We conducted an observational population-based study utilizing a telephone-based secret shopper methodology. Researchers called all 198 unique retail pharmacies in Hawaii on December 2013–June 2014, representing themselves as patients and physicians.
Only 2.6% of pharmacies had UPA immediately available, though 22.8% reported ability to order UPA. In contrast, 82.4% reported immediate availability of LNG-ECPs. No significant difference in availability was reported to patients and physicians.
Availability of UPA is limited and significantly lower compared to LNG-ECPs. The study period did overlap with a change in distributor for UPA, likely capturing some disruption of the supply chain.
Systems-based interventions are needed to address barriers to obtaining UPA.
