Antibiotic resistance (ABR) has substantial global public health concerns. This systematic review aimed to synthesise recent evidence estimating the economic burden of ABR, characterised by study perspectives, healthcare settings, study design, and income of the countries.
Global health has improved significantly since the discovery of penicillin in 1928. However, organisms, such as bacteria have become increasingly resistant to many antibiotics in recent years. Although antibiotic resistance (ABR) is a natural phenomenon, the process of resistance is accelerated by overuse and misuse of antibiotics, and intercontinental travel. In the past, resistant infections were associated with hospitals and care settings, but over the last decades, these have been spread in the wider community.
Materials and Methods:
This review is in line with the ‘Preferred Reporting Items for Systematic Review and Meta-Analysis’ (PRISMA) checklist  and is registered to the International Prospective Register of Systematic Reviews (PROSPERO) with the registration number- CRD42020193886. Ethical approval was not required for this study.
This review evidenced that a limited number of studies have been conducted on the economic burden of antibiotic resistance in recent years, as only 29 studies were identified published since January 2016 that included healthcare costs with suitable comparators (i.e., antibiotic resistant vs susceptible infections). Of these, a very limited number of studies were conducted in primary and secondary care settings. MRSA, E. coli and P. aeruginosa were the top three most studied resistant bacteria in recent economic burden studies.
