title: Digitisation of the total burn surface area.
abstract: The assessment of surface area of the body affected by a burn (TBSA) has long been estimated with manual charts. Initial assessment of burned patients is made frequently by clinicians with limited experience producing significant errors. Paper copies of burn charts are unwieldy, subject to loss and tend towards overestimation. Thus, a simple method of calculation, recording and transmission via email or telemedicine may produce benefits in both initial treatment and data recording. Although computer-based systems have been reported previously none have entered routine clinical practice in the UK. We devised a PC-based program, "Burn Calculator", whereby digital transcription of the burn allows automatic area calculation allowing not only a rapid, accurate figure for determination of fluid resuscitation, but also the potential for rapid electronic transmission. It also calculates fluid requirements to minimise errors during resuscitation. This initial pilot study compared figures from 50 paper charts with those from Burn Calculator to determine its accuracy and reproducibility. Previously reported variations in TBSA estimation were confirmed, as was the tendency towards TBSA underestimation resulting from transcription of a three-dimensional clinical situation to a two-dimensional representation. Burn Calculator showed high correlation (r=0.9850; p<0.0001) and reproducibility (R=0.9957) that would simplify assessment and referral plus facilitate data collection, interpretation and research.
