Bibliometric analysis with reference publication year spectroscopy showed how key programmes drove developmental care in newborn infants

Abstract

AbstractAimWe investigated the historical origins of developmental care for newborn infants using Reference Publication Year Spectroscopy (RPYS), an innovative method of bibliometric analysis.MethodsA Web of Science search query that combined infant and intervention‐related synonyms was performed on 2 February 2022. RPYS analysis was performed on this dataset to identify the most referenced historical publications for developmental care in newborn infants. Median deviation analysis identified the peak publication years, including the most cited historical references. Landmark publications were defined as those belonging to the top 10% of the most frequently referenced publications for at least 20 years.ResultsThe RPYS peaks showed an early phase (1936–1986), during which infant development was studied and analysed, leading to a conceptualisation of developmental care for newborn infants. The following years (1987–2020), showed an explosion of interest in developmental care and highlighted two main programmes. The Neonatal Individualized Developmental Care Assessment Program (NIDCAP) and the Infant Health and Development Program (IHDP) inspired numerous publications during those years, which strove to demonstrate evidence of their clinical benefits.ConclusionDevelopmental care has become increasingly important, thanks to the implementation of NIDCAP and IHDP.
