State Variation in Uptake of Pharmacy-Based CLIA-Waived Testing: Impact of Laws and Regulations.

Background: Community pharmacies have grown to be an increasingly important provider of CLIA-waived tests, just second to physician offices as the venue with the most waivers. Yet, individual variation is still observed across states with respect to the percentage of pharmacies holding a CLIA-waiver, with a reported range of 10.7% in Massachusetts to 87.9% in Delaware. Objective: To identify how state laws can either impede or enhance access to POCT services by pharmacies by comparing the percentage of pharmacies in each state holding a CLIA-waiver to the legal model for POCT services in each state. Methods: Data from the U.S. Centers for Disease Control and Prevention CLIA Laboratory Search website reported on December 4, 2023, were used to determine the number of pharmacies holding CLIA-waivers in each state. This was then divided by the number of community pharmacies in each state, as reported in the 2023 National Community Pharmacy Association Digest, and then compared with 2 public reports on pharmacy CLIA laws. Results: States categorized as allowing pharmacists to independently perform CLIA-waived tests in public reports actually had a lower percentage of pharmacies with a CLIA-waiver (49.60%) than those categorized as not allowing CLIA-waived tests (60.19%). As many as 10 241 pharmacies hold a CLIA-waiver in states that did not affirmatively report that pharmacists ordering lab tests was allowed. Conclusion: The paradoxical finding is likely a result of the underreporting of pharmacist CLIA-waived testing authority given the complexity of pharmacy law relative to other professions. Simplifying pharmacy law through adoption of a "standard of care" regulatory approach may enhance patient access to POCT services moving forward.
