Sarcopenia is associated with a greater risk of polypharmacy and number of medications: a systematic review and meta-analysis

Polypharmacy in older adults is associated with multiple negative consequences that may affect muscular function, independently from the presence of medical conditions. The aim of this systematic review and meta-analysis was to investigate the association of sarcopenia with polypharmacy and higher number of medications. A systematic literature search of observational studies using PubMed, Web of Science, Scopus and Cochrane Library databases was conducted from inception until June 2022. To determine if sarcopenia is associated with a higher risk of polypharmacy and increased number of medications, a meta-analysis using a random-effects model was used to calculate the pooled effects (CRD42022337539). Twenty-nine studies were included in the systematic review and meta-analysis. Sarcopenia was associated with a higher prevalence of polypharmacy (odds ratio [OR]: 1.65, 95% confidence interval [CI] [1.23, 2.20], I2 = 84%, P < 0.01) and higher number of medications (mean difference: 1.39, 95% CI [0.59, 2.19], I2 = 95%, P < 0.01) compared with individuals without sarcopenia. Using meta-regression, a high variance was observed due to different populations (i.e., community-dwelling, nursing home residents, inpatients, outpatients) for both outcomes of polypharmacy (r = −0.338, SE = 0.1669, 95% CI [−0.67, −0.01], z = −2.03, P = 0.04) and number of medications (r = 0.589, SE = 0.2615, 95% CI [0.08, 1.10], z = 2.25, P = 0.02). This systematic review and meta-analysis reported a significantly increased risk of polypharmacy and higher number of medications in people with sarcopenia compared with individuals without this condition. Future research should clarify whether the specificity and number of medications is a direct contributor in accelerating the progression of muscle wasting and dysfunction contributing to sarcopenia in older adults

Polypharmacy and Clinical Outcomes in Hospitalized Patients With Acute Decompensated Heart Failure

BACKGROUND: Polypharmacy is a common problem among patients with acute decompensated heart failure (ADHF) who often have multiple comorbidities. OBJECTIVE: The aim of this study was to define the number of medications at hospital discharge and whether it is associated with clinical outcomes at 1 year. METHODS: We evaluated the number of medications in 2578 patients with ADHF who were ambulatory at hospital discharge in the Kyoto Congestive Heart Failure Registry and compared 1-year outcomes in 4 groups categorized by quartiles of the number of medications (quartile 1, ≤ 5; quartile 2, 6-8; quartile 3, 9-11; and quartile 4, ≥ 12). RESULTS: At hospital discharge, the median number of medications was 8 (interquartile range, 6-11) with 81.5% and 27.8% taking more than 5 and more than 10 medications, respectively. The cumulative 1-year incidence of a composite of death or rehospitalization (primary outcome measure) increased incrementally with an increasing number of medications (quartile 1, 30.8%; quartile 2, 31.6%; quartile 3, 39.7%; quartile 4, 50.3%; P < .0001). After adjusting for confounders, the excess risks of quartile 4 relative to those of quartile 1 remained significant (P = .01). CONCLUSIONS: In the contemporary cohort of patients with ADHF in Japan, polypharmacy at hospital discharge was common, and excessive polypharmacy was associated with a higher risk of mortality and rehospitalizations within a 1-year period. Collaborative disease management programs that include a careful review of medication lists and an appropriate deprescribing protocol should be implemented for these patients

Is there a relationship between periodontal conditions and number of medications among the elderly?

Objective: To investigate possible correlations of clinical attachment level and pocket depth with number of medications in elderly individuals.Methods: Intra-oral examinations for 139 patients visiting Tufts dental clinic were done. Periodontal assessments were performed with a manual UNC-15 periodontal probe to measure probing depth (PD) and clinical attachment level (CAL) at 6 sites. Complete lists of patients’ medications were obtained during the examinations. Statistical analysis involved Kruskal-Wallis, chi square and multivariate logistic regression analyses.Results: Age and health status attained statistical significance (p&lt; 0.05), in contingency table analysis with number of medications. Number of medications had an effect on CAL: increased attachment loss was observed when 4 or more medications were being taken by the patient. Number of medications did not have any effect on periodontal PD. In multivariate logistic regression analysis, 6 or more medications had a higher risk of attachment loss (&gt;3mm) when compared to the no-medication group, in crude OR (1.20, 95% CI:0.22-6.64), and age adjusted (OR=1.16, 95% CI:0.21-6.45), but not with the multivariate model (OR=0.71, 95% CI:0.11-4.39).Conclusion: CAL seems to be more sensitive to the number of medications taken, when compared to PD. However, it is not possible to discriminate at exactly what number of drug combinations the breakdown in CAL will happen. We need to do further analysis, including more subjects, to understand the possible synergistic mechanisms for different drug and periodontal responses.Keywords: periodontal disease, medications, elderly, clinical attachment level, probing dept

Association between number of medications and mortality in geriatric inpatients : a Danish nationwide register-based cohort study

Key summary pointsAim To explore the association between number of medications and mortality in geriatric inpatients when adjusted for diseases and activities of daily living. Findings Increasing number of medications is associated with increased mortality. Every increase in number of medications by one is associated with a 3% increase in overall mortality. Message Evaluation of polypharmacy is important part of geriatric assessment when older adults are hospitalized. Purpose To explore the association between the number of medications and mortality in geriatric inpatients taking activities of daily living and comorbidities into account. Methods A nationwide population-based cohort study was performed including all patients aged >= 65 years admitted to geriatric departments in Denmark during 2005-2014. The outcome of interest was mortality. Activities of daily living using Barthel Index (BI) were measured at admission. National health registers were used to link data on an individual level extracting data on medications, and hospital diseases. Patients were followed to the end of study (31/12/2015), death, or emigration, which ever occurred first. Kaplan-Meier survival curves were used to estimate crude survival proportions. Univariable and multivariable analyses were performed using Cox regression. The multivariable analysis were adjusted for age, marital status, period of hospital admission, BMI, and BI (model 1), and additionally either number of diseases (model 2) or Charlson comorbidity index (model 3). Results We included 74,603 patients (62.8% women), with a median age of 83 (interquartile range [IQR] 77-88) years. Patients used a median of 6 (IQR 4-9) medications. Increasing number of medications was associated with increased overall, 30-day, and 1-year mortality in all three multivariable models for both men and women. For each extra medication, the mortality increased by 3% in women and 4% in men in the fully adjusted model. Conclusion Increasing number of medications was associated with mortality in this nationwide cohort of geriatric inpatients. Our findings highlight the importance of polypharmacy in older patients with comorbidities

Is who you ask important? Concordance between survey and registry data on medication use among self- and proxy-respondents in the longitudinal study of aging Danish twins and the Danish 1905-cohort study

This work was supported by the U.S. National Institute of Health (P01AG031719, R01AG026786 and 2P01AG031719), the VELUX Foundation, and the Max Planck Society within the framework of the project “On the edge of societies: New vulnerable populations, emerging challenges for social policies and future demands for social innovation. The experience of the Baltic Sea States (2016–2021).”Background This study investigates the accuracy of the reporting of medication use by proxy- and self-respondents, and it compares the prognostic value of the number of medications from survey and registry data for predicting mortality across self- and proxy-respondents. Methods The study is based on the linkage of the Longitudinal Study of Aging Danish Twins and the Danish 1905–Cohort Study with the Danish National Prescription Registry. We investigated the concordance between survey and registry data, and the prognostic value of medication use when assessed using survey and registry data, to predict mortality for self- and proxy-respondents at intake surveys. Results Among self-respondents, the agreement was moderate (κ = 0.52–0.58) for most therapeutic groups, whereas among proxy-respondents, the agreement was low to moderate (κ = 0.36–0.60). The magnitude of the relative differences was, generally, greater among proxies than among self-respondents. Each additional increase in the total number of medications was associated with 7%–8% mortality increase among self- and 4%–6% mortality increase among proxy-respondents in both the survey and registry data. The predictive value of the total number of medications estimated from either data source was lower among proxies (c-statistic = 0.56–0.58) than among self-respondents (c-statistic = 0.74). Conclusions The concordance between survey and registry data regarding medication use and the predictive value of the number of medications for mortality were lower among proxy- than among self-respondents.Publisher PDFPeer reviewe

Community-dwelling older people’s attitudes towards deprescribing in Canada

Background: While there is evidence that supervised withdrawal of inappropriate medications might be beneficial for individuals with polypharmacy, little is known about their attitudes towards deprescribing. Objective: This study aimed to describe the situation among older community-dwelling Canadians. Methods: A self-administered survey was adapted from the Patients’ Attitudes Towards Deprescribing questionnaire and distributed to 10 community pharmacies and 2 community centers. The participants rated their agreement on statements about polypharmacy/deprescribing on a 5-point, Likert-type scale. Correlations between the desire to have medications deprescribed and survey items were evaluated using Spearman’s Rho and Goodman and Kurska’s gamma rank correlations. Results: From the 129 participants, 63% were women [median age: 76 (IQR:71–80); median number medication: 6 (IQR: 3–8)]. A proportion of 50.8% (95%CI: 41.6%–60.0%) expressed the desire to reduce their number of medications. This desire was strongly correlated with the individuals’ feeling of taking a large number of medications and moderately correlated with the belief that some of the medications were no longer needed or that they were experiencing side effects. Conclusions: The results show that older individuals in the community are eager to undertake deprescribing, especially if they have a large number of medications, are experiencing side effects or feel some medications are no longer necessary

Drug-drug interactions and potentially inappropriate medications among elderly outpatients

The high prevalence of concomitant chronic illnesses and the resulting higher number of medications in the elderly population increase the risk of adverse drug reactions due to drug-drug interactions (DDIs) and potentially inappropriate medications (PIMs). Therefore, the aim of this study was to investigate the prevalence and factors associated with DDIs and PIMs in outpatient geriatrics. In this cross-sectional study, 1512 prescriptions belonging to patients aged ≥65 years from five public pharmacies in Tehran were evaluated. Clinically relevant (C, D, and X) and significant DDIs (D and X) were documented according to the Lexicomp®. Additionally, Zhan criteria were used to detect PIMs. At least one clinically relevant DDI was detected in 61.7% of the prescriptions containing ≥2 medications. The largest percentage of prescriptions with DDIs was prescribed by cardiologists (74.3%). The number of medications in prescriptions and the specialty of the prescriber significantly affected both clinically relevant and significant DDIs in a logistic regression model. At least one PIM was identified in 16.3% of the prescriptions. General practitioners (GPs) were the largest prescribers of PIMs. The mean number of medications was significantly higher in prescriptions with PIMs. In conclusion, clinically relevant DDIs are frequent in the elderly. In terms of PIMs, more attention should be paid to the education of GPs

Non-adherence to cardiovascular pharmacotherapy in Iraq assessed using 8-items Morisky questionnaire and analysis of dried blood spot samples

open access journalThe study evaluated the non-adherence to selected cardiovascular medications, atenolol, atorvastatin, bisoprolol, diltiazem, lisinopril, simvastatin and valsartan in Iraqi patients by applying a standardized Morisky questionnaire (8-MMAS) and by measuring therapeutic drug concentrations in dried blood spots (DBS) analyzed by liquid chromatography - high resolution mass spectrometry (LC-HRMS). Sixty-nine patients, on continued use of one or more of the selected drugs, were evaluated. The questionnaire showed that 21.7% of participants were non-adherent whereas DBS analysis showed that 49.3% were non-adherent to their medications. No significant correlation between medication non-adherence and gender was detected, but adherence was negatively correlated with the number of medications in the regimen. The 8-items questionnaire was unable to differentiate non-adherence to multiple medications in the prescribed pharmacotherapy regimens. DBS is an alternative to conventional methods to monitor non-adherence objectively. Agreement between the two approaches was weak (Kappa =0.269, p-value 0.05)

Polypharmacy in elderly women after myocardial infarction.

The aims of the study were to: (a) examine the number, absolute volume, and type of daily medications older women were taking 6 to 12 months post-myocardial infarction (MI); (b) describe the financial burden of cardiac medications; and (c) examine the relationship of age, education, and income to the number of medications. An analysis of a cross-sectional descriptive study of women &gt;65 years of age who were post-MI was used. Most (89%; N = 83) were taking at least one cardiac medication, costs per day varied ($0.13–$6.75), and total number of pills taken per day was 1 to 19. Age, education, and income did not explain the number of medications. Consideration of the financial burden of medications is important to increase compliance and foster secondary prevention in older women
