Child maltreatment and onset of emergency department presentations for suicide-related behaviors
Bibliographic record
Abstract
OBJECTIVES: To determine whether the rates of a first presentation to the emergency department (ED) for suicide-related behavior (SRB) are higher among children/youth permanently removed from their parental home because of substantiated maltreatment than their peers. To describe the health care settings accessed by these children/youth before a first SRB presentation to help design preventive interventions. METHODS: A population-based (retrospective) cohort of 12-17-year-olds in Ontario, Canada was established. Children/youth removed from their parental home because of the above noted maltreatment (n=4683) and their population-based peers (n=1,034,546) were individually linked to administrative health care records over time to ascertain health service use and subsequent ED presentations for SRB during follow-up. Person-time incidence rates were calculated and Cox regression models used to estimate adjusted hazard ratios (HR) and corresponding 95% confidence intervals (CI). RESULTS: After controlling for demographic characteristics and prior health service use, maltreated children/youth were about five times more likely to have a first ED presentation for SRB compared to their peers, in both boys (HR: 5.13, 95% CI: 3.94, 6.68) and girls (HR: 5.36, 95% CI: 4.40, 6.54). CONCLUSIONS: Children/youth permanently removed from their parental home because of substantiated child maltreatment are at an increased risk of a first presentation to the ED for SRB. The prevention of child maltreatment and its recurrence and the promotion of resilience after maltreatment has occurred are important avenues to study toward preventing ED SRB presentations in children/youth. Provider and system level linkages between care sectors may prevent the need for such presentations by providing ongoing environmental support.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
