Reviewing Potentially Inappropriate Medication in Hospitalized Patients Over 65 Using Explicit Criteria: A Systematic Literature Review

Acute Pain Management for the Older Adult

Treating older adults with acute pain in the emergency department is complicated. Undertreated pain can lead to delirium and functional decline. Conversely, common analgesics pose risks of serious drug-drug interactions and adverse drug events. In this review, we discuss issues essential to pain management in older adults including (1) assessing pain in the cognitively impaired, (2) review of analgesic medication classes, (3) principles of geriatric pharmacology, and (4) selecting an analgesic for an older adult with acute pain.

International Deprescribing Guidelines Did Not Impact Actual Practice in Deprescribing of Potentially Inappropriate Medications for Nursing Home Residents: An Interrupted Time Series Analysis

BACKGROUND

Deprescribing guidelines reduce the use of potentially inappropriate medications (PIMs) in trial settings; however, their real-world impact remains unclear. Therefore, this study assesses deprescribing trends and the impact of guideline publications (STOPPFrail, proton pump inhibitors [PPIs], and antipsychotics) on these trends among nursing home residents with limited life expectancy in Belgium.

METHODS

Deprescribing was assessed using linked healthcare reimbursement data for all residents aged 65 years and older who died between 2014 and 2019. In total, 15 PIMs from STOPPFrail version 1 were selected. Deprescribing was operationalized as discontinuing at least one PIM in the last 4 months of life among those who had been prescribed these medications chronically between 6-12 months prior to death. To identify changes in the trend of deprescribing, we employed a joinpoint linear regression model. We calculated the average quarterly percent change (AQPC) and 95% confidence intervals (CIs). In addition, we used autoregressive integrated moving average (ARIMA) modeling to explore the impact of publication of these guidelines on four commonly used PIMs: PPIs, antipsychotics, lipid modifying agents, and calcium.

RESULTS

Among 244,865 residents, 169,782 (69.3%) were chronically prescribed at least one PIM and 50,487 (29.7%) had at least one discontinued. The prevalence of deprescribing declined from 31.7 to 27.66% between the first quarter of 2014 and the fourth quarter of 2019, with an average quarterly percent change decline of - 0.47% (95% CI - 0.85, - 0.10). No joinpoints were identified, indicating a consistent linear trend with no interruptions or statistically significant shifts in the rate of change in deprescribing prevalence. ARIMA modeling found that the publication of deprescribing guidelines had no impact on deprescribing trends.

CONCLUSIONS

Despite the high use of PIMs, and the publication of the STOPPFrail, PPI, and antipsychotic deprescribing guidelines, deprescribing rates remained low and even decreased. These findings emphasize the importance of implementation efforts that go well beyond guideline publications to effectively change deprescribing practices.

Identification of the Potential Pharmacotherapeutic Risk in Hospitalized Geriatric Patients

INTRODUCTION

Geriatric patients need carefully tailored pharmacotherapeutic approaches to minimize the risks of inappropriate treatment and hospitalizations. In Slovakia, there is a lack of studies documenting the medication use patterns in hospitalized geriatric patients. The primary outcome of our study was to identify potential pharmacotherapeutic risks in hospitalized geriatric patients.

METHODS

We performed a retrospective analysis of the medical records from 122 patients (65 years and older) hospitalized in the geriatric department. Potential pharmacotherapeutic risk was assessed by identifying potential drug-drug interactions (PDIs) and potentially inappropriate medications (PIMs). PDIs were identified using the Lexicomp® database, and PIMs were evaluated using the EU(7)-PIM list. PDIs were classified into five severity categories: A (unknown), B (minor), C (moderate), D (major), and X (contraindicated). Patients' medication was labeled as "PDIs in the therapy" or "PIMs in the therapy" based on the presence of PDIs or PIMs. If PDIs were identified, the patient was labeled "PDI in therapy"; if PIMs were found, the label "PIMs in the therapy" was applied.

RESULTS

Polypharmacy (61.5%, 75 patients) and hyperpolypharmacy (16.4%, 20 patients) were highly prevalent. PDIs were identified in 80.3% of patients (98 patients). Out of the total 417 PDIs, eight were contraindicated (type X) and 47 were classified as major (type D) interactions. PIMs were used by 73.8% of patients (90 patients), with the most common being pantoprazole (37.7%, 46 patients), alprazolam (27.8%, 34 patients), and digoxin (15.6%, 19 patients). We found a moderate relationship between the number of used drugs and the number of PIMs (ρ = 0.574, R2 = 0.8697, p < 0.001). The mean number of hospitalizations was higher in patients with PDI in therapy (p < 0.001), had a weak relationship with the number of PDIs (p < 0.05), and did not correlate with the number of used drugs or PIMs. Only 6.6% of patients (eight patients) had no potential pharmacotherapeutic risk, while 32% (39 patients) had mild risk (PDIs or PIMs), and 61.5% (75 patients) had high risk (both PDIs and PIMs in the therapy).

CONCLUSION

Our results underscore the urgent need for medication reviews by hospital pharmacists and the active promotion of drug deprescription among clinicians.

The prevalence and factors associated with potentially inappropriate medications in Chinese older outpatients with heart failure

BACKGROUND

Potentially inappropriate medications (PIMs) can lead to adverse outcomes. This study aimed to investigate the prevalence of PIMs in older Chinese outpatients with heart failure according to the 2019 Beers criteria and the factors associated with PIMs.

METHODS

A cross-sectional retrospective study was conducted using electronic medical data during January 1, 2020 to December 31, 2020 from 9 tertiary medical institutions in Chengdu, China. Outpatients aged 65 and above who were diagnosed with heart failure were included. The 2019 Beers criteria were used to evaluate the PIM status of older outpatients, and binary logistic regression was used to identify potential risk factors for PIMs.

RESULTS

There were 3626 prescriptions. The prevalence of PIMs among older outpatients with heart failure was 67.98% according to the 2019 Beers criteria. Diuretics, non-steroidal anti-inflammatory drugs (NSAIDs), benzodiazepine receptor agonist hypnotics, rivaroxaban, and dabigatran were the top five PIMs. The risks of PIMs were associated with the number of drugs prescribed and comorbidities. PIMs were shown to be more common in patients with polypharmacy (5-9 medications, OR: 10.403, 95% CI: 8.258-13.104, p < 0.001; ≥10 medications, OR: 35.018, 95% CI: 10.545-116.293, p < 0.001), valvular heart disease (OR: 1.537, 95% CI: 1.109-2.131, p = 0.010), and insomnia (OR: 2.655, 95% CI: 1.809-3.898, p < 0.001). While, medicare reimbursement (OR: 0.678, 95% CI: 0.570-0.808, p < 0.001) and visits to the geriatric departments (department of cardiology, OR: 1.687, 95% CI: 1.214-2.344, p = 0.002) were protective factors.

CONCLUSIONS

The prevalence of PIMs use was high among older Chinese outpatients with heart failure, according to this study. Multidisciplinary teams should cooperate to reduce PIMs in older adults.

Study protocol: The effect of a Medication Coordinator on the quality of patients' medication treatment (MEDCOOR)-Randomized controlled trial

Patients' safety can be compromised in the transition of care between healthcare sectors. Optimal information flow across healthcare sectors and individualized medication treatment tailored to each patient is vital to prevent adverse events like drug-related problems. When medication changes are made during hospitalization, it is essential to ensure that the relevant general practitioner (GP) is included in the communication chain. This randomized controlled trial examines the effect of a Medication Coordinator who facilitates medication reviews in close collaboration with patients using My Medication Plan. Patients in the intervention group receive the medication review in combination with including suggested medication amendments documented in their electronic discharge letter send, which is sent to their GP. The patients randomized to the control group receive standard care by the ward staff. Seventy patients from the Endocrinology and Nephrology Unit at the Hospital Sønderjylland will be included in the intervention and control groups, respectively. The primary outcome is the proportion of potentially inappropriate medications. Secondary outcomes include patient-reported outcomes, i.e., quality of life and medication burden. Additional outcomes include the patient's medication risk score, whether the patient is readmitted, and whether the patient has contacted the staff at the hospital unit after the hospital discharge. The framework for complex intervention is applied, because it allows flexibility and adaption in meeting patients' needs by implementing tailored, possibly complex interventions in different healthcare settings. This project will examine a particular piece in the puzzle of the complexity of conducting a medication review and communication of suggested medication amendments to the patients, healthcare at the hospital, and the GP. Hopefully, this can contribute to a reduction in the risk of potentially inappropriate post-hospital medication usage.

Prevalence and Predictors of Potentially Inappropriate Prescribing in Older People Receiving Home Health Care in Saudi Arabia According to the American Geriatrics Society Beers Criteria 2019

BACKGROUND/OBJECTIVES

Potentially inappropriate prescribing (PIP) is a common health problem in older adults and is associated with negative health outcomes such as the occurrence of adverse drug events. Several studies have been conducted in different countries and settings to assess the prevalence of PIP, including in Home Care Services. However, data on the prevalence of PIP in home-care services in Saudi Arabia are limited. This study aimed to evaluate PIP use among older patients receiving home healthcare services in Saudi Arabia and to identify the predictors and commonly implicated medications.; Methods: A cross-sectional study was conducted over an 8-month period between January and August 2023. Data were collected from the medical records of patients older than 65 years who were currently receiving home health care services at King Faisal Hospital in Taif City, Saudi Arabia. PIPs were identified using the 2019 updated Beers Criteria.; Results: A total of 375 patients were included. Out of these, 285 PIPs were identified, of which 219 patients (58.4%) received at least one PIP. The most common therapeutic class associated with the PIPs was gastrointestinal medications (66.3%). Patient age and number of medications were significant predictors of PIP.; Conclusions: Our study found a high prevalence of PIP among elderly patients receiving home health care in Taif, Saudi Arabia. This study highlights the need for improved patient data automation and implementation of the Beers criteria to prevent PIPs in the future.

Development of explicit definitions of potentially inappropriate prescriptions for antidiabetic drugs in patients with type 2 diabetes: A multidisciplinary qualitative study

PURPOSE

The management of type 2 diabetes mellitus patients has changed over the past decade, and a large number of antidiabetic drug treatment options are now available. This complexity poses challenges for healthcare professionals and may result in potentially inappropriate prescriptions of antidiabetic drugs in patients with type 2 diabetes mellitus which can be limited using screening tools. The effectiveness of explicit tools such as lists of potentially inappropriate prescriptions has been widely demonstrated. The aim was to set up nominal groups of healthcare professionals from several disciplines and develop a list of explicit definition of potentially inappropriate prescriptions of antidiabetic drugs.

METHODS

In a qualitative, nominal-groups approach, 30 diabetologists, general practitioners, and pharmacists in France developed explicit definitions of potentially inappropriate prescriptions of antidiabetic drugs in patients with type 2 diabetes mellitus. A nominal group technique is a structured method that encourages all the participants to contribute and makes it easier to reach an agreement quickly. Each meeting lasted for two hours.

RESULTS

The three nominal groups comprised 14 pharmacists, 10 diabetologists, and 6 general practitioners and generated 89 explicit definitions. These definitions were subsequently merged and validated by the steering committee and nominal group participants, resulting in 38 validated explicit definitions of potentially inappropriate prescriptions of antidiabetic drugs. The definitions encompassed four contexts: (i) the temporary discontinuation of a medication during acute illness (n = 9; 24%), (ii) dose level adjustments (n = 23; 60%), (iii) inappropriate treatment initiation (n = 3; 8%), and (iv) the need for further monitoring in the management of type 2 diabetes mellitus (n = 3; 8%).

CONCLUSION

The results of our qualitative study show that it is possible to develop a specific list of explicit definitions of potentially inappropriate prescriptions of antidiabetic drugs in patients with type 2 diabetes mellitus by gathering the opinions of healthcare professionals caring for these patients. This list of 38 explicit definitions necessitates additional confirmation by expert consensus before use in clinical practice.

Deprescribing interventions in older adults: An overview of systematic reviews

OBJECTIVE

The growing deprescribing field is challenged by a lack of consensus around evidence and knowledge gaps. The objective of this overview of systematic reviews was to summarize the review evidence for deprescribing interventions in older adults.

METHODS

11 databases were searched from 1st January 2005 to 16th March 2023 to identify systematic reviews. We summarized and synthesized the results in two steps. Step 1 summarized results reported by the included reviews (including meta-analyses). Step 2 involved a narrative synthesis of review results by outcome. Outcomes included medication-related outcomes (e.g., medication reduction, medication appropriateness) or twelve other outcomes (e.g., mortality, adverse events). We summarized outcomes according to subgroups (patient characteristics, intervention type and setting) when direct comparisons were available within the reviews. The quality of included reviews was assessed using A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR 2).

RESULTS

We retrieved 3,228 unique citations and assessed 135 full-text articles for eligibility. Forty-eight reviews (encompassing 17 meta-analyses) were included. Thirty-one of the 48 reviews had a general deprescribing focus, 16 focused on specific medication classes or therapeutic categories and one included both. Twelve of 17 reviews meta-analyzed medication-related outcomes (33 outcomes: 25 favored the intervention, 7 found no difference, 1 favored the comparison). The narrative synthesis indicated that most interventions resulted in some evidence of medication reduction while for other outcomes we found primarily no evidence of an effect. Results were mixed for adverse events and few reviews reported adverse drug withdrawal events. Limited information was available for people with dementia, frailty and multimorbidity. All but one review scored low or critically low on quality assessment.

CONCLUSION

Deprescribing interventions likely resulted in medication reduction but evidence on other outcomes, in particular relating to adverse events, or in vulnerable subgroups or settings was limited. Future research should focus on designing studies powered to examine harms, patient-reported outcomes, and effects on vulnerable subgroups.

A mixed methods analysis of the medication review intervention centered around the use of the 'Systematic Tool to Reduce Inappropriate Prescribing' Assistant (STRIPA) in Swiss primary care practices

BACKGROUND

Electronic clinical decision support systems (eCDSS), such as the 'Systematic Tool to Reduce Inappropriate Prescribing' Assistant (STRIPA), have become promising tools for assisting general practitioners (GPs) with conducting medication reviews in older adults. Little is known about how GPs perceive eCDSS-assisted recommendations for pharmacotherapy optimization. The aim of this study was to explore the implementation of a medication review intervention centered around STRIPA in the 'Optimising PharmacoTherapy In the multimorbid elderly in primary CAre' (OPTICA) trial.

METHODS

We used an explanatory mixed methods design combining quantitative and qualitative data. First, quantitative data about the acceptance and implementation of eCDSS-generated recommendations from GPs (n = 21) and their patients (n = 160) in the OPTICA intervention group were collected. Then, semi-structured qualitative interviews were conducted with GPs from the OPTICA intervention group (n = 8), and interview data were analyzed through thematic analysis.

RESULTS

In quantitative findings, GPs reported averages of 13 min spent per patient preparing the eCDSS, 10 min performing medication reviews, and 5 min discussing prescribing recommendations with patients. On average, out of the mean generated 3.7 recommendations (SD=1.8). One recommendation to stop or start a medication was reported to be implemented per patient in the intervention group (SD=1.2). Overall, GPs found the STRIPA useful and acceptable. They particularly appreciated its ability to generate recommendations based on large amounts of patient information. During qualitative interviews, GPs reported the main reasons for limited implementation of STRIPA were related to problems with data sourcing (e.g., incomplete data imports), preparation of the eCDSS (e.g., time expenditure for updating and adapting information), its functionality (e.g., technical problems downloading PDF recommendation reports), and appropriateness of recommendations.

CONCLUSIONS

Qualitative findings help explain the relatively low implementation of recommendations demonstrated by quantitative findings, but also show GPs' overall acceptance of STRIPA. Our results provide crucial insights for adapting STRIPA to make it more suitable for regular use in future primary care settings (e.g., necessity to improve data imports).

Cognitive and functional trajectories in geriatric outpatients after a pharmacologic multidisciplinary intervention: A study protocol

BACKGROUND

Polypharmacy is a common condition among older adults and is associated with adverse drug reactions and health outcomes, including falls, functional and cognitive impairment, and frailty.

METHODS

A prospective observational study will be conducted on older adults with polypharmacy. The aim is to assess the impact of a specialized outpatient clinic focused on pharmacotherapy optimization recently integrated into daily clinical practice in a Spanish public tertiary teaching hospital on patients' functional and cognitive abilities. Patients who attend a first consultation and meet inclusion criteria (≥75 years old, have a life expectancy≥3 months, and polypharmacy (≥5 prescribed medications) will be invited to participate in the study, until reach a calculated sample size of 104 participants. Patients will be excluded if they are enrolled in a clinical trial related to medication or in the event of a no-show or cancellation of the appointment at the first visit. Participants will receive usual care: a first consultation including multidisciplinary pharmacological optimization in the context of a CGA and subsequent face-to-face and/or telephone follow-up (∼3 and ∼6 months). The primary endpoint will be the functional (Barthel index) and cognitive change in capacities (IPCR - Índice de Incapacidad psíquica de la Cruz Roja). Secondary endpoints include medication changes, changes in patients' quality of life, rate of falling, and use of healthcare resources.

DISCUSSION

We expect that the close collaboration between professionals from different disciplines working together will be an effective strategy to improve the functional and cognitive abilities of older adults.

Medication-Related Problems and Their Intervention in the Geriatric Population: A Review of the Literature

In order to implement the principles of providing clinically and economically effective care, the current state of healthcare must be evaluated, and challenges must be addressed. As part of a physician's role in such a context, one tool consists of identifying medication-related problems (MRPs) and accordingly implementing best practices and innovative strategies to improve patient healthcare outcomes. The geriatric population is expected to have passed through the natural ageing process and experienced several physiological and biological changes that impact their bodies and lives. In the presence of geriatric syndromes and the increased number of medications consumed, the risk of MRPs such as polypharmacy, potentially inappropriate medication (PIM), adverse events, drug-drug interactions, and risk of non-adherence increases. Different interventions that focus on practical and perceptual barriers have been studied, and different tools to define clinically important prescribing problems relating to PIM have been established. The Beers Criteria and STOPP (Screening Tool of Older Persons' Prescriptions)/START (Screening Tool to Alert to Right Treatment) criteria are the most widely used sets of explicit PIM criteria; however, they are still limited in Saudi Arabia. These tools should be considered in clinical settings to improve healthcare outcomes in the geriatric population, and the clinical relevance of enhancing medication should also be explored from the point of view of both the patient and healthcare practitioners.

[Spanish version of the STOPP/START 3 criteria: Advances in the detection of inappropriate prescribing medication in the older people]

The STOPP/START criteria are explicit physiologic systems-based criteria that summarize evidence on clinically relevant prescribing problems related to the use of potentially inappropriate medications (STOPP criteria) and potential prescribing omissions (START criteria). The two previous versions of the STOPP/START criteria were published in 2008 and 2015, and their Spanish versions in 2009 and 2015. Version3 of these criteria has just been published in 2023. The aim of this article is to present the Spanish translated version, and to review the use and impact that version2 of 2015 has had in our language. A translation from English to Spanish was performed by expert professionals with a high level of English of version3 of the STOPP/START criteria, which incorporates the evidence published from April 2014 to March 2022. In addition, a systematic review of publications that have used the Spanish translation of the previous version (version2 of 2015) of the STOPP/START criteria was performed. The new version, presented in this article, has 190 STOPP/START criteria (133 STOPP criteria and 57 START criteria), which is a 40% increase in the number of criteria compared to the previous version. The review found 37 studies (21 observational, 11 interventional and 5 other) that used the Spanish version instead of the international version. The Spanish version 3 of the STOPP/START criteria is an updated explicit list of potentially inappropriate medications and possible omissions in prescribing that aims to optimize medication and minimize adverse drug reactions during medication review in the elderly, particularly those with multimorbidity and polypharmacy. With this new version, the original criteria are intended to be more widely disseminated within the Spanish-speaking healthcare community. The Spanish version2 of the STOPP/START has been widely used, so we consider that the translation into Spanish has helped to improve pharmacotherapy in older patients with polypharmacy and multimorbidity in our linguistic environment.

STOPP/START criteria for potentially inappropriate prescribing in older people: version 3

PURPOSE

STOPP/START is a physiological systems-based explicit set of criteria that attempts to define the clinically important prescribing problems relating to potentially inappropriate medications (PIMs-STOPP criteria) and potential prescribing omissions (PPOs-START criteria). The previous two versions of STOPP/START criteria were published in 2008 and 2015. The present study describes the revised and updated third version of the criteria.

METHODS

A detailed system-by-system review of the published literature from April 2014 to March 2022 was undertaken with the aim of including clinically important new explicit PIM and PPO criteria and removing any criteria considered to be no longer correct or outdated. A panel of 11 academic physicians with recognized expertise in geriatric pharmacotherapy from 8 European countries participated in a Delphi panel with the task of validating the draft criteria. The panel was presented with the draft new criteria using the SurveyMonkey® on-line platform in which panelists were asked to indicate their level of agreement on a five-point Likert scale.

RESULTS

Two hundred and four evidence-based draft criteria (one hundred and forty-five STOPP criteria, fifty-nine START criteria) were presented to panelists for assessment using the Delphi validation method. Over the course of four rounds of Delphi validation, the panel achieved consensus on 133 STOPP criteria and 57 START criteria, i.e., 190 STOPP/START criteria in total representing a 66.7% increase in the number of criteria compared to STOPP/START version 2 published in 2015.

CONCLUSION

A fully revised and updated version of STOPP/START criteria has been validated by a European expert panel using the Delphi consensus process.

Potentially inappropriate medications with older people in intensive care and associated factors: a historic cohort study

BACKGROUND

The epidemiology of potentially inappropriate medications (PIMs) in critical care units remains limited, especially in terms of the factors associated with their use.

OBJECTIVE

To estimate the incidence and factors associated with PIMs use in intensive care units.

DESIGN AND SETTING

Historical cohort study was conducted in a high-complexity hospital in Brazil.

METHODS

A retrospective chart review was conducted on 314 patients aged ≥ 60 years who were admitted to intensive care units (ICUs) at a high-complexity hospital in Brazil. The dates were extracted from a "Patient Safety Project" database. A Chi-square test, Student's t-test, and multivariable logistic regression analyses were performed to assess which factors were associated with PIMs. The statistical significance was set at 5%.

RESULTS

According to Beers' criteria, 12.8% of the identified drugs were considered inappropriate for the elderly population. The incidence rate of PIMs use was 45.8%. The most frequently used PIMs were metoclopramide, insulin, antipsychotics, non-steroidal anti-inflammatory drugs, and benzodiazepines. Factors associated with PIMs use were the number of medications (odds ratio [OR] = 1.17), length of hospital stay (OR = 1.07), and excessive potential drug interactions (OR = 2.43).

CONCLUSIONS

Approximately half of the older adults in ICUs received PIM. Patients taking PIMs had a longer length of stay in the ICU, higher numbers of medications, and higher numbers of potential drug interactions. In ICUs, the use of explicit methods combined with clinical judgment can contribute to the safety and quality of medication prescriptions.

Medication Dispensing by Pharmacy Technicians Improves Efficiency and Patient Safety at a Geriatric Ward at a Danish Hospital: A Pilot Study

BACKGROUND

This study aims to evaluate medication dispensing by pharmacy technicians at a geriatric inpatient ward at a Danish hospital.

METHODS

Four pharmacy technicians were trained in delivering a dispensing service at a geriatric ward. At baseline, the ward nurses recorded the time spent dispensing the medication and the number of interruptions. Similar recordings were completed twice during the period in which the pharmacy technicians delivered the dispensing service. Satisfaction among the ward staff with the dispensing service was assessed by a questionnaire. Reported medication errors were collected during the dispensing service period and compared to a similar time period during the previous two years.

RESULTS

The time spent on dispensing medications was on average reduced with 1.4 h per day ranging from 4.7 to 3.3 h per day when the pharmacy technicians performed the service. Interruptions during the dispensing process decreased from a daily average of more than 19 times to an average of 2-3 per day. The nursing staff reported positive feedback on the medication dispensing service provided, especially about easing their workload. There was a tendency toward decreased reporting of medication errors.

CONCLUSION

The medication dispensing service performed by the pharmacy technicians reduced time spent on dispensing medication and increased patient safety by reducing interruptions during the process and decreasing the number of medication errors reported.

Potentially inappropriate medication in long-term care wards of a veteran hospital in Taiwan: Investigation using a spreadsheet-based rapid assessment tool

BACKGROUND

Multimorbidity and polypharmacy increase in the aging population and are accompanied by the use of potentially inappropriate medications (PIMs) and adverse drug events (ADEs). This study developed a rapid assessment tool to investigate PIM use among patients in long-term care wards.

METHODS

We retrospectively collected the data of patients in long-term care wards of a veteran hospital in Taiwan between July 2019 and June 2020. The patients with chronic diseases and medications were selected. The data, including gender, age, diagnosis, and medications, were deidentified. Nonchronic disease diagnosis and short-term and topical use medications were excluded. We used Microsoft Excel (Microsoft Corporation, Redmond, Washington, USA) and the 2019 version of the Beers Criteria to establish a rapid assessment tool. The correlations between the prevalence of PIM use and age, the number of diagnoses, and the number of medications were analyzed using SPSS version 23.

RESULTS

A total of 176 patients were included in this study, of which 76.7% (n = 135) were male and 23.3% (n = 41) were female. The average age of men was 82.1 years and that of women was 83.4 years. The average number of diagnoses for men was 5.5, and that for women was 7.3. The average number of medications for men was 5.8, and that for women was 6.5. The prevalence of PIM use was 59.1% (n = 104). Logistic regression revealed that the prevalence of PIM use may be associated with the number of medications ( p < 0.001; odds ratio = 1.378). Decision tree analysis revealed that patients who simultaneously used more than four medications exhibited a higher risk of PIM.

CONCLUSION

PIM use is a key factor causing ADEs among older adults. Therefore, comprehensive assessment of PIM use is necessary. This study designed a rapid assessment tool to simultaneously integrate and evaluate medications. Future studies may investigate the effectiveness of the proposed assessment tool.

Prevalence of Potentially Inappropriate Prescriptions According to the New STOPP/START Criteria in Nursing Homes: A Systematic Review

The demand for long-term care is expected to increase due to the rising life expectancy and the increased prevalence of long-term illnesses. Nursing home residents are at an increased risk of suffering adverse drug events due to inadequate prescriptions. The main objective of this systematic review is to collect and analyze the prevalence of potentially inadequate prescriptions based on the new version of STOPP/START criteria in this specific population. Databases (PubMed, Web of Science and Cochrane) were searched for inappropriate prescription use in nursing homes according to the second version of STOPP/START criteria. The risk of bias was assessed with the STROBE checklist. A total of 35 articles were assessed for eligibility. One hundred and forty nursing homes and more than 6900 residents were evaluated through the analysis of 13 studies of the last eight years. The reviewed literature returned prevalence ranges between 67.8% and 87.7% according to the STOPP criteria, according to START criteria prevalence ranged from 39.5% to 99.7%. The main factors associated with the presence of inappropriate prescriptions were age, comorbidities, and polypharmacy. These data highlight that, although the STOPP/START criteria were initially developed for community-dwelling older adults, its use in nursing homes may be a starting point to help detect more efficiently inappropriate prescriptions in institutionalized patients. We hope that this review will help to draw attention to the need for medication monitoring systems in this vulnerable population.

Prescription of potentially inappropriate medicines and comparison with lists of essential medicines for treatment of chronic disorders in older patients

OBJECTIVES

To examine the current situation of potentially inappropriate medicines (PIM) for treatment of chronicity in older patients and whether the inappropriate medicines were included in the 22nd World Health Organization (WHO) Model List of Essential Medicines (EMLs), China National Model list of Essential Medicines (China EMLs), or supplementary list of essential medicines in Guizhou Province 2018 (Guizhou EMLs) through real world data, so as to promote the development of lists of essential medicines suitable for older patients and provide a reference for the revision of lists of essential medicines to reduce adverse effects, drug-induced diseases and even possible death due to use of inappropriate medicines existing in lists of essential medicines.

METHODS

A retrospectively study was conducted. Dispensing records of patients aged ≥ 65 admitted to convenience clinic of a tertiary hospital from January 1, 2021 to December 31, 2021 were extracted through electronic information system. Then, we merged dispensing records of the same patient on the same date as one record and patients with at least one chronic disease were included. The American Geriatrics Society(AGS)/Beers Criteria 2019 (Beers 2019) was used to evaluate the PIM status. Thereafter, the inappropriate medicines were compared with WHO EMLs, China EMLs, and Guizhou EMLs to find out percentages of drugs of PIMs existing in above lists of essential medicines in all drugs of PIMs. The above evaluation was conducted using Excel software (version 2019).

RESULTS

A total of 5314 dispensing reports were included in this study. 5.95% (316/5314), 7.88% (419/5314) of PIMs met Table 2 (medicines that are potentially inappropriate in most older adults), Table 4 (medicines that should be used with caution) of Beers 2019, respectively. Among PIM drugs which met Table 2 of Beers 2019, 47.37%, 78.95%, and 78.95% were respectively included in WHO EMLs, China EMLs, and Guizhou EMLs, and that was 47.06%, 76.47%, and 82.35% for Table 4 of Beers 2019.

CONCLUSIONS

PIM in older patients is common in clinical practice. Patients with diabetes, hypertension, arthritis, depression and/or anxiety and Parkinson' diseases were more frequently prescribed drugs of PIM according to Beers 2019. Take older patients into consideration and formulate List of essential medicines special for older patients may be a key way to reduce PIM.

Detectability of Medication Errors With a STOPP/START-Based Medication Review in Older People Prior to a Potentially Preventable Drug-Related Hospital Admission

INTRODUCTION

Multimorbidity and polypharmacy are risk factors for drug-related hospital admissions (DRAs) in the ageing population. DRAs caused by medication errors (MEs) are considered potentially preventable. The STOPP/START criteria were developed to detect potential MEs in older people.

OBJECTIVE

The aim of this study was to assess the detectability of MEs with a STOPP/START-based in-hospital medication review in older people with polypharmacy and multimorbidity prior to a potentially preventable DRA.

METHODS

Hospitalised older patients (n = 963) with polypharmacy and multimorbidity from the intervention arm of the OPERAM trial received a STOPP/START-based in-hospital medication review by a pharmacotherapy team. Readmissions within 1 year after the in-hospital medication review were adjudicated for drug-relatedness. A retrospective assessment was performed to determine whether MEs identified at the first DRA were detectable during the in-hospital medication review.

RESULTS

In total, 84 of 963 OPERAM intervention patients (8.7%) were readmitted with a potentially preventable DRA, of which 72 patients (n = 77 MEs) were eligible for analysis. About half (48%, n = 37/77) of the MEs were not present during the in-hospital medication review and therefore were not detectable at that time. The pharmacotherapy team recommended a change in medication regimen in 50% (n = 20/40) of present MEs, which corresponds to 26% (n = 20/77) of the total identified MEs at readmission. However, these recommendations were not implemented.

CONCLUSION

MEs identified at readmission were not addressed by a prior single in-hospital medication review because either these MEs occurred after the medication review (~50%), or no recommendation was given during the medication review (~25%), or the recommendation was not implemented (~25%). Future research should focus on optimisation of the timing and frequency of medication review and the implementation of proposed medication recommendations.

Factors Influencing Self-Reported Medication Use in the Survey of Health Aging and Retirement in Europe (SHARE) Dataset

The validity of self-reported medication use in epidemiological studies is an important issue in healthcare research. Here we investigated factors influencing self-reported medication use for multiple diagnoses in the seventh wave of the Survey of Health Aging and Retirement in Europe (SHARE) dataset in n = 77,261 participants (ages: mean = 68.47, standard deviation = 10.03 years). The influence of mental, physical, and sociodemographic parameters on medication self-report was analyzed with logistic regressions and mediation models. Depression, memory function, and polypharmacy influenced the self-report of medication use in distinct disorders to varying degrees. In addition, sociodemographic factors, knowledge about diagnosis, the presence of several chronic illnesses, and restrictions of daily instrumental activities explained the largest proportion of variance. In the mediation model, polypharmacy had an indirect effect via depression and memory on self-reported medication use. Factors influencing medication self-report vary between different diagnoses, highlighting the complexity of medication knowledge. Therefore, it is essential to assess the individual parameters and their effect on medication behavior. Relying solely on medication self-reports is insufficient, as there is no way to gage their reliability. Thus, self-reported medication intake should be used with caution to indicate the actual medication knowledge and use.
