Blue light phones as potential locations for deploying public access naloxone kits on a college campus.

Opioid use and the risk of opioid overdose are growing public health concerns for college-aged adults. Naloxone can temporarily reverse opioid overdoses, but only if easily accessible. On most college campuses, "blue light" phones (BLPs)-call boxes topped with a blue light-offer visible access to emergency services. We hypothesized that BLPs would provide potential naloxone access points. A major university campus in Los Angeles, CA. BLP locations were obtained using Google Maps, and the area of campus within a set distance to each BLP calculated. To model effects of loss or diversion, we simulated the random loss of various BLPs. Placing naloxone kits at the 59 BLP locations could provide access within 100 m to 91.5% of the campus. With loss of half of the BLPs, campus access remained above 70%. Naloxone at BLP locations could be accessed from almost all campus areas.
