Service utilization in 1896 and 1996: morbidity and mortality data from North Wales
Bibliographic record
Abstract
The 1896 and 1996 populations of North-West Wales are similar in number, ethnic and social mix and rurality, enabling a study of the comparative prevalence of service utilization, as well as the morbidity and mortality associated with mental illness in 1894-96 and 1996. The 1996 data reveal a 15 times greater prevalence of admissions for all diagnoses, and three times greater prevalence of admissions by detention, compared with 1896. Patients now spend more time in a service bed than they did 100 years ago. Death as a direct consequence of mental illness is commoner now than 100 years ago. There is therefore a major disjunction between the rhetoric and the reality of mental health service utilization. General factors related to changing health care and expectations and specific factors linked to the mental health appear to have led to an increased rate of service utilization in the modern period.

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.
