Traditionally, finding effective drugs has been uncertain and time-consuming, with less than 10% of candidates passing clinical trials. But AI is changing that, offering a way to greatly increase the chances of finding new drugs that can be turned into real treatments. As Pfizer’s Vice President and Head of Information Management Boris Braylyan puts it in the quote below, AI possesses the potential to contribute significantly to identifying which medications are not worth pursuing.
“Using data to make faster decisions on a medicine’s potential would allow us to re-allocate resources, dollars, and expertise to the next promising candidate faster.”
The magic of AI lies in its ability to analyze complex genetic data and predict how different traits and diseases develop. This prediction capability is crucial in drug discovery, helping researchers identify the right compounds that could become new medicines.
In a groundbreaking feat, an AI-engineered drug molecule named DSP-1181, aimed at treating patients with obsessive-compulsive disorder (OCD), has entered human trials within a mere 12 months, defying the typical four to six year timeline. Crafted via collaboration between the British startup Exscientia and Japanese pharmaceutical giant Sumitomo Dainippon Pharma, this drug was discovered by employing algorithms that combed through potential compounds within an extensive database. Notably, this milestone prefaces a transformative era for drug discovery, showcasing AI's capacity to accelerate drug development, thereby enhancing the efficiency of delivering effective treatments to patients, and potentially saving both time and money in the process.
4. Streamlining Administrative Tasks
AI isn't just changing how doctors treat patients—it's also transforming the way healthcare information is managed and stored according to this study. Natural Language Processing (NLP), which is a specialized field of AI, serves as a bridge between human language and computational understanding, essentially allowing computers to grasp the meaning from human language just like how people understand each other. Its relevance is particularly pronounced in transforming clinicians' narratives into structured information.
For example, Microsoft’s Nuance developed a medical scribe application named Dragon Ambient eXperience (DAX) Express. Powered by OpenAI's GPT-4, this integration of AI aims to revolutionize healthcare by automating note-taking during doctor-patient interactions, by providing the medical profession with a document that emphasizes the relevant medical concerns while excluding casual conversation, and permits post-interaction edits to ensure comprehensive content. This approach relieves administrative duties from physicians, enabling them to concentrate solely on patient interaction.
Overall, NLP represents a pivotal force that streamlines administrative functions within healthcare, leading to smoother operations and a better experience for patients and doctors alike.
5. Predicting Outbreaks and Preventive Care
AI isn't just about treating individuals—it's also about keeping entire populations healthy. By analyzing data from various sources, AI holds potential to predict disease outbreaks and trends.
AI can revolutionize public health surveillance and response by addressing the core challenges in this field. Public health surveillance heavily relies on data to detect health anomalies and disease outbreaks. The hurdles lie in sourcing data effectively and analyzing it to identify meaningful patterns. For example, as this study suggests, AI can expand traditional statistical data analytics to handle various data types like text, images, and videos, using techniques such as NLP and image processing. Furthermore, public health surveillance focuses on timely risk assessment, anomaly detection, and trend prediction for epidemics. AI, particularly machine learning, can be employed to analyze intricate surveillance data streams to offer insights beyond the current conventional means.
As a response to the challenges of COVID-19, research is exploring the idea of using AI together with traditional methods to predict how the disease spreads and identify potential outbreaks in the future. In an effort to examine the efficacy of AI to predict patient outcomes, researchers trained a machine-learning model on data from 51,500 COVID-19 patients, specifically on eight characteristics gathered from individuals, such as factors like age, gender, verified exposure to an infected person, and five symptoms including cough, fever, sore throat, shortness of breath, and headache.
