Regulated language held steady. Clinical governance, patient safety obligations, and pharmaceutical frameworks produce distinctive patterns that AI tools struggle to replicate, creating natural resistance to drift.
Three findings from the Healthcare sector corpus. Each carries statistical evidence from the full PRISM™ analysis.
Jargon load second-highest after Finance. Clinical terminology resists simplification. The language of pharmacovigilance, adverse event reporting, and clinical trials is structurally distinct.
Cultural markers declined moderately, roughly half the rate of commercial sectors. National health system references and regional clinical traditions partially held.
Citation density remained almost stable. Regulatory requirements to cite evidence, reference clinical guidelines, and attribute findings created structural resistance.
Current PLI scores versus 2015–2019 baseline. Sorted by drift magnitude.
Current PLI score versus 2015–2019 baseline. Scores with fewer than 10 documents in the current window are excluded. ⓘ Ordering rationale

Organisations are ranked by PLI score. The confidence badge reflects the number of scored documents in the current window: High (≥ 30 documents), Medium (10–29), Low (fewer than 10). Low-confidence scores are included in the ranking and should be read alongside the document count.
