- Contributo para o estabelecimento de níveis de referência de diagnóstico em eletrofisiologia de intervenção: estudo de um centro em PortugalPublication . Videira, Sara; Pereira, José Manuel; Pereira, José ManuelA maioria dos procedimentos eletrofisiologia de intervenção necessitam de fluoroscopia expondo à radiação ionizante todos os intervenientes. O recurso a níveis de referência de diagnóstico (NRD) pode ser uma ferramenta profícua para promover a otimização de dose. O principal objetivo deste estudo consistiu em investigar as doses de exposição, determinando os NRD.
- Estudo do Stress nos Técnicos de RadiologiaPublication . Videira, Sara; Ventura, Sandra RuaO conceito de stress nem sempre foi consensual, no entanto, vários estudos têm documentado a relevância deste no contexto das diferentes profissões. O stress parece ser particularmente importante quando aplicado aos profissionais de saúde, estes estão frequentemente propensos ao burnout, termo que descreve o estado deexaustão prolongada e diminuição de interesse, especialmente em relação ao trabalho.
- Immersive technology applications in radiation protection for fluoroscopy - A systematic reviewPublication . Videira, Sara; Rodrigues, Matilde A.; Santos, Joana; da Silva, Manuela Vieira; Rodrigues, Matilde; Vieira da Silva, ManuelaImmersive technology is being increasingly incorporated into various professional and educational settings for occupational safety and health training. This review aims to assess the impact of immersive technology on the radiation protection (RP) of workers exposed to ionising radiation during fluoroscopy-guided procedures. Studies were collected from six databases on 3 April 2024: PubMed, Academic Search Complete, Scopus, Web of Science Core Collection, ScienceDirect, and Engineering Village. Additionally, studies were identified through snowball sampling techniques. Eligible studies assessed RP learning via immersive technology among healthcare workers or trainees exposed to ionising radiation from fluoroscopy in operating or interventional rooms. Additionally, only original research articles published in peer-reviewed journals and written in Portuguese, Spanish, English, and French were included. The review followed PRISMA and PICo, using narrative synthesis and bibliometric analysis. Quality was assessed using the Mixed Methods Appraisal Tool checklist. Ten studies involving 358 individuals (37 % trainees/students; 63 % workers) were analysed. All assessed the usefulness of RP education/training, and most (9/10) reported an improved understanding of scattered radiation. Technologies used included virtual reality (7/10), augmented reality (2/10), and mixed reality (1/10). Radiation scatter visualisation was present in the majority (9/10) of the studies, and 1/10 combined immersive technology with clinical training. These technologies enhance learning outcomes, support effective RP teaching, and optimise work practices. Integrating clinical training with RP education is essential. Implications for practice: This study supports healthcare professionals and educators in understanding how immersive technology (virtual, augmented, and mixed reality) is being applied and evaluated in training and real work contexts. Insights into methods, outcomes, and study populations inform practical use, while bibliometric data highlight key sources and authors for future reference and collaboration.
- Prevalence of the use of dosimeters for ionizing radiation from fluoroscopy − a systematic literature review and meta-analysisPublication . Videira, Sara; Rodrigues, Matilde; Santos, Joana; Guedes, Joana; Martins, João; Silva, Manuela Vieira da; Vieira da Silva, Manuela; Rodrigues, MatildeThis study aims to assess the prevalence of individual dosimeter use among workers exposed to ionizing radiation during fluoroscopy-guided procedures. Additionally, factors contributing to its use were identified. Studies were identified through searches in five databases on 13 April 2024. Additionally, snowballing techniques were employed. The review followed PRISMA guidelines and the CoCoPop model. A narrative synthesis, bibliometric analysis, and meta-analysis were performed. Study quality was assessed using the Joanna Briggs Institute checklist for prevalence studies. Fifty studies involving 11,067 individuals were included. Orthopedics/traumatology was the most studied specialty (46 %). Median use rates were: 24 %(IQR = 44 %) for eye lens dosimeters, 15 %(IQR = 13 %) for electronic real-time dosimeters, 27 %(IQR = 42 %) for wrist/finger dosimeters, 25 %(IQR = 23 %) for collar/ thyroid dosimeters and 5 % for ankle dosimeter; 15 %(IQR = 78 %) reported no monitoring device. In 15 studies (30 %) with 4,188 individuals (38 %), the overall prevalence of “always” using whole-body dosimeters was 43 % [95 %CI:24–62]. By continent, the highest prevalence was found in Africa (75 %[95 % CI: 46–95]), while the lowest was in the “Americas” (33 %[95 % CI: 16–52]). Significant moderator effects were found: higher prevalence in “Africa” (p = 0.04), “gastroenterology” (p = 0.04), and “involving radiology” (p = 0.01); lower in “orthopedics” (p = 0.01) and “physicians” (p = 0.03). No significant moderator effects were found: “very high Human Development Index” (p = 0.72) and “high Human Development Index” (p = 0.69). Studies showed moderate risk of bias (6/9), with little evidence of publication bias. Exposure doses may be underestimated due to the low prevalence of dosimeter use. Interventions targeting individual and organizational factors are needed to promote consistent use and improve safety.
- Worker's exposure to radiation in fluoroscopy, assessing and instruments: A systematic literature reviewPublication . Videira, Sara; Rodrigues, Matilde; Silva, Manuela Vieira daThis review aims to identify and analyze the instruments employed for assessing the overall performance of workers exposed to fluoroscopy during surgical procedures and/or interventional procedures, using the PRISMA methodology. The studies were located through searches conducted on PubMed, Web of Science, Lilacs, ScienceDirect, B-ON, EBSCOhost, and EBSCO Discovery Service on March 27, 2023. Additional studies were identified using backward and forward citation techniques. The PEO strategic model was followed. The search spanned studies published between 2012 and 2022. The quality of the studies underwent assessment using the Joanna Briggs Institute checklist for analytical cross-sectional studies. Out of the 23 studies identified, encompassing 3604 individuals, 12 (52%) addressed the reliability and/or validity of the instruments, while 3 (13%) focused on the development and psychometric testing of the instruments. Only 5 instruments (23%), validated and reliable, exclusively evaluated occupational radiological protection. The predominant dimension covered was knowledge (82%, n = 19). The population was assessed in 18 studies, pre- and post-intervention in 2 studies, and 21 studies provided recommendations or tools for improvement. Individuals in the studies utilized passive dosimeters (ranging from 5% to 98%), thyroid shields (15% to 98%), and aprons or lead skirts/coats (28% to 99%). The evidence quality was moderate (6/8). This study underscores the imperative to enhance compliance with protective and monitoring equipment. Furthermore, additional information is warranted concerning the validity and reliability of the instruments used, as well as the development of instruments that are both valid and reliable.
