The AI-powered system rapidly analyzes brain CT scans of stroke patients upon their arrival at the hospital. Within just one minute, it can identify the type and severity of the stroke, enabling doctors to make swift decisions about the most appropriate treatment course

Dramatic Improvement in Treatment Times and Outcomes

The implementation of this AI technology has led to remarkable improvements in stroke treatment:

  1. Reduced Time to Treatment: The average time between a patient's hospital admission and the start of life-saving treatment has been cut by 60 minutes, from 140 minutes to 79 minutes

    2

    .

  2. Increased Recovery Rates: The proportion of patients recovering with no or only slight disability - defined as achieving functional independence - has tripled from 16% to 48%

Nationwide Implementation

The AI tool has been rolled out to all 107 NHS stroke centers in England, potentially benefiting the 80,000 people who experience a stroke in the country each year

. He emphasized the critical nature of rapid diagnosis and treatment in stroke care.

Broader Context and Future Implications

This development comes at a crucial time, as stroke incidence in England has increased by almost a third over the past 20 years. In 2023-24, more than 110,000 people were diagnosed with a stroke

. The successful implementation of AI in stroke care could pave the way for similar advancements in other areas of healthcare.

The UK government is also taking steps to accelerate the adoption of AI in healthcare. In June, it co-founded an international network of health regulators focusing on AI use, aiming to get "trusted AI tools safely into clinics faster"
