Epidemiological analysis of burn patients in East Bulgaria

Objective

The purpose of the study was to identify the basic epidemiological characteristics of burn patients in East Bulgaria, as well as to analyze trends in burns in the region over the last decade.

Methods

Retrospective data of burn patients treated at Military Hospital-Varna, in the period January 2002–December 2011, was reviewed and statistically interpreted in terms of patients and burn demographics; etiology; place of incidents; hospital stay and mortality. Trends were observed for the entire period and comparative analyses of patients’ data were made between two periods: first – 2002–2006 and second 2007–2011.

Results

A total of 2627 burn patients, median age 41 years (IQR 9–61) were admitted to our burn unit. For the entire period the most affected age groups were ≤4 years (21.6%) and ≥65 years (21.1%). Hospitalized patients increased in the second period (n = 1701) compared to the first one (n = 926), while the size of total burn surface area decreased (first period – 9.8% vs. second period – 10.6%). Scald (51%) and flame (23.8%) were the most frequent aetiological agents for both periods. Work related burns reduced in the second period (9.4% vs. 4.9%), while home burns (90.6 vs. 95.1%) increased. Hospital stay declined from 17days (2002–2006) to 7days (2007–2011), whereas mortality rate slightly increased (first period – 2.3% vs. second period – 3.6%).

Conclusion

Burns remain a significant health problem in Bulgaria. The future preventive actions should take into account the observed changes in burn demographics and target the most vulnerable groups.
