<p>To assess the potential benefit from the implementation of the Kaiser Permanente early-onset sepsis calculator (EOS-C), in terms of antibiotic use and requested laboratory tests, in a network of neonatal intensive care units (NICUs) in Greece, and to determine the incidence of early-onset sepsis (EOS) in Greek NICUs, a prospective surveillance study was conducted in 7 NICUs between April 2018 and June 2019. Data were collected for all newborns ≥ 34&nbsp;weeks' gestation receiving empiric antibiotic therapy within the first 3&nbsp;days of life. The number of live births and positive blood or cerebrospinal fluid cultures within the first 3&nbsp;days of life were used for calculation of EOS incidence. Evaluation of possible impact of implementing the calculator was done by comparing the clinicians' recorded management to the calculator's suggested course of action. The unit-specific incidence of culture-proven EOS ranged between 0 and 2.99/1000 live births. The weighted incidence rate for all 7 units was 1.8/1000 live births. Management of EOS guided by the calculator could lead to a reduction of empiric antibiotic initiation up to 100% for the group of "well-appearing" neonates and 86% for "equivocal," lowering exposure to antibiotics by 4.2 and 3.8&nbsp;days per neonate, respectively. Laboratory tests for blood cultures drawn could be reduced by up to 100% and 68%, respectively. Sensitivity of the EOS-C in identifying neonates with positive blood cultures was high.Conclusion: Management strategies based on the Kaiser Permanente neonatal sepsis calculator may significantly reduce antibiotic exposure, invasive diagnostic procedures, and hospitalizations in late preterm and term neonates. What is Known: • Neonates are frequently exposed to antibiotics for presumed EOS. • The Kaiser Permanente sepsis calculator can reduce antibiotic exposure in neonates.. What is New: • EOS calculator can be an effective antibiotic stewardship tool in a high prescribing country and can reduce invasive diagnostic procedures and mother-baby separation. • Incidence of EOS in Greece is higher compared to other European countries.</p>

Antibiotics are commonly prescribed in Neonatal Intensive Care Units (NICU), where stewardship interventions are challenging. Lowering antibiotic consumption is desperately needed in Greece, a country with high antibiotic resistance rates. We sought to assess the effectiveness of a low-cost and -resource intervention to reduce antibiotic use in Greek NICUs implementing a "low-hanging fruit" approach. A prospective quasi-experimental study was conducted in 15/17 public NICUs in Greece (9/2016-06/2019). The intervention selected was discontinuation of antibiotics within 5 days for neonates with gestational age ≥ 37 weeks, no documented signs or symptoms of sepsis, CRP ≤ 10 mg/L and negative cultures within 3 days of antibiotic initiation. Impact was evaluated by the percentage of discontinued regimens by day 5, length of therapy (LOT) and stay. Trends of antibiotic consumption were assessed with days of therapy (DOT) per 1000 patient-days. Overall, there was a 9% increase ( = 0.003) of antibiotic discontinuation in ≤5 days. In total, 7/13 (53.8%) units showed a ≥10% increase. Overall, 615 days on antibiotics per 1000 patients were saved. Interrupted time-series analysis established a declining trend in DOT/1000 patient-days relative to the pre-intervention trend ( = 0.002); a monthly decrease rate of 28.96 DOT/1000 patient-days ( = 0.001, 95%CI [-45.33, -12.60]). The intervention had no impact on antibiotic choice. Antibiotic use was successfully reduced in Greek NICUs using a "low-hanging fruit" approach. In resource-limited settings, similar targeted stewardship interventions can be applied.

<p><strong>BACKGROUND: </strong>Epidemiological data indicate that a large part of population needs to be vaccinated to achieve herd immunity. Hence, it is of high importance for public health officials to know whether people are going to get vaccinated for COVID-19. The objective of the present study was to examine the willingness of adult residents in Greece to receive a COVID-19 vaccine.</p>

<p><strong>METHODS: </strong>A cross-sectional was survey conducted among the adult general population of Greece between April 28, 2020 to May 03, 2020 (last week of lockdown), using a mixed methodology for data collection: Computer Assisted Telephone Interviewing (CATI) and Computer Assisted web Interviewing (CAWI). Using a sample size calculator, the target sample size was found to be around 1000 respondents. To ensure a nationally representative sample of the urban/rural population according to the Greek census 2011, a proportionate stratified by region systematic sampling procedure was used to recruit particpants. Data collection was guided through a structured questionnaire. Regarding willingness to COVID-19 vaccination, participants were asked to answer the following question: "If there was a vaccine available for the novel coronavirus, would you do it?"</p>

<p><strong>RESULTS: </strong>Of 1004 respondents only 57.7% stated that they are going to get vaccinated for COVID-19. Respondents aged &gt; 65 years old, those who either themselves or a member of their household belonged to a vulnerable group, those believing that the COVID-19 virus was not developed in laboratories by humans, those believing that coronavirus is far more contagious and lethal compared to the H1N1 virus, and those believing that next waves are coming were statistically significantly more likely to be willing to get a COVID-19 vaccine. Higher knowledge score regarding symptoms, transmission routes and prevention and control measures against COVID-19 was significantly associated with higher willingness of respondents to get vaccinated.</p>

<p><strong>CONCLUSION: </strong>A significant proportion of individuals in the general population are unwilling to receive a COVID-19 vaccine, stressing the need for public health officials to take immediate awareness-raising measures.</p>

<p><strong>BACKGROUND: </strong>Pressure ulcers are a major problem for national healthcare systems since they frequently occur in hospitalized patients, negatively affecting patients' quality of life and extending duration of hospitalization.</p>

<p><strong>OBJECTIVE: </strong>To systematically review the available evidence regarding the incidence, prevalence, attributable length of stay and cost of hospital-acquired pressure ulcers in pediatric populations.</p>

<p><strong>DESIGN: </strong>A systematic review and meta-analysis.</p>

<p><strong>METHODS: </strong>A systematic search (March 15, 2020) was conducted in PubMed, Scopus, and ProQuest databases. Cross-sectional and cohort studies of neonates and children aged &lt;21 years old were eligible for inclusion when full text was available in English and data for at least one of the following criteria was provided: incidence, prevalence, attributable length of stay or healthcare cost due to hospital-acquired pressure ulcers. Study quality was evaluated using the Joanna Briggs Institute Critical Appraisal Tools. Random effects models were used to synthesize data. Heterogeneity and publication bias were evaluated.</p>

<p><strong>RESULTS: </strong>From the 1055 studies appeared in literature search, 21 studies were included in the systematic review and 19 were included in the meta-analysis. The overall prevalence ranged from 0.47% to 31.2% and cumulative incidence ranged from 3.7% to 27%. The pooled prevalence was estimated at 7.0% (95% confidence interval (CI): 4.3%-10.4%) and the pooled cumulative incidence at 14.9% (95% CI: 7.7%-23.9%). The pooled prevalence among neonates was 27.0% (95% CI: 22.1%-33.1%) among children aged less than 1 year old was 19.2% (95% CI: 9.4%-31.3%) and among children older than 1 year was 12.3% (95% CI: 2.3%-27.9%). The cumulative incidence of hospital-acquired pressure ulcers in neonates was 9.8% (95% CI: 2.9%-19.8%) and in children aged &lt;1 year old was 11.3% (95% CI: 4.4%-20.7%), while no data was available to estimate this figure for children older than 1 year. The attributable length of stay ranged from 0.9 to 14.1 days and the attributable cost ranged from $894.69 to $98,730.24 (United States dollars; value of a dollar in 2020) per patient with hospital-acquired pressure ulcers.</p>

<p><strong>CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: </strong>The results of this meta-analysis indicate that hospital-acquired pressure ulcers occur frequently in pediatric populations with a great variation across different age groups. Moreover, although limited data are available, it seems that hospital-acquired pressure ulcers have significant economic implications for the healthcare systems since they prolong patients' hospitalization stay; these findings further highlight the need for implementation of patient-based prevention strategies.</p>

<p><strong>BACKGROUND: </strong>Active daily surveillance of central-line days (CLDs) in the assessment of rates of central-line-associated bloodstream infections (CLABSIs) is time-consuming and burdensome for healthcare workers. Sampling of denominator data is a method that could reduce the time necessary to conduct active surveillance.</p>

<p><strong>OBJECTIVE: </strong>To evaluate the accuracy of various sampling strategies in the estimation of CLABSI rates in adult and pediatric units in Greece.</p>

<p><strong>METHODS: </strong>Daily denominator data were collected across Greece for 6 consecutive months in 33 units: 11 adult units, 4 pediatric intensive care units (PICUs), 12 neonatal intensive care units (NICUs), and 6 pediatric oncology units. Overall, 32 samples were evaluated using the following strategies: (1) 1 fixed day per week, (2) 2 fixed days per week, and (3) 1 fixed week per month. The CLDs for each month were estimated as follows: (number of sample CLDs/number of sampled days) × 30. The estimated CLDs were used to calculate CLABSI rates. The accuracy of the estimated CLABSI rates was assessed by calculating the percentage error (PE): [(observed CLABSI rates - estimated CLABSI rates)/observed CLABSI rates].</p>

<p><strong>RESULTS: </strong>Compared to other strategies, sampling over 2 fixed days per week provided the most accurate estimates of CLABSI rates for all types of units. Percentage of estimated CLABSI rates with PE ≤±5% using the strategy of 2 fixed days per week ranged between 74.6% and 88.7% in NICUs. This range was 79.4%-94.1% in pediatric onology units, 62.5%-91.7% in PICUs, and 80.3%-92.4% in adult units. Further evaluation with intraclass correlation coefficients and Bland-Altman plots indicated that the estimated CLABSI rates were reliable.</p>

<p><strong>CONCLUSION: </strong>Sampling over 2 fixed days per week provides a valid alternative to daily collection of CLABSI denominator data. Adoption of such a monitoring method could be an important step toward better and less burdensome infection control and prevention.</p>
