Demand For Personal Protective Equipment Research Articles

Optimizing COVID-19 medical waste management using goal and robust possibilistic programming

During the global Coronavirus Disease (COVID-19) pandemic, the exponential rise in Hazardous Medical Waste (HMW) due to increased demand for personal protective equipment and heightened medical requirements posed significant threats to public health. This study proposes an innovative approach using a reverse logistics supply chain network that comprehensively integrates sustainability factors (e.g., cost, working conditions, exposure risks, and environmental impact) to manage the risks associated with medical waste effectively amid the pandemic. This research focuses on employing a guideline-based allocation of medical waste to specific technologies, leveraging the Torabi-Hassini (TH), Lp-metric (Lebesgue metric), and Goal Attainment (GA) approaches and robust possibilistic programming to address uncertainties. A real-case study validates the proposed model, demonstrating its ability to balance multiple objectives by optimizing the flow among treatment centers and introducing new Temporary Treatment Centers (TTCs). Also, we analyze broad sensitivity through weights assigned to the objective functions to obtain Pareto solutions. The convexity of the Pareto front confirms the conflict among the objective functions. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach specifies that the Lp-metric approach outperforms the others, and the TH approach is regarded as the second rank. The study's findings highlight the model's efficacy and provide crucial managerial insights for health organization administrators in efficiently managing the HMW supply chain network.

Recycling facemasks into civil construction material to manage waste generated during COVID-19.

Growing plastic pollution in the context of COVID-19 has caused significant challenges, exacerbating this already out-of-control issue. The pandemic has considerably boosted the demand for personal protective equipment (PPE), such as facemasks and gloves, all over the globe, and mismanaging this growing plastic pollution has harmed the environment and wildlife significantly. To mitigate negative environmental impacts, it is necessary to develop and implement effective waste management strategies. This present study estimated the daily facemask generation throughout the pandemic in Iran based on the distribution of urban and rural populations and, likewise, the daily generation of hand gloves in the COVID-19 era and the amount of medical waste generated by COVID-19 patients were calculated. In the next step, the quantities of discarded facemasks dumped into the Caspian Sea, the Persian Gulf, and the Gulf of Oman from the coastal cities were determined. Finally, the innovative alternatives for repurposing discarded facemasks in civil construction materials such as concrete, pavement, and partition wall panel were discussed.

Recent Biotechnological Applications of Polyhydroxyalkanoates (PHA) in the Biomedical Sector-A Review.

Petroleum-derived plastics are materials of great importance for the contemporary lifestyle, and are widely used commercially because they are low cost, resistant, malleable, and weightless, in addition to their hydrophobic character. However, some factors that confer the qualities of these materials also cause problems, mainly environmental, associated with their use. The COVID-19 pandemic aggravated these impacts due to the high demand for personal protective equipment and the packaging sector. In this scenario, bioplastics are environmentally positive alternatives to these plastics due to their applicability in several areas ranging from packaging, to biomedicine, to agriculture. Polyhydroxyalkanoates (PHAs) are biodegradable biopolymers usually produced by microorganisms as an energy reserve. Their structural variability provides a wide range of applications, making them a viable option to replace polluting materials. PHAs can be applied in various biotechnology sectors, such as producing drug carriers and scaffolds for tissue engineering. This review aimed to survey works published in the last five years on the study and biotechnological application of PHAs in the biomedical sector, exploring the versatility and advantages of their use and helping to understand how to enhance their application.

Initial response to SARS-CoV-2 (COVID-19) outbreak in Sri Lanka; views of public health specialists through an International Health Regulations lens.

The COVID-19 pandemic affected Sri Lanka despite having developed an International Health Regulations (IHR) steering committee in 2016 and a national action plan for health security following the Joint External Evaluation in 2018. Many steps were taken to improve the disaster management skills of healthcare workers even before the COVID-19 outbreak. We interviewed seven public health specialists to obtain their views on the country's response to the pandemic. A thematic analysis was conducted, leading to the emergence of three major themes and seven subthemes. The major themes included health security preparedness; COVID-19 management; and effects of COVID-19. The subthemes were; preparedness prior to pandemic and gaps in the preparedness (under health security preparedness); dual burden for the curative sector, strategies to reduce transmission and barriers to managing COVID-19 (under COVID-19 management) and negative and positive effects of COVID-19 (under effects of COVID-19). When COVID-19 reached Sri Lanka, healthcare workers, border control authorities and those involved with infectious disease control were overwhelmed by the magnitude of the pandemic. Healthcare workers' hesitation to work amidst the pandemic due to fear of infection and possible transmission of infection to their families was a major issue; the demand for personal protective equipment by health workers when stocks were low was also a contributory factor. Lockdowns with curfew and quarantine at government regulated centers were implemented as necessary. Perceptions of the public including permitting healthcare workers to perform field public health services, logistical barriers and lack of human resources were a few of the barriers that were expressed. Some persons did not declare their symptoms, fearing that they would have to be quarantined. The pandemic severely affected the economy and Sri Lanka relied on donations and loans to overcome the situation. Pandemic also brought about innovative methods to maintain and upgrade health service provision. Individuals with non-communicable diseases received their regular medications through the post which reduced their risk of being infected by visiting hospitals. Improvement of laboratory services and quarantine services, a reduction of acute respiratory infections and diarrhoeal diseases, improved intersectoral coordination and public philanthropic response were other positive effects.

Capacity acquisition and PPE distribution planning during the COVID-19 pandemic

As demand for personal protective equipment (PPE) surged during the COVID-19 pandemic and healthcare facilities faced supply shortages, the availability and distribution of PPE, being critical in fighting the pandemic, required pooling resources from multiple sectors. We explore such a resource pooling problem and propose to build up capacity by acquiring distribution and storage capacity from private carriers in return for compensation. We present a capacity acquisition and PPE distribution planning model under sufficient supply to optimally acquire storage and distribution capacity from third parties to fulfill demand. We then consider insufficient supply and propose a priority-based model based on pandemic severity. Finally, we model uncertain demand through two-stage stochastic programming with recourse and solve it using Benders decomposition and sample average approximation. We build a test case for the province of Ontario, Canada and provide detailed analysis under varying supply and demand scenarios.

Optimization of pyrolysis process parameters for a higher yield of plastic oil with enhanced physicochemical properties derived from medical plastic wastes

After the COVID-19 pandemic, the demand for personal protective equipment (PPE) kits has increased substantially to ensure workplace health. As the majority of PPE kits are derived from plastic, the disposal of used PPE kits poses a significant risk to the environment and human health. Though some existing studies addressed the conversion of medical wastes into useful energy, none of the studies attempted to optimize the pyrolysis process parameters for a higher yield of pyrolysis oil extraction with improved physicochemical properties. Hence, in the present study, waste plastic oil (WPO) from PPE gowns was extracted using a pyrolysis process for engine applications to protect the environment and promote greener recycling. The pyrolysis process parameters such as reaction temperature (RTemp), reaction time (RTime), and catalyst concentration (CC) were optimized using a multi-response optimization tool for a higher yield of WPO with improved physicochemical qualities. The physicochemical properties of optimally produced WPO were compared with those of regular diesel (RD), and the elemental and functional groups were analyzed. The optimization result indicates that a RTemp of 403.2 °C, a RTime of 105.6 min, and a CC of 1.3 wt% produce the highest yield of WPO (81.2%) with exceptional physicochemical properties. The robustness of the proposed model was demonstrated by the confirmation experiment that validated the predicted output response values. Under optimal conditions, the physicochemical properties of derived WPO are comparable to those of RD, and the WPO's functional compounds assure its viability as a diesel fuel substitute.

Attaching protein-adsorbing silica particles to the surface of cotton substrates for bioaerosol capture including SARS-CoV-2

The novel coronavirus pandemic (COVID-19) has necessitated a global increase in the use of face masks to limit the airborne spread of the virus. The global demand for personal protective equipment has at times led to shortages of face masks for the public, therefore makeshift masks have become commonplace. The severe acute respiratory syndrome caused by coronavirus-2 (SARS-CoV-2) has a spherical particle size of ~97 nm. However, the airborne transmission of this virus requires the expulsion of droplets, typically ~0.6–500 µm in diameter (by coughing, sneezing, breathing, and talking). In this paper, we propose a face covering that has been designed to effectively capture SARS-CoV-2 whilst providing uncompromised comfort and breathability for the wearer. Herein, we describe a material approach that uses amorphous silica microspheres attached to cotton fibres to capture bioaerosols, including SARS CoV-2. This has been demonstrated for the capture of aerosolised proteins (cytochrome c, myoglobin, ubiquitin, bovine serum albumin) and aerosolised inactivated SARS CoV-2, showing average filtration efficiencies of ~93% with minimal impact on breathability.

Localisation of PPE manufacturing during COVID-19 (local manufacturing partnership and Kingsgate Clothing South Africa)

Learning outcomes • After working through the case and assignment questions, students will be able to do the following:• Identify the difference between core competencies and dynamic capabilities and how they make a difference in a crisis towards building an agile organisation.• Evaluate the support through a collaborative, temporary, trans-organisational system to local manufacturers to achieve agility and sustainability.• Realise the importance of clear expectations exchange and communication between partners to enhance collaboration, even in temporary structures in increasing agility and sustainability. Case overview/synopsis The COVID-19 pandemic and subsequent lockdowns created a crisis for South Africa and the President, Cyril Ramaphosa called for urgent collaboration between business, labour and government to meet the demand for locally produced Personal Protective Equipment (PPE) and medical devices. The case illustrates this response and collaboration between government, labour and business through a temporary newly formed structure, called Business for South Africa (B4SA). Ross Boyd, Head of the innovation work stream of B4SA which housed the local manufacturing partnership (LMP) was considering his dilemma of how to be agile in sustaining their support to the South African manufacturers even though the LMP was a temporary structure. The local manufacturers had to repurpose their production lines to produce local PPE and medical devices. How could the LMP support the South African manufacturers to sustain their agility in building capabilities during COVID-19? At the same time, Ahmed Dhai, the Group Executive of Operations of Kingsgate Clothing, which was benefiting from the support of the LMP, was reflecting on his leadership in taking decisions to repurpose production and increase capacity during COVID-19. Dhai was considering his dilemma of being agile during and beyond the COVID-19 pandemic. The case features several decisions taken by Kingsgate and offers students the opportunity to evaluate these decisions given the fluctuations in supply and demand of PPE and the leadership that Dhai demonstrated in how he communicated and dealt with his staff during the pandemic. Students could also give recommendations to Ross Boyd and Ahmed Dhai on how they could lead their organisations to be more agile during and beyond COVID-19. Complexity academic level The case study is suitable for MBA or MPhil level on Strategy courses. The case would also find good application in Organisational Behaviour and Leadership courses on Masters level and Executive Education programmes.

PPE Supply Optimization Under Risks of Disruption from the COVID-19 Pandemic

The COVID-19 pandemic has struck health service providers around the world with dire shortages, inflated prices, and volatile demand of personal protective equipment (PPE). This paper discusses supply chain resilience in the context of a Canadian provincial healthcare provider during the COVID-19 pandemic. A multi-period multi-objective mixed-integer programming model is presented for PPE supply planning under disruption risk. The deterministic formulation is extended to consider both two-stage and multi-stage uncertainty in the supply, price, and demand of PPE using stochastic programming (SP) and chance-constrained programming (CCP). The first objective is to minimize a risk measure of the stochastic total cost, either its Expected Value (EV) or its Value-at-Risk (VaR), and the second objective is to minimize the maximum shortage of any product in any time period. The $$\epsilon$$ -constraint method is used to generate sets of Pareto-optimal solutions and analyze the trade-off between these two competing objectives. Numerical experiments are conducted to analyze the efficacy of emergency inventory and increased inventory levels as risk mitigation strategies. We consider uncertainty scenarios based on plausible and actual pandemic trajectories seen around the world during the COVID-19 pandemic including single-wave, two-wave, and exponential growth.

Design and fabrication of a biodegradable face shield by using cleaner technologies for the protection of direct splash and airborne pathogens during the COVID-19 pandemic

Due to global supply chain disruptions and high demand for personal protective equipment (PPE), the rapidly expanding COVID-19 crisis left millions of front-line fighters unprotected. The disposal of PPE in the environment caused significant environmental pollution. Hence, indigenous initiatives have been taken to fabricate antiviral and biodegradable face shields with the help of neoteric and cleaner technologies. This paper describes a novel endeavor to design, manufacture, and performance analysis of a face shield made by plastic injection molding and LASER Cutting. Because of the requirement of permanent wear, the face shield's ergonomic design is considered low weight and easy head fixation, alongside high production ability. Here, face shield frames are made with lightweight, biodegradable plastic called Poly Lactic Acid (PLA), whereas an optical grade PLA sheet is used as the visor for better clarity. Visors PLA Sheet is coated with Nano-Silver disinfectant spray to incorporate antiviral properties to the Faceshield. Partially circumferential adjustable elastic straps are used for comfortable head fixation. To evaluate the product, clinical fit tests along with statistical survey were conducted, and the feedback from the end-users on comfort (41% Excellent, 30% Good, 26% Average and 3% Poor), clear view (33% Excellent, 38% Good, 24% Average, and 5% Poor), design features (43% Excellent, 35% Good, and 22% Average), simplicity of installation and disassembly (29% Excellent, 33% Good, and 38% Average), and ease of wearing/removing (45% Excellent, 40% Good, and 15%Average) are encouraging.

PPE needs in the United States during the COVID‐19 pandemic: An analysis using the GetUsPPE online platform

AbstractThe United States is heavily impacted by the COVID‐19 pandemic starting in 2020. Demand for personal protective equipment (PPE) domestically, along with global surge in demand for PPE during the pandemic, overwhelmed supply chains, leading to acute PPE shortages. This article analyzes the PPE supply and demand in the United States by employing data collected by GetUsPPE, a data hub used throughout the pandemic to coordinate support efforts, including connecting facilities in need of PPE with donated supplies. In this article, PPE requests were examined by facility type (acute vs. non‐acute care), geographic location, and PPE type. The research team observed that PPE demand was dispersed across the United States. In the beginning of the pandemic when demand was highest, most requesting facilities self‐reported as acute care facilities, whereas non‐acute care facilities predominated after June 2020. Additionally, the demand for respirators, disinfecting wipes, gowns, face shields, and surgical masks peaked in response to the first, second, and third waves of COVID‐19. This analysis can be utilized in the future to optimize the tracking of PPE shortages and relief efforts.

Establishing local manufacture of PPE for healthcare workers in the time of a global pandemic

A face shield is a secondary personal protective equipment (PPE) for healthcare workers (HCW). Worn with the appropriate face masks/respirators, it provides short term barrier protection against potentially infectious droplet particles. Coronavirus disease 2019 (COVID-19) caused a spike in demand for PPE, leading to a shortage and risking the safety of HCW. Transport restrictions further challenged the existing PPE supply chain which has been reliant on overseas-based manufacturers. Despite the urgency in demand, PPE must be properly tested for functionality and quality. We describe the establishment of local face shields manufacture in Western Australia to ensure adequate PPE for HCW. Ten thousand face shields for general use (standard) and for ear, nose and throat (ENT) specialist use were produced. Materials and design considerations are described, and the face shields were vigorously tested to the relevant Standards to ensure their effectiveness as a protective barrier, including splash and impact resistance. Comparative testing with traditional and other novel face shields was also undertaken. Therapeutic Goods Administration (TGA) licence was obtained to manufacture and supply the face shields as a Class I medical device. The swiftness of process is a credit to collaboration from industry, academia and healthcare.

Influence of COVID-19 to Personal Protection Equipment

In the article, we explore the impacts of COVID-19 on the personal protective equipment industry which is mainly focused on producing masks, glasses, protective suits, and disinfectants. Beginning in 2020, the epidemic spread to the whole world and lead everyone to live in the fear. COVID-19 influences every aspect of people's life such as work and life. When we make plans, we always consider the spreading and cases. In order to avoid the inconvenience to people and reduce the risk of being infected, personal protective equipment plays a major role in protecting people. We are required to wear masks and clean our hands when we enter some shopping malls or transportation. The demand for personal protective equipment dramatically increased as we pay high attention to our health. COVID-19 sped up the industry to meet the huge market demand. We use a case study and analyze data from 3M, creating graphs and tables to show the overall trend. Actually, 3M gained profits from the pandemic from our research. By analyzing, we can learn more about the influence of COVID-19 in a certain industry and further influence people's daily life.

A Data-Driven Approach to Allocating Personal Protective Equipment During the COVID-19 Pandemic in King County, Washington.

From the Field is a semiregular column that provides insight into the experiences of local, county, or state health professionals on the frontlines of health emergencies. National Association of County and City Health Officials members share the challenges faced and the solutions developed as they prepared for and responded to disasters, epidemics, and other major health issues. The aim of sharing these practical experiences is to provide other public health champions with the information and tools they need to help keep their communities safe even in extreme situations. The COVID-19 pandemic created an extraordinarily high demand for personal protective equipment (PPE). Acute need and supply chain disruptions made hospitals, emergency medical services, and other critical care agencies particularly vulnerable to PPE shortages. In March 2020, King County, Washington, developed computational tools, operating procedures, and data visualizations to fulfill its responsibilities to prioritize, allocate, and distribute scarce PPE equitably and efficiently during a public health emergency. King County distributed over 1.6 million gowns, 22 million gloves, 3.9 million surgical masks, and 1.5 million N95 respirators (among other items) during its PPE distribution mission. An algorithm processed resource requests from the community, with respect to available inventory, emergency allocation policies, prioritization constraints, estimated PPE use rates, agency-specific needs, and other parameters. With these inputs and constraints, the requests were translated into instructions for fulfillment and delivery and several tabular and graphical data visualizations were produced for quality assurance and transparency. Access to timely, relevant, and stable data was a constant challenge, and constraints invariably changed as the emergency response unfolded. King County's PPE distribution mission provides a useful case study in how to develop a scalable and data-driven approach to resource allocation and distribution under emergency response conditions.

Insight into the microplastics release from disposable face mask: Simulated environment and removal strategy

The fight against the COVID-19 epidemic significantly raises the global demand for personal protective equipment, especially disposable face masks (DFMs). The discarded DFMs may become a potential source of microplastics (MPs), which has attracted much attention. In this work, we identified the detailed source of MPs released from DFMs with laser direct infrared spectroscopy. Polypropylene (PP) and polyurethane (PU) accounted for 24.5% and 57.1% of released MPs, respectively. The melt-blown fabric was a dominant MPs source, however, previous studies underestimated the contribution of mask rope. The captured polyethylene terephthalate (PET), polyamide (PA), polyethylene (PE), and polystyrene (PS) in airborne only shared 18.4% of released MPs. To deepen the understanding of MPs release from medical mask into the aquatic environment, we investigated the effects of environmental factors on MPs release. Based on regression analysis, the effects of temperature, incubation time, and wearing time significantly affect the release of MPs. Besides, acidity, alkalinity, sodium chloride, and humic acid also contributed to the MPs release through corroding, swelling, or repulsion of fibers. Based on the exposure of medical mask to simulated environments, the number of released MPs followed the order: seawater > simulated gut-fluid > freshwater > pure water. Considering the risk of MPs released from DFMs to the environment, we innovatively established a novel flotation removal system combined with cocoamidopropyl betaine, achieving 86% removal efficiency of MPs in water. This work shed the light on the MPs release from DFMs and proposed a removal strategy for the control of MPs pollution.

Experimental and numerical evaluation of a new visor concept with aerodynamic sealing to protect medical professionals from contaminated droplets and aerosols.

The fast spreading of the SARS‐CoV‐2 virus led to a significant increase in the demand for personal protective equipment (PPE). Healthcare professionals, mainly dentists, work near the patients, increasing their risk of infection. This paper investigates the effectiveness of an air‐curtain sealing effect in a newly designed visor developed to reduce the risk of contracting a respiratory infection. This PPE was developed by computational fluid dynamics (CFD) modeling. CFD results show that the aerodynamic sealing in this PPE device effectively protects the user's face by 43% from a contaminated environment. The experiments considered two different tests: one using a tracer gas (CO2) to simulate a gaseous contaminant inside and outside the PPE face shield and a second test using smoke to simulate aerosol transport and evaluate the PPE efficiency. The particle concentration within the aerodynamically sealed PPE was evaluated and compared with the protection efficiency of other PPE. Results show similar protection levels for particles in the 1–5 μm range between the prototype and a KN95 respirator. The combined use of this novel PPE with aerodynamic sealing and a physical mask (KN95 or surgical) produced protection efficiency values within the range of 57%–70% for particles greater than 0.5 μm. This study reveals the potential of using an air curtain combined with a face shield to reduce the risks from contaminated environments.

3D Printed Medical Accessories Using FDM Process for COVID-19 Virus

The sudden spike in the Covid-19 pandemic cases around the world caused an urgent demand for Personal Protective Equipment (PPE), such as N95 face mask, face shield, ventilator valve, and non-contact door hook. The current situation requires a huge cost involvement and hard to solve the huge demand in a short period by using the traditional fabrication process. Therefore, the three-dimensional (3D) printing technology emerged as a suitable alternative to produce cost-effective production methods for these components. The present research work focuses on the design, types of filament material, and 3D printing process to print the required PPE kits, which facilitates to reduce the economic cost, environmentally hazardous, and failure of the product (reusable). Overall the initial investment needed for the 3D printing technology to print the polymer medical accessories is reduced and the material can be reused after appropriate treatment.

A legal-realist assessment of the Zimbabwean correctional system response to COVID-19 during state disaster measures

PurposeThe first prison system case in Zimbabwe was notified in July 2020 shortly after State declaration of disaster. A legal-realist assessment was conducted of the Zimbabwean correctional system response to COVID-19 during state disaster measures, with a focus on assessing right to health, infectious disease mitigation and the extent to which minimum state obligations complied with human and health rights standards.Design/methodology/approachThe Zimbabwean correctional system operations during COVID-19 disaster measures are scrutinized using a range of international, African and domestic human rights instruments in relation to the right to health of prisoners. This study focused particularly on standards of care, environmental conditions of detention and right of access to health care.FindingsSystemic poor standards of detention are observed, where prisoners experience power outages, water shortages and a lack of access to clean drinking water and water for ablution purposes, a severe lack of safe space and adequate ventilation, poor quality food and malnutrition and a lack of sufficient supply of food, medicines, clothing and bedding. Whilst access to health care of prisoners in Zimbabwe has greatly improved in recent times, the standard of care was severely stretched during COVID-19 due to lack of government resourcing and reliance on non-governmental organisation and faith-based organisations to support demand for personal protective equipment, disinfection products and medicines.Originality/valuePrison conditions in Zimbabwe are conducive to chronic ill health and the spread of many transmissible diseases, not limited to COVID-19. The developed legal-realist account considers whether Zimbabwe had a culture of respect for the rule of law pertinent to human and health rights of those detained during COVID-19 disaster measures, and whether minimum standards of care were upheld.

Safety-Stock: Predicting the demand for supplies in Brazilian hospitals during the COVID-19 pandemic

Many challenges lie ahead when dealing with COVID-19, not only related to the acceleration of the pandemic, but also to the prediction of personal protective equipment sets consumption to accommodate the explosive demand. Due to this situation of uncertainty, hospital administration encourages the excess stock of these materials, over-stocking products in some hospitals, and provoking shortages in others. The number of available personal protective equipment sets is one of the three main factors that limit the number of patients at a hospital, as well as the number of available beds and the number of professionals per shift. In this scenario, we developed an easy-to-use expert system to predict the demand for personal protective equipment sets in hospitals during the COVID-19 pandemic, which can be updated in real-time for short term planning. For this system, we propose a naive statistical modeling which combines historical data of the consumption of personal protective equipment sets by hospitals, current protocols for their uses and epidemiological data related to the disease, to build predictive models for the demand for personal protective equipment in Brazilian hospitals during the pandemic. We then embed this modeling in the free Safety-Stock system, which provides useful information for the hospital, especially the safety-stock level and the prediction of consumption/demand for each personal protective equipment set over time. Considering our predictions, a hospital may have its needs related to specific personal protective equipment sets estimated, taking into account its historical stock levels and possible scheduled purchases. The tool allows for adopting strategies to control and keep the stock at safety levels to the demand, mitigating the risk of stock-out. As a direct consequence, it also enables the interchange and cooperation between hospitals, aiming to maximize the availability of equipment during the pandemic.

Difficulties encountered during the pandemic reported by dentists

To evaluate the economic and psychological repercussions, among other difficulties encountered during the COVID-19 pandemic in a group of dentists. Cross-sectional descriptive observational study. An online questionnaire was applied to dentists from the "Rigoberto Caballero" Central Police Hospital (HCPRC) of Asunción-Paraguay that was distributed between July and September 2021. It consisted of 32 closed questions distributed in 5 sections: sociodemographic data, economic effects of the pandemic, psychological effects, contagion, and experiences with respect to the clinic. The data were analyzed with the Epi Info version 7 program and the results are represented in tables, the Fisher's exact test and the Chi-square test were also used. 78 dentists participated, 78.2% female, 56.4% from the 35-45 age group. 88.5% reported a decrease in income in private practice and the majority had to resort to another source to be able to cover daily expenses. Most reported having suffered symptoms of anxiety and depression during the pandemic and felt the need to consult a psychiatrist. It was reported an increase in the demand for Personal Protective Equipment (PPE) and an increase in its costs. Almost half of all dentists reported getting COVID-19. The pandemic had a considerable impact on HCPRC dentists, causing financial problems, psychological repercussions and difficulties with prices and a shortage of PPE.
