Purpose: The purpose of this study is to build a risk prediction model for pediatric Crohn's disease to predict outcomes of sustained remission/flare, surgery, and hospitalization using data from ICN Registry and PCORnet.

Specific Aims:

  1. Leveraging longitudinal data from ICN registry and PCORnet, and previously developed methods in assessing and stratifying disease activities, this study proposes to apply data analytics and visualization to facilitate efficient decision support for personalized care and risk prediction in pediatric Crohn’s disease. We aim to develop a machine-learning based clinical pathway learning algorithm for pediatric Crohn’s disease that predicts for 3 outcomes of interests: (1) sustained remission/flare, (2) surgery, and (3) hospitalization. Stratifying patients by their risk levels using PCDAI and sPCDAI, we will infer the common disease progression trajectories that are unique to each patient subpopulation from data, which we further use for prediction of future patient states.

Purpose: The purpose of this study is to evaluate the perspectives of pediatric and adult gastroenterologists on the clinical utility and feasibility of the Pediatric IBD Medical Transfer Summary (PIBD-MTS) tool, which is aimed to synopsize the salient aspects of a young adult's prior pediatric medical course, as a tool to be shared with the receiving adult provider in the transfer of care process.

Specific Aims:

The ICN Transition and Transfer Committee developed the PIBD-MTS as a collaboration amongst pediatric and gastroenterologists, psychologists, young adults of PAC, and parents of PWG. The summary has undergone multiple revisions, including adaption for electronic medical records. Feedback from both pediatric and adult gastroenterologists has been largely qualitative, with infrequent patient-specific feedback.

  • We will assess pediatric provider satisfaction with the PIBD-MTS, including time spent for completion and content
  • We will assess adult provider satisfaction with the PIBD-MTS, including time spent reviewing information, completeness, and quality of information related to IBD care.

Purpose: The purpose of this study is to determine if ulcerative colitis pediatric patients can maintain remission on a 1.6 mg vs. 2.4 mg weight-based dosing of mesalamine DR (Delzicol).

Specific Aims:

Using adult studies as a guide, we aim to compare two weight-based, parallel arms of 2.4 mg vs 1.6 mg in maintaining UC remission over 26 weeks using the modified Mayo Score and other Mayo score derivatives.  Pediatric patients will be aged 5-17 and must have been on a stable dose of mesalamine or 5 ASA equivalent for 30 days prior to enrollment and must be in remission for 30 days.  Dosing choices are taken from adult maintenance mesalamine dosing.

Inflammatory bowel disease (IBD) is a chronic immune mediated condition that impacts not only the physical health of patients but also their psychosocial wellbeing and quality of life. Multidisciplinary care is advised in the care of children and adolescents with IBD. Models of multidisciplinary care for pediatric IBD have been described in the literature but real-world access to multidisciplinary care as well as provider attitudes and perceived barriers and facilitators to it remain largely unknown. Michel et al described the described the approach to the pediatric IBD medical home at our IBD center (Nationwide Children's Hospital) in a study published in 2022 (Michel et al. 2022).

Our center has access to several resources given the size and scope of our institution but we recognize that these resources are not available at all centers. In a survey study by Winnick et al, ICN centers were surveyed to assess their access to psychosocial support services for IBD patients. The study found that the majority of centers had access to psychosocial support, however most of these providers were not dedicated exclusively to IBD and they were often only available during limited hours (Winnick et al. 2023). This study would be helpful to assess what common barriers in access to this type of care across ICN centers in the US, while acknowledging that ICN centers do not encompass all centers providing pediatric IBD care. Analyzing this data will allow pediatric IBD centers to assess care gaps and advocate for improved care.

Aims & Hypothesis: This study aims to understand availability and access to multidisciplinary care for children with IBD across US ICN centers. It also aims to explore provider attitudes, barriers, and facilitators of care. We hypothesize that access to multidisciplinary care will vary widely across US ICN centers. Providers will feel positively toward multidisciplinary care for children with IBD, but identify multiple personnel, local, and system-level barriers to care access and delivery.

Overall Study Question: Evaluate variation in prescribing habits of IV anti-TNF therapies across the pediatric IBD community. Evaluate the safety and efficacy of non-medical switches from the originator to a biosimilar

Specific Aims:

  1. To evaluate infliximab use over time for patients who are anti-TNF naïve, to determine if biosimilar use is increasing nationally, variation amongst practices, geographic regions, by commercial vs Medicaid insurance, and race.
  2. To evaluate long-term clinical outcomes of pediatric patients initiated on an infliximab biosimilars vs the originator.
  3. Evaluate how often switching from the originator to a biosimilar are occurring within the ICN Network.  Determine if non-medical switching adversely affects clinical outcomes in pediatric IBD patients including the impact upon clinical remission in addition to anti-TNF drug and antibody levels. Evaluate how often patients are switching back to the originator or to a different therapy class.

Pediatric patients with IBD are known to have higher rates of psychosocial concerns than peers without IBD, including body image complexities and disordered eating behaviors (Claytor et al., 2020; David et al., 2017; David et al.,2021). While there is emerging understanding of protective and risk factors amongst patients with IBD regarding their relationships with their bodies and food including negative weight-based interactions, there is not yet an understanding of how pediatric IBD medical providers perceive patients' weights and body sizes and if the weight stigma that has been identified in adults with IBD exists (Guo et al., 2020) in pediatrics. Future interventions to optimize psychosocial health and reduce body image and disordered eating risk in pediatric IBD may be limited in impact without exploring how, if at all, weight stigma beliefs amongst medical providers contributes to body image and disordered eating risk. Stated differently, there are likely provider-related variables that serve as protective or risk factors for pediatric IBD patients' body image and relationship with food. The foundational work to understand if weight stigma is present amongst pediatric IBD medical providers has not yet been completed. This work is critically needed for future studies to understand how weight stigma may impact patients' psychosocial health and care and to inform future patient, provider, and system levels interventions.

Overall Study Question: How does the family and patient engagement process impact which advocates become centrally involved in the Collaborative Learning Health Systems operations?

Specific Aims: We will use qualitative interviewing methods to understand the experiences and practices of different groups involved in the patient engagement process within Collaborative Learning Health Systems. We have developed interview guides for each stakeholder group (patients/parents, healthcare providers, and engagement teams). These interview guides ask a range of questions to understand organizational processes, personal experiences, and professional experiences in order to elicit mechanisms of patient engagement and barriers and facilitators in patient engagement processes.

Purpose: Social Determinants of Health (SDoH) has become an increasingly relevant and highlighted topic in healthcare, with the consensus among public health organizations being that SDoH are an important factor in health and impacting patient care. However, there has been limited guidance and recommendation into how to practically implement approaches to integrating SDoH screening into clinical care. For this reason we seek to directly evaluate the perceptions around SDoH screening among healthcare providers and investigate what key elements and barriers are common within SDoH screening practices.

Aims & Hypothesis: Our specific aims are to investigate the key steps and/or barriers involved in administering Social
Determinants of Health (SDoH) screening as well as assess differences in providers' perspective on SDoH screenings
and understand what factors may affect these perspectives. Certain factors, including knowledge and focus on Social Determinants of Health (SDoH), are more likely to result in having an established SDoH screening and being knowledgable about the screening process.

Overall Study Question: Initial data review of the ICN registry has found that since 2014, nearly 600 patients have undergone colectomy. We suspect that deeper review of this patient population is likely to provide insight for clinical care in addition to identifying variation in care delivery across the ICN network, thus making this patient cohort important for further data analysis. Ultimately, this deeper evaluation could provide insight toward improving patient outcomes.

Specific Aims: We would like to review clinical variables including BMI prior to colectomy, medication exposures prior to colectomy, time from diagnosis to colectomy, incidence rates of colectomy among patients newly diagnosed with UC in ICN database.
We also suspect there could be variation in colectomy rates or treatment approaches across the collaborative between academic vs nonacademic center, regional variation, public vs commercial insurance, and possible trends of biological treatment prior to colectomy.

Purpose: Crohn's disease causes chronic bowel inflammation which can lead to strictures, fistulas, growth stunting, and other complications if inadequately controlled. We typically monitor inflammation via symptoms and laboratory monitoring. In the absence of symptoms, elevated inflammatory markers (erythrocyte sedimentation rates, c-reactive protein) is sometimes referred to as "silent Crohn's disease". It is unclear how often silent Crohn's disease occurs, or what the implications are. There is some evidence in adults that silent Crohn's disease is associated with increased risk of hospitalization. This has not been evaluated in children.

Specific Aims:

1. Determine the frequency of silent Crohn's disease in children with Crohn's disease in the ImproveCareNow
Network registry.
2. Determine the association between silent Crohn's disease and risk of disease-related complications including
strictures, fistulas, perianal disease, and short stature.

Purpose: Although biologic therapies, such as anti-TNF, have improved outcomes, up to 30% have no initial response (primary nonresponders) while treatment responders frequently lose response over the following years. There is a crucial need to individualize Crohn’s disease therapy by utilizing a patients’ immune profile to both predict and monitor therapeutic responses over time to reduce costs associated with poorly controlled Crohn’s. Our grant proposal is centered on the primary hypothesis that proactive monitoring of neutrophil CD64, soluble CD64 and infliximab trough concentrations at the end of induction will provide clinicians with treatment targets in order to improve rates of secondary nonresponse.

Primary/Secondary Outcomes:

  • Primary: Neutrophil CD64 index and soluble CD64 and infliximab response.
  • Secondary: Neutrophil CD64 index, soluble CD64 and infliximab concentration.

Purpose: The investigational product, Budesonide Extended-Release tablet, is a glucocorticosteroid that is administered orally. UCERIS® (budesonide) extended release 9mg tablets was approved for adults in 2013 for the induction of remission in adult patients with active, mild-to-moderate UC, and may provide a useful therapeutic option for pediatric patients with UC.
It's an advantageous therapy because it has a hard enteric capsule that inhibits systemic absorption as it travels through the patient's body to the site of disease activity, where it will be 90% absorbed and delivered along the inflamed areas of the colon, thus making it possible to be used as a long-term therapy. Typical steroid therapies risk systemic exposure in the body and are not a long-term solution for children because they disrupt hormones, growth, etc. This medicine is also an alternative to costly biologic therapies. Various formulations of budesonide are approved in the US for therapeutic areas including allergic rhinitis, asthma, and inflammatory bowel disease (IBD; including both Crohn's disease [CD] and Ulcerative colitis (UC).

Aims & Hypothesis: This study aims to put inflammation into remission without the cost of biologics or risk of other systemic steroids. The primary objective of this study is to evaluate the efficacy and safety of a low and a high dose of budesonide extended-release tablets in pediatric subjects with active, mild to moderate UC. The secondary objective is to evaluate the pharmacokinetics of budesonide after oral administration of budesonide extended-release tablets in pediatric subjects with active, mild to moderate UC. The primary efficacy endpoint is the proportion of subjects who achieve clinical remission at Day 56, defined as a total Mayo score of ≤ 1 with subscores of 0 for both rectal bleeding and stool frequency, and a subscore of ≤ 1 for endoscopy.

Purpose: Crohn’s disease causes fistulas, which are abnormal openings from the bowel to adjacent structures such as the skin, bladder, genitals, or to other loops of bowel.  Fistulas frequently lead to serious and sometimes debilitating complications. 

Fistulas have a major negative impact on quality of life of children and their caregivers and are highly distressing.  Fistulas can cause many complications including fecal incontinence, infertility, chronic draining wounds, abscesses, and severe infections of the bladder, kidneys, uterus, or other internal structures. Fistulas are difficult to treat, requiring expensive medications and surgery, and treatments are often not effective. Strategies are needed to prevent fistulas from developing in the first place.

This study is designed to answer several important questions:

  • What are the characteristics of children who at the greatest risk for developing fistulas? 
  • Does early selection of therapy alter the risk for fistulas among children? 
  • Does the risk of fistula among children change with the duration of disease?

Primary Outcomes: 

  • Developing perianal fistula
  • Time to perianal fistula development

Secondary Outcomes:

  • Medication use
  • Surgery

Purpose: Very early-onset inflammatory bowel disease (VEO-IBD) presents in children less than 6 years of age. These patients have more extensive, progressive and medically refractory disease making it phenotypically distinct from older-onset pediatric and adult IBD.

The incidence of pediatric IBD is increasing rapidly but there is no specific data for the US population. Given the paucity of information, our objective was to determine the prevalence of VEO-IBD within the ImproveCareNow (ICN) Network registry, which accounts for more than 50% of all pediatric IBD patients in the US.

Primary Outcome: Our primary outcomes are frequency of clinical remission in the VEO-IBD population and time to clinical remission. Clinical remission will be defined by normal physician global assessment (PGA), PCDAI, PUCAI, ESR or CRP.

Secondary Outcome: Our secondary outcomes will be frequency of and time to surgery (specifically, colectomy or creation of ileostomy or colostomy) and frequency of sustained corticosteroid free remission, one of the major outcomes tracked by the ImproveCareNow Network.

Study Period: June 2020-July 2021

Purpose: The primary objective of this study is to evaluate the clinical effectiveness of ustekinumab by determining the clinical remission rate in pediatric patients with moderately to  severely active Crohn’s Disease (CD) in the ICN registry who were treated with ustekinumab.

Primary Outcome: This study will generate knowledge about the use of ustekinumab in the management of pediatric Crohn’s Disease. The results of this study will be included as part of a Janssen submission to the FDA for the approval of the use of ustekinumab in pediatric patients, as they plan a phase 3 clinical trial of ustekinumab. In addition, the inclusion of RWE from ICN could help facilitate the approval of ustekinumab and other  new  drugs  for  IBD,  making  new  IBD treatments accessible  to  pediatric  patients sooner, enabling better outcomes for our patients. If the ICN-Janssen REALITI Study is successful, other new IBD drugs could be studied in a similar way, having a major impact on the health of our patients as well as on the sustainability of ICN.

Funding Source: Janssen has provided funding to ICN to perform this study; however, it is important to note that this  is  an  observational study with  a  retrospective  chart  review  and not an interventional study.

Study Period: The study will take approximately 9 to 18 months to complete from implementation to publication.

Recruitment Status: All eligible patients have been identified via the ICN  Registry, the 72 ICN centers with eligible patients have been invited to participate.

Purpose: The purpose of this study is to identify the risk factors that are most important in developing severe UC (PUCAI >65 and/or colectomy), so that they can be mitigated and more intensive therapy can be initiated earlier in order to avoid surgery.

Specific Aims:

  • Identify risk factors for colectomy and severe disease in UC. Search ICN database to identify patients with UC who required colectomy or had PUCAI>65. Identify top 10 risk factors patients had in common. Compare and contrast risk factors to a case control group of UC patients in the ICN database, marked by physician global assessment “quiescent” and in remission. Check for statistically significant differences among the risk factors between the two groups.
  • Identify the medications patients used in each group. Assess statistically if certain medications were used or not by patients who had colectomy or PUCAI > 65.

Purpose: To determine whether race is associated with delay in diagnosis, patterns of follow-up care, trust in the healthcare system, and key outcomes including use of biologics, steroids, hospitalization and surgery.
We will also test whether socioeconomic status, frequency of follow-up and trust in the healthcare system confound or mediate associations between race and IBD outcomes.

Primary Outcome: Each outcome is selected to understand differences in treatment patterns that are likely to impact the course of IBD, are major events that signify a change in disease course, and/or have been associated with significant adverse outcomes. The following outcomes will be compared between the study groups. They are broken into two categories of outcomes: medication treatment patterns and clinical outcomes.

The selected medication for IBD depends primarily on the severity of active disease, the patient's tolerance, observed clinical response, and cost. Timely access to selected medications is critical to prevent complications from untreated disease such as strictures, infection, or need for surgical intervention. Of the approximately 13 biologics/small molecules approved for adult IBD, only 2 are currently approved in children: infliximab and adalimumab.

Pediatric patients often receive non-FDA approved biologics/small molecules with prior authorization after failing other FDA-approved medications or if they present with severe disease that necessitates urgent use of a non-FDA approved medication.


  1. Identify the number/ percentage of patients who were exposed to a biologic/small molecule without FDA approval
  2. Identify the number/ percentage of patients who were exposed to specific number of biologic/small molecule without FDA approval (i.e. # exposed to 1 drug, # exposed to 2 drugs, etc.)
  3. Identify the average age of first exposure to non-FDA approved biologic/small molecule
  4. Identify the time from diagnosis toto first exposure to non-FDA approved biologic/small molecule (will consider time to second, third exposure as well)
  5. Identify variations, if any, of non-FDA approved biologic/small molecule medication use within gender and race/ethnicity subgroups

Purpose: Uveitis has long been recognized as an extraintestinal manifestation of inflammatory bowel disease. The prevalence of uveitis in the pediatric IBD population has only been studied in small groups of IBD patients in single-center studies. Evaluating the prevalence of uveitis in the ImproveCareNow database will allow us to gain a much better appreciation of the prevalence of uveitis in the pediatric IBD population and learn more about possible risk factors.

Primary/Secondary Outcomes:

  • Primary Outcome: Assess the prevalence of uveitis in the pediatric IBD population
  • Secondary Outcome: Find associated risk factors for uveitis in the pediatric IBD population

Study Period: Patients enrolled between 2006 and 2016

Recruitment Status: This study makes use of existing data in the ICN registry. No patient recruitment at this time.
