Abstract
BackgroundCatheter-related bloodstream infections (CRBSIs) are associated with high morbidity and mortality as well as increased medical costs. Cancer patients, who are often immunocompromised, are susceptible to CRBSI while receiving home parenteral nutrition (HPN). We evaluated the incidence of and factors associated with CRBSIs in cancer patients undergoing HPN managed using a standardized catheter care protocol.MethodsThis is a retrospective cohort study of 335 cancer patients receiving HPN between January 2012 and July 2015. The primary outcome of interest was the incidence of CRBSI expressed as events per 1000 HPN days. HPN days were calculated from the start date with the home infusion provider until the discontinuation of HPN, or the removal of the venous access device (VAD), or the death of the patient. The VADs used were either peripherally inserted central catheters (PICCs) or a subcutaneous implanted port or tunneled central catheters (TCCs). Univariate Poisson regression analyses were used to determine the variables associated with CRBSIs.ResultsOf 335 patients, 193 were females and 142 were males. The most common cancer types were colorectal, pancreatic, ovarian and stomach. A total of 408 VADs in 335 patients were studied, covering a total of 29,403 HPN days. Of 408 VADs, 206 (50.5%) were ports, 191 (46.8%) were PICCs, and 7 (2.7%) were TCCs. The median duration of HPN was 54 days. A total of 16 CRBSI episodes were recorded (8 in ports, 7 in PICCs and 1 in TCCs). The median duration from the start of HPN to the development of CRBSI episodes was 43.5 days. The overall incidence of CRBSI per 1000 HPN days was 0.54 (95% confidence interval: 0.32–0.86). Upon univariate analysis, no variables were found to be statistically significantly associated with CRBSI incidence.ConclusionsWe found a low rate of CRBSI following a standardized catheter maintenance protocol in a high-risk oncology population undergoing HPN.
Highlights
Catheter-related bloodstream infections (CRBSIs) are associated with high morbidity and mortality as well as increased medical costs
The aims of the present study were to evaluate the following in a case series of patients with advanced solid tumors treated at a tertiary care cancer center in the US: 1) The incidence of CRBSI while receiving home parenteral nutrition (HPN) using a standardized catheter care protocol; 2) Factors associated with CRBSI development
There were no losses to follow-up and all patients were included in the final analysis
Summary
Catheter-related bloodstream infections (CRBSIs) are associated with high morbidity and mortality as well as increased medical costs. Cancer patients, who are often immunocompromised, are susceptible to CRBSI while receiving home parenteral nutrition (HPN). We evaluated the incidence of and factors associated with CRBSIs in cancer patients undergoing HPN managed using a standardized catheter care protocol. Cancer patients often require central venous access for continuous infusion of chemotherapeutic agents, hydration, and parenteral nutrition (PN) [1]. Central venous devices are either simple catheters, such as tunneled Hickman catheters, or catheters linked to a subcutaneous port. Both types of VADs, simple or port catheter, are placed percutaneously via a subclavian route or a jugular route under sonographic guidance [5].
