“…Mattia et al 19,20 reported an association between cumulative illness severity and neurodevelopmental outcome in premature infants p30 weeks gestation at birth. Those in the highest quartile for cumulative SNAP score from their entire newborn hospitalization were more likely to have abnormal gross motor and psychomotor development at 2 to 3 years and 4 to 5 years of age than infants with a less severe hospital course.…”

“…18 Summation of serial illness severity scores, or cumulative illness severity, a measure of sustained exposure to physiological instability, was used in two studies of premature infants to account for differences in neurodevelopmental and cognitive outcomes. 19,20 No study has explored the relationship between cumulative illness severity and development of severe ROP. Moreover, fluctuation of illness severity scores over time has not been explored as a possible risk factor for ROP.…”

Objective: To test cumulative neonatal illness severity (IS) and IS fluctuation as predictors of progression from moderate to severe retinopathy of prematurity (ROP).Study Design: Data from research databases and medical record review were collected for infants from four neonatal intensive care unit (NICUs) admitted between 1995 and 2001 and diagnosed with prethreshold ROP. Cumulative neonatal IS measured using daily Scores for Neonatal Acute Physiology (SNAP) for the first 28 days of life, and IS fluctuation as assessed by summing changes between daily SNAP scores, were tested as predictors of progression to threshold ROP using logistic regression.Result: Infants progressing to threshold (n ¼ 79), compared to those not progressing to threshold (n ¼ 130), had significantly (P<0.05) lower gestational ages (25.2±1.1 versus 25.8±1.4 weeks), higher cumulative neonatal SNAP (255±77 versus 224±63 weeks) and had more severe hospitalizations as indicated by diagnoses and medical management. In regression analysis, gestational age, chronological age and presence of plus disease at first diagnosis of prethreshold were associated with development of threshold. After adjusting for these factors, cumulative neonatal SNAP was significantly associated with progression to threshold. However, addition of cumulative SNAP to the model only increased receiver-operating characteristic curve area from 0.77 to 0.78 (NS). Other factors, including SNAP fluctuation, were not associated with progression to threshold after adjustment using this model. Conclusion:Cumulative neonatal IS, as measured by cumulative SNAP, is an independent risk factor for progression from moderate to severe ROP. However, cumulative IS does not enhance assessment of risk for ROP progression after adjusting for simpler clinical factors.
