Objectives: To examine uptake patterns of the electronic health risk assessment (eHRA) and compare characteristics of early adopters among adults in 1 healthcare system with those of the potentially eligible population.
Study design: Retrospective cohort study (September 2006-March 2009).
Methods: We designed and implemented an integrated eHRA to improve individual health plan members' self-management of their health risks and chronic illness. We included individuals aged 21 to 85 years who had been enrolled at Group Health Cooperative for 12 or more months before September 2006, when the eHRA was first introduced. Study participants had to be registered users of the health plan's secure Web portal by March 2009 in order to complete the eHRA.
Results: A total of 332,381 adults were potentially eligible; of these 39.3% were eligible to complete the eHRA. One or more eHRAs were completed by 22.4% of registered Web portal users over the study period with slow but consistent uptake. Completers were more likely to be women, to be middle-aged (41-65 years), and to have had a recent well-care visit and fewer comorbid conditions.
Conclusions: Significant additional outreach, engagement strategies, and incentives are likely required by health systems to increase adoption and ongoing use of an eHRA among target populations. Future research on eHRA uptake in primary care should focus on whether the use of these tools leads to patient action and provider engagement that improve health outcomes in moderate-risk and high-risk individuals, as well as on modalities to reach broader audiences for higher completion rates.
