Jan-Marc Verlinden is the founder and CEO of MedVision360. MedRecord, their flagship project, is an eHR (electronic Health Record) system: everything from patient data to digital health apps, devices, wearables, companies and hospital systems are wrapped together, providing a single platform on which healthcare providers can build medical applications and expose data and services via APIs. Currently, the MedVision platform is used in over 8 large EU projects, including hospitals from Hannover to Rome to Southampton.
At WSO2Con EU 2015, Jan-Marc took the stage to explain how MedVision360 achieved all this: using WSO2 products at the heart of their platform, with expertise from our partner, Yenlo.
Inside the medicine cabinet
MedRecord was born of a desire to do better. Europe, says Jan-Marc, is aging; by 2020, there will be 3 working people to every old person. In China, this problem is bound to be even more serious. This is a huge challenge for healthcare.
Given the severity of this situation, one would imagine this problem would have been tackled ages ago. Not so.
According to Jan-Marc, there are a few major problems in the way of change coming in with effective use of ICT; cost, concerns – or technical ignorance- about privacy and data security, a lack of communication between ICT systems, and the human capital it costs for data entry.
There’s also the lack of financial incentives to do better. There’s no real incentive for doctors to change the way they work and to reduce those long queues to something as simple as a mobile app, especially given the costs faced.
MedVision360 built two stacks: the first, which they subsequently open sourced, uses XML for storing data – and a second, enterprise version, with better performance using PostgreSQL. Both are based on the CEN/ISO EN 13606 standard, which requires the platform to use a dual-model architecture that maintains a clear separation between information and knowledge.
To convey the depth of modelling involved in this, Jan-Marc used the example of blood pressure, one of the many measurements involved in the process of treating a patient.
This is the type of semantic model template developed by the NHS (the National Health Services, UK). The idea is that this delivers both the data needed and the context that a medical specialist would need to frame the data in. As the system consumes these archetypes, it becomes instantly proficient.
However, due to different workflows and standards, a doctor in a country other than the UK might require a different version of things, as seen above; not just a 1-1 translation of terms, either.
Working with Yenlo, MedVision360 utilized the open source WSO2 API Manager, WSO2 App Manager, and WSO2 Identity Server to solve this issue. WSO2 API Manager is a complete solution for designing and managing the API lifecycle after publishing. MedRecord’s architecture uses API manager to expose the data in the MedRecord platform from the PaaS layer, while managing access rights. WSO2 Identity Server enables login through third party identity providers (like Google and Netherland’s UZI-pass), handling role based access control and providing an audit trail.
Everything else – applications, websites – is hosted on this layer. Swagger and JSON make it easier to build validated apps. Paired with a drag-and-drop HTML5 tooling interface, developers can easily build applications by accessing functionality from APIs with a few clicks. Hooks to portals like Drupal and Liferay allow better, device-independent presentation of content.
This opens up possibilities even for integration with Google Fit or Apple Health Kit. Google Fit, for example, collects data on the patient walking and so on; while that’s not relevant for a doctor, who’s more concerned with the patient not walking, parsing and analyzing the data would allow medical professionals to keep an eye on their customers’ health.
Healthcare is a very serious business, and at WSO2, we’re glad that providers like MedVision360 – and their clients- have chosen to trust our platform with the lives of others. To examine the full video of Jan-Marc Verlinden’s talk, click here.
