In the ED or UCC cohort, categories are not mutually exclusive. For example, because unique individuals in the ED could have multiple encounters, they could have been counted in multiple categories if screening results differed during these encounters. In such cases, they would be counted only once in each category.
A total of 22 569 unique people in the ED or UCC cohort had a positive item 9 response and negative item 9 response on 2 separate encounters.
In the AC cohort, 1691 of those with no C-SSRS Screener result went from a positive item 9 response to a Comprehensive Suicide Risk Evaluation; in the ED or UCC cohort, 2346 of those with no C-SSRS Screener result went from a positive item 9 response to a Comprehensive Suicide Risk Evaluation.
A total of 2110 unique people in the ED or UCC cohort had a positive C-SSRS Screener result and a negative C-SSRS Screener result on 2 separate encounters.
