To shed light on several epidemiological terms for better understanding of diagnostic testing measures by using a mythical condition, "purple mange."
Scientific literature related to epidemiology and statistical tests.
Nurse practitioners (NPs) use the concepts of sensitivity (SEN), specificity (SPEC), positive predictive value (PPV), and negative predictive value (NPV) daily in primary care and specialty areas. In addition, PPV and NPV vary with the prevalence of a condition. At times, NPs misunderstand the meaning of these terms.
In order to develop appropriate treatment plans, an understanding of the concepts of SEN, SPEC, PPV, and NPV is important for interpreting test results. The authors have used this mythical condition purple mange as a teaching tool for NP students.
通过使用一种虚构的病症“紫色疥癣”来阐明几个流行病学术语，以便更好地理解诊断检测措施。
与流行病学和统计检验相关的科学文献。
执业护士（NPs）在初级保健和专科领域每天都会使用敏感度（SEN）、特异度（SPEC）、阳性预测值（PPV）和阴性预测值（NPV）的概念。此外，PPV和NPV会因病症的患病率而有所不同。有时，NPs会误解这些术语的含义。
为了制定合适的治疗方案，理解SEN、SPEC、PPV和NPV的概念对于解释检测结果很重要。作者将这种虚构的病症紫色疥癣用作NP学生的教学工具。
