Up to 15,000 patients in Germany die from hospital infections each year. The essential factor in the fight against multiresistant germs is hygiene. With a new approach HygNova Medical makes it easier for hospital staff to take the necessary precautionary measures: a tablet in the room asks nurses and doctors to disinfect their hands by sending light and sound signals. Those who degerm are rewarded - for example, with a financial bonus or virtual praise. Moreover, sensors record disinfections that have been carried out, thus providing more transparency. The aim of the start-up HygNova is to reduce hospital infections by up to 68 per cent.
