a
The sample size for the POD QMs included 15,036 nursing homes and for the hospice QM 15,265 nursing homes.
b
The sample size for the POD QMs included 6892 nursing homes and for the hospice QM 6375 nursing homes.
c
Example: Of the 1504 nursing homes in 2005 in the top decile of quality, 25.6% remained in the top decile in 2006.
d
Example: In 2006 1523 nursing homes were at the top decile based on the POD QM; 349 of those (or 22.9%) were also classified into the top decile by the hospice QM.
POD, place of death; QM, quality measure.
