For instance, algorithms can analyze data from electronic health records (EHRs) to identify the most effective treatment pathways for specific patient demographics. This dynamic approach not only reduces the chances of adverse reactions but maximizes the effectiveness of treatments.

One notable real-world example is the use of AI by Flatiron Health, which employs machine learning to assist oncologists in deciding the best cancer treatment plans based on real-world evidence collected from patient records. By incorporating the experiences of thousands of patients, AI develops insights that can lead to better-targeted therapies.

2.3 Monitoring and Follow-Up Care

AI is fostering a new era in patient monitoring and follow-up care through wearable technology and predictive analytics. Devices that monitor vital signs, physical activity, and sleep patterns can provide invaluable data that AI systems analyze to offer insights into a patient’s health in real-time.

Technologies like cardiac monitors, glucose sensors for diabetes patients, and wearable fitness trackers allow healthcare providers to monitor chronic conditions more effectively. They can alert healthcare professionals to any unusual patterns that could warrant further investigation or intervention.

In a case study conducted by the American College of Cardiology, patients with heart failure who used AI-powered wearable devices had fewer hospital readmissions compared to those who were not monitored. As AI continues to develop, the ability to remotely monitor patients will not only improve health outcomes but also reduce the costs associated with frequent hospital visits.
