Background: Body surface area (BSA) is usually estimated by calculation with mathematical formulae. Three-dimensional body scanning (3D scan) offers a suitable alternative. Objectives: We determined the BSA in healthy term and near-term neonates by 3D scanning. This system should be useful in the setting of intensive care medicine. Methods: The measuring system consisted of a projector, two cameras, mirrors and a computer, and used the fringe projection technique with visible light. The infants were examined in a supine position; the hidden parts of the bodies were corrected for using a mathematical factor developed with a baby doll model. Results of the 3D scans were compared with those from five mathematical formulae for each subject. Results: A total of 209 infants were studied by 3D scanning, of whom 53 had acceptable images and were selected for further analysis. The mean BSA was 2,139 cm² (SD 223.72). The minimal BSA was 1,587 cm², the maximal 2,670 cm², with a good correlation to body weight and length. One mathematical formula (Du Bois and Du Bois) showed a distinct underestimation of BSA compared to 3D scanning, the others an overestimation. Mean percentage similarity was from 96.8 to 100.9%. Conclusions: 3D scanning is an accurate and practical method to estimate BSA in newborns. Individual and repeated measurements from day to day are possible. Further studies are warranted in preterm and sick neonates.

“…In clinical practice, BSA is usually calculated with well-known mathematical formulae, which were developed from direct or indirect measurements in adults [1][2][3][4][5][6] . However, neonates were seldom subjects of these studies and only a few formulae such as that of Meban or Mosteller are recommended for use in newborns [7] .…”

“…Reasons for why those methods are inappropriate for the analysis in method comparison study will be discussed in Sections 3 and 4. One example of the inappropriate application of statistical methods in method comparison study is in the study to explore the suitability of existing formulas to estimate the body surface area (BSA) of new-borns [18]. The authors compared different methods of estimation of body surface area in newborn and used correlation coefficient to determine the agreement of those methods [18].…”

“…The authors compared different methods of estimation of body surface area in newborn and used correlation coefficient to determine the agreement of those methods [18]. In one of their results, the authors described that the method of estimating body surface area (BSA) using the BSA-Meban was most similar to the BSA-Mean, by having a mathematically perfect correlation with r = 1.00 (p = 0.000) [18]. However, their conclusion was obviously inappropriate because the correlation coefficient only measures linear relationship, and does not suggest that the two methods give similar results.…”

In medicine, accurate measurement of clinical values is vital, either at the stage of health screening, diagnosing cases or making prognosis. There are numerous instruments or machines that have been invented for the purpose of measuring various clinical variables such as blood pressure, glucose level, body temperature and oxygen level. When a new method of measurement or instrument is invented, the quality of the instrument has to be assessed. This chapter will focus on the application of statistical methods used to analyse continuous data in a method comparison study or validation study in medicine. The concept of validity and analysis in method comparison study will be discussed. This chapter also reviews the theoretical aspects of several common methods and approaches that have been used to measure agreement and reliability including the Bland-Altman limits of agreement (LoA) and intra-class correlation coefficient (ICC). Issues related to method comparison studies will be highlighted, which include the evaluation of agreement and reliability in a single study, the application of multiple statistical methods and the use of inappropriate methods in testing agreement and reliability. Finally, the importance of education in method comparison studies among medical professional will be emphasized.
