The WHOPEN Application is developed as a tool facilitate the implementation of essential Non communicable diseases (NCD) interventions for primary health care. This is intended to be used by a health provider and not by individuals. It contains materials from the WHO package of essential noncommunicable (PEN) disease interventions for primary health care. Geneva, World Health Organization; 2020. The WHOPEN App brings together the guidelines and protocols that are adaptable to local settings and able to empower primary care physicians, as well as allied health workers, to contribute to NCD management. WHOPEN App includes a CVD risk calculator through which the user will be able to predict the 10-year risk of a fatal or nonfatal major cardiovascular event (myocardial infarction or stroke). WHOPEN is not meant to be exhaustive or prescriptive, but rather to be an important first step for integration of NCD management into primary health care. Tools for adapting the package to primary health care and capacity building materials such as slides, and posters are also included.
