Systematic Review: Integrated Models of Care for Managing Irritable Bowel Syndrome.

BACKGROUND

Multidisciplinary integrated models of care show promise for improving symptoms and quality of life (QoL) in adults with irritable bowel syndrome (IBS).

AIMS

To describe and evaluate the characteristics of integrated models of care for IBS and identify how digital health is being used in these models of care.

METHODS

Four databases were searched to March 2024 for studies that included adults with IBS who participated in multidisciplinary integrated models of care that delivered non-pharmacological therapies. The template for intervention description and replication (TIDieR) checklist was used to appraise study quality and extract model of care characteristics, which were mapped against the Project INTEGRATE framework to establish topics.

RESULTS

Sixteen studies (6 randomized controlled trials, 2 quasi-experimental, 8 cohort studies) reported 14 integrated models of care including 2165 patients of which 918 were IBS patients. Integrated models of care led to improved IBS symptoms (n = 11/13 models of care) and QoL (n = 6/9 models of care). Studies showed moderate compliance with the TIDieR checklist. Five topics were established: clinicians involved, therapies provided, location and mode of delivery, coordinating clinical partnerships, and sharing visions and values of integrated care. Most commonly, a gastroenterologist coordinated care with a psychologist, dietitian, and/or nurse in tertiary care. Psychological, dietary, and physical therapies were provided by n = 11, n = 8, and n = 3 integrated models of care, respectively. Six models of care provided joint consultations or group sessions. Four models of care used digital health such as telephone coaching or online modules.

CONCLUSIONS

Integrated models of care for IBS exhibited diverse characteristics including the clinicians involved, the therapies provided and the mode of delivery of each therapy. There is a need to evaluate the use of digital health and the delivery of integrated models of care in primary care settings.
