Percepção de equipes de trabalho sobre o ruído em pronto-socorro / Perception of work teams about the noise at emergency room

RESUMO Objetivo Comparar a percepção dos profissionais das áreas de enfermagem e administrativa frente ao ruído no pronto-socorro. Métodos Estudo descritivo, com análise quantitativa. A percepção do ruído foi avaliada por meio de questionário, em forma de entrevista. Participaram do estudo 59 profissionais, 38 da área de enfermagem e 21 da área administrativa. O levantamento estatístico levou em conta o nível de significância de 0,05 (5%), através do teste Qui-quadrado. Resultados A percepção do ruído pelos profissionais de enfermagem e administração, no pronto-socorro, foi considerada como ruidosa e mais intensa no turno da tarde. Profissionais da enfermagem identificaram mais os ruídos dos equipamentos (60,53%) e os da área administrativa, os ruídos de pessoas (85,71%). As queixas extra-auditivas mais citadas foram cansaço, estresse, ansiedade, nervosismo e irritabilidade. Os profissionais da enfermagem demonstraram ser os mais incomodados com o ruído, porém, os administrativos referiram dificuldades em desempenhar suas tarefas. Conclusão Houve diferença na percepção do ruído entre os profissionais das áreas de enfermagem e administrativa, mas para ambas as áreas, o ruído de maior incômodo é aquele produzido por pessoas, mostrando a necessidade de programas educativos de prevenção e conscientização para redução de ruído, direcionados aos profissionais do pronto-socorro.

ABSTRACT Purpose Compare the perception of professionals in the nursing and administrative areas regarding noise in the emergency room. Methods Descriptive study with quantitative analysis. The noise perception was evaluated by means of an Adapted Questionnaire, in the form of an interview. A total of 59 professionals participated in the study, 38 from the nursing area and 21 from the administrative area. The statistical survey considered the level of significance of 0.05 (5%), through Chi-square test. Results The perception of noise by emergency room nursing and administration staff was considered noisy and most intense in the afternoon shift. Nursing professionals identified more the equipment noise (60.53%) and administrative workers the people noise (85.71%). The most frequently extra-auditory complaints were fatigue, stress, anxiety, nervousness and irritability. Nursing professionals are the most annoyed by noise, but administrative employees report more difficulties in performing their tasks in the face of noise. Conclusion There was a difference between perception of nursing and administrative area, but for both the most annoying noise is people. Implement educational prevention and awareness programs to reduce noise aimed at Emergency Room professionals.

Ambient noise in emergency rooms and its health hazards

Introduction The occupational risk due to high levels of noise in the hospital environment has been recognized, and the National Agency of Sanitary Surveillance of the Ministry of Health recommends evaluation and control of noise in hospital areas. Objectives To assess the sound environment in the emergency ward of a general trauma reference hospital in the city of Curitiba, Parana State, Brazil. Methods In this descriptive study, noise levels were assessed on mornings, afternoons, and evenings using an integrating Bruel & Kjaer (Denmark) calibrated sound levelmeter, type 2230. Ten indoor points in the emergency ward were assessed; the helicopter as well as several available pieces of equipment in the ward were assessed individually. Results Noise levels in sound pressure level ambiance [dBA] ranged from 56.6 to 68.8. The afternoon period was the noisiest. The helicopter at 119 dBA and the cast saw at 90 dBA were the noisiest equipment, and the lowest noise level found was the activated oximeter at 61.0 dBA. Conclusion In all assessed points, noise levels were above the comfort levels recommended by the Brazilian Association of Technical Standards (1987), which may harm users' and professionals' health as well as influence professional performance in the emergency ward. Sound pressure levels of the helicopter and cast saw reach high hearing hazard levels, requiring professionals to use individual protection equipment, and point to the need for creation and implementation of effective control measures of noise levels in emergency wards.

Ruído e seus impactos nos hospitais brasileiros: uma revisão de literatura / Noise and its impact on brazilian hospitals: a literature review

O aumento dos níveis de ruído nos hospitais, atribuído a diferentes fatores, dentre eles a grande incorporação de tecnologias, a concentração e o fluxo de pessoas e a não observância do silêncio pela própria equipe de trabalho e usuários do serviço, pode impactar negativamente no processo de trabalho e na saúde de profissionais e usuários. Este estudo teve como objetivo realizar revisão de literatura nacional sobre ruído em serviços hospitalares no Brasil, analisando aspectos referentes à produção científica, aos métodos de mensuração, aos níveis de ruído presentes nos hospitais, e às conclusões e estratégias propostas nos estudos analisados. O nível de ruído nos hospitais brasileiros está acima dos padrões recomendados acarretando impactos nesses serviços. Existe um relativo acúmulo de conhecimento sobre o tema no Brasil. Para ampliação desse conhecimento foram recomendados estudos de intervenção para mitigação do excesso de ruídos nos hospitalais. O controle do ruído nos hospitais deve ser considerado como uma das prioridades para melhoria de sua ambiência.

The increase in noise levels at hospitals could be attributed to many factors as incorporation of new technologies, concentration and flow of people and non-compliance of silence by the workers and patients. Noise provokes negatively impact the work process and people’s health. This study aimed a review the national literature on noise in hospital services in Brazil, by the analysis of the follow aspects: scientific research, measuring methods, noise levels in hospitals, and the findings and proposed strategies in studies. The noise level in Brazilian hospitals is above the recommended levels. There is an increasing knowledgement of this subject in Brazil. In order to expand this knowledge, intervention studies were recommended to eliminate the excessive noise into the hospitals. The noise control in hospitals should be considered as a priority to improve their surroundings.
