Background/Objectives
Depression, suicide ideation (SI) and suicide attempts (SA) are common among older adults, representing serious public health problems. Individuals with multiple comorbidities and frequent contact with hospital–based emergency departments (ED) may have elevated – but unrecognized – risk. To inform future interventions, we sought to estimate the prevalence of self-harm/SI/SA among older ED patients, including differences by age group, sex, and race/ethnicity.
Design
Quasi-experimental, multi-phase, 8-center study with prospective review of consecutive patient charts during enrollment shifts (November 2011–December 2014).
Setting
8 EDs located in 7 states, all with protocols for nurses to screen every patient for suicide risk (“universal screening”).
Participants
Adult (≥18 years) registered ED patients.
Measurements
Patient demographics, documented screening for self-harm/SI/SA, positive self-harm/SI/SA among those with screening performed.
Results
Among a total of 142,534 patient visits, 23.3% were by patients aged ≥60 years. Documented screening for self-harm/SI/SA declined with age, from approximately 81% in younger age groups to a low of 68% among those aged ≥85 years. The prevalence of positive screens for self-harm/SI/SA also declined with age, with peaks among young and middle-aged adults (9.0%) and a nadir among patients aged ≥75 years (1.2%).
Conclusion
Documented screening for suicide risk declined with patient age in this large sample of ED patients. Although the explanation for this finding is unclear, we hypothesize that at least part of the decline is related to increasing rates of altered mentation or other patient-level barriers to screening in the older population. Our findings support the need for more detailed examination of the best methods for identifying – and treating – suicide risk among older adults.
