Study type
Description of intervention(s) / exposure
Text messaging program will be implemented in addition to the current chronic disease rehabilitation programs in Sydney LHD. The semi-personalised messages (messages will include the participant's nickname), are sent 5 times per week, are based on behavioural psychology and provide self-management support relating to medication adherence, attendance at chronic disease programs, follow-up appointments and lifestyle change for six months. The message will contain information about smoking, diet, exercise and general info on the chronic disease the participant has been diagnosed with. The messaging program will be delivered according to our previously published model. Semi-personalised messages will be sent from a centralised web-based platform that provides simple registration and automated message delivery. Messaging software will be used to monitor whether participants open the messages or not.

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)
Single blinded, participants will know if they receive text messages, however they are encouraged not to inform the staff at the rehabilitation clinic.
Allocation is concealed as it is done by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will occur via a computer randomised program, allocation sequence will be in a 3:1 allocation ratio
Masking / blinding

Brief summary
Over 7 million Australians are living with a chronic conditions that cause more than half of all preventable hospital admissions. Once people leave hospital only about 50% adhere to prescribed medicines and at best 30% achieve lifestyle change. Simple strategies to improve ‘out-of-hospital’ management and support are needed. Text messaging has been shown to be effective and simple and is supported by quantitative and qualitative evidence led by CIs who have developed text message programs that promote lifestyle change. At the same time, Sydney Local Health District (LHD) has a text message system for contacting and following-up patients with chronic disease. However, these programs are not linked and in this research we will expand, refine and integrate our existing message programs then test and examine implementation. We propose a 3 phase project combining implementation science, a pragmatic trial, qualitative research and stakeholder engagement with appropriate ethical approval and following CONSORT guidelines. Phase 1 will see expansion of existing software and message content. Phase 2 is a pragmatic randomised implementation trial (n=310) with clinical and cost-effectiveness outcomes coupled with a process evaluation to inform scalability and implementation across settings. Phase 3 is a post-implementation assessment of success and challenges: to enable refinement of program content and features so as to maximise future success and ensure scalability.
