Plain English Summary
Background and study aims
The purpose of this study is to find out the possibility of integrating a new liver diagnostic pathway in GP practices using a liver health nurse in the practice team and a risk assessment tool. The aim is to improve upon patient outcomes and reduce costs in the early detection, diagnosis and treatment of patients with liver conditions within GP practices.
Who can participate?
Patients will be approached by the participating practices to attend clinic for a liver health check-up.
What does the study involve?
The practices will be randomly allocated to either the control group or the intervention group. Patients with suspected liver disease will be invited to undergo a liver health check performed by a liver health nurse. Intervention group practices will direct their patients for further investigation and disease management with the specialist supervisors of the study and their own General Practitioners. We anticipate that this level of access to specialist liver experts will be the same to attending a liver clinic with all the benefits involved.
What are the possible benefits and risks of participating?
There are no guaranteed benefits to participants from taking part in this study, however there is a small chance that their liver might be unhealthy or damaged. If this is the case, by taking part in this study they will find out more about the health of their liver.
Where is the study run from?
This study will take place in selected GP practices in Southampton and is being coordinated by the University of Southampton, UK.
When is study starting and how long is it expected to run for?
The study will start in November 2013 and it will run for 2 years in the practices.
Who is funding the study?
This study is funded by the British Liver Trust, UK.

Study information
Scientific title
A community based study to determine the feasibility of remodelling the diagnosis and management of liver disease in primary care to improve patient outcomes and reduce service delivery costs
Acronym
LOCATE
Study hypothesis
LOCATE is a cluster randomised service intervention in a primary care setting. The primary objective is to evaluate the feasibility of integrating a new diagnostic pathway in primary care with the implementation of a liver health nurse and a liver risk stratification tool. The secondary objective is to determine if the new pathway improves the effectiveness of the detection and management of chronic liver disease and leads to improved long-term outcomes together with the net NHS costs.
10 GP practices will be randomised to either the intervention or control arm. Both groups will undertake two audits of liver care, one before the intervention and one after.

Condition
Topic: Primary Care Research Network for England; Subtopic: Not Assigned; Disease: All Diseases
Intervention
Control: The practices randomised to the control arm will follow their existing local map of medicine.
Prior to randomisation, all practices will undertake an audit of liver care at their site.; Intervention, The intervention practices will receive the services of a liver health nurse, who will facilitate three intervention modules:
Intervention Module 1
Improved access to liver health assessment for incident liver abnormalities arising from routine care.
Intervention Module 2
Nurse led case finding using data already available in the clinical records to identify those at risk of significant liver disease.
Intervention Module 3
Nurse led population screening for excess alcohol use using t; Study Entry : Other; Details: Identified in an initial audit of liver care and contacted with a letter and information leaflet.

Eligibility
Participant inclusion criteria
Pre-Intervention Audit and Post-Intervention Audit
1. Elevated ALT (above ULN), other abnormal liver function test (Alk Phos or bilirubin above ULN, or Albumin <LLN) or new diagnosis of liver disease coded on the GP system within a twelve month period between the last 18 and 6 months.
Intervention Module 1
1. Clinical liver disease
2. Any patient newly identified by the practice with suspected liver disease in the one year of the prospective phase.
Intervention Module 2
1. All patients identified with a positive cTL on tests in the previous 6m
A sample from each of the following groups:
1. pre-existing abnormalities in liver function but without liver diagnosis and management plan identified in the practice audit
2. Type 2 diabetes
3. obesity BMI > 40 and no type 2 diabetes
4. patients with clinical record suggestive of hazardous alcohol use will be enrolled in Module 3 where appropriate
Intervention Module 3:
1. A sample(1000) of patients aged 30 to 65 together with any patients with suspected alcohol misuse from clinical records will be sent a postal invitation as part of the practice liver health programme. The invitation will include an AUDIT questionnaire
2. WHO AUDIT score either > 15 or >7 with alcohol intake on 4 days or more (AUDIT Q1), and alcohol intake of 7 units or more on a drinking occasion (AUDIT Q2) or estimated weekly alcohol intake > 28 units.
