Plain English Summary

Background and study aims
A cardiac rehabilitation program (CRP) helps you get back to as full a life as possible after a cardiac event such as a heart attack, heart surgery or stent procedure.
In Spain, only 3% of heart disease patients carry out a CRP. Among the reasons, the shortage of healthcare resources and inflexible ways of providing CRPs. In this context, online-based healthcare services (e-services), can act as an effective element of coordination and support new models of healthcare provision.
The study aims to investigate the usefulness of a CRP carried out online, compared to the usual in-person CRP.

Who can participate?
Patients aged 18 - 75 years, requiring phase II cardiac rehabilitation.

What does the study involve?
Participants will be randomly allocated to receive either 8 weeks of online CRP or in -person CRP. Participants will perform some tests and answer some questionnaires before the start of the CRP and at a 16 month follow up.

What are the possible benefits and risks of participating?
There are no additional benefits or risks to participating, although some patients may have symptoms of anxiety and concern about the control of their disease.

Where is the study run from?
University Hospital Ramon y Cajal (Spain)

When is the study starting and how long is it expected to run for?
May 2014 to June 2019

Who is funding the study?
Instituto de Salud Carlos III (Carlos III Health Institute) (Spain)

Scientific title

Implementation and evaluation of a telemedicine-based service to support "e-supervised" regime in Phase II Cardiac Rehabilitation Programs: a randomised controlled trial



Study hypothesis

1. The implementation of e-services through virtual environments that combine aspects of biomedical and contextual monitoring programs with "e-learning" programs, social, educational and interactively structured, can develop models of provision of cardiac rehabilitation programs (PRC) more flexible, personalized, with ubiquitous nature and security for all parties involved
2. The provision by means of this type of e-services of selected therapeutic components from the PRC in phase II cardiac rehabilitation (physical activity, psychological therapy and control of risk factors) is feasible, reaching at least similar results to those of the traditional provided means "supervised regime" in both clinical indicators and those of satisfaction and quality of life
3. The PRC Phase II provided through these e-services can increase patient involvement in self-management of their health during phase III cardiac rehabilitation, stating medium term at least similar clinical indicators, satisfaction, quality of life and adhesion, regarding patients who followed supervised traditional regime phase II
4. The provision of PRC through this kind of e-services enables increasing the population of patients who can benefit from this therapeutic care process

Cardiac rehabilitation


Both groups follow a phase II cardiac rehabilitation program, they are monitored for 8 weeks
Intervention group supervision is by the telemedicine system
Control group have on-site supervision in the rehabilitation unit

After that, both groups continue unattended rehabilitation for 12 months (first year of phase III of cardiac rehabilitation). At the end of the first eight weeks, an intermediate visit is carried out in order to analyze the effectiveness during phase II (main and secondary outcomes). At the end of the last 12 months all of them have a final visit for data collection (secondary outcomes).

Randomisation process
To support the randomisation process, a table of pseudo-random numbers in variable and permuted blocks was generated by computer for random assignment: intervention and control. Through a private secure web service, the values of the randomisation table are delivered in a strictly sequential way. The access to the randomisation web service is done automatically from the Electronic Case Report Form software. Once the patient has given informed consent, random assignment to the intervention or control group takes place on-line, automatically, as the initial step in creating the patient's electronic case report form. There is no possibility of interfering with the randomisation process.

Telemedicine system and onsite supervision
Phase II programs are the central pillar of cardiac rehabilitation. During phase II, systematic rehabilitation activities are carried out, limited in time (around eight weeks), in multiple areas: physical (resistance and strength); psychological (anxiety control, relaxation); education in cardiovascular risk factor control (medication, life habits); return to work; sexual dysfunction; among others. The activities are programmed in relation to their scope and intensity, according to the patient's conditions and a stratification of cardiovascular risk (usually low, medium and high risk) and the units' own capacities and resources.
The objective of this action has been to implement and evaluate a low-risk phase II cardiac rehabilitation program (called “e-supervised”), with high personalization capabilities, aimed at the daily life environment of the patient-citizen, using information and communication technologies. The “e-supervised” program has been evaluated by means of a randomized controlled clinical trial to demonstrate no inferiority in the results of the efficacy of an eight weeks phase II intervention, compared to a traditional “supervised” program carried out in person at the Cardiac Rehabilitation Unit.
Traditional onsite phase II cardiac rehabilitation is carried out “face-to-face” (patient and multidisciplinary teams) and with close supervision of the patient in cardiac rehabilitation units. This “supervised” phase II programs incorporate above mentioned therapeutic activities (physical, psychological, education), very systematic but with an inflexible schedule for the patient and limited capacity-availability.
The "e-supervised" program incorporates the following components (supported by a telemedicine platform): resistance physical rehabilitation components (walking sessions); psychological rehabilitation components (relaxation sessions in 5 modalities); multimedia educational program (12 educational environments and 70 resources); web messaging with guaranteed response in less than 24h (from both, the healthcare and the technical support teams); video call; and discussion forums. The program is personalized through the specification of a 4-dimensional patient profile (diagnostic profile, risk factors, psychological, others) and 26 distributed characteristics from which the program components are automatically selected (from the working heart rates in walking sessions, to the videos that have to do with the educational program and its sequencing). Both patients and professionals have the possibility of carrying out the follow-ups and interactions through a web platform. Walking and relaxation activities are performed through apps with real-time heart rate monitoring (smartphones and heart rate monitoring wearable devices); apps incorporate algorithms that, based on the heart rate, geolocation information and profile data, make it possible to parameterize and control the sessions and automatically guide the patient during the activities (walking and relaxation) through audio messages. Through this virtual assistant service, the therapeutic result of the activity and the objective and subjective security perceived by the patient (and by the health professional) are optimized.
The "e-supervised" program has been designed to be consistent and complementary to traditional "supervised" programs. It is also a highly customizable program in relation to its components, duration and activity scheduling; the timing of activities is adjusted to patient preferences rather than to necessary on-site assistance. The monitoring, computing and interaction capabilities that technology makes possible to objectify not only the result but also the development of the activities, so that it is possible to control and guide the patient through automatic virtual assistants, improving therapeutic effects and perception of security. In relation to the interaction channels, it offers patients and professionals with a flexible messaging system with the capacity to distribute messages among the multidisciplinary healthcare team and with a guarantee of an agreed response in short periods of time, in order to improve the perception of safety and adherence of the patient to the therapeutic and education activities. Additionally, the possibility of offering to low-risk patients to carry out phase II programs outside the cardiac rehabilitation units with no inferior results, makes it possible to decongest the units and redirect them to the treatment of medium and low-risk groups, rationalizing and increasing the benefit of the care resources. In addition, the ubiquity of the program's provision allows citizens who do not have any access to specialized units to benefit from cardiac rehabilitation.
