BackgroundNoise-induced hearing loss (NIHL) is a major preventable occupational health problem with 250 million people worldwide known to have disabling impairment of moderate to greater severity. The aims of the study are to estimate the prevalence of NIHL in the police force; and study its association with age, sex, duration of service (years), smoking and alcohol habits, use of hearing protective devices, as well as preexisting chronic diseases.MethodsA cross-sectional study was conducted on 543 police personnel who had undergone periodic medical examination over a 12-month period. The diagnostic criteria for NIHL were (1) history of occupational noise exposure, (2) bilateral hearing loss, (3) hearing loss of ≥ 25 dBA at 4,000 Hz in two consecutive audiograms, and (4) no significant medical history affecting hearing. Severity of NIHL was based on the World Health Organization grading.ResultsMales (74.8%) made up the majority of the police force. The mean age for police personnel was 35.55 ± 9.57 years, and the mean duration of service was 14.75 ± 9.39 years. Compliance with the usage of hearing protective devices was seen in 64.4%. The prevalence of NIHL in this study population was 34.2%, with a higher prevalence in males (37.7%) than in females (23.9%). The study also showed strong associations between NIHL and male sex (odds ratio, 1.9; P < 0.05), and hypertension (odds ratio, 3.3; P < 0.001). Overall, 93% were found to have mild NIHL, 3.5% had moderate NIHL, and 3.5% had severe NIHL. No police personnel were found to have profound hearing loss.ConclusionThe prevalence of NIHL in this study is high compared to other similar studies among police personnel. This study shows that increasing age, male, presence of hypertension, diabetes, and longer duration of service are significant associated factors for NIHL. Preventative strategies include health surveillance, implementation of a hearing conservation program, and legislation.
Objetivos: Avaliar o impacto da pandemia COVID-19 nas admissões de doentes com síndromes coronárias agudas (SCA) e angioplastia coronária primária (PPCI) em países que participam da iniciativa global Stent-Save a Life (SSL). Métodos e resultados: realizámos estudo observacional multicêntrico para coletar dados sobre admissões de doentes por ACS, STEMI e PPCI nos países participantes no SSL durante um período do surto COVID-19 (março e abril de 2020) em comparação com o período homólogo de 2019. Dos 32 países membros da iniciativa global SSL, 17 aceitaram participar no estudo (3 de África, 5 da Ásia, 6 da Europa e 3 da América Latina (LATAM)). Observámos uma redução global de 27,5% e 20,0% nos internamentos com SCA e STEMI, respetivamente. A diminuição do PPCI foi de 26,7%. Essa tendência foi observada em todos os países, exceto dois. Nestes dois países, a pandemia atingiu o pico mais tarde do que nos restantes. Conclusões: Este estudo mostra que o surto de COVID-19 foi associado a uma redução significativa de admissões hospitalares por SCA e STEMI, bem como uma redução de PPCI, o que pode ser explicado por fatores relacionados com o doente e com o sistema.
Background Healthcare workers (HCWs) are most at risk of contracting SARS-CoV-2 and COVID-19 infection. Their preparedness, as a result of provision and access to personal protective equipment (PPE), training programmes and awareness and practices on infection prevention and control measures, is integral for the prevention of infectious disease transmission. Objectives This study was conducted to assess the preparedness and practices of HCWs during COVID-19 first wave outbreak in Brunei Darussalam. Methods A cross-sectional study using a pre-designed and self-administered web-based questionnaire was conducted among HCWs from government and private health sectors ranging from primary to tertiary health facilities in Brunei Darussalam. Data were analysed using descriptive statistics, and chi-square test was used for statistical significance. Results A total of 511 HCWs participated in the study. Nurses (64%) and HCWs based at hospitals (66%) made up the majority of the study participants, with 74% having occupational exposure to COVID-19 cases. More than 99% of HCWs used respiratory PPE, and 94% used gloves. 74% had undergone respirator fit testing and 65% had received PPE awareness session within the last one year. Coverage in training programmes was found to be low among HCWs from private health facilities. Conclusions Majority of HCWs who had received updated training programmes and therefore were better prepared came from government health facilities. HCWs from private health facilities lacked preparedness training programmes and as such, there needs to be improvement to enhance preparedness measures in light of the ongoing COVID-19 pandemic and for future infectious disease outbreaks.
Globally, ILO estimates 374 million non-fatal and 380,500 fatal occupational accidents annually. Slips, trips, falls and contact with objects are the leading modes of injury, with extremities being the most common body part involved. Occupational accidents are of major concern for high risk occupational groups such as migrant workers, or work areas e.g. construction, manu-facturing, wholesale, and retail industries. This study was aimed to determine the prevalence of non-fatal occupational injuries and its trends among industry workers in Brunei Darussalam. A retrospective cross-sectional review of occupational accidents notified to the Occupational Health Division, Ministry of Health, over a five-year period from January 2014 until December 2018 was conducted. A total of 424 non-fatal occupational accidents were notified, with increasing trend from 44 in 2014 to 132 in 2018. Accidents were more common in males (98%), migrant workers (86%), in the 30–39 age group (42.5%), and in the construction industry (56.4%). Struck by object (37.7%) was the commonest cause and upper limb (43.9%) was the commonest body part involved. There is a need for workplaces to develop capabilities and support mechanisms for risk assessments, as well as auditing and reviewing performances to minimize occurrence of preventable occupational injuries.
