Geographic variation of statin use among US nursing home residents with life-limiting illness.
The authors described regional variation in statin use among residents with life-limiting illness. Statin usage was determined by examination of Medicare Part D claims. Findings suggested extensive geographic variation in US statin prescribing across hospital referral regions, especially for those aged 76 years or older. This variation may reflect clinical uncertainty given the largely absent guidelines for statin use in nursing home residents.

Trends in serious mental illness in US assisted living compared to nursing homes and the community: 2007-2017.
This study examined trends in the prevalence of serious mental illness (SMI) in assisted living (AL) communities in the United States over time and in relationship to characteristics such as dual eligibility and health conditions. Using Medicare data, findings showed that the prevalence of SMI in AL increased by 54% from 2007 to 2017. Residents with SMI were more likely to be dually eligible for Medicare and Medicaid than residents without SMI. Approximately 10% of AL communities had over half of the sample's AL residents with SMI.

Understanding variation in postacute care: developing rehabilitation service areas through geographic mapping.
This study’s goal was to demonstrate a method for developing rehabilitation service areas for post-acute care. A secondary analysis of 2013-2014 Medicare records for older patients in Texas (n = 469,172) was conducted. The analysis included admission records for inpatient rehabilitation facilities, skilled nursing facilities, and long-term care hospitals. The authors used Ward’s algorithm to cluster patient ZIP code tabulation areas based on which facilities patients were admitted to for rehabilitation. They set the number of rehabilitation clusters to 22 to allow for comparison to the 22 hospital referral regions. Interclass Correlation Coefficient (ICC) and variance in the number of rehabilitation beds across areas were the methods used to evaluate rehabilitation service areas. The service areas had a higher ICC and variance in beds than the hospital referral regions.

Improvement in activities of daily living during a nursing home stay and one-year mortality among older adults with sepsis.
This study looked at the association between recovery of activities of daily living (ADLs) during a skilled nursing facility (SNF) stay and 1-year mortality after SNF discharge among Medicare beneficiaries treated in intensive care for sepsis. This retrospective cohort study identified 59,383 Medicare beneficiaries who were admitted to an SNF within 3 days of discharge from hospitalization that included time in an ICU for sepsis from all of 2013 to October 2015. About 58% of SNF residents showed improvement in ADL function. The higher the improvement in ADL score the less the mortality risk compared to residents who did not improve.
