Health care is based on research. Medications are developed through research, under rigorous review and with people agreeing to participate in research studies. But, in the past, research did not always include people from all racial and ethnic backgrounds. Also, historically, people from certain racial and ethnic backgrounds have been reluctant to participate in research. Therefore, research has been done on limited patient populations.

“For example, a lot of research on cholesterol medication has been done on middle-aged white men,” says Dr. Massart. “We wouldn’t know if that medication would have the same effect on, say, African American women or Latino men. So, we can’t always base health care practices on the research that has been done.”

Precision medicine involves getting as much data as possible, from as diverse a patient population as possible. It allows doctors to put research in context with a patient’s personal information and create a treatment specific to that person. Health care providers like Dr. Massart consider this a step forward in the practice of medicine.

Precision medicine also has the potential to positively affect the use of medications. Research is revealing more about how people’s genetic makeup affects their response to certain medications (the field of pharmacogenomics). With this information and all the data about personal history, doctors can know right away which medicine will work best for an individual instead of going through the sometimes-long process of trying a medication, waiting to see if it works, moving on to the next medication, waiting to see if it works and so on.

Because precision medicine involves the use of personal information, people sometimes have privacy concerns. Dr. Massart notes the Genetic Information Nondiscrimination Act (GINA) of 2008. It prohibits the use of genetic information in health insurance and employment. GINA provides some protection.

People from Southwestern Pennsylvania have an opportunity to contribute to the precision medicine momentum. Former president Obama, recognizing that we needed a much broader and diverse research database, created the All of Us research program through the National Institutes of Health. PA Cares for Us is the local arm of the national program. The University of Pittsburgh was awarded a grant to recruit participants over the next five years. The goal is to recruit a truly diverse population—diverse in terms of geography, age, ethnicity, race, sexual orientation, gender identification, etc.—from Western Pennsylvania. Participants will join a research network where they will provide access to their electronic health records, personal history, and bio samples (urine and blood for genetic testing, weight, height, blood pressure, etc.). Participants will have opportunities over many years to provide data about themselves that will help researchers learn more about how individual differences in lifestyle, environment and biological make-up (such as genetic background) influence health and disease. This is expected to lead to new treatments tailored to individual patients.

Precision medicine is starting to be a part of people’s health care. Dr. Massart says, “We’re using genetic information to know patients’ risk for having certain diseases and how to treat them (like testing a patient for a BRCA gene mutation, which can indicate a higher risk for cancer, if that patient has a consistent family history of breast or ovarian cancers). We don’t have global genomic information being integrated into many health systems yet, but some are starting that process.”
