ObjectivesThis study describes harm reduction and health services provided by U.S syringe services programs (SSPs) in 2019 and changes in provision of those services in 2020. MethodsSSPs were invited to participate in the Dave Purchase Memorial survey in August 2020. We collected programmatic data on services provided in 2019 and at the time of the survey in 2020. We conducted descriptive analyses using Chi-square and McNemar’s tests. ResultsAt the time of the survey, > 60% of SSPs reported increased monthly syringe and naloxone distribution and expansion of home-based and mail-based naloxone delivery in Fall 2020 compared to 2019. Approximately three-quarters of SSPs decreased or stopped providing on-site HIV and HCV testing. Nearly half of SSPs offering on-site medications for opioid use disorder (MOUD) in 2019 increased provision of MOUD in 2020. The proportion of SSPs offering on-site mental health care services and primary care services statistically significantly decreased from 2019 to Fall 2020, but telehealth offerings of these services increased. ConclusionsMany SSPs that offered health services in 2019 and remained operational in 2020 increased telehealth provision of mental health and primary care services, increased MOUD provision, and expanded harm reduction services, but most SSPs reduced or stopped on-site HIV and HCV testing. Sustaining SSP growth and innovation is paramount for preventing overdose deaths and HIV/HCV outbreaks after the deadliest year of the opioid epidemic in 2020.
