Abstract:
Objective To establish an evaluation system for the field assessment of the Kato-Katz technique in detecting soiltransmitted nematodes, so as to provide insights into the field application of the Kato-Katz technique. Methods The initial evaluation indicators were determined through literature search, brainstorming and expert consultation. The evaluation indicatorswere improved and the weight of each indicator was decided through three rounds of expert consultation by using the Delphimethod. In addition, the expert authority coefficient and the coordination coefficient of each indicator were calculated at eachround of expert consultations. Results The recovery rates of the questionnaire were 100.00%, 100.00% and 89.29% at the firstto the third round of the expert consultations, respectively, and the expert authority coefficients were all more than 0.85 at eachround. The final evaluation system included 4 first-level indicators and 15 second-level indicators. In the first-level indicators, “detecting effect” and “funds investment” had the mean weighted value of 4.53 and 4.49, which were relatively higher than that of“person-time investment“ and "operability“ (both 4.34). Among the second-level indicators under each first-level indicator, thefour most significant indicators included “ability of personnel in egg discrimination“, “cooperation of village cadres and doctors“,“Person-time on testing“ and “organizational start-up cost“, with the mean weighted values of 4.74, 4.43, 4.39 and 4.17, respectively. The coordination coefficients were 0.39 to 0.65, 0.28 to 0.58 and 0.45 to 0.65 at the first to the third round of the expertconsultations, respectively, and there were significant differences in the coordination coefficients at all three rounds of the consultations (all P < 0.05). Conclusions An evaluation system for the field assessment of the Kato-Katz technique in detecting soiltransmitted nematodes is successfully established, among which “ability of personnel in egg discrimination“ and “cooperation ofvillage cadres and doctors“ have the greatest mean weighted values of the significance.
