Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eligible registrants from the Australian Stroke Clinical Registry (AuSCR) randomised to the intervention group will receive one SMS during the follow-up period (90-180 days post-admission for stroke or TIA). Approximately 90 days post-admission, all eligible registrants will be sent the follow-up questionnaire by mail. Where no response has been received, an SMS will be sent four weeks following the mail-out of the questionnaire.

The SMS will invite the registrant to complete a follow-up questionnaire by clicking on a unique link. The follow-up questionnaire is identical to that which is currently used by the registry in a paper format, distributed by mail, and that can be completed over the telephone. It includes questions on where the registrant is living, whether they are living alone, if they have had another stroke or been readmitted to hospital, a self-reported measure of disability (modified Rankin Scale [mRS]) and EuroQol EQ-5D-3L for health and quality of life indicators. The approximate time estimated for the completion of the questionnaire is ten minutes.

Successful delivery of the SMS will be monitored.

If no response is received to the SMS, the registrant will continue the standard AuSCR follow-up process. This includes a second mail-out of the questionnaire to the registrant/next of kin approximately two weeks following SMS (six weeks following first mail attempt). If no response received six weeks later, the registrant/next of kin will be called to see if they would like to complete the questionnaire over the phone.

Treatment: Other
Comparator / control treatment
Eligible registrants from the Australian Stroke Clinical Registry randomised to the control group will continue to receive follow-up as per the standard registry process. That is, at approximately 90 days following admission, a follow-up questionnaire is sent in the mail. If no response is received six weeks later, a second follow-up questionnaire is sent in the mail to the registrant and/or their proxy. If no response is received after another six weeks, the registrant and their listed emergency contact and alternative contact are phoned up to three times to ask if they would like to complete the questionnaire over the phone.

Eligibility
Key inclusion criteria
All registrants known to be alive with an acute admission entered into the AuSCR for either stroke or TIA at a participating hospital with Human Research Ethics Committee approval to implement the SMS message as part of follow-up data collection. Registrants from metropolitan and regional hospitals in Victoria, Queensland, New South Wales, the Australian Capital Territory and Tasmania will be included.

For the process evaluation semi-structured interviews, only those registrants who have completed follow-up, were randomised to the SMS group and indicated they are interested in participation in future research will be contacted.

Key exclusion criteria
Registrants with demographic data entered by hospitals into the registry >180 days post-admission.
Registrants known to be deceased, or have requested no follow-up, or opted out of the registry.
Registrants without a valid mobile phone number.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment will occur using central randomisation by computer with a RedCAP database randomisation module.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A 1:1 block randomisation with minimum block sizes of 6 will be used. We will ensure balanced randomisation between males and females and age groups < 65 years and 65 years or over.
Masking / blinding

Efficacy
Statistical methods / analysis
The sample size for this study is pragmatic and based upon our ability to complete registrant randomisation and the follow-up protocol within a six to twelve-month time frame using existing resources. We estimate we should be able to contact a minimum of 750 and a maximum of 1000 eligible AuSCR registrants for randomisation and follow-up within this timeframe. This would mean that we are able to detect at least a 7% difference between groups (based on the primary outcome) at a confidence level of 95% and a power of 80%.

For the primary analysis, data between the control and SMS/intervention group will be compared, with an intention to treat analysis.

Descriptive statistics will be used to describe the trial population at baseline and to examine within group and between group differences using methods appropriate for the distribution of the data. Where feasible, multivariable statistical models will be used with the outcome measures as the dependent variable, intervention groups as the independent variable and the baseline characteristics will serve as the covariates.

Descriptive statistics of the cohort choosing to complete follow-up electronically via SMS will be completed including both demographic (gender, age, state of residence, living arrangements), clinical characteristics (stroke type, stroke severity) and post-stroke outcomes (subsequent strokes/hospital readmissions, level of disability and health related quality of life). We will use statistical tests appropriate to the type and distribution of the variables.

Qualitative analysis
All interviews will be recorded, transcribed verbatim and participant-identifying information redacted prior to beginning the analysis.
Broad coding of themes and subthemes from review of the identified concepts in the transcribed text will be done and a coding tree developed. At least 10% of interviews will be dual-coded by a second researcher. Discrepancies in assignment of codes will be resolved and the coding tree adjusted if required, prior to completing all coding of transcripts. Systematic coding of the themes and subthemes will be undertaken moving from broader to narrower themes/sub-themes looking for similarities. Should new themes emerge, it will be compared with already identified codes in order to incorporate it into an existing theme or a new theme will be created.
