Introduction

Bowel urgency is increasingly recognized as a common and impactful symptom in patients with Ulcerative Colitis (UC)¹. However, there are limited data exploring the relationship of bowel urgency with work productivity. We examined the relative association of bowel urgency clinically meaningful improvement (CMI) and bowel urgency remission with Work Productivity and Activity Impairment (WPAI) scores in the presence of rectal bleeding (RB) remission and stool frequency (SF) remission as potential confounding variables using data from LUCENT-1 (NCT03518086) and LUCENT-2 (NCT03524092) phase 3 trials.

Aims & Methods

Bowel urgency severity was assessed using the Urgency Numeric Rating Scale (UNRS; 0=no urgency to 10=worst possible urgency). Bowel urgency CMI is a ≥3-point decrease and bowel urgency remission is a UNRS score of 0 or 1². WPAI scores (absenteeism, presenteeism, and work productivity loss in employed patients, and activity impairment in all patients) were measured using a 6-item questionnaire; higher scores indicate greater impairment and less productivity. Mediation analyses were performed to separately examine the relative association between the direct effect of bowel urgency CMI and bowel urgency remission (predictor) and WPAI scores while adjusting for the potential confounding effects of RB remission and SF remission (mediator). Analyses were treatment agnostic and combined patients from mirikizumab and placebo groups from LUCENT-1 (N=1162) and LUCENT-2 (N=544) trials.

Results

At week (W)12 and W52, the direct effect of bowel urgency remission accounted for 43%–49% and 27%–57% of the improvement in all WPAI domain scores except absenteeism, respectively. The association values greater than 100% at W12 and W52 (153% and 148%, respectively) reflect the critical importance of SF remission in the improvement of absenteeism score. Bowel urgency CMI resulted in the largest proportion of improvement in WPAI domain scores (except absenteeism) at W12 (71%–74%) and W52 (66%–78%). Bowel urgency CMI accounted for 68% and 239% of the improvement in absenteeism scores at W12 and W52, respectively. At W52, 750% of the effect was mediated by RB remission.

Conclusion

Improvement in work productivity and regular activities were primarily ascribed to bowel urgency remission or bowel urgency CMI relative to RB remission and SF remission in patients with moderately-to-severely active UC. These findings suggest that bowel urgency is a critical and independent symptom that considerably impacts patients’ productivity.

Introduction

Bowel urgency is increasingly being recognized as an impactful symptom in patients with ulcerative colitis (UC)¹. However, limited information is available regarding its potential association with other patient reported outcomes. We assessed the association of bowel urgency clinically meaningful improvement (CMI) or bowel urgency remission with Inflammatory Bowel Disease Questionnaire (IBDQ) scores whilst adjusting for the potential confounding effects of stool frequency (SF) and rectal bleeding (RB) remission using data from LUCENT-1 (NCT03518086) and LUCENT-2 (NCT03524092) phase 3 trials.

Aims & Methods

Bowel urgency severity was assessed by the Urgency Numeric Rating Scale (UNRS) (0=no urgency to 10=worst possible urgency). Bowel urgency CMI was defined as ≥3-point decrease in UNRS compared to baseline and bowel urgency remission was defined as UNRS of 0 or 1.² IBDQ scores (range: 32–224) were calculated; higher scores indicate better quality of life. Mediation analyses were performed to examine the relative association between direct effects of bowel urgency CMI and bowel urgency remission (separate predictors) and IBDQ scores while adjusting for the potential confounding effects of SF remission and RB remission (mediators). Analyses were treatment agnostic and combined patients from mirikizumab and placebo groups from LUCENT-1 (N=1162) and LUCENT-2 (N=544) trials at Week (W) 12 and 40 (W52 of continuous treatment).

Results

At W12 and W52, bowel urgency remission directly accounted for 44.8% and 32.5% improvement in IBDQ total score, respectively; 22.7% and 39.1% of improvement was mediated by RB remission and 32.5% and 28.4% by SF remission, respectively. At W12, bowel urgency remission resulted in the largest proportion of improvement in each of the IBDQ domain subscores, whereas at W52, RB remission had a greater confounding effect. At W12 and W52, bowel urgency CMI accounted for 70% and 57.3% improvement in IBDQ total score, respectively; 12.8% and 25.6% of effects were mediated by RB remission and 17.2% and 17.1% by SF remission, respectively. Bowel urgency CMI accounted for the largest proportion of association with improvement in each of the IBDQ domain subscores at both W12 and W52.

Conclusion

​Improvements in IBDQ scores were primarily ascribed to bowel urgency remission and bowel urgency CMI relative to RB remission and SF remission, particularly at W12, in patients with moderately-to-severely active UC. These findings suggest that bowel urgency is a critical and independent symptom that considerably impacts patients’ quality of life.

Introduction

The best risk-stratification strategy to predict liver-related outcomes (LROs) in the population remains unclear. The Chronic Liver Disease (CLivD) risk score was recently developed and validated to predict LROs in the population. It could thus identify the at-risk population that warrants liver fibrosis screening with non-invasive tests such as FIB-4. The ClivD score is based on age, sex, waist-hip ratio, alcohol use, smoking, diabetes, and gamma-glutamyltransferase measurement.

Aims & Methods

We investigated the combined/sequential use of the ClivD score and FIB-4 for stratifying the risk for LROs in the UK Biobank population.
From the UK Biobank data, we identified 362,330 individuals with no baseline liver disease and data available to calculate the CLivD score and FIB-4. LROs were ascertained through linkage with electronic healthcare registries for hospitalizations, cancers, and deaths related to compensated or decompensated liver cirrhosis or hepatocellular carcinoma. Discrimination performance was assessed by 10-year competing-risk area-under-the-curve (AUC) values and absolute cumulative risks by the cumulative incidence functions considering death without liver disease as a competing-risk event.

Results

Mean age was 56.6 years (SD 8.1), 48% were men, mean BMI 27.2 kg/m2 (SD 4.6), 5% had diabetes, mean alcohol intake was 16.7 g/week (SD 16.6), and 10% were current smokers.
During a median follow-up of 12.6 years (IQR 12.0-13.4), there were 1285 incident LROs. Both the CLivD score and FIB-4 were significantly associated with LROs (P<0.001). The 10-year AUC-value of the CLivD score was 0.80 (95% CI 0.80-0.80) and of FIB-4, 0.75 (95% CI 0.75-0.75) for the prediction of LROs. The predictive performance of FIB-4 improved as a function of increasing CLivD scores: 10-year AUC values of FIB-4 were 0.61 in the minimal-risk CLivD subgroup as compared to 0.81 in the high-risk CLivD subgroup (Table). This effect modification of CLivD for FIB-4’s discrimination performance was also evident for absolute risks. Namely, within the minimal-risk CLivD subgroup, 10-year cumulative incidences of LROs ranged from 0.05% to 0.3% between low and high FIB-4 strata (Table). In contrast, within the high-risk CLivD subgroup, 10-year cumulative incidences of LROs ranged from 1.7% to 21.6% between low and high FIB-4 strata.

Conclusion

Defining the at-risk population by the CLivD score markedly improves the predictive performance of FIB-4. Thus, sequential use of the CLivD score and FIB-4 emerges as a simple way to stratify the population regarding the risk for LRO.

Introduction

A successful colonoscopy requires ideal stool preparation, yet the percentage of insufficient bowel preparation is still very high. Frequently, the patients use website information on colonoscopy preparation. Conversely, the daily activity of the hospital staff consists of spending time with patients, communicating with them and giving answers to a high number of questions coming from patients regarding the preparation for the procedure or the exam itself. Hence, the idea to adopt a rapid and intuitive patient-oriented digital service to respond to their needs, the virtual assistant Eric.

Aims & Methods

Endo-Chat is an automated online communication platform, powered by AI (Artificial Intelligence) with the use of the Natural Language Processing and Deep Learning technologies, that answers procedure-related questions in real-time. The engine is named ERIC, stands for "Endoscopy Robot for Intelligent Chat" and is an intelligent chatbot, capable of answering autonomously to most of the doubts of a patient who is supposed to undergo an endoscopic examination.

Results

Since the introduction of the conversational artificial intelligence system at the Policlinico Gemelli starting from 24^th of January 2022 to the 16^th of March 2023, Eric has been able to autonomously manage 94% of the questions sent by patients, thus forwarding only the remaining 6% (of the requests) to specialized human operators.
We calculated that in the pre-pilot phase, a large part of the daily activity of nurses was dedicated to communicating with patients, around 40 hours per week, while in the post-pilot phase, the time spent for communication was significantly reduced to 15 hours per week. According to OECD Health Statistics 2022, the average annual salary of a European nurse is 35,300 euros, with an annual hypothetical saving of 22,062 euros, comparable to a part-time contract.
Also, the number of cancelled procedures for poor patient preparation has fallen from 22 to 7 per week, considering a volume of 200 procedures per week.
Regarding patient's experience, users can leave voluntary feedback on their virtual assistant experience directly on the ERIC website, evaluating the quality of the service. Patient service evaluations were enthusiastic till now, as 63% rated the service as excellent.

Conclusion

In our observational pilot study, the first in Europe to our knowledge, we assessed the benefits measurement for patients and Hospital staff. Starting from these preliminary interesting results, we can speculate that the introduction of Endo-Chat in high-volume endoscopy service is feasible and useful not only for patients but also for hospital staff.
