In terms of filing systems for medical records, which system utilizes a numerical order?

The terminal digit system for filing medical records is based on a numerical order that promotes efficient organization and retrieval. This method typically segments a patient’s medical record number into three separate digits—each representing a different component of the number. The records are then organized starting from the last set of digits, proceeding to the preceding sets.

This approach aids in managing large volumes of records, as it minimizes the likelihood of overcrowding in a single numeric range, allowing for easier identification and maintenance of records over time. It also supports a method of filing that can accommodate new records without disrupting the entire sequence, leading to a more efficient filing and retrieval process compared to systems based on alphabetical, geographic, or date-based criteria. Each of those alternatives presents challenges in scalability and accessibility when compared to the benefits of the terminal digit system.
