The aim of the study is to evaluate whether providing a targeted heart health education campaign to regions at high risk of heart attacks will improve ACS patient's symptom recognition and response.
The intervention will be will be evaluated according to a cluster randomized, stepped wedged design. The clusters are eight local government areas (LGAs) in Victoria, Australia. The main primary outcome will be assessed in consecutive patients presenting to emergency departments from the six LGAs throughout the study period with an ED diagnoses of acute coronary syndrome.
Primary objectives:
To determine if targeted heart health education will:
Secondary objectives
Intervention: To meet the objectives of the study, we will employ HM coordinators for each of the eight high-risk LGAs to organise and deliver our HM education program using HM materials and Partner resources.
Design: The stepped-wedge design is a uni-directional cross-over design - where the randomisation element is when the cluster crosses-over to the intervention following a control period.
Over the 16-month study period, the eight LGAs will move into the intervention phase at two month intervals. As four LGAs are in close proximity, these LGAs will switch from control to intervention periods at the same time to avoid possible contamination.
