International Study Reveals AI Improves Physician Clinical Decision-Making Across Diverse Healthcare Settings
An international study published in npj Digital Medicine found that physicians utilizing a large language model (LLM), specifically GPT-4o, demonstrated improved performance on simulated clinical cases compared to those without AI assistance. The randomized controlled trial involved 249 physicians across Kenya, Indonesia, and the Netherlands, representing lower-middle-income, upper-middle-income, and high-income healthcare systems. Physicians were tasked with completing four simulated primary care cases covering cardiovascular, respiratory, musculoskeletal, and viral conditions. The results showed statistically significant improvements in average scores across all three countries: an 18 percentage point increase in Kenya, a 10.7 point increase in Indonesia, and a 7.2 point increase in the Netherlands. Researchers noted that differences in physician specialization and training might have contributed to the varying degrees of improvement, particularly in Kenya where a higher percentage of participants were e...
