The ultimate aim of this study is to pilot test a discharge tool which has the potential to reduce unnecessary visits to the Emergency Department (ED), reduce healthcare expenditure in the ED, as well as streamline and enhance the quality of care delivered to ED patients.
The ED is an important and frequently used setting of care for a large part of the U.S. population. In 2006, there were nearly 120 million ED visits in the U.S., of which only 15.5 million (14.7%) resulted in admission to the hospital or transfer to another hospital. Thus the majority ED visits result in discharge to home. Patients discharged from the ED face significant risk for adverse outcomes, with between 3-5 patients per 100,000 visits experiencing an unexpected death following discharge from the ED. Additionally, a sizable minority of patients return to the ED frequently. Published studies estimate that 4.5% to 8% of patients revisit the ED 4 or more times per year, accounting for 21% to 28% of all ED visits. Internal data from John Hopkins Hospital, AHRQ's contractor for this pilot test, supports these findings with 7% of their patients accounting for 26% of visits to the Johns Hopkins Hospital ED in 2011.
Patients who revisit the ED contribute to overcrowding, unnecessary delays in care, dissatisfaction, and avoidable patient harm. ED revisits are also an important contributor to rising health care costs, as ED care is estimated to cost two to five times as much as the same treatment delivered by a primary care physician. Thus it is estimated that eliminating revisits and inappropriate use of EDs could reduce health care spending as much as $32 billion each year. Overall, an effective and efficient ED discharge process would improve the quality of patient care in the ED as well as reduce healthcare costs.
To respond to the challenges faced by our nation's EDs and the patients they serve, AHRQ will develop and pilot test a tool to improve the ED discharge process.
