Emotional intelligence is more important than the learning environment in improving critical thinking.

PURPOSE: To examine the association of critical thinking (CT) and emotional intelligence (EI) versus CT and learning environment (LE) in order to investigate which has the greatest influence EI or LE. MATERIALS AND METHODS: A cross-sectional study was conducted with 340 s-year healthcare university students in two nursing and one medical schools from three universities in Greece, between October and December 2020. Critical Thinking Disposition Scale, Dundee Ready Education Environment Measure, and Trait Emotional Intelligence Questionnaire-Short Form were administered. Hierarchical multiple linear regression analysis, with five steps, was used to compare the associations of CT and EI to CT and LE. RESULTS: Participants' mean age (years) was 20.9 (6.6 SD); 82.6% female; 86.8% studying nursing. Students mean scores were moderate to high for CT disposition (44.7 ± 4.68). The general characteristics (age, gender, and school) were not significantly associated with CT (p > 0.05). However, CT was positively associated with LE (UCB = 0.064 & p < 0.001) and EI (UCB = 1.522 & p < 0.001). Moreover, CT seems to be associated in a higher degree (R2 change adj = 0.036 & p < 0.001) with emotional intelligence (UCB = 1.522) than with learning environment (UCB = 0.064). CONCLUSIONS: Our findings suggest a different more optimal pathway for educators to improve the CT of their students through EI and not with LE as believed till now. By focusing on improving EI, educators may help their students become critical thinkers, who will provide better quality of care.

The COVID-19 burnout scale: development and initial validation.

BACKGROUND: Research on the pandemic-related burnout has focused on work-related burnout especially among healthcare workers, but not in the general population. AIM: To develop a valid and reliable instrument scale to measure pandemic-related burnout in the general population. METHODS: We took several steps to develop the scale items and achieve content and face validity; literature review, panel of experts, calculation of content validity ratio, and cognitive interviews. We assessed structural and construct validity, and reliability of the COVID-19 burnout scale (COVID-19-BS). RESULTS: Exploratory and confirmatory factor analysis identified three factors for the COVID-19-BS; emotional exhaustion, physical exhaustion, and exhaustion due to measures against the COVID-19. Cronbach's alpha coefficients for the three factors and the COVID-19-BS ranged from 0.860 to 0.921. Kaiser-Meyer-Olkin value was 0.945, and p-value for Bartlett test was <0.001. A significant positive correlation between the three factors and anxiety and depression indicated high concurrent validity. Cohen's kappa ranged from 0.848 to 0.957, while intraclass correlation coefficients ranged from 0.888 to 0.997. CONCLUSIONS: Our findings indicate that the final 3-factor model with 13 items of COVID-19-BS is a brief, easy to administer, valid and reliable scale for assessing COVID-19-related burnout in the general public.

Postgraduate education in healthy and active ageing: a systematic scoping review of learning needs, curricula and learning impact.

To inform a new European-based online master's programme in active aging and age-friendly society, a scoping review was performed to identify previously reported learning needs and learning outcomes on this topic. Four electronic databases (PubMed, EBSCO [Academic Search Complete], Scopus, and ASSIA) were systematically searched, along with gray literature. Dual, independent review of an initial 888 studies led to 33 included papers which underwent independent data extraction and reconciliation. Just 18.2% of studies employed a student survey or similar to determine learning needs, with the majority reporting educational intervention objectives, learning outcomes or curriculum content. Main study topics were intergenerational learning (36.4%), age-related design (27.3%), health (21.2%), attitudes toward aging (6.1%), and collaborative learning (6.1%). This review found limited literature on student learning needs in healthy and active aging. Future research should elucidate student- and other stakeholder-determined learning needs, with robust evaluation of post-education skills, attitudes, and practice change.

Learning needs in healthy and active aging according to key stakeholders: a multinational survey.

Healthy and active aging and age-friendly society frameworks attempt to address the well-documented challenges and opportunities of population aging. To meet the needs of an increasingly older society, there is a demand for professionals with appropriate age-related knowledge and skills. To this end, a master's in active aging is in development. This study reports on the consultation with prospective students, employers, older people and academics on the knowledge areas to be included in the course. An anonymous online survey gathered data from stakeholders in Ireland, Slovenia, Austria, Portugal, Finland, and Greece. Participants ranked the importance of 14 broad knowledge areas and linked topics. The influence of participant characteristics on decisions was examined using multivariate regression modeling. Across all stakeholder groups (total sample N = 757), health promotion was most often deemed very important (80%), followed by psychology (73%), and social inclusion and engagement (71%). Potential students from healthcare backgrounds were more interested than others in aging physiology, social aspects, and the physical environment. More western-located European countries overall showed more enthusiasm for the topics presented, additional to regional variations between topics. This learning needs analysis provides multi-stakeholder insights into priorities regarding learning in healthy and active aging and age-friendly society.

Exploration of the relationship between stigma and burnout among Greek nurses in dementia care.

OBJECTIVE: To investigate possible correlations between stigma and burnout of nurses and non-graduate professional caregivers of elderly with dementia in nursing homes. BACKGROUND: Research on dementia stigma in health care professionals as well as its relationship with their well-being is seriously lacking. METHODS: This cross-sectional study involved a convenience sample of 171 nurses and other professional caregivers in 16 Greek elderly care units who responded to Maslah Burnout Inventory (ΜΒΙ) as well as the Family Stigma in Alzheimer's Disease Scale (FS-ADS). In order to find adjusted associations between independent variables and the stigma and burnout of professional caregivers, multiple linear regression analysis was used. RESULTS: Cognitive, emotional and behavioural attributions of the three dimensions of stigma were found to be independent predictive factors of burnout's dimensions which indicate that stigma nurses deposit on patients, contributes towards their burnout. CONCLUSION: Educational preparation of geriatric nurses should provide them with the option of seeing dementia as a normal stage of life since reducing stigma can contribute towards preventing and managing professional burnout. IMPLICATIONS FOR NURSING MANAGEMENT: In order to reduce burnout, nurse managers should design lifelong learning programs on the basis of changing the stigmatizing negative cognitive and emotional attitudes of professionals towards dementia.

Is aircraft noise exposure associated with cardiovascular disease and hypertension? Results from a cohort study in Athens, Greece.

BACKGROUND: We followed up, in 2013, the subjects who lived near the Athens International Airport and had participated in the cross-sectional multicountry HYENA study in 2004-2006. OBJECTIVE: To evaluate the association of exposure to aircraft and road traffic noise with the incidence of hypertension and other cardiovascular outcomes. METHODS: From the 780 individuals who participated in the cross-sectional study, 537 were still living in the same area and 420 accepted to participate in the follow-up. Aircraft and road traffic noise exposure was based on the estimations conducted in 2004-2006, linking geocoded residential addresses of the participants to noise levels. We applied multiple logistic regression and Cox proportional hazards models, adjusting for potential confounders. RESULTS: The incidence of hypertension was significantly associated with higher aircraft noise exposure during the night. Specifically, the OR for hypertension per 10 dB increase in Lnight aircraft noise exposure was 2.63 (95% CI 1.21 to 5.71). Doctor-diagnosed cardiac arrhythmia was significantly associated with Lnight aircraft noise exposure, when prevalent and incident cases were considered with an OR of 2.09 (95% CI 1.07 to 4.08). Stroke risk was also increased with increasing noise exposure but the association was not significant. Twenty-four-hour road traffic noise associations with the outcomes considered were weaker and less consistent. CONCLUSIONS: In conclusion, our cohort study suggests that long-term exposure to aircraft noise, particularly during the night, is associated with incident hypertension and possibly, also, cardiovascular effects.

Attitudes towards people with physical or intellectual disabilities among nursing, social work and medical students.

AIMS AND OBJECTIVES: To examine and compare undergraduate healthcare students' attitudes towards people with physical or intellectual disabilities in Greece. BACKGROUND: The experience that people with disabilities have with health care is a complex interaction between their medical condition and the social and physical environment. Attitudes of the nursing and healthcare staff affect the quality of care and people's adaptation to their disability, self-image and rehabilitation outcomes. DESIGN: Descriptive cross-sectional survey. METHODS: Nursing, Social Work and Medicine students (N = 1007, 79.4% female) attending three universities (Athens, Crete) completed during 2014-2016 two standardised scales regarding physical (ATDP-B) and intellectual disability (CLAS-ID). Descriptive and multivariate logistic regression analyses were performed. RESULTS: Attitudes towards people with physical disabilities in Greece (ATDP-B scores) were poor with scores just above the mid-point. Medical studies and higher knowledge and work with individuals with physical disabilities signified marginally more positive attitudes. Gender and age displayed no associations with attitudes. Regarding intellectual disability (CLAS-ID scores), nursing students had slightly less positive attitudes in "Similarity" but more positive attitudes in "Sheltering" subscales. Previous work and contact was related to more favourable and higher age to less favourable "Similarity" and "Sheltering" attitudes. Males had higher "Exclusion" scores. Those who knew people with intellectual disabilities had less favourable "Empowerment" attitudes. Knowledge was related to more positive attitudes in all four CLAS-ID subscales. CONCLUSIONS: Greek health and social care students showed poor attitudes towards people with physical and intellectual disability. RELEVANCE TO CLINICAL PRACTICE: When holding unfavourable attitudes, healthcare professionals become less involved with the people they care for and they do not provide nursing care to the best of their abilities. Undergraduate and continuing education, along with workplace enhancements, should aim to provide high-quality health care to people with disabilities.

The quality of recovery on discharge from hospital, a comparison between patients undergoing hip and knee replacement - a European study.

AIMS AND OBJECTIVES: To describe and compare the quality of recovery on discharge from hospital among patients undergoing elective hip or knee replacement. The study will also attempt to identify any predicting factors. BACKGROUND: Arthroplasty is commonly used for an increasing population of patients with osteoarthritis, and the recovery process starts directly after surgery. Today's shorter hospital stay may be a challenge for the patients during the early period of recovery. It is therefore important to identify factors associated with quality of recovery at discharge from hospital. DESIGN: A descriptive, comparative study including 12 hospitals in 5 European countries; Cyprus, Finland, Greece, Iceland and Sweden. METHODS: Consecutively included patients responded on: health-related quality of life, and emotions before surgery and at hospital discharge; quality of recovery, patient satisfaction and fulfilment of knowledge expectations. Related factors and associations were analysed separately for each kind of arthroplasty. In total, 865 patients were included (hip n = 413, knee n = 452). RESULTS: In the dimension of pain, patients undergoing hip replacement had significantly better quality of recovery compared to those undergoing knee replacement. Both patient groups experienced negative emotions before surgery that were related to poorer quality of recovery. Fulfilment of knowledge expectations has a limited effect on quality of recovery. Greater satisfaction with care predicted better quality of recovery. CONCLUSIONS: Negative preoperative emotions were related to poorer quality of recovery. For both kinds of arthroplasty, greater satisfaction with care was associated with better quality of recovery. RELEVANCE TO CLINICAL PRACTICE: The result emphasises the need to detect patients in need of support in their preparation and recovery process, taking into account the perspective of their emotional state.

Patient participation in hospital care: Nursing staffs' point of view.

The aim was to investigate nursing staff's perceptions related to patient participation and the parameters affecting it during nursing care. A cross-sectional study with both a quantitative and qualitative orientation was conducted. The sample consisted of all nursing staff working in medical and surgical wards in three Greek hospitals. A questionnaire was developed and the data were analysed with exploratory factor analysis, whereas content analysis was used for qualitative data. Nursing staff perceived participation as the process of information giving to patients, communication of symptoms by patients and compliance with the staff's orders. 'Information providing' and 'ability to influence and responsibility' were significant aspects of the content of participation, whereas the parameters affecting participation were related to patients, nursing staff and the care context. These results support patient engagement in dialogue and shared decision-making, while highlighting the need to implement participation systematically and stimulate changes in nursing care organization.

Fulfilment of knowledge expectations among family members of patients undergoing arthroplasty: a European perspective.

In the recovery process of arthroplasty patients, their family members play an important role due to short hospital stay and increased age of patients. Family members need to have knowledge to be able to support the patient. The aim of this study was to explore expected and received knowledge in family members of arthroplasty patients and describe the relationships between the differences in received and expected knowledge and background factors, country, information and control preferences and access to knowledge. The study was conducted in six European countries (Cyprus, Greece, Finland, Iceland, Spain and Sweden). The study design was cross-cultural, prospective and comparative with two measurement points: pre-operative and at discharge from hospital. Knowledge Expectations of significant other-scale and Krantz Health Opinion Survey were used before surgery and Received Knowledge of significant other-scale and Access to Knowledge at discharge. Patients undergoing elective hip or knee arthroplasty in seventeen hospitals were asked to identify one family member. The sample size was decided by power calculation. A total of 615 participants answered the questionnaires at both measurements. Family members perceived to receive less knowledge than they expected to have, most unfulfilled knowledge expectations were in the financial, social and experiential dimensions of knowledge. Seventy-four per cent of participants had unfulfilled knowledge expectations. Increased access to information from healthcare providers decreased the difference between received and expected knowledge. Compared to family members in southern Europe, those in the Nordic countries had more unfulfilled knowledge expectations and less access to information from healthcare providers. The evidence from this study highlights the need to involve the family members in the educational approach.

Knowledge expectations of surgical orthopaedic patients: a European survey.

Ageing population entails a growing international problem of osteoarthritis. Best practices for education of these patients are lacking. This study focused on empowering education in Northern (Finland, Iceland, Lithuania and Sweden) and Southern Europe (Cyprus, Greece and Spain). The aim was to analyse associations between expected knowledge and background factors. The data were collected from European arthroplasty patients with the Knowledge Expectations of hospital patients- scale, (KE(hp) - scale), including bio-physiological, functional, experiential, ethical, social and financial dimensions. Patients had essential bio-physiological and functional knowledge expectations. Women expected more than men, employed less than retired, unemployed or who worked at home. Generally, patients in Northern countries expected more than in Southern countries. However, highest expectations were found in Sweden and Greece, lowest in Spain and Cyprus. There are differences in knowledge expectations based on patients' backgrounds. Development of common standards in European patient education needs further research.

Exploration and classification of intensive care nurses' clinical decisions: a Greek perspective.

AIM: The recording, identification, coding and classification of clinical decisions by intensive care nurses. BACKGROUND: Clinical decision-making is an essential dimension of nursing practice as through this process nurses make choices to meet the goals of patient care. Intensive care nurses' decision-making has received attention because of the complexity and urgency associated with it, however, the types of nurses' clinical decisions have not been described systematically. METHODS: Qualitative content analysis of daily diaries of clinical decisions recorded during nursing work by 23 purposefully selected intensive care nurses from three major hospitals of Greece. The process of data collection and analysis continued until the point of theoretical saturation. FINDINGS: Eight categories of nursing clinical decisions emerged including decisions related to: (1) evaluation, (2) diagnosis, (3) prevention, (4) intervention, (5) communication with patients, (6) clinical information seeking, (7) setting of clinical priorities and (8) communication with health care professionals. Psychological assessment and support decisions were scarce, whereas patient input in care decisions appeared to be limited. The most frequent types of decisions were regarding intervention (29%), evaluation (25%) and clinical setting of priorities (17%), while clinical information seeking (3%) and communication with patients decisions (2%) were the least frequent. Additionally, recorded decisions were ranked in order of degree of urgency and of dependency on medical order. Non-urgent decisions were 78% of the total and 60% of nurses' intervention decisions were independent of medical order and were related to basic nursing care. CONCLUSIONS: Intensive care nurses make multiple decisions that seem to be in line with the nursing process, although the latter is not officially implemented in Greek ICUs. RELEVANCE TO CLINICAL PRACTICE: The types and frequency of clinical decisions made by intensive care nurses are related to features of ICU work environment, their professional autonomy and accountability, as well as their perceptions of their clinical role.

Impact of workplace bullying on job burnout and turnover intention among nursing staff in Greece: Evidence after the COVID-19 pandemic.

Introduction: The prevalence of workplace bullying, job burnout, and turnover intention among nursing staff increased during the COVID-19 pandemic. However, to the best of our knowledge, there are no studies that have measured the relationships among variables of interest after the pandemic. Objective: Our intention is to investigate the effect of workplace bullying on job burnout and turnover intention in nursing staff. Methods: We conducted a cross-sectional study during January-February 2024 in Greece. We obtained a convenience sample of 450 nurses. We used the 22-item Negative Acts Questionnaire-Revised to assess workplace bullying. We measured job burnout with the single-item burnout measure. We measured nurses' turnover intention with a valid 6-point Likert scale. Results: The study sample included 450 nurses with the mean age of 39.1 years (standard deviation [SD] = 10.2). The mean workplace bullying score was 7.7 (SD = 2.0), while the mean job burnout score was 7.7 (SD = 2.0). Among our nurses, 57.3% showed a high level of turnover intention. After eliminating confounders, we found that increased workplace bullying (adjusted beta = 0.031, 95% confidence interval [CI] = 0.023 to 0.039, p < 0.001) was associated with increased job burnout. Moreover, multivariable logistic regression analysis showed that increased turnover intention was more common among nurses who experienced higher levels of workplace bullying (adjusted odds ratio = 1.057, 95% CI = 1.043 to 1.071, p < 0.001). Conclusion: We found a positive relationship between workplace bullying, job burnout, and turnover intention. Nurse managers, organizations, and policy-makers ought to consider such findings to intervene and decrease workplace bullying by improving working conditions.

Evaluating Critical Thinking Disposition, Emotional Intelligence, and Learning Environment of Nursing Students: A Longitudinal Study.

BACKGROUND: The COVID-19 pandemic may have inhibited the development of critical thinking and emotional intelligence of nursing students due to the transition from traditional to online learning environments. OBJECTIVE: The objective was to evaluate the development of critical thinking, emotional intelligence, and the perceived learning environment of nursing students during the pandemic from their first to second year. METHODS: This was a longitudinal study of 82 nursing students from 2 universities in Greece. We measured critical thinking disposition, emotional intelligence, and the students' perceptions of the learning environment in 2 phases, separated by a 10 month interval, before and during the pandemic. RESULTS: Students had moderate-to-high critical thinking and emotional intelligence and perceived the learning environment as more positive than negative in both phases. However, there were no statistically significant changes between phases in critical thinking disposition (mean score 44.3 vs 45.1, p = .224) and emotional intelligence (mean score 5.05 vs 5.06, p = .950) between the 2 phases. Nevertheless, students rated the online learning environment (phase 2) higher than the traditional (mean score 137.8 vs 132.2, p = .005). CONCLUSIONS: Critical thinking and emotional intelligence did not change, but students favored the online learning environment over the traditional. These findings suggest that nurse educators persevered, adapted, and maintained the quality of the learning environment despite the pandemic. Moreover, the utilization of an online learning environment may have led to enhanced enjoyment and engagement for students, which could potentially result in improved learning outcomes.

Predictors of Seasonal Influenza Vaccination Willingness among High-Risk Populations Three Years after the Onset of the COVID-19 Pandemic.

High-risk populations are at increased risk of severe influenza-related illness, hospitalization, and death due to influenza. The aim of our study was to assess the willingness of high-risk populations to take the influenza vaccine for the 2022-2023 season, and to investigate the factors associated with such willingness. We conducted a cross-sectional study in Greece in September 2022 using a convenience sample. We considered demographic characteristics, COVID-19-related variables, resilience, social support, anxiety, depression, and COVID-19-related burnout as potential predictors. Among participants, 39.4% were willing to accept the seasonal influenza vaccine, 33.9% were unwilling, and 26.8% were hesitant. Multivariable analysis identified that increased age and increased family support were associated with increased influenza vaccination willingness. Moreover, participants that have received COVID-19 booster doses were more willing to accept the influenza vaccine. In contrast, adverse effects because of COVID-19 vaccination and exhaustion due to measures against COVID-19 reduced influenza vaccination willingness. We found that the intention of high-risk populations to receive the influenza vaccine was low. Our study contributes to an increased understanding of the factors that affect vaccination willingness. Public health authorities could use this information to update vaccination programs against influenza. Emphasis should be given on safety and effectiveness issues.

Linking Learning Environment and Critical Thinking through Emotional Intelligence: A Cross-Sectional Study of Health Sciences Students.

BACKGROUND: Health sciences educators should increase the critical thinking of their students as this may improve the quality of care. However, this is rarely considered as a critical point in teaching, despite studies identifying factors such as the learning environment and emotional intelligence as increasing critical thinking at an undergraduate level. Thus, there is a need to better explore these factors and investigate interrelations and ways of improving critical thinking, especially in the critical field of healthcare students (nursing and medicine). OBJECTIVES: The present study aimed to examine the potential relationships between critical thinking with emotional intelligence and the learning environment. METHOD: This was a descriptive cross-sectional study with 208 first year health sciences university students of two nursing departments and one medicine department from three universities in Greece. The Critical Thinking Disposition Scale, Dundee Ready Education Environment Measure, and Trait Emotional Intelligence-Short Form questionnaires were used to assess critical thinking, the education environment, and emotional intelligence, respectively. RESULTS: The results demonstrate that critical thinking was positively related to emotional intelligence (ß = 0.82, p < 0.001), but not to the learning environment (ß = 1.06, p = 0.30). However, a structural equation modeling analysis supported the indirect relationship between the learning environment and critical thinking through emotional intelligence (M = 1.10, CI = 0.13-2.17, p < 0.05). CONCLUSIONS: Emotional intelligence may be the underlying mechanism for achieving critical thinking if it is well applied and cultivated in a learning environment. Therefore, universities could modify their curricula and place emotional intelligence at the epicenter of teaching.

The Cost and the Value of Stroke Care in Greece: Results from the SUN4P Study.

The aim of this study was to measure the one-year total cost of strokes and to investigate the value of stroke care, defined as cost per QALY. The study population included 892 patients with first-ever acute strokes, hemorrhagic strokes, and ischemic strokes, (ICD-10 codes: I61, I63, and I64) admitted within 48 h of symptoms onset to nine public hospitals located in six cities. We conducted a bottom-up cost analysis from the societal point of view. All cost components including direct medical costs, productivity losses due to morbidity and mortality, and informal care costs were considered. We used an annual time horizon, including all costs for 2021, irrespective of the time of disease onset. The average cost (direct and indirect) was extrapolated in order to estimate the national annual burden associated with stroke. We estimated the total cost of stroke in Greece at EUR 343.1 mil. a year in 2021, (EUR 10,722/patient or EUR 23,308 per QALY). Out of EUR 343.1 mil., 53.3% (EUR 182.9 mil.) consisted of direct healthcare costs, representing 1.1% of current health expenditure in 2021. Overall, productivity losses were calculated at EUR 160.2 mil. The mean productivity losses were estimated to be 116 work days with 55.1 days lost due to premature retirement and absenteeism from work, 18.5 days lost due to mortality, and 42.4 days lost due to informal caregiving by family members. This study highlights the burden of stroke and underlines the need for stakeholders and policymakers to re-organize stroke care and promote interventions that have been proven cost-effective.

Exposure modifiers of the relationships of transportation noise with high blood pressure and noise annoyance.

In the cross-sectional hypertension and exposure to noise near airports study the relationship between road traffic noise, aircraft noise and hypertension and annoyance was investigated. The data collection comprised a variety of potentially exposure modifying factors, including type of housing, location of rooms, window opening habits, use of noise-reducing remedies, shielding due to obstacles, lengths of exposure. In the present paper the quantitative role of these factors on the relationship between road and aircraft noise exposure and outcomes was analyzed. Multiple logistic and linear regression models were calculated including these co-factors and related interaction terms with noise indicators, as well as stratified analyses. Type of housing, length of residence, location of rooms and the use of noise reducing remedies modified the relationship between noise and hypertension. However, the effects were not always in the direction of a stronger association in higher exposed subjects. Regarding annoyance, type of housing, location of rooms, noise barriers, window opening habits, noise insulation, the use of noise reducing remedies, hours spent at home during daytime were significant effect modifiers. The use of noise-reducing remedies turned out to be indicators of perceived noise disturbance rather than modifiers reducing the annoyance.

Sarcopenia and polypharmacy among older adults: A scoping review of the literature.

BACKGROUND: Sarcopenia and polypharmacy are both prevalent conditions in the geriatric population, leading to poor quality of life and adverse outcomes. OBJECTIVE: To explore the evidence on the relationship between sarcopenia and polypharmacy and to summarize the findings and the gaps from the existing literature. METHOD: A systematic scoping review was conducted between March and May 2021, with no restriction on publication date, using the Arksey and O'Malley framework and reported according to PRISMA-ScR. Four bibliographic databases, PubMed, Web of Science, Scopus, Proquest One Academic, and four sources of gray literature were searched for studies written in English or Greek. Data were extracted quantitatively and using thematic analysis. RESULTS: Of the 397 initially retrieved records, 22 studies were finally included in this review, 20 published articles and 2 posters-presentations. Most of the studies used cross-sectional data. The relationship between sarcopenia and polypharmacy should be interpreted on the basis of the definition of polypharmacy, the diagnostic criteria of sarcopenia used, and the population setting. Sarcopenia or risk for sarcopenia are associated with polypharmacy or the number of medications in community-dwelling older adults, regardless of diagnostic criteria used for sarcopenia. CONCLUSION: There is an association between sarcopenia or risk for sarcopenia and polypharmacy or the number of medications in community-dwelling older adults but not among residents of nursing homes or inpatients. Specific widely accepted definitions of polypharmacy and sarcopenia, a consensus on the method of sarcopenia assessment, and prospective studies are needed to identify polypharmacy as a potential risk factor for sarcopenia.

Social Support Mediates the Relationship between COVID-19-Related Burnout and Booster Vaccination Willingness among Fully Vaccinated Nurses.

COVID-19 booster doses for high-risk groups such as nurses are necessary to reduce the impacts of the pandemic and promote public health. We examined the relationship between COVID-19-related burnout and booster vaccination willingness among nurses, and we assessed whether social support can buffer this relationship. We conducted a cross-sectional study with 963 fully vaccinated nurses working in healthcare settings in Greece. We used the multidimensional scale of perceived social support to measure social support and the COVID-19 burnout scale to measure COVID-19-related burnout. We measured vaccination willingness with a scale from 0 (extremely unlikely to take a booster dose) to 10 (extremely likely). Among nurses, 37.1% reported being very likely to be vaccinated, 34.4% reported being uncertain about their likelihood of vaccination, and 28.6% reported being very unlikely to be vaccinated with a booster dose. We found that COVID-19-related burnout reduced vaccination willingness, while social support functioned as a partial mediator of this relationship. In conclusion, nurses who experienced burnout were less likely to accept a booster dose. Furthermore, increasing nurses' social support reduced the negative effects of burnout, resulting in improved booster vaccination willingness. Immunization awareness programs should be implemented in order to address nurses' concerns and support booster doses.
