A Systems-Based Patient Aid Design Artifact for Active Medication Management in Type 2 Diabetes

<p>In this dissertation, I explore the use of the Abstraction-Decomposition Space (ADS) alongside Hierarchical Task Analysis (HTA) to guide the design of a minimalist patient aid for active medication management in type 2 diabetes. The goal is to address a practical problem, but in addition, this study seeks to address a theoretical problem that is prevalent in design research in Information Systems (IS) today. The practical problem concerns the need for IT-based care delivery models to support patients in the interim period between in-person visits. In this vein, I present a bare-minimum design that focuses on the most essential functionality required to achieve remote insulin titration using the ADS and HTA. The theoretical problem, on the other hand, pertains to the limitations resulting from taking a tool-focused view in design research which inhibits our ability to produce generalized knowledge about IT systems in their contexts. The study proposes an alternative view based on work systems. The overarching thesis is that a work systems view provides for knowledge at a more abstract and generalizable level, yielding contributions beyond mere software packages. Moreover, the study highlights the artifact-building methodology used to delineate the rationale behind the design and to balance evaluation-dominant design research. In this vein, I conducted document analysis and semi-structured interviews with patients and care providers to develop the ADS, then used it alongside HTA to develop and test the usability of twelve user scenarios implemented on a large mobile form factor.</p>
