Pharmacies are key sources of medication information for patients, yet few effectively serve patients with low health literacy. The Agency for Healthcare Research and Quality (AHRQ) supported the development of four health literacy tools for pharmacists to address this problem, and to help assess and improve pharmacies' health literacy practices.This study aimed to understand the facilitators and barriers to the adoption and implementation of AHRQ's health literacy tools, particularly a tool to assess a pharmacy's health literacy practices.
