[Establishment of index system of key factors on elimination of schistosomiasis]
Objective:
To establish an index system of the key factors of elimination of schistosomiasis.
Methods:
A questionnaire was designed based on the reference review, and 24 scientists working in the field of schistosomiasis control or research or management were investigated by using the Delphi method. The importance of each index reflecting the endemicity of schistosomiasis wis scored by each scientist. The assessing system for key factors of eliminating schistosomiasis was established, and the normalized weight and combined weight were calculated.
Results:
The assessing system included three indexes in the first grade, seven indexes in the second grade and thirteen indexes in the third grade. Among the indexes in the first grade, the normalized weights of endemicity, natural environment and social environment were 0.371 1, 0.339 5, and 0.289 4, respectively. Among the indexes in the second grade, the economy showed the highest combined weight of 0.289 4 while the agriculture and sanitation both showed the lowest score of 0.112 7. Among the indexes in the third grade, the infection rate of animals showed the highest combined weight of 0.124 6 while the agriculture and plant structure both showed the lowest score of 0.053 0.
Conclusion:
The indexes of the assessing system provide the scientific evidence for surveillance work when elirnination of schistosomiasis.
