Use Case: Predicting Hospital Readmission Risk with DataRobot

In this article, we’ll explain how to use predictive models for better outcomes and lower cost-of-care.
What’s the problem?
The federal government imposes penalties (in the form of withholding payment) based on a hospital’s readmission rate within 30 days of discharge. In 2017, Medicare expected to withhold $528 million, about $108 million more than the previous year. These penalties would punish 2,597 hospitals–more than half of the nation’s facilities. According to a Kaiser Health News analysis, while this is roughly the same number as in 2015, the average penalty is increasing by 20%. The costs of readmission can be staggering.
The challenge and solution
How do you identify patients with a high readmittance risk so that you can take preventive measures prior to or after discharge? It is impractical and cost prohibitive to monitor every patient after discharge. You could, however, use the hospital’s existing data to build predictive models that help prioritize patients based on readmission risk. The overall benefits from a readmission risk model are better patient outcomes, reduction in cost-of-care, and penalty avoidance. Using automated machine learning to develop the model, content experts can frame the problem and data scientists can focus on application and deployment. In this way, you develop an adaptable model that addresses provider, patient, and business needs.
Marcy is a clinical analyst for a large healthcare network; member hospitals are seeing a growing number of 30-day readmissions. Marcy has been tasked with identifying patients who have a high risk of readmittance. Using the network’s electronic health record (EHR) data, Marcy will build a predictive model to proactively identify those at risk for hospital readmission. With DataRobot, her model can show her–and the care providers–the basis for the prediction.

Healthcare organizations are increasingly adopting AI to improve the patient experience, along with business outcomes. According to PWC Global, AI is transforming healthcare organizations with improvements to the early detection of diseases, research, training, and more. Medical groups that adopt AI can treat patients quickly and effectively while saving time, money, and resources. The infographic below shows common use cases…
HIMSS20 is around the corner and, like most, I am contemplating the conversations I will have there and am reflecting on the impact of AI on the future of healthcare. While top trends shaping the healthcare industry include consumerism, expanding value-based care programs, increasing volumes of previously unavailable data, and a continued shortage of healthcare professionals, I don’t consider AI…
At DataRobot, we strongly believe AI is a force for good. From the way deep learning algorithms can create art and writing to its applications for health and medicine, as well as astonishing head-to-head match-ups between AIs and humans in games, AI has made enormous strides towards imitating human behavior. At the same time, we recognize that AI is a…
