OASIS-C Outcome Data Now Reported

Homecare Insider, July 25, 2011

As agencies know, there are three types of Home Health Quality Measures based on OASIS-C-process measures, outcome measures and potentially avoidable events. Home health outcome and potentially avoidable event scores, based on OASIS-C data, are now being reported publicly after a long black-out period to allow for the collection of sufficient OASIS-C data and risk model development. Process measures have been reported since October 2010.

If agencies are not already focusing on outcomes as a huge component of their quality improvement programs, they should do so now. Doing so, means that they need to have an understanding of how their outcomes are calculated, including risk adjustment prediction. Risk adjustment is defined as a method of compensating for differences in patient risk factors between two samples, or groups, of patients. It minimizes the possibility that outcome differences between comparison groups are due to factors other than the care an agency provides. It is important for agencies to know and remember that each outcome measure has its own risk model and that OASIS items are used in developing those risk models. Predicted values are calculated each time an outcome report is produced and risk adjustment models are re-done every three to five years or when new versions of OASIS are released – like the release of OASIS-C.

In order for agencies to learn about the meaning and use of their outcome and process measure reports, they should refer to the CMS manuals on Outcome Based Quality Improvement (OBQI), Outcome Based Quality Monitoring (OBQM), and Process Based Quality Improvement (PBQI). Appendix C of the OBQI Manual gives an overview of risk adjustment methodology.
