Imaging of Adult Burn Injuries

Burn injuries are a common presentation to A&E in the UK (175,000 per year) of whom 13,000 require hospital admission. Treatment of a single burn can cost more than £63,000, and is ultimately dependent on the depth. Most burns are assessed by experienced clinicians within a few days of injury. Accurate evaluation of burn depth can be very difficult with the naked eye. Inaccuracy can lead to longer hospital stays, worse scarring and greater financial costs for the NHS. Where the burn depth (and the degree of damage to the underlying blood supply of the skin) is not clear by visual inspection, adjuncts may be used to aid clinical decision-making. Currently, the "gold standard" method of assessing skin blood flow in order to help burn specialists in their assessment of burn depth is Laser Doppler Imaging (LDI). However, LDI machines can be very large, slow to collect the images, and a single imaging unit costs roughly £50,000. Consequently their use is restricted to the assessment of small burns in compliant patients treated in specialist units. Thermal imaging (thermography) has evolved rapidly as a useful diagnostic tool in many medical disciplines. Previous studies have shown that there are significant changes in skin physiology (such as temperature and pigmentation) depending on the depth of the burn. Portable, high-resolution thermal cameras are now affordable, easy to use and can provide numerical results in under a second. Similarly, measurement of skin pigment levels can be achieved using portable devices such as the Spectrophotometric Intracutaneous analysis scope (SIAscope). The aim of this study is to determine if alternative measures such as thermography or SIAscope can be as useful in the assessment of adult burns as LDI currently is. If this study demonstrates this then these results will inform further studies that would investigate these alternative imaging methods as a diagnostic and prognostic tool in the management of burns not only in adults but also in children presenting to non-specialised units such as A&E.
