|---|---|---|---|---|
| Stability* | Adjusted R2** | Stability* | Adjusted R2** | |
| All nursing homes (n=9799) | r=0.87 | 0.26 | r=0.78 | 0.01 |
| Top 25% and bottom 25% nursing homes (n=4900) | r=0.72 | 0.38 | r=0.60 | 0.01 |
| Top 10% and bottom 10% nursing homes (n=1960) | r=0.49 | 0.48 | r=0.36 | 0.03 |
Pearson correlation of the QM between Q1 and Q3 of 2005.
Derived from the multivariate ordinary least squares model of short-term change of the QM as a function of short-term change of case mix. See Table 2 for definitions of case mix variables. Short-term change of QM (or case mix) is defined as the QM (or case mix) in Q3 minus the QM (or case mix) in Q1 of 2005.
Note: Top and bottom nursing homes are defined based on rankings of the short-term change of the QM (CMS or risk-adjusted QM) between Q1 and Q3 of 2005. The stabilities for all nursing homes in the CMS QM (r=0.87) and the risk-adjusted QM (r=0.78) were identical to the ones shown in Table 2.
