Comparison of fit factors among healthcare providers working in the Emergency Department Center before and after training with three types of N95 and higher filter respirators.

ABSTRACT: INTRODUCTION:N95 or higher filtering respirators have been recommended in healthcare settings, although there is still a risk of infection due to the improper selection and wearing of respirators. We aimed to assess the effects of training with N95 or higher filter respirators on the protection performance of respirators among healthcare providers in the emergency medical center (EMC). METHODS:This randomized crossover study evaluated 23 healthcare providers. Quantitative fit tests (QNFTs) were performed before and after training using three types of N95 or higher filter respirators (cup-type, fold-type, valve-type). Training was performed by lecture, real-time feedback, and fit check. The primary outcome was the fit factor, and the secondary outcomes were overall fit factor, adequate protection rate, and respiratory preference. RESULTS:Fit factors, overall fit factor, and adequate protection rate were higher after training than before training for the 3 types of respirators (all P < .05). For normal breathing, fit factors before and after training were 121 (10-185) vs 192 (161-200) for cup-type, 200 (39-200) vs 200 (200-200) for fold-type, and 85 (18-157) vs 173 (117-200) for valve-type. For normal breathing, the adequate protection rates before and after training were 62 (0-100) vs 100 (90-100) for cup-type, 100 (0-100) vs 100 (100-100) for fold-type, and 19 (0-100) vs 100 (44-100) for valve-type (all P < .05). The most preferred respirator type was the valve-type (10 persons, 45.5%). CONCLUSIONS:Training on wearing an N95 or higher respirator improved the protection performance of respirators among healthcare providers working in the EMC. The selection of proper respirators and training would be beneficial to the safety of healthcare providers.

Project description:Healthcare personnel are at high risk for exposure to influenza by direct and indirect contact, droplets and aerosols, and by aerosol generating procedures. Information on air and surface influenza contamination is needed to assist in developing guidance for proper prevention and control strategies. To understand the vulnerabilities of healthcare personnel, we measured influenza in the breathing zone of healthcare personnel, in air and on surfaces within a healthcare setting, and on filtering facepiece respirators worn by healthcare personnel when conducting patient care.Thirty participants were recruited from an adult emergency department during the 2015 influenza season. Participants wore personal bioaerosol samplers for six hours of their work shift, submitted used filtering facepiece respirators and medical masks and completed questionnaires to assess frequency and types of interactions with potentially infected patients. Room air samples were collected using bioaerosol samplers, and surface swabs were collected from high-contact surfaces within the adult emergency department. Personal and room bioaerosol samples, surface swabs, and filtering facepiece respirators were analyzed for influenza A by polymerase chain reaction.Influenza was identified in 42% (53/125) of personal bioaerosol samples, 43% (28/ 96) of room bioaerosol samples, 76% (23/30) of pooled surface samples, and 25% (3/12) of the filtering facepiece respirators analyzed. Influenza copy numbers were greater in personal bioaerosol samples (17 to 631 copies) compared to room bioaerosol samples (16 to 323 copies). Regression analysis suggested that the amount of influenza in personal samples was approximately 2.3 times the amount in room samples (Wald ?2 = 16.21, p<0.001).Healthcare personnel may encounter increased concentrations of influenza virus when in close proximity to patients. Occupations that require contact with patients are at an increased risk for influenza exposure, which may occur throughout the influenza season. Filtering facepiece respirators may become contaminated with influenza when used during patient care.

Project description:BackgroundSince the declaration of the novel Corona Virus Disease (COVID-19) as a global pandemic by the World Health Organization, frontline healthcare workers (HCWs) and staff in the Emergency Departments (ED) started experiencing feelings of anxiety and fear from the projected exponential spread and the potential burden on the healthcare system and infrastructure. In Lebanon, major local factors contributing to this fear were the rapid escalation of COVID-19 cases across the country, the lack of preparedness, and the shortage of personal protective equipment, in addition to the evolving economic crisis and financial restrictions. This study aims to investigate the immediate psychological impact of the COVID-19 outbreak on ED staff working in a hospital environment in relation to their household income.MethodsSelf-reported cross-sectional survey was delivered to the frontline staff working at the Department of Emergency Medicine of AUBMC in Beirut, Lebanon. General demographic characteristics, scores of Generalized Anxiety Disorder 7 (GAD-7), scores of Patient Health Questionnaire 9 (PHQ-9), and scores of Burnout Measure-Short (BMS) version were collected.Results74 HCWs (49.6%) participated in the study. The mean age for participants was (31.78 ± 9.49). More than half of the participants were nurses and more than 70% reported a monthly salary of less than 2000 USD. The household income was negatively associated with the participants' scores on the GAD-7 and PHQ-9, but not the BMS. Previous mental health diagnosis was positively associated with the PHQ-9 and BMS scores, while seeking mental health care was negatively associated with the PHQ-9 and BMS scores.ConclusionAt our tertiary care center in a low-income, low resource country amidst the COVID-19 pandemic, the HCWs reported marked psychological disturbances on different scales. In particular, the financial burden was associated with increased anxiety and clinical depression, but was not associated with burnout.
