Irritable bowel syndrome: what do patients really want?

Do Patients' and Physicians' Perspectives Differ on Preferences for Irritable Bowel Syndrome Treatment?

Irritable bowel syndrome (IBS) is a highly prevalent disorder of gut-brain interaction and poses a significant burden to patients. Pharmacotherapy, diet, and psychotherapy all have largely comparable clinical efficacy. Therefore, factors outside efficacy can have an important impact in determining preferences for a specific therapeutic entity. The aim of this study was to compare the patient and physician perspectives and identify important treatment characteristics regarding the management of IBS. Semistructured interviews were performed among IBS patients (n = 8), fulfilling the Rome IV criteria, and surveys were sent to physicians involved in IBS care (n = 15). Nine important treatment characteristics were revealed: effectiveness, time until response, cessation of response, side effects, location, waiting period, treatment burden, frequency of healthcare appointments, and willingness to pay. Time to response, location, and waiting time were less important for patients compared to physicians. This study assessed important IBS treatment characteristics and provided context to preferences from a patient and physician perspective. These data could be relevant during shared decision-making in clinical practice.

Discrete Choice Experiment Reveals Strong Preference for Dietary Treatment Among Patients With Irritable Bowel Syndrome

BACKGROUND & AIMS

Irritable bowel syndrome (IBS) is a highly prevalent, chronic disorder of the gut-brain interaction that significantly affects quality of life. Several treatments, with comparable clinical efficacy, are available. Patient preferences can therefore be an important determinant of an effective management strategy. Treatment preferences of patients regarding decision making remain unclear. We aimed to examine these preferences and estimate trade-offs between different attributes.

METHODS

A total of 427 patients from the Maastricht IBS cohort were invited to participate. A labeled discrete choice experiment survey, containing 9 scenarios with each 3 alternatives (medication, diet, psychotherapy), was developed in order to estimate preferences. The treatment scenarios were based on 6 attributes: effectiveness, time to response, time until recurrence, side effects, time required, and frequency of appointments. The preference weights and relative importance were analyzed using a mixed logit model.

RESULTS

A total of 185 (43.3%) of 427 potential respondents completed the questionnaire (mean age 49.51 years, 69.2% female). The most preferred treatment was dietary intervention (48.1%), followed by pharmacotherapy (29.2%) and psychotherapy (22.7%). IBS patients preferred a higher effectiveness, shorter time interval to response, longer time interval until recurrence, no severe side effects, and frequent appointments when attending psychotherapy. Younger patients (≤50 years of age) preferred dietary interventions and a long period until recurrence, whereas older patients (>50 years of age) were more inclined to choose pharmacotherapy and the period until recurrence was not important.

CONCLUSIONS

Dietary interventions were the most preferred IBS therapy. Identifying patients' treatment preferences during shared decision making will provide more optimal management strategies and could be the best approach to diminish disease burden.

[Psychosocial Support for People with Ulcerative Colitis and Irritable Bowel Syndrome: A Feasibility Study on Need, Focus and Viability]

OBJECTIVES

Ulcerative colitis (UC) and irritable bowel syndrome (IBS) are associated with high somatic symptom burden, reduced quality of life, and increased psychological distress. The subjective burden, the wish of many patients, and the involvement of psychological processes in symptom perception justify the development of psychosocial support services. We aimed to evaluate need, content and feasibility of such an offer. We included patients with both UC and RDS in order to identify disease-specific and trans-diagnostic aspects for psychosocial interventions.

METHODS

We conducted telephone interviews with adult patients with UC or IBS using a standardized interview guide. We used numerical rating scales and open-ended questions to assess burden of and coping with the disease, disease-related expectations and anxiety, satisfaction with care, support and information needs, and preferences regarding support programs. We calculated descriptive metrics for quantitative variables as well as diagnosis-specific group comparisons. The answers to the open questions were summarised and counted in close accordance with the participants' statements.

RESULTS

N=35 patients (UC: n = 15; IBS: n=20) participated (age: M=40.80, SD=14.56; 71% female). In both groups, patients showed a medium level of disease burden, with higher rates for IBS. Both groups reported disease-related anxiety, with higher levels in patients with IBS. Disease-related expectations did not differ between groups. Patients with IBS showed low satisfaction with care and felt less informed about their disease than patients with UC. Both groups indicated a high motivation of participating in a psychological support program and named illness-related expectations and illness anxiety as important components of such.

DISCUSSION

The results confirm an increased need for psychosocial support and the relevance of disease-related expectations and anxiety for both diseases. Differences in symptom perception and care satisfaction indicate the importance of disease-specific elements in psychosocial therapy programs.

CONCLUSION

The results demonstrate the high need for psychosocial support of patients with UC and IBS and indicate the feasibility of a psychosocial therapy program.

Referrals to a tertiary hospital: A window into clinical management issues in functional gastrointestinal disorders

BACKGROUND AND AIM

To investigate the quality of and reasons for referrals of patients with likely functional gastrointestinal disorders (FGID) and explore patients' experience of clinical management.

METHODS

A cross sectional, mixed-methods study was undertaken. Referrals (July 2013-2015) to one gastroenterology outpatient department triaged as "likely FGID", the referred patients and their referring primary healthcare providers were examined.

RESULTS

A total of 69% of patients reported not yet receiving an initial diagnosis, 52% reported persistent/distressing symptoms or reduced quality of life, 24% feared missed or worsening pathology, and 35% were seeking repeat specialist consultation. Most patients were dissatisfied (40%) or only partially satisfied (36%) with current management. Dissatisfaction was significantly related to the lack of provision of a diagnosis and effective treatment options (P < 0.001). Referral quality was poor and with the reason for referral clearly communicated in only 25%. Common referral reasons included repeat presentations (n = 32), diagnostic uncertainty (n = 19), to ensure nothing is missed (n = 19), patient request (n = 17), no response to treatment (n = 16), and to allay patient fears (n = 14). A total of 28/60 primary healthcare providers were confident that their patient had a FGID, yet sought confirmation (n = 16), second opinion (n = 8), or advice (n = 4).

CONCLUSION

Current management of FGID in usual care is suboptimal, as evidenced by the tertiary referral load, patient dissatisfaction, and the lack of provision of diagnoses and effective treatment options. Some clinicians lack confidence in effectively identifying and managing these conditions. Resources and supports to equip and assist clinicians to identify and manage FGID successfully may enhance patient care.

Development and validation of the Patient-Physician Relationship Scale among patients with irritable bowel syndrome

BACKGROUND

An effective patient-physician relationship (PPR) is essential to the care of patients with irritable bowel syndrome (IBS). We sought to develop and validate an IBS-specific instrument to measure expectations of the PPR.

METHODS

We conducted structured focus groups about PPRs with 12 patients with IBS. Qualitative analysis was used to generate a questionnaire (the Patient-Physician Relationship Scale [PPRS]), which was modified with input from content experts and usability testing. For validation, we administered it online to US adults with IBS. Participants also completed the Functional Bowel Disorder Severity Index, the Rome III Adult Functional gastrointestinal (GI) Disorder Criteria Questionnaire, and modified versions of the Communication Assessment Tool (CAT-15) and Patient-Doctor Relationship Questionnaire (PDRQ-9). We performed principal components factor analysis for the PPRS.

KEY RESULTS

The PPRS contained 32 questions with responses on a 7-item Likert scale. Themes included interpersonal features, clinical care expectations, and aspects of communication. One thousand and fifty-four eligible individuals completed the survey (88% completion rate). Most participants were middle aged (mean 48 years, SD 16.3), white (90%), and female (86%). Factor analysis showed only one relevant factor, relating to quality of PPR. The final scale ranged from possible-96 to +96 (mean 62.0, SD 37.6). It correlated moderately with the CAT-15 (r=.40, P<.001) and PDRQ-9 (r=.30, P<.001), establishing concurrent validity.

CONCLUSIONS & INFERENCES

We describe the development and validation of the first questionnaire for use in measuring patient expectations of the PPR, which can be used for future outcomes studies and training physicians.

Irritable bowel syndrome diagnosis and management: A simplified algorithm for clinical practice

BACKGROUND

Effective management of irritable bowel syndrome (IBS), a common functional gastrointestinal disorder, can be challenging for physicians because of the lack of simple diagnostic tests and the wide variety of treatment approaches available.

OBJECTIVE

The objective of this article is to outline a simple algorithm for day-to-day clinical practice to help physicians navigate key stages to reaching a positive IBS diagnosis and guidance on how to prioritise the use of specific management strategies.

METHODS

This algorithm was based on the opinion of an expert panel evaluating current evidence.

RESULTS

The key principles forming the foundation of this evidence-supported algorithm are: confidently naming and explaining an IBS diagnosis for the patient, followed by assessment of key patient characteristics likely to influence the choice of therapy, such as predominant symptoms, and exploring the patient agenda and preferences. Consultation should always include education and reassurance with an explanatory model of IBS tailored to the patient. Individualised lifestyle changes, dietary modifications, pharmacological therapies, psychological strategies or a combination of interventions may be used to optimise treatment for each patient.

CONCLUSION

The simple visual tools developed here navigate the key stages to reaching a positive diagnosis of IBS, and provide a stepwise approach to patient-centred management targeted towards the most bothersome symptoms. Establishing a strong patient-physician relationship is central to all stages of the patient journey from diagnosis to effective management.
