A qualitative study to explore the symptoms and impacts of Crohn's disease and to develop the Crohn's Disease Diary

The role of mastery in Crohn's disease: a cross-sectional study

Background

Crohn's disease (CD) is a chronic autoimmune inflammatory bowel disease. It is estimated that approximately 40% of individuals with CD are non-adherent to medical prescriptions. This lack of adherence to treatment plans has been linked to an increased risk of hospitalisation and surgical procedures, which can have a detrimental impact on the patient's quality of life (QoL). Furthermore, the CD can impose significant stress on individuals, affecting their mental health and sense of mastery. The term 'mastery' is used to describe an individual's awareness of their abilities and capacities that are essential for effectively managing life events and situations.

Objectives

This study aimed to investigate the role of mastery in relation to medical adherence, distress, perceived social support, QoL, depressive and anxious symptoms and interoception in persons with a diagnosis of CD.

Design

This is a cross-sectional study, involving 261 adults diagnosed with CD.

Methods

Participants completed an online questionnaire comprising validated clinical and psychological scales, which lasted approximately 20 min. Participants were permitted to provide their most recently available medical report.

Results

Patients with CD reported discrete levels of mastery. Two factorial ANOVA highlighted statistically significative differences in mastery in relation to clinical conditions (F(2, 253) = 11.22, p < 0.001) and a significative interaction effect between gender and symptomatology (F(2, 253) = 7.22, p < 0.001). Multiple linear regression illustrated a statistically significant association between mastery, clinical conditions, QoL, stress and interoception (adjusted R square = 0.558; F(14, 211) = 21.32, p < 0.001). Concerning the possible mediator role of mastery between psychological state and medical adherence, no statistically significant results emerged from the mediation model analysis.

Conclusion

This study highlighted an effective impairment of mastery in CD patients, especially among men experiencing mild disease activity. A positive association between mastery and enteroception was outlined. The higher prevalence of distress, anxiety and depressive symptoms connected to mastery was substantiated. Future research should deepen the relationship between mastery with medical adherence.

A patient-reported outcome measure comprising the stool frequency and abdominal pain items from the Crohn's Disease Activity Index: psychometric evaluation in adults with Crohn's disease

BACKGROUND

The Stool Frequency (SF) and Abdominal Pain (AP) items from the Crohn's Disease Activity Index are together referred to as the "Patient Reported Outcome" (PRO). The SF item measures the number of very soft/liquid stools and the AP item measures abdominal pain severity, which are common Crohn's disease (CD) symptoms that patients consider important to treat. This study evaluated the psychometric properties of both PRO items separately and estimated thresholds for clinical remission in moderately to severely active CD.

METHODS

The measurement properties of the PRO items were analyzed using pooled data from VIVID-1 (NCT03926130), a Phase 3, randomized, placebo- and active-controlled study in adults with moderately to severely active CD. Analyses used weekly average scores of the SF and AP items at Weeks 0 (Baseline), 4, 12, and 52. Remission thresholds were estimated using the Patient Global Rating of Severity (PGRS) and Patient Global Impression of Change (PGIC) as primary anchors as well as qualitative evidence from exit interviews.

RESULTS

Data from 1065 participants (mean age: 36.2 years [standard deviation: 13 years]) were analyzed. During the trial, scores improved for both PRO items. Both items demonstrated moderate-to-good test-retest reliability for participants defined as stable based on PGRS and PGIC. Most correlations of related assessments were moderate (0.30≤|ρ| <0.70) with SF and moderate-to-large (0.30≤|ρ| ≤0.90) with AP. By contrast, as anticipated, both items had weak correlations (|ρ| <0.30) with endoscopic and laboratory assessments. The PRO items could discriminate between groups of participants known to differ based on other assessments. The PRO items were able to detect change, as score changes in both items between Baseline and Weeks 12 and 52 differed significantly between most PGRS and PGIC categories. Anchor-based analyses combined with responses from the exit interviews suggested that an SF score of ≤ 3 and an AP score of ≤ 1 could together represent clinical remission.

CONCLUSION

These results support the reliability, construct-validity, and responsiveness of both PRO items in moderately to severely active CD and confirm previously suggested scores for both items that could represent clinical remission.

Psychometric evaluation of the Functional Assessment of chronic illness therapy-fatigue (FACIT-Fatigue) in adults with moderately to severely active Crohn's disease

PURPOSE

To provide further evidence on the psychometric properties of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) in moderately to severely active Crohn's disease (CD), and to determine thresholds for meaningful improvement in fatigue.

METHODS

The FACIT-Fatigue is a 13-item patient-reported outcome measure (range, 0-52) assessing fatigue over the previous week. Using pooled data from the Phase 3 VIVID-1 study of moderately to severely active CD, psychometric properties of FACIT-Fatigue were evaluated up to Week 52. The Patient Global Rating of Severity (PGRS) and Patient Global Impression of Change (PGIC) were used as primary anchors to estimate the FACIT-Fatigue score change representing meaningful improvement.

RESULTS

Psychometric analyses included 1065 adults. The FACIT-Fatigue demonstrated good internal consistency, and correlations between individual items and the total score were moderate to strong. The FACIT-Fatigue score showed moderate to strong correlations with other patient-reported assessments and weak correlations with endoscopic/laboratory assessments. The FACIT-Fatigue differentiated between distinct groups of participants varying in disease severity, quality of life, and fatigue based on PGRS and other assessments. FACIT-Fatigue improvements during the study differed significantly between most PGRS change and PGIC categories. Anchor-based estimates suggested a 6-9-point increase in the FACIT-Fatigue total score as meaningful improvement.

CONCLUSIONS

The FACIT-Fatigue demonstrated strong psychometric properties in the VIVID-1 population of adults with moderately to severely active CD and determined a FACIT-Fatigue score change threshold representing meaningful improvement.

Exit Interviews Exploring Patients' Experience of Change in Crohn's Disease Symptoms During the Mirikizumab Phase 3 Clinical Trial In Adult Patients With Moderately-to-Severely Crohn's Disease

Background

Exit interviews with patients who completed the Phase 3 VIVID-1 mirikizumab clinical trial for moderately-to-severely active Crohn's disease explored the content validity of bowel urgency, stool frequency, and abdominal pain patient-reported outcome measures and perceptions of meaningful within-patient change and remission in these key Crohn's disease symptoms.

Methodology

Cognitive debriefing explored patient understanding of the bowel urgency numeric rating scale (Urgency NRS), Crohn's Disease Activity Index: Stool Frequency (CDAI-SF) and Abdominal Pain (CDAI-AP), and patient global rating/impression of severity/change (PGRS/PGIC). Perceptions of meaningful change and remission were explored qualitatively. Transcripts were analyzed using directed content and framework analysis.

Results

Interviewed participants (N = 62; mean age 44.8 years, 55% female, mean 12.0 years since Crohn's disease diagnosis) were from the United States (n = 29), Czech Republic (n = 10), Poland (n = 8), Germany (n = 7), Canada (n = 4), Australia (n = 3), and the United Kingdom (n = 1). Participants understood the Urgency NRS, CDAI-SF, and CDAI-AP and could use them to rate their bowel urgency, stool frequency, and abdominal pain. Participants considered these symptoms when responding to the PGRS/PGIC. Meaningful change was described as symptom relief resulting in the ability to live daily life without pain or fear/need of rushing to the toilet. Most participants agreed with a proposed remission definition of ≤3 type 6/7 bowel movements and None/Mild abdominal pain.

Discussion

The Urgency NRS, CDAI-SF, and CDAI-AP are content-valid patient-reported outcome measures in Crohn's disease. The PGRS/PGIC are conceptually related global assessments of bowel urgency, stool frequency, and abdominal pain. Patients considered reduction in these symptoms as meaningful and remission.

Patient perception of bowel urgency and remission in moderately to severely active Crohn's disease or ulcerative colitis: a qualitative study

BACKGROUND

Bowel urgency, the sudden and immediate need to have a bowel movement, is common in patients with ulcerative colitis (UC) and Crohn's disease (CD). While its impact in UC is well established, less is known about its importance in CD. Further, what level of bowel urgency control patients with UC or CD would consider to be acceptable or in remission has not been established. This qualitative study aimed to understand perceptions of bowel urgency and remission in these patients.

METHODS

Semi-structured combined concept elicitation and cognitive interviews were conducted to explore how adults with moderate-to-severe UC or CD and current or recent bowel urgency think about the concept of bowel urgency and its remission. The Urgency Numeric Rating Scale (UNRS) was used to examine different levels of bowel urgency severity and to investigate what level of bowel urgency patients would consider as representing remission.

RESULTS

Forty adults (n = 19 UC, n = 21 CD) recruited from six US sites completed the study. Sociodemographic and clinical characteristics were similar in both groups. Both groups reported impacts of bowel urgency on physical, social, professional, and emotional aspects of their lives. Most participants (n = 15 UC, n = 18 CD) reported having experienced one or more incidents of urgency-related fecal incontinence. Most participants considered remission to be a state with a normal or reduced number of bowel movements and no or less frequent bowel urgency, and they noted that remission would increase their ability to engage in daily activities without fear of fecal incontinence. Participants were able to map different levels of severity of bowel urgency to UNRS score ranges (scale: 0-10), and they indicated that a mean UNRS score of 5 (UC) or 4 (CD) would be the highest point on the NRS at which they would still consider their bowel urgency to be in remission.

CONCLUSIONS

Bowel urgency is an important issue for patients with either moderate-to-severe UC or CD, and its remission would improve their lives. Further, these patients may still consider bowel urgency to be in remission even at UNRS scores as high as 4 or 5.

Patient Perspectives of Bowel Urgency and Bowel Urgency-Related Accidents in Ulcerative Colitis and Crohn's Disease

BACKGROUND

Bowel urgency is bothersome in patients with ulcerative colitis (UC) or Crohn's disease (CD) and impacts their well-being but remains underappreciated in clinical trials and during patient-healthcare provider interactions. This study explored the experiences of bowel urgency and bowel urgency-related accidents to identify the concepts most relevant and important to patients.

METHODS

Adults with a diagnosis of moderate-to-severe UC or CD for ≥6 months and experience of bowel urgency in the past 6 months were included. Qualitative, semi-structured interviews were conducted via telephonic/Web-enabled teleconference. Interview transcripts were coded and analyzed in ATLAS.ti 9 using a systematic thematic analysis.

RESULTS

In total, 30 participants with UC or CD (n = 15 each) (mean age 52 and 50 years, respectively) participated in the interviews. The majority of participants were receiving biologic and/or conventional therapy (80% and 87%, respectively). Most participants with UC (87%) and all with CD experienced bowel urgency-related accidents. The most frequently reported symptoms co-occurring with bowel urgency were abdominal pain, fatigue, and abdominal cramping. Abdominal pain and abdominal cramping were the most bothersome co-occurring symptoms of bowel urgency and bowel urgency-related accidents. In both groups, participants reported decreased frequency of bowel urgency and not wanting to experience bowel urgency-related accidents at all as a meaningful improvement.

CONCLUSIONS

Participants with UC or CD expressed bowel urgency and bowel urgency-related accidents to be bothersome and impactful on their daily lives despite use of biologic and/or conventional therapy. These findings underscore the need for development of patient-reported outcome measures to assess bowel urgency in clinical settings.

Patient and Health Care Professional Perceptions of the Experience and Impact of Symptoms of Moderate-to-Severe Crohn's Disease in US and Europe: Results from the Cross-Sectional CONFIDE Study

BACKGROUND

Crohn's disease (CD) significantly affects patients' health-related quality of life and well-being.

AIMS

Communicating Needs and Features of IBD Experiences (CONFIDE) survey explores the experience and impact of moderate-to-severe CD symptoms on patients' lives and identifies communication gaps between patients and health care professionals (HCPs).

METHODS

Online, quantitative, cross-sectional surveys of patients, and HCPs were conducted in the United States (US), Europe (France, Germany, Italy, Spain, United Kingdom), and Japan. Criteria based on previous treatment, steroid use, and/or hospitalization defined moderate-to-severe CD. US and Europe data are presented as descriptive statistics.

RESULTS

Surveys were completed by 215 US and 547 European patients and 200 US and 503 European HCPs. In both patient groups, top three symptoms currently (past month) experienced were diarrhea, bowel urgency, and increased stool frequency, with more than one-third patients wearing diaper/pad/protection at least once a week in past 3 months due to fear of bowel urgency-related accidents. HCPs ranked diarrhea, blood in stool, and increased stool frequency as the most common symptoms. Although 34.0% US and 27.2% European HCPs ranked bowel urgency among the top five symptoms affecting patient lives, only 12.0% US and 10.9% European HCPs ranked it among top three most impactful symptoms on treatment decisions.

CONCLUSION

Bowel urgency is common and impactful among patients with CD in the US and Europe. Differences in patient and HCP perceptions of experiences and impacts of bowel urgency exist, with HCPs underestimating its burden. Proactive communication between HCPs and patients in clinical settings is crucial for improving health outcomes in patients with CD.
