Reporting of noise-induced hearing loss: perceptions of primary health care professionals

Abstract

Background Worldwide, workers' health is still a Public Health concern, given the high number of hazardous occupational activities, as well as workers affected by work-related diseases. Among these diseases, occupational Noise-Induced Hearing Loss-NIHL is considered the second commonest occupational disease, and in Brazil, its reporting is compulsory. However, occupational diseases are usually underreported, hindering the knowledge of their actual magnitude, and the elaboration of prevention-oriented public policies. Objective To analyze the perception and knowledge of Primary Health Care professionals in Curitiba-Parana State, Brazil, on the compulsory NIHL reporting. Methods quantitative and qualitative approach conducted in three steps: analysis of a series of NIHL case histories reported in the official database between 2007 and 2018; application of a questionnaire to Primary Health Care Network professionals; collective interview with Primary Health Care Network nurses, speech therapists and doctors. Results NIHL reporting evidenced 82 cases, 67 (81.7%) among males, age ranging 50-64 years, 10 (12.2%) had complete high school level, 27 (32.9%) were formally employed, and 12 (14.6%) worked in the processing industry. Regarding the result of the applied questionnaire among the Primary Health Care professionals, 48 (68.7%) stated that they were prepared to identify workers' health problems, to 33 (68.7%) professionals, guidance to reassure users' comprehensive care is more important than the compulsory reporting, 21 (43.7%) claimed that they were qualified to identify NIHL cases, and 25 (52.1%) did not report the cases. Difficulties in reporting NIHL cases are: not understanding their flow, being afraid of the legal implications, which may generate difficulties in requesting audiometric testing, not having the management support, etc. Conclusions Most health care professionals are knowledgeable on NIHL, but they do not report the suspected cases due to lack of guidance. Key messages Primary care health professionals does not consider occupational health as part of the service to be provided. Primary care services are not prepared to establish the relationship between the injury and the job.
