Dear Koray, A metric from real practice: - Porting one application from its original database to Ocean Informatics EhrGate took two weeks. Including the production of a SOAP and .Com interface of the interface of Oceans product.
Problems: - How do you put figures to the fact that no longer data base conversions are needed? - How do you put figures to the fact that no longer data is lost because of this? - How do you put figures to the fact that without reprogramming Healthcare Providers are able to define themselves what data and information they have to store, retrieve, present and exchange and that they do not need the help of the EHR-system vendor? - How do you put figures to the fact that vendor lock-in is no longer an issue? - How do you put figures to the fact that since products based on openEHR/Ocean are a generic tool instead of a proprietary product customized for a specific enterprise or department at great cost? - How do you put figures to the fact that systems based on openEHR/ Ocean enable flexibly all ever changing work processes thereby facilitating innovation and market competition? - How do you put figures to the fact that systems based on openEHR/ Ocean never enforces all users to use one set of messages based on one standardized business process?
