One of PCORI’s goals is to improve the methods that researchers use for patient-centered outcomes research. PCORI funds methods projects like this one to better understand and advance the use of research methods that improve the strength and quality of comparative effectiveness research.
This research project is in progress. PCORI will post the research findings on this page within 90 days after the results are final.
What is the research about?
People get health care from many places, such as doctor’s offices, hospitals, and pharmacies. Each place creates and stores patient health records. These records include identifiers, or pieces of information that reveal a patient’s identity, such as name, birth date, or address. When sharing or using patient health records for research, organizations usually remove identifiers to protect patients’ privacy.
Having more complete patient records that use data from more than one source could help improve patient care, public health reporting, and medical research. Researchers need ways to link patient data from different sources while ensuring patient privacy. But linking patient records from different sources can be hard without identifiers. Also, too much health information in one record creates a privacy risk, even if there are no identifiers. People with uncommon conditions might be recognized by their health records. In this study, the research team is building and using tools to link patient records from multiple sources without identifiers.
Who can this research help?
Researchers can use the findings from this study when considering ways to link patient data from multiple sources without using identifiers.
What is the research team doing?
The research team is building software to link health data without identifiers. The software is adapting methods that are used to link identified data for this purpose. The team is also using real patient records to confirm that they are linking the correct data together.
The research team is holding focus groups to hear ideas and concerns from patients, healthcare providers, researchers, and technology and policy professionals. A patient is a member of the research team.
