Purpose: screening tool of older people's prescriptions (STOPP) and screening tool to alert to right treatment (START) criteria 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 criteria. 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 34 START criteria. This represents an overall 31% increase in STOPP/START criteria compared with version 1. Several new STOPP categories were created in version 2, namely antiplatelet/anticoagulant drugs, drugs affecting, or affected by, renal function and drugs that increase anticholinergic burden; new START categories include urogenital system drugs, analgesics and vaccines.Conclusion: STOPP/START version 2 criteria have been expanded and updated for the purpose of minimizing inappropriate prescribing in older people. These criteria are based on an up-to-date literature review and consensus validation among a European panel of experts.
of older person's potentially inappropriate prescriptions, screening tool to alert doctors to the right treatment
SUMMARYWhat is known and Objective: Potentially inappropriate prescribing (PIP) has significant clinical, humanistic and economic impacts. Identifying PIP in older adults may reduce their burden of adverse drug events. Tools with explicit criteria are being developed to screen for PIP in this population. These tools vary in their ability to identify PIP in specific care settings and jurisdictions due to such factors as local prescribing practices and formularies. One promising set of screening tools are the STOPP (Screening Tool of Older Person's potentially inappropriate Prescriptions) and START (Screening Tool of Alert doctors to the Right Treatment) criteria. We conducted a systematic review of research studies that describe the application of the STOPP/START criteria and examined the evidence of the impact of STOPP/START on clinical, humanistic and economic outcomes in older adults. Methods: We performed a systematic review of studies from relevant biomedical databases and grey literature sources published from January 2007 to January 2012. We searched citation and reference lists and contacted content experts to identify additional studies. Two authors independently selected studies using a predefined protocol. We did not restrict selection to particular study designs; however, non-English studies were excluded during the selection process. Independent extraction of articles by two authors used predefined data fields. For randomized controlled trials and observational studies comparing STOPP/START to other explicit criteria, we assessed risk of bias using an adapted tool. Results and Discussion: We included 13 studies: a single randomized controlled trial and 12 observational studies. We performed a descriptive analysis as heterogeneity of study populations, interventions and study design precluded metaanalysis. All observational studies reported the prevalence of PIP; however, the application of the criteria was not consistent across all studies. Seven of the observational studies compared STOPP/ START with other explicit criteria. The STOPP/START criteria were reported to be more sensitive than the more-frequentlycited Beers criteria in six studies, but less sensitive than a set of criteria developed in Australia. The STOPP criteria identified more medications associated with adverse drug events than the 2002 version of the Beers criteria. Patients with PIP, as identified by STOPP, had an 85% increased risk of adverse drug events in one study (OR = 1Á85, 95% CI: 1Á51-2Á26; P < 0Á001). There was limited evidence that the application of STOPP/START criteria optimized prescribing. Research involving the application of STOPP/START on the impact on the quality of life was not found. The direct costs of PIP were documented in three studies from Ireland, but more extensive analyses on the economic impact or studies from other jurisdictions were not found. What is new and Conclusion: The STOPP/START c...
Application of STOPP/START criteria resulted in significant reductions in ADR incidence and medication costs in acutely ill older adults but did not affect median LOS.
This study indicated that DRPs are prevalent in older Irish hospitalized inpatients and that a specially developed SPRM intervention supported by a CDSS can improve both the appropriateness and accuracy of medication regimens of older hospitalized inpatients.
In this LTC population, STOPP criteria identified a higher percentage of PIMs and a higher prevalence of PIP than the Beers criteria. The higher prevalence of PIP determined using the STOPP criteria is of uncertain relevance, but may be because STOPP was designed and validated for use in an Irish setting.
SummaryThis study identifies a natural system in Lactococcus lactis, in which a restriction modification specificity subunit resident on a 6159 bp plasmid (pAH33) alters the specificity of a functional R/M mechanism encoded by a 20.3 kb plasmid, pAH82. The new specificity was identified after phenotypic and molecular analysis of a 26.5 kb co-integrate plasmid (pAH90), which was detected after bacteriophage challenge of the parent strain. Analysis of the regions involved in the co-integration revealed that two novel hybrid hsdS genes had been formed during the cointegration event. The HsdS chimeras had interchanged the C-and N-terminal variable domains of the parent subunits, generating two new restriction specificities. Comparison of the parent hsdS genes with other type I specificity determinants revealed that the region of the hsdS genes responsible for the co-integration event is highly conserved among lactococcal type I hsdS determinants. Thus, as hsdS determinants are widespread in the genus Lactococcus, new restriction specificities may evolve rapidly after homologous recombination between these genes. This study demonstrates that, similar to previous observations in Gram-negative bacteria, a Gram-positive bacterium can acquire novel restriction specificities naturally through domain shuffling of resident HsdS subunits.
an FI score is a potentially relevant clinical indicator for doctors to critically assess a patient's prescription for the presence of PIP and ultimately prevent ADRs, especially when used in tandem with the number of medications a patient takes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
