The Relationship Between Reported Staffing and Expenditures in Nursing Homes.

Dramatic improvements in reported nursing home quality, including staffing ratios, have come under increased scrutiny in recent years because they are based on data self-reported by nursing homes. In contrast to other domains, the key mechanism for real improvement in the staffing ratios domain is clearer: to improve scores, nursing homes should increase staffing expenditures. We analyze the relationship between changes in expenditures and reported staffing quality pre- versus post the 5-star rating system. Our results show that the relationship between expenditures and licensed practical nurse staffing is weaker in the post-5-star period, overall, and across subgroups; furthermore, there is a weaker relationship between expenditures and registered nurse staffing among for-profit facilities with a high share of Medicaid residents in the post-5-star period. The weaker relationship between staffing expenditures and staffing scores in the post-5-star era underscores the potential for gaming of the self-reported staffing scores and the need for more reliable sources.
