Abstract
The relatively new discipline of pharmacovigilance (PV) aims to monitor the safety of drugs throughout their evolution and is essential to discovering new drug risks. Due to their specific and complex physiology, children, pregnant women, and elderly adults are more prone to adverse drug reactions (ADRs). Additionally, the lack of clinical trial data exacerbates the challenges faced with pharmacotherapy in these populations. Elderly patients tend to have multiple comorbidities often requiring more extensive medication, which adds additional challenges for healthcare professionals (HCPs) in delivering safe and effective pharmacotherapy. Clinical trials often have inherent limitations, including insufficient sample size and limited duration of research; as some ADRs are attributed to long-term use of a drug, these may go undetected during the course of the trial. Therefore, the implementation of PV is key to insuring the safe and effective use of drugs in special populations. We conducted a thorough review of the scientific literature on PV systems across the European Union, the United States, and China. Our review focused on basic physiological characteristics, drug use, and PV for specific populations (children, pregnant women, and the elderly). This article aims to provide a reference for the development of follow-up policies and improvement of existing policies as well as provide insight into drug safety with respect to patients of special populations.

Abstract
Background Multimorbidity and polypharmacy are common problems among the older population globally. They not only reduce the quality of life of older adults but also increase the prevalence of potentially inappropriate medication (PIM) use. This study aimed to examine the prevalence and the predictors of PIMs in hospitalized geriatric patients with multimorbidity and polypharmacy in Chengdu based on the 2015 American Geriatric Society Beers Criteria (2015 AGS Beers Criteria) and 2019 American Geriatric Society Beers Criteria (2019 AGS Beers Criteria). Methods From 2016 to 2018, a cross-sectional study was conducted using electronic medical data from nine tertiary hospitals in Chengdu. The 2019 and 2015 AGS Beers Criteria were used to evaluate the PIM status of older inpatients (age ≥65 years), and logistic regression was used to identify the risk factors for PIM use. Results A total of 17,352 inpatients were included in the study between 2016 and 2018. The prevalence of PIM use based on the 2019 AGS Beers Criteria (72.54%) was slightly higher than that based on the 2015 AGS Beers Criteria (70.10%). Further, the prevalence of PIM use based on the 2019 AGS Beers Criteria showed an increasing trend, from 71.17% in 2016 to 73.39% in 2018. Logistic regression demonstrated that female, advanced age, and polypharmacy were positively associated with PIM use in older adults. The most frequently used PIMs in the inpatients were diuretics, benzodiazepines, non-steroidal anti-inflammatory drugs, antipsychotics, and selective serotonin reuptake inhibitors. Conclusions There is a high prevalence of PIM use in older inpatients with multimorbidity and polypharmacy in Chengdu. The 2019 AGS Beers Criteria is more sensitive for evaluating older adults in Chengdu than the 2015 AGS Beers Criteria. Further, based on the 2019 AGS Beers Criteria, the prevalence of PIM use is increasing year by year. Research on interventions rationing PIM use in the geriatric population in Chengdu are necessary in the future.

Abstract
BACKGROUND AND AIMS Inappropriate medication prescription is highly prevalent in older adults and is associated with adverse health outcomes. The aim of this study was to examine the associations between potentially inappropriate medications (PIMS) and potential prescribing omissions with physical function in older adults situated in diverse environments. METHODS A systematic search was completed using the following databases: MEDLINE, CINAHL, PsycINFO, EMBASE and COCHRANE. Results were extracted from the included studies. RESULTS In total, 55 studies reported on 2,767,594 participants with a mean age of 77.1 years (63.5% women). Study designs comprised 26 retrospective cohort studies, 21 prospective cohort studies and 8 cross-sectional studies. Inappropriate medications in community and hospital settings were significantly associated with higher risk of falls (21 out of 30 studies), higher risk of fractures (7 out of 9 studies), impaired activities of daily living (ADL; 8 out of 10 studies) and impaired instrumental ADL (IADL) score (4 out of 6 studies). Five out of seven studies also showed that PIMs were associated with poorer physical performance comprising the Timed Up and Go test, walking speed, grip strength, time to functional recovery, functional independence and scale of functioning. Many medication classes were implicated as PIMs in falls, fractures and impairment in physical performance including antipsychotic, sedative, anti-anxiety, anticholinergic, antidiabetic, opioid and antihypertensive medications. For patients not receiving musculoskeletal medications, such as calcium, vitamin D and bisphosphonates, older adults were found to be at risk of a hospital admission for a fall or fracture. CONCLUSION Inappropriate medication prescriptions are associated with impaired physical function across longitudinal and cross-sectional studies in older adults situated in diverse settings. It is important to support older people to reduce their use of inappropriate medications and prevent prescribing omissions. PLAIN LANGUAGE SUMMARY Inappropriate medications and physical function Background and aims: The use of inappropriate medications is very common in older adults and is associated with harmful health problems. The aim was to examine associations between potentially inappropriate medications and potential prescribing omissions with physical function in older adults situated in diverse environments. Methods: Library databases were examined for possible studies to include and a systematic search was completed. Relevant information was obtained from the included studies. Results: In total, 55 studies reported on 2,767,594 participants who were an average age of 77.1 years and about 6 out of 10 were women. A variety of different study designs were used. Inappropriate medication prescriptions in community and hospital settings were significantly associated with higher risk of falls (21 out of 30 studies), higher risk of fractures (7 out of 9 studies), problems with activities of daily living (ADL), such as eating, bathing, dressing, grooming, walking and toileting (8 out of 10 studies) and problems with instrumental ADL such as managing medications, house cleaning and shopping (4 out of 6 studies). Five out of seven studies also showed that inappropriate medications were associated with poorer physical performance involving the Timed Up and Go test, walking speed, grip strength, time to functional recovery, functional independence and scale of functioning. Many types of medication classes were shown to be associated with a risk of falls, fractures and problems with physical performance. Omitted medications were also associated with falls and fractures. Conclusion: Inappropriate medication prescriptions are associated with problems relating to physical function. It is important to support older people to reduce their use of inappropriate medications and prevent prescribing omissions.

Abstract
WHAT IS KNOWN AND OBJECTIVE The Beers, European Union (EU) and Screening Tool of Older Persons' potentially inappropriate Prescription (STOPP) criteria were developed to improve the safe use of medicines in the elderly. However, the predictive validity of existing criteria to detect adverse drug reactions (ADRs) remains unexplored. The objective of the current study was to determine whether the 2019 Beers, 2015 STOPP or 2015 EU potentially inappropriate medicine (PIM) criteria were associated with ADRs. METHODS A retrospective, cross-sectional investigation was conducted among older persons (≥60 years of age) admitted to a tertiary hospital in China between April 2019 and December 2019. PIMs were identified as per the Beers, EU and STOPP criteria definitions. ADRs were retrospectively evaluated by two clinical pharmacists using the Naranjo algorithm. Multivariate logistic regression was used to evaluate the factors associated with ADRs in the hospitalized patients. RESULTS AND DISCUSSION The study participants included 560 hospitalized patients (mean age 72.05 ± 8.15). The prevalence of patients receiving at least one PIM was 52.1%, 37.0% and 42.9% according to the Beers, EU and STOPP criteria, respectively. Univariate analysis showed that ADRs were associated with PIMs listed in the Beers criteria (OR: 2.093, 95% CI: 1.028-4.263, 0.042), but not with the STOPP-listed (OR: 0.536, 95% CI: 0.255-1.123, 0.098) and EU-listed PIMs (OR: 0.258, 95% CI: 0.118-0.563, 0.001). WHAT IS NEW AND CONCLUSION In contrast to the STOPP and EU criteria on PIMs, the Beers criteria were significantly associated with avoidable ADRs in hospitalized older persons.

Abstract
Background: The use of drugs with anticholinergic effects among elderly patients is associated with adverse clinical outcomes. There is paucity of information about anticholinergic drug burden among Nigerian elderly population. Objectives: To determine the anticholinergic drug burden among elderly Nigerian patients. Methods: This was a retrospective cross-sectional study conducted among elderly patients (aged 65 and above) who visited the Family Medicine outpatients' clinics of the Ekiti State University Teaching Hospital, Ado-Ekiti, Nigeria between July 1 and October 31, 2018. Information extracted from the case files included patient's age, sex, diagnoses, and list of prescribed medications. Medicines with anticholinergic effects were identified and scored using the anticholinergic drug burden calculator (http://www.acbcalc.com). Results: The medical records of 400 patients were analyzed with females accounting for 60.5% of the study population. The mean age of participants was 73 ± 7.4 years with only 28 (7%) of patients having more than two co-morbid conditions. Polypharmacy was identified in 152 (38%) of the patients while 147 (36.7%) had drugs with anticholinergic effects prescribed. The anticholinergic burden was high in 60 (15%) patients. Polypharmacy was significantly associated with having more than two diagnosed conditions and high anticholinergic burden (p value of < 0 .001 and 0.013 respectively). There was significant correlation between total number of prescribed drugs and count of diagnoses (r = 0.598; p < 0 .000) and between total number of prescribed drugs and number of drugs with anticholinergic effects (r = 0 .196; p < 0 .000). Conclusion: The anticholinergic burden in this group of elderly Nigerian patients was low; majority (67%) had no exposure to drugs with anticholinergic effects with only 15% having high anticholinergic burden. Polypharmacy and multiple diagnosed conditions were positively associated with high anticholinergic burden. Based on the positive and significant correlations found in this study, a reduction in the number of prescribed medicines especially those with significant anticholinergic effects used for secondary indications may lessen the anticholinergic burden among the elderly.

Abstract
Background: The aging process makes geriatric populations more prone to various chronic diseases. Such diseases require older patients to be on more medications than any other age group and make them more susceptible to adverse drug events related to potentially inappropriate medications (PIMs). Aim: To identify the prevalence of potentially inappropriate medications among older people and explore the most commonly prescribed PIMs in hospitalized patients. Design and Setting: A retrospective study conducted in a large tertiary hospital among patients hospitalized in a 4 year period from January 2015 to December 2018. Methods: The 2019 Beers Criteria were used to assess PIMs in all inpatient prescribed medications focusing on the first class (i.e., drug/drug class to be avoided in older adults). Results: The mean age was 75.17 ± 7.66 years. A total of 684 (80.6%) patients were prescribed at least one medication listed in the first-class category of the 2019 Beers Criteria. Top five drugs were proton pump inhibitors (40.3%), nonsteroidal anti-inflammatory drugs (10.2%), metoclopramide (9.3%), benzodiazepines (8.4%), and insulin (5.4%). Conclusions: The prevalence of PIMs is high among older patients admitted to the hospital. More efforts are needed to investigate the potential reasons and develop action plans to improve concordance to Beers Criteria among healthcare providers.

Abstract
RATIONALE, AIMS AND OBJECTIVES There are currently no criteria to guide appropriate prescribing to older persons in Africa. Although the American Geriatrics Society-Beers (AGS-Beers) Criteria appear to be favoured by African researchers, there is a need to adapt its recommendations to the continent's health care systems. This study aimed to adapt the AGS-Beers recommendations to Nigerian and South African health care contexts. METHODS A modified Delphi technique was used to explore Nigerian and South African experts' consensus on the applicability of the 2015 AGS-Beers Criteria recommendations to older persons in Africa. Thirty-two recommendations, 21 from the parent Criteria and 11 modified, were explored among 10 purposively selected medical and pharmacy experts in a predetermined two-round survey that utilized a 5-point Likert scale. Consensus was defined as a lower-limit 95% CI mean ratings of ≥3.0. RESULTS Overall, the experts reached consensus on 62.5% (20/32) of the recommendations and 76.2% (16/21) of the parent AGS-Beers' recommendations specifically. While the experts consensually agreed that medications with strong anticholinergic effects should be generally avoided in older persons, mean = 4.11 (SD = ±1.27, 95% CI, 3.14-5.09), they could not reach a consensus on the context-specific recommendation to avoid amitriptyline in neuropathic pain mean = 3.11 (SD = ±1.05, 95% CI, 2.30-3.92). CONCLUSIONS The 2015 AGS-Beers Criteria were adapted to the Nigerian and South African health care contexts. The adapted and the parent recommendations differed in their context specificity. The recommendations may serve as a guide to clinicians when prescribing medications to older persons in Nigeria and South Africa.

Abstract
RATIONALE, AIMS, AND OBJECTIVES Inappropriate prescribing is associated with preventable morbidity and mortality in the elderly. The American Geriatrics-Beers (AGS-Beers) Criteria was developed to guide healthcare professionals (HCPs) to prescribe medications appropriately in the elderly. However, there is a dearth of information about the knowledge and awareness of HCPs of these criteria, and their perceptions of appropriate prescribing in the elderly. This study aimed to evaluate the knowledge and perceptions of Nigerian and South African HCPs about appropriate prescribing in the elderly. METHOD A 32-item questionnaire was self-administered among consecutively selected HCPs (physicians, nurses, and pharmacists) in one teaching hospital each in Nigeria and South Africa. Seven questions including six clinical vignettes from the 2015 AGS-Beers Criteria were used to assess the participants' knowledge.The participants' knowledge was classified based on the total score as poor (0-3), fair (4, 5), and good (6, 7). The HCPs' perceptions of appropriate prescribing in the elderly were evaluated using a 5-point Likert scale. Mann-Whitney U test was used to evaluate ranked variables at P < .05. RESULTS A total of 369 participants, 62.9% (232/369) mean age 42.75(9.35) years in Nigeria and 37.1% (137/369), mean age 38.66 (7.76) years, (CI = 2.32-5.87, P < .001) in South Africa were evaluated. Many participants in Nigeria (52.6%) and 48.2% in South Africa had scores (4, 5).The majority of the participants (57.3%) in Nigeria and 67.2% in South Africa were not aware of any explicit criteria for prescribing to the elderly while 45.8% of the total participants with no significant difference between the groups (P = .332) "strongly agreed" or "agreed" that the basic professional training is adequate for prescribing medicines to the elderly. CONCLUSIONS Many HCPs in Nigeria and South Africa had a fair knowledge of appropriate prescribing to the elderly and considered basic professional training as adequate for appropriate prescribing to the elderly.

Potentially inappropriate medications in Chinese older adults: a comparison of two updated Beers criteria. Int J Clin Pharm 2020; 43:229-235. [PMID: 32920684 DOI: 10.1007/s11096-020-01139-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Revised: 08/22/2020] [Accepted: 08/25/2020] [Indexed: 10/23/2022]
Abstract
Background Beers criteria have been into the mainstay to characterize the potentially inappropriate medication since its first publication, but the recent version, Beers 2019, is yet to be validated by clinical studies nationally. Objective To identify the prevalence and the predictors of potentially inappropriate medications in hospitalized geriatric patients based on the Beers 2019 and 2015 criteria. Setting Nanjing Drum Tower Hospital, a 3000-bed tertiary care teaching hospital in China. Method We conducted a cross-sectional study from July 1, 2018 to December 31, 2018. Data from all hospitalized patients aged ≥ 65 years were collected from the hospital database. Inappropriate prescriptions were identified using the Beers 2019 criteria and the Beers 2015 criteria. Main outcome measure Prevalence Ratio (PR) and predictors of potentially inappropriate medications. Results The prevalence of inappropriate prescriptions based on the Beers 2019 criteria was 64.80%. This result was slightly higher than that of the Beers 2015 criteria (64.31%). The most commonly encountered inappropriate prescriptions identified using the two criteria were proton-pump inhibitors. The kappa coefficient was 0.826 (p < 0.001) indicating a strong coherence between the two criteria. The most important factor associated with inappropriate medications use was the number of prescribed drugs (PR 5.17, 95% CI 2.89-8.43; PR 4.58, 95% CI 1.93-7.25). Conclusion This study showed a high prevalence of potentially inappropriate medication in the Chinese geriatric population, which was associated with the number of prescribed drugs. The predictors identified in this research might help pharmacists to detect high-risk drugs and intervene in time.

Abstract
OBJECTIVES Polypharmacy is common in older adults and associated with adverse drug events (ADEs). Several methods have been described in studies to help correlate ADE causation. We performed a narrative review to identify methods for ADE adjudication. We compared their strengths and limitations to assess their applicability to deprescribing studies (of which clinical trials are a subset) and to encourage the use of a standardized method in future studies. DESIGN We performed a review of original articles (1946-2019) using the Medline (Ovid) and Cochrane databases. We also conducted a manual reference search of review articles. Abstracts were screened for relevance. MEASUREMENTS Adjudication methods were compared for advantages and limitations including validity, ease of use, and applicability to clinical trials with deprescribing as the primary intervention. RESULTS The search yielded 1881 articles of which 175 articles were included for full-text review. Following in-depth review, 135 were excluded: 79 had no ADE outcome data, 35 were not specific to older adults, 9 were not relevant, 6 were review articles, 5 contained duplicate data, and 1 was not written in French or English. Forty articles remained for analysis, from which we identified 10 unique ADE adjudication methods. No method was developed originally for use in a deprescribing setting. CONCLUSION A standard method to identify ADEs is important to capture the outcome reliably in deprescribing studies. All methods we identified had limitations in terms of capturing adverse events from the withdrawal of medications. Future work should focus on refining adjudication methods for capturing ADEs related not only to medication continuation and new drug starts but also to deprescribing and drug discontinuation.

Front Pharmacol 2019; 10:592. [PMID: 31214031 PMCID: PMC6554676 DOI: 10.3389/fphar.2019.00592] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 05/08/2019] [Indexed: 02/02/2023] Open
Abstract
Background: Prescription and use of inappropriate medications have been identified as a major cause of morbidity among the elderly. Several screening tools have been developed to identify inappropriate medications prescribed for elderly patients. There is dearth of information about the knowledge of Nigerian physicians regarding these screening tools and appropriate prescribing for the elderly in general. The primary objective of this study was to assess the knowledge of Nigerian physicians about these screening tools and appropriate prescribing of medications for the elderly. Methods: The study was a cross-sectional questionnaire-based study conducted among physicians working in Family Medicine and Internal Medicine departments of four tertiary health care facilities in Nigeria. The questionnaire consisted of sections on general characteristics of respondents and their knowledge of four selected screening tools for inappropriate medications in the elderly. Ten clinical vignettes representing different therapeutic areas (using the best option type questions) about medicine use in the elderly were included with a score of 1 and 0 for correct and wrong answers, respectively. The knowledge of respondents was classified as (total score, over 10): poor (score, < 5), average (score, 5-6), and good (score, 7-10). Results: One hundred and five physicians returned completed questionnaires. Twenty percent of respondents knew about Beers criteria, whereas 15.6% were familiar with the STOPP criteria. Majority (83; 84.7%) of the respondents were confident of their ability to prescribeappropriately for elderly patients. The mean knowledge score was 5.3 ± 2.0 with 32 (30.5%), 41 (39%), and 32 (30.5%) having low, average, and good scores, respectively. The association between the knowledge score, duration of practice, and seniority was statistically significant (OR, 3.6, p = .004 and OR, 3; p = .012), respectively. Conclusion: There are significant gaps in the knowledge of Nigerian physicians about screening tools for inappropriate medications. There is a need for stakeholders involved in the care of elderly Nigerian patients to develop new strategies to improve services being offered. These may include introduction of modules on appropriate prescribing in the curriculum of undergraduate and postgraduate medical education and the routine use of some screening tools for inappropriate medications in daily clinical practice.
