Linked Care: A Harmonized Workflow for Medication Ordering, Prescription and Dispensing in Mobile Care Settings.

The growing demand for care amid changing demographics poses significant challenges exacerbated by decreasing healthcare professional availability. In Austria, the Linked Care project aims to address these challenges by developing an intersectoral, harmonized IT-supported workflow for medication ordering, prescription, and dispense in mobile care settings. A human centered design approach, with user-focused interviews and workshops was used to identify requirements and analyze the workflows. Activity diagrams were used represent workflows. The resulting harmonized workflow, developed through iterative collaboration with care organizations, integrates the LC platform into existing care software. To test and demonstrate the harmonized workflow, mockups were created and evaluated for usability, resulting in positive feedback and suggestions for enhancements. Current workflows revealed media breaches and inefficiencies, which the proposed harmonized workflow seeks to address. The paper concludes with implications for future developments, including the subsequent adoption of a HL7 FHIR Implementation Guide for Austria, based on the defined harmonized workflow, to streamline intersectoral communication and improve efficiency in mobile care settings.

Development of an Austrian HL7 Member FHIR IG Supporting Medication Ordering, Prescription and Dispense Processes.

The Austrian research project Linked Care explored digitalization in mobile care, focusing on streamlining the medication process to save nursing staff time. A FHIR R5-based workflow was developed to support medication ordering by nurses, prescriptions by practitioners, and dispensing by pharmacies. Key FHIR resources were profiled and published in an HL7 Austria Member Implementation Guide (IG). The IG includes specifications and technical details for implementation and was the first member-contributed IG approved by the HL7 Austria FHIR community in early 2024. These specifications are now being implemented and will be tested in late 2024.

ELGA Outpatient Clinic Report and ELGA Telehealth Note: Two HL7-CDA®-Based Modular Electronic Documents.

BACKGROUND: From 2022, the "Outpatient Clinic Report" and the "Telehealth Note" will complement the existing e-Reports in the Austrian Electronic Health Record system ELGA. OBJECTIVES: The specification of two harmonized implementation guides with standardized structure for all types of outpatient clinics in hospitals on the one hand and for telemonitoring treatments on the other hand. METHODS: With the participation of expert groups, the contents were harmonized, and a data model was created. Template specifications were modelled in ART-DECOR and approved in the course of an HL7 Austria ballot. RESULTS: Two sets of freely selectable building blocks and machine-readable content were created. CONCLUSION: The "Outpatient Clinic Report" and the "Telehealth Note" are currently being implemented. The use of these documents will be evaluated as well as if additional machine-readable content is needed.

Development of a Protocol for Automated Glucose Measurement Transmission Used in Clinical Decision Support Systems Based on the Continua Design Guidelines.

BACKGROUND: A fast and accurate data transmission from glucose meter to clinical decision support systems (CDSSs) is crucial for the management of type 2 diabetes mellitus since almost all therapeutic interventions are derived from glucose measurements. OBJECTIVES: Aim was to develop a prototype of an automated glucose measurement transmission protocol based on the Continua Design Guidelines and to embed the protocol into a CDSS used by healthcare professionals. METHODS: A literature and market research was performed to analyze the state-of-the-art and thereupon develop, integrate and validate an automated glucose measurement transmission protocol in an iterative process. RESULTS: Findings from literature and market research guided towards the development of a standardized glucose measurement transmission protocol using a middleware. The interface description to communicate with the glucose meter was illustrated and embedded into a CDSS. CONCLUSION: A prototype of an interoperable transmission of glucose measurements was developed and implemented in a CDSS presenting a promising way to reduce medication errors and improve user satisfaction.

Bluetooth Low Energy Peripheral Android Health App for Educational and Interoperability Testing Purposes.

Based on recent telemonitoring activities in Austria for enabling integrated health care, the communication interfaces between personal health devices (e.g. blood pressure monitor) and personal health gateway devices (e.g. smartphone, routing received information to wide area networks) play an important role. In order to ease testing of the Bluetooth Low Energy interface functionality of the personal health gateway devices, a personal health device simulator was developed. Based on specifications from the Bluetooth SIG a XML software test configuration file structure is defined that declares the specific features of the personal health devices simulated. Using this configuration file, different scenarios are defined, e.g. send a single measurement result from a blood pressure reading or sending multiple (historic) weight scale readings. The simulator is intended to be used for educational purposes in lectures, where the number of physical personal health devices can be reduced and learning can be improved. It could be shown that this simulator assists the development process of mHealth applications by reducing the time needed for development and testing.

Propose of Standards Based IT Architecture to Enrich the Value of Allergy Data by Telemonitoring Data.

Interoperability is a key requirement for any IT-System to be future proof and cost efficient, due to the increasing interaction of IT-Systems in Healthcare. This feasibility study is part of a larger project focusing on the conceptualization and evaluation of interoperable and modular IT-Framework components for exchanging big data information sets. Hence, this project investigates the applicability of a standard based IT-Architecture for the integration of Personal Health Devices data and open data sources. As a proof of concept use case, pollen forecast data from the Medical University of Vienna were combined with Personal Health Device data and a data correlation was investigated. The standards were identified as well as selected in expert's reviewed and the Architecture was designed based on a literature research. Subsequently the prototype was implemented and successfully tested in interoperability tests. The study shows that the architecture meets the requirements. It can be flexibly extended according to further requirements due to its generic setup. However, further extensions of the Interoperability-Connector and a full test setup needs to be realized in future.

Biosignals, Standards and FHIR - The Way to Go?

BACKGROUND: Standards have become available to share semantically encoded vital parameters from medical devices, as required for example by personal healthcare records. Standardised sharing of biosignal data largely remains open. OBJECTIVES: The goal of this work is to explore available biosignal file format and data exchange standards and profiles, and to conceptualise end-to-end solutions. METHODS: The authors reviewed and discussed available biosignal file format standards with other members of international standards development organisations (SDOs). RESULTS: A raw concept for standards based acquisition, storage, archiving and sharing of biosignals was developed. The GDF format may serve for storing biosignals. Signals can then be shared using FHIR resources and may be stored on FHIR servers or in DICOM archives, with DICOM waveforms as one possible format. CONCLUSION: Currently a group of international SDOs (e.g. HL7, IHE, DICOM, IEEE) is engaged in intensive discussions. This discussion extends existing work that already was adopted by large implementer communities. The concept presented here only reports the current status of the discussion in Austria. The discussion will continue internationally, with results to be expected over the coming years.

Applicability of IHE/Continua components for PHR systems: learning from experiences.

Capturing personal health data using smartphones, PCs or other devices, and the reuse of the data in personal health records (PHR) is becoming more and more attractive for modern health-conscious populations. This paper analyses interoperability specifications targeting standards-based communication of computer systems and personal health devices (e.g. blood pressure monitor) in healthcare from initiatives like Integrating the Healthcare Enterprise (IHE) and Continua Health Alliance driven by industry and healthcare professionals. Furthermore it identifies certain contradictions and gaps in the specifications and suggests possible solutions. Despite these shortcomings, the specifications allow fully functional implementations of PHR systems. Henceforth, both big business and small and medium-sized enterprises (SMEs) can actively contribute to the widespread use of large-scale interoperable PHR systems.

LUMOR: an app for standardized control and monitoring of a porcine lung and its nutrient cycle.

The outcome of the EU-funded project ElBik has been the lung simulator 'iLung', which imitates an actively breathing human lung with a porcine lung. In order to keep the explanted lung in a nearly physiological state during transportation from the slaughterhouse to the ventilation laboratory the tissue needs to be nourished and temperature controlled. The Project AlveoPic designs a mobile transport vehicle implementing an ISO/IEEE 11073-20601 compliant communication interface for the exchange of the physical parameters, alert messages and setpoint-values. An appropriate 11073 domain information model is designed and limitations of the defined services and attributes are identified. For monitoring purposes the Android App LUMOR is implemented providing a user with an easy-to-handle GUI. It was found, that alert capabilities and remote set features are not well supported in ISO/IEEE 11073-20601 at the moment and possible workarounds are discussed.
