About Us

Advancing antimicrobial stewardship through evidence-based staffing solutions.

Our Mission

SPARC (Stewardship Personnel Required for Antimicrobial Stewardship Programs Resource Calculator) was developed to address the critical need for evidence-based staffing guidance in healthcare institutions implementing Antimicrobial Stewardship Programs (ASPs).

Our mission is to provide healthcare administrators and stewardship teams with data-driven tools that optimize staffing resources, improve patient outcomes, and ensure the effective implementation of antimicrobial stewardship initiatives.
