RESUMEN

In the United States, the majority of waste workers work with solid waste. In solid waste operations, collection, sorting, and disposal can lead to elevated biohazard exposures (e.g., bioaerosols, bloodborne and other pathogens, human and animal excreta). This cross-sectional pilot study aimed to characterize solid waste worker perception of biohazard exposures, as well as worker preparedness and available resources (e.g., access to personal protective equipment, level of training) to address potential biohazard exposures. Three sites were surveyed: (1) a family-owned, small-scale waste disposal facility, (2) a county-level, recycling-only facility, and (3) an industrial-sized, large-scale facility that contains a hauling and landfill division. Survey items characterized occupational biohazards, resources to mitigate and manage those biohazards, and worker perceptions of biohazard exposures. Descriptive statistics were generated. The majority of workers did not report regularly coming into contact with blood, feces, and bodily fluids (79%). As such, less than one-fifth were extremely concerned about potential illness from biological exposures (19%). Yet, most workers surveyed (71%) reported an accidental laceration/cut that would potentially expose workers to biohazards. This study highlights the need for additional research on knowledge of exposure pathways and perceptions of the severity of exposure among this occupational group.

RESUMEN

OBJECTIVE: In 2019, our team conducted a literature review of air medical evacuation high-level containment transport (AE-HLCT) of patients infected with high-consequence pathogens. Since that publication, the coronavirus disease 2019 (COVID-19) pandemic has resulted in numerous air medical evacuations. We re-examined the new literature associated with AE-HLCTs to determine new innovations developed as a result of the pandemic. METHODS: A literature search was performed in PubMed/MEDLINE from February 2019 to October 2021. The authors screened abstracts for the inclusion criteria and reviewed full articles if the abstract was relevant to the aim. RESULTS: Our search criteria yielded 19 publications. Many of the early transports of patients with COVID-19 used established protocols for AE-HLCT, which were built from the most recent transports of patients with Ebola virus disease. Innovations from the identified articles are subdivided into preflight considerations, in-flight operations, and postflight operations. CONCLUSION: Lessons gleaned from AE-HLCTs of patients with COVID-19 in the early weeks of the pandemic, when little was known about transmission or the severity of the novel disease, have advanced the field of AE-HLCT. Teams that had never conducted such transports now have experience and processes. However, more research into AE-HLCT is needed, including research related to single-patient portable isolation units as well as containerized/multipatient transportation systems.

RESUMEN

With the increasing number of highly infectious disease incidents, outbreaks, and pandemics in our society (e.g., Ebola virus disease, Lassa fever, coronavirus diseases), the need for consensus and best practices on highly infectious decedent management is critical. In January 2020, a workshop of subject matter experts from across the world convened to discuss highly infectious live patient transport and highly infectious decedent management best practices. This commentary focuses on the highly infectious decedent management component of the workshop. The absence of guidance or disparate guidance on highly infectious decedent management can increase occupational safety and health risks for death care sector workers. To address this issue, the authorship presents these consensus recommendations on best practices in highly infectious decedent management, including discussion of what is considered a highly infectious decedent; scalability and storage for casualty events; integration of key stakeholders; infection control and facility considerations; transport; care and autopsy; psychological, ethical, and cultural considerations as well as multi-national care perspectives. These consensus recommendations are not intended to be exhaustive but rather to underscore this overlooked area and serve as a starting point for much-needed conversations.

RESUMEN

Personal protective equipment used by healthcare workers to mitigate disease transmission risks while caring for patients with high-consequence infectious diseases can impair normal body cooling mechanisms and exacerbate physiological strain. Symptoms of heat strain (e.g., cognitive impairment, confusion, muscle cramping) are especially harmful in the high-risk environment of high-consequence infectious disease care. In this pilot study, the core body temperatures of healthcare workers were assessed using an ingestible, wireless-transmission thermometer while performing patient care tasks common to a high-level isolation unit setting in powered air purifying respirator (PAPR)-level. The objective was to determine the potential for occupational health hazard due to heat stress in an environmentally controlled unit. Maximum core temperatures of the six participants ranged from 37.4 °C (99.3 °F) to 39.9 °C (103.8°F) during the 4-hr shift; core temperatures of half (n = 3) of the participants exceeded 38.5 °C (101.3 °F), the upper core temperature limit. Future investigations are needed to identify other heat stress risks both in and outside of controlled units. The ongoing COVID-19 pandemic offers unique opportunities for field-based research on risks of heat stress related to personal protective equipment in healthcare workers that can lead to both short- and long-term innovations in this field.

RESUMEN

We surveyed 56 Ebola treatment centers (ETCs) in the United States and identified costs incurred since 2014 ($1.76 million/ETC) and sustainability strategies. ETCs reported heavy reliance on federal funding. It is uncertain if, or for how long, ETCs can maintain capabilities should federal funding expire in 2020.

RESUMEN

In the United States of America, Medical Examiners and Coroners (ME/Cs) investigate approximately 20% of all deaths. Unexpected deaths, such as those occurring due to a deceased person under investigation for a highly infectious disease, are likely to fall under ME/C jurisdiction, thereby placing the ME/C and other morgue personnel at increased risk of contracting an occupationally acquired infection. This survey of U.S. ME/Cs' capabilities to address highly infectious decedents aimed to determine opportunities for improvement at ME/C facilities serving a state or metropolitan area. Data for this study was gathered via an electronic survey. Of the 177 electronic surveys that were distributed, the overall response rate was N = 108 (61%), with 99 of those 108 respondents completing all the questions within the survey. At least one ME/C responded from 47 of 50 states, and the District of Columbia. Select results were: less than half of respondents (44%) stated that their office had been involved in handling a suspected or confirmed highly infectious remains case and responses indicated medical examiners. Additionally, ME/C altered their personal protective equipment based on suspected versus confirmed highly infectious remains rather than taking an all-hazards approach. Standard operating procedures or guidelines should be updated to take an all-hazards approach, best-practices on handling highly infectious remains could be integrated into a standardized education, and evidence-based information on appropriate personal protective equipment selection could be incorporated into a widely disseminated learning module for addressing suspected or confirmed highly infectious remains, as those areas were revealed to be currently lacking.

RESUMEN

INTRODUCTION: Aeromedical evacuation (AE) is a challenging process, further complicated when a patient has a highly hazardous communicable disease (HHCD). We conducted a review of the literature to evaluate the processes and procedures utilized for safe AE high-level containment transport (AE-HLCT) of patients with HHCDs. METHODS: A literature search was performed in PubMed/MEDLINE (from 1966 through January 2019). Authors screened abstracts for inclusion criteria and full articles were reviewed if the abstract was deemed to contain information related to the aim. RESULTS: Our search criteria yielded 14 publications and were separated based upon publication dates, with the natural break point being the beginning of the 2013-2016 Ebola virus disease epidemic. Best practices and recommendations from identified articles are subdivided into pre-flight preparations, inflight operations, and post-flight procedures. CONCLUSIONS: Limited peer-reviewed literature exists on AE-HLCT, including important aspects related to healthcare worker fatigue, alertness, shift scheduling, and clinical care performance. This hinders the sharing of best practices to inform evacuations and equip teams for future outbreaks. Despite the successful use of different aircraft and technologies, the unique nature of the mission opens the opportunity for greater coordination and development of consensus standards for AE-HLCT operations.

RESUMEN

In late 2014, 56 hospitals in the United States were designated by state and federal public health authorities as specially designed high-level isolation units (HLIUs) equipped with advanced infrastructure, laboratory capabilities, and trained staff to care for patients with highly hazardous communicable diseases (HHCDs), such as Ebola virus disease. This survey describes the clinical laboratory support capabilities of U.S. HLIUs, including the specific test menus that HLIUs have identified to safely manage HHCD patients and the locations where such testing would be performed. In spring 2016, a survey was electronically distributed, as a fillable pdf file, to the 56 U.S. HLIUs. Site representatives completed the surveys, and data were coded and analyzed in an electronic spreadsheet, using descriptive statistics. Thirty-six HLIUs (64%) responded, and 33 completed the laboratory capabilities section. Thirty-one HLIUs (94%) had performed risk analyses for all laboratory procedures and equipment. Twenty-nine (88%) had decontamination procedures specified for all laboratory equipment used for patients with suspected or confirmed HHCDs. On-site laboratories in 27 HLIUs (81%) had the capacity to inventory and to securely store HHCD patient specimens. Ten HLIUs (31%) had at least one test they would conduct within the patient isolation room. The high-risk nature of HHCDs and the occupational exposures that may occur in clinical laboratories demand advanced preparation and risk assessment of work practices, laboratory equipment, and instrumentation by HLIU laboratories. Although risk analyses of clinical laboratory testing and equipment that HLIUs have conducted have likely focused on those for Ebola virus, HLIUs must be prepared to revise their current procedures for other HHCDs.

RESUMEN

OBJECTIVE: To describe strategies used by US high-level isolation units (HLIUs) to recruit, train, and sustain a full team of multidisciplinary staff and identify how units are secured. BACKGROUND: Fifty-six US hospitals have been designated HLIUs, capable of providing safe care to patients with highly infectious disease. METHODS: An electronic survey was administered to the 56 HLIUs in spring of 2016. Responses were collected via a fillable PDF and analyzed using descriptive statistics. RESULTS: Thirty-six HLIUs (64%) responded; 33 completed surveys, and 3 reported no longer being a designated HLIU. HLIUs reported large numbers of multidisciplinary staff, primarily consisting of RNs and critical care clinicians. Nearly all HLIUs (94%) required orientation training, although hours varied. CONCLUSIONS: Over a short period, HLIUs recruited and trained significant numbers of staff with little guidance. Costs of ongoing trainings are considerable, and it remains unclear how HLIUs will continue funding these activities.

RESUMEN

CONTEXT: US state public health departments played key roles in planning for and responding to confirmed and suspected cases of Ebola virus disease (EVD) during the 2014-2016 outbreak, including designating select hospitals as high-level isolation units (HLIUs) for EVD treatment in conjunction with the Centers for Disease Control and Prevention. OBJECTIVE: To identify existing guidelines and perspectives of state health departments pertaining to the management and transport of patients with EVD and other highly hazardous communicable diseases (HHCDs). DESIGN: An electronic 8-question survey with subquestions was administered as a fillable PDF. SETTING: The survey was distributed to publicly accessible e-mails of state health department employees. PARTICIPANTS: State epidemiologists, emergency preparedness directors, or chief medical officers from each of the 50 states and the District of Columbia were contacted; a representative from 36 states and the District of Columbia responded (73%). MAIN OUTCOME MEASURES: Descriptive statistics were used to identify the proportion of state health departments with various existing protocols. RESULTS: A majority of states reported that they would prefer patients confirmed with viral hemorrhagic fevers (eg, EVD, Marburg fever) and smallpox be transported to an HLIU for treatment rather than remain at the initial hospital of diagnosis. While most (89%) states had written guidelines for the safe transportation of patients with HHCDs, only 6 (16%) had written protocols for the management of accidents or other travel disruptions that may occur during HHCD transport within the state. Twenty-two state health departments (59%) had operationally exercised transport of a patient to an HLIU. CONCLUSIONS: Nearly half of states in the United States lack an HLIU, yet most prefer to have patients with HHCDs treated in high-level isolation. Recent budget cuts and uncertainty of future funding threaten the abilities of health departments to devote the necessary resources and staff to prepare for and deliver the desired care to HHCD cases. The lack of HLIUs in some states may complicate transport to a geographically proximate HLIU. Moreover, limited guidance on diseases that warrant high-level isolation may cause disagreement in HHCD patient placement between health departments, diagnosing facilities, and HLIUs.

RESUMEN

To identify barriers to maintaining and applying capabilities of US high-level isolation units (HLIUs) used during the Ebola virus disease outbreak, during 2016 we surveyed HLIUs. HLIUs identified sustainability challenges and reported the highly infectious diseases they would treat. HLIUs expended substantial resources in development but must strategize models of sustainability to maintain readiness.

RESUMEN

PURPOSE: A United States industry-specific gap analysis survey of the death care sector-which comprises organizations and businesses affiliated with the funeral industry and the handling of human remains- was developed, the results analyzed, and training and education needs in relation to highly infectious disease mitigation and management were explored in an effort to identify where occupational health and safety can be enhanced in this worker population. METHODS: Collaborating national death care organizations distributed the 47-question electronic survey. N = 424 surveys were initiated and results recorded. The survey collected death care sector-specific information pertaining to the comfortability and willingness to handle highly infectious remains; perceptions of readiness, current policies and procedures in place to address highly infectious diseases; current highly infectious disease training levels, available resources, and personal protective equipment. RESULTS: One-third of respondents have been trained on how to manage highly infectious remains. There was a discrepancy between Supervisor/Management and Employee/Worker perceptions on employees' willingness and comfortability to manage potentially highly infectious remains. More than 40% of respondents did not know the correct routes of transmission for viral hemorrhagic fevers. CONCLUSIONS: Results suggest death care workers could benefit from increasing up-to-date industry-specific training and education on highly infectious disease risk mitigation and management. Professional death care sector organizations are positioned to disseminate information, training, and best practices.

RESUMEN

An ultraviolet germicidal irradiation (UVGI) generator (the TORCH, ClorDiSys Solutions, Inc.) was used to compare the disinfection of surface coupons (plastic from a bedrail, stainless steel, and chrome-plated light switch cover) in a hospital room with walls coated with ultraviolet (UV)-reflective paint (Lumacept) or standard paint. Each surface coupon was inoculated with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus faecalis (VRE), placed at 6 different sites within a hospital room coated with UV-reflective paint or standard paint, and treated by 10 min UVC exposure (UVC dose of 0-688 mJ/cm2 between sites with standard paint and 0-553 mJ/cm2 with UV-reflective paint) in 8 total trials. Aggregated MRSA concentrations on plastic bedrail surface coupons were reduced on average by 3.0 log10 (1.8 log10 Geometric Standard Deviation [GSD]) with standard paint and 4.3 log10 (1.3 log10 GSD) with UV-reflective paint (p = 0.0005) with no significant reduction differences between paints on stainless steel and chrome. Average VRE concentrations were reduced by ≥4.9 log10 (<1.2 log10 GSD) on all surface types with UV-reflective paint and ≤4.1 log10 (<1.7 log10 GSD) with standard paint (p < 0.05). At 5 aggregated sites directly exposed to UVC light, MRSA concentrations on average were reduced by 5.2 log10 (1.4 log10 GSD) with standard paint and 5.1 log10 (1.2 log10 GSD) with UV-reflective paint (p = 0.017) and VRE by 4.4 log10 (1.4 log10 GSD) with standard paint and 5.3 log10 (1.1 log10 GSD) with UV-reflective paint (p < 0.0001). At one indirectly exposed site on the opposite side of the hospital bed from the UVGI generator, MRSA concentrations on average were reduced by 1.3 log10 (1.7 log10 GSD) with standard paint and 4.7 log10 (1.3 log10 GSD) with UV-reflective paint (p < 0.0001) and VRE by 1.2 log10 (1.5 log10 GSD) with standard paint and 4.6 log10 (1.1 log10 GSD) with UV-reflective paint (p < 0.0001). Coating hospital room walls with UV-reflective paint enhanced UVGI disinfection of nosocomial bacteria on various surfaces compared to standard paint, particularly at a surface placement site indirectly exposed to UVC light.

RESUMEN

Fifty-five hospitals in the United States have been designated Ebola treatment centers (ETCs) by their state and local health authorities. Designated ETCs must have appropriate plans to manage a patient with confirmed Ebola virus disease (EVD) for the full duration of illness and must have these plans assessed through a CDC site visit conducted by an interdisciplinary team of subject matter experts. This study determined the clinical laboratory capabilities of these ETCs. ETCs were electronically surveyed on clinical laboratory characteristics. Survey responses were returned from 47 ETCs (85%). Forty-one (87%) of the ETCs planned to provide some laboratory support (e.g., point-of-care [POC] testing) within the room of the isolated patient. Forty-four (94%) ETCs indicated that their hospital would also provide clinical laboratory support for patient care. Twenty-two (50%) of these ETC clinical laboratories had biosafety level 3 (BSL-3) containment. Of all respondents, 34 (72%) were supported by their jurisdictional public health laboratory (PHL), all of which had available BSL-3 laboratories. Overall, 40 of 44 (91%) ETCs reported BSL-3 laboratory support via their clinical laboratory and/or PHL. This survey provided a snapshot of the laboratory support for designated U.S. ETCs. ETCs have approached high-level isolation critical care with laboratory support in close proximity to the patient room and by distributing laboratory support among laboratory resources. Experts might review safety considerations for these laboratory testing/diagnostic activities that are novel in the context of biocontainment care.

RESUMEN

Reclaiming municipal wastewater for agricultural, environmental, and industrial purposes is increasing in the United States to combat dwindling freshwater supplies. However, there is a lack of data regarding the microbial quality of reclaimed water. In particular, no previous studies have evaluated the occurrence of vancomycin-resistant enterococci (VRE) in reclaimed water used at spray irrigation sites in the United States. To address this knowledge gap, we investigated the occurrence, concentration, and antimicrobial resistance patterns of VRE and vancomycin-susceptible enterococci at three U.S. spray irrigation sites that use reclaimed water. We collected 48 reclaimed water samples from one Mid-Atlantic and two Midwest spray irrigation sites, as well as their respective wastewater treatment plants, in 2009 and 2010. Samples were analyzed for total enterococci and VRE using standard membrane filtration. Isolates were purified and then confirmed using biochemical tests and PCR. Antimicrobial susceptibility testing was conducted using the Sensititre® microbroth dilution system. Data were analyzed by two-sample proportion tests and one-way analysis of variance. We detected total enterococci and VRE in 71% (34/48) and 4% (2/48) of reclaimed water samples, respectively. Enterococcus faecalis was the most common species identified. At the Mid-Atlantic spray irrigation site, UV radiation decreased total enterococci to undetectable levels; however, subsequent storage in an open-air pond at this site resulted in increased concentrations of enterococci. E. faecalis isolates recovered from the Mid-Atlantic spray irrigation site expressed intrinsic resistance to quinupristin/dalfopristin; however, non-E. faecalis isolates expressed resistance to quinupristin/dalfopristin (52% of isolates), vancomycin (4%), tetracycline (13%), penicillin (4%) and ciprofloxacin (17%). Our findings show that VRE are present in low numbers in reclaimed water at point-of-use at the sampled spray irrigation sites; however, resistance to other antimicrobial classes is more prevalent, particularly among non-E. faecalis isolates.

RESUMEN

This secondary analysis from a larger mixed methods study with a sequential explanatory design investigates the clinical challenges for nurses providing patient care, in an airborne and contact isolation room, while using a computer on wheels for medication administration in a simulated setting. Registered nurses, who regularly work in clinical care at the patient bedside, were recruited as study participants in the simulation and debriefing experience. A live volunteer acted as the standardized patient who needed assessment and intravenous pain medication. The simulation was video recorded in a typical hospital room to observe participating nurses conducting patient care in an airborne and contact isolation situation. Participants then reviewed their performance with study personnel in a formal, audio-recorded debriefing. Isolation behaviors were scored by an expert panel, and the debriefing sessions were analyzed. Considerable variation was found in behaviors related to using a computer on wheels while caring for a patient in isolation. Currently, no nursing care guidelines exist on the use of computers on wheels in an airborne and contact isolation room. Specific education is needed on nursing care processes for the proper disinfection of computers on wheels and the reduction of the potential for disease transmission from environmental contamination.

RESUMEN

Zoonotic transmission of influenza A virus (IAV) between swine and workers in swine production facilities may play a role in the emergence of novel influenza strains with pandemic potential. Guidelines to prevent transmission of influenza to swine workers have been developed but there is a need for evidence-based decision-making about protective measures such as respiratory protection. A mathematical model was applied to estimate the risk of occupational IAV exposure to swine workers by contact and airborne transmission, and to evaluate the use of respirators to reduce transmission. The Markov model was used to simulate the transport and exposure of workers to IAV in a swine facility. A dose-response function was used to estimate the risk of infection. This approach is similar to methods previously used to estimate the risk of infection in human health care settings. This study uses concentration of virus in air from field measurements collected during outbreaks of influenza in commercial swine facilities, and analyzed by polymerase chain reaction. It was found that spending 25 min working in a barn during an influenza outbreak in a swine herd could be sufficient to cause zoonotic infection in a worker. However, this risk estimate was sensitive to estimates of viral infectivity to humans. Wearing an excellent fitting N95 respirator reduced this risk, but with high aerosol levels the predicted risk of infection remained high under certain assumptions. The results of this analysis indicate that under the conditions studied, swine workers are at risk of zoonotic influenza infection. The use of an N95 respirator could reduce such risk. These findings have implications for risk assessment and preventive programs targeting swine workers. The exact level of risk remains uncertain, since our model may have overestimated the viability or infectivity of IAV. Additionally, the potential for partial immunity in swine workers associated with repeated low-dose exposures or from previous infection with other influenza strains was not considered. Further studies should explore these uncertainties.

RESUMEN

The estimated 721,800 hospital acquired infections per year in the United States have necessitated development of novel environmental decontamination technologies such as ultraviolet germicidal irradiation (UVGI). This study evaluated the efficacy of a novel, portable UVGI generator (the TORCH, ChlorDiSys Solutions, Inc., Lebanon, NJ) to disinfect surface coupons composed of plastic from a bedrail, stainless steel, chrome-plated light switch cover, and a porcelain tile that were inoculated with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus faecalis (VRE). Each surface type was placed at 6 different sites within a hospital room and treated by 10-min ultraviolet-C (UVC) exposures using the TORCH with doses ranging from 0-688 mJ/cm(2) between sites. Organism reductions were compared with untreated surface coupons as controls. Overall, UVGI significantly reduced MRSA by an average of 4.6 log10 (GSD: 1.7 log10, 77% inactivation, p < 0.0001) and VRE by an average of 3.9 log10 (GSD: 1.7 log10, 65% inactivation, p < 0.0001). MRSA on bedrail was reduced significantly (p < 0.0001) less than on other surfaces, while VRE was reduced significantly less on chrome (p = 0.0004) and stainless steel (p = 0.0012) than porcelain tile. Organisms out of direct line of sight of the UVC generator were reduced significantly less (p < 0.0001) than those directly in line of sight. UVGI was found an effective method to inactivate nosocomial pathogens on surfaces evaluated within the hospital environment in direct line of sight of UVGI treatment with variation between organism and surface types.

RESUMEN

To assess the behavior and precautions that swine workers take during suspected influenza outbreaks in swine, six commercial swine farms in the Midwest U.S. region were visited when influenza outbreaks were suspected in herds during the fall/winter of 2012-2013. Use of personal protective equipment (PPE) and type of task performed by swine workers were recorded based on farm representative reports. Between one to two workers were working on the day of each visit and spent approximately 25 minutes performing work-related tasks that placed them in close contact with the swine. The most common tasks reported were walking the aisles (27%), handling pigs (21%), and handling equipment (21%). The most common PPE were boots (100%), heavy rubber gloves (75%), and dedicated nondisposable clothing (74%). Use of N95 respirators was reported at three farms. Hand hygiene practices were common in most of the farms, but reportedly performed for only 20% to 25% of tasks.
