Best Practice Recommendations for Stroke Vascular Imaging During Iodinated Contrast Shortage

Area of Science:

• Neurology
• Radiology
• Healthcare Supply Chain Management

Background:

• A COVID-19 outbreak in Shanghai caused a temporary shutdown of a major iodinated contrast agent factory.
• This resulted in a worldwide shortage of essential contrast agents, including Omnipaque and Visipaque.
• The shortage significantly impacted healthcare providers, including Comprehensive Stroke Centers.

Purpose of the Study:

• To describe the impact of the iodinated contrast agent shortage on stroke care.
• To propose best practice recommendations for managing such shortages.
• To provide a blueprint for other hospital systems facing supply chain disruptions.

Main Methods:

• Formation of a multidisciplinary working group (vascular neurology, diagnostic neuroradiology, neurovascular surgery).
• Revision of protocols and development of local guidelines for imaging modalities.
• Focus on CT angiography, CT perfusion, and digital subtraction angiography for stroke patients.

Main Results:

• Established parameters and local guidelines to mitigate the contrast agent shortage.
• Demonstrated the ability to adapt and maintain high-quality stroke care despite supply chain issues.
• Developed a framework for managing future medical supply shortages.

Conclusions:

• The developed recommendations can serve as a blueprint for other institutions.
• Proactive protocol revision is crucial for maintaining patient care during supply chain disruptions.
• Multidisciplinary collaboration is key to effectively navigating medical supply shortages.
