Summary
A new pain point system scale (PPSS) effectively assesses postoperative pain in retrospective studies. This tool correlates well with established pain scales, offering a reliable method for pain evaluation.
Area of Science:
- Anesthesiology and Pain Management
- Medical Informatics
Background:
- Standard pain assessment tools face limitations in retrospective studies.
- A need exists for validated instruments to evaluate historical pain data accurately.
Purpose of the Study:
- To introduce and validate a novel pain assessment tool, the pain point system scale (PPSS).
- To evaluate the PPSS's utility for assessing postoperative pain in retrospective research settings.
Main Methods:
- Postoperative pain episodes were assessed using visual analog, numerical rating, verbal rating scales, and the PPSS.
- An artificial neural network system aided in analgesic classification based on clinical data.
- Statistical analyses, including correlation coefficients (Spearman's and Pearson's), were employed to validate the PPSS against existing scales.
Main Results:
- The PPSS assigns points based on administered analgesics: paracetamol (1 point), NSAIDs/codeine (3 points), and opioids (7 points).
- A strong, linear correlation was observed between the PPSS and the visual analog scale (rho=0.715, P<0.001; Pearson=0.631, P<0.001).
Conclusions:
- The pain point system scale (PPSS) demonstrates strong correlation with established pain assessment methods.
- The PPSS is a reliable and safe tool for evaluating postoperative pain in retrospective studies.

01:25Analgesia 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...
