Background

Percentage of body surface area (TBSA) represents an evaluation of burns patients aiding initial resuscitation therapy. The aim of this study was to explore the relationship between the mechanism of burn injury, TBSA and length of hospital stay (LOS).

Methods

This was a retrospective study of 409 patients (126 children, 283 adults) admitted to the Royal Hobart Hospital Burns Unit, Tasmania, between July 2010 and June 2014. Data was obtained from the Burns Registry of Australia and New Zealand and burn mechanism was compared to TBSA affected and LOS. Statistical calculations were performed using SPSS with significance level of 0.05.

Results

The adult population had a higher proportion of flame burns (105/283) whereas the paediatric population had a higher proportion of scald burns (70/126).  In both adult and paediatric populations we found a correlation between burn mechanism and TBSA. Flame burns induced the highest average TBSA (5.4% adult, 4.4% paediatric, p < .001, r2 = .086). In the adult population there was a correlation between TBSA and LOS.

In the paediatric population there was a correlation between burn mechanism and LOS, and between mechanism and TBSA (p<0.001, r2 = 0.351), but no correlation between TBSA and LOS.

Conclusion

These findings support the hypothesis that flame burns are associated with a higher percentage of TBSA affecting the length of hospital admission. This evidence is relevant for medical professionals performing initial assessment of patients presenting to hospital with burn injuries.
