Deep neural network architectures for forecasting analgesic response.

Area of Science:

• * Computational methods in medicine
• * Pharmacology and pain management

Background:

• * Individual variability in analgesic drug response necessitates trial-and-error, prolonging effective pain management.
• * Adverse events, like post-operative urinary retention (POUR), complicate acute pain treatment.
• * Accurate prediction of pain trajectories and adverse events is crucial for optimizing patient care.

Purpose of the Study:

• * To compare the efficacy of conventional machine learning and neural network models in forecasting postoperative pain and analgesic use.
• * To evaluate the predictive performance of these models for the risk of post-operative urinary retention (POUR).
• * To identify optimal computational strategies for enhancing postoperative pain management.

Main Methods:

• * Comparative analysis of traditional machine learning algorithms and advanced neural network architectures.
• * Application of models to forecast temporal patterns of patient-reported pain and prescribed analgesic administration.
• * Utilizing models to predict the likelihood of developing post-operative urinary retention (POUR).

Main Results:

• * Simpler machine learning approaches demonstrated potentially superior predictive performance compared to complex neural networks.
• * All evaluated computational techniques showed promise in forecasting key aspects of postoperative recovery.
• * Models were effective in predicting temporal pain patterns, analgesic consumption, and POUR risk.

Conclusions:

• * Machine learning, particularly simpler models, offers a promising avenue for personalized postoperative pain management.
• * These predictive tools can aid clinicians in anticipating patient responses and potential complications like POUR.
• * The integration of such strategies could lead to more efficient and effective acute pain treatment protocols.
