A dispensing-based long-term-use definition should not be silently converted into continuous ingestion or a dependence diagnosis.
What the supplied source reports
The retrospective primary-care cohort included 100,638 people with a new benzodiazepine prescription. Long-term use was defined through repeated dispensing within three months. Under the study definitions, 27.1% were classified as long-term users at three months and 14.5% at six months. Age, previous exposure and several care characteristics were associated with continuation.
Limits of the evidence
Filled prescriptions may not be taken. Services outside the Catalan public system were not fully captured, and observational predictors do not establish causal effects of a visit type or clinician characteristic. The term new prescription also needs the study’s exposure-history context.
Implications for forensic interpretation
For interpreting a medication history, distinguish initiation, dispensing, administration and dependence. Repeated fills identify an opportunity for review but do not independently establish tolerance, withdrawal or impairment. The study’s operational definition is essential when comparing its percentages with another dataset or an individual patient’s course.
