ABSTRACT The principal aim of this study was to describe infection related characteristics of blood stream infections (BSI) in patients with burns. We sought to determine the organisms that caused BSI and factors that could predict the outcome of BSI.
Data was collected on admitted patients with burns from January 1998 to December 2008. Selected information from databases was analysed using SPSS version 17 (SPSS Inc., Chicago). Descriptive, univariate and multivariate analysis was undertaken to determine factors predictive of clinical outcome. The factors analysed by univariate analysis were selected on clinical plausibility. Multivariate analysis used a crosstabs procedure initially to estimate maximum likelihood. Factors that were associated with a p value <0.15 were entered into a binary logistic regression to detect which factors were independent predictors of mortality in BSI and outcome according to specific organisms.
Ninety-nine out of 2364 (4%) patients developed 212-documented BSI. The median time from burn to BSI was 7 (interquartile range 3-16) days. Gram-positive organisms, in particular Methicillin resistant Staphylococcus aureus and Coagulase negative Staphylococci, were the most common bacteria associated with BSI in the first week of hospital admission. The mortality rate for all admissions over the data collection period was 3%. Of the 99 patients with BSI, 13 died giving a mortality rate, in the presence of BSI, of 13%. Univariate analysis found that the factors predictive of P. aeruginosa mortality were inhalational injury, higher total body surface area burns, total days of antibiotic treatment and elevated Acute Physiological and Chronic Health Evaluation (APACHE) II scores. Multivariate analysis identified inhalational injury to be the only factor associated with BSI-related mortality.
Whilst the overall mortality in our cohort was low, the presence of BSI increased this four-fold. Whilst infections caused by Gram-positive pathogens occurred earlier in the patient stay than Gram-negative organisms, the highest mortality was associated with P. aeruginosa infections. This study highlights the negative effects of BSI on clinical outcomes in burn patients.

    ABSTRACT: The objective of this study was to describe nosocomial infection (NI) rates, risk factors, etiologic agents, antibiotic susceptibility, invasive device utilization and invasive device associated infection rates in a burn intensive care unit (ICU) in Turkey. Prospective surveillance of nosocomial infections was performed according to Centers for Disease Control and Prevention (CDC) and National Healthcare Safety Network (NHSN) criteria between 2001 and 2012. The data was analyzed retrospectively. During the study period 658 burn patients were admitted to our burn ICU. 469 cases acquired 602 NI for an overall NI rate of 23.1 per 1000 patient days. 109 of all the cases (16.5%) died. Pseudomonas aeruginosa (241), Acinetobacter baumannii (186) and Staphylococcus aureus (69) were the most common identified bacteria in 547 strains. Total burn surface area, full thickness burn, older age, presence of inhalation injury were determined to be the significant risk factors for acquisition of NI. Determining the NI profile at a certain burn ICU can lead the medical staff apply the appropriate treatment regimen and limit the drug resistance. Eleven years surveillance report presented here provides a recent data about the risk factors of NI in a Turkish burn ICU.

    ABSTRACT: Approximately 2457 research articles were published with burns in the title, abstract, and/or keyword in 2012. This number continues to rise through the years; this article reviews those selected by the Editor of one of the major journals in the field (Burns) and his colleague that are most likely to have the greatest likelihood of affecting burn care treatment and understanding. As done previously, articles were found and divided into these topic areas: epidemiology of injury and burn prevention, wound and scar characterization, acute care and critical care, inhalation injury, infection, psychological considerations, pain and itching management, rehabilitation, long-term outcomes, and burn reconstruction. Each selected article is mentioned briefly with comment from the authors; readers are referred to the full papers for further details.
