ABSTRACT
Unhoused (UH) individuals experience burn injuries at a higher rate than domiciled individuals, and have poorer outcomes following injuries. One such mechanism proposed for worsened outcomes is secondary to poor nutrition. Access to proper nutrition and food insecurity are major barriers. Malnutrition has been shown to decrease wound tensile strength, increase infection rates, and prolong healing. The purpose of this study was to understand if albumin and prealbumin could help determine outcomes in UH patients and identify at-risk patients earlier in their hospital course A retrospective chart review was conducted of UH patients from 2015 through 2023 at a large urban safety net hospital. Data collected included admission laboratory values including albumin and prealbumin. Outcomes studied included length of stay, ICU days, ventilator days, and mortality. Data analysis for the effect of albumin and prealbumin included a zero-truncated negative binomial model for length of stay, a negative binomial hurdle model for ICU length of stay and ventilator days, and logistic regression for mortality. 385 patients met inclusion criteria and of these, 366 had albumin and 361 had prealbumin information. Adjusting for age, gender, and TBSA, the fewest days in the hospital and lowest odds of admission to the ICU occurred for those with admission albumin values of approximately 3.4-3.5 g/dL. Each unit (g/dL) decrease in albumin was associated with 3.19 times the odds of death (95% CI 1.42, 7.69). Each unit (mg/dL) decrease in prealbumin was associated with 1.19 times the odds of death (95% CI 1.06, 1.35). Decreased admission albumin and prealbumin levels are associated with worse burn outcomes in UH patients. These nutritional biomarkers may aid in determining which UH patients are suffering from food insecurity at injury onset. Obtaining these values on admission may help burn providers target nutritional goals in their most vulnerable patients.
ABSTRACT
OBJECTIVE: To present a model for integrated global health fellowships in plastic surgical residency training. BACKGROUND: National surveys have found that North American surgical residents have significant interest in international training. While global health training opportunities exist, less than a third of these are housed within surgical residency programs; even fewer are designed specifically for plastic surgery residents. METHODS: The Tsao Fellowship was created through a partnership between Operation Smile, Children's Hospital Los Angeles, Shriners Hospital for Children, and the University of Southern California. Designed for Accreditation Council for Graduate Medical Education accredited plastic surgery residents between their third and fourth years of residency, the fellowship curriculum is completed over 24 months and divided into 3 areas: clinical research, international reconstructive surgery fieldwork, and the completion of a Master of Science in Clinical and Biomedical Investigations. RESULTS: The Tsao Fellowship has matriculated 4 fellows: 3 have graduated from the program and 1 is in the current cycle. Fellows completed 4 to 7 international missions each cycle and have performed an aggregate total of 684 surgical procedures. Each fellow also conducted 2 to 6 research projects and authored several publications. All fellows continue to assume leadership roles within the field of global reconstructive surgery. CONCLUSIONS: Comprehensive global health fellowships provide invaluable opportunities beyond surgical residency. The Tsao Fellowship is a model for integrating international surgical training with global health research in plastic surgical residency that can be applied to other residency programs and different surgical specialties.
