The Evidence-Based Medicine electronic Decision Support (EBMeDS) system brings evidence into practice by means of context-sensitive guidance at the point of care.

EBMeDS receives structured patient data from electronic health records (EHRs) and returns reminders, therapeutic suggestions and diagnosis-specific links to guidelines. It can also be used to automatically prefill forms and calculators with patient specific data. In addition to real-time use, the EBMeDS decision support rules can also be run in patient populations ("virtual health checks").

EBMeDS is a platform-independent service, which can be integrated into any EHR containing structured patient data. It is based on a simple but efficient technology, and both installing and updating the system is easy.

EBMeDS is developed by Duodecim Medical Publications Ltd, a Finnish company owned by the Finnish Medical Society Duodecim. Both the association and the company have a long-standing collaborative relationship with the Cochrane Collaboration, the GRADE Working Group, the Guidelines International Network (G-I-N) and the publishing company Wiley-Blackwell.

All end-users of the EBMeDS service can contribute to the development of new scripts. The simplest way of contribution is to send a suggestion of a script idea to the EBMeDS editorial team. End-users are also offered free access to the EBMeDS Script Description Editor (ESDE), a web-based editing tool for collaboratory development of evidence-based decision support rules. The use of ESDE requires registration.
