Introduction: Major depressive disorder (MDD) and suicidal ideation/behavior, both incur substantial mental health resource utilization (MHRU) burden, yet little is known of the burden of suicidal ideation/ behavior within the MDD population and how this burden varies by demographic factors.
Methods: Cross-sectional study based on 2017 NSDUH survey data comparing MHRU among 3 cohorts: 1) MDD with suicidal ideation (MDD+SI) (reported major depressive episode and serious thoughts, plan or attempt to kill self), 2) MDD without SI and 3) neither MDD nor SI. Design-adjusted Chi-Square test was used to test associations.
Results: The MDD+SI cohort showed significantly higher MHRU than MDD without SI and those with neither illness : inpatient (10.4% v 2.2% and 0.6%, respectively; p<0.001; p<0.001); outpatient (46.8% v 33.5% and 4.7%; p<0.001; p<0.001); prescriptions (57.7% v 45.0% and 8.6%; p<0.001; p<0.001); or “any mental health treatment” (65.8% v 53.1% and 10.8%; p<0.001; p<0.001). Among MDD+SI, young adults (18-25 years) were less likely than ≥26 year-olds to have outpatient visits (40.1% v 50.4%; p=0.009), prescriptions (46.3% v 63.8%; p<0.001) or “any mental health treatment” (57.9% v 70.0%; p=0.001); and men were less likely than women to have outpatient visits (39.1% vs 51.6%; p=0.01); prescriptions (47.3% v 64.1%; p<0.001) or “any mental health treatment” (55.2% v 72.4%; p<0.001).
Conclusions: Patients with MDD+SI have significantly higher MHRU than those with MDD without SI and those with neither illness yet a third report not receiving mental health treatment. Findings also suggest potential age and gender disparities in MHRU that warrant attention.
