Validation of the FIRST-ROP algorithm in a tertiary care center in Greece
摘要
We aim to validate the previously published FIRST-ROP algorithm in a tertiary-level center.
MethodsThis is a retrospective consecutive study that includes premature infants screened for retinopathy of prematurity (ROP) at a tertiary referral center in Thessaloniki, Greece. Infants who did not meet criteria for microprematurity or nanoprematurity (i.e., infants born at ≥ 27 weeks gestational age and weighing ≥ 800 g) were included in the study.
ResultsOf the 1251 infants screened, 1094 (87.4%) met the inclusion criteria. ROP was detected in 103 patients (9.4%). Fourteen infants (1.3%) required treatment for active disease. The median postmenstrual age (PMA) at first ROP diagnosis was 34.7 weeks. No patients were diagnosed with type 1 ROP on either of the first two inpatient exams. The median PMA at first treatment was 38.1 weeks. The upper 95% confidence limit for missing a type 1 case when omitting the first and second ROP examinations was calculated to be 0.27% (95% CI, 0-0.27%). No patients were treated on the first or second exam.
ConclusionIn this medium-risk cohort of neonates not meeting criteria for microprematurity or nanoprematurity, in Greece, there were no patients treated on the first or second inpatient examinations. The FIRST ROP algorithm was validated to start screening at 34 weeks PMA. This is the first ex-US validation and may support the principle of risk-stratified ROP screening.
