56 Reduced Length of Stay with Autologous Skin Cell Suspension Reduces Burn Injuries
Abstract Introduction Burn injuries remain a surgical challenge with few recent innovations. Grafting with split-thickness skin grafts (STSGs) has been the standard of care for decades. Although shown to have mortality benefits, STSGs are associated with significant morbidity in the form of pain and additional open wounds. For years, surgeons have looked for ways to decrease this associated morbidity. To that end, autologous skin cell suspension (ASCS) is a recently FDA-approved point of care regenerative medicine technology that reduces donor skin requirements without compromising clinical outcomes. Our study evaluated the cost and length of stay comparing STSG alone versus ASCS. Methods We obtained IRB-approval for single institution, retrospective chart review of patients age >14 years admitted with burn injuries from March 2018 – September 2018. Primary outcome was length of stay/%TBSA for patients undergoing STSG alone as compared to patients undergoing ASCS. The 2016 American Burn Association National Burn Repository (NBR) was used to benchmark LOS/%TBSA. Age, percentage burn injury (TBSA), LOS, mortality, and number of surgeries were reviewed. Student’s t-test was used to assess statistical significance of intragroup analysis. Results 36 patients were treated with ASCS in combination with meshed autografts for full-thickness acute burn injuries. 37 patients were treated with STSGs at our center. Mean age and %TBSA was 45.2 years and 6.6% for the STSG group and 46.0 years and 18.6% for the ASCS group. The LOS/%TBSA for the STSG was 1.72 versus 1.19 for the ASCS patients (p-value=0.02). The NBR predicts a LOS/%TBSA of 3.38 and 3.42 for the STSG and ASCS groups. Patients in the STSG group and ASCS group had statistically similar surgeries and mortalities. Conclusions Burn injured patients treated with ASCS had a decreased LOS/%TBSA when compared to both the STSGs and NBR predictions. ASCS is a novel technology allowing for point-of-care treatment that may decrease LOS for burn injured patients and should be considered as an adjunct to traditional techniques for burn patients. Applicability of Research to Practice Reduced length of stay compared to traditional burn care.
