Indicators | Variables calculated | Formula/narration |
---|---|---|
Past prevalence | Prevalence calculated by the site data of the Past quality. District level calculation: It is the average prevalence of all site prevalence of the most recent year and the Past diagnostic methods Subdistrict level: It is the highest |
Site prevalence: the site prevalence if not already calculated is calculated as below: -Number of people positives/Number of people examined *100 District Prevalence (DP): - (Total positives) / (Total examined) * 100 |
prevalence of all site prevalence of the most recent year and the Past diagnostic methods | Prevalence of the subdistrict (SDP): Highest site prevalence among all sites (in the highest quality group) in the communities-based on parasitological technique/results | |
Year of Past prevalence | Year of the Past prevalence of the district or communities | |
Diagnostic methods of the Past prevalence | Diagnostic methods of the Past prevalence of the district or communities | For calculation of prevalence, the following diagnostic tests results were used: - Kato Katz technique, Urine filtration technique, Urine sedimentation technique, blood in urine (BIU), dipstick and point-of-care circulating cathodic antigen test |
Number of sites of the Past prevalence | Number of sites used for the calculation of the Past prevalence of the district or communities | Based on the parasitological or clinical laboratory methods |
Endemicity by the Past prevalence | Endemicity category determined by the Past prevalence of the communities or district (The endemicity category is determined as recommended in the WHO guidelines | Non-endemic, Low prevalence (<10 %), Moderate prevalence (10 %–49 %) High prevalence (50 % and above) |
School Aged Children (SAC) needing preventive chemotherapy (PC) | Total number of school age children living in an endemic area classified low, moderate, or high risk | Low prevalence (<10 %), Moderate prevalence (10 %–49 %) High prevalence (50 % and above) |
Adult needing PC | Number of adults needing treatment in an endemic area classified moderate, or high risk | Low risk: no adult treatment is recommended Moderate risk: 20 % of the total adult population in the sub district or district High risk: All he adult population in the sub district or district |
Drug estimates | The number of drugs needed is calculated by multiplying the population to be treated by a factor that depends on the age. This factor is 2.5 for school age children and 3 for adults | The dose by treatment is 2.5 tablets per SAC and 3 tablets per adult. |
Treatment adequacy | Comparison of preventive Chemotherapy (PC) regimen at district level compared to sub district level | No change in strategy: the treatment strategy does not change from district implementation to community's implementation Adequate: No change in preventive chemotherapy (PC) regimen Under treatment: PC regimen at district level is lower than PC regimen suggested by communities' analysis. Over treatment: PC regimen at district level is higher than PC regimen suggested by communities' analysis |
