Description of intervention(s) / exposure
The Department of Gastroenterology and Hepatology at the Princess Alexandra
Hospital has recently established an Integrated Care Clinic as a strategy to help meet
the growing demands for Gastroenterology and Hepatology outpatient services, to
reduce waiting times and minimise risks to patients resulting from delayed health care
management. The Integrated Care Clinic provides a multi-disciplinary approach by
providing outpatient services cooperatively by GPs/specialists and nurses and well as
by allied health professionals including psychologists, dieticians and exercise
physiologists to manage patients with highly prevalent, but chronic conditions including
patients with functional gastrointestinal disorders such as irritable bowel syndrome (IBS)
as well as hepatology conditions such as non-alcoholic fatty liver disease (NAFLD).
This study is designed to compare the effects of standard care and the Integrated Care
Clinic on the health outcomes of patients in relation to psychological, dietary and activity
outcome parameters.

500 consecutive English-speaking patients diagnosed with Nonalcoholic Fatty Liver Disease (NAFLD) and Nonalcoholic Steatohepatitis (NASH), as well as stable Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS) will be will undergo routine
diagnostic work-up. Thereafter patients will be randomised to receive one of three
interventions:
Group One will receive the individualised integrated care model which includes
standardised assessment by a Gastroenterologist or Fellow, Psychologist, Dietician and
Exercise Physiologist and a Primary Care Physician (GP). Following the standardised
assessment, patients in Group one will receive a multidisciplinary integrated treatment
approach which will may include sessions by a Psychologist, Dietician, and Exercise
Physiologist as detailed under Integrated Care Model. The number of the treatment session will be determined by the individual clinicians to meet the patients needs. After
a maximum of 4 months patients with either return to standard care or discharge to their
GP.

Group Two will receive standard care which will include a standardised assessment
and routine management by a Gastroenterologist or Hepatologist. The treatment
approach will be defined during the case conference and the patients will receive in total
up to ten outpatient department (OPD) consultations with specialists, psychologists or allied health staff. After these 10 consultations, the patient is either discharged to the GP or continues to receive standard care in the OPD setting if this is deemed necessary by the gastroenterologists.

Group Three- Patients randomised to group three receive standard care in the OPD
setting. However, relevant outcome parameters will be collected 4, 12 and 26 weeks
after initiation of therapy.

Fatty Liver Disease (NAFLD), Nonalcoholic Steatohepatitis (NASH), stable Inflammatory
Bowel Disease (IBD), or Irritable Bowel Syndrome (IBS).
Minimum age

Efficacy
Statistical methods / analysis
We will compare the primary outcomes of the intervention groups with regard to a) GI
symptoms intensity (SAGIS), b) quality of life domains (SF-36), c) anxiety and
depression (HADS), d) physical activity (IPAQ) and e) work productivity (WPAI:GH)
using the unpaired t-test. Confounding is unlikely due to randomization however the
potential will be assessed and analysis of covariance used instead should it be
identified. Should the assumption of Normality not be met, statistical inference will
employ the non-parametric bootstrap. Statistical significance will be defined as p<0.017
to allow for multiple related outcomes.
