Use of Rome criteria for the diagnosis of irritable bowel syndrome in primary care: a survey among European countries

Level of Knowledge and Attitude Toward Acute Abdomen Among the Public: A Nationwide Study

Introduction Treatment of patients suffering from acute abdominal pain (AAP) is often challenging due to its wide range of associated illnesses, which could delay or prevent the identification of the correct diagnosis. Multiple diagnoses should be considered, particularly those in life-threatening situations needing urgent intervention. Aim This study aimed to assess the level of knowledge among the general population related to acute abdomen and which specialty should be sought for consultation in AAP situations. Subject and methods This cross-sectional study was conducted among the general population living in Saudi Arabia. A self-administered questionnaire was sent to the Saudi population through the Google survey. The questionnaire included basic demographic characteristics (i.e., age, gender, etc.), perceived causes, barriers, the most common symptoms of AAP, and a five-item questionnaire to assess the general population's knowledge about AAP. Results Of the 2,703 respondents, 68.1% were females, and 42.4% were aged between 18 and 25 years old. The digestive system disorders (esophagus, stomach, intestine, and colon) were the most perceived causes that led to AAP (76.6%). The overall mean knowledge score was 1.35 (SD 1.07) out of five points. Accordingly, nearly all (87.2%) were considered to have poor knowledge, 9.5% were considered to have moderate knowledge, and only 3.3% were considered to have good knowledge. Being younger, being a male, and living in the Central Region were the factors associated with increased knowledge. Conclusion There was a lack of knowledge about AAP among the general population in Saudi Arabia. Younger age, gender males, and living in the Central Region were identified as the significant factors of increased knowledge. It is necessary to increase the knowledge of the population regarding acute abdomen. Media awareness campaigns may play a significant role in providing the necessary information to the general public.

A Cross-Sectional Study about Knowledge, Attitude, and Practices among Primary Health Care Physicians in Jazan Province, Saudi Arabia, Regarding Rome IV Criteria for Diagnosis of Irritable Bowel Syndrome

Background and objectives: Most individuals with irritable bowel syndrome (IBS) are diagnosed by primary health care (PHC) physicians. However, a significant percentage of patients remain undiagnosed or misdiagnosed owing to the lack of knowledge or a systematic strategy regarding the use of ROME IV criteria for the diagnosis of IBS. Thus, in this study, we aimed to assess the knowledge, attitude, and practices among primary health care physicians in Jazan Province, Saudi Arabia, regarding ROME IV criteria for the diagnosis of IBS. Methods: A cross-sectional study was conducted using a pretested self-administered questionnaire that determines participants' sociodemographic data and measures knowledge about ROME IV criteria, targeting PHC physicians in Jazan Province, Saudi Arabia. Data were analyzed using the Statistical Package for Social Sciences (SPSS) v.23. Results: We included 200 participants, and the majority of participants in our study (approximately 78%) were aware of the ROME IV diagnostic criteria for IBS; this awareness was associated with age, nationality, specialty, and classification. The participants' mean level of knowledge was 4.30 (out of 6). However, knowledge was higher among Saudi and family medicine doctors in this study, as compared to non-Saudi and doctors of other specialties. More than two-thirds of participants who were aware of ROME IV criteria thought that they are sufficient to diagnose IBS; however, only 47.5% of physicians reported using ROME IV frequently in their daily practice. Conclusions: Most of the participants of this study are aware of ROME IV criteria, and better knowledge was noted among Saudi and family medicine physicians. About 70% thought that ROME IV criteria are effective enough to diagnose IBS, and only about half of the participants use ROME IV criteria in their practice. Therefore, due to its high prevalence in the region, further efforts are required to disseminate basic knowledge and improve attitudes and practices related to ROME IV criteria among PHC physicians of all specialties.

Translational Gap between Guidelines and Clinical Medicine: The Viewpoint of Italian General Practitioners in the Management of IBS

Irritable bowel syndrome (IBS) guidelines are generally developed by experts, with the possibility of a translational gap in clinical medicine. The aim of our study was to assess an Italian group of general practitioners (GPs) for their awareness and use of criteria for the diagnosis and management of IBS. For this purpose, a survey was carried out involving 235 GPs, divided into two groups according to their years of activity: 65 “junior general practitioners” (JGPs) (≤10 years) and 170 “senior general practitioners” (SGPs) (>10 years). JGPs were more familiar with the Rome IV Criteria and Bristol Scale than SGPs. Abdominal pain, bowel movement frequency and bloating were the symptoms most frequently used to make a diagnosis. The most probable causes of IBS were reported to be abnormal gastrointestinal motility and psychological triggers. SGPs reported more frequently than JGPs that challenging management and patient’s request were motivations for a gastroenterological consultation. The practice of clinical medicine is still far from the guidelines provided by the specialists. Abdominal pain related to defecation and changes in bowel frequency are considered to be the more important symptoms for IBS diagnosis, but most GPs, both JGPs and SGPs, like to consider abdominal bloating as another useful symptom. Involving both gastroenterologists and GPs in developing shared guidelines would be highly desirable in order to improve IBS management strategies in everyday clinical practice.

Linaclotide utilization and potential for off-label use and misuse in three European countries

INTRODUCTION

Linaclotide is approved for adults with moderate-to-severe irritable bowel syndrome (IBS) with constipation (IBS-C). Linaclotide is not indicated for weight loss or for patients with inflammatory bowel disease (IBD); it is contraindicated in patients with mechanical bowel obstruction (MBO). Some patients with obesity or eating disorders (ED) may use linaclotide off-label for weight loss or as a laxative.

OBJECTIVES

To describe the use of linaclotide in clinical practice, including patients with potential for off-label use or misuse.

METHODS

Post-authorization safety study conducted in three databases from the linaclotide launch date to 2017: the Clinical Practice Research Datalink in the United Kingdom (UK), the Information System for Research in Primary Care database in Spain and the linked Patient, Prescription and Causes of Death Registries in Sweden. Cohorts of patients were identified as having IBS using diagnostic and treatment codes; IBS subtypes were identified using symptoms and treatment codes; patients with obesity, ED, MBO, and IBD were identified using diagnostic codes or body mass index.

RESULTS

There were 1319, 1981, and 5081 linaclotide users from the United Kingdom, Spain, and Sweden with a median age of 45, 57, and 51 years, respectively; most were females. In the United Kingdom, Spain, and Sweden, respectively: 59.0%, 60.3%, and 31.3% of linaclotide users had an IBS diagnosis recorded, and among those, 68.8%, 61.3%, and 92.7% were classified as IBS-C. The proportions of linaclotide users considered at risk for potential off-label use for weight loss or as a laxative were 17.1%, 29.7%, and 1.7%, and the proportions of users considered at risk of misuse due to a history of MBO or IBD were 3.5%, 4.6%, and 5.7% in the United Kingdom, Spain, and Sweden, respectively.

CONCLUSIONS

Potential linaclotide off-label use and misuse appears limited, as evidenced by the small sizes of the patient subgroups at risk for off-label use and misuse.

Quality of life and sleep in individuals with irritable bowel syndrome according to different diagnostic criteria and inflammatory bowel diseases: A comparison using data from a population-based survey

BACKGROUND

A proportion of irritable bowel syndrome (IBS) affected patients does not fulfil Rome criteria despite considerable impairment similarly to that in patients with organic gastrointestinal diseases.This investigation aims to examine differences regarding Mental (MQoL), Physical Quality of Life (PQoL), and sleep between IBS according to Rome III (IBS Rome), clinically defined IBS, inflammatory bowel diseases (IBD), and non-IBS/non-IBD individuals.

METHODS

Data from SHIP-Trend (Study of Health in Pomerania, 2008-2012), a population-based cohort study in Germany, were used.

RESULTS

Response was 50.1% (N = 4420). Prevalence was 3.5% for IBS Rome (95% confidence interval (CI): 3.0 - 4.1%, n = 148), 0.6% for clinically defined IBS (CI: 0.4 - 0.9%, n = 27), and 0.8% for IBD (CI: 0.6 - 1.1%, n = 34). Individuals with IBS Rome (4.54 (CI: -5.92; -3.17)) and clinically defined IBS (4.69 (CI: -7.82; -1.56)) had lower scores for MQoL compared to the non-IBS/non-IBD group. PQoL scores were lowered in IBS Rome (6.39 (CI: -7.89; -4.88)) and IBD (5.37 (CI: -8.51; -2.22)), but not in clinically defined IBS compared to the non-IBS/non-IBD group. IBS Rome was the only gastroenterological condition with higher odds of sleeping problems (odds ratio (OR) "falling asleep": 1.74; CI: 1.29; 2.36; OR "remaining asleep": 1.73; CI: 1.26; 2.38).

CONCLUSIONS

IBS Rome is associated with reduced MQoL, PQoL, and sleep problems. Clinically defined IBS is associated only with reduced MQoL. Heterogeneity within IBS affected patients should be considered in clinical routine and screening for daily life impairment should be performed.

Symptomatic Treatment of Pain-Related Pediatric Functional Gastrointestinal Disorders in a Biopsychosocial Construct, and a Validity Study of Rome III Criteria

Our study aims to assess improvement with symptomatic treatment of pain-related functional gastrointestinal disorders (FGIDs) in a biopsychosocial construct and evaluate validity of Rome III criteria. Children with chronic abdominal pain diagnosed with an FGID or organic disease were followed for 1 year: 256/334 were diagnosed with an FGID and 78/334 were diagnosed with a possible organic disease due to alarm signs or not meeting Rome III criteria. After 1 year, 251 had true FGID and 46 had organic diseases. Ninety percent of FGID patients improved with symptomatic treatment over an average of 5.4 months. With a 95% confidence interval, Rome criteria predicted FGIDs with sensitivity 0.89, specificity 0.90, positive predictive value 0.98, and negative predictive value 0.59. We conclude that symptomatic treatment of pain-related FGIDs results in clinical improvement and could reduce invasive/expensive testing. Rome III criteria's high specificity and positive predictive value suggest they can rule in a diagnosis of FGID.

Importance of Non-pharmacological Approaches for Treating Irritable Bowel Syndrome: Mechanisms and Clinical Relevance

Chronic visceral pain represents a major unmet clinical need with the severity of pain ranging from mild to so severe as to prevent individuals from participating in day-to-day activities and detrimentally affecting their quality of life. Although chronic visceral pain can be multifactorial with many different biological and psychological systems contributing to the onset and severity of symptoms, one of the major triggers for visceral pain is the exposure to emotional and physical stress. Chronic visceral pain that is worsened by stress is a hallmark feature of functional gastrointestinal disorders such as irritable bowel syndrome (IBS). Current pharmacological interventions for patients with chronic visceral pain generally lack efficacy and many are fraught with unwanted side effects. Cognitive behavioral therapy (CBT) has emerged as a psychotherapy that shows efficacy at ameliorating stress-induced chronic visceral pain; however, the molecular mechanisms underlying CBT remain incompletely understood. Preclinical studies in experimental models of stress-induced visceral pain employing environmental enrichment (EE) as an animal model surrogate for CBT are unraveling the mechanism by which environmental signals can lead to long-lasting changes in gene expression and behavior. Evidence suggests that EE signaling interacts with stress and nociceptive signaling. This review will (1) critically evaluate the behavioral and molecular changes that lead to chronic pain in IBS, (2) summarize the pharmacological and non-pharmacological approaches used to treat IBS patients, and (3) provide experimental evidence supporting the potential mechanisms by which CBT ameliorates stress-induced visceral pain.

Knowledge and practices of primary care physicians or general practitioners treating post-infectious Irritable Bowel Syndrome

Background

Post-infectious Irritable Bowel Syndrome (PI-IBS) is a functional bowel disorder which has significant impacts to a patient’s quality of life. No IBS-specific biomarker or treatment regimen for PI-IBS currently exists, therefore understanding practice patterns and variance is of interest.

Methods

This online survey of primary care physicians and general practitioners in the USA aimed to understand the knowledge and treatment of PI-IBS within the physician’s current practice. Summary statistics are provided with a commentary on implications for practices and treatment of PI-IBS.

Results

Most physician survey respondents (n = 50) were aware of PI-IBS, but less than half discussed this condition as a possible outcome in their patients with a recent gastrointestinal infection. Most physicians indicated that they would treat the patients themselves with a focus on managing IBS through different treatment modalities based on severity. Treatment for PI-IBS followed IBS recommendations, but most physicians also prescribed a probiotic for therapy. Physicians estimated that 4 out of 10 patients who develop PI-IBS will have life-long symptoms and described significant impacts to their patient’s quality of life. Additionally, physicians estimated a significant financial burden for PI-IBS patients, ranging from $100–1000 (USD) over the course of their illness. Most physicians agreed that they would use a risk score to predict the probability of their patients developing PI-IBS, if available.

Conclusions

While this survey is limited due to sample size, physician knowledge and treatment of PI-IBS was consistent across respondents. Overall, the physicians identified significant impacts to patient’s quality of life due to PI-IBS.

Irritable Bowel Syndrome in a Population of a Developing Country: Prevalence and Association

Introduction: Irritable bowel syndrome (IBS) is included as one of the functional gastrointestinal (GI) related disorders presenting with pain in abdomen of chronic duration in the absence of any identifiable organic cause. Bloating, distension of abdomen, and defecation in disordered manner are other features commonly associated with IBS. It is a complex disorder with mixed physiological, psychological, and social interactions. The present study was carried out with the aim to determine the frequency of IBS in patients presenting with abdominal pain in a population of a developing country.

Materials and methods: A descriptive cross-sectional study was undertaken at the outpatient department of a large tertiary care hospital. Patients of either gender aged between 20 and 50 years presenting with abdominal pain were included. The diagnosis of IBS was established using Rome III criteria. Prevalence of IBS was calculated and confounding factors such as age, gender, marital status, duration of abdominal pain, and economic status were stratified to see their effect on outcome variable by applying chi-square test and taking p-value of <0.05 as significant.

Results: A total of 186 patients were included in this study. Some 100 (53.76%) were male and 86 (46.24%) were female. Mean age of the patients was 33.67 ± 7.08 years. Some 58.6% were married and 41.4% were single. Some 61.83% had mild abdominal pain and 38.17% had moderate pain. Out of the total 186 patients, the frequency of IBS was found to be 35.48%. There was no significant effect of confounding variables such as age, gender, duration of abdominal pain, marital status, and economic status on IBS.

Conclusion: In our study the frequency of IBS in patients with abdominal pain is high with no significant effect of gender, marital status, economic status, and duration of abdominal pain on IBS.

Community pharmacists' knowledge, attitude, and practice of Irritable Bowel Syndrome (IBS): the impact of training courses

Introduction: Irritable Bowel Syndrome (IBS) is a common chronic functional gastrointestinal disorder. Pharmacists have a vital role in patient education and in drug-therapy management for IBS. This survey is the first study in Iran, to evaluate knowledge, attitude, and practice (KAP) of community pharmacists on IBS, and the impact of training courses on the improvement of their skills. Objective and setting: This pre- and post-cross-sectional study was conducted to evaluate IBS-KAP amongst Community pharmacists in Shiraz, Iran. Methods: Pretested questionnaires were designed to assess professional characteristics and KAP components of the community pharmacists regarding IBS. All pharmacists from Shiraz were invited to participate in a 3-day training course on IBS. The participants were requested to complete the questionnaire before commencing the training course (pre-test), at the end of the 3-days course (post-test), and also 3 months after the course (follow-up test). Results: Correct answers to all parts increased after the training course, as well as in the follow-up stage, which was statistically significant in all three parts (P<0.05). The increases in correct answers were seen in the fields of attitude, practice, and knowledge. Conclusion: It seems that continuing IBS training courses are essential for pharmacists, regarding the fact that they can play an important role in assisting patients with IBS, as they are easily accessible healthcare professionals.

The "Biology-First" Hypothesis: Functional disorders may begin and end with biology-A scoping review

While it is generally accepted that gastrointestinal infections can cause functional disturbances in the upper and lower gastrointestinal tract-known as postinfectious irritable bowel syndrome (PI-IBS) and functional dyspepsia (PI-FD)-it has still not been widely recognized that such an infection can also initiate functional non-intestinal diseases, and that non-intestinal infections can provoke both intestinal and non-intestinal functional disturbances. We conducted a scoping review of the respective literature and-on the basis of these data-hypothesize that medically unexplained functional symptoms and syndromes following an infection may have a biological (genetic, endocrine, microbiological) origin, and that psychological and social factors, which may contribute to the disease "phenotype," are secondary to this biological cause. If this holds true, then the search for psychological and social theories and factors to explain why one patient develops a chronic functional disorder while another does not is-at least for postinfectious states-misleading and detracts from exploring and identifying the true origins of these essentially biological disorders. The biopsychosocial model may, as the term implies, always begin with biology, also for functional (somatoform) disorders.

Combining Rome III criteria with alarm symptoms provides high specificity but low sensitivity for functional gastrointestinal disorders in children

AIM

This study aimed to validate the Rome III criteria and alarm symptoms with regard to their ability to discriminate between organic and functional diagnoses in children with gastrointestinal complaints.

METHODS

We recruited 258 children aged four years to 17 years who consulted a paediatrician in secondary or tertiary care in Stockholm from January 2013 to May 2014 due to gastrointestinal complaints. A symptom questionnaire based on the official Questionnaire on Pediatric Gastrointestinal Symptoms Rome III, including questions on alarm symptoms, was used. A diagnostic review of their medical records was also carried out.

RESULTS

The reference diagnoses were organic (16%), pain-predominant functional gastrointestinal disorders (54%) and other functional diseases (30%). When the reported symptoms that fulfilled the Rome III criteria for pain-predominant functional gastrointestinal disorders were combined with an absence of alarm symptoms, they had a high specificity (0.90) for a functional diagnosis, but a low sensitivity (0.15). Alarm symptoms were equally common in patients with organic (83%) and functional diseases (80%, p = 0.66).

CONCLUSIONS

Combining the Rome III criteria and an absence of alarm symptoms from patient questionnaires had high specificity but low sensitivity when diagnosing pain-predominant functional gastrointestinal disorders in children seeking medical care for gastrointestinal complaints.

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.
