Combining Machine Learning Models and Screening to Enhance Suicide Risk Identification for American Indian Patients: Retrospective Cohort Study
To evaluate the integration of a machine learning (ML) suicide risk model with the ASQ screening tool in emergency department (ED) visits among American Indian populations, addressing the urgent need for effective prevention strategies.
Key Findings:
The ML model achieved an AUROC of 0.83 for predicting suicide attempts or deaths within 90 days, indicating strong predictive capability.
Parallel testing strategies identified more at-risk individuals compared to screening alone, enhancing early intervention opportunities.
Serial testing strategies reduced false positives but risked missing some at-risk individuals, highlighting a trade-off in risk assessment.
Interpretation:
Integrating ML models with existing screening practices can enhance suicide risk identification in American Indian populations, potentially improving prevention efforts, though challenges in integration must be addressed.
Limitations:
The study is retrospective and may not account for all variables influencing suicide risk, which could affect the reliability of the findings.
Limited generalizability to other populations outside American Indian communities may restrict the applicability of the results.
Conclusion:
Combining ML models with traditional screening tools may optimize suicide risk assessment and improve clinical workflows in emergency settings, emphasizing the need for culturally tailored approaches.
