Call-4-Help (https://call-4-help.ai) ensures hospital staff can find the resources they need quickly, easily and securely. It helps make treatment quicker, safer and more efficient, avoiding the waste of precious PPE by reducing the number of transitions staff have to make in & out of hot areas. Underlying Call-4-Help is a smart app designed to improve communications between healthcare professionals within hospitals. Large numbers of non-ICU specialist health care workers are being very rapidly retrained to work in intensive care units around the world. People frequently need help: getting the right equipment, medicines and supplies where they are needed, finding the right person to call in, or often just getting questions answered. Until now that’s often been done with large WhatsApp groups, which can be chaotic, inefficient and insecure. Call-4-Help's mission is to make life easier for hospital staff, to simplify communications in order to help patients.
