世界卫生组织的结核病 (TB) 控制目标是发现 70% 的新涂片阳性结核病病例并治愈其中 85% 的病例。病例检出率是每年每 10 万人报告的病例数除以每年每 10 万人的估计发病率。结核病发病率不确定，不是测量而是估计；因此，病例检出率是不确定的。本文提出了一个评估病例发现的新指标：患者诊断率。患者诊断率是通过控制计划检测到流行病例的比率，可以用每年每 100,000 人报告的病例数除以每 100,000 人的流行率来衡量。患病率可以通过国家患病率调查直接衡量。每 5 至 10 年进行一次患病率调查将使疾病发病率高的国家能够利用患者诊断率来确定其病例检测表现，并确定控制措施的效果。
The World Health Organization's goal for tuberculosis (TB) control is to detect 70% of new, smear-positive TB cases and cure 85% of these cases. The case detection rate is the number of reported cases per 100,000 persons per year divided by the estimated incidence rate per 100,000 per year. TB incidence is uncertain and not measured but estimated; therefore, the case detection rate is uncertain. This article proposes a new indicator to assess case detection: the patient diagnostic rate. The patient diagnostic rate is the rate at which prevalent cases are detected by control programs and can be measured as the number of reported cases per 100,000 persons per year divided by the prevalence per 100,000. Prevalence can be measured directly through national prevalence surveys. Conducting prevalence surveys at 5- to 10-year intervals would allow countries with high rates of disease to determine their case detection performance by using the patient diagnostic rate and determine the effect of control measures.
