Insights
This study developed an artificial neural network (ANN) model to predict unplanned patient readmission (UPRA) in pneumonia patients. The ANN model achieved high accuracy, enabling early risk identification for better patient care.
Area of Science:
- Healthcare Informatics
- Clinical Prediction Modeling
- Artificial Intelligence in Medicine
Background:
- Unplanned patient readmission (UPRA) presents a significant financial burden and quality concern in healthcare.
- Current clinical practices lack effective tools for identifying patients at high risk of UPRA during hospitalization.
Purpose of the Study:
- To develop and validate a predictive model for early detection of 14-day UPRA in pneumonia patients.
- To compare the performance of artificial neural network (ANN) and convolutional neural network (CNN) models for UPRA prediction.
- To create a user-friendly application for real-time UPRA risk assessment.
Main Methods:
- Utilized a dataset of 21,892 pneumonia patients from three Taiwanese hospitals (2016-2018).
- Developed and compared ANN and CNN models using training (70%) and testing (30%) datasets.
- Extracted 17 feature variables for model development and evaluated performance using Area Under the Curve (AUC).
Main Results:
- The ANN model demonstrated a high Area Under the Receiver Operating Characteristic Curve (AUC) of 0.75 with 17 extracted features.
- ANN model performance (AUC=0.73) surpassed CNN model performance (AUC=0.50).
- A functional application was successfully developed for predicting UPRA.
Conclusions:
- The developed ANN model effectively predicts 14-day UPRA in pneumonia patients.
- The prediction tool can assist clinicians in identifying high-risk individuals for proactive intervention.
- Early detection via the app facilitates timely preparedness plans, potentially reducing readmission rates.
Abstract:
Unplanned patient readmission (UPRA) is frequent and costly in healthcare settings. No indicators during hospitalization have been suggested to clinicians as useful for identifying patients at high risk of UPRA. This study aimed to create a prediction model for the early detection of 14-day UPRA of patients with pneumonia. We downloaded the data of patients with pneumonia as the primary disease (e.g., ICD-10:J12*-J18*) at three hospitals in Taiwan from 2016 to 2018. A total of 21,892 cases (1208 (6%) for UPRA) were collected. Two models, namely, artificial neural network (ANN) and convolutional neural network (CNN), were compared using the training (n = 15,324; ≅70%) and test (n = 6568; ≅30%) sets to verify the model accuracy. An app was developed for the prediction and classification of UPRA. We observed that (i) the 17 feature variables extracted in this study yielded a high area under the receiver operating characteristic curve of 0.75 using the ANN model and that (ii) the ANN exhibited better AUC (0.73) than the CNN (0.50), and (iii) a ready and available app for predicting UHA was developed. The app could help clinicians predict UPRA of patients with pneumonia at an early stage and enable them to formulate preparedness plans near or after patient discharge from hospitalization.
