Improving difficult peripheral intravenous access requires thought, training and technology (DART): a stepped-wedge, cluster randomised controlled trial protocol.

Background: Peripheral intravenous catheters (PIVCs) are the most used invasive medical device in healthcare. Yet around half of insertion attempts are unsuccessful leading to delayed medical treatments and patient discomfort of harm. Ultrasound-guided PIVC (USGPIVC) insertion is an evidence-based intervention shown to improve insertion success especially in patients with Difficult IntraVenous Access (BMC Health Serv Res 22:220, 2022), however the implementation in some healthcare settings remains suboptimal.

The Impact of Phenotypic Heterogeneity on Chemotactic Self-Organisation.

The capacity to aggregate through chemosensitive movement forms a paradigm of self-organisation, with examples spanning cellular and animal systems. A basic mechanism assumes a phenotypically homogeneous population that secretes its own attractant, with the well known system introduced more than five decades ago by Keller and Segel proving resolutely popular in modelling studies. The typical assumption of population phenotypic homogeneity, however, often lies at odds with the heterogeneity of natural systems, where populations may comprise distinct phenotypes that vary according to their chemotactic ability, attractant secretion, etc.

Quality measurement and surveillance platforms in critically ill children: A scoping review.

Background/aim: The objective of this study was to describe current surveillance platforms which support routine quality measurement in paediatric critical care.

Method: Scoping review. The search strategy consisted of a traditional database and grey literature search as well as expert consultation.

Patient blood management in critically ill children undergoing cardiac surgery: A cohort study.

Objective: The objective of this study was to audit current patient blood management practice in children throughout cardiac surgery and paediatric intensive care unit (PICU) admission.

Design: This was a prospective observational cohort study.

Setting: This was a single-centre study in the cardiac operating room (OR) and PICU in a major tertiary children's hospital in Australia.

Improving peripheral venous cannula insertion in children: a mixed methods study to develop the DIVA key.

Objective: To develop and validate a difficult intravenous access risk assessment and escalation pathway, to increase first time intravenous insertion success in paediatrics.

Methods: Mixed methods underpinned by literature and co-production principles. Iterative development of the instrument was informed through semi-structured interviews and stakeholder workshops.
