Hepatitis B Awareness and Vaccination Patterns among Healthcare Workers in Africa.

ABSTRACT: Hepatitis B virus (HBV) vaccination patterns and the understanding of its risks among healthcare workers (HCWs) is a critical step to decrease transmission. However, the depth of this understanding is understudied. We distributed surveys to HCWs in 12 countries in Africa. Surveys had nine multiple-choice questions that assessed HCWs' awareness and understanding of HBV. Participants included consultants, medical trainees, nurses, students, laboratory personnel, and other hospital workers. Surveys were completed anonymously. Fisher's exact test was used for analysis, with a P-value of < 0.05 considered significant; 1,044 surveys were collected from Kenya, Egypt, Sudan, Tanzania, Ethiopia, Uganda, Malawi, Madagascar, Nigeria, Cameroon, Ghana, and Sierra Leone. Hepatitis B virus serostatus awareness, vaccination rate, and vaccination of HCWs' children were 65%, 61%, and 48%, respectively. Medical trainees had higher serostatus awareness, vaccination rate, and vaccination of their children than HCWs in other occupations (79% versus 62%, P < 0.001; 74% versus 58%, P < 0.001; and 62% versus 45%, P = 0.006, respectively). Cost was cited as the most frequent reason for non-vaccination. West African countries were more aware of their serostatus but less often vaccinated than East African countries (79% versus 59%, P < 0.0001 and 52% versus 60%, P = 0.03, respectively). West African countries cited cost as the reason for non-vaccination more than East African countries (59% versus 40%, P = 0.0003). Our study shows low HBV serostatus awareness and vaccination rate among HCWs in Africa, and reveals gaps in the perception and understanding of HBV prevention that should be addressed to protect HCWs and improve their capacity to control HBV infection.

Project description:IntroductionThe hepatitis B virus (HBV) is a blood-borne virus that can be transmitted by percutaneous and mucocutaneous contact with infected bodily fluid. Healthcare workers (HCWs) are more exposed to HBV infection. They must have a thorough understanding of HBV infection since they can contract and spread the virus. In this study, we systematically reviewed all published evidence on the seroprevalence of Hepatitis B virus (HBV) infection among HCWs. and synthesize evidence on the association between knowledge and awareness with HBV infection.MethodsWe searched PubMed, EMBASE, Cochrane Library and Scopus for studies reporting on HBV seroprevalence from January 1997 to September 2021 among healthcare workers. We used random-effects meta-analyses to estimate the pool prevalence of HBV infection.ResultsWe identified 25 studies that met our inclusion criteria, with data on 10,043 adults from 11 countries and two regions: Africa and Asia. The overall seroprevalence of HBV was 5.0% (95% confidence interval [CI] 3.6%), with Africa reporting higher estimates (5.0%, 95% CI 3.7%) than Asia population (4.0%, 95% CI 1.9%). The highest pooled prevalence estimate in African countries came from studies published in the Cameroon region (8.0%, 95% CI 5-10%) while the lowest came from Ethiopia (4.0%, 95% CI 2.6%). The overall seroprevalence estimates in the African population were significantly higher than those in the Asian group. Studies in Africa found that the average knowledge and seroprevalence were 1.4% and 11.0%, respectively where, eight studies (53.3%) reported good knowledge and seven studies (46.7%) reported average knowledge. In Asia, two studies (40.0%) reported good knowledge, one study (20.0%) reporting average knowledge, and two studies (40.0%) reporting poor knowledge. African studies demonstrated good knowledge despite the fact that their HBV infection rate was higher than 6.7%.ConclusionAfrica and Asia have the highest seroprevalence of HBV infection. Improving the comparability of epidemiological and clinical studies constitutes an important step forward. More high-quality data is needed to improve the precision of burden estimates.Systematic review registrationPROSPERO CRD42021279905.

Project description:BackgroundWorld Health Organization and Centers for Disease Control and Prevention recommend all health professionals to get vaccinated against hepatitis B virus before they start the clinical attachments during their stay in the medical school. However, only 18-39% of healthcare workers in low- and middle-income countries received the vaccine. Therefore, this study aims to determine the attitude and vaccination status of health professionals working at Adama General Hospital and Medical College.MethodsAn institution-based cross-sectional study was conducted from December 2016 to February 2017 with 403 health professionals working at Adama General Hospital and Medical College. Data were collected using self-administered questionnaire distributed at the participant's work unit and analyzed using SPSS version 20. Multiple logistic regression analysis was conducted to identify factors that affect the complete vaccination status and p value < 0.05 was considered statistically significant.ResultThe prevalence of complete vaccination against hepatitis B virus was 25.6%. The most frequently mentioned reasons for not being vaccinated were high cost of the vaccine (41%) and unavailability of the vaccine (36%). More than three-fourths (77.8%) of study participants strongly agreed that hepatitis B is a major public health threat and there was tendency among participants to believe that their profession will put them at increased risk of acquiring the disease (strongly agreed: 75.9%). Attending infection-prevention training [AOR = 2.3; 95% CI, 1.24-6.31], history of exposure to risky behavior [AOR = 5.5; 95% CI, 2.86-9.29], and long years of work experience [AOR = 3.1; 95% CI, 1.98-5.24] were statistically significant with complete vaccination status.ConclusionOnly one-quarter of health professionals received the recommended full dose of the vaccine. Sustained hepatitis B vaccination programs for healthcare workers need to be established by collaboration of different stakeholders to optimize health professionals' safety against this contagious infection.

Project description:BackgroundThe WHO and CDC recommend that HCWs who are at risk of HBV infection should vaccinate as adults early in their career by receiving 3 doses of HB vaccine at a schedule of months 0,1,6 and perform post-vaccination serological testing 1-2 months after vaccination. This study assessed adherence to all three components of the HBV vaccination program.MethodsThe study was a hospital-based analytical cross-sectional study involving 340 HCWs who were randomly selected. A pretested questionnaire was used to collect data which was analyzed using SPSS version 21. The proportion of HCWs adhering to the three components of the HBV vaccination protocol was computed. The multivariable analysis procedure identified the factors associated with overall adherence. Odds ratios were estimated with corresponding confidence intervals with the level of significance set at 0.05.ResultsHBV vaccination coverage was 60.9 % and adherence to 3-doses, 0,1,6 vaccination schedules and post-vaccination serological testing were 46.8 %, 38 % and 13 % respectively. Overall adherence was intermediate at the population level with only 6.2 % of the study participants adhering to all three components of the HBV vaccination protocol. HCWs who had low-risk perception for HBV had the lowest odds of completely adhering to all three indicators recommended for HBV vaccination (aOR = 0.15; 95 %CI = 0.04-0.58). Also, male HCWs have lower odds of adhering to all three components of HBV vaccination compared to their female counterparts (aOR = 0.65; 95 %CI = 1.17-2.50).ConclusionAdherence to the three components of HBV vaccination recommended for HCWs is low in this study. Failure to receive the recommended three-dose series of HBV vaccine at the recommended 0,1,6 schedule has implications for achieving seroprotection or development of antibodies against HBV. Failure to perform post-vaccination testing 1-2 months after HBV vaccination has implications for timely PEP management following occupational exposures. All three components of an ideal HBV vaccination program are important and should be used collectively to guide facility led HCW vaccination programs. Occupational health and safety programs, Infection prevention and control, as well as health promotion campaigns in health facilities, should promote adherence to all three components of HBV vaccination programs.
