Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will receive regular semi-personalized lifestyle reminders sent via mobile phone text messages for 6 months. Each participants will receive 4 text messages per week for 6 months. These will be sent at random times of the day (9.00am, 12noon, 3.00pm, 5.00pm) and on random days of the week (Monday through Friday). Non-smokers will receive two general messages, one nutritional message and one physical activity message per week. Smokers will receive one general message, one nutritional message, one physical activity message and one smoking cessation message per week. Messages will be practical in nature, less than 160 characters in length and will be generic for varying age and genders. Prior to study commencement, a bank of 100 messages will be developed based on scientific literature and multidisciplinary expert review and finalised via a qualitative review process.

Comparator / control treatment
Treatment Group: Participants in the treatment group will receive repeated semi-personalized lifestyle reminders sent via mobile phone text messages for 6 months

Control Group: Participants in the control group will participate in "usual care". Usual care will include ongoing management by the patient's treating doctor/s including potential pharmacotherapy and lifestyle counseling as determined by their usual doctors.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be approached directly by the research assistant during a very brief face to face meeting during the inpatient stay. The researcher will establish whether the patient is interested in volunteering and if they consent they will be randomised.
The patients will be allocated by central randomisation by computer and the on site staff will not have access to the details of randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by computer software (computerised sequence generation).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Summary
Brief summary
To establish the feasibility, patient acceptability, effect on risk factors and thereby overall potential of repeated semi-personalized lifestyle reminders sent via mobile phone text messages in a population at high risk of cardiovascular events.
The main hypothesis that will be tested is that a program of brief and repeated lifestyle messages will improve cardiovascular risk factor levels compared to usual care.
