Perceptions of Teamwork and Knowledge Attitudes of Hemodialysis Unit Nurses on Infection Prevention.

INTRODUCTION: The Nurses of Hemodialysis Units: it is necessary to face HAIs (hospital-acquired infections) as a "well-tuned" teamwork. The aim of this study was to investigate the perceptions of the teamwork as well as the knowledge attitudes of the nurses of hemodialysis units on infection prevention in Greece. METHODOLOGY: A cross-sectional survey was conducted with a sample of 1018 HCWs (health care workers) of hemodialysis units in Greece. The questionnaires used were: Teamwork Perceptions Questionnaire (T-TPQ) TeamSTEPPS®-Instructor Manual, and questionnaire APPENDIX A. RESULTS: The majority of them were nurses (69.45%) and nurse assistants (23.87%). About teamwork perceptions per factor, we observed uniformity in their responses with very high rates of agreement. The attitudes of nurses of hemodialysis units on the prevention of infections were distinguished in particularly high rates of compliance with a high perception of the risk of transmission of infections with better compliance being that of women. Also, women seem to be more knowledgeable about diseases that mostly affect the pediatric population. It seemed that level of knowledge between the two sexes did not differ regarding HBV (63.16% vs. 66.71%, p = 0.430), HCV (63.91% vs. 66.71%, p = 0.553), HIV infection (78.95% vs. 81.76%, p = 0.471), and influenza (55.64% vs. 59.61%, p = 0.394). CONCLUSIONS: This study highlighted for the first time the high level of perceptions of teamwork of the HCWs of the hemodialysis units in Greece. It is recommended to investigate the correct application of prevention measures and to detect the causes of deviation from good practices with subsequent investigations on hemodialysis units of Greece.

Estimation of the determinants for HIV late presentation using the traditional definition and molecular clock-inferred dates: Evidence that older age, heterosexual risk group and more recent diagnosis are prognostic factors.

OBJECTIVES: HIV late presentation (LP) has been increasing in recent years in Europe. Our aim was to investigate the characteristics of LP in Greece using in addition to the traditional definition for LP, the time interval between HIV infection and diagnosis. METHODS: Our nationwide sample included HIV-1 sequences generated from 6166 people living with HIV (PLWH) in Greece during the period 1999-2015. Our analysis was based on the molecularly inferred HIV-1 infection dates for PLWH infected within local molecular transmission clusters of subtypes A1 and B. RESULTS: Analysis of the determinants of LP was conducted using either CD4 counts or AIDS-defining condition at diagnosis or the time from infection to diagnosis. Older age, heterosexual transmission risk group and more recent diagnosis were associated with increased risk for LP. In contrast to previous studies, people who inject drugs (PWID) had a shorter median time to diagnosis (0.63 years) compared to men who have sex with men (MSM) (1.72 years) and heterosexuals (2.43 years). Using HIV infection dates that provide an unbiased marker for LP compared to CD4 counts at diagnosis, which are age-dependent, we estimated that the time to diagnosis increased gradually with age. Migrants infected regionally do not differ with respect to LP status compared to native Greeks. CONCLUSIONS: We demonstrate that older people and heterosexuals are among those at higher risk for LP; and given the growing number of older people among newly diagnosed cases, tailored interventions are needed in these populations.

Depression, Insomnia and Post-Traumatic Stress Disorder in COVID-19 Survivors: Role of Gender and Impact on Quality of Life.

Evidence to date suggests that a significant proportion of COVID-19 patients experience adverse psychological outcomes and neuropsychiatric complications. The aim of this study was to evaluate the effect of SARS-CoV-2 infection and subsequent hospitalization on the mental health, sleep, and quality of life of COVID-19 survivors. Patients were assessed 1−2 months after hospital discharge using standardized screening tools for depression and anxiety (HADS), post-traumatic stress disorder (IES-R), insomnia (AIS), and quality of life (EQ-5D-5L). Sociodemographic factors, comorbidities, disease severity and type of hospitalization were also collected. Amongst the 143 patients included, mental health symptoms were common (depression­19%; anxiety­27%; traumatic stress­39%; insomnia­33%) and more frequently reported in female than in male patients. Age, smoking status, comorbidities and illness severity were not found to significantly correlate with the presence of mood, sleep, or stress disorders. Finally, quality of life was worse for patients requiring ICU (p = 0.0057) or a longer hospital stay (p < 0.001) but was unaffected by factors such as sex and other measured outcomes. These findings highlight the need for appropriate intervention to properly manage the immediate and enduring mental health complications of COVID-19.

Dating the Origin and Estimating the Transmission Rates of the Major HIV-1 Clusters in Greece: Evidence about the Earliest Subtype A1 Epidemic in Europe.

Our aim was to estimate the date of the origin and the transmission rates of the major local clusters of subtypes A1 and B in Greece. Phylodynamic analyses were conducted in 14 subtype A1 and 31 subtype B clusters. The earliest dates of origin for subtypes A1 and B were in 1982.6 and in 1985.5, respectively. The transmission rate for the subtype A1 clusters ranged between 7.54 and 39.61 infections/100 person years (IQR: 9.39, 15.88), and for subtype B clusters between 4.42 and 36.44 infections/100 person years (IQR: 7.38, 15.04). Statistical analysis revealed that the average difference in the transmission rate between the PWID and the MSM clusters was 6.73 (95% CI: 0.86 to 12.60; p = 0.026). Our study provides evidence that the date of introduction of subtype A1 in Greece was the earliest in Europe. Transmission rates were significantly higher for PWID than MSM clusters due to the conditions that gave rise to an extensive PWID HIV-1 outbreak ten years ago in Athens, Greece. Transmission rate can be considered as a valuable measure for public health since it provides a proxy of the rate of epidemic growth within a cluster and, therefore, it can be useful for targeted HIV prevention programs.

Could adolescents be the vehicle that transfers a no-smoking rule from school to home?

INTRODUCTION: Banning smoking at home, schools, children's playgrounds and indoor environments, constitutes an integral part of tobacco control efforts to prevent uptake of smoking among young teenagers. We aimed at exploring the role of teenagers as facilitators of change in enforcing a home no-smoking rule following school-based anti-tobacco programs and examining the effect of home no-smoking rule on teenagers' intention to smoke. METHODS: A school-based intervention-control study was implemented during the 2016-2017 academic year among middle-school students in Athens, Greece. The experiential learning intervention was delivered using an interdisciplinary approach, bridging excerpts from ancient classical Greek myths and ancient classical literature, with their decoded archetypal symbols applied in a smoking and tobacco control paradigm. An anonymous selfadministered questionnaire was used at baseline, and at follow-up at 3 months to evaluate program effectiveness. A chi-squared test was used for categorical variables and a t-test for continuous variables. Cohen's distance (d) was employed to examine the intervention effect size. A two-tailed p≤0.05 was considered statistically significant using IBM SPSS V.22. RESULTS: In all, 351 students participated. At baseline, 47.5% in the intervention group reported a home no-smoking rule and 86% indicated being unlikely to smoke, these increased to 61.3% (p=0.016) and 98.2% (p<0.001) at followup, respectively. Cohen's d value was calculated to estimate the effect size of intervention. A large effect size of intervention was found in the intervention group (d=1.24), whilst d=0.19 in the control group. CONCLUSIONS: Our study showed that our intervention led to the increase of no-smoking rules at home and to a negative intention towards smoking of adolescents. Consequently, we provide evidence that students are effective vehicles for carrying anti-smoking messages to their home environment including the no-smoking rule. Additionally, we confirmed previous reports that home no-smoking rule is associated with a negative intention to smoke and risk of smoking.

Evaluation of a school-based, experiential-learning smoking prevention program in promoting attitude change in adolescents.

INTRODUCTION: School-based tobacco control programs exhibit great variety. Our study aimed to evaluate the effectiveness of an experiential learning smoking prevention program in facilitating knowledge acquisition, forging healthy attitudes, and decreasing intention to smoke. METHODS: A school-based intervention-control study was implemented during the 2016-2017 academic year among middle-school students in Athens, Greece. The experiential learning intervention was delivered using an interdisciplinary approach, bridging excerpts from ancient classical Greek myths, Aesop fables and ancient classical literature (Aristotle, Herodotus, Plutarch, Xenophon, Homer's Epics), with their decoded archetypal symbols applied in a smoking and tobacco control paradigm. An anonymous self-administered questionnaire was used at baseline and at follow-up at 3 months to evaluate program effectiveness. RESULTS: A total of 351 students participated in our study; 181 (51.6%) in the intervention group and 170 (48.4%) in the control group. The mean age of student participants was 13 years (SD=0.96). Students in the intervention group were more likely to improve their knowledge of the adverse effects of smoking, develop attitudes against smoking and report a negative intention to smoke in the first year following the intervention, compared to the control group. CONCLUSIONS: This study provides evidence that school-based experiential learning smoking prevention programs improve smoking-related knowledge, enhance anti-smoking attitudes and reinforce negative intentions toward tobacco products.

From Recession to Depression? Prevalence and Correlates of Depression, Anxiety, Traumatic Stress and Burnout in Healthcare Workers during the COVID-19 Pandemic in Greece: A Multi-Center, Cross-Sectional Study.

The COVID-19 pandemic has the potential to adversely affect the mental health of healthcare workers (HCWs). The public healthcare system in Greece was already facing serious challenges at the outset of the outbreak following years of austerity and an escalating refugee crisis. This multi-center, cross-sectional study aims to assess the levels and associated risk factors of anxiety, depression, traumatic stress and burnout of frontline staff in Greece. A total of 464 self-selected HCWs in six reference hospitals completed a questionnaire comprising sociodemographic and work-related information and validated psychometric scales. The proportion of HCWs with symptoms of moderate/severe depression, anxiety and traumatic stress were 30%, 25% and 33%, respectively. Burnout levels were particularly high with 65% of respondents scoring moderate/severe in emotional exhaustion, 92% severe in depersonalization and 51% low/moderate in personal accomplishment. Predictive factors of adverse psychological outcomes included fear, perceived stress, risk of infection, lack of protective equipment and low social support. The psychological burden associated with COVID-19 in healthcare professionals in Greece is considerable, with more than half experiencing at least mild mental health difficulties. Findings signal the need for immediate organizational and individually tailored interventions to enhance resilience and support wellbeing under pandemic conditions.

Human Immunodeficiency Virus Continuum of Care in 11 European Union Countries at the End of 2016 Overall and by Key Population: Have We Made Progress?

BACKGROUND: High uptake of antiretroviral treatment (ART) is essential to reduce human immunodeficiency virus (HIV) transmission and related mortality; however, gaps in care exist. We aimed to construct the continuum of HIV care (CoC) in 2016 in 11 European Union (EU) countries, overall and by key population and sex. To estimate progress toward the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 target, we compared 2016 to 2013 estimates for the same countries, representing 73% of the population in the region. METHODS: A CoC with the following 4 stages was constructed: number of people living with HIV (PLHIV); proportion of PLHIV diagnosed; proportion of those diagnosed who ever initiated ART; and proportion of those ever treated who achieved viral suppression at their last visit. RESULTS: We estimated that 87% of PLHIV were diagnosed; 92% of those diagnosed had ever initiated ART; and 91% of those ever on ART, or 73% of all PLHIV, were virally suppressed. Corresponding figures for men having sex with men were: 86%, 93%, 93%, 74%; for people who inject drugs: 94%, 88%, 85%, 70%; and for heterosexuals: 86%, 92%, 91%, 72%. The proportion suppressed of all PLHIV ranged from 59% to 86% across countries. CONCLUSIONS: The EU is close to the 90-90-90 target and achieved the UNAIDS target of 73% of all PLHIV virally suppressed, significant progress since 2013 when 60% of all PLHIV were virally suppressed. Strengthening of testing programs and treatment support, along with prevention interventions, are needed to achieve HIV epidemic control.

Vaccination and malaria prophylaxis among Greek international travelers to Asian destinations.

BACKGROUND: International travel is rapidly increasing worldwide, and the greatest increases have occurred in tropical and subtropical areas. The aim of the survey was to investigate the pre-travel health-seeking practices of travelers to Asian destinations. METHODS: A questionnaire-based survey was conducted at the Athens International Airport between the 1st of November 2011 and the 30th of April 2013. RESULTS: A total of 1666 adult travelers participated in the study, and 69.7% were men. The mean age of the participants was 39 years. Previous travel to tropical countries was reported by 69% of the participants. The most frequent destination was the Indian subcontinent (45.0%). The main reasons for travel were visiting friends and relatives (VFRs; 36.5%) and business (32.4%). Most of the participants traveled for <1 month (51.4%). Only 24.5% pursued pre-travel consultations. Vaccinations were administered to 14.4% of the participants, and of those, 77%, 73%, and 32.5% received hepatitis A, tetanus/diphtheria, and typhoid vaccines, respectively. Malaria prophylaxis was given to 12.2% of the participants. Logistic regression analysis revealed that being male and unemployed, having an elementary level of education, traveling to visiting friends and relatives, and short durations of travel were significant determinants of not seeking pre-travel consultations. CONCLUSION: Significant gaps were revealed in the vaccinations and malaria prophylaxes of travelers departing to Asia. Specific educational tools should be developed to improve the awareness of travelers to high-risk destinations.

Vaccination and Malaria Prevention among International Travelers Departing from Athens International Airport to African Destinations.

Background. International travel to Africa has grown dramatically over the last decade along with an increasing need to understand the health issues for travelers. The current survey aimed to assess vaccination and malaria prevention of travelers visiting Africa. Methods. A questionnaire-based survey was conducted from of November 1, 2011 to of April 30, 2013 at Athens International Airport. Results. A total of 360 travelers were studied; 68% were men. Their mean age was 39.9 years. Previous travel to tropical countries was reported by 71.9% of them. Most frequent destination was sub-Saharan Africa (60%). Most of them traveled for ≥1 month (62%). The main reason for travel was work (39.7%). Only 47% sought pretravel consultation. Hepatitis A, typhoid, and meningococcal vaccines were administered to 49.8%, 28%, and 26.6%, respectively, and malaria chemoprophylaxis to 66.8% of those who visited sub-Saharan Africa. A history of previous travel to a tropical country, elementary level of education, and traveling for visiting friends and relatives, and for short duration were significant determinants for not pursuing pretravel consultation. Conclusions. The current survey revealed important inadequacies in vaccine and malaria prophylaxis of travelers departing to Africa. Educational tools should be developed in order to improve awareness of travelers to risk destinations.

Pre-travel preparation practices among business travellers to tropical and subtropical destinations: results from the Athens International Airport Survey.

BACKGROUND: The number of business travellers from Greece to tropical and subtropical areas has recently increased. The study aimed to assess travel health preparation practices of business travellers departing to Africa, the Middle East and Asia. METHOD: A questionnaire-based survey was conducted at Athens International Airport, from 1st of November 2011 to 30th of April 2013. RESULTS: A total of 684 business travellers participated in the study; the majority were men (86.1%), of Greek nationality (95.3%), with tertiary education (90.8%) and employed (98%). Their mean age was 40 years; 62% and 26% of them were 35-49 and 19-34 years of age respectively. 84.8% were travelling alone. Most frequent destinations were the Middle East (46.8%) and sub-Saharan Africa (16%). For 23.5% of the travellers it was their first trip to a tropical or subtropical country. Only 58.8% pursued pre-travel health consultation; vaccination and malaria chemoprophylaxis were administered to 24.7% and 25.7% of the travellers, respectively. Hepatitis A and typhoid vaccination rates were lower than expected (70% and 35%, respectively). Nearly half of the travellers who visited malaria endemic areas did not receive any chemoprophylaxis. Having elementary education level, travelling to the Middle East or North Africa, travelling for less than 1 month duration, and staying in a house or a hotel were associated with a higher probability of not pursuing health consultation. CONCLUSIONS: Significant gaps were found in pre-travel health practices of business travellers departing to Africa, the Middle East and Asia. Strategies should be developed in order to improve awareness of business travellers.

Ηepatitis A and enteric fever in Greece, 2004-2011: a cross-sectional analysis.

BACKGROUND: In Greece the number of international travellers has increased significantly the past decade. AIM: To study the impact of international travels on the epidemiology of hepatitis A and enteric fever in Greece. METHODS: We studied cases of hepatitis A and enteric fever notified through the National Surveillance System from January 1, 2004 through December 31, 2011. RESULTS: A total of 921 cases of hepatitis A and 106 cases of enteric fever were notified; of them, 88 (9.5%) and 46 (43.4%) were travel-associated, respectively. Travellers returning from Eastern Europe and the Middle East accounted for most imported cases of hepatitis A (37 (43.5%) and 14 (16.5%) cases, respectively). The Indian subcontinent was the prevalent area of acquisition of travel-associated enteric fever, followed by the Middle East (35 (83.3%) and 4 (9.5%) cases, respectively). Foreign-born travellers accounted for 43 (48.8%) and 39 (86.6%) cases of travel-associated hepatitis A and enteric fever, respectively. Children <15 years accounted for 65.1% of hepatitis A cases and 7.7% among foreign-born travellers. Greek Roma accounted for 270 (29.3%) of all hepatitis A cases notified. CONCLUSIONS: International travels have a significant impact on the epidemiology of enteric fever in Greece, affecting mainly foreign travellers. Hepatitis A carries a significant burden of morbidity among Greek travellers and children of foreign nationality. There is a need to improve travel medicine services for travellers travelling to developing countries.

Preparedness of paediatric international travellers departing from Athens, Greece: an 18-month airport-based survey.

AIM: The number of children who travel to tropical and subtropical areas has increased. This study aimed to assess the preparedness of children departing from Greece to Africa and Asia, in terms of vaccination and malaria chemoprophylaxis. METHODS: An 18-month airport-based study was conducted in Athens between November 2011 and April 2013. RESULTS: Of the 183 children studied, 122 (66.7%) had a foreign nationality. Their main destinations were the Indian subcontinent (43.2%), South-East Asia (30.6%) and sub-Saharan Africa (14.2%). Just under three-quarters (73.2%) of the children were travelling to visit friends and relatives. Forty (21.9%) children had received pretravel services. Children visiting friends and relatives sought pretravel services less frequently than those who were not (17.9% versus 32.7%; p = 0.033). Female children and Greek nationals were significantly more likely to seeking pretravel services than males and foreign nationals (p = 0.007 and <0.001, respectively). The rabies and the typhoid fever vaccines were administered inadequately to children travelling to endemic areas, but malaria chemoprophylaxis was generally justified. CONCLUSION: Travel medicine services for children in Greece should be improved. There is a particular need to communicate with the parents of children visiting friends and relatives.

The impact of an antimicrobial cycling strategy for febrile neutropenia in a haematology unit.

Antibiotic cycling has been proposed as a strategy to combat the emergence of antimicrobial resistance but has been implemented with conflicting results. A cycling strategy including four broad-spectrum antimicrobial regimens administrated sequentially over 3-month cycles in patients with febrile neutropenia was implemented in a haematology unit, during a 2-year period (2001-2003). Compliance to the strategy ranged between 57 and 100% and overall successful clinical response was 83%. Resistance rates of Gram negatives remained either stable or decreased (for Pseudomonas aeruginosa) at the end of the cycling period and no rectal colonization with resistant pathogens was recorded during the study period. The incidence of Gram-negative infections showed a decreasing trend while Gram-positive infections and resistance rates remained unaffected and at low rates.

Knowledge and practices about rabies among travel medicine consultants in Greece.

The number of travellers returning with animal bites from rabies enzootic areas has increased in Greece. The aim of this study was to assess the knowledge of travel-associated risk and preventive measures for rabies. A questionnaire was sent to Travel Medicine consultants in all prefectures. Of 100 Travel Medicine consultants, advice about rabies was given to long-term travellers, business travellers, travellers to rural areas, and travellers engaged in animal activities in rabies enzootic countries by 44%, 22%, 58%, and 75% of them respectively. Avoidance of animals, post-exposure medical assistance, return back to their country, and special caution about children was recommended by 89%, 95%, 8%, and 65% of them, respectively. Rabies pre-exposure vaccination was recommended for travellers to rural areas, long-term travellers, and travellers engaged in animal activities by 61%, 35%, and 81% of them, respectively. Regarding post-exposure vaccination, 78% and 37% answered correctly with regards to travellers with no pre-exposure prophylaxis and travellers with pre-exposure prophylaxis, respectively. Counselling about rabies and management of risk exposure needs to be improved. Our findings indicate the need to promote continuous training in Travel Medicine in Greece and provide practical information about rabies prophylaxis.

Fatal cases associated with pandemic influenza A (H1N1) reported in Greece.

Between 18 May 2009 and 3 May 2010, a total of 149 fatal cases associated with pandemic influenza A (H1N1) were reported in Greece. Detailed case-based epidemiological information was available for the large majority of fatal cases. The time distribution follows an epidemic curve with a peak in the beginning of December 2009 and a second peak one month later. This is similar to that of laboratory confirmed cases and influenza-like illness cases from our sentinel surveillance system, with two weeks delay. The most commonly reported underlying conditions were chronic cardiovascular disease and immunosuppression, while the most frequently identified risk factor was obesity. These findings should be taken into consideration, when vaccination strategies are employed.

Determinants of intention to get vaccinated against novel (pandemic) influenza A H1N1 among health-care workers in a nationwide survey.

A nationwide survey was conducted in October-November 2009 to investigate determinants of intention to get vaccinated against novel (pandemic) influenza A H1N1 among health-care workers (HCWs) in Greece. Out of 12,879 participating HCWs (response rate: 12.1%) working in 152 (40%) of 380 health-care facilities in Greece, 2814 (21.8%) reported that they intend to get vaccinated against novel influenza A N1H1. Intention rates to get vaccinated increased with age, male sex, being a physician, history of vaccination against seasonal influenza, training in use of personal protective equipment and hand hygiene, and training and involvement in the management of novel influenza cases. Main reasons for refusing vaccination were concerns about vaccine safety (43.1%), inadequate information about the vaccine (27.8%), and perception that they were not at risk for contracting novel influenza (10.7%). Given the low rates of acceptance of pandemic vaccination among HCWs, as found in this study, public health bodies should consider the implementation of a mandatory vaccination policy for HCWs for future pandemics, in order to prevent nosocomial transmission and to protect patients at high-risk for influenza-related complications and death, and to assure the continuity of the essential health-care infrastructure. New strategies should be explored to built safety perception towards influenza vaccines and enhance vaccination rates among HCWs.
