We compared hospital-acquired catheter-related bacteremia (CRB) episodes diagnosed at acute care hospitals in Catalonia, Spain, during the COVID-19 pandemic in 2020 with those detected during 2007-2019. We compared the annual observed and predicted CRB rates by using the negative binomial regression model and calculated stratified annual root mean squared errors. A total of 10,030 episodes were diagnosed during 2007-2020. During 2020, the observed CRB incidence rate was 0.29/10 patient-days, whereas the predicted CRB rate was 0.14/10 patient-days. The root mean squared error was 0.153. Thus, a substantial increase in hospital-acquired CRB cases was observed during the COVID-19 pandemic in 2020 compared with the rate predicted from 2007-2019. The incidence rate was expected to increase by 1.07 (95% CI 1-1.15) for every 1,000 COVID-19-related hospital admissions. We recommend maintaining all CRB prevention efforts regardless of the coexistence of other challenges, such as the COVID-19 pandemic.

Background Organ-space surgical site infections (SSI) are the most serious and costly infections after colorectal surgery. Most previous studies of risk factors for SSI have analysed colon and rectal procedures together. The aim of the study was to determine whether colon and rectal procedures have different risk factors and outcomes for organ-space SSI. Methods A multicentre observational prospective cohort study of adults undergoing elective colon and rectal procedures at 10 Spanish hospitals from 2011 to 2014. Patients were followed up until 30 days post-surgery. Surgical site infection was defined according to the Centers for Disease Control and Prevention criteria. Oral antibiotic prophylaxis (OAP) was considered as the administration of oral antibiotics the day before surgery combined with systemic intravenous antibiotic prophylaxis. Results Of 3,701 patients, 2,518 (68%) underwent colon surgery and 1,183 (32%) rectal surgery. In colon surgery, the overall SSI rate was 16.4% and the organ-space SSI rate was 7.9%, while in rectal surgery the rates were 21.6% and 11.5% respectively ( p  < 0.001). Independent risk factors for organ-space SSI in colon surgery were male sex (Odds ratio -OR-: 1.57, 95% CI: 1.14–2.15) and ostomy creation (OR: 2.65, 95% CI: 1.8–3.92) while laparoscopy (OR: 0.5, 95% CI: 0.38–0.69) and OAP combined with intravenous antibiotic prophylaxis (OR: 0.7, 95% CI: 0.51–0.97) were protective factors. In rectal surgery, independent risk factors for organ-space SSI were male sex (OR: 2.11, 95% CI: 1.34–3.31) and longer surgery (OR: 1.49, 95% CI: 1.03–2.15), whereas OAP with intravenous antibiotic prophylaxis (OR: 0.49, 95% CI: 0.32–0.73) was a protective factor. Among patients with organ-space SSI, we found a significant difference in the overall 30-day mortality, being higher in colon surgery than in rectal surgery (11.5% vs 5.1%, p  = 0.04). Conclusions Organ-space SSI in colon and rectal surgery has some differences in terms of incidence, risk factors and outcomes. These differences could be considered for surveillance purposes and for the implementation of preventive strategies. Administration of OAP would be an important measure to reduce the OS-SSI rate in both colon and rectal surgeries.

Background: Catheter-related bloodstream infections (CRBSIs) are one of the most frequent causes of heathcare-associated infections and an important cause of preventable death. Central venous catheters (CVC) have been considered the most worrisome origin of CRBSI. Implemented preventive measures at most hospitals and published guidelines for the prevention of vascular catheter infections have focused mostly on CVCs. However, peripherally inserted venous catheters (PIVC)–related bloodstream infections have increased in recent years and are currently among the top 10 patient safety concerns for 2019. Objective: We describe the changes in the epidemiology of catheter-related bloodstream infections among acute-care hospitals reporting at the VINCat program (Infection Control and Antimicrobial Stewardship Catalan Program) from 2008 to 2018. Methods: Data on 55 hospitals in Catalonia reporting all the episodes of CRBSI diagnosed according to standardized definitions during 2008–2018 were used for the analysis. Participating hospitals were classified into 3 groups according to size: group 1 (>500 beds), 9 hospitals; group 2 (500–200 beds), 17 hospitals; and group 3 (<200 beds), 29 hospitals. Catheters were classified in 3 categories: CVCs, PICVCs, and short peripheral venous catheters (PVCs). Rates of catheter-related bloodstream infection (CR-BSI) were obtained by adjusting the total number of episodes by 1,000 hospital stays. Simple linear regressions were performed. Values of P ≤ .05 were considered statistically significant. Results: During the study period, 8,221 nosocomial episodes of CRBSI were diagnosed among the 55 participating hospitals. In total, 37,587,967 hospital stays were counted. The CRBSI rate was 0.22 episodes per 1,000 hospital stays (group 1, 0.28; group 2, 0.15; and group 3, 0.16), following a downward trend from 2008 to 2018 from 0.28 to 0.21 per 1,000 hospital stays ( P < .005). Among them, CVC-BSI showed a downward trend (from 610 annual episodes in 2008 to 312 in 2018), and PICVC and PVC showed an upward trend (from 51 and 120 annual episodes in 2008 to 130 and 312 in 2018, respectively). Annual rates of PICVCs and PVCs showed an upward trend, but CVCs showed a downward trend in 2018 ( P < .05): 0.09 per 1,000 hospital stays for PICVCs; 0.07 per 1,000 hospital stays for PVCs, and 0.04 episodes per 1,000 hospital stays for CVCs (Fig. 1). Conclusions: PIVC-related bloodstream infections have increased in recent years, whereas bloodstream infections related to CVC have followed a downward trend. Our hospitals should implement preventive measures to specially address the prevention of PICVC infections. Funding: None Disclosures: None

Background Healthcare-associated infections caused by Pseudomonas aeruginosa are associated with poor outcomes. However, the role of P. aeruginosa in surgical site infections after colorectal surgery has not been evaluated. The aim of this study was to determine the predictive factors and outcomes of surgical site infections caused by P. aeruginosa after colorectal surgery, with special emphasis on the role of preoperative oral antibiotic prophylaxis. Methods We conducted an observational, multicenter, prospective cohort study of all patients undergoing elective colorectal surgery at 10 Spanish hospitals (2011–2014). A logistic regression model was used to identify predictive factors for P. aeruginosa surgical site infections. Results Out of 3701 patients, 669 (18.1%) developed surgical site infections, and 62 (9.3%) of these were due to P. aeruginosa . The following factors were found to differentiate between P. aeruginosa surgical site infections and those caused by other microorganisms: American Society of Anesthesiologists’ score III–IV (67.7% vs 45.5%, p  = 0.001, odds ratio (OR) 2.5, 95% confidence interval (95% CI) 1.44–4.39), National Nosocomial Infections Surveillance risk index 1–2 (74.2% vs 44.2%, p  < 0.001, OR 3.6, 95% CI 2.01–6.56), duration of surgery ≥75thpercentile (61.3% vs 41.4%, p  = 0.003, OR 2.2, 95% CI 1.31–3.83) and oral antibiotic prophylaxis (17.7% vs 33.6%, p  = 0.01, OR 0.4, 95% CI 0.21–0.83). Patients with P. aeruginosa surgical site infections were administered antibiotic treatment for a longer duration (median 17 days [interquartile range (IQR) 10–24] vs 13d [IQR 8–20], p  = 0.015, OR 1.1, 95% CI 1.00–1.12), had a higher treatment failure rate (30.6% vs 20.8%, p  = 0.07, OR 1.7, 95% CI 0.96–2.99), and longer hospitalization (median 22 days [IQR 15–42] vs 19d [IQR 12–28], p  = 0.02, OR 1.1, 95% CI 1.00–1.17) than those with surgical site infections due to other microorganisms. Independent predictive factors associated with P. aeruginosa surgical site infections were the National Nosocomial Infections Surveillance risk index 1–2 (OR 2.3, 95% CI 1.03–5.40) and the use of oral antibiotic prophylaxis (OR 0.4, 95% CI 0.23–0.90). Conclusions We observed that surgical site infections due to P. aeruginosa are associated with a higher National Nosocomial Infections Surveillance risk index, poor outcomes, and lack of preoperative oral antibiotic prophylaxis. These findings can aid in establishing specific preventive measures and appropriate empirical antibiotic treatment.

We prospectively studied 485 episodes of bacteremia in neutropenic patients with cancer. Viridans streptococci caused a total of 88 episodes (18%). Ten (11%) of these 88 cases were associated with serious complications: acute respiratory distress syndrome (ARDS) plus septic shock (5 cases), ARDS (3), and septic shock (2). Streptococcus mitis was the species most frequently isolated (7 of 10 episodes). Four viridans streptococci showed a diminished susceptibility to penicillin (MICs ranged from 0.25 to 4 µg/mL), and 5 strains were resistant to ceftazidime (MICs ranged from 2 to >32 µg/mL). Patients with viridans streptococcal bacteremia (VSB) who developed serious complications were compared with patients with VSB without complications. Severe oral mucositis (70% vs. 32.5%, respectively; P = .036), high-dose chemotherapy with cyclophosphamide (60% vs. 25%, respectively; P = .043), and allogeneic bone marrow transplantation (40% vs. 10%, respectively; P = .040) were the only variables found to be significantly associated with the development of complications. Neither a specific species of viridans streptococci nor resistance to penicillin was associated with the occurrence of complications. The mortality rate was higher in case patients than in control patients (80% vs. 17.5%, respectively; P < .001). Serious complications associated with VSB occur mainly in patients receiving high-dose chemotherapy with cyclophosphamide before allogeneic bone marrow transplantation who develop severe oral mucositis; these complications are associated with a high mortality rate.

We identified 17 cases of pneumococcal bacteremia among 340 neutropenic cancer patients with bacteremia. Pneumonia was more frequent in patients with pneumococcal bacteremia than in those with bacteremia due to other organisms: 12 (71%) of 17 patients with pneumococcal bacteremia had pneumonia, whereas only 23 (7%) of 323 patients with nonpneumococcal bacteremia had pneumonia (P < .001). Eight (47%) of the 17 episodes of pneumococcal bacteremia were caused by penicillin-resistant strains (MICs ranged from 0.12 μg/mL to 4 μg/mL); these penicillin-resistant pneumococci showed varying degrees of diminished susceptibility to all 13-lactams studied, especially ceftazidime (MICs of this drug ranged from 1 μg/mL to 64 μg/mL). Imipenem was the β-lactam agent most active against these organisms (MICs ranged from 0.03 μg/mL to 0.25 μg/mL). Patients with penicillin-resistant pneumococcal bacteremia received inappropriate empirical antibiotic therapy more often than did patients with bacteremia due to susceptible strains (i.e., 4 (50%) of 8 patients vs. 0 of 9, respectively; P < .05). Eight (47%) of the 17 patients with pneumococcal bacteremia died. In areas where penicillin-resistant pneumococci are highly endemic, these findings should be considered in selecting empirical antibiotic therapy for neutropenic patients with cancer who are suspected of having pneumonia.

Listeriosis in HIV infected patients is uncommon and usually presents as meningitis or bacteraemia. Pleural fluid infections caused by this organism are extremely rare. A case is described of empyema caused by Listeria monocytogenes in an HIV infected patient that was successfully treated with medical treatment only.

The European Union (EU) aims for a tobacco use prevalence of less than 5% by 2040 with its Tobacco-Free Generation goal, aligning with the tobacco endgame approach. In the Joint Action on Tobacco Control 2 (JATC-2) -project, we examined adopted and planned endgame goals and measures as well as preparedness to counter tobacco industry interference in the process. We surveyed key informants in 24 out of 50 countries in the WHO European Region (19 of the 27 EU Member States, MS). Altogether, eight countries (7 EU MS) had official governmental endgame goals, and an additional six EU MS had similar proposals from government, civil society or research entities. Movement towards tobacco endgame was most evident in retail-oriented and consumer-oriented policies. These include restricting the sales of tobacco and related products and raising the age limit above 18 years. Product standards were used especially to regulate flavours but no measures to substantially reduce addictiveness were reported. Market-oriented measures that tap into industry profits were predominantly missing, and countries often lacked concrete tools to prevent industry interference. Respondents’ concerns around tobacco endgame were related to high smoking prevalence in some population groups, non-combustible and new nicotine products, cross-border marketing, political will, challenges with the existing regulations and industry interference. Results indicate both momentum and challenges in adopting and disseminating measures that facilitate achieving tobacco endgame goals. The EU goal can be used to advocate for national endgame goals and measures, and for the strengthened implementation of the WHO Framework Convention on Tobacco Control.
