Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment of patients as outpatients under the care of the Hospital in the Home (HITH) team. Groups will be treated in one of two treatment arms, either with intravenous antibiotics or oral antibiotics.

IV antibiotics: Ceftriaxone 1g once daily, Metronidazole 500mg twice daily. (Three days total)
Oral antibiotics: Augmenting Du Forte 875mg/125mg twice daily. (Five days total).

Visits by HITH team members to ensure compliance.

Treatment: Other
Comparator / control treatment
Patients will be treated at home with the HITH team with either intravenous antibiotics or oral antibiotics. The reference group will be the IV antibiotic group.
Control group
Active

Outcomes
Primary outcome [1] 304707 0
Time to resumption of pre-morbid function. This will be assessed by a study specific questionnaire provided to the study participants that will be returned to the study coordinators during the first follow-up appointment.
Timepoint [1] 304707 0
Two weeks post commencement of intervention.
Secondary outcome [1] 342895 0
Re-presentation to hospital: study coordinators will be notified when a patient represents to ED and will be assessed as to whether they have represented due to their diverticulitis or other reasons. The re-presentation rate will assess the safety/efficacy of treating patients in the community with HITH versus as inpatients in hospital.
Timepoint [1] 342895 0
Two weeks post commencement of intervention.
Secondary outcome [2] 349160 0
Biochemical markers: assessed via laboratory testing. Blood samples will be collected by the HITH team during their visits. Key tests include a patients white cell count and CRP.
Timepoint [2] 349160 0
Two weeks post commencement of intervention.
Secondary outcome [3] 349161 0
Pain scores. Patients will be recording daily pain scores. Data will be collected via patient diaries and questionnaires.
Timepoint [3] 349161 0
Two weeks post commencement of intervention.
Secondary outcome [4] 349162 0
Patient satisfaction. Patients will be asked how satisfied they were with their treatment. Data will be collected via patient diaries and questionnaires.
Timepoint [4] 349162 0
Two weeks post commencement of intervention.
Secondary outcome [5] 349163 0
Time to return to normal diet/bowel habit. Data will be collected via patient diaries and questionnaires.

Safety/efficacy
Statistical methods / analysis
Statistical analysis will be performed on the data collected to determine if outpatient management via HITH of uncomplicated acute diverticular disease is as safe, effective and results in higher patient satisfaction than current inpatient management.

A cost comparison will also be performed looking at the average cost per day and the average cost per admission between participants in the inpatient treatment group and the HITH treatment group.

This statistical analysis will involve the calculation of simple percentages comparing the outcomes obtained between the two groups with t-test analysis. An independent statistician will be recruited to assist in data analysing and statistical analysis.

Summary
Brief summary
Aim: To determine if outpatient management (via Hospital in the Home [HITH]) of uncomplicated acute diverticular disease is as safe and effective.

Both groups will be treated as outpatients with the Hospital in the Home team.

Primary Endpoint: Time to resumption of normal activities of daily living.
Secondary Endpoints: Pain, Diet, Bowel habit, Patient satisfaction, Biochemical markers, Cost comparison.
