Short description of contents:

IntroductionPain is one of the most frequently reported symptoms in hemodialyzed (HD) patients, with prevalence rates between 33% and 82%. Risk factors for chronic pain in HD patients are older age, long-lasting dialysis history, several concomitant diseases, malnutrition, and others. However, chronic pain assessment in HD patients is rarely performed by specialists in pain medicine, with relevant consequences in terms of diagnostic and treatment accuracy. Furthermore, no study has used the recently introduced International Association for the Study of Pain (IASP) pathophysiological classification.MethodsIn this observational, cross-sectional study in a tertiary HD center in Northern Italy, we analyzed data regarding HD patients, evaluated for 5 months in 2021 by specialists in pain medicine and aimed to identify and characterize chronic pain according to the IASP definition and the last 2019 classification of chronic pain for ICD-11. Pain severity was evaluated by the pain severity score of the brief pain inventory tool.ResultsAmong 213 patients, 65 (31%) suffered from chronic pain. The average age was 73.1 years; 55.5% of the patients were male; 53.7% had diabetes, and 39.2% had arterial hypertension. Of the 54 patients subjected to an in-depth evaluation, data regarding 113 pain diagnoses were extracted, particularly related to osteoarthritis, obliterating arterial disease, and low back pain with or without radiculopathy. On the basis of these diagnoses, the pain classification according to the IASP pathophysiological definition highlighted a predominant nociceptive pain type (53.9% of all the diagnoses), followed by neuropathic (22.1%), mixed (22.1%), nociplastic (2.6%), and idiopathic (2.6%) pain. According to the IASP classification for ICD-11, the clinical diagnosis of chronic pain secondary to obliterating arterial disease and diabetes-related foot ulcers could not be assigned to any diagnostic category as a result of the lack of a specific item in the aforementioned classification.ConclusionThis study confirmed that chronic pain is a common, burdening issue in hemodialysis patients and that it is of a prevalent nociceptive nature. Our study highlights some limitations of the last IASP ICD-11 classification, especially the lack of specific items for some pain features that are very frequent in hemodialysis patients, and not only in that population. Finally, this study underlines the importance of mutual collaboration between pain physicians and nephrologists for the well-being of patients of high clinical complexity, such as those undergoing chronic hemodialysis.
