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.

Trends in isolated surgical aortic valve replacement according to hospital-based transcatheter aortic valve replacement volumes.
This research analyzed trends in isolated surgical aortic valve replacement (SAVR) procedures with the advent of the transcatheter aortic valve replacement (TAVR) procedure. Hospitalizations of adults from January 2011 through December 2014 was analyzed with data from the Medicare Provider Analysis and Review database using ICD-9 Revision-Clinical Modification procedure codes. The annual value of isolated SAVR went down as TAVR volumes increased which also decreased short- and long-term mortality over the study period.

Interfacility transfer of Medicare beneficiaries with acute type a aortic dissection and regionalization of care in the United States.
Researchers investigated the hypothesis that regionalizing care at high-volume hospitals for acute type A aortic dissections will lower mortality. Operative mortality and long-term survival were compared for Medicare beneficiaries diagnosed with an acute type A aortic dissection who were transferred versus not transferred, underwent surgery at high-volume versus low-volume hospitals, and were rerouted versus not rerouted to a high-volume hospital for treatment. The researchers found that, despite delaying surgery, a regionalization policy that transfers patients to high-volume hospitals was associated with a 7.2% absolute risk reduction in operative mortality. They recommended that policymakers evaluate the feasibility and benefits of regionalizing the surgical treatment of acute type A aortic dissection in the United States.

Trends in the use of skilled nursing facility and home health care under the Hospital Readmissions Reduction Program: an interrupted time-series analysis.
Medicare's Hospital Readmission Reduction Program penalizes hospitals with elevated 30-day readmission rates for acute myocardial infarction, heart failure, or pneumonia. The authors investigated if, in order to reduce readmissions, hospitals may have increased referrals to skilled nursing facilities and home health care. They found that hospitals might be shifting to more intensive postacute care to avoid readmissions among seniors with pneumonia. At the same time, penalized hospitals' efforts to prevent readmissions may be keeping higher proportions of their patients in the community.

A network approach to stroke systems of care.
This study provided a network analysis of stroke systems of care. Stroke patients are increasing transferred between hospitals to receive higher levels of care, but coordination and triage of these patients remains a challenge. The network analysis provides an understanding of the central hubs, the change of network structure over time, and the dissemination of innovations.

Evaluation of the experience of spoke hospitals in an academic telestroke network.
Implementation of telestroke has been associated with improved thrombolysis rates and clinical outcomes in remote or neurologically underserved spoke hospitals. Yet, the experience of spoke hospitals using telestroke has not been well described. In this study, the investigators sought to characterize spoke hospitals' perceptions of telestroke to understand perceived advantages, challenges, and barriers to use.

Use, temporal trends, and outcomes of endovascular therapy after interhospital transfer in the United States.
This study examined the use, trends and outcomes of endovascular therapy (EVT) after interhospital transfer in the United Sates. This cohort study analyzed trends from over 1.8 million patients with ischemic stroke admitted to 2143 Get With The Guidelines-Stroke participating hospitals between 2012 and 2017. There were differences in mortality for interhospital transfer patients, although those differences disappeared after adjusting for delay in EVT initiation.

Using a society database to evaluate a patient safety collaborative: the Cardiovascular Surgical Translational Study.
The authors assessed the utility of using external databases for quality improvement (QI) evaluations in the context of an innovative QI collaborative aimed to reduce three infections and improve patient safety across the cardiac surgery service line. They compared changes in each outcome between 15 intervention hospitals and 52 propensity score-matched hospitals, and found that improvement trends in several outcomes among the studied intervention hospitals were not statistically different from those in comparison hospitals. They conclude that using external databases may permit comparative effectiveness assessment by providing concurrent comparison groups, additional outcome measures, and longer follow-up.
