Surveillance of carbapenem resistance in Asian countries: a systematic review and meta-analysis.

Introduction: Carbapenems are used to treat multidrug-resistant organisms as last-resort antibiotics. Resistance to carbapenems is an emerging public health threat worldwide, with alarming reported rates in Asian countries. To minimise further spread of resistant strains and guide interventions, it is important to understand the prevalence rates and causative molecular determinants. Therefore, the systematic review and meta-analysis arising from this protocol will aim to comprehensively describe the available surveillance data on carbapenem resistance in Asian countries to provide an in-depth overview of the carbapenem resistance status in this region.

Methodology and analysis: A systematic review and meta-analysis will be conducted via PubMed, ScienceDirect, Cochrane Library and Web of Science databases. Additional articles and grey literature will be searched in Google Scholar, OpenGrey and Google Chrome by manually searching the reference lists of selected studies. The review question was designed according to components in the ECLIPSE (E-expectations, C-client, L-location, I-impact, P-profile and S-service) framework. Studies conducted with samples other than clinical samples will be excluded. Only original articles published in the English language will be included. The Joanna Briggs Institute critical appraisal tool will be used to assess the quality of the included studies. A random-effects meta-analysis will be performed if the data are sufficiently homogenous. Heterogeneity between studies will be assessed via the I² statistic. The subgroup analysis will be performed considering the type of sample, pathogen type, region/country where the studies were conducted and genetic determinants.

Ethics and dissemination: As this study is conducted on the basis of published data, ethical approval is exempt. The findings of this study will be disseminated in a peer-reviewed journal with the intention of providing summarised data on the globally emerging threat of carbapenem resistance and emphasising the need to introduce alternative, more effective treatment options.
