Impact of the I‐ DECIDED Tool to Improve Peripheral Intravenous Catheter Care in Paediatrics: Interrupted Time‐Series Study

ABSTRACT Aim To determine whether the I‐DECIDED assessment and decision tool enhances peripheral intravenous catheter assessment, care and decision‐making in paediatrics. Design Quasi‐experimental, interrupted time‐series study. Methods An interrupted time‐series study was conducted in a paediatric inpatient unit at a public teaching hospital in Brazil. The participants were patients aged less than 15 years old with a peripheral intravenous catheter, and their parents or guardians. Data were collected between January and July 2023, encompassing six time points, three pre‐intervention and three post‐intervention. Evaluation data were based on the I‐DECIDED tool, including idle devices, dressings, complications, patient/family awareness, hand hygiene, disinfection and documentation. Results We conducted 585 peripheral intravenous catheter observations, with 289 in the pre‐intervention phase and 296 in the post‐intervention phase, inserted in 65 hospitalised children, 30 in the pre‐intervention phase and 35 in the post‐intervention phase. After the intervention, reductions were observed in the number of idle catheters, substandard dressings and complications. Patients and family members reported an increase in device assessment, hand hygiene and peripheral intravenous catheter disinfection. Additionally, there was an increase in documentation of decision‐making performed by nurses and nursing technicians/assistants. Conclusion Implementation of the I‐DECIDED assessment and decision tool in a paediatric unit significantly improved the assessment, care and decision‐making regarding peripheral intravenous catheters. Implications for the Profession and/or Patient Care Opportunity to enhance practice standards, elevate the quality of care provided to paediatric patients, contribute to improved patient outcomes, advance evidence‐based practice in vascular access management and enhance patient experience through increased involvement in care. Impact To influence clinical practice and healthcare policies aimed at improving peripheral intravenous catheter care and patient safety in paediatric settings.
