answers already passed 2025/2026
Master Patient Index (MPI) - correct answer ✔permanent record of every patient that has been treated
at that healthcare facility
MPI functions - correct answer ✔primary guide to locating pertinent demographic data about the
patient and his/her health record number
Enterprise Master Patient Index (EMPI) - correct answer ✔references all patients in two or more
facilities
Registration, Admission, Discharge, Transfer (R-ADT) - correct answer ✔- patient registration system
- functions as the MPI
- ability to access data by more than one indiv. at a time
Duplicate Medical Record Number - correct answer ✔assigns a patient a new medical record number
when the patient already has an existing medical record number
Overlay - correct answer ✔patient is assigned another patient's medical record number or medical
information
Overlap - correct answer ✔when more than one medical record number exists for the same patient
within an enterprise at different facilities/databases
What is entailed in a MPI Maintenance program? - correct answer ✔- ongoing process to identify &
address existing errors
- advanced person search capabilities for minimizing the creation of new errors
,- mechanism for efficiently detecting, reviewing, and resolving potential errors
- ability to reliably link different medical record numbers and other identifiers for the same person to
create an enterprise view of the person
- consideration of the types of physical merges & the interfaces & correction routines to other electronic
systems that are populated or updated by the EMPI
Health Information Exchange (HIE) - correct answer ✔used to describe both the sharing of health
information electronically among two or more entities and also an organization that provides services to
accomplish this information exchange
What is the purpose of HIE? - correct answer ✔increase the availability of health information to
authorized stakeholders in order to improve quality & safety of healthcare delivery across the
continuum
Serial Numbering System - correct answer ✔patient receives a unique numerical identifier for each
encounter or admission to a healthcare facility
Unit Numbering System - correct answer ✔- commonly used
- a patient receives a unique health record number at the time of the first encounter
- an advantage is that all information, regardless of the number of encounters, can be filed or linked
together
Serial-unit Numbering System - correct answer ✔- attempt to combine the strengths & minimize the
weakness of the serial & unit numbering systems
- previous health records are brought forward & filed under the last assigned health record number & it
created a unit record
Alphabetic Identification & Filing System - correct answer ✔patient's last name is used as the first
source of identification & his/her first name and middle initial provider further identification
, Health Record Number - correct answer ✔- special file folder that is filed either alphabetically or
numerically, depending on the size of the organization
- assigned to a patient upon admission to a facility is the number also used to file to record in numeric
filing system
Alphabetic filing system - correct answer ✔- records are arranged in alphabetic order
- easy to create & use
- often called a direct filing method b/c it does not rely on an index or an authority file & the user can
find a file by looking directly under the name of the record
Disadvantages of the alphabetic filing system: - correct answer ✔- does not ensure a unique identifier
- alphabetic files do not expand evenly
- time consuming to purge or clean out files for inactive storage
Numeric filing system - correct answer ✔records are filed by using the health record number
Indirect filing system - correct answer ✔an index or authority file needs to be consulted before the user
can identify a record associated with a specific patient
Straight numeric filing system - correct answer ✔records are arranged consecutively in ascending
numeric order
Terminal-digit filing system - correct answer ✔- most efficient
- last digit/group of last digits is the primary unit used for filing, followed by the middle unit & the last
unit of numbers
Middle-digit filing system - correct answer ✔- similiar to the terminal-digit filing system
- primary unit is the middle unit, the secondary is the first unit to the left, followed by the last digits
