Description of intervention(s) / exposure
This is a prospective study to identify and risk-stratify nonalcoholic fatty liver disease (NAFLD) in people with type 2 diabetes (T2D). Sequential participants will be recruited to the NAFLD-RRR model of care, and then followed for up to 10 years to monitor their health outcomes. The detection of patients with NAFLD ± advanced fibrosis and the surveillance for hepatocellular carcinoma (HCC) among “high-risk” patients will be compared to a historical sample of patients receiving “usual care”. The study will be conducted by a study nurse and liver fellow/student in diabetes clinics in addition to usual care (diabetes specialist review).

The starting event is a patient scheduled for consultation in a Diabetes clinic. The study nurse will review the clinic list for each Diabetes clinic and briefly review the patient referral letter or clinic notes to identify patients that meet exclusion criteria.
Scheduled patients will be invited to be screened for NAFLD when they attend a Diabetes clinic appointment, using FibroScan to assess steatosis (CAP score) and liver fibrosis (liver stiffness measurement, LSM). The invitation and assessment will be made by a specialist study nurse and/or liver fellow. The NAFLD screening assessment, including FibroScan and additional blood tests are anticipated to take 30 minutes to complete.

At the FibroScan assessment the nurse and/or liver fellow will also assess:
• Girth, alcohol consumption (using a brief AUDIT), and simple algorithms (FIB-4 and NAFLD fibrosis score) using recent routine blood test results.
• A fasting blood test (up to 30ml) may be arranged for research purposes (this could be done when the diabetes doctor asks for a fasting blood test).
• If relevant blood tests are not available within the last 6 months, the liver nurse will arrange blood tests (E/LFTs and FBC). Results will be followed up by liver fellow.
• If liver enzymes are abnormal or LSM >/=8 kPa, additional blood tests (iron studies, hepatitis C and B serology, ANA, smooth muscle Ab, antimitochondrial Ab, anti-TTG) will be arranged. Results will be followed up by liver fellow.

The study nurse will complete a template letter with the results of the FibroScan that will be sent directly to the Diabetes specialist with the patient after the procedure. A letter will also be sent to the patient’s GP and a copy of the FibroScan report will be scanned into the patient’s electronic medical record (iEMR). These templates will be designed specifically for the study.

The patient will be diagnosed with NAFLD on the basis of the FibroScan CAP score (CAP score >/=248 dB considered as likely steatosis) and stratified to low or high risk of clinically significant fibrosis on the basis of the FibroScan liver stiffness measurement (LSM).

No NAFLD: Participants with CAP score <248 dB and LSM<8 kPa will be classified as “no NAFLD”. A letter (with a copy to iEMR) will be sent to the patient’s GP and diabetes specialist advising a repeat FibroScan or liver ultrasound in 3-5 years if appropriate, to screen for development of NAFLD.

NAFLD with Low risk of clinically significant fibrosis: Participants with CAP score >/=248 dB and low FibroScan score (LSM < 8.0 kPa) will be classified as ‘Low Risk’. A letter (with a copy to iEMR) will be sent to the patient’s GP and diabetes specialist advising a repeat FibroScan in 2-3 years if appropriate, to assess for development of clinically significant fibrosis.

NAFLD with High risk of clinically significant fibrosis: Participants with CAP score >/=248 dB and elevated FibroScan score (LSM >/=8.0 kPa) will be classified as ‘High Risk’. The Liver Nurse will advise patient (and GP and diabetes specialist via letter, along with a copy to iEMR) that Hepatology referral recommended and arrange Hepatology Clinic consultation.
Participants with a low CAP score and elevated LSM will also require Hepatology referral for further evaluation of possible clinically significant fibrosis.

The recommendations will be provided in the summary letter to the GP and diabetes specialist which will be designed specifically for this study. The letter will contain for each patient the results of their FibroScan with a CAP score and LSM. It will also contain a summary of the recommendations and will have a standard format for each category of: no NAFLD, NAFLD with Low risk of clinically significant fibrosis, NAFLD with High risk of clinically significant fibrosis. If advanced fibrosis is confirmed in the secondary care hepatology clinic, the patient may be offered ongoing hepatology follow-up that may involve HCC and variceal surveillance programs.
For all patients with NAFLD, the letter to the GP and diabetes specialist will provide recommendations regarding management of NAFLD with ongoing assessment and management of cardiometabolic risk factors and lifestyle intervention with consideration of referral to a dietician, exercise physiologist and psychologist for assistance with weight management and increased physical activity.

Comparator / control treatment
The outcomes from the study will be compared with data collected previously from patients receiving “usual care”, which does not involve standardised procedures for assessing and managing NAFLD in primary care. The medical records of patients attending Diabetes clinics over the preceding 12 months will be audited to determine the number of patients with a recorded diagnosis of NAFLD and whether an assessment of liver disease severity was performed.

3 years post-intervention commencement.
Secondary outcome [1] 390345 0
Number of participants with ‘high-risk’ NAFLD diagnosed using FibroScan, defined as liver stiffness measure (LSM) greater than or equal to 8.0 kPa on FibroScan, that were referred to secondary care (Hepatology) based on the study intervention.

Secondary outcome [2] 390347 0
Number of unnecessary referrals to secondary care. Unnecessary referrals are defined as patients with ‘low risk’ NAFLD with a TE less than or equal to 8.0 kPa. This will be assessed using patient medical records.
Timepoint [2] 390347 0
3 years post-intervention commencement.
Secondary outcome [3] 390348 0
Assess the rate of surveillance for HCC among ‘high-risk’ patients with NAFLD. This will be calculated based on the number of participants diagnosed with advanced fibrosis/cirrhosis following clinical assessment by a Hepatologist, who receive liver imaging, usually ultrasound, every 6 months. This will be assessed using data-linkage to patient medical records.

3 years post-intervention commencement.
Secondary outcome [4] 390349 0
Cost analysis of the NAFLD detection/risk stratification pathway in patients with type 2 diabetes. Will be assessed by calculating the difference in resource use and costs before and 3 years post-intervention commencement, from hospital medical records, patient out-of-pocket costs and MediCare Statistics.

Assessment of patients’ supportive care needs:
The type and level of perceived supportive needs of people living with advanced liver disease (assessed with FibroScan with TE greater than or equal to 8.0 kPa) secondary to NAFLD, will be assessed using the Supportive Needs Assessment tool for Chronic liver disease (SNAC).

Statistical methods / analysis
Data analysis will be largely descriptive; that is, we will report means, proportions, and measures of variance. Differences in the proportion of patients (i) diagnosed with NAFLD (ii) identified to have clinically significant fibrosis (iii) referred to Hepatology with “high-risk” vs. “low-risk” disease, and enrolled in a surveillance program for HCC before and after implementation of the intervention will be assessed using statistical tests for categorical data (e.g. Pearson’s chi-squared test, McNemar test). Where appropriate we will use regression models to identify associations between variables. For example, we may assess the association between treatment group (intervention vs. usual care) and clinical and sociodemographic factors.
