Read the first 7 CDI Metrics and Statistics flashcards as text

  1. A hospital notices its observed-to-expected (O/E) mortality ratio is greater than 1.0. What does this indicate?

    Answer: Higher mortality than predicted by the risk model

    An O/E mortality ratio above 1.0 means actual deaths exceed what the risk model predicted, potentially indicating documentation gaps or quality issues.

  2. Which of the following CDI metrics is MOST directly tied to MS-DRG reimbursement optimization?

    Answer: Relative weight per discharge

    Relative weight per discharge directly reflects the resource intensity assigned by MS-DRGs and is the primary driver of Medicare reimbursement.

  3. A CDI team is benchmarking its physician query response rate. The industry benchmark is typically considered to be:

    Answer: Above 70%

    A physician query response rate above 70% is commonly cited as a performance benchmark, though best-in-class programs aim for 90%+.

  4. Which metric measures the average number of diagnoses documented per inpatient discharge?

    Answer: Code density

    Code density (or diagnosis density) tracks the average number of coded diagnoses per discharge, often used to compare documentation thoroughness.

  5. A CDI program reports a 'missed opportunity rate.' What does this metric typically represent?

    Answer: Cases where no query was sent despite documentation gaps

    Missed opportunity rate identifies cases where a CDI review was performed but no query was issued despite identifiable documentation gaps.

  6. When evaluating CDI productivity, which formula is used to calculate reviews per day?

    Answer: Total reviews ÷ total working days

    Reviews per day = total records reviewed ÷ total working days, a standard CDI workload productivity metric.

  7. A CDI program's financial impact report shows $1.2M in 'upward DRG shifts.' This figure is BEST described as:

    Answer: The estimated reimbursement increase from cases where queries led to a higher-weighted DRG

    Upward DRG shift value estimates the additional reimbursement attributable to documentation improvements that moved cases to higher-paying DRGs.
