Why doesn’t the data on CASPER Reports match scores on Home Health Compare?

We are frequently asked “Why is the data on my Casper reports different than what Health Compare?”

Home Health Compare and the Casper OBQI reports are different presentations of the same data
because they serve different purposes. Risk adjustment is used in both.

With Home Health Compare, the agency rates are risk-adjusted so comparisons can be made across
agencies that may have differences in case mix (patient acuity).  The National rate is the actual national
rate (number of episodes that achieved an outcome divided by the total number of eligible episodes
nationally) but your agency rate has been adjusted.  That means, as you compare yourself to other
agencies or as customers look at the Home Health Compare data to select an agency, the agency
specific outcome scores have been adjusted to equalize differences in patient acuity.  The national rate
will appear the same for everyone.

With the Casper OBQI Reports, the Current rate is your actual agency rate (number of episodes that
achieved an outcome divided by the total number of eligible episodes for your agency).  The prior rate
and national reference rate are risk adjusted so that differences in case mix within the same agency
over time and differences in case mix between the agency and the national case mix are accounted for.
If you looked at your April Casper report and looked at the Casper report for another agency, the national
rate would be slightly different because the national rate has been risk adjusted for each agencies
specific case-mix and patient acuity.

So you see, it’s the same data, the difference is just where the risk adjustment is applied.
