Abstract
Pseudomonas aeruginosa is one of the most common causes of diabetic foot infection globally. This study aimed to determine the global distribution of P. aeruginosa isolated from diabetic foot ulcer infection. PRISMA procedure was used to perform the current systematic review and meta-analysis. The Web of Science, MEDLINE/PubMed, Scopus, and other databases were searched for studies published in English from 2000 to 2022. Data was analyzed using the Comprehensive Meta-Analysis software (CMA). Keywords and MESH phrases included Pseudomonas aeruginosa, diabetic foot ulcer, P. aeruginosa, and diabetic foot infection. As a result of this review, 16.6% of diabetic foot wound infections were caused by P. aeruginosa. About 37.9% of strains were multidrug resistant (MDR). P. aeruginosa infection rates in diabetic foot ulcers ranged from 0.5 to 100% globally. In total, the prevalence rates of P. aeruginosa in diabetic foot ulcer infection from Asia, Africa, and Western countries were reported at 18.5%, 16.3%, and 11.1%, respectively. Data have shown that the prevalence of P. aeruginosa, particularly MDR strains, isolated from diabetic foot ulcer infection was relatively high; inherent resistance to antibiotics is also high; the wound either does not heal or if it does, it will be delayed. Therefore, timely treatment is essential.
