Is ChatGPT smarter than a Doctor ?


The advent of artificial intelligence (AI) in healthcare has raised both eyebrows and expectations. While AI offers promise for automating routine tasks and data analysis, questions about its applicability in nuanced medical practices persist. A recent study presented at the Royal College of General Practitioners (RCGP) Annual Conference 2023 brought these questions into sharp focus. The research revealed that ChatGPT failed the UK's National Primary Care examinations. So, what does this mean for the future of AI in healthcare, particularly in the complex realm of primary care?

Shathar Mahmood and Arun James Thirunavukarasu, two Indian junior doctors from UK, led a team to examine ChatGPT's performance using the Membership of the Royal College of General Practitioners Applied Knowledge Test. This is a part of the UK’s specialty training for becoming a general practitioner (GP). It's a multiple-choice assessment that tests the knowledge required for general practice within the context of the UK's National Health Service (NHS). The algorithm's overall performance was slightly below par, scoring 10% less than the average RCGP pass mark in recent years.

The study highlights the limitations of AI when it comes to making complex medical decisions. Sandip Pramanik, a GP from Watford, noted that the study "clearly showed ChatGPT's struggle to deal with the complexity of the exam questions." In essence, the limitations of ChatGPT lie in its inability to grasp the intricate web of human factors involved in medical decision-making, something that general practitioners are trained extensively to handle. 

Interestingly, the study also found that ChatGPT can generate 'hallucinations,' or novel explanations, which are inaccurate but presented as factual. This is concerning as non-experts would not be able to discern these hallucinations from actual facts. Hence, the risk of misinformation increases, particularly in an age when medical advice is frequently sought online. 

My Concluding Thoughts

So, does AI have a future in healthcare? Certainly. But replacing human clinicians in primary care? Probably not anytime soon. Mahmood succinctly stated that larger and more medically specific datasets are needed to improve AI systems' accuracy in this field. This suggests that while AI has its place in healthcare, that place is not in the replacement of human decision-making complexity and nuance. Instead, it serves as a tool that can assist but not usurp the role of healthcare professionals.

Let's remember, healthcare is not just about data points and binary answers; it’s about understanding the intricate nuances of human emotions, conditions, and complexities, something AI is far from mastering.
