This study investigates whether individuals who have sustained an electrical injury (EI) are diagnosed with unspecified pain or pain related to the musculoskeletal system in the years following the injury.
Individuals listed in Danish registers as having sustained EIs were matched for sex, age, and year of injury in a cohort study with individuals having experienced dislocations/sprains (match 1), eye injuries (match 2), and a sample of individuals with the same occupation without a history of electrical injuries (match 3). Outcomes were unspecified pain and unspecified soft tissue disorders. Conditional logistic regression and conditional Cox regression were applied.
We identified 14,112 individuals who sustained EIs. A higher risk of both outcomes was observed for all three matches, and was highest at the 6- and 12-month follow-ups. The risk of both outcomes was considerably higher for match 3.
This study confirms that exposure to EIs increases the risk of being diagnosed with unspecified pain or unspecified soft tissue disorders both at short and long terms. Our results also showed that the risk of unspecified pain as sequelae is related to the severity of the injury.
本研究旨在调查电击伤（EI）患者在受伤后数年是否被诊断为未特指的疼痛或与肌肉骨骼系统相关的疼痛。
在一项队列研究中，将丹麦登记册中列出的 EI 患者按性别、年龄和受伤年份与经历过脱位/扭伤（匹配 1）、眼部损伤（匹配 2）的个体以及同一职业但无 EI 史的个体样本（匹配 3）进行匹配。结局为未特指的疼痛和未特指的软组织疾病。采用条件逻辑回归和条件 Cox 回归进行分析。
我们确定了 14112 名发生 EI 的个体。所有三种匹配都观察到这两种结局的风险更高，且在 6 个月和 12 个月的随访中风险最高。匹配 3 的这两种结局的风险明显更高。
本研究证实，暴露于 EI 会增加在短期和长期内被诊断为未特指的疼痛或未特指的软组织疾病的风险。我们的结果还表明，未特指的疼痛作为后遗症与损伤的严重程度有关。
