Logistics of building a laser practice for the treatment of hypertrophic burn scars

Impact of a Laser Service Line for Burn Scar on a Dedicated Burn OR's Flow and Productivity

Our group began performing erbium-YAG 2940 wavelength fractional resurfacing of burn scar in our burn center's dedicated burn operating room (OR) in January 2016. The impact of these procedures on the performance of a mature, dedicated burn OR is unknown. All burn OR cases performed between January 1, 2015 and December 31, 2015 served as a pre-laser (PRE-LSR) historical control. A postintervention cohort of laser-only cases (LSR) performed between January 1, 2016 and August 17, 2016 was then identified. PRE-LSR and LSR cases were retrospectively reviewed for OR component times, and work relative value units (wRVU) billed. A total of 628 burn OR cases were done in 2015 (PRE-LSR), while 488 burn OR cases were done between January 1 and August 17, 2016. Of these 488, 59 cases were LSR (12.1%). Calculated on a monthly basis, significantly more cases were done per day in the LSR era (2.2 ± 0.4 cases/d) than PRE-LSR (1.6 ± 2.0 cases/d; P < .0001). The LSR group was significantly shorter than the PRE-LSR group for all OR component times (induction, prep, and procedure all P < .0001; transport out, P = .01; room turnover, P = .004). Aggregate OR component time was 79.2 ± 33.4 minutes for LSR and 157.5 ± 65.0 minutes for PRE-LSR (P < .0001). LSR yielded 6.9 ± 3.2 wRVU/h, while PRE-LSR generated 12.2 ± 8.9 wRVU/h (P < .0001). Despite significantly shorter OR component times and more cases being done per day, laser treatment of burn scar using a single 17108 Current Procedural Terminology code cuts wRVUs generated per hour in a mature burn OR roughly in half.

Laser management of hypertrophic burn scars: a comprehensive review

Hypertrophic scars often develop following burn-related injuries. These scars can be cosmetically unappealing, but associated symptoms of pruritus, pain and restricted range of motion can impair a person’s quality of life. Laser and light therapies offer a minimally invasive, low-risk approach to treatment, with a short postoperative recovery period. As laser technology developed, studies have shown decreased scar thickness, neuropathic pain and need for surgical excision, as well as improved scar pigmentation, erythema, pliability, texture, height and pruritus. In this review, we present the evolution of laser therapy for hypertrophic burn scars, how different types of lasers work, indications, perioperative considerations and guidelines for practice management.

The Use of CO2 Fractional Photothermolysis for the Treatment of Burn Scars

A recent advancement in the treatment of burn scars has been the use of the carbon dioxide (CO2) laser to perform fractional photothermolysis. In this analysis, we describe our results and patient-reported outcomes with the use of fractional CO2 laser for the treatment of burn-related scarring. We performed a retrospective study of all patients who underwent CO2 laser procedures for treatment of symptomatic burn scars and skin grafts at one accredited regional burn center. Burn injury and laser treatment demographics, as well as complications, are reported. A questionnaire was administered to all patients and included patient-reported outcome measures aimed at understanding the patient experience and their subjective response to treatment. A total of 387 CO2 laser procedures were performed on 131 patients for the treatment of symptomatic burn scars and skin grafts between October 1, 2011, and May 1, 2014 (average, 2.95 procedures/patient; range, 1-11). Average time between injury and first laser was 597.35 days (range, 60-13,475). Average time between laser treatments (when multiple) was 117.73 days (range, 22-514). There were no infections requiring treatment with oral antibiotics. Overall patient satisfaction with laser therapy was 96.7%. Patients reported reductions in neuropathic pain, tightness (contracture), and pruritus (54.0, 50.6, and 49.0%, respectively). Fractional photothermolysis utilizing the CO2 laser is a safe and effective modality for the treatment of symptomatic burn scars, donor sites, and skin grafts. Patient satisfaction with this procedure is high, and complications are low. Significant improvements in scar appearance, pliability, tightness, neuropathic pain, and pruritus were commonly reported.

Hypertrophic burn scar management: what does the evidence show? A systematic review of randomized controlled trials

INTRODUCTION

Hypertrophic scars (HTS) are a source of morbidity for burn survivors and can present with a range of lifestyle-limiting problems. These include pruritus, pain, burning, stiffness, and contractures. Many solutions have been developed, but few have been studied in the form of a prospective, randomized control trial (RCT). Given the importance these RCTs carry in shaping the treatment of burn patients, we sought to systematically and critically review this portion of the burn literature.

METHODS

PubMed was used to perform 2 separate searches with limits that included Humans, English, and Randomized Controlled Trial. A keyword search using "hypertrophic," "Scar," "burn," and "treatment" was cross-referenced with a MeSH subject-heading search using "Cicatrix, Hypertrophic" AND "Burn." Studies were then reviewed and excluded if they did not address management of burn HTS in the non-acute setting.

RESULTS

Two literature searches resulted in a total of 32 articles. Twelve articles were excluded because they were not relevant to the topic (n = 10) or could not be obtained (n = 2). The remaining 20 articles contained 882 patients treated for hypertrophic scars. Breakdown based on topics included laser therapy (58 patients, 2 articles), silicone gel (204 patients, 7 articles), compression garment (236 patients, 4 articles), silicone + pressure (226 patients, 3 articles), topical emollients (58 patients, 2 articles), systemic therapy (62 patients, 1 article), intralesional therapy (18 patients, 1 article), and surgical treatment (20 patients, 1 article). While some articles had favorable conclusions (laser, emollients, surgical, and intralesional therapy) or unfavorable conclusions (systemic therapy), there were conflicting results on silicone and/or compression.

CONCLUSIONS

Despite hypertrophic scars being a common occurrence in burn survivors, both the number of studies and consensus for treatment are limited. Efforts to perform larger, adequately powered RCTs are needed, specifically in the areas of silicone, compression garments, and combination therapy.
