Post-acute care use patterns among hospital service areas by older adults in the United States: a cross-sectional study.
This study examined post-stroke acute care patterns across Hospital Service Areas among a national stroke cohort of Medicare beneficiaries to determine drivers of variation in post-acute care service utilization. Data was extracted from 2013 to 2014 (174,498 total records across 3232 Hospital Service Areas). Patients’ residence ZIP codes were linked to the facility ZIP code where care was received. Patients were considered a “traveler” if they did not live in the Hospital Service Area where they received care. Only 23.5% of all patients received care in skilled nursing-only Hospital Service Areas although 73.4% of all Hospital Service Areas were skilled nursing-only. Thirty-five percent of all patients traveled to a different Hospital Service Area from their residence. Patients living in skilled nursing-only Hospital Service Areas had more than 5 times the odds of traveling compared to those living in Hospital Service Areas with skilled nursing, inpatient rehabilitation, and long-term care hospital services.

Resource utilisation among patients transferred for intracerebral haemorrhage.
Patients with intracerebral haemorrhage (ICH) are frequently transferred between hospitals for higher level of care. The investigators aimed to identify factors associated with resource utilisation among patients with ICH admitted to a single academic hospital. They used a prospectively collected registry of consecutive patients with primary ICH at an urban academic hospital between 1 January 2005 and 31 December 2015.

Changes in use of postacute care associated with accountable care organizations in hip fracture, stroke, and pneumonia hospitalized cohorts.
In this study, researchers examined changes in more and less discretionary condition-specific postacute care use associated with Medicare accountable care organization (ACO) implementation. They found that ACOs decreased spending on postacute care by decreasing use of discretionary services. In addition, ACO implementation was associated with reduced length of stay in skilled nursing facilities, while hip fracture patients used institutional postacute settings at higher rates. The authors also observed decreases in spending, readmission days, and mortality among pneumonia patients.

Stroke risk stratification in acute dizziness presentations: a prospective imaging-based study.
The researchers estimated the ability of bedside information to risk stratify stroke in acute dizziness presentations. They found that in acute dizziness presentations, the combination of ABCD(2) score, general neurologic examination, and a specialized ocular motor examination has the capacity to risk-stratify acute stroke on MRI.
