Injection drug users (IDU) experience complex barriers to accessing primary medical care which may result in over reliance on emergency health services. Supervised injecting facilities (SIF) aim to address HIV and overdose risks, as well as improve access to primary medical care among IDU. This study sought to investigate IDU perspectives regarding the impact of SIF on access to care and treatment of injection-related infections. Semi-structured qualitative interviews were conducted with 50 individuals recruited from a cohort of SIF users known as the Scientific Evaluation of Supervised Injecting (SEOSI). Audio-recorded interviews were transcribed verbatim and a thematic analysis was conducted. IDU narratives indicate the availability of on-site nursing attention at the SIF facilitated uptake of health services. IDU reported that the facility provided assessment and care of injection-related infections, as well as enhanced access to off-site medical services. The presence of professional nursing personnel within a sanctioned drug consumption setting serves to address social and structural barriers that often impede IDU access to health care. This study emphasizes that the facility enables contact with the healthcare system and thereby helps to facilitate the management of injection-related infections.
