Artificial intelligence (AI) is making significant strides in the healthcare sector, particularly in predicting ICU needs for COVID-19 patients. Researchers at various institutions have developed AI models with impressive accuracy and sensitivity, outperforming conventional scoring tools in clinical studies.
One such AI model, developed by a team at an unspecified institution, achieved a sensitivity of 97.5% and an overall accuracy of 93.8% in differentiating COVID-19 cases in emergency ICU patients. These models have also shown strong predictive performance in anticipating critical events such as sepsis onset and mortality related to ICU sepsis.
Despite these promising results, the clinical implementation and operationalization of these AI models remain in early stages. A recent systematic review revealed that the majority of AI studies on ICU applications are still in development, with only about 2% of models having progressed to clinical integration. Many studies also suffer from high risk of bias and lack of prospective validation.
AI tools for ICU use, such as those predicting respiratory failure and weaning from mechanical ventilation, have shown statistically significant improvements in patient outcomes in clinical environments. However, more widespread operational use and robust clinical trials are needed.
Specific to COVID-19, AI models that incorporate routinely available data, including imaging biomarkers, have been developed to predict mortality risk at hospital admission, supporting early triage and ICU resource allocation. AI can also assist in emergency departments by anticipating which patients will require hospital or ICU admission hours earlier than traditional methods, potentially improving patient flow and care timeliness.
Elsewhere in the realm of AI and healthcare, researchers at Microsoft have created an AI system that can identify common bugs in Python code. This system operates by creating two networks: one meant to create bugs in existing code, and the other meant to find bugs in code.
In a different development, Honda is partnering with the Ohio Department of Transportation to monitor road conditions using connected car technology. The partnership will use GPS systems and cameras to collect data on poor road conditions and report their location, type, and severity to transportation officials.
At Massachusetts General Hospital, researchers have developed a predictive model that can be used by doctors to screen patients for lung cancer and start treatment plans before the disease progresses. Another model created by the same team can detect signs of lung cancer in asymptomatic patients from a blood sample.
Finally, researchers at the University of Exeter have developed an AI system that can predict a patient's chances of developing dementia within the next 2 years with 92 percent accuracy. The AI system was trained with medical data from 15,300 patients.
In conclusion, AI is proving to be a valuable tool in various aspects of healthcare, from predicting ICU needs for COVID-19 patients to identifying potential risks for lung cancer and dementia. While clinical implementation and operationalization remain challenges, the potential benefits of these AI models are clear and warrant continued research and development.
