Comparative effectiveness of long-term acute care hospital versus skilled nursing facility transfer.
This study compared the effectiveness of long-term acute care hospital (LTACH) use versus skilled nursing facility (SNF) transfer after hospitalization. Medicare claims linked to electronic health record (EHR) data from six Texas hospitals between 2009 and 2010 were used to conduct a retrospective cohort study of hospitalized patients transferred to either an LTACH or SNF and followed for one year. Out of 3505 patients, 18% were transferred to an LTACH and overall were younger, less likely to be female, and white, but sicker than transfers to an SNF. Patients transferred to an LTACH were less likely to survive (59 vs. 65%) or recover (62.5 vs 66%). Adjusting for demographic and clinical confounders found in Medicare claims and EHR data, transfer location was not significantly associated with differences in mortality but was associated with greater Medicare spending.

Comparative effectiveness of angiotensin II receptor blockers and angiotensin-converting enzyme inhibitors in older nursing home residents after myocardial infarction: a retrospective cohort study.
Evidence regarding differences in outcomes between angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) among older nursing home (NH) residents after acute myocardial infarction (AMI) is limited. The purpose of this study was to estimate the post-AMI effects of ARBs versus ACEIs on mortality, rehospitalization, and functional decline outcomes in this important population.

Cost-effectiveness of nutrition intervention in long-term care.
The researchers sought to determine the cost-effectiveness of two nutrition interventions on food, beverage, and supplement intake and body weight. They found that oral liquid nutrition supplements and snack offers were efficacious in promoting caloric intake when coupled with assistance to promote consumption and a variety of options, but neither intervention resulted in significant weight gain.

Instrumental variable applications using nursing home prescribing preferences in comparative effectiveness research.
The objective of this study was to explore the presence of unexplained between-nursing home (NH) variation in prescribing and to empirically evaluate the validity of instruments based on NH prescribing preference. High-prescribing and low-prescribing nursing homes differed by a factor of 2. There was no evidence that instrument status was associated with markers of nursing home quality of care.
