Abstract

Background:

To investigate the potential correlation between the rates of antimicrobial drug consumption and the prevalence of antimicrobial resistance among clinical Acinetobacter baumannii recovered in a tertiary care hospital in Tunisia.

Methods:

The microbiological and epidemiological profiles of A. baumannii infections at the Hospital Sahloul, Sousse, were investigated between 2001 to 2004 and 2012 to 2015 along with the consumption record of broad-spectrum antibiotics.

Results:

Our data showed that extensively drug-resistant A. baumannii (XDRAb) isolates increased from 11.2% to 30.5% between 2012 and 2015 and disseminated endemically for a long time. Furthermore, we evidenced a drastic increase of carbapenem-resistant A. baumannii isolates from 29.5% in 2001 up to 88.6% in 2015 (612/691). This rise could be paralleled with a significant increase in antibiotic consumption over the last 15 years, especially with the sharp increase in the annual consumption of imipenem (r = 0.816 and p <103). A noteworthy correlation between carbapenem use and resistance rate (r = 0.778, p<0.001) was evidenced.

Conclusion:

Feedback of these data to clinicians and decision-makers in the local setting was crucial to promote the rational use of antimicrobials and to raise awareness to strictly implement hygiene measures to limit the spread of these XDRAb isolates, to prevent colonization and subsequent infection.

Keywords: Antimicrobial resistance, Antimicrobial consumption, MDR-Ab, XDR-Ab, DDD/1000 patient-day, Imipenem.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."
