RESUMO

The COVID-19 pandemic led to unprecedented stress on healthcare systems worldwide, forming settings of concern for increasing antimicrobial resistance. We investigated the impact of SARS-CoV-2 preventive measures against healthcare-associated infections (HAIs) from antibiotic-resistant bacteria in two tertiary-care hospitals. We compared infection rates between March 2019 and February 2020 (pre-intervention period) and March 2020 and February 2021 (COVID-19 intervention period) from drug-resistant ESKAPEE bacteria (methicillin-resistant Staphylococcus aureus; vancomycin-resistant Enterococci; carbapenem-resistant Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter species and Escherichia coli). Over 24 months, 586 drug-resistant ESKAPEE HAIs occurred in 439 patients (0.3% of 179,629 inpatients) with a mean age of 63 years, with 43% being treated in intensive care units (ICUs), and having a 45% inpatient mortality rate. Interrupted time series analysis revealed increasing infection rates before the intervention that were sharply interrupted by abrupt drops for most pathogens and henceforth remained stable in the ICUs but progressively increased in ordinary wards. In the ICUs, the pooled infection rate was 44% lower over the intervention period compared to the pre-intervention period (incidence rate ratio (IRR) 0.56, 95%CI 0.41-0.75, p < 0.001). Pooled infection rates in the wards were slightly higher over the COVID-19 period (IRR 1.12, 95%CI 0.87-1.45, p = 0.368). The findings confirmed the ancillary beneficial impact of the enhanced bundle of transmission-based precautions adopted against SARS-CoV-2 in rapidly constraining antimicrobial-resistant HAIs in two Greek hospitals.

RESUMO

Greece opened its points of entry on July 1, 2020, with specific guidelines for travellers arriving by sea, air or land. The aim of this article is to examine the effect of tourism on the long term course of the Coronavirus Disease 2019 (COVID-19) pandemic during the pre-vaccination era (June to December 2020) on the popular Greek island of Crete. To achieve this, a cross-sectional serosurvey, repeated at monthly intervals, was conducted to compare the seroprevalence in Crete with seroprevalence in the mainland of Greece. Crete welcomed nearly 2,000,000 travellers during the 2020 summer season. Left-over serum samples were collected and obtained from public and private laboratories located in Greece, including the island of Crete. These samples were tested for the presence of anti-SARS-CoV-2 IgG antibodies. A total of 55,938 samples were collected, 3,785 of which originated from Crete. In Crete, the seroprevalence ranged between 0% (June 2020) and 2.58% (December 2020), while the corresponding seroprevalence in Greece was 0.19% and 10.75%, respectively. We identified 4.16 times lower seropositivity in Crete (2.58%) in comparison with the mainland of Greece (10.75%) during December 2020. Moreover, the monthly infection fatality rate (IFR) in Crete was calculated at 0.09%, compared with 0.21% in mainland Greece for December 2020. The island of Crete presented more than four times lower seroprevalence than the mainland of Greece, despite being a highly attractive tourist destination. This evidence supports the idea that tourism may not have affected the long term course of the COVID-19 pandemic in Greece. However, due to contradicting results from previous studies, further investigation is needed.

RESUMO

Bacterial antibiotic resistance (AMR) is a significant threat to public health, with the sentinel 'ESKAPEE' pathogens, being of particular concern. A cohort study spanning 5.5 years (2016-2021) was conducted at a provincial general hospital in Crete, Greece, to describe the epidemiology of ESKAPEE-associated bacteraemia regarding levels of AMR and their impact on patient outcomes. In total, 239 bloodstream isolates were examined from 226 patients (0.7% of 32 996 admissions) with a median age of 75 years, 28% of whom had severe comorbidity and 46% with prior stay in ICU. Multidrug resistance (MDR) was lowest for Pseudomonas aeruginosa (30%) and Escherichia coli (33%), and highest among Acinetobacter baumannii (97%); the latter included 8 (22%) with extensive drug-resistance (XDR), half of which were resistant to all antibiotics tested. MDR bacteraemia was more likely to be healthcare-associated than community-onset (RR 1.67, 95% CI 1.04-2.65). Inpatient mortality was 22%, 35% and 63% for non-MDR, MDR and XDR episodes, respectively (P = 0.004). Competing risks survival analysis revealed increasing mortality linked to longer hospitalisation with increasing AMR levels, as well as differential pathogen-specific effects. A. baumannii bacteraemia was the most fatal (14-day death hazard ratio 3.39, 95% CI 1.74-6.63). Differences in microbiology, AMR profile and associated mortality compared to national and international data emphasise the importance of similar investigations of local epidemiology.

RESUMO

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.

RESUMO

Hyponatremia is the most common electrolyte disorder, commonly affecting older hospitalized individuals; however, the literature is not clear regarding its effect on mortality. The aim of this 2-year observational prospective cohort study was to evaluate the mortality and re-admission rates, the clinical and laboratory characteristics and the causes of hyponatremia in patients older than 65 years admitted with a corrected serum sodium of 130 mEq/L or less in an internal medicine ward of a tertiary Greek university hospital. During the observation period, 138 patients (mean age 80.5 years, 36.2% male) fulfilled the inclusion criteria and were prospectively followed for 1 year after admission. Symptoms of hyponatremia were present in 59.4% of patients. Hypovolemia was the main sole cause of hyponatremia, but in about one third of patients, hyponatremia was multifactorial. Only a low proportion of patients (12.3%) fulfilled the criteria of the syndrome of inappropriate antidiuresis (SIAD) at admission according to the current guidelines. The re-admission rates at 3- and 12-months following discharge was 34.2% and 51.8%, respectively. Mortality during hospitalization was 17.4% and was higher compared to non-hyponatremic admitted older patients, while the total mortality at 1 year after admission was 28.3%, indicating that hyponatremia at admission is a marker of significant mortality during and after hospitalization in elderly patients.

RESUMO

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.

RESUMO

BACKGROUND: We report the results of INICC surveillance study from 2013 to 2018, in 664 intensive care units (ICUs) in 133 cities, of 45 countries, from Latin-America, Europe, Africa, Eastern-Mediterranean, Southeast-Asia, and Western-Pacific. METHODS: Prospective data from patients hospitalized in ICUs were collected through INICC Surveillance Online System. CDC-NHSN definitions for device-associated healthcare-associated infection (DA-HAI) were applied. RESULTS: We collected data from 428,847 patients, for an aggregate of 2,815,402 bed-days, 1,468,216 central line (CL)-days, 1,053,330 mechanical ventilator (MV)-days, 1,740,776 urinary catheter (UC)-days. We found 7,785 CL-associated bloodstream infections (CLAB), 12,085 ventilator-associated events (VAE), and 5,509 UC-associated urinary tract infections (CAUTI). Pooled DA-HAI rates were 5.91% and 9.01 DA-HAIs/1,000 bed-days. Pooled CLAB rate was 5.30/1,000 CL-days; VAE rate was 11.47/1,000 MV-days, and CAUTI rate was 3.16/1,000 UC-days. P aeruginosa was non-susceptible (NS) to imipenem in 52.72% of cases; to colistin in 10.38%; to ceftazidime in 50%; to ciprofloxacin in 40.28%; and to amikacin in 34.05%. Klebsiella spp was NS to imipenem in 49.16%; to ceftazidime in 78.01%; to ciprofloxacin in 66.26%; and to amikacin in 42.45%. coagulase-negative Staphylococci and S aureus were NS to oxacillin in 91.44% and 56.03%, respectively. Enterococcus spp was NS to vancomycin in 42.31% of the cases. CONCLUSIONS: DA-HAI rates and bacterial resistance are high and continuous efforts are needed to reduce them.

RESUMO

BACKGROUND: Surveillance is essential to all aspects of management of healthcare-associated infections (HAIs) in critically ill children, where data are limited. We conducted an active surveillance study to elucidate epidemiology, resistance, antimicrobial treatment practices and outcomes of pediatric intensive care unit-acquired HAIs in a southern European country. METHODS: Four Greek pediatric intensive care unit encounters (153 patients, 2183 patient-days) during a 6-month period participated using the European Centre for Disease Prevention and Control HAI-net ICU (v2.2) protocol. Bloodstream infections and device-associated HAIs were recorded. Clinical severity, isolated pathogens, antimicrobial resistance and antibiotic prescriptions were collected on a daily basis. Mortality and excess length of stay due to HAI were also assessed. RESULTS: Overall rate of HAIs was 18.3 per 1000 patient-days. Aggregate rates for device-associated HAI were: catheter-related bloodstream infection 2.32, intubation-associated pneumonia 10.5, and catheter-associated urinary tract infection 4.6 per 1000 device-days. Children with HAI (n = 28, 18.3%) had higher severity of illness (Pediatric Risk Mortality Score 7.5 vs. 4, P < 0.001), longer hospitalization (23 vs. 6 days, P < 0.001), but not higher mortality, compared with those without. Most frequent recovered pathogens were Klebsiella pneumoniae (40%), Pseudomonas aeruginosa (22.5%), Acinetobacter baumannii (12.5%), with respective carbapenem resistance 50%, 44% and 80%, and Staphylococcus aureus (12.5%). Total antibiotic use was 2142 days of treatment per 1000 patient-days. CONCLUSIONS: Our study, based on the updated ECDC HAI-net ICU (v2.2) protocol, effectively addresses the significant burden of HAIs in critically ill children in Greece. Using a well-standardized system facilitates inter- and intra-countries reliable recordings and comparative assessments of infection control programs.

RESUMO

Pandrug-resistant A. baumannii (PDRAB) is increasingly being reported but remains rare. Several case studies show that A. baumannii can acquire resistance to last resort antibiotics during treatment by single-step chromosomal mutations. However, re-emergence of the ancestral susceptible strain after withdrawal of antibiotics has been described, possibly due to fitness cost associated with acquired resistance. Therefore, PDRAB may be a transient phenotype. Epidemiological data to show this process in larger cohorts are currently lacking. In this study of 91 hospitalized patients with PDRAB we showed the frequent (60%) isolation of non-PDRAB, often susceptible only to colistin, aminoglycosides and/or tigecycline, preceding and/or following PDRAB isolation. However, the isolation of PDRAB in two outpatients, 25 and 36 days after their discharge from the hospital, suggests the potential of some PDRAB strains to persist even in the absence of antimicrobial pressure.

RESUMO

The management of carbapenem-resistant infections is often based on polymyxins, tigecycline, aminoglycosides and their combinations. However, in a recent systematic review, we found that Gram-negative bacteria (GNB) co-resistant to carbapanems, aminoglycosides, polymyxins and tigecycline (CAPT-resistant) are increasingly being reported worldwide. Clinical data to guide the treatment of CAPT-resistant GNB are scarce and based exclusively on few case reports and small case series, but seem to indicate that appropriate (in vitro active) antimicrobial regimens, including newer antibiotics and synergistic combinations, may be associated with lower mortality. In this review, we consolidate the available literature to inform clinicians dealing with CAPT-resistant GNB about treatment options by considering the mechanisms of resistance to carbapenems. In combination with rapid diagnostic methods that allow fast detection of carbapenemase production, the approach proposed in this review may guide a timely and targeted treatment of patients with infections by CAPT-resistant GNB. Specifically, we focus on the three most problematic species, namely Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii. Several treatment options are currently available for CAPT-resistant K. pneumonia. Newer ß-lactam-ß-lactamase combinations, including the combination of ceftazidime/avibactam with aztreonam against metallo-ß-lactamase-producing isolates, appear to be more effective compared to combinations of older agents. Options for P. aeruginosa (especially metallo-ß-lactamase-producing strains) and A. baumannii remain limited. Synergistic combination of older agents (e.g., polymyxin- or fosfomycin-based synergistic combinations) may represent a last resort option, but their use against CAPT-resistant GNB requires further study.

RESUMO

BACKGROUND: Infections with multidrug resistant (MDR) bacteria in hospital settings have substantial implications in terms of clinical and economic outcomes. However, due to clinical and methodological heterogeneity, estimates about the attributable economic and clinical effects of healthcare-associated infections (HAI) due to MDR microorganisms (MDR HAI) remain unclear. The objective was to review and synthesize the evidence on the impact of MDR HAI in adults on hospital costs, length of stay, and mortality at discharge. METHODS AND FINDINGS: Literature searches were conducted in PubMed/MEDLINE, and Google Scholar databases to select studies that evaluated the impact of MDR HAI on economic and clinical outcomes. Eligible studies were conducted in adults, in order to ensure homogeneity of populations, used propensity score matched cohorts or included explicit confounding control, and had confirmed antibiotic susceptibility testing. Risk of bias was evaluated, and effects were measured with ratios of means (ROM) for cost and length of stay, and risk ratios (RR) for mortality. A systematic search was performed on 14th March 2019, re-run on the 10th of June 2019 and extended the 3rd of September 2019. Small effect sizes were assessed by examination of funnel plots. Sixteen articles (6,122 patients with MDR HAI and 8,326 patients with non-MDR HAI) were included in the systematic review of which 12 articles assessed cost, 19 articles length of stay, and 14 mortality. Compared to susceptible infections, MDR HAI were associated with increased cost (ROM 1.33, 95%CI [1.15; 1.54]), prolonged length of stay (ROM 1.27, 95%CI [1.18; 1.37]), and excess in-hospital mortality (RR 1.61, 95%CI [1.36; 1.90]) in the random effects models. Risk of publication bias was only found to be significant for mortality, and overall study quality good. CONCLUSIONS: MDR HAI appears to be strongly associated with increases in direct cost, prolonged length of stay and increased mortality. However, further comprehensive studies in this setting are warranted. TRIAL REGISTRATION: PROSPERO (CRD42019126288).

RESUMO

BACKGROUND: The literature on the epidemiology, mortality and treatment of pandrug-resistant (PDR) Gram-negative bacteria (GNB) is scarce, scattered and controversial. OBJECTIVES: To consolidate the relevant literature and identify treatment options for PDR GNB infections. METHODS: A systematic search in MEDLINE, Scopus and clinical trial registries was conducted. Studies reporting PDR clinical isolates were eligible for review if susceptibility testing for all major antimicrobials had been performed. Characteristics and findings of retrieved studies were qualitatively synthesized. RESULTS: Of 81 studies reviewed, 47 (58%) were published in the last 5 years. The reports reflected a worldwide dissemination of PDR GNB in 25 countries in 5 continents. Of 526 PDR isolates reported, Pseudomonas aeruginosa (n=175), Acinetobacter baumannii (n=172) and Klebsiella pneumoniae (n=125) were most common. PDR GNB were typically isolated in ICUs, but several studies demonstrated wider outbreak potential, including dissemination to long-term care facilities and international spread. All-cause mortality was high (range 20%-71%), but appeared to be substantially reduced in studies reporting treatment regimens active in vitro. No controlled trial has been performed to date, but several case reports and series noted successful use of various regimens, predominantly synergistic combinations, and in selected patients increased exposure regimens and newer antibiotics. CONCLUSIONS: PDR GNB are increasingly being reported worldwide and are associated with high mortality. Several treatment regimens have been successfully used, of which synergistic combinations appear to be most promising and often the only available option. More pharmacokinetic/pharmacodynamic and outcome studies are needed to guide the use of synergistic combinations.

RESUMO

Concern exists in Europe about the possibility of importation of infectious diseases due to the recent influx of migrants and refugees after 2011. In this retrospective 6-year study, we examined the epidemiology of fever of unknown origin (FUO) in Greece over the past years. Forty-eight patients with classical FUO were included. The proportion of infectious causes of FUO (29.2%) was similar to previous studies in Greece and all infections were endemic to the area. Disease-related mortality was 12.5% and no deaths due to infection were recorded. In conclusion, none of the diagnosed infectious causes of FUO raised concerns about the possibility of imported diseases or pathogens. These results re-inforce the perception that migrants and refugees are not carriers of communicable diseases that can cause public health problems to European countries.

RESUMO

BACKGROUND: We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS: During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS: Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS: Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

RESUMO

OBJECTIVE: Combined antiretroviral treatment (cART) results in profound immunologic improvement, but it is unclear whether CD4 cell counts return to levels similar to those of HIV-negative individuals. We explore long-term CD4 cell count evolution post-cART and its association with baseline levels, virologic suppression, pre-cART cumulative viremia and other factors. DESIGN: Data were derived from the AMACS. Included individuals were adults who started cART, at least 2003, while previously ART-naive. METHODS: Changes in CD4 cell counts were modeled through piecewise linear mixed models. RESULTS: A total of 3405 individuals were included. The majority was male (86.0%), homosexual (58.8%) with median (IQR) age at cART initiation 36 (31-44) years and a median (IQR) follow-up of 3.9 (2.0-6.9) years. Most persons (57%) starting cART with less than 200 cells/µl did not reach 600 cells/µl after 7 years of treatment. Those starting cART with 200-349 CD4 cells/µl could reach 600 cells/µl within less than 2 years of fully suppressive treatment. Probability of CD4 normalization (i.e. >800 cells/µl) after 7 years of suppressive treatment was 24 and 46% for those starting treatment with less than 200 or 200-349 CD4 cells/µl, respectively. Lower pre-cART cumulative viremia was associated with faster CD4 recovery. CD4 cell count increases after 4 years were either insignificant or very slow, irrespectively of baseline levels. CONCLUSION: cART initiation before CD4 cell count drops below 350 cells/µl is crucial for achieving normal CD4 levels. These findings underline the importance of timely diagnosis and cART initiation as the risk of both AIDS and non-AIDS-related morbidity/mortality remains increased in patients with incomplete CD4 recovery.

RESUMO

Gemella species are catalase-negative, facultative anaerobic, Gram-positive cocci, which are part of the human oral microbiome and may occasionally cause systemic infections. Infective endocarditis (IE) has been reported as the most common infection caused by Gemella species. We report the first case of IE due to Gemella sanguinis in Greece, in a patient with bicuspid aortic valve and review the available literature. The patient was successfully treated with antibiotics and aortic valve replacement.

RESUMO

BACKGROUND: Elderly patients are underrepresented in the studies concerning anticoagulation therapy (AT) in atrial fibrillation (AF), while patients' frailty status is lacking in most of the studies. OBJECTIVE: Our objective was to evaluate AT in AF elderly patients and study the effect of patients' frailty status on their long-term AT. METHODS: We conducted an observational prospective study that enrolled consecutive AF patients (≥ 75 years) who were hospitalized in the Department of Internal Medicine of the University Hospital of Heraklion, Crete, Greece from 1 June 2015 to 1 June 2016. We recorded the AT on admission and at discharge, all-cause mortality, and hospital readmission in a follow-up period of 1 year after hospital discharge. Frailty status was assessed by pre-established scores. RESULTS: One hundred and four consecutive patients (49% male; median age 87 years) were enrolled, 78 (78.8%) of whom received AT at discharge. Patients who did not receive AT at discharge had a higher HEMORR2HAGES (Hepatic or renal disease, Ethanol abuse, Malignancy, Older age, Reduced platelet count or function, Re-bleeding, Hypertension, Anemia, Genetic factors, Excessive fall risk and Stroke) score (5.5 ± 1.15 vs. 4.79 ± 1.68; p = 0.032), a lower Katz score (2.48 ± 2.23 vs. 4.08 ± 2.25; p = 0.006), and a higher Clinical Frailty Scale score (7 ± 1.95 vs. 5.57 ± 2.05; p = 0.006). Sixty-five patients (62.5%) were readmitted to a hospital during the follow-up period. In-hospital death occurred in five patients (4.8%) and 57 patients (57.6%) died within the follow-up period. CONCLUSION: A high percentage of the elderly AF patients did not receive AT, even at discharge. Patients who did not receive AT at discharge had higher bleeding and frailty scores. In the 1-year follow-up period after hospital discharge, high all-cause mortality and a high number of hospital readmissions were recorded.

RESUMO

Cytomegalovirus (CMV) rarely causes disease in immunocompetent individuals but may cause severe disease in immunocompromised patients. We report the case of a young woman who had undergone multiple transfusions and splenectomy for homozygous ß-thalassemia. She presented with prolonged fever and respiratory distress. Although broad-spectrum antibiotic therapy had initially been administered, the patient had clinically deteriorated. Serology and molecular blood testing established CMV infection and viremia. Computed tomography of the chest demonstrated pneumonitis and she was successfully treated with a 3-week administration of ganciclovir. In ß-thalassemia patients who undergo splenectomy necessitating multiple blood transfusions, CMV infection should be considered as a differential diagnosis.

RESUMO

BACKGROUND: In this first attempt to suggest achievable standards for improvement in hospital infection prevention and control (IPC) in Greece, we assessed main IPC structure and process indicators emphasizing hand hygiene. METHODS: Acute-care hospitals across the country participated in a cross-sectional survey by completing the World Health Organization Hand Hygiene Self-assessment Framework (HHSAF) and by providing hospital-level IPC indicators. RESULTS: Seventeen hospitals completed the survey, comprising 14% of the country's public hospitals. Median IPC staffing levels were 0.8 nurses and 0.5 doctors per 250 beds. Few hospitals implemented full multimodal IPC programs. The HHSAF indicated that appropriate hand hygiene practices and promotion strategies were in place in most hospitals, but the mean HHSAF score of 289 was lower compared with studies in Italy (mean, 332; P = .040) and the United States (mean, 373; P < .001). Presence of 1 additional IPC nurse was independently associated with increases of 53% in the HHSAF median score for training-education (P = .035) and by 38% in the lower 30th percentile HHSAF score for safety climate (P = .049). CONCLUSIONS: Surveyed hospitals are, on average, at an intermediate level in hand hygiene practice but require improvements on training-education, evaluation-feedback, and safety climate. Ensuring adequate IPC nurse staffing levels and systematically implementing multimodal IPC programs may lead to substantial improvements.
