In 2009, Philips Refurbished Systems donated two ultrasound machines to the two public hospitals in Chinandega, North of León. Within half a year, both machines were broken down due to lack of power stabilization and preventive maintenance. In order to improve the care and sustainability for donated X-ray and Ultrasound equipment, an NGO of former CEO's of Philips Medical Systems was founded under the name of NICHED (Nicaraguan healthcare and education), with Willem Vuisting,  Ben Wijdeveld and Martien van Overeem as members of the board. Since then, a range of refurbished X-ray and Ultrasound systems have been donated to various public hospitals in Nicaragua. An agreement with the Ministery of Health (MINSA) for a budget for preventive maintenance has been reached, allowing a sustainable improvement of the radiological care in Nicaragua.
