Data Quality & Registry Standards Flashcards

Which type of data error occurs when an AIS code is entered for an injury that does not match the anatomical region specified?

Answer: Anatomical region mismatch

An anatomical region mismatch occurs when the coded injury does not correspond to the body region indicated by the AIS chapter.

In trauma registry data quality audits, what is the primary purpose of running a 'logic check' on ISS values?

Answer: To confirm that ISS is calculated from the three highest AIS scores in different body regions

Logic checks on ISS confirm that scores are derived from the three highest AIS severity scores from three distinct body regions as per the ISS formula.

What is the recommended approach when a trauma registry receives incomplete pre-hospital data that affects AIS coding?

Answer: Code only what is documented and flag the record for incomplete data

Best practice requires coding only documented injuries and flagging incomplete records rather than estimating missing clinical data.

Which registry standard body publishes guidelines specifically used by US trauma registries to maintain AIS data consistency?

Answer: The American College of Surgeons (ACS)

The American College of Surgeons Committee on Trauma sets the standards for verified trauma centers including registry data quality requirements.

When two coders independently assign different AIS codes to the same injury description, this is classified as a problem with:

Answer: Inter-rater reliability

Inter-rater reliability refers to the degree of agreement between different coders assigning codes to the same case.

A trauma registry shows a sudden drop in the percentage of cases with complete AIS coding for one month. What is the FIRST step in investigating this issue?

Answer: Review whether new software or a dictionary update was implemented that month

Sudden coding pattern changes often correlate with software updates, new AIS dictionary versions, or workflow changes that should be investigated first.

What does the term 'data dictionary' refer to in the context of a trauma registry using AIS?

Answer: A standardized reference defining each data element, its format, and allowable values

A data dictionary defines each registry field's name, format, valid values, and coding rules to ensure consistent data entry.
