BACKGROUND: Burns are a primary cause of mortality along with the severe physical and psychological morbidities in patients and their families. Such kinds of injuries bring about considerable financial burdens due to the treatment processes and sequels. The present study aims to investigate the factors that affect the mortality of burns. METHODS: The archives files of the patients admitted because of burn injuries in our burn centre between September 2008 and December 2016 were examined in this study. Some of the lab values, such as age, sex, percentage of total burn surface area (TBSA), referral status, burning site, degree of burns, time of admission to hospital, aetiology of burning, blood and blood products collection, complete blood count, routine biochemistry, coagulation parameters, C-reactive protein (CRP), sedimentation rate, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), were examined while evaluating the patients' mortalities. RESULTS: A total of 133 patients were included in this study. The patient's age (p=0.001), the degree of burns (p<0.001), surface area of burns (p<0.001), the time of hospital admission (p<0.001), burning aetiology (p=0.006), erythrocyte suspension, fresh frozen plasma, along with the administration of albumin transfusion (p<0.001), mean platelet volume (MPV) (p=0.028), NLR (p<0.001) and PLR (p<0.030) values were found to be associated with mortality in patients with burns. CONCLUSION: In this study, age, burn grade, TBSA, hospital admission time, burn aetiology, erythrocyte, fresh frozen plasma and albumin transfusion, MPV, NLR and PLR values were found to be associated with mortality in patients with burns. With this study, it is possible to produce the treatment guidelines to reduce mortality by taking these parameters into consideration, which were determined to be associated with mortality while evaluating the patients with burns.
