![]() Among injury-related ED visits, sprains and strains were the most frequent first-listed diagnoses in 2014 (5.8 million visits). The rate of injury-related ED visits decreased 12.9 percent from 2006 to 2014.Diagnoses involving abdominal pain were the most frequent medical diagnoses for ED visits in 2014 (6.0 million visits). The rate of ED visits for medical conditions increased 11.7 percent from 2006 to 2014.The number of ED visits covered by Medicaid and Medicare increased between 20 (66.4 percent and 28.5 percent, respectively), whereas the number of ED visits covered by private insurance decreased (10.1 percent).The number of ED visits increased 14.8 percent from 2006 to 2014.There were 137.8 million emergency department (ED) visits in 2014, with a rate of 432 per 1,000 population.Table 1 presents the distribution and rate of ED visits in 20, overall and by select characteristics. Relative differences in estimates of 10 percent or greater are noted in the text. The number of ED visits for the most frequent first-listed diagnoses seen in the ED and the diagnoses with the greatest percent change between 20 are compared. Trends in ED visits by expected payer from 2006 to 2014 are presented along with changes in the distribution of expected payer by type of first-listed diagnosis of the visit. The first-listed diagnosis for ED visits was grouped into four categories-injury, medical, mental health/substance abuse, and maternal/neonatal. Population-based ED visit rates in 20 are provided by patient characteristics, whether the ED visit resulted in admission to the same hospital or resulted in the patient being treated and released, and the type of first-listed diagnosis for the ED visit. This Healthcare Cost and Utilization Project (HCUP) Statistical Brief presents information on ED visits between 20. 7 ED utilization may also vary over time because of rapid changes in the healthcare system, insurance coverage, and access to care, although evidence has been mixed. The diversity of clinical reasons for presenting to the ED-and their associated urgency- results in variation in the mix of ED visits based on factors such as geographic location and community socioeconomic characteristics. 6 EDs also provide care for nonurgent situations, serving as an alternative to primary care. The ED is a healthcare setting where patients receive care for a variety of circumstances, including life-threatening emergencies, acute illness and injury, and complications associated with chronic conditions. 3 ED visits have outpaced population growth since at least 1993, 4 but the trend has not been uniform across conditions or patient characteristics. Over half of the 35.4 million annual inpatient admissions in the United States begin in the emergency department (ED), 1 yet more than 5 times as many ED visits are treated and released 2 from the ED as are admitted to the same hospital.
