Recurrences of injuries are common and have significant socioeconomic consequences; it is important to identify associated risk factors as potential opportunities for prevention. This study was conducted to identify risk factors for low back pain (LBP) recurrence and the extent that variation in recurrence definition impacts identified risk factors. Patients with new claims for LBP reported in New Hampshire to a workers' compensation provider were selected (n = 2023) with a minimum of 3-year follow up. Alternative definitions of recurrence included a new episode of medical care and a new episode of lost work time (work disability). Risk factors better predicted disability-based than treatment-based recurrence. Longer durations of the initial episode of care or work disability were the most powerful predictors of recurrence, implying that shorter episodes of care and early return to work contribute to better outcomes.
损伤复发很常见，且会产生重大的社会经济后果；识别相关风险因素作为潜在的预防机会很重要。本研究旨在确定腰痛（LBP）复发的风险因素，以及复发定义的差异对所确定的风险因素的影响程度。选取了向新罕布什尔州一家工伤赔偿机构报告新发LBP索赔的患者（n = 2023），并进行了至少3年的随访。复发的替代定义包括新的医疗护理事件和新的误工时间事件（工作残疾）。与基于治疗的复发相比，风险因素对基于残疾的复发预测效果更好。初始护理或工作残疾事件的持续时间越长，复发的最强有力预测因素，这意味着较短的护理事件和早日重返工作有助于取得更好的结果。
