Employees and self-employed persons have, among others, different personal characteristics and different working conditions, which may influence the prognosis of sick leave and the duration of a disability claim. The purpose of the current study is to identify prognostic factors for the duration of a disability claim due to non-specific musculoskeletal disorders (MSD) among self-employed persons in the Netherlands.
The study population consisted of 276 self-employed persons, who all had a disability claim episode due to MSD with at least 75% work disability. The study was a cohort study with a follow-up period of 12 months. At baseline, participants filled in a questionnaire with possible individual, work-related and disease-related prognostic factors.
The following prognostic factors significantly increased claim duration: age > 40 years (Hazard Ratio 0.54), no similar symptoms in the past (HR 0.46), having long-lasting symptoms of more than six months (HR 0.60), self-predicted return to work within more than one month or never (HR 0.24) and job dissatisfaction (HR 0.54).
The prognostic factors we found indicate that for self-employed persons, the duration of a disability claim not only depends on the (history of) impairment of the insured, but also on age, self-predicted return to work and job satisfaction.
员工和自雇人士除其他外，具有不同的个人特征和不同的工作条件，这可能会影响病假的预后和残疾索赔的持续时间。本研究的目的是确定荷兰自雇人士非特异性肌肉骨骼疾病（MSD）导致残疾索赔持续时间的预后因素。
研究人群包括 276 名自雇人士，他们都因 MSD 导致残疾索赔，至少有 75%的工作能力丧失。这是一项队列研究，随访期为 12 个月。在基线时，参与者填写了一份问卷，其中包含可能的个体、与工作相关和与疾病相关的预后因素。
以下预后因素显著增加了索赔持续时间：年龄>40 岁（风险比 0.54）、过去无类似症状（HR 0.46）、症状持续时间超过六个月（HR 0.60）、自我预测在一个月以上或从未恢复工作（HR 0.24）和工作不满（HR 0.54）。
我们发现的预后因素表明，对于自雇人士而言，残疾索赔的持续时间不仅取决于受保人的（既往）损伤程度，还取决于年龄、自我预测的工作恢复时间和工作满意度。
