Central Line-Associated Bloodstream Infection in Patients With Hematologic Malignancy Receiving Parenteral Nutrition.

PURPOSE: Parenteral nutrition (PN) has been shown to be a safe method of feeding in the intensive care unit with modern infection prevention practices, but similar analysis in the hematology-oncology setting is lacking. METHODS: A retrospective analysis of 1,617 patients with hematologic malignancies admitted and discharged from the Hospital of the University of Pennsylvania during 3,629 encounters from 2017 to 2019 was undertaken to evaluate the association of PN administration with risk of central line-associated bloodstream infection (CLABSI). Proportions of mucosal barrier injury (MBI)-CLABSI and non-MBI-CLABSI were also compared between groups. RESULTS: Risk of CLABSI was associated with cancer type and duration of neutropenia but not with PN administration (odds ratio, 1.015; 95% CI, 0.986 to 1.045; P = .305) in a multivariable analysis. MBI-CLABSI comprised 73% of CLABSI in patients exposed to and 70% in patients not exposed to PN, and there was no significant difference between groups (χ2 = 0.06, P = .800). CONCLUSION: PN was not associated with increased risk of CLABSI in a sample of patients with hematologic malignancy with central venous catheters when adjusting for cancer type, duration of neutropenia, and catheter days. The high proportion of MBI-CLABSI highlights the effect of gut permeability within this population.

Effect of malnutrition-driven nutritional support protocol on clinical outcomes in autologous stem cell transplantation patients.

PURPOSE: Poor nutrition status in patients receiving high-dose chemotherapy and autologous stem cell transplant (ASCT) has been associated with inferior clinical outcomes. We aim to determine whether a malnutrition-driven nutritional support protocol can improve these outcomes. METHODS: In this prospective cohort study, we assessed adults for malnutrition who were consecutively admitted for ASCT between October 2017 and March 2019 (n = 251), and provided enteral or parenteral nutrition (EN/PN) to patients who were malnourished early in the transplantation admission. We compared their clinical outcomes with those of a historical cohort admitted between May 2016 and October 2017 (n = 257) for whom nutrition assessment and initiation of EN/PN were not protocol-driven. RESULTS: Patients receiving ASCT during the intervention period experienced decreased odds of prolonged hospital stay (p = 0.023), central line-associated bloodstream infection (p = 0.015), mucosal barrier injury (p = 0.037), and high weight loss (p = 0.002), in a multivariate analysis as compared with those receiving ASCT during the control period. Outcomes for ICU transfer, deconditioning on discharge, time to platelet engraftment, and unplanned 30-day hospital readmission did not differ significantly between groups. CONCLUSION: A malnutrition-driven nutritional support protocol may improve outcomes for ASCT patients.

Nutrition-Related Outcomes for Autologous Stem Cell Transplantation Patients.

INTRODUCTION: Autologous stem cell transplantation (ASCT) patients are at risk for malnutrition before transplantation admission as well as malnutrition acquired during their transplantation admission. PATIENTS AND METHODS: In this retrospective, observational study we examined data related to consecutive adults (n = 330) admitted for ASCT between 2014 and 2016 at the Hospital of the University of Pennsylvania. Malnutrition risk on admission (identified by the Malnutrition Screening Tool) and transplantation-associated weight loss were analyzed for independent associations with hospital length of stay, nosocomial infection, intensive care unit transfer, deconditioning, time to platelet and neutrophil engraftment, 30-day readmission, and 1-year mortality. RESULTS: Adults with high malnutrition risk (n = 60) had a longer median hospital stay (P = .004), longer median time to platelet engraftment (P = .022), increased nosocomial infections (P = .047), and increased 1-year mortality (P = .036). Adults with high transplantation-associated weight loss (n = 100) experienced longer hospital stays (P < .001) and more intensive care unit transfers (P = .001). Outcomes for deconditioning, time to neutrophil engraftment, and 30-day readmission did not differ significantly on the basis of nutrition risk or weight loss. CONCLUSION: Further research is needed to determine whether early nutrition intervention would improve these outcomes.
