Structured patient education is superior to written information in the management of patients with irritable bowel syndrome: a randomized controlled study

A comparison of a short nurse-based and a long multidisciplinary version of structured patient education in irritable bowel syndrome

OBJECTIVE

Structured multidisciplinary patient group education has positive effects on symptoms, health-related quality of life, and disease-related knowledge in patients with irritable bowel syndrome (IBS), but few studies comparing different forms of educational interventions are available. Our aim was to compare the effects of long multidisciplinary group education with a short nurse-based group education with regard to symptoms, knowledge, quality of life, and satisfaction with the intervention in IBS patients.

METHODS

Patients with IBS according to the Rome II criteria were randomized to either short nurse-based or a long multidisciplinary-based education. The effects were evaluated by self-administered questionnaires at 3, 6, and 12 months after baseline, and compared between the groups.

RESULTS

No differences in effects were detected in the between-group comparisons at any of the follow-up assessments. However, positive effects on symptoms, knowledge, quality of life, and satisfaction with the intervention were found in both the short and the long version.

CONCLUSION

A short, nurse-based educational intervention seems to be as efficacious as a longer multidisciplinary version. In both groups, positive effects on patients' well-being were found to a similar extent. This is an important finding that, from a cost-effective perspective, could contribute toward an optimized management of patients with IBS.

Learning about oneself through others: experiences of a group-based patient education programme about irritable bowel syndrome

BACKGROUND

People with irritable bowel syndrome (IBS) often experience severe illness-related troubles in their everyday lives. Many persons also perceive their disease-related knowledge to be insufficient, and they feel dissatisfied with their inability to improve well-being. Previous research about patient education and IBS has emphasized biomedical outcomes of symptoms, health-promoting behaviours, coping and health-related quality of life, rather than people's experiences.

AIM

To explore people's experiences of participating in a multidisciplinary group-based patient education programme about IBS and of the influence of this programme on everyday life with illness.

METHODS

Focus group interviews were performed with 31 persons after their participation in the patient education programme. Interpretive description guided the inductive analysis of data. The study was approved by the local research ethics committee.

FINDINGS

The analysis revealed four patterns; being part of a safe community, learning about oneself through others, understanding and controlling the body and illness as a whole, and being outside of the community. The pattern of learning about oneself through others can be described as a reciprocal activity of learning by listening to, telling and observing others. Being among similar others had created feelings among most of the focus group participants of being part of a safe community where taboo subjects related to IBS-symptoms could be outspoken. Understanding the body and illness as a whole had enhanced their ability to interpret bodily signals and to handle trouble some situations with greater self-confidence, and this regained their access to the social everyday world.

CONCLUSION

The combination of reciprocal sharing of experiences and the provision of professional scientific knowledge during the patient education programme together contributed to a growing readiness to improve well-being in everyday life, for most of the participating individuals. This was based on new understandings of the body and illness as a whole and of new abilities to make knowledge-based decisions about what strategies to use in overcoming illness-related troubles.

Questioning the bacterial overgrowth hypothesis of irritable bowel syndrome: an epidemiologic and evolutionary perspective

Although studies indicate that small intestinal bacterial overgrowth (SIBO) is prevalent in irritable bowel syndrome (IBS), it remains unclear whether SIBO causes IBS. This review presents an epidemiologic and evolutionary inquiry that questions the bacterial overgrowth hypothesis of IBS, as follows. (1) Although the hypothesis may be biologically plausible, there is also a strong rationale for competing hypotheses; it is unlikely that SIBO is the predominant cause of IBS in all comers, because competing explanations are sensible and defensible. Moreover, data indicate that the test used to promulgate the SIBO hypothesis - the lactulose hydrogen breath test - may not have measured SIBO in the first place. (2) We do not have evidence of SIBO being absent before IBS symptoms, and present after IBS emerges. (3) There is not a dose-response relationship between small intestinal microbiota and IBS symptoms. (4) The relationship between SIBO and IBS is highly inconsistent among studies. (5) Many effective IBS therapies do not address SIBO at all, yet have a more favorable "number needed to treat" than antibiotics. (6) IBS does not behave like a traditional infectious disease, suggesting that microbes may not principally cause the syndrome. (7) Other factors may confound the relationship between SIBO and IBS, including proton pump inhibitors. (8) Whereas the brain-gut hypothesis is evolutionary sensible, the bacterial hypothesis is harder to defend from an evolutionary perspective. The article concludes that bacteria may contribute to some IBS symptoms, but that bacteria cannot be the only explanation, and a causal link between SIBO and IBS is not secure.

A cognitive-behavioral treatment for irritable bowel syndrome using interoceptive exposure to visceral sensations

BACKGROUND

Irritable bowel syndrome (IBS) is a chronic and debilitating medical condition with few efficacious pharmacological or psychosocial treatment options available. Evidence suggests that visceral anxiety may be implicated in IBS onset and severity. Thus, cognitive-behavioral treatment (CBT) that targets visceral anxiety may alleviate IBS symptoms.

METHODS

The current study examined the efficacy of a CBT protocol for the treatment of IBS which directly targeted visceral sensations. Participants (N = 110) were randomized to receive 10 sessions of either: (a) CBT with interoceptive exposure (IE) to visceral sensations; (b) stress management (SM); or (c) an attention control (AC), and were assessed at baseline, mid-treatment, post-treatment, and follow-up sessions.

RESULTS

Consistent with hypotheses, the IE group outperformed AC on several indices of outcome, and outperformed SM in some domains. No differences were observed between SM and AC. The results suggest that IE may be a particularly efficacious treatment for IBS.

CONCLUSIONS

Implications for research and clinical practice are discussed.

Systematic review: self-management support interventions for irritable bowel syndrome

BACKGROUND

Irritable bowel syndrome is an extremely common and costly condition. Because there is no cure, patients must be supported to manage their own condition.

AIM

To assess systematically the interventions used to support irritable bowel syndrome patient self-management.

METHODS

A search of PubMed, EMBASE, CINAHL and PsycINFO was performed to identify all studies that involved self-management support interventions for irritable bowel syndrome. Studies that compared the self-management-related intervention to a control group were included.

RESULTS

Eleven studies that involved a total of 1657 patients were included. For nearly all studies, the intervention was associated with statistically significant benefits. However, across studies there was significant heterogeneity in terms of sample size, diagnostic criteria, study setting, study design, primary outcome, statistical analyses and study quality. Therefore, individual study results could not be statistically combined.

CONCLUSIONS

Many self-management support interventions appear benefit patients with irritable bowel syndrome. However, studies were limited by methodological flaws. Furthermore, feasibility in 'real world' clinical practice is uncertain. Thus, practical self-management interventions that can be applied across various clinical settings should be developed, and then tested in well-designed clinical trials.
