Prevalencia de polifarmacia y factores asociados en adultos mayores en España: datos de la Encuesta Nacional de Salud 2017

Prevalence of potentially inappropriate medications and prescription dynamics in elderly hospitalized patients in Spain

PURPOSE

In recent years, the need for a more appropriate prescription of medications in the older population has emerged as a significant public health concern. In this study, we aimed to evaluate the prevalence of potentially inappropriate medications (PIM) in hospitalized adults aged ≥ 75.

PATIENTS AND METHODS

This was a retrospective descriptive observational study of patients at 16 hospitals in Spain. The study population included inpatients aged ≥ 75 admitted during a 7-day period (May 10 to 16, 2021). Data were obtained from the pharmacy databases of the participating hospitals. The list of PIMs was based on the Beers, STOPP-START, EU-PIM and PRISCUS criteria.

RESULTS

A total of 4,183 patients were included. PIMs were detected in 23.5% (N = 1,126) of the cohort. The prevalence rates at the participating hospitals ranged from 10% to 42.5%. The PIM/patient ratio was 1.2. The most common PIMs were midazolam, dexketoprofen, diazepam, and doxazosin, all of which (except for doxazosin) were more common in women. Benzodiazepines accounted for 70% of all PIMs. In 35% of cases, the PIMs were initiated before hospital admission. Of the 818 PIMs initiated during hospitalization, the two most common were benzodiazepines (49%) and anti-inflammatory drugs (25%). At discharge, only 4.9% of the PIMs initiated during the hospital stay were still prescribed.

CONCLUSION

In this population of older hospitalized patients, the overall prevalence of PIMs was moderate. However, the prevalence rate at the participating hospitals was highly variable. In most cases, PIMs prescribed prior to hospitalization for chronic conditions were not withdrawn during the hospital stay. No significant increase in PIMs was observed from pre-admission to post-discharge. These findings underscore the need for multidisciplinary interventions to optimize the pharmaceutical treatment in older adults in the hospital setting to reduce the consequences of PIMs in patients.

A real-world analysis of pharmacotherapy adherence and the factors influencing it in Serbia: a nationwide, population-based, cross-sectional study

Introduction

Monitoring the pharmacotherapy adherence in society is crucial for identifying occurance and causes of potential inadequate use of drugs and inform providers about the need for better customer counceling. It is necessary component of the strategic planning of the quality of healthcare services. This population- based study aimed to assess the medication intake adherence in the Republic of Serbia and the individual factors and health system variables influencing its pattern.

Methods

We applied a cross-sectional approach to study medication intake adherence using a secondary analysis of the latest 2019 Serbian National Health Survey data. The statistical modeling of the pharmacotherapy adherence incorporated sociodemographic data, self-reported disease, and lifestyle behavior.

Results

In 2019, in the representative sample of 12,066 adults in Serbia, requiring prescribed medicine, 49.8% did comply with the prescribed drugs, and 50.2% do not. Participants who adhered to prescribed medication were significantly (p < 0.001) older (62.4 ± 14 years), predominantly female (55.3%), had secondary education (48.5%), resided in southern and eastern parts of Serbia (55.5%), and belonged to the lowest income quintile (21.4%). The participants most often take prescribed drugs for hypertension (64.1%) and lower back pain (30.5%), while around 20% take medication for coronary disease, diabetes mellitus, and high blood cholesterol. About 85-92% of participants with financial or general difficulties using prescribed medication.

Conclusion

There is poor medication intake adherence to prescribed medication in Serbia. Gender, age, and region determine the adherence. Also, health-related and healthcare system-related factors impact the use of prescribed medication. Study findings can inform planning the counceling interventions in the target groups where improving medication adherence is necessary, as well as to enhance training of healthcare providers about pharmacotherapy adherence.

Defining, identifying and addressing problematic polypharmacy within multimorbidity in primary care: a scoping review

INTRODUCTION

Polypharmacy and multimorbidity pose escalating challenges. Despite numerous attempts, interventions have yet to show consistent improvements in health outcomes. A key factor may be varied approaches to targeting patients for intervention.

OBJECTIVES

To explore how patients are targeted for intervention by examining the literature with respect to: understanding how polypharmacy is defined; identifying problematic polypharmacy in practice; and addressing problematic polypharmacy through interventions.

DESIGN

We performed a scoping review as defined by the Joanna Briggs Institute.

SETTING

The focus was on primary care settings.

DATA SOURCES

Medline, Embase, Cumulative Index to Nursing and Allied Health Literature and Cochrane along with ClinicalTrials.gov, Science.gov and WorldCat.org were searched from January 2004 to February 2024.

ELIGIBILITY CRITERIA

We included all articles that had a focus on problematic polypharmacy in multimorbidity and primary care, incorporating multiple types of evidence, such as reviews, quantitative trials, qualitative studies and policy documents. Articles focussing on a single index disease or not written in English were excluded.

EXTRACTION AND ANALYSIS

We performed a narrative synthesis, comparing themes and findings across the collective evidence to draw contextualised insights and conclusions.

RESULTS

In total, 157 articles were included. Case-finding methods often rely on basic medication counts (often five or more) without considering medical history or whether individual medications are clinically appropriate. Other approaches highlight specific drug indicators and interactions as potentially inappropriate prescribing, failing to capture a proportion of patients not fitting criteria. Different potentially inappropriate prescribing criteria also show significant inconsistencies in determining the appropriateness of medications, often neglecting to consider multimorbidity and underprescribing. This may hinder the identification of the precise population requiring intervention.

CONCLUSIONS

Improved strategies are needed to target patients with polypharmacy, which should consider patient perspectives, individual factors and clinical appropriateness. The development of a cross-cutting measure of problematic polypharmacy that consistently incorporates adjustment for multimorbidity may be a valuable next step to address frequent confounding.

Prevalence of multimorbidity and polypharmacy among adults and older adults: a systematic review

Multimorbidity (multiple conditions) and polypharmacy (multiple medications) are increasingly common, yet there is a need to better understand the prevalence of co-occurrence. In this systematic review, we examined the prevalence of multimorbidity and polypharmacy among adults (≥18 years) and older adults (≥65 years) in clinical and community settings. Six electronic databases were searched, and 87 studies were retained after two levels of screening. Most studies focused on adults 65 years and older and were done in population-based community settings. Although the operational definitions of multimorbidity and polypharmacy varied across studies, consistent cut-points (two or more conditions and five or more medications) were used across most studies. In older adult samples, the prevalence of multimorbidity ranged from 4·8% to 93·1%, while the prevalence of polypharmacy ranged from 2·6% to 86·6%. High heterogeneity between studies indicates the need for more consistent reporting of specific lists of conditions and medications used in operational definitions.

Spanish version of the Self-Care of Chronic Illness Inventory: A validation study amongst community-dwelling older adults with chronic multimorbidity

AIM

To psychometrically assess the Spanish version of the Self-Care of Chronic Illness Inventory (SC-CII-Sp) in community-dwelling older adults with chronic multimorbidity.

DESIGN

A methodological study.

METHOD

A total of 1260 older adults participated in the study between May 2020 and February 2022. The data were analysed using SPSS Statistics® 26 and AMOS® 24. The items' content validity index and the Fleiss' kappa were calculated to assess the SC-CII-Sp's content validity. Convergent validity was assessed by calculating the Pearson correlation coefficient between the participants' scores on the SC-CII-Sp and their scores on the Spanish Chronic Disease Self-Efficacy scale (SCD-SE). Construct validity was tested by performing a confirmatory factor analysis (CFA). The SC-CII-Sp's reliability was tested by computing the Cronbach's alpha.

RESULTS

The SC-CII-Sp showed good content and convergent validity. The CFA showed that the SC-CII-Sp has three sub-scales. The 8-item Self-Care Maintenance sub-scale has good internal consistency and is comprised of two dimensions: illness-related and health-promoting behaviour. The Self-Care Monitoring sub-scale had excellent internal consistency and its five loaded items belonged to a single dimension. The 6-item Self-Care Management sub-scale has adequate internal consistency and two dimensions: autonomous and consulting behaviour.

CONCLUSION

The Spanish version of SC-CII is a valid and reliable instrument to be used in the assessment of self-care behaviours amongst Spanish-speaking, community-dwelling older adults with chronic multimorbidity.

IMPLICATIONS FOR THE PROFESSION

Nurses need valid and reliable tools to assess self-care behaviours in Spanish-speaking community-dwelling older adults with chronic multimorbidity. This study provides a 19-item tool that allows for the comprehensive evaluation of self-care behaviours in healthy and ill states.

IMPACT

Using the SC-CII-Sp in clinical or research settings could help nurses to examine the effects of different interventions on self-care behaviours amongst Spanish-speaking, community-dwelling older adults with chronic multimorbidity.

Feasibility study of a clinical decision support system for polymedicated patients in primary care

Age-related changes in pharmacokinetics and pharmacodynamics, multimorbidity, frailty, and cognitive impairment represent challenges for drug treatments. Moreover, older adults are commonly exposed to polypharmacy, leading to increased risk of drug interactions and related adverse events, and higher costs for the healthcare systems. Thus, the complex task of prescribing medications to older polymedicated patients encourages the use of Clinical Decision Support Systems (CDSS). This paper evaluates the CDSS miniQ for identifying potentially inappropriate prescribing in poly-medicated older adults and assesses the usability and acceptability of the system in health care professionals, patients, and caregivers. The results of the study demonstrate that the miniQ system was useful for Primary Care physicians in significantly improving prescription, thereby reducing potentially inappropriate medication prescriptions for elderly patients. Additionally, the system was found to be beneficial for patients and their caregivers in understanding their medications, as well as usable and acceptable among healthcare professionals, patients, and caregivers, highlighting the potential to improve the prescription process and reduce errors, and enhancing the quality of care for elderly patients with polypharmacy, reducing adverse drug events, and improving medication management.

The subjective perception of the happiness of older adult residents in Colombia

Introduction

Happiness is understood as the perception of subjective well-being, it can be a quality, a result, or a state characterized by well-being or satisfaction that every person wants to achieve. In older adults, this satisfaction is a sum of lifelong achievements and triumphs; However, some factors influence this ideal.

Objective

Analyze demographic, family, social, personal, and health factors associated with the subjective perception of happiness in older adults, using data from a study conducted in five cities in Colombia, in order to make a theoretical contribution in the search for improvement of their physical, mental and social health.

Materials and methods

A quantitative, cross-sectional, analytical study was carried out, using primary source information, obtained with 2,506 surveys from voluntary participants aged 60 and over, who had no cognitive impairment, and who reside in urban areas but not in long-term centers. The variable happiness (classified as high or moderate/low) was used for: (1) A univariate explorative characterization of older adult, (2) a bivariate estimation of the relationships with the factors studied, and (3) a multivariate construction of profiles through multiple correspondences.

Results

67.2% reported high happiness levels, with differences by city: Bucaramanga (81.6%), Pereira (74.7%), Santa Marta (67.4), Medellín (64%), and Pereira (48.7%). Happiness was explained by the absence of risk of depression and little hopelessness, strengthened psychological well-being, a perception of high quality of life, and living in a functional family.

Conclusion

This study provided an overview of possible factors that can be enhanced and strengthened with public policies (structural determinant), community empowerment, family strengthening (intermediate determinant), and educational programs (proximal determinant). These aspects are included in the essential functions of public health, in favor of mental and social health in older adults.

Cross-cultural adaptation and validation of the Recognizing And Addressing Limited Pharmaceutical Literacy (RALPH) interview guide in community pharmacies

BACKGROUND

The RALPH (Recognizing and Addressing Limited PHarmaceutical Literacy) interview guide makes it possible to identify patients with limited pharmaceutical knowledge and to assess their skills in the functional, communicative, and critical health literacy domains.

OBJECTIVE

(s): To perform a cross-cultural validation of the RALPH interview guide in Spanish population; to conduct a descriptive analysis based on patients' responses.

METHODS

A cross-sectional study of patients' pharmaceutical literacy skills was conducted in three stages: systematic translation, administration of the interview and analysis of psychometric properties. The target population included adult patients (≥18 years) who attend one of the participating community pharmacies in Barcelona (Spain). Content validity was evaluated by an expert committee. Viability was assessed in the pilot test, and reliability was assessed using internal consistency and intertemporal stability. Construct validity was assessed by factor analysis.

RESULTS

A total of 103 patients were interviewed at 20 pharmacies. Cronbach's alpha values based on standardized items ranged between 0.720 and 0.764. For the longitudinal component, the ICC test-retest reliability was 0.924. The factor analysis was verified by KMO (0.619) and Bartlett's test of sphericity (P-value <0.05). The definitive RALPH guide translated into Spanish maintains the same structure as the original. Some expressions were simplified, and the questions on the comprehension of warnings or specific instructions for use, contradictory information and shared decision-making were reformulated. Pharmaceutical literacy skills were seen to be most limited with regard to the critical domain. The responses of the Spanish patients were in agreement with the original results of the RALPH interview guide.

CONCLUSIONS

The RALPH interview guide in Spanish complies with the requirements viability, validity, and reliability. This tool may be able to identify the low pharmaceutical literacy skills of patients coming to community pharmacies in Spain, and its use may also be extended to other Spanish-speaking countries.

Polypharmacy and associated factors: a gender perspective in the elderly Spanish population (2011-2020)

Background: Few studies have examined the epidemiology of polypharmacy in non-institutionalized elderly adults with regard to sex differences. This study aimed to identify the prevalence of polypharmacy among people ≥65 years old residing in Spain, analyze trends in that prevalence from 2011/12 to 2020, describe the use of the medicines involved and study the possible relationship between polypharmacy and certain sociodemographic, health-related variables, as well as the use of care services by sex. Methods: A nationwide cross-sectional study with 21,841 non-institutionalized people ≥65 years old from the Spanish National Health Survey (2011/2012 and 2017) and the European Health Survey in Spain (2014 and 2020) was performed. We used descriptive statistics, performing two binary logistic regressions to determine the factors related to polypharmacy. Results: The prevalence of polypharmacy was 23.2% (women: 28.1%, men: 17.2%; p < 0.001). The most commonly consumed medicines were analgesics and tranquillizers, relaxants or sleeping pills in elderly women, compared with antihypertensives, antacids and antiulcer drugs and statins for elderly men. In both sexs, the positive predictors of polypharmacy included average, poor and very poor self-perceived states of health, people with overweight and obesity, being severely/non-severely limited due to a health problem, having ≥ three chronic conditions, visits to the family doctor and hospitalization. Among elderly women, negative predictors were alcohol intake, whereas in elderly men positive predictors were being 75-84 years old, being current smokers and having 1, 2 chronic conditions. Conclusion: Polypharmacy has a prevalence of 23.2%, with women accounting for 28.1% and men 17.2% of the total. Knowledge of positive and negative predictors of polypharmacy have important implications for public health efforts to develop or improve health guidelines and strategies for promoting the proper use of medication, particularly in the elderly population by sex.

Factors related to polypharmacy and hyper-polypharmacy for the elderly: A nationwide cohort study using National Health Insurance data in South Korea

Polypharmacy may cause adverse health outcomes in the elderly. This study examined the prevalence of continuous polypharmacy and hyper-polypharmacy, factors associated with polypharmacy, and the most frequently prescribed medications among older adults in South Korea. This was a retrospective observational study using National Health Insurance claims data. In total, 7,358,953 Korean elderly patients aged 65 years and older were included. Continuous polypharmacy and hyper-polypharmacy were defined as the use of ≥5 and ≥10 medications, respectively, for both ≥90 days and ≥180 days within 1 year. A multivariate logistic regression analysis was conducted with adjustment for general characteristics (sex, age, insurance type), comorbidities (12 diseases, number of comorbidities, and Elixhauser Comorbidity Index [ECI] classification), and healthcare service utilization. Among 7.36 million elderly patients, 47.8% and 36.9% had polypharmacy for ≥90 and ≥180 days, and 11.9% and 7.1% of patients exhibited hyper-polypharmacy for ≥90 and ≥180 days, respectively. Male sex, older age, insurance, comorbidities (cardio-cerebrovascular disease, diabetes mellitus, depressive disorder, dementia, an ECI score of ≥3), and healthcare service utilization were associated with an increased probability of polypharmacy. The therapeutic class with the most prescriptions was drugs for acid-related disorders (ATC A02). The number of outpatient visit days more strongly influenced polypharmacy than hospitalizations and ED visits. This study provides health policymakers with important evidence about the critical need to reduce polypharmacy among older adults.

Probiotics Treatment Can Improve Cognition in Patients with Mild Cognitive Impairment: A Systematic Review

Background: In recent years, the existence of the gut-brain axis and the impact of intestinal microbiota on brain function has received much attention. Accumulated evidence has prompted the postulation of the infectious hypothesis underlying or facilitating neurodegenerative diseases, such as Alzheimer’s disease. Under this hypothesis, intervention with probiotics could be useful at a preventive and therapeutic level. Objective: The objective of this systematic review is to reveal a benefit of improved cognitive function following the use of probiotics in individuals with mild cognitive impairment. Methods: We searched bibliographic databases and analyzed in detail the evidence and methodological quality of five recent randomized, double-blind, placebo-controlled clinical trials using the Cochrane Tool and the SIGN checklist. Results: Overall, and with satisfactory methodological quality, the studies evaluated support the use of probiotics as a weapon to slow the progression of cognitive decline in subjects with mild cognitive impairment. The literature review also indicates that maximum benefit of probiotics is found in subjects with incipient cognitive dysfunction and has no effect in those with advanced disease or absence of disease. Conclusion: These results support the intervention with probiotics, especially as a preventive approach. However, caution is required in the interpretation of the results as microbiota has not been evaluated in all studies, and further large-scale research with a prolonged study period is necessary to ensure the translatability of the results into real practice.

Development of a Clinical Prediction Rule for Adverse Events in Multimorbid Patients in Emergency and Hospitalisation

(1) Background: There is currently a global consensus that the quality of comprehensive care for acutely hospitalised elderly people should include addressing functionality and mobility, cognitive status, prevention of pressure ulcers, urinary incontinence, falls and delirium, as well as pain control and medication-related problems. The aim of this study is to develop and validate a clinical prediction rule for multimorbid patients admitted to an acute care hospital unit for any of the five adverse events included in our vulnerability pentad: falls, pressure ulcers, urinary incontinence, pain and delirium. (2) Methods: Longitudinal analytical clinimetric study, with two cohorts. The study population will consist of multimorbid patients hospitalised for acute care, referred from the Emergency Room. A clinical prediction rule will be proposed, incorporating predictive factors of these five adverse outcomes described. This study has received funding, awarded in November 2020 (PI-0107-2020), and was approved in October 2019 by the Research Ethics Committee ″Costa del Sol″. (3) Conclusions: Preventing adverse events in hospitalised patients is particularly important for those with multimorbidity. By applying a clinical prediction rule to detect specific risks, an estimate can be obtained of their probability of occurrence.

The patterns and implications of potentially suboptimal medicine regimens among older adults: a narrative review

In the context of an ageing population, the burden of disease and medicine use is also expected to increase. As such, medicine safety and preventing avoidable medicine-related harm are major public health concerns, requiring further research. Potentially suboptimal medicine regimens is an umbrella term that captures a range of indicators that may increase the risk of medicine-related harm, including polypharmacy, underprescribing and high-risk prescribing, such as prescribing potentially inappropriate medicines. This narrative review aims to provide a background and broad overview of the patterns and implications of potentially suboptimal medicine regimens among older adults. Original research published between 1990 and 2021 was searched for in MEDLINE, using key search terms including polypharmacy, inappropriate prescribing, potentially inappropriate medication lists, medication errors, drug interactions and drug prescriptions, along with manual checking of reference lists. The review summarizes the prevalence, risk factors and clinical outcomes of polypharmacy, underprescribing and potentially inappropriate medicines. A synthesis of the evidence regarding the longitudinal patterns of polypharmacy is also provided. With an overview of the existing literature, we highlight a number of key gaps in the literature. Directions for future research may include a longitudinal investigation into the risk factors and outcomes of extended polypharmacy, research focusing on the patterns and implications of underprescribing and studies that evaluate the applicability of tools measuring potentially inappropriate medicines to study settings.

[Potentially inappropriate prescribing: Usefulness of STOPP/START criteria version 2 in Catalonian elderly population]

OBJECTIVE

To measure the prevalence of potentially inappropriate prescribing (PIP) among the elderly population in Catalonia using criteria Screening Tool of Older Person's Prescriptions/Screening Tool to Alert doctors to Right Treatment (STOPP/START) version 2. In addition, to evaluate the association between PIP and several factors (polypharmacy, gender, age and sociodemographic conditions).

MATERIALS AND METHODS

Design: Retrospective cross sectional population study.

SETTINGS

Primary Health Care, Catalonia, Spain.

PARTICIPANTS

The study population comprised of participants 70 years old and over, who attended primary health care centres in Catalonia in 2014 (700.058 patients).

MAIN ANALYSIS

55 STOPP and 19 START criteria are applied to analyse PIP prevalence. Logistic regression models are adjusted to determine PIP association with several factors.

RESULTS

The mean age is 79. 2±6.5. 58.5% being female. 38.7% of patients have 7 or more prescribed drugs, whereas 50% go to a primary care centre 10 or more times during one year. The most frequent PIP among STOPP criteria are related to nonsteroidal anti-inflammatory drug intake, antiplatelet and anticoagulants use, and benzodiazepines. According to START, the most frequent omissions are vitamin D and calcium supplements, antidepressants, and cardiovascular medications. Factors that increase PIP are: female gender, living in a nursing home, receiving home health care, polypharmacy and frequent visits to primary care centres.

CONCLUSIONS

The overall prevalence of PIP is 89.6%. PPI is significantly related to certain drugs and patient's conditions. The knowledge of this association is important for the implementation of security measures for medical prescription.

Person-centred care provided by a multidisciplinary primary care team to improve therapeutic adequacy in polymedicated elderly patients (PCMR): randomised controlled trial protocol

INTRODUCTION

The increase in elderly population has led to an associated increase in multiple pathologies, frailty, polypharmacy, healthcare costs, decreased quality of life and mortality. We designed an intervention based on person-centred care model. This article outlines a study protocol, which aims to explore the effects of the intervention to improve therapeutic adequacy in polymedicated elderly patients.

METHODS AND ANALYSIS

An open, randomised, multicentre, controlled clinical trial. The study population includes polymedicated (≥8 prescription medications) patients ≥75 years old. In the intervention group, the multidisciplinary team (primary care pharmacist, family doctor and nurse) will meet to carry out multidimensional reviews (frailty, clinical complexity, morbidity and therapeutic adequacy) of the study subjects. If changes are proposed to the treatment plan, a clinical interview will be conducted with the patient to agree on changes in accordance with their preferences. Follow-up visits will be scheduled at 6 and 12 months. In the control group, where the usual clinical practice will be followed, the necessary data will be collected to compare the results.The key variables are the variation in the mean number of incidents (potentially inappropriate prescription) per patient, the number of medications, the number of changes implemented to the treatment plan and the variation in the number of hospital admissions.

ETHICS AND DISSEMINATION

This study was approved by the Ethics Committee of the IDIAPJGol and by the University of Barcelona's Bioethics Commission. The results are expected to be published in peer reviewed open-access journals, and as part of a doctoral thesis.

CRIDECO Anticholinergic Load Scale: An Updated Anticholinergic Burden Scale. Comparison with the ACB Scale in Spanish Individuals with Subjective Memory Complaints

The increase in life expectancy has also been accompanied by an increase in the use of medication to treat chronic diseases. Polypharmacy is associated with medication-related problems such as the increase in the anticholinergic burden. Older people are more susceptible to anticholinergic effects on the central nervous system and this, in turn, may be related to cognitive impairment. In this paper, we develop an updated anticholinergic burden scale, the CRIDECO Anticholinergic Load Scale (CALS) via a systematic review of the literature and compare it with the currently most used Anticholinergic Burden Scale (ACB). Our new scale includes 217 different drugs with anticholinergic properties, 129 more than the ACB. Given the effect that anticholinergic medications have on cognitive performance, we then used both scales to investigate the relationship between anticholinergic burden and cognitive impairment in adult Spanish subjects with subjective memory complaint. In our population, we observed an association between cognitive impairment and the anticholinergic burden when measured by the new CALS, but not when the ACB was applied. The use of a more comprehensive and upgraded scale will allow better discrimination of the risk associated with the use of anticholinergic medications on cognitive impairment. CALS can help raise awareness among clinicians of the problems associated with the use of medications, or combinations of them, with large anticholinergic effect, and promote a better personalized pharmacological approach for each patient.

[Personal and vaccination history as factors associated with SARS-CoV-2 infection]

BACKGROUND AND OBJECTIVE

SARS-CoV-2 has been and is a major global Public Health challenge. Since the beginning of the pandemic, different comorbidities have been postulated and associated with spectra of increased severity and mortality. The objectives of this research are: 1) to analyse the factors associated with SARS-CoV-2 infection (COVID-19) in a health area in northern Spain; 2) to understand the possible role of influenza vaccination and pneumococcal vaccination in the development of COVID-19.

MATERIALS AND METHOD

A test-negative case-control study was conducted. Variables related to personal and vaccination history were considered. Although the epidemiological definition of the case varied over time, the reference definition was that corresponding to 31/01/2020 in Spain. A bivariate and multivariate analysis was performed.

RESULTS

The sample included 188 patients, of which 63 were cases and 125 controls. The results show that obesity increases the risk 2.4-fold of suffering this infection (IC 95% 1,301-4,521) and ARA-2 increases it 2.2-fold (95% CI 1,256-6,982). On the other hand, anti-pneumococcal vaccination of 13 serotypes showed results close to statistical significance (OR = 0.4; 95% CI 0.170-1,006).

CONCLUSION

Obesity and the use of ARA-2 increases the risk of COVID-19. Scientific knowledge about factors associated with COVID-19 should be expanded. The authors consider that the present research raises the need further investigate the role of vaccines in this infection and their possible heterologous properties.

Combined Multimorbidity and Polypharmacy Patterns in the Elderly: A Cross-Sectional Study in Primary Health Care

(1) Background: The acquisition of multiple chronic diseases, known as multimorbidity, is common in the elderly population, and it is often treated with the simultaneous consumption of several prescription drugs, known as polypharmacy. These two concepts are inherently related and cause an undue burden on the individual. The aim of this study was to identify combined multimorbidity and polypharmacy patterns for the elderly population in Catalonia. (2) Methods: A cross-sectional study using electronic health records from 2012 was conducted. A mapping process was performed linking chronic disease categories to the drug categories indicated for their treatment. A soft clustering technique was then carried out on the final mapped categories. (3) Results: 916,619 individuals were included, with 93.1% meeting the authors’ criteria for multimorbidity and 49.9% for polypharmacy. A seven-cluster solution was identified: one non-specific (Cluster 1) and six specific, corresponding to diabetes (Cluster 2), neurological and musculoskeletal, female dominant (Clusters 3 and 4) and cardiovascular, cerebrovascular and renal diseases (Clusters 5 and 6), and multi-system diseases (Cluster 7). (4) Conclusions: This study utilized a mapping process combined with a soft clustering technique to determine combined patterns of multimorbidity and polypharmacy in the elderly population, identifying overrepresentation in six of the seven clusters with chronic disease and chronic disease-drug categories. These results could be applied to clinical practice guidelines in order to better attend to patient needs. This study can serve as the foundation for future longitudinal regarding relationships between multimorbidity and polypharmacy.

Polypharmacy and the Progression of Chronic Kidney Disease: Korean Cohort Study for Outcome in Patients with Chronic Kidney Disease

INTRODUCTION

The renal hazard of polypharmacy has never been evaluated in predialysis chronic kidney disease (CKD) patients.

OBJECTIVE

We aimed to analyze the renal hazard of polypharmacy in predialysis CKD patients with stage 1-5.

METHOD

The data of 2,238 patients from a large-scale multicenter prospective Korean study (2011-2016), excluding 325 patients with various missing data, were reviewed. Polypharmacy was defined as taking 6 or more medications at the time of enrollment; renal events were defined as a ≥50% decrease in kidney function from baseline values, doubling of the serum creatinine levels, or initiation of renal replacement treatment. Hazard ratio (HR) and 95% confidence interval (CI) were calculated using Cox proportional-hazard regression analysis.

RESULTS

Of the 1,913 patients, the mean estimated glomerular filtration rate was 53.6 mL/min/1.73 m2. The mean medication count was 4.1, and the prevalence of polypharmacy was 27.1%. During the average period of 3.6 years, 520 patients developed renal events (27.2%). Although increased medication counts were associated with increased renal hazard with HR (95% CI) of 1.056 (1.007-1.107, p = 0.025), even after adjusting for various confounders, adding comorbidity score and kidney function nullified the statistical significance. In mediation analysis, 55.6% (p = 0.016) of renal hazard in increased medication counts was mediated by the kidney function, and there was no direct effect of medication counts on renal event development. In subgroup analysis, the renal hazard of the medication counts was evident only in stage 1-3 of CKD patients (p for interaction = 0.014).

CONCLUSIONS

We cannot identify the direct renal hazard of multiple medications, and most of the potential renal hazard was derived from intimate relationship with disease burden and kidney function.

Recommendations on the comprehensive, multidimensional assessment of hospitalized elderly people. Position of the Spanish Society of Internal Medicine

This position paper describes the most relevant and essential aspects of a comprehensive, multidimensional assessment of hospitalized elderly people. The change in demographic patterns and the epidemiological profiles of diseases makes it necessary for internal medicine departments to adapt in order to take into account the vulnerabilities of the elderly in this context. A comprehensive, multidimensional assessment and the multidisciplinary development of a care plan during hospitalization can have an impact in terms of preventing mortality, disability, and institutionalization at discharge. It is necessary for all internists to acquire skills to improve the hospitalization experience in the elderly and obtain better health outcomes in our patients.

Recommendations on the comprehensive, multidimensional assessment of hospitalized elderly people. Position of the Spanish Society of Internal Medicine

This position paper describes the most relevant and essential aspects of a comprehensive, multidimensional assessment of hospitalized elderly people. The change in demographic patterns and the epidemiological profiles of diseases makes it necessary for internal medicine departments to adapt in order to take into account the vulnerabilities of the elderly in this context. A comprehensive, multidimensional assessment and the multidisciplinary development of a care plan during hospitalization can have an impact in terms of preventing mortality, disability, and institutionalization at discharge. It is necessary for all internists to acquire skills to improve the hospitalization experience in the elderly and obtain better health outcomes in our patients.

Nutritional Status of Non-Institutionalized Adults Aged over 65. Study of Weight and Health in Older Adults (PYSMA)

BACKGROUND

A significant increase in the prevalence of malnourishment, obesity, and sarcopenic obesity has been observed in developed countries over the last few decades. In Spain, this especially happens in populations over 65 who are not institutionalized. Differences in lifestyle, medication, and economic capacity partially explain this increase.

OBJECTIVE

To study the nutritional status of a population of 65 year-olds and subjects who are not institutionalized, in the Cádiz region (Spain).

METHODS

Observational, transversal study carried out on 2621 subjects who are 65 years old and over, with a direct weight and height measurement, in 150 pharmacy offices from 44 locations. A mobile application was designed for homogeneous data collection in all the pharmacy offices. The data required from all subjects was gender, age, postal code, social security contribution regime, if the patient lives alone, type of food consumed as the main meals, level of physical activity, polypharmacy, weight, and height.

RESULTS

The prevalence of overweight and obesity amounts to 82.2% of the population (43.2% overweight and 39% obese). We found an inverse relationship between the prevalence of overweight and obesity with carrying out physical activity and having full dinners.

CONCLUSION

We identify the need to reinforce the messages to the elderly aimed at maintaining adequate physical activity and assessing the quality and quantity of dinners, as well as reducing, as much as possible, the treatments that may lead to weight gain.

Polypharmacy and pattern of medication use in community-dwelling older adults: A systematic review

AIM

To synthesise current study findings on the diseases and the corresponding medications that are potentially associated with polypharmacy in community-dwelling older adults.

BACKGROUND

Polypharmacy is receiving increased attention as a potential problem for the older population. Although several scientific investigations have studied polypharmacy, most of them were carried out in long-term care facilities or mixed settings rather than in community settings solely.

METHODS

This systematic review followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Relevant studies published in the English language in peer-reviewed journals were identified from searches of seven electronic databases for the period of January 2000 through December 2019. Inclusion criteria were: (1) Participants were older adults aged 65 years and older; (2) Polypharmacy was defined by medication count; (3) Medication classes associated with polypharmacy were revealed; (4) Studies were conducted in outpatient care or community settings. The Joanna Briggs Institute critical appraisal checklists for cross-sectional studies and for cohort studies were used to assess the methodological quality.

RESULTS

Ten studies were considered having appropriate and acceptable quality to be reviewed, comprising nine cross-sectional studies and one cohort study. Polypharmacy was most defined as concurrently using five or more medications. Polypharmacy prevalence ranged between 7%-45%. Older age, comorbidity, poor self-perceived health status, limitations in physical activity, history of falls, depression, and pain were positively associated with polypharmacy. The most prevalent medication taken by older adults with polypharmacy was cardiovascular drugs.

CONCLUSIONS

The prevalence of polypharmacy in older adults varying widely may be due to geographical locations, clinical practice guidelines, and polypharmacy definition used.

RELEVANCE TO CLINICAL PRACTICE

Validated measurements to investigate medications associated with polypharmacy are required. How polypharmacy develops over time needs to be investigated in longitudinal studies in order to formulate strategies for reducing polypharmacy.

[Prevalence of prescription of anticholinergic/sedative burden drugs among older people with dementia living in nursing homes]

BACKGROUND AND OBJECTIVE

Dementia is one of the most frequent diseases in the elderly, being its prevalence of up to 64% in institutionalized people. In this population, in addition to antidementia drugs, it is common to prescribe drugs with anticholinergic/sedative burden that, due to their adverse effects, could worsen their functionality and cognitive status. The objective is to estimate the prevalence of the use of drugs with anticholinergic/ sedative burden in institutionalized older adults with dementia and to assess the associated factors.

MATERIALS AND METHODS

A cross-sectional study developed in older with dementia living in nursing homes. The prevalence of prescription of anticholinergic/sedative drugs was estimated according to the Drug Burden Index (DBI). A comparative analysis of the DBI score was performed between different types of dementia as well as among various factors and according to the anticholinergic/sedative risk, establishing as a cut-off point of DBI≥1 (high anticholinergic/sedative risk).

RESULTS

178 residents were included. 83.7% had some drug with anticholinergic/sedative burden according to DBI. 50% had a DBI≥1 score. Residents with vascular dementia had a mean DBI of 1.34 (SD 0.84), a significantly higher score than residents with Alzheimer's disease (0.41, 95% CI 0.04-0.78).). Likewise, a higher DBI was associated with more polypharmacy (3.36; 95% CI 2.64-4.08), more falls, hospital admissions and emergency room visits (P<.05).

CONCLUSIONS

Polypharmacy and prescription of anticholinergic/sedative drugs is frequent among institutionalized older adults with dementia, finding an association between DBI, falls and hospital admissions or emergency department visits. Therefore, it is necessary to propose interdisciplinary pharmacotherapeutic optimization strategies.

Social-LCA. Methodological Proposal Applied to Physical Activity Program Implementation into Old People’s Routines

Progressive population aging and life expectancy increase in Spain, resulting from medical and social improvements, have put this population segment in a privileged position for the implementation of new methodologies aimed at improving the quality of life of the elderly. Social life cycle analysis (S-LCA) is a widely studied technique to evaluate the social and environmental impacts generated by a product, service, or process. Throughout this paper, S-LCA is applied to the implementation of physical activity programs in routines for older people, allowing a complete evaluation of the impact of such activities. From this study, it is deduced that the execution phase of the program is the one that causes the most positive impact. Design and programming have a much more notable impact than expected. With regard to the involved categories, the user is the greatest beneficiary of the implementation of these programs, although the local community and administration are other interest groups that will highly benefit, although the impact will be much less than in the case of users.

Multimorbidity patterns in chronic older patients, potentially inappropriate prescribing and adverse drug reactions: protocol of the multicentre prospective cohort study MoPIM

INTRODUCTION

Multimorbidity is a major challenge for current healthcare systems and professionals. From the different approaches that have been proposed to analyse this issue, the hypothesis of the existence of association patterns of different chronic conditions is gaining visibility. In addition, multimorbidity can be associated to polypharmacy, which can lead to a higher risk of potentially inappropriate prescribing (PIP) and consequently to adverse drug reactions (ADRs). The general objective of this novel study is to identify the association between PIP, multimorbidity patterns, polypharmacy and the presence of ADRs in older patients admitted for exacerbation of chronic diseases.

METHODS AND ANALYSIS

The MoPIM (morbidity, potentially inappropriate medication) study is a multicentre prospective cohort study of an estimated sample of 800 older (≥65 years) patients admitted to five general hospitals in Spain due to an exacerbation of a chronic disease. Patients referred to home hospitalisation, admitted due to an acute process or with a fatal outcome expected at the time of admission are excluded. Sociodemographic data, chronic morbidities and geriatric syndromes, number of chronic prescribed medications, PIP at admission to hospital and on discharge, according to the newest screening tool of older screening tool of older person's potentially inappropriate prescriptions/screening tool to alert doctors to right treatment criteria, and ADRs during hospitalisation are being collected. Multimorbidity patterns will be identified using cluster analyses techniques, and the frequency of polypharmacy, PIP and ADRs will be calculated. Finally, the possible relationship between those indicators will be identified through bivariate and multivariate analyses.

ETHICS AND DISSEMINATION

The project has been approved by the clinical research ethics committees of each centre: Comité Ético de investigación Clínica del Parc Taulí, Comitè Ètic d'Investigació Clínica Osona per a la Recerca i Educació Sanitàries (FORES), Comité de Ètica de la Investigación con Medicamentos (CEIm)-Parc de Salut MAR, Comité Ético de Investigación Clínica de Euskadi, Comité de Ética de Investigación del Hospital Universitario de Canarias. The results will be actively and mainly disseminated through publication in peer-reviewed journals and communications in scientific conferences.
