Human body surface area (BSA) is an established parameter for the calculation of chemotherapy drugs dosage, treatment of chronic hepatitis B, treatment of burns or for establishing a dosing regimen for antimicrobials. Although being a critical parameter, usage of modern 3D scanners, which would measure the exact BSA value, is often impossible in time-sensitive operations or for patients unable to withstand the scanning process. Therefore, over the last decades considerable research efforts have been devoted to development of simple formulae for BSA approximation. The formulae use a small number of state variables (weight, height, age, sex), which are intended to be easily obtained for every patient. The formulae parameters were estimated independently for isolated groups of subjects, which should rise suspicion whether any of the formulae used is indeed effective and safe for medical treatment. Here, we provide an extended analysis of 43 BSA formulae based on 152 patients scanned with a hand-held 3D scanner. Upon comparison of the real BSA values with estimations made by the formulae, we can conclude that most of the formulae exhibit a high relative BSA error, ranging from 9.83% to 43.27%.
