Venous thromboembolism (VTE), clinically presenting as deep vein thrombosis or pulmonary embolism (PE) is the third most frequent cardiovascular disease and is associated with substantial short- and long-term morbidity and mortality and high costs of care. In addition negative physical and mental complications following VTE are common. However in terms of PE, there are no structured follow-up programs in Denmark and there is considerable variation in practice patterns of post-PE management both within and between countries. This project aims to develop, test and implement a structured follow-up care model for patients with PE (The Attend-PE model). This project is a pre-post intervention study and will estimate the effectiveness of implementing the structured follow-up care model on a national level.
