RESUMO

BACKGROUND: Multiple biologics are available to treat inflammatory bowel disease (IBD), which can either be administered subcutaneously or intravenously. The factors that determine patients' preferences for SC/IV administration in IBD are largely unknown. This study aims to elucidate how IBD patients trade off between medications' route of administration and other medication characteristics and to understand what drives patients' preferences. METHODS: We employed a mixed methods design using data from a prior quantitative conjoint analysis survey and a series of 22 qualitative interviews. We quantitatively assessed individual patients' preferences for subcutaneous (SC) or intravenous (IV) medications based on the part-worth utilities derived from the conjoint analysis and identified predictors for these preferences. We used a qualitative analysis to identify key themes surrounding patients' preferences in the interview data. RESULTS: Of 1,077 survey participants, 49% preferred an SC medication every 2 weeks, whereas 51% preferred an IV medication every 8 weeks. More people preferred SC at reduced administration frequencies, whereas less people preferred SC at the expense of lower efficacy or higher side-effects rates. Prior experience with SC/IV was the strongest predictor for patients' preferences. Qualitatively, we obtained in-depth insights in the perceived advantages and disadvantages of SC and IV medications and in patients' preconceived ideas. CONCLUSION: While prior SC/IV exposure was a strong predictor for SC/IV preferences, patients' preferences largely are determined by a variety of other personal factors. The themes we identified could help guide clinicians when discussing therapeutic options with their patients and support shared decision-making.

RESUMO

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk of infections, bone fractures, and skin cancers. OBJECTIVE: We developed preventive health videos using a patient-centered approach and tested their impact on preventive health uptake. METHODS: Five animated videos explaining preventive health recommendations in IBD were iteratively developed with patient-centered focus groups and interviews. A randomized controlled trial was then conducted in a web-based IBD cohort to test the impact of video- versus text-based educational interventions. The primary outcome was receipt of the influenza vaccine. Secondary outcomes included intention to receive other preventive health services. RESULTS: Five animated videos were developed with patient input. A total of 1056 patients with IBD were then randomized to receive the video (n=511) or text-only (n=545) interventions; 55% (281/511) of the video group and 57% (311/545) of the text-only group had received their influenza vaccine in the prior year. Immediately after the intervention, 73% (502/683) of patients reported their intention to receive the vaccine, with no difference by the type of intervention (75%, 231/307, for the video group and 72%, 271/376, for the text-only group). The proportion of patients who actually received the influenza vaccine after the intervention also did not differ by messaging type (P=.07). The strongest predictor of both intention to receive and actual receipt of the influenza vaccine was prior influenza vaccination. Older age was also associated with a higher likelihood of the intention to receive (age 36-75 years relative to 18-35 years; P=.006) and actual receipt (age >75 years relative to 18-35 years; P=.05) of the influenza vaccine. CONCLUSIONS: The proportion of patients receiving the influenza vaccine was high in both groups, but there was no difference in receipt of or in the intention to receive preventive health recommendations by type of messaging. Notably, a portion of patients in both groups had intended to be vaccinated but did not ultimately receive the vaccine. Further evaluation of patient-education strategies is warranted to improve preventive health uptake among patients with IBD.

RESUMO

INTRODUCTION: To broadly disseminate 5 user-centered educational videos for patients with inflammatory bowel disease and their family and friends on social media. METHODS: Relevant social media users were iteratively identified based on their online behavior. For each video, 2 different accompanying texts were tested. RESULTS: We reached 4.2 million social media users of whom 320,302 watched at least 50% of the video. A short description resulted in higher view rates than posing an open-ended question. DISCUSSION: We showed the feasibility of large-scale dissemination of health-related educational videos through social media. Our findings can inform future online dissemination approaches of educational content.

RESUMO

INTRODUCTION: To support shared decision-making (SDM) between patients and providers surrounding biologic treatments, we created IBD&me ( ibdandme.org )-a freely available, unbranded, interactive decision aid. We performed a multicenter comparative effectiveness trial comparing the impact of IBD&me on SDM vs a biologics fact sheet developed by the Crohn's & Colitis Foundation. METHODS: We enrolled patients with inflammatory bowel disease (IBD) being seen at a clinic within IBD Qorus-a multicenter adult IBD learning health system-between March 5, 2019, and May 14, 2021. Eligible patients included those with recent IBD-related symptoms who reported that they wanted to discuss biologics with their provider during their upcoming visit. Patients were randomized 1:1 using stratified block randomization and received an e-mail 1 week before their visit inviting them to review either IBD&me or a fact sheet. The primary outcome was patient perception of SDM as measured by the 9-Item SDM Questionnaire (0-100 scale; higher = better); the Student t test was used to compare outcomes between arms. RESULTS: Overall, 152 patients were randomized (biologics fact sheet 75, IBD&me 77); most patients had Crohn's disease (66.4%) and were biologic-experienced (82.9%). No differences were seen between groups regarding SDM (fact sheet 72.6 ± 25.6, IBD&me 75.0 ± 20.8; P = .57). Most patients stated they would be likely to recommend the fact sheet (79.6%) or IBD&me (84.9%; P = .48) to another patient with IBD. DISCUSSION: No differences in outcomes were seen between IBD&me and the biologics fact sheet in this comparative effectiveness study; patients reported high satisfaction with both resources. Further study, particularly among biologic naïve patients, is needed to determine the utility of interactive components to IBD decision aids.

RESUMO

BACKGROUND: Inflammatory Bowel Diseases with its complexity and heterogeneity could benefit from the increased application of Artificial Intelligence in clinical management. AIM: To accurately predict adverse outcomes in patients with IBD using advanced computational models in a nationally representative dataset for potential use in clinical practice. METHODS: We built a training model cohort and validated our result in a separate cohort. We used LASSO and Ridge regressions, Support Vector Machines, Random Forests and Neural Networks to balance between complexity and interpretability and analyzed their relative performances and reported the strongest predictors to the respective models. The participants in our study were patients with IBD selected from The OptumLabs® Data Warehouse (OLDW), a longitudinal, real-world data asset with de-identified administrative claims and electronic health record (EHR) data. RESULTS: We included 72,178 and 69,165 patients in the training and validation set, respectively. In total, 4.1% of patients in the validation set were hospitalized, 2.9% needed IBD-related surgeries, 17% used long-term steroids and 13% of patients were initiated with biological therapy. Of the AI models we tested, the Random Forest and LASSO resulted in high accuracies (AUCs 0.70-0.92). Our artificial neural network performed similarly well in most of the models (AUCs 0.61-0.90). CONCLUSIONS: This study demonstrates feasibility of accurately predicting adverse outcomes using complex and novel AI models on large longitudinal data sets of patients with IBD. These models could be applied for risk stratification and implementation of preemptive measures to avoid adverse outcomes in a clinical setting.

RESUMO

INTRODUCTION: A multicenter adult inflammatory bowel disease learning health system (IBD Qorus) implemented clinical care process changes for reducing unplanned emergency department visits and hospitalizations using a Breakthrough Series Collaborative approach. METHODS: Using Markov decision models, we determined the health economic impact of participating in the Collaborative from the third-party payer perspective. RESULTS: Across all 23 sites, participation in the Collaborative was associated with lower annual costs by an average of $2,528 ± $233 per patient when compared with the baseline period. DISCUSSION: Implementing clinical care process changes using a Collaborative approach was associated with overall cost savings. Future work should examine which specific interventions are most effective and whether such cost savings are sustainable.

RESUMO

PURPOSE: Inflammatory bowel disease (IBD) patients experience diverse symptoms and the impact of these different symptoms varies substantially. Current disease activity measures do not account for the relative importance of the different symptoms and severity levels. In this study, we aimed to quantify the relative importance of different symptoms for IBD patients and to develop a patient preference-weighted symptom (PWS) score to assess symptom burden in IBD. METHODS: We performed a choice-based conjoint analysis (CBCA) survey with 129 IBD patients to estimate the relative importance of four common IBD symptoms: stool frequency, abdominal pain, blood in stools, and urgency. We then developed the PWS score using the preferences obtained from the CBCA, which we validated against existing measures. RESULTS: CBCA revealed that urgency was the most important symptom to patients, followed by abdominal pain and blood in stools. Urgency associated with incontinence received particularly high scores and was perceived to be more than 3 times as important as urgency without incontinence. Our results confirmed that different symptoms are not equally bothersome, and we showed that the relation between symptom-level and importance is not linear. The PWS score, which we developed using these estimates was highly correlated with existing disease activity measures. CONCLUSIONS: We quantified the relative importance of four common IBD symptoms and developed the PWS score for IBD, which takes the relative importance of different symptoms and symptom-levels into account. The PWS score can be used to obtain a patient-centered assessment of symptom burden.

RESUMO

PURPOSE: Patients with inflammatory bowel diseases (IBD) experience a variety of symptoms and limitations due to their condition. While many outcome measures are available to assess IBD symptom level and disease activity, individual patients' preferences are usually not accounted for. Individualized outcome measures allow individual patients to select and weigh outcomes based on their relative importance, and have been developed in other medical disciplines. In this study, we explored IBD patients' perspectives on different strategies to prioritize IBD-specific health outcomes. METHODS: Existing individualized measures were modified for relevance to IBD patients. We performed six focus groups, in which patients were asked to rate and weigh these measures in a series of exercises and to discuss the pros and cons of five different prioritization methods (Likert scale, ranking, selecting outcomes, distribute points, and using a rotating disk) using a semi-structured approach. A thematic analysis revealed key themes in the data. RESULTS: Patients' thoughts could be grouped into four key themes with 2-4 subthemes each: (1) prioritizing outcomes; (2) differences between methods; (3) outcomes to include; and (4) practical use. Overall, it was challenging for many patients to prioritize outcomes. Among the different prioritization methods, the rotating disk was perceived as the most intuitive. Patients anticipated that this visualization would also help them communicate with their physician. CONCLUSION: In a series of focus groups, a visual rotating disk was found to be an intuitive and holistic way to elicit the relative importance of different outcomes for individual IBD patients.

RESUMO

BACKGROUND: Caregiver burden is the emotional, physical, practical, and/or financial burden associated with taking care of a patient with a chronic condition. Limited literature on caregiver burden in Inflammatory Bowel Diseases (IBD) has accounted for some predictors, but its effect on work productivity (absenteeism and presenteeism) is unknown. METHODS: In a prospective study, patients and their respective caregivers were surveyed from November 2015 until July 2017. Data on demographics, work productivity, quality of life, disease activity, caregiver burden and productivity were collected. The burden on caregivers was assessed and associations between caregiver productivity and caregiver burden were analyzed. Additionally, predictors for caregiver burden were identified. RESULTS: One hundred two IBD patients and their respective caregiver were included. In total, 39% of IBD caregivers experienced burden. Caregivers with burden experienced significantly more absenteeism and presenteeism (65 and 85% respectively). Furthermore, 51% of caregivers felt that they should be doing more for their care recipient and felt they could do a better job at caregiving. Predictors of burden included race/ethnicity, history of fistulas, diagnosis of ulcerative colitis, higher caregiver education, and hours spent caregiving. CONCLUSION: Caregivers with burden had significantly more productivity decrease compared to those without burden. Additionally, the majority of caregivers feel they should be providing more and better care for their recipients. The development of strategies to address caregiver's distress and perceived burden when caring for IBD patients is warranted.

RESUMO

BACKGROUND: Long length of stays (LOS) in emergency departments (ED) negatively affect quality of care. Ordering of inappropriate diagnostic tests contributes to long LOS and reduces quality of care. One strategy to change practice patterns is to use performance feedback dashboards for physicians. While this strategy has proven to be successful in multiple settings, the most effective ways to deliver such interventions remain unknown. Involving end-users in the process is likely important for a successful design and implementation of a performance dashboard within a specific workplace culture. This mixed methods study aimed to develop design requirements for an ED performance dashboard and to understand the role of culture and social networks in the adoption process. METHODS: We performed 13 semi-structured interviews with attending physicians in different roles within a single public ED in the U.S. to get an in-depth understanding of physicians' needs and concerns. Principles of human-centered design were used to translate these interviews into design requirements and to iteratively develop a front-end performance feedback dashboard. Pre- and post- surveys were used to evaluate the effect of the dashboard on physicians' motivation and to measure their perception of the usefulness of the dashboard. Data on the ED culture and underlying social network were collected. Outcomes were compared between physicians involved in the human-centered design process, those with exposure to the design process through the ED social network, and those with limited exposure. RESULTS: Key design requirements obtained from the interviews were ease of access, drilldown functionality, customization, and a visual data display including monthly time-trends and blinded peer-comparisons. Identified barriers included concerns about unintended consequences and the veracity of underlying data. The surveys revealed that the ED culture and social network are associated with reported usefulness of the dashboard. Additionally, physicians' motivation was differentially affected by the dashboard based on their position in the social network. CONCLUSIONS: This study demonstrates the feasibility of designing a performance feedback dashboard using a human-centered design approach in the ED setting. Additionally, we show preliminary evidence that the culture and underlying social network are of key importance for successful adoption of a dashboard.

RESUMO

OBJECTIVE: Inflammatory Bowel Disease (IBD) is an inflammatory disorder of the gastrointestinal tract that can necessitate hospitalization and the use of expensive biologics. Models predicting these interventions may improve patient quality of life and reduce expenditures. MATERIALS AND METHODS: We used insurance claims from 2011 to 2013 to predict IBD-related hospitalizations and the initiation of biologics. We derived and optimized our model from a 2011 training set of 7771 members, predicting their outcomes the following year. The best-performing model was then applied to a 2012 validation set of 7450 members to predict their outcomes in 2013. RESULTS: Our models predicted both IBD-related hospitalizations and the initiation of biologics, with average positive predictive values of 17% and 11%, respectively - each a 200% improvement over chance. Further, when we used topic modeling to identify four member subpopulations, the positive predictive value of predicting hospitalization increased to 20%. DISCUSSION: We show that our hospitalization model, in concert with a mildly-effective interventional treatment plan for members identified as high-risk, may both improve patient outcomes and reduce insurance expenditures. CONCLUSION: The success of our approach provides a roadmap for how claims data can complement traditional medical decision making with personalized, data-driven predictive medicine.

RESUMO

PURPOSE: Value-based healthcare is an upcoming field. The core idea is to evaluate care based on achieved outcomes divided by the costs. Unfortunately, the optimal way to evaluate outcomes is ill-defined. In this study, we aim to develop a single, preference based, outcome metric, which can be used to quantify overall health value in inflammatory bowel disease (IBD). METHODS: IBD patients filled out a choice-based conjoint (CBC) questionnaire in which patients chose preferable outcome scenarios with different levels of disease control (DC), quality of life (QoL), and productivity (Pr). A CBC analysis was performed to estimate the relative value of DC, QoL, and Pr. A patient-centered composite score was developed which was weighted based on the stated preferences. RESULTS: We included 210 IBD patients. Large differences in stated preferences were observed. Increases from low to intermediate outcome levels were valued more than increases from intermediate to high outcome levels. Overall, QoL was more important to patients than DC or Pr. Individual outcome scores were calculated based on the stated preferences. This score was significantly different from a score not weighted based on patient preferences in patients with active disease. CONCLUSIONS: We showed the feasibility of creating a single outcome metric in IBD which incorporates patients' values using a CBC. Because this metric changes significantly when weighted according to patients' values, we propose that success in healthcare should be measured accordingly.

RESUMO

BACKGROUND & AIMS: Mobile health technologies are advancing rapidly as smartphone use increases. Patients with inflammatory bowel disease (IBD) might be managed remotely through smartphone applications, but no tools are yet available. We tested the ability of an IBD monitoring tool, which can be used with mobile technologies, to assess disease activity in patients with Crohn's disease (CD) or ulcerative colitis (UC). METHODS: We performed a prospective observational study to develop and validate a mobile health index for CD and UC, which monitors IBD disease activity using patient-reported outcomes. We collected data from disease-specific questionnaires completed by 110 patients with CD and 109 with UC who visited the University of California, Los Angeles, Center for IBD from May 2013 through January 2014. Patient-reported outcomes were compared with clinical disease activity index scores to identify factors associated with disease activity. Index scores were validated in 301 patients with CD and 265 with UC who visited 3 tertiary IBD referral centers (in California or Europe) from April 2014 through March 2015. RESULTS: We assessed activity of CD based on liquid stool frequency, abdominal pain, patient well-being, and patient-assessed disease control, and activity of UC based on stool frequency, abdominal pain, rectal bleeding, and patient-assessed disease control. The indices identified clinical disease activity with area under the receiver operating characteristic curve values of 0.90 in patients with CD and 0.91 in patients with UC. They identified endoscopic activity with area under the receiver operating characteristic values of 0.63 in patients with CD and 0.82 in patients with UC. Both scoring systems responded to changes in disease activity (P < .003). The intraclass correlation coefficient for test-retest reliability was 0.94 for CD and for UC. CONCLUSIONS: We developed and validated a scoring system to monitor disease activity in patients with CD and UC that can be used with mobile technologies. The indices identified clinical disease activity with area under the receiver operating characteristic curve values of 0.9 or higher in patients with CD or UC, and endoscopic activity in patients with UC but not CD.

RESUMO

BACKGROUND & AIMS: Persistent activation of the inflammatory response contributes to the development of inflammatory bowel diseases, which increase the risk of colorectal cancer. We aimed to identify microRNAs that regulate inflammation during the development of ulcerative colitis (UC) and progression to colitis-associated colon cancer (CAC). METHODS: We performed a quantitative polymerase chain reaction analysis to measure microRNAs in 401 colon specimens from patients with UC, Crohn's disease, irritable bowel syndrome, sporadic colorectal cancer, or CAC, as well as subjects without these disorders (controls); levels were correlated with clinical features and disease activity of patients. Colitis was induced in mice by administration of dextran sodium sulfate (DSS), and carcinogenesis was induced by addition of azoxymethane; some mice also were given an inhibitor of microRNA214 (miR214). RESULTS: A high-throughput functional screen of the human microRNAome found that miR214 regulated the activity of nuclear factor-κB. Higher levels of miR214 were detected in colon tissues from patients with active UC or CAC than from patients with other disorders or controls and correlated with disease progression. Bioinformatic and genome-wide profile analyses showed that miR214 activates an inflammatory response and is amplified through a feedback loop circuit mediated by phosphatase and tensin homolog (PTEN) and PDZ and LIM domain 2 (PDLIM2). Interleukin-6 induced signal transducer and activator of transcription 3 (STAT3)-mediated transcription of miR214. A miR214 chemical inhibitor blocked this circuit and reduced the severity of DSS-induced colitis in mice, as well as the number and size of tumors that formed in mice given azoxymethane and DSS. In fresh colonic biopsy specimens from patients with active UC, the miR214 inhibitor reduced inflammation by increasing levels of PDLIM2 and PTEN. CONCLUSIONS: Interleukin-6 up-regulates STAT3-mediated transcription of miR214 in colon tissues, which reduces levels of PDLIM2 and PTEN, increases phosphorylation of AKT, and activates nuclear factor-κB. The activity of this circuit correlates with disease activity in patients with UC and progression to colorectal cancer.

RESUMO

PURPOSE OF REVIEW: Stem cell therapy has emerged as a promising therapeutic strategy for inflammatory bowel diseases (IBDs). Currently, stem cell therapy is not part of the standard of care and is usually only performed as a part of clinical trials. In this review, clinical results, proposed underlying mechanisms, and future research directions will be discussed. RECENT FINDINGS: Administration of mesenchymal stem cells (MSCs) and hematopoietic stem cells (HSCs) has been evaluated for IBD treatment over the past years. MSC therapy is being explored as a treatment option for fistulizing Crohn's disease and for luminal Crohn's disease. It is shown to be well tolerated, but results on efficacy are inconsistent. HSC transplantation seems to be very effective, but serious adverse events are common. Therefore, future research should focus on improving efficacy of MSC therapy, and on improvement of safety of HSC therapy. SUMMARY: Both MSC and HSC therapy offer clinical potential, but currently are not routinely used for IBD treatment. MSC therapy seems well tolerated but results on efficacy are conflicting. HSC transplantation is shown to be effective but safety concerns remain. Nonetheless, for severe refractory IBD cases, stem cell therapy could well become the next-generation treatment option.

RESUMO

BACKGROUND: Although validated patient-reported outcome (PRO) measurements can categorize patients with inflammatory bowel disease (IBD) into clinical remission or active disease, patients may have different definitions of remission. The purpose of this study was to compare patient-defined remission to remission based on PRO measures and physician global assessment (PGA) and to understand the clinical and demographic factors associated with disagreements. METHODS: We retrospectively analyzed 3257 de-identified surveys from 2004 IBD patients who consented to participate in the Crohn's and Colitis Foundation's IBD Qorus Learning Health System between September 2019 and February 2021. We used logistic regression models with generalized estimating equations to analyze the clinical and demographic factors (eg, age, disease duration, health confidence) associated with discordance between patient-defined remission (yes/no) and PRO-defined remission for ulcerative colitis (UC; PRO2: stool frequency, rectal bleeding) and Crohn's disease (CD; PRO-3: average number of liquid stools, abdominal pain, well-being). RESULTS: Among patients with UC, overall concordance was 79% between patient self-report and PRO2-defined remission and 49% between patient self-report and PGA-defined remission. Among patients with CD, overall concordance was 69% between patient self-report and PRO3-defined remission and 54% between patient self-report and PGA-defined remission. Patients in PRO-defined remission were more likely to report active disease if they had IBD <5 years and low health confidence. Patients with PRO-defined active disease were more likely to report remission if they were not using prednisone and had high health confidence. CONCLUSION: Discordance exists between how remission is defined by patients, PRO measures, and PGA.


Discordance between patients' self-reported remission and remission defined based on patient-reported outcomes was observed in 31% of Crohn's disease visits and 21% of ulcerative colitis visits. Disease duration and health confidence were associated with discordance.

RESUMO

Background: Perianal fistulae can undermine physical, emotional, and social well-being in patients with Crohn's disease and are challenging to manage. Social media offers a rich opportunity to gain an in-depth understanding of the impact of perianal fistulae on patients' daily lives outside of controlled environments. In this study, we conducted social media analytics to examine patients' experiences with perianal fistulae and assessed the impact of perianal fistulae on patients' behavior and overall well-being. Methods: We used a mixed-method approach to examine 119 986 publicly available posts collected from 10 Crohn's disease forums in the United States between January 01, 2010 and January 01, 2020. Discussions related to Crohn's perianal fistulae were retrieved. We randomly selected 700 posts and qualitatively analyzed them using an inductive thematic approach. We then applied a latent Dirichlet allocation probabilistic topic model to explore themes in an unsupervised manner on the collection of 119 986 posts. Results: In the qualitative analysis, 5 major themes were identified: (1) burden of perianal fistula; (2) challenges associated with treatment; (3) online information seeking and sharing; (4) patient experiences with treatments; and (5) patients' apprehension about treatments. In the quantitative analysis, the percentages of posts related to the major themes were (1) 20%, (2) 29%, (3) 66%, and (4) 28%, while the topic model did not identify theme 5. Conclusions: Social media reveals a dynamic range of themes governing patients' perspectives and experiences with Crohn's perianal fistulae. In addition to the biopsychosocial burden, patients frequently express dissatisfaction with current treatments and often struggle to navigate among available management options.

RESUMO

OBJECTIVE: We developed five educational videos through a user-centered approach for patients with inflammatory bowel diseases (IBD) and their families and friends. Here, we assessed if IBD patient activation and family and friends' abilities to understand IBD patients' thoughts, feelings, and behaviors (i.e., perspective taking) changed after watching the videos. METHODS: Through a pre-post survey, we assessed patient activation and perspective taking levels in people with a self-reported IBD diagnosis and their family and friends, respectively, before and after watching one of the videos. RESULTS: Among 767 participants with IBD, patient activation scores increased significantly after watching each video. In regression analyses, patient activation levels were less likely to increase in biologic-naïve participants after viewing the coping video. Among 232 people who knew someone with IBD, perspective taking scores increased significantly in 8/9 domains, which was more likely to occur among women. CONCLUSIONS: Educational videos developed through a user-centered approach were associated with higher self-reported IBD patient activation scores and perspective taking levels among family and friends. PRACTICE IMPLICATIONS: These videos, which are now widely disseminated on social media, serve as a model for how to create educational materials for improving patient activation and empathy in the social media era.

RESUMO

BACKGROUND: We aimed to examine the associations between health confidence (one's belief on the degree of control on their health and disease), inflammatory bowel disease (IBD) outcomes, and health care utilization among adults with IBD. METHODS: In total, 17,205 surveys were analyzed from a cross-sectional sample of IBD patients at 23 gastroenterology (GI) practices participating in the Crohn's and Colitis Foundations' IBD Qorus Learning Health System. We used bivariate analyses and multivariable logistic regression to examine associations between health confidence and disease activity, opioid use, glucocorticoid use, well-being, and health care utilization. We used receiver operating curve analysis to determine a clinically relevant cutoff for health confidence (0-10 Likert scale). RESULTS: Health confidence was highly correlated with patients' well-being, symptomatic disease activity, opioid use, and glucocorticoid use (all P < .0001). Health confidence scores <8 had 69% sensitivity for emergency department (ED) visits and 66% for hospitalizations. In patients with inactive disease, patients with low health confidence (<8) were 10 times more likely to call/message the GI office >4 times/month (adjusted odds ratio [aOR], 10.3; 95% CI, 6.1-17.3; P < .0001), 3-4 times more likely to have an IBD-related ED visit (aOR, 4.0; 95% CI, 2.9, 5.4. P < .0001), or hospitalization (aOR, 3.0, 95% CI, 2.1, 4.1, P < .0001) compared with patients with high health confidence (≥8). CONCLUSIONS: In a large, national sample of adults with IBD, there were strong associations between patients' health confidence and multiple disease outcome measures. Health confidence scores <8 on a 0-10 Likert scale may be clinically useful to screen for patients who are at risk for ED visits and hospitalizations.
