- Biological risk assessment: a challenge for occupational health and safety practitioners during Covi-19 (Sars-CoV-2) PandemicPublication . Alberto Alves Carvalhais, Carlos; Querido, Micaela Micaela; Pereira, Cristiana C.; Santos, JoanaThe COVID-19 global pandemic brought several challenges to occupational safety and health practice. One of these is the need to (re)assess the occupational risks, particularly, biological risks.
- Psychometric properties of the portuguese version of the occupational fatigue exhaustion/recovery (OFER) scale among industrial shift workersPublication . Santos, Joana; Ramos, Catarina; Silva, André; Amorim, Sara; Winwood, Peter; Alberto Alves Carvalhais, CarlosReliable and valid instruments are essential for understanding fatigue in occupational settings. This study analyzed the psychometric properties of the Portuguese version of the Occupational Fatigue Exhaustion/Recovery (OFER). A cross-sectional study was conducted with 260 workers (M = 46.52 ± 13.16 years) from a textile industry, exposed to shift work. Convergent and discriminant validity, internal consistency reliability and exploratory and confirmatory factor analysis were performed. Results showed an adequate fit to data (χ2 (84) = 209,102, CFI = 0.936, GFI = 0.902, RMSEA = 0.076 CI90% (0.063–0.089)), yielding a 13-item, three factor structure. Two items were removed due to low factor loading. The OFER presented an adequate internal consistency, with the subscales presenting good reliability values (Chronic Fatigue (α = 0.81), Acute Fatigue (α = 0.84) and Recovery between Shifts (α = 0.77)). Findings suggest that the Portuguese version of OFER can be a useful tool to assess occupational fatigue of shift workers and prevent work related injuries.
- The impact of structural changes on sound pressure levels in a neonatal intensive care unitPublication . Alberto Alves Carvalhais, Carlos; Rodrigues, Celia; Xavier, Ana; Vieira Da Silva, Manuela; Santos, JoanaThe design of neonatal intensive care units (NICU) influences both patient safety and clinical outcomes as well as the acoustic conditions. In NICU exposure to sound pressure levels above the recommended can affect both neonates and healthcare staff. This study aimed to evaluate the sound pressure levels and to assess noise perception of professionals in a NICU before and after structural modifications and layout redesign. The measurements were performed with a sound level meter. A questionnaire was given to staff before and after the intervention. The opinion of healthcare staff regarding noise in NICU was better after the intervention, when compared with the responses previously given. The results showed that noise levels were excessive in the NICU (before and after), exceeding the inter national recommendations, with the levels ranging between 46.6 dBA to 57.8 dBA before and 52.0 dBA to 54.0 dBA after intervention. Overall, there is a need for more research in order to verify the effectiveness of some actions and strategies to reduce the impact of noise in NICU.
