Lower extremity burns and Unna paste: can we decrease health care costs without compromising patient care?

OBJECTIVE: To compare an alternative treatment for lower extremity burns with the standard in-hospital treatment, in an attempt to shorten hospital stay.

DESIGN: A case-control series.

SETTING: A university-affiliated hospital.

PATIENTS: All patients with a burn isolated to a lower extremity were treated over an 8-month period with split-thickness skin grafting (STSG), Unna paste dressing, immediate mobilization and early discharge. This group was compared with matched controls from the preceding 8 years treated with STSG, occlusive burn gauze dressing, bed rest and hospitalization.

MAIN OUTCOME MEASURES: Duration of hospital stay and graft viability.

RESULTS: Thirteen patients with an average wound size of 131 cm2 were treated with Unna paste and had a graft viability of greater than 95% and a burn-scar rating equivalent to that of patients treated with the earlier regimen. The duration of hospital stay decreased from a mean of 12.9 days to 1.4 days, with no complications. This translated into a saving of $10,350 per patient.

CONCLUSIONS: This alternative treatment is safe, inexpensive and effective and is recommended as the treatment of choice for uncomplicated, noncircumferential lower extremity burns.
