4.1
System benefits associated with the moorLDI2-BI for burn wound assessment are based on reducing the length of hospital stay and avoiding unnecessary skin grafting operations.
Guidance
4 NHS considerations
System impact
4.2
Timing of moorLDI2-BI imaging is important because burn wounds change rapidly in the first 48 hours after injury. The evidence suggested that the best time for imaging is 48 to 72 hours after the injury, but the device can be used up to 5 days after injury.
4.3
Wound assessment using the moorLDI2-BI needs a trained clinician to operate the device and to interpret the results. In a study to assess clinical benefit, La Hei et al. (2006) reported an increase in accuracy of interpretation of the laser doppler images by a new assessor from 83% (15/18) to 96% (73/76) over a 6‑month period.
Committee considerations
4.4
The committee considered that earlier and more accurate prediction of the need (or lack of need) for surgery using the moorLDI2-BI would benefit the system by reducing unnecessary operations and by saving on inpatient care. These are considered further in the cost modelling (see section 5.2).
4.5
The committee was advised that training is important for all staff to operate this device and interpret the images. The cost model includes costs for 2 days' training for one consultant, two registrars and three nurses every 2 years for each device.
