Plain English Summary
Background and study aims
Chronic obstructive pulmonary disease (COPD) is a common cause of illness and death, with sufferers being extensive users of the healthcare system. Studies have suggested that telemonitoring (Tm) can deliver clinical benefits to patients living with chronic conditions including COPD. However, what has not been clearly established for best clinical benefit is:
1. Which should be the target patient population?
2. Which measurements are most appropriate and useful? (e.g., spirometry, pulse oximetry, temperature, symptom management questions and quality of life questions)
3. The added value of video consultation.
4. The optimal duration for comprehensive Tm on an ongoing basis.
5. How could Tm be better utilised to reflect an individual patient's health status at any given time?
This study aims to address these issues.
Who can participate?
The study aims to recruit 200 patients over the age of 18 who have been discharged from any of the four district general hospitals in the Hywel Dda University Health Board in Wales (Bronglais, Glangwili, Prince Philip and Withybush) following admission for an acute exacerbation (worsening) of COPD (AECOPD). In addition, 200 historical controls who have been admitted following an AECOPD will be recruited from any of the four hospitals.
What does the study involve?
Upon discharge to within 7 days of discharge from hospital or within 7 days of stopping oral steroids or antibiotics in the community, patients are provided with a telemonitoring package that may include video conferencing, together with a thermometer and a pulse oximeter. Each day the patient will answer their symptom management questions, record their temperature and pulse oximetry readings and upload this data according to their agreed management plan before accessing a video or telephone consultation with a healthcare member of staff. The intervention (provided service) represents three levels of intensity telemonitoring with specific duration for each level:
High Level Tm: daily tele-consultation (preferably via video consultation or telephone if not possible), pulse oximetry and daily symptom management questions for 10 working days after discharge.
Moderate Level Tm: daily pulse oximetry and symptom management questions for up to 12 weeks after discharge.
Low Level Tm: optional symptom management questions and behaviour prompts via text messages or website links for up to 12 months after discharge.
Uniquely, patients can be transferred between these levels (both up and down) according to Tm results and clinical discretion. The controls both prospective and historical will not receive any intervention (i.e., Tm), but their medical notes will be used to establish if there has been a reduction in the number of readmissions for COPD exacerbations.
What are the possible benefits and risks of participating?
The aim will be to deliver a more efficient and effective service for patients. It will be emphasised to patients that the Tm is not a replacement for their usual service delivery, rather that is in combination with standard support. Furthermore, all patients will be treated according to the clinical discretion of their primary care doctors, specialist nurses and hospital specialists. There should be no risks in participating, the interventions provided are intended to supplement rather than replace existing clinical supervision.
Where is the study run from?
The study will be run from the Hywel Dda University Health Board in Wales the intervention patients will be recruited from any of the four district general hospitals. The historical controls will be also be recruited from any of the four district general hospitals within the Health Board.
When is the study starting and how long is it expected to run for?
It is anticipated that recruitment will begin in late 2013, with the aim of recruiting all patients over a 12-month period. Recruits to the study will then be followed up for 12 months post recruitment. The study will run until December 2016.

Does flexible home telemonitoring (Tm) after hospital discharges for chronic obstructive pulmonary disease patients reduce hospital re-admission? A clustered, interventional trial
It is hypothesised that the introduction of a short-term intensive telemonitoring (Tm) programme followed by a less intensive 'step-down' approach to Tm for patients discharged from hospital after an acute exacerbation reduces subsequent hospital re-admission.
The null hypothesis is that there will be no difference in admission rates between those receiving Tm and those not receiving Tm.
On 13/02/2015 the following changes were made to the trial record:
1. The scientific title was changed from 'Does home telemonitoring (Tm) follow-up after hospital discharge for chronic obstructive pulmonary disease patients reduce hospital re-admission? A clustered observational trial' to 'Does flexible home telemonitoring (Tm) after hospital discharges for chronic obstructive pulmonary disease patients reduce hospital re-admission? A clustered, interventional trial'

Chronic Obstructive Pulmonary Disease
For the 'intervention' arm, 200 patients will receive the ability to interact with the Chronic Disease Management Team via the Tm devices following discharge from hospital for an acute exacerbation of their COPD. The Tm is composed of three stages - gold, silver and bronze:
1. High Level Tm (gold): daily tele-consultation (preferably via video consultation or telephone if not possible), pulse oximetry and daily (six) symptom management questions for 10 working days after discharge.
2. Moderate Level Tm (silver): daily pulse oximetry and six symptom management questions for up to 12 weeks after discharge.
3. Low Level Tm (bronze): optional six symptom management questions and behaviour prompts via text messages or website links for up to 12 months after discharge.
Uniquely, patients can be transferred between these levels (both up and down) according to Tm results and clinical discretion.
The Chronic Disease Management Team will have the ability, particularly during the high level Tm stage, to suggest how they may alleviate symptoms/manage their condition better, as the patient and the team will be in direct contact daily using the video conference (or telephone if that is not possible for any reason). An alert email/text is sent to the team if any of the following occur:
1. Pulse rate <50 or >120 bpm
2. Oxygen saturations fall by 6% or more from their discharge baseline
3. Two from six questions are out of range ('worse' or 'more than usual') for two consecutive days
The six symptom questions are:
1. How do you feel today? Better, Usual, Worse
2. Is your breathing: Better, Usual, Worse?
3. Is the amount of your sputum: Better, Usual, Worse?
4. Is your sputum colour: Clear/white, Yellow, Dark Green or Brown?
5. Are you using your reliever inhalers/nebuliser or oxygen: less than usual, same as usual, more than usual
6. Are you taking any extra antibiotics or steroids at the moment for a chest infection? Yes, No
The controls both prospective and historical will not receive any 'intervention' i.e. Tm, but their medical notes etc will be used to establish if there has been a reduction in the primary outcome, the number of (re)admissions for COPD exacerbations between the Intervention and Comparator Groups after 1 month. The comparator group will also be used to assess the secondary outcome measures.
Primary outcome measure
Current primary outcome measures as of 13/02/2015:
Number of (re)admissions for COPD exacerbations within 1 month between the intervention and the comparator group (i.e. the historical controls).
Previous primary outcome measures:

Secondary outcome measures
Assessed 12 months after recruitment
1. Number of admissions (any admission during 12 months)
2. Number of bed days (days of hospitalization)
