603 Evaluating real-world national and regional trends in definitive closure in US burn care: A survey of US Burn Centers

Abstract

Abstract Introduction Real-world data is observational data gathered outside of the experimental setting from diverse sources which is analyzed to produce real-world evidence. To better understand the impact of burn center treatment patterns, a national sample survey for real-world data sought to benchmark key burn center practice patterns, resource utilization, and clinical outcomes with national data contained within NBR version 8.0 (NBR). Methods A survey was developed by healthcare economists and burn specialists and administered to a representative sample of US burn centers. The survey collected information across several domains, including: burn center characteristics; patient characteristics including number of patients, and burn size and depth; aggregate number of types of procedures; and resource use such as autograft procedure time, length of stay (LOS), and dressing changes; and costs. Nuanced information was collected on care practices and patient outcomes for TBSA burns under 20%. Survey findings were aggregated by key outcomes (LOS, number of procedures, costs) nationally and regionally. Aggregated burn center data were also compared to the NBR to identify trends relative to current treatment patterns. Results Benchmarking survey results demonstrated shifts in burn center patient mix, with more severe cases being seen in the inpatient setting and less severe burns moving to the outpatient setting. Additionally, an overall reduction in the number of autograft procedures was observed compared to NBR, and time efficiencies improved as the intervention time per TBSA decreases with TBSA increases. Both nationally and regionally, an increase in costs were observed. Conclusions The results suggest resource use estimates from NBR version 8.0 may be higher than current practices, thus highlighting the importance of improved NBR reporting and further research on burn center standard of care practices. This study demonstrates significant variations in burn center characteristics, practice patterns, and resource utilization thus increasing our understanding of burn center operations and behavior.
