Conducted a retrospective review of all PUA tests from 2014 to 2023.
Linked laboratory data with hospital discharge coding for CAP diagnoses.

7,178 PUA tests performed with a positivity rate of 7.6%.
42% of tests ordered lacked a CAP diagnosis, incurring avoidable costs of €17,000 annually.
87% of positive results did not change antimicrobial therapy decisions.
