Abstract

fetched live from OpenAlex

Abstract Background Sedative medications (benzodiazepines and Z‐drugs) are used to treat responsive behaviours in those with dementia despite association with adverse drug events and accepted status as potentially inappropriate medications. The objective of this study was to complete a sex‐based analysis of sedative use in a cohort of older adults with dementia in Nova Scotia, Canada. Method We examined sedative use in a cohort of adults aged 65 years and older with dementia in Nova Scotia, Canada. Prescription data was examined from April 1, 2010 to March 31, 2015. Concordance with prescribing guidelines was compared for men and women using descriptive statistics and unadjusted odds ratios. Result Of the 30,703 older adults with dementia in the cohort 11,647 (37.9%) received at least one prescription for a sedative. Women were more likely to receive a benzodiazepine (OR 1.44; 95% CI [1.36‐1.53]) or a Z‐drug (OR 1.10; 95% CI [1.01‐1.19]). Lorazepam was the most commonly prescribed sedative (52% of sedative users). Zopiclone was the second most commonly prescribed (27% of sedative users). Sedative use (37.9% of cohort) which is potentially inappropriate was almost two times greater than cholinesterase inhibitor use (19.3% of cohort) which is potentially appropriate for older adults with dementia. Conclusion Among older adults with dementia, sedatives are more commonly prescribed than cholinesterase inhibitors. Sedatives are more often used by women, suggesting that targeted interventions toward reducing sedative use in women is needed. This pattern of sedative use is not in accordance with prescribing guidelines for older adults with dementia.

Not 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.
