That Group and the Sandwell and West Birmingham Hospitals NHS Trust are responsible for the care of 530,000 local people across North-West Birmingham and Sandwell.  \nSituation  \nRespirator t testing is a key component to any respiratory protection programme, protecting sta􀀞 from airborne  \nhazards. Anyone wears a tight tting respirator is required by HSE INDG 479 to perform respirator t testing. The Infection Prevention and Control Team at the Trust are responsible for providing over 4,000 frontline sta􀀞 members with a respirator t test to ensure the FFP3 masks they use are protecting them.  \nThere are two basic types of t tests: Quantitative Fit Testing (QNFT) and Qualitative Fit Testing (QLFT) .  \nQLFT is a low cost, subjective pass/fail test that exposes the respirator wearer to a chemical stimulant (while donning a test hood) such as Isoamyl Acetate, Sodium Saccharin, Bitrex or Irritant Smoke that can only be detected if the respirator leaks. The respirator wearer must breathe through their mouth, with tongue extended during the t test to enable detection (tasting) of leakage into the respirator. QLFT methods are often compromised by wellmeaning test operators who skip important steps, unknowingly invalidating the t test. To properly follow the protocol, a t test operator must squeeze the nebulizer bulb between 75 and 225 times for each t test performed. The temptation to get through the test faster is strong, especially when the same test operator t tests dozens of people per day.  \nUNDERSTANDING, ACCELERATED  \n“Very few sta had been 􀀞t tested due to lack of available training for 􀀞t testers, sta were losing con􀀞dence in how to perform the 􀀞t test and a high percentage of those tested were unclear as to whether they could taste the Bitrex® solution once a mask was 􀀞tted.”  \nCOMPARISON BETWEEN  \nQUALITATIVE AND QUANTITATIVE  \nFIT TESTING – AS COMPLETED BY  \nSTAFF AT CITY HOSPITAL BIRMINGHAM  \nQNFT is an objective test that involves the use of an instrument to measure how well the respirator ts. The measurement is not dependent on the person’s voluntary response. The instrument measures the t while the person performs a series of special exercises and automatically records the results. An aerosol challenge agent concentration (Cout) is measured outside the respirator and then again inside the respirator (Cin). The ratio of the two measurements (Cout/Cin) is called a t factor. The minimum t factor required by HSE, which should be achieved in each of the test exercises when carrying out a quantitative t test, is 2,000 fora full-face mask, 100 for a half-mask and 100 for FFP3, FFP2 and FFP1 ltering facepieces.  \nPrior to 2018 at the Sandwell and West Birmingham Hospitals, NHS Trust t testing was carried out using the Qualitative Hood method.“Very few sta􀀞 had been t tested due to lack of available training for t testers, sta􀀞 were losing con dence in how to perform the t test and a high percentage of those tested were unclear as to whether they could taste the Bitrex® solution once a mask was tted”, says Kasmiro Aheer, Infection, Prevention & Control Nurse Advisor. Consequently, some sta􀀞 lost con dence in the accuracy of the system.  \nSolution  \nTo resolve this issue, the Trust made the decision to invest in a Quantitative Fit Testing solution to eliminate the guesswork associated with QLFT methods such as Saccharin and Bitrex® and better measure respirator t. They chose to invest in the PortaCount® Respirator Fit Test","cbCaipVQYK8KLWvs","https://ap.wps.com/l/cbCaipVQYK8KLWvs","pdf",1156702,"English","# Introduction\n# Situation\n## Types of fit testing\n# Solution\n# Conclusion","[{\"question\":\"What is the key difference between qualitative and quantitative respirator fit testing?\",\"answer\":\"Qualitative fit testing relies on the wearer’s subjective ability to detect chemical stimulants when the mask leaks.
