A randomised controlled trial of self-help interventions in patients with a primary care diagnosis of irritable bowel syndrome

Is chronic pelvic pain a comfortable diagnosis for primary care practitioners: a qualitative study

Background

Chronic pelvic pain (CPP) has a prevalence similar to asthma and chronic back pain, but little is known about how general practitioners (GPs) and practice nurses manage women with this problem. A clearer understanding of current management is necessary to develop appropriate strategies, in keeping with current health care policy, for the supported self-management of patients with long term conditions. The aim of this study was to explore GPs' and practice nurses' understanding and perspectives on the management of chronic pelvic pain.

Methods

Data were collected using semi-structured interviews with a purposive sample of 21 GPs and 20 practice nurses, in three primary care trusts in the North West of England. Data were analysed using the principles of Framework analysis.

Results

Analysis suggests that women who present with CPP pose a challenge to GPs and practice nurses. CPP is not necessarily recognized as a diagnostic label and making the diagnosis was achieved only by exclusion. This contrasts with the relative acceptability of labels such as irritable bowel syndrome (IBS). GPs expressed elements of therapeutic nihilism about the condition. Despite practice nurses taking on increasing responsibilities for the management of patients with long term conditions, respondents did not feel that CPP was an area that they were comfortable in managing.

Conclusions

The study demonstrates an educational/training need for both GPs and practice nurses. GPs described a number of skills and clinical competencies which could be harnessed to develop a more targeted management strategy. There is potential to develop facilitated self- management for use in this patient group, given that this approach has been successful in patients with similar conditions such as IBS.

A randomized controlled trial of a cognitive behavioural therapy-based self-management intervention for irritable bowel syndrome in primary care

BACKGROUND

Recent guidelines for the treatment of irritable bowel syndrome (IBS) emphasize the need for research to facilitate home-based self-management for these patients in primary care. The aim of the current study was to test the efficacy of a manualized cognitive behavioural therapy (CBT)-based self-management programme for IBS in a pilot randomized controlled trial (RCT).

METHOD

Sixty-four primary-care patients meeting Rome criteria for IBS were randomized into either self-management plus treatment as usual (TAU) (n=31) or a TAU control condition (n=33). The self-management condition included a structured 7-week manualized programme that was self-administered in conjunction with a 1-hour face-to-face therapy session and two 1-hour telephone sessions. The primary outcome measures were the Subject's Global Assessment (SGA) of Relief and the Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) assessed at baseline, end of treatment (2 months), and 3 and 6 months post-treatment.

RESULTS

Analysis was by intention-to-treat. Twenty-three (76.7%) of the self-management group rated themselves as experiencing symptom relief across all three time periods compared to seven (21.2%) of the TAU controls [odds ratio (OR) 12.2, 95% confidence interval (CI) 3.72-40.1]. At 8 months, 25 (83%) of the self-management group showed a clinically significant change on the IBS-SSS compared to 16 (49%) of the control group (OR 5.3, 95% CI 1.64-17.26).

CONCLUSIONS

This study provides preliminary evidence that CBT-based self-management in the form of a structured manual and minimal therapist contact is an effective and acceptable form of treatment for primary-care IBS patients.

Patients with physiological acid exposure and positive symptom association scores: a distinct group within the GORD spectrum

Studies comparing pH-metrically well-characterized gastro-oesophageal reflux disease (GORD) patients with physiological reflux to GORD patients with pathological reflux, with regard to clinical and epidemiological data, are lacking. We included 273 GORD patients with pathological 24-h pH-monitoring (pH+), defined as pH<4 > or = 6% of time. A symptom index (SI) > or = 50% was considered positive, as well as a symptom association probability (SAP) > or = 95%. We included 84 GORD patients with physiological acid exposure (pH-) and a positive SI and/or SAP. Manometry and endoscopy reports were reviewed. Subjects completed questionnaires about demographics and medical history, functional dyspepsia and irritable bowel syndrome, the Nepean Dyspepsia Index symptom score and the RAND-36 quality of life scale. pH- patients were younger (45 vs 50 years, P = 0.003), more often female (60%vs 39%, P = 0.001), smoked more (31%vs 19%, P = 0.021) and reported proton pump inhibition failure more often (47%vs 32%, P = 0.027). A hypotensive lower oesophageal sphincter was less common in pH- patients (18%vs 34%, P = 0.008) and distal oesophageal contraction amplitude was higher (11 vs 9.5 kPa, P = 0.045). pH- patients had hiatal hernia and oesophagitis less often (48%vs 73%, P < 0.0005; 36%vs 54%, P = 0.012 respectively). pH- patients less often reported no other symptoms besides GORD (20%vs 34%, P = 0.015). pH- patients scored worse at the Nepean (reflux 19 vs 12 out of 39, P < 0.0005; dyspepsia 54 vs 38 out of 156, P < 0.0005). In the subgroup of patients who have physiological oesophageal acid exposure the enhancement of the perceived symptom burden appears to be the most important mechanism in GORD pathogenesis.

Providing reviews of evidence to COPD patients: controlled prospective 12-month trial

The aim of this study was to evaluate a novel patient-held manual designed to reduce the evidence–practice gap in chronic obstructive pulmonary disease (COPD). The intervention manual contained summaries of research evidence. It was developed using current best practice for patient information materials and designed to cause discussion of evidence between patient and doctor. A controlled before-and-after study was employed in two similar but geographically separate regions of metropolitan Adelaide, South Australia. Participants had moderate to severe COPD, with 249 included at baseline and 201 completing the study. Evidence-based COPD management was measured using an indicator with three components: rates of influenza vaccination, bone density testing, and pulmonary rehabilitation. A survey of behavioral steps leading to practice change was conducted with the trial. Analysis, by median split of socioeconomic disadvantage, showed significant difference between study arms for only one component of the indicator of evidence-based practice, enrolment in pulmonary rehabilitation and only for the most socioeconomically disadvantaged stratum. For both socioeconomic strata, more intervention participants than control participants reported remembering being given the information material, reading part or all, and finding it very or quite helpful. Other significant differences were restricted to the stratum of greatest socioeconomic disadvantage: reading all of the material, learning from it, referring back, and talking to a doctor about a topic from the material. Above 90% of all participants who received the manual reported reading from it, 42% reported discussing topics with a doctor, but only 10% reported treatment change attributable to the manual. We have found that people with COPD will read an evidence manual developed using current best practice. However, the study demonstrated improvement for only one of the three components of an indicator of evidence-based disease management for only the most socioeconomically disadvantaged stratum of participants. Future interventions should be designed to better translate reading uptake into evidence-based disease management.

The centrality of personal relationships in the creation and amelioration of mental health problems: the current interdisciplinary case

An interdisciplinary case is made for the centrality of personal relationships in the creation and amelioration of mental health problems. Taking the work of John Bowlby as a starting point, the article summarizes accumulating evidence from the past 50 years about the link between childhood adversity and adult mental health problems. Evidence is also reviewed about contemporary interpersonal impacts on adult mental health from natural social settings and in professional therapy. These empirical summaries are then discussed in the context of dominant trends in professional knowledge about bio-determinism within psychiatry and the emphasis upon models and techniques in professional and political advocates of the psychological therapies. It is concluded that the latter trends are diverting us from policies, which properly concede the importance of relationships for improving the mental health of the population.

Development of an educational intervention for patients with Irritable Bowel Syndrome (IBS): a pilot study

Background

Many IBS patients experience that they receive limited information and that the health care system does not take their complaints seriously. We aimed to develop a structured patient education, an 'IBS school', and investigate if the efficacy could be evaluated in terms of improved knowledge, symptom severity and health related quality of life (HRQOL).

Methods

The IBS school consisted of six weekly two hour sessions in a group setting. Five different health care professionals were responsible for one session each. Questionnaires covering patients' experience of the education, perceived knowledge about IBS, gastrointestinal symptoms, and HRQOL, were used for evaluation at baseline and at three, six, and twelve months after education.

Results

Twelve IBS patients were included. The patients were overall satisfied with the IBS school. In line with this, the gastrointestinal symptoms, HRQOL, and perceived knowledge about IBS improved significantly after the education.

Conclusion

An IBS school seems to be a proper method to meet the patients' need of information about IBS and also to improve the patients' gastrointestinal symptoms, HRQOL, and knowledge about IBS. Further controlled studies are now needed in larger numbers of patients to confirm these preliminary results in order to implement this intervention in clinical practice.

Self-administered cognitive behavior therapy for moderate to severe irritable bowel syndrome: clinical efficacy, tolerability, feasibility

BACKGROUND & AIMS

Given the limitations of conventional therapies and restrictions imposed on newer pharmacologic agents, there is an urgent need to develop efficacious and efficient treatments that teach patients behavioral self-management skills for relieving irritable bowel syndrome (IBS) symptoms and associated problems.

METHODS

Seventy-five Rome II diagnosed IBS patients (86% female) without comorbid gastrointestinal disease were recruited from local physicians and the community and randomized to either 2 versions of cognitive behavior therapy (CBT) (10-session, therapist-administered CBT vs 4-session, patient-administered CBT) or a wait list control (WLC) that controlled for threats to internal validity. Final assessment occurred 2 weeks after the 10-week treatment phase ended. Outcome measures included adequate relief from pain and bowel symptoms, global improvement of IBS symptoms (CGI-Improvement Scale), IBS symptom severity scale (IBS SSS), quality of life (IBSQOL), psychological distress (Brief Symptom Inventory), and patient satisfaction (Client Satisfaction Scale).

RESULTS

At week 12, both CBT versions were significantly (P < .05) superior to WLC in the percentage of participants reporting adequate relief (eg, minimal contact CBT, 72%; standard CBT, 60.9%; WLC, 7.4%) and improvement of symptoms. CBT-treated patients reported significantly improved quality of life and IBS symptom severity but not psychological distress relative to WLC patients (P < .0001).

CONCLUSIONS

Data from this pilot study lend preliminary empirical support to a brief patient-administered CBT regimen capable of providing short-term relief from IBS symptoms largely unresponsive to conventional therapies.

Self-management for people with inflammatory bowel disease

In North America and the United Kingdom, we are in the age of self-management. Many patients with chronic diseases are ready to participate in the therapeutic decision-making process, and join their physicians in a co-management model. It is particularly useful to consider this concept at a time when physician shortages and waiting times are on the front page every day, with no immediate prospect of relief. Conditions such as diabetes, asthma, chronic obstructive pulmonary disease, recurrent urinary tract infections and others lend themselves to this paradigm of medical care for the informed patient. The present paper reviews some of the literature on self-management for the patient with inflammatory bowel disease (IBD), and provides a framework for the use of self-management in the IBD population, with emphasis on the concept of a patient passport, and the use of e-mail, supported by an e-mail contract, as proposed by the Canadian Medical Protective Association. Examples of specific management strategies are provided for several different IBD scenarios. Eliminating the need for some office visits has clear environmental and economical benefits. Potential negative consequences of this form of patient care are also discussed.

Functional bowel disorders in primary care: factors associated with health-related quality of life and doctor consultation

BACKGROUND

The role of psychological factors in irritable bowel syndrome (IBS) remains unclear, particularly in a primary care setting, where relatively little research on this common and costly condition has been carried out. The aim of this study was to investigate the relative contribution of physical and psychological factors to health-related quality of life and health-care utilization in patients with functional bowel disease (IBS-like symptoms) in primary care. We also wished to establish the relevance of formal diagnostic criteria to IBS in the primary care setting.

METHODS

This study used a cross-sectional design. Four hundred twenty patients with functional bowel disorders in primary care completed a series of measures, including bowel symptom status and severity, severity of psychological distress, personality, and quality of life. The number of visits to a general practitioner (GP) in the previous 12 months was recorded.

RESULTS

The following variables were independently and highly significantly associated with health-related quality of life in patients with functional bowel disorders in primary care: total psychological symptom score, diarrhea severity, abdominal pain for >12 weeks, and abdominal distension. A similar pattern emerged between patients who met meet Rome II criteria for IBS and patients who did not meet Rome II criteria for IBS. Relatively few variables (either physical or psychological) had a major impact on the number of GP consultations, with the exception of frequency of bowel movements.

CONCLUSION

This study confirms that psychological factors are significantly associated with health-related quality of life in patients with IBS in primary care. Physical symptom severity is also important. Relatively few symptom measures, either physical or psychological, have a major impact on doctor consultation rates in primary care.

Patient education in gastro-oesophageal reflux disease: a randomized controlled trial

OBJECTIVES

Gastro-oesophageal reflux disease (GORD) is chronic, affects 8-20% of the population, impairs quality of life (QoL) and generates substantial health-related costs. Patient education is intended to improve patients' disease-related competency, potentially enabling them to deal more efficiently with their disease, eventually improving QoL and reducing healthcare cost. This study aimed to investigate the effects of a group-based education programme for patients with mild GORD.

METHODS

Patients with GORD were randomly allocated to education (n=102) or control (n=109). The education programme was designed as a structured dialogue conveying medical information about the pathophysiology and prognosis, pharmacological and nonpharmacological treatment of GORD, patients' rights and use of healthcare. Outcomes were measured using general QoL [General Health Questionnaire-30 (GHQ-30)], disease-specific QoL [Digestive Symptoms and Impact Questionnaire (DSIQ)], global QoL and healthcare use at 2 and 12 months after the educational programme.

RESULTS

No statistically significant differences were found in GHQ-30, DSIQ or global QoL at 2 or 12 months' follow-up between the GORD-education group and controls. In the GORD-education group, patients who had completed primary school education only showed improved QoL at 12 months on both GHQ and DSIQ, whereas patients who had completed advanced schooling showed no change. No difference was found between the groups in their use of healthcare.

CONCLUSION

A group-based education programme for patients with mild GORD showed no effect on QoL or use of healthcare. Subgroup analyses showed improved QoL only in patients with primary school education, who had been allocated to GORD education.

Support for self care for patients with chronic disease

Anne Kennedy, Anne Rogers, and Peter Bower argue that effective self care requires fundamental changes in professional attitudes and the way health care is delivered

Self-management education programmes by lay leaders for people with chronic conditions

BACKGROUND

Lay-led self-management programmes are becoming widespread in the attempt to promote self-care for people with chronic conditions.

OBJECTIVES

To assess systematically the effectiveness of lay-led self-management programmes for people with chronic conditions.

SEARCH STRATEGY

We searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2005, Issue 1), MEDLINE (January 1986 to May 2006), EMBASE (January 1986 to June 2006), AMED (January 1986 to June 2006), CINAHL (January 1986 to June 2006), DARE (1994 to July 2006, National Research Register (2000 to July 2006), NHS Economic Evaluations Database (1994 to July 2006), PsycINFO (January 1986 to June 2006), Science Citation Index (January 1986 to July 2006), reference lists and forward citation tracking of included studies. We contacted principal investigators and experts in the field. There were no language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing structured lay-led self-management education programmes for chronic conditions against no intervention or clinician-led programmes.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information. Results of RCTs were pooled using a random-effects model with standardised mean differences (SMDs) or weighted mean differences (WMDs) for continuous outcomes.

MAIN RESULTS

We included seventeen trials involving 7442 participants. The interventions shared similar structures and components but studies showed heterogeneity in conditions studied, outcomes collected and effects. There were no studies of children and adolescents, only one study provided data on outcomes beyond six months, and only two studies reported clinical outcomes.

PRIMARY OUTCOMES

Health status: There was a small, statistically-significant reduction in: pain (11 studies, SMD -0.10 (95% confidence interval (CI) -0.17 to -0.04)); disability (8 studies, SMD -0.15 (95% CI -0.25 to -0.05); and fatigue (7 studies, SMD -0.16 (95% CI -0.23 to -0.09); and small, statistically-significant improvement in depression (6 studies, SMD -0.16 95% CI -0.24 to -0.07). There was a small (but not statistically- or clinically-significant) improvement in psychological well-being (5 studies; SMD -0.12 (95% CI -0.33 to 0.09)); but no difference between groups for health-related quality of life (3 studies; WMD -0.03 (95% CI -0.09 to 0.02). Six studies showed a statistically-significant improvement in self-rated general health (WMD -0.20 (95% CI -0.31 to -0.10). Health behaviours: 7 studies showed a small, statistically-significant increase in self-reported aerobic exercise (SMD -0.20 (95% CI -0.27 to -0.12)) and a moderate increase in cognitive symptom management (4 studies, WMD -0.55 ( 95% CI -0.85 to -0.26)). Healthcare use: There were no statistically-significant differences between groups in physician or general practitioner attendance (9 studies; SMD -0.03 (95% CI -0.09 to 0.04)). There were also no statistically-significant differences between groups for days/nights spent in hospital (6 studies; WMD -0.32 (95% CI -0.71 to 0.07)). Self-efficacy: (confidence to manage condition) showed a small statistically-significant improvement (10 studies): SMD -0.30, 95% CI -0.41 to -0.19. No adverse events were reported in any of the studies.

AUTHORS' CONCLUSIONS

Lay-led self-management education programmes may lead to small, short-term improvements in participants' self-efficacy, self-rated health, cognitive symptom management, and frequency of aerobic exercise. There is currently no evidence to suggest that such programmes improve psychological health, symptoms or health-related quality of life, or that they significantly alter healthcare use. Future research on such interventions should explore longer term outcomes, their effect on clinical measures of disease and their potential role in children and adolescents.

Irritable bowel syndrome: patients' attitudes, concerns and level of knowledge

BACKGROUND

Irritable bowel syndrome (IBS) is a common, chronic disorder that reduces patients' quality-of-life. Although highly prevalent, little is known about patients' understanding of this disorder.

AIM

To evaluate the knowledge, fears and concerns of IBS patients.

METHODS

Seven hundred thirty-six IBS patients (Rome II criteria) were eligible for inclusion in this prospective study. Each patient received a validated questionnaire to evaluate knowledge, attitudes and fears regarding IBS.

RESULTS

A total of 261 of 664 potential respondents completed the questionnaire (39.3%). 83% of respondents were women, with a mean age of 53.7 years, and mean duration of symptoms of 14.2 years. Patients frequently believed that IBS develops because of anxiety (80.5%), dietary factors (75.1%) and depression (63.2%). Few respondents (28.7%) recognized that abdominal pain is the cardinal symptom of IBS, and 40.6% stated that colonoscopy can diagnose IBS. One in seven patients stated that IBS turns into cancer, and 29.9% noted that IBS increases the risk of inflammatory bowel disease.

CONCLUSIONS

Many IBS patients have significant misconceptions regarding the nature of their disease and its prognosis. An overwhelming majority of IBS patients believe that anxiety, dietary factors and depression cause IBS. These findings are discordant with physicians' views and practices and highlight the need for patient-oriented educational programs.

Re-thinking the relationship between long-term condition self-management education and the utilisation of health services

Encouraging self-management has been viewed as one means of reducing health service utilisation and contributing to improved demand management. However, the processes and imputed relationship between self-management education skills and health service contact are poorly understood. This paper reports on data from an embedded qualitative study which ran alongside a randomised controlled trial in England designed to test the clinical and cost effectiveness of a self-care support policy which found no statistically significant reductions in health service utilisation. Drawing on concepts from the sociology of chronic illness, analyses suggest that the biographical and social context relevant to individuals' experience of living with a long-term condition, history of health service utilisation, and relationships with health professionals are relevant to understanding the impact of self-management education and related policies aimed at bringing about changes in service use. Our study suggests that future health policy assumptions about utilisation in the context of chronic disease management and self-care support polices may benefit by acknowledging the complex, contextual and recursive nature of health service utilisation operating in the life worlds of patients' experience of living with a long-term condition.

Continuity and change? Exploring reactions to a guided self-management intervention in a randomised controlled trial for IBS with reference to prior experience of managing a long term condition

Self-care interventions are promoted as effective strategies for improving the quality of life and health outcomes for individuals with long-term health conditions. Outcome measures used in evaluations using Randomised Controlled Trials (RCTs) are not designed to consider patients' prior management strategies and experience of illness. Yet the experience of illness literature suggests that adjusting to living with chronic illness, together with broader contextual influences, are likely to be relevant to understanding responses to self-management initiatives. Using group and individual interview data we attempt to illuminate the transposition of IBS from a condition unsatisfactorily managed by medicine to one successfully managed within the life worlds of individuals. If routine embedding of complex interventions depends on the accomplishment of integration and workability in patients' everyday lives then the design and evaluation of such interventions should view participation as part of a process of continuity as well as change. Responses to formal self-management can be extended beyond psychological and other quantitatively measured outcomes. A useful addendum to trial outcomes for self-management education is an understanding of change as being inextricably linked to people's previous attempts to, and experience of, managing long-term conditions. We suggest that the benefits of understanding the prior experience of managing illness and contact with health services include the acceptability and workability of complex interventions in patients' everyday lives.

All Roads Lead to Rome: Update on Rome III Criteria and New Treatment Options

The recently published Rome III criteria reflect current understanding of functional gastrointestinal disorders. These criteria include definitions of these conditions and their pathophysiologic subtypes and offer guidelines for their management. At the 2006 Annual Scientific Meeting of the American College of Gastroenterology, a panel of experts discussed these criteria as they pertain to irritable bowel syndrome, functional dyspepsia, and chronic constipation. This article reviews the panel's findings, highlights the differences between the Rome II and III criteria, and summarizes best treatment options currently available to practitioners and their patients.

Irritable bowel syndrome

Conceptually, the irritable bowel syndrome (IBS) has been considered a brain-gut functional disorder, but this paradigm is under serious challenge. There is increasing evidence that organic disease of the gastrointestinal tract can be identified in subsets of patients who fulfil the Rome criteria for IBS. Evidence for subtle inflammatory bowel disease, serotonin dysregulation, bacterial overgrowth and central dysregulation continue to accumulate. The underlying causes of IBS remain to be adequately identified, but postinfectious IBS is a clear-cut entity. Furthermore, a genetic contribution to IBS also seems likely. Diagnosis continues to be based on the symptom profile and the absence of alarm features. A heightened awareness of coeliac disease masquerading as IBS is becoming accepted. Management remains largely based on symptomatic rather than on disease-modifying therapy, but this is likely to change in the near future. Here, recent advances in the pathophysiology and management of IBS are considered.

Self-help interventions in irritable bowel syndrome

Self‐management approach in irritable bowel syndrome was effective in reducing primary care consultations and perceived symptom severity
