OBJECTIVES: Suicide is a preventable US health crisis, accounting for >40,000 deaths/year. Hospitalization is a common intervention for patients diagnosed with suicidal ideation (SI) or suicide attempt (SA). We evaluated the demographic, clinical, and health resource utilization profile of patients admitted with SI/SA to understand their unmet needs.

METHODS: Patients admitted from 2010-2014 with a diagnosis of SI or SA were identified in the Premier Perspective® hospital database. Descriptive statistics were generated for different admission measures.

RESULTS: There were 372,298 SI (50.0% female) and 85,551 SA admissions (61.6% female). Mean age was similar (SI=39.1±17.5; SA=40.7±16.5). Psychiatric comorbidities included: depression (SI=75.0%; SA=79.6%), major depressive disorder (MDD) (SI=34.1%; SA=38.4%), substance abuse (SI=57.8%; SA=68.7%), bipolar disorder (SI=30.4%; SA=30.6%) and anxiety (SI=25.9%; SA=27.7%). Commonly used psychoactive medications included: lorazepam (SI=35.9%; SA=38.7%), trazodone (SI=22.3%; SA=16.4%), ondansetron (SI=14.3%; SA=33.1%) and quetiapine (SI=15.6%; SA=12.3%). Mean length of stay (LOS) was similar (SI=5.1 ± 6.3 days; SA=4.6 ± 5.3 days). More SA patients were discharged dead (SI=0.1%; SA=0.8%), received ICU care (SI=5.6%; SA=46.3%), or discharged to psychiatric facilities (SI=13.7%; SA=37.0%). Of all SI/SA admissions, 37% (n=136,820) and 45% (n=38,511), respectively, had follow-up data and were assessed for readmission measures (for all diagnoses) including: 30-day readmit rate (SI=45.8%; SA=75.6%), mean days to readmission (SI=47.2 ± 46.0; SA=25.7 ± 38.6) and mean LOS (SI=7.0±6.9; SA=6.3±6.0).

CONCLUSIONS: Patients with SI/SA have complex medical histories; many are diagnosed with MDD and therefore at higher risk for suicide, requiring intensive long-term intervention. Evaluating different sub-groups of these patients is warranted.
