A same-time medication association cannot determine whether exposure preceded frailty.
The study evaluated 923 community-pharmacy outpatients aged sixty-five to seventy-four. Higher medication counts and several potentially inappropriate medication categories, including benzodiazepines, were associated with higher frailty scores. Relationships differed across age strata.
The regional cross-sectional sample did not establish that reducing one drug would reverse frailty. Illness severity can increase both prescribing and vulnerability. Screening-defined inappropriate use differs from an observed adverse reaction, and subgroup patterns may be imprecise.
For a functional assessment, reconstruct baseline mobility, nutrition, comorbidities and medication changes. Do not treat the frailty score as a benzodiazepine toxicity test. The study supports medication review in vulnerable patients while leaving individual causation and reversibility unresolved.
