Abstract

fetched live from OpenAlex

BACKGROUND: Overdose is frequently categorized dichotomously: an inadvertent therapeutic or recreational misadventure versus a deliberate overdose for self-injurious or suicidal purposes. Categorizing overdoses based on this dichotomy of intention is fraught with methodological problems and may result in potentially inappropriate and/or divergent care pathways. OVERDOSE-RELATED INTENT LIES ALONG A CONTINUUM: Suicidality can rapidly shift in magnitude and frequency at different points in time. A patient's overdose may reflect varying degrees of desire to die, ambivalence about living, disregard for risk, or pleasure-seeking. Careful assessment of overdose-related cognitions is warranted in all overdose patients. THE CLINICAL INTERVIEW IS KEY TO UNDERSTANDING AN OVERDOSE: There is an irreducibly subjective character to an overdose such that a collaborative understanding of an overdose episode can only be discovered by spending time in dialogue with the patient. At the same time, the objective risk factors for and circumstances of the overdose need to be integrated with the subjective experience for a comprehensive prevention approach. THERE CAN BE SEVERAL MOTIVATIONS UNDERLYING AN OVERDOSE: Some overdoses might be wholly inadvertent or simply impulsive. However, if there is some degree of intent present, then the patient who overdosed has attempted to communicate something by means of that overdose, and this message might include something other than the desire to die. ATTENDING TO BOTH THE SUBJECTIVE AND OBJECTIVE PERSPECTIVES OF AN OVERDOSE CAN ASSIST IN IDENTIFYING MODIFIABLE RISK FACTORS: Overdose-related intent and motivation may be targeted with treatment plans to reduce elevated risk states. Some patient-specific overdose risk factors are modifiable, such as managing mental health and other psychosocial issues, reducing access to lethal means, and promoting safe prescribing and medication administration practices. Other risk factors are either unmodifiable (e.g., personal history of overdose) or involve public health systems. CONCLUSIONS: Overdose-whether involving medications, illicit substances, hazardous chemicals, or otherwise-can be conceptualized as a single behavioral episode with variable intentionality, personal motivations, and risk factors. Clinical/medical toxicologists are uniquely positioned to contribute to personalized risk reduction post-overdose.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
