Effects of Telemonitoring on the Outcome of Heart Failure Patients After an Incidence of Acute Decompensation (Medly-AID)

May 27, 2026 updated by: University Health Network, Toronto

Effect of a Mobile Phone-based Telemonitoring Program on the Outcome of Heart Failure Patients After an Incidence of Acute Decompensation

Heart failure is the most rapidly rising cardiovascular disease and has come to be recognized as a growing epidemic. Digital health interventions are the most recent iteration of an effort to promote individualized outpatient care through positive behaviour change theory. The UHN team has developed a highly automated and user-centered smartphone-based system, Medly, which allows for the telemonitoring of patients diagnosed with heart failure. The purpose of this study will be two-fold: 1) to determine if the introduction of Medly within two weeks of discharge will improve self-care management, quality of life, and clinical status, 2) to assess whether Medly will lead to a potential reduction in 30 day readmission rates amongst HF patients in the Toronto Central Local Health Integration Network (TC LHIN), without increasing the average length of stay or visits to the emergency department. These parameters will be measured as secondary outcomes.

Detailed Description

Heart failure is the most rapidly rising cardiovascular disease and has come to be recognized as a growing epidemic. Digital health interventions are the most recent iteration of an effort to promote individualized outpatient care through positive behaviour change theory. The UHN team has developed a highly automated and user-centered smartphone-based system, Medly, which allows for the telemonitoring of patients diagnosed with heart failure

Patients with heart failure will be provided with a smartphone and commercial home medical devices, such as a blood pressure monitor and weight scale. The measurements from the medical devices will be automatically sent to the smartphone, and from there to a data server at the hospital for analysis and storage. Both clinicians and patients will be able to access these data and will be sent alerts by the system if the measurements are outside of the normal range. The system will be evaluated through interviews and comparing outcomes between the intervention and control groups.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Telemonitoring (Medly)
Medly is a smartphone application allows heart failure (HF) patients to measure and record their daily weight, blood pressure (BP), heart rate, and self-reported symptoms. This monitoring information is then transmitted wirelessly to a data server where an algorithm is used to generate an alert to a healthcare provider as necessary. The patient also receives an automated self-care message based on their measurements and reported symptoms.
Medly will enable patients with HF to take clinically relevant physiological measurements with wireless home medical devices and to answer symptom questions on the smartphone. The measurements will be automatically and wirelessly transmitted to the mobile phone and then to a data server. Automated self-care instructions/messages 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. 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.
No Intervention: Control
Standard of care: Control groups will receive standard medical care when discharged from hospital, including discharge instructions, home medications as well as follow-up in a heart failure clinic or with a primary care doctor.
