Prepare for the Certified Specialist in Trauma Registries (CSTR) examination with this focused study resource covering American College of Surgeons (ACS) trauma registry standards, patient inclusion criteria, data abstraction methods, staffing recommendations, data reporting, visualization techniques, and trauma performance improvement. This exam-focused material features questions and corresponding answers designed to help trauma registry students and professionals review important concepts in registry operations, data management, reporting, and quality improvement. Topics covered include: - ACS trauma patient definition and inclusion criteria, including injury-code ranges, exclusions, and qualifying events such as hospital admission, interfacility transfer by emergency medical services, and death resulting from traumatic injury. - Three types of data abstraction: concurrent abstraction during hospitalization, retrospective abstraction after discharge, and hybrid abstraction combining both approaches. - Trauma registry staffing recommendations, including the ACS reference of approximately one full-time equivalent dedicated to manual data entry for 750–1,000 patients annually. - Data retrieval and reporting requirements: selecting the correct data fields, defining time frames, applying filters, choosing grouping categories, and determining display formats. - Data presentation formats, including paper reports, websites, dashboards, spreadsheets, and presentation slides. - Tables and graphical displays, with explanations of bar graphs, pie charts, line graphs, control charts, dashboards, scatter plots, Pareto charts, radar charts, and tree or fishbone diagrams. - Volume and trend interpretation, including comparing patient totals across periods and recognizing upward or downward data patterns. - Process Improvement Patient Safety (PIPS): recognition, assessment, correction, data collection, collation, analysis, modification, and instruction. - American College of Surgeons history and its role in improving surgical patient care through standards for education and practice. - National Trauma Data Bank (NTDB): its purpose as a voluntary national repository of trauma patient information. This resource supports revision of trauma registry terminology, patient inclusion rules, abstraction workflows, staffing principles, data visualization, and quality improvement processes. Use the questions to test your recall, reinforce key definitions, and prepare for certification-related assessments.

American College of Surgeon: Resources for Optimal Care of the Injured Patient


Definition of a "Trauma Patient" can be found here:

,Any patient that has an injury in the code range between 800 and 959.9, but not one
of the exclusion codes, for late effects of injury (905-909.9), superficial injuries,
including blisters, contusions, abrasions, insect bites (910-924.9), and foreign bodies
(930-939.9). and meets one of the three event criteria: Hospital admission; Patient
transfer via emergency medical services transport from one hospital to
another hospital; or, Death resulting from the traumatic injury.


ACS inclusion criteria



Three Types of Data Abstraction


Concurrent, Retrospective & Hybrid




Concurrent Abstraction


Daily abstraction while the patient is in house


Retrospective Abstraction


Abstraction after patient discharge.


Hybrid Abstraction


Data entry is begun during the patient encounter but the record is closed after patient
discharge.

, The American College of Surgeons registry staffing recommendation for manual data
entry:


1 full-time equivalent employee dedicated to the registry to process the
data for approximately 750 to 1,000 patients annually


In order to run data for reporting the registrar
needs to know several basic details:


What information is needed to identify the correct data fields, the time frame that is
of interest, any related filters, and what format for display grouping, such as year,
month, ISS range, age range, etc.


Format


Presentation Concept of the way that the viewer wishes to view the result of the data
compiled. The format identifies how the data is to be displayed such as paper, website,
dashboard, PowerPoint presentation, etc.


Tables


Show the actual data elements arranged in rows and columns.


Graphics


A picture showing the result of data calculations. Graphic displays of information
generally work better than tables for faster interpretation of changes, trends, and
outliers.
