    In order to support innovation, the Society of Imaging Informatics in Medicine (SIIM) elected to create a collaborative computing experience called a "hackathon." The SIIM Hackathon has always consisted of two components, the event itself and the infrastructure and resources provided to the participants. In 2014, SIIM provided a collection of servers to participants during the annual meeting. After initial server setup, it was clear that clinical and imaging "test" data were also needed in order to create useful applications. We outline the goals, thought process, and execution behind the creation and maintenance of the clinical and imaging data used to create DICOM and FHIR Hackathon resources.

    Examining the effect of peer helping in a coping skills intervention: a randomized controlled trial for advanced gastrointestinal cancer patients and their family caregivers
    (Springer Nature, 2018-02) Kohli, Marc; Morrison, James J.; Wawira, Judy; Morgan, Matthew B.; Hostetter, Jason; Genereaux, Brad; Hussain, Mohannad; Langer, Steve G.; Psychology, School of Science
    PURPOSE: At the end of life, spiritual well-being is a central aspect of quality of life for many patients and their family caregivers. A prevalent spiritual value in advanced cancer patients is the need to actively give. To address this need, the current randomized trial examined whether adding a peer helping component to a coping skills intervention leads to improved meaning in life and peace for advanced gastrointestinal cancer patients and their caregivers. Feasibility and acceptability outcomes were also assessed. METHODS: Advanced gastrointestinal cancer patients and caregivers (n = 50 dyads) were randomly assigned to a 5-session, telephone-based coping skills intervention or a peer helping + coping skills intervention. One or both dyad members had moderate-severe distress. Peer helping involved contributing to handouts on coping skills for other families coping with cancer. Patients and caregivers completed measures of meaning in life/peace, fatigue, psychological symptoms, coping self-efficacy, and emotional support. Patient pain and caregiver burden were also assessed. RESULTS: Small effects in favor of the coping skills group were found regarding meaning in life/peace at 1 and 5 weeks post-intervention. Other outcomes did not vary as a function of group assignment, with both groups showing small decreases in patient and caregiver fatigue and caregiver distress and burden. High recruitment and retention rates supported feasibility, and high participant satisfaction ratings supported acceptability. CONCLUSIONS: Although a telephone-based intervention is feasible and acceptable for this population, peer helping in the context of a coping skills intervention does not enhance spiritual well-being relative to coping skills alone.

    A Platform for Innovation and Standards Evaluation: a Case Study from the OpenMRS Open-Source Radiology Information System
    (Springer, 2018-05-10) Gichoya, Judy W.; Kohli, Marc; Ivange, Larry; Schmidt, Teri S.; Purkayastha, Saptarshi; Radiology and Imaging Sciences, School of Medicine
    Open-source development can provide a platform for innovation by seeking feedback from community members as well as providing tools and infrastructure to test new standards. Vendors of proprietary systems may delay adoption of new standards until there are sufficient incentives such as legal mandates or financial incentives to encourage/mandate adoption. Moreover, open-source systems in healthcare have been widely adopted in low- and middle-income countries and can be used to bridge gaps that exist in global health radiology. Since 2011, the authors, along with a community of open-source contributors, have worked on developing an open-source radiology information system (RIS) across two communities-OpenMRS and LibreHealth. The main purpose of the RIS is to implement core radiology workflows, on which others can build and test new radiology standards. This work has resulted in three major releases of the system, with current architectural changes driven by changing technology, development of new standards in health and imaging informatics, and changing user needs. At their core, both these communities are focused on building general-purpose EHR systems, but based on user contributions from the fringes, we have been able to create an innovative system that has been used by hospitals and clinics in four different countries. We provide an overview of the history of the LibreHealth RIS, the architecture of the system, overview of standards integration, describe challenges of developing an open-source product, and future directions. Our goal is to attract more participation and involvement to further develop the LibreHealth RIS into an Enterprise Imaging System that can be used in other clinical imaging including pathology and dermatology.
