Abstract
In recent years, the incidence and drug resistance of Candida parapsilosis have increased. Our study aimed to determine the antifungal sensitivity of C. parapsilosis and the clinical and demographic characteristics of children with candidemia. Two hundred pediatric patients with C. parapsilosis candidemia were included in the study between 1 January 2010 and 1 August 2023. Clinical samples were evaluated on a BACTEC-FX-40 automatic blood culture device (Becton Dickinson, USA). Yeast isolates were identified to the species level via identification cards (YST) using the VITEK 2 Compact (bioMeriéux, France) system. Antifungal susceptibility was performed using antifungal cell cards (AST-YST01). Approval for the study was received from the "University Faculty of Medicine" Hospital Clinical Research Ethics Committee. Non-catheter candidemia was detected in 127 (63.5%) patients, and catheter-related candidemia was detected in 73 (36.5%) patients. It was observed that the patients' history of malignancy, mechanical ventilation, urinary catheter, nasogastric tube, and intensive care unit stay was associated with C. parapsilosis mortality. The mortality rate from candidemia was 9.5%. The most frequently preferred antifungal agents were amphotericin B and fluconazole. The fluconazole drug resistance rate was found to be 6%, and the amphotericin B drug resistance rate was 4%. Because C. parapsilosis candidemia mortality rates can be high depending on risk factors and clinical characteristics, it is important to initiate appropriate and timely antifungal therapy. We think that our study can provide important information about the clinical profiles, distributions, susceptibility profiles, and control of antifungal resistance of C. parapsilosis isolates. IMPORTANCE It has been observed that the frequency and antifungal resistance of Candida parapsilosis have increased recently. In our study, we aimed to determine the antifungal sensitivity of C. parapsilosis and the clinical and demographic characteristics of children with candidemia. It was observed that the patients' history of malignancy, mechanical ventilation, urinary catheter, nasogastric tube, and intensive care stay was associated with C. parapsilosis mortality. The mortality rate from candidemia was 9.5%. The most frequently preferred antifungal agents were amphotericin B and fluconazole. The fluconazole drug resistance rate was found to be 6%, and the amphotericin B drug resistance rate was 4%. Because C. parapsilosis candidemia mortality rates can be high depending on risk factors and clinical characteristics, it is important to initiate appropriate and timely antifungal therapy.

Central Venous Catheter-related Bloodstream Infections Caused by Enterobacterales in Pediatric Oncology Patients: Catheter Salvage or Removal. Pediatr Infect Dis J 2024; 43:49-55. [PMID: 37983368 PMCID: PMC10723766 DOI: 10.1097/inf.0000000000004106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 08/24/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND The aim was to determine whether salvage treatment with systemic antibiotics is a safe and effective strategy for Enterobacterales bloodstream infections (BSI) in pediatric oncology patients with a central venous catheter (CVC). METHODS A retrospective study was performed on oncology and stem cell recipient patients with a CVC and blood culture with Enterobacterales , at the Princess Máxima Centre for Pediatric Oncology, Utrecht, the Netherlands. Analyses were performed for all BSI and for episodes meeting central line-associated bloodstream infection (CLABSI) criteria. The cumulative incidence of an event (ie, removal, intensive care admission or death) was estimated after blood culture collection for episodes primarily treated with antibiotics. The effect of prognostic factors on the hazard of the event of interest was assessed by estimating a Cox proportional hazard regression model. RESULTS In total, 95 CVC-related Enterobacterales BSIs in 82 patients were included; 12 (13%) BSIs required immediate CVC removal and for 83 (87%) BSIs CVC salvage was attempted. The cumulative incidence of events at 60 days was 53.0% [95% confidence interval (CI): 41.7-63.1] for BSIs (n = 83), and 64.4% (95% CI: 48.3-76.7) for CLABSIs (n = 45). The events occurred after a median of 6 (Q1-Q3: 2-15) and 6 (Q1-Q3: 2-20) days for BSIs and CLABSIs, respectively. Intensive care admission after salvage treatment was required in 16% of the BSIs and CLABSIs, resulting in death in 5% and 2% of cases, respectively. No significant association between risk factors and events was found. CONCLUSIONS The cumulative incidence of an event at 60 days after salvage treatment for Enterobacterales CLABSIs and BSIs in pediatric oncology patients is high. Immediate CVC removal appears recommendable for this patient group.

Outcomes in Pediatric Central Line-associated Bloodstream Infections Treated With Antimicrobial Locks: A 14-year Retrospective Analysis. Pediatr Infect Dis J 2023; 42:473-478.

Abstract
BACKGROUND Central line-associated bloodstream infections (CLABSI) are the most common healthcare-associated infection in children. Antimicrobial lock therapy (ALT) is a recommended component of CLABSI treatment; however, studies characterizing pediatric ALT-based CLABSI therapy are few. METHODS All CLABSI treated with ALT at a single tertiary-care pediatric hospital for years 2004-2018 were identified by retrospective chart review and demographic, clinical, microbiological and pharmacy data were extracted. Three clinical outcomes were defined: CLABSI clearance, central venous catheter (CVC) removal and infection recurrence. Factors associated with these outcomes were examined and patterns in pathogen occurrence were described. RESULTS During the study period, 1188 CLABSI treated with ALT were identified. In all, 969 (85%) CLABSI initially cleared. In the CLABSI with initial clearance, CVCs were retained a median of 63 days after infection onset, and 20% recurred. Skin-colonizing microbes (Staphylococcus aureus, coagulase-negative Staphylococci) were more likely to produce monomicrobial infections, whereas bowel-colonizing microbes (Escherichia coli, Enterococci) were more associated with polymicrobial infections. In a multivariate model, infection history, resistant pathogens and CVC type were strongly correlated with infection recurrence, whereas bone marrow transplant status, neutrophil count and line type were correlated with CVC removal. CONCLUSIONS Optimal therapeutic approaches to pediatric CLABSI remain uncertain, including the utility of ALT. Prior reports of ALT use in children have been smaller in size and largely described hematology-oncology or hemodialysis populations. We describe trends in pediatric CLABSI, including efficacy among solid organ transplant recipients and children with short-gut syndrome. These data provide guidance on selecting CLABSI for optimal ALT use.

Abstract
BACKGROUND Burkholderia cepacia complex (BCC) represents a group of multidrug-resistant gram-negative bacteria that cause infections among immunocompromised hosts. Bacteremia occurs in patients who are chronically ill and is associated with substantial morbidity and mortality. The aim of this study was to investigate the clinical characteristics and outcomes of BCC bacteremic patients without cystic fibrosis. METHODS We conducted a retrospective study at the National Taiwan University Hospital. Adults with BCC bacteremia from January 2015 to May 2019 were enrolled. The primary outcome was 14-day mortality. Multivariable logistic regression was performed for outcome analysis. RESULTS One-hundred and ninety-five patients were analyzed and their mean age was 67 years. Over 95% of the BCC isolates were susceptible to trimethoprim/sulfomethoxazole (TMP/SXT). Levofloxacin resistance rates were high, with only 25.1% of isolates being susceptible. Pairwise comparisons were made between different definitive regimens including meropenem-monotherapy, ceftazidime-monotherapy, levofloxacin-monotherapy, TMP/SXT-monotherapy, tigecycline-monotherapy as well as combination versus monotherapy. No regimen was significantly associated with survival in our study. Multivariable logistic regression showed that the Pitt bacteremia score (adjust odds ratio [aOR],1.46; 95% confidence interval [CI],1.19-1.79; p < 0.001), underlying metastatic cancer (aOR, 2.73; 95% CI, 1.01-7.39; p = 0.047), inappropriate definitive treatment independently predicted greater 14-day mortality (aOR, 8.21; 95% CI, 2.49-27.08; p < 0.001). CONCLUSIONS No single regimen is associated with improved mortality. After adjusting for other potential confounders, our data suggest selection of an appropriate antibiotic provide better clinical outcomes among patients with BCC bacteremia.

Abstract
BACKGROUND Optimal management of Central Venous Catheter related, or associated, bloodstream infections (CRBSI or CLABSI) in children is not established. OBJECTIVE To evaluate successful of catheter salvage strategies in pediatric patients. METHODS Studies retrieved from medical databases and article reference lists. Data were collected relating to clinical outcomes of 2 treatments: systemic antibiotics alone or in association with antimicrobial lock therapy (ALT). 95% CIs and OR were calculated from a mixed logistic effects model. Heterogeneity was summarized using I2 statistics. Publication bias was investigated by Egger's regression test and funnel plots. RESULTS From 345 identified publications, 19 met inclusion criteria (total of 914 attempted salvage strategies. To achieve successful catheter salvage, in CRBSI the addition of ALT was superior to systemic antibiotics alone (OR -0.40, 95%CI -1.41 - 0.62): 77% (95%CI 69-85, I2=42.5%, p=0.12) and 68% of success (95%CI 59-77, I2=0, p<0.05), respectively. CRBSI recurrence was less common in studies that used ALT compared with systemic antibiotics alone: 5% (95%CI 0-13, I2=59.7%; p=0.03) and 18% of recurrence (95%CI, 9-28, I2=0, p< 0.05), respectively. Recurrences were low with both antibiotic-locks and ethanol-lock. No clear benefits of ALT addition compared to systemic antibiotic only was found in CLABSI (OR -0.81, 95% CI -0.80 - 2.43). CONCLUSIONS The addition of an antimicrobial lock solution to systemic antibiotic may be beneficial for successful catheter salvage in pediatric patients with CRBSI, depending on etiology, whilst no statistically significant difference between systemic antibiotic with or without addition of an antimicrobial lock solution was found regarding CLABSI.

Abstract
Patients with underlying hematologic malignancy (HM) and/or allogeneic hematopoietic stem cell transplant (HCT) recipients are at risk for mucosal barrier injury laboratory-confirmed bloodstream infection (MBI-LCBI) secondary to bacterial translocation. There is sparse data comparing MBI-LCBI management practices, in particular central venous catheter (CVC) salvage versus removal. We created a 22-item poll of Infectious Disease specialists at major US cancer centers on management controversies. Response rate was 44% (31/70). CVC salvage was a common practice among 87.5%. This was followed by a single center retrospective study (2017-2019) comparing outcomes related to CVC practices. We identified 115 patients, 52% (60/115) admitted for chemotherapy and 33% (38/115) for allogeneic HCT. The majority of patients (78%, 90/115) had their CVC removed. There was no difference in 72 h defervescence, microbiological clearance, in-hospital mortality, and 90-day recurrent infection between CVC salvage versus removal. CVC salvage is a safe approach in certain clinical scenarios.

Abstract
BACKGROUD/PURPOSE Bloodstream infections (BSI) are common in patients with major burns, but its effect on mortality remains controversial. This study was aimed to investigate if BSI is significant risk factor of mortality? METHODS This is a retrospective chart review study included 266 adult patients admitted to our burn center from 2000 to 2019. Age, sex, inhalation injuries, total burn surface area (TBSA), duration of stay in intensive care unit, BSI and mortality were variables studied. Fisher exact test, Mann-Whitney test and logistic regression was used for statistical analysis. RESULTS There were 234 survivors and 32 non-survivors. Male was predominant. The overall incidence of BSI was 18.8%, and the overall crude mortality was 12%. Burns ≥30% TBSA and BSI were significant risk factors. A predictive function based on30% TBSA and BSI within 14 days after the onset of burns (BSI-14) was derived. The function has a sensitivity of 0.97, specificity of 0.42 and achieved a maximum Youden Index at functional value ≥0.05727. The mortality probability of BSI-14 in burns ≥30% TBSA was 40.8%. CONCLUSIONS BSI and burns ≥30% TBSA were significant risk factors of mortality. Early detection of BSI-14 is critical in burn care as its probability of mortality can be as high as 40% in patients ≥30% TBSA of burns. To reduce the risk of mortality, early in ventilator withdrawal, invasive lines and tubes removal, and early grafting should be emphasized besides infection control and appropriate use of antibiotics.

Abstract
OBJECTIVE The majority of the children with a central line who present to the emergency department with fever or other signs of bacteremia do not have a central line-associated bloodstream infection (CLABSI). Our objective was to develop a clinical prediction model for CLABSI among this group of children in order to ultimately limit unnecessary hospital admissions and antibiotic use. METHODS We performed a nested case-control study of children with a central line who presented to the emergency department of an urban, tertiary care children's hospital between January 2010 and March 2015 and were evaluated for CLABSI with a blood culture. RESULTS The final multivariable model developed to predict CLABSI consisted of 12 factors: age younger than 5 years, black race, use of total parenteral nutrition, tunneled central venous catheter, double-lumen catheter, absence of other bacterial infection, absence of viral upper respiratory tract infection symptoms, diarrhea, emergency department temperature greater than 39.5°C, fever prior to presentation, neutropenia, and spring/summer season. The clinical prediction score had good discrimination for CLABSI with a c-statistic of 0.81 (confidence interval, 0.77-0.85). A cut point less than 6 was associated with a sensitivity of 98.5% and a negative predictive value of 99.2% for CLABSI. CONCLUSIONS We were able to identify risk factors and develop a clinical prediction model for CLABSI in children presenting to the emergency department. Once validated in future study, this clinical prediction model could be used to assess the need for hospitalization and/or antibiotics among this group of patients.

Abstract
A frequent complication of central venous port systems (CVP) is infection (CVP-I), either local (CVP-LI) or a life-threatening blood stream infection (CVP-BSI). We examined the course of CVP-I including results of an antibiotic eradication attempt of CVP-BSI. We investigated adults with CVP-I from 2010 to 2018 who had to undergo port explantation or were treated by a combination of systemic antibiotics and antibiotic lock therapy (ALT). In nine years we diagnosed 206 CVP-I (CVP-LI: 52; CVP-BSI: 152). In 146 patients with CVP-I the port system was primary explanted, while 56 patients received antibiotics/ALT. 79% of Gram negative pathogens and 50% of coagulase negative staphylococci (CoNS) were eradicated. Failure of antibiotic treatment was more often associated with short time span since CVP implantation, neutropenia and polymicrobial infection. All patients with non-neoplastic disease survived, while 18/173 patients (10%) with underlying malignant disease had a fatal outcome in the same hospital stay.

Abstract
Patients with pediatric cancer face an increased risk of infections. In most cases, these infections are associated with the use of a long-term central venous catheter. This study describes the epidemiology of a port-associated bacteremia as well as a profile of microorganisms responsible for port-associated bloodstream infections (PABSIs) in pediatric patients with cancer treated in a single center. The retrospective analysis included patients with cancer who had implanted a port, hospitalized between 2010 and 2015 at the Department of Pediatric Oncology, Hematology and Bone Marrow Transplantation, Poznan University of Medical Sciences. The medical records of patients were reviewed for demographic characteristics, diagnosis, port-related complications, and their management. Data were collected from patients' electronic medical records containing complete information on medical examinations and supplementary tests, diagnosis, timing, and type of port-associated complications. In a study period, 277 ports were inserted to 241 patients. A total of 183 094 catheter days were analyzed. Sixteen patients had more than 1 insertion of a port. The commonest observed complication was PABSI (40.07%) and the incidence density was 0.6 per 1000 port-days. Staphylococcus was the most commonly isolated organisms from patients with PABSI. From all port-associated complications, bloodstream infections and mechanical complications were the most often observed complications. The commonest pathogens responsible for PABSI were coagulase-negative staphylococci. Pathogens resistant to standard antibiotic treatment play an important role in PABSI, with methicillin-resistant Staphylococcus epidermidis being the predominant pathogen. Port-associated bloodstream infections are a common reason for preterm removal of a port.

AIM Central line-associated bloodstream infection associated bloodstream infection (CLABSI) is a serious complication of patients on central venous catheters (CVC). Taurolidine-citrate solution (TCS) is a catheter-lock solution with broad-spectrum antimicrobial action. This study's aim was to evaluate the efficacy of TCS in reducing CLABSI rates in paediatric haematology-oncology (H/O) and gastrointestinal (GI) patients with long-term CVC. METHODS This was an open-label trial of H/O and GI inpatients with the following inclusion criteria: <17 years old, more than or equal to one previous CLABSI and a minimum TCS dwell time of ≥8 h. CLABSI per 1000 catheter-days was calculated from each patient's first CVC insertion till 14 December 2017 or until TCS discontinuation. RESULTS Thirty-three patients were recruited with a median age of 3.5 years; H/O and GI constituted 60.6 and 39.4% respectively. CVC types were Hickman line (45.5%), implantable port (24.2%) and peripherally inserted central catheter (30.3%). Mean pre- and post-TCS CLABSI rates per 1000 catheter-days were 14.44 and 2.45 (P < 0.001) for all patients; 16.55 and 2.81 for H/O patients; and 11.21 and 1.90 for GI patients, respectively. Pre- and post-TCS rate ratio was 0.20, 0.10 and 0.30 for all, H/O and GI patients, respectively (P < 0.001). TCS also led to a reduction in CVC removal from 66.7 to 9.09% (P < 0.001). CONCLUSIONS TCS usage was highly successful in CLABSI reduction by 80% in all patients, 90% in H/O and 70% in GI patients. In patients with high baseline CLABSI rates, TCS is an effective catheter-lock therapy to reduce CLABSI rates in paediatric patients.

A 1-year survey of catheter-related infections in a pediatric university hospital: A prospective study. Arch Pediatr 2019; 27:79-86. [PMID: 31791827 DOI: 10.1016/j.arcped.2019.11.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2018] [Revised: 10/10/2019] [Accepted: 11/11/2019] [Indexed: 12/21/2022]
Abstract
BACKGROUND Central venous catheters (CVCs) provide a great comfort for hospitalized children. However, CVCs increase the risk of severe infection. As there are few data regarding pediatric epidemiology of catheter-related infections (CRIs), the main objective of this study was to measure the incidence rate of CRIs in our pediatric university hospital. We also sought to characterize the CRIs and to identify risk factors. MATERIALS AND METHODS We conducted an epidemiological prospective monocentric study including all CVCs, except Port-a-Caths and arterial catheters, inserted in children from birth to 18 years of age between April 2015 and March 2016 in the pediatric University Hospital of Nantes. Our main focus was the incidence rate of CRIs, defined according to French guidelines, while distinguishing between bloodstream infections (CRBIs) and non-bloodstream infections (CRIWBs). The incidence rate was also described for each pediatric ward. We analyzed the association between infection and potential risk factors using univariate and multivariate analysis by Cox regression. RESULTS We included 793 CVCs with 60 CRBIs and four CRIWBs. The incidence rate was 4.6/1000 catheter-days, with the highest incidence rate occurring in the neonatal intensive care unit (13.7/1000 catheter-days). Coagulase-negative staphylococci were responsible for 77.5% of the CRIs. Factors independently associated with a higher risk of infection in neonates were invasive ventilation and low gestational age. CONCLUSIONS The incidence of CRIs in children hospitalized in our institution appears to be higher than the typical rate of CRIs reported in the literature. This was particularly true for neonates. These results should lead us to reinforce preventive measures and antibiotic stewardship but they also raise the difficulty of diagnosing with certainty CRIs in neonates.

Abstract
Introduction Central venous catheters (CVCs) implanted in patients with malignancies may often be associated with local or central line-associated bloodstream infections (CLABSI), which are a major source of morbidity and rarely mortality, making such patients' care difficult and complicated. Materials and Methods This retrospective study is a single-centre's experience including both paediatric and adult patients with malignancy, who had a CVC inserted and were receiving care at cancer centre of our hospital over a period between January 2017 and June 2018. Results In the period from January 2017 to June 2018, 73 confirmed cases of CLABSIs among cancer patients were included in this study. The rate of CLABSIs was estimated as 2.1 episodes/1000 CVC days. Out of 73 CLABSI cases, Gram-negative bacilli were the predominant causative agents of CLABSI constituting 72.6% (n = 53/73) of isolated organisms, 21.9% (n = 16/73) of infections were caused by Gram-positive cocci while polymicrobial infections accounted for 5.4% (n = 4/73) of these cases. Conclusion Over the last 20 years, an epidemiologic shift has occurred among CLABSI in cancer patients. These findings should be considered with the development of interventions that will prevent Gram-negative CLABSI after CVC insertion. To our knowledge, this is the first study reporting data on the incidence of CLABSIs in cancer patients at tertiary care hospital from North Indian hospital.

Abstract
Central line-associated bloodstream infections (CLABSIs) are still a major cause of morbidity and mortality in pediatric hematology-oncology patients in many countries. This cross-sectional study was a retrospective review of CLABSI in inpatient pediatric hematology-oncology cases with long-term central venous catheter at the Pediatric Hematology Department from January 2013 to June 2014. Characteristics of CLABSI events in pediatric patients with hematologic malignancies and related nonmalignant hematologic conditions are documented. CLABSI developed in 61.8% (n = 21) of the 34 hospitalized patients included in the study. The CLABSI rate was 7.8 per 1,000 inpatient central venous catheter days. Coagulase-negative staphylococci was the predominant pathogen in 47.6% of the patients with CLABSI. The high rate of CLABSI requires prevention strategies to reduce CLABSI immediately. This study provides guidance in prioritizing strategies for reducing rates of infection.

Abstract
AIM This study examined the clinical characteristics of central line-associated blood stream infections occurring within 30 days after insertion versus later infections in paediatric cancer patients and the subsequent risk for premature catheter removal. METHODS This was a retrospective study of children aged 0-18 years who were diagnosed with cancer from 2013 to 2014 at the Astrid Lindgren Children Hospital, Sweden. Clinical and microbiology data for each patient were collected for 365 days after the central venous catheter (CVC) was inserted. RESULTS During the study period, 154 children received a CVC. The overall incidence of central line associated blood stream infections was 2.0 per 1000 catheter days. A total of 108 infectious episodes were identified in 44/154 (29%) patients. Of those, 15/44 children (29%) had an early infection within 30 days and alpha-haemolytic Streptococci and coagulase-negative Staphylococci dominated. Children with early infections were more likely to have a haematological malignancy and to need premature removal of the CVC due to repeated infections. CONCLUSION We observed a high prevalence of early CVC associated blood stream infection mainly in patients with haematological malignancies. Our study highlights the importance of preventive measures in reducing infections in paediatric cancer patients.

Abstract
OBJECTIVES This study was performed to investigate the epidemiology of bloodstream infection (BSI) in oncology patients at Red Cross War Memorial Children's Hospital (RCWMCH), Cape Town, with focus placed on the most common causes, complications, and antimicrobial susceptibilities in BSI. METHODS A retrospective cross-sectional study was conducted in the Haematology-Oncology Unit of RCWMCH. All positive blood cultures from RCWMCH oncology patients obtained in 2012 to 2014 were retrieved to identify cases of BSI. RESULTS Three hundred and forty-three positive cultures were identified, for 150 BSI episodes among 89 patients; 49.1% of the culture isolates were Gram-positive bacteria, 41.6% were Gram-negative bacteria, and 9.3% were fungal. Coagulase-negative Staphylococcus and viridans group Streptococcus were the most common Gram-positive isolates. Escherichia coli and Klebsiella species were the most common Gram-negative isolates. The majority of BSI episodes occurred in patients with haematological malignancies (74%), in the presence of severe neutropenia (76.4%), and were associated with chemotherapy (88%). Complications occurred in 14% of BSI. Fungal infections had the highest prevalence of complications (21.4%). Three children died during BSI, giving a case-fatality rate of 2%. CONCLUSIONS BSI in these patients was caused mainly by Gram-positive bacteria and was associated with a low case-fatality rate. These results are consistent with worldwide experience of BSI in paediatric oncology.

Abstract
The management of long-term central venous catheter (LTCVC) infections by multidrug-resistant (MDR) bacteria in cancer patient is a challenge. The objectives of this study were to analyze outcomes in cancer patients with LTCVC-associated infection, identify risks for unfavorable outcomes, and determine the impact of MDR bacteria and antibiotic lock therapy (ALT) in managing such infections. We evaluated all LTCVC-associated infections treated between January 2009 and December 2016. Infections were reported in accordance with international guidelines for catheter-related infections. The outcome measures were 30-day mortality and treatment failure. We analyzed risk factors by Cox forward-stepwise regression. We identified 296 LTCVC-associated infections; 212 (71.6%) were classified as bloodstream infections (BSIs). The most common agent was Staphylococcus aureus Forty-six (21.7%) infections were due to MDR Gram-negative bacteria. ALT was used in 62 (29.2%) patients, with a 75.9% success rate. Risk factors identified for failure of the initial treatment were having a high sequential organ failure assessment (SOFA) score at diagnosis of infection and being in palliative care; introduction of ALT at the start of treatment was identified as a protective factor. Risk factors identified for 30-day mortality after LTCVC-associated infection were a high SOFA score at diagnosis, infection with MDR bacteria, and palliative care; introduction of ALT at the start of treatment, hematological malignancies, and adherence to an institutional protocol for the management of LTCVC-associated infection were identified as protective factors. Despite the high incidence of infection with MDR bacteria, ALT improves the outcome of LTCVC-associated infection in cancer patients.

Abstract
BACKGROUND/PURPOSE This study assessed the effect of the central line bundle on the rate of central line-associated bloodstream infections (CLABSI) in intensive care units (ICUs) in Taiwan. METHODS This national study was conducted in 27 ICUs with 404 beds total, including 15 medical ICUs, 11 surgical ICUs, and one mixed ICU. The study period was divided into two phases: a pre-intervention (between June 1, 2011 and October 31, 2011) and intervention phase (between December 1, 2011 and October 31, 2012). Outcome variables, including CLABSI rates (per 1000 catheter-days) and catheter utilization rates, were measured. RESULTS The overall rate of CLABSI significantly decreased by 12.2% (p < 0.001) from 5.74 per 1000 catheter-days in the pre-intervention phase to 5.04 per 1000 catheter-days in the intervention phase. The catheter utilization rate decreased by 1.1% from 55.3% in the pre-intervention phase to 54.2% in the intervention phase. The decline in CLABSI varied significantly among hospital and ICU levels, except surgical ICUs (p = 0.59). CONCLUSIONS Implementing a multidimensional central-line bundle significantly reduced the rates of CLABSI by 12.2% in nearly all participating ICUs, except surgical ICUs.

Abstract
Hospital acquired complications (HACs) are serious problems affecting modern day healthcare institutions. It is estimated that HACs result in an approximately 10% increase in total inpatient hospital costs across US hospitals. With US hospital spending totaling nearly $900 billion per annum, the damages caused by HACs are no small matter. Early detection and prevention of HACs could greatly reduce strains on the US healthcare system and improve patient morbidity & mortality rates. Here, we describe a machine-learning model for predicting the occurrence of HACs within five distinct categories using temporal clinical data. Using our approach, we find that at least $10 billion of excessive hospital costs could be saved in the US alone, with the institution of effective preventive measures. In addition, we also identify several keystone features that demonstrate high predictive power for HACs over different time periods following patient admission. The classifiers and features analyzed in this study show high promise of being able to be used for accurate prediction of HACs in clinical settings, and furthermore provide novel insights into the contribution of various clinical factors to the risk of developing HACs as a function of healthcare system exposure.
