To assess the validity of the Back Disability Risk Questionnaire (BDRQ) to predict developing chronic back disability.
Five hundred nineteen working adults (67% male) seeking outpatient care for acute, work-related back pain (<or=14 days) completed the BDRQ. After the initial medical evaluation, clinicians provided prognostic impressions in a 10-item questionnaire. Pain, functional limitation, and work status were assessed at 3-month follow-up.
In multivariate analyses, the presence of persistent pain, functional limitation, or impaired work status (31.4%) was predicted by six BDRQ questions: injury type, work absence preceding medical evaluation, job tenure, prior back surgery, worries about re-injury, expectation for early return-to-work, and stress. Classification accuracy at 3 months was 76.3%. Initial clinician impressions showed no multivariate associations with outcomes.
The BDRQ may provide prognostic information not observed in a routine medical evaluation for acute BP.
评估背部残疾风险问卷（BDRQ）预测慢性背部残疾发生的有效性。
519名因急性、与工作相关的背痛（≤14天）寻求门诊治疗的在职成年人（67%为男性）完成了BDRQ。在初步医学评估后，临床医生在一份10项问卷中提供了预后印象。在3个月随访时评估疼痛、功能受限和工作状态。
在多变量分析中，六个BDRQ问题可预测持续性疼痛、功能受限或工作状态受损（31.4%）的存在：损伤类型、医学评估前的工作缺勤、工作年限、既往背部手术、对再次受伤的担忧、早期重返工作岗位的期望以及压力。3个月时的分类准确率为76.3%。最初临床医生的印象显示与结果无多变量关联。
BDRQ可能提供在急性背痛的常规医学评估中未观察到的预后信息。
