THE NATIONAL ACADEMIES

Advisers to the Nation on Science, Engineering, and Medicine


The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.


The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering.


The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education Dr. Harvey V. Fineberg is president of the Institute of Medicine.


The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council.

Preface

This Committee’s task—to examine and assess the adequacy and validity of the National Institute for Occupational Safety and Health (NIOSH)-sponsored Anthrotech Survey of U.S. Respirator Users—was as challenging as it was important. Having effective respiratory protection can be, and often is, a matter of life and death. Yet the scientific bases for developing and fitting effective respiratory protection remain more art than science.

A Los Alamos National Laboratory (LANL) respirator fit-test panel, performed in the 1970s and based on a survey of Air Force personnel, has been the basis for testing and certifying respirators for the past 30 years. It is not clear, however, that the Air Force population adequately represented the range of workers even then, and more recent changes in the composition and diversity of the U.S. workforce may make it even less suitable. Developing new test panels for respirators that will fit the changing “face” of the U.S. workforce became an obvious need that NIOSH sought to address in contracting with Anthrotech to conduct a new survey of the U.S. workforce in 2001. NIOSH is to be commended for taking that initiative and also for seeking an independent review of the study’s outcome by the Institute of Medicine (IOM) (as presented in this report).

The conduct of our work was interrupted after our second meeting in order to accommodate an urgent request from the DHHS Office of the Secretary for advice on the potential reusability of disposable face masks in protecting against pandemic flu. Some of our committee members served on that committee, and then returned 6 months later to reconvene in addressing this committee’s charge.

It is always easier to critique someone else’s work than it is to develop and conduct new work. And it is with this awareness that our committee offers our evaluation and assessment. We found many weaknesses in the collection and analysis of the data that were used to develop the proposed face panels. The Anthrotech survey, rather than using novel methodology, served more as an update of a 30-year-old strategy with a larger sample population. The study would have been improved greatly by assuring that the sample was representative of workers who should be using respirators, by validating and incorporating three dimensional measures, and by measuring quantitative fit. There was also a surprising lack of detailed information about the methods that were used in its conduct. Nonetheless, the proposed NIOSH face panel represents an improvement over the existing LANL face panel, and its application is likely to improve the availability of respirators that fit a broader segment of the workforce.

The committee was not charged to comment on whether or not the survey should be redone. However, the Anthrotech research plan, survey, and data analysis had weaknesses that will limit their reliability for NIOSH purposes. As resources and time become available, NIOSH might undertake a new study with a different strategy and research plan.

The committee acknowledges and thanks the IOM staff who supported its efforts, the numerous NIOSH staff who provided detailed information and briefings, and others who provided information in open meetings, and otherwise during the conduct of this study. Appendix A lists the public meeting agendas and meeting participants. The committee most importantly thanks NIOSH for having asked these questions in the first place, for working on updating the respirator test standards, and for having a steadfast dedication to scientific research in support of the health of the public.

NIOSH and the Occupational Safety and Health Administration (OSHA) share responsibility for overseeing respiratory protection in the workplace and have established regulations for this purpose. Specifically, NIOSH has issued regulations which define respirator testing and certification. OSHA has issued regulations which define conditions under which employers are required to maintain respiratory protection programs in general industry, shipyards, marine terminals, and construction.

In 2005, NIOSH contracted with the Institute of Medicine (IOM) to study the NIOSH-sponsored Anthrotech study along with its supporting information and reports, and to examine and report on the adequacy and relevance of the study protocol, the analyses conducted, the resulting anthropometric dataset, and the appropriateness of the respirator fit-test panels derived from the new dataset.

Assessment of the NIOSH Head-and-Face Anthropometric Survey of U.S. Respirator Users focuses on the establishment of the scientific base required for certification standards of respirators, not their use in the workplace. This report describes and analyzes the anthropometric measurements performed by Anthrotech for its NIOSH-sponsored study. This report looks at the survey methods used by Anthrotech in the study, and examines how Anthrotech analyzed its data to derive fit-test panels and suggests some ways that analysis could be improved. This report discusses future directions, pointing toward further analyses of the data and offers suggestions for moving from research to practice.
