Hepatitis B vaccine uptake among healthcare workers in a referral hospital, Accra

Self-reported exposure to blood and body fluids and serological evidence of lifetime exposure to hepatitis B virus among health care workers in Ghana: a cross-sectional study

INTRODUCTION

In Sub-Saharan Africa alone, about 40-65% of Hepatitis B Virus infections among HCWs were a result of percutaneous occupational exposures to contaminated blood and body fluids of patients. Occupational exposure to blood and body fluids among healthcare workers is on the rise in Ghana. However, the relationship between self-reported exposures to blood and body fluids suspected to be contaminated with the hepatitis B virus and actual serological evidence of exposure remains unknown. The aim of the study however was to assess the self-reported exposure to HBV as against the serological evidence of lifetime exposure to HBV and associated factors among Ghanaian HCWs.

METHODS

The study was a cross-sectional analytical survey that involved 340 HCWs who were recruited using a simple random sampling procedure from six cadres of staff from five districts in Greater Accra. The participants were surveyed using a validated instrument and 5mls of venous blood was aseptically withdrawn for qualitative detection of Anti-HBc. SPSS version 23.0 was used to analyze the data to obtain proportions, odds ratios and their corresponding confidence intervals with the level of significance set at 0.05.

RESULTS

The response rate was 94% with Nurses and Doctors in the majority with a mean age of 35.6 ± 7.2. Self-reported exposure to HBV was 63% whereas lifetime exposure to HBV (Anti-HBc) prevalence was 8.2% (95% CI = 5.0-11.0%). Females were 60% less likely to be exposed to HBV (aOR = 0.4; 95% CI = 0.1-0.9) than their male counterparts. HCWs without training in the prevention of blood-borne infections had almost three times higher odds of being exposed to HBV in their lifetime (aOR = 2.6; 95% CI = 1.0-6.4).

CONCLUSIONS

The findings of this study suggest that self-reported exposure to HBV-contaminated biological materials was high with a corresponding high lifetime exposure to HBV. The female gender was protective of anti-HBc acquisition. Apart from direct interventions for preventing occupational exposures to HBV in the healthcare setting, periodic training of all categories of healthcare workers in infection prevention techniques could significantly reduce exposure to the Hepatitis B virus.

Hepatitis B in Healthcare Personnel: An Update on the Global Landscape

Despite the outstanding progress that has been made in the prevention, detection, and management of hepatitis B during the past decades, hepatitis B remains a problem among healthcare personnel (HCP) in many countries. We reviewed studies on all aspects of hepatitis B in HCP published from 2017 through April 2023. They revealed wide variations on the prevalence of infection among HCP, ranging from 0.6% in Europe to >8.7% in Africa, almost always in association with very low vaccination rates. Many studies found a significant association between HCP's knowledge about hepatitis B and hepatitis B vaccines, their vaccination status, and practices. This research also discloses global inequities regarding vaccination policies against hepatitis B, free-of-charge vaccinations, and access to post-exposure prophylaxis (PEP). Strategies to prevent and manage accidental exposures are needed in order to reduce the burden of hepatitis B on HCP, while written policies for all aspects of infection prevention, protective equipment, and PEP should be available. Lastly, HCP should be accordingly educated. These are all imperative given the decline of routine vaccinations in the COVID-19 era, particularly in countries with fragile vaccination programs, and the disruptions of interventions for hepatitis B that are expected to provide a pool of virus transmission to future generations.

HBV Infection Is an Intermediate-Risk Disease, Whereas Anaemia Is a Mild-to-Moderate Public Health Problem in Young Ghanaian Adults: A Four-Year Retrospective Analysis of Students' Medical Records

Background

In sub-Saharan Africa, malaria, chronic viral diseases, nutritional deficiencies, and haemoglobinopathies are common causes of anaemia. Continual surveillance data is required to situate the anaemia and infectious disease burden within a given population. This study determined the 4-year trends of anaemia, hepatitis B virus (HBV), and HCV infections and factors associated with anaemia in young Ghanaian adults.

Methods

This retrospective study analysed the medical records of 21,716 fresh students at the University of Cape Coast. Data was presented as percentages and line graphs to show the yearly trends in anaemia, HBV, and HCV infections. Binary logistic regression was used to determine the increased odds of anaemia in participants.

Results

Although the 4-year anaemia prevalence was 14.2% (95% CI: 0.1403-0.1498), anaemia prevalence in women and men were 24.1% (95% CI: 0.2387-0.2562) and 6.6% (95% CI:0.0616-0.0705), respectively. Anaemia prevalence consistently remained mild (males) and moderate (females) public health problem over the four-year period. Adolescents were more represented in the anaemic group (18.7% prevalence), 70.9% of them being females. The prevalence of HBV and HCV infections were 5.4% (95% CI:0.0506-0.0567) and 0.9% (95% CI: 0.0082-0.0108), respectively; only 0.1% of participants had HBV and HCV coinfection. Males were more represented in both HBV (71.2%) and HCV (63.7%) infection groups. Moreover, 15.8% of the participants who were seropositive for HBsAg self-reported having previously been vaccinated, suggesting a breakthrough infection and/or vaccine nonresponse. Furthermore, female (COR: 4.545; p < 0.001), teenagers (COR: 1.697; p < 0.001), 20-29 years (COR: 1.221; p = 0.035), and positive sickling slide test (COR: 1.176; p = 0.003) were statistically significantly associated with increased odds of anaemia.

Conclusion

Intentional preventative public health campaigns regarding anaemia, HBV, and HCV infection should, respectively, target females and young adult males to increase chances of making real change in behavioural attitudes in these at-risk groups.

Hepatitis B infection prevention: Audit of selected healthcare facilities in the Greater Accra Region, Ghana

Introduction

The risk of occupational exposure to Hepatitis B Virus (HBV) is high among healthcare workers (HCWs), especially in developing countries like Ghana where the prevalence of HBV is high. Unfortunately, in such regions, HCW protection does not appear to be a priority, and healthcare facilities (HFs) have been reported to have unsatisfactory levels of implementing preventive strategies to protect HCWs from blood-borne infections including HBV.

Methods

A cross-sectional and Q audit was performed involving 255 HFs selected by proportional allocation and systematic random sampling. Data was collected using a structured pretested questionnaire with HF managers being the respondents. Data were analysed using IBM ® SPSS® (Statistical Package for the Social Sciences, version 21.0) where univariate, bivariate, and multivariate analysis was done with the level of significance set at <0.05.

Results

Overall adherence to recommended strategies, structures, and programs for HBV prevention among the HFs was generally low, with a mean score of 37.02 (95% CI = 33.98-40.05). There was a statistically significant difference in the level of adherence between the HF categories (F = 9.698; P = <0.001). Being a hospital (OR = 3.9: CI = 1.68-9.29), possessing infection, prevention and control (IPC) guidelines (OR = 6.69: CI = 3.29-13.63) as well as having functional IPC committees in place (OR = 7.9: CI = 3.59-17.34) were associated with good adherence to HF-level HBV preventive strategies.

Conclusion

Overall adherence to HF-level prevention of HBV is sub-optimal. Higher-level facilities were better resourced with HBV vaccine and Hepatitis B immunoglobulin (HBIG). Adherence to HBV prevention strategies depends on the type of HF and the availability of IPC committees and their respective IPC coordinators.

Health care workers' reactions to the newly introduced hepatitis B vaccine in Kalulushi, Zambia: Explained using the 5A taxonomy

Introduction

Hepatitis B virus (HBV) is highly infectious and deadly disease that is transmitted through blood and body fluids. Health care workers (HCWs) have a high risk of contracting HBV in health care settings, the Hep-B vaccine one of the recommended prevention intervention/tools. However, uptake of the vaccine among HCWs remains low in Sub-Saharan Africa. We aimed to explore the barriers and facilitators to uptake of the vaccine offered free of charge to HCWs and nursing students in Kalulushi district, Copperbelt Province of Zambia.

Methods

A total of 29 in-depth interviews (IDIs), either in person or via telephone, with participants before and after they received the vaccines were used to collect the data. We analysed the barriers and facilitators to full or partial vaccination using Penchasky and Thomas's (1981) 5A's (Access, Affordability, Awareness, Acceptance and Activation) taxonomy framework for vaccine hesitancy.

Results

All participants had access to the vaccine, and it was free of charge, making it affordable. Regarding awareness, all participants were aware of HBV infection as an occupational hazard, however, HCWs felt that more sensitization would be needed to increase awareness and knowledge of the vaccine. Acceptability of the vaccine was high among all completers and some non-completers as they felt it was safe and offered them protection. One non-completer felt coerced to accept the first dose due to supervisor expectations and would have preferred to have been given more time to decide. Most felt that vaccination should be compulsory for HCWs. Lastly, activation (vaccine uptake) among non-completers was hindered by late or no notification of appointments as the main reason for not completing the full vaccination schedule. HCWs advised that for countrywide roll-out, at least one weeks' notification would be necessary for HCWs to plan and be mentally prepared to be at their workstations when the vaccination is taking place.

Conclusions

The need to offer the vaccine free of charge locally to ensure easy access and affordability is essential to increase vaccine uptake. Vaccination policies and guidelines for health workers, ongoing training and knowledge sharing are required. Involving trained champions in the facility can also help encourage HCWs to get vaccinated.

Occupational health hazards among healthcare providers and ancillary staff in Ghana: a scoping review

OBJECTIVE

The strict implementation of occupational health and safety policy curbs exposure to occupational hazards. However, empirical evidence is lacking in the Ghanaian context. This review primarily aimed to explore exposure to occupational hazards among healthcare providers and ancillary staff in Ghana.

DESIGN

A scoping review was conducted based on Arksey and O'Malley's methodological framework and Levac et al's methodological enhancement.

DATA SOURCES

Searches were conducted of the PubMed, MEDLINE, CINAHL, Embase, PsycINFO and Scopus databases, as well as Google Scholar and websites of tertiary institutions in Ghana, for publications from 1 January 2010 to 30 November 2021.

ELIGIBILITY CRITERIA

Quantitative studies that were published in the English language and focused on occupational exposure to biological and/or non-biological hazards among healthcare professionals in Ghana were included.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers extracted the data based on the type of occupational exposure and descriptive characteristics of the studies. The data are presented in tables and graphs. A narrative summary of review findings was prepared based on the review research questions.

RESULTS

Our systematic search strategy retrieved 507 publications; however, only 43 met the inclusion criteria. A little over one-quarter were unpublished theses/dissertations. The included studies were related to biological, psychosocial, ergonomic and other non-biological hazards. 55.8% of the studies were related to exposure to biological hazards and related preventive measures. In general, health workers were reported to use and comply with control and preventive measures; however, knowledge of control and preventive measures was suboptimal.

CONCLUSION

Work is needed to address the issue of occupational health hazard exposure in Ghana's health system. More research is needed to understand the extent of these exposures and their effects on the health system.

Level of screening for and vaccination against hepatitis B among healthcare workers in the Eastern Democratic Republic of the Congo: a public health concern

Background

In low resource settings in sub-Saharan Africa healthcare workers (HCW) have a high risk of contracting hepatitis B infection. Vaccination of HCWs is to protect them from acquisition of hepatitis B from patients.

Objective

To evaluate the hepatitis B virus (HBV) serological and vaccination status of HCWs in the Butembo Antenna in the Eastern Democratic Republic of Congo (DR Congo) and to investigate the factors influencing hepatitis screening and vaccination.

Methods

A cross-sectional study using a structured questionnaire was carried out from 1^st to 30^th April 2021 among consenting HCWs in Butembo (≥18 years of age). Data was analysed using SPSS version 23.

Results

Of 373 participants, 178 (47.7%) had already been screened for HBV. Screening was more likely for HCWs in a rural or publicly owned facility (P<0.05). A total of 25 (6.7%) HCWs were fully vaccinated against HBV; the factors associated with full vaccination were: prior screening for HBV (odds ratio: 9.03 (2.51–38.61), P<0.0001), prior knowledge of the value of post-exposure prophylaxis (odds ratio 12.9 (2.89–80.44), P=0.0004), prior knowledge of hepatitis B vaccine benefits (adjusted odds ratio: 4.54 (1.66–13.05), P=0.002) and prior exposure to hepatitis B infection (adjusted odds ratio: 2.61 (1.08–6.39), P=0.039).

Conclusion

Screening and vaccination rates of HCWs for HBV are extremely low, and not high enough to prevent the spread of this serious illness and its complications. There is a dire need to increase vaccination rates among HCWs in Eastern DR Congo. The DRC government should issue vaccination against HBV as a recommendation at the national level.

A novel model of care for simplified testing of HBV in African communities during the COVID-19 pandemic in Spain

Chronic hepatitis B virus (HBV) infection is a major public health threat for migrant populations in Spain and efforts to scale up testing are needed to reach the WHO elimination targets. The Hepatitis B Virus Community Screening and Vaccination in Africans (HBV-COMSAVA) study aims to use point-of-care testing and simplified diagnostic tools to identify, link to care, or vaccinate African migrants in Barcelona during the COVID-19 pandemic. From 21/11/20 to 03/07/2021, 314 study participants were offered HBV screening in a community clinic. Rapid tests for HBsAg screening were used and blood samples were collected with plasma separation cards. Patients received results and were offered: linkage to specialist care; post-test counselling; or HBV vaccination in situ. Sociodemographic and clinical history were collected and descriptive statistics were utilized. 274 patients were included and 210 (76.6%) returned to receive results. The HBsAg prevalence was 9.9% and 33.2% of people had evidence of past resolved infection. Overall, 133 required vaccination, followed by post-test counselling (n = 114), and linkage to a specialist (n = 27). Despite the COVID-19 pandemic, by employing a community-based model of care utilizing novel simplified diagnostic tools, HBV-COMSAVA demonstrated that it was possible to diagnose, link to care, and vaccinate African migrants in community-based settings.

Occupational injuries among health care workers at a public hospital in Ghana

INTRODUCTION

information on occupational injuries to health care workers (HCWs) in Africa is limited. We sought to determine the prevalence of occupational injuries among HCWs at a Ghanaian hospital, determine the most common types of injuries, and assess HCWs' knowledge regarding occupational safety.

METHODS

we interviewed 246 HCWs at a government hospital regarding occupational injuries during the prior year. The sample included: nurses (77.6%), physicians (9.3%), laboratory staff (5.7%), and non-clinical staff (6.9%).

RESULTS

the 12-month prevalence of occupational injury was 29.7%. Incidence was 1.63 injuries per person-year. Leading mechanisms were needlesticks (35.4% of injuries), cuts from sharp objects (34.6%), hit by object (25.2%), and violence (24.4%). Most (62.2%) respondents had training in occupational safety. Most reported adherence to safety practices, including properly disposing sharps (86.6%) and using personal protective equipment (85.8%). However, there were gaps in knowledge. Few HCWs knew the officer in-charge for post-exposure prophylaxis (5.3%) or that there was a hospital occupational safety unit (26.4%). Many (20.8%) reported difficulty in seeking care for their injury. On multivariable analysis, correlates of injury included stress at work (aOR 2.68; 95% CI 1.26, 5.71) and being a laboratory worker (aOR 3.26; 95% CI 1.02, 10.50).

CONCLUSION

occupational injuries to HCWs were unacceptably frequent. There is, however, a solid foundation to build on. Most HCWs had training in occupational safety and many reported adherence to safety practices. Health care workers need to be better informed of existing resources. Care for injuries needs to be improved, such as by increasing capacity for post-exposure prophylaxis.

Screening, Vaccination Uptake and Linkage to Care for Hepatitis B Virus among Health Care Workers in Rural Sierra Leone

This study reports on the prevalence and risk factors of chronic HBV among health care workers (HCWs) in a rural secondary hospital in Sierra Leone. Additionally, data on the uptake of HBV vaccination among negatively tested HCWs and on the linkage to care among positively tested HCWs are presented. In December 2019, 781 HCWs were invited to a screening and vaccination campaign at Koidu Government Hospital in Kono District. For each HCW, demographic information and data on their HBV risk history were captured, followed by a hepatitis B surface antigen (HBsAg) test. HCWs with a negative test result were offered an HBV vaccine on the same day, after one and six months. HCWs that were HBsAg positive were linked to a free HBV clinic. In total, 80% (632) of HCWs were screened. Among the screened, 97% had never received an HBV vaccine and 10.3% (n = 65) had chronic HBV. The following characteristics were associated with being HBsAg positive: aged less than 30 years old (aOR 2.17, CI 1.16–4.03, p = 0.01), male gender (aOR 2.0, CI 1.06–3.78, p = 0.03), working experience of 1–4 years (aOR 3.99, CI 1.15–13.73, p = 0.03) and over 9 years (aOR 6.16, CI 1.41–26.9, p = 0.02). For HBsAg-negative HCWs (n = 567), 99.8% (n = 566), 97.5% (n = 553) and 82.7% (n = 469) received their first, second and third dose of the vaccine, respectively. For HBsAg-positive HCWs (n = 65), 73.9% (n = 48) were successfully linked to an HBV clinic for further care. Most HCWs are unvaccinated for HBV, and the HBV prevalence amongst this at-risk group is high. Uptake of vaccination and linkage to care was successful.

Increasing hepatitis B vaccination coverage of healthcare workers - global lessons for South Africa

Healthcare workers (HCWs) are at high risk of contracting hepatitis B (HB), a severe blood-borne vaccine-preventable disease, caused by HB virus (HBV) infection. Low HB vaccine (HepB) coverage has resulted in suboptimal protection and high HBV infection rates in South African HCWs. Studies from Africa have identified cost; unavailability/lack of access to HepB; and lack of awareness/knowledge of HB and HepB, as barriers to HCW uptake. Studies from Europe show little difference in HepB coverage between countries mandating versus recommending HepB. Providing easy and sustained access to free HepB to student HCWs, together with education about HB and HepB, are recommended to create demand for HepB. Only if this fails should mandatory vaccination be considered.
