Knowledge of infection prevention and control among healthcare workers and factors influencing compliance: a systematic review

The Factors Associated With Performance Among Infection Prevention and Control Linked Nurse During Covid-19 Pandemic

Background

Infection Prevention and Control Linked Nurses (IPCLN) are the spearhead of implementing the Infection Control Prevention Program. The performance of nurses in preventing and controlling infections during the Covid-19 pandemic greatly influenced the quality of services.

Objective

This study aimed to determine the factors that influence the performance of IPCLN during the Covid-19 pandemic.

Methods

Cross-sectional study was performed on 34 nurses at Cicendo Eye Hospital with a total sampling technique. The questionnaire in this study included knowledge, motivation, supervision, and the performance of nurses which had previously been tested with these characteristics with a result of Cronbach's alpha of 0.75. Data were analyzed using univariate, bivariate, and multivariate analyses.

Results

The mean score of IPCLN knowledge in this study was 14.82 ± 4.01, motivation 92.47 ± 15.85, supervision 34.74 ± 5.89, and performance 7.94 ± 2.71. There is a relationship between knowledge (p = .000), motivation (p = .000), and supervision (p = .000) on nurse performance. Motivation is the dominant factor influencing IPCLN performance compared to knowledge and supervision (Stand. Estimate = 0.5121; 95% CI = 0.1301-0.487; p < .001).

Conclusion

Motivation is a dominant factor in IPCLN performance in this study. However, hospital management needs to maximize and make policies to improve IPCLN performance in terms of motivation. These policies can be through providing incentives for nurses, developing free continuing education programs, and issuing funds for nursing education scholarships.

Designing an optimal infection prevention service: Part 1

Background

Healthcare-associated infections (HCAIs) pose a significant threat to the health and safety of patients, staff, and visitors. Infection prevention and control (IPC) teams play a crucial role in ensuring that systems and processes are in place to keep everyone safe within the healthcare environment.

Aim

The aim of this study was to identify components of infection prevention services, priorities, indicators of successes and how they are measured, and facilitators and barriers to success.

Methods

A survey questionnaire was developed and circulated to infection prevention leaders and managers.

Findings/results

Seventy IPC leaders/managers completed the survey. Participants were responsible for a range of IPC services within and across healthcare organisations, with significant variations to IPC delivery components. Additionally, a range of budget availability was reported. Several IPC service requirements were considered core work of IPC teams, including providing IPC advice and support, surveillance and audit and education and training.

Discussion

An optimal IPC service needs to be in place to ensure HCAIs are minimised or prevented. In a post pandemic era, this is more important than ever before. This is also as crucial for the health and wellbeing of those working in IPC, who have endured unprecedented demand for their services during the pandemic.

Evaluation of the characteristics of infection prevention and control programs and infection control committees in Brazilian hospitals: A countrywide cross-sectional study

Objective

Data are scarce regarding hospital infection control committees and compliance with infection prevention and control (IPC) recommendations in Brazil, a country of continental dimensions. We assessed the main characteristics of infection control committees (ICCs) on healthcare-associated infections (HAIs) in Brazilian hospitals.

Methods

This cross-sectional study was conducted in ICCs of public and private hospitals distributed across all Brazilian regions. Data were collected directly from the ICC staff by completing an online questionnaire and during on-site visits through face-to-face interviews.

Results

In total, 53 Brazilian hospitals were evaluated from October 2019 to December 2020. All hospitals had implemented the IPC core components in their programs. All centers had protocols for the prevention and control of ventilator-associated pneumonia as well as bloodstream, surgical site, and catheter-associated urinary tract infections. Most hospitals (80%) had no budget specifically allocated to the IPC program; 34% of the laundry staff had received specific IPC training; and only 7.5% of hospitals reported occupational infections in healthcare workers.

Conclusions

In this sample, most ICCs complied with the minimum requirements for IPC programs. The main limitation regarding ICCs was the lack of financial support. The findings of this survey support the development of strategic plans to improve IPCs in Brazilian hospitals.

Healthcare workers' experiences of caring for patients colonized with carbapenemase-producing Enterobacterales (CPE) in an acute hospital setting - a scoping review

Carbapenemase-producing Enterobacterales (CPE) is an increasing public health concern; these bacteria are highly transmissible in hospital environments and the number of patients with these multidrug-resistant bacteria is rising. Healthcare workers caring for patients colonized with CPE offer insight into care delivery and processes in the hospital setting. The aim of this review was to explore healthcare workers' experiences of caring for patients colonized with CPE. A scoping review method was employed and seven electronic databases (CINAHL, Academic Search Complete, Cochrane, Embase, Medline, Web of Science and Scopus) and four grey literature databases (Open Grey, Grey Literature Report, Clinical trials. gov and WHO International Clinical Trials Registry Platform) were searched using specific search terms and inclusion/exclusion criteria. A PRISMA flow diagram was used to illustrate the process of article selection and thematic analysis used to form themes. Three studies met the criteria to be included in this review. Two main themes were identified from analysing the articles: 'Safeguarding' and 'Power of Knowledge'. The desire to protect themselves, their families and patients was evident from the studies. Healthcare workers were aware of the importance on infection prevention and control measures such as hand hygiene, in preventing the transmission of CPE, however barriers to these were identified, such as time constraints. In conclusion, healthcare workers have negative associations when it comes to caring for patients with CPE. Very little research has been conducted in the area and there is an opportunity to further explore the experience of healthcare workers caring for patients with CPE to identify opportunities for improvement and support of staff.

Workplace policies and quality of working life (QoWL) during the COVID-19 pandemic in Jordanian hospitals

BACKGROUND

Many healthcare organizations place a high value on quality of work-life (QoWL). The healthcare system's long-term sustainability and capability to offer high-quality services to patients depend on improving QoWL for their healthcare workers.

OBJECTIVE

The study aimed to explore the impact of Jordanian hospitals' workplace policies and measures in three main domains: (I) Infection prevention and control (IPC) measures, (II) Supply of personal protective equipment (PPE), and (III) COVID-19 precautionary measures on the QoWL among healthcare workers during the COVID-19 pandemic.

METHODS

A cross-sectional survey was conducted from May to June 2021 through an online self-reported questionnaire (Google Form) targeting hospital healthcare professionals working at Jordanian hospitals (public, private, military, and university). The study used a valid work-related quality of life (WRQoL) scale to study the QoWL.

RESULTS

A total of 484 HCWs in Jordanian hospitals participated in the study with a mean age of (34.8 ± 8.28 years). 57.6% of the respondents were females. 66.1% were married, with 61.6% having children at home. An average QoWL among healthcare workers in Jordanian hospitals during the pandemic was observed. The study results also showed a significant positive correlation between workplace policies (IPC measures, supply of PPE, and COVID-19 preventive measures) and the WRQoL among healthcare workers.

CONCLUSION

Our findings highlighted the vital need for QoWL and psychological well-being support services for healthcare staff during pandemics. Improved IPC systems and other precautionary measures at the national and hospital management levels are required to help minimize the stress and fear that healthcare workers experience and lower the risk of COVID-19 and future pandemics.

Effectiveness of Infection Control Teams in Reducing Healthcare-Associated Infections: A Systematic Review and Meta-Analysis

The infection control team (ICT) ensures the implementation of infection control guidelines in healthcare facilities. This systematic review aims to evaluate the effectiveness of ICT, with or without an infection control link nurse (ICLN) system, in reducing healthcare-associated infections (HCAIs). We searched four databases to identify randomised controlled trials (RCTs) in inpatient, outpatient and long-term care facilities. We judged the quality of the studies, conducted meta-analyses whenever interventions and outcome measures were comparable in at least two studies, and assessed the certainty of evidence. Nine RCTs were included; all were rated as being low quality. Overall, ICT, with or without an ICLN system, did not reduce the incidence rate of HCAIs [risk ratio (RR) = 0.65, 95% confidence interval (CI): 0.45-1.07], death due to HCAIs (RR = 0.32, 95% CI: 0.04-2.69) and length of hospital stay (42 days vs. 45 days, p = 0.52). However, ICT with an ICLN system improved nurses' compliance with infection control practices (RR = 1.17, 95% CI: 1.00-1.38). Due to the high level of bias, inconsistency and imprecision, these findings should be considered with caution. High-quality studies using similar outcome measures are needed to demonstrate the effectiveness and cost-effectiveness of ICT.

Factors affecting compliance with infection prevention and control standard precautions among healthcare workers in Songwe region, Tanzania

Background

Compliance with infection prevention and control standard precautions (IPCSPs) remains a major challenge in many countries including Tanzania. Lack of compliance exposes healthcare workers (HCWs) and patients to a high risk of developing healthcare-associated infections (HAIs) including antimicrobial-resistant microorganisms which can contribute to the spread of antimicrobial resistance (AMR). This study investigated compliance with IPCSPs and associated factors among HCWs in public healthcare facilities (HFs) in Songwe Region, Tanzania between January and March 2021.

Methods

A cross-sectional study was conducted in all 5 districts in Songwe Region, involved 400 HCWs from difference healthcare facilities (HFs) including dispensaries, health centres and hospitals. The Compliance with Standard Precautions scale (CSPS) tool developed by WHO was used. Descriptive and modified Poisson regression analysis was done. A P-value of less than 0.05 indicated statistical significance.

Results

Only 22.5% (90/400) of HCWs had high compliance (above 80%) to IPCSPs. The majority of HCWs reported highest compliance on discarding used needles/sharps into sharps containers (94%), the lowest IPCSPs compliance was for the correct handling of spills, taking a shower after extensive splashing and not re-using disposable masks, 8%, 28.5% and 34% respectively. Attending IPC training or an IPC seminar in the previous year (ARR=2.97 [1.87-4.72] P<0.001), the number of years of work experience (ARR=2.08 [1.22-3.54] P=0.007), and having experienced a needlestick injury (ARR=0.62 [0.40-0.95] P=0.028), were identified as predictors of HCWs compliance with IPCSPs.

Conclusion

The majority of HCWs in Songwe region had low compliance with IPCSPs according to national standards. IPC training and the number of years of work experience predicted high compliance with IPCSPs. Capacity building initiatives, mentorship and supportive supervision should be emphasised for all HCWs in all HFs.

Occupational risk of COVID-19 across pandemic waves: a two-year national follow-up study of hospital admissions

OBJECTIVE

Assuming that preventive measures to mitigate viral transmission of SARS-CoV-2 at the workplace may have been improved in the course of the COVID-19 pandemic, we examined the occupational risk of COVID-19 related hospital admission across the four pandemic waves in Denmark between week 8, 2020, and week 50, 2021.

METHODS

The study included 4416 cases of COVID-19 related hospital admissions among 2.4 million Danish employees aged 20-69 with follow-up in 2020 through 2021. At-risk industrial sectors and a reference population were defined a priory by a job-exposure matrix on occupational risk for COVID-19. Incidence rate ratios (IRR) and potential effect modification by pandemic wave were computed with Poisson regression adjusted for demographic, social and health factors including completed COVID-19 vaccination.

RESULTS

We observed an overall elevated relative risk in four of six at-risk industrial sectors, but the pandemic wave only modified the risk among healthcare employees, where the excess risk from a high initial level declined to background levels during the latest waves in models not adjusting for COVID-19 vaccination. In social care, education and transport, the elevated risk was not modified by pandemic wave.

CONCLUSION

Danish healthcare employees were to some extent protected against occupational transmission of SARS-CoV-2 during the two last pandemic waves even though the absolute risk conferred by occupation may not have been eliminated. Early vaccination of this group seems not to be the only explanation. The risk in other sectors remained elevated indicating a need to revisit preventive measures.

Institutional Factors Associated with Infection Prevention and Control Practices Globally during the Infectious Pandemics in Resource-Limited Settings

Healthcare-associated infections lead to considerable morbidity, a prolonged hospital stay, antibiotic resistance, long-term disability, mortality and increased healthcare costs. Based on the literature, some individual and socio-demographic factors including knowledge, age and length of service or work experience, gender and type of profession influence compliance with infection prevention and control procedures. In addition, organizational culture, which refers to the assumptions, values, and norms shared among colleagues, can influence an individual's thinking and healthcare workers' behavior, either positively or negatively. Infection control practices based on the perspective of patients, hospital management and healthcare workers may help develop a better understanding of the factors influencing compliance with infection prevention and control policies and guidelines.

Colorectal cancer in patients with SARS-CoV-2: a systematic review and meta-analysis

Background

Patients with colorectal cancer (CRC) are more likely to develop severe course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and experience increased risk of mortality compared to SARS-CoV-2 patients without CRC.

Objectives

To estimate the prevalence of SARS-CoV-2 infection in CRC patients and analyse the demographic parameters, clinical characteristics and treatment outcomes in CRC patients with COVID-19 illness.

Methods

For this systematic review and meta-analysis, we searched Proquest, Medline, Embase, Pubmed, CINAHL, Wiley online library, Scopus and Nature for studies on the incidence of SARS-CoV-2 infection in CRC patients, published from December 1, 2019 to December 31, 2021, with English language restriction. Effect sizes of prevalence were pooled with 95% confidence intervals (CIs). Sub-group analyses were performed to minimize heterogeneity. Binary logistic regression model was used to explore the effect of various demographic and clinical characteristics on patient’s final treatment outcome (survival or death).

Results

Of the 472 papers that were identified, 69 articles were included in the systematic review and meta-analysis (41 cohort, 16 case-report, 9 case-series, 2 cross-sectional, and 1 case-control studies). Studies involving 3362 CRC patients with confirmed SARS-CoV-2 (all patients were adults) were analyzed. The overall pooled proportions of CRC patients who had laboratory-confirmed community-acquired and hospital-acquired SARS-CoV-2 infections were 8.1% (95% CI 6.1 to 10.1, n = 1308, 24 studies, I² 98%, p = 0.66), and 1.5% (95% CI 1.1 to 1.9, n = 472, 27 studies, I² 94%, p < 0.01). The median patient age ranged from 51.6 years to 80 years across studies. The majority of the patients were male (n = 2243, 66.7%) and belonged to White (Caucasian) (n = 262, 7.8%), Hispanic (n = 156, 4.6%) and Asian (n = 153, 4.4%) ethnicity. The main source of SARS-CoV-2 infection in CRC patients was community-acquired (n = 2882, 85.7%; p = 0.014). Most of those SARS-CoV-2 patients had stage III CRC (n = 725, 21.6%; p = 0.036) and were treated mainly with surgical resections (n = 304, 9%) and chemotherapies (n = 187, 5.6%), p = 0.008. The odd ratios of death were significantly high in patients with old age (≥ 60 years) (OR 1.96, 95% CI 0.94–0.96; p < 0.001), male gender (OR 1.44, 95% CI 0.41–0.47; p < 0.001) CRC stage III (OR 1.54, 95% CI 0.02–1.05; p = 0.041), CRC stage IV (OR 1.69, 95% CI 0.17–1.2; p = 0.009), recent active treatment with chemotherapies (OR 1.35, 95% CI 0.5–0.66; p = 0.023) or surgical resections (OR 1.4, 95% CI 0.8–0.73; p = 0.016) and admission to ICU (OR 1.88, 95% CI 0.85–1.12; p < 0.001) compared to those who survived.

Conclusion

SARS-CoV-2 infection in CRC patient is not uncommon and results in a mortality rate of 26.2%. Key determinants that lead to increased mortality in CRC patients infected with COVID-19 include older age (≥ 60 years old); male gender; Asian and Hispanic ethnicity; if SARS-CoV-2 was acquired from hospital source; advanced CRC (stage III and IV); if patient received chemotherapies or surgical treatment; and if patient was admitted to ICU, ventilated or experienced ARDS.

Flu Vaccination among Healthcare Professionals in Times of COVID-19: Knowledge, Attitudes, and Behavior

The seasonal flu vaccine is the most important way to prevent influenza epidemics, so it is useful to increase the awareness of health professionals. The aim of our study is to evaluate knowledge, attitudes, and behavior about flu vaccination among healthcare professionals in times of COVID-19. Methods: A cross sectional study was carried out between November 2020 and April 2021. Participants were recruited in teaching hospital ‘Policlinico Umberto I’ of Rome. A survey of 24 questions about flu vaccination was administered, evaluating their knowledge, attitude, and practice about this topic. Results: 872 healthcare professionals were involved in the study (36.9% men, 63.1% women). More than 90% of the HCWs, especially physicians, recognize the importance of getting influenza vaccination: The main reasons for not getting vaccinated were fear of vaccine side effects (20.3%) and fear of the needle (6.4%). Nevertheless, 40.7% of the healthcare providers consider mandatory vaccination as unethical, especially if they work in low-intensity wards. Conclusion: a high percentage of healthcare workers agree with the importance of influenza vaccination and only a small percentage is still opposed. It is therefore important to continue to promote the influenza vaccination through communication and health education programs.

Safety and efficacy in the nursing care of people with rheumatic diseases on janus kinase inhibitor therapy

Nurses's support of patients needs an evidence base as much as that of specialists management. However, some more practical aspects need specific questions that are not addressed in medical societies' recommendations. Our objective was to investigate the effect of Janus kinase inhibitors (jakinibs) on efficacy, safety, infections, cardiovascular risk, vaccination, pregnancy and lactation, interactions, surgery, and switch in adult patients with rheumatic diseases. We used the methodology for rapid reviews. Medline was searched for systematic reviews of randomised clinical trials and longitudinal observational studies reporting on the target aspects, without limits, yielding 540 titles, of which 70 articles were selected for detailed reading after the screening of title and abstract. In the case of no systematic review being published on a specific question, we resorted to the information provided by primary studies. The efficacy and safety profiles are similar to that of TNF-inhibitors to which they are compared in most studies; however, there is an increased risk of herpes zoster infections with jakinibs. The evidence on pregnancy, surgery and switches between jakinibs is very limited, although, so far, there are no major issues to inform patients about or to implement specific measures. In general, evidence to support nursing management in patients being treated with jakinibs is of moderate quality and scarce, ought to the recent incursion of jakinibs as a treatment.

Meta-analysis: risk of hepatitis C virus infection associated with hospital-based invasive procedures

BACKGROUND

Healthcare settings, where invasive procedures are frequently performed, may play an important role in the transmission dynamics of blood-borne pathogens when compliance with infection control precautions is suboptimal.

AIMS

To understand and quantify the role of hospital-based invasive procedures on hepatitis C virus (HCV) transmission.

METHODS

We conducted a systematic review and meta-analysis to identify recent studies reporting association measures of HCV infection risk that are linked to iatrogenic procedures. Based on expert opinion, invasive procedures were categorised into 10 groups for which pooled measures were calculated. Finally, the relationship between pooled measures and the country-level HCV prevalence or the Healthcare Access and Quality (HAQ) index was assessed by meta-regression.

RESULTS

We included 71 studies in the analysis. The most frequently evaluated procedures were blood transfusion (66 measures) and surgery (43 measures). The pooled odds ratio (OR) of HCV infection varied widely, ranging from 1.46 (95% confidence interval: 1.14-1.88) for dental procedures to 3.22 (1.7-6.11) for transplantation. The OR for blood transfusion was higher for transfusions performed before 1998 (3.77, 2.42-5.88) than for those without a specified/recent date (2.20, 1.77-2.75). In procedure-specific analyses, the HCV infection risk was significantly negatively associated with the HAQ for endoscopy and positively associated with HCV prevalence for endoscopy and surgery.

CONCLUSIONS

Various invasive procedures were significantly associated with HCV infection. Our results provide a ranking of procedures in terms of HCV risk that may be used for prioritisation of infection control interventions, especially in high HCV prevalence settings.

Knowledge and determinants of infection prevention and control compliance among nurses in Yendi municipality, Ghana

Background

Knowledge of and compliance to infection prevention and control (IPC) guidelines are crucial to curbing hospital acquired infections (HAIs). Globally, about 7–10% of patients suffer HAIs. However, there is limited evidence on nurses’ knowledge and adherence to IPC guidelines. Therefore, this study assessed the knowledge and determinants of IPC compliance among nurses in Yendi Municipality, Northern Ghana.

Methods

We conducted a quantitative cross-sectional study among 209 nurses of the Yendi Municipal hospital, using an adapted questionnaire. We collected and analysed data using SPSS version 26. Socio-demographics, knowledge level and compliance to IPC guidelines were assessed using descriptive statistics. The minimum scores for knowledge and compliance were 0 each with maximum scores being 10 and 8 respectively. Using binary multivariate logistic regression, the determinants of IPC compliance were analysed and odds ratios reported at 95% confidence intervals.

Results

The nurses had high mean and standard deviation scores for knowledge (7.26 ± 1.4) and compliance to IPC guidelines (5.41 ± 1.5). Females (aOR: 0.33; 95%CI: 0.17–0.64; p = 0.001) were significantly less likely to comply to IPC guidelines. Nurses working in Maternity/Labour wards (aOR: 8.31; 95%CI: 2.46–28.15; p = 0.001) and Outpatient Department (OPD)/Psychiatry (aOR: 5.00; 95%CI: 1.42–17.62; p = 0.012) were associated with higher odds of complying to IPC guidelines. Availability of IPC guidelines (aOR: 3.48; 95%CI: 1.13–10.72; p = 0.030) in a working department influenced compliance to IPC measures.

Conclusion

The study revealed high knowledge and high compliance regarding IPC among nurses in the Yendi Municipal Hospital. A person’s working department and the availability of IPC guidelines were key determinants for high compliance to IPC measures. However, knowledge of IPC did not influence compliance to IPC guidelines. The Municipal and Regional Health directorates, should therefore ensure adequate logistic flow, provision of IPC guidelines and proper supervision to ensure maximum compliance with IPC guidelines, particularly among paediatric, medical and surgical wards nurses as well as degree holding nurses.

Effective factors in people's preventive behaviors during covid-19 pandemic: a systematic review and meta-synthesis

Background

The overwhelming outbreak of covid-19 has forced governments all over the world to consider different measures to face this challenging situation. A vitally important element to the declining transmission of viruses is changing behaviors based on reliable information. This study was designed and implemented to identify factors affecting the preventive behaviors during the covid-19 pandemic.

Methods

This thematic synthesis was carried out in order to create a set of central themes that summarize all of the issues raised in the articles reviewed in this study. We used PRISMA 2020 guidelines to direct this systematic review and meta synthesis. The process of analyzing data includes three different stages: 1) creating codes; 2) production of descriptive themes; 3) and finally, the creation of analytical themes. The Standards for Reporting Qualitative Research checklist was used to evaluate the articles' quality.

Results

Five central themes emerged from 8 included articles, (1) Social factors (subthemes: environmental context, political leadership, multimedia), (2) Cultural factors (subthemes: national culture, religious culture, the family beliefs, work culture, foreign culture), (3) Economic factors (subthemes: economic situation of the individual, the government supports, infrastructures), (4) Personal factors (subthemes: people experiences, cognitive ability, physical factors, different motivational level, sense of responsibility, risk management, and self-management skills), and (5) Knowledge and Education factors (subthemes: access to information, skill training). Furthermore, SRQR items that were weakly reported were “researcher characteristics and reflexivity”, “Sampling strategy”, “Data collection methods”, “Data analysis”, and “techniques to enhance trustworthiness.

Conclusion

Health policymakers and other public health officials in various countries can use the factors listed to develop appropriate, evidence-based policies. They should investigate behavioral characteristics in their community based on their abilities, and then design and implement appropriate executive actions.

SARS-CoV-2 antibody response after mRNA vaccination in healthcare workers with and without previous COVID-19, a follow-up study from a university hospital in Poland during 6 months 2021

Introduction

Healthcare workers (HCWs) from the beginning of the pandemic have been at risk of exposure to SARS-CoV-2, so they were vaccinated as first.

Objectives

The purpose of the study was to determine the level of antibodies against SARS-CoV-2 in HCWs before and after vaccination with mRNA preparations according to previous COVID- 19.

Patients and methods

The HCWs from the University Hospital in Krakow completed two surveys: the baseline survey before receiving the first dose of vaccine (in January 2021) and the follow-up survey in June 2021. In parallel, two blood samples were collected from each participant at baseline and at follow-up. Total anti-SARS-CoV-2 antibody levels were measured using the ECLIA technique.

Results

At baseline, 41.1% of HCWs had positive antibody test results, and at follow-up, the vaccinated HCWs had almost 100 times higher antibody levels than the unvaccinated HCWs. Participants under 30 years of age had significantly higher antibody levels in June than older HCWs. Among participants with positive antibody test results in January, HCWs who had experienced asymptomatic COVID-19 had more than five times higher antibody levels in June than HCWs self-reported severe COVID-19. In total, 86.9% of HCWs received Comirnaty or Spikevax. The incidence rate of COVID-19 in the unvaccinated vs. vaccinated group was 13 times higher, 20.5% and 1.9% respectively.

Conclusions

These results confirm the effectiveness of vaccination in the prevention of COVID-19 in HCWs. It is worth getting vaccinated regardless of previous infection. Furthermore, vaccination among HCWs under 30 years of age induced more effective antibody production compared to older individuals.

A Comprehensive Overview of the Newly Emerged COVID-19 Pandemic: Features, Origin, Genomics, Epidemiology, Treatment, and Prevention

The coronavirus disease 2019 (COVID-19), a life-threatening pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has resulted in massive destruction and is still continuously adding to its death toll. The advent of this global outbreak has not yet been confirmed; however, investigation for suitable prophylaxis against this lethal virus is being carried out by experts all around the globe. The SARS-CoV-2 belongs to the Coronaviridae superfamily, like the other previously occurring human coronavirus variants. To better understand a new virus variant, such as the SARS-CoV-2 delta variant, it is vital to investigate previous virus strains, including their genomic composition and functionality. Our study aimed at addressing the basic overview of the virus’ profile that may provide the scientific community with evidence-based insights into COVID-19. Therefore, this study accomplished a comprehensive literature review that includes the virus’ origin, classification, structure, life cycle, genome, mutation, epidemiology, and subsequent essential factors associated with host–virus interaction. Moreover, we summarized the considerable diagnostic measures, treatment options, including multiple therapeutic approaches, and prevention, as well as future directions that may reduce the impact and misery caused by this devastating pandemic. The observations and data provided here have been screened and accumulated through extensive literature study, hence this study will help the scientific community properly understand this new virus and provide further leads for therapeutic interventions.

Willingness and SARS-CoV-2 Vaccination Coverage among Healthcare Workers in China: A Nationwide Study

Background: The SARS-CoV-2 vaccine has been widely rolled out globally in the general populations. However, specific data on vaccination confidence, willingness or coverage among health care workers (HCWs) has been less reported. Methods: A cross-sectional online survey was conducted to specify the basic data and patterns of vaccination confidence, willingness and coverage among HCWs nationwide. Results: In total, 2386 out of 2583 (92.4%) participants were enrolled for analysis, and the rates of confidence in vaccine, professional institutes and government were 75.1%, 85.2% and 85.4%, respectively. The overall vaccination coverage rate was 63.6% which was adjusted as 82.8% for participants under current medical conditions or having contraindications. Confidence in vaccine safety was shown to be the most related factor to willingness among doctors, nurses, medical technicians and hospital administrators, while confidence in vaccine effectiveness as well as trust in government played the key role in formulating public health employees' willingness. 130 (7.1% of 1833) participants reporting willingness still not been vaccinated regardless of contraindications. Multivariate analysis among willingness participants showed that males, aged over 30 years, public health employees and higher vaccination confidence had significantly higher vaccination rates with ORs (95% confidence intervals) as 1.64 (1.08-2.49), 3.14 (2.14-4.62), 2.43 (1.46-4.04) or 2.31 (1.24-4.33). Conclusions: HCWs' confidence, willingness and coverage rates to the vaccine were generally at high levels. Heterogeneity among HCWs should be considered for future vaccination promotion strategies. The population's confidence in vaccination is not only the determinant to their willingness, but also guarantees their actual vaccine uptake.

Coinfections with Bacteria, Fungi, and Respiratory Viruses in Patients with SARS-CoV-2: A Systematic Review and Meta-Analysis

Background: Coinfection with bacteria, fungi, and respiratory viruses in SARS-CoV-2 is of particular importance due to the possibility of increased morbidity and mortality. In this meta-analysis, we calculated the prevalence of such coinfections. Methods: Electronic databases were searched from 1 December 2019 to 31 March 2021. Effect sizes of prevalence were pooled with 95% confidence intervals (CIs). To minimize heterogeneity, we performed sub-group analyses. Results: Of the 6189 papers that were identified, 72 articles were included in the systematic review (40 case series and 32 cohort studies) and 68 articles (38 case series and 30 cohort studies) were included in the meta-analysis. Of the 31,953 SARS-CoV-2 patients included in the meta-analysis, the overall pooled proportion who had a laboratory-confirmed bacterial infection was 15.9% (95% CI 13.6–18.2, n = 1940, 49 studies, I² = 99%, p < 0.00001), while 3.7% (95% CI 2.6–4.8, n = 177, 16 studies, I² = 93%, p < 0.00001) had fungal infections and 6.6% (95% CI 5.5–7.6, n = 737, 44 studies, I² = 96%, p < 0.00001) had other respiratory viruses. SARS-CoV-2 patients in the ICU had higher co-infections compared to ICU and non-ICU patients as follows: bacterial (22.2%, 95% CI 16.1–28.4, I² = 88% versus 14.8%, 95% CI 12.4–17.3, I² = 99%), and fungal (9.6%, 95% CI 6.8–12.4, I² = 74% versus 2.7%, 95% CI 0.0–3.8, I² = 95%); however, there was an identical other respiratory viral co-infection proportion between all SARS-CoV-2 patients [(ICU and non-ICU) and the ICU only] (6.6%, 95% CI 0.0–11.3, I² = 58% versus 6.6%, 95% CI 5.5–7.7, I² = 96%). Funnel plots for possible publication bias for the pooled effect sizes of the prevalence of coinfections was asymmetrical on visual inspection, and Egger’s tests confirmed asymmetry (p values < 0.05). Conclusion: Bacterial co-infection is relatively high in hospitalized patients with SARS-CoV-2, with little evidence of S. aureus playing a major role. Knowledge of the prevalence and type of co-infections in SARS-CoV-2 patients may have diagnostic and management implications.
