Abstract
ObjectiveThe objective of this study was to update the current status of clinical outcomes in diabetic (type II) and obese (BMI: 30–39.9 kg/m2) burn patients. MethodsWe adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We searched MEDLINE (PubMed), Google Scholar, Scopus, and Embase for studies related to a number of comorbidities and burn outcomes. Search terms for each of these databases are listed in the Appendix. From this search, we screened 6923 articles. Through our selection criteria, 12 articles focusing on either diabetes or obesity were selected for systematic review and meta-analysis. Data was analyzed using the “meta” package in R software to produce pooled odds ratios from the random effect model. ResultsDiabetic patients had 2.38 times higher odds of mortality [OR: 2.38, 95% CI:1.66, 3.41], however no statistically significant difference was found in mortality in obese patients [OR: 2.49, 95% CI: 0.36, 17.19]. Obese patients had 2.18 times higher odds of inhalation injury [95%CI: 1.23, 3.88], whereas diabetic patients did not show a difference in odds of inhalation injury [OR:1.02, 95% CI: 0.57, 1.81]. Diabetic patients had higher odds of complications resulting from infection: 5.47 times higher odds of wound, skin, or soft tissue infections [95% CI:1.97, 15.18]; 2.28 times higher odds of UTI or CAUTI [95% CI:1.50, 3.46]; and 1.78 times higher odds of pneumonia or respiratory tract infections [95% CI:1.15, 2.77]. Obese patients also had similar complications related to infection: 2.15 times higher odds of wound infection [95% CI: 1.04, 4.42] and 1.96 times higher odds of pneumonia [95% CI: 1.08, 3.56]. Other notable complications in diabetic patients were higher odds of amputation [OR: 37, 95% CI: 1.76, 779.34], respiratory failure [OR: 4.39, 95% CI: 1.85, 10.42], heart failure [OR: 6.22, 95% CI: 1.93, 20.06], and renal failure [OR: 2.95, 95% CI: 1.1, 7.86]. ConclusionsDiabetic patients have higher odds of mortality, whereas no statistically significant difference of mortality was found in obese patients. Obese patients had higher odds of inhalation injury, whereas odds of inhalation injury was unchanged in diabetic patients. Diabetic patients had higher odds of failure in multiple organs, whereas such failure in obese patients was not reported. Both diabetic and obese patients had multiple complications related to infection.
