Association of 7-Day Follow-Up With 6-Month Suicide Mortality Following Hospitalization for Suicidal Thoughts or Behaviors Among Older Adults.

ABSTRACT

OBJECTIVE: To evaluate whether timely follow-up outpatient mental health care is associated with reduced short-term suicide risk following hospitalization for suicidal thoughts or behaviors. METHODS: Retrospective cohort analysis using 2015 Medicare data for adults aged ≥ 65 years who were hospitalized for suicidal ideation or behaviors (n = 36,557) linked with the National Death Index. Adjusted risk ratios (ARR) estimated the association between 7-day follow-up and suicide risk at 30-, 90-, and 180-days, adjusted for confounding by indication using inverse probability of treatment weights of observable covariates. RESULTS: Overall, 39.3% of patients received 7-day follow-up, which was associated with 41% higher risk of suicide within 180 days. Follow-up care was associated with higher suicide risk for Medicare Advantage enrollees, patients with no recent prior mental health care, and those admitted for suicidal behaviors. CONCLUSION: Results suggest 7-day follow-up care was not associated with lower post-discharge suicide risk. For this high-risk group, suicide-specific interventions may be needed during the critical postdischarge period.
