BACKGROUND: Real-world data on the outcome of routine treatment for disorders of gut-brain interaction (DGBI) in secondary care are lacking.
METHOD: A longitudinal study of consecutive adult patients with various DGBI attending this institution's gastroenterology clinic was conducted. Following 2 years of treatment, the proportion of patients with symptom improvement, details of clinical therapy, factors associated with and the impact of 'no symptom improvement' were determined.
RESULTS: A total of 289 patients (median age 68 years; 64.7% females; 28.4% irritable bowel syndrome (IBS), 20.1% functional dyspepsia (FD), 8.7% functional constipation (FC), 42.9% overlap syndrome) were recruited. After 2 years, 66.1% patients reported symptom improvement. Patients with overlap syndrome were less likely to have symptomatic improvement compared to those with a single DGBI (Overlap 55.6% vs IBS 74.4% vs FD 72.4% vs FC 76.0%, p = 0.014). Reassurance was associated with symptom improvement (p < 0.001). On multivariate analysis, overlap syndrome remained significantly associated with a poorer outcome (OR 2.27, 95% CI 1.22-4.25, p = 0.010), while providing reassurance was associated with a positive outcome (OR 0.30, 95% CI 0.16-0.56, p < 0.001). Only 25.6% and 14.9% of patients were referred for a low FODMAP diet and psychiatric intervention respectively. DGBI patients who had 'no improvement' were more likely to seek further GI consultations and had more work absenteeism.
CONCLUSION: Two-thirds of DGBI patients in secondary care showed symptom improvement. Patients who were reassured had better symptom improvement, while those with an overlap syndrome were associated with a poorer outcome, resulting in greater healthcare consultation and work absenteeism.
