A patient with HCV infection and opioid use disorder begins treatment with direct-acting antivirals (DAAs). Which interaction is most important to monitor with methadone?
Answer: Some DAAs can alter methadone plasma levels, requiring monitoring for withdrawal or toxicity
Certain DAAs (e.g., sofosbuvir/velpatasvir combinations) can affect CYP450 enzymes and P-glycoprotein, potentially altering methadone levels.
Which of the following is a key component of infection prevention in opioid treatment programs (OTPs) administering observed dosing?
Answer: Hand hygiene before and after each patient interaction
Hand hygiene is a foundational infection control measure that must be performed before and after each patient contact in OTPs.
A healthcare worker in an addiction medicine clinic tests positive for latent tuberculosis infection (LTBI). What is the recommended management?
Answer: Treat LTBI with isoniazid or rifampin-based regimen and allow continued work
Treatment of LTBI with isoniazid (9 months) or rifampin-based regimens prevents progression to active TB; work restrictions are typically not required for LTBI.

A patient with opioid use disorder presents with fever, back pain, and elevated inflammatory markers. Which diagnosis must be urgently excluded?
Answer: Vertebral osteomyelitis or epidural abscess
Vertebral osteomyelitis and epidural abscess are serious infections in PWID that present with fever and back pain and require urgent MRI evaluation.
