Vancomycin is a glycopeptide antibiotic that requires close therapeutic monitoring. Prolonged exposure to elevated concentrations increases risk for serious adverse effects such as nephrotoxicity. However, subtherapeutic concentrations may lead to bacterial resistance and clinical failure or death. The most recent Infectious Diseases Society of America publication regarding therapeutic monitoring of vancomycin recommends using area under the curve (AUC)-based monitoring to maximize clinical success. Despite the guideline recommendation for AUC-guided dosing, many institutions still use trough-only monitoring in their practices, including those caring for patients with acute burn injuries. Following burn injury, patients are at a higher risk for infections, multiorgan failure, and pharmacokinetic alterations. The primary objective of this multicenter retrospective study is to determine optimal therapeutic monitoring of vancomycin by comparing clinical success between AUC and trough-based monitoring in patients with burns. MONITOR was a multicenter, retrospective study of patients with thermal or inhalation injury admitted to one of 13 burn centers from January 1, 2017 to August 31, 2022 who received vancomycin. Demographic and clinical course data, including acute kidney injury (AKI) incidence and clinical success, were obtained. Patients were evaluated for clinical success and grouped according to method of monitoring and adjusting doses: AUC vs trough-based monitoring. Clinical success was a composite definition and lack of meeting any 1 of 5 criteria: (1) persistent infection, (2) relapse, (3) antibiotic failure (clinical worsening), (4) AKI, and (5) death. A total of 517 vancomycin courses were assessed from 485 patients. There was no difference in the rate of clinical success between AUC monitored and the trough-only monitored groups. Incidence of AKI was higher in the trough-only group; however, it was not statistically significant after controlling for renal function on admission, past medical history of chronic kidney disease, and concomitant nephrotoxins.

Smoking while using home oxygen leads to explosions, which cause cutaneous burns, death, and loss of property. Thermal fuses interrupt the propagation of ignited oxygen lines and reduce the risk of injury. Prior to mandating thermal fuses for all home oxygen users in the United States, cost-effectiveness analysis should be performed. A Markov model was constructed for suffering a thermal injury while smoking on home oxygen. Societal and Medicare perspectives were adopted, evaluating the costs of a federal policy, including purchasing/shipping thermal fuses to all home oxygen users. Costs included the healthcare required to treat burn patients and extend lives in advanced chronic obstructive pulmonary disease. Cost savings included the avoided property loss. Effectiveness was measured in gains in quality adjusted life years (QALYs). In the status quo, the 10-year societal cost was $28.67 billion compared to $28.36 billion in the policy mandate (saving $305.40 million at 10 years). 1812 QALYs were gained with the policy mandate, yielding, and incremental cost-effectiveness ratio (ICER) of -$160 317. From the Medicare payor perspective, the ICER was $64 981. Deterministic and probabilistic sensitivity analyses showed little variation in the ICER under multiple scenarios. The discrepancy between the dominant ICER for a societal perspective and the cost-effective ICER for a Medicare perspective reflected savings from averted property loss not realized by Medicare. A national policy mandating and paying for thermal fuses for all home oxygen users is dominant from a societal perspective and cost-effective from a Medicare perspective. The US government should adopt such a policy.

Despite the growing incidence of burn injuries globally and the advancements in physical recovery, the psychological aspect of burn trauma recovery remains inadequately addressed. This review aims to consolidate existing literature on posttraumatic stress disorder (PTSD) and depression in adult burn survivors, recognizing the need for a holistic approach to burn recovery that encompasses both physical and mental health. The comprehensive analysis of 156 studies revealed significant variations in methodological approaches, leading to challenges in creating standardized protocols for mental health assessment in burn care. Key findings include the identification of a wide range of psychological assessment tools and a substantial research gap in low- and middle-income countries, where the majority of burn injuries occur. Only 7.0% of the studies assessed interventions for PTSD or depression, indicating a lack of focus on treatment modalities. The studies identified demographic factors, patient history, psychosocial factors, burn injury characteristics, and treatment course as risk factors for PTSD and depression postburn injury. The review highlights the need for early screening, intervention, and attention to subjective experiences related to burn injury, as these are strong predictors of long-term psychological distress. It also emphasizes the complexity of addressing psychological distress in burn survivors and the need for more standardized practices in assessing PTSD and depression specific to this population.

Violence against women is a global public health problem. Centers for Disease Control and Precention (CDC) data show 41% of US women have experienced intimate partner violence. Burn-related violence against women is an extremely confronting form of physical violence. The aim of this study was to describe the frequency, demographics, injury characteristics, and outcomes of women admitted to US burn centers who have experienced burn violence compared to those with accidental burn injuries. 2008-2018 data were comparative statistics were used to describe/compare groups. 54 523 women met study inclusion criteria. 956 (2%) experienced burn violence. Women who experienced burn violence had a younger median [IQR] age (36 [27,48] vs 47 [32,61], P < .0001), were Black/African American (44.5% vs 22.4%, P < .0001), were covered by Medicaid (38.8% vs 21.6%, P < .0001), had a higher median [IQR] %TBSA extent (6.0% [3,15.2] vs 3.0% [1,7.3], P < .0001), a higher proportion with third-degree burns (35.4% vs 28.9%, P < .0001), and a higher proportion with TBSA > 20% (18.2% vs 6.7%, P < .0001). Scald/flame injuries were the most frequent mechanism of injury. Women who experienced violence had a higher median [IQR] length of hospital stay (7.0 [2,18] vs 4.0 [1,11] days, P <.0001), Intensive Care Unit (ICU) stay (8.5 [2,27] vs 4 [2,13] days, P < .0001), and mortality rate (5.7% vs 4.3%, P < .04). The frequency of women who sustained burn violence appears small yet experience worse outcomes. Clinicians should be aware of these demographic/clinical characteristics to provide optimal care to this vulnerable population.

Mental health is a component of care that should be addressed for patients with burns while they are hospitalized. Unfortunately, dedicated burn psychotherapists are rare in burn centers in the United States (US), and it can take months for patients to be seen by a mental health professional after referral. Our burn center has a dedicated licensed clinical social worker who sees patients within 2 business days of referral. She uses cognitive behavioral therapy (CBT), which is designed to alleviate symptoms of anxiety, depression, and acute stress by modifying the individual's maladaptive thoughts. To evaluate the timely use of CBT as a treatment for depression in patients with burns, we measured depressive symptoms before and after psychotherapy. Burn clinic nurses administered the Patient Health Questionnaire (PHQ-9) depression screener as part of standard care. We computed difference scores to determine the change in PHQ-9 scores at both group and individual levels. At a group level, psychotherapy significantly improved symptoms of depression, indicated by a decreased mean PHQ-9 score. On an individual level, half of the patients (50.7%) experienced a meaningful improvement in their symptoms, indicated by a change in their PHQ-9 depression category, while 35.6% showed no change. Although it was not an effective solution for all patients in this study, timely use of CBT could be an important component of burn care for many and should be considered as part of standard care in burn centers across the US.

Etherified Carboxymethylcellulose Matrix (eCMC) is a revolutionary application of carboxymethylcellulose (CMC) in wound care, known for its potential in hemostasis and tissue regeneration. This study aims to investigate the mechanism of eCMC in tissue healing by establishing a rat burn model and administering eCMC as a treatment. The objective is to analyze cytokines and inflammatory mediators using a Cytokine Array and histochemical staining to understand the effects of eCMC on tissue regeneration. A rat burn model was created, and eCMC was applied as a treatment. Tissue samples were collected at multiple time points to assess the expression of cytokines and inflammatory mediators using a Cytokine Array. In addition, histochemical staining was performed to evaluate tissue regeneration factors. eCMC induced the expression of endogenous cytokines, particularly vascular epithelial growth factor and platelet-derived growth factor, while inhibiting inflammatory cytokines such as CINC-1, CINC-2, and MMP-8. This dual action facilitated wound healing and mitigated the risk of infection. eCMC demonstrates promising potential for enhancing skin regeneration. Further research is warranted to delve into the precise mechanism of eCMC's cytokine regulation. In vitro and in vivo studies should be conducted to comprehensively investigate the therapeutic capabilities of eCMC in wound healing.

This quality improvement project at a single institution aimed to increase the proportion of prescribed tube feeds delivered to adult patients in the burn population with greater than 20% affected TBSA. A retrospective chart review was performed on all adult patients with burns from January 2018 to July 2022 with greater than 20% TBSA burns to compare quantitative measures such as length of stay, change in weight, and mean tube feeds delivered over hospitalization. Prospective data collection began in August 2022, when the first intervention was implemented, and continued until July 2023 in the same patient population to serve as a postintervention cohort. Using a multidisciplinary approach, the team implemented 8 interventions, which increased the mean proportion of tube feeds delivered to patients from 43% to 78%, marking a significant increase in nutrition delivered to patients, which is critical for wound healing following burn injuries.

The prevalence of psychological symptoms in burn survivors has been well documented; however, the role of biological sex requires further investigation. This study explored sex differences among burn survivors and examined the impact of sex, age, and total body surface area (TBSA) of the burn injury on the risk of developing posttraumatic stress disorder (PTSD) and depression and, subsequently, the influence of initial risk on symptom outcomes 30 days postinjury. Participants included 374 adult patients enrolled in the Burn Behavioral Health program at a regional Burn Center. T-tests and chi-square tests were conducted to determine differences between sexes on outcome measures. A path analysis was conducted to evaluate relationships between variables of interest. Findings revealed significant sex discrepancies in risk and symptom outcomes. Compared to men, women reported greater total risk scores of developing PTSD and depression (P = .005) early after their burn injury. A subscale analysis showed that women reported greater risk scores for depression (P < .001), but not on PTSD. Women did not report higher depression scores 30 days postinjury compared to men but did report higher PTSD scores than men (P = .020). When sex, age, and TBSA were included in a path analysis, female sex (P = .001), younger age (P < .001), and larger TBSA of the burn injury (P = .024) were associated with greater risk. In addition, risk scores significantly predicted PTSD (P < .001) and depression (P < .001) symptoms 30 days postinjury. Our research shows how sex, age, and TBSA affect the risk of PTSD and depression among burn survivors. It underscores the importance of accounting for sex and age differences in mental health risk, especially in women and younger patients. This emphasizes the urgency of early screening and intervention.
