Indigenous and non-Indigenous Australian children hospitalised for burn injuries: a population data linkage study.

OBJECTIVE To investigate differences in the characteristics of burn injuries leading to hospitalisation of Indigenous Australian and non-Indigenous children in New South Wales.Design, setting: Population-based cohort analysis of linked hospital and mortality data for 2000-2014. PARTICIPANTS 35 749 Indigenous and 1 088 938 non-Indigenous children aged 0-13 years. MAIN OUTCOME MEASURES The external cause of the injury, its anatomic location, total body surface area affected (%TBSA), burn depth, length of hospital stay (LOS). RESULTS 4246 non-Indigenous and 323 Indigenous children were hospitalised for a first burn injury during 2000-2014. A higher proportion of Indigenous than non-Indigenous children were admitted with burns affecting more than 10% TBSA (17% v 12%) and a lower proportion of Indigenous children than of non-Indigenous children were treated at a hospital with a paediatric tertiary referral burn unit (40% v 50%; P < 0.001). The mean LOS during the index admission was almost 3 days longer for Indigenous children than for non-Indigenous children (6.1 days [95% CI, 4.8-7.4 days] v 3.4 days [95% CI, 3.2-3.7 days]; P < 0.001); the difference in LOS was still statistically significant after adjusting for characteristics of the burn and residential location. CONCLUSION The proportion of Indigenous children with burns who presented with burn injuries affecting more than 10% TBSA was greater than for non-Indigenous children. Their mean LOS was also longer; the difference remained statistically significant after adjusting for characteristics of the burn and of residential location.
