Association Between Thrombolytic Door-to-Needle Times and Ischemic Stroke Outcomes
This cohort study estimates associations between intravenous tissue plasminogen activator (tPA) door-to-needle times of less than 4.5 hours for acute ischemic stroke and 1-year mortality or readmission among Medicare beneficiaries aged 65 years or older.

Trends in Carotid Revascularization Procedures
To the Editor In a study of Medicare beneficiaries during 1999-2014, 30-day ischemic stroke or death rates after carotid endarterectomy improved (from 4.4% in 1999-2000 to 3.1% in 2013-2014), as did all-cause mortality (from 1.6% to 1.1%). In contrast, 30-day ischemic stroke or death rates after carotid artery stenting did not differ between the beginning and the end of the study period (7.0% in 1999-2000 and 7.0% in 2013-2014) and neither did all-cause mortality (4.7% in 1999-2000 and 4.8% in 2013-2014). Importantly, 30-day ischemic stroke or death rates after carotid artery stenting were higher than those recommended by ...

Trends in Carotid Revascularization Procedures —Reply
In Reply Dr Hussain and colleagues point out interesting comparisons in carotid revascularization trends in Ontario, Canada, and in the US Medicare population, including similar 30-day stroke or death outcomes after carotid endarterectomy and stenting. We agree that differing reimbursement policies in the United States and Canada may account for differing patterns of carotid stenting after 2006. A noted difference is the lower receipt of procedures among symptomatic patients in the United States vs Ontario. However, such variation is expected because the approach to asymptomatic treatment has been shown to vary among Western countries.

Clinical Outcomes at 1 Year Following Transcatheter Aortic Valve Replacement
ImportanceIntroducing new medical devices into routine practice raises concerns because patients and outcomes may differ from those in randomized trials.ObjectiveTo update the previous report of 30-day outcomes and present 1-year outcomes following transcatheter aortic valve replacement (TAVR) in the United States.Design, Setting, and ParticipantsData from the Society of Thoracic Surgeons/American College of Cardiology (STS/ACC) Transcatheter Valve Therapies Registry were linked with patient-specific Centers for Medicare & Medicaid Services (CMS) administrative claims data. At 299 US hospitals, 12 182 patients linked wit...

Cause-Specific Risk of Hospital Admission Related to Extreme Heat in Older Adults
ImportanceHeat exposure is known to have a complex set of physiological effects on multiple organ systems, but current understanding of the health effects is mostly based on studies investigating a small number of prespecified health outcomes such as cardiovascular and respiratory diseases.ObjectivesTo identify possible causes of hospital admissions during extreme heat events and to estimate their risks using historical data.Design, Setting, and PopulationMatched analysis of time series data describing daily hospital admissions of Medicare enrollees (23.7 million fee-for-service beneficiaries [aged ≥65 years] per year; 8...

Association of the 2011 ACGME Resident Duty Hour Reforms With Mortality and Readmissions Among Hospitalized Medicare Patients
Conclusions and RelevanceAmong Medicare beneficiaries, there were no significant differences in the change in 30-day mortality rates or 30-day all-cause readmission rates for those hospitalized in more intensive relative to less intensive teaching hospitals in the year after implementation of the 2011 ACGME duty hour reforms compared with those hospitalized in the 2 years before implementation.
