OBQI Risk Adjustment Model Released

Homecare Insider, September 26, 2011

Homecare providers have long expected the publication of the Outcome Based Quality Improvement (OBQI) risk adjustment model, which was recently released. Developed using OASIS repository data from January 1, 2010 and September 30, 2010, the logistic regression model predicts outcome results for three utilization outcomes, 22 functional improvement outcomes, 11 functional stabilization outcomes, and 12 potentially avoidable events. Nine of these outcomes are publicly reported including one utilization outcome, seven functional improvement outcomes, and one potentially avoidable event. The observed agency outcome rate is calculated by taking the number of patients who achieved a particular outcome and dividing it by the number of patients eligible for that outcome in the episodes of care that ended in the previous 12 months.

The method used to calculate the national reference rate for a given outcome for each agency is:

  • A predicted outcome probability is calculated for each patient in the agency, based on the patient’s health status and other attributes at admission to home health care, using a statistical model specific to that outcome.
  • Predicted outcome probabilities are averaged across all of the agency’s patients eligible for that particular outcome to arrive at an agency-specific predicted outcome rate.
  • Predicted outcome probabilities are averaged across all home health patients in the nation eligible for that particular outcome to arrive at a national predicted outcome rate.
The National Reference Rate for a specific agency is calculated as:
  • National Observed Rate plus (Agency-Specific Predicted Rate minus National Predicted Rate).
This method of calculating a risk-adjusted reference rate for home health agencies considers variations between agencies in patient case mix, and provides a means for all agencies to measure their outcomes against a risk-adjusted standard that reflects current national outcome performance.
