The focus of this presentation will be sharing experiences of two studies that employed several human computer interaction research methods in the health care domain. These studies highlight the importance of interdisciplinary and collaborative research that strikes a balance between practical applicability and theoretical contributions. The first empirical study examined human computer usability factors affecting the perception of trust of rural consumers. It investigated the effect Human-Computer Interaction (HCI) usability factors on consumers’ perception of trust when using eHealth services, the importance of an individual’s trust propensity and the influence of health problem severity. HCI usability factors were confirmed to be essential elements in conveying trustworthiness of a web-based system and affect consumers’ perception of trust. Dr Fruhling will also present her current NIH-funded research on Optimizing the Electronic Health Record (EHR) for Cardiac Care. Often, the design and implementation of EHRs do not align with the cognitive and workflow processes of physicians within and across specialties and practice settings. A user interface usability evaluation design approach closely simulated the clinical environment to capture provider/patient/EHR interactions. This identified areas for improvements in efficiency, effectiveness and user satisfactions without compromising patient safety, privacy and organizational security. Improving usability is a critical priority.
