Peripheral intravenous catheters (PIVCs) are required by most hospitalised patients. Difficult intravenous access (DIVA) makes insertion challenging, with poor patient outcomes, treatment delays and resource waste from multiple insertion attempts, often by multiple clinicians. This exploratory qualitative case study aimed to investigate how clinical and executive hospital staff view PIVC insertions for patients with DIVA from a cost and efficiency perspective. Fifteen semi-structured interviews were conducted with staff from three large, urban Australian hospitals. Data was thematically analysed, with four themes generated: (1) PIVCs are not considered from a cost or resource use perspective; (2) resources required for successful PIVC insertion are variable and unpredictable; (3) limited funding and support exist for advanced skill and ultrasound-guided insertion; and (4) processes for PIVC training and competency are inefficient. Investment in advanced PIVC inserters (with ultrasound-guided cannulation skills, and ability to train and assess novice inserters), with clear escalation pathways to these clinicians may reduce inefficiencies and waste associated with difficult PIVC insertions.
