ADAPT: Acceptability of online dietary assessment of irritable bowel syndrome (IBS) patients in clinical practice

INTERVENTION: A sample between 80 and 100 patients diagnosed with IBS will be randomly allocated (1:1) to web‐based 24‐hr dietary recalls or routine dietetic practice (dietary history interview method) and followed for 6 months. Patients allocated to the intervention will be invited to complete at least two 24‐hr dietary recalls prior to the dietetic appointment (one‐to‐one consultations or group sessions). This will provide 1) quantified online dietary feedback upon completion of each recall for the patient’s review, and 2) upload of detailed dietary results report to the patient’s electronic medical notes for the dietitians’ review to tailor dietary advice to patients during one‐to‐one consultations. Current routine dietetic practice uses dietician‐led diet history interviews during one‐to‐one consultations or no dietary assessment for group sessions. All IBS patients enrolled in the study will be invited to complete web‐based 24‐hr dietary recalls prior to initial dietetic consultation and at end of the study (6 months). CONDITION: Irritable bowel syndrome (IBS) ; Digestive System PRIMARY OUTCOME: IBS adequate relief and symptom severity score measured by IBS symptoms questionnaire at baseline, monthly, within 2 weeks pre‐dietetic appointment, discharge and end of study time points. SECONDARY OUTCOME: ; 1. Adherence to dietetic advice ‐ measured by IBS symptoms questionnaire at baseline, monthly, within 2 weeks pre‐dietetic appointment, discharge and end of study time points.; 2. Quality of dietetic practice ‐ measured by Satisfaction, acceptability and Quality of Care questionnaire at the discharge timepoint. Also measured using information from CUH electronic medical notes at at baseline, monthly, within 2 weeks pre‐dietetic appointment, discharge and end of study time points.; 3. Response rates and acceptability of dietary assessment methods ‐ measured by Satisfaction, acceptability and Quality of Care questionnaire at the discharge timepoint.; 4. Quality of life (IBS specific) ‐ measured by IBS Quality of Life questionnaire at baseline, discharge and end of study timepoints.; 5. Dietetic consultation time (for one‐to‐one consultations only) ‐ measured using information from CUH electronic medical notes at at baseline, monthly, within 2 weeks pre‐dietetic appointment, discharge and end of study time points.; 6. Frequency of follow‐up dietetic consultations (for one‐to‐one consultations only) ‐ measured using information from CUH electronic medical notes at at baseline, monthly, within 2 weeks pre‐dietetic appointment, discharge and end of study time points.; INCLUSION CRITERIA: 1. Newly admitted patients older than 18 years 2. Meet the ROMEIV criteria for IBS diagnosis according to the National Institute of Health and Care Excellence (NICE) guidelines
