Infectious Disease Advisor: What are potential effects of this lack of awareness?

Dr Meisner: We often keep seeing the same patients come to the hospital and be readmitted or leave against medical advice, and it can be very frustrating or disheartening. And that will keep happening if we are not aware of the real problem. Patients leave against medical advice because they are so uncomfortable from withdrawal symptoms that are not adequately managed or because they are being treated poorly due to possible stigma and biases of healthcare providers.

Lack of awareness or knowledge may lead to patients not being screened for HIV or hepatitis C or B appropriately, or not given appropriate vaccines such as tetanus or hepatitis B. We need to realize that treating the infection is the easy part — we need to address the true underlying cause of infection in this patient population, which is their substance use.

Infectious Disease Advisor: What are some ways in which these knowledge gaps can be addressed?

Dr Meisner: Fortunately, there are already some great ways ID providers can bridge this gap. Getting buprenorphine treatment waived is a huge start. The training lasts 8 hours and is comprehensive. I did the training in person, but it can be completed online as well. [Online training is available through the SAMHSA-funded Providers Clinical Support System] Being able to offer your HIV, HCV, or endocarditis patients a form of medication-assisted treatment is a great way to integrate and improve care.

Getting involved in a hospital’s or city’s opioid task force is another way to learn about the problem on your local level and see what steps are being taken already. It is also invaluable to talk to and collaborate with other departments — for example, social work, psychiatry, emergency medicine, cardiothoracic surgery — that are seeing this problem. Another idea is to reach out to the syringe exchanges and methadone clinics in your community and see if there is a way to collaborate on pre-exposure prophylaxis (PrEP) programs, as well as HIV and HCV screening and treatment. Often multiple people are interested in or working on the same problem, but they may not yet have been connected to each other.

As a fellow I was presented with another possible mechanism to close those knowledge gaps: I completed a Fellow Immersion Training Program in Addiction Medicine. It was a great training course that taught me not only about addiction, but introducing participants to syringe exchange vans, naloxone training, Alcoholics Anonymous and Narcotics Anonymous meetings, and meetings with people in recovery. Just as important, there was mentorship on conducting research in this field.

Infectious Disease Advisor: What are some of the key lines of research currently being conducted in this area, and what are the remaining needs?

Dr Meisner: There have been many great publications related to understanding how big an effect the opioid epidemic is having in the ID field. This includes understanding the trends and outcomes related to endocarditis, such as in the article published by Dr Asher Schranz in the Annals of Internal Medicine, which examined endocarditis trends in North Carolina.5 There has also been research looking at how hospitals are doing with addiction interventions.6

In terms of HIV and HCV work, there have been studies showing successful treatment outcomes for HCV in people who inject drugs.7 In addition, there have been studies looking at PrEP treatment in this population and barriers and implementation of PrEP.8,9

I think continuing research in these areas is important, but also looking at innovative ways to engage and treat this patient population. I would love to see more research that looks at novel ways to treat systemic bacterial infections in this population or more implementation science research to integrate HCV and HIV care into new environments such as methadone clinics and syringe exchanges.
