A Study of Polypharmacy and its Consequences in Geriatric Patients

The term polypharmacy is the concurrent use of five or more drug by a patient. In older persons, the cutoff threshold of five medicines is linked to the unfavourable outcomes such falls, disability, and mortality one of the crucial components. The main components of polypharmacy therapy in the clinical setting are reviewed in this study. Potential Drug-Drug Interactions (pDDIs) and Potentially Inappropriate Medications (PIMs) are threatening and contribute to increased rate of morbidity and mortality rate. The present study was performed on the prevalence of pDDIs and PIMs among the geriatric patients at a tertiary care hospital. Methodology: The study was Prospective, Cross-sectional study carried out for a period of six months in General Medical Ward at Akash hospital, Bangalore PIMs were analyzed using Beer’s criteria and pDDIs were analyzed using online data base system (Micromedex 2.2) Results: In this study, a total of 110 patients were enrolled, out of which 69 (62.72%) were males and 41 (37.28%) were females. Out of which 21 (19.10%) prescription showed PIMs and 66 (56%) prescription showed pDDIs. A total of 180 pDDIs were observed, 3 interactions (1.7%) come under the classification of contraindication, 87 (48.3%) fall under major severity, 85 (47.29%) were of moderate severity and 5 (2.8%) were of minor severity. Among 180 pDDIs, 13 (7.2%) were of rapid, 21 (11.6%) were delayed and 146 (81.6%) were not specified. 97 (57.30%) were of synergism, 49 (27.40%) were antagonism and 34 (18.80%) were unknown. 13 (7.2%) were of excellent, 29 (16.20%) were good and 138 (76.60%) were fair. Conclusion: This study concluded that awareness on the most prevalent pDDIs can help the practitioners to prescribe drugs with a low risk for pDDIs and prevent the concomitant use of various drug combinations.

Clinical impact of an individualised clinical pharmacy programme into the memory care pathway of older people: an observational study.

In older patients, medication exposure [i.e. polypharmacy, potentially inappropriate medications (PIMs), medications with anticholinergic and/or sedative properties] is a modifiable risk factor associated with cognitive iatrogenic risk and dementia. To assess the potential clinical impact of the implementation of an individualised clinical pharmacy programme at the initiation of the Memory care pathway in older patients with a cognitive complaint. This prospective observational study included older patients with high-risk of adverse drug event (HR) admitted in a French geriatric university hospital to explore the cognitive complaint or the cognitive disorder between January and November 2021. Drug-related problems (DRPs) were identified during a medication review performed in HR patients, and pharmaceutical interventions (PIs) notified in the patient's hospitalisation report were collected. The clinical impact of PIs was assessed by an expert panel (geriatricians and clinical pharmacists) using the Clinical, Economic, and Organisational (CLEO) tool. Overall, 326 patients were eligible and 207 (63.5%) were considered as HR patients. Among HR patients, 88.9% (n = 184) were treated using at least 5 medications (polypharmacy), and 36.7% (n = 76) received at least one PIM with cognitive iatrogenic risk. During the medication review, 490 PIs were provided and their clinical impact was rated as minor for 57.3% (n = 281), moderate for 26.7% (n = 131), and major for 2.5% (n = 12). The integration of clinical pharmacist secured the Memory care pathway of older patients with a cognitive complaint by identifying an important number of DRPs and PIMs with potential cognitive iatrogenic risk.

Development of a Predictive Model for Potentially Inappropriate Medications in Older Patients with Cardiovascular Disease.

Older patients with cardiovascular disease (CVD) are highly susceptible to adverse drug reactions due to age-related physiological changes and the presence of multiple comorbidities, polypharmacy, and potentially inappropriate medications (PIMs). This study aimed to develop a predictive model to identify the use of PIMs in older patients with CVD. Data from 2012 to 2021 from the Changhua Christian Hospital Clinical Research Database (CCHRD) and the Kaohsiung Medical University Hospital Research Database (KMUHRD) were analyzed. Participants over the age of 65 years with CVD diagnoses were included. The CCHRD data were randomly divided into a training set (80% of the database) and an internal validation set (20% of the database), while the KMUHRD data served as an external validation set. The training set was used to construct the prediction models, and both validation sets were used to validate the proposed models. A total of 48,569 patients were included. Comprehensive data analysis revealed significant associations between the use of PIMs and clinical factors such as total cholesterol, glycated hemoglobin (HbA1c), creatinine, and uric acid levels, as well as the presence of diabetes, hypertension, and cerebrovascular accidents. The predictive models demonstrated moderate power, indicating the importance of these factors in assessing the risk of PIMs. This study developed predictive models that improve understanding of the use of PIMs in older patients with CVD. These models may assist clinicians in making informed decisions regarding medication safety.

Early clinical and quality impacts of the Age-Friendly Health System in a Veterans Affairs skilled nursing facility.

Skilled nursing facilities (SNFs) are an ideal setting to implement the Age-Friendly Health System (AFHS) approach, an initiative by the Institute for Healthcare Improvement (IHI) centered on the 4Ms: what matters, mobility, mentation, and medication. AFHS implementation has not been well studied in SNFs. A 112-bed VA SNF implemented a facility-wide AFHS initiative including the following: (1) participating in a national IHI Age-Friendly Action Community; (2) establishing an AFHS workgroup centered on the 4Ms; (3) identifying meaningful clinical tools and frameworks for capturing each M; and (4) developing sustainment methods. Clinical (life-sustaining treatment, falls, disruptive behaviors, and medication deprescribing) and quality outcomes (rehospitalization, emergency department utilization, and discharge to the community) in addition to patient satisfaction were compared pre- and post-AFHS implementation (bed days of care [BDOC] 17413) to post-implementation (BDOC 20880). Clinical outcomes demonstrated improvements in the 4Ms, including: (1) what matters: 14% increase in life-sustaining treatment documentation (82%-96%; p < 0.01); (2) mobility: reduction in fall rate by 34% (8.15 falls/1000 BDOC to 5.41; p < 0.01); (3) mentation: decrease in disruptive behavior reporting system (DBRS) by 62% (5.11 DBRS/1000 BDOC to 1.96; p = 0.04); (4) medications: 53% increase in average potentially inappropriate medications (PIMs) deprescribing (0.38-0.80 interventions/patient; p < 0.01). Quality outcomes improved including rehospitalization (25.6%-17.9%) and emergency department utilization (5.3%-2.8%) within 30 days of admission. Patient satisfaction scores improved from a mean of 77.2 (n = 31, scale 1-100) to 81.3 (n = 42). Implementation of the AFHS initiative in a SNF was associated with improved clinical and quality outcomes and patient satisfaction. We describe here a sustainable, interprofessional approach to implementing the AFHS in a SNF.

Potentially Inappropriate Medication in Older Persons With Dementia: Does a Migration Background Matter?

ObjectivesPrevious research in the general population shows more potentially inappropriate medications (PIMs) among persons with a migration background compared with persons without a migration background. This study investigated the association between non-Western (nw) migration background (MB) and dementia-specific PIMs in older adults with dementia in the Netherlands. DesignCohort study using routinely recorded electronic health records and administrative data. Setting and ParticipantsElectronic health record data of general practitioners from the NIVEL-Primary Care Database, were linked to registries managed by Statistics Netherlands (2013-2014). A total of 9055 community-dwelling older adults with dementia were included, among whom 294 persons had an nw-MB from Africa, South America, or Asia, based on their country of birth. MethodsWe determined the presence of dementia-specific PIM prescriptions and compared this between persons with an nw-MB and without an MB, using logistic regression analysis adjusted for follow-up time, age, registered sex, and total number of prescriptions. Interaction effects of potentially relevant covariates were tested. The 3 largest nw-MB groups in the Netherlands were analyzed separately. ResultsDementia-specific PIMs were less frequently prescribed to persons with an nw-MB compared to persons without an MB with a dementia diagnosis [30.6% vs 34.4%, odds ratio (OR) 0.71, 95% CI 0.54-0.92], with especially less often a benzodiazepine prescription in the group with an nw-MB, compared to persons without an MB (15.0% vs 19.3%, OR 0.61, 95% CI 0.43-0.84). Dementia duration, living alone, household income, and degree of urbanization did not influence the associations. Conclusions and ImplicationsAmong older adults with dementia in the Netherlands, persons with an nw-MB had less often a dementia-specific PIM prescription compared to persons without an MB. Whether this difference is a reflection of better quality of care, higher professional uncertainty, or less recognition of (mental) health problems in persons with an nw-MB and dementia, needs further investigation.

Adopting STOPP/START Criteria Version 3 in Clinical Practice: A Q&A Guide for Healthcare Professionals.

The growing complexity of geriatric pharmacotherapy necessitates effective tools for mitigating the risks associated with polypharmacy. The Screening Tool of Older Persons' Potentially Inappropriate Prescriptions (STOPP)/Screening Tool to Alert doctors to Right Treatment (START) criteria have been instrumental in optimizing medication management among older adults. Despite their large adoption for improving the reduction of potentially inappropriate medications (PIM) and patient outcomes, the implementation of STOPP/START criteria faces notable challenges. The extensive number of criteria in the latest version and time constraints in primary care pose practical difficulties, particularly in settings with a high number of older patients. This paper critically evaluates the challenges and evolving implications of applying the third version of the STOPP/START criteria across various clinical settings, focusing on the European healthcare context. Utilizing a "Questions & Answers" format, it examines the criteria's implementation and discusses relevant suitability and potential adaptations to address the diverse needs of different clinical environments. By emphasizing these aspects, this paper aims to contribute to the ongoing discourse on enhancing medication safety and efficacy in the geriatric population, and to promote more person-centred care in an aging society.

A model for identifying potentially inappropriate medication used in older people with dementia: a machine learning study.

Older adults with dementia often face the risk of potentially inappropriate medication (PIM) use. The quality of PIM evaluation is hindered by researchers' unfamiliarity with evaluation criteria for inappropriate drug use. While traditional machine learning algorithms can enhance evaluation quality, they struggle with the multilabel nature of prescription data. This study aimed to combine six machine learning algorithms and three multilabel classification models to identify correlations in prescription information and develop an optimal model to identify PIMs in older adults with dementia. This study was conducted from January 1, 2020, to December 31, 2020. We used cluster sampling to obtain prescription data from patients 65 yearsand older with dementia. We assessed PIMs using the 2019 Beers criteria, the most authoritative and widely recognized standard for PIM detection. Our modeling process used three problem transformation methods (binary relevance, label powerset, and classifier chain) and six classification algorithms. We identified 18,338 older dementia patients and 36 PIMs types. The classifier chain + categorical boosting (CatBoost) model demonstrated superior performance, with the highest accuracy (97.93%), precision (95.39%), recall (94.07%), F1 score (95.69%), and subset accuracy values (97.41%), along with the lowest Hamming loss value (0.0011) and an acceptable duration of the operation (371s). This research introduces a pioneering CC + CatBoost warning model for PIMs in older dementia patients, utilizing machine-learning techniques. This model enables a quick and precise identification of PIMs, simplifying the manual evaluation process.

Prevalence of key potentially inappropriate drugs use in pediatrics: a cross-sectional study

BackgroundAppropriate drug prescribing in the pediatric population is challenging, given this age group’s unique pharmacokinetics. This has inevitably led to a high incidence of adverse drug reactions in this population. To address this issue, the Pediatric Pharmacy Association (PPA) compiled a list of 67 drugs that are inappropriately used in the pediatric population called the Key Potentially Inappropriate Drugs “KIDs list”.AimTo estimate the prevalence of potentially inappropriate medications (PIM) use in pediatric wards based on the KIDs list criteria.MethodsA retrospective observational study was conducted and included pediatric patients who were admitted to five pediatric wards during 3 years (2019–2021). The drugs in the KIDs list were matched to the hospital formulary and 11 matched drugs were included in the study. For each individual drug, the patient’s electronic file was reviewed to determine the prescription appropriateness according to the KIDs list criteria.ResultsAmong 3,166 pediatric patients admitted to pediatric wards, a total of 415 patients received a PIM listed in the KIDs list. The mean age was 8.6 (± 4.9) years old, and 60.0% (n = 251/415) were males. The overall prevalence of PIM use was 13.0% (n = 415/3166). Among the prescribed PIM, metoclopramide was the most commonly prescribed PIM 42.8% (n = 178/415), followed by tramadol 37.6% (n = 156/415).ConclusionGiven the high prevalence of inappropriate medication use in the pediatric wards, future research on strategies and interventions should be recommended to limit the use of PIMs and provide safer alternatives for the pediatric population.

Sex differences in patterns of potentially inappropriate prescribing and adverse drug reactions in hospitalized older people: Findings from the SENATOR trial.

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 older adults may be one reason for this ADR sex difference. In this secondary analysis, we examined whether incident ADR sex differences could be related to concurrent sex differences in potentially inappropriate prescribing. A retrospective secondary analysis of sex differences in the prevalence of potentially inappropriate medications (PIMs), potential prescribing omissions (PPOs), and ADRs among the 1537 participants (47.2% female, median [IQR] age 78 [72-84] years) was undertaken in the SENATOR clinical trial database, conducted in six large European medical centers. We looked specifically for male/female differences relating to PIMs and PPOs (defined by STOPP/START version 2 criteria) identified within 48 h of acute hospitalization. We also assessed sex differences for ADRs identified at 14 days from admission or discharge, whichever came first. ADRs were assessed by blinded endpoint adjudication panel consensus. During hospitalization, significantly more females experienced ≥1 ADR compared to males (28% and 21%, respectively; odds ratio 1.40, 95% CI 1.10-1.78, p < 0.005). Nine of the 11 STOPP-criteria PIMs showing a significant sex difference occurred more often in females. Of the four START-criteria PPOs showing a significant sex difference, all occurred more often in females. Some sex-associated PIMs reflect higher prevalence of related conditions in older women. We conclude that specific STOPP-criteria PIMs and START-criteria PPOs were identified more frequently in older women than older men during acute hospitalization, possibly contributing to higher ADR incidence in older women. Prescribers should appreciate sex differences in exposure to potentially inappropriate prescribing and ADR risk, given the preponderance of older women over older men in most clinical settings.

High rate of potentially inappropriate medication use in older people: a case–control study

Annually, 172 million fall events cause temporary or permanent impairment in older adults, and this number is increasing. Contributing factors that increase the risk for falls include age, polypharmacy, and malnutrition. This study evaluated medications mainly included in the EU(7)-PIM (potentially inappropriate medication) list. From March 21, 2022, to July 6, 2022, 945 patients who experienced a fall and visited the Department of Emergency Medicine at the Albert Szent-Györgyi Health Centre of the University of Szeged in Hungary. Data from 886 patients were collected (study group). The control group included 1364 patient data collected from three general practice in Hungary. The use of ≥ 2 EU(7)-PIM drugs was found to be associated with increased risk for falls (adjusted odds ratio [AOR], 1.38; 95% confidence interval [CI] 1.01–1.88). Piracetam (AOR, 1.81; 95% CI, 1.28–2.57) and trimetazidine (AOR, 1.62; 95% CI, 1.17–2.24) were associated with increased risk for falls. Doxazosin was associated with a low risk for falls (AOR, 0.59; 95% CI, 0.41–0.86). Tiapride (AOR, 3.54; 95% CI, 1.75–7.17), gliclazide (AOR, 1.57; 95% CI, 1.02–2.43), and vinpocetine (AOR, 1.95; 95% CI, 1.29–2.95) are not included in the EU(7)-PIM list; however, they are associated with increased risk for falls. Long-acting benzodiazepines (AOR, 1.79; 95% CI, 1.20–2.68), antidepressants (AOR, 1.89; 95% 95% CI, 1.37–2.61), serotonin–norepinephrine reuptake inhibitor (AOR, 2.82; 95% CI, 1.41–5.67; p < 0.01), and selective serotonin reuptake inhibitor (AOR, 1.88; 95% CI, 1.24–2.85) were also associated with increased risk for falls. However, Z-drugs were associated with a low risk for falls (AOR, 0.57; 95% CI, 0.36–0.92). With the help of this tool, trimetazidine and piracetam are filtered as EU(7)-PIM drugs associated with increased risk for falls.

Prescribing patterns and medications costs in patients on maintenance hemodialysis and peritoneal dialysis.

Polypharmacy is a significant clinical issue for patients on dialysis but has been incompletely studied. We investigated the prevalence and costs of polypharmacy in a population-based cohort of participants treated with hemodialysis (HD) or peritoneal dialysis (PD). We studied adults aged≥20 years in Alberta, Canada receiving maintenance HD or PD as of March 31, 2019. We characterized participants as users of 0-29 drug categories of interest and those aged≥65 as users/non-users of potentially inappropriate medications (PIM). We calculated the number of drug categories, daily pill burden, total annual cost, and annual cost per participant, and compared this to an age- and sex-matched cohort from the general Alberta population. Among 2248 participants (mean age 63 years; 39% female) on HD (n=1781) or PD (n=467), the median number of prescribed drug categories was 6 [interquartile range (IQR) 4, 8]; median daily pill burden was 8.0 (IQR 4.6, 12.6) pills/day, with 5% prescribed≥21.7 pills/day, and 16.5% prescribed≥15 pills/day. Twelve % were prescribed at least one drug that is contraindicated in kidney failure. The median annual per participant cost was ${\$}$3,831, totaling approximately ${\$}$11.6 million annually for all participants. When restricting to the 1063 participants aged≥65, the median number of PIM categories was 2 (IQR 1, 2), with a median PIM pill burden of 1.2 pills/day (IQR 0.5, 2.4). Compared to PD participants, HD participants had similar daily pill burden, higher use of PIM, and higher annual per participant cost. Pill burden and associated costs for participants on dialysis were more than 3-fold and 10-fold higher, respectively, compared to the matched participants from the general population. Participants on dialysis have markedly higher use of prescription medications and associated costs than the general population. Effective methods to de-prescribe in the dialysis population are needed.

Identification of seniors at risk (ISAR) score and potentially inappropriate prescribing: a retrospective cohort study.

Potentially inappropriate prescribing (PIP) is usually associated with a higher risk of adverse health outcomes. It is therefore important to identify PIP in older adults. However, there are no clear prioritisation strategies to select patients requiring prescription reviews. The aim of this study was to assess the association between the identification of seniors at risk (ISAR) score and the number of PIPs. A 12-month retrospective hospital-basedstudy was conducted. PIPs, including potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs), were detected using the STOPP/START tool. Multivariate linear regressions were conducted to identify factors associated with the number of PIPs. Sensitivity, specificity, Youden index, and ROC curve were calculated to determine the predictive power of ISAR score. This study included 266 records. The analysis led to the detection of 420 PIMs and 210 PPOs, with a prevalence of 80.1% and 54.9%, respectively. Multivariate linear regression revealed that the ISAR score (p = 0.041), and the number of medications (p < 0.001) were determinants of PIP. The number of medications remained the sole determinant of the number of PIMs (p < 0.001), while living in a nursing home was the only determinant of the number of PPOs (p = 0.036). The study showed that the ISAR score and the number of medications were independently associated with the number of PIPs. Considering the use of the ISAR score and the number of medications may be useful strategies to prioritise patients for whom prescribing appropriateness should be assessed using explicit criteria.

Potentially Inappropriate Use of Medication and Its Determinants Among Ambulatory Older Adults in Six Community Chain Pharmacies in Asmara, Eritrea: A Cross-Sectional Study Using the 2023 American Geriatric Society Beers Criteria®.

Potentially inappropriate medication (PIM) use is one of the main drug-related problems encountered in older adults. It is associated with adverse drug events, morbidity, mortality, increased economic costs, and negative effects on the quality of life that requires strict monitoring of prescriptions in older adults. Thus, the study aimed to assess potentially inappropriate medication use and its determinants among older adults. A cross-sectional study was conducted among all outpatient prescriptions dispensed to older adults (aged 65 years and above) in six community chain pharmacies in Asmara, Eritrea. Data were collected retrospectively, between June 16 and July 16, 2023. PIMs were detected using the 2023 American Geriatric Society (AGS) Beers Criteria®. Descriptive statistics and logistic regression analysis were performed using IBM SPSS® (Version-26.0). A total of 2680 outpatient prescriptions dispensed to older adults were included in this study. The prevalence of PIM among prescriptions was 18.1% (95% CI: 16.7, 19.6). Moreover, a total of 470 medications were found to be avoided in older adults. The most commonly prescribed PIMs were sulfonylureas (27.2%) and substituted alkylamines (16.2%). The prevalence of prescriptions containing medications to be used with caution in older adults was 13.2% (95% CI: 12.0, 14.5). Age (Adjusted Odds Ratio (AOR))=0.98, 95% CI: 0.97, 0.99), polypharmacy (AOR=2.77, 95% CI: 1.49, 5.15), and general practitioner prescriber (AOR=1.38, 95% CI: 1.11, 1.70) were significantly associated with PIMs. A considerable number of ambulatory older adults were exposed to PIMs which require a close attention by policymakers, program managers, and healthcare professionals.

Variability in the prevalence of inappropriate medication use among older adults: A review highlighting the importance of screening methods and database types.

The global older population is growing rapidly, and the rise in polypharmacy has increased potentially inappropriate medication (PIM) encounters. PIMs pose health risks, but detecting them automatically in large medical databases is complex. This review aimed to uncover PIM prevalence in individuals aged 65 years or older using health databases and emphasized the risk of underestimating PIM prevalence due to underutilization of detection tools. This study conducted a broad search on the Medline database to identify articles about the prevalence of PIMs in older adults using various databases. Articles published between January 2010 and June 2023 were included, and specific criteria were applied for study selection. Two literature reviews conducted before our study period were integrated to obtain a perspective from the 1990s to the present day. The selected papers were analysed for variables including database type, screening method, adaptations and PIM prevalence. The study categorized databases and original screening tools for clarity, examined adaptations and assessed concordance among different screening methods. This study encompassed 48 manuscripts, covering 58 sample evaluations. The mean prevalence of PIMs within the general population aged over 65 years was 27.8%. Relevant heterogeneity emerged in both the utilized databases and the detection methods. Adaptation of original screening tools was observed in 86.2% (50/58) of cases. Half of the original screening tools used for assessing PIMs belonged to the simple category. About a third of the studies employed less than half of the original criteria after adaptation. Only three studies used over 75% of the original criteria and more than 50 criteria. This extensive review highlights PIM prevalence among the older adults, emphasizing method intricacies and the potential for underestimation due to data limitations and algorithm adjustments. The findings call for enhanced methodologies, transparent algorithms and a deeper understanding of intricate rules' impact on public health implications.

Are primary care physicians familiar enough with potentially inappropriate medications in geriatric care? A cross-sectional study in the Eastern Province of Saudi Arabia.

Potentially inappropriate medications (PIMs) and polypharmacy constitute increasing healthcare costs and significant risk for adverse outcomes in older adults. The American Geriatrics Society Beers Criteria form a screening tool for the identification of PIMs and guidance for healthcare providers in prescribing appropriate medications. However, primary care physicians' knowledge of screening tools, of Beers Criteria, in particular, is not known. Therefore, this study was to investigate primary care physicians in the Eastern Province of Saudi Arabia and their awareness of Beers Criteria and knowledge of PIMs. This cross-sectional study was conducted among primary care physicians working in the Eastern Province of Saudi Arabia. Data were collected using an online self-administered questionnaire that consisted of sections on the general characteristics of respondents and their knowledge of Beers Criteria as a screening tool. Eight clinical-based vignettes concerning different therapeutic areas of medication use in the elderly were included, with a score of 1 and 0 for correct and wrong answers, respectively. Data presented as frequency and percentage. Chi-square test was used to determine the association between duration of practice and the level of awareness about Beers criteria. Of the 121 physicians who returned completed questionnaires, 41.3% of respondents knew about Beers Criteria. Most respondents (52.9%) were confident in prescribing appropriately for elderly patients. The association between the duration of practice and confidence level was statistically significant (P = 0.040). Respondents showed an above-average knowledge of the clinical vignettes with a correct answer rate >50% in all clinical scenarios. Online search (84.2%) and physician colleagues' knowledge and experiences (39.2%) were the primary source of information reported by the respondents. Awareness of Beers Criteria of primary care physicians in Saudi Arabia's Eastern Province is low. Therefore, our results will educate healthcare workers on the importance of Beers Criteria in Geriatric patients' prescriptions, in order to significantly improve the well-being of the elderly.

Pharmacist-Led Deprescribing Using STOPPFrail for Frail Older Adults in Nursing Homes

ObjectivesTo evaluate the impact of pharmacist-guided deprescribing using the STOPPFrail (Screening Tool of Older Persons' Prescriptions in Frail adults with a limited life expectancy) criteria in frail older nursing home residents. DesignProspective, unblinded, non-randomized, intervention study. Setting and ParticipantsAdults aged ≥65 years with advanced frailty resident in 6 independent nursing homes in Ireland. MethodsSTOPPFrail-based deprescribing recommendations were developed by a pharmacist and presented to residents’ general practitioners (GPs), who decided to implement or not. Measured outcomes included number of prescribed medications, medication costs, anticholinergic cognitive burden (ACB), drug burden index (DBI), modified medication appropriateness index (MMAI), quality of life (QoL), non-elective hospitalizations, emergency department visits, falls, and mortality were measured at baseline, post review, and at 6 months post review. ResultsNinety-nine residents were recruited. Most (94%) were prescribed ≥1 potentially inappropriate medication (PIM). The most frequent PIMs were medications without a clearly documented indication (29.6%) and vitamin D (16.9%). Of 348 recommendations provided to GPs, 203 (58%) were accepted and 193 (55%) were implemented. Relating to baseline, post review, and at 6 months: the mean ± standard deviation (SD) number of medications was 16.0 ± 6.1, 14.6 ± 5.7 (P < .001), and 15.4 ± 5.5 (P < .001). The monthly mean ± SD medication cost per patient was €186.8 ± 123.7, €172.7 ± 119.0 (P < .001), and €186.4 ± 121.2 (P = .95). There were significant post-review decreases in the mean DBI, ACB, and MMAI of 9.7%, 9.6%, and 3.7%, respectively (P < .001), which remained significant at 6 months (P < .001). There were no significant differences in falls, emergency department visits, non-elective hospitalizations, or QoL. Conclusions and ImplicationsSTOPPFrail-guided deprescribing led by a pharmacist in nursing homes appeared to significantly reduce PIMs, medication costs (initially), and anticholinergic and sedative burdens, without adversely affecting other patient outcomes. Greater consideration should therefore be given to the wider integration of pharmacists into nursing homes to optimize the medications and health outcomes of frail older adults.

A Systematic Review of Healthcare Providers Awareness of Medication Switching for Polypharmacy Patients in Saudi Arabia

Background: Polypharmacy, the concurrent use of multiple medications by an individual, presents challenges in medication management, patient safety, and healthcare outcomes, particularly among older adults. In Saudi Arabia, the prevalence of polypharmacy is increasing due to the aging population and the burden of chronic diseases. Understanding healthcare providers' awareness and practices regarding medication switching is crucial for optimizing medication use and improving patient outcomes. Study Aim: This systematic review aims to synthesize and analyze existing literature on healthcare providers' awareness of medication switching for polypharmacy patients in Saudi Arabia. The study focuses on pharmacists and physicians, exploring their knowledge, attitudes, and practices related to medication management, deprescribing, pharmacovigilance, and Medication Therapy Management (MTM) services. Methodology: A systematic search was conducted across major databases, including PubMed, Scopus, and Google Scholar, using predefined search terms related to polypharmacy, medication switching, healthcare providers' awareness, and Saudi Arabia. Eligible studies were selected based on inclusion criteria, including study design, setting, participants, and relevance to the study aim. Data extraction and synthesis were performed to analyze key findings and themes related to healthcare providers' awareness of medication switching. Results: Six eligible studies were included in the systematic review, encompassing survey-based investigations, cross-sectional studies, and qualitative studies conducted in various healthcare settings across Saudi Arabia. The findings revealed gaps in pharmacists' and physicians' knowledge regarding Potentially Inappropriate Medications (PIMs), Drug-Drug Interactions (DDIs), pharmacovigilance practices, and deprescribing strategies. Recommendations for improving pharmacists' education, enhancing pharmacovigilance practices, and promoting collaborative care models were highlighted. Conclusion: Healthcare providers in Saudi Arabia demonstrate varying levels of awareness and practices regarding medication switching for polypharmacy patients. There is a need for targeted educational interventions, standardized pharmacovigilance practices, and collaborative efforts among healthcare providers to optimize medication use, reduce polypharmacy-related risks, and improve patient outcomes.

Potentially Inappropriate Medication: A Pilot Study in Institutionalized Older Adults.

Institutionalized older adults often face complex medication regimens, increasing their risk of adverse drug events due to polypharmacy, overprescribing, medication interactions, or the use of Potentially Inappropriate Medications (PIM). However, data on medication use and associated risks in this population remain scarce. This pilot study aimed to characterize the sociodemographic, clinical and pharmacotherapeutic profiles, and the use of PIM among institutionalized elders residing in Residential Structures for Elderly People (ERPI) in the Faro municipality, located in the Portuguese region of the Algarve. We conducted a cross-sectional study in a non-randomized sample of 96 participants (mean age: 86.6 ± 7.86 years) where trained researchers reviewed medication profiles and identified potentially inappropriate medications using the EU(7)-PIM list. Over 90% of participants exhibited polypharmacy (≥5 medications), with an average of 9.1 ± 4.15 medications per person. About 92% had potential drug interactions, including major and moderate interactions. More than 86% used at least one potentially inappropriate medication, most commonly central nervous system drugs. This pilot study demonstrates that institutionalized older adults may be at high risk of potential medication-related problems. Implementing comprehensive medication review programs and promoting adapted prescribing practices are crucial to optimize medication use and improve the well-being of this vulnerable population.

Association of potentially inappropriate medications with prognosis among older patients with non-small cell lung cancer

BackgroundPotentially inappropriate medications (PIMs) are common among older adults with cancer, but their association with overall survival (OS) among non-small cell lung cancer (NSCLC) patients remains unclear. This study aimed to investigate the association between the use of PIMs and OS in patients with NSCLC.MethodsIn this cohort study, we included patients ≥ 65 years with newly diagnosed NSCLC from January 2014 to December 2020. Potentially inappropriate medication (PIM) is defined by the Beers criteria of 2019 at baseline and within six months following the initiation of systemic therapy. Multivariable Cox regression model was built to assess the association between PIMs and overall survival (OS).ResultsWe finally included 338 patients with a median follow-up for OS of 1777 days. The prevalence of patients receiving at least one PIM was 39.9% (135/338) and 61.2% (71/116) at baseline and after systemic therapy, respectively. The most important factor associated with PIM use was the number of prescribed medications (P < 0.001). Baseline PIM use and PIM after systemic therapy were significantly associated with inferior OS (476 days vs. 844 days, P = 0.044; and 633 days vs. 1600 days, P = 0.007; respectively). In multivariable analysis, both baseline PIM use and PIM after systemic therapy were independent predictors of poor prognosis (adjusted HR, 1.33; 95% CI, 1.01–1.75; P = 0.041; and adjusted HR, 1.86; 95% CI, 1.11–3.14; P = 0.020; respectively).ConclusionsPIMs are prevalent among older patients with NSCLC and are independent predictors of NSCLC prognosis. There is an urgent need for clinicians to conduct medication reconciliation and appropriate deprescribing for this population, especially for patients with multiple PIMs.
