Summary of Epidemiological Study:
Title: Factors associated with severe malaria and delayed healthcare seeking behavior in Kabarole District, 2017-2018

Introduction: Death due to malaria-related causes among children can go as high as thirty per cent. These deaths can be avoided as progression of malaria to its severe forms is preventable. Kabarole District is one of districts that have reported high rates of malaria-related deaths. We investigated to find out the magnitude of severe malaria, assess associated risk and evaluate factors associated with delayed healthcare seeking among patients attending Bukuuku Health Center IV.
Methods: We defined severe malaria according to the WHO criteria. We identified our cases from Bukuuku Health Center IV from 1 January 2017 to May 2018. We then described cases by person, place, time and clinical characteristics. We conducted a case-control study to evaluate association between risk factors and severe malaria. We randomly selected controls from uncomplicated malaria patients who attended the same facility during the same period as cases. Controls were matched by age group and village of residence in a ratio of 1:1. In a subgroup analysis, we identified factors associated with delayed healthcare seeking.
Results: We identified 115 severe malaria cases from January 2017 to May 2018. This constituted 8.6% of all malaria cases in the facility. Children <5 years old were more affected, with an attack rate of 21/1,000 (50/2,335) compared with 5.7/1,000 (65/11,395). Compared to males with an attack rate of 7.9/1,000 (53/6,350), females were more affected (AR: 8.9, 62/6980). Karago and Kazingo parishes were the most affected with attack rates >4.0/1,000. The highest number of cases was observed in May and December, 2017. We found that seeking care beyond 24 hours of developing symptoms of malaria (aOR=15, 95%CI: 3.0-77) was associated with severe malaria. We also found that getting the first treatment from a drug shop (aOR=16, 95%CI: 5.3-47) and from home (aOR=26, 95%CI: 4.1-163) were associated with delayed healthcare seeking.
Conclusion and Recommendations: The proportion of severe malaria relative to the total number of malaria cases is high. Severe malaria in the district is associated with delayed health care seeking, which is further associated by receiving first treatment either from a nearby drug-shop or home.
