Abstract:
Objective To study the transport risk and factors that influence deaths of very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.Method All infants transferred to our neonatal intensive care unit (NICU) by our hospital transport team or local hospital transport team from January 2014 to December 2015 were included in our study.Their clinical data were retrospectively studied.The risks of transport between hospitals were analyzed.The risk factors of deaths within and after 7 days of admission were further analyzed by multivariate Logistic regression analysis.The receiver operation characteristic (ROC) curve was used to assess the sensitivity and specificity of mortality index for neonatal transportation (MINT),transport related mortality score (TREMS),transport risk index of physiologic stability (TRIPS) for predicting mortality of preterm infants.Result (1) A total of 527 cases of ELBW/VLBW infants were included in our study.There were no deaths during transport.There were 10.2％ (54/527) died within and 8.9％ (42/473) died after 7 days of hospitalization.(2) Multivariate Logistic regression analysis showed that scleredema of newborn,secondary transport,gastrointestinal malformations,metabolic acidosis,high TREMS score,and high MINT score were risk factors of mortality within 7 days of admission for ELBW/VLBW infants;necrotizing enterocolitis,intraventricular hemorrhage ≥ three degree,high MINT score and low admission weight were risk factors of mortality after 7 days of admission.(3) The area under the ROC curve for MINT,TREMS,and TRIPS score were 0.672,0.655 and 0.665,respectively.The cut-off values for MINT score (cut-off 8,sensitivity 0.444,specificity 0.829),for TREMS score (cut-off 2,sensitivity 0.500,specificity 0.757,for TRIPS score (cut-off 20,sensitivity 0.444,specificity O.829) were selected to predict mortality within 7 days of admission.Conclusion (1) Secondary transport is the transport-related risk factor of mortality within 7 days of admission for ELBW/VLBW infants.(2) High MINT score is the risk factor of mortality within and after 7 days of admission.(3) If MINT ≥ 8,TREMS ≥2,or TRIPS ≥20,it might significantly increase the risk of mortality of ELBW/ VLBW infants within 7 days of admission after transport.
