Solution Overview

Problem

Current medical resource forecasting methods in healthcare settings are inadequate due to imprecision and inaccuracy, particularly in ICU resource predictions, often relying on census and conventional health-care variables that fail to account for evolving patient needs and are influenced by biased human evaluation.

Innovation Solution

A computer-readable storage medium with instructions to build and execute a Dynamic Bayes Network (DBN) model for predicting resource needs, using historical medical data to generate a simplified predictive model that forecasts resource requirements, such as nurse staffing and equipment needs, by processing and refining data through Bayesian node estimation and ARIMA modeling.

1Measurement precision

If conventional resource forecasting methods using census and health-care variables are used, then the forecasting process is simple and easy to implement, but the precision and accuracy of resource predictions are inadequate

Engineering Contradiction:

Solution Approach 1:

The patent transforms the forecasting approach by changing from conventional static parameters (census, health-care variables) to dynamic parameters captured through Electronic Health Record data. This parameter transformation enables more accurate predictions of resource needs while accounting for evolving patient conditions throughout their hospital stay.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces manual forecasting methods with an automated machine learning system that processes EHR data. This substitution eliminates human bias and subjectivity from resource forecasting, providing more objective and accurate predictions through computational algorithms rather than human evaluation.

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

2Reliability

If conventional forecasting methods are used, then the implementation is straightforward, but the forecasts are influenced by biased human evaluation and fail to account for evolving patient needs

Engineering Contradiction:

Solution Approach 1:

The patent replaces human-based forecasting with an automated machine learning system that processes Electronic Health Record data. This substitution eliminates human bias and subjectivity from resource forecasting, providing more objective and reliable predictions through computational algorithms rather than human evaluation.

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

Solution Approach 2:

The machine learning system autonomously processes EHR data and generates resource forecasts without requiring manual human intervention. The system automatically learns from historical data patterns and applies this knowledge to predict future resource needs, enabling self-service forecasting that improves reliability while reducing dependence on human operators.

Inventive Principle:
Principle #25Self-service

AI summary

A predictive model forecasts a medical resource need by making use of empirical Bayes estimation methods to determine a Dynamic Bayes Network (DBN) model. Exemplary resource needs that may be forecast include nurses, ventilators, hospital rooms, etc. The DBN model is estimated from retrieved data that is related to the resource to be forecast. The DBN model is simplified and a predictive model is generated based on the simplified model. The predictive model runs to forecast the predicted need for the resource. Embodiments are directed toward a predictive model development system that instructs an operator as to the structure of the data so that a model may be tailored based on the understanding of the operator. Embodiments are directed toward a model running system that indexes available models and also employs powerful statistical analysis techniques on behalf of a user to generate a predictive model with little or no user involvement in low-level modeling details.
