Worldwide, there has been a shift in health care delivery, with an increasing emphasis on avoiding hospital admissions and providing treatment such as intravenous antibiotics for patients at home, using peripherally inserted central catheters (PICCs). However, there is inadequate data to demonstrate if rates of PICC failure are similar for hospital inpatients, currently understood to be between 7% and 36%, than those cared for at home. The objective of this study was to identify prevalence, dwell time, and complications associated with PICCs in the home setting. This single-center, retrospective cohort study of adults treated by the "Hospital in the Home" (HITH) program in Queensland, was conducted between June 1, 2017 and June 15, 2018. Clinical data were collected for patient and PICC characteristics. Variables were described as frequencies and proportions, means and standard deviations, or medians and interquartile ranges. In total, 304 patients treated by HITH during this timeframe, and 164 (54%) patients with 181 PICCs were included in this study. These patients were predominately male (n = 105, 64%), with a mean age of 54 years. The most common reason for admission was a wound infection and/or bone infection (n = 120, 33%). Most PICCs were single lumen (n = 120; 67%), inserted in the basilic vein (n = 137; 80%) by nurses (n = 122; 67%). Peripherally inserted central catheter failure occurred in 10% (n = 19); the most common complications were dislodgement (n = 9; 5%) and thrombosis (n = 4; 2%). There were no confirmed catheter-related blood stream infections. Peripherally inserted central catheter failure rates are similar between hospitalized inpatients and those cared for at home.

Background: Skin microorganisms may contribute to the development of vascular access device (VAD) infections. Baseline skin microorganism type and quantity vary between body sites, yet there is little evidence to inform choice of VAD site selection. Objective: To compare microorganisms present at different body sites used for VAD insertions and understand the effect of transparent dressings on skin microflora. Methods: The ESCAPE observational study consisted of three phases: (1) skin swabs of four sites (mid-neck, base neck, chest, upper arm) from 48 hospital patients; (2) skin swabs of five body sites (mid-neck, base neck, chest, upper arm, lower arm) from 10 healthy volunteers; and (3) paired skin swabs (n = 72) under and outside of transparent dressings from 36 hospital patients (16 mid/base neck, 10 chest, upper arm). Specimens were cultured for 72 h, species identified and colony-forming units (CFU) counted. Ordinal logistic regression compared CFU categories between variables of interest. Results: The chest and upper arm were significantly associated with fewer microorganisms compared to neck or forearm (odds ratio [OR] = 0.40, 95% confidence interval [CI] = 0.25–0.65, P < 0.05). CFU levels under transparent dressings were not significantly different from outside (OR = 0.57, 95% CI = 0.22–1.45). Staphylococci were predominant at all sites. Other significant (P < 0.05) predictors of higher CFU count included prolonged hospitalisation and medical/surgical patient status. Discussion: Skin microorganism load was significantly lower at the upper arm or chest, compared to the mid- or base neck. This may impact VAD site selection and subsequent infection risk.

Background: Peripheral vascular catheters (PVC) are the most frequently used invasive medical devices in hospitals, with 330 million sold each year in the USA alone. One in three UK inpatients at any one time has at least one PVC in situ according to the Scottish National Prevalence survey. Method: A narrative review of studies describing the infection risks associated with PVCs. Results: It is estimated that 30–80% of hospitalised patients receive at least one PVC during their hospital stay. Despite their prevalence, PVCs are not benign devices, and the high number of PVCs inserted annually has resulted in serious catheter-related bloodstream infections and significant morbidity, prolonged hospital stay and increased healthcare system costs. To date, PVC infections have been under-evaluated. Most studies focus on central venous catheter rather than PVC-associated bloodstream infections. Risks associated with PVC infection must be addressed to reduce patient morbidity and associated costs of prolonged hospital admission and treatment. Discussion: This article discusses the sources and routes of PVC-associated infection and outlines known effective prevention and intervention strategies. [ABSTRACT FROM AUTHOR]
