Domain 3-Data analytics

Question 1

Reliability

Answer 1

is frequently checked by having more than one person abstract data for the same case. The results are then compared to identify any discrepancies. This is called an interrater reliability method of checking. Several different people may be used to do the checking.

Question 2

histogram

Answer 2

is used to display a frequency distribution. It is different from a bar graph in that a bar graph is used to display data that fall into groups or categories (nominal or ordinal data) when the categories are noncontinuous or discrete

Question 3

p-value

Answer 3

The probability of making a Type I error based on a particular set of data.

Question 4

data silos

Answer 4

of information created fragmentation that still haunts some EHR systems. A data silo is a separate database or system within a department that does not integrate into the main organizational system nor can others outside of that specific department access it

Question 5

The average turnaround time

Answer 5

calculated by dividing the total response days attributed to the volume of routine requests that were responded to within the reporting period by the volume of routine requests responded to.

Question 6

The range

Answer 6

The range is the simplest measure of spread. It is the difference between the smallest and largest values in a frequency distribution:

Range = 𝒳max - 𝒳min

Question 7

assess the quality of data in the EHR

Answer 7

Auditing structured data can reveal a number of potential data quality issues, such as when all choices for a structured field are the same when a structured field is often empty.

Question 8

HIE governance

Answer 8

Agreeing on standards and how they are to be implemented for successful mapping between systems is an important part of governance

Question 9

X12N

Answer 9

refers to standards adopted for electronic data interchange. In order for transmission of healthcare data between a provider and payer, both parties must adhere to these standards

Question 10

MPI ongoing maintenance program

Answer 10

The goal is to maintain low creation rates for duplicates, overlaps, and overlays.

Question 11

scatter diagram

Answer 11

is a data analysis tool used to plot points of two variables suspected of being related to each other in some way

Question 12

Association rule learning

Answer 12

is a type of data mining that identifies interesting relationships between two concepts in the database. For example, it may identify that patients who are treated with drug A have a better outcome than patients who are treated with drug B

Question 13

line plot

Answer 13

For data that is presenting changes over time, the preferred presentation method is a line plot

Question 14

Performance standards

Answer 14

are often developed for the key functions of the job and set the quantity and quality for each job function.

Question 15

population health

Answer 15

The population health component in an EHR is designed to capture and report healthcare data that are used for public health purposes. It allows the healthcare provider to report infectious diseases, immunizations, cancer, and other reportable conditions to public health officials. This reporting is required at the local, state, and national levels and includes infectious diseases. A population health system also can connect with public health officials to receive alerts regarding health issues

Question 16

Productivity standards

Answer 16

should be aligned with the organization’s mission and goals of the organization

Question 17

HIE registry and directory

Answer 17

For whatever architecture an HIE organization may have, there needs to be a way to identify participants, which may include individual providers, representatives of payer organizations, and patients or consumers, as well as organizational entities and their information systems.

Question 18

A web portal

Answer 18

is a single point of personalized access (an entryway) through which to find and deliver information (content), applications, and services.

Question 19

The use of a dashboard

Answer 19

It monitors key measures.

Question 20

Optical character recognition (OCR)

Answer 20

In addition to bar codes on medical record documents, may be available to enhance the accuracy of indexing features on forms.

Question 21

A clinical data repository

Answer 21

is a centralized database that captures, sorts, and processes patient data and then sends it back to the user

Question 22

Stewardship

Answer 22

refers to taking care of something you own or have been entrusted with.

Question 23

Predictive modeling

Answer 23

the application uses statistical techniques to determine the likelihood of certain events occurring together.

Question 24

chart

Answer 24

offers the advantage of seeing the general trend of data and comparing differences in data between groups or over time.

Question 25

A database administrator

Answer 25

is an information technology specialist in database implementation and maintenance.

Question 26

Control charts

Answer 26

can be used to measure key processes over time. Using a control chart focuses attention on any variation in a process.

Question 27

A data model

Answer 27

is an important part of describing how data will be processed.

Question 28

structured query language (SQL)

Answer 28

It defines data elements and manipulates and controls data.

Question 29

ONC

Answer 29

The Office of the National Coordinator (ONC) has been driving the escalation of technology through its National Strategic Framework requirement of mandating the implementation of EHRs and currently toward the acceleration of health information exchange (HIE)

Question 30

Histograms

Answer 30

are used to present the distribution of numeric data. The numeric variable is broken down into groups based on specific ranges of values to establish the widths of each bar in a histogram. The height of each bar represents the frequency or density of each of the binned groups. The distribution can be described as normally distributed when the pattern follows a bell-shaped pattern

Question 31

The Digital Imaging and Communications in Medicine (DICOM)

Answer 31

the standard supports retrieval of information from imaging devices and equipment to diagnostic and review workstations as well as short-term and long-term storage systems

Question 32

Data dictionary

Answer 32

Define the data, show how it is displayed, and list attributes

Question 33

A data administrator

Answer 33

focuses on understanding interrelationships among data in order to prepare a logical design for a database.

Question 34

Controls for accuracy of the MPI

Answer 34

include limiting access to the index and limiting the ability to make changes to a few key personnel. The first step to maintaining an accurate index is to obtain the correct information at admission or registration. Hospitals often use MPIs to determine whether a patient has been seen in the facility before.

Question 35

Secondary analysis

Answer 35

is the analysis of the original work of others. In a secondary analysis, researchers reanalyze original data by combining data sets to answer new questions or by using more sophisticated statistical techniques. The work of others created the MEDPAR file

Question 36

Semantic interoperability

Answer 36

This process involves the use of standardized terminologies, such as SNOMED-CT, to provide clarity, consistency, and appropriate meaning in HIE

Question 37

Data governance managers

Answer 37

users of databases.

Question 38

Natural language queries

Answer 38

use common words to tell the database which data are needed.

Question 39

Clinical pathways

Answer 39

are a tool designed to coordinate multidisciplinary care planning for specific diagnoses and treatments

Question 40

Table

Answer 40

the precise numeric values are more easily discerned

Question 41

The staffing level

Answer 41

is determined by dividing the number of images by the expected productivity.
