Increasing numbers of tuberculosis control programs compile information about the number, location, bacteriologic status, and chemotherapy status of tuberculosis patients within their jurisdiction. Reports from these programs show that during the 1970s the prevalence of patients requiring supervision decreased three times faster than the incidence of tuberculosis; this decline occurred because low relapse rates among patients who had received adequate therapy allowed the recommended duration of follow-up after completion of therapy to diminish from lifetime to none. The prevalence of patients hospitalized for tuberculosis decreased four times faster than the incidence of tuberculosis because the duration of hospitalization decreased from many months to a few weeks and because a small proportion of patients were hospitalized. Future declines in these two program aspects are expected to be much smaller and should parallel the decline in morbidity more closely. Other measures of program performance have shown a less favorable trend and suggest an impeded flow of information to the health department from other persons or agencies involved in the care of tuberculosis.
越来越多的结核病控制项目开始收集其管辖范围内结核病患者的数量、地点、细菌学状况和化疗情况等信息。这些项目的报告显示，在20世纪70年代，需要监管的患者患病率下降速度比结核病发病率快三倍；这种下降的发生是因为接受充分治疗的患者复发率较低，使得治疗完成后推荐的随访时间从终身缩短至无需随访。因结核病住院的患者患病率下降速度比结核病发病率快四倍，这是因为住院时间从数月缩短至几周，且住院患者比例较小。预计这两个项目指标未来的下降幅度将小得多，且应更紧密地与发病率的下降同步。项目绩效的其他衡量指标显示出不太乐观的趋势，表明参与结核病护理的其他人员或机构向卫生部门传递信息存在障碍。
