Abstract
In the early 1960s, some medical centers began to develop intensive care unit (ICU) information systems to monitor critically ill patients. These used a combination of devices to obtain measurements and derive variables. One generated a severity index to guide treatment and compute the probability of survival; another saved data to use in analysis and educational simulations. Studies of the clinical effectiveness of such systems were mixed, despite findings that variations in hospital death rates were associated with variations in care processes. While few hospitals had emergency department (ED) subsystems installed by the end of the 1980s, some participated in community emergency medical systems that routed patients to hospitals for treatment. Despite progress in intervening years, recent studies find that both settings face continued challenges. The data-intensive ICU faces interoperability issues arising from incompatible piece of monitoring equipment. For the ED, exchange of patient information from other settings remains difficult and evidence as to the impact of health information technology remains limited.
