A unified personal protective equipment ensemble for clinical response to possible high consequence infectious diseases: A consensus document on behalf of the HCID programme

Clinical Management of Hospitalized Patients With High-Consequence Infectious Diseases in England

Infectious disease physicians in England have been diagnosing and managing occasional cases of viral hemorrhagic fever since 1971, including the United Kingdom's first case of Ebola virus disease in 1976. Specialist isolation facilities to provide safe and effective care have been present since that time. Following the emergence of Middle East respiratory syndrome (MERS) in 2012, and the avian influenza A (H7N9) outbreak in 2013, and the 2014-2016 Ebola virus disease outbreak in West Africa, clinical and public health preparedness and response pathways in England have been strengthened for these types of diseases, now called high-consequence infectious diseases (HCIDs). The HCID program, led by NHS England and Public Health England between 2016 and 2018, helped to deliver these enhancements, which have since been used on multiple occasions for new UK cases and outbreaks of MERS, mpox, avian influenza, and Lassa fever. Additionally, HCID pathways were activated for COVID-19 during the first 3 months of 2020, before the pandemic had been declared and little was known about COVID-19 but HCID status had been assigned temporarily to COVID-19 as a precaution. The HCID program also led to the commissioning of a network of new airborne HCID treatment centers in England, to supplement the existing network of contact HCID treatment centers, which includes the United Kingdom's only 2 high-level isolation units. In this case study, the authors describe the airborne and contact HCID treatment center networks in England, including their formation and structures, their approach to safe and effective clinical management of patients with HCIDs in the United Kingdom, and challenges they may face going forward.

Improving Safety and Comfort of Healthcare Workers Caring for Patients With High-Consequence Infectious Diseases in a High-Level Isolation Unit Using Innovative Approaches

Patients with high-consequence infectious diseases (HCIDs) require high-quality care by specially trained staff in a high-level isolation unit (HLIU) that follows strict infection prevention and control (IPC) measures. Caring for patients with (suspected) HCID is challenging, mainly because of the strict personal protective equipment (PPE) and IPC protocols healthcare workers (HCW) must adhere to for protection. The Radboud University Medical Center, located in Nijmegen, the Netherlands, has been a dedicated HLIU facility since 2008. A newly built HLIU opened in May 2022, and encouraged us to review the existing PPE selection, IPC protocols, and HCID training program to improve safety and comfort for HCWs working in the HLIU. Based on a systematic search through (inter)national HCID PPE guidelines and semistructured interviews with end users, we selected an improved, more comfortable set of PPE. Additionally, we developed a more concise and easier-to-use patient care process flow and implemented a new teaching strategy. The new way of working was tested in October 2022 when the first 2 patients with suspected HCID were admitted to our unit. We used surveys to evaluate the experiences of HCWs involved in this care to further improve the workflow of the unit. When optimizing safety and comfort for HCWs, it is important to consider (inter)national guidelines as well as user preferences. By systematically evaluating recent experiences of patient admission to the HLIU and then adjusting protocols and training, we can ensure that the quality of provided healthcare and the safety of HCWs working in the HLIU remains high.

High-consequence infectious diseases: the conception and development of a multi-disciplinary, interprofessional simulation training programme

BACKGROUND

High-consequence infectious diseases (HCIDs) represent a group of acute infectious diseases with the potential to impact healthcare systems and public health profoundly. Effective management requires a system-based strategy focused on early detection, initiation of infection prevention and control measures, and appropriate use of personal protective equipment (PPE). Inadequate training in the safe use of HCID PPE, and lack of familiarity with key processes such as HCID waste and spills management, exacerbates the risk posed to healthcare workers (HCWs). Enhanced training opportunities are required to ensure that staff are equipped with the necessary knowledge and capabilities to protect themselves from pathogen exposure and infection.

AIM

To create a bespoke interprofessional HCID simulation training programme.

METHODS

A detailed learning needs analysis was undertaken, which identified multiple areas amenable to educational intervention. A full-day HCID simulation programme was developed, providing HCWs the opportunity to practice and gain proficiency in various domains.

FINDINGS

Six interprofessional participants took part in the HCID simulation programme pilot. All six (100%) participants felt that the stated learning objectives had been achieved, and five and one participants found the programme to be extremely useful (83%) or very useful (17%), respectively. Following refinement based on pilot feedback, a further six courses have been run for 38 participants, of whom 97% found the programme to be extremely useful or very useful.

CONCLUSION

The development of a training intervention in the low-frequency, high-risk field of HCIDs had a positive impact. Given the disproportionate impact on HCWs at times of HCID outbreaks, more investment is needed to keep the workforce upskilled.

Preparing the Frontlines: Delivering Special Pathogen Training to Maryland Hospital Staff

Healthcare workers (HCWs) at community hospitals, also known as frontline hospitals (FLHs), may encounter patients with possible infectious diseases, including those caused by high-consequence pathogens such as Zaire ebolavirus. We created and piloted a 1-day, in-person, didactic and skills training program to determine the feasibility and acceptability of implementing an educational program to enhance the knowledge and skills needed to respond when a patient with a potential high-consequence pathogen presents to an FLH. The Maryland Department of Health queried all 104 state FLHs to identify their interest in participating in the pilot training program. HCWs from 12 (75%) of the 16 interested FLHs participated in the program before it was interrupted by the COVID-19 pandemic. In addition to pathogen-specific training based on the Identify, Isolate, and Inform framework, we provided skills training in the proper use of personal protective equipment, spill cleanup, and removal of an incapacitated HCW from an isolation area. We conducted a paired pretraining and posttraining knowledge assessment and measured a significant learning gain among 135 participants (2-tailed t test, P<.05). Over 95% of the participants reported that the training was relevant to their daily work and the clinical simulations and reference material were useful and appropriate for their learning level. Findings from this pilot program demonstrated the feasibility and acceptability of a 1-day combined didactic and skills training program focused on high-consequence pathogens. We plan to reengage the original FLHs and add regional FLHs in an updated training effort based on our findings.

The PATH to PPE Mastery - Programme for Assessment and Training in HCID (High Consequence Infectious Diseases) PPE (Personal Protective Equipment), Mastery

Background

High Consequence Infectious Diseases (HCIDs), have the potential to cause pandemics and require particular focus for preparedness due to their high mortality rates. The application of Personal Protective Equipment (PPE) for HCIDs is complex and carries significant risk of Health Care Worker (HCW) contamination if done incorrectly. Previous reviews have reported a lack of information on the nature of training provided and the ideal timing of repeat training to best retain skills. Simulation Based Mastery Learning (SBML) is a methodology for skill acquisition which encompasses deliberate practice and repeated assessment until the learner achieves a pre-set Mastery standard. SBML has been demonstrated to improve competence, skill retention and patient outcomes in other clinical procedures. SBML has not been previously studied or utilised in HCID PPE training.

Aim

We aimed to increase the likelihood of safe clinical practice by evidencing that Lothian modified SBML for PPE effectively prepares our priority learners.

Methods

A quasi-experimental within group post-test design was used. Learners undertook a modified SBML programme which included two-hour asynchronous and two-hour synchronous components.

Findings

11 learners (10 infectious diseases registrars and 1 infectious diseases consultant) were enrolled in the programme with 8 completing all stages, all of whom achieved the Mastery passing standard. The resources were highly rated by learners with the exemplar videos of skills highlighted as particularly useful. Self-assessed preparedness for each skill increased following pre-learning and synchronous sessions.

Conclusion

Modified SBML can be used as an effective methodology for the training and assessment of HCWs in the donning and doffing of HCID PPE.

Validation of personal protective equipment ensembles, incorporating powered air-purifying respirators protected from contamination, for the care of patients with high-consequence infectious diseases

BACKGROUND

The UK High-Consequence Infectious Diseases (HCID) Network of high-level isolation units provides care for patients with contact- or airborne-transmissible highly infectious and highly dangerous diseases. In most HCID units, the healthcare workers (HCWs) wear personal protective equipment (PPE) ensembles incorporating a powered air-purifying respirator (PAPR) for head and respiratory protection. Some PAPRs have components worn outside/over other PPE, necessitating decontamination of re-usable elements. Two alternative PAPRs, with all re-usable elements worn under PPE, were trialled in this study.

AIM

To undertake scenario-based testing of PAPRs and PPE to determine usability, comfort and ability to remove contaminated PPE without personal cross-contamination.

METHODS

Trained healthcare volunteers (N=20) wearing PAPR/PPE ensembles were sprayed with ultraviolet fluorescent markers. They undertook exercises to mimic patient care, and subsequently, after doffing the contaminated PPE following an established protocol, any personal cross-contamination was visualized under ultraviolet light. Participants also completed a questionnaire to gauge how comfortable they found the PPE.

FINDINGS AND CONCLUSIONS

The ensembles were tested under extreme 'worst case scenario' conditions, augmented by physical and manual dexterity tests. Participating volunteers considered the exercise to be beneficial in terms of training and PPE evaluation. Data obtained, including feedback from questionnaires and doffing buddy observations, supported evidence-based decisions on the PAPR/PPE ensemble to be adopted by the HCID Network. One cross-contamination event was recorded in the ensemble chosen; this could be attributed to doffing error, and could therefore be eliminated with further practice.

Dermatologic problems associated with personal protective equipment in health-care workers managing COVID-19 patients

BACKGROUND

The safety of health-care workers (HCWs) during the COVID-19 pandemic is a major concern worldwide. Dermatological problems due to personal protective equipment are annoying issues. We aimed to evaluate dermatological adverse events following the use of these protections in HCWs managing COVID-19 patients.

MATERIALS AND METHODS

One hundred and fifty-six workers managing COVID-19 patients were enrolled in this cross-sectional study. We conducted face-to-face interviews to collect the data and focused mainly on protection type and mucocutaneous symptoms with new onset or exaggeration after this equipment.

RESULTS

Dermatological problems following protective equipment usage occurred mainly during the 1^st week (65.4%). The most common site of skin involvement was the nose (82.7%) and the most frequent visible complaints were the pressure effect and erythema on the nose in 80.8% and 57.7% of cases, respectively. There was a significant association between mask type and facial skin problems (P < 0.001). The main symptoms were itching (21.8% scalp, 39.1% face and body) and burning sensation (14.1% scalp, 23.7% face and body). Skin desquamation (37.2%) and dorsal hand dermatitis (41.66%) were significantly more frequent in atopic participants (P = 0.02 and P = 0.01, respectively). Hand involvement was significantly associated with frequency of hand washing (odds ratio = 1.97, 95% confidence interval = 1.04-3.74, P = 0.03).

CONCLUSION

We found that skin problems related to protective equipment were common and frequently located on the face mainly due to facial masks. These complications should be prevented by proper use of this equipment.

Characteristics Associated With Health Care Worker Knowledge and Confidence in Elastomeric Half-Mask Respirator Use

OBJECTIVE

This study evaluated health care workers' (HCWs') knowledge and confidence in using elastomeric half-mask respirator (EHMR) attributes known to influence usage.

METHODS

Health care workers were surveyed regarding their EHMR donning and doffing experience. Respondents were categorized into competency categories based on their scores. Category differences were analyzed using χ 2 and multiple logistic regression.

RESULTS

Seventy-two percent showed high levels of EHMR donning and doffing knowledge and confidence (mastery); however, 21% had greater confidence than knowledge (misinformed). Respiratory therapists had greater odds of mastery than other HCWs ( P < 0.05), whereas those working in medical/surgical and pediatric units had greater odds of doubt than other HCWs ( P < 0.01).

CONCLUSIONS

Although most HCWs show high knowledge and confidence with EHMR use, strategies to confirm respirator use competency may ensure greater HCWs protection.

A Qualitative Study of Factors Influencing Unsafe Work Behaviors Among Environmental Service Workers: Perspectives of Workers, and Safety Managers: The Case of Government Hospitals in Addis Ababa, Ethiopia

BACKGROUND

Environmental Service (EVS) is a term that refers to cleaning in healthcare facilities. EVS personnel are exposed to a variety of hazards, including physical, chemical, ergonomic, cognitive, and biological hazards that contribute to the development of diseases and disabilities. Recognizing the conditions that promote unsafe behavior is the first step in reducing such hazards. The purpose of this study was to (a) investigate the attitudes and perceptions of safety among employees and safety managers in Addis Ababa hospitals, and (b) figure out what factors inhibit healthy work behaviors.

METHODS

The data for this study was gathered using 2 qualitative data gathering methods: key informant interviews and individual in-depth interviews. About 25 personnel from 3 Coronavirus treatment hospitals were interviewed to understand more about the factors that make safe behavior challenging. The interviews were recorded, transcribed, and then translated into English. Open Code 4.02 was used for thematic analysis.

RESULTS

Poor safety management and supervision, a hazardous working environment, and employee perceptions, skills, and training levels were all identified as key factors in the preponderance of unsafe work behaviors among environmental service workers.

CONCLUSIONS

Different types of personal and environmental factors were reported to affect safe work behavior among environmental service personnel. Individual responsibility is vital in reducing or eliminating these risk factors for unsafe behaviors, but management's involvement in providing resources for safe work behavior is critical.

Is it a challenging task to work with personal protective equipment in a COVID-19 ICU: Findings from a hospital-based cross-sectional study from north India

Introduction

Amidst the coronavirus disease 2019 (COVID-19) pandemic, the use of personal protective equipment (PPE) is mandatory for healthcare workers to remain protected against infection. The present study was undertaken to evaluate challenges faced by the healthcare workers while using level 3 PPE.

Methods

This hospital-based study was conducted among resident doctors selected by convenience sampling method using a pretested, semi-structured, self-administered questionnaire after getting informed consent from the participants to collect data on the somatic, psychological, and technical problems faced while working in PPE. Bivariate and multivariable logistic regression was done between outcome variables and other independent variables to check for the association.

Results

Of the total, 252 resident doctors completed the survey, their age ranged from 22 to 36 years with 140 (55.6%) males and 112 (44.4%) females. One-twenty-nine (51.2%) residents were trained to work in ICU, 73 (29%) participants used PPE ≤10 times and the rest 179 (71%) used PPE more than 10 times. The difficulties faced were as follows: visual impairment (n = 244, 96.8%), headache (n = 226, 89.6%), breathing difficulty (n = 216, 85.7%), hearing impairment (n = 201, 79.8%), sweating (n = 242, 96%), and fear of being infected (n = 156,61.9%). Two-thirty-six (93.6%) participants felt that overall work quality reduced due to PPE. Headache, hunger, urge to micturate, anxiety, sleep disturbances, and need to change the timing of medication or diet were higher with increased duration of work with PPE.

Conclusion

A longer duration of work is associated with headache, hunger, anxiety, and sleep disturbances. More research has to be done to improve the PPE to reduce problems like visual impairment, skin irritation, sweating, and breathing difficulty.

A Simulation-Based Failure Mode Analysis of SARS-CoV-2 Infection Control and Prevention in Emergency Departments

BACKGROUND

Severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19)] outbreak has been declared a global pandemic by the World Health Organization. The COVID-19 pandemic has highlighted problems of sustainable infection prevention and control measures worldwide, particularly the emerging issues with an insufficient supply of personal protective equipment. The aim of this study was to provide an action plan for mitigation of occupational hazards and nosocomial spread of SARS-CoV-2 through a failure mode analysis based on observations during in situ simulations.

METHODS

A multicenter, cross-sectional, observational, simulation-based study was performed in Latvia from March 2 to 26, 2020. This study was conducted at 7 hospitals affiliated with Riga Stradiņš University. The presentation of a COVID-19 patient was simulated with an in situ simulations, followed by a structured debrief. Healthcare Failure Modes and Effects Analysis is a tool for conducting a systematic, proactive analysis of a process in which harm may occur. We used Healthcare Failure Modes and Effects Analysis to analyze performance gaps and systemic issues.

RESULTS

A total of 67 healthcare workers from 7 hospitals participated in the study (range = 4-17). A total of 32 observed failure modes were rated using a risk matrix. Twenty-seven failure modes (84.4%) were classified as either medium or high risk or were single-point weaknesses, hence evaluated for action type and action; 11 (40.7%) were related to organizational, 11 (40.7%) to individual, and 5 (18.5%) to environmental factors.

CONCLUSIONS

Simulation-based failure mode analysis helped us identify the risks related to the preparedness of the healthcare workers and emergency departments for the COVID-19 pandemic in Latvia. We believe that this approach can be implemented to assess and maintain readiness for the outbreaks of emerging infectious diseases in the future.

Personal protective equipment and doffing procedures in out-of-hospital practice: assessment with a contamination simulation

BACKGROUND

The use of personal protective equipment (PPE) by emergency medical services (EMS) providers requires specific attention, as it takes place in out-of-hospital unsecured settings. The aim of this study was to evaluate which PPE gown was less contaminating during doffing procedures in an EMS setting. Six well-trained healthcare worker (HCW) subjects tested 4 different gowns: (1) surgical gowns (SG), (2) full body coveralls (FBC), (3) self-made alternative PPEs (SMP), and (4) non-surgical isolation gowns (NSIG). An invisible tracer was sprayed on the gown after donning each subject. After doffing, each HCW was photographed under UV lights to show areas of fluorescent "contamination" on their clothes. The number, size, and intensity level of contaminated areas were noted, as well as observational deviation from the procedure and doffing time. In addition, the subjects were asked to take a questionnaire about their perception of the level of comfort, ease of doffing, and overall safety for each gown.

RESULTS

Despite a well-trained team of HCW subjects, contamination while doffing was observed with every type of PPE gown, and with each HCW subject. All body areas were contaminated at least once, except the face. Contamination was more frequent while doffing FBCs. On the other hand, the removal of SG was found to be the least contaminating. The mean doffing time was significantly shorter with SG 1:29 and longer with FBC 2:26 (p=0.005).

CONCLUSION

Results of this study converge towards the selection of surgical gowns over other types of PPE gowns, which met both contamination criteria as well as staff appreciation in this context. Specific attention should be paid to the legs and abdomino-pelvic areas. Additional protection such as protective trousers or aprons could be added.

Performance and impact of disposable and reusable respirators for healthcare workers during pandemic respiratory disease: a rapid evidence review

OBJECTIVES

To synthesise evidence concerning the range of filtering respirators suitable for patient care and guide the selection and use of different respirator types.

DESIGN

Comparative analysis of international standards for respirators and rapid review of their performance and impact in healthcare.

DATA SOURCES

Websites of international standards organisations, Medline and Embase, hand-searching of references and citations.

STUDY SELECTION

Studies of healthcare workers (including students) using disposable or reusable respirators with a range of designs. We examined respirator performance, clinician adherence and performance, comfort and impact, and perceptions of use.

RESULTS

We included standards from eight authorities across Europe, North and South America, Asia and Australasia and 39 research studies. There were four main findings. First, international standards for respirators apply across workplace settings and are broadly comparable across jurisdictions. Second, effective and safe respirator use depends on proper fitting and fit testing. Third, all respirator types carry a burden to the user of discomfort and interference with communication which may limit their safe use over long periods; studies suggest that they have little impact on specific clinical skills in the short term but there is limited evidence on the impact of prolonged wearing. Finally, some clinical activities, particularly chest compressions, reduce the performance of filtering facepiece respirators.

CONCLUSION

A wide range of respirator types and models is available for use in patient care during respiratory pandemics. Careful consideration of performance and impact of respirators is needed to maximise protection of healthcare workers and minimise disruption to care.

Provider Perceptions of a Humanizing Intervention for Health Care Workers-A Survey Study of PPE Portraits

CONTEXT

Reports from patients and health care workers dealing with coronavirus disease 2019 (COVID-19) underscore experiences of isolation and fear. Some of this experience results from the distancing effect of masks, gloves, and gowns known as personal protective equipment (PPE). One approach to bridging the divide created by PPE is the use of PPE portraits, postcard-sized pictures affixed to PPE.

OBJECTIVES

Our confidential electronic mail-based survey aimed to quantify provider attitudes toward PPE portraits.

METHODS

PPE portraits were piloted at an academic safety-net health system experiencing a COVID-19 patient surge during April-May 2020, necessitating use of full PPE for COVID-positive patients and surgical masks in all hospital settings. Our survey assessed staff exposure to PPE portraits, attitudes toward PPE portraits, and potential program expansion. For staff wearing PPE portraits, we also assessed perceptions of interactions with other staff and patients/families and impact on personal well-being. The University of Massachusetts Medical School's Institutional Review Board designated this as a quality improvement project (#H00020279).

RESULTS

More than half of survey respondents (n = 111 of 173; 64%) reported exposure to PPE portraits. Attitudes toward PPE portraits were positive overall, with agreement that PPE portraits were a good idea (89%), improved provider mood (79%), enhanced perception of team connection (72%), and more positive among those who reported exposure. Open-ended responses (n = 41) reinforced positive survey data and also raised concerns about infection control (n = 6), cost/logistics (n = 5), and provider vulnerability (n = 3).

CONCLUSION

Providers report that PPE portraits may represent a positive patient-centered idea that helps reassure patients, is well received by interdisciplinary staff, and may enhance patient and team interactions. Potential adaptations to address concerns include photo pins and donor/patient and family experience department support for costs.

Common Behaviors and Faults When Doffing Personal Protective Equipment for Patients With Serious Communicable Diseases

Background

The safe removal of personal protective equipment (PPE) can limit transmission of serious communicable diseases, but this process poses challenges to healthcare workers (HCWs).

Methods

We observed 41 HCWs across 4 Ebola treatment centers in Georgia doffing PPE for simulated patients with serious communicable diseases. Using human factors methodologies, we obtained the details, sequences, and durations of doffing steps; identified the ways each step can fail (failure modes [FMs]); quantified the riskiness of FMs; and characterized the workload of doffing steps.

Results

Eight doffing steps were common to all hospitals—removal of boot covers, gloves (outer and inner pairs), the outermost garment, the powered air purifying respirator (PAPR) hood, and the PAPR helmet assembly; repeated hand hygiene (eg, with hand sanitizer); and a final handwashing with soap and water. Across hospitals, we identified 256 FMs during the common doffing steps, 61 of which comprised 19 common FMs. Most of these common FMs were above average in their riskiness at each hospital. At all hospitals, hand hygiene, removal of the outermost garment, and removal of boot covers were above average in their overall riskiness. Measurements of workload revealed that doffing steps were often mentally demanding, and this facet of workload correlated most strongly with the effortfulness of a doffing step.

Conclusions

We systematically identified common points of concern in protocols for doffing high-level PPE. Addressing FMs related to hand hygiene and the removal of the outermost garment, boot covers, and PAPR hood could improve HCW safety when doffing high-level PPE.

We identified ways that doffing protocols for high-level personal protective equipment may fail to protect healthcare workers. Hand hygiene, removing the outermost garment, boot covers, and respirator hood harbored the greatest risk and failed in similar ways across different hospitals.

AEG-SEED position paper for the resumption of endoscopic activity after the peak phase of the COVID-19 pandemic

Introduction

The COVID-19 pandemic has led to the suspension of programmed activity in most of the Endoscopy Units in our environment. The aim of this document is to facilitate the resumption of elective endoscopic activity in an efficient and safe manner.

Material and methods

A series of questions considered to be of clinical and logistical relevance were formulated. In order to elaborate the answers, a structured bibliographic search was carried out in the main databases and the recommendations of the main Public Health and Digestive Endoscopy institutions were reviewed. The final recommendations were agreed upon through telematic means.

Results

A total of 33 recommendations were made. The main aspects discussed are: 1) Reassessment and prioritization of the indication, 2) Restructuring of spaces, schedules and health personnel, 3) Screening for infection, 4) Hygiene measures and personal protective equipment.

Conclusion

The AEG and SEED recommend restarting endoscopic activity in a phased, safe manner, adapted to local resources and the epidemiological situation of SARS-CoV-2 infection.

Personal protective equipment for viral hemorrhagic fevers

PURPOSE OF REVIEW

Viral hemorrhagic fevers (VHF) encompass many organisms that have caused sporadic outbreaks with high case fatality rates. This article reviews VHF with reported human-to-human transmission and describes updates about personal protective equipment (PPE) for healthcare personnel (HCP) and others. We summarize existing information about appropriate PPE use, training, and compliance for care of VHF patients in endemic and nonendemic countries, as well as addresses the challenges HCP experience when using PPE.

RECENT FINDINGS

PPE is essential in protecting HCP from exposure to disease-causing pathogens. Recent evidence shows that anyone involved in care, management, and transport of certain VHF patients must use elements of PPE as part of appropriate infection prevention and control (IPC) practices. Strict adherence to standard precautions has effectively interrupted human-to-human transmission of a number of VHF. However, unclear protocols, inconsistent training, climate challenges, and cultural sensitivities impede proper PPE use. Appropriate PPE use can drastically reduce the risk of HCP exposure to VHF.

SUMMARY

Infections caused by certain VHFs can be highly pathogenic and associated with significant morbidity and mortality. Though it is well documented that use of PPE and good IPC practices are critical to reducing transmission, little conclusive evidence exists about the ideal PPE ensemble or components. Concerns with comfort, compliance, training, and usability may impede proper PPE use. Basic PPE elements, used appropriately as part of stringent IPC, must always form the foundation of care for HCP-treating patients with VHF. More research is required to identify the ideal PPE ensemble for caring for VHF patients in various settings.

Doing Our Part to Conserve Resources: Determining Whether All Personal Protective Equipment Is Mandatory for Closed Reduction and Percutaneous Pinning of Supracondylar Humeral Fractures

BACKGROUND

Closed reduction and percutaneous pinning (CRPP) of supracondylar humeral fractures is one of the most common procedures performed in pediatric orthopaedics. The use of full, standard preparation and draping with standard personal protective equipment (PPE) may not be necessary during this procedure. This is of particular interest in the current climate as we face unprecedented PPE shortages due to the current COVID-19 pandemic.

METHODS

This is a retrospective chart review of 1,270 patients treated with CRPP of a supracondylar humeral fracture at 2 metropolitan pediatric centers by 10 fellowship-trained pediatric orthopaedic surgeons. One surgeon in the group did not wear a mask when performing CRPP of supracondylar humeral fractures, and multiple surgeons in the group utilized a semisterile preparation technique (no sterile gown or drapes). Infectious outcomes were compared between 2 groups: full sterile preparation and semisterile preparation. We additionally analyzed a subgroup of patients who had semisterile preparation without surgeon mask use. Hospital cost data were used to estimate annual cost savings with the adoption of the semisterile technique.

RESULTS

In this study, 1,270 patients who underwent CRPP of a supracondylar humeral fracture and met inclusion criteria were identified. There were 3 deep infections (0.24%). These infections all occurred in the group using full sterile preparation and surgical masks. No clinically relevant pin-track infections were noted. There were no known surgeon occupational exposures to bodily fluid. It is estimated that national adoption of this technique in the United States could save between 18,612 and 22,162 gowns and masks with costs savings of $3.7 million to $4.4 million annually.

CONCLUSIONS

We currently face critical shortages of PPE due to the COVID-19 pandemic. Data from this large series suggest that a semisterile technique during CRPP of supracondylar humeral fractures is a safe practice. We anticipate that this could preserve approximately 20,000 gowns and masks in the United States over the next year. Physicians are encouraged to reevaluate their daily practice to identify safe opportunities for resource preservation.

Graphene Modified Multifunctional Personal Protective Clothing

Personal protective clothing is intended to protect the wearer from various hazards (mechanical, biological, chemical, thermal, radiological, etc.) and inhospitable environmental conditions that may cause harm or even death. There are various types of personal protective clothing, manufactured with different materials based on hazards and end user requirements. Conventional protective clothing has impediments such as high weight, bulky nature, lack of mobility, heat stress, low heat dissipation, high physical stress, diminishing dexterity, diminishing scope of vision, lack of breathability, and reduced protection against pathogens and hazards. By virtue of the superlative properties of graphene, fabrics modified with this material can be an effective means to overcome these limitations and to improve properties such as mechanical strength, antibacterial activity, flame resistance, conductivity, and UV resistance. The limitations of conventional personal protective equipment are discussed, followed by necessary measures which might be taken to improve personal protective equipment (PPE), the unique properties of graphene, methods of graphene incorporation in fabrics, and the current research status and potential of graphene-modified performance textiles relevant to PPE.
