Potentially inappropriate medication prescribing based on 2019 Beers criteria and the impact of pharmacist intervention in elderly patients with kidney diseases: A report from Iran

Background and Aims

A potentially inappropriate medication (PIM) is a pharmaceutical agent that poses a greater risk of harm than potential benefit to elderly patients. This study aimed to detect PIMs and their risk factors in hospitalized elderly patients with kidney disease.

Methods

This cross-sectional study assessed medication orders of elderly patients (≥65 years old) with kidney diseases admitted to the hospital. In the first 6 months, we retrospectively evaluated all medications to identify PIMs according to the 2019 Beers criteria. In the second phase, a clinical pharmacist prospectively evaluated all medications and suggested modifications as needed. Data were analyzed to determine risk factors for prescribing PIMs.

Results

Based on our evaluation of 258 patients, we observed that the utilization of PIMs was prevalent among the study population. Of the total patients evaluated, 273 instances of PIM use were identified, with only 23.3% of patients not having any PIMs. Notably, proton pump inhibitors and benzodiazepines were the most frequently prescribed PIMs. The risk of experiencing a PIM was significantly amplified by a higher degree of polypharmacy, with odds approximately 2.68 times higher (p < 0.01). Several factors were found to be associated with an increased likelihood of having a PIM, including being male, undergoing hemodialysis, having chronic kidney disease or other comorbidities, and having an extended hospital stay. The second phase of study, in terms of addressing these issues, physicians adhered to 67.5% of the 120 recommendations made by pharmacists regarding the discontinuation of PIM usage.

Conclusion

High prevalence of PIMs was detected in our study population. Preventing medication-associated harms in the elderly can reduce the financial burden imposed on healthcare systems. Therefore, routine evaluation of medications with clinical pharmacists and/or implementation of computerized medication decision support systems is recommended to prevent PIMs use.

Prevalence and determinants of potentially inappropriate medications in elderly inpatients in Thailand: a retrospective observational study based on the 2019 Beers criteria

Background

The prevalence of potentially inappropriate medications (PIMs), including NSAIDs, first-generation antihistamines, tricyclic antidepressants (TCAs), and benzodiazepines among elderly inpatients in Thailand, based on the 2019 Beers criteria, is insufficiently investigated.

Methods

This study retrospectively examined 300 elderly patients in a Thai tertiary hospital, assessing four PIM classes based on the 2019 Beers criteria and exploring factors and variations in PIM prescription patterns across different phases of hospitalisation.

Results

The study found an overall PIM prescription rate of 28%, consisting of: benzodiazepines (14%), first-generation antihistamines (9%), NSAIDs (3%), and TCAs (2%). Patients taking at least 5 medications prior to admission were more likely to receive PIMs (OR 3.77, 95% CI 1.15-12.35). Furthermore, PIM prescription was significantly associated with age, showing a 4.8% yearly increase (p = 0.01), and the number of comorbidities increased by 16.2% per unit (p = 0.021). Additionally, PIM use during admission was significantly linked to a longer hospital stay (OR 3.32, 95% CI 1.50-7.33).

Conclusions

These findings emphasise the need for continued monitoring and optimisation of medication management, and collaboration between pharmacists and physicians to review and adjust prescriptions, especially in elderly inpatients experiencing polypharmacy and multiple comorbidities.

Evaluation of potentially inappropriate medications use and medication complexity in elderly patients applying to community pharmacy in Turkey

BACKGROUND

Older adults often use multiple medicines to manage comorbidities well or to prevent associated complications. This study aims to determine polypharmacy, the use of potentially inappropriate medications (PIMs) using the 2019 Beers Criteria and to determine the Medication Regimen Complexity Index (MRCI) score. It also aims to identify factors associated with the presence of PIMs and the MRCI score.

METHODS

This cross-sectional study was carried out between 6 and 2023 and 5 May 2023 in a community pharmacy in Turkey. Elderly patients over 65 years of age, who used at least one drug, and who came to the pharmacy for any reason were included in the study. PIMs were determined according to the 2019 Beers Criteria. The Turkish validated version of the MRCI was used to determine the medication complexity score.

RESULTS

200 patients were included in this study. 59.5% of the patients were female and the median age was 70 (IQR, 66-74.75). Polypharmacy was detected in 33% of patients. The use of PIMs was determined in 63.5% of the patients. The median of the MRCI score was 11 (IQR, 7-15). The number of chronic diseases and drugs, presence of polypharmacy, MRCI score and mental disorders were found to be significantly higher in those with PIMs than in those without (p < 0.05). Having less than eight years of education, presence of polypharmacy, the presence of comorbidity (diabetes mellitus, cardiovascular disease, thyroid, chronic obstructive pulmonary disease (COPD), asthma and mental disorders) were associated with significantly higher MRCI scores (p < 0.05).

CONCLUSIONS

According to the results of our study, it was found that the elderly patients who came to the pharmacy had low MRCI scores, but had high PIMs use. Community pharmacists have an important role in identifying inappropriate drug use, so they should be trained to develop skills in identifying and reducing PIMs in older patients.

Using PIM-Taiwan, PRISCUS, and Beers criteria to assess potentially inappropriate medication use among older adults with 90-day rehospitalization: a population-based study in Taiwan

Background: Multimorbidity and polypharmacy increase the risk of hospitalization in older adults receiving potentially inappropriate medication (PIM). The current study compared the ability of PIM-Taiwan, PRISCUS, and Beers criteria to predict 90-day rehospitalization in older patients with and without PIM. Methods: The retrospective cohort study used Taiwan's Longitudinal Health Insurance Database to retrieve quarterly information about prescribed medication for adults aged ≥65 years hospitalized between 2001 and 2018. We analyzed the association of PIM with 90-day rehospitalization using logistic regression. Results: The study cohort included 206,058 older adults (mean age: 72.5 years). In the analysis, 133,201 (64.6%), 97,790 (47.5%), and 147,450 (71.6%), were identified as having PIM exposure in PIM-Taiwan, PRICUS, and Beers criteria, respectively. PIM-Taiwan criteria found exposure to PIM affecting the cardiovascular (adjusted OR [aOR] 1.37, 95% confidence interval [CI] = 1.32-1.41), gastrointestinal (aOR 1.26, 95% CI = 1.23-1.30), central nervous (aOR 1.11, 95% CI = 1.08-1.14), and respiratory (aOR 1.16, 95% CI = 1.12-1.20) systems significantly increased the risk of 90-day rehospitalization, after adjustment for covariates. In PRISCUS criteria, exposure to PIM affecting the respiratory (aOR 1.48, 95% CI = 1.41-1.56), central nervous (aOR 1.12, 95% CI = 1.09-1.15), and cardiovascular (aOR 1.20, 95% CI = 1.16-1.24) systems significantly increased the risk. In Beers criteria, exposure to PIM affecting the cardiovascular (aOR 1.37, 95% CI = 1.32-1.41), gastrointestinal (aOR 1.38, 95% CI = 1.35-1.42), central nervous (aOR 1.18, 95% CI = 1.15-1.21), endocrine (aOR 1.10, 95% CI = 1.06-1.15), and respiratory (aOR 1.09, 95% CI = 1.04-1.13) systems significantly increased the risk. Patients with 90-day rehospitalization had higher rates of the potentially harmful drug-drug interaction (DDI) pairs of serotonin syndrome (n = 19; 48.8%), QT prolongation (n = 4; 30.8%), extrapyramidal symptoms (EPS) (n = 102; 24.5%), and hypokalemia (n = 275; 20.1%). Conclusion: Beers criteria was more efficient in predicting 90-day rehospitalization among older adults experiencing PIM in Taiwan than either PIM-Taiwan or PRISCUS. The risk of 90-day rehospitalization was associated with the potentially harmful DDI classes of serotonin syndrome, QT prolongation, EPS, and hypokalemia.

American Geriatrics Society 2023 updated AGS Beers Criteria® for potentially inappropriate medication use in older adults

The American Geriatrics Society (AGS) Beers Criteria® (AGS Beers Criteria®) for Potentially Inappropriate Medication (PIM) Use in Older Adults is widely used by clinicians, educators, researchers, healthcare administrators, and regulators. Since 2011, the AGS has been the steward of the criteria and has produced updates on a regular cycle. The AGS Beers Criteria® is an explicit list of PIMs that are typically best avoided by older adults in most circumstances or under specific situations, such as in certain diseases or conditions. For the 2023 update, an interprofessional expert panel reviewed the evidence published since the last update (2019) and based on a structured assessment process approved a number of important changes including the addition of new criteria, modification of existing criteria, and formatting changes to enhance usability. The criteria are intended to be applied to adults 65 years old and older in all ambulatory, acute, and institutionalized settings of care, except hospice and end-of-life care settings. Although the AGS Beers Criteria® may be used internationally, it is specifically designed for use in the United States and there may be additional considerations for certain drugs in specific countries. Whenever and wherever used, the AGS Beers Criteria® should be applied thoughtfully and in a manner that supports, rather than replaces, shared clinical decision-making.

Anticholinergic exposure and its association with dementia/Alzheimer's disease and mortality in older adults

BACKGROUND

Use of anticholinergic (ACH) medications is associated with increased risk of cognitive decline in the elderly. However, little is known about this association from a health plan perspective.

METHODS

This retrospective cohort study used the Humana Research Database to identify individuals with at least one ACH medication dispensed in 2015. Patients were followed until incidence of dementia/Alzheimer's disease, death, disenrollment or end of December 2019. Multivariate Cox regression models were used to assess the association between ACH exposure and study outcomes, adjusting for demographics and clinical characteristics.

RESULTS

A total of 12,209 individuals with no prior ACH use or dementia/Alzheimer's disease diagnosis were included. As ACH polypharmacy increased (i.e., from no ACH exposure, to one, two, three, and four or more ACH medications), there was a stair-step increase in the incidence rate of dementia/Alzheimer's disease (15, 30, 46, 56 and 77 per 1,000 person-years of follow-up) and in the incidence of mortality (19, 37, 80, 115 and 159 per 1,000 person-years of follow-up). After adjusting for confounders, ACH exposure to one, two, three and four or more ACH medications was associated with a 1.6 (95% CI 1.4-1.9), 2.1 (95% CI 1.7-2.8), 2.6 (95% CI 1.5-4.4), and 2.6 (95% CI 1.1-6.3) times, respectively, increased risk of a dementia/Alzheimer's disease diagnosis compared to periods of no ACH exposure. ACH exposure to one, two, three and four or more medications was associated with a 1.4 (95% CI 1.2-1.6), 2.6 (95% CI 2.1-3.3), 3.8 (95% CI 2.6-5.4), and 3.4 (95% CI 1.8-6.4) times, respectively, increased risk of mortality compared to periods of no ACH exposure.

CONCLUSIONS

Reducing ACH exposure may potentially minimize long-term adverse effects in older adults. Results suggest populations which may benefit from targeted interventions to reduce ACH polypharmacy.

Inappropriate Medications Use and Polypharmacy among Older Adults with Anxiety Disorder

BACKGROUND

Elderly with mental health conditions usually use multiple medications, which predisposes them to inappropriate use of medications, which is defined as medications that should be avoided due to their risk; this outweighs their benefit given that safer alternatives are available. This study aimed to examine potentially inappropriate medication use among older patients with anxiety disorder.

METHODS

This study used a cross-sectional retrospective study design using twelve months of data extracted from the Electronic Health Record (EHR) database for older adults diagnosed with anxiety disorder and treated in the ambulatory care setting. Potentially inappropriate medications (PIMs) use was evaluated using the 2019 Beers criteria. Descriptive statistics were used to describe the sample. Pearson's chi-square tests (for categorical variables) and t-tests (for continuous variables) were utilized to measure the differences in independent variables between patients with and without PIMs. Binary logistic regression was used to examine the associations between PIMs use and identify potential factors for PIMs use among older adults with anxiety disorder. Analyses were performed using the Statistical Analysis Software version 9.4 (SAS^® 9.4).

RESULTS

The study sample includes 371 older adults (age ≥ 65 years) with anxiety disorder; their average age was (72.1 ± 5.8) years. PIMs use was highly prevalent among older adults with anxiety (66.6%). About 35.6% of the study sample used one PIM, 22.6% used two PIMs, and 8.4% used three PIMs. The most frequently prescribed PIMs were NSAIDs and gastrointestinal agents. The adjusted regression analysis found that PIMs use was less likely among men than women. In addition, PIMs use was more likely among women with diabetes, cancer, and polypharmacy.

CONCLUSIONS

Future studies on strategies and interventions rationing PIMs use in older adults with anxiety disorder are necessary given the high prevalence of PIMs and polypharmacy within this population.

Potentially Inappropriate Medications Use among Older Adults with Dyslipidaemia

BACKGROUND

Since older patients with dyslipidemia frequently receive many prescriptions, medication errors are typical and expected in this population. This risk has increased by using potentially inappropriate medications. The 2019 Beers criteria were used in this study to investigate potentially inappropriate medication use among older individuals with dyslipidemia.

METHODS

A cross-sectional retrospective analysis used data from electronic medical records from an ambulatory-care environment. Patients with dyslipidemia who were older adults (>65 years old) were included. To describe and find potential determinants of potentially inappropriate medication usage, descriptive statistics and logistic regression were employed.

RESULTS

This study included 2209 older adults (age ≥ 65) with dyslipidemia. The mean age was 72.1 ± 6.0 years, and the majority of the study sample had hypertension (83.7%) and diabetes (61.7%), and around 80.0% were using polypharmacy. The prevalence of potentially inappropriate medications to be avoided among older adults with dyslipidemia was 48.6%. A high risk of potentially inappropriate medication usage was found in older patients with dyslipidemia who had polypharmacy and comorbid diabetes, ischemic heart disease, and anxiety.

CONCLUSIONS

This study showed that the number of medications prescribed and the presence of concurrent chronic health conditions are important indicators of the risk of potentially inappropriate medications in ambulatory older patients with dyslipidemia.

Gender Differences in Potentially Inappropriate Medication Use among Older Adults

BACKGROUND

Use of potentially inappropriate medication (PIMs) is a prominent concern that leads to significant medication-related issues among older adults. Notably, older women tend to utilize more medicines than men; older women frequently take more drugs. In addition, some evidence suggests that prescription PIMs vary by gender. This study examines the gender-based variation in prescribing PIM among older adults in Saudi Arabia.

METHODS

A cross-sectional retrospective analysis of electronic medical records from a large hospital in Saudi Arabia was carried out. Patients over the age of 65 who received ambulatory treatment were included in the study. The utilization of PIM was assessed based on Beers criteria. Descriptive statistics and logistic regression were employed to describe patterns of PIM utilization and identify factors associated with their use. All statistical analyses were performed using Version 9.4 of the Statistical Analysis Software (SAS^® 9.4).

RESULTS

The study comprised 4062 older people (age 65) who visited ambulatory care clinics; the average age was (72.6 ± 6.2) years. The majority of the study sample was women (56.8%). Among older adults, 44.7% of older men and 58.3% of older women reported having PIMs that should be avoided, indicating a higher prevalence of PIMs among women compared to men. In terms of the PIM categories used, women had a much higher utilization rate of cardiovascular and gastrointestinal drugs than men. In men, the use of PIMs was frequently associated with hypertension, ischemic heart disease, asthma, osteoarthritis, and cancer, while in women PIM use was associated with age, dyslipidemia, chronic kidney disease, and osteoporosis.

CONCLUSIONS

This study revealed sex differences in PIM prescribing among older adults; PIM use is more common among women. Sex differences exist in clinical and socioeconomic characteristics and factors related to using potentially inappropriate medications. This study revealed essential areas that could be targeted by further interventions to improve drug-prescribing practices among older adults at risk of PIM.

Assessing medication use quality in older outpatients using the Beers criteria: findings from a single-center retrospective study

Background

No comprehensive assessment of the quality of medications used in older outpatients has been conducted in Thailand. This study aimed to ascertain the prevalence of and factors contributing to older outpatients' use of potentially inappropriate medications (PIMs).

Methods

This cross-sectional study retrospectively assessed the prescriptions of older (60 years) outpatients at a secondary-care hospital. For PIM identification, the 2019 American Geriatric Society (AGS) Beers criteria were applied, considering all five PIM categories: PIM category I (medications that are potentially inappropriate in most older adults), II (disease-/syndrome-exacerbating drugs), III (medications that should be used with caution), IV (clinically important drug-drug interactions), and V (medications that should be avoided or have their dosage reduced based on renal function).

Results

This study included 22,099 patients (mean age = 68.86 ± 7.64 years). Nearly three-fourths of patients were prescribed PIMs, with 68.90%, 7.68%, 44.23%, 15.66%, and 3.05%, respectively, receiving category I-V medications. The positive factors associated with PIM use included female sex (odds ratio [OR] = 1.08, 95% confidence interval [CI] = 1.01-1.16), age 75 years (OR = 1.10, 95% CI = 1.01-1.21), polypharmacy (OR = 10.21, 95% CI = 9.31-11.21), 3 diagnostic categories (OR = 2.31, 95% CI = 2.14-2.50), and 3 chronic morbidities (OR = 1.46, 95% CI = 1.26-1.68). The negative factor associated with PIM use was a comorbidity score of 1 (OR = 0.78, 95% CI = 0.71-0.86).

Conclusion

PIM use among older outpatients remains highly prevalent in clinical practice. The results of this study identified polypharmacy as the strongest factor affecting PIM use.

Potentially inappropriate medications use in a psychiatric elderly care hospital: A cross-sectional study using Beers criteria

Background and Aims

Potentially inappropriate medications (PIMs) carry risks that outweigh any potential benefits when compared to safer or more effective alternative treatments. Adverse drug events are more likely to occur in older adults with psychiatric diseases due to multimorbidity, polypharmacy, and age-related changes in drug pharmacokinetics and pharmacodynamics. The aim of this study was to assess the prevalence and risk factors of PIM use in an aged care hospital's psychogeriatric division, using the American Geriatrics Society Beers criteria 2019.

Methods

This cross-sectional study was conducted on all current inpatients, having a mental disorder and aged ≥65 years, in one elderly care hospital in Beirut, from March to May 2022. Medications, sociodemographic and clinical characteristics were collected from patients' medical records. PIMs were evaluated based on Beers criteria 2019. Independent variables were described using descriptive statistics. Factors associated with PIM use were identified by bivariate analysis followed by binary logistic regression. A two-sided p value <0.05 was considered statistically significant.

Results

The study included 147 patients, with a mean age of 76.3 years, 46.9% of them having schizophrenia, 68.7% using 5 or more drugs and 90.5% taking at least 1 PIM. The most prescribed PIMs were antipsychotics (40.2%), anticholinergics (16%), and antidepressants (7.8%). PIM use was significantly associated with polypharmacy (AOR = 20.88, 95% CI: 1.22-357.87, p = 0.04) and anticholinergic cognitive burden (ACB) score (AOR = 7.25, 95% CI: 1.13-46.52, p = 0.04).

Conclusion

PIMs were highly prevalent among hospitalized Lebanese psychiatric elderly. Polypharmacy and ACB score were the determinants of PIM use. A multidisciplinary medication review led by a clinical pharmacist could reduce PIM use.

Potentially Inappropriate Medication at Admission and at Discharge: A Geriatric Study in an Internal Medicine Service in Portugal

Aging is associated with an increase in the prevalence of chronic diseases and polypharmacy, and with the prescription of potentially inappropriate medications (PIMs). This study aimed to analyze the variation in PIMs from hospital admission to discharge. A retrospective cohort study was conducted on inpatients of an internal medicine service. According to the Beers criteria, 80.7% of the patients had been prescribed at least one PIM at admission and 87.2% at discharge; metoclopramide was the most-prescribed PIM from admission to discharge, and acetylsalicylic acid was the most-deprescribed one. According to the STOPP criteria, 49.4% of patients had been prescribed at least one PIM at admission and 62.2% at discharge; quetiapine was the most-prescribed PIM from admission to discharge, and captopril was the most-deprescribed one. According to the EU(7)-PIM list, 51.3% of patients had been prescribed at least one PIM at admission and 70.3% at discharge, and bisacodyl was the most-prescribed PIM from admission to discharge and propranolol the most-deprescribed one. It was found that the number of PIMs at discharge was higher than at admission, suggesting the need to develop a guide with adapted criteria to be applied in an internal medicine service.

Medication-Related Acute Care Admission and Inappropriate Polypharmacy of Nursing Home Residents

OBJECTIVES

To evaluate the prevalence of medication-related admissions (MRAs) and their association with potentially inappropriate medications (PIMs) used by nursing home residents admitted to the geriatric center of a tertiary hospital.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Older patients admitted from nursing homes to the geriatric center of the Seoul National University Bundang Hospital who had undergone comprehensive geriatric assessment from January 1, 2016, to December 31, 2020.

METHODS

MRAs were determined and verified using a previously described MRA adjudication guide. The PIMs in the preadmission medication lists were identified according to each of the following criteria (as well as the combined criteria), the Beers, NORGEP-NH, STOPP/START-NH, and STOPPFrail criteria. Medication use factors associated with MRAs were analyzed using multivariate logistic regression.

RESULTS

Among the 304 acute care admissions, 32.2% were MRAs. The main cause of MRAs was acute kidney injury related with use of renin-angiotensin system inhibitors. Approximately 81% of the patients used at least 1 PIM according to the combined criteria. The use of 1 or more PIMs, renin-angiotensin system inhibitors, diuretics, nonsteroidal anti-inflammatory drugs, and benzodiazepines was significantly associated with MRAs. The combined criteria were able to predict MRAs better than the individual criteria.

CONCLUSIONS AND IMPLICATIONS

Approximately one-third of acute admissions of nursing home residents may be MRAs. Interventions for the optimal use of medication among nursing home residents are needed.

Knowledge, attitude, and practice of medical interns and postgraduate residents on American Geriatric Society updated Beers criteria

BACKGROUND

Potentially inappropriate medication (PIM) prevalence in older adults is increasing day by day due to lack of knowledge among medical students and professionals.

OBJECTIVE

To determine the knowledge of medical students toward American Geriatric Society (AGS) Beers criteria for PIM prescribing.

MATERIALS AND METHODS

This cross-sectional study employed a self-administered questionnaire which was validated and designed to assess the knowledge, attitude, and practice of medical interns and postgraduate residents on Beers criteria for PIMs in older adults. The study was conducted in Faridkot region of Punjab in 2019. This study will utilize a purposive sampling strategy and a convenience sampling of up to 183 participants. Mann-Whitney U or Kruskal-Wallis tests were used to compare different issues as appropriate. P values of <0.05 were considered significant.

RESULTS

Out of 183 questionnaires distributed, only 155 participants (response rate 84.6%) had filled the survey and were included in the study. 61.3% (n = 95) of the respondents were males. The mean knowledge score of 155 participants was (5.16 ± 1.56), where the highest score was 9 and the lowest score was 2 out of 10. 15.5% (n = 24) of the participant strongly agreed that Beers criteria use is necessary in clinical setting and would be very helpful. While 22.5% (n = 35) of the participants strongly agreed that PIMs cause adverse drug event (ADE) and drug-related problems (DRPs) in older adults. Age of the participant had a significant effect on the knowledge score (p = 0.009), and participant aged between 31 and 40 years had significantly higher knowledge scores compared with participants falls under 20-30 years.

CONCLUSION

Medical students and postgraduate residents had average knowledge of PIMs and are unaware of the standard guidelines in older adults such as the Beers criteria. Lack of formal education or training about Beers guidelines was the main reason responsible for average knowledge among participants.

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.

Assessment of Knowledge, Attitude and Practices of the Hospital and Community Pharmacists in Saudi Arabia (Jeddah) towards Inappropriate Medication Use in Older Adults

In Saudi Arabia, the older adult population is growing and is projected to increase three-fold by 2030. Potentially inappropriate medications (PIMs) are harmful to older adults' and have a direct impact on clinical, health and economic outcomes. Pharmacists have a vital role in medication tailoring for older adults as multidisciplinary team members. However, there is also a paucity of research regarding pharmacists' participation in detecting and avoiding PIMs use among older adults in Saudi Arabia. A cross-sectional, self-administered survey was conducted to assess the knowledge, practices, and attitude of pharmacists from seven hospitals and ten community pharmacies in Jeddah, Saudi Arabia. The survey comprised three sections; (i) identifying participants' general characteristics, (ii) assessing their knowledge of PIMs use in older adults and (iii) examining the pharmacist's attitude towards the procedures followed in dispensing for older adults. Inferential and descriptive statistics were used to analyse the survey data. A total of 157 community and hospital pharmacists participated in this study. Most of them dispensed medication weekly to older adults (85.4%), and 43.3% had relevant work experience of six to ten years. Though 44.6% of the participants were aware of PIMs that older adults should avoid, only 10.8% claimed adequate knowledge about PIMs. From the given three clinical case scenarios, a minority of pharmacists (21.7%) chose the correct answers, with a mean score of 2.38 ± 2.91 (95% CI 2.35-3.15). Participants who claimed to have knowledge of PIMs had a significantly higher mean score than those who did not, 4.59 ± 2.81 25 (95% CI 2.35-2.61). A minority of the pharmacists (14.7%) used screening tools such as STOPP, Beers criteria, or Medication Appropriateness Index (MAI) to detect PIMs in older adults. No statistically significant differences were detected when comparing the levels of knowledge of pharmacists with 1 to 5 years of practice to pharmacists with 6 to 15 and more years of experience (p = 0.431). Pharmacists' knowledge, attitude and practices toward PIMs use in older adults in Saudi Arabia should be improved. The application of PIMs detection tools such as STOPP/START or Beers criteria currently has no place in day-to-day pharmacists' roles in Saudi Arabia. Therefore, concerned stakeholders should develop educational programs to improve pharmacists' knowledge of PIMs and promote the effective use of PIM screening tools such as Beers and STOPP criteria in their practice.

Potentially inappropriate medication use in the elderly: physicians' and hospital pharmacists knowledge, practice, confidence, and barriers

BACKGROUND

Inappropriate medication prescribing and dispensing by physicians and pharmacists is a preventable cause of morbidity and mortality in the elderly. Signifying the importance of healthcare professionals' knowledge of potentially inappropriate prescribing tools/ guidelines which would improve overall health outcomes. Beers Criteria is one of the most used guidelines that list specific potentially inappropriate medications (PIMs). This study aimed to investigate physicians' and hospital pharmacists' awareness, knowledge, practice, confidence, and barriers to the use of Beers criteria.

METHODS

A cross-sectional survey was carried out among 66 hospital pharmacists and 31 family medicine physicians working in a teaching hospital in Nigeria, between May and September 2021 using a self-administered questionnaire. Knowledge of PIMs was assessed using 11 clinical vignettes based on the 2019 Beers Criteria. Practice behavior towards elderly patients was assessed using a 5-item statement with a 5-point Likert scale. Perceived barriers to the appropriate use of Beers Criteria were assessed using a 15-item statement. Descriptive and inferential statistics were used to analyze the data.

RESULTS

A total of 66 hospital pharmacists and 31 family medicine physicians participated in the study. Only (24; 36.4%) pharmacists and (4; 12.9%) physicians knew guidelines that listed specific PIMs. In all (21; 31.8%) pharmacists and (11; 35.4%) physicians demonstrated good knowledge of Beers Criteria, while most pharmacists (55; 83.3%) and physicians (29; 93.5%) reported good practice when dealing with elderly patients in terms of asking relevant questions and considering their ages while dispensing medications. Knowledge scores were not significantly associated with hospital pharmacists' socio-demographics. Most of the physicians and pharmacists were confident in the care provided for geriatric patients. The majority (66; 100.0%) pharmacists and (28; 93.5%) physicians suggested training through seminar presentations as a measure to improve the use of Beers' criteria. Lack of time to counsel patients was a major barrier recounted by both physicians and pharmacists.

CONCLUSION

Healthcare professionals that participated in this study had satisfactory practice, although a gap in the knowledge of hospital pharmacists and family medicine physicians was noted. In addition to creating awareness among healthcare professionals and training on PIMs and Beers' criteria, a multidisciplinary approach to reduce potentially inappropriate prescribing and dispensing would greatly help reduce the incidence of potentially inappropriate medication use among elderly patients.

Evaluation of potentially inappropriate medications in older patients admitted to the cardiac intensive care unit according to the 2019 Beers criteria, STOPP criteria version 2 and Chinese criteria

WHAT IS KNOWN AND OBJECTIVES

Potential inappropriate medications (PIMs) can increase the risk of medication-induced harm. However, there are no studies regarding PIMs in older and critically ill patients with cardiovascular diseases in China. Therefore, studies evaluating PIMs in these patients can help in the implementation of more effective interventions to reduce the risk of drug use. Our objective was to analyse the prevalence of PIMs in elderly patients admitted to the cardiac intensive care unit (CICU) comparing the 2019 Beers criteria (Beers criteria), Screening Tool of Older People's Potentially Inappropriate Prescriptions (STOPP) criteria version 2 (STOPP criteria) and criteria of potentially inappropriate medications for older adults in China (Chinese criteria); and analyse the factors influencing the PIMs.

METHODS

This cross-sectional and retrospective study was performed with elderly patients (≥65 years) admitted to the CICU of the Beijing Tongren Hospital in China from January 2019 to June 2020. The PIMs were identified based on the Chinese, STOPP and Beers criteria at admission and discharge. The three criteria were compared using the Kappa statistic. Multiple regression analysis was used to investigate the influencing factors associated with PIMs.

RESULTS AND DISCUSSION

A total of 369 patients who met the inclusion/exclusion criteria were included in this study. According to the three criteria used to evaluate the PIMs, the prevalence was 78.3% and 72.6% at admission and discharge, respectively. The prevalence rate of PIMs determined by the Chinese criteria was 62.1% at admission versus 56.6% at discharge (p = 0.134); the Beers criteria was 53.9% at admission versus 46.9% at discharge (p = 0.056); by the STOPP criteria was 20.6% at admission versus 13.8% at discharge (p = 0.015). Moreover, 28.9% (STOPP criteria), 56.8% (Beers criteria) and 73.4% (Chinese criteria) of patients taking PIMs on admission still had the same problem at discharge. The most common PIMs screened by the Beers, STOPP and Chinese criteria were diuretics, benzodiazepines and clopidogrel, respectively. Besides, the three criteria showed poor agreement. Finally, the stronger predictor of PIMs was the increased number of medications (p < 0.05).

WHAT IS NEW AND CONCLUSION

The prevalence of PIMs in elderly patients admitted to the CICU was high. The Chinese, STOPP and Beers criteria are effective screening tools to detect PIMs, but the consistency between them was poor. The increased number of medications was a significant predictor of PIMs.

Potentially Inappropriate Medication Use in Patients with Dementia

The objective of this study was to characterize the epidemiology of using potentially inappropriate medications associated with dementia exacerbation (DPIMs) in elderly outpatients with dementia. Electronic medical records were retrospectively reviewed for geriatric patients with dementia who were prescribed at least one medication in 2016 at a tertiary, university-affiliated hospital. The 2015 Beers criteria were used to define DPIMs. Logistic regression was performed to identify factors associated with prescribing DPIMs in patients with dementia. Among 2100 patients included in our study, 987 (47.0%) patients were prescribed at least one DPIM. Benzodiazepines were the most frequently prescribed DPIM followed by anticholinergics, histamine H2-receptor blockers, and zolpidem. The risk of prescribing DPIMs was significantly increased in female patients (odds ratio (OR) 1.355) with polypharmacy (OR 5.146) and multiple comorbidities (OR 1.129) (p < 0.05 for all). Coexistence of Parkinson's disease (OR 1.799), mood disorder (OR 1.373), or schizophrenia (OR 4.116) in patients with dementia further increased the likelihood of receiving DPIMs. In conclusion, DPIMs were commonly used in elderly patients with dementia in Korea with benzodiazepines most frequently prescribed followed by anticholinergics. Female patients using polypharmacy with multiple comorbidities should be closely monitored to minimize unnecessary DPIM use and, ultimately, DPIM-related harms.

Polypharmacy and potentially inappropriate medications in stroke rehabilitation: prevalence and association with outcomes

Background Evidence is scarce regarding polypharmacy and potentially inappropriate medications (PIMs) in rehabilitation medicine. Aim To investigate the prevalence of polypharmacy and PIMs and their association with outcomes in stroke rehabilitation. Method A retrospective cohort study was conducted with 849 older inpatients post-stroke. Polypharmacy was defined as six or more medications, and PIMs were defined based on Beers criteria 2019. Study outcomes included functional independence measure (FIM)-motor, FIM-cognitive, energy intake, dysphagia, length of hospital stay, and the rate of home discharge. To consider the effect of pharmacotherapy during rehabilitation, multivariate analyses were used to determine whether the presence of polypharmacy or PIMs at discharge was associated with outcomes. Results After enrollment, 361 patients (mean age 78.3 ± 7.7 years; 49.3% male) were analyzed. Polypharmacy was observed in 43.8% and 62.9% of patients, and any PIMs were observed in 64.8% and 65.4% of patients at admission and discharge, respectively. The most frequently prescribed PIMs included antipsychotics, benzodiazepines, and proton pump inhibitors. Polypharmacy was negatively associated with FIM-motor score (β = - 0.062, P = 0.049), FIM-cognitive score (β = - 0.076, P = 0.014), energy intake (β = - 0.143, P = 0.005), and home discharge (OR: 0.458; 95% CI: 0.248, 0.847; P = 0.013). PIMs were negatively associated with home discharge (OR: 0.375; 95% CI: 0.195, 0.718; P = 0.003). Conclusion Polypharmacy and PIMs are commonly found among older patients undergoing stroke rehabilitation. Moreover, polypharmacy was negatively associated with activities of daily living (ADL) but not with PIMs and ADLs, and both were associated with home discharge.

A multifactorial intervention to lower potentially inappropriate medication use in older adults in Argentina

BACKGROUND

Adverse drug reactions are a common cause of potentially avoidable harm, particularly in older adults.

AIMS

To evaluate the feasibility and efficacy of a pilot multifactorial intervention to reduce potentially inappropriate medication (PIM) use in older adults.

METHODS

We conducted a phase 2, feasibility, open-label study in the ambulatory setting of an integrated healthcare network in Buenos Aires, Argentina. We recruited primary care physicians (PCPs) and measured PIM use in a sample of their patients (65 years or older). Educational workshops for PCPs were organized with the involvement of clinician champions. Practical deprescribing algorithms were designed based on Beers criteria. Automatic email alerts based on specific PIMs recorded in each patient's electronic health record were used as a reminder tool. PCPs were responsible for deprescribing decisions. We randomly sampled 879 patients taking PIMs from eight of the most commonly used drug classes at our institution and compared basal (6 months prior to the intervention) and final (12 months after) prevalence of PIM use using a test of proportions.

RESULTS

There was a significant reduction (p < 0.05) in all drug classes evaluated. Non-Steroidal Anti-Inflammatory Drugs (basal prevalence 5.92%; final 1.59%); benzodiazepines (10.13%; 6.94%); histamine antagonists (7.74%; 3.07%); opioids (2.16%; 1.25%); tricyclic antidepressants (8.08%; 4.10%); muscle relaxants (7.74%; 3.41%), anti-hypertensives (3.53%; 1.82%) and oxybutynin (2.96%; 1.82%). The absolute reduction in the overall prevalence was 8.5 percentage points (relative reduction of 51.4%).

CONCLUSION

This multifactorial intervention is feasible and effective in reducing the use of potentially inappropriate medication in all drug classes evaluated.

Inappropriate drug use rates of geriatric patients attending to a university hospital cardiology policlinic

Background

The interest in risks related to inappropriate drug use (IDU) and polypharmacy among the elderly has increased in recent years.

Aims

We aimed to determine the frequency of IDU and multiple drug use in elderly patients in the cardiology outpatient clinic.

Patients and Methods

: In this prospective, cross-sectional study, a total of 513 patients aged 65 years and above who were admitted to the Cardiology Policlinic between December 2017 and January 2018 were included. To determine the prevalence of IDU, we investigated the suitability of the drugs used by the patients (according to the criteria of Beers 2015 and Screening Tool of Older People's Prescriptions [STOPP] version 2), the number of violated criteria in both the guidelines and which criterion was violated by the inappropriate drugs.

Results

: The 513 patients (mean age: 73.18 ± 5.99) in this study included females (n = 235; 45.8%) and males (n = 278; 54.2%). A total of 2,910 drugs were used by the 513 patients (mean per patient: 5.67 ± 2.51); 52.8% of the patients were using more than five drugs. The Beers criteria revealed that 304 IDUs were detected among the drugs and showed that 38.6% (n = 198) of the patients had IDU. According to the STOPP criteria, 366 IDUs were identified among the drugs used, and 45.6% (n = 234) of the patients had IDU.

Conclusion

IDU frequencies of the elderly patients are similar to the world literature in our study. As the number of chronic illnesses the patients had increases, the frequency of IDU increases according to Beers and STOPP criteria in our study.

The prevalence and risk factors of potentially inappropriate medication use in older Chinese inpatients with multimorbidity and polypharmacy: a cross-sectional study

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.

Potentially inappropriate medication use among older adult patients on follow-up at the chronic care clinic of a specialized teaching hospital in Ethiopia. A cross-sectional study

Background

Older adult patients are prone to potentially inappropriate medication use (PIMU); its use has been associated with multiple adverse consequences. As a result, it is crucial to determine the magnitude and factors associated with PIMU. The present study was mainly aimed to determine and assess the magnitude and predictors of potentially inappropriate medication use in older adult patients on follow-up at the chronic care clinic of Jimma medical center.

Methods

A retrospective cross-sectional study was conducted involving 219 patients aged 65 years and above on treatment follow-up. Data was collected using a checklist. The 2019 updated American Geriatric Society (AGS) Beers Criteria® and Screening Tool of Older People’s Potentially Inappropriate Prescriptions criteria and Screening Tool to Alert Doctors to Right Treatment (STOPP/START) criteria (version 2) were employed to assess PIMU. SPSS IBM (v22) was used for data entry and analysis. Categorical variables were described using frequency and percentage, whereas continuous variables were described using mean with standard deviation (SD) or median with interquartile range (IQR). Logistic regression was conducted to identify predictors of PIMU.

Results

The average number of medications prescribed per patient was 4.0 (IQR = 2.0). At least one PIMU was identified in 182 (83.1%) and 99 (45.2%) patients, based on Beers and STOPP criteria, respectively. Additionally, potential prescription omission (PPO) was observed in 24 (10.9%) patients. The risk of Beers PIMU was increased with age [AOR = 1.21, p <  0.001], hypertension [AOR = 4.17, p <  0.001], and polypharmacy [AOR = 14.10, p <  0.001], while a decrease in the risk was noted in patients with a diagnosis of ischemic stroke [AOR = 0.133, p = 0.01] and asthma [AOR = 0.03, p <  0.001]. Using STOPP criteria, hypertension [AOR = 2.10, p = 0.04], diabetes mellitus [AOR = 2.26, p = 0.04], ischemic heart disease [AOR = 2.84, p = 0.04], peripheral neuropathy [AOR = 10.61, p <  0.001], and polypharmacy [AOR = 6.10, p <  0.001] significantly increased the risk of PIMU.

Conclusions

Regardless of the screening tool used to assess, the present study revealed PIMU in the large proportion of the participants. Multiple medication use and certain disease condition had increased the probability of PIMU. Hence, it is imperative to use screening tools for reviewing medications prescribed in older adult patients to ensure safety of medication therapy.

Geriatrics on beers criteria medications at risk of adverse drug events using real-world data

OBJECTIVES

The established Beers Criteria consider side effects and safety concerns when prescribing drugs to the elderly. As the criteria suggest that attention should be paid toward prescriptions rather than prescription prohibition lists, these Beers Criteria medications (BCMs) are used appropriately under unavoidable circumstances.

METHODS

Patients aged ≥ 65 years and with an experience of being prescribed inappropriate medications at Konyang University Hospital, South Korea, were selected. We analyzed data from the Korea Adverse Event Reporting System (KAERS) and the Food and Drug Administration Adverse Event Reporting System (FAERS) of the United States to identify medication-induced adverse drug events (ADEs). The actual incidence was predicted by multiplying the incidence and number of BCMs prescribed to the patients. The proportional reporting ratio (PRR) and reporting odds ratio (ROR) were calculated using KAERS and FAERS data.

RESULTS

We predicted that the incidence of ADEs would be higher for metoclopramide, chlorpheniramine, and amitriptyline in patients using medications for more than 1 day and metoclopramide, chlorpheniramine, and ketoprofen in patients using medications only for 1 day. Among the ADEs reported to KAERS and FAERS, significant ROR and PRR values were noted for clonazepam (drowsiness), nortriptyline (sleepiness), and zolpidem (amnesia, somnambulism, agitation, dependence, nightmare, and dysgeusia).

CONCLUSION

This study highlighted the actual status of BCM prescriptions in clinical institutions and predicted the incidence of ADEs. We concluded that greater care must be taken while prescribing BCMs to the elderly and indicators, such as PRR and ROR should be monitored regularly.

Potentially Inappropriate Medication Use in the Elderly

It is estimated that approximately half of adults, older than 65 years of age, have been prescribed potentially inappropriate medications (PIMs). This study's objective was to determine the prevalence of PIM use among older patients. Two retrospective chart reviews were performed on 200 and 164 older patients who underwent comprehensive geriatric assessments (CGAs) at outpatient geriatrics clinics at the Glenrose Rehabilitation Hospital (Glenrose) in 2012-13 and at the Misericordia Community Hospital (Misericordia) in 2016-17, respectively. Outcome measures included demographics; prevalence of PIM use; common PIMs used; whether PIM use was addressed, and if so, how; and total number of oral medications. At the Glenrose, the prevalence of PIM use was 45 per cent (90/200). Of the 90 patients who had used PIMs, 46.7 per cent (42/90) had at least one of their medications stopped or modified. At the Misericordia, the prevalence of PIM use was 57.3 per cent (94/164). Of the 94 patients who used PIMs, 47.9 per cent (45/94) had at least one of their medications stopped or modified. These results suggest that an increased awareness of PIM among physicians is needed to further decrease PIM use.

Prescription Habits Related to Chronic Pathologies of Elderly People in Primary Care in the Western Part of Romania: Current Practices, International Recommendations, and Future Perspectives Regarding the Overuse and Misuse of Medicines

The European Commission’s 2019 report regarding the state of health profiles highlighted the fact that Romania is among the countries with the lowest life expectancy in the European Union. Therefore, the objectives of the present study were to assess the current prescription habits of general physicians in Romania related to medicines taken by the elderly population for chronic conditions in both urban and rural setting and to discuss/compare these practices with the current international recommendations for the elderly (American—Beers 2019 criteria and European—STOPP/START v.2, 2015 criteria). A total of 2790 electronic prescriptions for chronic pathologies collected from 18 community pharmacies in the western part of Romania (urban and rural zones) were included. All medicines had been prescribed by general physicians. We identified the following situations of medicine overuse: 15% of the analyzed prescriptions involved the use of nonsteroidal anti-inflammatory drugs (NSAIDs) for >2 weeks, 12% involved the use of a proton-pump inhibitor (PPI) for >8 weeks, theophylline was the bronchodilator used as a monotherapy in 3.17% of chronic obstructive pulmonary disease cases, and zopiclone was the hypnotic drug of choice for 2.31% of cases. Regarding the misuse of medicines, 2.33% of analyzed prescriptions contained an angiotensin-converting enzyme (ACE) inhibitor and an angiotensin II receptor blocker (ARB) for patients with renal failure in addition to vitamin K antagonists (AVKs) and NSAIDs in 0.43% of cases. Prescriptions for COX2 NSAIDs for periods longer than 2 weeks for patients with cardiovascular disorders accounted for 1.33% of prescriptions, and trihexyphenidyl was used as a monotherapy for patients with Parkinson’s disease in 0.18% of cases. From the included medical prescriptions, 32.40% (the major percent of 2383 prescriptions) had two potentially inappropriate medications (PIMs). Rural zones were found to be risk factor for PIMs. Decreasing the chronic prescription of NSAIDs and PPIs, discontinuing the use of hypnotic drugs, and avoiding potentially harmful drug–drug associations will have long term beneficial effects for Romanian elderly patients.

The risk of polypharmacy and potentially inappropriate drugs in residential care dementia patients: tips from the PharE study

AIMS

The aims of the present study, conducted in two regions of Italy, Calabria and Piedmont, were to assess the use of inappropriate drugs according to the Beers Criteria and to study the possible drug-drug interactions.

METHODS

Data were obtained retrospectively from 972 residential care patients between 2016 and 2018. Mean age was 82.4 ± 8.4 years, with a prevalence of women (64.8%). Activities of daily living, instrumental activities of daily living, Mini-Mental State Examination, Cumulative Illness Rating Scale, Neuropsychiatric Inventory Scale and number and kind of drugs were recorded. A classification of potential inappropriate drugs was made according to the Beers criteria. Data were collected through an Excel file able to gather the main information. In the case of suspected adverse event, Naranjo Scale was applied. The study of possible drug-drug interactions was made by Micromedex 2.0.

RESULTS

Functional and cognitive impairments, comorbidities and number of drugs were assessed. The bivariate relationship between number of drugs and glomerular filtration rate assessed by CKD-EPI showed that the higher was the number of drugs used, the worst was kidney function assessment (p = 0.0001). The most frequent inappropriate drugs were anticholinergic drugs, tricyclics antidepressants, long-half-life benzodiazepines, antipsychotics and proton pump inhibitors.

CONCLUSIONS

These data are very interesting and show the need for an accurate choice of drugs in elderly people and for starting a wise deprescribing procedure.

Rationally decreasing the number of drugs seems to be a useful therapeutic approach in older adults: 6-month follow-up study

AIMS

Older adults are at risk for polypharmacy, which has multidimensional safety, clinical and economic implications. Therefore, the optimization of drug therapy is one of the critical components of geriatrics clinical practice. This study is aimed to investigate the effect of drug rationalization on comprehensive geriatric assessment(CGA) parameters.

MATERIALS AND METHODS

The study was a retrospective and longitudinal study examining the effect of change in drug number on functionality and physical performance. A total of 515 patients were included in the study. Detailed medication history, laboratory findings, CGA parameters were recorded in the first admission. Polypharmacy was accepted as concurrent usage of five or more drugs. Medications of each patient were reviewed with the guidance of CGA and Beers Criteria.

RESULTS

The mean age of patients was 74.13 ± 7.29 years, and 68.7% were female. The baseline mean number of drugs was 5.11 ± 3.34. The polypharmacy group(269 patients) had a higher rate of geriatric syndromes and lower CGA scores in the first admission. After optimization of medications, the mean drug number decreased to 4.76 ± 2.72. Depression, mobility and nutritional scores improved at the end of six months in the patients whose total number of drugs decreased, while global cognition, activities of daily living scores, and gait speed were preserved. Increasing the number of drugs was associated with lower mobility and functionality.

CONCLUSION

Drug rationalization guided with CGA improves the nutritional, physical, and psychosocial status of geriatric patients. Thus, medication reviews have key importance in the management of older patients.

Comparison of adaptive versions of the Hong Kong-specific criteria and 2015 Beers criteria for assessing potentially inappropriate medication use in Hong Kong older patients

BACKGROUND

The Hong Kong-specific criteria have been established in 2019 to assess potentially inappropriate medication (PIM) use in older adults and improve the local prescribing quality. The aim of this study was to compare the adaptive versions of the Hong Kong-specific criteria and 2015 Beers criteria for assessing the prevalence and correlates of PIM use in Hong Kong older patients.

METHODS

A cross-sectional study was performed from January 1, 2014 to December 31, 2014 using the Hospital Authority (HA) database. A total of 489,301 older patients aged 65 years and older visiting general outpatient clinics (GOPCs) during the study period were included in the study. Two categories of PIM use included in the Hong Kong-specific criteria and 2015 Beers criteria, i.e. PIMs independent of diagnoses and PIMs considering specific medical conditions, were adapted to assess the prevalence of PIM use among the study sample. Characteristics of PIM users and the most frequently prescribed PIMs were investigated for each set of the criteria. Factors associated with PIM use were identified using the stepwise multivariable logistic regression analysis.

RESULTS

The adaptive Hong Kong-specific criteria could detect a higher prevalence of patients exposed to at least one PIM than that assessed by the adaptive Beers criteria (49.5% vs 47.5%). Meanwhile, the adaptive Hong Kong-specific criteria could identify a higher rate of patients exposed to PIMs independent of diagnoses (48.1% vs 46.8%) and PIMs considering specific medical conditions (7.3% vs 4.9%) compared with that of the adaptive Beers criteria. The most frequently prescribed PIMs detected by the adaptive Beers criteria were all included in the adaptive Hong Kong-specific criteria. The strongest factor associated with PIM use was number of different medications prescribed. Patients with female gender, aged 65 ~ 74 years, a larger number of GOPC visits, and more than six diagnoses were associated with greater risk of PIM use, whereas advancing age was associated with lower risk of PIM use.

CONCLUSIONS

The adaptive Hong Kong-specific criteria could detect a higher prevalence of PIM use than the adaptive Beers criteria in older adults visiting GOPCs in Hong Kong. It is necessary to update the prevalence and correlates of PIM use regularly in older adults to monitor the burden of PIM use and identify vulnerable patients who need further interventions.

Potentially Inappropriate Medication and Associated Factors Among Older Patients with Chronic Coronary Syndrome at Hospital Discharge in Beijing, China

Purpose

Medication therapy is crucial in the management of chronic coronary syndrome (CCS). The use of potentially inappropriate medications (PIMs) contributes to poor outcomes in older patients, making it a major public health concern. However, few studies are available on PIMs use in older Chinese CCS patients. To investigate the frequency of prescribed PIMs at discharge and explore risk factors in older adults with CCS.

Patients and Methods

The cross-sectional study was conducted in a tertiary hospital in China over three months, from 1st October to 31st December, 2019. CCS patients aged over 60 years who were discharged alive were recruited. Information on demographics and medications at discharge was collected. Clinical data including diagnoses, frailty status, New York Heart Association (NYHA) class and age-adjusted Charlson Comorbidity Index (ACCI) were evaluated in each patient. PIMs were identified using the 2019 Beers criteria. Binary logistic regression was performed to recognize variables related to PIMs.

Results

A total of 447 eligible patients with 2947 medications were included. The prevalence of PIMs use was 38%. Medications to be avoided, to be used with caution, and with drug–drug interactions were 38.4%, 48.9% and 12.7% of the PIMs, respectively. Medications with drug–disease/syndrome interactions and those adjusted for kidney function were not identified. The common PIMs were diuretics (37.1%), benzodiazepines and benzodiazepine receptor agonist hypnotics (15.2%), glimepiride (13.1%), and co-prescription of potassium-sparing diuretics and renin-angiotensin system (RAS) inhibitors (9.7%). Individuals with frailty syndrome, polypharmacy, multiple comorbidities, atrial fibrillation, psychiatric disorders and greater NYHA class severity were more likely to receive PIMs.

Conclusion

Prescription of PIMs was a common burden in older adults. A CCS multidisciplinary team is needed to control PIMs, especially in vulnerable older patients.

Evaluation of psychotropic medications use among elderly with psychiatric disorders in Saudi Arabia

AIMS

Potentially inappropriate psychotropic medications (PIPMs) prescribed to older adults with psychiatric disorders can inadvertently affect their health. The use of standards and guidelines can ensure prudent prescribing and minimize the risk of morbidities. This study assessed the pattern and prevalence of prescription of PIPMs to older individuals in outpatient psychiatric settings in Saudi Arabia, using the updated 2015 Beers criteria, as well as the probability of polypharmacy.

METHODS

The study was conducted in the outpatient psychiatric clinics of the only psychiatric hospital in Jazan region of Saudi Arabia. A retrospective cross-sectional review of electronic medical records was undertaken during 2018 to assess PIPM use and psychotropic polypharmacy. Descriptive statistics were generated and associations between PIPM use and baseline characteristics were assessed using multivariable logistic regression.

RESULTS

Overall, 68% of 1300 older adults received PIPMs, and 77.7% were on psychotropic polypharmacy. Amitriptyline, chlorpromazine, and trifluoperazine were extensively prescribed. Paroxetine (1.2%) and benzodiazepines were prescribed to a smaller proportion of the patients. Elderly with schizophrenia (AOR = 0.046, p < 0.001) and anxiety (AOR = 0.530, p = 0.036) were significantly less likely to have PIPMs than those with dementia. Likewise, elderly with depression and anxiety were less likely to have psychotropic polypharmacy as compared to those with dementia.

CONCLUSION

A substantial number of the elderly received PIPMs possibly based on implicit criteria. It is therefore important to provide mental health care providers in the region with educational programs to increase their awareness of PIPMs.

Geriatric emergency department revisits after discharge with Potentially Inappropriate Medications: A retrospective cohort study

OBJECTIVE

To determine whether Potentially Inappropriate Medications (PIMs) prescribed in an academic emergency department (ED) are associated with increased ED revisits in older adults.

METHODS

A retrospective chart review of Medicare beneficiaries 65 years and older, discharged from an academic ED (January 2012 - November 2015) with any PIMs versus no PIMs. PIMs were defined using Category 1 of the 2015 Updated Beers criteria. Primary outcomes, obtained from a Medicare database linked to hospital ED subjects, were ED revisits 3 and 30 days from index ED discharge. Adjusted multiple logistic regression was used with entropy balance weighted covariates: Age in years, Gender, Race, Number of discharge medications, Charlson Comorbidity Index (CCI) score, Emergency Severity Index scores (ESI), Chief Complaint, Medicaid status, and prior 90 Day ED visits.

RESULTS

Over the study period, there were a total of 7,591 Medicare beneficiaries 65+ discharged from the ED with a prescription; 1,383 (18%) received one or more PIMs. ED revisits in 30 days were fewer for the PIMs cohort (12% PIMs vs 16% no PIMs, OR 0.79, 95% CI 0.65 - 0.95, P value <0.005). Hospital admissions in 30 days were fewer for the PIMs cohort (4 PIMs vs 7% no PIMs, OR 0.75, 95% CI 0.56 - 1.00, P value <0.005). In addition to PIMs, covariate risk factors associated with ED revisits in 30 days included comorbidity severity, history of prior ED revisits, chief complaint, and Medicaid status. Risk factors associated with hospitalization in 30 days included those plus age and emergency severity index, but not race nor ethnicity.

CONCLUSIONS

Patients discharged from the ED receiving potentially inappropriate medications as defined by Category 1 of the 2015 updated Beers criteria had lower odds of revisiting the ED within 30 days of index visit. Sociodemographic factors such as gender and race did not predict ED revisits or hospital admissions. Clinical characteristics predicted ED revisits and hospital admissions, the strongest risk being increasing Charlson Comorbidity Index score followed by triage acuity and chief complaint. Future studies are needed to delineate the implications of our findings.

Potentially inappropriate prescribing and its associations with health-related and system-related outcomes in hospitalised older adults: A systematic review and meta-analysis

AIMS

To synthesise associations of potentially inappropriate prescribing (PIP) with health-related and system-related outcomes in inpatient hospital settings.

METHODS

Six electronic databases were searched: Medline Complete, EMBASE, CINAHL, PyscInfo, IPA and Cochrane library. Studies published between 1 January 1991 and 31 January 2021 investigating associations between PIP and health-related and system-related outcomes of older adults in hospital settings, were included. A random effects model was employed using the generic inverse variance method to pool risk estimates.

RESULTS

Overall, 63 studies were included. Pooled risk estimates did not show a significant association with all-cause mortality (adjusted odds ratio [AOR] 1.10, 95% confidence interval [CI] 0.90-1.36; adjusted hazard ratio 1.02, 83% CI 0.90-1.16), and hospital readmission (AOR 1.11, 95% CI 0.76-1.63; adjusted hazard ratio 1.02, 95% CI 0.89-1.18). PIP was associated with 91%, 60% and 26% increased odds of adverse drug event-related hospital admissions (AOR 1.91, 95% CI 1.21-3.01), functional decline (AOR 1.60, 95% CI 1.28-2.01), and adverse drug reactions and adverse drug events (AOR 1.26, 95% CI 1.11-1.43), respectively. PIP was associated with falls (2/2 studies). The impact of PIP on emergency department visits, length of stay, and health-related quality of life was inconclusive. Economic cost of PIP reported in 3 studies, comprised various cost estimation methods.

CONCLUSIONS

PIP was significantly associated with a range of health-related and system-related outcomes. It is important to optimise older adults' prescriptions to facilitate improved outcomes of care.

Comparison of the extent and prevalence of prescription of potentially inappropriate medications prescribed to geriatric age group residing in old-age homes versus those receiving care from tertiary care hospital using Beers criteria

Context:

Certain medications have higher chances of causing adverse effects in geriatric age group. Evidence is against prescribing these medications to the elderly. A list of such medications is called Beers criteria, which was revised by the American Geriatrics Society in 2015.

Aims:

Using the Beer's list as reference, the researchers intend to find the extent and prevalence of potentially inappropriate medication (PIM) in geriatric population residing in different settings.

Settings and Design:

The researchers analyzed prescription pattern of 200 individuals with age ≥65 years, 100 individuals from old-age homes (OAHs) and 100 individuals from a tertiary care hospital. After collecting data, the researchers tallied each prescription with list of drugs in Beers criteria to find all the possible PIMs in both the groups.

Results:

It was found that the average age of residents of OAHs was significantly higher (P < 0.002) than the corresponding group from a tertiary care hospital. The residents of OAHs were also a receiving significantly higher (P < 0.0001) number of PIM than their counterparts from the tertiary care hospital. The average number of PIMs prescribed to females in OAHs was also significantly higher than those in the other group. About 55% of residents of OAHs received at least one PIM, compared to just 26% in the other group. At least 27% of individuals of OAHs received two or more PIMs, compared to just 2% in a tertiary care hospital. Lorazepam was the most commonly prescribed PIM in OAHs, whereas ranitidine was the most common PIM in a tertiary care hospital. Ibuprofen was the second most common PIM, with 15% of OAHs residents receiving this drug, while none of the patients from a tertiary care hospital received ibuprofen.

Conclusion:

All the results point toward a poor prescription pattern in the residents of OAHs compared to those receiving care from a tertiary care hospital.

Potentially inappropriate medications prescribing to elderly patients with advanced chronic kidney by using 2019 American Geriatrics Society Beers Criteria

BACKGROUND AND AIMS

A potentially inappropriate medication (PIM) is defined as a drug-carrying risks outweighing the expected clinical benefits. Elderly patients with chronic kidney disease (CKD) are particularly at higher risk of drug-related toxicities. In Lebanon, no studies have been conducted regarding the prescribing of PIMs in hospitalized CKD patients. This study aimed to check the prevalence of PIMs using the American Geriatrics Society (AGS) Beers criteria in elderly patients with advanced CKD stages including dialysis and to identify possible risk factors that may be associated with prescribing PIMs in this population.

METHODS

A retrospective cross-sectional study was conducted on patients with advanced CKD above the age of 65 years and admitted between January 2019 and June 2019 to two University Hospitals in Beirut, Lebanon. We used multiple logistic regression analysis to determine which factors were associated with prescription of PIMs according to AGS Beers criteria-2019.

RESULTS

The study sample included 199 patients with renal dysfunction, 75.9% were aged 70 years or more, 53.8% were females, and 61.8% were prescribed five drugs or more. Eighty-two patients were receiving hemodialysis (41.2%). PIMs prevalence was 34.1% (68/199 patients) according to Beers criteria in elderly patients with advanced CKD stages.The most frequently prescribed PIMs were ranitidine (39.1%), enoxaparin (25%), tramadol (9.8%), and ciprofloxacin (5.4%). Polypharmacy (OR 2.1, CI 95% 1.58-2.79), a higher number of comorbidities (OR 3.01, CI 95% 1.43-6.30), and coronary artery diseases (OR 3.14 CI 95% 1.44-6.85) were the factors associated with an increased risk of at least one PIM prescription.

CONCLUSION

Our study found that one out of three patients with advanced CKD had at least one PIM according to the latest Beers criteria. A large proportion of inappropriate prescribing is preventable by increasing awareness of prescribing physicians to the explicit lists of PIMs.

Adherence to Beers Criteria in Geriatrics: A Retrospective Study in a Saudi Teaching Hospital

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.

Potentially inappropriate medication in acute hospitalized elderly patients with polypharmacy: an observational study comparing PRISCUS, STOPP, and Beers criteria

PURPOSE

To compare the prevalence of potentially inappropriate medication (PIM) in the elderly according to the PRISCUS list, STOPP criteria, and Beers criteria. Secondary, to describe the differences using the three criteria focused on the inappropriate prescription of psychotropic drugs in the elderly.

METHODS

A retrospective study was performed at Severo Ochoa University Hospital. The study included 365 patients, aged 80 years and older, living in Madrid, Spain.

RESULTS

93.42% of patients received at least one PIM during hospitalization. Using the PRISCUS list, this changed from 32.6 to 2.7% at discharge. Applying STOPP criteria lowered the percentage from 65.20 to 10.95%, and with Beers criteria from 80.27 to 10.13. Lower Barthel index at admission was associated with an increased relative risk for receiving at least one PIM (OR 1.79, 95% CI 1.15-2.80, p = 0.024) using PRISCUS list as a tool in conjunction with STOPP criteria (OR 1.44, 95% CI 0.89-2.33, p = 0.037). Polypharmacy at admission predicted the presence of PIMs with STOPP criteria (OR 1.74, 95% CI 1.07-2.84, p = 0.001). Regarding psychotropic medicines, 208 patients (56.98%) received at least one psychotropic medicine during hospitalization. A total of 26.30% of patients were treated with psychotropic medicines, detected by the PRISCUS list, and 53.97% and 29.85% with STOPP and Beers, respectively.

CONCLUSIONS

Explicit criteria are a useful tool for identifying during hospitalization of the elderly patients. As indicated by the results, new research is needed to carry out an adaptation in our country that includes an evaluation of the strengths of the three tools to decrease PIMs and improve prescription in the elderly.

Impact of a nationwide prospective drug utilization review program to improve prescribing safety of potentially inappropriate medications in older adults: An interrupted time series with segmented regression analysis

PURPOSE

A nationwide prospective drug utilization review (DUR) for potentially inappropriate medications (PIMs) in older adults was implemented in October 2015 in South Korea. We aimed to evaluate the effects of the DUR on reducing PIMs, in comparison with the PIMs defined using the Beers criteria that were not included in the DUR.

METHODS

We divided the study period into a pre- and post-DUR period. The monthly percentage of patients or prescriptions with at least one PIM in the DUR or defined by the Beers criteria was calculated using national health insurance data. We evaluated the effect of the DUR on the prevalence of PIM use in older adults using an interrupted time series with segmented regression analysis.

RESULTS

The prevalence of older adults prescribed PIMs in the DUR decreased by 0.49% (95% confidence interval (CI) [-0.60, -0.37]) based on patient-based measures and, by 0.41% (95% CI [-0.58, -0.23]) based on prescription-based measure, immediately after DUR implementation. However, there were no statistically significant changes in trend. Further, the prevalence of PIMs based on the Beers criteria had no statistically significant changes in terms of either level or trend. After 12 months of DUR, there was a reduction of 11.5% (95% CI [2.6 20.4]) relative to the PIMs in Beers.

CONCLUSIONS

The implementation of a nationwide prospective DUR lowered the prescription of PIMs for older adults. On the other hand, PIMs that were not included were unchanged. Thus, it is worth considering expanding the DUR list to improve prescribing safety.

Potentially Inappropriate Medication Combination with Opioids among Older Dental Patients: A Retrospective Review of Insurance Claims Data

BACKGROUND

Opioid prescribing by dentists for older patients receiving medications with potential contraindications and the subsequent impact on acute care outcomes is not well described.

OBJECTIVES

Our objective of this paper was to evaluate the use of potentially inappropriate medication combinations (PIMCs) involving opioids prescribed by dentists according to the Beers Criteria and risks of 30-day emergency department (ED) visits and all-cause hospitalization among commercially insured dental patients ages 65 years and older.

METHODS

We conducted a retrospective cohort study of 40,800 older dental patient visits in which opioids were prescribed between 2011 and 2015 using the IBM MarketScan databases. Data collection from dental, medical, and pharmacy claims included information on the concurrent use of PIMCs and outcomes of all-cause acute care utilization over the 30-day period after dental encounters.

RESULTS

For the overall cohort, the median age was 69 years, and 45% were women. The prevalence of PIMCs per Beers Criteria was 10.4%. A total of 947 all-cause acute care events were observed in the 30 days post-dental visit. Patients with PIMCs involving opioids prescribed by dentists according to the Beers Criteria had higher rates of acute care use (3.3% vs 2.2%, p<0.001), which were associated with an increased risk of all-cause acute care utilization (adjusted risk ratio [RR] 1.23, 95% confidence interval [CI] 1.02-1.48). A dose-response relationship was seen with increasing oral morphine equivalents prescribed and increased acute care utilization (p<0.001).

CONCLUSION

A significant proportion of older patients receiving opioids at dental visits use psychotropic medications that in combination should be avoided according to the American Geriatric Society Beers Criteria.

Potentially inappropriate medications in older individuals with diabetes: A population-based study in Quebec, Canada

AIM

To study the population-based prevalence of potentially inappropriate medication (PIM) among older individuals with diabetes, and to identify factors associated with their use.

METHODS

We used the Quebec Integrated Chronic Disease Surveillance System (QICDSS) database to conduct a population-based cohort study of individuals with diabetes ≥66 years between April 1st, 2014 and March 31st, 2015. PIMs were defined according to the 2015 Beers Criteria. Factors associated with PIM use were identified using robust Poisson regression models. Risk ratios (RR) and 99% confidence intervals (99%CI) were calculated.

RESULTS

More than half (56%) of the 286,962 older individuals with diabetes used at least one PIM over a year. Benzodiazepines (41%), proton pump inhibitors (27%) and endocrine medication (mainly glibenclamide) (25%) were the most common PIMs used. Factors associated with PIM use included female sex (RR: 1.17; 99%CI: 1.16-1.18), and comorbidities such as schizophrenia (1.48; 1.45-1.51), anxiety disorders (1.34; 1.33-1.35) and Alzheimer's disease (1.14; 1.13-1.25). Risks of using PIMs increased both with increasing comorbidities and number of medications.

CONCLUSION

PIM use is highly prevalent among older individuals with diabetes. Interventions to promote optimal medication use should particularly target individuals with comorbidities and polypharmacy who are most vulnerable to adverse drug events.

Patterns of Psychoactive Medication Use in Community-Dwelling Older Adults in the US in 2016: A Descriptive Cross-Sectional Study

Objectives: We aim to quantify any use and long-term use patterns of psychoactive medications and explore differences in use by sociodemographic factors in older adults (60-85 years) using the 2016 Medical Expenditure Panel Survey. Methods: Prevalence estimates of any use and long-term use were calculated. Chi-square and crude odds ratios were calculated to estimate differences in any use and long-term use of psychoactive medication by sociodemographic characteristics of respondents. Results: Thirty percent of older adults in the US reported any use of psychoactive medications. Long-term use was significantly higher in women (28.3% [95% confidence interval: 26.5, 30.2]), white (27.8 [26.1, 29.7]), presently unmarried (27.5 [25.4, 29.7]), and low-income (30.3 [27.7, 32.9]) subgroups than in men (20.5 [18.4, 22.5]), Black (14.7 [12.3, 17.1]), presently married (22.8 [20.7, 24.9]), and high-income (21.1 [19.1, 23.1]) subgroups, respectively. Discussion: Despite continued risks associated with use, long-term use of psychoactive medications is prevalent in the older adult population in the US. Given the increased complexity of pharmacotherapy regimens in this population, enhanced efforts at improving use of psychoactive medications should be intensified.

Use of Potentially Inappropriate Medications in Older Allogeneic Hematopoietic Cell Transplantation Recipients

The use of potentially inappropriate medications (PIMs) using Beers criteria and its impact on older allogeneic hematopoietic cell transplantation (HCT) recipients is not known. Here the use of any PIMs and their therapeutic classes in reduced-intensity conditioning allogeneic HCT recipients were compared between older (≥65 years; n = 114) and younger (40 to 64 years; n = 240) patients during their initial HCT admission, defined as the number of days that a patient received 1 or more PIMs between day -14 and day +28. Poisson regression was used to determine rate ratios (RRs) in the 2 groups. In the ≥65 years group, we evaluated the impact of PIMs on Common Terminology Criteria for Adverse Events (CTCAE) grade 3-4 toxicities within 100 days and on overall mortality within 1 year post-HCT. The rate of any PIM use was similar in the older and younger groups (RR, .98; 95% confidence interval [CI], .90 to 1.06; P = .65). In terms of PIM classes, the older group had a 48% higher rate of gastrointestinal (GI) medication use (RR, 1.48; 95% CI, 1.32 to 1.65; P < .01) and a 25% higher rate of genitourinary (GU) medication use (RR, 1.25; 95% CI, 1.02 to 1.53; P = .03). Compared with males, females had a 19% higher rate of central nervous system (CNS) medication use (RR, 1.19; 95% CI, 1.03 to 1.37; P = .02) and a 30% higher rate of benzodiazepine use (RR, 1.30; 95% CI. 1.09 to 1.54; P < .01). A high-risk HCT-CI was associated with a higher rate of use of any PIMs (RR, 1.13; 95% CI, 1.01 to 1.26; P = .02), CNS medications (RR, 1.26; 95% CI, 1.04 to 1.53; P = .02) and GU medications (RR, 1.46; 95% CI, 1.09 to 1.94; P = .01). Compared with matched sibling donor HCT recipients, umbilical cord blood transplantation recipients had higher rates of GI medication use (RR, 1.32; 95% CI, 1.14 to 1.53; P < .01) and anticholinergic medication use (RR, 1.30; 95% CI, 1.06 to 1.61; P = .01). In the ≥65 years group, increasing duration of narcotic use was associated with a 1.3-fold (95% CI, 1.0 to 1.7; P = .05) higher risk of overall mortality and a 1.6-fold (95% CI, 1.02 to 2.69) greater odds of CTCAE grade 3-4 toxicities (P = .04). Our data show that older recipients (≥65 years) were as likely as their younger counterparts to receive PIMs. Among older recipients, the use of PIMs, particularly narcotics, was associated with higher mortality and higher incidence of grade 3-4 toxicities. Identifying and reducing the use of PIMs in older HCT recipients may help decrease the burden of adverse events and associated health care costs.

Prevalence of potentially inappropriate medication and its correlates in elderly hospitalized patients: A cross-sectional study based on Beers criteria

BACKGROUND

The increase in the prescription of potentially inappropriate medication (PIM) in older adults with significant health consequences is a global concern. This study aimed to determine the prevalence of PIM prescription in older adults as identified by Beers criteria 2015 and 2019.

MATERIALS AND METHODS

A cross-sectional study was carried out in older adults aged >65 years at a tertiary care postgraduate teaching hospital. All patients aged ≥65 years irrespective of their gender, admitted in the medical ward of the hospital with single/multiple comorbidities, and prescribed at least one daily medication, were included in the study. Data of patient history, patient case sheet, medication charts, laboratory reports, as well as radiological examinations test reports were retrieved from their files and were captured in a prevalidated data collection form. SPSS used for data analysis; multivariate logistic regression was used to determine the predictors of PIM prescribing and odds ratios (ORs) and 95% confidence intervals for ORs were computed.

RESULTS

Study included 323 patients; 61.3% were male, 74% patients were 65-70 years of age, and 78% patients were illiterate. The overall prevalence of PIM uses according to the Beers criteria 2015 and 2019 was 60.1% and 61.9%, respectively. No association found between PIMs prescribes and diagnosis category. Male gender, age 76-80 years, and education 10-12th class were found to be significantly related to PIM prescription.

CONCLUSION

This study reflects a critical view of noncompliance of Beers criteria for geriatric healthcare even in tertiary care hospitals in India. Creatinine clearance rate should be kept in view when prescribing medicines for elderly inpatients.

Potentially Inappropriate Prescribing among Elderly Patients at a Primary Care Clinic in Oman

Drug prescribing to the elderly increases the risk of potential adverse drug reactions as well as potentially inappropriate medications. The goal of this study was to describe drug prescribing patterns in elderly patients and to measure the prevalence of potentially inappropriate medications using updated Beers' criteria and the STOPP criteria. This was a retrospective cross-sectional study for all patients aged ≥65 years who attended regularly a primary care clinic at Sultan Qaboos University Hospital in Oman. Data of 377 patients were analyzed using the software Statistical Package for Social Sciences version 23.0 (SPSS™, Chicago, IL, USA). Using Beers criteria, the prevalence of potentially inappropriate medications was 12.7% as 48 patients had at least one potentially inappropriate medication. Beers criteria revealed a statistical association between the occurrence of potentially inappropriate medications with polypharmacy (p < 0.001), with female gender (p = 0.002) and with asthma as a comorbidity (p = 0.020). STOPP criteria showed that the prevalence of potentially inappropriate medications was 17.2% as 65 patients had at least one potentially inappropriate medication. STOPP criteria revealed a statistical association between the occurrence of potentially inappropriate medications and osteoarthritis as a comorbidity (p = 0.032). The study revealed moderate prevalence of potentially inappropriate medications prescribing in elderly patients which was mainly associated with polypharmacy and female gender. Safe prescribing practices in the elderly requires increasing the awareness of healthcare providers and efficiently reporting drug-related problems.

Potentially inappropriate medication use and related hospital admissions in aged care residents: The impact of dementia

AIMS

To determine the prevalence of potentially inappropriate medication (PIM) use at hospital admission and discharge, and the contribution to hospital admission among residential aged care facility residents with and without dementia.

METHODS

We conducted a secondary analysis using data from a multihospital prospective cohort study involving consecutively admitted older adults, aged 75 years or older, who were taking 5 or more medications prior to hospital admission and discharged to a residential aged care facility in South Australia. PIM use was identified using the 2015 Screening Tool for Older Persons' Prescription and 2019 Beers criteria. An expert panel of clinicians with geriatric medicine expertise evaluated the contribution of PIM to hospital admission.

RESULTS

In total, 181 participants were included, the median age was 87.5 years and 54.7% were female. Ninety-one (50.3%) had a diagnosis of dementia. Participants with dementia had fewer PIMs, according to at least 1 of the 2 screening criteria, than those without dementia, at admission (dementia: 76 [83.5%] vs no dementia: 84 [93.3%], P = .04) and discharge (78 [85.7%] vs 83 [92.2%], P = .16). PIM use was causal or contributory to the admission in 28.1% of study participants (n = 45) who were taking at least 1 PIM at admission.

CONCLUSIONS

Over 80% of acutely admitted older adults took PIMs at hospital admission and discharge and for over a quarter of these people the admissions were attributable to PIM use. Hospitalisation presents an opportunity for comprehensive medication reviews, and targeted interventions that enhance such a process could reduce PIM use and related harm.

Assessment of direct oral anticoagulants administered as potentially inappropriate medications to elderly inpatients

Background There is evidence that direct oral anticoagulants administered as potentially inappropriate medications increase the risk of bleeding and thromboembolic complications, which represent serious threats to human health. Objective To identify direct oral anticoagulants administered as potentially inappropriate medications for hospitalized patients aged ≥ 65 years in our hospital, and to determine associated factors and the correlation between potentially inappropriate medications and adverse reactions. Setting Xi'an Central Hospital, China. Method A retrospective cross-sectional study of elderly hospitalized patients who received either dabigatran or rivaroxaban at Xi'an Central Hospital between June 1, 2018 and June 1, 2019. The evaluation criteria of direct oral anticoagulants were formulated based on drug labels, disease guidelines and the 2019 American Geriatrics Society Beers Criteria, and any non-compliance with the criteria was considered to be potentially inappropriate medications. The Pearson chi-square test and a binary logistic regression model were used. Main outcome measure Factors associated with potentially inappropriate medications and correlation between potentially inappropriate medications and adverse reactions. Results This study analysed 315 patients aged ≥ 65 years. The application of our evaluation criteria identified 155 (49.2%) instances of potentially inappropriate medications, comprising 5 different types of potentially inappropriate medications. Fifteen adverse drug reactions occurred in the study participants. The Pearson chi-square test revealed significant differences in number of medications (p = 0.021) and creatinine clearance rate (p = 0.002) between potentially inappropriate medications and non-potentially inappropriate medications groups. In the binary logistic regression model, potentially inappropriate medications use was associated with creatinine clearance (creatinine clearance < 30: OR = 3.590, 95% CI = 1.214-10.615, p = 0.021), and there was no significant correlation between potentially inappropriate medications and adverse drug reactions after eliminating the confounding factors (age, length of hospitalization, number of disease combined) with p values of less than 0.25 (adjusted OR = 0.372, 95% CI = 0.117-1.182, p = 0.094). Conclusion This study revealed that the incidence of potentially inappropriate medications was relatively high, number of medications and creatinine clearance differed significantly between potentially inappropriate medications and non-potentially inappropriate medications groups, and potentially inappropriate medications was associated with creatinine clearance (creatinine clearance < 30 mL/min), but there was no significant correlation between potentially inappropriate medications and adverse drug reactions after eliminating the confounding factors.

Potentially inappropriate medications for older adults in a primary healthcare unit in southern Brazil

Background Potentially inappropriate medications for older adults are those that offer more risks than benefits for this population. Such medications found in older adults' prescriptions across the world are associated with higher rates of comorbidities and hospitalizations, along with high expenditure on healthcare resources. Objectives To estimate the frequency of older adults using potentially inappropriate medications according to four different criteria, to identify factors associated with the use of such medicines and differences between the tools. Setting A primary healthcare unit linked to a university hospital in Porto Alegre, Brazil. Method This was a cross-sectional study conducted via data collection from the electronic medical records of 390 older adults. The information collected comprised sex, age, chronic diseases diagnosed and medications used. The dependent variable of the study was the use of at least one potentially inappropriate medication, according to the following criteria: Beers, Screening Tool of Older Persons' Prescriptions (STOPP), Brazilian consensus and Anticholinergic Risk Scale (ARS). Main outcome measurement Prevalence of inappropriate medication, differences between the tools and associated factors. Results: The use of at least one potentially inappropriate medication was found in 55.1% of the sample according to the Beers criterion, 51.3% according to the Brazilian consensus, 42.6% according to STOPP and 23.6% according to ARS. It was also seen that 14.9% of the studied population was exposed to a very strong anticholinergic risk. Depending on which tools were used, the agreement observed between the criteria was considered high, moderate, or low. Regarding the four criteria, the use of potentially inappropriate medication is associated with polypharmacy, the diagnosis of three or more chronic diseases and the presence of neuropsychiatric and musculoskeletal diseases. Conclusion Among the older adult population studied, the prevalence of potentially anappropriate medication is high, according to the four different classification criteria used. As a more specific tool, the agreement between Anticholinergic Risk Scale and other criteria was lower, but it can be an important complement to other lists.

Potentially inappropriate medications in older patients based on Beers criteria: a cross-sectional study of a family medicine practice in Saudi Arabia

BACKGROUND

The use of potentially inappropriate medications (PIMs) is an important issue in older patients who are at risk of adverse drug events.

AIM

To determine the prevalence of PIM use, according to Beers criteria, among an older population (aged ≥65 years) in a large family medicine setting, and to identify the associated risks.

DESIGN & SETTING

A prospective cross-sectional study of patients aged ≥65 years was conducted from June 2017 to June 2018 at the Family and Community Medicine (FCM) clinics of King Saud Medical City (KSMC) in Riyadh, Saudi Arabia.

METHOD

This cross-sectional study included patients aged ≥65 years who were seen at new appointments or followed-up at the FCM clinics of KSMC in Riyadh, Saudi Arabia. Data were collected by extensive face-to-face interviews and from the patients' medical records.

RESULTS

A total of 270 older patients aged 72.41 ±6.23 years (mean ±standard deviation [SD]) were included in the present study. The prevalence of PIMs was 60.7% (n = 164). Multivariate analyses identified three independent variables associated with PIMs: incremental age per 5 years (odds ratio [OR] 1.47, 95% confidence intervals [CI] = 1.15 to 1.88; P = 0.002), female sex (OR 1.95, 95% CI = 1.10 to 3.42; P = 0.021), and polypharmacy (OR 8.21, 95% CI = 4.58 to 14.7; P<0.001). The most common PIMs used were 39.4% related to proton pump inhibitors (PPI), 25.2% to diuretics (other than spironolactone), 10.6% to non-steroidal anti-inflammatory drugs (NSAIDs), and 8.7% to aspirin use.

CONCLUSION

This study showed high prevalence of PIMs. Increasing age, female sex, and polypharmacy were found to be significant risk factors for PIM use. The frequency of morbidities was not significantly different among patients with PIMs compared to those without PIMs, except for hypertension and osteoarthritis, which were more common in the PIMs group. The present study reinforces the importance of comprehensive medication management and reviews.

Prescribing for geriatrics in Tehran; is it appropriate and rational?

Background: The world’s population is growing older. Inappropriate and irrational use of drugs in the elderly is a considerable health concern due to consequences such as increased morbidity and adverse drug events. This study aimed to evaluate the rationality of prescribing and determining the extent of inappropriate prescribing in a sample of geriatric patients in Tehran.

Methods: This cross sectional study was performed on 1512 prescriptions of patients aged ≥ 65 years from 5 pharmacies affiliated to Tehran University of Medical Sciences in 2014. Prescription of potentially inappropriate medications (PIMs) was investigated using the Beers Criteria along with WHO prescribing indices. Date were analyzed using SPSS software, and significance level was set at less than 0.05.

Results: Mean (SD) age of patients was 73.9(6.7) years. A total of 472 (31.2%) patients received at least 1 PIM. Benzodiazepines were the most frequent drug class and general practitioners (GPs) were the most frequent prescriber of PIMs. The highest and the lowest percentage of prescriptions containing brand-names were prescribed by subspecialists (62.5%) and GPs (42.2%), respectively. Antibiotics and injectable medications were prescribed for 26.8% and 28.5% of patients by GPs. Mean (SD) number of drugs per prescription was 3.57 (1.92). Prescriptions containing systemic antibiotics and PIMs had significantly higher mean number of drugs compared to those without these items (both P < 0.001).

Conclusion: There is a need for interventions to improve the quality of prescribing for elderly patients, especially by GPs. Also, there are still some problems in rational use of drugs based on prescribing indices, especially, prescribing brand-names and injectable medications.
