Classification of Illness

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe and...

科学领域:

精神病学是一个精神病学.
机器学习机器学习
医疗信息学医疗信息学

背景情况:

机器学习模型需要出色的概括性,以便在实践中实现.
一个精神分裂症 (SZ) 分类模型之前已经为日本人口开发并内部验证.
外部验证对于确保SZ分类器的稳定性和通用性至关重要.

研究的目的:

用独立的门诊数据对SZ分类器进行外部验证.
评估SZ分类器在精神分裂症,双相情感障碍和严重抑郁症患者的表现.

主要方法:

SZ分类器接受了在线调查数据的培训,包括人口统计,健康和社会并发症特征.
外部验证使用了一个独立的门诊样本集.
用敏感度和错误分类率来评估模型性能.

主要成果:

对于精神分裂症患者,SZ分类器实现了0.75的灵敏度.
错误分类率为双相情感障碍的59%,主要抑郁症的55%.
该模型表明,在准确的个人级别诊断方面存在挑战.

结论:

在临床实施之前,SZ分类器需要进行改进,以提高准确性和减少错误分类率.
对某些精神疾病的特异性较差表明了局限性.
在模型开发中包括各种精神疾病可能会提高未来的性能.
