Analysis on medical treatment and diagnosis of imported malaria in Anhui, 2016-2019

Objective To analyze the medical treatment and diagnosis of imported malaria cases in Anhui Province, and we provide a basis for the development of technical measures to block the retransmission of imported malaria after the elimination of malaria. Methods Data on imported malaria cases in Anhui Province from 2016 to 2019 were collected through the National Infectious Diseases Information Reporting Management System (IDIRMS) and the Parasitic Diseases Information Reporting Management System (PDIRMS). The medical institution, diagnosis institutions and diagnosis timeliness of imported malaria cases were described and analyzed by chi-square test and rank-sum test. Results A total of 421 cases of imported malaria were reported in Anhui Province from 2016 to 2019, including four species of malaria, and 3 deaths. 86.5% (364/421) of the cases first visited in medical institutions, and 70.1% (295/421) of the cases were correctly diagnosed as malaria at the first visit. The correct diagnosed rate of initial visit by CDCs (100.0%) was higher than that of medical institutions (66.8%)( P 0.05); the difference in the ratio of the number of days between the first visit and the diagnosis between the years was statistically significant ( P 0.05), however, the initial diagnosis-diagnosis time of severe falciparum malaria cases [3 (1, 5)] was longer than that of mild cases [1 (1, 3)], and the difference was statistically significant ( P 0.05);各年份初诊-确诊时间间隔天数构成比差异有统计学意义( P 0.05),重症和轻症恶性疟病例初诊-确诊时间中位数( P 25 , P 75 )分别为3(1,5) d和1(1,3) d,差异有统 计学意义( P <0.05)。3例死亡病例在初诊时未被确诊,于发病后≥3 d确诊。 结论 安徽省输人性病例的初诊和确诊单 位主要在医疗机构,尤其是县级以上医疗机构,需继续提高医疗机构的疟疾诊断水平,并减少重症病例的发生,同时加 强健康教育以提高病例及时就诊意识。
