Inflammatory bowel disease-associated colorectal cancer negatively affects surgery outcomes and health care costs.

BACKGROUND: Inflammatory bowel disease may affect the pathogenesis and clinicopathologic course of colorectal cancer. We sought to characterize the impact of inflammatory bowel disease on outcomes after colectomy and/or proctectomy for a malignant indication. METHODS: Patients diagnosed with colorectal cancer as well as a pre-existing comorbid diagnosis of Crohn's disease or ulcerative colitis between 2018 and 2021 were identified from Medicare claims data. The postoperative textbook outcome was defined as the absence of complications, as well as no extended hospital stay, 90-day readmission, or mortality. Postdischarge disposition and expenditures were also examined. RESULTS: Among 191,684 patients with colorectal cancer, 4,770 (2.5%) had a pre-existing diagnosis of inflammatory bowel disease. Patients with inflammatory bowel disease-associated colorectal cancer were less likely to undergo surgical resection (no inflammatory bowel disease: 47.6% vs inflammatory bowel disease: 42.1%; P < .001). Among patients who did undergo colorectal surgery, individuals with inflammatory bowel disease were less likely to achieve a textbook outcome (odds ratio 0.64 [95% confidence interval 0.58-0.70]). In particular, patients with inflammatory bowel disease had higher odds of postoperative complications (odds ratio 1.24 [1.12-1.38]), extended hospital stay (odds ratio 1.41 [1.27-1.58]), and readmission within 90 days (odds ratio 1.56 [1.42-1.72]) (all P < .05). Patients with inflammatory bowel disease-associated colorectal cancer were less likely to be discharged to their home under independent care (odds ratio 0.77 [0.68-0.87]) and had 12.2% higher expenditures, which correlated with whether the patient had a postoperative textbook outcome. CONCLUSION: One in 40 patients with colorectal cancer had concomitant inflammatory bowel disease. Inflammatory bowel disease was associated with a lower probability of achieving ideal postoperative outcomes, higher postdischarge expenditure, as well as worse long-term survival after colorectal cancer resection.

Savings in social expenditures for work incapacity in patients with inflammatory bowel disease depend on access to innovative therapies in Poland.

OBJECTIVES: Inflammatory bowel diseases (IBD) are an increasing burden for societies. We examined Polish Social Insurance Institution (ZUS) work incapacity expenditures for people with IBD compared with the general population. METHODS: Aggregate data were obtained on ZUS expenditures between 2012 and 2021 in Polish zlotys (PLN). Annual work incapacity benefit expenditures were analyzed and IBD benefit expenditures were examined relative to innovative IBD drug utilization in individual provinces. RESULTS: Between 2012 and 2021, annual ZUS expenditures per person increased, while expenditures per IBD patient decreased. Proportionally, absenteeism was the largest ZUS expenditure in the general population, while disability pensions were the largest in the IBD population. ZUS expenditures due to absenteeism in the general population increased by PLN 282 per person; those due to disability pensions decreased by PLN 85. Disability pension spending due to Crohn's disease (CD) and ulcerative colitis (UC) decreased by PLN 371 and PLN 284, respectively, while absenteeism spending per person with CD and UC decreased (PLN 58 and PLN 35, respectively). Nationwide in 2021, 8.5% of people with CD and 1.9% of those with UC received innovative drugs. The percentage of people receiving innovative drugs and ZUS expenditure per person were inversely related in 9/16 provinces for CD and 5/16 for UC. CONCLUSION: Polish state spending on work incapacity benefits increased in the general population but decreased in people with IBD between 2012 and 2021. Use of innovative drugs was associated with reduced spending per person with IBD in some provinces.

Substantial cost savings of ultrasound-based management over magnetic resonance imaging-based management in an inflammatory bowel disease service.

BACKGROUND: Imaging is used to monitor disease activity in small bowel Crohn's disease (CD). Magnetic Resonance Enterography is often employed as a first modality in the United Kingdom for assessment and monitoring; however, waiting times, cost, patient burden and limited access are significant. It is as yet uncertain if small bowel intestinal ultrasound (IUS) may be a quicker, more acceptable, and cheaper alternative for monitoring patients with CD. METHODS: A clinical service evaluation of imaging pathways was undertaken at a single NHS site in England, United Kingdom. Data were collected about patients who were referred and underwent an imaging analysis for their IBD. Only patients who underwent a therapy change were included in the analysis. Data were collected from care episodes between 01 January 2021-30 March 2022. RESULTS: A combined total of 193 patient care episodes were reviewed, 107 from the IUS pathway and 86 from the MRE pathway. Estimated costs per patient in the IUS pathway was £78.86, and £375.35 per patient in the MRE pathway. The MRE pathway had an average time from referral to treatment initiation of 91 days (SD= ±61) with patients in the IUS pathway waiting an average of 46 days (SD= ±17). CONCLUSIONS: Findings from this work indicate that IUS is a potential cost-saving option when compared to MRE when used in the management of CD. This is in addition to the cost difference of the radiological modalities. A large, multicentre, prospective study is needed to validate these initial findings.

What is already known on this topic ­ Ultrasound is a quick and accurate imaging investigation for patients living with Crohn's disease. Its effect on the cost utility of an Inflammatory Bowel Disease service is unknown.What this study adds ­ This work provides initial data suggesting that an ultrasound-based service may provide significant cost savings when compared to a magnetic resonance imaging-based service.How this study might affect research, practice, or policy ­ This work is part of a larger programme of work to investigate the barriers to wider ultrasound implementation in UK IBD services. This work will contribute to the design of an implementation and training package for intestinal ultrasound in the UK.

Financial toxicity among patients undergoing resectional surgery for inflammatory bowel disease in the United States.

AIM: Financial toxicity describes the financial burden and distress that patients experience due to medical treatment. Financial toxicity has yet to be characterized among patients with inflammatory bowel disease (IBD) undergoing surgical management of their disease. This study investigated the risk of financial toxicity associated with undergoing surgery for IBD. METHODS: This study used a retrospective analysis using the National Inpatient Sample from 2015 to 2019. Adult patients who underwent IBD-related surgery were identified using the International Classification of Diseases (10th Revision) diagnostic and procedure codes and stratified into privately insured and uninsured groups. The primary outcome was risk of financial toxicity, defined as hospital admission charges that constituted 40% or more of patient's post-subsistence income. Secondary outcomes included total hospital admission cost and predictors of financial toxicity. RESULTS: The analytical cohort consisted of 6412 privately insured and 3694 uninsured patients. Overall median hospital charges were $21 628 (interquartile range $14 758-$35 386). Risk of financial toxicity was 86.5% among uninsured patients and 0% among insured patients. Predictors of financial toxicity included emergency admission, being in the lowest residential income quartile and having ulcerative colitis (compared to Crohn's disease). Additional predictors were being of Black race or male sex. CONCLUSION: Financial toxicity is a serious consequence of IBD-related surgery among uninsured patients. Given the pervasive nature of this consequence, future steps to support uninsured patients receiving surgery, in particular emergency surgery, related to their IBD are needed to protect this group from financial risk.

Effect of Medicaid expansion on inflammatory bowel disease and healthcare utilization.

BACKGROUND: Kentucky was among the first to adopt Medicaid expansion, resulting in reducing uninsured rates from 14.3% to 6.4%. We hypothesize that Medicaid expansion resulted in increased elective healthcare utilization and reductions in emergency treatments by patients suffering Inflammatory Bowel Disease (IBD). METHODS: The Hospital Inpatient Discharge and Outpatient Services Database (HIDOSD) identified all encounters related to IBD from 2009 to 2020 in Kentucky. Several demographic variables were compared in pre- and post-Medicaid expansion adoption. RESULTS: Our study analyzed 3386 pre-expansion and 24,255 post-expansion encounters for IBD patients. Results showed that hospitalization rates dropped (47.7%-8.4%), outpatient visits increased (52.3%-91.6%) and Emergency visits decreased (36.7%-11.4%). Admission following a clinical referral similarly increased with a corresponding drop in emergency room admissions. Hospital costs and lengths of stay also dropped following Medicaid expansion. CONCLUSION: In the IBD population, Medicaid expansion improved access to preventative care, reduced hospital costs by decreasing emergency care, and increased elective care pathways.

Major ambulatory surgery among US adults with inflammatory bowel disease, 2017.

BACKGROUND: Patients with inflammatory bowel disease (IBD) have higher health services use than those without IBD. We investigated patient and hospital characteristics of major ambulatory surgery encounters for Crohn's disease (CD) or ulcerative colitis (UC) vs non-IBD patients. METHODS: We conducted a cross-sectional study using 2017 Nationwide Ambulatory Surgery Sample. Major ambulatory surgery encounters among patients aged ≥18 years with CD (n = 20,635) or UC (n = 9,894) were compared to 9.4 million encounters among non-IBD patients. Weighted percentages of patient characteristics (age, sex, median household income, primary payers, patient location, selected comorbidities, discharge destination, type of surgeries) and hospital-related characteristics (hospital size, ownership, location and teaching status, region) were compared by IBD status (CD, UC, and no IBD). Linear regression was used to estimate mean total charges, controlling for these characteristics. RESULTS: Compared with non-IBD patients, IBD patients were more likely to have private insurance, reside in urban areas and higher income zip codes, and undergo surgeries in hospitals that were private not-for-profit, urban teaching, and in the Northeast. Gastrointestinal surgeries were more common among IBD patients. Some comorbidities associated with increased risk of surgical complications were more prevalent among IBD patients. Total charges were 9% lower for CD patients aged <65 years (Median: $16,462 vs $18,106) and 6% higher for UC patients aged ≥65 years (Median: $16,909 vs $15,218) compared to their non-IBD patient counterparts. CONCLUSIONS: Differences in characteristics of major ambulatory surgery encounters by IBD status may identify opportunities for efficient resource allocation and positive surgical outcomes among IBD patients.

Economic Burden and Health Care Access for Patients With Inflammatory Bowel Diseases in China: Web-Based Survey Study.

BACKGROUND: The increasing incidence of inflammatory bowel disease (IBD) has imposed heavy financial burdens for Chinese patients; however, data about their financial status and access to health care are still lacking. This information is important for informing patients with IBD about disease treatment budgets and health care strategies. OBJECTIVE: The aim of this study was to evaluate the economic status and medical care access of patients with IBD through the China Crohn's & Colitis Foundation web-based platform in China. METHODS: Our study was performed in 14 IBD centers in mainland China between 2018 and 2019 through WeChat. Participants were asked to complete a 64-item web-based questionnaire. Data were collected by the Wenjuanxing survey program. We mainly focused on income and insurance status, medical costs, and access to health care providers. Respondents were stratified by income and the associations of income with medical costs and emergency visit times were analyzed. RESULTS: In this study, 3000 patients with IBD, that is, 1922 patients with Crohn disease, 973 patients with ulcerative colitis, and 105 patients with undetermined colitis were included. During the last 12 months, the mean (SD) direct and indirect costs for per patient with IBD were approximately US $11,668.68 ($7944.44) and US $74.90 ($253.60) in China. The average reimbursement ratios for most outpatient and inpatient costs were less than 50%. However, the income of 85.5% (2565/3000) of the patients was less than ¥10,000 (US $1445) per month. Approximately 96.5% (2894/3000) of the patients were covered by health insurance, but only 24.7% (741/3000) of the patients had private commercial insurance, which has higher imbursement ratios. Nearly 98.0% (2954/3000) of the patients worried about their financial situation. Thus, 79.7% (2392/3000) of the patients with IBD tried to save money for health care and even delayed their medical treatments. About half of the respondents (1282/3000, 42.7%) had no primary care provider, and 52.2% (1567/3000) of the patients had to visit the emergency room 1-4 times per year for the treatment of their IBD. Multivariate analysis revealed that lower income (P=.001) and higher transportation (P=.004) and accommodation costs (P=.001) were significantly associated with the increased number of emergency visits of the patients. CONCLUSIONS: Chinese patients with IBD have enormous financial burdens and difficulties in accessing health care, which have increased their financial anxiety and inevitably influenced their disease outcomes. Early purchase of private insurance, thereby increasing the reimbursement ratio for medical expenses, and developing the use of telemedicine would be effective strategies for saving on health care costs.

A Phenome-Wide Analysis of Healthcare Costs Associated with Inflammatory Bowel Diseases.

INTRODUCTION: Crohn's disease (CD) and ulcerative colitis (UC) are associated with considerable direct healthcare costs. There have been few comprehensive analyses of all IBD- and non-IBD comorbidities that determine direct costs in this population. METHODS: We used data from a validated cohort of patients with inflammatory bowel disease (IBD). Total healthcare costs were estimated as a sum of costs associated with IBD-related hospitalizations and surgery, imaging (CT or MR scans), outpatient visits, endoscopic evaluation, and emergency room (ER) care. All ICD-9 codes were extracted for each patient and clustered into 1804 distinct phecode clusters representing individual phenotypes. A phenome-wide association analysis (PheWAS) was performed using logistic regression to identify predictors of being in the top decile of costs. RESULTS: Our cohort is comprised of 10,721 patients with IBD among whom 50% had CD. The median age was 46 years. The median total cost per patient is $11,203 (IQR $2396-30,563). The strongest association with total healthcare costs was intestinal obstruction without mention of hernia (p = 5.93 × 10-156) and other intestinal obstruction (p = 9.24 × 10-131). In addition, strong associations were observed for symptoms consistent with severity of IBD including the presence of fluid-electrolyte imbalance (p = 1.90 × 10-130), hypovolemia (p = 1.65 × 10-114), abdominal pain (p = 7.29 × 10-60), and anemia (p = 1.90-10-83). Cardiopulmonary diseases and psychological comorbidity also demonstrated significant associations with total costs with the latter being more strongly associated with ER visit-related costs. CONCLUSIONS: Surrogate markers suggesting possible irreversible bowel damage and active disease demonstrate the greatest influence on IBD-related healthcare costs.

Women's Earnings are more Affected by Inflammatory Bowel Disease than Men's: A Register-Based Swedish Cohort Study.

BACKGROUND AND AIMS: Patients with inflammatory bowel disease [IBD] are subject to more work disability than the general population. We aimed to estimate the monetary cost of IBD for the individual through assessment of earnings in relation to diagnosis. METHODS: Through linkage of national registers, we identified patients aged 30-55 years at first IBD diagnosis in Sweden in 2002-2011, and same-sex IBD-free siblings. We estimated taxable earnings and disposable income from 5 years before to 5 years after diagnosis. RESULTS: The 5961 patients [27% Crohn's disease, 68% ulcerative colitis, 4.3% IBD unclassified] had similar taxable earnings to their 7810 siblings until the year of diagnosis, when earnings decreased and remained lower than for siblings during follow-up. The adjusted difference in earnings over the entire 5-year period after diagnosis was -5% [-8212€; 95% confidence interval: -11 458 to -4967€]. The difference was greater in women than in men, and greater in Crohn's disease than in ulcerative colitis. When stratifying for sex and IBD subtype and comparing earnings during each year of follow-up, median annual earnings were lower in women with Crohn's disease and ulcerative colitis than in their sisters during all years of follow-up, whereas the men had similar annual taxable earnings to their brothers. Disposable income was similar between patients and siblings during the investigated time period. CONCLUSION: From the year of diagnosis and at least 5 years onwards, patients with IBD had 5% lower earnings than siblings, mainly explained by differences between women with IBD and their sisters. However, there were no differences in disposable income.

Potential Cost Implications of Mandatory Non-Medical Switching Policies for Biologics for Rheumatic Conditions and Inflammatory Bowel Disease in Canada.

In 2018, TNFα inhibitors were the highest cost drug class for Canadian public drug programs. In 2019, two Canadian provinces announced mandatory nonmedical switching policies in an attempt to reduce their costs by increasing biosimilar uptake. The national impact of similar policies across Canada is unknown. We conducted a cross-sectional analysis of monthly publicly funded prescription claims for infliximab, etanercept, and adalimumab between June 2015 and December 2019. We reported the market share of biosimilars for infliximab and etanercept in 2019 for each province and estimated the cost savings that public payers could have realized in 2019 if mandatory switching policies had been implemented across Canada, including a sensitivity analysis, which assumed that governments receive a 25% rebate on all biologics. Provincial drug programs spent CAD $991.84 million on infliximab, etanercept, and adalimumab in 2019, and, when biosimilars were available, they constituted only 15.5% of national utilization of these drugs. In British Columbia, the implementation of a mandatory switching policy for patients with rheumatic conditions increased the biosimilar market share of infliximab and etanercept by 299% (from 19.7% to 78.5%). If applied nationwide to all three biologics for all indications, we estimate such policies could lead to annual savings of between CAD $179.71 million and CAD $425.64 million nationally. The overall market share of biosimilars remains low in all provinces where mandatory switching policies have not been introduced. The cost implications of successfully increasing biosimilar uptake would be substantial, particularly as more biosimilars reach the Canadian market.

Mental Health Costs of Inflammatory Bowel Diseases.

BACKGROUND: Mental health diagnoses (MHDs) were identified as significant drivers of inflammatory bowel disease (IBD)-related costs in an analysis titled "Cost of Care Initiative" supported by the Crohn's & Colitis Foundation. In this subanalysis, we sought to characterize and compare IBD patients with and without MHDs based on insurance claims data in terms of demographic traits, medical utilization, and annualized costs of care. METHODS: We analyzed the Optum Research Database of administrative claims from years 2007 to 2016 representing commercially insured and Medicare Advantage insured IBD patients in the United States. Inflammatory bowel disease patients with and without an MHD were compared in terms of demographics (age, gender, race), insurance type, IBD-related medical utilization (ambulatory visits, emergency department [ED] visits, and inpatient hospitalizations), and total IBD-related costs. Only patients with costs >$0 in each of the utilization categories were included in the cost estimates. RESULTS: Of the total IBD study cohort of 52,782 patients representing 179,314 person-years of data, 22,483 (42.6%) patients had at least 1 MHD coded in their claims data with a total of 46,510 person-years in which a patient had a coded MHD. The most commonly coded diagnostic categories were depressive disorders, anxiety disorders, adjustment disorders, substance use disorders, and bipolar and related disorders. Compared with patients without an MHD, a significantly greater percentage of IBD patients with MHDs were female (61.59% vs 48.63%), older than 75 years of age (9.59% vs 6.32%), white (73.80% vs 70.17%), and significantly less likely to be younger than 25 years of age (9.18% vs 11.39%) compared with those without mental illness (P < 0.001). Patients with MHDs had significantly more ED visits (14.34% vs 7.62%, P < 0.001) and inpatient stays (19.65% vs 8.63%, P < 0.001) compared with those without an MHD. Concomitantly, patients with MHDs had significantly higher ED costs ($970 vs $754, P < 0.001) and inpatient costs ($39,205 vs $29,550, P < 0.001) compared with IBD patients without MHDs. Patients with MHDs also had significantly higher total annual IBD-related surgical costs ($55,693 vs $40,486, P < 0.001) and nonsurgical costs (medical and pharmacy) ($17,220 vs $11,073, P < 0.001), and paid a larger portion of the total out-of-pocket cost for IBD services ($1017 vs $905, P < 0.001). CONCLUSION: Patients whose claims data contained both IBD-related and MHD-related diagnoses generated significantly higher costs compared with IBD patients without an MHD diagnosis. Based on these data, we speculate that health care costs might be reduced and the course of patients IBD might be improved if the IBD-treating provider recognized this link and implemented effective behavioral health screening and intervention as soon as an MHD was suspected during management of IBD patients. Studies investigating best screening and intervention strategies for MHDs are needed.

Relapse rate following withdrawal of anti-TNF therapy in patients with inflammatory bowel disease: A real-life cohort from northern India.

BACKGROUND: The decision to withdraw anti-tumor necrosis factor (anti-TNF) therapy in patients with inflammatory bowel disease (IBD) remains controversial, especially in the developing world, where its long-term use is restrained by side effects and prohibitive cost. Present study evaluated the relapse rate and its predictors following anti-TNF withdrawal in a cohort of IBD patients from northern India. METHODS: Patients with IBD who received anti-TNF therapy (induction and beyond), and were under follow-up at All India Institute of Medical Sciences, New Delhi, from January 2005 to July 2018 were included. Demographic features, disease characteristics, duration, response to anti-TNF therapy, and relapse rate after its withdrawal were analyzed. RESULTS: Among 4600 patients with IBD under follow-up, 90 (1.9%) received anti-TNF therapy, of whom 11 were excluded (8-complete records unavailable; 3-received only single dose). Of 79 patients (mean age-40.1 ± 14.2 years; 53.2% males; 31 [39.2%] ulcerative colitis, 47 [59.5%] Crohn's disease; median follow-up-24 [12-39] months), 9 (11.4%) were primary non-responders, 19 (24.1%) had secondary loss of response, and 51 (64.5%) maintained clinical response on anti-TNF. Anti-TNF was withdrawn in 45 (57%) patients (major causes: financial burden-16.5%; tubercular reactivation-12.7%), of whom 33 were in clinical remission. Over a median follow-up of 26 (7.5-45) months, 15 patients (45.5%) relapsed. Most of them responded to antibiotics, steroids, or anti-TNF agents; only 3 required surgery. On Kaplan-Meier analysis, long disease duration prior to therapy was a significant predictor of relapse (hazard ratio [HR] = 1.33, p = 0.034). CONCLUSION: Almost 50% patients with IBD in clinical remission relapse within a year of anti-TNF withdrawal. However, most of these patients have a favorable disease course and respond to medical therapy.

An Indian national survey of therapeutic drug monitoring with anti-tumor necrosis (TNF) medications in inflammatory bowel disease.

BACKGROUND: Evidence supports therapeutic drug monitoring (TDM) in improving efficacy and cost-effectiveness of anti-TNF therapy in inflammatory bowel disease (IBD). Data on perceptions and barriers to TDM use are limited and no data are available from India. Our objective was to assess clinicians' attitudes and barriers to TDM use in IBD. METHODS: A 16-question survey was distributed to members of the Indian Society of Gastroenterology. Information on clinician characteristics, demographics, use and barriers towards TDM with anti-TNFs was collected. Logistic regression was used to predict factors influencing TDM use. RESULTS: Two hundred and forty-two respondents participated (92.5% male); 83% were consultant gastroenterologists. Of 104 respondents meeting inclusion criteria (treating > 5 IBD patients and at least 1 with an anti-TNF per month), complete responses were available for 101 participants. TDM was utilized by 20% (n = 20) of respondents. Of them, 89.5% (n = 17) used TDM for secondary loss of response; 73.7% (n = 14) for primary non-response and 5.3% (n = 1) proactively. Barriers to TDM use were cost (71.2%), availability (67.8%), time lag in results (58.7%) and the perception that TDM is time-consuming (45.7%). Clinicians treating > 30 IBD patients were more likely to check TDM (OR = 4.9, p = 0.02). Of 81 respondents not using TDM, 97.5% (n = 79) would do so if all the barriers were removed. CONCLUSION: Significant barriers to TDM use were availability, cost and time lag for results. If these barriers were removed, almost all the clinicians would use TDM at least reactively and 25% would use proactively. There is an urgent need to address these barriers and optimize anti-TNF therapy for optimal outcomes.

Complications of enterostomy and related risk factor analysis of very early onset inflammatory bowel disease with interleukin-10 signalling deficiency: a single-centre retrospective analysis.

BACKGROUND: Interleukin-10 (IL10) signalling pathway deficiency results in severe very early onset inflammatory bowel disease (VEOIBD), and enterostomy is often inevitable. However, studies in these surgical populations are lacking. This study aims to determine the enterostomy characteristics, postoperative complications and related risk factors in enterostomy patients. METHODS: From March 1, 2015, to December 31, 2018, patients with IL10R-mutation who underwent enterostomy were recruited for analysis. We collected data on the patients' clinical characteristics, enterostomy characteristics, postoperative complications and related risk factors. RESULTS: Twelve patients required emergency enterostomy, and 10 patients underwent elective enterostomy. Twelve patients experienced postoperative complications, including wound infection (27.3%), wound dehiscence (18.2%), reoperation (18.2%), etc. Compared with the pre-enterostomy values, there was a decrease in C-reactive protein (CRP) (P = 0.001), an increase in albumin (P = 0.001) and an improvement in the weight-for-age (P = 0.029) and body mass index (BMI) Z-scores (P = 0.004) after enterostomy. There was a significant difference between the pre-operation and postoperation medicine expenses (P = 0.002). Univariate binary logistic regression analysis revealed a statistically significant influence of CRP (OR: 1.43, 95% CI: 1.07-1.91, P = 0.016) and a tendency towards a significant influence of intestinal perforation, albumin level, BMI Z-score and weighted paediatric Crohn's disease activity index (wPCDAI). Multivariate logistic regression analysis showed that CRP (OR: 1.40), wPCDAI (OR: 2.88) and perforation (OR: 1.72) showed a tendency to behave as independent risk factors for postoperative complications, but the results were not significant (all P > 0.05). CONCLUSIONS: Surgery and enterostomy showed benefits for VEOIBD with IL-10 signalling deficiency. The timing of intervention, potential postoperative complications, economic burden and other related problems should be considered.

Viewpoint: Inflammatory Bowel Diseases Among Immigrants From Low- to High-Incidence Countries: Opportunities and Considerations.

The inflammatory bowel diseases [IBDs], inclusive of Crohn's disease [CD] and ulcerative colitis [UC], are chronic, progressive immune-mediated diseases associated with high morbidity and substantial economic impact. The pathogenesis implicates a complex interaction between environmental determinants and genetic susceptibility. Of concern, the incidence and prevalence of IBD are increasing globally, with the highest relative increase observed in developing and recently developed countries. One high-risk yet underappreciated population is immigrants from countries of low to high IBD incidence, as evidenced by epidemiologic studies demonstrating higher risk of IBD among second- versus first-generation and younger versus older immigrants from low- to high-incidence countries [LTHICs]. The reasons underlying these emerging patterns among immigrants are incompletely understood and provide enormous opportunities to better define the pathophysiology of IBD and move toward disease prevention or at least earlier diagnosis. The rapidity of this epidemiologic shift in the demographic profile of IBD, which was traditionally a disease of Caucasians in industrialized countries, strongly implicates non-genetic factors and gene-environment interactions in the pathophysiology of IBD among immigrants from LTHICs. The primary objectives of this Viewpoint are to [1] provide a focused overview of IBD epidemiology among immigrants from countries at differential IBD risk; [2] emphasize the potential to advance our understanding of IBD pathogenesis via targeted research efforts to delineate risk and protective determinants in this cohort; and [3] highlight disparities and barriers in IBD care, as well as the economic implications of the rising, yet underappreciated, disease burden among immigrants from LTHICs.

Changes in Direct Healthcare Costs before and after the Diagnosis of Inflammatory Bowel Disease: A Nationwide Population-Based Study.

Background/Aims: We aimed to investigate the differences in direct healthcare costs between patients with and without inflammatory bowel disease (IBD) and changes in direct healthcare costs before and after IBD diagnosis. Methods: This population-based study identified 34,167 patients with IBD (11,014 patients with Crohn's disease and 23,153 patients with ulcerative colitis) and 102,501 age-and sex-matched subjects without IBD (the control group) from the National Health Insurance database using the International Classification of Disease, 10th revision codes and the rare intractable disease registration program codes. The mean healthcare costs per patient were analyzed for 3 years before and after IBD diagnosis, with follow-up data available until 2015. Results: Total direct healthcare costs increased and peaked at $2,396 during the first year after IBD diagnosis, but subsequently dropped sharply to $1,478 during the second year after diagnosis. Total healthcare costs were higher for the IBD patients than for the control group, even in the third year before the diagnosis ($497 vs $402, p<0.001). The costs for biologics for the treatment of IBD increased steeply over time, rising from $720.8 in the first year after diagnosis to $1,249.6 in the third year after diagnosis (p<0.001). Conclusions: IBD patients incurred the highest direct healthcare costs during the first year after diagnosis. IBD patients had higher costs than the control group even before diagnosis. The cost of biologics increased steeply over time, and it can be assumed that biologics could be the main driver of costs during the early period after IBD diagnosis.

Disease-Associated Costs in Children With Inflammatory Bowel Disease: A Systematic Review.

BACKGROUND: As a chronic noncurable disorder often diagnosed in childhood or adolescence, inflammatory bowel disease (IBD) confers a significant financial lifetime burden. The objective of this systematic review was to determine the disease-associated costs (both direct and indirect) associated with IBD in children and young adults. METHODS: We conducted a systematic review of the literature and included any study reporting direct health services-related costs or the indirect economic burden of IBD in persons aged ≤19 years (PROSPERO protocol number CRD2016036128). A technical panel of experts in pediatric gastroenterology and research methodology formulated the review questions, reviewed the search strategies and review methods, and provided input throughout the review process. RESULTS: Nine studies met criteria for inclusion, 6 of which examined direct costs, 1 of which examined both direct and indirect costs, 1 of which assessed indirect costs, and 1 of which assessed out-of-pocket (OOP) costs. Inflammatory bowel disease-associated costs were significantly higher compared with costs in non-IBD populations, with wide variations in cost estimates, which prevented us from conducting a meta-analysis. Costs in Crohn's disease were higher than in ulcerative colitis. Overall, direct costs shifted from inpatient hospitalization as a major source of direct costs to medications, mainly driven by anti-tumor necrosis factor agents, as the leading cause of direct costs. Predictors of high costs included uncontrolled disease, corticosteroid treatment in the previous year, and comorbidity burden. CONCLUSIONS: The pediatric literature examining IBD-attributable costs is limited, with widely variable cost estimates. There is a significant knowledge gap in the research surrounding indirect costs and OOP expenses.
