A qualitative study of injection and sexual risk behavior among unstably housed people who inject drugs in the context of an HIV outbreak in Northeast Massachusetts, 2018.

BACKGROUND

To investigate the underlying causes of a sudden increase in HIV among people who inject drugs (PWID) and initiate an appropriate response to the outbreak, we engaged in in-depth qualitative interviews with members of the PWID community in Lawrence and Lowell, Massachusetts.

METHODS

We interviewed 34 PWID who were currently or recently unstably housed, then transcribed interviews and coded transcripts, grouping codes into categories from which we identified key themes.

RESULTS

Participants described a heightened threat of overdose prompting PWID to inject together, increasing opportunities for sharing injection equipment. There were misunderstandings about safe injection practices to prevent HIV transmission and a low threshold for injection-related risk taking. Stigma regarding HIV prevented conversations about HIV status. Less thought was given to sexual risks than injection-related risks for HIV transmission.

CONCLUSIONS

We found multiple facilitators of HIV transmission. Additional HIV education and prevention interventions focusing on both injection and sexual risk practices would benefit this population, in addition to structural interventions such as increased access and availability of syringe service programs.
