Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The "Cardiac/Diabetes TRANS-CARE program", which consists of two face-to-face sessions, a home visit and telephone follow-up. Purpose of the intervention: to increase self-efficacy to enhance self-management behaviours and thus improve health outcomes and reduce hospital readmissions.

Contents/Duration (Reference: Wu & Chang 2014 http://onlinelibrary.wiley.com/doi/10.1111/inr.12104/pdf ):
- 2 sessions (2 x 30 minute sessions, separated by 1 day) while in hospital: these sessions will be provided by a trained research nurse, and focusing on 1) assessing patient’s knowledge of their conditions and skills and confidence in self-management; 2) providing patient examples or models of someone in a similar situation.
- 1 in-home visit with duration of approx 1 hour: The home visit will be provided by a trained research nurse within the first week post discharge. This visit is to ensure that patients will be sufficient support, information, self-management activities including their treatment regimens are carried out in home environment, reinforcement and further explanation of self-management program
- weekly telephone calls for 4 weeks after home visit, and monthly up to 6 months. These calls will be undertaken by the trained research nurse. The telephone follow up calls are to ensure that patients have sufficient support, to encourage and reinforce the participant to continue practising the knowledge and skills to self-manage their conditions. Each phone call will take 20-30 minutes.

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)
Baseline data collection is blinded and will be undertaken before randomisation. Allocation will be concealed by using sealed, numbered, opaque envelopes; list generation will be provided by researcher off site, after randomisation. Patients are not blinded to ‘intervention’ and surveys do not have group ID, thus data entry is blinded.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table (computerised sequence generation) will be used.
Masking / blinding

Efficacy
Statistical methods / analysis
An initial target of 432 eligible subjects will be recruited to the study. It is anticipated that there will be approximately 20% attrition over the 6 month follow-up period, to enable >90% power to detect a difference between groups in 6-month readmission rate. To inform the effect size for this sample size calculation we performed a subgroup analyses from our previous randomised trial that investigated an intervention with a home visit and 6-month telephone follow-up. That sub-group analysis (n=49) indicated a between group difference in 6-month readmission rate of 31.5% (Medium effect size), with statistical significance level of .05.
1) Baseline data for both the intervention and control groups will be examined to check for similarity of the groups.
2) Comparisons between groups will be undertaken. e.g. Chi square tests will be used for proportions of patients re-admitted.
3) Repeated measures regression model will be used to investigate differences over the 4 data collection points and determine the effect of the intervention over time.
4) The economic evaluation will comprise a cost-effectiveness (cost-utility) modelling conducted alongside the RCT

Because the sample size estimate for this investigation was not calculated from pilot data obtained from this specific target population, an interim analysis of hospital re-presentation event rate in the sample will be undertaken. This analysis will examine the 3-month representation rate (both groups combined) to see whether it is higher or lower than rates used in the sample size calculation. This will be conducted using the first (approximately) 10% of the target sample to reached the 3-month re-assessment point by a statistician not involved in the day-to-day operations of the trial. The statistician will be provided with a dataset from each trial site that does not include a variable for group allocation and no attempt to compare event rates between groups during the interim analysis will occur. Rather the sole purpose of the event rate interim analysis is to verify or refute whether the effect size used in the initial sample size estimate is plausible based on the rate at which patients in the target sample are re-presenting to the participating hospitals. If the event rate is substantially discordant with the sample size estimate the investigator team will decide (in conjunction with the local ethics committees) whether an amendment to the trial protocol (to increase the sample size or cease the trial early) is warranted.
