[PMID: 33845486 PMCID: PMC8083292 DOI: 10.1093/inthealth/ihab017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 01/26/2021] [Accepted: 03/10/2021] [Indexed: 12/23/2022] Open
Abstract
Background Healthcare professionals represent a vulnerable group in terms of responding to COVID-19. Knowledge can influence healthcare professionals through adoption of the correct attitudes and practices. The aim of this study was to evaluate, by a questionnaire, the perceptions of physicians about their level of knowledge as well as conditions in their workplaces for dealing with COVID-19. Methods A cross-sectional study of Angolan physicians took place from 11 May to 23 June 2020. A questionnaire was electronically shared across social media and via email. Results The sample consisted of 637 valid questionnaires; 53% of respondents were female, 41% were aged 31–40 y and 79% were from Luanda province. About 51% of physicians perceived that they had adequate knowledge about COVID-19 and 64% used personal protective equipment. These figures were higher among specialists from the province of Luanda. About 81% stated that their health units lacked the technical capacity to diagnose COVID-19. Only 35% of health units have chest tomography equipment; 44% are prepared for the care and/or isolation of patients. Only 33% of units are running intensive care units. The main concerns of physicians were training opportunities and limited access to personal protective equipment. Conclusion The results show that it is necessary to strengthen physicians’ knowledge about COVID-19, as well as to improve the conditions of the health units, so as to promote safe practices.

Abstract
This rapid scoping review has informed the development of the November 2020 United Nations Research Roadmap for the COVID-19 Recovery, by providing a synthesis of available evidence on the impact of pandemics and epidemics on (1) essential services and (2) health systems preparedness and strengthening. Emerging findings point to existing disparities in health systems and services being further exacerbated, with marginalized populations and low- and middle-income countries burdened disproportionately. More broadly, there is a need to further understand short- and long-term impacts of bypassed essential services, quality assurance of services, the role of primary health care in the frontline, and the need for additional mechanisms for effective vaccine messaging and uptake during epidemics. The review also highlights how trust—of institutions, of science, and between communities and health systems—remains central to a successful pandemic response. Finally, previous crises had repeatedly foreshadowed the inability of health systems to handle upcoming pandemics, yet the reactive nature of policies and practices compounded by lack of resources, infrastructure, and political will have resulted in the current failed response to COVID-19. There is therefore an urgent need for investments in implementation science and for strategies to bridge this persistent research–practice gap.

Personal protective equipment for reducing the risk of COVID-19 infection among health care workers involved in emergency trauma surgery during the pandemic: An umbrella review. J Trauma Acute Care Surg 2021; 90:e72-e80. [PMID: 33433175 PMCID: PMC7996059 DOI: 10.1097/ta.0000000000003073] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Revised: 11/30/2020] [Accepted: 12/26/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND Health care facilities in low- and middle-income countries are inadequately resourced to adhere to current COVID-19 prevention recommendations. Recommendations for surgical emergency trauma care measures need to be adequately informed by available evidence and adapt to particular settings. To inform future recommendations, we set to summarize the effects of different personal protective equipment (PPE) on the risk of COVID-19 infection in health personnel caring for trauma surgery patients. METHODS We conducted an umbrella review using Living Overview of Evidence platform for COVID-19, which performs regular automated searches in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and more than 30 other sources. Systematic reviews of experimental and observational studies assessing the efficacy of PPE were included. Indirect evidence from other health care settings was also considered. Risk of bias was assessed with the AMSTAR II tool (Assessing the Methodological Quality of Systematic Reviews, Ottawa, ON, Canada), and the Grading of Recommendations, Assessment, Development, and Evaluation approach for grading the certainty of the evidence is reported (registered in International Prospective Register of Systematic Reviews, CRD42020198267). RESULTS Eighteen studies that fulfilled the selection criteria were included. There is high certainty that the use of N95 respirators and surgical masks is associated with a reduced risk of COVID-19 when compared with no mask use. In moderate- to high-risk environments, N95 respirators are associated with a further reduction in risk of COVID-19 infection compared with surgical masks. Eye protection also reduces the risk of contagion in this setting. Decontamination of masks and respirators with ultraviolet germicidal irradiation, vaporous hydrogen peroxide, or dry heat is effective and does not affect PPE performance or fit. CONCLUSION The use of PPE drastically reduces the risk of COVID-19 compared with no mask use in health care workers. N95 and equivalent respirators provide more protection than surgical masks. Decontamination and reuse appear feasible to overcome PPE shortages and enhance the allocation of limited resources. These effects are applicable to emergency trauma care and should inform future recommendations. LEVEL OF EVIDENCE Review, level II.

Abstract
The sustainable development of humanity imposes precise norms regarding the management of natural resources, their extraction, use, and the introduction in a complex, innovative circuit of the waste resulting from exploitation. The paper deals with some aspects related to the sustainable management of general medical waste on the one hand and the medical waste specific to the COVID-19 pandemic, on the other hand. Medical waste requires special treatment given its impact on the environment and on humanity. The management of activities related to its storage, transport, destruction is an important point in the sustainable development of mankind, especially in the current context of the pandemic. Medical waste is in a continuous increase in quantity and involves many effects in various activity fields. Through a scientometric study in the Web of Science—WOS database, the authors identify clusters of keywords, analyze the articles identified in the WOS and identify the main research directions and existing concepts. Corroborating and interpreting the results obtained, three significant trends of approach to medical waste are identified: M—management (1); E—exposure (2); and D—distribution (3). An extensive map of the concepts is made, a narrow map of the concepts used, and a theoretical map of the concepts. The link between medical waste and the development of a sustainable society is demonstrated, and it is possible to open new research directions. The scientometric research undertaken on 1192 WOS articles that were published in 2020 led to the selection of 32, focused on issues related to hazardous medical waste, especially of COVID-19 patients. Following this approach, the authors were able to see, by comparison, the different forms of management of this waste in different countries, thus being able to contribute to the creation of procedures for the collection, storage, and destruction of this hazardous waste, with direct influence on the environment.

Abstract
The World Health Organization (WHO) on December 31, 2019, was informed of several cases of respiratory diseases of unknown origin in the city of Wuhan in the Chinese Province of Hubei, the clinical manifestations of which were similar to those of viral pneumonia and manifested as fever, cough, and shortness of breath. And, the disease caused by the virus is named the new coronavirus disease 2019 and it will be abbreviated as 2019-nCoV and COVID-19. As of January 30, 2020, the WHO classified this epidemic as a global health emergency (Chung et al. in Radiology 295(1):202-207, 2020). It is an international real-life problem. Due to deaths, globally everyone is under fear. Now, it is the responsibility of researchers to give hope to the people. In this article, we aim to better protect people and general pandemic preparedness by predicting the lifetime of the disease-causing virus using three mathematical models. This article deals with a complex real-life problem people face all over the world, an international real-life problem. The main focus is on the USA due to large infection and death due to coronavirus and thereby the life of every individual is uncertain. The death counts of the USA from February 29 to April 22, 2020, are used in this article as a data set. The death counts of the USA are fitted by the solutions of three mathematical models and a solution to an international problem is achieved. Based on the death rate, the lifetime of the coronavirus COVID-19 is predicted as 1464.76 days from February 29, 2020. That is, after March 2024 there will be no death in the USA due to COVID-19 if everyone follows the guidelines of WHO and the advice of healthcare workers. People and government can get prepared for this situation and many lives can be saved. It is the contribution of soft computing. Finally, this article suggests several steps to control the spread and severity of the disease. The research work, the lifetime prediction presented in this article is entirely new and differs from all other articles in the literature.

Infection prevention and control compliance among exposed healthcare workers in COVID-19 treatment centers in Ghana: A descriptive cross-sectional study. PLoS One 2021; 16:e0248282. [PMID: 33690699 PMCID: PMC7943010 DOI: 10.1371/journal.pone.0248282] [Citation(s) in RCA: 44] [Impact Index Per Article: 14.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Accepted: 02/24/2021] [Indexed: 02/07/2023] Open
Abstract
Compliance with infection prevention and control (IPC) protocols is critical in minimizing the risk of coronavirus disease (COVID-19) infection among healthcare workers. However, data on IPC compliance among healthcare workers in COVID-19 treatment centers are unknown in Ghana. This study aims to assess IPC compliance among healthcare workers in Ghana's COVID-19 treatment centers. The study was a secondary analysis of data, which was initially collected to determine the level of risk of COVID-19 virus infection among healthcare workers in Ghana. Quantitative data were conveniently collected using the WHO COVID-19 risk assessment tool. We analyzed the data using descriptive statistics and logistic regression analyses. We observed that IPC compliance during healthcare interactions was 88.4% for hand hygiene and 90.6% for Personal Protective Equipment (PPE) usage; IPC compliance while performing aerosol-generating procedures (AGPs), was 97.5% for hand hygiene and 97.5% for PPE usage. For hand hygiene during healthcare interactions, lower compliance was seen among nonclinical staff [OR (odds ratio): 0.43; 95% CI (Confidence interval): 0.21-0.89], and healthcare workers with secondary level qualification (OR: 0.24; 95% CI: 0.08-0.71). Midwives (OR: 0.29; 95% CI: 0.09-0.93) and Pharmacists (OR: 0.15; 95% CI: 0.02-0.92) compliance with hand hygiene was significantly lower than registered nurses. For PPE usage during healthcare interactions, lower compliance was seen among healthcare workers who were separated/divorced/widowed (OR: 0.08; 95% CI: 0.01-0.43), those with secondary level qualifications (OR 0.08; 95% CI 0.01-0.43), non-clinical staff (OR 0.16 95% CI 0.07-0.35), cleaners (OR: 0.16; 95% CI: 0.05-0.52), pharmacists (OR: 0.07; 95% CI: 0.01-0.49) and among healthcare workers who reported of insufficiency of PPEs (OR: 0.33; 95% CI: 0.14-0.77). Generally, healthcare workers' infection prevention and control compliance were high, but this compliance differs across the different groups of health professionals in the treatment centers. Ensuring an adequate supply of IPC logistics coupled with behavior change interventions and paying particular attention to nonclinical staff is critical in minimizing the risk of COVID-19 transmission in the treatment centers.

Abstract
The world is facing the coronavirus pandemic (COVID-19), which began in China. By August 18, 2020, the United States, Brazil, and India were the most affected countries. Health infrastructure and socioeconomic vulnerabilities may be affecting the response capacities of these countries. We compared official indicators to identify which vulnerabilities better determined the exposure risk to COVID-19 in both the most and least affected countries. To achieve this purpose, we collected indicators from the Infectious Disease Vulnerability Index (IDVI), the World Health Organization (WHO), the World Bank, and the Brazilian Geography and Statistics Institute (IBGE). All indicators were normalized to facilitate comparisons. Speed, incidence, and population were used to identify the groups of countries with the highest and lowest risks of infection. Countries' response capacities were determined based on socioeconomic, political, and health infrastructure conditions. Vulnerabilities were identified based on the indicator sensitivity. The highest-risk group included the U.S., Brazil, and India, whereas the lowest-risk group (with the largest population by continent) consisted of China, New Zealand, and Germany. The high-sensitivity cluster had 18 indicators (50% extra IDVI), such as merchandise trade, immunization, public services, maternal mortality, life expectancy at birth, hospital beds, GINI index, adolescent fertility, governance, political stability, transparency/corruption, industry, and water supply. The greatest vulnerability of the highest-risk group was related first to economic factors (merchandise trade), followed by public health (immunization), highlighting global dependence on Chinese trade, such as protective materials, equipment, and diagnostic tests. However, domestic political factors had more indicators, beginning with high sensitivity and followed by healthcare and economic conditions, which signified a lesser capacity to guide, coordinate, and supply the population with protective measures, such as social distancing.

Abstract
Utilizing the biopsychosocial model and the ecological systems theory, this disquisition explores on the risk factors associated with the COVID-19 pandemic. The discourse shows the interconnectedness of biological, psychological, and social domains in expatiating on the COVID-19 pandemic. It calls for the need to strengthen the resilience of the global community in the face of health outbreaks such as COVID-19. It emphasizes on the perspectives that pandemics are managed before they emerge through building systems that are resilient. Thus, it appreciates the need for a therapeutic milieu as a building block to resilience. The article calls for the adoption of a developmental stance to analyzing health outbreaks and clinical issues. The adumbration shows the reciprocity effects of the health outbreak [macrocosms] and individual factors [microcosms]. To its end, the paper implies that COVID-19 is a call for integration toward effective health planning between social policy formulators, urban and rural planners, epidemiologists, development practitioners, clinicians, researchers to mention but a few. Ultimately, the paper calls for social workers to consider a developmental-clinical social work approach which helps foster "health in all policies" so as to build resilience against the morbus and limit the proliferation of diseases.

Abstract
Background Mismanagement of healthcare waste (HCW) during the COVID-19 pandemic can facilitate the transmission of coronavirus. Regarding this problem, there is gap of evidence in Ethiopia, and this study aimed to assess the HCW generation rate and management in Tepi General Hospital, southwest Ethiopia. Methods Institution-based cross-sectional and case studies were conducted. The total amount of waste generated and its type among various case teams were compared using the Kruskal–Wallis test. Spearman's rank correlation coefficient (r) was used to assess the correlation between the total numbers of patients and the total amount of HCW generated. Qualitative data were transcribed verbatim, translated to English, and analyzed with Open Code version 4.02 software, and content analysis was followed. Results The total mean weight (±SD) of waste generation rate in all service units of the hospital was 492.5 ± 11.5 kg/day. The higher proportion (61.9%) of the total HCW produced was general waste and the remaining (38.1%) was hazardous waste. There was a statistically significant (X2 = 82.1, p < 0.001) difference in daily HCW generation rate among different case teams. Similarly, the hospital waste generation amount and total patient flow had a strong positive linear relationship (r = 0.7, p=0.032). COVID-19-related medical wastes were not properly handled, segregated, stored, and disposed. There was a scarcity of resources needed to manage HCW, and available resources were utilized poorly. Overall, healthcare wastes were managed as usual (pre-COVID-19). Conclusion The mean HCW generation rate in Tepi General Hospital was high. Overall, wastes were mismanaged, and COVID-19-related HCWs have been managed as usual. Availing of important resources and training the concerned bodies should be considered during the crisis of COVID-19.

Pragmatic Recommendations for Infection Prevention and Control Practices for Healthcare Facilities in Low- and Middle-Income Countries during the COVID-19 Pandemic. Am J Trop Med Hyg 2021; 104:25-33.

Abstract
Infection prevention and control (IPC) strategies are key in preventing nosocomial transmission of COVID-19. Several commonly used IPC practices are resource-intensive and may be challenging to implement in resource-constrained settings. An international group of healthcare professionals from or with experience in low- and middle-income countries (LMICs) searched the literature for relevant evidence. We report on a set of pragmatic recommendations for hospital-based IPC practices in resource-constrained settings of LMICs. For cases of confirmed or suspected COVID-19, we suggest that patients be placed in a single isolation room, whenever possible. When single isolation rooms are unavailable or limited, we recommend cohorting patients with COVID-19 on dedicated wards or in dedicated hospitals. We also recommend that cases of suspected COVID-19 be cohorted separately from those with confirmed disease, whenever possible, to minimize the risk of patient-to-patient transmission in settings where confirmatory testing may be limited. We suggest that healthcare workers be designated to care exclusively for patients with COVID-19, whenever possible, as another approach to minimize nosocomial spread. This approach may also be beneficial in conserving limited supplies of reusable personal protective equipment (PPE). We recommend that visitors be restricted for patients with COVID-19. In settings where family members or visitors are necessary for caregiving, we recommend that the appropriate PPE be used by visitors. We also recommend that education regarding hand hygiene and donning/doffing procedures for PPE be provided. Last, we suggest that all visitors be screened for symptoms before visitation and that visitor logs be maintained.

Abstract
BACKGROUND Coronaviruses have caused outbreaks of respiratory disease since the beginning of the 21st century, representing a significant threat to public health. Together, the severe acute respiratory syndrome coronavirus (SARS-CoV), the respiratory syndrome coronavirus (MERS-CoV), and, more recently, the novel coronavirus (SARS-CoV-2) have caused a large number of deaths around the world. Thus, investments in research and the development of strategies aimed at diagnosing, treating, and preventing these infections are urgently needed. OBJECTIVE The objective of this study was to analyze the patents that address pathogenic coronaviruses in Google Patents databases in the last year (2019-2020). METHODS The search strategy was carried out in April 2020, based on the keywords "SARS", "SARS-CoV", "MERS", "MERS-CoV", "SARS-CoV-2" and "COVID-19. Out of the patents examined, 25 were selected for a short description in this study. RESULTS A total of 191 patents were analyzed, 149 of which were related to SARS-CoV, and 29 and 12 were related to MERS-CoV and SARS- CoV2, respectively. The patents addressed the issues of diagnosis, therapeutic agents, prevention and control, along with other applications. CONCLUSION Several promising strategies have been documented in intellectual property databases favoring the need for further studies on the pathogenesis and optimization of the diagnosis and therapeutic treatment for these emerging infections.

Abstract
Since the beginning of the COVID-19 pandemic, there has been intense debate over SARS-CoV-2's mode of transmission and appropriate personal protective equipment for health care workers in low-risk settings. The objective of this review is to identify and appraise the available evidence (clinical trials and laboratory studies on masks and respirators, epidemiological studies, and air sampling studies), clarify key concepts and necessary conditions for airborne transmission, and shed light on knowledge gaps in the field. We find that, except for aerosol-generating procedures, the overall data in support of airborne transmission-taken in its traditional definition (long-distance and respirable aerosols)-are weak, based predominantly on indirect and experimental rather than clinical or epidemiological evidence. Consequently, we propose a revised and broader definition of "airborne," going beyond the current droplet and aerosol dichotomy and involving short-range inhalable particles, supported by data targeting the nose as the main viral receptor site. This new model better explains clinical observations, especially in the context of close and prolonged contacts between health care workers and patients, and reconciles seemingly contradictory data in the SARS-CoV-2 literature. The model also carries important implications for personal protective equipment and environmental controls, such as ventilation, in health care settings. However, further studies, especially clinical trials, are needed to complete the picture.

Preparedness of health facilities providing HIV services during COVID-19 pandemic and assessment of their compliance to COVID-19 prevention measures: findings from the Tanzania Service Provision Assessment (SPA) survey. Pan Afr Med J 2020; 37:18. [PMID: 33343797 DOI: 10.11604/pamj.supp.2020.37.18.25443] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Accepted: 09/26/2020] [Indexed: 11/11/2022] Open
Abstract
Introduction the increased demands of health facilities and workers due to coronavirus overwhelm the already burdened Tanzanian health systems. This study evaluates the current capacity of facilities and providers for HIV care and treatment services and their preparedness to adhere to the national and global precaution guidelines for HIV service providers and patients. Methods data for this study come from the latest available, Tanzania Service Provision Assessment survey 2014-15. Frequencies and percentages described the readiness and availability of HIV services and providers. Chi-square test compared the distribution of services by facility location and availability and readiness of precaution commodities and HIV services by managing authorities. Results availability of latex gloves was high (83% at OPD and 95.3% laboratory). Availability of medical masks, alcohol-based hand rub and disinfectants was low. Availability of medical mask at outpatient department (OPD) was 28.7% urban (23.5% public; 33.8% private, p=0.02) and 13.5% rural (10.1% public; 25.4% private, p=0.001) and lower at laboratories. Fewer facilities in rural area (68.4%) had running water in OPD than urban (86.3%). Higher proportions of providers at public than private facilities in urban (82.8% versus 73.1%) and rural (88.2% versus 81.6%) areas provided HIV test counseling and at least two other HIV services. Conclusion availability of commodities such as medical masks, alcohol-based hand rub, and disinfectant was low while the readiness of providers to multitask HIV related services was high. Urgent distribution and re-assessment of these supplies are necessary, to protect HIV patients, their caregivers, and health providers from COVID-19.

Environmental Disinfection Strategies to Prevent Indirect Transmission of SARS-CoV2 in Healthcare Settings. APPLIED SCIENCES-BASEL 2020.

Abstract
(1) Introduction: The novel respiratory syndrome coronavirus 2 (SARS-CoV-2), also called coronavirus disease 2019 (COVID-19), is rapidly spreading in many countries and represents a public health emergency of international concern. The SARS-CoV-2 transmission mainly occurs from person-to-person via respiratory droplets (direct transmission route), leading to the onset of mild or severe symptoms or even causing death. Since COVID-19 is able to survive also on inanimate surfaces for extended periods, constituting an indirect transmission route, healthcare settings contaminated surfaces should be submitted to specific disinfection protocols. Our review aimed to investigate the existing disinfection measures of healthcare settings surfaces, preventing the nosocomial transmission of SARS-CoV-2. (2) Materials and Methods: We conducted electronic research on PubMed, Scopus, Science Direct, and Cochrane Library, and 120 items were screened for eligibility. Only 11 articles were included in the review and selected for data extraction. (3) Results: All the included studies proposed the use of ethanol at different concentrations (70% or 75%) as a biocidal agent against SARS-CoV-2, which has the capacity to reduce the viral activity by 3 log10 or more after 1 min of exposure. Other disinfection protocols involved the use of chlorine-containing disinfectant, 0.1% and 0.5% sodium hypochlorite, quaternary ammonium in combination with 75% ethanol, isopropyl alcohol 70%, glutardialdehyde 2%, ultraviolet light (UV-C) technology, and many others. Two studies suggested to use the Environmental Protection Agency (EPA)-registered disinfectants, while one article chooses to follow the WST-512-2016 Guidance of Environmental and Surfaces Cleaning, Disinfection and Infection Control in Hospitals. (4) Conclusion: Different surface disinfection methods proved to reduce the viral activity of SARS-CoV-2, preventing its indirect nosocomial transmission. However, more specific cleaning measures, ad hoc for the different settings of the healthcare sector, need to be formulated.
