Medication-related quality of life among Ethiopian elderly patients with polypharmacy: A cross-sectional study in an Ethiopia university hospital

Selection of outcome measurement instruments for a core outcome set for trials aimed at improving appropriate polypharmacy in older people in primary care: a Delphi consensus study

BACKGROUND

Despite developing a polypharmacy core outcome set (COS) in primary care, it is not clear how these outcomes should be measured.

AIM

To select outcome measurement instruments (OMIs) for a COS targeting appropriate polypharmacy in older patients in primary care.

METHOD

Following the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guideline, OMIs were identified from a Cochrane review focusing on appropriate polypharmacy. The quality of OMIs was assessed using a published checklist. Subsequently, two rounds of Delphi questionnaires were conducted via the SoGoSurvey® platform, engaging stakeholders (researchers, clinicians and journal editors specialising in geriatric primary care) to achieve consensus on OMIs using a scale encompassing "agree", "disagree", or "unsure". Consensus was achieved if 70% or more participants chose "agree" and 15% or fewer chose "disagree."

RESULTS

The quality of 20 OMIs identified from the Cochrane review was evaluated. Seven OMIs were selected based on meeting the COSMIN guideline's minimum requirements. Out of 188 potential participants, 57 (30.3%) consented to participate. Rounds 1 and 2 of Delphi exercises were completed by 50 respondents, achieving agreement on three OMIs: 'number of serious adverse drug reactions (ADRs)' (98%), 'number of deaths' (76%), and 'number of patients who fell' (70%) for measuring 'serious ADRs,' 'mortality,' and 'falls,' respectively. No agreement was reached for 'medication appropriateness,' 'medication side-effects,' 'quality of life,' and 'medication regimen complexity.'

CONCLUSION

OMIs were selected for a limited number of outcomes in the polypharmacy COS. Future research should identify suitable OMIs for the remaining four outcomes.

Validation of Quality-of-Life assessment tool for Ethiopian old age people

Background

A valid and reliable quality of life (QOL) assessment tool is critical for identifying health issues, evaluating health interventions, and establishing the best health policies and care plans. One of the tools for this goal is the World Health Organization's Quality of Life Old module (WHOQOL-OLD). It is validated and available in more than 20 languages globally, except Amharic (the widely spoken language in Ethiopia). As a result, the purpose of this study was to translate it into Amharic language and validate it among the elderly people in Bahir Dar City, Northwestern Ethiopia.

Methods

This was a cross-sectional study conducted among 180 community-dwelling old age people in Bahir Dar City, Ethiopia, from January 16 to March 13, 2021. Psychometric validation was achieved through Cronbach's alpha of the internal consistency reliability test and construct validity from confirmatory factor analysis.

Results

The study participants were aged between 60 and 90 years, with a mean age of 69.44. Females made up 61.7% of the study population, and 40% of them could not read or write. The results showed a relatively low level of quality of life, with a total transformed score of 58.58±23.15. The Amharic version of the WHOQOL-OLD showed a Cronbach's Alpha value of 0.96 and corrected item-total correlations of more than 0.74. The confirmatory factor analysis confirmed the six-domain model with a chi-square (X2) of 341.98 and a p-value less than 0.001. The comparative fit index (CFI) was 0.98, Tucker-Lewis's index (TCL) was 0.97, and the root mean square error of approximation (RMSEA) was 0.046.

Conclusion

The Amharic version of the WHOQOL-OLD indicated good internal consistency reliability and construct validity. The tool can be utilized to provide care to Ethiopian community-dwelling old age people.

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

Background and Aims

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

Methods

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

Results

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

Conclusion

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

Knowledge, attitudes and beliefs toward polypharmacy among older people attending Family Medicine Clinic, Nairobi, Kenya

BACKGROUND

Life expectancy has increased over the last century among older people, particularly those aged over 60 years. Aging is associated with increased disability, multiple chronic conditions, and increased use of health services managed with polypharmacy. There are few studies on polypharmacy and aging in sub-Saharan Africa, and it is unclear what older people know and their attitudes toward polypharmacy. This paper presents findings from a study that aimed to understand older people's knowledge, attitudes and beliefs about polypharmacy.

METHODS

A qualitative study using in-depth interviews of 15 patients aged 60 years and older who were taking more than five medications per day. The study was conducted at the Family Medicine Clinic (FMC), Aga Khan University Hospital, Nairobi. Data were analyzed using NVivo 12 software.

RESULT

Majority of participants had a good understanding of their underlying health conditions, but they did not know the specific names of the medications they were taking. Participants had diverse attitudes toward polypharmacy, with both positive and negative perceptions. Although adverse side effects were reported, participants remained positive because they believed these medicines were beneficial. Religion, faith and living healthy lifestyles were perceived to contribute to their positive attitude toward polypharmacy. Stigma and the cost of medication were reported as barriers.

CONCLUSION

This study provides valuable insights into the complexities of polypharmacy in older people. It highlights the importance of patient education, fostering strong patient-provider relationships, de-stigmatization, and improving medication affordability and accessibility. Further research could explore the polypharmacy of older people attending public institutions in rural Kenya.

Prevalence of polypharmacy among older adults in Ethiopia: a systematic review and meta-analysis

Polypharmacy is a significant concern for older adults. Taking multiple medicines to prevent and treat comorbidities is very common in older adults, potentially leading to polypharmacy. Polypharmacy is associated with the development of geriatric syndromes, including cognitive impairment, delirium, falls, frailty, urinary incontinence, and weight loss. The prevalence of polypharmacy varies according to the literature. There is a paucity of data regarding the prevalence of polypharmacy among older adults. Therefore, this study aimed to estimate the pooled prevalence of polypharmacy among older adults in Ethiopia. A comprehensive search of databases, including PubMed, MEDLINE, EMBASE, Hinari, Cumulative Index to Nursing and Allied Health Literature, International Scientific Indexing, Cochrane library and Web of Science, and Google Scholar, was conducted. STATA statistical software (version 17) was used to analyze the data. Forest plot and I2 heterogeneity test were computed to examine the existence of heterogeneity. Subgroup analysis and sensitivity analysis were done to explore the source of heterogeneity. Publication bias was evaluated by using funnel plots and Egger's test. A random effect model was used to determine the pooled prevalence of polypharmacy. After reviewing 123 studies, 13 studies with a total of 3547 older adults fulfilled the inclusion criteria and were included in this meta-analysis. The result from 13 studies revealed that the pooled prevalence of polypharmacy among older adults in Ethiopia was 37.10% (95CI: 28.28-45.91). A Subgroup Meta-analysis showed that the heterogeneity level was slightly lower among studies done in Oromia region (I2 = 46.62, P-value = 0.154). Higher pooled polypharmacy prevalence was found among older adults with cardiovascular disorders (42.7%) and admitted patients (51.4%). In general, it was found that the pooled prevalence of polypharmacy among older adults in Ethiopia was high. More than one in three older adults take five or more medications at a time. Thus, intervention focusing on rational geriatric pharmacotherapy is significant to prevent unnecessary pill burden, adverse drug events, medical costs, geriatric morbidity, and mortality. Furthermore, enhancing pharmacist roles towards medication therapy management and safety monitoring in older adults is also indicated.

Prevalence of polypharmacy and medication-related quality of life among adult patients in Al-Ahsa, Saudi Arabia

Polypharmacy, often defined as the concurrent use of five or more medications, has become increasingly common due to various factors, including shifts in lifestyle and a rise in health-related issues among individuals. However, using multiple medications could bring more issues to the patient, as it is linked to poor health outcomes, including medication nonadherence, adverse pharmacological effects, and decreased quality of life (QoL). This study aimed to determine the prevalence of polypharmacy and identify drug-related problems among adult patients in Al-Ahsa. A cross-sectional study was conducted among adult patients living in Al-Ahsa, Saudi Arabia, taking five or more medications. A self-administered questionnaire was distributed among the target population using an online survey. The questionnaire included sociodemographic data (i.e., age, sex, education, etc.), a questionnaire to assess behaviors regarding the use of polypharmacy, and a 10-item questionnaire to measure medication-related quality of life (MRQoL). In total, 196 of the 1,088 patients surveyed took five or more medications, indicating an 18% prevalence of polypharmacy. Among the 196 patients, 26.5% reported poor medication-related QoL. In univariate analysis, sex, occupational status, average monthly income, hypertension, asthma, difficulty managing medications, and side effects experienced were significantly associated with MRQoL. Independent significant predictors of poor MRQoL were having asthma and difficulty managing medications. The prevalence of poor medication-related quality of life among adult patients in our region was 26.5%, lower than that in previous studies. Poor MRQoL was associated with lower monthly income, hypertension, asthma, side effects, and difficulty managing medications.

Health-related quality of life and its determinants among patients with diabetes mellitus: a multicentre cross-sectional study in Northwest Ethiopia

OBJECTIVES

This study assessed the health-related quality of life (HRQoL) and its determinants in patients with diabetes.

DESIGN AND SETTING

An institutional-based multicentre prospective cross-sectional study design was conducted in diabetes follow-up clinics of selected hospitals in Northwest Ethiopia from April to July 2022.

PARTICIPANTS

All eligible adult patients with diabetes at the selected facilities.

MAIN OUTCOME MEASURES

HRQoL was measured using EuroQol 5-dimensions 5-levels (EQ-5D-5L) and the EuroQol-Visual Analogue Scales (EQ-VAS) instruments. A lower EQ-5D-5L utility mean score for each dimension and/or an overall lower utility score of EQ-5D-5L and EQ-VAS scores are intended to show poor HRQoL. Linear regression analysis was used to identify the association of HRQoL and other variables.

RESULTS

Out of the 422 samples approached, 402 (95.3%) participated in the study. Most of the participants (>85%) reported having moderate-to-severe problems in all five EQ dimensions. The overall EQ-5D-5L utility and EQ-VAS scores were 0.56 (±0.11) and 56.7 (±10.1), respectively. A higher body mass index (BMI) (p < 0.001), a higher number of medications (p = 0.037), a high level of blood glucose (p < 0.001), the presence of comorbidities and/or complications (p = 0.031), hypoglycaemia (p = 0.043) and taking insulin (p < 0.001) were associated with worsened HRQoL, whereas practicing self-monitoring of blood glucose (p = 0.002) and taking aspirin (p = 0.008) had a significant association with increased HRQoL.

CONCLUSION

This study concluded that the HRQoL of patients was compromised in all five measuring dimensions. The EQ-5D-5L utility and EQ-VAS scores were far lower than other findings. Clinical and medication-related variables, such as a higher BMI, a higher number of medications, the presence of comorbidities and/or complications, hypoglycaemia and insulin use were associated with poor HRQoL in patients with diabetes. As a result, interventions should be individualised and focused on determinant factors.

Evaluation of quality of life in the elderly who have fallen

Background/Aim: Approximately 30% of older adults fall at least once per year; consequently, falls are a significant public health concern in the elderly. The most common outcomes are fractures, immobility, high morbidity, and mortality rates. In recent years, quality of life (QoL) is used as a criterion to guide social policies for the elderly. The high prevalence of falls can have serious consequences on the QoL of older people, resulting in prolonged hospitalization, institutionalization, need for care, social isolation, anxiety, and depression. Therefore, it is essential to understand the effect of falls on QoL and influencing factors. In light of this study’s results, it is intended to provide recommendations for social policy that will protect the elderly from falls and maintain their high QoL. This study aimed to determine the QoL and the factors affecting the elderly who have fallen. Methods: The research was a cross-sectional study. The study sample consisted of 90 elderly individuals who applied to the hospital due to falls. The inclusion criteria were being 65 years of age or older, applying to the hospital's emergency department, orthopedic or orthopedic surgery clinic due to a fall, not having passed 6 months from the date of discharge, and agreeing to participate in the study voluntarily. Data were collected through face-to-face interviews in January–June 2021 using the purposive sampling method. The Elderly Introduction Form was used to obtain sociodemographic data of the participants, as well as data on falls and their experiences after falls. The Quality of Life Scale for the Elderly was used to determine QoL. The student’s t-test was used to compare two categorical variables. ANOVA was used for more than two variables, and logistic regression analysis was also applied. Results: QoL levels were classified as poor, fair, and good, and 58.9% of the participants were found to have a fair QoL. In addition, according to the scale’s total score average of 3.17 (0.473), the general quality of life was found to be fair for all participants. According to the t-test and ANOVA results, the QoL was higher for those with higher education levels and those living with their spouses (P˂0.05). The QoL was low in those who had fractures, had surgery, were hospitalized for more than 4 days, and had chronic diseases (P˂0.05). In the regression analysis model, age, economic status, and the number of drugs used were effective on QoL. Conclusion: The quality of life was poor in the elderly who experienced fractures and were hospitalized. Balance-enhancing exercises in the elderly can prevent falls and associated complications. Low education level, chronic illness, and drug use reduced the quality of life. For education, literacy courses and lifelong learning programs can be applied to the elderly. For diseases, healthy aging policies can be implemented.

Elderly Population Has Higher Prevalence of Polypharmacy Associated with Poor Quality of Life and Low Compliance after Recovery from COVID-19

Background

Long term effects of COVID are not fully understood yet. The geriatric population has been badly affected. The impact of COVID-19 on the health-related quality of life after recovery and patient compliance is a matter of concern especially in the geriatric population where polypharmacy is often prevalent.

Aims and Objectives

This study intended to observe the occurrence of polypharmacy (PP) among COVID-19 recovered older patients with multimorbidity and explore its association with health-related quality of life and compliance in these patients.

Materials and Methods

Total 90 patients, above 60 years of age having two or more co-morbidities and recovered from COVID-19 infection were included in this cross-sectional study. Number of pills taken daily by each patient was noted, to determine the occurrence of PP. WHO-QOL-BREF was used to assess the effect of PP on health-related quality of life (HRQOL). Medication adherence was measured using a self-reported questionnaire.

Results

PP was found in 94.4% while hyper polypharmacy was found in 45.56% of patients. The overall mean score of HRQOL in patients with PP was 187.91 ± 32.98, indicating poor quality of life with PP (p value 0.0014) whereas the overall mean score of HRQOL in patients with hyper polypharmacy was 177.41 ± 26.11, showing poor quality of life with hyper polypharmacy (p value 0.0005). Increased number of pills corelated with poor quality of life (r =0.49). The medication adherence was found to be poor in patients who received mean number of pills 10.44 ± 2.62 whereas the adherence was good if the mean number of pills was 8.20 ± 2.63, (p value of 0.0001).

Conclusion

Polypharmacy is highly prevalent among COVID-19 recovered patients and is associated with poor quality of life as well as poor medication adherence.

Effect of therapeutic regimens and polypharmacy on health-related quality of life of people with multiple myeloma: a cross-sectional study in Belo Horizonte, Brazil

OBJECTIVE

Multiple myeloma (MM) is an incurable hematological cancer and its treatment is geared to promote better Health-Related Quality of Life (HRQoL). We aimed to assess HRQoL and compare scores between variables on therapeutic regimens and polypharmacy in MM patients.

METHODS

This cross-sectional study was performed from April/2019 to February/2020 in Belo Horizonte, Brazil. HRQoL scores were obtained by the QLQ-C30 and QLQ-MY20 instruments. Data were retrieved from interviews and medical records. Therapeutic regimens were grouped into thalidomide-containing regimens; bortezomib-containing regimens; bortezomib and thalidomide-containing regimens; other therapeutic regimens, and remission group. We performed univariate analyses by the Mann-Whitney method and adopted the Kruskal-Wallis test for multiple comparisons. Robust multiple linear regression was used to determine the association between independent variables and the HRQoL scores.

RESULTS

The sample included 225 participants and most patients (65.3%) were on active treatment and had worse scores concerning future perspective. Polypharmacy was associated with worse scores on all scales in the univariate analyses. We observed a difference in the global health and body image (p < .05) scales in the multiple comparisons with therapeutic regimens. The global health scale difference was found between groups with other regimens and the remission group (p < .05). The difference between the bortezomib and thalidomide-containing regimens and remission group was not statistically significant (p = .077) in the body image scale. The multiple linear regression maintained the association of polypharmacy with worse HRQoL scores.

CONCLUSION

We identified an independent association between HRQoL and polypharmacy in MM patients. However, there was no difference between the evaluated regimens, suggesting they are equivalent in Brazil about HRQoL.

Care of Older Persons in Eastern Africa: A Scoping Review of Ethical Issues

Introduction

The aging population is rapidly increasing globally, with 80% of the older population living in low- and middle-income countries. In Eastern African countries, there exists an incongruence between readiness-economically, structurally, politically, and culturally-to create a conducive environment for healthy aging, which implies public health as well as ethical concerns. The aim of this scoping review was to explore existing evidence addressing the various ethical issues in connection with elder care in the region of Eastern Africa.

Methods

We searched six databases (Africa-Wide Information, AgeLine, CINHAL, MEDLINE, APA PsycInfo, and SocINDEX) to identify peer-reviewed journal articles that could meet some eligibility criteria such as being a peer-reviewed journal article written in English, having been published in any year until July 2020, and focusing on ethical issues in the care of older people aged 60 years and older from Eastern Africa. We also searched for additional evidence in the references of included papers and web-based platforms. We included 24 journal articles and analyzed them using the inductive content analysis approach.

Results

The included articles represent seven (38.9%) of the 18 countries in the Eastern African region. The articles covered six ethical concerns: lack of government attention to older persons (n = 14, 58.3%), inaccessibility of health care services (n = 13, 54.2%), loneliness and isolation (n = 11, 45.8%), gender inequalities in old age (n = 9, 37.5%), mistreatment and victimization (n = 8, 33.3%), and medical errors (n = 2, 8.3%).

Conclusion

This scoping review summarized ethical issues arising in relation to providing care for older persons in the Eastern African context. In light of the rapid increase in the number of older persons in this region, it is critical for governments and responsible bodies to implement and accelerate efforts promptly to generate more evidence to inform programs and policies that improve the health and wellbeing of older persons. Further research is needed to inform global health efforts that aim at improving the lives of older persons, particularly in low- and middle-income countries.

Medication-related quality of life (MRQoL) in ambulatory older adults with multi-morbidity and polypharmacy

PURPOSE

To assess medication-related quality-of-life (MRQoL) in multi-morbid older adults with polypharmacy and correlations with medications, frailty and health-related QoL.

METHODS

With a cross sectional study of multi-morbid geriatric medicine outpatients, we assessed MRQoL (MRQol-LSv1), frailty status, potentially inappropriate medications, Medication Adherence Rating Scale (MARS), health-related-QoL (Short-Form 12, SF12) and medication burden (Living with Medicines Questionnaire, LMQv2).

RESULTS

One-in-four (n = 59) of 234 outpatient attendees met inclusion criteria. Almost half (n = 106, 45%) were excluded due to cognition (MMSE < 26). Included participants (n = 27, mean age 80.2 years) experienced a median of 11 (IQR 9-13.5) co-morbidities and were prescribed a median of 10 (IQR 8-12.25) medications. Overall, MRQoL-LS.v.1 scores were low, suggesting good medication-related quality of life (median MRQoL-LS.v.1 score of 14, IQR 14-22). Correlations between MRQoL, number of daily medications, co-morbidity burden, LMQv2 score, SF12 scores and number of PIMs were non-significant.

CONCLUSION

MRQoL-LSv.1 is unsuitable for most patients attending geriatric ambulatory services.

Polypharmacy and trajectories of health-related quality of life in older adults: an Australian cohort study

Background

Health-related quality of life (HRQoL) is an important outcome measure when considering medical treatment; however, the impact of polypharmacy on trajectories of HRQoL over time is unknown. This study aimed to investigate the association between polypharmacy status and trajectories of HRQoL in older adults.

Methods

A longitudinal cohort study of 2181 community-dwelling adults, 65 years and older, who participated in the 2013 to 2017 waves of the Household Income and Labour Dynamics in Australia (HILDA) Survey. Polypharmacy was defined as the regular use of ≥ 5 prescription medications. Polypharmacy status was categorised into no polypharmacy, in 2013 only (baseline only polypharmacy), in 2017 only (incident polypharmacy) or at both time points (persistent polypharmacy). HRQoL was assessed through the SF-36 questionnaire generating two summary scores: physical component summary (PCS) and mental component summary (MCS). Linear mixed-effects models stratified according to polypharmacy status and change in comorbidities were used to assess trajectories of HRQoL.

Results

Older adults with persistent polypharmacy had lowest scores for HRQoL measures from 2013 to 2017. After adjusting for all covariates, those with incident polypharmacy had the steepest annual decline in both the PCS and MCS: − 0.86 in PCS and − 0.76 in MCS for those with decreasing or stable comorbidities, and − 1.20 in PCS and − 0.75 in MCS for those with increasing comorbidities.

Conclusions

Polypharmacy was associated with poorer HRQoL, even after adjusting for confounders. Incident polypharmacy was found to be associated with a clinically important decline in HRQoL and this should be considered when prescribing additional medication to older adults.

Deprescribing practice in a resource-limited setting: Healthcare providers' insights

AIMS

Inappropriate polypharmacy poses risks of adverse drug events, high healthcare costs and mortality. Deprescribing could minimise inappropriate polypharmacy and the consequences thereof. The aim of this study was to evaluate healthcare providers' (HCPs') attitudes toward and experiences with deprescribing practice in Ethiopia.

METHODS

We conducted an institution-based cross-sectional survey among HCPs at the University of Gondar Comprehensive Specialized Hospital, Ethiopia. We used a validated questionnaire developed by Linsky et al. The tool included questions that explore medication characteristics, current patient clinical factors, predictions of future health states, patients' resources to manage their own health and education and experience. One-way ANOVA was used to test the association between sociodemographic variables and their perception of deprescribing decisions.

RESULTS

Of 85 HCPs approached, about 82 HCPs completed the survey, giving a response rate of 96.5%. Most of the participants (n = 73, 89%) have scored less than 1.5 points showing they are reluctant to proactively deprescribe. Physicians seem to be affected by the significant physical health conditions (mean = 1.68) and clinical endpoint like blood pressure (mean = 1.5) to make deprescribing decisions. According to the post hoc analysis of one-way ANOVA, clinical pharmacists seemed to have a better attitude toward deprescribing decisions compared with physicians (P = .025).

CONCLUSION

HCPs' decision to discontinue a medication could be multifactorial. Physicians could be influenced by physical health condition and clinical endpoints for deprescribing decision. Future studies should emphasise on barriers and facilitators to deprescribing practice specific to the context in Ethiopia.

Prevalence and Determinants of Multimorbidity, Polypharmacy, and Potentially Inappropriate Medication Use in the Older Outpatients: Findings from EuroAgeism H2020 ESR7 Project in Ethiopia

Few studies have been conducted on multimorbidity (two or more chronic diseases) and rational geriatric prescribing in Africa. This study examined the prevalence and determinants of multimorbidity, polypharmacy (five or more long-term medications), and potentially inappropriate medication (PIM) use according to the 2019 Beers criteria among the older adults attending chronic care clinics from a single institution in Ethiopia. A hospital-based cross-sectional study was conducted among 320 randomly selected older adults from 12 March 2020 to 30 August 2020. A multivariable logistic regression analysis was performed to identify the predictor variables. The prevalence of multimorbidity, polypharmacy, and PIM exposure was 59.1%, 24.1%, and 47.2%, respectively. Diuretics (10%), insulin sliding scale (8.8%), amitriptyline (7.8%), and aspirin (6.9%) were among the most frequently prescribed PIMs. Older patients experiencing pain flare-ups were more likely to have multimorbidity (adjusted odds ratio (AOR): 1.64, 95% confidence intervals: 1.13–2.39). Persistent anger (AOR: 3.33; 1.71–6.47) and use of mobility aids (AOR: 2.41, 1.35–4.28) were associated with polypharmacy. Moreover, cognitive impairment (AOR: 1.65, 1.15–2.34) and health deterioration (AOR: 1.61, 1.11–2.32) increased the likelihood of PIM exposure. High prevalence of multimorbidity and PIM use was observed in Ethiopia. Several important determinants that can be modified by applying PIM criteria in routine practice were also identified.

Prevalence of Polypharmacy and Risks of Potentially Inappropriate Medication Use in the Older Population in a Developing Country: A Systematic Review and Meta-Analysis

BACKGROUND AND AIM

Polypharmacy and potentially inappropriate medication (PIM) use in older populations (65+ years) have not yet been investigated by meta-analyses in developing countries. This systematic literature review and meta-analysis aimed to investigate the prevalence of polypharmacy and PIM use and major risk factors associated with PIM prescribing in older adults in Ethiopia.

METHODS

We searched PubMed/MEDLINE, Scopus, Embase, and Google Scholar databases to identify relevant studies published between January 1990 and October 2020. Observational studies reporting the prevalence and association of risk factors with polypharmacy and PIM use in the older population were meta-analyzed. A multilevel meta-analysis was conducted to pool the prevalence estimates, and the risk of PIM use was reported as a relative risk (RR) with a 95% confidence interval (CI).

RESULTS

We identified by systematic literature review 404 articles. Of those, 8 studies fulfilled inclusion criteria, comprising a total sample of 2,608 participants. The overall prevalence of polypharmacy and PIM use pooled by meta-analysis in the Ethiopian older population was 33 and 37%, respectively. The risk factors of PIM use were analyzed in the meta-analysis (particularly polymorbidity, polypharmacy, gender, and older age), and only older age of 65+ (RR: 1.71, 95% CI: 1.16-2.51) was significantly associated with PIM use.

CONCLUSION

This first meta-analysis from a developing country revealed a high prevalence of polypharmacy and PIM use in the Ethiopian older population. There was no awareness about the risk of PIMs in patients with polypharmacy and polymorbidity, and older age significantly predicted PIM use. Interventions ensuring rational geriatric pharmacotherapy are essential in developing countries in order to reduce the expected burden of PIM-related geriatric morbidity, higher costs, and mortality.

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.

Glycemic Control and its Predictors among Adult Diabetic Patients attending Mettu Karl Referral Hospital, Southwest Ethiopia: A Prospective Observational Study

INTRODUCTION

The current estimate is that 463 million people worldwide have diabetes. In 2017, an estimated 5 million (9.9%) deaths worldwide among adults were caused by diabetes. The burden of disease associated with uncontrolled diabetes is substantial in terms of mortality and cardiovascular disease. The aim of this study was to assess glycemic control level and its predictors among adult patients with diabetes.

METHODS

A prospective observational study was conducted among patients with diabetes during follow-up at an ambulatory clinic of Mettu Karl referral hospital from 15 April to 09 August 2019. The consecutive sampling method was used to collect data, following which the data were entered into Epidata manager version 4.4.2 and exported to the SPSS version 24.0 statistical software package for analysis. Logistic regression analysis was performed to identify predictors of poor glycemic control. Variables whose significance level was < 0.05 (p value) were considered to be predictors of poor glycemic control.

RESULTS

A total of 330 diabetic patients were included in the study, among whom 240 (72.7%) had poor glycemic control. The predictors of poor glycemic control in the multivariate logistic regression analysis were overweight [adjusted odds ratio (AOR) 4.07; 95% confidence interval (CI) 1.60, 10.36; p = 0.003], obesity (AOR 4.39; 95% CI 1.59, 12.14; p = 0.004), higher estimated glomerular filtration rate (eGFR) (AOR 2.34; 95% CI 1.23, 4.44; p = 0.010), type 1 diabetes (AOR 3.22; 95% CI 1.58, 6.55; p = 0.001), poor diet adherence (AOR 6.95; 95% CI 3.63, 13.32; p < 0.001) and non-adherence to medications (AOR 5.82; 95% CI 2.77, 12.26; p < 0.001).

CONCLUSION

Almost three-quarters of the study population of diabetic patients had poorly controlled blood sugar. Overweight, obesity, higher eGFR, type 1 diabetics, poor adherence to diet recommendation and non-adherence to medications were independent predictors of poor glycemic control. Educational strategies should focus on improving adherence to the recommended diet and medication(s), achieving weight control and optimizing glycemic control.

Baseline Prevalence of Polypharmacy in Older Hypertensive Study Subjects with Elevated Dementia Risk: Findings from the Risk Reduction for Alzheimer's Disease Study (rrAD)

BACKGROUND

Little is known about the prevalence of polypharmacy, the taking of five or more medications a day, in older adults with specific dementia risk factors.

OBJECTIVE

To examine the prevalence of polypharmacy in participants at baseline in a vascular risk reduction focused Alzheimer's disease (rrAD) trial targeting older patients with hypertension and elevated dementia risk.

METHODS

We conducted a detailed review of medications in a cross-sectional study of community-dwelling older adults with hypertension and elevated dementia risk. Medications were identified in a structured interview process with an onsite pharmacist or qualified designee. Polypharmacy was defined as use of five or more medications on a regular basis. Descriptive analyses were conducted on the sample as well as direct comparisons of subgroups of individuals with hypertension, diabetes, and hyperlipidemia.

RESULTS

The 514 rrAD participants, mean age 68.8 (standard deviation [sd] 6), reported taking different combinations of 472 unique medications at their baseline visit. The median number of medications taken by participants was eight [Range 0-21], with 79.2% exhibiting polypharmacy (n = 407). Sites differed in their prevalence of polypharmacy, χ2(3) = 56.0, p < 0.001. A nearly identical percentage of the 2,077 prescribed (51.8%) and over the counter (48.2%) medications were present in the overall medication profile. The presence of diabetes (87.5%), hyperlipidemia (88.2%), or both (97.7%) was associated with a higher prevalence of polypharmacy than participants who exhibited hypertension in the absence of either of these conditions (63.2%), χ2(3) = 35.8, p < 0.001.

CONCLUSION

Participants in a dementia risk study had high levels of polypharmacy, with the co-existence of diabetes or hyperlipidemia associated with a greater prevalence of polypharmacy as compared to having hypertension alone.

Prevalence and determinants of polypharmacy in cardiovascular patients attending outpatient clinic in Ethiopia University Hospital

BACKGROUND

While there are advances in medicine and pharmaceutical care, the burden of medication use has also grown with polypharmacy. In this regard, cardiovascular patients are subjected to polypharmacy for a longer period.

OBJECTIVE

The present study aimed to assess the prevalence and predictors of polypharmacy in cardiovascular outpatients attending the University of Gondar Comprehensive specialized hospital, northwest Ethiopia.

METHODS

A hospital-based cross-sectional study was employed at the University of Gondar Comprehensive Specialized Hospital from March 30 -May 30, 2019. The unique medical registration number of 424 patients was selected by using systematic random sampling to trace the medical chart and followed with an interview to explore the factors related to polypharmacy. All the Statistical analysis was carried out using Statistical Package for Social Sciences (SPSS) version 22. Bivariable and multivariable logistic regressions were used to identify the predictors of polypharmacy in cardiovascular patients.

RESULT

The mean age of the respondents was 56.83 ± 15.27 years. The mean number of medications per patient was 3.3±1.6. The prevalence of polypharmacy was 24.8% in cardiovascular outpatients while cardiovascular specific polypharmacy was 9.2%. Elderly (aged ≥ 65 years and above) patients were nearly two times more likely to had polypharmacy prescriptions with AOR: 1.97; 95% CI: 1.08-3.61; p = 0.027. Patients with abnormal weight (underweight AOR: 4.51; 95% CI: 1.42-14.30; p = 0.010, overweight AOR: 3.78; 95% CI: 1.83-7.83; p<0.001 and obese AOR: 5.1; 95% CI: 2.04-12.75 p<0.001) are more likely to have polypharmacy. Having a family history of CVD increase the likelihood of polypharmacy more than double; AOR: 2.40; 95% CI: 1.17-4.93; p = 0.017. A unit increase in Charlson comorbidity index score resulted in a nearly threefold likelihood of polypharmacy with AOR: 2.83; 95% CI 1.91-3.89; p<0.001.

CONCLUSION

One out of four cardiovascular patients attending the outpatient clinic was on polypharmacy. The elderly age, abnormal body mass index (non-normal weight), family history of cardiovascular diseases and increasing Charlson morbidity index were the predictors of polypharmacy in cardiovascular patients. Clinicians should ensure the relevance of all prescribed medications and pharmaceutical care targeting at the prevention of inappropriate polypharmacy would be pivotal to reduce polypharmacy associated burdens.

Benefits, risks and impacts on quality of life of medications used in multimorbid older adults: a Delphi study

Background Multimorbidity and polypharmacy are common in older people. Despite the existence of quality criteria for medication use among this population, there is little guidance for managing the complex pharmacological arsenal in a multimorbidity context. Objective To establish consensus on benefits, risks and impacts on quality of life of medications used in an older adult with three chronic diseases that require complex pharmacotherapy. Setting International experts in pharmacology. Method A panel of experts responded to three rounds of a Delphi survey. They assessed the benefits, risks and positive impacts on quality of life of 50 different medications or medication classes that could be used by a hypothetical multimorbid older patient aged 65-75 years, with type 2 diabetes, heart failure and chronic obstructive pulmonary disease. Each aspect was evaluated on a 5-level Likert scale. Main outcome measure Percentage of agreement on each of the three aspects for all medication. Results Consensus was reached on 95% of items (166/174). Only two medication classes were associated with both the highest category of benefits and positive impacts on quality of life, and the lowest risk category: long-acting anticholinergics and long-acting beta-2-agonists. Nine other medications/classes of medications were categorized within the highest benefits level (metformin, DPP-4-inhibitors, short-acting beta-2-agonists, ACE inhibitors, beta-blockers, warfarin, non-vitamin K oral anticoagulants, nitrates and acetaminophen). Fifteen medications were included in the highest level of risks, among which warfarin and Non-vitamin K oral anticoagulants. Conclusions Medications recommended in clinical guidelines for individual diseases are generally considered positive for multimorbid older patients. Nevertheless, a non-negligible number of medications was deemed negative or very negative by our panelists. For multimorbid patients, individualizing treatment according to their preferences seems of utmost importance.

Factors Associated with Health-Related Quality of Life in Community-Dwelling Older Adults: A Multinomial Logistic Analysis

The main aim of this study was to determine the association of various clinical, functional and pharmacological factors with the physical (PCS) and mental (MCS) summary components of the health-related quality of life (HRQoL) of community-dwelling older adults. Design: Cross-sectional study. Patients and setting: Sample of 573 persons aged over 65 years, recruited at 12 primary healthcare centres in Málaga, Spain. Sociodemographic, clinical, functional, and comprehensive drug therapy data were collected. The main outcome was HRQoL assessed on the basis of the SF-12 questionnaire. A multinomial logistic regression model was constructed to study the relationship between independent variables and the HRQoL variable, divided into intervals. The average self-perceived HRQoL score was 43.2 (± 11.02) for the PCS and 48.5 (± 11.04) for the MCS. The factors associated with a poorer PCS were dependence for the instrumental activities of daily living (IADL), higher body mass index (BMI), number of medications, and presence of osteoarticular pathology. Female gender and the presence of a psychopathological disorder were associated with worse scores for the MCS. The condition that was most strongly associated with a poorer HRQoL (in both components, PCS and MCS) was that of frailty (odds ratio (OR) = 37.42, 95% confidence interval (CI) = 8.96–156.22, and OR = 20.95, 95% CI = 7.55–58.17, respectively). It is important to identify the determinant factors of a diminished HRQoL, especially if they are preventable or modifiable.
