The Effect of Standard Concentration Infusions on Medication Errors in Neonatal and Pediatric Healthcare Settings: A Systematic Review.

Background and Objectives: Neonates and children are at high risk of medication errors (ME) with intravenous (IV) infusion therapies, particularly when strategies such as the "rule of six" with individualized, weight-based concentrations are used. Standard concentrations (SCs) have been proposed to reduce variability, improve safety, and facilitate the use of electronic prescribing and smart infusion technologies. The impact of SCs for continuous IV infusions on ME rates in neonatal and pediatric settings was systematically evaluated. Methods: A systematic review was conducted in MEDLINE, Embase and CINAHL (database inception-August 2025) following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies implementing SCs for neonatal or pediatric IV infusions and measuring outcomes referring to ME rates were included. The relative risk reduction/increase in MEs was calculated. Results: Five uncontrolled before-after studies published between 2005 and 2020 were included. The relative risk reductions ranged from 41.2% to 95.1% for overall ME and from 49.7% to 100% for selected error types. In two studies, the relative risk for two error types (paper-generated prescriptions, administration) increased after implementing SCs. Reviewed benefits included decreased calculation and preparation errors, reduced medication process times, improved workflow efficiency and high staff satisfaction. Conclusions: SCs may contribute to safer IV infusion practice in the neonatal and pediatric setting, especially combined with smart technologies and training. However, current evidence is limited and heterogeneous. Larger, prospective experimental studies are needed to confirm their long-term impact on pediatric ME rates.
