Table 1 Evaluation criteria for alternative sets of adjusted malaria incidence estimates

From: Estimating the local spatio‐temporal distribution of malaria from routine health information systems in areas of low health care access and reporting

Criteria Description Evaluation method
(a) Overall malaria incidence Overall adjusted malaria incidence for Ifanadiana should be similar to overall malaria incidence in populations with optimal health care access in the district, to avoid under- or overestimation Ratio of adjusted malaria estimates to malaria in optimal access areas between 0.7 and 1.3
(b) Distance decay Adjusted malaria incidence estimates should remove the distance decay observed in unadjusted malaria incidence, to limit bias due to geographic access to health care Ratio of incidence less than 5 km from a health center to incidence greater than 5 km away 0.7–1.3
(c) Financial access Differences in adjusted malaria incidence between health centers according to fee-exemption status should be minimal, to limit bias due to financial access to health care Ratio of fee-exemption to no fee-exemption in adjusted malaria estimates between 0.7 and 1.3
((d) Geographic heterogeneity The geographic distribution of adjusted malaria incidence should be similar to the geographic distribution of fever reported in the IHOPE cohort study during the high transmission season Percent of hotspot cluster area overlap between the two datasets during high malaria transmission season (SaTScan)
