Siilo | Practice Medicine Together


“Siilo has great potential to control and manage major incidents. We’ve seen the benefits of WhatsApp in these situations, but with Siilo the benefits are even greater — it’s highly intuitive, familiar and it’s ready to use.”
– Darren Lui, Spinal and Orthopaedic Surgeon at St George’s Hospital, UK

“Regional networks require optimal collaboration between primary and secondary care. By creating a regional network together with primary care physicians, we can effectively serve all people affected. With Siilo, the Red Cross Hospital specialists are demonstrating leadership by sharing knowledge and expertise, even beyond hospital walls.”
– Dr. Gonneke Hermanides, Infectious Disease Specialist, Red Cross Hospital Beverwijk Netherlands

“The possibilities we have with Siilo are enormous because we can receive very quick responses from our clinical peers securely from all over the country and benefit from different opinions on how best to treat patients.”
– Professor Holger Nef, cardiologist and deputy medical director at The University Hospital of Giessen and director of the Heart Centre Rotenburg

“Everyone has interesting patient cases, but that information is not stored nationwide. With Siilo you can search the cases and see if someone asked the question before.”
– Anke Kylstra, AIOS Hospital Pharmacy in the Maxima Medical Center, JongNVZA board member

This app has fully met requirements to date. Easy to navigate, with good support. Experienced some issues with bugs which have since been resolved, and some dissatisfaction around verification process, but overall, happy with app.

App was working fine until an update was made and now it won't even open and reboots my phone. Initially I was told it is an android 4 5 or 6 problem even though I had already explained I use android 10. I am now missing communications and no idea when it will be fixed. Nice app but support can be improved.

Beste Ellen, excuses voor dit probleem, dat veroorzaakt wordt door een bug in de Samsung A10. Deze telefoon crasht wanneer apps (zoals Siilo) gebruik maken van face unlock. Bij onze laatste versie speelt dit probleem niet meer, dus je kunt het beste Siilo even updaten. Laat ons weten als je nog meer vragen hebt! Team Siilo

I don't like the fact that you have to use your phone number to make an account. email should suffice. my employer only provides an iPad to use for work purposes but requires that you use this app for communication but I don't get compensated for my cell phone bill. Consider using email or account setup please and thank you.

Hi Salina, thank you for your feedback! The reason we require a phone number is that this allows you to easily find other medical professionals who are also members of Siilo and are in your phone's address book. We will take your feedback into account and consider other options in future versions! More questions? Please contact Siilo Service Desk.
