CSTR Review Questions with Verified Correct
Answers
What are the three primary types of guidelines that are considered for inclusion criteria
of a patient into the registry?
- ICD-10-CM codes for traumatic injuries
- a 14-day window from initial hospital encounter
- specific injury types
What are the American College of Surgeons (ACS) Guidelines for inclusion criteria?
Primarily based on the National Trauma Data Standard (NTDS). A patient is generally
included if they have a qualifying trauma diagnosis code and are either admitted, transferred,
or die. If the trauma team is activated, the patient qualifies for the registry regardless of
diagnosis or ED disposition. Additionally, the NTDS includes patients who sustain a
qualifying traumatic injury within 14 days of their initial hospital encounter and are
transferred to another acute care hospital.
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?
,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)
• S90 (Superficial injuries of ankle, foot and toes
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.
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.
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?
