Homelessness and Inpatient Burn Outcomes in the United States.
Journal of burn care & research : official publication of the American Burn Association
INTRODUCTION: Burn injuries are common in the homeless population. Little is known regarding whether homeless patients experience different outcomes when admitted for burns. We aim to 1) characterize the admitted homeless burn population, and 2) investigate differences in inpatient outcomes between the homeless and non-homeless populations.METHODS: A retrospective cohort study was performed utilizing the Nationwide Inpatient Sample. Adult patients with complete data for burn characteristics were extracted. Variables included demographic, burn, and facility characteristics. Homelessness was identified with International Classification of Disease 9th edition codes. Outcomes were modeled with regression analysis and included length of stay, total operations, charges, disposition, and patient safety indicators.RESULTS: 43,872 encounters were included of which 0.76% were homeless. Homeless encounters were more likely to be male (p<0.001) and Medicaid-insured (p<0.001). Flame and frostbite injuries were more likely (p<0.001), and the mean %TBSA was smaller (15.0 versus 16.8, p<0.001). After adjustment, homeless patients had greater lengths of stay (11.5 vs. 9.6, p=0.046), greater charges ($73,597 vs. $66,909, p=0.030), fewer operations (p=0.016), and three times higher likelihood leaving against medical advice (p=0.002). There was no difference in patient safety indicators or mortality.CONCLUSION: Homeless burn admissions represent a unique cohort that carries a higher comorbidity burden and experiences longer lengths of stay with greater difficulty in disposition. Ironically, these patients accumulate more charges with limited means to pay. Even though no differences were observed in patient safety indicators or mortality, further research is needed to understand how the challenges within this population affect their recovery.

Stem Cell Therapies for Wound Healing.
Expert opinion on biological therapy
INTRODUCTION: Aberrant wound healing is a significant healthcare problem, posing a substantial burden on patients, their families, and the healthcare system. Existing treatment options remain only moderately effective and often fail to promote the closure of non-healing wounds in susceptible populations, such as aging and diabetic patients. Stem cell therapy has emerged as a promising treatment modality, with the potential to restore tissue to its pre-injured state. Of particular interest are mesenchymal stromal cells, which have been shown to accelerate wound healing by modulating the immune response and promoting angiogenesis. Areas Covered: This review provides an overview of wound healing and current methods for the management of chronic wounds, as well as the current state and considerations for optimizing stem cell therapy. Considerations include stem cell types, tissue source, donor selection, cell heterogeneity, delivery methods, and genetic engineering. Expert Opinion: A growing body of evidence has shown that delivery of stem cells, particularly mesenchymal stromal cells, has the potential to effectively improve the rate and quality of wound healing. However, significant additional basic and clinical research must be performed to optimize cell therapy, such as further elucidation of the therapeutic mechanisms of stem cells and standardization of clinical trial guidelines.

Increasing ambulatory treatment of pediatric minor burns-The emerging paradigm for burn care in children.
Burns : journal of the International Society for Burn Injuries
INTRODUCTION: Innovations in topical burn treatment along with a drive toward value-based care are steering burn care to the outpatient setting. Little is known regarding what characteristics predict outpatient treatment of pediatric minor burns and whether there is a temporal trend toward this treatment paradigm.METHODS: A retrospective cohort study was performed using California's Office of Statewide Health Planning and Development linked emergency department and inpatient database (2005-2013). All patients under 18years of age with a primary burn diagnosis were extracted. Using patient and facility level variables, we used regression modeling to evaluate predictors of outpatient burn treatment and temporal trends.RESULTS: There were 16,480 pediatric minor burn encounters during the period. 56.4% were male, 85.3% had <10% total body surface area (TBSA), 76.3% were scald or contact, and 77.3% were at deepest depth 2nd degree. Multiple variables predicted an increased likelihood of discharge home including older age(p<0.001), smaller TBSA(p<0.001), and superficial/partial thickness burns(<0.001). Children of Hispanic and Black race were less likely to be discharged home compared to White and Asian peers(p=<0.001). On Poisson modeling, the incidence rate ratio over the 9-year period for home discharge was 1.004 (95% CI 1.001-1.008, p=0.032).CONCLUSION: Older patients and those with more superficial burns were more likely to be treated as outpatients. Black and non-white Hispanic race was associated with inpatient admission. There is a growing trend toward ambulatory treatment of minor burns in the pediatric population. Further research is needed to assess whether outpatient treatment of pediatric minor burns results in greater readmissions.
