The field of health informatics emerged as a distinct discipline in the 1950s and became its own field of study in the 1960s, according to the book The History of Medical Informatics in the United States. In the late 1960s, the American Society for Testing and Materials began developing standards for electronic health record systems, electronic messaging, and data content and security. As technology evolved, the need to organize and analyze health information increased as well — and now, decades later, health informatics is both complex and growing.

What Is Health Informatics?

“Health informatics is both the processes and the tools used to record, store, and analyze health care information,” says Zeynep Behjet, MD, MSHI, program chair for the master program of Health Informatics in Purdue Global’s School of Health Sciences. “Health informatics is where health care, computer science, and information management meet.”

Health informatics professionals analyze information for health care companies, hospitals, and the government. The purposes of doing so are varied; a health informatics worker might analyze data to:

  • Report it to the government (such as the number of hospital admissions)
  • Conduct research (for example, examining large datasets to conduct population-based research)
  • Predict trends and outcomes (for example, the National Center for Biotechnology Information reports that health informatics specialists from the Johns Hopkins School of Medicine were able to analyze Google Flu Trends data to predict spikes in flu-related emergency room visits at least a week earlier than the Centers for Disease Control)
  • Manage health care and health care resources (health information systems were considered critical in helping manage patients, resources, and populations during the COVID-19 crisis, according to one study)

Why Is Health Informatics Important?

Health informatics plays an important role in improving patient outcomes. The ultimate goal of health informatics is to connect health care data to those who use it to advance medicine.

To that end, health informatics is used to:

  • Foster collaboration among health care providers
  • Establish policies and procedures that improve operations and the quality of patient care
  • Build and improve databases, and develop information management and data security policies
  • Contribute to the body of shared knowledge that enables a society to report on itself and improve public health

What Can You Do With a Master's Degree in Health Informatics?

According to Behjet, two types of people usually enter health care informatics:

  • Experienced health care professionals who are looking to advance their careers, or
  • IT specialists looking to transition into the health care industry

“The precise job titles one can hold with a master’s degree in health informatics are varied because it depends on the background of the student,” Behjet says. “This is also something that's not settled yet because it is such a new field. Health care organizations are titling the jobs according to the responsibilities they want fulfilled.”

A sampling of job titles for those who work in health informatics includes:

  • Medical records and health information technician
  • Compliance officer
  • Application analyst
  • Clinical analyst
  • Data analytics/data mining engineer
  • Health informatics advocate
  • Public health information officer

It’s possible to become certified in health informatics by the American Health Information Management Association.
