An emergency department diagnostic protocol for patients with transient ischemic attack: a randomized controlled...

Area of Science:

• Emergency Medicine
• Neurology
• Health Services Research

Background:

• Transient ischemic attack (TIA) diagnosis and management traditionally involve lengthy inpatient stays.
• Optimizing TIA patient care pathways is crucial for reducing healthcare costs and improving efficiency.
• Emergency department (ED) observation units offer a potential setting for rapid TIA assessment.

Purpose of the Study:

• To compare the effectiveness of an accelerated diagnostic protocol (ADP) versus traditional inpatient admission for TIA patients.
• To evaluate differences in length of stay, healthcare costs, and clinical outcomes between the two management strategies.
• To determine if ADP in an ED observation unit is a viable and cost-efficient alternative for TIA management.

Main Methods:

• A prospective randomized study involving 149 TIA patients with normal initial workups.
• Patients were randomized to either an accelerated diagnostic protocol (ADP) or traditional inpatient admission.
• Outcomes measured included length of stay, 90-day total direct cost, recidivism, and clinical events.

Main Results:

• The ADP group had a significantly shorter median length of stay (25.6 hours vs. 61.2 hours) and lower 90-day costs ($890 vs. $1,547).
• More ADP patients received timely carotid imaging and echocardiography.
• Both groups demonstrated comparable rates of return visits, subsequent strokes, and major clinical events.

Conclusions:

• An accelerated diagnostic protocol for TIA is more efficient and cost-effective than traditional inpatient admission.
• This protocol achieves clinical outcomes comparable to inpatient care.
• ED observation units can effectively manage selected TIA patients, reducing resource utilization.
