BACKGROUND
Heart failure exacerbations consume 60-70% of costs for the condition and COPD exacerbations lead to 1:8 admissions so are costly to the NHS. The roll-out of telemonitoring in chronic disease is in line with NHS policy (Building Telecare in England; High Quality Care for All, national health service (NHS) next stage Darzi review).
Despite systematic reviews, the Whole System Demonstrator programme and randomised control trial (RCT) evidence in heart failure, the outcome of implementing telemonitoring is unclear, the evidence base in COPD is less consistent, and few studies have included economic analysis or investigated cross speciality implementation. An Italian trial found that telemedicine reduces chronic respiratory admissions by a third, but the Italian health service differs from the united kingdom (UK) system. The european union (EU) Commission Communication on telemedicine 2009 has stressed the need for new deployments to contribute to the evidence base in respiratory disease, and include a detailed analysis of the process changes that determine success. Our group has previously shown that telemonitoring reduces unplanned admissions in heart failure patients, and that elderly patients were able to cope well with the equipment. The investigators have also had experience with telesupport in chronic respiratory patients.
RATIONALE FOR CURRENT STUDY
The study will assess the implementation of a telemonitoring programme to demonstrate
- whether home telemonitoring alerts patients and health professionals to exacerbations and reduces admissions,
- if it can be reasonably implemented cross specialty,
- the impact on quality of life of patients,
- interaction between healthcare professionals, robustness of algorithms and self efficacy in patients.
The cross-over design allows sustained effects on self care and admissions to be assessed after removal of telemonitoring at 6 months in first groups treated. The acceptability of telemonitoring to healthcare workers and factors aiding and limiting integration into care pathways will be explored. Results should inform the commissioning of telemonitoring locally/nationally, facilitate buy-in from secondary and primary care teams, and optimise cost.
OVERALL DESIGN
Design: Crossover implementation study with patients allocated randomly 1:1 to telemonitoring or delayed entry to telemonitoring (after 6 months). All patients with receive standard optimal medical care according to European Society of Cardiology (ESC) Heart Failure guidelines, National Institute for Health and Care Excellence (NICE) COPD guidelines or other best practice care pathways as relevant to their condition. Each patient will receive home telemonitoring for 6 months. Comparisons will be carried out between patients with delayed entry (controls) and active telemonitoring. In the group receiving telemonitoring in first 6 month period the investigators will be able to assess impact of withdrawal in subsequent 6 months ie longer term benefit.
TELEMONITORING
Data from the monitors are delivered to the health care team members personal computer (PCs) using a dedicated broad band line which is installed in the patients home and is routed via a secure Philips Server. Each patient receives education in using the device until he or she and/or family/carer are fully confident. Via information displayed on their television screen each day patients are requested to answer interactive questions on level of breathlessness, sleep quality, phlegm production, wheeze. These results from each patient is used to create a warning system such that if all parameters are satisfactory this will appear as a green light; or for example, if a drop in arterial oxygen saturation and increase in wheeze, or increase in weight and increased breathlessness is seen the Motiva system will generate a red light for that patient which needs to be acted upon. It is an interactive system and therefore the healthcare team member can advise the patient through their screen (eg. increase dose of diuretic or oxygen flow rate, start antibiotic and steroids), or provide educational material eg. on inhaler use or exercise, and patients can respond. Patients will also be asked several questions once a week on whether they have consulted their general practitioner (GP), visited an Accident and Emergency Dept or been admitted to hospital.
