Barriers and facilitators to the national scale-up of a preterm standardised parenteral nutrition system: A mixed-methods evaluation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Standardising parenteral nutrition (PN) care for preterm infants is recommended to enhance safety, outcomes and efficiency, however implementation at scale remains challenging. In 2021, Ireland scaled-up a standardised parenteral nutrition (SPN) system comprising SPN formulations and dosing protocol. We evaluate national scale-up to identify contextually relevant factors to optimise implementation. Methods: A sequential explanatory mixed-methods process evaluation was conducted. Phase 1 comprised a cross-sectional survey of healthcare professionals (HCPs) across nine neonatal units (NUs), alongside analysis of PN purchasing data. Phase 2 included a focus group with the national implementation team and semi-structured interviews with HCPs from three NUs. Qualitative data were analysed using framework analysis guided by the Consolidated Framework for Implementation Research. Results: For Phase 1, we analysed 158 survey responses (27.6% response rate). All NUs had adopted the SPN system; 95% HCPs reported 'Always' or 'Often' using the protocol. SPN accounted for 95% of PN purchased nationally, increasing from 56% pre-implementation. Usability and sustainment scores were significantly higher among trained HCPs ( Conclusion: Scale-up of SPN interventions is achievable in practice, however contextual factors influenced how the intervention was used. System-level infrastructure including training and ongoing monitoring is required to optimise implementation and equitable sustainment.
