CMRT Data Analytics & Reporting 5 — Questions and Answers
Question 1: A CMRT must de-identify a dataset for release under HIPAA's Safe Harbor method. Which of the following identifiers must be removed?
- All geographic data smaller than a state, dates more specific than year, and 18 other specified identifiers (Correct answer)
- Only the patient name and Social Security Number
- Only dates of service and provider names
- Name, address, and insurance ID only
Correct answer: All geographic data smaller than a state, dates more specific than year, and 18 other specified identifiers
Safe Harbor de-identification requires removal of all 18 HIPAA-specified identifiers including geographic subdivisions smaller than a state and dates more specific than year.
Question 2: Which dashboard visualization type is most appropriate for tracking a KPI against a target over time?
- Line chart with a target reference line (Correct answer)
- Stacked bar chart by department
- Heat map by patient population
- Box plot of daily admissions
Correct answer: Line chart with a target reference line
A line chart with a horizontal target reference line clearly shows performance trends over time relative to the established goal.
Question 3: When evaluating the reliability of a clinical registry's data, a CMRT checks whether two abstractors reviewing the same records assign the same values. This is called:
- Inter-rater reliability (Correct answer)
- Criterion validity
- Internal consistency
- Predictive validity
Correct answer: Inter-rater reliability
Inter-rater reliability measures the degree of agreement between two or more independent abstractors coding the same data, reflecting consistency.
Question 4: A facility wants to compare its surgical complication rates with peer hospitals while accounting for differences in patient severity. Which statistical technique is most appropriate?
- Risk adjustment / case-mix adjustment (Correct answer)
- Simple percentage comparison
- Frequency distribution analysis
- Chi-square test on raw complication counts
Correct answer: Risk adjustment / case-mix adjustment
Risk adjustment controls for differences in patient population severity and comorbidities so that outcome comparisons across facilities are fair and valid.
Question 5: In health informatics, what does 'interoperability' mean in the context of data reporting?
- The ability of different systems to exchange and use shared health data seamlessly (Correct answer)
- The security encryption of transmitted health records
- The process of converting paper records to digital format
- The standardization of billing codes across payers
Correct answer: The ability of different systems to exchange and use shared health data seamlessly
Interoperability is the capacity of different health IT systems to communicate, exchange data, and use that information without special effort from the user.
Question 6: Which AHIMA data quality characteristic ensures that a data value means the same thing regardless of where or when it is collected across the organization?
- Consistency (Correct answer)
- Precision
- Timeliness
- Accessibility
Correct answer: Consistency
Consistency means the same data element is defined and collected uniformly across departments, time periods, and systems within the organization.
Question 7: A CMRT is asked to identify patients who meet criteria for a quality measure using structured EHR data. Which type of query tool is most commonly used for this?
- Clinical Quality Language (CQL) logic within a measure engine (Correct answer)
- Free-text keyword search of physician notes
- Manual chart review with paper abstraction forms
- ICD-10 encoder look-up tool
Correct answer: Clinical Quality Language (CQL) logic within a measure engine
CQL is a standardized, human-readable query language used to express electronic clinical quality measure (eCQM) logic against structured EHR data.
