The future of health is in #opendata


This Saturday I had the pleasure of helping organize a hackathon that was put together by the Open State Foundation (HackDeOverheid). The theme was “Open Data, open for business” and took place at a very unique place in Rotterdam - WORM (an institute for avant garde recreation). It was a perfect spot to gather almost 150 people from all disciplines and sponsors/partners ranging from the Hogeschool Rotterdam, TNO, Internet Valley Rotterdam to name a few, but also a contribution from Health 2.0


Open health data is relatively a new initiative within the Open State Foundation with a simple but strong message:

"Open Zorg Data is an initiative to build a community that utilizes open healthcare data, encourages innovation & entrepreneurship, improves transparency in our healthcare system and most importantly turns healthcare into health for out digital citizens”

In the last few weeks, we worked with the Ministry of Health (Ministerie van VWS) to plan out the OpenZorgData Workshop and help inspire the community of developers to use the data for social and entrepreneurial good.

The turn out was great!!  We have more then doubled (2X) the number of attendees to the workshop from the previous workshop that took place in Amsterdam. First up in the morning data pitch session was, Ron Roozendaal (CIO of the Ministry of Health), who took a few minutes to introduce all the stakeholders within the Ministry and the newly opened data sets. His enthusiasm and excitement exuded itself for sure!


Our workshop kicked off at 11:45 with standing room only, but when I asked how many people were hackers planning to use the open health data, only one guy raised his hand (but noted that he had no plans of doing it that day). Here we are: room full of people, Ministry of Health in the room and not one single individual was planning to hack away at the data. We carried on with the presentations where Lany Slobbe, Hans Loonen & Christian Gonzales presented their respective data sets. The workshop presentations finished off with Seth van den Bossche from TNO presenting their open data & Atilla Erdodi showcasing an open API he put on top of the KiesBeter data (opened up back in June of 2012).

This is when I saw a few more young guys on the floor and these were the guys that saved


the day for Open Zorg Data. Jan-Willem Manenscijn, Jens de Waard & Rik Nijessen, students from Delft decided to use the data form TNO and combined it with Rotterdam open data from GGD to create a small app that would allow citizens, to look for specific zip code (Rotterdam only for now) and get a rating of the neighborhood based on healthcare, environment, lifestyle and safety scores - all that in just under 6 hours

I was honored to be on the judging panel with Geerten Eijkelenboom, Director of Rotterdam Internet Valley, Paul Rutten who is an influential researcher and two others. We had a tough decision to make for the three prizes (1 for Mobility, 1 for Health and 1 for overall business concept). Together we decided not to award a mobility prize given the app did not fully use the data elements, however that same team did win the overall business concept prize (the idea is similar to Blue Book Car Value).

For health, we did decide to award the 500 Euro prize sponsored by Health 2.0 to the one and only team that showcased their innovation in pulling together disparate data sets. But here are some more great news: all three guys also got awarded FREE conference tickets to Health 2.0 Berlin as well as a second 1,750 Euro spot prize form the Rotterdam Internet Valley if they take their concept further.

This is great news for OpenZorgData community to inspire more developers to use health data to create apps. This is also great news for the Ministry of Health, since the next

Ministry of Health

release of the above app, will use the additional data sets already opened to overlay into the overall score (for ex Cost of Illness data).

But most importantly, this is great news for the citizens of Netherlands - the seemingly small but sure steps that the Ministry has taken to show the importance of working with the community to help us, the digital citizens, make better choices when it comes to health!

Once again congratulations to Jan-Willem Manenscijn, Jens de Waard & Rik Nijessen for helping OpenZorgData off the ground!

I look forward to continue growing this young community of innovators!

Health 2.0 & OpenZorgData hackathon update on new datasets


Only two days left before the Open State Foundation Rotterdam Hackathon on October 13th. For all those attending the OpenZorgData workshop and those who are ready to hack away at the data there are some more great news. In my previous post I described a few datasets that have been opened by the Ministry of Health and wanted to provide an update to two more that are now published for use.

Existing datasets

BIG-register which provides information on over 400,000 registered caregivers, last updated in August of this year

KiesBeter (Choose Better) - this dataset was opened up in June with the latest update this past August. We already have an API that was put together by Atilla to access this data via a web service - more to come at the workshop

Kosten van Ziekten (Cost of Illnesses) - This data has been open since October 1st - so go ahead and take it for a ride!

New datasets 

Regelhulp - content is still king, so now you can use Regelhulp and embed it into your site or use the SQL database they provided which has content in it for you to use as is.

Here are some more details on access and the datasets:

  • The service can be accessed and viewed via the following hyperlink
  • Application can be accessed through: Beheer omgeving
  • Username: hackathon Password: hackathon2012

Furthermore content has been provided exclusively for the  hackathon (SQL database) of all Regelhulp content items. I uploaded and shared all the associated documentation and css files here

Jaarverslagenzorg - Datasets are now available in Excel and SPSS formats and can be found here

Will you be there to change healthcare into health?

Health 2.0 Amsterdam Chapter Event: Focus Hospital care

I would like to announce our next event, which will take place on October 18th at DesignThinkers Amsterdam.

This event will have a special focus on hospitals and patient experience inside and outside these institutions.


18:30     -   Networking & “Healthy Snacks”

19:00     -   Introductions & OpenZorgData hackathon update (Eugene/Atilla)

19:30     -   Hospitality App, dr. Marlies Schijven

20:00     -   Synappz Medical Apps, Erik van der Zijden

20:30     -   Networking

Our first presenter will be Marlies Schijven, who is a surgeon at the Amsterdam Medical Center and also a recent winner of the “Vodafone Mobiles for Good” prize competition in the “Healthy aging” category. This competition took place at the recent PICNIC Festival right here in Amsterdam.

The Hospitality App, focuses on the experience inside the hospital and allows an elderly person to be accompanied by a medical student assistant to, and during a consultation with a doctor. The patient then has a less stressful walk through the hospital, is able to follow the consultation better, and may ask questions about the provided information afterwards.

We will also hear form Erik van der Zijden from Synnappz Medical Apps, whose flagship product is an app that helps patients track, record and report their bladder trends. While a very niche product, there is an amazing need need to bring continuous real time feedback and improve the current paper-and-pen method in order to improve patient experience and therefore improve patient health.

We will close with an update of the OpenZorgData hackathon that is taking place in Rotterdam, this Saturday October 13th, where Ministry of Health will be opening up additional data sets for our community to come up with entrepreneurial ideas to improve our healthcare system. See more information on my blog

Looking forward to continue building a strong Health 2.0 community here in Amsterdam, and as always please continue to provide feedback. Best place to reach me is on Twitter

Since this is a FREE event and the space is limited, please only RSVP with a yes if you are sure you can make it. You can always reach out to me for last minute changes.

Will I see you there?

Exclusive invitation to change healthcare with #opendata


On behalf of the Open State Foundation & HackDeOverheid, I would like to extend a personal invitation to the #openzorgdata workshop which will take place on October 13th in the city of Rotterdam. We would love your participation in this workshop to discuss the future of open health data and come out with actionable next steps to continue growing this community. While health is personal, there is a greater social impact on the future of the relationship between us, the digital citizens and our governments. This socially impacting community of open health data can and will drive innovation, spur entrepreneurship and drive transparency into an industry that is prime for a transformation. Together, we can connect, create and ultimately cure!

This workshop will kickoff at 11:45 and we are honored to have the Ministry of Health present current and new open data sets which will include:

Kosten van Ziekten (Cost of Illnesses) - this is breaking news and was just opened up today, October 1st

BIG-register which provides information on over 400,000 registered caregivers, last updated in August of this year

KiesBeter (Choose Better) - this dataset was opened up in June with the latest update this past August and provides information on hospitals: name, address and contact details, specializations, polyclinics, general services and medical facilities (how about a mobile app?)

Regelhulp - no official announcement on the open data that will be provided so stay tuned. This portal provides content and information on healthcare, welfare, parenting and more. 

Jaarverslagenzorg - no official announcement on the open data yet either but hold your horses - it is coming.. Take a look at the site to imagine what data could be opened up publicly.

This hackathon is also sponsored by Health 2.0 with a prize of €500 for the best prototype app based on the open health data available. If you know great developers, hackers, geeks please spread the word to register but this is obviously not limited to only that audience. We do want practitioners, physicians, nurses, caregivers and all of us, healthcare consumers, to participate in building this community!
