- Figure 1:
Emergency department visits and hospitalizations related to mental health and substance use disorders per 1000 population aged 10 to 105 years. Joinpoint regression analysis identified a statistically significant change in slope at July 2020 (*p ≤ 0.05) among overall and male visits to emergency departments. We observed a decrease in hospitalizations related to mental health and substance use disorders for both sexes in April 2020. Joinpoint regression analysis did not yield any significant changes in slope. Note: ED = emergency department.
- Figure 2:
Emergency department visits for intentional self-injury, as well as admission rates and ICU or death rates per 10 000 population aged 10 to 105 years. We observed a decrease in emergency department visits for intentional self-injury in April 2020 among those who were admitted following self-injury and among those who were transferred to the ICU or died in the emergency department. Joinpoint regression analysis identified a statistically significant change in slope in July 2020 (*p ≤ 0.05) among those who were transferred to the ICU or died in the emergency department. Note: ED = emergency department, ICU = intensive care unit.
- Figure 3:
(A) Emergency department visits and (B) hospitalizations related to mental health and substance use disorders per 1000 population aged 10 to 105 years, by age. For emergency department visits, joinpoint regression analysis identified statistically significant changes in slope in April 2020 (*p ≤ 0.05) for those aged 10 to 17 years and in July 2020 for those aged 18 to 21 years and those aged 25 to 105 years. For hospitalizations, we observed a decrease among all age groups in April 2020. Joinpoint regression analysis did not yield any significant changes in slope.
- Figure 4:
(A) Emergency department visits and (B) hospitalizations related to mental health and substance use disorders per 1000 population aged 10 to 105 years, by diagnosis. Joinpoint regression analysis identified statistically significant changes in slope in July 2020 (*p ≤ 0.05) in emergency department visits for anxiety, schizophrenia spectrum and other psychotic disorders, and trauma and stressor-related disorders. We observed a decrease in hospitalizations across all diagnostic categories in April 2020, but joinpoint regression analysis did not yield any significant changes in slope.
