Abstract:
Objective To evaluate the role of a color jaundice card (6 colors) as a possible screening tool for detecting neonatal hyperbilirubinemia.Methods During February 1,2016 and May 31,2017,neonates were enrolled in the study,with gestational age ≥35 weeks,birth weight ≥2 000 g,postnatal age 3-28 days,who were the outpatients or inpatients of the 9th People's Hospital of Wuxi Affiliated to Soochow University and the People's Hospital of Anyang.In a well-lighted room,the card measurements were performed at the infants' forehead,the cheek and the sternum.The skin was pressed with a finger for 2 seconds and left quickly,and then the card was used to compare with the exposed yellow skin.Within 2 hours after jaundice card measurement,blood was obtained by venipuncture and total serum bilirubin (TSB) levels were measured.The sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV),positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were calculated at each measurement sites.Results One hundred and thirty-two neonates were enrolled,of whom 68 cases (51.5％) were male and 64 cases(48.5％) were female and 18 cases (13.6％) were preterm and 114 cases (86.4％) were term neonates.Among all neonates,TSB was ＜5.00 mg/dL(1 mg/dL =17.1 μmol/L) in 21 cases (15.9％),5.00-9.99 mg/dL in 26 cases (19.7％),10.00-14.99 mg/dL in 34 cases (25.8％),15.00-19.99 mg/dL in 37 cases (28.0％) and ≥ 20.00 mg/dL in 14 cases (10.6％).The card had the highest cap ability to recognize jaundice at the cheek,slightly lower at the sternum and the worst in the forehead.The cut-off of ≥ 12 on the six-color card at the cheek had a sensitivity of 95.95％,specificity of 74.14％,PPV of 82.56％,NPV of 93.48％,PLR of 3.710 and NLR of 0.055 for identifying neonates with TSB ≥ 12 mg/dL,with sensitivity being 98.08％,specificity 57.50％,PPV 60.00％,NPV 97.87％,PLR 2.308 and NLR 0.033 for TSB≥ 15 mg/dL.The identification rate was as follows:sensitivity of 100.00％,specificity of 46.00％,PPV of 37.21％,NPV of 100.00％ and PLR of 1.852 for predicting TSB ≥ 17 mg/dL.In addition,in the forehead,cheeks and sternum,the sensitivity of the cut-off of ≥ 12 on the card was 100.00％ for identifying neonates with TSB≥20 mg/dL.In the cheeks and the sternum,the cut-off of ≥ 15 on the card was with a sensitivity of 100.00％ for predicting TSB ≥ 20 mg/dL.Conclusion The six-color jaundice card is a potential screening tool for neonatal hyperbilirubinemia,and the cheek is the best measurement site.
