Objective To make an attempt in introducing the categorization and quantified classification administration mode in occupational health supervision into Shanghai municipal occupational health supervising, and to analyze as well as to examine its effectivity.
Methods Indices for categorization and quantified classification were developed pursuant to Law of the Peoples Republic of China on Prevention and Control of Occupational Diseases and Measures of Shanghai Municipality on the Administration over Categorization and Quantified Classification in Occupational Health Supervision, together based on the database of daily supervision and administration, and experts' professional judgments. The foregoing indices were applied to categorize and classify the 12932 enterprises existing occupational diseases hazard in Shanghai and then primary examination was made.
Results Among the classified enterprises, 10 274 were classified as the existing ordinary occupational diseases hazard, accounting for 79.4% of the total, while 2 658 classified as existing severe occupational diseases hazard, accounting for 20.6%. Using grade A, B and C of occupational health grading system to respectively indicate their conditions as good, median and bad, the enterprises graded as B accounted for 61.3% of all those classified as existing ordinary occupational diseases hazard while 53.5% of those classified as existing severe hazard, presenting a ‘spindle-shaped’ mode with ‘big in the middle and small at the two ends’. However, the total number of the enterprises graded as A plus B accounted for over 80% of either classification (existing ordinary or severe occupational diseases hazard).
Conclusion The categorization and quantified classification method is an important tool not only for establishing the long-term effective mechanism for occupational health supervision, but also in realizing the transition in administration mode from static and qualitative administration to dynamic, qualitative and quantitative administration.
