Cost-effectiveness of Laser Doppler Imaging in Burn Care in the Netherlands

Detailed Summary

Accurate early burn depth assessment is important to determine the optimal treatment. The most applied method to asses burn depth is clinical assessment. This method is the least expensive, but not very accurate. Laser Doppler imaging (LDI) has been shown to accurately assess burn depth. The clinical effects, the costs and cost-effectiveness of this device however, are unknown. The hypothesis is that an eary accurate diagnosis will lead to an earlier therapeutic decision: surgery or no surgery. Earlier excision and grafting probably leads to a decrease in wound healing time, in length of hospital stay and in costs. Before the investigators decide to implement LDI in Dutch burn care a study of the clinical effects and cost-effectiveness of LDI is necessary. Therefore a multicenter randomized controlled trial will be conducted, including all patients with burns of indeterminate depth (burns that are not obviously superficial or full thickness) treated in the Dutch burn centres. In total 200 patients will be included in an 18 months period. The patients are randomly divided in two groups: 'new diagnostic strategy' versus 'current diagnostic strategy'. Burn depth will be diagnosed both by clinical assessment and laser Doppler imaging in all patients. The results of the LDI-scan will be provided to the treating clinician in the 'new diagnostic strategy' group only. Time to wound healing, diagnostic and therapeutic decisions, and costs are observed.
