Artificial intelligence (AI) researchers at social media company Facebook claim to have developed software that can forecast the probability of a Covid-19 patient's symptoms escalating, based on their chest x-rays.
The Facebook team worked with academics in New York University Langone Health's predictive analytics unit and radiology department.
The researchers said the new software could help prevent doctors from sending at-risk patients home too early, as well as helping hospitals plan for oxygen demand.
The collaborators said they devised three machine learning models: one predicts deterioration based on a single chest x-ray, the second performs the same task with a sequence of x-rays, and the third employs one x-ray to anticipate how much supplemental oxygen a patient might require.
The team said the sequential chest x-ray-based model could predict a patient's needs up to 96 hours in advance.
