The aim of the present study was to assess and compare the sociodemographic characteristics and clinical features of patients referring to a university hospital's pain clinic with chronic ( ≥ 12 weeks) and subacute pain ( < 12 weeks).
In this cross-sectional study, 426 patients were included. Demographic variables including education level, marital and employment status, and risk factors such as obesity, diabetes mellitus, hypertension, cigarette smoking, and opium addiction were recorded. Also, sites of pain, pain quality and associated symptoms, and pain severity were assessed using a numerical rating scale. Each one of these variables was compared between the chronic and subacute pain groups.
Of the 426 studied patients, 292 (69%) had chronic pain and 134 (31%) reported subacute pain. Patients with chronic pain were older and had higher body mass indices. Additionally, self-employment was less frequent among the chronic pain group. The patients with chronic pain had a higher prevalence of addiction. The most commonly reported site of pain in all patients was the lower back (62.4%), followed by pain in the leg and foot (39.9%), knee (24.4%), and hip (18.8%). There were no statistically significant differences in pain sites between the two groups, except for knee pain, which was more common among the chronic pain group. The patients with chronic pain had a higher incidence of obscure and persistent pain, while those with subacute pain experienced more night pain.
About one-third of the patients referring to the pain clinic had subacute pain. The patients with chronic pain were older and more obese, had a higher prevalence of addiction, had more cases of knee pain, and reported more instances of obscure and persistent pain than those with subacute pain.
本研究旨在评估和比较转诊至大学医院疼痛门诊的慢性疼痛（≥12周）和亚急性疼痛（<12周）患者的社会人口学特征和临床特征。
在这项横断面研究中，纳入了426例患者。记录了包括教育水平、婚姻和就业状况等人口统计学变量，以及肥胖、糖尿病、高血压、吸烟和阿片成瘾等危险因素。此外，使用数字评分量表评估疼痛部位、疼痛性质和相关症状以及疼痛严重程度。对慢性疼痛组和亚急性疼痛组之间的每一个变量进行比较。
在426例研究患者中，292例（69%）患有慢性疼痛，134例（31%）报告为亚急性疼痛。慢性疼痛患者年龄较大且体重指数较高。此外，慢性疼痛组中个体经营的情况较少。慢性疼痛患者成瘾的患病率较高。所有患者中最常报告的疼痛部位是下背部（62.4%），其次是腿部和足部疼痛（39.9%）、膝盖疼痛（24.4%）和臀部疼痛（18.8%）。除膝盖疼痛在慢性疼痛组中更常见外，两组之间的疼痛部位在统计学上无显著差异。慢性疼痛患者出现模糊和持续性疼痛的发生率较高，而亚急性疼痛患者夜间疼痛更多见。
转诊至疼痛门诊的患者中约三分之一患有亚急性疼痛。与亚急性疼痛患者相比，慢性疼痛患者年龄更大、更肥胖，成瘾患病率更高，膝盖疼痛的病例更多，且报告的模糊和持续性疼痛情况更多。
