An instrumental variables approach to post-acute care nursing home quality: Is there a dime's worth of evidence that continuing care retirement communities provide higher quality?

For the affluent elderly, continuing care retirement communities (CCRCs) have become a popular option for long term care and other health care needs related to aging. While CCRCs have experienced significant growth over the last few decades, very little is known about the quality of care CCRCs provide. This paper is the first to rigorously study CCRCs on a national scale and the only study that focuses on nursing home quality. Using a national sample from 2005, we determine if the quality of post-acute care provided by CCRC nursing homes is superior to traditional nursing homes. To mimic randomization of patients, instrumental variables analysis is used with relative distance as an exclusion restriction to handle the endogeneity of the type of facility where care is provided. After adjusting for endogeniety, we find that CCRC nursing homes provide post-acute care quality that is similar or lower to traditional nursing homes, depending on the quality measure.
