EXAM QUESTIONS AND ANSWERS:
Acute care and skilled nursing facility claim data on Medicare
patients. --- correct answer ---Medicare Provider Analysis and
Review (MEDPAR)
Database queried as part of physician credentialing process when
applying for medical staff privileges and every two years
afterward. It contains data on medical malpractice, adverse
,licensure actions, suspensions, and professional review actions. ---
correct answer ---National Practitioner Data Bank (NPDB)
Holds data on incidence and prevalence of diseases; survival
statistics; high-risk populations; and tracks trends over time. Data
is gathered from medical records, surveys, and interviews. National
Center for Health Statistics (NCHS) is responsible for these
databases. --- correct answer ---Public Health databases
Operates through the Center for Disease Control (CDC); includes
vital statistics data such as birth, death, marriages, divorces, and
fetal deaths. --- correct answer ---National Center for Health
Statistics (NCHS)
Answer key questions of interest to healthcare policy makers,
public health professionals, and researchers. Topics include quality
care, resources, safety, and disparities. --- correct answer ---
National Healthcare Survey
This is the most common of all the different types of databases.
Data in a relational database is stored in various data tables. Each
table has a key field that is used to connect it to other tables. Hence
all the tables are related to each other through several key fields.
Relational databases have advantages because the data is entered
one time, which improves the consistency and quality of data.
Searching can be done across data tables, making it easier to
,connect information. The relational database allows the data
administrator to control access to certain tables in order to provide
security for the data in the database. --- correct answer ---
Relational Databases
A flat file database is a database designed around a single table. The
flat file design puts all database information in one table, or list,
with fields to represent all parameters. A flat file may contain many
fields, often with duplicate data that are prone to data corruption.
If you decide to merge data between two flat files, you need to copy
and paste relevant information from one file to the other. There is
no automation between flat files. This opens the possibility of data
error when moving data among files. --- correct answer ---Flat File
Database
This type of database structures data similar to the layout of an
organizational chart. It is good for data storage but not versatile.
There is a one-to-many relationship of data. In a hierarchical data
model, access to data starts at the top of the hierarchy and moves
downward. --- correct answer ---Hierarchical Database Model
Object-oriented databases handle text, images, audio, video, and
other objects. In this model, images and other nontext items are
stored as objects with hierarchy and a navigational programming
style. --- correct answer ---Object-Oriented Database
, You may see this term. It refers to removing all identifying patient
information. No information can be connected back to a specific
patient. It may be used in research to protect participants and
human subjects. --- correct answer ---De-Identified Database
Data is connected through pointers, and unlike the hierarchical
model that has one "parent" to one "child," a "child" can have
multiple "parents." Multiple records can be linked to the same
owner. This model is more difficult to implement and maintain but
more flexible than the hierarchical model. It allows many-to-many
relationships. --- correct answer ---Network Database Model
This is a hybrid between hierarchical and relational, capturing the
benefits of both so that large amounts of data can be processed
quickly. You have the ability to process various data attributes at a
time, including within various hierarchies and levels. If you need
large amounts of data in a short time, this database would be useful
to you. --- correct answer ---Multidimensional Database
This is a database management system that has the capability to
roll back or undo a database transaction or operation if it is not
completed appropriately. Although this was a unique capability
several decades ago, today, the majority of relational database
systems support transactional database operations. --- correct
answer ---Transactional Database
