The objective of this study was to analyze the financial implications of the implementation of new institutional practice guidelines including greater outpatient care and earlier operative intervention in a provincial burn center. A retrospective review was performed including all patients admitted to the Burn Unit with burns up to 20% TBSA between August 2005 and July 2009, including 2 years before and after the new guidelines were introduced. Daily costs for the burn unit were used to calculate this portion of cost. ⋯ With an average of 66 such patients treated each year, potential annual cost savings are Can$1.3 million. If outcomes are not compromised, earlier operative management and greater outpatient care can translate into significant cost savings. A prospective analysis capturing all costs and patient quality of life is required for further assessment.

Increasingly, patients are being evaluated for burns related to home oxygen use. Although the majority of burns are minor, referral to a burn unit regardless of depth or size is still common. The care of this population was reviewed to determine the feasibility and potential saving if such patients could be managed by nonburn-trained surgeons. ⋯ Average distance by helicopter transport was 57 miles, and cost $12,500.00. Large savings could be realized if patients cared for by local physicians were educated in basic burn care. This would be more palatable with good communication between the community hospital and burn center, with consultation on an as-needed basis.

Laser Doppler imaging (LDI) has been increasingly used to predict pediatric burn wound outcome. A majority of these wounds are scald, contact, or flame burns. No study has specifically evaluated the use of LDI in pediatric friction burns. ⋯ Of the remaining five incorrect predictions, four were caused by an inability to correlate the flux scan with the clinical appearance of the burn, and one was thought to take more than 21 days to heal but healed within this period. Our data suggest that LDI appears to be a less reliable tool in predicting the outcome of friction burns when compared to other mechanisms of burn injury in children. This may reflect the physical differences in the mechanism of friction burns as opposed to other forms of thermal injury.

We evaluated vancomycin levels as recent guidelines for therapeutic monitoring of vancomycin (not available at the time these data were collected) recommend trough levels of 15 to 20 μg/mL; however, this may be more difficult to achieve in patients with accelerated vancomycin clearance, such as burn patients or recipients of continuous venovenous hemofiltration (CVVH) therapy. We retrospectively studied 2110 serum vancomycin levels of 171 patients admitted to the burn intensive care unit for more than 4 years and who received vancomycin by continuous infusion (CI) or intermittent infusion (II), with or without simultaneous CVVH. In-hospital mortality, 14- and 28-day mortality following vancomycin therapy were not different between dosing methods, although increased mortality was observed in the subgroup of patients receiving CI vancomycin empirically for clinical sepsis with negative blood cultures. ⋯ CI produced more frequent therapeutic vancomycin levels and less frequent subtherapeutic levels compared to II. However, therapeutic vancomycin levels were achieved infrequently by either method of dosing. Given equivalent therapeutic drug monitoring costs and the lack of a clear clinical benefit, the role of CI dosing remains to be defined in spite of practical and theoretical advantages, particularly when administered in the setting of CVVH.

Studies have shown that monocytes are hyporesponsive and that dendritic cells (DCs) are depleted in burn patients. We have recently shown in a mouse model that burn injury alters the transcriptional regulation in bone marrow progenitors and inhibits myeloid-derived DC (mDC) production. In the present study, using human burn patient peripheral blood mononuclear cells, we have shown an overexpression of MafB with a corresponding reduction in peripheral blood mononuclear cell-derived mDCs. ⋯ Furthermore, GATA-1+ and HLA-DR+ mDCs were increased following MafB silencing. Although burn injury augments the number of peripheral blood monocytes, the frequency of mDC is reduced. This impairment is likely secondary to the down-regulation of mDC differentiation by high MafB-expressing monocytes following burn injury.
