Summary
Telehealth systems improve access to cardiac care in remote Ontario. This technology offers effective consultations, boosts patient satisfaction, and reduces healthcare costs for rural residents.
Area of Science:
- Cardiology
- Health Informatics
- Telecommunications
Background:
- Access to specialized cardiac consultations is limited in remote areas of Ontario.
- The University of Ottawa Heart Institute initiated the HEARRT (Healthcare and Education Access for Remote Residents by Telecommunications) program to address this gap.
- The program leverages telehealth to connect remote patients with off-site cardiology services.
Purpose of the Study:
- To evaluate the effectiveness of a telehealth system for improving access to cardiac consultations in remote Ontario.
- To assess patient satisfaction and cost-effectiveness of the implemented telehealth program.
- To determine optimal telecommunications bandwidths and encoding systems for remote cardiology assessments.
Main Methods:
- Utilized video, electronic stethoscopes, document cameras, and VCRs for remote patient assessments.
- Transmitted laboratory results and echocardiograms digitally.
- Evaluated various telecommunications bandwidths (384 kbps to 40 Mbps) and encoding systems.
- Assessed patient satisfaction through surveys and analyzed cost-effectiveness.
Main Results:
- Bandwidths of 4-6 Mbps are necessary for detailed cardiac physical examinations via telehealth.
- A preliminary patient satisfaction survey showed all participants felt effective communication and confidence in advice received.
- Telehealth is projected to reduce overall healthcare spending and patient travel expenses.
Conclusions:
- Telehealth technology is advanced enough for effective off-site cardiology assessments.
- A strong business case exists for implementing telehealth to serve remote populations in Northern Ontario.
- Future plans include developing a commercialization strategy for broader adoption across Ontario, including patient and medical education.

01:26Methods Of Healthcare Delivery System
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...

01:30Primary Healthcare Services
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

01:21Tertiary Healthcare System
Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care to...
01:20Integrated Healthcare System
An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...
