A multicenter study associated potentially inappropriate medication exposure with hospitalization, but its overall estimate was not a benzodiazepine-specific effect.
What the source reports
The prospective cohort included 1,700 older adults with chronic disease across five hospitals. Screening used the study’s specified Beers criteria. Benzodiazepine use and benzodiazepine-opioid co-use appeared among factors associated with flagged prescribing, while the hospitalization analysis concerned the broader PIM exposure category.
Limits and uncertainty
An exposure used within a prescribing-quality definition can also appear as a predictor of that definition, which requires careful interpretation. Observational adjustment cannot eliminate differences in illness or care. A broad PIM association does not isolate the effect of one class.
Implications for forensic review
An expert should keep each model’s outcome and exposure visible. It would be misleading to present the overall hospitalization odds ratio as the effect of benzodiazepines alone. For a patient, assess the actual regimen, comorbidity, indication, and admission cause before making a drug-specific conclusion.
