Previous research has examined evidence-based hospital to SNF transitional care (TC) interventions and reported reductions in readmissions and overall cost savings (e.g. INTERACT, Ouslander, et al., 2011). However, while small scale clinical trials of TC interventions have provided some support for their efficacy (Toles, et al., 2016), little is known about general trends in SNF TC practices and how they relate to 30-day hospital readmissions. The current study fills this gap by measuring the TC practices of Ohio SNFs using data collected through two waves of a state wide survey of SNFs (over 95% response rates) and 30-day hospital readmissions, utilizing data from the nursing home Minimum Data Set (MDS 3.0). Utilizing a technique developed in the econometric literature known as instrumental variables, it is possible to statistically control for potential non-measured confounding variables that result in endogeneity. After controlling for facility, county, and individual factors, those individuals who move to a SNF with the INTERACT program in place (OR = 1.118, p < .01) or a mature TC program (OR = 1.196, p < .05) have more 30-day rehospitalizations compared to those individuals who move to a SNF with no TC program. When a differential distance IV (DDIV) is included the effects are reversed and no longer significant (OR = .405, p > .01 and OR = .785, p > .01 respectively). These results suggest that when using IV analyses, evidence-based and mature TC programs are associated with lower readmissions, though the effects are not statistically significant.
