Abstract Purpose STOPP/START is a physiological systems-based explicit set of criteria that attempts to define the clinically important prescribing problems relating potentially inappropriate medications (PIMs–STOPP criteria) and potential omissions (PPOs–START criteria). The previous two versions were published in 2008 2015. present study describes revised updated third version criteria. Methods A detailed system-by-system review literature from April 2014 March 2022 was undertaken with aim...

Abstract Background Healthcare professionals are often reluctant to deprescribe fall-risk-increasing drugs (FRIDs). Lack of knowledge and skills form a significant barrier furthermore, there is no consensus on which medications considered as FRIDs despite several systematic reviews. To support clinicians in the management facilitate deprescribing process, STOPPFall (Screening Tool Older Persons Prescriptions older adults with high fall risk) tool were developed by European expert group....

Multi-morbidity and polypharmacy increase the risk of non-trivial adverse drug reactions (ADRs) in older people during hospitalization. Despite this, there are no established interventions for hospital-acquired ADR prevention.We undertook a pragmatic, multi-national, parallel arm prospective randomized open-label, blinded endpoint (PROBE) controlled trial enrolling patients at six European medical centres. We 1,537 surgical with multi-morbidity on admission 1:1 ratio to SENATOR...

The aging of our societies leads to a higher prevalence multimorbidity and therefore polypharmacy, which often results in inappropriate drug treatment. To address this issue, numerous listing approaches, such as the Fit fOR Aged (FORTA) list have been developed. FORTA's positive impact on quality medications relevant clinical outcomes has shown. Based new emerging evidence experiences with existing FORTA lists, we aimed update lists several European countries/regions.Two-step Delphi...

Falls are a major public health concern in the older population, and certain medication classes significant risk factor for falls. However, knowledge is lacking among both physicians people, including caregivers, concerning role of as factor. In present statement, European Geriatric Medicine Society (EuGMS) Task Finish group on fall-risk-increasing drugs (FRIDs), collaboration with EuGMS Special Interest Pharmacology Union Medical Specialists (UEMS) Section, outlines its position regarding...

Abstract Inappropriate polypharmacy is highly prevalent among older adults and presents a significant healthcare concern. Conducting medication reviews implementing deprescribing strategies in multimorbid with are an inherently complex challenging task. Recognizing this, the Special Interest Group on Pharmacology of European Geriatric Medicine Society has compiled evidence review formulated recommendations to enhance appropriate prescribing practices. The current supports need for...

Most studies on pharmacodynamic variables in vitro, including the postantibiotic effect (PAE), are performed at pH 7.4 noncationic-supplemented media, a situation which may differ significantly from true microenvironment most infected foci. We studied impact of five different levels (pH 5, 6, 7, 7.4, and 8) duration PAE, MIC, bactericidal activity. Acid was found to have general deleterious activity aminoglycosides ciprofloxacin against Escherichia coli Pseudomonas aeruginosa, with MIC being...

Abstract Background The aim of this study was to determine the prevalence preoperative polypharmacy and incidence postoperative polypharmacy/hyper-polypharmacy in surgical patients their association with adverse outcomes. Methods This a retrospective, population-based cohort among older than or equal 18 years undergoing surgery at university hospital between 2005 2018. Patients were categorized based on number medications: non-polypharmacy (fewer 5); (5–9); hyper-polypharmacy (greater 10)....

Abstract Purpose Adverse drug reactions (ADRs) are a major cause of morbidity and mortality, especially in older people. Older people with diabetes mellitus may be at high risk ADRs but this has not been well studied. This study aimed to compare severity type hospitalised, multimorbid without secondly assess the impact on rehospitalisation length stay. Methods Participants SENATOR (Software Engine for Assessment optimization non-drug Therapy peRsons) trial were assessed 12 common ‘other’...

Older women experience more adverse drug reactions (ADRs) than older men. However, the underlying basis for this sex difference is unclear. Sex (biological status) and/or gender (sociocultural constructs) influences on patterns of inappropriate prescribing in multimorbid adults may be one reason ADR difference. In secondary analysis, we examined whether incident differences could related to concurrent potentially prescribing.
