ABSTRACT
@#Objective - （ ） To analyze the epidemiological characteristics of occupational noise induced deafness ONID （ ） diagnosed by Guangdong Province Hospital of Occupational Disease Prevention and Control GDHOD from 2016 to 2020 and - Methods the reasons non ONID diagnosis. The data of ONID patients diagnosed in GDHOD from 2016 to 2020 were collected “ from the Occupational Disease Report Card in the Occupational Disease and Occupational Health Information Monitoring ” “ ” - System subsystem of the China Disease Prevention and Control Information System . The data of non ONID subjects were ， collected from the occupational disease diagnosis archives in the same hospital and the relevant data were analyzed Results ， ， （ ） retrospectively. Of the 1 432 subjects 824 subjects were diagnosed as ONID patients mainly of mild ONID 86.0% . （M） ， M Male patients accounted for 88.0%. The median of diagnosis age was 45.0 years old and of length of employment of ， ， ， diagnosis was 8.3 years. ONID patients were mainly found in Zhongshan Dongguan Zhuhai Jiangmen and Guangzhou City in ， ， （ ） the Pearl River Delta accounting for 67.6%. The cases distributed in 519 enterprises mainly on manufacturing 90.2% . ， - ， ； Among the 139 enterprises each enterprise had 2 11 patients worked within five years accounting for 53.9% 91.1% of the -， - - - ONID patients were distributed in large medium and small enterprises. ONID patients mainly worked in non public enterprises that accounted for 91.3%. There were 606 subjects could not be diagnosed as ONID. The main reasons for not being （ ）， diagnosed were that the weighted value of better ear hearing threshold was less than 26 dB 34.8% the working history of （ ）， occupational noise exposure was less than three years 31.5% the weighted value of better ear hearing threshold was less thanConclusion 26 dB and the average hearing threshold of binaural high frequency was less than 40 dB 16.2% . The ONID ， ， -， - patients have the characteristics of group aggregation. The Pearl River Delta manufacturing industry large medium and - - ： small non public enterprises are the key points of ONID prevention. The main reasons for not being diagnosed as ONID were ， the working history of occupational noise exposure was less than three years the weighted value of better ear hearing threshold ， - was less than 26 dB and the average high frequency hearing threshold of both ears was less than 40 dB.
ABSTRACT
@#Improving the efficiency of occupational disease diagnosis and verification is conducive to protecting the rights and interests of workers, better realizing the legislative value pursuit of the Law of the People's Republic of China on the Prevention and Control of Occupational Diseases, and truly demonstrating the spirit of legal fairness and justice. In 2021, the Administration Measures for the Diagnosis and Verification of Occupational Disease was revised and implemented. The working procedures of occupational disease diagnosis are adjusted and optimized, and the efficiency of diagnosis of occupational disease is greatly improved. They include items such as new provisions specifying working time limits; optimize the working mode; the diagnosis of occupational disease attribution applies to presumptive causality is emphasized and the logical thinking of inversion of burden of proof is carried out. However, the work efficiency of occupational disease diagnosis does not make a great breakthrough in quality, mainly manifests in three aspects: difficult to confirm labor relationships, raising the threshold of occupational disease diagnosis, the administrative field investigation is empty and the diagnosis of occupational disease is complicated. There are many pre-procedures in occupational disease diagnosis, which restrict the efficiency of diagnosis. In the future, attention needs to be paid to promote the independent work of occupational disease diagnosis institutions, and through the revision of the Law of the People's Republic of China on the Prevention and Control of Occupational Diseases. Occupational disease diagnosis institutions should be empowered to confirm labor relationship, so as to lower the threshold of diagnosis of occupational disease and maximize the protection of the rights and interests of workers.
