Screening for Anthrax Postexposure Antibiotic Prophylaxis-The New York City Approach.

Area of Science:

• Public Health
• Infectious Disease Control
• Emergency Preparedness

Background:

• Antibiotic postexposure prophylaxis (PEP) is crucial for preventing inhalation anthrax after exposure to Bacillus anthracis (B. anthracis) spores.
• Public health authorities manage PEP dispensing during anthrax events using screening algorithms.
• Current algorithms vary significantly between jurisdictions, leading to inconsistent antibiotic recommendations for individuals with similar exposure profiles.

Purpose of the Study:

• To address the inconsistency in antibiotic PEP selection across different jurisdictions.
• To present New York City's specific screening algorithm, planning assumptions, and rationale for question selection.
• To encourage standardization of PEP screening algorithms and public messaging to enhance public health response confidence.

Main Methods:

• Development and refinement of a standardized screening algorithm for antibiotic PEP.
• Detailed rationale for inclusion and exclusion of specific screening questions.
• Comparative analysis of New York City's algorithm against those used in other jurisdictions.

Main Results:

• Significant variability identified in screening questions and antibiotic dispensing decisions among jurisdictions.
• New York City's algorithm aims to standardize antibiotic selection based on clinical appropriateness.
• Exclusion of certain screening questions by other jurisdictions based on relevance and potential for confusion.

Conclusions:

• Inconsistent antibiotic PEP protocols can erode public and professional confidence in public health responses.
• Standardization of screening algorithms and dispensing practices is essential for a unified and effective anthrax response.
• Adoption of refined, evidence-based algorithms can improve the reliability and equity of PEP distribution.
