Mind the gulfs: An analysis of medication-related cognitive artifacts used by older adults with heart failure

Medication management is a patient health-related activity characterized by poor performance in older adults with chronic disease. Interventions focus on educating and motivating the patient with limited long-term effects. Cognitive artifacts facilitate cognitive tasks by making them easier, faster, and more effective and can potentially improve medication management performance. This study examined how older adult patients with heart failure use cognitive artifacts and how representational structure and physical properties facilitated or impeded medication-related tasks and processes. Interview, observation, medical record, and photographic data of and about older patients with heart failure (N = 30) and their informal caregivers (N=14) were content analyzed for cross-cutting themes about patient goals, representations, and actions. Results illustrated patient artifacts designed from a clinical rather than patient perspective, disparate internal and external representations threatening safety, and incomplete information exchange between patients and clinicians. Implications for design were the need for bridging artifacts, automatic information transfer, and cognitive artifacts designed from the perspective of the patient.
