NCT02082158

Brief Summary

This VA-based study will obtain feedback from healthcare workers via validated survey instrument on the comfort and tolerability of wearing current models of N95 respirators and novel respirator designs currently in development. There will be 4 novel respirators and 1 commonly used respirator (not locally used) to compare to a locally used respirator, which is familiar to participants. Comparisons will be examined between each of the first 5 models with the locally used control using Dunnett's t-test.

Outcome Measures

Primary Outcomes (1)

  • To Collect Healthcare Worker Feedback About Perceived Comfort of Novel Respirator Designs

    Subject will participate in set study activities wearing the respirator that he/she was randomized to. Following, Subjects will answer questions concerning comfort of respirator utilizing a Likert scale instrument that has been validated to capture comfort and tolerability assessments. This is a single visit study; there is no follow-up. Comfort and tolerability measurements will be compared between new and standard respirator models. The Respirator Comfort, Wearing Experience and Function Instrument (R-COMFI) is made up of 3 subscales: 1) Discomfort subscale (10 items, scored 0 to 2, score range of 0-20), 2) General Wearing Experience subscale (6 items, scored 0 to 2, score range of 0-12), and the 3) Function subscale (5 items, scored 0 to 3, score range of 0-15). An overall comfort and tolerability score is achieved by the sum total of all subscales. The instrument score range is 0-47. Higher scores equate to higher levels of discomfort and inability to tolerate respirator.

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • VA or UF Health Shands Hospital clinical healthcare worker
  • Has been previously fit-tested to a N95 respirator
  • Is able to pass fit-testing on the model of respirator he/she is randomized to

You may not qualify if:

  • Is pregnant
  • Has a health condition that prevents him/her from wearing a respirator
  • Has physical characteristics that may interfere with his/her ability to attain an adequate facial seal when fit-tested (e.g. growth of facial hair, facial scarring)
  • Has any condition which could, in the opinion of the investigator, place the participant at risk or interfere with data integrity. This includes a previous reaction to inhalation of both the Bitrex or saccharin solution used during fit-testing procedures.
