Risk factors associated with Retinopathy of Prematurity development and progression.

ABSTRACT: Several studies propose that Retinopathy of Prematurity (ROP) is a multifactorial disorder implicating many prenatal and postnatal factors. The objective of our study was to determine the incidence and the risk factors that influenced ROP development and progression. We retrospectively compiled data of preterms with birth weight (BW) ≤ 1.500 g and/or gestational age (GA) < 32 weeks, or BW between 1.501 and 2.000 g and/or GA ≥ 32 weeks with oxygen supply > 72 h or unstable clinical course screened for ROP in Regional University Hospital of Málaga from 2015 to 2018. 202 infants (44.7%) developed ROP and 66 exhibited progression (32.7% of ROP infants). In the univariate analysis, many risk factors were associated with ROP. In the subsequent multivariate analysis, GA, oxygen therapy and weight at 28 days of life, mechanical ventilation duration, non-invasive ventilation, surfactant administration and late-onset sepsis were independently associated with the development. However, oxygen therapy duration, late-onset sepsis and weight at 28 days were associated with the progression. The ROP development and progression risk factors were different. Our results are important to facilitate screening, early diagnosis and ROP treatment while reducing unneeded examinations.

Project description:ImportanceMost premature infants will not develop retinopathy of prematurity (ROP) of clinical relevance, yet screening evaluations often continue beyond hospital discharge, even for those infants without ROP.ObjectivesTo identify the characteristics of infants at low risk for ROP, for whom further postdischarge screening may be of limited value.Design, setting, and participantsThis study took place in North American neonatal intensive care units where clinicians had expertise in ROP. Infants with birth weight less than 1251 g who were born at or transferred into an Telemedicine Approaches to Evaluating Acute-Phase ROP (e-ROP) study center were enrolled. The study included post hoc analysis of prospectively collected in-hospital ROP examination results among infants enrolled in the e-ROP study. We characterized infants without ROP and performed logistic regression on the subset of infants who were 27 to 33 weeks' gestational age to determine characteristics associated with the absence of ROP during all in-hospital examinations.Main outcomes and measuresThe main measure was the absence of ROP prior to hospital discharge; the main outcome was treatment for ROP.ResultsA total of 1257 infants born at 22 to 35 weeks' gestation (median [interquartile range (IQR)], 26 [25-28] weeks) with birth weights less than 1251 g (median [IQR], 860 [690-1040] g) underwent 4113 ROP examinations between 31 and 47 weeks' postmenstrual age. Overall, 1153 examinations (38%) showed no ROP, and 456 infants (36%) did not have ROP prior to study center discharge or study end point. Among infants without ROP during examinations at 32 and 33 weeks' postmenstrual age, 16 (9.4%) and 14 (5.3%) subsequently underwent ROP treatment, respectively. At hospital discharge, there was no ROP in 59% of infants of 27 to 33 weeks' gestational age, compared with 15% of those who were less than 27 weeks' gestational age (difference, 44% [95% CI, 38.5%-48.1%]; P ≤ .001). With more than 85% follow-up among infants without ROP by 37 weeks' postmenstrual age, none (95% CI, 0%-0.98%) were treated for ROP. In multivariate analysis of infants born at 27 to 33 weeks' gestation, larger birth weight (OR, 4.1 [95% CI, 1.6-10.3]) and higher gestational age (OR, 4.0 [95% CI, 1.5-10.8]) were significantly associated with absence of ROP.Conclusions and relevanceThese findings suggest that, for infants of 27 weeks' gestational age or greater and birth weights larger than 750 g, if no ROP has been detected by discharge at near-term postmenstrual age, then further ROP surveillance has limited value. Studies of all infants at risk are needed to develop more specific, objective criteria for termination of ROP surveillance and focus resources on infants at higher risk of ROP.Trial registrationClinicalTrials.gov Identifier: NCT01264276.
