Abstract INTRODUCTION Carbapenem-resistant Acinetobacter baumannii is a complex health problem, causing difficulties in clinical–therapeutic management worldwide. It is of particular concern in Latin America, the Caribbean and China, where it is an emerging health problem. Carbapenemases produced by these organisms inactivate carbapenem antibiotics. Monitoring circulating genotypes’ geographic dispersion contributes to more effective control measures. However, exhaustive studies on carbapenem-resistant A. baumannii are scarce. OBJECTIVES Study the production of carbapenemases in clinical isolates of A. baumannii resistant to carbapenem antibiotics and the geographic distribution of the sequences circulating in China, Latin America and the Caribbean. DATA ACQUISITION We followed PRISMA indications. We carried out a systematic search in Pubmed, BVS and CKNI on papers on A. baumannii and carbapenemases published during 2015–2020 in English, Spanish and Chinese, and selected 29 cross-sectional studies that met the search criteria. Studies were evaluated using JBI Critical Appraisal tools, and quantitative data were collated for meta-analysis using the Metaprop library in Stata15. DEVELOPMENT OXA-type carbapenemases were detected in all studies; among A. baumannii resistant to carbapenem antibiotics, predominant types were OXA-23, OXA-24, OXA-54 and OXA-72; metallobetalactamases were identified less frequently than OXA carbapenemases. Only one clinical isolate producer of Class A carbapenemases (KPC) was identified in Colombia. In total, 41 sequence types were identified; in Latin America and the Caribbean the most common types were: ST79, ST25, ST1 and ST15; in China, the sequences ST195, ST208, ST191, ST368 and ST369 were the most prevalent. ST2 was found in both regions. CONCLUSIONS The most prevalent carbapenemases and sequence types vary by region, indicating different ancestral strains. Microbiological surveillance, antibiotic use optimization, adequate infection treatment and timely control strategies are essential for carbapenem-resistant A. baumannii prevention and control in geographies such as Latin America, the Caribbean and China where such resistance is an emerging health problem.
