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

“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, a 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

Fijne app

Deze app werkt goed, doet waar hij voor gemaakt is. Ook fijn dat de berichten automatisch worden verwijderd na 30 dagen.
1 minpuntje, en dat is dat je binnen de app niet op berichten kunt antwoorden. Soms lopen 2 gesprekken door elkaar en is het fijn om op een bericht/antwoord te kunnen antwoorden. Zouden jullie die functionaliteit kunnen toevoegen? Doorsturen kan wel maar beantwoorden kan niet binnen de app.

Developer Response ,

Hallo Dvaniersel

Bedankt voor de feedback op onze app. Dat waarderen we enorm. De swipe to quote feature staat bij ons op de roadmap. Nog even geduld graag. Je kan vandaag overigens met de "cases feature" meerdere gesprekken naast elkaar voeren in zowel groepen als 1 op 1. Je kan een case starten in een conversatie door op het plusje te klikken en "case aanmaken" selecteren.

Met vriendelijke groet,
Team Siilo

Fijne veilige app voor uitwisseling medisch- vertrouwelijke berichten

Snel te begrijpen bediening, na 30 dagen worden de berichten gewist, opslaan is ook mogelijk. Goede help-desk bij vragen, snel en adequaat antwoord. Grotere bestanden ook snel in te voegen en te versturen.Kortom: een aanrader!
