CCDS Data Analysis 2

Question 1

A CDI manager wants to benchmark their hospital's CMI against peer institutions. Which data source is MOST appropriate?

Accepted Answer

CMS Provider of Services file or Hospital Compare data

Answer

CMS publicly reports CMI and other performance data through Hospital Compare and the Provider of Services file, enabling hospitals to benchmark themselves against peers of similar size, type, and geographic region.

Question 2

When analyzing CC/MCC capture rates by physician, a CDI analyst finds that one physician has a significantly lower capture rate than peers. What is the MOST appropriate next step?

Accepted Answer

Conduct a focused chart review to determine if documentation gaps or coding issues are the cause

Answer

Before taking any action, the CDI analyst should conduct a focused review of the physician's charts to determine whether the low capture rate reflects documentation deficiencies, a legitimately less-complex patient mix, or coding issues.

Question 3

Which statistical measure is BEST used to identify outlier cases where actual LOS far exceeds the expected LOS for the assigned DRG?

Accepted Answer

Standard deviation from the Geometric Mean Length of Stay (GMLOS)

Answer

Comparing actual LOS against the GMLOS using standard deviation identifies statistical outliers where the actual stay significantly exceeds what is typical for that DRG.

Question 4

A CDI program is evaluating its query impact. Which metric DIRECTLY measures the financial effect of CDI activities?

Accepted Answer

Revenue per query or DRG shift value

Answer

Revenue per query or DRG shift value directly quantifies the financial impact of CDI activities by calculating the dollar value of DRG weight changes resulting from documentation improvements.

Question 5

In a CDI data analysis, 'DRG pairs' are used to:

Accepted Answer

Identify diagnosis groups where documentation of a CC or MCC would change the DRG assignment

Answer

DRG pairs or triplets are groups of related DRGs where the same base diagnosis results in different DRG assignments depending on whether a CC or MCC is documented. CDI specialists use DRG pair analysis to identify high-opportunity cases.
