Prehospital notification by emergency medical services (EMS) can activate hospital resources before the patient arrives, which has been shown to improve in-hospital care for stroke patients. Optimising prehospital and handover processes in stroke care requires considering end-user perspectives to enhance acceptance and effectiveness of the developed solutions. The aim of this study was to identify current barriers in the preclinical-clinical phase of stroke care.

Within the investigator-initiated CAEHR project (CArdiovascular diseases—Enhancing Healthcare through cross-sectoral Routine data integration), an interface for transferring data from the electronic prenotification system to the hospital information system is implemented. A mixed-methods approach with semi-structured interviews as well as a cross-sectional online survey was used to gather feedback from healthcare professionals at a single stroke centre in Germany as well as from the participating EMS personnel. Data collection for the interviews was conducted between January and August 2023 and for the online survey between May and September 2023.

Interviews were conducted with 10 healthcare professionals, including seven from the neurological clinic and three from EMS. Additionally, 39 EMS employees took part in a cross-sectional online survey.

Challenges identified were educational and training aspects affecting preclinical processes and patient handover procedures, along with the opportunity for establishing more uniform protocols. Participants emphasised the importance of detailed patient information. Electronic prenotification was seen as an important step regarding structured information transmission, reducing the risk of information loss in stroke care.

The study highlights the importance of addressing organisational processes in addition to technical interfaces for implementing effective stroke care processes.

Digitalisation in healthcare has resulted in fragmented solutions and limited interoperability. The Fast Healthcare Interoperability Resources (FHIR) standard is increasingly adopted to enable standardised data exchange, yet its complexity creates usability challenges for clinicians and developers. To address these challenges, this study evaluates the usability of an enhanced FHIR Questionnaire Resource Editor designed to improve workflow efficiency, accessibility and user satisfaction in creating and managing healthcare questionnaires.

This mixed-methods usability evaluation will recruit 10 healthcare professionals and/or informatics experts via convenience sampling. The study will consist of four general phases: (1) an initial session to familiarise users with the tool; (2) a task analysis phase supported by eye-tracking to identify strengths and weaknesses; (3) retrospective think-aloud interviews to explore strategies used during tasks and (4) completion of a validated usability questionnaire, such as the System Usability Scale, to quantify user satisfaction. We will analyse quantitative data using descriptive and inferential statistics. Qualitative feedback will be examined through thematic analysis and affinity mapping. The primary outcome is to assess the editor’s usability and accessibility and to identify areas for improvement.

This study protocol has been reviewed and approved by the Ethics Committee of the Medical Faculty at the University of Würzburg (ethikkommission@uni-wuerzburg.de) under approval number (24/24-sc). All participants will provide informed consent. Results will be disseminated through peer-reviewed journals, conferences and open-access platforms to inform future iterations of FHIR-based tools.
