Public Health Solutions via Research: Why Study Health Informatics

public health solutions

Imagine a world where diseases are detected before symptoms arise, medical treatments are tailored to an individual’s unique genetic makeup, and patient data is securely shared between providers to enable optimal care. This is the future that health informatics helps create.

Health informatics is the discipline focused on capturing, storing, managing, and analyzing health data to improve medical care, systems, and outcomes. It sits at the intersection of information technology, public health, and healthcare delivery.

For those fascinated by using data, systems, and analytics to tackle public health challenges, a career in health informatics offers a tremendous opportunity to make a difference. Keep reading to learn how health informatics improves lives, why health informatics research matters, and how you can join this fast-growing and exciting field.

Detecting Health Threats Early:

Health informatics research has enabled the development of clinical decision support systems that analyze patient data to provide timely diagnostic and treatment recommendations at the point of care. These systems can even identify concerning trends or outbreaks before they occur.

For example, advanced analytics tools helped health officials detect the rise of lung injuries related to e-cigarette use and COVID-19 earlier than through traditional surveillance methods. This allowed epidemiologists and public health agencies to more effectively coordinate responses.

Professionals pursuing online masters in health informatics programs focus their studies on leveraging data analytics to enable the early identification of health threats. Early detection through health informatics supports better health outcomes.

Empowering Preventative Care:

Many chronic diseases such as heart disease, stroke, and diabetes can be prevented or delayed through healthy lifestyle choices like diet, exercise, and avoiding tobacco. However, changing behaviors is difficult. Health informatics explores how data analytics and digital health tools can motivate patients and empower lifestyle changes to prevent disease.

For example, wearable devices and apps can track physical activity, sleep, diet, and vital signs. Combined with electronic health record (EHR) data, these tools enable providers to identify health risks sooner and engage patients in their health journey through personalized recommendations and nudges.

Health informatics will continue uncovering innovative ways that data and technology can empower patients and providers to drive the prevention of chronic illness and catch emerging risks early. This prevents costly diseases and empowers people to live healthier lives.

 Optimizing Treatments:

Every individual responds differently to medications and therapies based on their genetics, health history, demographics, and more. Health informatics allows medical treatments to become more precise and optimized through advanced data analytics. With sophisticated algorithms, large sets of population health records can be analyzed to determine which treatments have the best outcomes for specific patient subgroups.

For example, researchers are using big data techniques to uncover how genetics and biomarkers can guide personalized treatment plans for complex diseases like cancer. Informatics also enables aggregating many years of population health data to understand the long-term effects of therapies, detect safety issues sooner, and identify ways to improve the quality of care overall.

By tapping into large volumes of health data, informatics helps reveal optimal and personalized treatments for patients. This leads to better health outcomes, lower risks of side effects, and more cost-effective care across populations.

Improving Access:

Telehealth platforms and remote monitoring technologies powered by health IT systems are expanding access to top providers for patients in rural areas or with limited mobility. With telemedicine, they can conveniently ‘see’ doctors through video visits without traveling long distances. Health informatics research will continue improving telehealth technologies and exploring innovative care delivery models to reach underserved communities.

Health informatics also empowers patients to directly access their own medical data through patient portals, personal health record systems, and mobile apps. This open access helps individuals become more engaged partners in managing their health. Informatics tools further improve access by enabling secure data sharing between healthcare facilities, so patient information is available wherever they seek treatment.

By increasing connectivity through telehealth and health information exchange, health informatics knocks down barriers to care access. This is especially impactful for rural, disabled, and elderly populations. Informatics gives them greater control over their health while improving care coordination through data availability.

Enhancing Health Equity:

Health information technology can help provide better care to people who aren’t getting what they need. Researchers use data to see where the gaps are. For example, the data might show certain clinics don’t have enough interpreters for non-English speaking patients. Or it may show some communities aren’t getting preventive health screenings as much as others.

These insights enable the development of targeted solutions like improved translation services, culturally competent community outreach programs, and customized screening reminders.

Informatics also helps design IT systems that work better for underserved groups. By showing where care falls short, data spotlights what needs fixing. This information helps build tools that make healthcare more fair and equal. The systems can be set up to meet the needs of the real people using them.

So health information technology, along with data, provides a foundation to improve care. It helps ensure everyone, including disadvantaged groups, can access good healthcare and get better results. The data lights the way, and the technology follows to provide care that works for all. 

Reducing Costs:

The United States spends over 17-19% of its GDP on healthcare, nearly double the average of other developed nations. This high spending does not necessarily translate into better health outcomes. As a result, reducing healthcare costs has become a major policy priority. Health informatics can play a key role in curbing costs through data-driven decision-making and care optimization.

Electronic health records (EHRs) and analytics tools give providers greater visibility into resource utilization, allowing them to eliminate redundant tests and procedures. Care coordination technologies facilitate communication between providers to avoid duplicate services and medical errors, a major source of waste. Analytics can also identify high-risk patients for proactive outreach, preventing costly episodes of acute care.

In addition, informatics helps shift towards outcomes-based treatment models proven effective through statistical analysis of population data. This eliminates spending on interventions that may be profitable for a hospital but do not improve patient well-being.

Other promising cost-cutting technologies include automated patient screening, which maximizes provider time, and remote patient monitoring to minimize expensive emergency room visits and hospital readmissions. Ongoing informatics research continues seeking new ways information technology can drive efficiency gains in healthcare. However, thoughtfulness is required in implementation to avoid unintended consequences like physician burnout.


The far-reaching applications of health informatics reveal why this emerging field matters so much. By deriving insights from data, health informatics can profoundly improve medical care, public health practices, and health outcomes for all communities. For those passionate about driving progress, a career in this dynamic discipline offers an opportunity to innovate solutions that save lives every day. The future of population health relies on health informatics capabilities we are only beginning to tap into.
