A Nationwide Survey on Patient Empowerment in Pediatric Inflammatory Bowel Disease in Germany.

The incidence/prevalence of pediatric inflammatory bowel disease (IBD) is increasing. IBD places a significant burden on young patients during important developmental stages and affects their families. Children and adolescents with IBD require increased support from health care services. However, little is known about the additional support needed and how to provide it. Therefore, a large survey was conducted with a focus on patient empowerment. For the anonymous survey, called CEDNA, a patient questionnaire for adolescents with IBD and a questionnaire for parents of children and adolescents with IBD were made available throughout Germany (distributed n = 2810). Questions covered various aspects of coping with the disease, utilization of care, use and need of information and communication services, and how information should be provided. From October 2021 to April 2022, 1158 (n = 708 parents (61.1%), n = 450 patients (38.9%)) questionnaires were completed. The results show a deficit in pediatric IBD care and revealed a large gap in knowledge about core IBD topics (e.g., 74.8% of patients feel poorly informed about transition, 62.4% know little about patient organizations and self-help groups, and 54.7% have little information about preventive health measures), indicating a low level of health literacy among affected children and adolescents. Pediatric IBD poses significant challenges for patients, their families, and healthcare teams. By empowering patients and families, and providing targeted information and communication tailored to the age of the child or adolescent and the needs of the parents, care can be improved and better adapted to the needs of patients. Actions would include providing quality information online through scientific societies and patient organizations and facilitating self-management in adolescents.

Application of the capture–recapture method to ascertain the completeness of the Saxon pediatric IBD registry in Germany

AimThe incidence of inflammatory bowel disease (IBD) is increasing worldwide. The Saxon Pediatric IBD Registry was founded in 2000 to describe the epidemiology of pediatric IBD in Germany. The aim of this study was to determinate the completeness of this registry for children and adolescents younger than 15 years and to make this approach transparent. Results of this completeness update have broad implications for further scientific publications from the registry dataset.MethodThe capture–recapture method with two data sources was used to ascertain completeness. A second data source was collected in 2019 for the observation period 2008–2014 from all pediatricians, gastroenterologists, and internists working in practices in a predefined region in Saxony, Germany.ResultsA total of 23 patients with IBD were reported who fulfilled the inclusion criteria. One of them was not recorded in the registry. Therefore, the completeness of the registry was estimated at 95.7% (95% CI 90.2–100). Initial analysis of the Saxon Pediatric IBD Registry over the 15-year period 2000–2014 includes 532 patients, 312 (58.6%) male and 220 (41.4%) female. The distribution of single IBD diseases in the registry was as follows: Crohn’s disease 338 patients (63.5%), ulcerative colitis 176 patients (33.1%), and unclassified IBD 18 patients (3.4%). Evaluations by sex and by disease in age groups and by age at onset were tabulated.ConclusionThis study demonstrates that the completeness level of the Saxon Pediatric IBD Registry is high (95.7%), and thus the epidemiological data of the registry are reliable.

Current and projected incidence trends of pediatric-onset inflammatory bowel disease in Germany based on the Saxon Pediatric IBD Registry 2000-2014 -a 15-year evaluation of trends.

AimsAn increasing number of children and adolescents worldwide suffer from inflammatory bowel disease (IBD) such as Crohn’s disease (CD) and ulcerative colitis (UC). The present work aims to investigate the incidence, prevalence and future trends of IBD in children and adolescents in Saxony, Germany.MethodsThe Saxon Pediatric IBD Registry collected data on patients up to 15 years of age from all 31 pediatric hospitals and pediatric gastroenterologists in Saxony over a 15-year period (2000–2014). In 2019, an independent survey estimated a registry completeness of 95.7%. Age-standardized incidence rates (ASR) per 100,000 person-years (PY) and prevalence per 100,000 children and adolescents were calculated. Evaluation was also been performed in sex and age subgroups. Joinpoint and Poisson regression were used for trend analyses and projections.Results532 patients with confirmed IBD during 2000–2014 were included in the epidemiological evaluation. 63.5% (n = 338) patients had CD, 33.1% (n = 176) had UC and 3.4% (n = 18) had unclassified IBD (IBD-U). The 15-year IBD prevalence was 111.8 [95%-CI: 102.3–121.3] per 100,000. The incidence ASR of IBD per 100,000 PY over the whole observation period was 7.5 [6.9–8.1]. ASR for the subtypes were 4.8 [4.3–5.3] for CD, 2.5 [2.1–2.9] for UC and 0.3 [0.1–0.4] for IBD-U. The trend analysis of ASR using the joinpoint regression confirmed a significant increase for incidence of IBD as well as CD. For IBD, the ASR per 100,000 PY increased from 4.6 [2.8–6.3] in 2000 to 8.2 [7.5–13.6] in 2014; projected incidence rates for IBD in Germany are 12.9 [6.5–25.5] in the year 2025 and 14.9 [6.7–32.8] in 2030, respectively. Thus, the number of new IBD diagnoses in Germany would more than triple (325%) in 2030 compared to 2000. The increase is expected to be faster in CD than UC, and be more in males than in females. The expected number of newly diagnosed children with IBD in Germany is projected to rise to about 1,584 [1,512–1,655] in 2025, and to about 1,918 [1,807–2,29] in 2030.ConclusionThe incidence of IBD in children and adolescents in Saxony increased at a similar rate as in other developed countries during the observation period. Given this trend, the health care system must provide adequate resources for the care of these young patients in the future.

Cannabis use of patients with inflammatory bowel disease in Germany: a cross-sectional survey.

Progressive legalization and increasing utilization of medical cannabis open up potential new applications, including for inflammatory bowel disease (IBD). This study aimed to collect current figures on the use of and experience with cannabis among IBD patients in Germany. A 71-item questionnaire was mailed to a randomly selected representative sample of 1000 IBD patients. Questionnaires were returned by 417 patients (mean age 49.1 ± 17.0 years; 55.8 % women; 43.4 % ulcerative colitis and 54.7 % Crohn's disease). Seventy-three respondents (17.5 %) stated past cannabis use for recreational purposes, while 12 users mentioned usage at the time the questionnaire was completed (2.9 %). Seventeen patients (4.1 %) indicated past use of cannabis, and 18 participants (4.3 %) reported current use of cannabis to treat IBD. Perceived benefits of cannabis use by its users included reduced abdominal pain, improved sleep quality, and relief of unease and worry. They reported lower quality of life and higher levels of anxiety or depression than non-users. Of notice, 52.9 % of cannabis users obtained their cannabis from the black market. A total of 76.5 % of former and 50 % of current users did not report their cannabis use to the physician. This survey reveals the largest data set on cannabis use among IBD patients in Germany, with the potential for further research. Cannabis is mainly procured from the black market, with unknown quality.

Cost of illness of inflammatory bowel disease in Germany

The prevalence of inflammatory bowel disease (IBD) in Germany is rising. Due to a disease onset at a young age, direct and indirect costs are important. The aim of the present study is to provide a comprehensive presentation of existing healthcare costs for these diseases in Germany and to compare them by inflation adjustments for 2018. Performing a systematic literature search, monetary costs were extracted from German and English literature. Quality and relevance of the studies were assessed with a checklist. The average outpatient cost for inflammatory bowel disease amounts between 18 and 87 Euro/pat/30 days, the average inpatient cost was between 1026 and 9083 Euro/case. Depending on the type of calculation, biologicals cause different amounts of cost. Few data are available for direct medical 82 and 618 Euro/pat/30 days, direct non-medical 63and 84 Euro/pat/30 days and indirect costs 463 and 3493Euro/pat/30 days. The total costs are about 533 Euro/pat/30 days, related to one year 6485 Euro/pat. For the first time, it is possible to compare existing medical costs for IBD in Germany. Current studies feature very heterogeneous methods and study populations of IBD.Depending on the collective, the total costs are up to 6485Euro/patient/year.

Comparative Analysis of 3-Year Persistence With Vedolizumab Compared With Antibodies Against Tumor Necrosis Factor-Alpha in Patients With Inflammatory Bowel Disease in Germany: Retrospective Analysis of a Large Prescription Database.

The goal of the study was to compare persistence with vedolizumab versus adalimumab, golimumab, and infliximab in biologics-naïve patients with inflammatory bowel disease treated in gastroenterological practices and outpatient clinics in Germany. Patients aged 18 or older who had initiated a biological therapy (vedolizumab, infliximab, adalimumab, or golimumab) were included in the present study. Prescriptions between July 2014 and March 2017 of the respective biological drug emerging from gastroenterological practices or outpatient clinics in Germany were retrieved from the longitudinal prescription (LRx) database. Patients treated with vedolizumab were matched with patients treated with infliximab, adalimumab, or golimumab on the basis of age, gender, medication before biologic therapy, and index year. The primary outcome variable of the study was the rate of persistence with vedolizumab compared with antitumor necrosis factor biologics (infliximab, adalimumab, and golimumab) within 3 years of the first prescription in outpatient settings. Kaplan-Meier analysis was performed in 15,984 patients naïve to biologics revealing the statistically lower risk of discontinuation for vedolizumab compared with adalimumab, golimumab, or infliximab. In matched-pairs analyses, within 3 years after the first prescription, 39.5% of 2076 patients were persistent to vedolizumab compared with 33.5% of matched patients persistent to adalimumab (P<0.001). 37.6% of 716 patients were persistent to vedolizumab compared with 24.7% of matched patients persistent to golimumab (P<0.001). 35.7% of 2055 patients were persistent to vedolizumab compared with 30.2% of matched patients persistent to infliximab (P=0.119). Vedolizumab was associated with a significantly lower risk of therapy discontinuation compared with adalimumab [hazard ratio (HR)=0.86; 95% confidence interval (CI), 0.81-0.93] and golimumab (HR=0.60; 95% CI, 0.54-0.67), respectively; the vedolizumab risk of therapy discontinuation was numerically lower than infliximab but statistical significance was not achieved (HR=0.93; 95% CI, 0.85-1.02). In biologics-naïve IBD patients treated in outpatient settings in Germany, matched-pair analyses showed that vedolizumab was associated with significantly improved drug persistence compared with adalimumab or golimumab, whereas numerical improvement was shown in comparison with infliximab.

Rate of Adverse Events and Associated Health Care Costs for the Management of Inflammatory Bowel Disease in Germany

Therapeutic management of inflammatory bowel disease (IBD) is challenging, and available therapies are associated with adverse events (AEs) that may lead to treatment discontinuation. This study evaluated the rate of drug-related AEs of special interest (AESIs) associated with IBD therapies and compare health care costs among patients with IBD who did and did not experience AESIs. A retrospective cohort analysis was conducted using claims data from a German Sickness Fund (Allgemeine Ortskrankenkasse PLUS). Patients were diagnosed with ulcerative colitis (UC) or Crohn's disease (CD) and newly initiating treatment with immunosuppressant, anti-tumor necrosis factor α, or anti-integrin therapies from January 1, 2011, to December 31, 2015. Patients were required to have continuous insurance coverage and no evidence of use of these IBD therapies for 12 months before the date of newly initiating therapy (index date). Rates of AESIs were based on 28 different events or chronic conditions associated with IBD treatment. Direct health care costs were reported separately for patients who did or did not experience AESIs. Only treatment periods lasting ≥60 days were considered. AESI rates related to all possible treatment patterns were calculated and reported as the number of events per 10,000 patient-years. Health care costs were calculated based on IBD-related health care resource use. A total of 1126 (CD, n=676; UC, n=450) patients met the inclusion criteria. Mean age was 36.5 years for patients with CD and 42.5 years for patients with UC; 60.5% and 47.6% were female, respectively. Median observed time since the index date was 1460 and 1552 days, for patients with CD and UC. The overall rate for any AESI was 1392.4 and 1917.9 events per 10,000 patient-years in patients with CD and those with UC. Severe infections and diabetes mellitus were the most common AESIs. Significant differences in mean total direct health care costs were found for CD patients with AESIs versus those without (€8920.08 and €6004.86; P<0.001). A similar trend was observed with mean drug costs and mean medical costs. In UC, total direct health care costs, although generally higher in patients with AESIs, were not significantly different; however, medical costs were (€1946.93 vs €971.28; P<0.001). AEs are common in patients with IBD treated with current therapies and associated with substantial health care costs. An urgent need exists for development of IBD treatments that are associated with lower rates of AEs.

Transition from pediatric to adult medical care - A survey in young persons with inflammatory bowel disease.

BackgroundTransition to adult health services is a vulnerable phase in young persons with chronic disease. We describe how young persons with inflammatory bowel disease in Germany and Austria experience care during the transitional age, focusing on differences by type of provider (pediatric vs. adult specialist, no specialist).MethodsThis was a follow up survey in patients previously registered with a pediatric IBD registry. Patients aged 15 to 25 received a postal questionnaire, including a measure of health care experience and satisfaction. Descriptive analyses were stratified by age. Sub-analyses in the 18–20 year age group compared health care experience by type of provider. Determinants of early or late transfer were examined using multinomial logistic regression.Results619 patients responded to the survey; 605 questionnaires were available for analysis. Usual age of completing transition was 18. Earlier transfer was more common with low parental SES (OR 1.8, 95% CI 0.7 to 4.6), and less common with advanced schooling (OR 0.5, 95% CI 0.2 to 1.2). Structured transition was uncommon. 48% of the respondents had not received any preceding transition advice. Overall satisfaction with IBD care was high, especially with respect to interpersonal aspects, but less so in aspects of continuity of care.ConclusionsDespite high overall patient satisfaction, relevant deficiencies in transitional care were documented. Some of these were associated with lower parental social status. Differences in health care satisfaction by type of provider (adult vs. pediatric) were small.

Regional differences in health care of patients with inflammatory bowel disease in Germany

BackgroundThe regional availability of specialized physicians is an important aspect in healthcare of patients with IBD. The association between physician density and healthcare is not yet clear. Most studies did not consider district type, which reflects population density. Our research question was, “Do specialist density and district type influence the healthcare of IBD patients in Germany?”MethodsWe combined a claims dataset from a German health insurance fund with population and physician data. Four main aspects were investigated: regular specialist visits, drug therapies, surveillance colonoscopy, and IBD-related hospitalizations. Various regression analyses were performed.ResultsThe study cohort was comprised of 21,771 individuals, including 9282 patients with Crohn disease and 12,489 patients with ulcerative colitis. Patients who were living in districts with higher specialist densities were more likely to attend specialist visits on a regular basis. No difference in the frequencies of TNF-alpha inhibitor therapies was found. However, individuals from urban areas were more likely to receive a permanent immunosuppressive therapy with continuous specialist support.ConclusionsThe results revealed that some aspects had positive effects on the probability of implementing healthcare in accordance with pathways and guidelines. No clear evidence of a general healthcare undersupply in rural areas was found.Electronic supplementary materialThe online version of this article (doi:10.1186/s13561-015-0067-1) contains supplementary material, which is available to authorized users.

Should Cost-Effectiveness Analysis Include the Cost of Consumption Activities? AN Empirical Investigation.

There has been a debate on whether cost-effectiveness analysis should consider the cost of consumption and leisure time activities when using the quality-adjusted life year as a measure of health outcome under a societal perspective. The purpose of this study was to investigate whether the effects of ill health on consumptive activities are spontaneously considered in a health state valuation exercise and how much this matters. The survey enrolled patients with inflammatory bowel disease in Germany (n = 104). Patients were randomized to explicit and no explicit instruction for the consideration of consumption and leisure effects in a time trade-off (TTO) exercise. Explicit instruction to consider non-health-related utility in TTO exercises did not influence TTO scores. However, spontaneous consideration of non-health-related utility in patients without explicit instruction (60% of respondents) led to significantly lower TTO scores. Results suggest an inclusion of consumption costs in the numerator of the cost-effectiveness ratio, at least for those respondents who spontaneously consider non-health-related utility from treatment. Results also suggest that exercises eliciting health valuations from the general public may include a description of the impact of disease on consumptive activities.

Validity, reliability, and responsiveness of the EQ-5D in inflammatory bowel disease in Germany

The EuroQol (EQ)-5D questionnaire is a generic instrument measuring health-related quality of life. Its validity, reliability, and responsiveness were assessed in a large sample of Crohn's disease (CD) and ulcerative colitis (UC) patients. The EQ-5D was completed initially (270 CD and 232 UC subjects) and after 4 weeks (447 subjects) with a transition question rating health change. Responsiveness of EQ visual analog scale (EQ-VAS) and the United Kingdom (UK-index) and German EQ-5D index (EQ-index) scores to reported changes in health was evaluated by standardized response means (SRM) and meaningful differences (MDs). EQ-VAS and EQ-index scores correlated well with disease activity indices and differed significantly between active disease and remission groups. All scores were reliable in test-retest (ICC: EQ-VAS: 0.89; UK-index: 0.76; German EQ-index: 0.72). According to SRM, EQ-VAS was more responsive for deterioration in health than for improvement in health and was more responsive than index scores. Index scores were most responsive for deterioration in health in subjects in remission and for improved health in subjects with active disease. MDs for improved health (EQ-VAS: 10.9; UK EQ-index: 0.076; German EQ-index: 0.050) and deteriorated health (EQ-VAS: -14.4; UK EQ-index: -0.109; German EQ-index: -0.067) were significant, but MD of EQ-VAS also differed significantly according to disease activity. The EQ-5D generates valid, reliable, and responsive preference-based evaluations of health in CD and UC. EQ-VAS scores were more responsive than EQ-5D index scores. Thus, small health differences that are important from the patient's perspective may not be reflected in the EQ-index.

The incidence of inflammatory bowel disease in a rural region of Southern Germany: a prospective population-based study

Although important advances in understanding the aetiology and pathogenesis of inflammatory bowel disease (IBD) have been made, many questions remain unanswered. As the most recent data available on the incidence of IBD in Germany were collected about 15 years ago, we set up a new population-based cohort to determine current incidence data for a defined region in Germany and to establish a basic cohort for prospective follow-up. All patients living in the region of Oberpfalz newly diagnosed with IBD between 1 January 2004 and 31 December 2006 were included in this study by setting up a network of reporting clinicians and general practitioners in hospitals as well as in private practices. Demographic and clinical characteristics such as age at first diagnosis, localization of the disease, extraintestinal manifestations or family history on IBD were documented. Age-adjusted incidence rates are presented with 95% Poisson confidence intervals (CIs), based on the European standard population. In total, 286 newly diagnosed patients with IBD were reported in this region, 168 patients suffering from Crohn's disease (CD), 105 patients with ulcerative colitis. Age-standardized incidence rates were 11.0/10(5) (95% CI: 9.1-11.6) for IBD, 6.6/10(5) (95% CI: 5.6-7.7) for CD and 3.9/10(5) (95% CI: 3.2-4.7) for ulcerative colitis. Peak incidences were found in the age interval of 16-24 years for both diseases, predominantly for CD. Age at first diagnosis was lower, extraintestinal manifestations and a positive family history on IBD were more common in patients with CD. The incidence rate in IBD seems to be stable in Germany as compared with previously reported data, as is the remarkable predominance of CD. Prospective follow-up studies will be based on this incidence cohort.

Cost Effectiveness of Ibandronate for the Prevention of Fractures in Inflammatory Bowel Disease-Related Osteoporosis

Osteoporosis is a frequent complication in patients with inflammatory bowel disease. Recent studies have shown bisphosphonates to considerably reduce fracture risk in patients with osteoporosis, and preventing fractures with bisphosphonates has been reported to be cost effective in older populations. However, no studies of the cost effectiveness of these agents in preventing fractures in patients with inflammatory bowel disease are available. To investigate the cost effectiveness of the bisphosphonate ibandronate combined with calcium/colecalciferol ('ibandronate') in patients with osteopenia or osteoporosis due to inflammatory bowel disease in Germany. Treatment strategies used for comparison were sodium fluoride combined with calcium/colecalciferol ('fluoride') and calcium/colecalciferol ('calcium') alone. A cost-utility analysis was conducted using data from a randomized controlled trial (RCT). Changes in bone mineral density (BMD) were adjusted and predicted for a standardized population receiving each respective treatment. A Markov model was developed, with probabilities of transition to fracture states consisting of BMD-dependent and -independent components. The BMD-dependent component was assessed using predicted change in BMD from the RCT. The independent component captured differences in bone quality and micro-architecture resulting from prevalent fractures or treatment with anti-resorptive drugs. The analysis was conducted for a population with a mean age of the RCT patients (women aged 36 years, men aged 38 years) with osteopenia (T-score about -2.0 at baseline), a population of the same age with osteoporosis (T-score of -3.0 at baseline) and for an older population (both sexes aged 65 years) with osteoporosis (T-score of -3.0). Outcomes were measured as costs per QALY gained from a societal perspective. The treatment duration in the RCT was 42 months. A 5-year period was assumed to follow, during which the treatment effects linearly declined to 0. The simulation time was 10 years. Prices for medication and treatment were presented as year 2004 values; costs and effects were discounted at 5%. To test the robustness of the results, univariate and probabilistic sensitivity analyses (Monte Carlo simulation) were conducted. The calcium strategy dominated the fluoride strategy. When the ibandronate strategy was compared with the calcium strategy, the base-case cost-effectiveness ratios (costs per QALY gained) were between euro 407 375 for an older female population with osteoporosis and euro 6 516 345 for a younger female population with osteopenia. Univariate sensitivity analyses resulted in variations between 4% of base-case results and dominance of calcium. In Monte Carlo simulations, conducted for the various populations, the probability of an ICER of ibandronate below euro 50 000 per QALY was never greater than 20.2%. The ibandronate strategy is unlikely to be considered cost effective by decision makers in men or women with characteristics of those in the target population of the RCT, or in older populations with osteoporosis.

Costs of Inflammatory Bowel Disease in Germany

Inflammatory bowel disease (IBD) is a chronic condition that afflicts young adults in their economically productive years. The goal of this study was to determine the costs of IBD in Germany from a societal perspective, using cost diaries. Members of the German Crohn's Disease and Ulcerative Colitis Association who had IBD were recruited by post, and those who agreed to participate documented their IBD-associated costs prospectively in a diary over 4 weeks. They documented their use of healthcare facilities, medications, sick leave and out-of-pocket expenditures, as well as general demographic information, the status and history of their IBD, and long-term disability. Item costs were calculated according to national sources. Cost data were calculated using non-parametric bootstrapping and presented as mean costs (year 2004) over 4 weeks. The cost diaries were returned by 483 subjects (Crohn's disease: n = 241, ulcerative colitis: n = 242) with a mean age of 42 years and an average disease duration of 13 years (SD +/- 8.09). The cost diaries were regarded as 'easy to complete' by 89% of participants. The mean 4-week costs per subject were 1,425 Euros(95% CI 1201, 1689) for Crohn's disease and 1,015 Euros(95% CI 832, 1258) for ulcerative colitis. Of the total costs for Crohn's disease, 64% were due to indirect costs such as early retirement or sick leave and 32% were due to direct medical costs. In contrast, of the total costs for ulcerative colitis, 41% were due to direct medical costs and 54% to indirect costs. This is the first comprehensive cost study for Crohn's disease and ulcerative colitis in Germany. The most important economic factors that influenced the cost profiles of both diseases were the long-term productivity losses due to an ongoing inability to work and the cost of medications. Results indicate significant cost differences between Crohn's disease and ulcerative colitis. This data provides initial cost estimates that can be analysed further with respect to cost determinants and disease-specific costs in the future.
