnancy. We aimed to evaluate the feasibility of tight control management using remote monitoring in pregnant patients with IBD. Pregnant patients (< 20 weeks) with IBD were prospectively enrolled from Mount Sinai Hospital between 2019 and 2020. Patients completed the IBDoc and IBD Dashboard at three core time points. Disease activity was measured clinically using the Harvey-Bradshaw Index (mHBI) for CD and partial Mayo (pMayo) for UC, or objectively using FCP. A feasibility questionnaire was completed in the third trimester. Seventy-seven percent of patients (24 of 31) completed the IBDoc and IBD Dashboard at all core time points. Twenty-four patients completed the feasibility questionnaires. All survey respondents strongly preferred using the IBDoc over standard lab-based testing and would use the home kit in the future. Exploratory analysis identified discordance rates of more than 50% between clinical and objective disease activity. Tight control management using remote monitoring may be feasible among pregnant patients with IBD. A combination of both clinical scores and objective disease markers may better predict disease activity.

Predictors and Hospital Outcomes in Pregnant Patients Undergoing Extracorporeal Membrane Oxygenation: A Nationwide Study.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is increasingly used in patients with severe cardiorespiratory collapse. Although prior large database reviews of ECMO use in the peripartum population exist, they do not stratify by ECMO indication nor do they include obstetric conditions such as preeclampsia. Our objective was to characterize the incidence, indication-associated mortality, and factors associated with mortality in pregnant patients who underwent ECMO. METHODS: We examined the United States National Inpatient Sample database to identify hospitalizations for pregnancy from January 1, 2010 to December 31, 2016. We identified pregnant patients who underwent ECMO using International Classification of Diseases ninth and tenth revisions codes. The primary outcome was in-hospital all-cause mortality across pregnant patients who underwent ECMO for any indication. We evaluated the indication for ECMO, incidence, prevalence of risk factors, comorbidities and conditions, and their association with in-hospital mortality. RESULTS: Fifty-nine of 5'346,517 pregnant patients underwent ECMO during our study period (incidence, 1.1; 95% confidence interval [CI], 0.84-1.4 per 100,000 hospitalizations). Indications for ECMO support included respiratory failure (79.7%), cardiogenic shock (64.4%), or circulatory arrest (25.4%). Most patients (57.6%) had more than 1 indication. The overall in-hospital mortality rate was 30.5%. Mortality was 29.8% in patients with respiratory failure, 39.5% with cardiogenic shock, 46.7% with cardiac arrest, and 42.4% in those with combined diagnoses. Cardiogenic shock was associated with a significantly higher mortality rate and adjusted odds ratio 5.0 (95% CI, 1.25-27.0). Most patients (62.7%) had one or more comorbidities. CONCLUSIONS: The frequency of ECMO use across the pregnant population was low over this time period, with a mortality rate of 1 in 3 patients. Mortality was greatest in patients with cardiogenic shock. Further work is needed to understand how best to improve ECMO outcomes in pregnant patients.

Predictors of ICU admission associated with gastrointestinal endoscopy in medical inpatients: A retrospective cohort study.

BACKGROUND AND AIM: Gastrointestinal (GI) endoscopic procedures are commonly performed in medical inpatients. Limited prior research has examined factors associated with intensive care unit (ICU) admission after GI endoscopy in medical inpatients. METHODS: This retrospective cohort study was conducted using routinely-collected clinical and administrative data from all general medicine hospitalizations at five academic hospitals in Toronto, Canada between 2010 and 2020. We describe ICU admission and death within 48 h of GI endoscopy in medical inpatients. We examined adjusted associations of patient and procedural factors with ICU admission or death using multivariable logistic regression. RESULTS: Among 18 290 medical inpatients who underwent endoscopy, 900 (4.9%) required ICU admission or died within 48 h of endoscopy. Following risk adjustment, ICU admission or death were associated with the following procedural factors: endoscopy on the day of hospital admission (aOR 3.16 [2.38-4.21]) or 1 day after admission (aOR 1.92 [1.51-2.44]) and esophagogastroduodenoscopy (EGD) procedures; and the following patient factors: Charlson comorbidity index of two (aOR 1.38 [1.05-1.81]) or three or greater (aOR 1.84 [1.47-2.29]), older age, male sex, lower hemoglobin prior to endoscopy, increased creatinine prior to endoscopy, an admitting diagnosis of liver disease and certain medications (antiplatelet agents and corticosteroids). CONCLUSIONS: ICU admission or death after endoscopy was associated with procedural factors such as EGD and timing of endoscopy, and patient factors indicative of acute illness and greater comorbidity. These findings can contribute to improved triage and monitoring for patients requiring inpatient endoscopy.

Breastfeeding Patterns in Mothers with Inflammatory Bowel Disease: A Pilot Prospective Longitudinal Study.

BACKGROUND: Breastfeeding practices in patients with inflammatory bowel disease (IBD) remain unknown. We aimed to characterize these practices and describe factors that may lead to early discontinuation. METHODS: This was a pilot, prospective, longitudinal study enrolling mothers with IBD from 2014 to 2017. Patients completed surveys on breastfeeding at time of delivery and up to 12 months postpartum. Breastfeeding discontinuation rates were reported for all patients with IBD and compared between patients with ulcerative colitis and Crohn's disease. Reproductive knowledge was defined using the Crohn's and Colitis Pregnancy Knowledge score. The Mann-Whitney U test assessed for differences between continuous variables, whereas categorical variables were compared using the chi-square test. RESULTS: A total of 74 mothers with IBD were included, 47 with ulcerative colitis and 27 with Crohn's disease. Breastfeeding rates in mothers with IBD was 94.6% at delivery, 73.9% at 3 months postpartum, 55.2% at 6 months postpartum, and 30.1% at 12 months postpartum. The most common reasons for discontinuing breastfeeding before 6 months postpartum included perceived insufficient milk production and concerns of infant medication exposure through breast milk. Compared with those who continued breastfeeding beyond 6 months postpartum, those who discontinued had lower median Crohn's and Colitis Pregnancy Knowledge scores (14.0 vs 9.0; P = .04). CONCLUSIONS: Though most mothers with IBD initiate breastfeeding at time of delivery, about half continue beyond 6 months postpartum. Common reasons for this include perceived insufficient milk production and medication concerns. Larger studies are required to validate our findings in more generalizable settings such as primary and secondary care.

A Dedicated Pregnancy Clinic Improves Reproductive Knowledge in Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Factors affecting pregnancy-related knowledge in women with inflammatory bowel disease (IBD) remain unknown. We aimed to determine these factors and to assess the impact of a dedicated pregnancy clinic on improving knowledge in women with IBD. METHODS: Adult women with IBD attending the pregnancy IBD clinic at the University of Alberta from 2014 to 2018 were enrolled. Each patient completed the Crohn's and Colitis Pregnancy Knowledge (CCPKnow) questionnaire at baseline and after individualized education delivered at each clinic visit. Knowledge levels were defined as very good if CCPKnow scores ≥ 14. Mean CCPKnow scores were reported with standard deviations (SD) and compared using the paired T test. RESULTS: The mean CCPKnow score in 117 patients at baseline was 9.65 (SD 4.18). Compared to those with disease duration < 5 years, those with disease duration > 5 years had higher rates of very good baseline knowledge (3.0% vs. 26.4%, p = 0.036). Similarly, those on preconception IBD-related therapy were more likely to have very good knowledge compared to those on no therapy (22.5% vs. 0%, p = 0.024). Fifty-one patients completed a post-clinic CCPKnow survey with a mean CCPKnow of 10.72 (SD 4.32). Participation in a pregnancy clinic improved reproductive knowledge in those with ulcerative colitis (p = 0.001), disease duration > 5 years (p = 0.017), those with at least a university education (p = 0.014) and those on IBD-related therapies (p = 0.026). CONCLUSIONS: Increased disease duration and preconception IBD-related therapy may be associated with increased pregnancy-related knowledge. A dedicated pregnancy clinic can improve reproductive knowledge in women with IBD.
