Abstract Introduction Pediatric cancer patients merit the placement of central lines for the treatments they receive. Subcutaneous central ports (SCs) and peripherally inserted central catheters (PICCs) are the most frequently used lines. PICCs have gained popularity due to the ease of insertion, which can be invaluable in the pediatric oncology setting for administration of intravenous therapy, parenteral nutrition, and/or blood products. Since central-line-associated bloodstream infections increase the morbidity and mortality of cancer patients, as well as increase the cost generated by their treatment, active surveillance of these healthcare-associated infections is warranted. Methods This is a retrospective descriptive study of pediatric patients treated via PICCs at the Hospital SOLCA Núcleo Quito between 2009 and 2019. Results During the study period, 70 PICC lines were placed in 66 patients, totaling 1862 catheter-days. The majority of patients (75.7%) were diagnosed with leukemia or lymphoma. As of 2011, all PICCs were placed in the operating room by a surgeon. Ultrasound was used 39 times for the insertion of PICCs. Inadequate peripheral venous access was the most common indication (64.2%) for placement. Twenty-nine PICCs had complications, of which 13 were infectious complications and 16 were noninfectious. The most common infectious complication was PICC-related bloodstream infection (13), and the most frequent noninfectious complication was occlusion (10). The overall complication rate was 15.5 complications per 1000 catheter-days, and the overall infectious complication rate was 6.9 complications per 1000 catheter days. Annual complication rates fluctuated over the study period. The PICC line-associated infection rate per 1000 catheter-days was 13.1‰ in 2009, 12.4‰ in 2010, 5.0‰ in 2011, 7.9‰ in 2012, 0 in 2013, 13.4‰ in 2014, 4.8‰ in 2015, 16.2‰ in 2016, 8.2‰ in 2017, and 4.3‰ in 2018. Conclusion In general, complications related to PICC in pediatric patients at a tertiary care oncology hospital have fluctuated over the years. Our findings indicate the need for further efforts in staff education and training in the insertion, care, and maintenance of PICC lines. Best practice guidelines are also critical to reducing complications, especially occlusion and infection rates, to thereby improve patient outcomes.

Abstract Background Infectious processes are frequent complications presented in pediatric patients with cancer. Currently, the indiscriminate use of antibiotics induces resistance to available treatments, creating the emergence of multi-drug-resistant organisms (MDROs). Due to the impact in morbidity and mortality secondary to MDRO infection, we aimed to identify risk factors associated with mortality in infections due to MDROs in pediatric patients with cancer. Methods Case–control study nested in a prospective cohort of pediatric oncology patients with febrile neutropenia (FN) at Hospital Infantil de México Federico Gómez (HIMFG) in Mexico City from March 2015 to September 2017. MDRO was defined as acquired non-susceptibility to at least one agent in three or more antimicrobial categories. Patients with FN episodes who died from an infection due to MDROs were defined as cases and patients with FN episodes of an infection due to MDROs who did not die were defined as controls. Mucositis, septic shock, PICU stay, and bacterial prophylaxis (Trimethoprim/Sulfamethoxazole) were compared between groups. Descriptive statistics was performed and Pearson χ 2 or Student’s t-test were used to compare risk factors between groups. Results A total of 929 FN episodes were documented, 44.4% episodes occurred in male patients, mean age was 7.9 years, with the population under 5 years being the most represented (68.2%). The most frequent diagnosis was acute lymphoblastic leukemia in 75% followed by rhabdomyosarcoma in 10.5% and acute myeloid leukemia in 9.6%. Prophylaxis (trimethoprim/sulfamethoxazole) was used in 86%, mucositis was present in 9.2% of episodes. 12.1% had septic shock and 4.7% were admitted to PICU. In 148 FN episodes (15.9%) a microorganism was identified, of these 50 (33.7%) were due to an MDROs. Urinary tract infection was the most frequent site (49%), followed by bloodstream infections (47%). K. pneumoniae was the most frequent MDRO in 22.8%, followed by E. coli in 19.2% and P. aeruginosa in 14%. Septic shock was presented in 26% of MDROs infections. Overall mortality was 1.94% and only 0.86% (8) were secondary to MDROs. Of patients with MDRO isolated mortality was 30% (15/50). Mortality associated with bloodstream infection due to MDROs was 25% compared with other source of MDROs infections (3%) (P = 0.01). Septic shock was present in 40% of patients with death due to MDROs infection (P = 0.001). Conclusions In our population of children with FN episodes who had an isolated microorganism, infection due to MDROs are high (33.7%) and MDROs infection-directed mortality was as high as 30%. Bloodstream infections and septic shock were risk factors associated with mortality due to MDROs.

BACKGROUND Guidelines for treatment of central line–associated bloodstream infection (CLABSI) recommend removing central venous catheters (CVCs) in many cases. Clinicians must balance these recommendations with the difficulty of obtaining alternate access and subjecting patients to additional procedures. In this study, we evaluated CVC salvage in pediatric patients with ambulatory CLABSI and associated risk factors for treatment failure. METHODS This study was a secondary analysis of 466 ambulatory CLABSIs in patients <22 years old who presented to 5 pediatric medical centers from 2010 to 2015. We defined attempted CVC salvage as a CVC left in place ≥3 days after a positive blood culture result. Salvage failure was removal of the CVC ≥3 days after CLABSI. Successful salvage was treatment of CLABSI without removal of the CVC. Bivariate and multivariable logistic regression analyses were used to test associations between risk factors and attempted and successful salvage. RESULTS A total of 460 ambulatory CLABSIs were included in our analysis. CVC salvage was attempted in 379 (82.3%) cases. Underlying diagnosis, CVC type, number of lumens, and absence of candidemia were associated with attempted salvage. Salvage was successful in 287 (75.7%) attempted cases. Underlying diagnosis, CVC type, number of lumens, and absence of candidemia were associated with successful salvage. In patients with malignancy, neutropenia within 30 days before CLABSI was significantly associated with both attempted salvage and successful salvage. CONCLUSIONS CVC salvage was often attempted and was frequently successful in ambulatory pediatric patients presenting with CLABSI.

ABSTRACT Anaerobes are an important but uncommon cause of bloodstream infections (BSIs). For pediatric patients, routine inclusion of an anaerobic blood culture alongside the aerobic remains controversial. We implemented automatic anaerobic blood culture alongside aerobic blood cultures in a pediatric emergency department (ED) and sought to determine changes in recovery of obligate and facultative anaerobes. This was a cohort study in a pediatric ED (August 2015 to July 2018) that began in February 2017. Blood culture positivity results for true pathogens and contaminants were assessed, along with a secondary outcome of time to positivity (TTP) of blood culture. A total of 14,180 blood cultures (5,202 preimplementation and 8,978 postimplementation) were collected, with 8.8% (456) and 7.1% (635) positive cultures in the pre- and postimplementation phases, respectively. Of 635 positive cultures in the postimplementation phase, aerobic blood cultures recovered 7.6% (349/4,615), whereas anaerobic blood cultures recovered 6.6% (286/4,363). In 211/421 (50.0%) paired blood cultures, an organism was recovered in both cultures. The number of cases where organisms were only recovered from an aerobic or an anaerobic bottle in the paired cultures were 126 (30.0%) and 84 (20.0%), respectively. The TTP was comparable regardless of bottle type. Recovery of true pathogens from blood cultures was approximately 7 h faster than recovery of contaminants. Although inclusion of anaerobic blood cultures only recovered 2 (0.69%) obligate anaerobes, it did allow for recovery of clinically significant pathogens that were negative in aerobic blood cultures and supports the routine collection of both bottles in pediatric patients with a concern of bloodstream infections.

Abstract Background: Advances in medical technology have allowed pediatric patients to be discharged home with complex devices, including central venous catheters (CVCs). For these patients to be safely discharged, families require training to care for these catheters. At a large children's hospital, extensive family education and training for CVCs was already established. However, community caregivers were not receiving the same training. In an effort to target these caregivers, an education program was designed and implemented in 2011. Methods: The program was originally designed and implemented by nurses on a gastroenterology unit and has expanded to include instructors from the vascular access team, hematology/oncology department, and pulmonary department. All community nurses providing care for pediatric patients in the region are welcome to attend the free class with education hours offered. The class is structured with lecture time and skills practice through simulation. Results: Since the program began in 2011, 34 classes have been offered and 305 nurses have attended from multiple home health companies and school districts in the region. Community-acquired central line-associated bloodstream infection (CLABSI) rates for the pediatric gastroenterology and oncology patient populations have decreased significantly since the class began. Conclusions: An education program targeting nurses in the community who care for complex patients with CVCs can decrease community-acquired infection rates and complications. This program can be designed and tailored for multiple patient populations with varying complexities and medical devices.

Background:Stenotrophomonas maltophilia (S. maltophilia) is an opportunistic and nosocomial pathogen that can cause an invasive and fatal infection, particularly in hospitalized and immunocompromised patients. However, little is known about the impact of S. maltophilia bacteremia in pediatric patients. Therefore, we aimed to identify risk factors for mortality, antibiotic susceptibility of S. maltophilia, and mortality rates in pediatric patients with S. maltophilia bacteremia. Methods: We conducted a retrospective cohort study by identifying all S. maltophilia–positive blood cultures in the microbiology laboratory database between January 2007 and December 2018 from hospitalized pediatric patients (age, 1–14 years) at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia. After identifying patients with S. maltophilia bacteremia, medical charts were reviewed for demographics, clinical data, and outcome within 7 days of bacteremia diagnosis. Risk factors associated with mortality in S. maltophilia bacteremia patients were determined using univariate and multivariate analyses. Results: Overall, 68% of pediatric patients with S. maltophilia bacteremia were identified. The most common underlying primary diagnoses were malignancy (29.4%), congenital heart diseases (16.2%), anemia (14.7%), and primary immunodeficiency (11.8%). All infections were nosocomial infections, and (88.2%) bacteremia cases were central-line–associated bloodstream infections. The risk factors associated with mortality as determined by univariate analysis were ICU admission (P < .001), intubation (P = .001), neutropenia (P = .008), prior use of carbapenem (P = .002), thrombocytopenia (P = .006), and respiratory colonization (P < .001). On multivariate analysis, ICU admission (P = .007; 95% CI, 0.003–0.406) and neutropenia (P = .009; 95% CI, 0.013–0.537) were the major risk factors associated with mortality. S. maltophilia was the most susceptible to trimethoprim and sulfamethoxazole (TMP/SMX, 94.1%), followed by levofloxacin (85.7%). In addition, 36 patients received TMP/SMX as monotherapy, and 11 patients received it in combination with other antibiotics (fluoroquinolone, ceftazidime, or aminoglycoside). Hence, no statistically significant difference was observed in patient mortality. The overall mortality rate within 7 days of S. maltophilia bacteremia diagnosis was 33.8%. Conclusions:S. maltophilia bacteremia is a devastating emerging infection associated with high mortality among hospitalized children. Therefore, early diagnosis and prompt management based on local susceptibility data are crucial. Various risk factors, especially ICU admission and neutropenia, are associated with S. maltophilia bacteremia mortality.Funding: NoneDisclosures: None
