PEN-Plus Strategies II: Decentralizing and Integrating Postoperative Management and Anticoagulation

Countries building sustainable, cardiac surgical care must ensure that the local health system has the capacity to support routine postoperative follow-up and generate the infrastructure required to provide timely diagnosis and management of common postoperative complications. Following valvular cardiac surgery, most patients will need management of residual symptoms of heart failure, adjustment and monitor of anticoagulation, administration of lifelong penicillin prophylaxis and guidance on how to navigate family planning. Anticoagulation has historically been seen as an insurmountable challenge in the rural poor; however, in this chapter, we present the PEN-Plus model for decentralized postoperative management—and provide insight into how its application can guide the way forward to support sustainable post-surgical capacity and appropriate patient follow-up in resource-constrained settings. Warfarin, for example, is a standard anticoagulant prescribed following most routine cardiovascular procedures, and its management requires careful consideration in under-resourced settings. Given its teratogenicity and associated untoward effects, if not managed properly, warfarin can present life threatening complications. As such, district hospitals must be equipped with the capacity to diagnose anticipated complications, to treat mild cases and to refer more severe cases of bleeding, valve thrombosis, or thromboembolic events toward tertiary levels of care in a timely and efficient manner. Patients must be counselled on the attendant risks of anticoagulation, and be provided education on how to maintain a consistent diet. Health systems must ensure that district hospitals have a reliable supply of both warfarin and INR testing supplies. Providers must be trained to diagnose and manage common ongoing complications including endocarditis, sternal wound infection and dehiscence, pericardial and pleural effusions, atrial fibrillation, valve thrombosis, valve dehiscence and hemolytic anemia. Furthermore, health systems need to set up comprehensive support systems for patients, including cardiac rehabilitation, nutritional, socioeconomic and mental health supports.
