Background: Explicit criteria for potentially inappropriate medications (PIMs) developed for other countries are difficult to apply to a specific territory. This study aimed to update the PIM-Taiwan criteria from a qualitative review of several published PIM criteria, followed by consensus among regional experts in Taiwan. Methods: After a review of the literature, we selected four sets of published PIM criteria to construct preliminary core PIMs. The Beers criteria, Fit fOR The Aged (FORTA), and Japan criteria were used for PIMs, without consideration of chronic diseases. The Beers criteria, Screening Tool of Older Persons’ Prescriptions (STOPP) criteria, and Japan criteria were used for PIMs with respect to chronic diseases. We asked experts ( n = 24) to rate their agreement with each statement, including in the final PIM criteria, after two rounds of modified Delphi methods. The intraclass coefficient (ICC) was used to examine the reliability of the modified Delphi method. Results: Overall, two categories of PIMs were established: 131 individual drugs and 9 drugs with combinations that should generally be avoided; and 9 chronic diseases with their corresponding PIMs that have drug–disease interactions. The ICC estimates for PIMs to be avoided generally were 0.634 and 0.557 (round 1 and 2) and those for PIMs with respect to chronic diseases were 0.866 and 0.775 (round 1 and 2) of the Delphi method, respectively. Conclusions: The 2018 version of PIM-Taiwan criteria was established and several modifications were made to keep the criteria updated and relevant. Clinicians can use them to reduce polypharmacy and PIMs among older patients.

Screening Tool of Older Persons’ Prescriptions (STOPP)/Screening Tool to Alert to Right Treatment (START) criteria was first published in 2008, primarily as an alternative set of explicit criteria for potentially inappropriate medications (PIMs) to Beers criteria.

Background: Prescribing in elderly is a challenging task as they have age related physiological changes, various co-morbidities, altered pharmacological properties and higher propensity for adverse events. They are often prescribed medications which are potentially inappropriate for them, sometimes may even be unnecessary. The medicines are considered as inappropriate if the risk associated with them outweighs benefits. The objective of this study is to assess the prevalence of potentially inappropriate medications (PIM) at a tertiary care teaching hospital according to the Beers updated 2015 criteria and STOPP criteria and to compare the two criteria in detection of PIMs.Methods: A prospective observational study involving 228 elderly patients (>65years) of medicine wards was conducted from October 2015 to March 2016. Relevant information was recorded in a predesigned proforma. The use of potentially inappropriate medications is assessed using Beers updated 2015 criteria and STOPP criteria using descriptive statistics.Results: The prevalence of PIM use in the sample was 26.31% according to the 2015 Beers criteria and 14.03% using the STOPP criteria. The most prevalent PIM according to the Beers criteria were sliding scale insulin (17.54%) and long acting benzodiazepines (5.26%); according to the STOPP criteria, they were aspirin in heart failure (5.26%) and chlorpheniramine (3.07%).Conclusions: The prevalence of PIM varied when different criteria were applied. The 2015 Beers criteria identified more PIM than the STOPP criteria.

Background: The Beers Criteria and STOPP Criteria were developed to identify potentially inappropriate medications (PIMs) in the geriatric population. Utilization of STOPP Criteria PIMs have shown a significant association with presence of avoidable adverse drug events (ADEs) as compared to utilization of Beers Criteria PIMs. Objectives: The purpose of this study was to utilize STOPP and Beers Criteria to identify PIMs in geriatric patients at an inpatient psychiatric facility, with the goal of implementing a formal process for assessing medication regimens. This process would be expected to decrease adverse outcomes. Methods: Both criteria were used by the pharmacist to identify PIMs and recommendations were made to address the PIMs. A retrospective chart review evaluated whether utilization of the two criteria led to a significant change in number of PIMs and associated adverse outcomes. The primary outcome was the change in number of PIMs for the Beers Criteria versus the STOPP Criteria. Secondary outcomes included the change in number of PIMs, falls, required referrals/transfers, and medication-specific ADEs for each set of criteria assessed separately. Results: Twenty-nine patients met inclusion criteria, and 76 treatment recommendations were made. More PIMs per patient were identified at baseline utilizing STOPP (mean±SD,3.9±2.3) versus Beers Criteria (mean±SD, 2.2±1.3) (p<0.001). The number of PIMs decreased using STOPP (from 112 to 66; mean decrease per patient −1.6±1.5, p<0.0001) and Beers Criteria (from 63 to 23; mean decrease per patient −1.4±1.1, p<0.0001), although the change was not significant for STOPP vs. Beers (p=0.375). All secondary outcomes decreased using both criteria. Conclusions: Utilization of each set of criteria by the pharmacist led to a significant decrease in PIMs and adverse outcomes decreased at follow-up using both criteria. Implementation of a process for assessing medication regimens of geriatric patients utilizing the Beers and/or STOPP Criteria would likely be beneficial to this institution.

Aims: Elderly in Iraq kept suffering multiple burdens, as they are a truly fragile and vulnerable segment. A major public health issue among elderly is adverse drug reactions. This study is aimed at contributing in overcoming this treatment gap by determining the prevalence of inappropriate medications used by a group of Iraqi elderly outpatients. Methods: A cross-sectional, questionnaire-based study was conducted in a sample of 85 Iraqi elderly aged ≥65 years of either gender. Participants had face-to-face interviews to answer a comprehensive questionnaire. Each drug taken by the patient was evaluated according to Beers criteria. Results: Females constituted 45.9% of the total. The average age was 69.9 years (± 4.6). Nearly 30% of the patients had 3 different diseases, and 17.8% had ≥4 different ones, with cardiovascular diseases were the most prevalent. Polypharmacy was notably identified in 47.1% of the total studied population. Twenty-eight out of 85 patients did not know the actual reason of taking at least one of their medications, and 42% were not taking their drugs as directed. Remarkably, 43.5% of patients were recognized as taking at least one medication to be avoided in elderly people according to the Beers criteria. The most common inappropriate drugs were glyburide, and proton-pump inhibitors. Conclusion: There was an obvious absence of any role of pharmacists in the health care system for our studied population. Health care professionals are encouraged to review the medications prescribed for geriatric patients using updated safety guidelines to prevent the risks associated with potentially inappropriate medications.
