We've seen the benefits of WhatsApp in these situations, but with Connect 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 SARS-CoV-2 pandemic requires optimal collaboration between primary and secondary care. By creating a regional network together with primary care physicians, we can effectively serve all people affected by this virus. With Connect, 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 Connect 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.
