Email: [email protected] Purpose: screening tool of older people's prescriptions (STOPP) and screening tool to alert to right treatment (START) cri-teria were first published in 2008. Due to an expanding therapeutics evidence base, updating of the criteria was required.
Methods: we reviewed the 2008 STOPP/START criteria to add new evidence-based criteria and remove any obsolete criteria.
A thorough literature review was performed to reassess the evidence base of the 2008 criteria and the proposed new criteria.
Nineteen experts from 13 European countries reviewed a new draft of STOPP & START criteria including proposed new cri-teria. These experts were also asked to propose additional criteria they considered important to include in the revised STOPP& START criteria and to highlight any criteria from the 2008 list they considered less important or lacking an evidence base.
The revised list of criteria was then validated using the Delphi consensus methodology.
Results: the expert panel agreed a final list of 114 criteria after two Delphi validation rounds, i.e. 80 STOPP criteria and 34START criteria. This represents an overall 31% increase in STOPP/START criteria compared with version 1. Several newSTOPP categories were created in version 2, namely antiplatelet/anticoagulant drugs, drugs affecting, or affected by, renalfunction and drugs that increase anticholinergic burden; new START categories include urogenital system drugs, analgesicsand vaccines.
Conclusion: STOPP/START version 2 criteria have been expanded and updated for the purpose of minimizing inappropriateprescribing in older people. These criteria are based on an up-to-date literature review and consensus validation among aEuropean panel of experts.
