From: Use of powered air-purifying respirator (PAPR) by healthcare workers for preventing highly infectious viral diseases—a systematic review of evidence

Study characteristic Inclusion criteria Exclusion criteria
Types of participants Healthcare workers volunteers  
Intervention treatment Powered air-purifying respirator (PAPR) studied separately or within a personal protective equipment (PPE). Hybrid PAPR (hybrid PAPR is designed as both a self-contained breathing apparatus, PAPR and a standard mask—their design features may not reflect a true PAPR device intended for healthcare use)
Comparator Any other respiratory protective equipment, FFP3/FFP2/N95, or surgical masks.  
Outcomes -Healthcare worker infection rates utilizing PAPR technology within a PPE program as infection with SARS-Cov-2, SARS-Cov-1, EBOLA, or MERS;
-Contamination of skin or clothing measured with any type of test material to visualize contamination;
-Compliance with guidance on the use of PAPR measured with, e.g., observation checklist;
-Level of wearer comfort whilst using the PAPR;
-Objective and/or subjective measures of work of breathing during the use of PAPR;
-Costs of resource use of PAPR equipment;
-Impact of structured training programs on PAPR use;
 
Study design Randomized controlled trials
Non-randomized studies
Observational studies (cohort studies, case-control studies, cross-sectional studies, case series)
Case reports
Surveys
Study setting Inpatient care/critical care/intensive care;  
Timing Perioperative process-preadmission, preoperative, intraoperative, and postoperative setting Studies incorporating long-term (greater than 3 months) postoperative rehabilitation
