Polypharmacy among the elderly: a population-based study

Prevalence of polypharmacy use and association with mortality: a cohort study of elderly people in Southern Brazil, 2014-2017

OBJECTIVE

To characterize prevalence of polypharmacy use and its association with mortality in elderly people.

METHODS

Prospective cohort (2014 to 2017), with non-institutionalized individuals aged 60 years or over, living in Pelotas, Rio Grande do Sul, Brazil. Association between polypharmacy and mortality was analyzed using Cox regression. Hazard ratios (HR) and their respective 95% confidence intervals (95%CI) were calculated, following the Cox proportional hazards model. Interaction between age groupand multimorbidity was considered to be statistically significant when p-value<0.100.

RESULTS

Results: Polypharmacy prevalence was 36.1% (95%CI 33.7; 38.6), being higher as age group increased (29.8% in those aged 60-69; 41.3% in those aged 70-79). and 47.8% inthose aged 80 years and over). In the adjusted analysis, risk of mortality was 62% higher among elderly people using polypharmacy (HR 1.62; 95%CI 1.10; 2.39), without interaction between age group (p-value 0.750) and multimorbidity (p-value 0.312). Thesurvival analysis demonstrated that the probability of survival was lower in elderly people using polypharmacy (85.6%).

CONCLUSION

Polypharmacy prevalence was found to be higher as age group increased and elderly people using polypharmacy had higher risk of mortality, regardless of age group and presence of multimorbidity.

Assessment of Geriatric Problems and Risk Factors for Delirium in Surgical Medicine: Protocol for Multidisciplinary Prospective Clinical Study

BACKGROUND

An aging population in combination with more gentle and less stressful surgical procedures leads to an increased number of operations on older patients. This collectively raises novel challenges due to higher age heavily impacting treatment. A major problem, emerging in up to 50% of cases, is perioperative delirium. It is thus vital to understand whether and which existing geriatric assessments are capable of reliably identifying risk factors, how high the incidence of delirium is, and whether the resulting management of these risk factors might lead to a reduced incidence of delirium.

OBJECTIVE

This study aimed to determine the frequency and severity of geriatric medical problems in elective patients of the Clinics of Oral and Maxillofacial Surgery, Vascular Surgery, and Orthopedics, General Surgery, and Trauma Surgery, revealing associations with the incidence of perioperative delirium regarding potential risk factors, and recording the long-term effects of geriatric problems and any perioperative delirium that might have developed later the patient's life.

METHODS

We performed both pre- and postoperative assessments in patients of 4 different surgical departments who are older than 70 years. Patient-validated screening instruments will be used to identify risk factors. A geriatric assessment with the content of basal and instrumental activities of daily living (basal activities of daily living [Katz index], instrumental activities of daily living [Lawton and Brody score], cognition [6-item screener and clock drawing test], mobility [de Morton Mobility Index and Sit-to-Stand test], sleep [Pittsburgh Sleep Quality Index and Insomnia Severity Index/STOP-BANG], drug therapy [polypharmacy and quality of medication, Fit For The Aged classification, and anticholinergic burden score], and pain assessment and delirium risk (Delirium Risk Assessment Tool) will be performed. Any medical problems detected will be treated according to current standards, and no intervention is planned as part of the study. In addition, a telephone follow-up will be performed 3, 6, and 12 months after discharge.

RESULTS

Recruitment started in August 2022, with 421 patients already recruited at the time of submission. Initial analyses of the data are to be published at the end of 2024 or the beginning of 2025.

CONCLUSIONS

In the current study, we investigate whether the risk factors addressed in the assessment are associated with an increase in the delirium rate. The aim is then to reduce this comprehensive assessment to the central aspects to be able to conduct targeted and efficient risk screening.

Physicians and hospital pharmacists' knowledge, attitudes, and practices towards polypharmacy in older patients with chronic diseases

This web-based cross-sectional study aimed to evaluate the knowledge, attitudes, and practices of physicians and hospital pharmacists towards polypharmacy in older adult patients with chronic diseases in China. This study enrolled 374 physicians and pharmacists (270 females, 92 physicians) in 20 Chinese provinces between December 2022 and March 2023. The knowledge, attitude, and practice scores were 12.65 ± 2.05 (possible range, 0-18), 29.07 ± 2.68 (possible range, 7-35), and 26.16 ± 5.56 (possible range, 7-35), respectively. Working as a hospital pharmacist (vs. physician) was independently associated with adequate knowledge (OR = 2.190; 95% CI = 1.291-2.713; P = 0.004). Working in a tertiary hospital (OR = 4.296; 95% CI = 1.390-13.272; P = 0.011) was independently associated with a positive attitude. Knowledge score (OR = 1.176; 95%CI = 1.038-1.333; P = 0.011), hospital pharmacist (OR = 0.276; 95% CI = 0.137-0.557; P < 0.001), master's degree or higher (OR = 1.754; 95% CI  = 1.011-3.045; P = 0.046) and senior professional title (OR = 2.020; 95% CI = 1.032-3.952; P = 0.040) were independently associated with proactive practice toward polypharmacy in older adults. Physicians and hospital pharmacists had favorable knowledge, positive attitudes, and proactive practice toward polypharmacy. In conclusion, enhancing knowledge through continuous education, promoting interprofessional collaboration, educating patients, and conducting regular evaluations for quality improvement are necessary to improve the KAP of healthcare professionals toward polypharmacy in older adults.

Relationship between the number of drugs used during percutaneous coronary intervention and adverse events in patients with chronic coronary syndrome: Analysis of CLIDAS database

Background

Polypharmacy is associated with an increased risk of adverse events due to the higher number of drugs used. This is particularly notable in patients with chronic coronary syndrome (CCS), who are known to use a large number of drugs. Therefore, we investigated polypharmacy in patients with CCS, using CLIDAS, a multicenter database of patients who underwent percutaneous coronary intervention.

Method and results

Between 2017 and 2020, 1411 CCS patients (71.5 ± 10.5 years old; 77.3 % male) were enrolled. The relationship between cardiovascular events occurring during the median follow-up of 514 days and the number of drugs at the time of PCI was investigated. The median number of drugs prescribed was nine. Major adverse cardiovascular events (MACE), defined as cardiovascular death, myocardial infarction, stroke, heart failure, transient ischemic attack, or unstable angina, occurred in 123 patients, and all-cause mortality occurred in 68 patients. For each additional drug, the adjusted hazard ratios for MACE and all-cause mortality increased by 2.069 (p = 0.003) and 1.102 (p = 0.010). The adjusted hazard ratios for MACE and all-cause mortality were significantly higher in the group using nine or more drugs compared to the group using eight or fewer drugs (1.646 and 2.253, both p < 0.001).

Conclusion

This study showed that an increase in the number of drugs used for CCS may be associated with MACE and all-cause mortality. In patients with CCS, it might be beneficial to minimize the number of medications as much as possible, while managing comorbidities and using guideline-recommended drugs.

A Review of Risk Factors for Polypharmacy: Age, Level of Education, and Physician's Attitude

Polypharmacy, a growing public health and economic concern, is particularly common among the elderly due to the high prevalence of multimorbidity, such as dementia and stroke, which necessitates complex treatment regimens. While commonly understood as taking five or more medications, definitions of polypharmacy are varied and may be misleading in clinical practice. This research examines factors such as a country's expenditure on health and education, age, and clinicians' holistic approaches to compare the prevalence of polypharmacy across different groups. The review included documentary research through PubMed, Scopus, and Google Scholar databases and search engines, resulting in seven selected sources. The average year of publication was 2020 (median: 2020; standard deviation: 1.63; range: 2018 to 2023). The level of polypharmacy was found to be significantly dependent on per capita expenditure on education (R2 = -0.79; F(6) = -3.11; p = 0.02) and health (R2 = -0.76; F(6) = -2.88; p = 0.03). Countries with higher spending in these areas had a lower proportion of participants with polypharmacy. Additionally, patients' quality of life (QoL) is closely tied to the amount of medication they consume, highlighting the need for physicians to avoid unnecessary prescriptions. Patients impacted by polypharmacy often lack knowledge about their diseases and medications, negatively affecting their QoL and compliance. To develop effective treatment plans and improve clinical practice, doctors should consider these risk factors, prioritize patient education, and utilize innovative technologies to support patients. While polypharmacy is sometimes unavoidable and necessary, this approach could in some cases help mitigate the challenges and risks posed by inappropriate polypharmacy and enhance patients' QoL. Furthermore, policymakers should consider increasing spending on education and healthcare, as this may resolve clinical and economic problems related to the issue.

Multiple geriatric syndromes in community-dwelling older adults in China

This study aims to assess the prevalence of geriatric syndromes and identify factors associated with multiple geriatric syndromes in community-dwelling older adults in China. We utilized a convenience sampling method to recruit older adults and from one rural and one urban community in Chengdu, China, from October 2022 to March 2023. A total of 706 older adults aged 60 years or older were included. Ten geriatric syndromes were investigated including two mental disorders: depressive symptoms, cognitive impairment; and eight somatic disorders: pain, falls, sleep disturbance, constipation, polypharmacy, multimorbidity, malnutrition and frailty. Multiple geriatric syndromes were defined as an individual having two or more geriatric syndromes. The data obtained were analysed using descriptive statistics. The independent risk factors for multiple geriatric syndromes were assessed using a logistic regression model. This study found that 90.5% of the participants had at least one geriatric syndrome, with 72.8% experiencing multiple geriatric syndromes. The top four geriatric syndromes in our study were polypharmacy (58.5%), malnutrition/at risk of malnutrition (43.1%), multimorbidity (42.1%), and frailty/prefrailty (34.3%). Of the older adults, 368(52.1%) had only somatic disorders, 18(2.5%) had only mental disorders and 253 (35.8%) had somatic-mental disorders. According to the logistic regression analysis, residence, age, marriage, BMI, and self-related health were significantly associated with multiple geriatric syndromes among older adults. This study highlights that multiple geriatric syndromes are prevalent among community-dwelling older adults in China, and underscores the significance of certain demographic factors in their occurrence. Future longitudinal studies are needed to establish the temporal relationship between multiple geriatric syndromes and these demographic factors, as well as to explore causal relationships and effective prevention strategies for geriatric syndrome.

Management pattern and medication-related harms and its predictors in colorectal cancer patients: an institutional-based retrospective study

Introduction

Data on colorectal cancer (CRC) patients' thorough management practices and medication-related harms (MRH) are scarce. This study's aim was to investigate the MRHs in patients receiving CRC chemotherapy at the comprehensive specialized hospital of the University of Gondar (UoGCSH).

Methods

A registry-based retrospective cohort study was conducted on CRC patients at the UoGCSH during 2017-2021. From February to May 2022, medical records were reviewed using a pretested data collection tool to collect socio-demographic and disease-related characteristics, MRHs, and medication regimens. MRHs occurrence and adverse drug reactions (ADRs) severity were assessed using standard guidelines and protocols. Version 16/MP of STATA for Windows was used for the analysis. Independent predictors of MRHs were investigated using logistic regression analysis. A p-value ≤0.05 was used to determine an independent variable's statistical significance.

Results

One hundred forty three CRC patients were included, with a mean age of 49.9 ± 14.5 years. About 32.9% and 33.6% had stage II and III cancer, respectively. Significant patients had co-morbidities (15.4%) and complications (13.3%). Fluorouracil (5-FU)-based regimens were given to more than half (56%) of the patients. MRHs were found in 53.1% of the patients, with a mean of 2.45 ± 1.37 MRHs. The most common MRHs were the need for additional drug therapy, sub-therapeutic dose, DDIs, and ADRs. Being on stage IV (AOR = 27.7, 95% CI = 3.85-199.38, p = 0.001), having co-morbidity (AOR = 7.42, 95% CI = 1.80-30.59, p = 0.018) and having complication (AOR = 11.04, 95% CI = 1.72-70.95, p = 0.011) and treated with five or more drugs (AOR = 2.54, 95% CI = 1.07-6.07, p = 0.035) were independent predictors of MRHs.

Conclusion

A fluorouracil-based treatment regimen was most frequently used. MRHs were found in nearly half of CRC patients. Furthermore, MRHs were significantly associated with cancer stage, comorbidity and complication status, and the number of medications used. Because MRHs are common, improving clinical pharmacy services is critical for optimizing drug therapy in CRC patients.

[Management of pruritus in the elderly]

BACKGROUND

Chronic pruritus (CP), a frequent (20.3%) symptom in the elderly, increases with age. It has a significant impact on the quality of life, ranking among the 50 most burdensome diseases worldwide (Global Burden of Disease Study).

OBJECTIVES

The aim is to provide an overview of the symptom CP in the elderly and to improve differentiation of underlying conditions and management of this entity.

MATERIALS AND METHODS

A literature search in PubMed was performed, using the terms 'pruritus', 'elderly' and 'gerontodermatology'.

RESULTS

The main causes of CP in the elderly are the physiologic aging process (xerosis cutis, immunosenescence, neuropathy), the increase in potentially pruritic diseases with increasing age (diabetes mellitus, chronic renal failure), and polypharmacy. Therapeutic options relate to causes, severity of pruritus, and individual patient factors (multimorbidity, impaired organ function). The recently updated S2k guideline 'Diagnosis and therapy of chronic pruritus' is helpful.

CONCLUSION

CP in the elderly is challenging for both patients and physicians. Not only the difficulty of identifying the underlying cause, but the complexity of treatment and its tolerability and practicability determines these patients' further burden.

Incidence and risk factors for polypharmacy among elderly people assisted by primary health care in Brazil

BACKGROUND

Polypharmacy is recognized as a global public health problem and one of the greatest challenges related to the aging population. Few studies have investigated the incidence and risk factors for polypharmacy among elderly individuals. These studies provided important information on the issue but were developed in high-income countries. This study investigates the incidence and risk factors for polypharmacy among elderly people assisted by primary health care over a period of 11 years.

METHODS

This was a census-based prospective longitudinal study that included people aged 60 years or older living in a small municipality in the state of Rio Grande do Sul, Brazil. The baseline occurred in 2010 and the second wave of the study occurred in 2021. The study population consisted of elderly individuals who did not use polypharmacy at baseline and were reinterviewed in 2021 (N = 128). Data collection in the first and second waves was performed through a household survey using a structured questionnaire. The dependent variable was polypharmacy, defined as the simultaneous use of 5 or more drugs. The independent variables included sociodemographic, health and functionality factors. For multivariate analyses, Poisson regression with robust variance was used, estimating the relative risk and 95% confidence intervals.

RESULTS

The incidence of polypharmacy was 46.1% in the 11-year period. The highest number of health problems was a risk factor for polypharmacy (RR = 1.177; 95% CI 1.093-1.267).

CONCLUSIONS

The incidence of polypharmacy among elderly people assisted in primary health care in Brazil is high. The number of diseases is a risk factor for polypharmacy. These results have implications for future primary health care practices and may support the development of policies, actions and services aimed at reducing polypharmacy and promoting the rational use of drugs in the population at higher risk.

Prevalence, trends, and characteristics of polypharmacy among US pregnant women aged 15 to 44 years: NHANES 1999 to 2016

Polypharmacy has become a major health issue for pregnant woman due to the increased trend of medication use during pregnancy. However, data on medication use in pregnancy are limited since pregnant women are rarely included in clinical trials. Our study aimed to investigate the trends of and characteristics associated with polypharmacy among pregnant women in the US. This study was conducted using data from The National Health and Nutrition Examination Survey in the US. Nine The National Health and Nutrition Examination Survey cycles between 1999 and 2016 were used to identify pregnant women aged 15 to 44 years. Polypharmacy was defined as more than 1 medication prescription used during pregnancy. Descriptive statistics were used to report the prevalence and trends of polypharmacy. Multivariable logistic regression models were used to evaluate characteristics associated with polypharmacy among US pregnant women. Among 3,350,983 US pregnant women, about 7.4% of them (247,525) experienced polypharmacy. The prevalence of polypharmacy increased from 2.8% (1999-2000) to 10.0% (2015-2016) (P < .01) over-the time period examined in this study. Pregnant women were less likely to have experienced polypharmacy than were nonpregnant women (7.4% vs 23.5%, P < .01). Levothyroxine and albuterol were 2 prescriptions commonly taken by pregnant women. Pregnant women who were non-Hispanic white (P < .05) or had asthma (P < .05) or diabetes (P < .01) were more likely to report polypharmacy. Regarding personal characteristics, women with a poor or fair self-reported general health condition (odds ratio: 5.12, 95% confidence interval: 1.23-21.34) and those with chronic conditions (odds ratio: 6.91, 95% confidence interval: 3.08-15.50) were found to be associated with polypharmacy. An increased trend of polypharmacy was found in the US from 1999 to 2016. Non-Hispanic white pregnant women with a poor health status and chronic diseases were at an increased risk of polypharmacy.

Limiting Factors in Implementing Pharmacovigilance Principles in the Elderly

The overarching aim of pharmacovigilance is to ensure the safe and effective usage of medication across the population and optimise medicines through holistic considerations. However, within the heterogeneous elderly population, several unique factors are at play, limiting the ability of clinicians to fulfil this aim. A matured physiology influencing the response and effects of drugs, increased polypharmacy enabling drug-drug interactions, and greater consumption of concurrent herbal medicines predispose patients to harmful drug events. This increasingly multimorbid subpopulation requires complex pharmaceutical regimens encouraging inappropriate prescribing and medicine non-adherence leading to suboptimal therapy. Furthermore, restrictive practices in clinical trials commonly exclude elderly patients creating disparities from expected findings within a real-world setting. These issues create an environment where elderly patients are at a heightened risk of adverse drug events and clinicians are forced to make significant decisions from limited information. With projections showing that this demographic will continue growing in size, the true burden of these limiting factors is yet to be realised.

Are there socioeconomic inequalities in polypharmacy among older people? A systematic review and meta-analysis

BACKGROUND

Socioeconomic status (SES) may influence prescribing, concordance and adherence to medication regimens. This review set out to investigate the association between polypharmacy and an individual's socioeconomic status.

METHODS

A systematic review and meta-analyses of observational studies was conducted across four databases. Older people (≥ 55 years) from any healthcare setting and residing location were included. The search was conducted across four databases: Medline (OVID), Web of Science, Embase (OVID) and CINAHL. Observational studies from 1990 that reported polypharmacy according to SES were included. A random-effects model was undertaken comparing those with polypharmacy (≥ 5 medication usage) with no polypharmacy. Unadjusted odds ratios (ORs), 95% confidence intervals (CIs) and standard errors (SE) were calculated for each study.

RESULTS

Fifty-four articles from 13,412 hits screened met the inclusion criteria. The measure of SES used were education (50 studies), income (18 studies), wealth (6 studies), occupation (4 studies), employment (7 studies), social class (5 studies), SES categories (2 studies) and deprivation (1 study). Thirteen studies were excluded from the meta-analysis. Lower SES was associated with higher polypharmacy usage: individuals of lower educational backgrounds displayed 21% higher odds to be in receipt of polypharmacy when compared to those of higher education backgrounds. Similar findings were shown for occupation, income, social class, and socioeconomic categories.

CONCLUSIONS

There are socioeconomic inequalities in polypharmacy among older people, with people of lower SES significantly having higher odds of polypharmacy. Future work could examine the reasons for these inequalities and explore the interplay between polypharmacy and multimorbidity.

Difficulties in the use of medications by elderly people followed up in a cohort study in Southern Brazil

OBJECTIVE

This study aimed to assess the need for help by elderly people to take their medications, the difficulties related to this activity, the frequency of forgotten doses, and factors associated.

METHODS

Cross-sectional study conducted with a cohort of elderly people (60 years and over - "COMO VAI?" [How do you do?] study), where the need for help to properly take medication and the difficulties faced in using them were evaluated. The Poisson regression model was used to estimate the crude and adjusted prevalence ratios (PR) of the outcomes and respective 95% confidence intervals according to the characteristics of the sample.

RESULTS

In total, 1,161 elderly people were followed up. The prevalence of participants who reported requiring help with medication was 15.5% (95%CI 13.5-17.8), and the oldest subjects, with lower educational levels, in worse economic situations, on four or more medications and in bad self-rated health were the ones who needed help the most. Continuous use of medication was reported by 83.0% (95%CI 80.7-85.1) of the sample and most participants (74.9%; 95%CI 72.0-77.5) never forgot to take their medications.

CONCLUSION

The need for help to use medications was shown to be influenced by social and economic determinants. Studies assessing the difficulties in medication use by the elderly are important to support policies and practices to improve adherence to treatment and the rational use of medications.

Quanto à posologia, 83 (80,95%) sabiam como tomar a medicação e 41 (39,05%) não sabiam como proceder em caso de esquecimento, 51 (53,54%) não conheciam os efeitos colaterais e 30 (28,58%) necessitavam de maiores informações sobre o tratamento. Conclusões: Conclui-se que existe uma lacuna entre o conhecimento do paciente idoso e o conhecimento a respeito dos seus medicamentos/tratamento, necessitando-se de maior atenção aos aspectos farmacológicos do tratamento e ao fornecimento de informação de forma clara, didática e objetiva.

Polypharmacy among older adults in Brazil: Association with sociodemographic factors and access to health services

Background

Polypharmacy is common among older adults and is of public health concern, since pharmacological therapy influences the quality of care for older individuals. Few studies have addressed its prevalence and correlates in low or middle-income countries. Objective: To evaluate the prevalence of polypharmacy in a representative sample of the Brazilian older population and its association with sociodemographic conditions and factors related to access to health services.

Methods

Cross-sectional study with data from the last National Health Survey, conducted in 2019. The dependent variable was polypharmacy (five or more medications) and independent variables were: sociodemographic characteristics, general health conditions and access to health services indicator.

Results

The prevalence of polypharmacy was 19.2%. Polypharmacy was higher among those aged 80 years and over compared to those aged 60-69 years (prevalence ratio (PR) 1.47; 95% CI: 1.30; 1.66); individuals with complete elementary education (PR 1.35; 95% CI: 1.13; 1.60) versus those who did not go to school; with 3+ chronic diseases (PR 11.14; 95% CI: 7.94; 15.63); those with limitations in basic activities of daily life (PR 1.49; 95% CI: 1.35; 1.63) and possession of private medical health insurance (PR 1.32; 95% CI 1.19; 1.46). Being in a marital relationship was inversely associated with polypharmacy (PR 0.88; 95% CI: 0.80; 0.96).

Conclusion

Polypharmacy affects a significant proportion of the Brazilian older population and is associated with sociodemographic factors and access to health services.

Nursing protocol in chronic kidney disease prevention in older adults in primary care

OBJECTIVES

to develop a protocol for Nursing Process operationalization in approaching older adults with vulnerability to chronic kidney disease in Primary Health Care, based on Neuman's stressors.

METHODS

a methodological study, carried out in two stages: 1) synthesis of evidence using an inductive strategy (mixed method study) and 2) protocol development to support the nursing process operationalization with older adults enrolled in a Basic Health Unit, using a deductive strategy (Neuman's stressor concepts, NANDA, NIC, and NOC taxonomies, Risner's line of reasoning, and cross-mapping), described according to A Step-by-Step Guide to Developing Protocols.

RESULTS

102 older adults participated, and 17 diagnoses, 34 interventions and 26 nursing outcomes were identified.

CONCLUSIONS

the protocol developed is a technology that makes it possible to operationalize the Nursing Process, based on Neuman's stressors and on taxonomy, conceptual and care frameworks, guiding care and nursing records.

Communication about medication management during patient-physician consultations in primary care: a participant observation study

OBJECTIVE

To explore communication about medication management during annual consultations in primary care.

DESIGN

passive participant observations of primary care consultations.

SETTING

Two primary care centres in southern Sweden.

PARTICIPANTS

Consultations between 18 patients (over the age of 60 years) with chronic diseases and 10 general practitioners (GPs) were observed, audio-recorded, transcribed and analysed using content analysis.

RESULTS

Four categories emerged: communication barriers, striving for a shared understanding of medication management, evaluation of the current medication treatment and the plan ahead and behavioural changes in relation to medication management. Misunderstandings in communication, failure to report changes in the medication treatment and use of generic substitutes complicated mutual understanding and agreement on continued treatment. The need for behavioural changes to reduce the need for medication treatment was recognised but should be explored further.

CONCLUSION

Several pitfalls, including miscommunication and inaccurate medication lists, for safe medication management were identified. The purpose of annual consultations should be clarified, individual treatment plans could be used more actively during primary care consultations and efforts are needed to improve verbal communication and information continuity.

Clinical pattern and drug-related problems among colorectal cancer patients at oncology center in Ethiopia: A hospital-based study

Objective:

Despite the fact that cancer patients are highly susceptible to drug-related problems due to the effects of cytotoxic agents, data are limited due to a lack of studies on those patients. Hence, we aimed to investigate drug-related problems among patients diagnosed with colorectal cancer.

Method:

A registry-based cross-sectional study was conducted on colorectal cancer patients at the Felege Hiwot Comprehensive Specialized Hospital. Socio-demographic and disease-related characteristics, treatment regimens, and drug-related problems were recorded by reviewing medical records. Standard guidelines, protocols, and databases were used to evaluate the occurrence of drug-related problems and the severity of adverse drug reactions. For the analysis, Stata version 16/MP for Windows was used. Logistic regression analysis was employed to investigate the potential-associated factors of drug-related problems. A p-value ⩽ 0.05 was used to declare the statistical significance of each independent variable.

Results:

A total of 150 colorectal cancer patients were included, with a mean age of 51.4 ± 13.8 years. About 30% and 41.3% had stage II and stage III cancers, respectively. About three-quarters (73.8%) of the patients were given 5-fluorouracil-based combination regimens. The prevalence of drug-related problems was found to be 48.7%, with a mean of 2.12 ± 0.93 drug-related problems. In the Felege Hiwot Comprehensive Specialized Hospital, drug–drug interactions and adverse drug reactions were the most prevalent drug-related problems, which accounted for 50 (32.7%) and 49 (32%) cases, respectively. Being elderly (>50 years old) (p = 0.013), having co-morbidity (p = 0.001), and being on five or more medications (p = 0.002) were independent predictors of drug-related problems.

Conclusion:

Fluorouracil-based chemotherapy was the most frequently used treatment regimen. Almost, half of the colorectal cancer patients had one or more drug-related problems. About one-third of patients had adverse drug reactions and drug–drug interactions. Furthermore, age, co-morbidity status, and the number of medications used were significantly associated with drug-related problems. Clinical pharmacy services should be implemented to optimize drug therapy because the majority of colorectal cancer patients have one or more drug-related problems.

Beliefs and attitudes of residents, family members and healthcare professionals regarding deprescribing in long-term care: a qualitative study

BACKGROUND

Polypharmacy is prevalent among long-term care (LTC) residents and can cause significant morbidity. In 2018, we concluded a deprescribing pilot study that reduced potentially inappropriate medication use among LTC residents.

AIM

We sought to understand the experience and views of physicians, nurses, pharmacists, LTC residents and family members who participated in the pilot study.

METHOD

Qualitative semi-structured interviews were conducted with residents and families, a physician, pharmacist and pharmacy student, and licensed-practical nurses. Interviews were audio recorded, transcribed, and analyzed using an inductive thematic analysis approach.

RESULTS

Interviews with 13 participants yielded themes in 3 categories: (1) views about medication use in LTC and willingness to engage in deprescribing, (2) perceived barriers and enablers for deprescribing, and (3) impact of participating in deprescribing study. Participants were willing to engage in deprescribing; residents were motivated by physician suggestions, and family members prioritized quality of life in decision-making and wanted to be part of the decision-making process. Solutions to overcome barriers included assigning responsibility to identify deprescribing opportunities to pharmacists, scheduling rounds to enable face-to-face team discussions, and consulting families to provide missing medical history to inform deprescribing decisions. Participating in a deprescribing intervention resulted in improved healthcare professional (HCP) confidence and interprofessional collaboration, and caused continued practice change after the study.

CONCLUSION

Residents, families, and HCPs are concerned about problems associated with polypharmacy in LTC and are willing to consider deprescribing. Barriers to deprescribing in LTC exist but are not insurmountable. Results provide valuable insight into strategies to optimize deprescribing interventions within LTC.

Diferentes intervenções de fisioterapia na melhora da sensibilidade plantar e equilíbrio de idosas

Objetivo: comparar os efeitos de dois diferentes protocolos de fisioterapia no tratamento da sensibilidade plantar e equilíbrio em idosas da comunidade do município de Panambi. Métodos: ensaio clínico piloto, quantitativo e descritivo. As participantes responderam questionário sobre condições de saúde e autopercepção de sensibilidade plantar. Após, passaram por avaliação da sensibilidade plantar com estesiômetro Semmes-Weinstein. Foram selecionadas apenas idosas com sensibilidade diminuída. O equilíbrio foi avaliado através da Escala de Equilíbrio de Berg e teste Timed Up and Go. As 13 participantes selecionadas foram divididas em grupo sensibilidade plantar e grupo proprioceptivo, com a realização de 10 intervenções com cada grupo, com estímulo específico conforme alocação nos grupos. Após houve a reavaliação das participantes com estesiômetro, Escala de Equilíbrio de Berg e Timed Up and Go. As comparações das variáveis quantitativas foram realizadas através do teste t de Student, com nível de significância adotado de 5% (p<0,05). Resultados: 12 idosas concluíram o estudo, porém apenas cinco relataram perceber diminuição de sensibilidade plantar. As regiões plantares com maior perda de sensibilidade foram nos metatarsos, região lateral do pé e calcâneo. Já a região medial, apresentou menor perda sensorial. Após os treinos, ambos os grupos mostraram melhora estatisticamente significativa na sensibilidade plantar. Já no equilíbrio, o grupo sensibilidade plantar apresentou resultados estatisticamente significativos no teste Timed Up and Go e o grupo proprioceptivo na Escala de Equilíbrio de Berg. Conclusão: os treinos mostraram-se efetivos na sensibilidade plantar e equilíbrio das participantes, indicando que a combinação dessas intervenções no tratamento do controle postural é uma boa opção para fisioterapeutas.

Discontinuation of Health Interventions Among Brazilian Older Adults During the Covid-19 Pandemic: REMOBILIZE Study

The objective of this study was to analyze changes in access to health interventions during the pandemic among Brazilian older adults and to investigate the factors associated with social and health inequalities. We conducted an online survey with Brazilian adults aged 60  +  years between May and June 2020. A multidimensional questionnaire was used to investigate access to health interventions during the pandemic and associated factors. Of 1482 participants, 56.5% reported health care before the pandemic, and 36.4% discontinued it during the pandemic. The discontinuation rate was 64.4% (95% CI 61.1-67.6). Participants with higher educational level (nine or more years of education: OR 0.34; 95% CI 0.17-0.70) and higher income (eight or more times the minimum wage: OR 0.54; 95% CI 0.36-0.81) were associated with less probability of discontinuation. Presenting multimorbidity (OR: 1.42; 95% CI 1.06-1.90) and polypharmacy (OR: 0.61; 95% CI 0.46-0.81) were associated with discontinuity in health interventions. Our study showed that structural health inequities in access to health care shaped the rates of discontinuation in health care interventions during the COVID-19 pandemic. Strategic actions should be set up to actively monitor socially vulnerable older adults and strengthen community-based services to mitigate the discontinuation of health care interventions.

Health-Related Quality of Life and Associated Factors: Regional Differences Among Oldest-Old in Brazil

PURPOSE

The aim of this research was to investigate the extent to which socioeconomic and regional differences in Brazil may influence the quality of life. To this end, we examined factors associated with health-related quality of life in two populations of oldest-old people, aged 80 and over: one from the Northeast of Brazil and the other from the Southeast.

METHODS

417 participants aged 80 and over were interviewed face-to-face, 179 from Brejo dos Santos, one of the poorest regions in the Northeast; and 238 from São Paulo, one of the largest urban metropolises in Southeast Brazil. Data, which included socioeconomic and demographic factors, health status, and health-related quality of life, were collected using a structured questionnaire. The dependent variable was determined by the completion rate of the 12-item Short Form Survey and analyzed using multiple logistic regression.

RESULTS

Although the population of São Paulo had four times as many long-lived women than men, had better literacy levels, used more medications, and presented a greater prevalence of symptoms suggestive of depression in comparison to the Northeast's population, no difference was observed in the proportion of good physical components among the two populations, 54.3% in Brejo dos Santos' oldest-old and 50.4% in São Paulo's (P = .6272). Quality and quantity of sleep were factors that most affected the health-related quality of life among the oldest-old of Northeast.

CONCLUSION

Factors associated with health-related quality of life were different among the oldest-old people of the two locations, thereby corroborating the heterogeneous nature of the longevous population.

Multimorbidity and use of health services in the oldest old in Brazil

OBJECTIVE

To estimate the prevalence of multimorbidity in long-lived Brazilian individuals (age ≥80 years) and to associated it with the use of health services.

METHODS

Cross-sectional population-based study with data from the 2019 National Survey of Health (n=6,098). Frequencies of use of services were estimated for older people with multimorbidity and according to sex, health insurance ownership, and self-rated health. The prevalence rates, crude and adjusted prevalence ratios, and the respective 95% confidence intervals were calculated.

RESULTS

The average age of the older adults was 85 years and about 62% were women; the prevalence of multimorbidity was 57.1%, higher in women, in those who have health insurance, and who reside in the southern region of the country (p<0.05). In the oldest old with multimorbidity, the use of services in the last 15 days reached 64.6%, and more than 70% were hospitalized in the last year or did not carry out activities in the previous two weeks for health reasons. Differences were observed for the indicators of service use in relation to sex, health insurance ownership, and self-rated health, according to multimorbidity.

CONCLUSION

Indicators for the use of health services were higher in older individuals who have two or more chronic diseases, regardless of sociodemographic conditions and self-rated health, showing the impact of multimorbidity per se in determining the use of services among the oldest old.

Polypharmacy Management in the Older Adults: A Scoping Review of Available Interventions

Background: Polypharmacy paves the way for non-adherence, adverse drug reactions, negative health outcomes, increased use of healthcare services and rising costs. Since it is most prevalent in the older adults, there is an urgent need for introducing effective strategies to prevent and manage the problem in this age group. Purpose: To perform a scoping review critically analysing the available literature referring to the issue of polypharmacy management in the older adults and provide narrative summary. Data sources: Articles published between January 2010-March 2018 indexed in CINHAL, EMBASE and PubMed addressing polypharmacy management in the older adults. Results: Our search identified 49 papers. Among the identified interventions, the most often recommended ones involved various types of drug reviews based on either implicit or explicit criteria. Implicit criteria-based approaches are used infrequently due to their subjectivity, and limited implementability. Most of the publications advocate the use of explicit criteria, such as e.g. STOPP/START, Beers and Medication Appropriateness Index (MAI). However, their applicability is also limited due to long lists of potentially inappropriate medications covered. To overcome this obstacle, such instruments are often embedded in computerised clinical decision support systems. Conclusion: Multiple approaches towards polypharmacy management are advised in current literature. They vary in terms of their complexity, applicability and usability, and no "gold standard" is identifiable. For practical reasons, explicit criteria-based drug reviews seem to be advisable. Having in mind that in general, polypharmacy management in the older adults is underused, both individual stakeholders, as well as policymakers should strengthen their efforts to promote these activities more strongly.

Use and access to medications for type 2 diabetes mellitus in elderly: a population-based household survey

The objective of this study was to analyze the use and access to medications for type 2 diabetes among older people registered in the family health strategy in Ribeirão Preto, São Paulo. A population-based household survey was undertaken with 338 older adults selected using two-stage cluster sampling. Pharmacotherapy of diabetes and access to medications was investigated using a structured questionnaire administered by means of face-to-face interviews. The number of medicines used to treat diabetes ranged between 1 and 4. Respondents predominantly used only oral antidiabetic agents. The use of metformin and sulfonylureas on their own was reported by 37.9% and 9.8% of respondents, respectively. Frequency of insulin use was greatest in the 80 years and overage group (38.9%). The large majority of respondents (96.4%) had full access to medicines. Means of payment was "free of charge" in 78.1% of the respondents and public pharmacies were the main source of medication (74.8%). The most commonly used oral antidiabetic was metformin, which is consistent with current treatment guidelines. However, the findings show inappropriate medication use among older people, more specifically the use of sulfonylureas on their own. The findings of this study highlight the important role played by the public health service in providing medications for type 2 diabetes.

Chronic polypharmacy at all age: A population-based drug utilization study

Polypharmacy is a growing concern often described only in older people by cumulating all drugs taken. We aimed to describe chronic polypharmacy in France, regardless of age. A cross-sectional descriptive study was performed using the 1/97th representative sample of the French health insurance nationwide database (EGB). All subjects alive on January 1, 2015, and covered by the French healthcare insurance were included, and their information collected until December 31, 2015, or date of death. Drug exposures were estimated from drug dispensing dates and treatment durations. Chronic uses of drug were defined as drugs used daily for more than 6 months. Chronic polypharmacy corresponded to the exposure to five chronic uses of drug or more. In 2015, information of 584 862 subjects was collected (mean age: 42.2 years). Prevalence of chronic polypharmacy was 5.6% and incidence 1.1%. Prevalence of chronic polypharmacy increased noticeably from 0.2% for subjects aged 18 to 40 years to a maximum of 29.2% for subjects aged 80 to 90 years and then decreased to 23.6% for subjects aged 90 years and more. Lipid-modifying agents were the most frequent drugs involved in chronic polypharmacy (10% of exposure). According to age, the most important differences between the younger and older people were found for cardiovascular drugs (43.5% vs. 45.7% of exposure, respectively) and nervous system drugs (13.7% vs. 11.5% of exposure, respectively). This population-based study showed increasing of chronic polypharmacy and evolution of chronic drug patterns with age.

Suicide in the elderly: an epidemiologic study

OBJECTIVE

To analyze the incidence and means of elderly suicide in Brazil.

METHOD

Epidemiologic, cross-sectional, quantitative, and retrospective study. The data were obtained in a platform maintained by the Ministry of Health and analyzed. The mortality rate was calculated and means and percentages regarding the employed means of suicide were obtained.

RESULTS

In this period, 8,977 suicides took place among the population over 60 years. The highest suicide rates were concentrated in the population over 80, which presented a mean 8.4/100,000 for this period, and between 70 and 79 years, with a mean rate of 8.2/100,000. Considering the total elderly population over 60 years, this value reached 7.8/100,000, whereas in the general population this was 5.3/100,000. The values are always higher among the elderly population: the mean rate in the last five years among the elderly is 47.2% higher than the mean for the general population. The main mean of suicide was hanging (68%), followed by firearm (11%), self-intoxication (9%), falling from a high place (5%), and undefined or undetermined means (6%).

CONCLUSION

Epidemiologic analyses bring visibility to the dyad aging and suicide, corroborating the pertinence of this theme.

Errors linked to medication management in nursing homes: an interview study

Background

The number of errors in medication management in nursing homes is increasing, which may lead to potentially life-threatening harm. Few studies on this subject are found in the municipal nursing home setting, and causes need to be identified. The aim of this study was to explore perceptions of errors connected to medication management in nursing homes by exploring the perspective of first-line registered nurses, registered nurses, and non-licensed staff involved in the care of older persons.

Methods

A qualitative research approach was applied based on semi-structured interviews with 21 participants at their workplaces: Seven in each of the occupational categories of first-line registered nurses, registered nurses, and non-licensed staff. Subcategories were derived from transcribed interviews by content analysis and categorized according to the Man, Technology, and Organization concept of error causation, which is as a framework to identify errors.

Results

Mistakes in medication management were commonly perceived as a result of human shortcomings and deficiencies in working conditions such as the lack of safe tools to facilitate and secure medication management. The delegation of drug administration to non-licensed staff, the abandonment of routines, carelessness, a lack of knowledge, inadequate verbal communication between colleagues, and a lack of understanding of the difficulties involved in handling the drugs were all considered as risk areas for errors. Organizational hazards were related to the ability to control the delegation, the standard of education, and safety awareness among staff members. Safety issues relating to technology involved devices for handling prescription cards and when staff were not included in the development process of new technological aids. A lack of staff and the lack of time to act safely in the care of the elderly were also perceived as safety hazards, particularly with the non-licensed staff working in nursing homes.

Conclusions

The staff working in nursing homes perceive that the risks due to medication management are mainly caused by human limitations or technical deficiencies. Organizational factors, such as working conditions, can often facilitate the occurrence of malpractice. To minimize mistakes, care managers need to have a systemwide perspective on safety issues, where organizational issues are essential.

Prevalence and Age Structure of Polypharmacy in Poland: Results of the Analysis of the National Real-World Database of 38 Million Citizens

Introduction: Polypharmacy is a risk factor for adverse health outcomes, higher use of medical services and additional costs. The problem has gained attention as a consequence of aging and related multimorbidity. Therefore, there is an urgent need to adopt effective interventions aimed at reducing its burden. In order to achieve this, in-depth understanding of the prevalence of polypharmacy is required. Of particular interest is, however, assessing prevalence of polypharmacy in various age groups, to reach the right target for these interventions. So far, only limited data on polypharmacy among non-elderly individuals have been available.

Aim of study: To assess overall prevalence of polypharmacy in Poland as well as its distribution in various age groups using real-world data.

Methodology: A retrospective analysis of complete dispensation data of national payer organization for the years 2018–2019. The analyzed dataset included data on dispensation of reimbursed drugs, and exclusively for 2019, also non-reimbursed drugs. Polypharmacy was defined as dispensation of ≥5 prescription medications within six months.

Results: In the analyzed national cohort of 38 million Polish citizens, the prevalence of polypharmacy was found to be 11.7% in 2018 and 11.6% in 2019. With age, the prevalence of polypharmacy increased, reaching the value of 56.0% in those aged 80+ in 2018, and 55.0% in 2019. Altogether, among those aged 65+, the polypharmacy was present in 43.1% in 2018, and 42.1% in 2019. In the youngest group of citizens, i.e., among those aged below 20 years, polypharmacy was found in 0.9%, and 0.8% in 2018 and 2019, respectively. Prevalence of polypharmacy, calculated for 2019 according to dispensation of five or more reimbursed and non-reimbursed drugs for the whole Polish population, was 21.8% for January-June, and 22.4% for July-December 2019. Among those aged 65+, the relevant numbers were 62.3%, and 62.9%, respectively.

Conclusion: This study, being the first nationwide assessment of polypharmacy in Poland, confirmed its high prevalence. We found polypharmacy present in over one fifth of Polish society. Peaking in the elderly, polypharmacy occurred in each age group. These results lay the foundations for future interventions focused on reducing the scope of this problem in Poland.

Inappropriate Prescribing of Proton Pump Inhibitors in Outpatient Clinics

Proton pump inhibitors are the commonly prescribed drugs for acid-related disorders. However, many of those prescriptions are inappropriate in inpatient and outpatient settings according to the recommended guidelines. Many studies have been conducted in inpatient clinics, but data about the appropriateness of proton pump inhibitor prescribing in outpatient clinics are scarce. Therefore, the aim of this study was to determine inappropriate proton pump inhibitor prescribing rates among patients admitted to a tertiary hospital family medicine outpatient clinic. A total of 259 patients (median age = 59 years; 72.6% women) were enrolled into the study and 35.9% of them had no proper indications to utilize proton pump inhibitors. Inappropriate proton pump inhibitor usage rate was significantly higher in patients older than 60 years compared with their younger counterparts (62.4% vs. 37.6%; p = .001). The most frequent reason to use a proton pump inhibitor with nonapproved indications was polypharmacy (41.9%). Despite endoscopic evaluation, 41.9% of the patients received a proton pump inhibitor without an approved indication. A significant proportion of nonindicated prescriptions were a consequence of continued prescribing without re-evaluating patients in outpatient clinics. Consideration of proton pump inhibitor indications according to the guidelines in every admission may prevent inappropriate prescriptions.

Anti-Cholinergic Drug Burden Among Ambulatory Elderly Patients in a Nigerian Tertiary Healthcare Facility

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

Relationship between neighborhood food environment and diet variety in Japanese rural community-dwelling elderly: a cross-sectional study

Background

Food access is an important aspect of health promotion for the elderly. The aim of this study was to investigate the relationship between distance to the nearest food store and diet variety in rural community-dwelling elderly Japanese.

Methods

This cross-sectional study analyzed data from 1,103 elderly participants surveyed by mail in rural areas of Japan. Diversity of food intake was assessed using the diet variety score (DVS). Street network distance from home to food store was calculated and categorized by quartile using a geographic information system and analyzed in relation to diet using multivariable regression with the primary outcome as low DVS. Sub-analysis of the association with DVS was conducted for each food store category (convenience store, supermarket, and small food store). The association between intake frequency of each food group and distance was also analyzed.

Results

Participants in the fourth quartile of distance to food store had significantly higher prevalence ratio (1.15; 95% CI, 1.01–1.32) for low DVS than those in the first quartile. There was a significant tendency between greater distance to food store and lower DVS (P for trend = 0.033). Supermarkets and convenience stores, in particular, showed significant associations. Greater distance was significantly associated with lower frequency of meat and fruit intake.

Conclusion

There was significant association between distance to nearest food store and diet variety in rural Japanese elderly. These findings suggest the importance of interventions for areas at high risk of low diet variety, such as places far away from food stores.

Prevalência e fatores associados à polifarmácia em pessoas idosas de uma área rural

Resumo Objetivo Avaliar a prevalência e fatores associados à polifarmácia em pessoas idosas de uma área rural. Método Estudo transversal, quantitativo, realizado com pessoas idosas residentes de uma área rural no município de Ponta Grossa, Paraná, Brasil (n=80). Para a coleta de dados utilizou-se um questionário estruturado. Considerou-se como variável dependente a polifarmácia e, como variáveis independentes as características sociodemográficas, de estilo de vida, presença de doenças crônicas, autopercepção em saúde, quedas no último ano, sugestivo de comprometimento cognitivo e nível de fragilidade. Realizou-se teste de qui-quadrado e regressão logística. Resultados A prevalência de polifarmácia foi de 40,0%. A maioria era do sexo feminino (52,5%), com idade entre 60 e 74 anos (61,2%), cor branca (76,2%), casados (62,5%), e ensino fundamental incompleto (66,2%). A polifarmácia esteve associada ao nível de fragilidade (OR=3,73;IC95%=1,09-12,74; p=0,036), indicativo para sarcopenia (OR=5,02; IC95%=1,39-18,13; p=0,014) e diabetes (OR=9,20; IC95%=2,37-36,05; p=0,001). Conclusão Verificou-se alta prevalência de polifarmácia nas pessoas idosas residentes na zona rural, sendo essa condição atrelada a fatores inerentes ao maior grau de fragilidade, indicativo de sarcopenia e diabetes.

Breast cancer, placing drug interactions in the spotlight: is polypharmacy the cause of everything?

PURPOSE

Breast cancer is the most prevalent and lethal cancer among women. Forty-one percent of cases occur in people ≥ 70 years, hindering their treatment given its comorbidities and polypharmacy (PP). Potential drug-drug interactions (PDDI) were analyzed in elderly breast cancer patients between daily and oncospecific treatments and their associations with Age, BMI, Mini Nutritional Assessment (MNA), Frailty categorization, PP, and adverse effects.

PATIENTS/METHODS

A cohort of 77 patients ≥ 70 years with breast cancer who underwent a Comprehensive Geriatric Assessment (CGA) were included. Clinical characteristics were collected using medical records. PDDI between treatments were analyzed using two databases. Data were assessed using linear regression, Chi-square, Mann-Whitney U, and Kruskal-Wallis tests. Finally, a multivariate logistic regression model was built and tested to predict adverse effects.

RESULTS

From 719 PDDI, 530 (74%) were moderate (r2 = 0.72) and the median number of drugs during oncospecific treatment (r2 = 0.73) was 9 (range 3-26). Overall, 59 patients (77%) had adverse effects associated with Frailty categorization and MNA (p < 0.05). The distribution of major, moderate, minor, and total PDDI was associated with PP at CGA and during oncospecific treatment (p < 0.05). Moreover, it was verified that Frailty categorization protects from adverse effects given the intervention made at CGA.

CONCLUSIONS

CGA should be applied in oncologic elderly patients to assess clinical outcomes and categorize them according to their frailty but also to analyze PDDI. Furthermore, we encourage the use of the model in clinical practice for predicting the occurrence of adverse effects, improving therapeutic conciliation.

Prevalência e fatores associados à utilização de medicamentos potencialmente inapropriados para pessoas idosas em Rio Branco, Acre, Brasil: um estudo de base populacional

Resumo Objetivo Verificar a prevalência e analisar os fatores associados ao uso de medicamentos potencialmente inapropriados (MPI) em pessoas idosas de Rio Branco, Acre, Brasil. Método Trata-se de um estudo transversal de base populacional. A variável dependente foi uso de pelo menos um MPI, de acordo com os critérios do Consenso Brasileiro de Medicamentos Potencialmente Inapropriados para Idosos (CBMPII), independentemente da condição clínica. Na avaliação da associação entre o uso de medicamentos inapropriados e as variáveis independentes, realizou-se análise bruta e ajustada por meio de regressão logística, utilizando-se o modelo hierarquizado por razão de chances (OR). Resultados A prevalência de uso de pelo menos um MPI entre os 1.016 participantes foi de 25,9% (IC95% 22,3; 29,8), associada positivamente a sexo feminino (OR=1,38; IC95% 1,01; 1,90), dependência quanto às atividades instrumentais da vida diária (OR=1,37; IC95% 1,02; 1,83), autoavaliação de saúde negativa (OR=1,54; IC95% 1,12; 2,11), internação nos últimos 12 meses (OR=1,79; IC95% 1,19; 2,69) e presença de mais de três comorbidades (OR= 2,56; IC95% 1,97; 3,33). A subcategoria mais utilizada foi dos inibidores de bombas de prótons, por 11,3% (9,2; 13,8). Conclusão A prevalência de uso de MPI por idosos da amostra foi de um quarto, estando associada ao sexo feminino e a condições de saúde. Ações de conscientização fazem-se necessárias para garantia dos benefícios no uso dos medicamentos.

Potentially inappropriate medication use in older adults: prevalence and physician knowledge

OBJECTIVE: To analyze the frequency, profile, and additional variables associated with the prescription of potentially inappropriate medications (PIM) to older adults in primary care, and evaluate physicians’ knowledge about these medications. METHODS: A cross-sectional study was conducted based on data from patient records for the period of January 2014 to December 2017 in a city located in the state of Minas Gerais. The frequency of PIM use was evaluated based on the 2019 Beers-Fick criteria. Physician knowledge was evaluated using a validated questionnaire as a primary data source. RESULTS: In a sample of 423 older adults, 75.89% (n = 321) used at least one PIM, the most common of which were medications used to treat central nervous system disorders (48.00%; n = 203). Most participants were female (62.41%; n = 264) and 70 years or older (69.50%; n = 294). When presented with clinical cases illustrating common situations in the management of older patients, 53.33% of physicians (n = 8) answered four or five questions correctly out of a possible seven; 13.33% (n = 2) answered six questions correctly; and 33.33% (n = 5) obtained three correct answers or fewer. CONCLUSIONS: These findings showed a high frequency of PIM use among older adults treated in Primary Health Care settings, with medications used in the treatment of central nervous system disorders. Our results highlight the importance of continuing education for health professionals and improved assessments of the medication available in the Unified Health System (Sistema Único de Saúde; SUS) for use in older adults, especially those taking multiple medications

Categorisation of Pharmaceutical Adverse Events Using the Japanese Adverse Drug Event Report Database: Characteristic Adverse Drug Events of the Elderly Treated with Polypharmacy

Background

Pharmacokinetics and pharmacodynamics of drugs in elderly individuals differ from those in younger adults; thus, adverse drug events (ADEs) are common in older patients with polypharmacy because co-existing comorbidities elevate the risk of ADEs occurring. However, ADEs have not yet been characterised based on the elderly patients of Japanese origin and polypharmacy.

Objective

The 100 most commonly reported ADEs were grouped into four classes (Class 1–Class 4) based on elderly patients with polypharmacy.

Patients and Methods

In this study, logistic regression analysis was performed using cases recorded in the Japanese Adverse Drug Event Report (JADER) database.

Results

ADEs in elderly patients treated with polypharmacy—in whom the risk of electrolyte abnormalities, renal and respiratory disorders, and coagulopathy was high—were categorised as ‘Class 1 [E(+), P(+)]’, while ADEs in elderly patients not treated with polypharmacy—in whom the risk of delirium and fall was high—were categorised as ‘Class 2 [E(+), P(−)]’. When there was no association with being elderly, ADEs associated with polypharmacy that carried a high risk of myelosuppression and infection were categorised as ‘Class 3 [E(−), P(+)]’, and allergic ADEs that were not affected by being elderly or polypharmacy, were categorised as ‘Class 4 [E(−), P(−)]’. Class 1 events as well as Class 3 ADEs occurred more frequently in females than in males, whereas Class 3 ADEs (deep vein thrombosis and pulmonary embolism) occurred more frequently in males.

Conclusions

Class 1 and Class 2 ADEs should be investigated in analyses that focus on individual drugs.

Potentially inappropriate medications for the elderly: Incidence and impact on mortality in a cohort ten-year follow-up

INTRODUCTION

Pharmacological therapy plays an important role in disease control in the elderly; unfortunately, this comes with a high prevalence in the use of medications classified as potentially inappropriate.

OBJECTIVE

To analyze the incidence, risk factors, and survival of elderly people using potentially inappropriate medications (PIM).

METHOD

A ten-year follow-up assessment of elderly participants residing in a capital of Central Brazil was conducted. The initial assessment (baseline) included 418 elderly people. Data were collected through home interviews guided by a questionnaire covering socioeconomic, demographic, living conditions, and health variables. The medication information obtained comprised active ingredient, dosage, route, and regimen for the medications. The PIMs were classified according to 2019 Beers Criteria. The analyses were performed using STATA 15.0. For survival analysis, a Cox Regression was performed with the respective Kaplan Meier curve.

RESULTS

The incidence of PIM was 44.1 cases (95% CI: 35.2-54.7) per 1,000 people a year. The most used PIMs were nifedipine, glibenclamide, and sodium diclofenac. The risk factors were polypharmacy (aRR: 3.00; 95% CI: 1.31-6.88) and diabetes mellitus (aRR: 1.57; 95% CI: 1.03-2.39). We identified no statistically significant association between survival and the use of PIM.

CONCLUSION

The study highlights the high consumption of PIM among the elderly causing polypharmacy risks. Health professionals working in drug treatment need to be alert to polypharmacy risks to ensure the rational use of medications to prevent adverse reactions and other health problems.

Polimedicação em adultos e idosos cadastrados na Estratégia Saúde da Família

Introdução: Verifica-se, no contexto global, a modificação do perfil da morbimortalidade em decorrência das transições demográfica e epidemiológica, relacionadas ao aumento do número de idosos e de doenças crônicas não-transmissíveis. Nesse cenário, a polimedicação tem se tornado frequente e, por conseguinte, seus danos são visualizados. O uso de múltiplos medicamentos amplia o risco de prescrições potencialmente inapropriadas, o que propicia interações farmacológicas, eventos adversos a medicamentos e hospitalizações. Soma-se a isso o ônus ao sistema de saúde e à assistência médica. Objetivo: Identificar os fatores associados à polimedicação em adultos mais velhos e idosos. Métodos: Trata-se de um estudo transversal e quantitativo, realizado em 2018 e 2019, com n=147 adultos (45-59 anos) e n=153 idosos (≥60 anos), cadastrados na Estratégia Saúde da Família (ESF) no município de Três Lagoas/MS. Foram coletados dados de caracterização sociodemográfica, estilo de vida, rede de apoio social e informações sobre saúde. Questionou-se o número de fármacos de uso contínuo tomados por dia, sendo considerada polifarmácia a utilização de cinco ou mais medicamentos. Foi conduzida uma regressão logística binomial para identificar os fatores associados à polifarmácia. Resultados: A prevalência de polifarmácia foi 10,2% (IC95% = [6,3%-16,2%]) para os adultos e 17,0% (IC95% = [11,9%-23,7%]) para os idosos. Estiveram associados à polifarmácia para o grupo de adultos o aumento da idade (OR=1,32; IC95%=1,10-1,59) e não possuir companheiro (OR=6,52; IC95%=1,59-26,81). Já para o grupo de idosos, os fatores associados foram ter sofrido pelo menos uma queda no último ano (OR=3,33; IC95%=1,13-9,85), ser tabagista (OR=5,04; IC95%=1,30-19,62), avaliar a saúde como regular (OR=4,10; IC95%=1,16-14,54) ou ruim/muito ruim (OR=6,59; IC95%=1,31-33,08). O consumo de álcool foi inversamente associado à polifarmácia (OR=0,15; IC95%=0,02-0,98) nos idosos. Conclusões: Diante dos potenciais riscos oferecidos pela polimedicação, torna-se imprescindível a distinção dos grupos em condição de maior vulnerabilidade ao uso de múltiplos medicamentos e um acompanhamento mais cauteloso, a fim de assegurar maior segurança na prescrição de fármacos na atenção primária e o aprimoramento do cuidado.

Uso de Práticas Integrativas e Complementares por idosos: Pesquisa Nacional de Saúde 2013

RESUMO O estudo teve por objetivo estimar a prevalência da realização de Práticas Integrativas e Complementares (PIC) e sua relação com doenças crônicas em idosos brasileiros. Estudo transversal de base populacional realizado com dados da Pesquisa Nacional de Saúde (PNS/2013; n=23.815). Estimaram-se a prevalência de realização de PIC e as frequências relativas das práticas referidas. Realizaram-se comparações entre proporções pelo teste de Rao-Scott com nível de significância de 5% e estimaram-se razões de prevalência para o uso das práticas integrativas e complementares, segundo doenças crônicas. O uso das PIC foi referido por 5,4% (IC95%:4,9-6,0) dos idosos. Entre estes, 62,6% relataram uso de plantas medicinais/fitoterapia; 22,2%, acupuntura; e 11,2%, homeopatia. Somente 6,7% realizaram o tratamento no SUS. Observou-se maior realização das práticas pelas mulheres e para todos os tratamentos considerados (p<0,001); naqueles com colesterol alto, artrite ou reumatismo, problema de coluna e depressão (p<0,05). Os resultados dimensionam o uso das PIC com dados de abrangência nacional, apontando para sua utilização no tratamento das diversas condições de saúde que acometem principalmente os idosos.

Avaliação farmacológica de medicamentos usados por idosos frequentadores de uma drogaria privada

Objetivo: realizar a avaliação da farmacoterapia de idosos frequentadores de uma drogaria privada.Método: a pesquisa abrangeu um estudo transversal realizado no período de junho a setembro de 2019, em uma drogaria privada, conveniada ao Programa Farmácia Popular do Brasil, localizada no município de Nova Bréscia/RS. Para a coleta de dados foi aplicado um questionário, a fim de analisar a farmacoterapia e os hábitos de vida dos idosos participantes da pesquisa na drogaria selecionada.Resultados: a população pesquisada envolveu 81 idosos, sendo a maioria composta por mulheres (69,1%) e a idade média dos participantes foi de 69,4 anos, predominando aqueles na faixa de 60 a 69 anos (53,1%). A grande maioria dos entrevistados (66,7%) se automedica; 36 (44,4%) pessoas foram classificadas com o nível de polifarmácia maior e uma média de 4,64 medicamentos por pessoas. No total, foram 45 pessoas (55,6%) que tiveram algum tipo de interação medicamentosa, variando uma média de 2,72 interações por pessoa. Na pesquisa, foram encontrados 59 medicamentos que são considerados inapropriados para os idosos de acordo com os Critérios de Beers.Conclusão: o envelhecimento predispõe os idosos a um aumento do uso de medicamentos, aumentando o nível de polifarmácia e as chances de ter interações medicamentosas. Assim, destaca-se a importância do profissional farmacêutico em orientá-los sobre os medicamentos, sobre a não utilização de alguns fármacos, o uso de doses adequadas, acompanhamento da terapia farmacológica, como a sua eficácia e, dessa forma, contribuir para uma qualidade de vida melhor.

Prevalence of polypharmacy and the association with non-communicable diseases in Qatari elderly patients attending primary healthcare centers: A cross-sectional study

BACKGROUND

Polypharmacy has become a global public health concern particularly in the elderly population. The elderly population is the most susceptible to the negative effects of polypharmacy due to their altered pharmacokinetics and decreased drug clearance. Therefore, polypharmacy can lead to poor health status and higher rates of morbidity and mortality.

OBJECTIVE

The objective of this study was to determine the prevalence of polypharmacy (≥ 5 drugs) and its association with non-communicable diseases (NCDs) in elderly (≥65 years) Qatari patients attending Primary Healthcare (PHC) centers in Qatar.

METHODS

A retrospective cross-sectional analysis was conducted using the Electronic Medical Record (EMR) database of all PHC centers in Qatar for six months (April-September 2017).

RESULTS

Out of 5639 patients screened, 75.5% (95% CI: 74.3-76.6) were exposed to polypharmacy. Females were 1.18 times more likely to have polypharmacy compared to males (95% CI: 1.03-1.34). The multivariate analysis identified having hypertension (AOR 1.71; 95% CI: 1.38-2.13), diabetes (AOR 2.38; 95% CI: 1.97-2.87), dyslipidemia (AOR 1.29; 95% CI: 1.06-1.56), cardiovascular disease (AOR 1.56; 95% CI: 1.25-1.95) and asthma (AOR 1.39; 95% CI: 1.13-1.72) to be independent parameters associated with polypharmacy. Also, the Body Mass Index (BMI) and number of NCDs were found to be significant independent parameters associated with polypharmacy.

CONCLUSIONS

The prevalence of polypharmacy among Qatari elderly attending PHC Centers is very high. Our findings confirm the strong relationship between polypharmacy and BMI, and certain NCDs. Healthcare professionals should be educated about the magnitude of polypharmacy, its negative effects, and its associated factors. Best practice guidelines should be developed for improved medical practice in the prescription of medications for such a vulnerable population.

Drug Safety in Geriatric Patients: Current Status and Proposed Way Forward

Elderly patients are the main users of drugs and they differ from younger patients. They are a heterogeneous population that cannot be defined only by age but should rather be stratified based on their frailty. The elderly have distinctive pharmacokinetic and pharmacodynamic characteristics, are frequently polymorbid, and are therefore treated with multiple drugs. They may experience adverse reactions that are difficult to recognize, since some of them present non-specific symptoms easily mistaken for geriatric conditions. Paradoxically, the elderly are underrepresented in clinical trials, especially the frail individuals whose pharmacological response and expected treatment outcome can be different from those of non-frail patients. This means that the benefit-risk balance of drugs used in frail elderly patients is frequently unknown. We present some proposals to overcome the barriers preventing the enrollment of frail elderly patients in clinical trials, and strategies for monitoring their therapy to minimize the risk of adverse reactions. Automated alerts for drug and drug-disease interactions could help appropriate prescribing but should flag only clinically relevant interactions. Pharmaceutical forms should be designed to allow easy dose adjustment and, together with packaging and labeling, should account for the physical and cognitive limitations of frail elderly patients. Aggregate pharmacovigilance reports should summarize the safety profile in the elderly, but rather than presenting the results by age they should focus on patients' frailty, perhaps using the number of comorbidities as a proxy when information on frailty is not available.

Autoavaliação negativa da saúde em pessoas idosas associada a condições socioeconômicas e de saúde: inquérito populacional em Rio Branco, Acre

Resumo Objetivo Estimar a prevalência de autoavaliação negativa da saúde e sua associação com condições socioeconômicas, sintomas depressivos, funcionalidade e morbidades autorreferidas em pessoas idosas de Rio Branco, Acre. Método Trata-se de uma pesquisa realizada com dados do Estudo das Doenças Crônicas em Idosos (EDOC-I), um inquérito domiciliar realizado com pessoas a partir de 60 anos residentes em Rio Branco, Acre, Brasil, em 2014 (n=1.016). A autoavaliação negativa da saúde foi definida pelos estratos “ruim” e “muito ruim”. Foram aplicadas as escalas de depressão geriátrica e das atividades da vida diária e instrumentais da vida diária. Como medida de associação da autoavaliação negativa da saúde com variáveis de interesse foi empregada a técnica de regressão logística múltipla. Resultados A prevalência de autoavaliação negativa da saúde foi de 15,4%, apresentando associação estatisticamente significativa com sexo feminino (OR:1,72; IC95%:1,17-2,51), baixa escolaridade (OR:2,33; IC95%:1,37-3,97), sedentarismo (OR:1,84; IC95%: 1,08-3,14) e uso de medicamentos (OR:3,01; IC95%:1,52-5,95). Também se detectou associação com sintomas depressivos (OR:2,55; IC95%:1,74-3,73), presença de multimorbidades (OR:1,73; IC95%:1,15-2,61) e dependência total nas atividades instrumentais da vida diária (OR:2,42; IC95%:1,40-4,17). As morbidades associadas à percepção negativa da saúde foram: asma/bronquite (OR:2,74; IC95%:1,61-4,67), insônia (OR:1,80; IC95%:1,25-2,58) e problemas cardíacos (OR:1,77; IC95%:1,18-2,68). Conclusão Assim, a autoavaliação negativa da saúde das pessoas idosas sofre influência das condições socioeconômicas e de saúde, sendo um indicador útil para o delineamento de estratégias em saúde que favoreçam o envelhecimento com independência e bem-estar físico e emocional.

Polypharmacy: A general review of definitions, descriptions and determinants

Polypharmacy is considered as the administration of many drugs. It is a major public health concern, which is growing worldwide. The identification of polypharmacy relies on drug count on a given time window. Polypharmacy exists if this count exceeds a predefined threshold. Although there is no consensus among scientists, five is the most frequently used number. Depending on the time-windows, polypharmacy can be qualified as simultaneous, cumulative, or continuous. Drugs can be selected according to the duration or the recurrence of their use thereby introducing the concept of chronic polypharmacy. This general review aimed to compile data from the literature regarding descriptions and determinants of polypharmacy, according to used definitions and studied populations. The prevalence of polypharmacy varied according to the definition used (from 4% to 57%). It was high in elderly people but was also non negligible in younger subjects such as middle aged. Cardiovascular, digestive and metabolism drugs were among the most frequent drugs involved in polypharmacy. The determinants of polypharmacy included factors linked to the patient (sociodemographic parameters such as age, sex, income, and place of residence, ethnicity, behaviour), factors linked to the disease (certain diseases such as cardiovascular or metabolic disease, multiple comorbidity status), as well as factors linked to the healthcare system or to the physician. Finally, to date, little data is available regarding polypharmacy appropriateness, although these data are needed to have clinically important information beyond a quantitative estimation. Further research is warranted to fill this gap.

High Levels of Polypharmacy in Rheumatoid Arthritis-A Challenge Not Covered by Current Management Recommendations: Data From a Large Real-Life Study

BACKGROUND

Rheumatoid arthritis (RA) is associated with high frequency of comorbidities and increased risk of polypharmacy. Although there is a great potential for complications, there is a gap in literature on polypharmacy in patients with rheumatic arthritis.

OBJECTIVE

To evaluate the prevalence and factors associated with polypharmacy in a population in a real-life setting.

METHODS

A cross-sectional multicenter study was conducted in Brazil. Patients underwent clinical evaluation and medical records analysis. Polypharmacy was considered as a dependent variable. To test independent variables, we used Poisson regression.

RESULTS

We evaluated 792 patients (89% female, median age 56.6 years). Median duration of disease was 12.7 years, 78.73% had a positive rheumatoid factor. The median of disease activity score-28 was 3.5 (disease with mild activity), median of the clinical disease activity index score was 9, and median of health assessment questionnaire-disability index was 0.875; 47% used corticosteroids, 9.1% used nonsteroidal anti-inflammatory drugs, 90.9% used synthetic disease-modifying antirheumatic drugs, 35.7% used biologic disease-modifying antirheumatic drugs (DMARDs). In total, 537 (67.9%) patients used 5 or more drugs. Polypharmacy showed a relationship with a number of comorbidities and use of specific drugs (corticosteroids, methotrexate, and biological DMARDs).

CONCLUSION

We found a high prevalence of polypharmacy (67.9%) in RA. Solutions to management this problem should be stimulated.

Factors associated with medication-related problems in an ambulatory medicare population and the case for medication therapy management

BACKGROUND

Medication-related problems (MRPs) are a major healthcare burden. The rate of MRPs in those ≥65 years old is ∼50 events per 1000 person-years, and contributes to a four-fold higher hospitalization rate when compared to younger patients. Medication therapy management (MTM) can identify MRPs in high-risk patients. However, in 2015, only 12.9% of Medicare patients qualified for MTM services through their Part D plan.

OBJECTIVE

To examine the type and frequency of MRPs in community-dwelling Medicare beneficiaries and which patient factors are associated with having ≥1 MRP.

METHODS

Fourteen health clinics targeting Medicare beneficiaries were held in 10 Northern/Central California cities during Fall 2017. Trained student pharmacists, supervised by licensed pharmacists, conducted comprehensive medication reviews. Sociodemographic, chronic condition, medication, and MRP data were collected via standardized surveys.

RESULTS

MTM services were provided to 910 patients, of which 633 (69.6%) had at least 1 MRP. The most common MRPs were severe drug-drug interaction [n = 297(33.4%)] and untreated condition [n = 134 (14.7%). Individuals with MRPs took significantly more prescription and over-the-counter medications. Additionally, those with MRPs were more likely to be subsidy recipients and in a Medicare Advantage Prescription Drug Plan. A total of 120 (13%) individuals were found to have had an MRP severe enough to warrant prescriber follow-up.

CONCLUSIONS

Although only a fraction of Medicare beneficiaries qualify for MTM services through their Part D plan, many can benefit from such services. Understanding the type, frequency, and factors contributing to MRPs is imperative to identify and avoid negative sequelae. Reduction of MRPs can potentially improve patient clinical outcomes, increase quality-of-life, and decrease overall cost of care.
