Purpose: Validation of the new Postnatal Growth and Retinopathy of Prematurity (G‐ROP) criteria for screening of retinopathy of prematurity (ROP) in a Spanish tertiary care hospital with an advanced neonatal intensive care unit.
Methods: Retrospective cohort study that includes premature infants with current ROP screening criteria (less than or equal to 32 weeks of gestational age and/or less than or equal to 1500 g of birth weight) born between January 2017 and December 2021 in a tertiary care hospital with an advanced neonatal intensive care unit. The compliance with the G‐ROP criteria was assessed for each patient, including: gestational age <28 weeks, birth weight <1051 g, weight gain <120 g during 10–19 days postnatal age, <180 g during 20–29 days, <170 g during 30–39 days or hydrocephalus. The objective was to determine specificity, sensitivity and reduction of patients examined with these new criteria.
Results: Of 483 patients included (203 female and 280 male), the new G‐ROP criteria predicted 100% of cases of type 1 ROP (treatment‐requiring ROP) (15 of 15 cases) (Sensitivity 100%, Specificity 37.68%). Applying these criteria, there would be a reduction of 34.36% (166 patients) in infants requiring examination.
Conclusions: This study observes that the new G‐ROP screening criteria may suppose an increase of sensitivity and specificity with a reduction of the number of infants requiring screening. However, other studies with a larger population would be necessary to verify the results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
