Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is in the form of a robot that reminds people to take medication and do exercises, and measures spirometry, weight, pulse oxygen, self-reported health, and feeds this information to a health professional monitoring this data who responds if necessary to prevent exacerbations. The duration of the intervention is 4 months. The robot sits in the home of the patient - it is not carried around. The frequency of the medication reminders depends on the individual patient but for most patients will be twice daily. The other measures will be daily for the first 3 days and weekly after that. Data from the robot goes to a secure server that can be accessed by the healthcare team. The activity monitors are worn on the wrist to measure exercise. This information is also linked with the robot and the secure server so the healthcare team can monitor adherence to exercise regimes. The smart inhaler data can also be viewed on a secure server by the healthcare team to monitor inhaler use and adherence. In addition, adherence is measured as self-reports both on the robot and by questionnaire at the start and end of the study. The smartphone provides a link between the robot, smartinhaler and the server and allows contact between the patient and the healthcare team.

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)
Potential patients will be identified at hospital discharge and outpatient clinics at Counties Manukau, Gore Health and Southland DHBs. Eligible patients will be invited to take part in the trial and written informed consent will be obtained. They will be unaware to which group the subject will be allocated to. Allocation will involve contacting the holder of the allocation schedule who will be off site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
60 participants will be block randomised (by site, Gore/Southland or Middlemore) after completion of baseline data collection to either the robot or the control group, by a distant researcher not connected to recruitment. We will use stratified randomisation to match groups for ethnicity and gender.

Efficacy
Statistical methods / analysis
Analysis will be performed by a researcher blinded to group allocation. Survival analysis will test the impact of the strategies on time to hospitalisation. Regression models (taking into account repeated measures) will be used to compare groups on functioning, adherence, mental state and loneliness, and baseline measurements will be taken into account. The difference in days of hospitalisation, and length of stay will be compared between groups. We will perform subgroup analysis based on ethnicity and control for socio- economic status and number of comorbidities (CCF, PH IHD, CVA, Diabetes). Analysis will be carried out using SPSS and SAS.
We aim to conduct a study based on a sample size that will provide useful indications of cost- and clinical effectiveness. A NZ trial showed that case management for 16 patients with at least 4 admissions over the previous 2 years for COPD, reduced number of admissions and length of stay compared to control patients 15. Median length of stay was 5.8 days for the control group and 3.5 days for the intervention group. Using a standard deviation of 2 days, this is an effect size of 1.15. It is hypothesised that telehealth will have a similar effect on hospitalization days. The required sample size is 16 patients per group (intervention/control) with a significance of .05 and power of .90. To allow for a subgroup analysis by ethinic group will aim to recruit 60 patients in total.

Summary
Brief summary
The objective is to investigate whether new technologies can reduce days of hospitalisation for high-risk patients with COPD. A randomised controlled trial will be conducted with Counties Manukau DHB, Southland DHB and Gore Health. Sixty participants will be randomised to receive either standard care, or standard care plus a robot. The robot will be programmed to provide medication management, telemedicine, spirometer readings and blood oxygen monitoring, monitoring of activity using wearable activity sensors, COPD questionnaires, and be linked to Smart inhaler devices to monitor adherence. The data from the robot and smart inhalers will be monitored and if the early signs of an exacerbation are detected, appropriate treatment will be provided to patients. The hypotheses are that telehealthcare (the robot) will reduce hospital admissions and bed-care days compared to a control group, as well as improvements in mental health, loneliness, and adherence. This research will deliver information about the clinical- and cost-effectiveness of these technologies to inform COPD care.
