This Special Collection is one of two collections on COVID-19, and it focuses on infection control and prevention measures. See also the companion Special Collection: Coronavirus (COVID-19): evidence relevant to critical care.
The 2019 Coronavirus outbreak (COVID-19) was declared a global Public Health Emergency by the World Health Organization (WHO) on 30th January 2020.
In order to ensure immediate access to Cochrane Reviews of potential relevance, this Cochrane Library Special Collection assembles Cochrane Reviews identified as most directly relevant to the prevention of infection. It includes reviews that evaluate the effects of interventions referenced in the WHO interim guidance for the 2019 coronavirus outbreak (28 January 2020), as well as other potentially relevant reviews from three Cochrane Networks: Cochrane Public Health and Health Systems; Cochrane Musculoskeletal, Oral, Skin and Sensory; and Cochrane Acute and Emergency Care. Many reviews in this collection have associated Cochrane Clinical Answers (CCAs), with links provided.
This Special Collection will be updated to ensure it remains applicable as the situation changes, and as WHO guidance evolves. It will also draw on the knowledge of Cochrane groups in affected regions.
The different natures of pathogens and their modes of transmission compared with what is currently known about COVID-19 may limit the applicability of the evidence summarized in these reviews. Please note that the reviews included in this Special Collection summarize evidence, and their inclusion does not mean that the interventions reviewed have been shown to be an effective prevention measure.
(Updated 10 March 2020: removed CCA from 'Personal protective equipment for preventing highly infectious diseases due to exposure to contaminated body fluids in healthcare staff')
Improving adherence to Standard Precautions for the control of health care‐associated infections
'Standard Precautions' refers to a system of actions, such as using personal protective equipment or adhering to safe handling of needles, that healthcare workers take to reduce the spread of germs in healthcare settings such as hospitals and nursing homes. This review assesses the effectiveness of interventions that target healthcare workers to improve adherence to Standard Precautions in patient care.
Personal protective equipment for preventing highly infectious diseases due to exposure to contaminated body fluids in healthcare staff
In epidemics of highly infectious diseases, such as Ebola Virus Disease or Severe Acute Respiratory Syndrome (SARS), healthcare workers are at much greater risk of infection than the general population, due to their contact with patients' contaminated body fluids. Contact precautions by means of personal protective equipment (PPE) can reduce the risk. This review evaluates which type of full body PPE and which method of donning or doffing PPE have the least risk of self‐contamination or infection for healthcare workers, and training methods to increase compliance with PPE protocols.
Behavioural interventions to promote workers' use of respiratory protective equipment
Respiratory hazards are common in the workplace. Depending on the hazard and exposure, the health consequences may include mild to life‐threatening illnesses from infectious agents, acute effects ranging from respiratory irritation to chronic lung conditions, or even cancer from exposure to chemicals or toxins. Use of respiratory protective equipment (RPE) is an important preventive measure in many occupational settings. RPE only offers protection when worn properly, when removed safely and when it is either replaced or maintained regularly. The effectiveness of behavioural interventions either directed at employers or organizations or directed at individual workers to promote RPE use in workers remains an important unanswered question. This review assesses the effects of any behavioural intervention either directed at organizations or at individual workers on observed or self‐reported RPE use in workers when compared to no intervention or an alternative intervention.
This Special Collection was developed by Lisa Bero (Senior Editor, Public Health and Health Systems), working with Toby Lasserson (Deputy Editor in Chief), Newton Opiyo (Associate Editor), Robin Featherstone (Information Specialist), and Monaz Mehta (Editor) in the Cochrane Editorial & Methods Department. Colleagues from the Public Health and Health Systems Network, Cochrane China Network, Cochrane Wounds, and Cochrane Acute Respiratory Infections Groups also provided input on the selection of reviews for this Special Collection.
