概括

国际疾病分类 (ICD) 代码在识别功能性发作 (FS) 方面表现不一. 在本研究中,ICD-10代码F44.5显示出检测FS患者的最佳总体有效性.

科学领域:

神经学神经学
医疗信息学医疗信息学
诊断的准确性诊断的准确性

背景情况:

功能性发作 (FS) 难以诊断,通常需要与区分开来.
精确识别FS对于适当的患者管理和医疗保健资源分配至关重要.
国际疾病分类 (ICD) 代码用于识别FS的实用性尚未得到全面评估.

研究的目的:

评估特定ICD-9-CM和ICD-10代码的诊断有效性,用于识别具有功能性发作 (FS) 的患者.
为了比较不同ICD代码在检测假定的和可能/可能的FS病例中的性能.

主要方法:

在两个不同的时间段对800名患者进行图表审查 (2012-2013年为ICD-9-CM,2022-2023年为ICD-10).
对ICD-9-CM代码300.11和780.39以及ICD-10代码F44.5和R56.9.9的评估
在机构范围样本中计算正预测值 (PPV),在监测单位 (EMU) 样本中计算灵敏度,特异性,PPV和负预测值 (NPV).

主要成果:

在整个机构的样本中,ICD-10代码F44.5显示了最高的PPV (74.0-80.0%),在假定FS的EMU样本中表现强 (敏感度67.1%,特异性95.8%,PPV 91.7%,NPV 80.7%).
与F44.5.5.11相比,ICD-9-CM码300.11在EMU样本中具有较低的PPV (52.0-59.0%) 和较差的性能指标.
ICD代码R56.9和780.39显示PPV非常低 (<20%) 在两个样本中表现不佳.

结论:

ICD代码具有可变的准确性,用于识别有功能性发作的患者.
ICD-10代码F44.5是评估识别FS患者的代码中最有效的.
进一步完善编码实践可以改善功能神经系统疾病的识别和研究.

Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Arteries of the Lower Limbs

Arteries of the Lower Limbs

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
