The Epidemiology of Burn Injuries in Saudi Arabia: A Systematic Review

Burns are potentially catastrophic injuries that disproportionately affect non-Western countries. We summarize results on the epidemiology of burn injuries in Saudi Arabia of all eligible papers through 2019, specifically evaluating the age and gender of patients, the location and mechanism of injury, burn size and severity, and outcomes. Between July 5 and July 10, 2019, a comprehensive literature review was performed on MEDLINE, EMBASE, Google Scholar, and the Cochrane Library. For this search, "Saudi Arabia," coupled with the search terms "burn," "thermal burn," "flame burn," "chemical burn," "electrical burn," and "contact burn" to identify all abstracts potentially relating to the topic of interest. Eleven studies, encompassing 3308 patients, met eligibility criteria. Younger children (variably defined as <= 10-12) accounted for 52% of all burns. Males outnumbered females by an overall ratio of 1.42:1. About 83% of burns occurred at homes. Scald injuries accounted for 62.4% of injuries, followed by flame-induced burns (28.7%), electrical burns (3.3%), and chemical burns (2.8%). Pertaining to burn extent and severity, 80% to 100% of the burns were limited to <40% total body surface area, while roughly 60% were second-degree burns. Most patients remain in the hospital for 1 to 4 weeks. The overall mortality across studies including patients of all ages was 6.9%, while just 0.76% in the two studies restricted to pediatric patients. Scald injuries involving young children comprise the lion's share of burn injuries in Saudi Arabia. Increased public awareness is necessary to reduce the incidence and severity of these potentially catastrophic injuries.
