Studies still report a high prevalence of inappropriate prescribing in older people. To reduce the problem of underprescribing and overprescribing in this population, explicit drug optimisation tools like Screening Tool of Older Persons' potentially inappropriate Prescriptions/Screening Tool to Alert to Right Treatment (STOPP/START) have been developed. The aim of this study was to evaluate the clinical applicability of STOPP/START criteria in daily patient care by assessing the clarity of singular criteria. DESIGN Quality appraisal study. METHODS For each of the 114 STOPP/START criteria V.2, elements describing the action (what/how to do), condition (when to do) and explanation (why to do) were identified. Next, the clarity of these three elements was quantified on a 7-point Likert scale using tools provided by the Appraisal of Guidelines for Research and Evaluation (AGREE) Consortium. PRIMARY AND SECONDARY OUTCOMES The primary oclarity of clinical practice guidelines on a language level and therefore enhance clinical applicability. © Author(s) (or their employer(s)) 2020.
