Please note the ANZCTR will be unattended from Friday 20 December 2019 for the holidays. The Registry will re-open on Tuesday 07 January 2020. Submissions and updates will not be processed during that time.

Please be advised that as the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is 3 months in duration for each study participant. There will be 2 face-to-face visits at the beginning and completion of the intervention, with 4 phone consultations in between. It is expected that the face-to-face visits will take approximately 30 minutes in duration.

The intervention is a nurse-led support package which contains the following components:

1. An electronic decision support (EDS) tool

A mobile enabled web app designed to facilitate a discussion between the nurse and study participant and to build an individual patient profile. The app will be used by the nurse to take the participant through potential risk factors, lifestyle factors and medication options. The profile is based on the their stroke risk (using the CHAD2S2-VASc score), their medication adherence (using Morisky medication adherence score) and their cardiovascular risk factors and lifestyle choices. The app will be used at baseline and at the 3 month face-to-face follow up visit.

2. Health counselling and goal setting

At the baseline visit, the nurse will provide education and the pathophysiology of AF, its symptoms and possible complications. The nurse will discuss rate and rhythm control as well as prophylactic vascular therapy (including strict anti-coagulation monitoring) and information about knowing when to report to hospital. Each study participant randomised to the intervention arm will also receive a booklet entitled “Living with Atrial Fibrillation”.

At the baseline visit the nurse will provide behaviour change support, through motivational interviewing principles (Miller & Rollnick, 2012) and use the EDS tool to facilitate the discussion about HR-QoL encouraging patients to set realistic goals in line with their priority and motivation.

3. Three-month telephone-based support and follow up

The study participant will receive regular telephone support (minimum of four phone calls in the intervention period) and the nurse will continue to provide psychosocial support and educational interventions as offered at the baseline visit. The length of each phone call will be recorded in the Case Report Form (CRF).

The final face-to-face visit (3 months after the baseline visit) will collect the same individual patient data as collected as baseline including but not limited to vital sign measures, quality of life measures, and medication adherence.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants identified by medical physicians will be invited by the study team to attend a study visit. At the baseline visit participants will receive detailed information about the study and sign informed consent if willing to proceed. All consented participants will have the following information collected: review against inclusion/exclusion criteria, documented diagnosis of AF, relevant vital sign measures (heart rate, blood pressure) and cardiovascular risk factor measure (BMI, smoking status, alcohol consumption, physical activity level). All participants will be randomised via a central computer generated randomisation process.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned to either control or intervention group with a 1:1 allocation as per a computer generated randomisation schedule using permuted blocks of random sizes. The block sizes will not be disclosed, to ensure concealment.

Efficacy
Statistical methods / analysis
Primary analyses will be conducted using SPSS for Windows. Continuous variables will be reported as mean plus/minus standard deviation (SD), and categorical variables as numbers and percentages. Within subject differences between baseline and follow-up will be analysed using Wilcoxon signed ranks tests for non-parametric variables. Between group comparisons will be analysed using Student's t-test, the Mann Whitney U test (for non-normally distributed continuous data) and the chi-squared test (with calculation of odds ratios and 95% CIs) where appropriate. SF12 data will be analysed using software by OptumInsight.
Process evaluation interviews will be analysed using an inductive approach.

Summary
Brief summary
The study is a single blind randomised controlled trial to determine whether a nurse-led clinic which uses a mobile enable web app (a computer program that also works on a smartphone or tablet) to guide discussion between the nurse and patient, can improve lifestyle risk factors and health related quality of life (HR-QoL) in participants with AF. The study aims to provide evidence of feasibility with the intention to seek funding for a larger study.
