Hypothesis

What are the risk factors for developing cutaneous injection-related infections among injection drug users?

Conclusion

Female sex, unstable housing, borrowing syringes, requiring help injecting, and daily cocaine use are associated with a higher risk of cutaneous injection-related infections.

Supporting Evidence

  • Female sex was associated with a higher risk of CIRI (AOR = 1.68).
  • Unstable housing increased the risk of CIRI (AOR = 1.49).
  • Borrowing used syringes was linked to a higher risk of CIRI (AOR = 1.60).
  • Requiring help injecting was associated with an increased risk of CIRI (AOR = 1.42).
  • Daily cocaine injection was linked to a higher risk of CIRI (AOR = 1.41).

Takeaway

This study found that some people who use drugs and inject them can get skin infections, especially if they are women, live in unstable housing, or share needles.

Methodology

A longitudinal analysis using generalized linear mixed-effects modeling was conducted on data from the Scientific Evaluation of Supervised Injection cohort.

Potential Biases

Potential social desirability bias due to reliance on self-reported data.

Limitations

The study may not be generalizable to all injection drug users, relies on self-reported data, and could not examine certain behaviors due to low reporting.

Participant Demographics

The cohort included 1065 participants, with 29% being female and a median age of 36 years.
