FORENSIC TOXICOLOGY

A palliative-care cohort found an association between benzodiazepine treatment and catheterization, but catheter use had several clinical drivers.

What the source reports

Among 104 inpatients across two sites, 43 underwent catheterization. Retention was the most common indication. Benzodiazepine and antipsychotic use, poor functional status, and longer admission were associated with catheterization. Most catheterized patients had been admitted for terminal care.

Limits of the evidence

The study was observational and relied on univariate comparisons. Medication may mark agitation, severity, or end-of-life care rather than independently cause urinary difficulty. Documentation around bladder assessment was incomplete, and catheterization can appropriately improve comfort.

Implications for forensic review

For a medication-related retention opinion, reconstruct urinary symptoms, bladder findings, drug timing, functional decline, and competing causes. The association is a prompt for investigation. It does not show that every catheter placed during benzodiazepine treatment represents an adverse drug effect or improper care.
