BACKGROUND: Virtual reality (VR) use as a platform for vestibular rehabilitation is widespread. However, the utility of VR based vestibular assessments remains unknown. OBJECTIVE: To compare dynamic visual acuity (DVA) scores, perceived balance, and perceived dizziness when using traditional versus VR environments for DVA testing among healthy individuals. METHODS: DVA testing occurred for both a traditional clinical protocol and in a VR variant. Horizontal, vertical, and no head motion conditions were conducted for both clinical and VR test protocols. DVA scores, balance ratings, and dizziness ratings were obtained per condition. Two-way ANOVAs with repeated measures were used to assess differences in DVA scores, balance, and dizziness ratings. RESULTS: No differences in DVA results, balance or dizziness ratings were observed when comparing traditional clinical protocol versus the VR variant. Differences across head motion conditions were observed, with no motion trials exhibiting significantly higher DVA scores and perceived balance, and lower perceived dizziness compared to vertical and horizontal head motion. Vertical head motion exhibited this same trend compared to horizontal. CONCLUSION: DVA testing conducted in VR demonstrated clinical utility for each measure. Effects of head motion were similar across test variants, indicating DVA testing in VR produces similar effects on vestibular function than traditional clinical testing. Additional research should be conducted to assess the feasibility of VR assessment in individuals with vestibular disorder.

The rapid growth and acceptance of Electronic Health Records (EHRs) and standards to exchange EHRs have improved various aspects of health practices and patient care. However, the data captured in an EHR is only accessible to the providers and specialists within an organization, but not the patient. The concept of a Personal Health Record (PHR) is to allow the patients to record and manage their health data beyond EHR and if possible, see the EHR data in the PHR. Experts agree that bi-directional communication between the PHR and EHR allows the PHR to be more effective and a valuable tool for both the providers and patients. Communicating near real-time patient recorded data in PHR with an EHR will allow the provider(s) to make appropriate clinical decisions and patients can see any changes to his/her diagnostics or treatment plans. This research explores and critically analyzes HL7 FHIR to design and prototype an interoperable mobile PHR that conforms to the HL7 PHR Functional Model and allows bi-directional communication with OpenEMR.

This paper focuses on value sets as an essential component in the health analytics ecosystem. We discuss shared repositories of reusable value sets and offer recommendations for their further development and adoption. In order to motivate these contributions, we explain how value sets fit into specific analytic tasks and the health analytics landscape more broadly; their growing importance and ubiquity with the advent of Common Data Models, Distributed Research Networks, and the availability of higher order, reusable analytic resources like electronic phenotypes and electronic clinical quality measures; the formidable barriers to value set reuse; and our introduction of a concept-agnostic orientation to vocabulary collections. The costs of ad hoc value set management and the benefits of value set reuse are described or implied throughout. Our standards, infrastructure, and design recommendations are not systematic or comprehensive but invite further work to support value set reuse for health analytics. The views represented in the paper do not necessarily represent the views of the institutions or of all the co-authors.

In the patient-centered medical home, PCMH, patient care is overseen by a primary care physician leading a team of health care providers, who collaborate to optimize treatment. To facilitate interactions in PCMH, secure collaboration will be needed to: control access to information; dictate who can do what when; and promote sharing and concurrent access. This contrasts approaches such as the National Institute of Standard and Technology (NIST) role-based access control (RBAC), where the emphasis is on controlling access and separating responsibilities. This paper investigates secure collaboration within an application such as PCMH, through: a futuristic scenario for patient care; proposed collaboration extensions to the NIST RBAC standard with a fine-grained obligated mechanism and workflow; and a prototype of PCMH via the Google Wave real-time collaboration platform.
