Qualitative analysis of the model suggests that maintaining low levels extremely close to zero or exactly zero percentage for leprosy relapse cases, coupled with a high level of case finding of non-symptomatic leprosy carriers together with high level of treatment compliance, may have a substantial effect on controlling a leprosy epidemic.
At its best, the study suggests that high level of case finding targeting non-symptomatic and symptomatic individuals, together with high level of compliance by individuals on treatment, may have a substantial effect on controlling leprosy relapses and possible may assist on attaining leprosy eradication.
This study has a high level of case ascertainment and diagnostic confirmation.
The Birth Defects Registry in Western Australia has a high level of case ascertainment (Bower et al. 2000, 2001).
By contacting the specific region that does not refer all cases to the CPHL, a high level of case capturing is ensured.
The use of several different sources of data to identify incident cases of ALL in a relatively small geographic region, where few centres treat this condition will have resulted in a very high level of case ascertainment.
Despite the large number of cases analyzed from cancer registries that have a high level of case ascertainment, consistency and representativeness, a lack of power cannot be excluded for the less frequent cancer sites.
The national French registry of childhood haematopoietic malignancies, with a high level of case ascertainment, constitutes a reliable data set, which enables, among others, to carry out spatial and space time analyses over the whole territory.
Incident cases of oral cancers (ICD-10 C00-C06) and cancers of the oro-pharynx (C09, C10, and C14) for the period 1976 2002 were obtained from the Scottish Cancer Registry, which has a high level of case ascertainment (Brewster et al, 1997) and accuracy of postcodes, from which the Carstairs scores were derived (see below) (Brewster et al, 2002).
To achieve the current goal of a high level of case detection (75%) and cure (85%) by the year 2015, a finer study of the epidemiological characteristics of TB patients to pinpoint risk factors involved and access to health care is needed in different regions of the world [ 2].
