Method: The authors use data from the On-line Survey Certification and Reporting system to identify free-standing NHs that first reported a D-SCU between 1996 and 2003 ( N = 1,519). Fixed-effects models estimate the effect of a new D-SCU on the prevalence of each outcome (physical restraints, feeding tubes, and psychotropic medications) while controlling for secular trends. Results: For all NHs, the use of physical restraints declined, the use of antipsychotics increased, and other measures remained relatively constant. The introduction of a D-SCU was not associated with changes in trends for any measure. Discussion: Differences in care processes between NHs with and without D-SCUs are the result of differences in their underlying approach to care, not the result of care practice diffusion from the D-SCU.<\/jats:p>","DOI":"10.1177\/0898264308324632","type":"journal-article","created":{"date-parts":[[2008,9,24]],"date-time":"2008-09-24T18:07:42Z","timestamp":1222279662000},"page":"837-854","source":"Crossref","is-referenced-by-count":23,"title":["Does
