Objective To establish a method to objectively evaluate the application of occupational health surveillancetechnical specification (GBZ 188-2007).
Methods A modified Delphi method was adopted to set up evaluation indexsystem and index weights.Then a questionnaire was developed according to the evaluation index system and sent to the principalsand main inspectors from centers for disease control and prevention,occupational disease prevention and treatment institutes,general hospitals,and other health care institutions in mainland China.Combining with the weight of each index,fuzzy scores wereobtained,and fuzzy comprehensive evaluation method was employed to grade the items in the specification thoroughly.
Results Seventeen experts participated in the two-round consultation about setting up the evaluation index system.The specialistauthoritative coefficient was 0.904,and the coordination coefficient of all indicators was 0.469(P<0.01).The assessment indexsystem consisted of 3 first-rank indicators and 14 second-rank indicators which were further divided into 70 third-rank indicators,covering implementation,application performance,and scientific connotation.A total of 114 respondents took part in thequestionnaire survey,and the responding rate was 100%.In the fuzzy comprehensive evaluation,the proportions of "excellent","moderate",and "bad" indicators were 80.8%,14.7%,and 4.5%,respectively.The proportions of "excellent" indicators of the 3 first-rank indicators were 78.4%,75.1%,and 83.0% respectively.
Conclusion The combination of modified Delphi methodand fuzzy comprehensive evaluation provides an effective solution for the assessment of the specification application.However,theprotocol should be further validated.
