Electronic personal health records (PHRs) have the potential to both make health information more accessible to patients and function as a decision-support system for patients managing chronic conditions. Age-related changes in cognition may make traditional strategies of integrating and understanding existing (i.e., paper-based) health information more difficult for older adults. The centralized and integrated nature of health information, as well as the long-term tracking capabilities present in many PHRs, may be especially beneficial for older patients’ management of health. However, older adults tend to be late adopters of technology and may be hesitant to adopt a PHR if the benefits are not made clear (perceived usefulness). Toward the design of a useful PHR, a needs analysis was conducted to determine how people currently manage their health information, what they perceive as useful, and to identify any unmet needs. This paper describes two qualitative studies examining the health information needs of both younger and older adults. The first study used a 2-week diary methodology to examine everyday health questions or concerns, while the second study examined maintenance of health information and perceptions of PHRs through the use of a three-part interview. User’s perceptions of the usefulness of PHRs are provided as recommendations for the design of e-health technology, especially those targeted for older adult healthcare consumers. The results suggest that both older and younger adults would deem a PHR useful if it provides memory support in the form of reminders, provides tools to aid in comprehension of one’s health concerns, is interactive and provides automatic functions, and is highly accessible to authorized users, yet one’s information is kept secure and private.
