Value sets and the problem of redundancy in value set repositories.

Objective: Crafting high-quality value sets is time-consuming and requires a range of clinical, terminological, and informatics expertise. Despite widespread agreement on the importance of reusing value sets, value set repositories suffer from clutter and redundancy, greatly complicating efforts at reuse. When users encounter multiple value sets with the same name or ostensibly representing the same clinical condition, it can be difficult to choose amongst them or determine if any differences among them are due to error or intentional decision.

Value Set Hub: Software for developing and curating high-quality value sets.

Terminology value sets are central to research studies using real-world patient data. We describe the considerable challenges that arise when researchers develop value sets for their studies or reuse those made by others. We present Value Set Hub (VS-Hub), software to overcome these challenges, describing its design, implementation, features, use in the field, lessons learned, and future directions.

Cybersecurity Advocates: Discovering the Characteristics and Skills of an Emergent Role.

Purpose: Cybersecurity advocates safeguard their organizations by promoting security best practices. However, little is known about what constitutes successful advocacy.

Methodology: We conducted 28 in-depth interviews of cybersecurity advocates.

Tensions of network security and collaborative work practice: understanding a single sign-on deployment in a regional hospital.

Background: Healthcare providers and their IT staff, working in an effort to balance appropriate accessibility with stricter security mandates, are considering the use of a single network sign-on approach for authentication and password management. Single sign-on (SSO) promises to improve usability of authentication for multiple-system users, increase compliance, and help curb system maintenance costs. However, complexities are introduced when SSO is placed within a collaborative environment.
