US Mental Health-Related Emergency Department (ED) Visit Counts for Adults Aged 18 to 64 years, Overall and by DisorderThis figure includes data from January 1, 2019, through August 14, 2021. Shaded areas of the graph depict time periods included in the analytic index or comparison periods, which are as follows: the prepandemic comparison periods (February 10-March 9, 2019, and July 14-August 10, 2019), the COVID-19 case peak comparison period (December 27, 2020-January 23, 2021), the period immediately after a COVID-19 case peak index period (February 14-March 13, 2021), a COVID-19 pandemic comparison period with low circulation of the Delta variant, called the pre-Delta period (April 18-May 15, 2021), and a COVID-19 pandemic index period with high circulation of the Delta variant, called the Delta period (July 18-August 14, 2021). To accommodate differences in counts of all mental health-related visits and specific disorders, results for high-prevalence (A), medium-prevalence (B), and low-prevalence (C) disorders are presented.
