    Introduction Unpaid informal caregivers of adult care recipients, including persons with dementia, experience multiple unmet information needs and information management challenges. Objectives To understand the current personal health information management (PHIM) practices in informal caregiving for adults with and without dementia. Methods Semi-structured interviews were performed with ten informal caregivers—half of whom were caring for persons with dementia—and four formal caregivers at an adult day service. Interviews centered on a paper-based tool distributed by the day service, the CARE Kit, permitting an artifacts analysis of the tools used by participants for PHIM. Qualitative thematic analysis was applied to interview data. Results Caregivers’ PHIM practices aimed to support daily care management and decision-making on behalf of care recipients, through: 1) information acquisition and integration across multiple sources and records; 2) information maintenance, updating, and use over time; and 3) information sharing and communication with healthcare professionals and other family caregivers. Participants reported advantages and challenges of their PHIM practices and tools, including fitting PHIM into their daily lives, managing PHIM-related cognitive workload, the functionality of PHIM tools, and the dynamic, longitudinal nature of PHIM. Conclusion The study produced a number of implications for caregiver health information management information technology (CHIM IT), based on findings about the nature of caregivers’ practices for managing information for adult care recipients. We present CHIM IT requirements related to privacy and security, customization and flexibility, ease of use, credibility and sensitivity, situation awareness, information integration, delegation and shared use, updating and maintenance, archiving and versioning, communication, agency and information access, and validation.

    Media, Meaning, and Context Loss in Ephemeral Communication Platforms: A Qualitative Investigation of Snapchat
    (ACM, 2017-02) Cavalcanti, Luiz Henrique; Pinto, Alita; Brubaker, Jed; Dombrowski, Lynn; Human-Centered Computing, School of Informatics and Computing
    Most social media platforms are persistent in nature, enabling users to re-visit content at their discretion. Platforms with design features that support ephemeral communications, such as Snapchat, have become increasingly popular. During the course of our empirical study, we interviewed 15 Snapchat users about their experiences and practices. Our data reveal that Snapchat users experienced different types of loss, including media, meaning, and context loss, and developed workarounds to deal with those losses, including preemptive action and collaborative saving practices. Our findings revealed a conflict between the user's expectation of the affordance the ephemeral platforms would provide, and the actions user's followed.
