Data Management Flashcards
refers to the use of computers to store, access, and secure patient information.
Data Management
This is the information that is not required on a daily basis by the typical system user, but is used by management to make decisions
Data Warehouse
n effective data warehouse as has the following characteristics
Subject - oriented
Time - variant
Non- volatile
Integrated
This refers to the fact that all events or objects that are the same are linked in a traceable manner.
Subject - oriented
This is the ability to look at how information changes as a function of time.
Time - Variant
This means that once information is recorded, it can never be deleted or manipulated in a manner that could cause its loss.
Non-volatile
This refers to the fact that information from all areas of the enterprise is placed into the same database for the sake of analysis.
Integrated
There are three major parts of a data warehouse:
Infrastructure
Data
Process
(sometimes referred to as the technology perspective) refers to the hardware and software used in the system.
The infrastructure
are diagram representations of the structures that send and store information and how they relate to one another.
Data
defined by how information gets from one place to another or how it is dealt with.
Process
Most data warehouses use ______________ of normalization.
Codd Rules
breaks data down into a table in order to show the relationships between the various parts.
Codd Rules
breaks data down into numerical facts and reference information.
Dimensional
easy to use and operate quickly
Dimensionally based databases
saves information in the “third normal form” and groups the information into tables according to their subjects.
Normalized
These databases can be slow and difficult to use.
Normalized based databases
There are four types of data warehouses that have evolved
Offline operation databases
Offline data warehouse
Real-time data warehouse
Integrated data warehouse
are simply copies of the operation system saved to a separate location or partition on the server.
Offline operation databases
creates a regular copy of the operational system used in a report-orientated system.
Offline data warehouse
Similar to offline data warehouses except that they are constantly updated.
Real-time data warehouse
updated with information, processes it, and returns the results to the central system for use in daily activities.
integrated data warehouse
There are basically four types of health care–related data
Medical/clinical data
Knowledge- based data
Comparison data
Aggregate data
This information is patient-specific and includes information regarding the patient, diagnosis, treatment, laboratory findings, consultations, care plans, physician orders, informed consent, and advance directives.
Medical/clinical data
This information includes methods to ensure that staff is provided training, support, research, library services or other access to information, and good practice guidelines.
Knowledge- based data
These data may relate to internal comparisons or external comparisons to benchmarks or best-practice guidelines.
Comparison data
These data include pharmacy transactions, required reports, demographic information, financial information, hazard and safety practices, and any data not included in the clinical record.
Aggregate Data
used for analysis
Qualitative and Quantitative data
Data are described verbally or graphically, and the results are subjective, depending on observers to provide information.
Qualitative Data
Data are described in terms of numbers within a statistical format.
Quantitative data
This information gathering is done after the design of data collection is outlined, usually in later stages.
Quantitative data
Original data are collected for a particular purpose.
Primary data
Data were originally collected for another purpose.
Secondary data
There are several common methods that preserve data integrity
Staff education
system checks
data verification
minimization of fraudulent information
assigned to data that an organization collects.
Attributes
two important pieces of information that must be assigned to attributes
Name and Domain
