VERIFIED ANSWERS ALL THE BEST
Which codes in the inclusion range do not meet criteria?
Late effect codes, which are represented using the same range of injury diagnosis
codes but with the 7th digit modifier code of D through S, are also excluded.
How was a uniform data set for inclusion criteria determined?
The uniform data set for inclusion criteria in the National Trauma Data Bank
(NTDB) was established through the development of the National Trauma Data
Standard (NTDS). The NTDS, spearheaded by the American College of Surgeons
(ACS) Committee on Trauma, defines a standard set of trauma registry variables
and their definitions. This standard ensures consistent data collection across all
hospitals participating in the NTDB, regardless of their designation status. The
inclusion criteria are based on International Statistical Classification of Diseases,
Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes and certain
admission characteristics.
What is considered compliance with the National Trauma Data Standard (NTDS)
data collection requirement?
Accurate data collection, validation, and submission of all required data elements
to the National Trauma Data Bank (NTDB). This includes participation in
benchmarking programs like the Trauma Quality Improvement Program (TQIP).
Compliance also requires comprehensive data validation efforts and review of
applicable TQP reports.
What is the definition of National Trauma Data Standard (NTDS) Patient Inclusion
Criteria?
, 2
The National Trauma Data Standard (NTDS) inclusion criteria for a trauma registry
are designed to ensure consistent data collection across states, focusing on
patients with qualifying trauma diagnoses who are admitted, transferred, or die,
or for whom the trauma team is activated.
What is the ICD 10 diagnostic code range for injury inclusion criteria?
• S00-S99 with 7th character modifiers of A, B, or C ONLY. (Injuries to specific body
parts-initial encounter)
• T07 (unspecified multiple injuries)
• T14 (injury of unspecified body region)
• T79.A1-T79.A9 with 7th character modifier of A ONLY (Traumatic Compartment
Syndrome-initial encounter)
What is the ICD 10 diagnostic code range injury exclusion criteria?
• S00 (Superficial injuries of the head)
• S10 (Superficial injuries of the neck)
• S20 (Superficial injuries of the thorax)
• S30 (Superficial injuries of the abdomen, pelvis, lower back and external
genitals)
• S40 (Superficial injuries of shoulder and upper arm)
• S50 (Superficial injuries of elbow and forearm)
• S60 (Superficial injuries of wrist, hand and fingers)
• S70 (Superficial injuries of hip and thigh)
• S80 (Superficial injuries of knee and lower leg)
, 3
• S90 (Superficial injuries of ankle, foot and toes
Where can the definition of a trauma patient be found?
The definition of a trauma patient is primarily found in the American College of
Surgeons' (ACS) "Resources for Optimal Care of the Injured Patient", often called
the "Gray book".
What are the National Trauma Data Bank (NTDB) common null values? When
would these apply to the data during abstraction?
In the context of the National Trauma Data Standard (NTDS), common null values
include "Not Applicable" (N/A) and "Not Known/Not Recorded." These are used to
indicate when data is missing, irrelevant, or not documented during data
abstraction from patient records.
A local or state registry may collect both a "patient's home city" and "patient's
home ZIP code," but the National Trauma Data Standard (NTDS) requires one or
the other. Is an example of what?
This is an example of how a local registry's more granular data collection may
need to be mapped or collapsed to align with the national standard for data
submission.
Variation in data sets can be ensured that the appropriate variable is submitted to
National Trauma Data Bank (NTDB) through use of?
A mapping program or abstraction based on the National Trauma Data Standard
(NTDS) Data Dictionary should be used.
The NTDS Data Dictionary provides the exact standard for submission of trauma
registry data to the NTDB. This standard may be accomplished through abstraction
precisely in which ways?
This can be achieved either through manual abstraction, where registrars extract
specific data from patient records and map it to the NTDS Data Dictionary, or
through vendor-supplied mappings, which automate the process.
, 4
What is a benefit to having a combination of NTDS standard and vendor supplied
mappings?
It allows local and state trauma registries to maintain their individualized data
collection practices while ensuring compatibility with the national NTDS standard.
What are the dates of service for charts to be included in the NTDB and State data
submission? How often are they submitted?
Dates of service are based on the patient's date of injury or admission. The date of
service for charts is generally within 14 days of the patient's initial hospital
encounter or trauma, and submissions to both NTDB and state registries are
usually done on a quarterly basis.
What is a trauma registry? Define and explain the purpose.
A trauma registry is a data collection system that gathers information about
patients who have experienced traumatic injuries. It's used to analyze and report
on injury events, demographics, pre-hospital care, diagnosis, treatment, and
outcomes. The purpose of a trauma registry is to improve the quality of trauma
care, conduct research, and support injury prevention efforts.
Is the Trauma Registry a repository of data on incident, DX, TX?
Yes, a Trauma Registry is a repository of data that includes information about
trauma incidents, diagnoses (DX), and treatments (TX). It's a database used to
collect, store, and retrieve data related to individuals who meet specific criteria
for traumatic injuries, including demographic information, injury details, care
provided, and outcomes.
What are the types of data abstraction?
Concurrent abstraction and retrospective abstraction.
What are some examples of resources for abstracting data elements?
