Validation of the Effectiveness of the CFIR - ERIC Matching Tool in Implementation Research

Currently，the evidence-based practice research often isolates barrier assessment from implementation strategy development. At tne same time, many implementation science models being overly complex for clinicians. In Chinese, certain studies still neglect barrier assessment, demonstrate inconsistent conceptualization of implementation strategies, and rarely classify developed strategies. As a tool for matching and selecting implementation strategies, the CFIR - ERIC matching tool has the characteristics of strong pertinence, repeatability, structuring, systematization, and simple and convenient operation compared with other models. Researchers can identify barrier factors through CFIR and use the CFIR - ERIC matching tool to match strategies to promote the implementation of clinical intervention measures. This implementation study adopted a pre-post design using the CFIR-ERIC Matching Tool to analyze barriers and develop strategies. Grounded in the "Pediatric Venous Access Device Selection Decision Tree" from the 2021 clinical practice guideline on infusion therapy in children, the intervention was rolled out across 21 wards at the Children's Hospital of Fudan University. The implementation process of the evidence was evaluated from four aspects using the RE-AIM framework , including the evaluation indicators corresponding to each dimension of patient reach, intervention efficacy, medical adoption, and guideline implementation.
