This burden includes digestive symptoms and disease severity, as well as patients’ ability to cope with them. Chronic digestive diseases, such as irritable bowel syndrome, gastroesophageal reflux disease, and inflammatory bowel diseases, cannot be disentangled from their psychosocial context. In this regard, the role of gastroenterologists in promoting best practices for the assessment and referral of patients across the spectrum of disease to brain-gut psychotherapies is crucial.
A review by Laurie Keefer, PhD, AGAF, and her coauthors, published in the April issue of Gastroenterology, provided a clinical update on the structure and efficacy of two major classes of psychogastroenterology – cognitive-behavioral therapy (CBT) and gut-directed hypnotherapy (HYP). The review discussed the effects of these therapies on GI symptoms and the patients’ ability to improve coping, resilience, and self-regulation. The review also provided a framework to understand the scientific rationale and best practices associated with incorporating brain-gut psychotherapies into routine GI care. Furthermore, it presented recommendations on how to address psychological issues and make effective referrals in routine practice.
Previous studies had highlighted that the burden of chronic digestive diseases is amplified by psychosocial factors, including poor coping, depression, and poor social support. Mental health professionals specializing in psychogastroenterology integrate the use of brain-gut psychotherapies into GI practice settings, which may help reduce health care utilization and symptom burden.
The article contains best practice advice based on a review of the literature, including existing systematic reviews and expert opinions. These best practices include the following:
- Gastroenterologists routinely should assess health-related quality of life, symptom-specific anxieties, early-life adversity, and functional impairment related to a patient’s digestive complaints.
- Gastroenterologists should master patient-friendly language to help explain the brain-gut pathway and how this pathway can become dysregulated by any number of factors, the psychosocial risks perpetuating and maintaining factors of GI diseases, and why the gastroenterologist is referring a patient to a mental health provider.
- Gastroenterologists should know the structure and core features of the most effective brain-gut psychotherapies.
- Gastroenterologists should establish a direct referral and ongoing communication pathway with one or two qualified mental health providers and assure patients that he/she will remain a part of the care team.
- Gastroenterologists should familiarize themselves with one or two neuromodulators that can be used to augment behavioral therapies when necessary.
Patient education about the referral to a mental health provider is difficult and requires attention to detail and fostering a good physician-patient relationship. It is important to help patients understand why they are being referred to a psychologist for a gastrointestinal complaint and that their physical symptoms are not being discounted. Failure to properly explain the reason for referral may lead to poor follow-through and even lead the patient to seek care with another provider.
In order to foster widespread integration of these services, research and clinical gaps need to be addressed. Research gaps include the lack of prospective trials that compare the relative effectiveness of brain-gut psychotherapies with each other and/or with that of psychotropic medications. Other promising brain-gut therapies, such as mindfulness meditation or acceptance-based approaches, lack sufficient research to be included in clinical practice. Limited evidence supports the effect of psychotherapies have in accelerating or enhancing the efficacy of pharmacologic therapies and on improving disease course or inflammation in conditions such as Crohn’s and ulcerative colitis.
