Solution Approach 1:

The patent replaces traditional manual discharge planning methods with an automated machine learning-based prediction system. The system uses trained models to automatically analyze patient data, predict discharge timing and destinations, and generate recommendations, substituting human judgment and manual processes with computational algorithms that provide more accurate and timely predictions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs discharge planning predictions in advance by analyzing patient data early in the hospital stay and continuously updating predictions as new data becomes available. This preliminary action allows care providers to prepare discharge arrangements, coordinate with post-acute facilities, and plan resource allocation before the actual discharge date, eliminating last-minute delays.

Inventive Principle:

AI summary

Techniques are described for predicting information regarding expected time of occurrence of clinical events based on longitudinal patient data. According to an embodiment, a method can include clustering, by a system comprising a processor, training data samples corresponding to different patients that experienced a clinical event into different patient groups as a function of different defined timeframes within which the clinical event occurred. The method further comprises employing, by the system, a first machine learning process to train a classification model using the training data samples to predict the different patient groups to which the training data samples respectively belong, and employing, by the system, a second machine learning process to train a clinical time to event model using the training data samples to predict an expected duration of time until occurrence of the clinical event as a function of the different patient groups.
