Background: Many organisations in Australia undertake systematic reviews to inform development of evidence-based guidelines or would like to do so. However, the substantial resources required to produce systematic reviews limit the feasibility of evidence-based approaches to guideline development. We are working with Australian guideline developers to design, build and test systems that make creating evidence-based guidelines easier and more efficient. Methods: To understand the evidence needs of guideline developers and to inform the development of potential tools and services, we conducted 16 semi-structured interviews with Australian guideline developers. Developers were involved in different types of guidelines, represented both new and established guideline groups, and had access to widely different levels of resources. Results: All guideline developers recognised the importance of having access to timely evidence to support their processes, but were frequently overwhelmed by the scale of this task. Groups developing new guidelines often underestimated the time, expertise and work involved in completing searching and screening. Many were grappling with the challenge of updating and were keen to explore alternatives to the blanket updating of the full guideline. Horizon-scanning and evidence signalling were seen as providing more pragmatic approaches to updating, although some were wary of challenges posed by receiving evidence on a too-frequent basis. Respondents were aware that new technologies, such as machine learning, offered potentially large time and resource savings. Conclusions: As well as the constant challenge of managing financial constraints, Australian guideline developers seeking to develop clinical guidelines face several critical challenges. These include acquiring appropriate methodological expertise, investing in information technology, coping with the proliferation of research output, feasible publication and dissemination options, and keeping guidance up to date.

Objectives There is a lack of evidence-based guidelines with regard to eye protection for aerosol-generating procedures in otolaryngology practice. In addition, some recommended personal protective equipment (PPE) is not compatible with commonly used ENT equipment. This study aims to investigate the degree of eye protection that commonly used PPE gives. Study Design Simulation model. Setting Simulation laboratory. Methods A custom-built setup was utilized to simulate the clinical scenario of a patient cough in proximity of a health care worker. A system that sprays a xanthan-fluorescein mixture was set up and calibrated to simulate a human cough. A mannequin with cellulose paper placed on its forehead, eyes, and mouth was fitted with various PPE combinations and exposed to the simulated cough. The degree of contamination on the cellulose papers was quantified with a fluorescent microscope able to detect aerosols ≥10 µm. Results When no eye protection was worn, 278 droplets/aerosols reached the eye area. The use of the surgical mask with an attached upward-facing shield alone resulted in only 2 droplets/aerosols reaching the eye area. In this experiment, safety glasses and goggles performed equally, as the addition of either brought the number of droplets/aerosols reaching the eye down to 0. Conclusion When used with an upward-facing face shield, there was no difference in the eye protection rendered by safety goggles or glasses in this study. Safety glasses may be considered a viable alternative to safety goggles in aerosol-generating procedures.
