Context: The objective of CHOICES (Community Heart Outcomes Improvement and Cholesterol Education Study) is to understand how evidence-informed cholesterol management can prevent cardiovascular disease (CVD) in 14 health regions at higher risk in Ontario, Canada using a suite of educational interventions. An integrated knowledge translation (IKT) approach was used to co-create an educational tool on CVD risk, behaviour modifications for cholesterol management, and cholesterol-lowering medications. In order to further understand the needs of Ontario residents related to CVD prevention, a process evaluation was conducted through engagement with the public. Objective: To evaluate implementation quality including reach, responsiveness and usability of the patient-targeted educational tool for cholesterol management. Study Design: A 10-minute online survey was administered to users of the tool. Population: Adults aged 40-75 years who reside in one of the 14 identified regions in Ontario with higher-than-average CVD risk. The tool and survey were shared broadly in the targeted regions and participants were recruited through social media, stakeholder involvement, and market research organizations. Outcome Measures: Reach was measured by the number of participants who received the tool and completed the survey. The survey measured perceived usability of organization, layout and applicability of the tool (6-items). Responsiveness was measured by the level of receptivity and interest in sharing the tool (4-items). Respondents ranked their level of agreement to each question on a likert scale from 1 (Strongly Disagree) to 7 (Strongly Agree). Results: 230 users of the tool were recruited to participate, of which 104 completed the survey (response rate= 45.2%). Respondents indicated that the tool’s content was clear (M = 6.00, SD = 1.05) and would support them as a patient seeking cholesterol related information (M = 6.00, SD = 0.99). Respondents indicated their high likelihood to recommend the tool to their personal networks (M = 5.37, SD = 1.19) and preference to receive similar information from their family physician (M = 5.92, SD = 1.15). Conclusion: Overall, participant responsiveness and receptivity to the co-created patient educational tool was high. This work enhances understanding of the benefits of co-created patient-targeted interventions to improve cholesterol management and ultimately inform the implementation of similar scalable strategies across Ontario.
