Why is Population Health Important?

Value-Based Care

You’ve been working in the healthcare profession for some time now. While you have a good understanding of the fundamentals of your work, whether in a general practice or specialty, you are only beginning to become acquainted with the topic of population health. As the nation continues to work out the details of making health care services more widely available to all, issues of population health become all the more important.

Definition of Population Health

Population health can be viewed as a collection of the health outcomes of any given group of individuals, with attention being paid to how these outcomes are distributed inside the group. When you are moving a population toward complete coverage for every person, such as through exchanges or a single payer system, population health details will inform decisions of a financial nature as well as logistics, policy and surveillance matters.

Health outcomes can vary between different groups in a population for a number of reasons, including socioeconomic differences (treatment and outcomes compared in low-income neighborhoods and the most wealthy cities can be quite different, for example).

Population Health vs. Public Health

Any discussion of population health will need to account for its differences with public health.

Population health has to do with examining a wide variety of groups of people (such as comparing the incidence of diseases between people of different races, age groups, or living in different ZIP codes. On the other hand, public health looks at the health of an entire population.

You might want to see what the average outcomes are for people who work in different professions, such as respiratory illness comparisons for coal miners versus office workers, or the prevalence of diseases among vaccinated populations versus groups where parents withhold vaccinations because of feared side effects. This is an example of population health that most people are familiar with.

Public health by definition affects all members of the public. So, medical issues related to the environment are good examples of scientists working on the public’s behalf. They will track ailments caused by pollution in the water or air that anyone could be affected by, for example.

Communicable diseases such as the flu or dangerous pathogens that researchers study in locked laboratories under heavy security are aspects of public health, with researchers banding together to develop the current year’s influenza vaccination or setting policy about quarantining passengers from countries where an outbreak is occurring.

If it’s been a while since you gave much thought to population health, read on for an overview about its importance in modern society.

Why Population Health Matters

There are a number of reasons why population health should matter to all of us.

To begin, at the heart of population health is the fact that it is people-focused. The more we can do to improve the health of our fellow humans, the more we lift up all aspects of society (healthier populations can accomplish more than ailing populations, after all), including not having to spend as much money on therapeutic interventions. This assumes that the advances in public health are resulting from improvements in preventative care, diet and exercise.

People are expecting better care. They are spending more of their earnings on healthcare delivery, from physicians to lab tests to their prescriptions. Medical science must deliver commensurate treatment.

The goal is to provide for better patient satisfaction (on the individual level) while also seeing better health in entire groups as the costs of care go down thanks to efficiencies.

Population health studies lead to our being able to provide improved access to care. And when patients receive care when they need it, instead of later during emergency conditions because of neglect (such as because patients lacked health insurance and use emergency rooms instead of a primary care physician), less stress is placed on these vital services.

A focus on population health also promotes better patient engagement. You can expect to see patients feeling empowered so that they can better manage their own health.

Risk Stratification Is a Necessity

Risk stratification involves dividing patients into separate groups which the providers divide them into according to details such as their medical history, overall lifestyle, and their current health signs, as noted by a report from HIT Consultant.

Risk stratification is seen as necessary for the following reasons:

It helps providers predict risks of illness in different groups of patients. Those groups that grow sicker instead of improving their health can be singled out for special attention.

Identifying patient-specific risk factors will help doctors come up with individualized, custom-made care plans instead of resorting to a less effective cookie-cutter approach.

With the risks more clearly defined by groups, medical care providers can better understand their patient population and therefore determine how to best allocate their resources, from staffing to medications and equipment that must be kept on hand for that particular group.

Healthcare Technology Can’t Do it All

It’s tempting for us to rely on our technology, including computers and software systems to take care of much of the drudgery of our daily work requirements. But you should keep in mind that all our healthcare technology cannot replace people and their informed judgment and combined experience treating members of the public.

While a sophisticated EHR system can be instrumental in helping staff members record and save patient data, it cannot yet make informed decisions or develop any form of custom care regimens based on population data and emerging trends identified by statisticians. This process is in fact still manual and needs to be done by a physician or doctor.

The subject of population health is going to be of increasing importance going forward, especially as more medical practices provide diagnosis and treatment statistics and other information electronically to public health researchers. Keep in mind that population health by its very nature is focused on people and it involves professionals assessing populations in terms of risk stratification.

Key Takeaway:

  • Population health is something that staff at all medical practices should be aware of.
  • Population health has to do with the health status of a particular group of people and is distinct from public health, which concerns the health of everyone (all members of the public).
  • Population health is significant because it is focused on the health of ordinary people.
  • Professionals must take into account risk stratification when considering the state of population health.
  • Being able to predict risks helps medical care providers deliver a better standard of medicine.
  • You cannot rely on medical applications such as electronic health record software. Physicians must be involved in making decisions about population health.

While software and computer systems play a big role in population health, doctors must be involved in such areas as making decisions and coming up with care regimes. If you don’t feel quite up to speed on all things having to do population health, click here for a handy infographic on the topic.
