What are the three major types of paper based health records?

There are four major types of paper-based health records:

Source-oriented medical record: This type of record is organized by the source of the information, such as the physician, nurse, or laboratory. It is the most common type of paper-based health record and is typically used in small clinics and private practices.

Problem-oriented medical record: This type of record is organized by the patient's problems, such as diabetes, hypertension, or asthma. It is typically used in larger clinics and hospitals and can help to improve the coordination of care.

Chronological medical record: This type of record is organized by the date of the patient's visit. It is typically used in emergency departments and urgent care clinics.

Flow sheet medical record: This type of record is a graphic representation of the patient's vital signs, laboratory results, and other data. It is typically used in intensive care units and other critical care settings.
