Detailed Description
The study design is a methodological study with a quantitative approach, consisting of two phases. In phase 1 we will perform a virtual development and content validation by experts, of an innovative PPE assessment simulation. In phase 2 we will pilot the simulation protocol. Phase 2 will be conducted in the simulation center of the School of Nursing, University of São Paulo.
Phase 1 - For content validation, a minimum of 14 experts will be included [21]. The experts shall have experience in the themes of infection prevention and control (IPC) and simulation studies to validate the data collection tool. Considering that the intention is for the simulation protocol to be applicable in different countries, experts working in Brazil and in foreign countries will be included. The experts must be fluent in the Portuguese or English languages, have a minimum degree of specialization in the health areas, and have academic experience, as evidenced by publications in indexed scientific journals over the last three years. The search for experts working in Brazil will be performed through a platform of the researchers' resumes, available on the National Council for Scientific and Technological Development (CNPq) portal, as well as in reference lists of scientific papers on the theme. Experts working in other countries will also be selected through the reference list of scientific papers and after analyzing the information recorded in the Open Researcher and Contributor platform: ID (ORCID).
Phase 2 - The simulation protocol piloting will include HCW with work experience in critical care (intensive care units and emergency department) for adult patients, from the following professional categories: physicians, nurses, nursing technicians and physiotherapists, with at least one year of experience, and regardless of gender. Professionals taking part in simulation studies in the last year, with similar content, will be excluded. The convenience sample will be invited by word of mouth and by means of posters in selected hospitals in São Paulo.
After reaching consensus regarding the clinical simulation script among the experts, the protocol will be piloted. After accepting to take part in the research by signing a written consent form, the participants will be emailed informational materials about the activities that will be performed and instructional material about the PPE items that will be used.
Two identical sessions will be conducted using the cross-over method with all participants, so that the same participant performs the tasks using the innovative PPE and the comparative PPE, allowing the participants compare characteristics of both PPE. The PPE use sequence and the PPE type will be randomized to minimize biases. Between both sessions there will a 30-minute break for the participants.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Content Validity of the items included in the "Innovative PPE assessment tool" and in the "Simulation scenario script"
Time Frame: During validation phase, the experts will record their answers by email. Up to three consultation rounds will be conducted.
|
The experts will assess the documents sent by email and will be instructed to record their opinions, answering in a five-point Likert-type scale ("Strongly agree", "Partially agree", "Neither agree nor disagree", "Partially disagree" and "Strongly disagree") whether they agree or disagree regarding the pertinence, clarity and relevance of each item.
The experts' responses will be analyzed and the Content Validity Index (CVI) as well as the Intraclass Correlation Coefficient (ICC) will be calculated.
|
During validation phase, the experts will record their answers by email. Up to three consultation rounds will be conducted.

Errors during PPE assembly/preparation, donning and doffing
Time Frame: Once for each PPE, while the participant is performing the task in the simulation session

A fluorescent tracer will be used, which is a transparent dye that only becomes visible when exposed to ultraviolet light. The solution is an abrasion-resistant solution but can be easily removed with a standard cleaning procedure. The tracer will be applied to the PPE used before the start of simulation activities. After the PPE doffing, the researchers will directly visualize the body areas contaminated with the dye, in a dark room, using ultraviolet light and will note this in the data collection tool. The number of contaminated body areas will be considered. The researcher will observe the body areas and will record the following data: - Did the participant have any of body area contaminated with the dye after doffing? Yes or Not. If yes, register which areas have been contaminated. |

Complementary Content Analysis - qualitative data
Time Frame: Two focus group meetings will be held, one with the Brazilian experts and another with the international experts, up to a month after the end of the pilot test.
|
Once the simulation protocol piloting phase is finished, the images obtained will be edited and will be sent to the same experts who took part in the first evaluation (Validation phase) of the simulation script for them to record their opinions on the piloting. After the experts analyze the images, two focus group meetings will be held, one with the national experts and another with their international counterparts, through an online meeting to discuss and reach agreements about the data collection script and the simulation protocol script. The following question will guide the focus group discussion: "In the format in which they were prepared, does the data collection script and the simulation protocol allow adequately assess innovation in PPE?". The comments from experts during the focus group will be analyzed considering following the technique proposed by Bardin (2011), in view of the Consolidated Framework for Implementation Research (CFIR) constructs. |
Two focus group meetings will be held, one with the Brazilian experts and another with the international experts, up to a month after the end of the pilot test.
