Home Delivery: Transfusion Services When and Where They Are Needed

Home blood product transfusion has been utilized around the world in various forms over the past few decades. There is current interest in decentralizing hospital care to improve patient independence and convenience, minimize cost to the health service, and to prevent nosocomial infection, especially with the recent COVID-19 pandemic. The transition to "hospital in the home" is occurring across the healthcare sector driven by aims to improve patient outcomes and patient satisfaction, capacity pressures in the acute care sector, and most recently due to concerns regarding infectious disease transmission in hospital settings. This review explores the published literature on home red cell and platelet transfusions, and where the literature is limited, also considered data from subcutaneous immunoglobulin studies. Current published experience on red cell and platelet transfusion at home has identified benefits to the patient and health service, with further studies needed to quantify improvement in quality of life and health-related outcomes. Safety concerns may be a perceived barrier to implementation of home transfusion, however current published data suggests serious adverse reactions are rare. Cost-effectiveness data for home transfusion are very limited and a key area for future research. Home transfusion has the potential to benefit from newer technologies, such as portable/remote monitoring and electronic patient identifiers.
