Comparison of Out-of-Hospital Cardiac Arrests and Fatalities in the Metro Detroit Area During the COVID-19 Pandemic With Previous-Year Events.

This cross-sectional study compares trends in out-of-hospital cardiac arrests and fatalities in the Detroit area during the COVID-19 pandemic with year-earlier events for the same period.

Characteristics and Outcomes of Stroke Patients Transferred to Hospitals Participating in the Michigan Coverdell Acute Stroke Registry.

Background: Interhospital transfer of acute stroke patients is becoming increasingly important as regional stroke systems of care continue to evolve. We describe the characteristics and outcomes of stroke cases transferred to hospitals participating in the Michigan Coverdell Stroke Registry.

Methods And Results: Thirty-six hospitals participated in the Michigan registry during 2009 to 2011.

Assessment of the completeness and accuracy of case ascertainment in the Michigan Stroke Registry.

Background: Accurate case ascertainment is essential for clinical registries to be valid and representative. We assessed case ascertainment in the Michigan Stroke Registry by linking to a statewide hospital discharge database (Michigan Inpatient Database [MIDB]).

Methods And Results: In 2009, all ischemic stroke cases submitted by 30 registry hospitals were linked to ischemic stroke discharges (International Classification of Diseases, Ninth Revision code 433.

Hospital variation in thrombolysis times among patients with acute ischemic stroke: the contributions of door-to-imaging time and imaging-to-needle time.

Importance: Given the limited time window available for treatment with tissue plasminogen activator (tPA) in patients with acute ischemic stroke, guidelines recommend door-to-imaging time (DIT) within 25 minutes of hospital arrival and door-to-needle (DTN) time within 60 minutes for patients with acute ischemic stroke. Despite improvements in DITs, DTN times for tPA treatment in patients with acute ischemic stroke remain suboptimal.

Objectives: To examine the contributions of DIT and imaging-to-needle (ITN) time to delays in timely delivery of tPA to patients with acute ischemic stroke and to assess between-hospital variation in DTN times.
