Background/objectives: To assess the impact of inpatient dietary prescription and dietary fibre intakepost-discharge on healthcare use and gastrointestinal symptoms in patients with acute, uncomplicated diverticulitis. Methods: Prospective observational study comparing inpatient restricted diet (n=31) andliberalised diet (n=29) of patients admitted to Robina Hospital, and low fibre diet (n=39) with high fibre diet (n=6) 30 days post-discharge. The primary outcomewas length of stay for assessing the impact of inpatient diet prescription. Outcomes for assessing the effect of outpatient diet were gastrointestinalsymptoms, readmission, reoccurrence and GP visits.Results: The mean length of stay for the restricted diet group was 4.02±1.10 days and 2.86±1.32 for the liberalised diet group (p=0.001). In a multiple regression analysis, when accounting for confounding variables, compared to a restricted diet, a liberalised diet had a significantly decreased length of stay of 0.91 days (95% CI: -1.714 to -0.119; p=0.02). There were no significant differences inreadmission, reoccurrence, GP visits and gastrointestinal symptoms between outpatient diet groups 30 days post-discharge. At 6 months postdischargethere were no significant differences in readmission for both inpatient and outpatient diet groups.Conclusion: This study found that a liberalised diet is associated with a shorter hospital length of stay compared to a restricted diet in patients with acute, uncomplicated diverticulitis. It has also been shown that a liberalised diet is safe in terms of diverticulitis reoccurrence, hospital readmission and gastrointestinal symptoms. This study was unable to support the efficacy of a high fibre diet in the management and prevention of diverticular disease
