A Descriptive Study of the Risk Factors Associated With Catheter-Related Bloodstream Infections in the Home Parenteral Nutrition Population

Risk factors for catheter-related bloodstream infections associated with home parental nutrition in children with intestinal failure: A prospective cohort study

BACKGROUND & AIMS

Catheter-related bloodstream infection (CRBSI) is the most common, potentially life-threatening complication of long-term parenteral nutrition (PN). We prospectively assessed the incidence and risk factors for CRBSI in children receiving long-term home PN (HPN) for intestinal failure (IF) in a single IF rehabilitation center.

METHODS

Data regarding episodes and potential risk factors for CRBSI in children on HPN were prospectively recorded.

RESULTS

Forty-one of 75 children were diagnosed with CRBSI. The overall CRBSI rate was 1.61 per 1000 catheter days. The indications for HPN were gastrointestinal motility disorders in 35%, short bowel syndrome (SBS) in 28% graft versus host disease (GvHD) post bone marrow transplant in 17%, congenital enteropathy in 15%, and severe neurodevelopmental impairment in 5%. Gastrointestinal motility disorders had significantly higher CRBSI rate compared to other groups (p < 0.0005; 2.74 in motility group vs 1.54 in GvHD group vs 0.52 in congenital enteropathies vs 0.36 in SBS group vs 0.67 in severe neurodevelopmental delay). Multivariate analysis revealed that enterocutaneous distal stoma (ileostomy or colostomy) (HR 3.35 [95% CI, 1.63-6.86]; p < 0.001), age <2 years (HR 0.28 [95% CI, 0.15-0.53]; p < 0.0001), male sex (HR 2.28 [95% CI, 1.51-3.43]; p < 0.0001), non-use of taurolidine citrate lock (HR 2.70 [95% CI, 1.72-4.11]; p < 0.0001) and gastrointestinal motility disorder (HR 3.02 [95% CI, 1.81-4.91]; p < 0.001) were independent risk factors for developing CRBSI.

CONCLUSIONS

Extra care in managing PN connections and disconnections should be taken in children with an underlying gastrointestinal motility disorder, distal enterocutaneous stoma, male sex and those aged <2 years since they are at a significantly higher risk of CRBSI. Early introduction of taurolidine lock should be considered.

Risk factors for catheter-related bloodstream infections in patients with intestinal failure undergoing home parenteral nutrition: a single-center study

PURPOSE

The incidence and risk factors of catheter-related bloodstream infections (CRBSI) in patients with intestinal failure (IF) have not been established, partly because catheter management methods vary from different facilities. This study aimed to identify the risk factors and incidence rate of CRBSIs in patients with IF who were given prophylactic treatment.

METHODS

Sixteen patients with IF who required home parenteral nutrition were enrolled in this study. Prophylactic management of CRBSI included monthly ethanol lock therapy and standardized infection prevention education. The outcomes included the incidence and risk factors of CRBSI.

RESULTS

The median incidence rate of CRBSI was 1.2 per 1000 catheter days. Univariate analysis showed that the risk of developing CRBSI was significantly associated with short bowel syndrome (< 30 cm) (p = 0.016). Other relevant findings included a significant negative correlation between serum albumin and CRBSI rate (r = - 0.505, p = 0.046), and past history of mixed bacterial infections was significantly associated with increased CRBSI rate (p = 0.013).

CONCLUSION

CRBSIs can still develop despite undergoing prophylactic management. Risk factors for CRBSI include the residual intestinal length, nutritional status, and susceptibility to certain microorganisms.

Effect of anticoagulant and platelet inhibition on the risk of bacteremia among patients with acute pyelonephritis: a retrospective cohort study

Background

An increasing number of patients are being prescribed anticoagulants and platelet inhibitors (antithrombotic treatment). Basic research has suggested an association between antithrombotic treatment and bacteremia during kidney infection. Here, we investigated the association between antithrombotic treatment, bacteremia and acute kidney injury in patients with acute pyelonephritis.

Methods

A retrospective cohort study was conducted in a large university hospital in Sweden. Data were retrieved from electronic medical records for adult patients with acute pyelonephritis in 2016. The main outcome was bacteremia and secondary outcome acute kidney injury. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated through multiple logistic regression. Treatment with different groups of antithrombotic agents were compared to no antithrombotic treatment.

Results

1814 patients with acute pyelonephritis were included, in whom bacteremia developed in 336 (18.5%). Low-molecular-weight heparin (LMWH) at prophylactic doses was associated with a lower risk of bacteremia, compared to no antithrombotic treatment (OR 0.5; 95% CI 0.3–0.7). Other antithrombotic treatments were not associated with a risk of bacteremia. Additionally, patients with prophylactic doses of LMWH had a lower risk of acute kidney injury (OR 0.5; 95% CI 0.3–0.8).

Conclusions

We found no association between antithrombotic treatment and an increased risk of bacteremia during acute pyelonephritis. Conversely, patients with prophylactic doses of LMWH had a slightly reduced risk of bacteremia. LMWH at prophylactic doses was also associated with a lower risk of acute kidney injury. Our results suggest that it is safe to continue antithrombotic treatment during acute pyelonephritis, in regards to bacteremia and acute kidney injury risk.

Management of Home Parenteral Nutrition: Complications and Survival

BACKGROUND AND AIMS

Parenteral nutrition (PN) has become an efficient, safe, and convenient treatment over years for patients suffering from intestinal failure. Home PN (HPN) enables the patients to have a high quality of life in their own environment. The therapy management however implies many restrictions and potentially severe lethal complications. Prevention and therapy of the latter are therefore of utmost importance. This study aims to assess and characterize the situation of patients with HPN focusing on prevalence of catheter-related complications and mortality.

METHODS

Swiss multicentre prospective observational study collecting demographic, anthropometric, and catheter-related data by means of questionnaires every sixth month from 2017 to 2019 (24 months), focusing on survival and complications. Data were analysed using descriptive statistics. Logistic regression models were fitted to investigate association between infection and potential co-factors.

RESULTS

Seventy adult patients (50% women) on HPN were included (≈5 patients/million adult inhabitants/year). The most common underlying diseases were cancer (23%), bariatric surgery (11%), and Crohn's disease (10%). The most prevalent indication was short bowel syndrome (30%). During the study period, 47% of the patients were weaned off PN; mortality rate reached 7% for a median treatment duration of 1.31 years. The rate of catheter-related infection was 0.66/1,000 catheter-days (0.28/catheter-year) while the rate of central venous thrombosis was 0.13/1,000 catheter-days (0.05/catheter-year).

CONCLUSION

This prospective study gives a comprehensive overview of the adult Swiss HPN patient population. The collected data are prerequisite for evaluation, comparison, and improvement of recommendations to ensure best treatment quality and safety.

[Catheter-related bloodstream infections in patients receiving central parenteral nutrition: prevalence, associated factors, and treatment]

Introduction

Background: catheter-related infection is one of the complications of central parenteral nutrition treatment with the highest morbidity and mortality. Objectives: the primary endpoint of this study was to analyze the prevalence of bloodstream infection in patients with central parenteral nutrition. Secondary objectives included: a) an assessment of whether type of central catheter, duration of parenteral nutrition treatment, body mass index, or being admitted to the intensive care unit are factors associated with the development of bloodstream infection; b) an analysis of the therapeutic approach. Methods: this was a retrospective observational study. All patients who received central parenteral nutrition after surgery between July 2018 and March 2019 were included. The association between the different variables and the development of bloodstream infection was analyzed by logistic regression. Results: the prevalence of bloodstream infection was 7.3 % (95 % CI: 3.9-13.3) (n = 9/123 patients). The duration of central parenteral nutrition was the only variable associated with the development of bloodstream infection (OR = 1.12; 95 % CI:1.05-1.20; p = 0.001). Conclusions: the prevalence of catheter-related bloodstream infection in this study is low, and the duration of central parenteral nutrition seems to be related to its development. However, further studies are needed to identify risk factors that might help reduce this kind of complications.

Reaching consensus on a home infusion central line-associated bloodstream infection surveillance definition via a modified Delphi approach

BACKGROUND

A consensus on a central line-associated bloodstream infection (CLABSI) surveillance definition in home infusion is needed to standardize measurement and benchmark CLABSI to provide data to drive improvement initiatives METHODS: Experts across fields including home infusion therapy, infectious diseases, and healthcare epidemiology convened to perform a 3-step modified Delphi approach to obtain input and achieve consensus on a candidate home infusion CLABSI definition.

RESULTS

The numerator criterion was identified by participants as involving one of the 2 following: (1) recognized pathogen isolated from blood culture and pathogen is not related to infection at another site, or (2) one of the following signs or symptoms: fever of 38°C (100.4°F), chills, or hypotension (systolic blood pressure ≤90 mm Hg), and one of the 2 following: (A) common skin contaminant isolated from 2 blood cultures drawn on separate occasions and organism is not related to infection at another site, or (B) common skin contaminant isolated from blood culture from patient with intravascular access device and provider institutes appropriate antimicrobial therapy. The criteria for a denominator included days from the day of admission with a central venous catheter to day of removal of central venous catheter. In addition, 11 inclusion criteria and 4 exclusion criteria were included.

DISCUSSION

Home infusion therapy and healthcare epidemiology experts developed candidate criteria for a home infusion CLABSI surveillance definition.

CONCLUSIONS

Home care and home infusion agencies can use this definition to monitor their own CLABSI rates and implement preventative strategies.

Antimicrobial Locks in Patients Receiving Home Parenteral Nutrition

Catheter-related bloodstream infection (CRBSI) is one of the most common and potentially fatal complications in patients receiving home parenteral nutrition (HPN). In order to prevent permanent venous access loss, catheter locking with an antimicrobial solution has received significant interest and is often a favored approach as part of the treatment of CRBSI, but mainly for its prevention. Several agents have been used for treating and preventing CRBSI, for instance antibiotics, antiseptics (ethanol, taurolidine) and, historically, anticoagulants such as heparin. Nonetheless, current guidelines do not provide clear guidance on the use of catheter locks. Therefore, this review aims to provide a better understanding of the current use of antimicrobial locking in patients on HPN as well as reviewing the available data on novel compounds. Despite the fact that our current knowledge on catheter locking is still hampered by several gaps, taurolidine and ethanol solutions seem promising for prevention and potentially, but not proven, treatment of CRBSI. Additional studies are warranted to further characterize the efficacy and safety of these agents.

Infectious Complications in Home Parenteral Nutrition: A Systematic Review and Meta-Analysis Comparing Peripherally-Inserted Central Catheters with Other Central Catheters

Background: Home parenteral nutrition (HPN) has become a common therapy. There is still controversy regarding the possibility that peripherally inserted central catheters (PICCs) may diminish catheter-related blood stream infection (CRBSI) rates. Methods: We searched the PubMed database for studies reporting the rates of CRBSI with HPN. Study selection was performed independently by three investigators. Disagreements were discussed and resolved by consensus or by arbitration by an author not involved in the search. The National Institutes of Health Quality Assessment Tools was used to assess the methodological quality of the studies. Meta-analyses were performed using MetaXL 5.3 with the quality effects model. Results: Screening of the article titles and abstracts yielded 134 full text articles for evaluation. Only three prospective studies that included appropriate data were considered for the final analysis. The relative risk of the CRBSI rate was 0.41 (0.14–1.17) for PICC vs. tunneled catheters. The relative risk of the CRBSI rate was 0.16 (0.04–0.64) for PICC vs. ports. The relative risk of the thrombosis rate was 3.16 (0.20–49.67) for PICCs vs. tunneled. Conclusions: There is insufficient evidence to show a difference in CRBSI rates between PICCs and tunneled catheters. On the other hand, PICCs showed lower CRBSI rates than ports. There was also no difference in the rate of catheter-related thrombosis and mechanical complications.

Epidemiology of Infectious and Noninfectious Catheter Complications in Patients Receiving Home Parenteral Nutrition: A Systematic Review and Meta-Analysis

Patients receiving parenteral nutrition (PN) as their primary source of nutrition are at high risk for both infectious and noninfectious catheter complications (catheter-related infections, catheter occlusion, and venous thrombosis). The aim of this review was to synthesize and evaluate what is known about catheter complications and prevention strategies in the PN population. Three electronic databases (Medline, Embase, and CINAHL) were screened for studies published between January 2012 and February 2019 regarding infectious and noninfectious catheter complications in patients receiving PN. Rates of infectious and noninfectious catheter complications, prevalence of causative pathogens, potential risk factors, and prevention strategies via the use of antimicrobial lock therapy (ALT) were assessed. Fifty-three catheter complication studies and 12 ALT studies were included. Studies were grouped by definition of complication: catheter-related bloodstream infections (CRBSI) or central line-associated bloodstream infections (CLABSI). Random effects summary rates per 1000 catheter days were 0.85 CRBSI episodes (95% CI 0.27-2.64) and 1.65 CLABSI episodes (95% CI 1.09-2.48). Use of taurolidine or ethanol ALT was efficacious in reducing infectious catheter complications; however, several studies had concerns for adverse mechanical complications. Potential risk factors for catheter complications were highly varied and often contradictory between studies. The rates of catheter complications were higher among catheterized patients receiving PN compared with nationally reported rates of complications in all catheterized patients. Risk factors for catheter complications need to be better understood for targeted prophylactic use of ALT. Future studies are warranted; however, they should be conducted using more standardized definitions and criteria.

Rate of Catheter-Related Bloodstream Infections Between Tunneled Central Venous Catheters Versus Peripherally Inserted Central Catheters in Adult Home Parenteral Nutrition: A Meta-analysis

BACKGROUND

Tunneled central venous catheters (TCVCs) and peripherally inserted central catheters (PICC) are often used for the provision of home parenteral nutrition (HPN). There is no formal comparison being made to study the rate of catheter-related bloodstream infection (CRBSI) between TCVCs and PICC in HPN to recommend the use of 1 over the other.

METHODS

An online MEDLINE, PubMed, and Scopus search was conducted. Studies reporting the rate of CRBSI in HPN patients were included. DerSimonian and Laird random effects meta-analyses were used to analyze comparative studies, whereas Begg and Pilote's random effects meta-analysis was used to pool and analyze single-arm studies.

RESULTS

Seventeen studies (12 single-arm studies and 5 comparative studies) were included for analysis. Meta-analysis of comparative studies showed that PICC use was associated with a significantly lower rate of CRBSI (relative risk (RR) 0.40, 95% CI 0.19-0.83), whereas meta-analysis of single-arm studies revealed that the relative risk for CRBSI was not statistically significantly different from unity.

CONCLUSION

TCVC is more commonly used in long-term HPN. Our analysis of comparative studies showed a lower rate of CRBSI in HPN patients using PICC compared with TCVC; however, analysis of single-arm studies showed that the rate of CRBSI was comparable in PICC and TCVC use. The decision to which type of catheter is most suited for HPN patients should hence be based on the duration of treatment, level of care, patients' dexterity, as well patients' underlying comorbidities that may potentially contribute to other catheter-related complications.

Epidemiology and Risk Factors for Outpatient-Acquired Catheter-Related Bloodstream Infections in Children Receiving Home Parenteral Nutrition

BACKGROUND

Few studies have examined the epidemiology and risk factors for the development of outpatient-acquired catheter-related bloodstream infections (CRBSIs) in children receiving home parenteral nutrition. This study aimed to (1) characterize the incidence, clinical presentation, and epidemiology of CRBSIs and (2) identify risk factors for CRBSIs in children receiving home parenteral nutrition.

METHODS

A longitudinal database approved by our Institutional Review Board was created to prospectively track CRBSIs in the UCLA pediatric population from January to December 2012. Eligible patients included those < 18 years old receiving home parenteral nutrition.

RESULTS

Thirty of 60 patients (50%) were diagnosed with 66 CRBSIs, for an overall CRBSI rate of 3.6 per 1000 catheter days. Of the CRBSIs, 73% were due to single microorganisms and 27% were polymicrobial. There was a significant difference in median (range) time for blood cultures to turn positive depending on type of CRBSIs (p = 0.03), with polymicrobial infections detected at 13.4 (8.7-24.3) hours, gram-negative infections at 16.5 (9-30.8) hours, and gram-positive infections at 18.9 (8.4-37.1) hours. The most common presenting symptom was fever (82%), followed by gastrointestinal symptoms (42%) and chills (29%). The only significant multivariate risk factor for CRBSIs was presence of a feeding tube (2.3-fold increase in CRBSI risk, p = 0.04).

DISCUSSION

Outpatient-acquired CRBSIs are common in children receiving home parenteral nutrition. CRBSIs typically present with fever, but are also associated with gastrointestinal and/or respiratory symptoms. The presence of feeding tubes may predispose children on home parenteral nutrition to developing CRBSIs.

Prospective evaluation of peripherally inserted central catheter complications in both inpatient and outpatient settings

We describe a prospective observational cohort (N = 187) to evaluate peripherally inserted central catheter line complications concurrently from the time of placement until removal. A significantly higher percentage of patients who experienced intraluminal thrombosis were receiving total parenteral nutrition (P ≤ .001) and had a dual lumen catheter (P = .01). Among patients with a confirmed or suspected infection, a significantly higher proportion received total parenteral nutrition (P = .01), had dual-lumen catheters (P = .04), and were neutropenic (P = .04).
