Antibiotic guidelines coupled with selective reporting of antibiograms

Area of Science:

• Infectious Diseases
• Clinical Microbiology
• Healthcare Management

Background:

• Antibiotic resistance necessitates strategies to optimize antibiotic use.
• Healthcare facilities require robust guidelines for appropriate antimicrobial prescribing.

Purpose of the Study:

• To evaluate the impact of internal guidelines combined with selective reporting of antibiotic susceptibility tests (srAST) on antibiotic adequacy.
• To assess the effectiveness of these interventions in improving antimicrobial prescribing practices.

Main Methods:

• A prospective study was conducted in three clinics over a 6-month period.
• Internal guidelines were updated, and srAST was implemented.
• Bacterial specimens, empirical antibiotic therapies (EAT), and documented therapies were analyzed for adequacy.

Main Results:

• A total of 168 antibiotic prescriptions were analyzed.
• Adequacy rates were 47% for EATs and 92% for documented therapies.
• A statistically significant correlation was found between guideline compliance and srAST use (p=0.02).

Conclusions:

• The combination of internal guidelines and srAST significantly enhances antibiotic adequacy.
• This integrated strategy is effective in optimizing antimicrobial prescribing in healthcare facilities.
