Pharmacist-Led Diagnostics: A New Frontier in Antimicrobial Stewardship

Area of Science:

• Pharmacology
• Infectious Diseases
• Public Health

Background:

• Global rise in antimicrobial resistance (AMR) linked to inappropriate antibiotic use and diagnostic uncertainty in primary care.
• Pharmacist-led point-of-care testing (POCTs) offers a potential solution to optimize antibiotic prescribing and enhance antimicrobial stewardship (AMS).

Purpose of the Study:

• To review current evidence, regulatory frameworks, and implementation data for pharmacist-led diagnostics and antibiotic management globally.
• To identify barriers and facilitators for the widespread adoption of these models.

Main Methods:

• A comprehensive scoping review of existing literature, pilot studies, feasibility assessments, and service evaluations.
• Analysis of data from multiple countries focusing on pharmacist-led POCTs and antibiotic management.

Main Results:

• Limited high-quality clinical trial evidence exists despite significant policy interest.
• Preliminary findings suggest that POCTs, when integrated with structured clinical pathways, can decrease inappropriate antibiotic prescribing.
• Existing studies are primarily pilot or feasibility work.

Conclusions:

• Widespread implementation is hindered by regulatory fragmentation, workforce constraints, and inadequate monitoring systems.
• Larger, robust clinical trials are essential to evaluate the long-term safety, clinical effectiveness, and AMS impact of these interventions.
