While revascularization techniques have improved immediate health outcomes among severe coronary artery disease (CAD) patients, successful management of CAD is significantly influenced by patient engagement. This study explores the acceptance of electronic personal health records (ePHRs) and its impact on patient engagement and health outcomes among post-coronary revascularization patients.
200 patients with severe CAD as evidenced by coronary artery bypass graft surgery or percutaneous intervention were provided an interoperable ePHR, pre-populated with information from their electronic medical record at Parkview Physicians Group-Cardiology. Patients received ePHR training followed by a survey, conducted under standard conditions. Surveys and intermediate outcome measures (body mass index, blood pressure, lipid status and Hemoglobin A1c) were gathered at baseline and will be collected at 6 and 12 months. Surveys include estimation of acceptance of the ePHR using the Technology Acceptance Model and the Patient Activation Measure (PAM), a validated survey which assesses the degree to which a patient is an active agent in their health care.
This feasibility study of 200 patients measures the level of patient engagement and acceptance of ePHR technology. Baseline findings indicate a strong association between the level of engagement and intention to use the ePHR (p<0.001). Patients who were considered proficient computer users according to their survey responses had significantly higher PAM scores (P<0.001). Although computer proficient users find the ePHR easier to use, proficiency does not appear to influence perceptions about the usefulness of the ePHR. Intermediate outcome measures were collected at time zero and will be repeated at 6 and 12 months to determine if ePHR use has an impact on intermediate health outcomes.
Preliminary results indicate a strong association between the level of engagement and intention to use the ePHR suggesting that the ePHR appeals to patients who take an active role in their health care. Additionally, patients are interested in using ePHRs to enhance their health regardless of computer skill level.
