Patient information refers to the data collected about an individual receiving medical care. This includes personal details such as name, age, and contact information, as well as medical history, current medications, and allergies. This information helps healthcare providers make informed decisions about diagnosis and treatment. Additionally, patient information is often stored in electronic health records (EHRs), which allow for easy access and sharing among medical professionals. Protecting this information is crucial, as it is sensitive and subject to privacy regulations like the Health Insurance Portability and Accountability Act (HIPAA) in the United States.
