Contemplating a Career in Burn Surgery: Data From the 2016 Burn Physician Survey.

There is a paucity of information in the peer-reviewed literature characterizing the current burn surgeon workforce and compensation potential, and, in a parallel topic, training opportunities and recruitment methods. What does exist documents minimal exposure to the field and surgeon shortages. A comprehensive survey was created to address 1) the demographics of current burn surgeons in practice, and 2) the structure of burn centers training models. Finally, three questions were asked regarding job satisfaction. With a response rate of 23%, demographics reflect representative involvement across the age spectrum. The majority of respondents (73.9%) had training in general surgery, with subsequent postgraduate training primarily in surgical critical care or burn fellowships. Two-thirds of respondents have active practices, cover multiple specialties, and take multispecialty call throughout the month. A variety of models are used to calculate compensation. The vast majority of burn centers train residents: general surgery residents (89%), plastic surgery residents (63%), and emergency medicine residents (32%), most of whom are in their first 3 years of training. The majority of respondents would become a burn surgeon again if they had to do it over and would recommend it to young surgeons as a career. A representative sample of burn surgeons from across North America sustains practices in similar ways. Access to the next generation of surgeons is at an early period in training (PGY1-3) which may prove valuable as surgical education evolves. Overall, burn surgeons express good job satisfaction, a significant point of interest as attention turns towards succession planning.

A multimodal assessment of melanin and melanocyte activity in abnormally pigmented hypertrophic scar.

Using a validated swine model of human scar formation, hyperpigmented and hypopigmented scar samples were examined for their histological and optical properties to help elucidate the mechanisms and characteristics of dyspigmentation. Full-thickness wounds were created on the flanks of red Duroc pigs and allowed to heal. Biopsies from areas of hyperpigmentation, hypopigmentation, and uninjured tissue were fixed and embedded for histological examination using Azure B and primary antibodies to S100B, HMB45, and α-melanocyte-stimulating hormone (α-MSH). Spatial frequency domain imaging (SFDI) was then used to examine the optical properties of scars. Hyperpigmentation was first noticeable in healing wounds around weeks 2 to 3, gradually becoming darker. There was no significant difference in S100B staining for the presence of melanocytes between hyperpigmented and hypopigmented scar samples. Azure B staining of melanin was significantly greater in histological sections from hyperpigmented areas than in sections from both uninjured skin and hypopigmented scar (P < .0001). There was significantly greater staining for α-MSH in hyperpigmented samples compared with hypopigmented samples (P = .0121), and HMB45 staining was positive for melanocytes in hyperpigmented scar. SFDI at a wavelength of 632 nm resulted in an absorption coefficient map correlating with visibly hyperpigmented areas of scars. In a red Duroc model of hypertrophic scar formation, melanocyte number is similar in hyperpigmented and hypopigmented tissues. Hyperpigmented tissues, however, show a greater amount of melanin and α-MSH, along with immunohistochemical evidence of stimulated melanocytes. These observations encourage further investigation of melanocyte stimulation and the inflammatory environment within a wound that may influence melanocyte activity. Additionally, SFDI can be used to identify areas of melanin content in mature, pigmented scars, which may lead to its usefulness in wounds at earlier time points before markedly apparent pigmentation abnormalities.

Donor site healing dynamics: molecular, histological, and noninvasive imaging assessment in a porcine model.

Understanding the physiology of donor site healing will lead to advances in how these wounds are treated and may ultimately allow faster healing, more frequent autografting, and more effective care of the burn-injured patient. Unfortunately, a paucity of data exists regarding perfusion metrics over the course of donor site healing. Furthermore, there are no studies that interrelate indices of perfusion with the molecular and cellular processes of donor site healing. Male Duroc pigs were anesthetized and donor site wounds were created using a Zimmer dermatome at a depth of 0.060 inch (1.52 mm). Digital photographs, laser Doppler images, and punch biopsies were obtained before and after excision and on days 2, 4, 7, 9, 11, 14, and 16 until wounds were healed. RNA isolation was performed and quantitative polymerase chain reaction was used to examine differential gene expression over the time course. Formalin-fixed biopsies were embedded in paraffin, sectioned, stained, and examined. Wound surfaces were 83% re-epithelialized by day 16. Perfusion peaked on day 2 then declined, but it remained significantly elevated compared to before excision (P < .05). From day 9 onward, mean perfusion units were not significantly different from baseline (P < .05). Twenty-two representative genes were selected for examination. RNA expression of collagen, tenascin-cytoactin, inflammatory cytokines, remodeling enzymes, growth factors, and Wnt was increased. Inflammatory cells and cytokines were demonstrated histologically. Nuclei per high powered field peaked at day 7 and neodermal thickness increased daily to day 14. A novel porcine model for donor site wound healing that interrelates re-epithelilaizationand perfusion with molecular and cellular indices has been demonstrated.

Critical review of burn depth assessment techniques: part II. Review of laser doppler technology.

The judgment of which wounds are expected to heal within 21 days is one of the most difficult and important tasks of the burn surgeon. The quoted accuracy of 64 to 76% by senior burn surgeons underscores the importance of an adjunct technology to help make this determination. A plethora of techniques have been developed in the last 70 years. Laser Doppler imaging (LDI) is one of the most recent and widely studied of these techniques. The technology provides an estimate of perfusion through the burn wound, the assumption being that a lower perfusion correlates with a deeper wound and, therefore, a longer time to heal. Although some reports suggest accuracy between 96 and 100% and that it does this 2 days ahead of clinical judgment, others have questioned its applicability to clinical practice. This article, the second of a two-part series, has two objectives: 1) a review of the Doppler principle and how the LDI uses it to estimate perfusion; and 2) a critical assessment of the burn literature on the LDI. Part I provides a historical perspective of the different technologies used through the last 70 years to assist in the determination of burn depth. Laser Doppler has brought technology closer to provide a reliable adjuvant to the clinical prediction of healing, yet, caution is warranted. A clear understanding of the limitations of LDI is needed to put the current research in perspective to find the right clinical application for LDI.

Critical review of burn depth assessment techniques: Part I. Historical review.

The assessment of burn depth, and as such, the estimation of whether a burn wound is expected to heal on its own within 21 days, is one of the most important roles of the burn surgeon. A false-positive assessment and the patient faces needless surgery, a false-negative one and the patient faces increased length of stay, risks contracture, and hypertrophic scar formation. Although many clinical signs can aid in this determination, accurate assessment of burn depth is possible only 64 to 76% of the time, even for experienced burn surgeons. Through the years, a variety of tools have become available, all attempting to improve clinical accuracy. Part 1 of this two-part article reviews the literature supporting the different adjuvants to clinical decision making is, providing a historical perspective that serves as a framework for part 2, a critical assessment of laser Doppler imaging.

Digital photography: a technique to optimize reimbursement.

Insurance companies may reject claims because of inadequate documentation. Dictated notes or an electronic medical record provide an accurate and complete documentation of services. In a paper-based medical record system, significant amounts of professional fees are lost because the insurance companies reject claims without copies of the note. It is onerous to provide copies of the daily progress notes and bedside procedure notes to the billing service. Retrospective review of billing records for a 12-month period was performed. One partner took daily digital photos of all progress notes and made these available to be submitted with the claim. The other partner did not use this technique. Both partners dictated procedure notes which were available to the billing service for submission. The Wilcoxon's rank-sum test compared the reimbursement rates which were stratified for dictated procedures vs daily notes and insurance type between the two partners. More than 5000 billing submissions were analyzed. The reimbursement rate for procedures was similar for each surgeon (mean 18-19%). The reimbursement rate for daily progress notes was significantly higher for the surgeon using digital photography (mean 38% vs 29%, P < .05 by Wilcoxon's rank-sum test). Digital photography provides an easy means of documenting services. This provides proof of service to insurance companies and improves reimbursement. The same result could be provided by an electronic medical record, or by onsite billing personnel copying the medical record.

Trauma patients: you can get them in, but you can't get them out.

BACKGROUND: The majority of inpatient trauma care resources are consumed by a small proportion of severely injured patients. METHODS: Hospital lengths of stay (LOS), resource consumption, and postdischarge placement were abstracted from the institutional trauma registry. RESULTS: Patients (n = 4,070) were evaluated by the trauma service during the study period. The overall mean LOS was 4.4 days, and beds were occupied on 18,005 days. Two hundred forty-four (6%) patients remained in the hospital >14 days after injury and occupied beds on 8,560 (47%) days. These patients were older, more severely injured, and required proportionately more intensive care unit and operative care. Injuries to the head, abdomen, and extremities were independently associated with longer LOS. Most patients with longer LOS were placed in long-term acute care or received home nursing care after discharge. CONCLUSIONS: Almost half of inpatient trauma bed-days are occupied by a small proportion of patients with long-term care needs.

Tracking the daily availability of burn beds for national emergencies.

Medical planning for Operation Iraqi Freedom included predictive models of expected number of burn casualties. In all but the best-case scenario, casualty estimates exceeded the capacity of the only Department of Defense burn center. Examination of existing federal-civilian disaster plans for military hospital augmentation revealed that bed availability data were neither timely nor accurate. Recognizing the need for accurate knowledge of burn bed availability, the Department of Defense requested assistance from the American Burn Association (ABA). Directors of burn centers in the United States were queried for interest in participation in a mass casualty plan to provide overflow burn bed capacity. A list of 70 participating burn centers was devised based upon proximity to planned military embarkation points. A computer tracking program was developed. Daily automated e-mail messages requesting bed status were sent to burn center directors at 6 am Central time with responses requested before 11 am. The collated list of national overflow burn bed capacity was e-mailed each day to the ABA Central Office and to federal and military agencies involved with burn patient triage and transportation. Once automated, this task required only 1-2 hours a day. Available burn-bed lists were generated daily between March 17 and May 2, 2003 and then every other day until May 9, 2003. A total of 2151 responses were received (mean, 43 burn centers per day). A system to track daily nationwide burn bed availability was successfully implemented. Although intended for military conflict, this system is equally applicable to civilian mass casualty situations. We advocate adoption of this or a similar bed tracking system by the ABA for use during burn mass casualty incidents.
