摘要
涂阳患病发病比值（Ｐ／Ｉ值）是结核病控制工作的一项评价监测指标，以年终统计时点涂阳登记病人数和年内涂阳新登记病人数的比值表示，其内涵被认为系某地区涂阳病人平均登记期。随着化疗进展，特别是短程化疗日益普及，以及涂阳登记标准的改变，对该比值内涵应给予新的认识。本文着重从比值的定义和计算公式方面进行讨论。由于涂阳登记统计标准的改变，使比值发生了量变和质变，特别是短程化疗的广泛应用，更增加这种变化的程度。由此，提出“涂阳患病发病比值是表示某地区涂阳病人登记治疗后的平均痰菌阳性期（排菌期）”的新认识，并讨论了这一新内涵的实用意义。
The ratio of smear positive prevalence to incidence(P/I value) is one of the indices to evaluate and surveillant TB control.It is indicated by the ratio of numbers of registered smear positive case at the end of one year to numbers of new registered smear positive case during the year.It's connotations have been known as the average interval of smear positive cases in a certain district.The connotations of the ratio would be given new recognizations along with the progress,of chemotherapy,in particular,the increasingly popularized of short-course chemotherapy and the change of the criteria of registered smear positive cases.In this thesis,it was emphatically disecussed that the changes of registration statistics standard of smear positive make the ratio changed in quantity and quality from its definition and calculative formula.Particularlly,the extensive adoption of short-coure chemotherapy makes such a increasing change,It is a new knowledge raised in this thesis-'the ratio of smear positive prevalence to incidence indicates the average sputum positive period(the period of secretion bacteria)of smar positive cases after being registered and treated in a certain region'.The practical value of the new knowledge was also discussed in this thesis.
