An age-stratified cross-sectional study of antidiabetic and non-antidiabetic drugs prescribed to Japanese outpatients with diabetes. Glob Health Med 2023; 5:294-300. [PMID: 37908508 PMCID: PMC10615024 DOI: 10.35772/ghm.2023.01059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 08/18/2023] [Accepted: 08/28/2023] [Indexed: 11/02/2023]
Abstract
Polypharmacy, common in patients with diabetes, may cause adverse drug reactions. The number of antidiabetic and non-antidiabetic drugs prescribed to patients in different age groups remains unclear. The aim of this study was to examine the number and class of antidiabetics and non-antidiabetics prescribed to Japanese patients with diabetes, stratified by age for reducing polypharmacy. This cross-sectional study examined all prescriptions of patients prescribed antidiabetics at 257 pharmacies of Matsumotokiyoshi Holdings in Japan from May 2018 to March 2019. Total prescription numbers including antidiabetic drugs were 263,915 in this study. Mean numbers of antidiabetic drugs per prescription were 1.71, 2.17, and 1.52 in the patient age groups of 10-19, 50-59, and 90-99 years, respectively. Count of antidiabetics was not related to age. However, the mean total number of drugs prescribed increased with age, which was 2.22 and 7.99 in the age groups of 10-19 and 90-99 years, respectively. The linear regression coefficient (b) according to age was 0.07 (p < 0.001) for 10-99 years. The mean non-antidiabetic number of agents prescribed increased with age among 10-99 years (b = 0.07, p < 0.001). Among outpatients treated for diabetes, dipeptidyl peptidase-4 inhibitors (29%) and antihypertensive, β-blocking and renin-angiotensin system blocking drugs (32%) were the most prescribed antidiabetics and non-antidiabetics in all ages, respectively. The number of prescribed antidiabetic agents did not increase with age, whereas the total and non-antidiabetic numbers of medications prescribed increased linearly. For reduction of polypharmacy in older people with diabetes, we need to focus on non-antidiabetics.

Abstract
Community pharmacists may play a key role in promoting deprescribing of potential inappropriate medications (PIMs) that are highly prevalent among community-dwelling elderly with dementia. To characterize PIMs categories that need a special attention for dementia patients, in the present study, we analyzed the anonymized pharmacy claims data of patients aged 65 years and older (n = 333869) who visited nationwide 905 community-based pharmacies of Sugi Pharmacy Co., Ltd. during December 1-31, 2019. A dementia group was defined as patients who received typical dementia medications marketed in Japan, i.e., donepezil, galantamine, memantine or rivastigmine, and a non-dementia group was defined as patients who received no such medications. After propensity score matching on the basis of patients' age, gender and home healthcare insurance usage, the data of 11486 patients in each group were subjected to logistic regression analyses, to identify PIMs categories particularly important for dementia patients. Univariate analysis indicated that the proportions of dementia patients who received 1 and 2≤ of PIMs were significantly (p < 0.001) greater than those of non-dementia patients (odds ratios were 1.35 and 1.47, respectively). Multivariate analyses identified 5 categories of PIMs that were significantly more frequently prescribed in dementia patients, i.e., 'H2 blockers,' 'drugs for overactive bladder,' 'anti-diabetes drugs' and 'sulpiride' listed as PIMs categories for non-specific cases (adjusted odds ratios (aORs): 1.29, 1.91, 1.17, and 1.38, respectively), in addition to 'antipsychotics' listed only for dementia patients (aOR: 4.29). These results provide useful information to establish strategies for pharmacist-led deprescribing of PIMs in dementia patients.

Abstract
Background: Inappropriate medication use is common around the world, particularly among older patients, and, despite potentially being preventable, often leads to adverse clinical and economic outcomes. However, there is a dearth of information regarding this prominent issue in China. Objectives: To evaluate the extent to which the physician can correctly identify potentially inappropriate medication (PIM) in older patients and to understand physicians’ attitudes towards improving PIM knowledge. Methods: An online, cross-sectional survey was conducted anonymously among practicing physicians in China from November through December 2020. Knowledge of PIM was accessed using seven clinical vignettes covering a wide variety of therapeutic areas. Source of information and perceived barriers regarding PIM were also evaluated. We performed the ordinary least square regression analysis to understand the potential factors related to physicians’ knowledge of PIM. Results: A total of 597 study participants were included in the analysis. More than half of them had never heard of any screening tool for PIMs (n = 328, 54.9%) and the most frequently acknowledged tool was the China PIM Criteria (n = 259, 43.4%). For the seven clinical vignettes testing physicians’ knowledge on the medications that should be generally avoided in older patients, the mean score was 2.91 points out of 7 (SD: 1.32), with the median score of three points (IQR: 2–4). Only one-third of the respondents were feeling confident when prescribing for older patients (n = 255, 35.08%). Package inserts have been used as the major source of PIM information (always, n = 177, 29.65%; frequently, n = 286, 47.91%). Perceived barriers to appropriate prescribing include polypharmacy (n = 460, 77.05%), lack of formal education on prescribing for the older patients (n = 428, 71.69%). Conclusion: In this online survey evaluating physicians’ ability to detect PIM for older patients, approximately 40% of PIM were recognized, suggesting an insufficient level of knowledge about appropriate prescribing.

Abstract
BACKGROUND Much of the knowledge on the use of potentially inappropriate medications (PIM) in older adults is derived from cross-sectional studies, with little known about the risk factors over time. AIM Longitudinal analysis was applied to estimate the occurrence and risk factors of PIM use among older adults in a 10-year follow-up. METHOD Longitudinal study with 418 older adult residents of a capital city of Central-West Brazil. The PIM were classified according to the Beers criteria 2019. The usage rate was calculated at baseline (2008) and at the 10-year follow-up moment (2018). Analysis of predictors (sociodemographic, self-rated health, hospitalization, number of comorbidities, polypharmacy, diabetes, hypertension, hypercholesterolemia and nutritional status) was performed using Generalized Estimating Equation (GEE) models. RESULTS Mean age at baseline was 70.6 years (SD 7.1) and 76% were women; 221 older adults took part in the follow up. The rate of PIM use was 50.4% at baseline and 57.5% at the 10-year follow-up. Multiple analysis showed that PIM use in the cohort was statistically higher in the older adults with a history of hospitalization (RRadj 1.20; 95% CI 1.01-1.40), with three or more diseases (RRadj 1.41; 95% CI 1.14-1.74), with polypharmacy (RRadj 1.81; 95% CI 1.47-2.24) and with diabetes mellitus (RRadj 1.24; 95% CI 1.05-1.47). CONCLUSION A high level of potentially inappropriate medication use was observed, reaching 50% of the older adults, with a 7% increase in the prevalence over the 10-year follow-up period. Hospitalization, multimorbidities, polypharmacy and diabetes mellitus were associated with the use of these medications. Interventions for surveillance of the deprescribing process need to be encouraged to avoid potential harm caused by the use of medications.

[PMID: 35814333 PMCID: PMC9260603 DOI: 10.1177/20420986221100117] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Accepted: 04/26/2022] [Indexed: 11/15/2022] Open
Abstract
In the context of an ageing population, the burden of disease and medicine use is
also expected to increase. As such, medicine safety and preventing avoidable
medicine-related harm are major public health concerns, requiring further
research. Potentially suboptimal medicine regimens is an umbrella term that
captures a range of indicators that may increase the risk of medicine-related
harm, including polypharmacy, underprescribing and high-risk prescribing, such
as prescribing potentially inappropriate medicines. This narrative review aims
to provide a background and broad overview of the patterns and implications of
potentially suboptimal medicine regimens among older adults. Original research
published between 1990 and 2021 was searched for in MEDLINE, using key search
terms including polypharmacy, inappropriate prescribing, potentially
inappropriate medication lists, medication errors, drug interactions and drug
prescriptions, along with manual checking of reference lists. The review
summarizes the prevalence, risk factors and clinical outcomes of polypharmacy,
underprescribing and potentially inappropriate medicines. A synthesis of the
evidence regarding the longitudinal patterns of polypharmacy is also provided.
With an overview of the existing literature, we highlight a number of key gaps
in the literature. Directions for future research may include a longitudinal
investigation into the risk factors and outcomes of extended polypharmacy,
research focusing on the patterns and implications of underprescribing and
studies that evaluate the applicability of tools measuring potentially
inappropriate medicines to study settings.

The Effectiveness and Adverse Events of Amitriptyline and Aripiprazole in Very Elderly Patients With BMS. FRONTIERS IN PAIN RESEARCH 2022; 3:809207.

Abstract
Burning mouth syndrome (BMS) is defined by chronic oral burning sensations without any corresponding abnormalities. Besides amitriptyline, aripiprazole has been reported as a possible medication to manage BMS. However, especially for elderly patients, the adverse events of these medications would be a problem. The aim of the present study was to investigate the differences in the effectiveness and adverse events of amitriptyline and aripiprazole in very elderly patients with BMS. This is a retrospective comparative study of 80 years old and older patients with BMS who were initially treated with amitriptyline or aripiprazole and who were new outpatients of our department from April 2017 to March 2020. All clinical data, including sex, age, comorbid physical diseases, comorbid psychiatric disorders, the prescribed doses (initial, maximum, and effective dose), prognosis, and adverse events, were collected from their medical charts. Each medication was selected considering their medical history. Amitriptyline was prescribed in 13 patients (11 women, 82.3 ± 2.1 years old) and aripiprazole was prescribed in 27 patients (26 women, 84.2 ± 3.8 years old). There were no significant between-group differences in sex, age, duration of illness, pain intensity, salivation, and psychiatric comorbidity at the first examination. Amitriptyline clinically improved more patients (7 patients, 53.8%) with the effective dose of 10 (7.5, 15.0) mg than aripiprazole (11 patients, 40.7%) of which the effective dose was 1.0 (0.5, 1.5) mg, although there were no significant between-group differences. The adverse events of amitriptyline were found in 9 patients (69.2%) and most patients had constipation (46.2%). For aripiprazole, 7 patients (25.9%) showed adverse events, most of them reported sleep disorder (11.1%). Amitriptyline had significantly longer duration taking medication (p = 0.021) and lower discontinuation (p = 0.043) despite of higher occurrence rate of adverse events (p = 0.015) compared to aripiprazole. These results suggest that both psychopharmacotherapies with a low dose of amitriptyline and aripiprazole are effective for the very elderly patients with BMS. Furthermore, aripiprazole may have some advantages in the adverse events compared to amitriptyline; however, the low dose amitriptyline monotherapy may have more benefit in the effectiveness and tolerability over prudent collaboration with primary physicians.

Abstract
Background Drug-drug interactions (DDIs) can cause treatment failure and serious adverse drug reactions, leading to morbidity and mortality. Due to their significant effects on the patient’s health, community pharmacists (CPs) competence in detecting and preventing these interactions is essential to provide optimal health services. Thus, this study aimed to explore the performance of the CPs in situations involving the presence of potential DDIs. Methods A cross-sectional, simulated patient study was conducted in 235 community pharmacies in the Khartoum locality. Two scenarios were used to evaluate the performance of the CPs. Ten final year B. Pharm. students were selected to act as simulated patients (SPs); they were trained for two weeks to familiarize their roles. All encounters were documented immediately after leaving the pharmacy by the SPs in the data collection form. Results All planned SPs visits were completed, resulting in 470 visits. None of the CPs asked about the patients’ medication history in both scenarios. After the SPs provided information about the drug used currently by the patient, 13.6% and 23.4% of the CPs had identified the potential DDIs in scenario 1 and scenario 2, respectively. In scenario 1, 59.4% distinguished the interaction of simvastatin with both drugs, while, in scenario 2, 74.5% recognized the interaction of warfarin with both drugs. In identifying DDIs, around half of the CPs were dependent on their knowledge or using drug interaction checker programs. The most common intervention made by the CPs was referring the patient to the prescriber (56.3% CPs in scenario 1 and 60% CPs in scenario 2). Conclusion CPs practice in identifying and managing potential DDIs was poor. The current CPs practices need substantial improvement. Therefore, professional education and the use of software programs in community pharmacies should be encouraged.

Abstract
Background Older age increases the likelihood of chronic diseases and polypharmacy with the likelihood of potentially inappropriate medications (PIMs) in secondary and tertiary care levels, but in the primary care settings of Thailand there still is a need for more evidence. This study aimed to examine the prevalence of PIM in primary care settings, and to identify factors that influence the use of PIM. Methods A cross-sectional retrospective study was conducted in 2017. Eight primary care units from four regions of Thailand were randomly selected. People aged ≥ 60 years in the eight units were studied as participants. The List of Risk Drugs for Thai Elderly (LRDTE) was used as the reference. Multivariate logistic regression was carried out to identify factors that influence. Results A total of 4,848 patients aged ≥60 years with 20,671 prescriptions were studied. The mean age was 70.7±8.3 years for males, and 61.2% for females. A little more than 5% (5.1%) had ≥ 3 chronic diseases and 15.0% received polypharmacy (≥5 medications). The prevalence of prescriptions with PIMs was 65.9%. The most frequent PIMs were antidepressants: amitriptyline (28.1%), antihistamines: dimenhydrinate (22.4%) and chlorpheniramine maleate (CPM) (11.2%); and Benzodiazepines: lorazepam (6.5%). Three factors that significantly influenced prescribing of PIMs were polypharmacy (adjusted OR 3.51; 95% CI 2.81-4.32), having ≥3 chronic diseases (adjusted OR 1.44; 95% CI 1.04-2.01), and age ≥75 years (adjusted OR 1.18; 95% CI 1.01-1.38). Conclusion More than two-thirds of elderly Thai patients in the primary care settings were prescribed PIMs. Multidisciplinary prescription review and PIM screening in patients aged ≥75 years who have ≥3 chronic diseases or polypharmacy should be implemented in primary care and supportive computerized PIMs alert system is needed.

Abstract
BACKGROUND The use of potentially inappropriate medications (PIMs) is common in older adults and is associated with potential negative consequences, such as falls and cognitive decline. Our objective was to investigate measurable patient factors associated with new outpatient prescribing of potentially inappropriate medications in older multimorbid adults already using multiple medications. METHODS In this retrospective US cohort study, we used linked Medicare pharmacy and medical claims and electronic health record data from a large healthcare system in Massachusetts between 2007 and 2014. We identified patients aged ≥65 years with an office visit who had not been prescribed or used a PIM in the prior 180 days. PIMs were defined using 2019 Beers criteria of the American Geriatrics Society. To specifically evaluate factors in patients with polypharmacy and multimorbidity, we selected those who filled medications for ≥90 days (i.e., chronic use) from ≥5 pharmaceutical classes in the prior 180 days and had ≥2 chronic conditions. Multivariable Cox regression analysis was used to estimate the association between baseline demographic and clinical characteristics on the probability of being prescribed a PIM in the 90-day follow-up period. RESULTS In total, we identified 17,912 patients aged ≥65 years with multimorbidity and polypharmacy who were naïve to a PIM in the prior 180 days. Of those, 10,497 (58.6%) were female, and mean age was 78 (SD = 7.5). On average, patients had 5.1 (SD = 2.3) chronic conditions and previously filled 6.1 (SD = 1.4) chronic medications. In total, 447 patients (2.5%) were prescribed a PIM during the 90-day follow-up. Male sex (adjusted hazard ratio (HR) = 1.29; 95%CI: 1.06-1.57), age (≥85 years: HR = 0.75, 95%CI: 0.56-0.99, 75-84 years: HR = 0.87, 95%CI: 0.71-1.07; reference: 65-74 years), ambulatory visits (18-29 visits: HR = 1.42, 95%CI: 1.06-1.92; ≥30 visits: HR = 2.12, 95%CI: 1.53-2.95; reference: ≤9 visits), number of prescribing orders (HR = 1.02, 95%CI: 1.01-1.02 per 1-unit increase), and heart failure (HR = 1.38, 95%CI: 1.07-1.78) were independently associated with being newly prescribed a PIM. CONCLUSION Several demographic and clinical characteristics, including factors suggesting lack of care coordination and increased clinical complexity, were found to be associated with the new prescribing of potentially inappropriate medications. This knowledge could inform the design of interventions and policies to optimize pharmacotherapy for these patients.

Association of Self-Reported Medication Adherence with Potentially Inappropriate Medications in Elderly Patients: A Cross-Sectional Pilot Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17165940. [PMID: 32824284 PMCID: PMC7460224 DOI: 10.3390/ijerph17165940] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/12/2020] [Accepted: 08/14/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND Polypharmacy (PP) and potentially inappropriate medications (PIMs) cause problematic drug-related issues in elderly patients; however, little is known about the association between medication adherence and PP and PIMs. This study evaluated the association of self-reported medication adherence with PP and PIMs in elderly patients. METHODS A cross-sectional pilot study was conducted using data collected from electronic medical records of 142 self-administering patients aged ≥65 years, excluding emergency hospitalization cases. Self-reported medication adherence was assessed using the visual analogue scale (VAS). RESULTS Of the 142 patients, 91 (64.1%) had PP and 80 (56.3%) used at least one PIM. In univariate analysis, patients with a VAS score of 100% had a significantly higher number of female patients and ≥1 PIM use compared to other patients. We found no association between the VAS score and PP. In multivariable analysis, the use of PIMs was significantly associated with a VAS score of 100% (odds ratio = 2.32; 95% confidence interval = 1.16-4.72; p = 0.017). CONCLUSIONS Use of PIMs by elderly patients is significantly associated with self-reported medication adherence. Pharmacists should pay more attention to prescribed medications of self-administering elderly patients in order to improve their prescribing quality.
