The use of score for neonatal acute physiology perinatal extention II (SNAPPE II) in predicting neonatal outcome in neonatal intensive care unit

Abstract

Background Scoring systems which quantify initial risks have animportant role in aiding execution of optimum health services by pre-dicting morbidity and mortality. One of these is the score for neonatalacute physiology perinatal extention (SNAPPE), developed byRichardson in 1993 and simplified in 2001. It is derived of 6 variablesfrom the physical and laboratory observation within the first 12 hoursof admission, and 3 variables of perinatal risks of mortality.Objectives To assess the validity of SNAPPE II in predicting mor-tality at neonatal intensive care unit (NICU), Soetomo Hospital,Surabaya. The study was also undertaken to evolve the best cut-offscore for predicting mortality.Methods Eighty newborns were admitted during a four-month periodand were evaluated with the investigations as required for the specifi-cations of SNAPPE II. Neonates admitted >48 hours of age or afterhaving been discharged, who were moved to lower newborn care <24hours and those who were discharged on request were excluded. Re-ceiver operating characteristic curve (ROC) were constructed to derivethe best cut-off score with Kappa and McNemar Test.Results Twenty eight (35%) neonates died during the study, 22(82%) of them died within the first six days. The mean SNAPPE IIscore was 26.3+19.84 (range 0-81). SNAPPE II score of thenonsurvivors was significantly higher than the survivors(42.75+18.59 vs 17.4+14.05; P=0.0001). SNAPPE II had a goodperformance in predicting overall mortality and the first-6-daysmortality, with area under the ROC 0.863 and 0.889. The best cut-off score for predicting mortality was 30 with sensitivity 81.8%,specificity 76.9%, positive predictive value 60.0% and negativepredictive value 90.0%.Conclusions SNAPPE II is a measurement of illness severity whichcorrelates well with neonatal mortality at NICU, Soetomo Hospital.The score of more than 30 is associated with higher mortality

Comparison of CRIB-II with SNAPPE-II as predictor of mortality and neurodevelopmental outcome at 12 months of age for newborns ≤ 32 weeks of gestational age

“…The variability in cutoff scores and discriminative performance could be attributed to factors in uencing the scores, including diseases, illness severity, and the quality of care within the NICU. The lower cutoff scores observed in this study for these scoring systems indicate a milder level of severity in this population compared to what was reported in previous studies (19,20). Both scores exhibited moderate sensitivity in predicting mortality, with SNAPPE-II had higher speci city.…”

“…No entanto, foi demonstrado que o maior número de RN com SNAPPE-II >24 foram classificadas nos estágios II e III da doença. Este resultado somado às menores médias do peso ao nascimento e IG alerta sobre o mau prognóstico do RN, inclusive aqueles com maior risco cirúrgico entre os acometidos pela ECN (Mia et al, 2005). Isto também foi evidenciado em relação às chances de óbito, onde se mostrou maior relação dos estágios II e III com a mortalidade, assim como apresentado por outros autores (Qian et al, 2017).…”

“…In the Supplementary File (provided as a link) in an article by Jayasheel et al, the calculations of number of participants "enrolled" and "missing" is not proper [1]. In discussion section, comparison of mean total scores is done with mean scores of a different one, which is not ideal [3].…”
