Despite widespread use of respiratory protective equipment in the U.S. healthcare workplace, there is very little clinical evidence that respirators prevent healthcare personnel (HCP) from airborne infectious diseases. Scientific investigation of this issue has been quite complicated, primarily because the use of respirators has become "the standard of care" for protection against airborne diseases in some instances, even without sufficient evidence to support their use. The key question remains: How well do respirators prevent airborne infectious diseases? The answer to this important question has important medical, public health, political and economic implications.

Condition Intervention
Respiratory Syncytial Viruses
Paramyxoviridae Infections
Device: N95 Respirator
Device: Medical/surgical mask

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Incidence of Respiratory Illness in Outpatient Healthcare Workers Who Wear Respirators or Medical Masks While Caring for Patients

Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • Protective Effects of N95 Respirators vs Medical Masks [ Time Frame: 2010-2015 ] [ Designated as safety issue: No ]
    To determine and analyze the magnitude of the change, if any, in incidence of laboratory confirmed influenza in healthcare practitioners wearing N95 respirators (2009 CDC guidelines) compared to medical masks (2007 guidelines).

  • Incidence Determination of Influenza and Viral Respiratory Illness [ Time Frame: 2010-2015 ] [ Designated as safety issue: No ]
    To improve understanding about the burden of influenza and other viral respiratory illnesses among HCPs stationed in outpatient settings by evaluating the incidence of laboratory-confirmed influenza.

Secondary Outcome Measures:
  • Protective Effects [ Time Frame: 2010-2015 ] [ Designated as safety issue: No ]
    • To determine and analyze the magnitude of the change, if any, in incidence of acute respiratory illness, influenza-like illness, and lab-confirmed respiratory illness in HCPs wearing N95 respirators compared to medical masks.
    • To examine the relationship between incidence and possible risk factors, including compliance, attitudes and opinions of HCPs and workplace exposures.

  • Incidence determination [ Time Frame: 2010-2015 ] [ Designated as safety issue: No ]
    - To measure the incidence of acute respiratory illness, influenza-like illness, and lab-confirmed respiratory illness in selected outpatient settings.
