79 One Center’s Experience with the Use of Laser Treatments for Burn Scar
Bibliographic record
Abstract
The use of lasers to modify burn scars has advanced from a novel technique to a viable strategy. Further, the high cost of ownership of lasers can deter their use. We conducted a review of our experience with light-based treatment of burn scars, including some cases of early treatment (during the acute admission) using rented laser equipment. The routine access to PDL and FXCO2 lasers was initiated in December of 2015 at our burn center. An IRB-approved retrospective review of our clinical experience and program development was conducted. Data collected included demographic data, the Patient Observer Scar Assessment Scale (POSAS), Vancouver scar scale, complications, number of treatments, type of treatment, description of laser treatment, scar location and size, and a cost analysis. Forty- eight patients completed therapy, including four patients treated during the acute admission. Mean age of patients was 44.8 range 17–76. Initial outpatient clinic treatments were restricted to use of the PDL. FXCO2 treatment was combined with other surgical procedures under general anesthesia (n=3) until early 2017 when FXCO2 was offered in the outpatient clinic (n=12). Of the 106 outpatient treatments, there were two cases of blistering (with PDL) and one case of graft loss (PDL). Despite a trend in improvement of the total POSAS score from time 1 to 3 for both the total patient and total observer POSAS score it was not significant (p = 0.59 patient and p =0.09 observer). Patient itch score demonstrated improvement from time 1 to time 3 however it was not significant (p = 0.22). Financial analysis revealed profitability in the use of both FXCO2 and PDL lasers in the clinic. The initiation of a laser program can be accomplished with rental of a laser. Furthermore, it can be done safely both in the inpatient and outpatient setting and can be profitable for a burn center. Our experience indicates that in cases where purchase of a laser poses a prohibitive barrier to offering laser therapy, lase rental may offer a viable alternative.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
