Objectives: To evaluate and compare the risk of long-term central venous catheter (CVC) infection in human immunodeficiency virus (HIV)-infected and cancer patients.

Design: Prospective multicenter cohort study based on active surveillance of long-term CVC manipulations and patient outcome over a 6-month period.

Setting: Services of infectious diseases and oncology of 12 university hospitals in Paris, France.

Participants: In 1995, all HIV and cancer patients with solid malignancy were included at the time of long-term CVC implantation.

Results: Overall, 31.6% of long-term CVC infections were identified in 32% of 201 HIV and 5% of 255 cancer patients. Most were associated with bacteremia, most commonly coagulase-negative staphylococci. The long-term CVC time-related infection risk was greater in HIV than in cancer patients (3.78 vs 0.39 infections per 1,000 long-term CVC days; P<.001). The independent risk factors of long-term CVC infection were as follows: in HIV patients, frequency of long-term CVC handling and neutropenia; in cancer patients, poor Karnofsky performance status; in both HIV and cancer patients, recent history of bacterial infection. The risk of long-term CVC infection was similar for tunneled catheters and venous access ports in each population.

Conclusions: Prevention of long-term CVC infection should focus first on better sterile precautions while handling long-term CVC, especially in HIV patients who have frequent and daily use of the long-term CVC.

Background: Patients in critical care units (CCUs) are at an increased risk of bloodstream infections (BSIs), which can be associated with central vascular catheters (CVCs). This study describes BSIs, CVC-BSIs, organism distribution, percentage of antimicrobial resistant (AMR) organisms, and case fatality rates (CFRs) over the first six years of a voluntary national CCU surveillance programme in England.

Methods: Surveillance data on BSIs, CVCs, and bed-days between 04/2017 and 03/2023 for adult CCUs were linked to mortality and AMR data, and crude rates were calculated.

Background: Central venous catheters (CVCs) are used in pediatric patients to deliver IV fluids, blood products, medications, and nutrients. Potential complications include central line infection, which carries a high risk of morbidity and mortality in this population. Pediatric critical care nurses play a crucial role in helping to reduce the risk of infection.

Rationale & Objective: Peritoneal dialysis (PD) is a dialysis modality limited by the potential need of transferring to hemodialysis. Optimal hemodialysis vascular access is an arteriovenous fistula. Back-up arteriovenous fistula (bAVF) is a strategy to prevent central venous catheter (CVC) insertion, but its use in the PD population has not been systematically reviewed.
