Objective: 

To evaluate the baseline level and demographic predictors of statistical literacy in orthopaedic patients who sustained traumatic injuries.

Design: 

Prospective observational.

Setting: 

Level 1 trauma center.

Patients: 

One hundred ninety-eight patients presenting to the orthopaedic trauma clinic.

Intervention: 

Berlin Numeracy Test (BNT) and General Health Numeracy Test-6 (GHNT-6).

Results: 

When assessed using the BNT, 67% of patients had results that placed them into the lowest quartile of objective numeracy skills. Only 3.5% of patients had results that scored in the top quartile. Our multivariate ordinal regression model demonstrated lower education level (P = 0.01), and older age (P = 0.03) were significant predictors of poor performance on the BNT. The mean score on the GHNT-6 was 36% (SD 30%).

Conclusions: 

In a cohort of traumatically injured patients, poor statistical literacy was common, occurring in more than two-thirds of patient surveyed. Older age and lower levels of education were predictive of poor BNT performance and should be considered when discussing surgical options, associated risks, and likelihood of potential complications.

骨科创伤人群的统计素养

客观的： 

评估遭受外伤的骨科患者的统计素养的基线水平和人口统计学预测因素。

设计： 

前瞻性观察。

环境： 

一级创伤中心。

患者： 

一百九十八名患者在骨科创伤诊所就诊。

干涉： 

柏林算术测试 (BNT) 和一般健康算术测试 6 (GHNT-6)。

结果： 

当使用 BNT 进行评估时，67% 的患者的结果将他们置于客观算术技能的最低四分位数。只有 3.5% 的患者的结果得分在前四分之一。我们的多元序数回归模型表明较低的教育水平（P = 0.01）和年龄较大（P = 0.03）是 BNT 表现不佳的重要预测因素。GHNT-6 的平均得分为 36% (SD 30%)。

结论： 

在一组受外伤的患者中，统计知识较差的情况很常见，超过三分之二的接受调查的患者出现这种情况。年龄较大和教育水平较低可预测 BNT 表现不佳，在讨论手术选择、相关风险和潜在并发症的可能性时应予以考虑。
