To provide evidence of predictors for sickness absence in patients with non-specific chronic low back pain (CLBP), distinguishing predictors aimed at the decision to report sick (absence threshold) and decision to return to work (return to work threshold).
Medical and psychological databases were searched, as well as citations from relevant reviews. In- and exclusion criteria were applied. Two reviewers assessed the methodological quality of the papers independently.
Many different predictors were studied, and few factors were studied more than once. Consistent evidence was found for own expectations of recovery only as predictor for the decision to return to work. Patients with higher expectations had less sickness absence at the moment of follow-up measurement. As expected, different predictors were found aiming at the absence threshold or the return to work threshold. Furthermore, predictors varied also with the measurement instruments used, timing of follow-up measurements, and definition of outcomes. Until now, too few studies are available to overcome several potential sources of heterogeneity.
No core set of predictors exists for sickness absence in general. The characteristics of the study including the decision to report sick or to return to work determined the influence of several predictors on sickness absence in patients with CLBP. Further research and use of a core set of measurements and uniform definitions are needed to predict sickness absence and return to work in patients with CLBP.
提供非特异性慢性腰痛（CLBP）患者病假预测因素的证据，区分旨在决定报告病假（缺勤阈值）和决定重返工作岗位（重返工作阈值）的预测因素。
检索医学和心理学数据库以及相关综述的参考文献。应用纳入和排除标准。两名评审员独立评估论文的方法学质量。
研究了许多不同的预测因素，很少有因素被重复研究。仅发现自身对康复的期望作为重返工作决定的预测因素有一致的证据。期望较高的患者在随访测量时病假较少。正如预期的那样，发现了针对缺勤阈值或重返工作阈值的不同预测因素。此外，预测因素还因所使用的测量工具、随访测量的时间以及结果的定义而异。到目前为止，可用的研究太少，无法克服几个潜在的异质性来源。
一般来说，不存在一套核心的病假预测因素。包括决定报告病假或重返工作岗位在内的研究特征决定了几个预测因素对CLBP患者病假的影响。需要进一步研究并使用一套核心测量方法和统一的定义来预测CLBP患者的病假和重返工作情况。
