The Reality of AI Implementation

At the University of Pennsylvania Health System, an AI algorithm predicts patients' mortality risk to prompt oncologists to discuss end-of-life care. However, during the COVID-19 pandemic, the algorithm's accuracy declined by 7 percentage points, potentially affecting hundreds of patients 1

The Hidden Costs of AI

Nigam Shah, chief data scientist at Stanford Health Care, raises a pertinent question: "Everybody thinks that AI will help us with our access and capacity and improve care and so on. All of that is nice and good, but if it increases the cost of care by 20%, is that viable?" 1

The implementation and maintenance of AI systems require significant investments:

1. Continuous monitoring of algorithm performance
2. Regular updates to maintain accuracy
3. Specialized staff to manage and interpret AI outputs
4. Powerful computing resources for data processing

Challenges in AI Evaluation

Jesse Ehrenfeld, past president of the American Medical Association, points out the lack of standardized evaluation methods for AI in healthcare. "We have no standards," he states, highlighting the difficulty in comparing different AI tools' performance 1
