Validation and Adjustment of the OxSATS Suicide Risk Model Following Self-Harm in an English Context
Clinical Scorecard: Validation and Adjustment of the OxSATS Suicide Risk Model Following Self-Harm in an English Context
At a Glance
Category Detail
Condition Suicide Risk Following Self-Harm Key Mechanisms External validation and recalibration of the OxSATS model to predict suicide risk. Target Population Individuals aged ≥10 years presenting to emergency departments for self-harm. Care Setting Emergency departments and secondary mental health services.
Key Highlights
OxSATS demonstrated good discrimination with a c-index of 0.73. Recalibration improved model calibration with an O:E of 1.00. The study is the first external validation of OxSATS in an English clinical setting. Initial calibration showed overprediction of suicide risk due to lower baseline event rates. Structured risk assessment tools can aid in recognizing individuals needing further risk management. Guideline-Based Recommendations
Diagnosis
Utilize the OxSATS model for estimating suicide risk following self-harm. Management
Consider structured risk assessment tools for comprehensive clinical assessments. Monitoring & Follow-up
Implement closer monitoring and follow-up for individuals identified at high risk. Risks
Be aware of the potential for overprediction in different clinical settings. Patient & Prescribing Data
Individuals presenting to hospitals after self-harm.
Structured assessments may facilitate better resource allocation and follow-up care.
Clinical Best Practices
Conduct external validation of risk models before implementation in new settings. Perform sensitivity analyses to address missing predictors. Recalibrate models as necessary to ensure accurate risk predictions. Related Resources & Content
