Medication Handling and Storage among Pilgrims during the Hajj Mass Gathering

We aimed to investigate the knowledge and practices of Hajj pilgrims regarding medication storage and handling during the Hajj mass gathering. In this cross-sectional study, adult pilgrims from 30 countries were interviewed using a structured questionnaire during the 2019 Hajj. The study enrolled 1221 participants with a mean age of 50.8 years (SD = 12.5, range = 18-98) and male:female ratio of 1.7:1. Most pilgrims were literate, 50.4% had a university or higher education, and 38% reported at least one underlying health condition. Most pilgrims reported receiving education regarding the proper way to store their medication during Hajj, mainly from physicians (73.7%) and pharmacists (39.4%). Although 68.2% of pilgrims had good knowledge regarding medication storage and the potential effect of inappropriate storage conditions on medications and health, inadequate knowledge and poor practice were identified among some. Level of education, having an underlying health condition and receiving health education on mediation storage were independently associated with good knowledge. Most pilgrims took their medications with them during Hajj, although storage and handling of their medication also varied depending on the stages of their Hajj pilgrimage journey. Improving Hajj pilgrims' awareness and knowledge about appropriate storage and handling of their medications are beneficial in reducing the risk of associated adverse health outcomes, both during Hajj and beyond the mass gathering.
