Plain English Summary

Background and study aims
Remote patient monitoring can be used to manage chronic (long-term) conditions by providing measurements to support clinical decisions, alert clinicians when there are problems, and help patient to manage their condition. The aim of this study is to test a remote monitoring system called Medly for patients with complex chronic conditions such as heart failure, COPD, chronic kidney disease, and uncontrolled hypertension. Heart failure is a condition where the heart is unable to pump blood around the body properly. Chronic obstructive pulmonary disease (COPD) is a collection of lung diseases that cause breathing difficulties. Chronic kidney disease is a condition where the kidneys do not work effectively. Uncontrolled hypertension (high blood pressure) increases the risk of heart attacks and strokes.

Who can participate?
Patients aged 18 or over with heart failure, COPD, chronic kidney disease, and/or uncontrolled hypertension

What does the study involve?
Participants are randomly allocated into two groups: control or telemonitoring. The control group receive the current standard of care. Participants in the telemonitoring group are provided with a mobile phone and commercial home medical devices, such as a blood pressure monitor and weight scale. The measurements from the medical devices are automatically sent to the mobile phone, and from there to a data server at the hospital for analysis and storage. Both clinicians and participants are able to access these data, and are sent alerts by the system if the measurements are outside of the normal range. The system is tested through interviews and comparing outcomes (e.g., health, cost of healthcare) between the intervention and control groups over 6 months.

What are the possible benefits and risks of participating?
By participating in this study, patients have the opportunity to experience using a new application that is not yet available on the market and is part of a new approach to improving chronic illness management. The application may or may not improve their health. There are no medical risks to the patients from participating in this study. They may experience slight discomfort with sharing their opinion with the study coordinator. However, they are free to withdraw from the study at any time, and their participation in this study has no effect on the level of care provided to them.

Where is the study run from?

Study information

Scientific title

Randomized controlled trial of a mobile phone-based telemonitoring application for self-management and clinical decision support for patients with complex chronic conditions


Study hypothesis

The objective of the randomized controlled trial (RCT) is to evaluate a mobile phone-based telemonitoring system for management of a variety of chronic conditions, including heart failure, complex obstructive pulmonary disease, chronic kidney disease and uncontrolled hypertension in specialty clinic settings. The central research question is: What is the impact of a telemonitoring system for patients with complex chronic illnesses on health status, cost, self-management, clinical management, health outcomes, and health service utilization?

Patient information sheet

No participant information sheet available


Heart failure (HF), chronic obstructive pulmonary disease (COPD), chronic kidney disease (CKD), uncontrolled hypertension, diabetes


Patients will be randomized 1:1 into control and telemonitoring groups (73 in each group). The participants will be block randomized (blocks of 4) and stratified into groups according to their primary condition (HF, COPD, hypertension, and CKD). The HF group will further be stratified based on NYHA classification (NYHA class 2-3, NYHA class 4), and the hypertensive patients will be stratified to those with and those without diabetes.

To perform the randomization, the online computer generated randomization tool, Research Randomizer, will be used ( The study coordinator performing the recruitment will be blinded until the patient has consented to participate.

The telemonitoring technology will enable patients with complex chronic illnesses, including multiple chronic conditions, to take clinically relevant physiological measurements with wireless home medical devices and to answer symptom questions on the mobile phone. The measurements will be automatically and wirelessly transmitted to the mobile phone and then to a data server. Specifically, patients with HF will monitor daily weight and blood pressure/heart rate, CKD patients will monitor blood pressure, and HF, COPD, and CKD patients will monitor symptoms. Hypertension patients will monitor their blood pressure. Automated self-care instructions/messages that have been carefully developed with healthcare specialists will be sent to the patient based on the readings and reported symptoms. If there are signs of their status deteriorating, an alert will be sent to a clinician that is responsible for the particular chronic condition of concern (i.e., in the specific specialty clinic). The clinicians will have all the relevant patient data sent to them and will be able to access (through a secure web portal) to view historical and trending data for their patients. Additional app features will also be available, such as educational videos for proper inhaler use for COPD patients.

The control will not receive any interventions. They will receive current standard of care.

Intervention type



Drug names

Primary outcome measures

1. Health status: The SF-36 questionnaire will be administered at baseline, 1 month and 6 months
2. Cost of healthcare assessed at 6 months: The cost of the intervention will be tracked, including for equipment costs and human resources for clinical support, technical support, and program management. Standard cost values for a day in-hospital, ED visit, etc. will be used to estimate net cost savings or expenditures

Secondary outcome measures

All the following data (unless otherwise stated) will be collected through patient self-administered questionnaire and through the hospital EMR and a manual chart review of all participants’ clinical records. Timepoints for data collection are in parentheses.

All participants:
1. Combined hospitalization: Number of hospitalizations, days in hospital, number of ED and clinic visits, and medications will be determined through the hospital EMR and a manual chart review of all participants’ clinical records (baseline, 1 month, 6 months)
2. General quality of life: EQ-5D questionnaire (baseline, 6 months)
3. Mortality: assessed at 6 months

Condition-specific outcomes:

Heart failure:

3. Self-care: Self-Care of Heart Failure Index (baseline, 1 month, 6 months)
4. Heart-failure specific quality of life as measured: Minnesota Living with Heart Failure Questionnaire (baseline, 1 month, 6 months)

6. Blood work: creatinine, sodium, potassium, hemoglobin, urate (baseline, 6 months)
