Psychiatric bed utilization: 1896 and 1996 compared
Bibliographic record
Abstract
BACKGROUND: 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 incidence and prevalence of service utilization over the course of a century. METHODS: We collected records on all psychiatric admissions from North-West Wales in 1894-1896 and 1996. These were assessed and diagnosed by the responsible sector area consultant. RESULTS: The data reveal substantially more patients admitted for all diagnoses in 1996. even when comparisons are restricted to detained patients. The incidence of hospitalization by detention for schizophrenia is slightly lower 1996 than in 1896 but the incidence of hospitalization is higher now than in 1996. The incidence of hospitalization by detention for non-affective disorder psychoses is the same in both 1896 and 1996 but there is a doubling of incidence of hospitalization. The incidence of hospitalization for bipolar disorders is similar in the two periods. Modern mental health services admit large numbers of personality disordered patients, where none were admitted 100 years ago. CONCLUSIONS: Factors general to changing health care and expectations and others specific to mental health would appear to have led to the increase in rates of admissions observed 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.
