Episode 224: Community Health Workers

Dr. Arreaza: Today we will discuss a topic that, frankly, every single person listening, whether you're a medical student, a resident, a nurse, a family doctor, or any primary care provider, needs to really understand. We're talking about community health workers (CHWs). We are joined by our stellar medical student; you may be familiar with her voice from previous episodes about insomnia. Moira, welcome, please introduce yourself.

Moira: I want to be upfront about why Community Health Workers matter to you specifically. If you've ever felt frustrated that your patient with uncontrolled diabetes keeps missing appointments because they can't get a ride, or that your heart failure patient was readmitted because nobody checked whether they could afford their medications, then you already understand the problem that CHWs are designed to solve.

Dr. Arreaza: We're going to give you the definition of a CHW, the evidence behind their effectiveness, how they fit into your care team, the return on investment, and practical steps for integrating them into your practice. We have pulled information from a lot of peer-reviewed sources, and we want to share them with you. So, Moira, let's start with the basics. What exactly is a community health worker?

Moira: Great question, and it's one that even literature struggles with, because there are so many titles for this role. Community Health Worker is an umbrella term that encompasses more than 20 different titles including outreach workers, promotores or promotoras de salud, community health representatives, lay health workers, peer educators, patient navigators, and many more. The American Public Health Association defines CHWs as frontline public health workers who are trusted members of or have an unusually close understanding of the communities they serve.

Arreaza: And that trust is so important in health care. CHWs are not physicians. They are not nurses. They do not diagnose or prescribe. But they are like a bridge connecting the medical environment, social services, and the community to reduce gaps in healthcare delivery.

Moira: Exactly. In the United States, the role was formally recognized in the 2010 Patient Protection and Affordable Care Act, which includes several sections highlighting the key roles CHWs play in achieving important goals of healthcare.
