TITLE: Safety of Air Vents in Psychiatric Units in a Hospital Setting: A Review of the Clinical Evidence and Guidelines
Bibliographic record
Abstract
It is critical that the design of psychiatric facilities minimize the environmental risk factors that may impact patient safety, and in particular patient suicide. One of the goals of environmental safeguards in psychiatric facilities is to limit the means that inpatients may use to physically harm themselves. Air vents are a physical structure that may be used to cause physical harm. In particular, air vents may be used as an anchor point that could support the weight of a patient attempting to hang him or herself. This is significant since hanging is the most common method of in-patient suicide, used in up to 75 % of cases. 1-3 Air Vents could also be used as a sharp object for cutting themselves. The number of in-patient suicides in psychiatric facilities in Canada each year could not be found. In the absence of Canadian information, data from the United States are presented. The American Psychiatric Association has reported that approximately 1,500 in-patient suicides take place in the United States each year. 4 In the United States, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) requires accredited hospitals to report all suicides as sentinel events.

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.
