This study protocol describes a type 1 hybrid effectiveness-implementation study evaluating a clinical decision support dashboard for neonatal pain management in a tertiary NICU. Using a pre- and post-implementation design, the study assesses whether the dashboard reduces the duration of inadequately managed neonatal discomfort during the first seven days of admission, while concurrently evaluating implementation outcomes such as acceptability, appropriateness, fidelity, and penetration. Quantitative EHR- and dashboard-derived data are complemented by qualitative interviews and observations to provide a comprehensive evaluation of both clinical impact and implementation processes.
