[Ecological consequences of preventive antibiotic prescriptions]

Area of Science:

• Microbiology
• Clinical Pharmacy
• Infectious Diseases

Context:

• Hospital practices involving preventive antibiotic use are critical for managing bacterial resistance.
• This review focuses on surgical antibioprophylaxis and selective digestive decontamination.
• The analysis specifically examines the impact on bacterial flora.

Purpose:

• To assess the ecological impact of preventive antibiotherapy on bacterial flora in hospital settings.
• To review the consequences of surgical antibioprophylaxis and selective digestive decontamination on microbial communities.
• To provide insights into strategies for circumventing the development of bacterial resistance.

Summary:

• Data indicate that surgical antibioprophylaxis requires strict adherence to therapeutic regimens, particularly treatment duration.
• Selective digestive decontamination poses risks of selecting for resistant bacterial flora.
• Mandatory monitoring of intestinal flora during treatment is essential, with strictly limited indications for selective digestive decontamination.

Impact:

• Highlights the importance of judicious antibiotic use in hospitals to combat antimicrobial resistance.
• Emphasizes the need for careful consideration of antibiotic strategies to preserve the natural bacterial flora.
• Informs clinical practice and policy-making regarding the use of preventive antibiotics and the management of bacterial resistance.
