title: Evaluation of a multidrug therapy programme of leprosy control.
abstract: MDT programmes for leprosy control have two objectives, controlling leprosy in populations and controlling leprosy in individuals. Evaluation of such programmes needs to address both objectives and this can be done by a review of the trends in key indicators and by site visits. Site visits are more expensive and should be done less frequently, but they can reveal issues not apparent in routinely produced statistics. Evaluation on an annual basis is the responsibility of programme managers and programme funders. Evaluation by programme staff themselves should be encouraged and supported. Evaluation of an MDT programme's effectiveness in controlling leprosy in a population should be by analysis of case detection as a proxy for incidence. Prevalence rates will continue to be monitored because of the WHO elimination goal, but these do not reflect disease transmission. Case detection is a proxy measure of incidence and depends on consistency in case detection activities. Case detection data by age, gender, mode of detection, disability ratio and lepromatous (MB) rate need to be analysed over at least 5 years and preferably 10 years to give an indication of trends in incidence. Caution is needed, however, as the pattern seen when case detection deteriorates may resemble the pattern expected when transmission is reduced. The site visit is important in this situation in allowing examination of the case detection activities, as well as in looking for new, undetected cases in the population.(ABSTRACT TRUNCATED AT 250 WORDS)
