OpenEHR Implementation Guide: Towards Standard Low-Code Healthcare Systems.

Several open source components have been made available in recent years to help develop full openEHR systems. Still doubts exist if these are sufficient. This paper presents a case study of implementing a low-code openEHR system, investigating the feasibility and challenges of developing a system using these components for each step. The method used consisted in selecting successful examples of implementation case studies, identifying key development steps, and for each step searching for possible open source options. As a result, we had a working low-code openEHR powered EHR, successfully demonstrating the feasibility of the proposed implementation guide. The main available free or open source components used were ArchetypeDesigner and EHRbase, developed by Better and Vita/HighMed respectively. In our opinion, it is possible to build EHR systems using the available open source components, but support is still missing in the front end, specifically for form generation and screen representation.
