In 2021, opioid-related deaths have increased by 96% and continue to be higher than prepandemic levels. In particular, women and gender-diverse individuals face numerous challenges when assessing harm reduction supports, including physical supervised consumption sites, compared with male counterparts. Mobile overdose response services (MORSs) including overdose response hotlines and phone-based overdose response applications are novel virtual overdose response technologies that may help mitigate this issue. This study aims to explore how women and gender-diverse individuals engage with and perceive these services.
