Practical Implications of a Relationship between Health Management Information System and Community Cohort-Based Malaria Incidence Rates. Am J Trop Med Hyg. 2020 Apr 06;: Authors: Kigozi SP, Giorgi E, Mpimbaza A, Kigozi RN, Bousema T, Arinaitwe E, Nankabirwa JI, Sebuguzi CM, Kamya MR, Staedke SG, Dorsey G, Pullan RL Abstract Global malaria burden is reducing with effective control interventions, and surveillance is vital to maintain progress. Health management information system (HMIS) data provide a powerful surveillance tool; however, its estimates of burden need to be better understood for effectiveness. We aimed to investigate the relationship between HMIS and cohort incidence rates and identify sources of bias in HMIS-based incidence. Malaria incidence was estimated using HMIS data from 15 health facilities in three subcounties in Uganda. This was compared with a gold standard of representative cohort studies conducted in children aged 0.5 to < 11 years, followed concurrently in these sites. Between October 2011 and September 2014, 153,079 children were captured through HMISs and 995 followed up through enhanced community cohorts in Walukuba, Kihihi, and Nagongera subcounties. Although HMISs substantially underestimated malaria incidence in all sites compared with data from the cohort studies, there was a strong linear relationship between these rates in the lower transmission settings (Walukuba and Kihihi), but not the lowes...
