Final answer:
A problem-oriented medical record organizes information into sections based on subject matter, such as grouping all laboratory results together.
Step-by-step explanation:
The type of medical record you are referring to is a problem-oriented medical record. In this system, the information is organized into separate components or sections based on the subject matter. For instance, all laboratory results would be grouped together, progress notes in another section, and so on. This helps healthcare providers quickly find the information they need based on the type of data or problem they are addressing at the moment. Other types of medical records include chronological records, SOAP (Subjective, Objective, Assessment, Plan) format, and narrative records, but the problem-oriented record is the one that specifically uses grouping by subject matter.
