Medical Records
Medical records are used to track events and transactions between patients and health care providers. They offer information on diagnoses, procedures, lab tests, and other services. Medical records help us measure and analyze trends in health care use, patient characteristics, and quality of care.
Electronic health records (EHR) were first introduced in the 1960s, but only became popular recently, in part due to the American Recovery and Reinvestment Act and the Affordable Care Act. EHRs can make it easier for providers to enter information about patients. The data from EHRs can then be used for research, like comparing how effective providers are, and seeing how patients respond to treatment. In the U.S., patient privacy is still protected even with the use of EHRs by the Health Insurance Portability and Accountability Act (HIPAA), enforced by the Office for Civil Rights (OCR) of the HHS.
Medical records are usually accurate and detailed because they come from health care providers. The data are automatically collected, including information that patients might not think to add or feel comfortable sharing through other data sources like surveys. But, because the information is written down in a specific context, it can be misinterpreted if taken out of context. And of course, medical records are (by definition) only available for people who are able to get medical care.
This chart shows statistics based on information from patient medical records.
