Abstract:
Objective:To learn about the diagnosis of Kala-azar in Gansu Province, and to provide a basis for formulating corresponding prevention and control measures.Methods:The data (age, gender, onset time, diagnosis time, diagnosis unit, etc.) of Kala-azar cases in Gansu Province from January to December 2018 were collected from the China Disease Prevention and Control Information System. At the same time, a case report questionnaire was designed to collect information such as the initial diagnosis unit and initial diagnosis results; a diagnosis and treatment questionnaire of medical institutions was designed to investigate the knowledge of diagnosis and treatment of Kala-azar (main epidemic areas, main symptoms, common detection methods, main therapeutic drugs and drug use methods) among doctors in county and township hospitals, and the pass rate and awareness rate were calculated.Results:A total of 47 Kala-azar cases were included, with an average age of 17 years. Among them, men accounted for 57.45% (27/47) and women accounted for 42.55% (20/47). Among the initial diagnosis hospitals, the proportions of provincial, municipal, county and township hospitals were 2.13% (1/47), 12.77% (6/47), 42.55% (20/47) and 42.55% (20/47), respectively; among the hospitals with confirmed cases, provincial, municipal, county and township hospitals accounted for 48.94% (23/47), 31.91% (15/47), 19.15% (9/47) and 0 (0/47), respectively. The shortest time from initial diagnosis to diagnosis of the 47 cases was 1 day; the longest was 124 days, with an average of 27 days. A total of 96 valid questionnaires were collected from doctors in county and township hospitals, of which 30 scored 60 points or above, and the pass rate was 31.25% (30/96). Among the five surveys on diagnosis and treatment knowledge of Kala-azar, doctors in county and township hospitals had the highest awareness rate of "main therapeutic drugs", which was 77.08% (74/96), and there was significant difference (χ 2 = 9.86, P = 0.002) between doctors in the two-level hospitals [90.00% (45/50), 63.04% (29/46)]. The awareness rate of "main symptoms" was the lowest, which was 25.00% (24/96), and there was significant difference (χ 2 = 4.51, P = 0.034) between doctors in the two-level hospitals [34.00% (17/50), 15.22% (7/46)]. Conclusions:The awareness rate of diagnosis and treatment knowledge of Kala-azar among doctors in county and township hospitals in Gansu Province is low, and their diagnostic ability is weak. It is recommended to strengthen the training of clinicians, improve the timeliness of diagnosis, and achieve early diagnosis, early report and early treatment of Kala-azar.
