RESUMEN
OBJECTIVE: Aim: The purpose of this study is to report on the development and initial psychometric testing of a questionnaire to investigate nurses' discrimination attitudes and beliefs towards people of dif f erent ethnic origins. PATIENTS AND METHODS: Materials and Methods: The initial stage involved the selection of the questions of the tool after a comprehensive evaluation of the relevant international literature and the tools used in previous related studies. The reliability (forward-backward translation) of the questions was assessed, along with the content, face, and structure. To conduct the study, which was carried out from 07/2021 to 01/2022 a sample consisting of 30 and 2,034 nurses and their assistants was used for the pilot and the fi nal research, respectively. RESULTS: Results: Given that the Kaiser-Meyer-Olkin (KMO) threshold value of 0.89 was achieved, the sample was considered sufficient and appropriate for factor analysis. A statistically signif i cant result (p<0.001) from Bartlett's test indicated a substantial connection between the questions and conf i rmed that the data were suitable for factor analysis. Twenty statements altogether, with seven possible answers ranging from "totally disagree" to "completely agree," were included in the questionnaire. For the questions, three distinct factors - communication, difficulties, and discrimination - were shown to account for 47.1% of the variability. Reliability analyzes showed satisfactory Cronbach alpha coefficient scores for all factors, ranging from 0.78 to 0.82. CONCLUSION: Conclusions: The current study demonstrates that the questionnaire we developed is a legitimate and trustworthy instrument for evaluating professional nurses' discriminatory attitudes and beliefs toward individuals from various ethnic backgrounds. The questionnaire can be used to help design interventions to end discrimination, guarantee equitable access to healthcare services, and provide high-quality care for individuals from diverse backgrounds. It can also be used to identify the factors that inf l uence nurses' attitudes and perceptions toward these patient populations.

BACKGROUND: Wearing facemasks is of proven efficacy as a public health protective measure against COVID-19. Currently there are no observational data concerning the wearing of facemasks and the adherence to guidelines concerning their handling. METHODS: Registration of the way passers-by were wearing facemasks at 26 different locations of five major cities in Greece. The results were correlated with the rate of COVID-19 deaths in the region. RESULTS: In total, 119,433 passers-by were registered, 57,043 females (47.8%) and 62,390 males (52.2%). From the total sample, 81.1% were wearing the mask properly, 10.8% had their nose out, 6.2% were wearing it under the jaw, and 1.9% had no mask at all . There was a significant difference between males and females concerning any use of mask. Inappropriate use of was correlated with COVID-19 death rate in the studied region. CONCLUSION: Our findings suggest that under conditions of mandatory wearing and in central locations of major cities, during walking, proper use of masks is suboptimal, but still contributes with some protection. Fear and risk perception seem to be strong factors contributing to adherence to proper mask wearing.
RESUMEN
INTRODUCTION: The aim of the study was to investigate mental health and conspiracy theory beliefs concerning COVID-19 among health care professionals (HCPs). MATERIAL AND METHODS: During lockdown, an online questionnaire gathered data from 507 HCPs (432 females aged 33.86 ± 8.63 and 75 males aged 39.09 ± 9.54). STATISTICAL ANALYSIS: A post-stratification method to transform the study sample was used; descriptive statistics were calculated. RESULTS: Anxiety and probable depression were increased 1.5-2-fold and were higher in females and nurses. Previous history of depression was the main risk factor. The rates of believing in conspiracy theories concerning the COVID-19 were alarming with the majority of individuals (especially females) following some theory to at least some extend. CONCLUSIONS: The current paper reports high rates of depression, distress and suicidal thoughts in the HCPs during the lockdown, with a high prevalence of beliefs in conspiracy theories. Female gender and previous history of depression acted as risk factors, while the belief in conspiracy theories might act as a protective factor. The results should be considered with caution due to the nature of the data (online survey on a self-selected but stratified sample).

BACKGROUND: This paper attempts to evaluate the primary health care system by evaluating health centres in Greece. METHODS: Malmquist Index Data Envelopment Analysis is applied to study the total productivity of 155 health centres in Greece during 2016-2018. The data were collected from the Ministry of Health and submitted to quality tests to ensure validity and avoid bias. RESULTS: This paper measures the productivity of each of the 155 health centres in Greece and how it shifted during 2016-2018. In addition, the overall productivity change of the 155 health centres over time is calculated and analysed as being due to technical efficiency or technological efficiency. The analysis of the mean values showed a decrease of 0.9% in the overall productivity factor from 2016 to 2017 and a decrease of 5.2% from 2017 to 2018. The overall decrease in the productivity of the 155 health centres was 3.1%. From 2016 to 2018, 59 health centres changed their productivity mainly due to technological change and 91 changed mainly due to technical efficiency change. One health centre showed regression to its total productivity due to equal regression of its technical efficiency and technology. CONCLUSIONS: The method used is nonparametric data envelopment analysis along with the Malmquist index to include panel data in the analysis. Meaningful results were extracted by indicating the number of health centres that improved their productivity, regressed in productivity, or remained constant through the period 2016-2018. This paper may contribute to improving health centres' efficiency and productivity. Furthermore, valuable results can be extracted for the National Health Care System to match available resources that correspond to each health centre's needs, as well as for manager planners and stakeholders in primary health care.
RESUMEN
BACKGROUND: Vein thrombosis (VTE) is a collective term for deep vein thrombosis (DVT) and pulmonary embolism (PE). The aim of this study was to investigate the impact of DVT and its association with health-related quality of life among Greek nurses. METHODS: This is a multicenter descriptive correlation study. The sample of the study was nursing staff working in Greek public hospitals. The diagnosis of DVT was set by Hicks's clinical criteria. RESULTS: The study included 6304 nurses with a mean age of 47.4 ± 4.9 years. Diagnosed by a physician, DVT had 544 (8.6%) participants. The mean score of the overall dimension of physical health-related quality of life was 68.1 ± 21.9 and the overall score of mental health scale was 53.3 ± 10.4. The odds of DVT occurrence increased dramatically for female gender (CI: 27.76, 95% CI: 8.12-94.89, p = 0.001). Increased odds were found also for advanced age (CI: 1.21, 95% CI: 1.09-1.33, p = 0.001), advanced BMI (CI: 1.06, 95% CI: 1.02-1.10, p = 0.001), and smoking (CI: 2.72, 95% CI: 1.51-4.90, p = 0.001). Moreover, previous pregnancy (CI: 1.66, 95% CI: 1.21-2.29, p = 0.002), work experience (CI: 1.13, 95% CI: 1.03-1.23, p = 0.008), and Rhesus (CI: 2.55, 95% CI: 1.11-5.84, p = 0.027) were found to be risk factors for DVT. CONCLUSIONS: Nurses are potentially a professional group for developing deep vein thrombosis, and given the high incidence found in this study, as well as the lower proportion of nurses who were undiagnosed while meeting the clinical criteria of Hick, it is essential for nurses to check their lower extremities for DVT annually.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, all European countries were hit, but mortality rates were heterogenous. The aim of the current paper was to identify factors responsible for this heterogeneity. METHODS: Data concerning 40 countries were gathered, concerning demographics, vulnerability factors and characteristics of the national response. These variables were tested against the rate of deaths per million in each country. The statistical analysis included Person correlation coefficient and Forward Stepwise Linear Regression Analysis (FSLRA). RESULTS: The FSLRA results suggested that 'days since first national death for the implementation of ban of all public events' was the only variable significantly contributing to the final model, explaining 44% of observed variability. DISCUSSION: The current study suggests that the crucial factor for the different death rates because of COVID-19 outbreak was the fast implementation of public events ban. This does not necessarily mean that the other measures were useless, especially since most countries implemented all of them as a 'package'. However, it does imply that this is a possibility and focused research is needed to clarify it, and is in accord with a model of spreading where only a few superspreaders infect large numbers through prolonged exposure.

PURPOSE: The purpose of this paper is to investigate the effect of nurse staffing, nurse education and work experience on patients' length of stay (LOS) in the Greek public hospitals. DESIGN/METHODOLOGY/APPROACH: A cross-sectional study, with retrospective administrative data, was implemented. From all seven Regional Health Authorities of Greece, 25 general surgical units in 17 public hospitals participated in the study. FINDINGS: All over the hospitals were studied, 32,287 patients ⩾17 years old and 203 nursing staff, who were working in the study units, were included in the analysis. According to the multivariate linear regression model, increased years of experience as a nurse (b= -0.04, 95% CI= -0.06 to -0.02, p=0.001) and increased percentage of registered nurse to the total nursing staff (b= -1.18, CI= -1.88 to -0.47, p=0.03) were associated with decreased patient LOS. ORIGINALITY/VALUE: This was the first extended study in Greece, which explored the relationship between nurse staffing, nurse education, work experience and the LOS. The role that nurse staffing play together with its characteristics in the provision toward the quality healthcare services has already been recognized worldwide. The findings revealed the great shortage of nursing staff and the significant correlation between the work experience and educational level to patients' LOS.

AIM: Τranslation and validation of the Kuopio University Hospital Job Satisfaction Scale. BACKGROUND: Nurses' job satisfaction is crucial for the smooth functioning of the health-care system. METHODS: A Greek translation of the scale was made and administered to 126 psychiatric nurses; 60 filled it out again after 15 days. The structural validity and internal consistency of the scale were also studied. Exploratory and confirmatory factor analyses were also conducted. RESULTS: A total of 69 (54.8%) of the participants were male and the majority (72.2%) were <40 years old. The exploratory factor analysis revealed a four-factor scale: Leadership, Working environment, Motivating factors and Team spirit (Cronbach alpha: 0.71-0.88). These factors were not identical to the factors of the Finnish version of the scale. The four-factor model created marginally fits the data and exhibits far better indices. Pearson correlation and intraclass correlation coefficient were near to 1, indicating the scale's high reliability. CONCLUSIONS: The scale's properties were very satisfactory indicating that the scale is a reliable measure of job satisfaction. IMPLICATIONS FOR NURSING MANAGEMENT: The Greek version of the Kuopio University Hospital Job Satisfaction Scale can be recommended to measure nurses' job satisfaction in Cyprus and Greece.

BACKGROUND: The arduous emotional and physical nurses' work, the gradual nursing staff cutbacks and the lack of recognition that nurses feel regarding their skills and overall capabilities are some of the factors that act of bullying between nursing staff and management, between nurses and patients/families or even among nurses themselves. Workplace bullying has physical and psychological effects on worker-victims and, by extension, patients themselves. The purpose of this study was to investigate the relationship between the phenomenon of workplace bullying and general health status among the nursing staff of Greek public hospitals. METHODS: A cross-sectional study was conducted on a convenience sample of 841 members of the nursing staff working in five major hospitals of the 1st Regional Health Authority of Attica, located in Athens. The response rate was 84.1 %. The respondents completed the Negative Acts Questionnaire (NAQ) and the General Health Questionnaire (GHQ-12) and also their demographic characteristics. The appropriate permissions were obtained by the Hospitals' Ethics Committees and the questionnaire's authors. Data were collected from March to July 2013. Data analysis was performed with IBM SPSS 21.0 and included t test, χ (2) test and regression analysis. The two-tailed significance level was set ≤0.05. RESULTS: 30.2 % of the respondents reported that they had been psychologically harassed in their workplaces during the preceding 6 months. Statistical analysis revealed that relative to other respondents, respondents who had received support from their families and friends enjoyed better health but respondents who perceived their work environments more negatively because of work-related bullying suffered from worse general health. CONCLUSIONS: Workplace bullying among nursing staff is a major concern in Greece. Support systems play a crucial role in addressing the negative effects of bullying and they should be taken into account when designing prevention and troubleshooting policies about bullying.
RESUMEN
The aims of this study were to assess haemodialysis nurses' work environment and investigate the correlation between work environment and patients' outcomes. A cross-sectional study was conducted at the 11 public hospital-based haemodialysis units of the 5th Regional Health Authority of Greece. The Practice Environment Scale of the Nursing Work Index (PES-NWI) was used to assess work environment. Nurses were asked to report the frequency of a series adverse events and errors. Study population consisted of 133 nurses (response rate 89.3%). The overall PES-NWI scored just < 2.5 (Mean = 2.48, standard deviation = 0.34) indicating a non-favourable haemodialysis workplace. Nurse-physician Relations, nurse manager ability and nursing foundations for quality of care were the most favourable aspects of work environment. Multivariate logistic regression analysis identified that hypotension (odds ratio (OR) = 0.3, 95% confidence interval (CI) = 0.1-0.9, P = 0.03), venous needle disconnection (OR = 0.14, 95% CI = 0.03-0.65, P = 0.012) and patient fall (OR = 0.02, 95% CI = 0.001-0.51, P = 0.018) were associated with a non-favourable work environment. Findings have important implications for improvement of haemodialysis work environment and enhancement of patients' safety.

In this paper, the overall efficiency of health centers in Greece is measured by applying the input-oriented model of Data Envelopment Analysis. In addition, four different models were subjected to the input-oriented Data Envelopment Analysis to investigate the contribution of each category of human resources to the efficiency results of the health centers. The bootstrap technique was performed to generate confidence intervals for the models. Data for 155 health centers in Greece were provided by the Ministry of Health. The health centers submitted in the analysis obtained an average efficiency value of 0.932. The average results of the partial models in terms of each input show that the efficiency values achieved by the health centers are mostly influenced by the number of physicians and the number of managers employed. The second factor influencing the efficiency values of the health centers are the number of nursing staff occupied in the health centers. Non-medical staff employed in the health centers had the least contribution to the efficiencies measured. This paper provides important information for the stakeholders and the Government of Greece so as to better allocate the personnel employed in primary health care according to the efficiencies attained by the health centers.

INTRODUCTION: Thyroxine is essential for nervous system development. Subclinical hypothyroidism (SCH), also known as mild thyroid failure, is associated with impaired cognitive function in children and mood disorders in adults. Serotonin is also involved in brain development as well as in mood and behavior modulation. The possible interaction between thyroid function tests, serum serotonin concentrations, and emotional intelligence (EI) was studied. METHODS: A total of 224 schoolchildren from the Peloponnese, Greece, aged 11-19, were included in the study, of whom 26.3% had SCH. Emotional quotients (EQ), such as well-being, self-control, emotionality, and sociability, were assessed using the TEIQue-ASF questionnaire, and TSH, fT4, and serum serotonin concentrations were also evaluated. RESULTS: Children and adolescents with SCH had a lower EQ total score (p < 0.001), EQ well-being score (p = 0.025), EQ self-control score (p = 0.029), EQ emotionality score (p = 0.029), and EQ sociability score (p = 0.010) and lower serum serotonin concentrations (p < 0.001). CONCLUSIONS: Children and adolescents with SCH exhibited lower EI scores and lower serum serotonin concentrations when compared with age-matched healthy controls.

Monitoring behavioral and cultural insights during the pandemic is a useful tool to identify factors related to COVID-19 vaccine acceptance and confront the pandemic's vast impact. Data were collected using a questionnaire designed according to the "survey tool and guidance" provided by the World Health Organization (WHO). Surveys were conducted by a market research company for five consecutive months, with a sample of 1000 individuals recruited per survey. Vaccination acceptance increased from 55.2% to 67.2%, while the percentage of undecisive individuals decreased from 16.3% to 10.6%. The proportion of vaccine resistant participants remained relatively steady (25−30%). Knowledge about the pandemic and compliance with preventive measures was high (>90%). Factors associated with vaccination included: Increased age, male gender, influenza vaccination, following authorities' recommendations, being informed by HCWs or formal information sources, care for others, concern about the country's economic recession and health system overload. Pandemic fatigue was reflected across the surveys, indicated by a decrease in the intention to self-isolate and remain at home when ill. Despite the decrease of undecisive individuals, a firm core of vaccine resistant individuals may be responsible for the relatively lower vaccine coverage compared to northern EU countries. Study results could be useful for developing approaches tailored to a reluctant population.

BACKGROUND: Nation-wide SARS-CoV-2 seroprevalence surveys provide valuable insights into the course of the pandemic, including information often not captured by routine surveillance of reported cases. METHODS: A serosurvey of IgG antibodies against SARS-CoV-2 was conducted in Greece between March and December 2020. It was designed as a cross-sectional survey repeated at monthly intervals. The leftover sampling methodology was used and a geographically stratified sampling plan was applied. RESULTS: Of 55,947 serum samples collected, 705 (1.26%) were found positive for anti-SARS-CoV-2 antibodies, with higher seroprevalence (9.09%) observed in December 2020. Highest seropositivity levels were observed in the "0-29" and "30-49" year age groups. Seroprevalence increased with age in the "0-29" age group. Highly populated metropolitan areas were characterized with elevated seroprevalence levels (11.92% in Attica, 12.76% in Thessaloniki) compared to the rest of the country (5.90%). The infection fatality rate (IFR) was estimated at 0.451% (95% CI: 0.382-0.549%) using aggregate data until December 2020, and the ratio of actual to reported cases was 9.59 (7.88-11.33). CONCLUSIONS: The evolution of seroprevalence estimates aligned with the course of the pandemic and varied widely by region and age group. Young and middle-aged adults appeared to be drivers of the pandemic during a severe epidemic wave under strict policy measures.
RESUMEN
A COVID-19 outbreak occurred among residents of a Roma settlement in Greece (8 April-4 June 2020). The aim of this study was to identify factors associated with an increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and to evaluate the effectiveness of control measures implemented. Data were analyzed from individuals that were tested for SARS-CoV-2 during contact tracing, population screening or hospital visits. RT-PCR was used for the detection of SARS-CoV-2 in oropharyngeal samples. Risk factors for household secondary attack rates (SAR) and hospitalization with COVID-19 were examined using chi-square tests, Fisher's exact tests and logistic regression analyses. During the outbreak, 142 cases, 20 hospitalizations and 1 death were recorded, with a total of 2273 individuals tested. The risk of hospitalization was associated with age (OR: 1.04, 95% CI: 1.02-1.07) and Cycle threshold (Ct) values (OR for a decrease in Ct values by 1: 1.18, 95% CI: 1.07-1.31). Household SAR was estimated at 38.62% (95% CI: 32.50-45.01%). After the designation of an isolation facility for cases, household SAR declined from 74.42% to 31.03%. Household size was associated with the risk of infection (OR: 2.65, 95% CI: 1.00-7.07). The presence of COVID-19 symptoms among index cases was correlated with higher transmission (OR: 23.68, 95% CI 2.21-253.74) in multivariate analysis, while age was found to be associated with SAR only in univariate analysis. Roma communities can be particularly vulnerable to the spread of SARS-CoV-2. In similar settings, symptomatic cases are more important transmitters of SARS-CoV-2. Within these communities, immediate measures should be implemented to mitigate disease spread.

A serosurvey of IgG antibodies against SARS-CoV-2 was conducted in Greece between May and August 2020. It was designed as a cross-sectional survey and was repeated at monthly intervals. The leftover sampling methodology was used and a geographically stratified sampling plan was applied. Of 20,110 serum samples collected, 89 (0.44%) were found to be positive for anti-SARS-CoV-2 antibodies, with higher seroprevalence (0.35%) observed in May 2020. The highest seroprevalence was primarily observed in the "30-49" year age group. Females presented higher seroprevalence compared to males in May 2020 (females: 0.58% VS males: 0.10%). This difference reversed during the study period and males presented a higher proportion in August 2020 (females: 0.12% VS males: 0.58%). Differences in the rate of seropositivity between urban areas and the rest of the country were also observed during the study period. The four-month infection fatality rate (IFR) was estimated to be 0.47%, while the respective case fatality rate (CFR) was at 1.89%. Our findings confirm low seroprevalence of COVID-19 in Greece during the study period. The young adults are presented as the most affected age group. The loss of the cumulative effect of seropositivity in a proportion of previous SARS-CoV-2 infections was indicated.
RESUMEN
A Knowledge, Attitudes and Practices (KAP) study was conducted at the end of May 2021 engaging 1456 healthcare workers (HCWs) from 20 hospitals throughout Greece. Acceptance of vaccination against coronavirus disease 2019 (COVID-19) was estimated at 77.7%, with lower vaccine acceptance identified in nurses compared to physicians. Fears related to vaccine safety, lack of information and general knowledge about vaccinations, influenza vaccine acceptance, education level and years of practice were among the factors independently associated with vaccine acceptance. A strong association was identified between vaccination of HCWs in each health region and the population coverage, indicating that HCWs may be role models for the general population. Information campaigns should continue despite decisions taken regarding mandatory vaccinations.

INTRODUCTION: There are only a few published empirical data on COVID-19's effects on the mental health. MATERIAL AND METHODS: During lockdown, an online questionnaire registered demographic, health data, previous psychiatric history, current anxiety, depression and suicidality, believing in conspiracy theories and other domains. Data from 3399 persons were used (81.08% females; aged 34.02 ± 9.72 and 18.27% males; aged 36.38±10.33). Distress and clinical depression were identified with the use of cut-off and a previously developed algorithm respectively. STATISTICAL ANALYSIS: A post-stratification method was used; descriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses and Factorial Analysis of Variance (ANOVA) tested relations among variables. RESULTS: Clinical depression was present in 9.31% of the stratified sample, while 8.5% had severe distress; increased anxiety was present in more than 45%. Suicidal thoughts increased in 10.40% and decreased in 4.42%. Beliefs in conspiracy theories were widely prevalent; at least half of cases were following various misconceptions. A model for the development of depression was created with general health status, previous history of depression, self-harm and suicidal attempts, family responsibility, economic change, and age acting as risk factors, while keeping a daily routine, pursuing religiousness/spirituality, and believing in conspiracy theories acting as protective factors. CONCLUSIONS: The model developed here revealed multiple vulnerabilities and an interplay leading from simple anxiety to clinical depression and suicidality through distress. This could be of practical utility since most of these factors are modifiable. Future research, as well as interventions, should focus specifically on them.

The novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread rapidly during the first months of 2020 and continues to expand in multiple areas across the globe. Molecular epidemiology has provided an added value to traditional public health tools by identifying SARS-CoV-2 clusters or providing evidence that clusters based on virus sequences and contact tracing are highly concordant. Our aim was to infer the levels of virus importation and to estimate the impact of public health measures related to travel restrictions to local transmission in Greece. Our phylogenetic and phylogeographic analyses included 389 full-genome SARS-CoV-2 sequences collected during the first 7 months of the pandemic in Greece and a random collection in five replicates of 3,000 sequences sampled globally, as well as the best hits to our data set identified by BLAST. Phylogenetic trees were reconstructed by the maximum likelihood method, and the putative source of SARS-CoV-2 infections was inferred by phylogeographic analysis. Phylogenetic analyses revealed the presence of 89 genetically distinct viruses identified as independent introductions into Greece. The proportion of imported strains was 41%, 11.5%, and 8.8% during the three periods of sampling, namely, March (no travel restrictions), April to June (strict travel restrictions), and July to September (lifting of travel restrictions based on thorough risk assessment), respectively. The results of phylogeographic analysis were confirmed by a Bayesian approach. Our findings reveal low levels of onward transmission from imported cases during summer and underscore the importance of targeted public health measures that can increase the safety of international travel during a pandemic. IMPORTANCE Our study based on current state-of-the-art molecular epidemiology methods suggests that virus screening and public health measures after the lifting of travel restrictions prevented SARS-CoV-2 onward transmission from imported cases during summer 2020 in Greece. These findings provide important data on the efficacy of targeted public health measures and have important implications regarding the safety of international travel during a pandemic. Our results can provide a roadmap about prevention policy in the future regarding the reopening of borders in the presence of differences in vaccination coverage, the circulation of the virus, and the presence of newly emergent variants across the globe.
