Abstract
INTRODUCTION: The BURDEN IBS-C study was conducted to better understand the experiences, attitudes, and unmet needs of sufferers of irritable bowel syndrome with constipation (IBS-C) in comparison to the perceptions and challenges of healthcare providers (HCPs) who treat IBS-C patients. METHODS: This was an author-developed, online questionnaire using KnowledgePanel(®) to survey individuals with IBS-C (N = 1311). HCPs participated in a complementary online questionnaire and were recruited separately (N = 331). The study was fielded from June 29, 2016, to January 30, 2017. RESULTS: Most patients had used (86%) and/or were using (76%) over-the-counter treatments for their IBS-C, with 12% currently on prescription therapy. At the time this study was conducted, 66% and 63% were not satisfied/completely satisfied with over-the-counter or prescription treatment, respectively, citing inadequate efficacy (55%) and side effects (39%), most commonly diarrhea, as common reasons for dissatisfaction. IBS-C respondents most commonly reported feeling frustrated (43%) and stressed (28%) regarding IBS-C, though 39% were accepting of IBS-C as part of daily life. HCPs were aligned with patients in thinking that patients were frustrated (76%) and stressed (65%) but HCPs were less likely to recognize that patients had become accepting of their IBS-C (13%). Most HCPs (79%) were not satisfied/completely satisfied with the prescription treatments available at the time this study was conducted. Inadequate response rates to current therapies (55%) and treatment adherence/compliance issues (58%) were the most frequent challenges encountered by HCPs. IBS-C respondents reported that their symptoms impacted productivity and personal activity, on average, 4 and 3 days/month, respectively. CONCLUSION: These results suggest that current management pathways may not be adequately addressing the symptoms and needs of individuals with IBS-C, most notably side effects and lack of efficacy. Patients and HCPs expressed dissatisfaction with over-the-counter and prescription treatments available at the time this study was conducted. Additional treatment options and improved dialogue would be beneficial to HCPs and patients. FUNDING: Synergy Pharmaceuticals Inc.
