Key Takeaways
Extended Takeaways
- This analysis suggests that structured encounter counts may miss clinically meaningful differences: the authors previously found similar psychotherapy frequency across groups, but unstructured note review identified distinct content patterns between risk-matched cases and controls.
- The topic model was deliberately tuned for discrimination rather than maximum granularity, with 5 topics selected because larger models had marginally higher coherence but substantial overlap, and a 20% topic-proportion threshold chosen because it yielded the greatest number of significant case-control differences across risk tiers.
- At higher suicide risk tiers, note content shifted away from Risk, Treatment Planning, Evaluation, and Medication themes and toward Psychosocial themes, indicating that psychotherapy documentation in the highest-risk patients may be dominated more by inpatient routines, group interventions, and care progress than by collaborative planning or medication-related discussion.
- The Medication topic was the most consistent differentiator, with controls showing significantly higher proportions of medication-related notes at every risk tier; clinicians may want to consider whether medication management and documentation become less consistent in patients who later die by suicide.
- The Psychosocial topic became less useful for separating cases from controls as risk increased, with no significant difference between high-risk cases and controls, suggesting that group-based and inpatient-oriented care may homogenize documentation patterns in the highest-risk subgroup.
- Interpretation should stay at the level of care patterns rather than treatment efficacy: the study could not distinguish EBP from non-EBP psychotherapy, could not control for specific intervention formats, and used ICD-based PTSD identification and VA-only records, so the findings inform service characterization more than causal conclusions about what prevents suicide.
