Descriptive statistics for all Patient Health Questionnaires (PHQ9) completed in psychiatry and addiction medicine in 2019 (n = 70,036) that indicated* a patient needed further assessment with a Columbia Suicide Severity Rating Scale (C-SSRS). Data are presented in aggregate for 5 Kaiser Permanente (KP) regions. This indication was a response of “some/most/almost all days in the last two weeks” to the 9th item of the PHQ9, “How often in the last two weeks have you had thoughts that you would be better off dead, or of hurting yourself in some way?” Data are presented as sample size and percentage. The rates of C-SSRS administration by KP region are shown in Figure 1.
