The study quantifies the association between a range of bio-psychosocial factors and the presence of persistent pain, pain severity and pain interfering with normal work activities in a cohort of 168 patients with a range of non-life-threatening orthopaedic injuries. Participants were recruited following presentation to 1 of 4 Victoria hospitals for treatment for their injury and followed until 6 months postinjury. Multivariate analysis was employed to determine factors associated with pain outcomes, 6 months postinjury. The prevalence of pain was common; 54% of participants reported the presence of persistent pain at 6 months, with the majority (87%) reporting that pain interfered to an extent with their normal work activities. High initial pain, external attributions of responsibility for the injury, and psychological distress were found to be significant independent predictors of the presence of all 3 outcomes. In addition, poor recovery expectations was found to be a significant predictor of pain-related work disability and being injured at work a significant predictor of pain severity. Many of these factors are potentially modifiable and should alert the clinician about the need for interventions in order to prevent the development of pain chronicity.
This study has quantified determinants of pain, 6 months after non-life-threatening acute orthopaedic trauma. Psychosocial factors strongly predicted persistent pain, pain-related work disability, and pain severity. These findings may assist clinicians to determine the need for, and likely effectiveness of, individual pain-management approaches in this population.
本研究在一组患有多种非危及生命的骨科损伤的患者中,量化了一系列生物心理社会因素与持续性疼痛、疼痛严重程度以及疼痛对正常工作活动的干扰之间的关联。参与者在因伤就诊于 4 家维多利亚医院中的 1 家接受治疗后被招募,并随访至受伤后 6 个月。采用多变量分析确定与受伤后 6 个月时疼痛结局相关的因素。疼痛的患病率较高;54%的参与者报告在 6 个月时存在持续性疼痛,大多数(87%)报告疼痛在一定程度上干扰了他们的正常工作活动。高初始疼痛、对受伤责任的外部归因以及心理困扰被发现是所有 3 种结局存在的显著独立预测因素。此外,不良的康复预期被发现是疼痛相关工作残疾的显著预测因素,而在工作中受伤是疼痛严重程度的显著预测因素。这些因素中有许多是潜在可改变的,这应该提醒临床医生需要进行干预,以防止疼痛慢性化的发展。
本研究量化了非危及生命的急性骨科创伤后 6 个月时疼痛的决定因素。心理社会因素强烈预测持续性疼痛、与疼痛相关的工作残疾和疼痛严重程度。这些发现可能有助于临床医生确定该人群中个体疼痛管理方法的必要性和可能的有效性。
