Description of intervention(s) / exposure
Research Aim: The aim of this study is to explore the impact of general practice-initiated SMS recall messages (with and without an additional nudge message) on increasing attendance at GP clinics and increasing CVD risk assessment.

Research setting: The trial will be initiated via text mediated message sent by participating general practices across the country. Practices in one arm will be asked to send a second nudge message 2 weeks after the recall message is sent. CVD risk assessment and management will be undertaken within the practice and as part of the individual's routine medical care

Methodological approach:
The trial design will be a multiple-armed randomised control trial (RCT). The level of analysis will be general practice clinics.
Practices will be randomised into two intervention arms and 1 control arm. The intervention arms are as follows:
1. Active arm 1 (recall only message) will be provided with an information package (constituting a recall SMS with an embedded link to cardiovascular health promotion resources) to be sent to patients who are eligible for cardiovascular disease screening.
2. Active arm 2 (recall + nudge message) will be provided with an information package (constituting a recall SMS and an additional nudge SMS message, both with embedded link to cardiovascular health promotional resources to send to patients who are eligible for cardiovascular disease screening. There will be a two-week period between the sending of the recall and nudge message. The first recall SMS will be triggered manually via the GoShare Plus software followed by an automated nudge message 2 weeks later.

A 12 week observation period applies for both intervention arms, with a follow up three-month data report extracted at completion of observation period.

Recall text messages will be sent in bulk via GoShare Plus software (add on to clinical practice software) by relevant staff within the participating general practice e.g. GP, practice nurse or practice manager.

Both the recall and nudge message content will be between 200 - 230 characters long and broken into two sentences. We anticipate the reader will engage with the message for no longer than 1 minute. If the reader chooses to select the embedded link for more information, we anticipate the reader could spend between 3 to 5 minutes depending on the reader’s interest. The landing page content will include summary of information already available via the National Heart Foundation website, and includes:
• Summary information adapted from ‘Time to book a Heart Health Check’ webpage.
• Pre-existing animation, available on the ‘Time to book a Heart Health Check’ webpage’
• Two pre-exisiting patient stories, that has been used via National Heart Foundation consumer social media channels, campaigns and consumer facing e-newsletter. Both patient stories are selected from the ‘Heart Stories’ webpage
• Summary description and link to the consumer developed ‘Heart Age Calculator’

Recall and nudge message reach and content engagement with the content will be reported using a live dashboard developed by Healthily who have developed the GoShare Plus technology. The Dashboard will report on the number of SMS sent, the open rate per practice, the open rate of SMS landing page links per practice and the number of content views.

Behaviour
Comparator / control treatment
An active control group will consist of randomly allocated general practices who do not send out recall messages. The control arm will be asked to maintain care-as-usual for the 12 week observation period.

Following the 12 week observation period, the practices in the control arm will be provided with all materials and support provided to the active arm allowing them to provide identical information to their patients. At that point, control practices will be given the opportunity to choose if they want to send recall or recall + nudge as an intervention.

Eligibility
Key inclusion criteria
We will aim to recruit 200 general practices across Australia to participate in this trial. General practice inclusion criteria:
• General practices must have accreditation from one of the five Australian accreditation agencies recognised by the RACGP – AGPAL, Quality Practice Accreditation, Australian Council on Healthcare Standards, Global-Mark Pty Ltd or Institute for Healthy Communities Australia Certification Pty Ltd.
• Practices must be using CAT4 with Best Practice, Medical Director, Zedmed, Genie, Medtech, practiX, Communicare, MMEX or PCIS software.
• Practices must allow Healthily to enable GoShare Plus functionality in CAT4.

As part of the study, general practices in intervention arms 1 (recall only) and 2 (recall and nudge) will use GoShare Plus software to send Heart Health Check recall SMS to their eligible patients asking them to come in for cardiovascular screening. Eligible patients who will be identified via practice software:
• Aged 45 to 74 years
• No recorded diagnosis of existing CVD, and
• No health assessment or Heart Health Check in the last 24 months, and
• No recorded total cholesterol to HDL ratio (TC:HDL) in the last 24 months, and
• Active patient of the practice based on RACGP definition of active patient (at least 3 visits in the last 2 years)

Efficacy
Statistical methods / analysis
A power calculation was undertaken to estimate the minimum number of practices required to conduct a three-armed study observing changes in the number of CVD risk screening activities undertaken, as measured by Heart Health Checks (HHCs); MBS items 699 and 177.
Based on our prior study (RACGP ethics application #20-047), manuscript in preparation) the number of HHCs undertaken in a three-month period was nominated as 6.8 (s.d. 16.5). This was derived from the control population in this study. An impact of the SMS recall message was estimated at a 150% increase (IRR of 2.5). This is based on a large observed effect (IRR of 13) in the prior study. An impact of the nudge message was estimated to cause a 30% increase in the number of HHCs undertaken.
Based on these assumptions the total sample size required to detect a difference is 75 (25 practices x 3 arms). As the targeted recruitment is 200 this will allow substantial overhead for potential loss to follow up/dropout. If maximum recruitment is achieved, and there is limited dropout or loss to follow up, detection of effect sizes smaller than those assumed above will be possible.

Summary
Brief summary
This study will explore the impact of general practice-initiated SMS recall messages (with and without an additional nudge message) on increasing attendance at GP clinics and increasing CVD risk assessment.
The trial design will be a three-armed randomised control trial. The level of analysis will be general practice clinics. Practices in the two active arms will be provided with an information package (constituting a recall SMS with an embedded link to health promotion resources) to be sent to appropriate patients Active arm 2 will be provided with an additional nudge message (with embedded link to health promotion material) to be sent two weeks after the recall message is sent. The control arm practices will be asked to maintain care as usual for a three-month follow up period. Following the 3 month observation period, the practices in the control arm will be provided with all materials and support provided to the active arm allowing them to provide identical information to their patients. The practices will be randomised using a pseudo random number generator (RNG) to assign participating practices to one of three groups.
