About this study
Official title: Pragmatic Randomized Controlled Trial of the Cardiovascular Health Awareness Program (CHAP) in Subsidized Social Housing
This project aims to improve the cardiovascular health of seniors living in subsidized housing by implementing the successful community-based Cardiovascular Health Awareness Program (CHAP). CHAP is a patient-centred, interdisciplinary, multi-pronged, community-led CVD and stroke prevention and management program designed to prevent and reduce the impact of cardiovascular disease in older adults. The program addresses common cardiovascular disease risk factors, such as smoking, physical activity and poor diet by raising awareness of health and community resources available to encourage self-care and appropriate management of cardiovascular disease. A randomized controlled trial will be used to evaluate the impact of CHAP on healthcare utilization by older adults living in subsidized housing.
Read the detailed description
This project aims to improve the cardiovascular health of seniors living in subsidized housing by implementing the successful community-based Cardiovascular Health Awareness Program (CHAP). Residents in subsidized housing are considered to be a vulnerable population because of their low income and tend to be in poorer health; with a multitude of chronic illnesses, such as cardiovascular disease (CVD) and diabetes.
This project will build on the success of CHAP in other provinces. The program has been shown to reduce blood pressure and CVD-related hospitalization costs. CHAP is a patient-centred, interdisciplinary, multi-pronged, community-led CVD and stroke prevention and management program designed to prevent and reduce the impact of cardiovascular disease in older adults. The program addresses common cardiovascular disease risk factors, such as smoking, physical activity and poor diet by raising awareness of health and community resources available to encourage self-care and appropriate management of cardiovascular disease.
Taking the form of a randomized controlled trial, the sample will be subsidized housing buildings (low income) for those aged 55 years and over. During CHAP monthly assessment sessions, participants will 1) complete a consent form, 2) complete a cardiovascular risk profile form, 3) undergo blood pressure measurement using an automated blood pressure measuring device, 4) receive targeted healthy lifestyle and preventive care materials, 5) be invited to participate in group health education sessions. Those patients identified at high risk will be assessed by a health professional and referred to a family physician for timely and appropriate follow-up.. The impact this program will have on health care utilization (emergency visits, cardiovascular hospitalization rates) will be measured using administrative databases.

Cardiovascular Health Awareness ProgramBehavioural
Cardiovascular disease prevention and health promotion
| Study group | Role | What they receive |
|---|---|---|
| CHAP Intervention | Experimental | The Cardiovascular Health Awareness Program (CHAP) intervention is an on-site drop-in, monthly, cardiovascular risk assessment program run by trained volunteers with community-led group health sessions that deliver education and information about access to community health resources. The education sessions will be delivered by national and provincial and local community organizations utilizing already developed material as much as possible, but maintaining consistency across both provinces. Health education sessions will include topics such as: Physical Activity, Healthy Eating, Stress, Tobacco Use, High Blood Pressure, Role of Pharmacist: How they can assist people, and Appropriate use of 9-1-1. This intervention will be held in a common room in selected subsidized housing buildings. Receives: Behavioral: Cardiovascular Health Awareness Program |
| Control | No intervention | The control buildings will receive usual care which will be wellness programs already present in the building prior to the RCT if these are present. Not all control buildings will have wellness programs. |

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Healthcare Utilization Composite - Change in CVD-related emergency department visits and hospitalizations (time frame: Monthly from 1 year pre-intervention to 1 year post-intervention). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03549845, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2023; AzTrials last refreshed its copy on 7 Nov 2026.
