FACTORS ASSOCIATED WITH CHRONIC PAIN CHARACTERISTICS ASSESSED USING THE McGILL PAIN QUESTIONNAIRE IN MAINTENANCE HEMODIALYSIS PATIENTS AT MILITARY HOSPITAL 103

Tóm tắt

Objectives: To evaluate the association between chronic pain characteristics assessed using the McGill Pain Questionnaire and selected clinical and laboratory parameters in maintenance hemodialysis (MHD) patients. Methods: A cross-sectional descriptive study was conducted on 131 patients with end-stage renal disease (ESRD) undergoing MHD at Military Hospital 103 from May 2024 to May 2025. Results: Chronic pain was highly prevalent among MHD patients, with a rate of 83.97%. Sex significantly influenced the total sensory-affective pain rating index (PRI-T), with higher scores observed in female patients (p = 0.02). Duration of hemodialysis was strongly associated with pain severity (p = 0.002), with total pain scores increasing with longer dialysis duration, particularly in patients undergoing MHD for more than 7 years. Longer duration of chronic pain was associated with higher total pain scores (p = 0.019). Age at pain onset also affected pain intensity, with patients experiencing pain onset at an older age more likely to report moderate to severe pain (p = 0.037). Conclusion: Chronic pain is highly prevalent in MHD patients and is associated with sex, hemodialysis duration, chronic pain duration, and age at pain onset. The McGill Pain Questionnaire is a useful tool for assessing pain severity and characteristics in this population.
