Healthcare vs. Public Health: What's the Difference?

The material contained in this blog is for informational purposes only and is not to be interpreted as advice or guidance.

The short answer: Healthcare generally focuses on individual patients and the services and care they receive, while public health centers on protecting and improving the health of entire populations and communities.^1,2 If you're drawn to a field focused on supporting health and well-being, understanding that distinction may help you figure out which field fits your interests.

In this article, we'll look at what each field involves, how they differ, where they overlap, and how each may connect to further education.

What Is Healthcare?

Healthcare covers a wide range of work, and not all of it involves direct, hands-on contact with patients. According to the U.S. Bureau of Labor Statistics, medical records specialists, for example, compile and maintain patient files, assign codes for diagnoses and procedures, and safeguard the confidentiality of patient records. Even though they don't provide direct patient care themselves, they work closely with registered nurses and other healthcare workers, meeting with them regularly to clarify diagnoses or gather additional information.¹

That's true of healthcare more broadly. Some roles are entirely hands-on and patient-facing, while others, like medical records specialists, operate more behind the scenes, handling the records, coding, and administrative work that keeps a healthcare setting running. Both are considered part of the same field.¹

What Is Public Health?

At its core, public health is a scientific discipline focused on safeguarding and advancing the wellbeing of communities. That mission plays out through several channels: encouraging healthier ways of living, studying how to prevent disease and injury before they occur, and identifying and responding to outbreaks of infectious illness. What sets this apart from one-on-one care is scale. Public health works on behalf of groups of people rather than individuals, and those groups can range from a single neighborhood up through an entire nation or region.²

Public health professionals may work to promote healthier communities by supporting education, research, and policy initiatives that improve access to health information and resources. That work takes shape through educational programs, policy recommendations, and research, often carried out behind the scenes but with real reach: Public health efforts have been associated with improvements in life expectancy and reductions in disease across populations.²

How Healthcare and Public Health Differ

The clearest distinction between the two is who and what they're built around:

• Who's served: Healthcare includes people who work directly with patients, as well as those who support that care without direct patient contact, such as staff who maintain medical records.¹ Public health focuses on entire populations and communities, not any one person at a time.²
• How the work happens: Healthcare is delivered through a mix of direct, hands-on clinical work and the administrative and support work that keeps those systems running.¹ Public health works through education, policy, and research aimed at prevention.²
• Scale of impact: Healthcare's reach centers on the people receiving care in a given setting.¹ Public health's reach can span a neighborhood, a city, or an entire region or country.²

Many healthcare professionals, including physicians and nurses, provide direct care to individual patients and meet their individual needs, while public health professionals work to prevent large-scale health problems from happening in the first place.²

Where Healthcare and Public Health Overlap

Despite their different focuses, healthcare and public health share the same underlying goal: supporting people's health and well-being. Both rely on trained professionals working within organized systems, and both play a role in preventing and responding to health problems, whether that's a healthcare provider treating an infectious disease in a patient or a public health professional working to detect and contain that same disease at a population level.^1,2

Choosing Between Healthcare and Public Health

Deciding which field fits may come down to where you'd rather focus your energy. If delivering care and services within a healthcare setting interests you, whether through direct patient contact or the administrative work that supports it, the healthcare field may be the closer fit.¹ If you're more interested in protecting and improving health at a population level, through research, policy, and education aimed at entire communities, public health may be the direction to explore.²
