1 Overview of NPPTL Healthcare Respiratory Protection Surveillance and Intervention Research Debra A. Novak PhD, RN CDC/NIOSH National Personal Protective Technology Laboratory (NPPTL) Pittsburgh, PA University of Cincinnati September 16, 2014
2 Learning Objectives Upon completion of this presentation the participants will: Understand recent clinical events and related research findings evidencing marginal compliance with recommended proper use of respiratory personal protective equipment (PPE). Identify suggested strategies to reinforce healthcare workers’ proper use of respiratory protection.
3 Why Healthcare Respiratory Protection is a Priority Healthcare is the fastest-growing sector of the U.S. economy, employing over 18 million workers Healthcare personnel (HCP) are at higher risk of exposure to infectious respiratory pathogens than workers in non- healthcare settings Preferred methods of reducing exposure (elimination, substitution, administrative, and engineering controls) are often not possible or practical to implement, especially during an emerging outbreak or pandemic.
4 Occupational Statistics Every Day 9,000 U.S. workers sustain disabling injuries 16 die from a work injury 137 die from work-related illnesses Healthcare Industry In 2007 general medical and surgical hospitals reported more injuries and illnesses than any other industry ….. in 2010 hospitals again held the # 1 position with over 30% of all lost time nonfatal occupational illness and injuries. OSHA describes healthcare as having a “weak culture of worker safety”……. “Very poor safety performers.”
5 Compliance with Use of PPE Evidence of marginal compliance with respiratory protection guidance….less than 60%. Specifically, there was a lack of adherence to the proper use of infection control precautions (respiratory protection) documented during the H1N1 influenza pandemic. CDC “ Infection control (IC) practices are not being faithfully followed... failure to recognize patients and activities that warrant specific IC practices.” CDC “ Compliance with routine infection control procedures is an increasingly important issue.” OSHA 5 https://www.osha.gov/OshDoc/Directive_pdf/CPL_ pdf

11 Respiratory Protection in Healthcare N95 Filtering Facepiece Respirators (FFRs) are the most commonly used type of respirator in healthcare NIOSH 42 CFR Part 84 FDA “Surgical N95 respirator”
12 Clinical Events California Bacterial Meningitis H1N1 NPPTL Research Initiatives REACH I REACH II AAOHN Survey Clinical Challenges Compliance with Proper Use
13 California Bacterial Meningitis Background Two individuals became seriously ill and hospitalized with a highly virulent strain of meningitis. Hefty fines were issued by Cal/OSHA to the medical center and the police and fire departments. Lesson The individuals who voluntarily wore respiratory protection (N95s) did not get sick. Accessed from:
14 H1N1 Respirator Supply Issues N95 supply shortages… stockpiles rapidly depleted Just-in time and traditional supply chains collapsed Where to access re-supply of respirators? When to use a surgical mask? When to use an N95? What to use? How to properly use recommended equipment (N95)? How to mass fit-test employees? How to fit-test for the re-supplied models of N95s ?
15 H1N1 Take Home Messages Healthcare organizations displayed confusion. Preparedness was weak….plans exist on paper. Most HCWs recall fit test at hire with minimal updates. ongoing RPE training was a practice gap. Fit-testing was the focus…ongoing RPE training was a practice gap. HCWs are infrequent and complacent users of RPE. HCWs are improperly using (donning and doffing) respirators. Respirators (N95s) used for TB. unprotected HCW unprotected H1N1 exposures & deaths were reported.

18 Overview Purpose of the Study Assess the usage of respiratory protection for influenza exposure among healthcare workers. Study Methods Sixteen healthcare organizations participated in the study. Onsite surveys (15-21) and observational data collection methods were employed in each facility. 204 healthcare workers participated in the study from a variety of clinical specialties. Approved by California and NIOSH IRBs as public health practice
19 Respirator Reuse No – 116 (57.7%) Yes – 85 (42.3%) Note - More than one response may have been selected by each respondent N=85
20 “How do you know that you need to wear a respirator?” Note - More than one response may have been selected by each respondent N=201
21 What do healthcare workers believe? N=203
22 Other findings 50% of the hospital managers reported that their facility had experienced a shortage of respirators between April 2009 and the survey period (January 20 - February 23, 2010). The observational data indicate improper use of respiratory protective equipment as evidenced by donning and doffing practices. Not performing a seal check Improper strap placement Touching the facepiece upon doffing
23 Problems with N95 Respirators Note - More than one response may have been selected by each respondent
NPPTL Year Month Day Initials BRANCH 24 REACH II Purpose: Evaluate hospitals’ respiratory protection programs and respirator usage in five regions of the U.S. Regions: North Carolina, Minnesota/Illinois, New York, Michigan, California Data Set Includes: 98 Hospitals 1500 hospital managers, unit managers & healthcare workers (HCW) 300 demonstrations of donning & doffing
NPPTL Year Month Day Initials BRANCH CDC recommendations regarding respiratory protection in the presence of patients with seasonal influenza. Healthcare workers appear to be unaware of the recommended procedures when in close contact with these patients. Healthcare workers and their managers (both hospital and unit managers) appear to be unaware of the recommended protection while performing aerosol-generating procedures. 2. Best practice procedures for monitoring and evaluating the hospital’s respiratory protection program (RPP). The REACH II surveys suggest that many hospitals do not have a formal mechanism for evaluating their RPP or documenting respirator use, supply, defects, or problems; do not maintain their respirators properly; do not seek input from healthcare workers; and do not determine whether staff are using respirators as required. REACH II Findings
NPPTL Year Month Day Initials BRANCH Medical evaluation and fit testing requirements. Most hospitals are not following guidelines about the frequency of medical evaluations or methods for notifying staff about which model and size of respirators they may use. 4 Training requirements. The REACH II surveys suggest healthcare workers are unaware of how often training is required and that staff are not allowed to wear a respirator without periodic training. 5. Fit testing. Healthcare workers at most REACH II hospitals are not aware of the required procedures if they cannot successfully be fitted with a respirator. 6. Manufacturers’ recommendations for respirator use. Healthcare workers at many REACH II hospitals did not demonstrate awareness of user seal check procedures, proper respirator removal and disposal, using the straps, and the correct placement of the straps. REACH II Findings
NPPTL Year Month Day Initials BRANCH CDC recommendations regarding respiratory protection in the presence of patients with infectious disease. In over a third of the REACH II hospitals, healthcare workers were unaware of required procedures. The survey data suggested that hospital managers and unit managers tended to be aware of recommended/required practice, whereas many healthcare workers were not. In addition, this pattern was evident in almost all of the topics addressed in this study: Adherence rates based on the hospital manager and unit manager surveys were higher than the rates based on the healthcare workers survey. Thus, the closer respondents were to the “bedside” (i.e., the more patient contact they had), the less likely they were to provide answers that reflected knowledge of the recommended or required respiratory protection practice.

NPPTL Year Month Day Initials BRANCH 30 What happens if an employee cannot be successfully fit tested?
NPPTL Year Month Day Initials BRANCH 31 During the program evaluation, do you determine whether respirators are being maintained properly? For example, PAPRs are disinfected after use.
NPPTL Year Month Day Initials BRANCH 32 Does your facility have a written policy for redonning (reuse) of respirators? Yes No Don’t Know How are employees instructed to store respirators between doffing (removing) and redonning? In a plastic bag In a paper (breathable) bag Carried by the employee Other (specify) Don’t know REACH II Reuse Items
NPPTL Year Month Day Initials BRANCH 33 REACH II Guidance Items Which guidelines are used to determine the infectious disease exposures (i.e., transmission precautions) that require respiratory protection? CDC recommandations OSHA State Department of Health recommendations Other (specify) What would trigger the staff’s use of respiratory protection? Patient’s signs and symptoms (i.e., fever, cough, sputum production) Laboratory confirmation of disease Physician order Sign on the door of a patient’s room Verbally informed by co-workers Other – Depending on unit/department
NPPTL Year Month Day Initials BRANCH 34 REACH II Summary REACH II findings indicate that knowledge related to N95 FFR reuse policy, storage of reused N95 FFRs needs to be reinforced. REACH II observational findings indicate that the proper use procedures for donning and doffing need to be reinforced. Reuse and Extended Use Policies and Procedures should be developed within the organization and in collaboration with community emergency preparedness agencies. Best practice healthcare organizations utilize a Respiratory Protection team approach (i.e. Occup.Health, Safety, IC, Emergency Preparedness).
NPPTL Year Month Day Initials BRANCH 35 REACH I &II Common Findings Respiratory protection program plans exist on paper Response differences between HCWs, unit & hospital managers regarding operations of RPP. Most HCWs recall fit test at hire with minimal updates. Fit-testing is the focus…ongoing preparedness training isn’t (<15 minutes annually). HCWs are unclear about WHEN to use respiratory protection. HCWs are unclear about WHAT type of respirator should be used. HCWs are unclear about HOW to properly donn and doff respirators (strap positions, seal checks, disposal).

NPPTL Year Month Day Initials BRANCH 41 IOM Letter Report (2011) Improving OHN Education and Training Occupational health nurses are front-line advocates for preventing workers injury and illness and promoting a culture of safety health in the workplace….. Committee found varying amounts of dedicated time and resources devoted to respiratory protection content ….. Committee generated seven recommendations to strengthen respiratory protection education and training…..
NPPTL Year Month Day Initials BRANCH 42 Respiratory Protection Educational Competencies and Training Project The Working Advisory Group on Respiratory Protection initiated a grassroots, non-funded national survey of occupational health nurses (OHNs) to address the IOM Letter Report’s Recommendation 1. Online / web-based survey, conducted by AAOHN, opened May 2, 2012 with data collection ongoing until May 30, 2,263 respondents, averaging 17 years experience, professionally affiliated and OHN certified.
NPPTL Year Month Day Initials BRANCH 43 AAOHN Survey Findings 88% work in facilities with respiratory protection programs (RPP). 50% of the OHNs report being primarily responsible for RPP. 50% perform respiratory fit testing. NIOSH spirometry certification is current for 31% of the sample. 27% report being not at all comfortable or slight comfort and 20% report moderate comfort in explaining the difference between a surgical mask and an N95. 67% reported that their respiratory protection educational preparation occurred on-the-job. Years of OHN experience was associated with both comfort and self-perceived RP competency.
NPPTL Year Month Day Initials BRANCH 44 The top three industries represented were healthcare (35%), manufacturing (26%), and government (9%). Many types of professionals are involved with RPPs – Safety, Industrial Hygiene, etc. Safety culture was significantly associated with both competence and comfort in RP. Average comfort level for all aspects of RPP was in the moderate range with highest comfort in medical evaluation for respirator use. Writing a RPP policy and inspection, cleaning and repair of respiratory equipment had lowest comfort scores. Survey Findings
