Purpose: Evaluate possibilities to reduce the number of infants screened for retinopathy of prematurity (ROP) and investigate costs and number of infants detected of current and alternative screening strategies in the Netherlands. Methods: Prospective population-based study including clinical data from all infants born in 2017 and referred for ROP screening (NEDROP-2 study). Cost and effects of screening strategies were evaluated that differed on the criteria gestational age (GA), birth weight (BW) and presence of one or more specific risk factor(s) (RF): mechanical ventilation, sepsis, necrotizing enterocolitis, postnatal corticoids and/or hypotension treated with inotropic agents. RF obtained from the Dutch perinatal registry (Perined). Results: Of the possible efficient strategies, the annual costs varied from euro137 966 (inclusion of BW < 700, 63 infants eligible for screening, detection of 17/39 treated ROP) to euro492 689 (GA < 30 weeks and BW < 1250 grams, together with infants with GA 30-32 and BW 1250-1500 grams with presence of one more RF, 744 infants eligible for screening, all treated infants detected). Total annual costs of the current Dutch guideline that detects all infants that need treatment for ROP amount to euro552 143). Conclusion: The current Dutch ROP guideline can be improved by implementing new screening inclusion criteria. The most effective strategy detecting all severe and treated infants, reduces the number of screened infants by 24% compared to the current guideline and the overall annual costs by euro59454.

METHODS: Retrospective inventory of anonymized neonatal and ophthalmological data of all patients treated for ROP from 2010 to 2017 in the Netherlands, subdivided in period (P)1: 1-1-2010 to 31-3-2013 and P2: 1-4-2013 to 31-12-2016. Treatment characteristics, adherence to early treatment for ROP (ETROP) criteria, outcome of treatment and changes in neonatal parameters and policy of care were compared. RESULTS: Overall 196 infants were included, 57 infants (113 eyes) in P1 and 139 (275 eyes) in P2, indicating a 2.1-fold increase in ROP treatment. No differences were found in mean gestational age (GA) (25.9 ± 1.7 versus 26.0 ± 1.7 weeks, p = 0.711), mean birth weight (791 ± 311 versus 764 ± 204 grams, p = 0.967) and other neonatal risk factors for ROP. In P2, the number of premature infants born

PurposeProvide up-to-date insight in incidence of retinopathy of prematurity (ROP), logistics of screening and treatment in the Netherlands and influence of the new national ROP guideline in which more stringent screening criteria were implemented and the early treatment for ROP criteria (ETROP) were emphasised.MethodsMulticentre prospective nationwide study including all preterm infants, born in the Netherlands in 2017, and considered eligible for ROP screening. Anonymised data from ophthalmologists and paediatricians were merged. Outcome data were compared with the first national ROP inventory (NEDROP-1, 2009).ResultsIn 2017, 1492 infants were live born with gestational age (GA) ConclusionThe overall ROP incidence expressed as a percentage, remained stable but the number of infants that developed severe ROP nearly doubled. A near one-third reduction in screened infants shows satisfactory implementation of the new screening criteria. A notable decrease in retinal detachment delineates improved treatment outcome.

Introduction: Retinopathy of prematurity (ROP) remains an important cause for preventable blindness. Aside from gestational age (GA) and birth weight, risk factor assessment can be important for determination of infants at risk of (severe) ROP. Methods: Prospective, multivariable risk-analysis study (NEDROP-2) was conducted, including all infants born in 2017 in the Netherlands considered eligible for ROP screening by pediatricians. Ophthalmologists provided data of screened infants, which were combined with risk factors from the national perinatal database (Perined). Clinical data and potential risk factors were compared to the first national ROP inventory (NEDROP-1, 2009). During the second period, more strict risk factor-based screening inclusion criteria were applied. Results: Of 1,287 eligible infants, 933 (72.5%) were screened for ROP and matched with the Perined data. Any ROP was found in 264 infants (28.3% of screened population, 2009: 21.9%) and severe ROP (sROP) (stage ≥3) in 41 infants (4.4%, 2009: 2.1%). The risk for any ROP is decreased with a higher GA (odds ratio [OR] 0.59 and 95% confidence interval [CI] 0.54–0.66) and increased for small for GA (SGA) (1.73, 1.11–2.62), mechanical ventilation >7 days (2.13, 1.35–3.37) and postnatal corticosteroids (2.57, 1.44–4.66). For sROP, significant factors were GA (OR 0.37 and CI 0.27–0.50), SGA (OR 5.65 and CI 2.17–14.92), postnatal corticosteroids (OR 3.81 and CI 1.72–8.40), and perforated necrotizing enterocolitis (OR 7.55 and CI 2.29–24.48). Conclusion: In the Netherlands, sROP was diagnosed more frequently since 2009. No new risk factors for ROP were determined in the present study, apart from those already included in the current screening guideline.
