We present a software architecture that federates data from multiple heterogeneous health informatics data sources owned by multiple organizations. The architecture builds upon state-of-the-art open-source Java and XML frameworks in innovative ways. It consists of (a) federated query engine, which manages federated queries and result set aggregation via a patient identification service; and (b) data source facades, which translate the physical data models into a common model on-the-fly and handle large result set streaming. System modules are connected via reusable Apache Camel integration routes and deployed to an OSGi enterprise service bus. We present an application of our architecture that allows users to construct queries via the i2b2 web front-end, and federates patient data from the University of Utah Enterprise Data Warehouse and the Utah Population database. Our system can be easily adopted, extended and integrated with existing SOA Healthcare and HL7 frameworks such as i2b2 and caGrid.
Background: Management of ascites-related symptoms in home hospice and palliative care patients can be challenging. Ultrasound-guided paracentesis is a standard intervention for this indication, but generally requires transfer to a hospital or outpatient interventional-radiology (IR) setting; thus, such interventions are often not practical or attainable for home hospice and palliative care patients. Objective: To describe a mobile, in-home service that provides home-based palliative paracentesis (HBPP) as an interventional palliative option for patients with distressing symptoms related to ascites. Design: Retrospective case series. Setting/Subjects: Thirty patients with ascites, confirmed by portable bedside ultrasound, who underwent HBPP at their residence. Results: Thirty-three patients were referred for HBPP for symptomatic abdominal distention from March 1, 2019 to March 1, 2020. Thirty (91%) patients had ultrasound-confirmed ascites and received HBPP. All 30, verbalized appreciable symptom relief post-intervention. There were no reported post-procedural complications. Conclusion: Home-based palliative paracentesis is a safe, effective, and convenient intervention for hospice and palliative care patients with symptomatic ascites.

A demonstration of the system using mock implementations is presented; we are currently working on integrating live data sources.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
