Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention consists of:-
1. A training workshop for General Practitioners (GPs) and Practice Nurses (PNs) on prevention of vascular disease. The workshop is of 3 hours duration and is overseen and presented by a Primary Health Care specialist and Clinical Investigator in each state, the Intervention Facilitator (IF) and a Division of General Practice/Medicare Local staff member. The workshop introduces the 5As (Assess, Advise/Agree, Assist/Arrange) for smoking, nutrition, alcohol, physical activity, weight, blood pressure, cholesterol, diabetes, absolute cardiovascular risk and kidney disease. The format of the workshop is an introductory presentation followed by case studies and role plays using simulated patients.
2. Three practice visits of approximately 1-1.5hours duration each over 4 months will be provided by an intervention facilitator. The practice visits are designed to occur at regular intervals during the intervention period
a) Practice visit 1 - 4 weeks post workshop
b) Practice visit 2- 3-4 weeks after visit no 1
c) Practice visit 3 - 3-4 weeks after visit no 2
During the 4 months period the IF will also conduct 3 follow-up and troubleshooting phone calls with a member of the practice staff identified at visit no 1 to act as the 'prevention coordinator'


This meeting with the practice staff is designed to:
a) Review the baseline clinical audit report and identify areas for improvement
b) Set some goals and plan for improvement
c) Provide resources, referral links or support to help the practice
d) Monitor improvements

The training for GPs and PNs is designed to highlight the guideline recommendations relating to preventive activities in general practice. The practice is given baseline data which allows them to identify deficits in meeting these guideline recommendations and guided to identify ways in which they can modify their practice to deliver appropriate preventive care to their patients. Patients will receive the usual care of their practitioner but we would envisage that this care will be modified reflecting guideline recommendations provided through the training and additional resources.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
General practices are enrolled in each state by a Field Research Officer/Intervention Facilitator who obtain consent for participation. Consented practices are forwarded to a central administration site (University of NSW) where the randomisation is carried out (see below)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation is conducted at the level of the practice (cluster) using block randomisation, stratified according to practice size using a computer generated randomisation program. Randomisation is performed by a person independent of the data collection and intervention
Masking / blinding

Summary
Brief summary
The PEP study is a partnership between New South Wales, Flinders, Monash, Bond and Queensland Universities, the Royal Australian College of General Practitioners (RACGP), the National Heart Foundation of Australia (NHFA) and the BUPA Foundation.

The study is in response to the need to evaluate the uptake and effectiveness of current guidelines for the prevention of chronic disease in general practice, and to develop innovative and effective implementation strategies for the future.

The aims of this partnership are to design, trial and evaluate a framework to improve the implementation of the RACGP, the NHFA and NHMRC guidelines for prevention of chronic disease in general practice.
