Abstract

fetched live from OpenAlex

ABSTRACT Using electronic medical record (EMR) data collected from psychiatric inpatient admissions, the objective of this study was to identify sex differences in risk factors for presence of suicide plans and/or attempts within the 30 days preceding hospital admission. Resident Assessment Instrument for Mental Health (RAI-MH) intake data were obtained for patients admitted to a Canadian tertiary-care hospital deemed a ‘threat or danger to self’ during a ten-year period (2008-2018). Data was extracted for individuals categorized into three groups: non-suicidal (N=568), presence of suicide plan (N=178), and presence of suspected suicide attempt (N=124) in the 30 days prior to hospital admission. A multivariate logistic regression revealed that younger age (odds ratio=0.97), female sex (OR=1.56), disrupted family relationships (OR=1.54), recent stressors (OR=1.59), participation in social activities (OR=1.54), having no confidant (OR=1.55), and diagnosis of depressive disorder (OR=5.54) increased the odds of suicide plan and/or attempt in the 30 days prior to hospital admission. Stratifying the regression model by sex highlighted different risk factors for suicide plan and attempt specific to males and females. EMR-derived findings highlight psychosocial and clinical determinants associated with suicide plan or attempt prior to psychiatric admission that differ according to sex.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
