Few studies have analyzed suicide deaths and attempts occurring outside inpatient units on other hospital locations. We aimed to quantify and analyze suicide deaths and attempts occurring on Department of Veterans Affairs medical center outpatient clinic areas, common areas, and hospital grounds including parking lots to determine whether a relationship with access to mental health care exists and to elucidate potential mitigation strategies. We conducted a retrospective review of patient safety report (n = 3,186), root cause analysis (n = 234), and issue brief (n = 2,064) national databases between January 1, 2015, and December 31, 2018, to identify occurrences of suicides and attempts. Correlation between mental health access times and hospital-specific rates of suicides and attempts was assessed. Qualitative analyses of root causes and mitigation strategies were conducted. Of 192 reports meeting our location criteria, 42 suicides or attempts occurred in outpatient clinic areas, 39 in common spaces, and 111 on outdoor facility areas. Forty-four reports (23%) pertained to suicides, and 148 (77%) pertained to attempts. The predominate methods were death by firearms (64%) and attempt by drug overdose (38%). We identified a weak yet significant relationship between mental health access times for established patients and rates of on-campus suicides and attempts (r = 0.279, P = 0.0013). Clinical changes including environmental assessments and interventions, staff training on identifying suicide risk characteristics, policy changes toward improving contraband search techniques, and medications risk assessment, as well as timely access to care may be effective mitigation strategies toward preventing suicides of this nature.
