Analgesia and Pain Management

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Area of Science:

Medical Informatics
Artificial Intelligence in Healthcare
Pain Management

Background:

Postoperative pain remains a significant clinical challenge.
Effective pain management requires identifying at-risk patients for targeted interventions.
Machine learning (ML) offers a data-driven approach for risk stratification.

Purpose of the Study:

To develop and validate an ML-based risk assessment model for predicting poor postoperative pain outcomes.
To identify high-risk patients early without requiring additional data collection.
To leverage existing electronic medical record (EMR) data for predictive modeling.

Main Methods:

Utilized EMR data from over 70,000 in- and outpatient cases.
Developed and compared various ML models using 807 features.
Employed the gradient boost machine (GBM) algorithm for optimal performance.

Main Results:

The GBM model demonstrated strong predictive performance with an area under the receiver operating characteristic curve (AUROC) of 0.82 on hold-out test data.
The model effectively identified patients at risk for poor pain outcomes using routine EMR data.
Achieved good predictive accuracy without necessitating novel data acquisition.

Conclusions:

The developed GBM model shows significant potential for early identification of patients susceptible to severe postoperative pain.
This AI-driven tool can facilitate proactive, personalized pain management strategies.
Further validation in real-world clinical settings is crucial to confirm its practical utility and impact.
