DRE Quality Assurance & Improvement 3 — Questions and Answers
Question 1: A DRE program coordinator wants to reduce variation in how evaluators measure blood pressure. The MOST effective QA intervention is:
- Purchase more expensive sphygmomanometers for all DREs
- Develop a standardized measurement protocol and train all DREs to it (Correct answer)
- Allow each DRE to use whichever method they prefer
- Eliminate blood pressure measurement from the 12-step process
Correct answer: Develop a standardized measurement protocol and train all DREs to it
Standardized protocols reduce measurement variation by ensuring all evaluators follow the same procedure under the same conditions.
Question 2: Which of the following BEST describes the purpose of the Drug Influence Report (DIR) from a QA perspective?
- It serves as the sole legal document used to prosecute DUID cases
- It creates a structured, auditable record of each evaluation for review and trend analysis (Correct answer)
- It replaces the need for toxicological confirmation in court
- It is used exclusively by the prosecuting attorney and is not reviewed internally
Correct answer: It creates a structured, auditable record of each evaluation for review and trend analysis
The DIR provides a consistent documentation format that enables supervisors to audit evaluations, identify errors, and track performance trends.
Question 3: When reviewing DRE statistics for QA purposes, a high rate of 'no drugs detected' opinions that are later contradicted by positive toxicology MOST likely indicates:
- The toxicology lab is producing false positive results
- DREs may need additional training in detecting low-dose impairment (Correct answer)
- The subjects were not actually impaired at the time of evaluation
- The 12-step protocol is fundamentally flawed and should be abandoned
Correct answer: DREs may need additional training in detecting low-dose impairment
A pattern of missed detections suggests DREs may lack the skill to recognize subtle impairment signs, pointing to a training need.
Question 4: In QA terminology, 'inter-rater reliability' in the DRE context refers to:
- The ability of a DRE to get consistent results when evaluating the same subject twice
- The degree to which different DREs reach the same conclusions given the same physical findings (Correct answer)
- The correlation between DRE opinions and jury verdicts at trial
- The consistency of toxicology lab results across different testing methods
Correct answer: The degree to which different DREs reach the same conclusions given the same physical findings
Inter-rater reliability measures whether the DRE protocol produces consistent opinions across different evaluators observing the same indicators.
Question 5: A jurisdiction's QA data shows that DRE evaluations of cannabis-only impairment have a lower toxicology confirmation rate than evaluations involving other drug categories. The BEST first step is:
- Exclude cannabis-only cases from future QA reporting
- Analyze those specific DIRs to identify which indicators were recorded and how they were interpreted (Correct answer)
- Immediately retrain all DREs on the entire drug category matrix
- Request that the state legislature lower the per se THC limit
Correct answer: Analyze those specific DIRs to identify which indicators were recorded and how they were interpreted
Root cause analysis of the specific evaluation records must precede any corrective action to ensure the intervention targets the actual gap.
Question 6: Which element of the DRE 12-step process is MOST commonly flagged during QA audits as incompletely documented?
- Breath alcohol concentration
- The DRE's opinion regarding drug category
- Pulse rate measurements taken at multiple steps (Correct answer)
- The subject's name and date of birth
Correct answer: Pulse rate measurements taken at multiple steps
Pulse rate must be recorded at steps 2, 6, and 11, and audits frequently find that one or more of these measurements is missing or not repeated.
Question 7: A state DRE coordinator uses annual QA data to prioritize continuing education topics. This practice BEST exemplifies which QA principle?
- Punitive accountability
- Data-driven program improvement (Correct answer)
- Reactive crisis management
- Passive oversight
Correct answer: Data-driven program improvement
Using performance data to guide training priorities is the hallmark of a data-driven continuous improvement approach to QA.
