概括
研究人员应在数据库研究中使用国际疾病分类 (ICD) 代码来定义结椎炎 (AS) 时使用更高的正预测值 (PPV) 算法,以避免错误分类偏差. 这项验证研究发现PPV在72.77%至85.64%之间.
科学领域:
- 类风湿病学 类风湿病学
- 医疗信息学 医疗信息学
- 流行病学 流行病学
背景情况:
- 使用国际疾病分类 (ICD) 代码的基于索赔的算法经常用于在研究中识别性脊柱炎 (AS).
- 这些基于索赔的算法存在潜在的错误分类偏差,需要验证它们在代表AS诊断中的准确性.
研究的目的:
- 验证现有的基于索赔的算法在诊断结性脊髓炎 (AS) 中的准确性.
- 评估不同国际疾病分类 (ICD) 代码算法用于AS识别的积极预测值 (PPV).
主要方法:
- 从台湾医疗中心的电子健康记录中获取了ICD编码的AS诊断的患者.
- 随机抽样并按年龄和性别分层患者.
- 根据2009年ASAS指南评估医疗信息,并为各种ICD代码算法计算PPV.
主要成果:
- 包括从4160名初始队列中的387名基于索赔的AS诊断的患者.
- 需要至少4个门诊或1个住院ICD记录的算法的PPV为72.77%.
- 将诊断限制在风湿病学家的诊断上,使PPV增加到85.64%.
结论:
- 在数据库研究中,研究人员必须在定义结脊柱炎 (AS) 时承认不同算法的可变正预测值 (PPV).
- 建议使用具有较高PPV的算法来缓解错误分类偏差并提高研究准确性.
- 诊断算法的验证对于在风湿病学中进行可靠的流行病学研究至关重要.

Autoimmune Disorders
439
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Genome-wide Association Studies-GWAS
13.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
