CMRT Data Analytics & Reporting 3 — Questions and Answers
Question 1: A CMRT is asked to generate a report on 30-day post-discharge mortality rates. Which data source is most essential for this analysis?
- Death registry linked to discharge data (Correct answer)
- Emergency department visit logs
- Outpatient billing records
- Pharmacy dispensing records
Correct answer: Death registry linked to discharge data
Linking death registry data to inpatient discharge data is required to identify patients who died within 30 days after hospital discharge.
Question 2: In a run chart used for quality monitoring, what does a 'shift' indicate?
- Six or more consecutive data points on the same side of the median (Correct answer)
- A sudden spike in a single data point
- Two consecutive points near the control limits
- A cyclical pattern repeating every month
Correct answer: Six or more consecutive data points on the same side of the median
A shift in a run chart is defined as six or more consecutive points all above or all below the median, signaling a non-random change in the process.
Question 3: Which ICD-10-CM coding guideline directly affects the accuracy of comorbidity data reported for analytics?
- Reporting additional diagnoses that affect patient management or length of stay (Correct answer)
- Coding only the principal diagnosis for each encounter
- Omitting chronic conditions not treated during the visit
- Using unspecified codes when documentation is unclear
Correct answer: Reporting additional diagnoses that affect patient management or length of stay
Official guidelines require coding additional diagnoses that affect care or LOS, and omitting relevant comorbidities skews comorbidity analytics.
Question 4: What is the primary purpose of a health data warehouse in a hospital system?
- To integrate data from multiple source systems for enterprise-wide reporting and analysis (Correct answer)
- To store only current-encounter clinical documentation
- To replace the electronic health record for patient care
- To transmit claims to payers in real time
Correct answer: To integrate data from multiple source systems for enterprise-wide reporting and analysis
A data warehouse consolidates data from disparate systems (EHR, billing, lab, pharmacy) into a centralized repository optimized for reporting and analysis.
Question 5: A facility's coding productivity report shows a coder averaging 18 records per day while the standard is 25. Which additional metric should be reviewed before drawing conclusions?
- The coder's error rate and case complexity (Correct answer)
- The number of beds in the facility
- The payer mix for those 18 records
- The average patient age for the period
Correct answer: The coder's error rate and case complexity
Lower productivity may reflect high case complexity or excellent accuracy; reviewing error rates and complexity ensures a fair performance assessment.
Question 6: Which federal database is the primary source for national inpatient hospital discharge statistics used for benchmarking?
- Healthcare Cost and Utilization Project (HCUP) NIS (Correct answer)
- Medicare Claims Processing Manual
- SNOMED CT reference browser
- ONC Certified Health IT Product List
Correct answer: Healthcare Cost and Utilization Project (HCUP) NIS
The HCUP National Inpatient Sample (NIS) is the largest publicly available all-payer inpatient database, widely used for national benchmarking.
Question 7: When a CMRT discovers that the same patient has two Medical Record Numbers (MRNs) in the master patient index, what data quality problem does this represent?
- Duplicate records / patient identity fragmentation (Correct answer)
- Record linkage error in the billing system
- Incomplete demographic data entry
- Overlapping episode of care coding
Correct answer: Duplicate records / patient identity fragmentation
A patient with two MRNs is a duplicate record, which fragments the patient's care history and compromises the integrity of analytics using that MPI.
